By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. + +When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. + +To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. + +For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. + +We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. + +Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. + +Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. + +The precise terms and conditions for copying, distribution and modification follow. + +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION +0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. + +1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. + +You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. + +2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: + + +a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. + +b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. + +c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) +These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. +Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. + +3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: + +a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, + +b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, + +c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) +The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. +If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. + +4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. + +5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. + +6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. + +7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. + +This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. + +8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. + +9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. + +10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. + +NO WARRANTY + +11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + +12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + + +END OF TERMS AND CONDITIONS diff --git a/contrib/other/sdlquake-1.0.9/Makefile.Solaris b/contrib/other/sdlquake-1.0.9/Makefile.Solaris new file mode 100644 index

Don't + bother id software about it. Bug reports will be ignored. + +PORT DETAILS +------------ + + There are a few major difference between this port and the + vanilla Quake/QuakeWorld available on the internet. For + optimum performance, you should copy everything to a directory + on your local system before starting play so that you are + not mounting files from a remote filesystem. + + In order to use this program, you need the files pak0.pak + and pak1.pak in the id1 directory found on a registered copy of + Quake. You can ftp them to your Solaris host from a Windows95 + machine for example. The files must be in an id1 subdirectory from + the directory you install Quake/QuakeWorld, and all file names must + be lowercase. Add on packages such as ThreeWave CTF work fine as + well, just place such addon packages in their own directory as you + would on a Windows95 installation. But again, make sure all files + are lowercase. + + COMMAND LINE FLAGS: + + +pixel_multiply + + You can magnify the screen by using this flag: + + Ex: % quake +pixel_multiply 2 + + You can also use this command (without the dash) + from the Quake console. pixel_multiply is a Quake + cvar and is saved from session to session in the + config.cfg file. + + -winsize + + Set the size of the window when you start + + -count_frames + + See how many frames per second you're getting + + GAME SETTINGS + + mouse binding + + You can bind and unbind the mouse to the Quake window + by using the Use Mouse selection in the Options menu, + or with the "_windowed_mouse" command in the console, + ex "_windowed_mouse 1" Now, moving the mouse will move + your player. Use "_windowed_mouse 0" to unbind. You + can bind or alias this to a key. + + Example command: + + % quake.xil +pixel_multiply 2 -winsize 400 300 + +WHAT IS "QUAKEWORLD" AND HOW DO I USE IT? +----------------------------------------- + + In a nutshell, QuakeWorld is an extension of Quake that is + much more user friendly. It allows the user to dynamically + download changes from the server, such as new maps and new + weapons while inside the Quake client. It is not directly + compatible with Quake (ie, you can't connect to a Quake server + from a QuakeWorld client) but in general it is superior to + Quake. QuakeWorld also offers much smoother play over the + Internet by using client prediction. For more information, + check out http://www.quakeworld.net/. + + In order to use it, you must make a copy of the "qw" + directory. Any new stuff that is downloaded from a QuakeWorld + server will be stored in this directory. All regular Quake + flags apply so you can use the same command line as before. + + Example command: + + % qwcl.xil +pixel_multiply 2 -winsize 400 300 + +WHERE CAN I FIND OUT ABOUT... +----------------------------- + + If you've got questions about Quake, rest assured that there + are answers out there.

Termination or +expiration of this Agreement, either by Id Software or +automatically, shall not create any liability against Id Software. +Upon expiration or earlier termination of this Agreement, Licensee +shall have no further right to exercise the rights licensed +hereunder or otherwise acquired in relation to this Agreement. + + 7. INDEMNIFICATION. Licensee hereby agrees to +indemnify, hold harmless and defend Id Software and Id Software's +predecessors, successors, assigns, officers, directors, +shareholders, employees, agents, representatives, licensees, +sublicensees, distributors, attorneys and accountants +(collectively, the "Id Related Parties") from and against any and +all damages, claims, losses, causes of action, liabilities, +lawsuits, judgments and expenses (including, without limitation, +reasonable attorneys' fees and expenses) arising from, relating to +or in connection with a breach of this Agreement by Licensee and +arising from, relating to or in connection with the Licensee's use +or non-use of the Authorized Copy (collectively, the "Claims"). Id +Software agrees to notify Licensee of any such Claims within a +reasonable time after Id Software learns of same. Licensee, at its +own expense, shall defend Id Software and the Id Related Parties +from any and all Claims. Id Software and the Id Related Parties +reserve the right to participate in any defense of the Claims with +counsel of their choice, and at their own expense. In the event +Licensee fails to provide a defense, then Licensee shall be +responsible for paying the attorneys' fees and expenses incurred by +Id Software and the Id Related Parties regarding the defense of the +Claims. Id Software and the Id Related Parties, as applicable, +agree to reasonably assist in the defense of the Claims. No +settlement by Licensee of any Claims shall be valid unless Licensee +receives the prior written consent of Id Software and the Id +Related Parties, as applicable, to any such settlement. + + 8. CONFIDENTIALITY. It is understood and agreed that +any proprietary information of Id Software that may from time to +time be made available or become known to Licensee is to be treated +as confidential, is to be used solely in connection with Licensee's +performance under this Agreement, and is to be disclosed only to +employees of Licensee who have a need for access. Such proprietary +information shall include, but not be limited to, trade secrets, +release information, financial information, personnel information, +and the like. Reasonable measures shall be taken by Licensee to +protect the confidentiality of Id Software's proprietary +information and any memoranda or papers containing proprietary +information of Id Software's that Licensee may receive are to be +returned to Id Software upon request. Licensee's obligations and +duties under this paragraph shall survive expiration or earlier +termination of this Agreement. Licensee shall obtain from its +employees an undertaking in a form which may be supplied by Id +Software, and which is subject to Id Software's prior written +approval, not to use or disclose to any third party any information +or knowledge concerning the business of Id Software which may be +communicated to such employees. + + 9. LIMITATION OF LIABILITY. ID SOFTWARE EXPRESSLY +DISCLAIMS ALL WARRANTIES NOT PROVIDED BY ID SOFTWARE HEREUNDER. +UNDER NO CIRCUMSTANCES SHALL ID SOFTWARE BE LIABLE TO LICENSEE FOR +ACTUAL, SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES OR +ANY OTHER DAMAGES, WHETHER OR NOT ID SOFTWARE RECEIVES NOTICE OF +ANY SUCH DAMAGES. + + 10. COMPLIANCE WITH APPLICABLE LAWS. In performing +under this Agreement, Licensee agrees to comply with all applicable +laws, [including, without limitation, 22 U.S.C., 2778 and 22 +U.S.C. C.F.R. Parts 120-130 (1995)] regulations, ordinances and +statutes, including, but not limited to, the import/export laws and +regulations of the United States and its governmental and +regulatory agencies (including, without limitation, the Bureau of +Export Administration and the U.S. Department of Commerce) and all +applicable international treaties and laws. Further, Licensee +shall defend, indemnify and hold harmless Id Software from any and +all sales tax, tariffs and/or duties in connection with Licensee's +performance hereunder. + + 11. SPECIFIC UNDERTAKINGS BY LICENSEE. In addition to +the obligations of Licensee otherwise set forth in this Agreement, +during the term of this Agreement, and thereafter where specified, +Licensee agrees that: + + a. It will not attack the title of Id Software to the +Subject Game or the Trademark and any copyright, patent or +trademark or other intellectual property right related thereto and +it will not attack the validity of the license granted hereunder +during the term hereof or thereafter; and + + b. It will promptly inform Id Software of any +unauthorized use of the Authorized Copy, the Subject Game and the +Trademark and any portions thereof and reasonably assist Id +Software in the enforcement of any rights Id Software may have +against such unauthorized users. + + 12. FINANCIAL OBLIGATIONS AND ACCOUNTING. + + a. Payment of Royalties. Licensee agrees to pay Id +Software a royalty ("Royalty") at the rate of twelve and one-half +percent (12.5%) of Net Income. The term "Net Income" shall mean +all revenue received by Licensee from the commercial use of the +Authorized Copy, less only Licensee's actual, documented costs +relating directly to such use. A Royalty shall only be due for +those months in which Licensee's gross revenue from QUAKE +distribution exceeds U.S. Five Thousand Dollars ($5,000.00) and in +such months Licensee shall pay a full Royalty on all revenue +received. + + b. Rendition of Statements. Licensee shall account to +Id Software with regard to transactions hereunder within forty-five +(45) days following the conclusion of each calendar quarter. +Licensee hereby represents and warrants that such statements of +account to be prepared shall be true and correct. The accounts +shall show in summary form the appropriate calculations relating to +the computation of Royalties, if any. The statements shall also +show the gross revenue received by Licensee per month. The +Royalties payable to Id Software hereunder shall be remitted with +the particular statement indicating such amount to be due. All +statements hereunder shall be deemed rendered when deposited, +postage prepaid, in the United States mail, addressed to Id +Software at Id Software's address set forth on the signature page +hereof. + + c. Books of Account and Audits. Licensee shall keep +books of account relating to the commercial use of the Authorized +Copy on the basis of generally accepted accounting principles and +shall maintain such books of account for a period of at least two +(2) years after the expiration or earlier termination of this +Agreement; provided, however, that Licensee shall not be required +to keep such records longer than seven (7) years from their date of +origination. Id Software may, upon reasonable notice and at its +own expense, audit the applicable records at Licensee's office, in +order to verify statements rendered hereunder. Any such audit +shall take place during reasonable business hours and in such +manner so as not to interfere with Licensee's normal business +activities. Id Software agrees that such information inspected +and/or copied on behalf of Id Software hereunder shall be used only +for the purpose of determining the accuracy of the statements, and +shall be revealed only to such officers, directors, employees, +agents and/or representatives of Id Software as necessary to verify +the accuracy of the statements. If in an audit of Licensee's books +and records it is determined that there is a short fall of ten +percent (10%) or more in Royalties reported for any calendar +quarter, in addition to payment of such short fall and interest as +may be due, as provided herein, Licensee shall reimburse Id +Software for the full out-of-pocket costs of the audit including +reasonable travel costs and expenses; provided, however, that the +amount of reimbursement paid by Licensee shall not exceed U.S. +Fifteen Thousand Dollars ($15,000.00) for any audit. + + d. Payment of the Royalty. Licensee assumes all risks +associated with fluctuations in foreign currency exchange rates. +Licensee shall pay and agrees to pay all sums due Id Software in +United States Dollars. With respect to Royalties due for +commercial use outside the United States, other currencies shall be +exchanged at the expense of Licensee into United States Dollars +using the bid price quoted at the Citibank, N.A. of New York, New +York, for the purchase of United States Dollars at the close of +business on the last day of the calendar quarter during which any +amounts accrue. Payment of the Royalties shall be made in Dallas +County, Texas. + + e. Interest. If Id Software does not receive the +applicable Royalty payment on or before the due date of such +payment, Licensee agrees to pay and shall pay interest on Royalties +owed to Id Software from such date as specified in the following +sentence at a rate per annum equal to the Index Rate. For purposes +of clarification, the interest will begin to accrue on the first +(1st) day following the due date of the Royalty payment, unless the +Royalty payment is paid timely. The "Index Rate" shall be the +prime rate as published in The Wall Street Journal's "Money Rates" +table. If multiple prime rates are quoted in the table, then the +highest prime rate will be the Index Rate. In the event that the +prime rate is no longer published in the "Money Rates" table, then +Id Software will choose a substitute Index Rate which is based upon +comparable information. The applicable interest rate will be +determined and take effect on the first day of each month. + + NOTHING HEREIN SHALL BE CONSTRUED AS A REQUEST OR DEMAND BY +ID SOFTWARE OF INTEREST AT A RATE HIGHER THAN ALLOWED BY APPLICABLE +LAW. IT IS THE INTENT OF THE PARTIES HERETO THAT NO INTEREST BE +CHARGED HEREUNDER WHICH EXCEEDS THE MAXIMUM RATE ALLOWED BY +APPLICABLE LAW. IF THE RATE REFERENCED ABOVE EXCEEDS THE MAXIMUM +RATE ALLOWED BY APPLICABLE LAW, THEN THE INTEREST RATE MADE +APPLICABLE HEREIN SHALL BE THE MAXIMUM RATE ALLOWED BY APPLICABLE +LAW. + + 13. SUBLICENSE. Licensee shall not be entitled to +sublicense any of its rights under this Agreement. + + 14. GOODWILL. Licensee recognizes the great value of +the goodwill associated with the Subject Game and the Trademark, +and acknowledges that such goodwill, now existing and hereafter +created, exclusively belongs to Id Software and that the Trademark +has acquired a secondary meaning in the mind of the public. + + 15. REMEDIES. In the event of a breach of this +Agreement by Id Software, Licensee's sole remedy shall be to +terminate this Agreement. In the event of a breach by Licensee of +this Agreement, Id Software may pursue the remedies to which it is +entitled under applicable law, including, but not limited to, +termination of this Agreement. Licensee agrees that its failure to +comply with the terms of this Agreement upon expiration or earlier +termination hereof or Licensee's unauthorized use of the Authorized +Copy may result in immediate and irreparable damage to Id Software +for which there is no adequate remedy at law, and in the event of +such failure by Licensee, Id Software shall be entitled to +injunctive relief. Pursuit of any remedy by Id Software shall not +constitute a waiver of any other right or remedy of Id Software +under this Agreement or under applicable law. Termination of this +Agreement shall not be a pre-condition to Id Software pursuing its +other remedies for breach. + + 16. LICENSEE'S WARRANTIES. Licensee warrants and +represents that it has full legal rights to enter into this +Agreement and to perform its obligations hereunder and that it will +comply, at all times during the terms of this Agreement, with all +applicable laws, as set forth hereinabove. + + 17. BANKRUPTCY. If Licensee's liabilities exceed its +assets, or if Licensee becomes unable to pay its debts as they +become due or if Licensee files for voluntary bankruptcy, or is +placed in bankruptcy which is not dissolved or dismissed after +thirty (30) days from the petition filing date, or if Licensee +becomes insolvent, or makes an assignment for the benefit of its +creditors or an arrangement pursuant to any bankruptcy laws or if +Licensee discontinues its business or if a receiver is appointed +for its business, this Agreement shall automatically terminate, +without notice, and become null and void; provided, however, all +duties of Licensee upon termination or expiration of this Agreement +shall continue in full force and effect. + + 18. ENTIRE AGREEMENT AND ASSIGNMENT. This Agreement +constitutes the entire understanding between Licensee and Id +Software regarding the Subject Game. Each and every clause of this +Agreement is severable from the whole and shall survive unless the +entire Agreement is declared unenforceable. No prior or present +agreements or representations shall be binding upon any of the +parties hereto unless incorporated in this Agreement. No +modification or change in this Agreement shall be valid or binding +upon the parties unless in writing, executed by the parties to be +bound thereby. This Agreement shall bind and inure to the benefit +of Id Software, its successors and assigns, and Id Software may +assign its rights hereunder, in Id Software's sole discretion. +This Agreement is personal to Licensee, and Licensee shall not +sublicense, assign, transfer, convey nor franchise its rights +granted hereunder. + + 19. CHOICE OF LAW, VENUE AND SERVICE OF PROCESS. This +Agreement shall be construed in accordance with the laws of the +State of Texas and applicable U.S. federal law and all claims +and/or lawsuits in connection with this Agreement must be brought +in Dallas County, Texas. Licensee hereby agrees that service of +process by certified mail to the address set forth below, with +return receipt requested, shall constitute valid service of process +upon Licensee. If for any reason Licensee has moved or cannot be +validly served, then Licensee appoints the Secretary of State of +the state of Texas to accept service of process on Licensee's +behalf. + + 20. EXCUSED PERFORMANCE. Neither party shall be deemed +to be in default of any provision of this Agreement nor be liable +for any delay, failure in performance or interruption of service, +resulting directly or indirectly from acts of God, civil or +military authority, civil disturbance, military action, war, +strikes, other catastrophes or any other similar cause beyond its +reasonable control. Written notice to the non-affected party of any +such condition shall be given by the affected party within ten (10) +days of the event. + + 21. DELIVERY OF NOTICES, AND DELIVERY OF PAYMENTS. +Unless otherwise directed in writing by the parties, all notices +given hereunder and all payments made hereunder shall be sent to +the addresses set forth on the signature page hereof. All +notices, requests, consents and other communications under this +Agreement shall be in writing and shall be deemed to have been +delivered on the date personally delivered or on the date deposited +in the United States Postal Service, postage prepaid, by certified +mail, return receipt requested, or telegraphed and confirmed, or +delivered by electronic facsimile and confirmed.

Wade Cloud, Jr., +Hiersche, Martens, Hayward, Drakeley & Urbach, P.C., 15303 Dallas +Parkway, Suite 700, LB 17, Dallas, Texas 75248. + + 22. NO PARTNERSHIP, ETC. This Agreement does not +constitute and shall not be construed as constituting a partnership +or joint venture between Id Software and Licensee. Neither party +shall have any right to obligate or bind the other party in any +manner whatsoever, and nothing herein contained shall give, or is +intended to give, any rights of any kind to any third persons. + + 23. COUNTERPARTS. This Agreement may be executed in +several counterparts, each of which will be deemed to be an +original, and each of which alone and all of which together, shall +constitute one and the same instrument, but in making proof of this +Agreement it shall not be necessary to produce or account for each +copy of any counterpart other than the counterpart signed by the +party against whom this Agreement is to be enforced. This +Agreement may be transmitted by facsimile, and it is the intent of +the parties for the facsimile of any autograph printed by a +receiving facsimile machine to be an original signature and for the +facsimile and any complete photocopy of the Agreement to be deemed +an original counterpart. + + 24. MEDIATION. If a dispute arises out of or relates to +this Agreement, or a breach of this Agreement, and if the dispute +cannot be settled through direct discussion, then the parties agree +to endeavor to settle the dispute in an amicable manner by +mediation, under the applicable provisions of Section 154.00 et +seq., Texas Civil Practices and Remedies Code, as supplemented by +the rules of the Association of Attorney Mediators. + + 25. SURVIVAL. The following provisions shall survive +the expiration or earlier termination of this Agreement: +paragraphs 4., 7., 8., and the audit rights of Id Software in +paragraph 12.c. + + 26. MISCELLANEOUS. + + a. All captions in this Agreement are intended solely +for the convenience of the parties, and none shall effect the +meaning or construction of any provision. + + b. The terms and conditions of this Agreement have been +negotiated fully and freely among the parties. Accordingly, the +preparation of this Agreement by counsel for a given party will not +be material to the construction hereof, and the terms of this +Agreement shall not be strictly construed against such party. + + By signing in the spaces provided below, the parties have +agreed to all of the terms and conditions set forth in this +Agreement. + + +AGREED: + +LICENSEE: + + +Signed:_______________________________ +Printed Name:_________________________ +Title:________________________________ +Address:______________________________ +______________________________________ +______________________________________ +Telephone #: _________________________ +Fax #:________________________________ +E-Mail Address:_______________________ +Date: ________________________________ + + +AGREED: + +ID SOFTWARE, INC. + + +Signed:_______________________________ +Printed Name:_________________________ +Title:________________________________ +Address:______________________________ +______________________________________ +______________________________________ +Telephone #: _________________________ +Fax #:________________________________ +E-Mail Address:_______________________ +Date: ________________________________ + + + +June 10, 1996 + + + +COMMERCIAL EXPLOITATION LICENSE AGREEMENT FOR QUAKE +(DWC:dw:3406.0299:dwc\doc:5017) + + diff --git a/contrib/other/sdlquake-1.0.9/data/HELP.TXT b/contrib/other/sdlquake-1.0.9/data/HELP.TXT new file mode 100644 index 000000000..ef79fbdcf --- /dev/null +++ b/contrib/other/sdlquake-1.0.9/data/HELP.TXT @@ -0,0 +1,119 @@ +TECH SUPPORT +Any of the information listed below could change.

Background + You get the phone call at 4 a.m. By 5:30 you're in the secret + installation. The commander explains tersely, "It's about the Slipgate + device. Once we perfect these, we'll be able to use them to transport + people and cargo from one place to another instantly. + + "An enemy codenamed Quake, is using his own slipgates to insert death + squads inside our bases to kill, steal, and kidnap.. + + "The hell of it is we have no idea where he's from. Our top scientists + think Quake's not from Earth, but another dimension. They say Quake's + preparing to unleash his real army, whatever that is. + + "You're our best man. This is Operation Counterstrike and you're in + charge. Find Quake, and stop him ... or it ... You have full authority + to requisition anything you need. If the eggheads are right, all our + lives are expendable.." + +B. Prelude to Destruction + While scouting the neighborhood, you hear shots back at the base Damn, + that Quake bastard works fast! He heard about Operation Counterstrike, + and hit first. Racing back, you see the place is overrun. You are almost + certainly the only survivor. Operation Counterstrike is over. Except for + you. + + You know that the heart of the installation holds a slipgate. + Since Quake's killers came through, it is still set to his dimension. + You can use it to get loose in his hometown. Maybe you can get to the + asshole personally. You pump a round into your shotgun, and get moving. + +II. INSTALLING QUAKE +A. Installation + You must install Quake before you can play it. It will not run off the + CD-ROM. Place the CD-ROM into your drive, log on to that drive, and type + 'INSTALL'. If you have downloaded Quake via modem, simply go to the + directory you've placed Quake in, unzip it, and type 'INSTALL'. + +B. README.TXT + After you install Quake, you go right into the README.TXT file, which is + henceforth available in your Quake directory. This is a full listing of + Quake's technical parameters, and is constantly updated with new versions + of Quake. We strongly recommend that after you install Quake, you glance + through README.TXT. + + You may wish to print this file out, so you can have a copy of it on hand + while playing Quake. + +C. MANUAL.TXT + Also available in your Quake directory is a file labeled MANUAL.TXT. + This is the file you are now reading. + +D. TECHINFO.TXT + For those who are more technically inclined, or to fill out a bug report, + check out TECHINFO.TXT. Information on filling out a bug report is located + at the end of TECHINFO.TXT. + + +III. THE BASICS OF PLAY +A. Goal of the Game + Quake has two basic goals. First, stay alive. Second, get out of the + place you're in. The first level of each episode ends in a slipgate -- + these signify that +you're entering another dimension. When you complete + an entire +dimension (this takes six to eight levels), you'll find a + Rune and another slipgate, which returns you to the start. + +B. Skill + The start area has three short hallways. The one you go down selects + the Skill you wish to play at. + Easy -- This is meant for little kids and grandmas. + Medium -- Most people should start Quake at Medium skill. + Hard -- Here at id, we play Hard skill, and we think you should too, + once you're ready. + (Nightmare) -- This is so bad that the entry is hidden, so people + won't wander in by accident. If you find it, don't say we didn't warn + you. + +C. Episode + After the Skill halls, you're in a room with four exits. Each exit + leads to a different military complex, at the end of which is a + slipgate leading to a new dimension. If you have not registered, the + first episode, Dimension of the Doomed, is the only place you can go. + After registration, all four episodes are available. The other three + episodes, in order from second to fourth, are Realm of Black Magic, + Netherworld, and The Elder World. + +============================================================================= +== TIP -- From episode 1 to episode 4, the dimensions become progressively == +== more difficult. We suggest you play the episodes in the proper order to == +== get the maximum fun out of Quake. == +============================================================================= + +D. Getting About + The specific keys named below can be changed by using the Configure Keys + Menu. If you have renamed Run as the R key, for instance, then the Shift + key will not double your speed. + Walk + Use the arrow keys or the mouse. To walk steadily forward, hold down + the Forward key (up arrow or center mouse button). Turn left or right + with the left or right arrow keys or sliding your mouse to the left or + right. + Run + Hold down Run (the Shift key) to double your speed. + Jumping + Tap the Jump key (the space bar or Enter key). You jump further if + you're moving forward, and you jump higher if you're moving up a slope at + the time. You'll be surprised at the spots you can reach in a jump. You + can even avoid some attacks by jumping at the right time. + Swimming + When underwater, aim yourself in the direction you wish to go, and + move forward. You have full three-dimensional freedom. Unfortunately, + as in real life, you may lose your bearings while underwater. Use + jump (the space bar or Enter key) to kick straight up towards the + surface. Once on the surface, tread water by holding down jump. + To get out of the drink, swim towards the shore. Once there, use jump + to clamber up. If you're down a well or you can't get a grip, you may + not be able to climb out. There is always another way out, but you may + have to submerge to find it. + Shooting + Tap the Shoot key (the Ctrl key or left mousebutton) to fire. Hold it + down to +keep firing. + Use + Quake has no "Use" function. To push a button or open a door, walk up + to it. To ride a platform up or down, step atop it. If a door won't open + or a platform won't lower, you may need to do something special to + activate it. + Picking up stuff + To pick up items, weapons, and power-ups, walk over them. If you can't + pick up something, it means you already have the maximum possible of + that thing. If it is armor, it means the stuff you're trying to get is + worse than what you now have. + +E. Finding Things + Buttons and Floorplates + Buttons activate with a touch, and floorplates must be stepped on. + If you see a distinctive-looking button in a spot you cannot reach, + it's probably a shootable button-- fire at it. + Doors + Most doors open at your approach. If one doesn't, seek a button, + floorplate, or key. + Secret Doors + Some doors are camouflaged. Almost all secret doors open when they are + shot or hit with an axe. The rest are opened by hidden pressure plates + or buttons. + Platforms + Most platforms only go up and down, while some follow tracks around + rooms or levels. When you step atop of a platform, it rises to its + full height, and usually only lowers when you step off. Some platforms + must be activated via button or pressure plate. + Pressure Plates & Motion Detectors + Invisible or visible sensors which open doors, unleash traps, warn + monsters, etc. + Uncovering Secrets + Secrets are hidden lots of ways. You might need to shoot a button, kill + a monster, walk through a secret motion detector, etc. + The Secret of Secrets + All secrets in Quake are indicated by clues. Don't waste your time + hacking at every wall. It's much more productive (and fun) to use your + brain and your eyes. Look up. An angled texture, a light shining under + a wall, a strange sound -- anything -- might be the clue. Something + prominent in a room might be decoration ... or it might be the clue. + +============================================================================= +== TIP -- Bouncing a grenade off a shootable button or secret door won't == +== open it, but if the grenade's explosion goes off nearby, this may == +== activate such secrets. == +============================================================================= + +IV. CONTROLS +A. Keyboard Commands + By using the key configuration option from the Main Menu, you can + customize the keyboard to suit your fancy, except for the Function keys, + the Escape key, and the ~ (tilde) key. + +FUNCTION KEYS +Help F1 +Save Game F2 +Load Game F3 +Options Menu F4 +Multiplayer Menu F5 +Quicksave F6 +Quickload F9 +Quit to operating system F10 +Screenshot F12 + +WEAPONS +Axe 1 +Shotgun 2 +Double Barrelled Shotgun 3 +Nailgun 4 +Supernailgun 5 +Grenade Launcher 6 +Rocket Launcher 7 +Thunderbolt 8 +Change to next weapon / + +MOVEMENT +Move / Turn arrow keys +Jump / Swim Space bar or Enter +Run Shift +Sidestep Left . or > +Sidestep Right , or < +Strafe * Alt +Swim Up D +Swim Down C + +OTHER CONTROLS +Main Menu Escape +Console ~ (tilde) +Look Up A or PgDn +Look Down Z or Del +Center View X or End +Mouse Look ** \ or center mouse button +Keyboard Look *** Ins + + * Turning right or left sidesteps instead while the Strafe key is pressed. + ** Sliding your mouse forward and back looks up and down while the Mouse + Look key is pressed. +*** The walk forward/backpedal arrows will look up and down while the + Keyboard Look key is pressed. + +B. The Main Menu + Tap the Escape key to pop up the Main Menu. While you are in the menu, + the game is paused. + Use the arrow keys to move the Quake icon up and down the menu. Place + the icon before the desired option, and tap the Enter key. To return to the + Main Menu, tap the Escape key again. To exit the menu and return to the + game, tap the Escape key when you are on the Main Menu. + + NEW GAME + Discards the game you're playing, and starts anew. + + MULTIPLAYER + Controls multiplayer game starting and details... + Name + Type your name or alias here, and all messages about you will use + this. So the computer says stuff like, "Josephine rides Bad Bill's + rocket." + Shirt Color + Lets you select your character's uniform color from 14 different + options (numbered 0-13). + Pants Color + As above, but your pants color also determines what team you're on, + if in team play. (After all, pants are more important than shirts.) + Communications Configuration + Takes you to a separate menu on which you can change communications + settings. + Com Port + Selects the COM Port to use for Communications. A null modem or + modem must be connected to this port. + Baud Rate + Selects the COM port baud rate (9600-57600bps). This is NOT the + same as setting the modem speed. The COM port speed must be AT + LEAST the same speed as the modem speed. + Device + Selects the type of connection, either direct (null-modem) or + modem. + Modem Init String + The Initialization string for the modem. + + Start a Multiplayer Game + If you want your machine to be the host for a multiplayer game + (Note: if you are starting a listen server, id Software strongly + recommends that the fastest machine act as the host! If you are + playing a game with more than 4 players, we suggest using a + dedicated server as the host!), select this option, and you'll get + the following menu ... + Begin Game + Starts up the game. Now all your friends have to do is log on, + using either "search for local network games" or "join a + running game at..." Multiplayer options (see below). + Maximum Players + You can have up to 16 players. You need at least 2, or it's not + "multiplayer", right? + Game Type + Toggles between cooperative and deathmatch. + Team Color Rules + Toggles between "none" and "no friendly fire". In the latter mode, + your shots won't injure someone wearing the exact same color + pants as you. + Skill + Chooses skill level. Only applicable in a cooperative game. + Frag Limit + From none to 100, in ten-frag increments. When someone reaches + the frag limit, by killing the 40th (or whatever) person, then + the game ends immediately, and final scores are printed. If your + frag limit is none, the game won't end till someone exits the + level or the time limit expires. + Time Limit + From none to 60 minutes, in 10 minute increments. When the time + limit is up, the game ends immediately, and final scores are + printed. If your time limit is none, the game won't end till + someone exits the level or the frag limit is reached. + Start Map + Lets you choose what map you'd like to play on. The top line + gives you the episode name, and the lower line is the level's + name. Note that all levels in Quake are fun to play, but the + episode Deathmatch Arena is composed of special levels that are + solely-designed for deathmatch play. Try them, you'll like them. + Search For Local Network Games + Has your computer look through your network. It will list all the + games it finds on the console, and you can choose to join one of + them by typing connect . + Join A Running Game At ... + Lets you join a game either by typing its net address (for a net + game) or your friend's modem phone number (for a modem game). + If necessary, ensure your modem and network connections are operative + by checking your Communications Configuration menu. + + SAVE + Brings up a list of saved games. Highlight the desired slot, and tap the + Enter key. Each saved game is identified by the level's name, plus the + proportion of kills you have achieved so far. + LOAD + Brings up a list of saved games. Highlight the desired slot, and tap the + Enter key. + OPTIONS + Miscellaneous game options ... + Configure Keys + Permits you to customize Quake so every action is linked to the + button or key that you prefer. + First, move the cursor (via the arrow keys) to the action you + wish to change. Then tap the Enter key. Now press the key or + button you want to bind to that action. For instance, if you wish + to use the Alt key for Jump, move the cursor to Jump / Swim, tap + the Enter key, then press the Alt key. + Each action can have two different keys assigned to it. If you + already have two keys in an entry, you cannot add more from this + menu. + To clear the keys bound to an action, move the cursor to that + action and tap the Backspace or Delete key instead of the Enter + key. This will clear the keys formerly bound to that action, + leaving it blank. + You can bind any key to an action except Function keys, the + Escape key, and the ~ (tilde) key. "Weird" keys such as Scroll + Lock, Print Screen, etc. may or may not work, depending on your + machine, but why bother? + + Attack + Fires your weapon + Change Weapon + Switches to the weapon "above" the one you're now using. Wraps + around to the axe. + Jump / Swim Up + If you're on land, jumps. If you're underwater, kicks you + towards the surface. If you're right at the water's edge, pops + you up out of the water, if you combine it with forward + movement. + Walk Forward + Backpedal + Turn Left + Turn Right + Run + Press this while moving, and you move at double speed. + Step Left + Sidesteps (strafes) left + Step Right + Sidesteps (strafes) right + Sidestep + Press this when using turn left or turn right and you sidestep + (strafe) instead. + Look Up + Lets you angle your view upwards. Your view returns to + horizontal when you start walking forward. + Look Down + Lets you angle your view upwards. Your view returns to + horizontal when you start walking forward. + Center View + If you're looking up or down, returns your view to dead + center. + Mouse Look + Press this to allow your mouse to look up or down (by + sliding it forward and back), and to remain looking up or + down even if you move forward. + Keyboard Look + Press this to use your movement keys to look up or down. + Go To Console + Brings down the Console. Also possible by tapping the + ~ (tilde) key. + Reset To Defaults + Everything you've changed in the options menu is reset by + this option. Consider it an "Oops" key. + Screen Size + A slider which enlarges or shrinks your view area. All + Quake's sliders use the right and left arrow keys. + Brightness + Pretty much self-explanatory. Choose a brightness which + doesn't strain your eyes. + Mouse Speed + Adjusts mouse sensitivity. The further you set the slider + to the right, the quicker your mouse reacts. + Music Volume + Self-explanatory + Sound Effects Volume + Self-explanatory + Always Run + When this is selected, you do not need the Run key -- you + are always at double speed. + Invert Mouse Up / Down + This gives your mouse "airplane-style" controls. This means + that pushing the mouse forward "noses down", and pulling it + back "noses up". Some people prefer this control technique. + Lookspring + Returns your view immediately to straight ahead when you + release the look up / down key. Otherwise, you must move + forward for a step or two before your view snaps back. + Lookspring does not work while you are underwater. + Lookstrafe + If you are using the look up / down key, then this option + causes you to sidestep instead of turn when you try to move + left or right. + + HELP / ORDERING + Lists the default keyboard and mouse commands. Also contains the + information you need to register Quake. + QUIT + Exits Quake at once. + +============================================================================= +== TIP -- Quake saves your current key configuration when you quit, so == +== next time you play, you have the same configuration. == +============================================================================= + +C. Console + Tap the ~ (tilde) key to bring down the console. As with the Main Menu, + when the console is down, a singleplayer game is paused. A wide variety of + esoteric commands can be entered at the console. If your keyboard has no + ~ (tilde), the Options Menu (inside the Main Menu) has a "Console" option. + +D. Command Line + For special command line parameters, see README.TXT. + +E. Cheat Codes + id Software, as in our previous games, has removed all cheat codes from + Quake. + +V. THE GAME +A. The Screen + The large top part of the screen is the view area, in which you see + monsters and architecture. Immediately below is the Inventory, beneath + which is the Status Bar. You can enlarge the viewing area (tap the + key), + so much that it engulfs first the Inventory Bar and then the Status Bar. + The - key shrinks the view area. + + Inventory Bar + Lists ammo, weapons, deathmatch scores, and power-ups. + The active weapon is lit up. Each weapon has a number by it -- type + the appropriate number key to switch to that weapon. + In addition, this gives the amount of ammo you have of each type, + any keys you possess, and any power=ups currently active. Plus it shows + how many and which of the four Runes you possess. + In Deathmatch, it shows the top four scores in the game. + + Status Bar + A vital part of the screen. When your armor, hit points, or ammo get + low, the number turns red. + From left to right, the big numbers represent: Armor Points, Health, + and Ammo (of the current weapon). Icons show the Armor Type (green, + yellow, or red), your adorable face, and your Ammo Type). + + Score Bar + Hold down theTab key to replace the Status Bar with the Score Bar. + This lists the proportion of monsters you've killed, secrets you've + found, and time you've spent, along with the level name. + In Deathmatch, the Score bar lists the top six scorers, along with + their names. + +B. Messages + Quake talks to you from time to time. Some messages appear at the top of + the screen. These are non-critical, and tell you that you've picked up an + object, or you've died in an interesting fashion. Ignore these messages if + you please. + Certain messages appear inconveniently in the middle of your view. These + are always important, and you do not want to ignore them! + +D Ending a Level + Once you finish a level, you'll find a slipgate or a distinctive archway + leading to the next level. Pass through to emerge onto a new level. + You start the new level with the same armor, weapons, and ammo you had at + the end of the previous one. If a power-up was active at the end of the + previous level, it is now, sadly, gone. Make the best of it. If your hit + points were over 100 or under 50, they are altered to 100 or 50, + respectively. Otherwise, your hit points are unchanged. + +D. Ending a Dimension + Once you've finished all the levels in a particular dimension, you return + to the starting hall. New dimensions are started from scratch -- you, your + shotgun, and axe. + +VI. Your New Environment +A. Firepower + You are blessed with eight different Means o' Mass Destruction. Each has + its place in a balanced diet. + + Axe + The last resort. Face it -- going toe-to-toe with the uglies in Quake + demonstrates all the good sense of a man parachuting into an alligator + farm. + + Shotgun + The basic gun, to which all other guns compare favorably. + + Double-barrelled Shotgun + A worthy weapon with three minor drawbacks: first, it uses up 2 shells + per blast; second, it's slow; third, its shot pattern is very loose at + long range. But in general, once you find this puppy, the other shotgun + starts rusting from disuse. + + Nailgun + A two-barrel dingus that prickles bad guys with armor-piercing darts, + technically termed "nails". + + Supernailgun + The great equalizer. Four cyclic barrels that hose out spikes like + crazy. Pro: foes drop like flies. Con: eats ammo like popcorn. + + Grenade Launcher + Thumps neat exploding bombs into the air. You can even bounce a grenade + off the wall or floor.. When a grenade hits someone, it explodes. + If it misses, the bomb sits on the floor for a moment, then explodes. + Even though I sometimes bounce grenades into myself, this gun's still + my favorite. + + Rocket Launcher + For when a grenade positively, absolutely, has to be there on time. + + Thunderbolt + Try it. You'll like it. Use the same technique as watering your + rosebush. + + Switching Between Weapons + If you are firing a weapon and run out of ammo, Quake automatically + switches you to another weapon. It will never switch to the grenade + launcher or rocket launcher, however, for reasons that ought to be + obvious. So if you're firing away happily and suddenly switch to the + axe, it doesn't mean you're out of all ammo -- you may still have + grenades. But Quake requires you to select such dangerous + explosives on your own. + +============================================================================= +== TIP -- If you shoot the Thunderbolt underwater, it discharges all its == +== cells in every direction in a single gigantic KA-ZAP, with you at the == +== center. Don't try this at home. == +============================================================================= + +B. Ammo + The eight weapons use four types of ammo. Each ammo type comes in two + flavors -- small and large. The large boxes carry twice as much as the + small. + + Shells + For shotguns and double-barrelled shotguns. A small box holds 20. + + Flechettes + For nailguns and supernailgunss. A small box holds 25. + + Grenades + For grenade launchers and rocket launchers. A small crate holds 5. + + Cells + For Mr. Thunderbolt. A small battery has 6 charges, lasting a little + over a second. + +C. Power-ups + All power-ups except armor burn out after a while, so smoke 'em while you + got 'em. + + Armor + Comes in three flavors; green, yellow, and red, from weakest to most + powerful. + + Megahealth + Gives you 100 additional hit points. After a few seconds, all hit points + over 100 start slowing draining away, because it's too much for the human + frame to hold. Still, it's nice while it lasts. + + Biosuit + lets you breathe underwater and swim through slime without harm. Does + not protect against lava. + + Ring of Shadows + Renders you almost totally invisible. Only your eyes can be seen. + Monsters don't detect you unless you do something stupid. Like shoot. + + Pentagram of Protection + Renders you invulnerable. + + Quad Damage + Magnum upgrade! You now deliver four times the pain! + +============================================================================= +== TIP -- When quad damage is activated, use the grenade or rocket == +== launcher with care -- their bursts are four times as deadly to you, as == +== well as your enemies. == +============================================================================= + +D. Bad Guys + Quake critters are extremely tough, but you have the firepower to vent + your grievances on them anyway. Good hunting. + + Rottweiler + Bad, bad doggie! Play dead! -- blam! -- yipe! Good dog! + + Grunt + Goons with probes inserted into their pleasure centers; wired up so + when they kill someone, they get paroxysms of ecstasy. In essence, + customized serial killers. Easy to kill, and they tote shotgun shells. + It's like a little Christmas each time you blow a Grunt away! + + Enforcer (registered only) + Grunt, Mark Two. Recruits who are surlier and beefier than the rest get + outfitted in combat armor and built-in blasters. + + Knight + Canned meat. Open 'er up and see if it's still fresh. + + Death Knight (registered only) + This particular canned meat tends to open you up instead. + + Rotfish (registered only) + Disgusting little critters who dish it out, but can't take it. + + Zombie + Thou canst not kill that which doth not live. But you can blast it + into chunky kibbles. + + Scrag + Floats like a butterfly, stings like a bee. Ugly as hell. They're not + real tough, but like to bushwhack you. + + Ogre + What's worse than a cannibal monster eight feet tall? One with a + chainsaw. And a sack of grenades. + + Spawn (registered) + A merrily bouncing blob as dangerous to kill as to ignore. Blech. + + Fiend + In essence, organic buzzsaws, rife with pummeling power! + + Vore (registered) + A spideresque hybrid horror. Keep your eye on the energy pod he hurls. + + Shambler + Even other monsters fear him, so expect a clobbering. He shrugs off + explosions. Good luck. + +============================================================================= +== TIP -- Some weapons are better vs. particular monsters than others. If == +== a new monster seems real tough, switch weapons. == +============================================================================= + +E. Environmental Hazards and Effects + + Explosions + Radioactive containers are in some military bases. Shooting these + things unleashes a big boom, so be careful -- you may not want to + stand too close in a firefight. + Your own grenades and rockets cause explosions too, of course -- the + blast can hurt you if you're too close. + + Water + Safe enough unless you stay under so long you start to drown. Come up + for air periodically to prevent this. + + Slime + Hurts you instantly and keeps on hurting. Stay out of slime unless you + have a very good reason to take a dip. + + Lava + If you're quick and the lava's shallow, you might escape before you're + burnt to a crisp, but don't bet on it. + + Traps + Quake has many different traps. Don't be paranoid, because traps aren't + really very common, but be aware of their existence. Traps can't be + classified because they come in many varieties -- monsters in ambush, + spike shooters, crushing walls, trapdoors, etc. + + Teleporters + These are distinctive in appearance and emit a unique sound. When you + step into a teleporter, you're instantly transported to another + teleporter, or atop a teleport pad. If you teleport directly right atop + of somebody else, he or she is killed instantly. + +============================================================================= +== TIP -- Monsters are smart enough not to activate their own traps, but == +== if you activate the traps, the monsters can get caught by them. == +============================================================================= + +VII. Multiplayer Action + Quake can be even more fun when you're playing with friends than when + you're playing by yourself. + When you are using the console or Main Menu in multiplayer, the game does + not pause. Irresponsible players and monsters can freely shoot you, and + your only recourse is bloodthirsty vengeance. + The Talk function is useful here. When you talk, the message appears at + the top of all players' screens, preceded by the speaker's name. + To talk, press 'T' and start typing your message. Press ENTER to set + the message to everyone. + To set up, run, or join a multiplayer game, use the Main Menu Multiplayer + option. README.TXT contains details that may be useful if your network or + modem need special configurations. + +A. Cooperative + In a co-op game, you and your friends work together to finish the level. + When one person exits, everyone else exits too, wherever they might be. If + you are killed in co-op, you reappear at the start area, and have to catch + up to your buddies. Use Talk to find out where they are. See the + Multiplayer options on the Main Menu for more info. + +B. Deathmatch + In a deathmatch, play is totally cutthroat. No monsters exist, and when + you are killed, you reappear in a random spot. After you pick up an item, + it respawns (i.e. pops back into existence) after a while. (Some items + take longer to respawn than others.) Every time you kill someone, you get + a Frag. The person with the most Frags wins, so wreak slaughter amongst + your pals! + If you kill yourself, whether intentionally or by accident, you lose a + Frag. This includes drowning, getting crushed, and so forth. See the + Multiplayer options on the Main Menu for more info. + +C. Team Games + Team play is a cool combination of co-op and deathmatch. Each team picks + a "uniform" and everyone on that team changes their color to the team + color. The team with the most Frags wins. See README.TXT or the Main Menu + for details. + +============================================================================= +== TIP -- if you have the Team Color Rules set to No Friendly Fire, your == +== weapons won't hurt other players wearing the same color pants as you. == +== (You can still have differently-colored shirts.) Your shots still wear == +== down their armor, and your own grenade and rocket explosions still hurt == +== YOU, just not them. == +============================================================================= + +VIII. Commonly Asked Questions + +Q. I'm stuck. How do I get through the level? +A. Take a stroll around and look for a place you haven't been yet. Sometimes +you have to kill a particular monster in order to progress, so exterminate +them all! + +Q. How can I find all the secrets? +A. Don't worry about it. You never have to find a secret to finish a level.. +Also, some secrets are intentionally hard to find. + +Q. I've cleared out the whole level, but my monster kill score isn't 100%. +Where are they hiding? +A. Some monsters hide inside secrets, or are released by them. You won't be +able to kill those monsters until you find their secrets. Also, some monsters +might lurk underwater. Good fishing. + +Q. Don't you worry that Quake teaches people that all problems can be solved +by the misuse of deadly force? +A. No. + +Q. Did I really see two monsters fighting each other? +A. Probably. Some monsters hate one another almost as much as they hate you. +You can use this to your advantage (exercise left up to the reader). + +Q. How do I prevent motion sickness when watching Quake? +A. If you're one of the unlucky sufferers from motion sickness in Quake, +we're sorry to say the answer seems to differs from person to person. Try +sitting closer to the screen, or further away. Dim the lights in your room, +or turn them up high. Adjust screen brightness up or down. Take a break from +Quake and rest your eyes every hour or so. One or more of these tricks, or a +combination, ought to work. + +Q. Are you guys Satan-worshipers? +A. No. + +IX. Tech Support + Any of the information listed below could change.

Workarounds include: + +1) If running from Windows, start Quake from an icon, or from a windowed +(not fullscreen) MS-DOS prompt. If Quake is already running and has +the garbled screen, press Alt-Enter twice to switch to the desktop and +back to fullscreen, and the screen will display properly. + +2) If running from DOS, either put the line + +vid_mode 1 + +in id1\autoexec.cfg, or, typing blind, press tilde ('~') to bring down +the console, type + +vid_mode 1 + +and the screen will display properly. + +======================================================================== +Here are the text files included with the shareware release of Quake and +what they are: + +README.TXT This file +TECHINFO.TXT Technical information on Quake's subsystems and + their advanced use. +MANUAL.TXT Text version of the printed game manual +LICINFO.TXT Info on the various license files included with Quake +SLICNSE.TXT Shareware Quake end-user license +ORDER.TXT How to order Quake +HELP.TXT How to get help with Quake + +Here are the text files included with the registered version of Quake and +what they are: + +README.TXT This file +TECHINFO.TXT Technical information on Quake's subsystems and + their advanced use. +MANUAL.TXT Text version of the printed game manual +LICINFO.TXT Info on the various license files included with Quake +RLICNSE.TXT Registered Quake end-user license +COMEXP.TXT Commercial exploitation agreement +ORDER.TXT How to order Quake +HELP.TXT How to get help with Quake + + +Running Quake +------------- + +DOS: To launch Quake from the DOS Prompt, go to the Quake directory and +simply type "QUAKE" . (no quotes) + +Windows 95: To launch Quake in single player mode, double click on the file +QUAKE.EXE From Windows Explorer. To run Quake in Multi-Player mode using +the TCP/IP protocol, first check your network settings to ensure the +protocol is installed, then double click on the Q95.BAT file to launch the +game. In this version (v0.91) there is a minor bug that will cause the +Q95.BAT file to exit the first time you run it, without running Quake. +Merely double-click on that file again and it will work. + +Audio Setup +----------- + +When using a Sound Card with Quake, there are a few setup steps which must +be taken. First, the "BLASTER" environment variable setting must be in your +autoexec.bat (or you can type it in manually from the MS-DOS command prompt). +Running the Sound Blaster utility diagnose.exe will automatically configure +your sound card and put this statement in your autoexec.bat file for you. +A typical blaster setting looks like this (although yours may vary): + +SET BLASTER=A220 I5 D1 H5 P330 T6 + +If you want to play the audio track from the CD-ROM while playing Quake, +you must ensure that the audio cable from the CD-ROM is connected to the +sound card. + +If you think your sound card is setup properly and it STILL doesn't work, +check to make sure that your BLASTER environment variable contains the +high DMA setting (H5 in the above example). + +If you don't get sound while trying to play the audio track, check to see +if a small cable goes from the back of your CD-ROM player directly to your +sound card. If the CD-ROM audio cable is connected to your sound board (or +the motherboard in some cases) and you STILL don't hear CD Audio coming from +your speakers, make sure the MIXER program has the CD volume turned up. +You will also need to run the CD-ROM driver MSCDEX.EXE. Here is an example +of the files you should see (yours probably will vary) listed in your +CONFIG.SYS and AUTOEXEC.BAT (explanation is in parentheses): + +CONFIG.SYS: + +DEVICE=C:\PROSCSI\CDROM.SYS /D:PROCD01 (CD-ROM driver) + +AUTOEXEC.BAT: + +SET BLASTER=A220 I5 D1 H5 P330 T6 (sound environment variable setting) +C:\WINDOWS\COMMAND\MSCDEX.EXE /D:PROCD01 /L:D (CD-ROM driver) + +=================================================== +UltraSound MAX and UltraSound PnP Support for Quake +=================================================== + +Before running Quake, make sure that your sound card works and your +environment variables are set correctly. + +Other UltraSound Cards (ACE & Classic) +-------------------------------------- +These drivers are not for the UltraSound ACE or UltraSound Classic +sound cards. We have heard mixed reports that MegaEm or SBOS +have a chance of working with the UltraSound Classic but there is a +short sound F/X delay. + +UltraSound PnP and PnP Pro +-------------------------- +You must make sure that you do NOT have IWSBOS or MegaEm loaded. + +Setup +----- +Quake will automatically detect that the UltraSound Max or PnP +are installed. It does this by looking at the SET INTERWAVE (PnP) +and SET ULTRA16 (Max) environment variables. + +Quake will use the settings found on the SET ULTRASND/ULTRA16 (Max) +and in the IW.INI (PnP) file to determine what port settings to use. + +Troubleshooting Windows 95 (DOS Box) +------------------------------------ +We recommend that you restart your computer in MS-DOS Mode. DOS Box +may or may not work, so use at your own risk. + +CD Audio Input +-------------- +If you have not already enabled CD audio output by default you will +need to enable it. For the UltraSound MAX you can run "ULTRINIT -EC". +For the UltraSound PnP you will need to enable the CD audio output +in Win'95 and then restart your computer into MS-DOS. + +=================================================== +Mouse Setup +----------- + +If you are going to use a mouse when playing Quake, you will need to load +your mouse driver. This should go in the AUTOEXEC.BAT file as well. Here +is an example: + +C:\LOGITECH\MOUSE\MOUSE.EXE (mouse driver) + + +Booting Clean +------------- + +If you are going to be running Quake with only 8 megabytes of RAM, it is best +to boot clean . You eliminate unwanted utilities or applications from taking +up valuable memory, without having to alter your regular AUTOEXEC.BAT and +CONFIG.SYS. Booting clean can be done in one of two ways. If you have +MS-DOS version 6.xx, booting clean is as simple a pressing the shift key +when you see the words "Starting MS-DOS". If you have MS-DOS ver 5.xx you +will need to make a system disk. + +To make a boot disk, type the following from the MS-DOS command prompt: + +FORMAT A: /S + +1. Make sure that this is a disk you wish to erase. +2. This disk absolutely HAS to be formatted in the A: drive. + +To use the system disk, place the disk in the A: drive and reset the +computer. + +NOTE: If your sound card requires a driver to be loaded, or you will be +using a mouse, or you will be using Quake's CD audio feature, the system +disk will need to have a CONFIG.SYS and AUTOEXEC.BAT that load the +appropriate drivers. + +Creating a Quake Shortcut + +As an alternative to making a Boot Disk, Windows 95 users can create a +Quake Shortcut. By double clicking onthis shortcut, Windows 95 will reboot +in MS-DOS mode and install only the desired drivers, giving you the same +results as using a Boot Disk. To create a Quake Shortcut, do the following: + +1. Using Explorer, right click and drag the file QUAKE.EXE, from the Quake + directory, to your desktop. Windows 95 will make an MS-DOS Icon titled + "Shortcut to quake". +2. Right click on the new icon, and from the menu that pops up, choose + "Properties". Then choose the "Program" tab at the top. +3. Now click on the "Advanced..." button near the bottom. The "Advanced + Program Settings" window should appear. +4. Select the "MS-DOS mode" check box and the "Specify a new MS-DOS + configuration" option button. +5. Now simply fill in the "CONFIG.SYS for MS-DOS mode:" and "AUTOEXEC.BAT + for MS-DOS mode:" boxes with the same sound, CD-ROM and mouse settings as + mentioned above in the Boot Disks section. +6. Click on "OK" when you are finished. If you wish, you can change your + Quake Shortcut Icon to something a little more exciting by clicking on + "Change Icon...". +7. To finish, click on "OK" again. + 8. You can rename your Quake Shortcut by right clicking on the shortcut + icon, choosing "Rename" and typing in the new name. + + +====================================================== +== Known Problems == +====================================================== + +Problem: Zombies sometime get stuck on the ground and connot get back up. +(You can still hear them, but you cannot kill them. This bug makes it +impossible to get 100% kills on whatever level it occurs on.) +Solution: There is no workaround for this bug. + +Problem: It is sometimes possible for the player to get stuck in a room or +in a wall. +Solution: If you get stuck, use the 'kill' console command. It is a good +idea to save your game often. + +Problem: View centering problems. Sometimes during a game, the view will not +center properly. The end result is the player view looking up torwards the +ceiling while walking. +Solution: Exit to the next level or use the 'kill' console command.. + + +====================================================== +== Troubleshooting == +====================================================== + +If Quake fails to start up, or has problems not addressed elsewhere in the +documentation, try the -safe command line switch, which disables a number +of parts of Quake that can be problems if there are hardware or configuration +problems. The -safe command line switch is equivalent to -stdvid, -nosound, +-nonet, and -nocdaudio together. Those four switches do the following: + +-stdvid: disables VESA video modes. + +-nosound: disables sound card support. + +-nonet: disables network card support. + +-nocdaudio: disables CD audio support. + +If -safe makes the problem go away, try using each of the switches +individually to isolate the area in which you're experiencing the problem, +then either correct the configuration or hardware problem or play Quake with +that functionality disabled. + +If you still have problems, try booting clean in conjunction with +the -safe command line parameter. For information on booting clean, refer +to the "Booting Clean" section above. + +If you experience page faults while running Quarterdeck's QDPMI DPMI server, +this is caused by a bug in QDPMI. Workarounds: Remove QDPMI from CONFIG.SYS, +issue the command QDPMI OFF before running QUAKE, or get the update patch +for QDPMI from Quarterdeck. You may be running QDPMI without knowing it if +you have QEMM installed, because it can be installed as part of the QEMM +installation. + + +Technical Support +----------------- + +If you are having trouble installing or running Quake you can receive +technical support by sending e-mailing to support@idsoftware.com.

To bring up the console, press the tilde ('~') +key or press ESC to bring up the menu, select Options, and select Console... +from the options menu. To exit the console, press ESC. + +The console provides a way to change console variables and also accepts +commands that change game settings such as movement keys, video mode, as +well as providing an interface for key binding and command aliasing (more +on that later). + +The console also has a command history with which you can browse through +previous commands. Use the up and down arrows to navigate through the +command history and press to re-issue a command. + +Partially typing a command and then pressing the TAB key will complete the +currently typed text with the first matching console variable or command. +(Yes, this is a good way to look for console commands.) + +To review previous actions by page, use the PGUP and PGDN keys. + + +========================================== +== Video Subsystem Documentation == +========================================== + +The Video Modes menu +-------------------- + +Video modes can most easily be selected from the the Video Modes menu, which +is brought up by selecting the Video Options choice in the Options menu. +All the resolutions that Quake can support on the current computer are +displayed. + +Please note that higher-resolution modes require correspondingly more +system memory in order for Quake to run, and that some high-resolution +modes may not be available when running Quake on 8 Mb machines. Such +modes are not listed in the Video Modes menu. Please do not report +video modes that do not appear in the Video Modes menu as bugs; either +those modes are not supported by your video adapter, or there is not +enough system memory for Quake to support those modes. + +The video modes listed in the Video Modes menu can be tested, set, and made +the default mode for Quake from the Video menu, as follows: + +* The arrow keys can be used to move the blinking indicator to any of the +modes listed in the Video menu. + +* Pressing the 'T' key tests the mode the blinking indicator points to, by +setting the mode, leaving it set for 5 seconds, and returning to the previous +mode. This lets you verify that your computer does in fact support that +mode. We highly recommend that you always test modes with 'T' before setting +them +permanently by pressing the Enter key, in case some sort of hardware or +software glitch causes a mode to function incorrectly and produce a garbled +screen. It is unlikely but possible that testing or setting a mode will +cause your computer to hang or crash; if this happens, there is a serious +hardware or software bug, and you should not attempt to select that mode +again. + +* Pressing the Enter key sets the mode the blinking indicator points to, +leaving it set so Quake will then run in that mode. We suggest that you +test a mode by pressing the 'T' key before setting it by pressing the Enter +key. Note that a selection made with the Enter key remains in effect only +until Quake is exited (or a new mode is set). You must explictly make a mode +the default mode by pressing the 'D' key in order to automatically set that +mode when you start Quake up in the future. + +* Pressing the 'D' key makes the current mode the default mode that Quake +starts up with. Note that the current mode is the mode that's displayed in +white in the mode list, not necessarily the mode that the blinking indicator +points to. The current default mode is listed in the description of the 'D' +key at the bottom of the Video Modes menu. + +* Pressing Esc exits the Video Modes menu. + +Please see "Bug Reporting," below, for information on how to report any +problems you encounter. + + +Video modes from the console: Quick start +------------------------------------------ + +More comprehensive but more complex video control is available through the +Quake console. This section describes the commands necessary to perform +basic mode setting through the console (this is similar to what can be +accomplished through the Video Modes menu), and following sections describe +console video control in detail. + +To see all the video modes that are available, bring up the console (either +press tilde ('~'), or press Esc to bring up the menu, select Options, and +select Console... from the Options menu). + +From the console, type vid_describemodes to see all available modes. +Type vid_mode to set a mode, where is the mode number +listed for the desired mode by vid_describemodes. Higher-resolution modes +generally require more extra system memory in order to run, and many are +not available in 8 Mb systems; modes that are supported by the video +adapter but are currently unavailable due to system memory limitations +will still show up in +the mode list from vid_describemodes, but will +have "**" in place of a mode number. (Such modes will not show up at +all in the Video Modes menu.) If you try to set a mode for which +there is insufficient system memory, you will receive a message to that +effect, and the video mode will remain unchanged. + + +More detail +----------- + +This version of Quake supports software drawing in a variety of +video modes. It does not support any 3-D hardware accelerators. +Video modes that are built into Quake are: + +320x200, 360x200, 320x240, 360x240, 320x350, 360x350, 320x400, +360x400, 320x480, 360x480 + +However, the higher-resolution modes on this list require additional +memory, and may not be available in 8 Mb systems. + +In addition, all VESA 2.0 256-color linear framebuffer modes +supported by the video adapter are supported. Further information +about VESA 2.0 is provided below. + + +Video mode reporting and selection +---------------------------------- + +Quake assigns each available video mode a mode number, which can +then be used to query information about the mode or to select the +mode. The first 11 mode numbers are always as follows: + +0: 320x200 +1: 320x200 +2: 360x200 +3: 320x240 +4: 360x240 +5: 320x350 +6: 360x350 +7: 320x400 +8: 360x400 +9: 320x480 +10: 360x480 + +You will notice that modes 0 and 1 are both 320x200; mode 1 is a +Mode X-style version, which may someday allow support of page +flipping for cleaner graphics, but right now it's just slower with +no advantages, so use mode 0 for 320x200 resolution. Modes 2-10 +are all higher resolution than mode 0, and look very nice, but are +also all slower than mode 0. Mode 0 is the fastest of the 11 +built-in modes. + +In addition to the built-in modes, Quake checks for the presence +of a VESA version 2.0 driver. If such a driver is detected, the +driver is queried for all 8-bit-per-pixel linear framebuffer (LFB) +modes that are supported; also, if no LFB 320x200 mode is available, +a banked 320x200 VESA mode is queried for. All such modes are added +to the mode list starting at mode 11. The available modes will vary +depending on adapter, graphics chipset, amount of video memory, and VESA +2.0 + driver. The higher the resolution, the lower the performance, and +the +higher-resolution modes will often be too slow for good gameplay +on most machines. (Also, higher-resolution modes often need more memory +than is available in an 8 Mb system.) The screen can be sized down to +improve performance in higher-resolution modes, but then of course the +effective resolution of Quake is reduced. + +At the same resolution, VESA LFB modes are often faster than the non-VESA +modes 0-10, because adapters often have faster memory access in LFB modes. + +If a given VESA mode can support page flipping, then it defaults to page- +flipped operation. A VESA mode can be forced to non-page-flipped operation +by setting the vid_nopageflip console variable to 1, then setting the mode + +(note that vid_nopageflip takes operation on the next, not the current, mode +set, and note that it then stays in effect permanently, even when Quake is +exited and restarted, unless it is manually set back to 0). If there is not +enough memory for two pages in a VESA mode, or if the +adapter doesn't support page flipping, then the mode will automatically +be non-page-flipped. Page flipping can have higher visual quality, but may +be either faster or slower, depending on the graphics adapter and other +hardware. (See the discussion of the Pentium Pro, below, for a +discussion of why page flipping can be faster but is sometimes much slower +on that processor.) Page-flipped modes use less system memory than non- +page-flipped modes. + +Quake's VESA support, including VESA driver detection, can be disabled by +using the -stdvid command-line switch, and can also be disabled, along with +sound, network, and other hardware support, by the -safe command-line switch. + +The maximum resolution supported by Quake is 1280x1024. Modes with higher +resolutions will not be reported by vid_describemodes, and cannot be set. + +There is no support for any 3-D accelerator boards in this version of Quake. +Coming soon. + +Quake always starts up in mode 0, and modes 0-10 are always available, given +enough system memory. + + +A note on modes reported in the Video Modes menu +------------------------------------------------ + +The vid_describemodes console command lists all modes with +resolution less than or equal to 1280x1024 that are +supported by the video adapter, although modes for which there +is not enough system memory have "**" for the mode number. VGA, +Mode X-style, and VESA 2.0 modes are listed separately, so a +single resolution can be listed as many as three times, once for +each hardware mode that supports it. For example, mode 0 is +VGA mode 0x13, which supports 320x200 resolution, and mode 1 is +320x200 Mode X-style mode. Quake looks identical in both +modes, although it usually runs faster in mode 0. + +The Video Modes menu is much simpler. Only modes with resolution +less than or equal to 1280x1024 that are both supported by the +hardware and for which there is sufficient system memory are +listed. Further, a given resolution is listed only once. If a +given resolution is available in multiple hardware modes, then +selecting that resolution will select the appropriate hardware mode +as follows: + +If the mode is 320x200, then VGA mode 0x13 is selected, and +equivalent Mode X and VESA modes are ignored; + +Otherwise, the VESA version of the mode is used. + +You can always see what video mode is selected from the console by typing +the command: + +vid_mode + +command. + +None of this has any effect on selecting modes through the +console, where all the different versions of each mode are +listed, and the desired version can be selected by using the +appropriate mode number. + + +How to get VESA 2.0 support +--------------------------- + +Some video adapters have VESA 2.0 support in ROM. Other video +adapters come with loadable VESA 2.0 TSRs. In the absence of either +of these, UniVBE, a shareware product from SciTech, provides VESA 2.0 +support for most video adapters. The latest version of UniVBE can be +obtained from the following locations: + +www: http://www.scitechsoft.com +ftp: ftp.scitechsoft.com +CIS: GO SCITECH +AOL: Keyword SciTech + +SciTech can be contacted at: + +email: sales@scitechsoft.com + +SciTech Software +5 Governors Lane, Suite D +Chico, CA +95926-1989 + +The current version at this writing is UniVBE 5.2. This version +supports many more adapters than previous versions, and adds +a number of useful low- and medium-resolution modes, such as 400x300 +and 512x384. + + +Video-related commands +---------------------- + +vid_describecurrentmode + lists the description for the current video mode. + +vid_describemode + lists the description for the specified video mode, where is as + reported by vid_describemodes. + +vid_describemodes + lists descriptions for all available video modes. + +vid_mode + sets the display to the specified mode, where is as reported by + vid_describemodes. + +vid_nopageflip <1|0> + when set to 1, VESA mode sets will always select non-page-flipped + operation. When set to 0, VESA mode sets will select page-flipped + operation whenever possible. All non-VESA modes are always + non-page-flipped. The setting of vid_nopageflip is remembered + when Quake is exited (by being saved in config.cfg), and is reloaded + when Quake is restarted, so once vid_nopageflip is set to 1, all + VESA modes set in all Quake sessions after that point be will non-page- + flipped until vid_nopageflip is set to 0. Note that setting this + variable doesn't affect whether the current video mode is page-flipped, + but rather whether page-flipping can be used by future mode sets. + +vid_nummodes + reports the total number of modes available. + +vid_testmode + tries to switch Quake to the specified mode, then returns to the current + mode after 5 seconds. This allows you to try an untested mode without + ending up with a black screen if, for example, the monitor can't display + the mode properly. There may still be instances in which, due to VESA + driver or hardware bugs, the machine will hang in certain modes; + vid_testmode can't recover from these situations, but it can recover + from a blank or scrambled screen. + +vid_wait + sets the type of waiting that the video adapter should do, as follows: + 0: no waiting + 1: wait for vertical sync active + 2: wait for display enable active + +The default state of vid_wait depends on the video mode selected. +(_vid_wait_override can force vid_wait to 1, wait for vertical +sync; see the description of _vid_wait_override below.) +In built-in modes 0-10, the default is always 0, no waiting. You +can set vid_wait to 1 (wait for vertical sync) to eliminate shear +and tearing in these modes (so partially-completed frames are never +drawn, resulting in a rock-solid image). However, waiting for +vertical sync can result in substantial performance loss. + +In VESA modes, if the adapter is VGA compatible and there's enough +memory for three video pages, then triple-buffering is enabled and +vid_wait is set to 2, wait for display enable. There is little +performance loss to this sort of waiting. If the adapter is not +VGA compatible, or if there's only enough memory for double-buffering, +then vid_wait is set to 1 (wait for vertical sync). This can cause +significant loss of performance, but some sort of wait is generally +necessary to avoid occasional glitching of the screen when +page-flipping; we always choose the lowest-cost wait option that +seems to be safe to use. If there's only enough memory for one +page, or if vid_nopageflip 1 is in effect, then vid_wait is set to 0 +(no wait). As with modes 0-10, vid_wait 1 can be used to eliminate +shear, but at a performance cost. + +We have encountered problems with a few adapters in VESA modes when +vid_wait is set to 2 (wait for display enable). Apparently some adapters +just toggle display enable all the time, rather than only when pixels +are being sent to the screen; this can cause occasional glitches in +which the screen image jumps for one frame. You can fix this by +setting vid_wait to 1 (wait for vertical sync). We would have made +vid_wait 1 the default, but it's slower, and vid_wait 2 works on most +machines. + +The default setting for vid_wait can be changed from the console +at any time. If you are in a VESA mode that waits for vertical +sync and want to turn it off to get a speed-up, you can do so. +However, changing a vid_wait 1 default in a VESA mode may result +in problems. If vid_wait defaults to 1 (wait for vertical sync) +in a mode, and you force it to 2 (wait for display enable), the +machine may hang, because some VGA-incompatible adapters, such as +some ATI Mach64s, don't support the display enable status. If you +force vid_wait to 0 (no wait), then the screen may glitch periodically +if the page flips at a time that results in a bad flip address, +although some adapters work fine with no wait at all. + +If you force a new setting for vid_wait and encounter problems, DO +NOT send us a bug report! + +_vid_wait_override <1|0> + can be used to force wait for vertical sync in all modes. When + _vid_wait_override is set to 0, the type of waiting, if any, for + each video mode that's set thereafter is automatically set to + what appears to be the fastest safe state. However, it is + possible in some cases that automatic setting may result in some + screen glitching, and it is also true that shear can be + eliminated by waiting for vertical sync (although at a cost in + performance), so it may be desirable in some cases to override + the automatic wait selection and always wait for vertical sync. + This can be done by setting _vid_wait_override to 1. Once set, + this remains in effect through all succeeding mode sets, even + when Quake is exited and re-entered; the only way to keep Quake + from waiting for vertical sync once _vid_wait_override is set to + 1 is to set _vid_wait_override to 0. Note that changing + _vid_wait_override doesn't affect the current mode, but rather + takes effect on the next mode set. _vid_wait_override is initially + set to 0. + +_vid_default_mode + can be used to force Quake to start up in a particular mode. + The easiest way to select a default mode is by pressing the + 'D' key in the Video Modes menu, but you can alternatively + use _vid_default_mode to specify the mode in which you want + Quake to start up in future Quake sessions. _vid_default_mode + is initially set to 0. + + +Higher-quality perspective texture mapping +------------------------------------------ + +For maximum speed, perspective correction is performed only every 16 +pixels. This is normally fine, but it is possible to see texture ripples +in surfaces that are viewed at sharp angles. For more precise texture +mapping, set the console variable d_subdiv16 to 0. Doing this will result +in somewhat slower performance, however, and the difference in visual +quality will not normally be noticeable. + + +Known video problems and workarounds +------------------------------------ + +If you think you've encountered a bug, see "Bug Reporting," below. +As a general rule, go back to mode 0 if you have problems; mode 0 +should work properly in all cases. + +On some ATI Mach64 adapters, the palette is sometimes too dark in +some VESA modes, and is tinted oddly (too red, for example) in other +modes. The workaround is to use different modes, or modes 0-10. + +In modes 0-10, shear and tearing can occur as partially finished +frames are displayed. Workaround: set vid_wait to 1 (wait for +vertical sync); this can result in a substantial performance loss, +however. An alternative is to use a page-flipped VESA mode. + +In page-flipped VESA modes, occasional glitched frames may occur with some +VESA driver-hardware combinations. Workaround: set vid_wait to 1 (wait +for vertical sync) (you can set _vid_wait_override to 1 to make waiting +for vertical sync permanent for future Quake sessions), or use a different +mode. + +The VESA video drivers that come with some video adapters don't +support low-resolution modes such as 320x200; often, +nothing lower than 640x400 is supported. For example, +this is the case with some ATI adapters. There's nothing +Quake can do to provide low-resolution VESA modes in these +cases, because Quake simply supports whatever modes the VESA +driver chooses to report as supported. Unfortunately, 640x400 +is too high a resolution for really good performance unless you +have a very fast Pentium or a Pentium Pro, so on machines with +this sort of adapter, the VESA modes aren't very usable. +Workaround: Use UniVBE 5.2, which supports low-resolution modes +on a wide variety of adapters. Note that a few adapters simply can't +support low-resolution modes, in which case you'll have to stick with +the low-resolution VGA and Mode X modes that are built into Quake, +which run fine but may be somewhat slower than VESA modes. + +A few video adapters are almost but not fully VGA compatible, because +they don't support some unusual VGA video modes. In particular, a few +adapters don't support the 360-wide Mode X-style video modes that are +build into Quake (modes 2, 4, 6, 8, and 10), and display garbage in those +modes. Workaround: use different modes, such as 0, 3, 5, 7, 9, or any +VESA modes that are available. + +Under Win 95, the palette occasionally gets messed up when switching from +Quake to the desktop and back again. You can restore the palette by +bringing down the console (either press tilde ('~'), or press Esc to bring +up the menu, select Options, and select Console... from the Options menu), +and typing bf and pressing the enter key, to generate a background flash, +which sets the palette. Press Esc to exit the console. Alternatively, +setting the screen brightness, either from the Options menu or via the +gamma console variable, sets the palette. + +Under Win 95, if the system key (the key with the Win 95 flag on it) is +pressed while Quake is running fullscreen in a VESA mode, Win 95 may be +unable to switch back from the desktop to Quake, in which case it will +notify you of this, then terminate the Quake session. This is a quirk +of Win 95, and normally there is no workaround other than not to press +that key or not to use VESA modes. (Some people go so far as to remove +the system key from their keyboard.) However, you can +disable the system key for Quake with the following utility: + +http://www.microsoft.com/windows/download/doswinky.exe + +Switching away from Quake with Alt-Enter, Ctrl-Esc, Alt-Tab, or +Alt-Spacebar all work fine (except that if you disable the system key +with doswinky.exe, Ctrl-Esc will also be disabled). + + +Performance +----------- + +Quake's graphics should be adequately fast in mode 0 (320x200) on all +Pentium-class machines. If you feel Quake is running slowly, set the +showturtle console variable to 1; you will then see a turtle icon +appear in the upper left corner of the screen if the frame rate drops +below 10 frame/second. If you are getting the turtle, you are probably +not getting great gameplay. Performance can be improved in several ways: + +* size down the screen with the minus key + +* select a lower-resolution mode, if possible + +* use a VESA mode + +* if you're using a VESA mode and vid_wait is set to 1 (wait for +vertical sync) by default (you can check by typing vid_wait +in the console), you can try setting vid_wait to 0 or 2, as detailed +in the discussion of the vid_wait command above. Be aware that +risks of screen glitching or hung machines are associated with +overriding a default vid_wait 1 setting in VESA modes. + +To see how exactly fast Quake is running, bring up the console and type + +host_speeds 1 + +You will see a display at the top indicating total frame time in +milliseconds, and also server, graphics, and sound frame time in +milliseconds. (Note, though, that unless you also do + +snd_noextraupdate 1 + +sound time will actually show up as graphics time. However, +snd_noextraupdate 1 can cause sound to get choppy, so it's not +generally recommended.) + +Lower numbers are better. + +Type + +host_speeds 0 + +to turn off the frame time display. + + +Pentium Pro Performance +----------------------- + +The Pentium Pro is a very fast Quake platform, but has one weak spot; it is +by default very slow on writes to video memory. This means that in default +hardware configurations, you are usually much better off setting +vid_nopageflip to 1 if you use VESA modes, so drawing is done to system +memory instead of to video memory. Remember that you must set the mode +after setting vid_nopageflip to 1 in order to get vid_nopageflip to take +effect. (vid_nopageflip can sometimes be faster on a Pentium, too, but +not by nearly as much in general, and it's often slower.) + +The Pentium Pro has some special features that are not turned on by default, +but which can help Quake performance a LOT. These features can be enabled +by John Hinkley's program FASTVID, which can be obtained from +ftp://members.aol.com/JHinkley/fastvid.zip. Performance in 640x480 +mode on a Pentium Pro/150 nearly doubled after FASTVID was run; Quake +was very playable (and looked great!) at this resolution. + +There's the usual caution with FASTVID: It could conceivably make your +system run goofily, or who knows what. FASTVID is not a product of +id Software, and id makes no guarantees regarding FASTVID. In other words, +use FASTVID at your own risk. + +************************************************************************ +IMPORTANT NOTE: FASTVID works only on Pentium Pros!!! Please do NOT +contact either John Hinkley or id with problems concerning FASTVID on +Pentium or 486 machines. +************************************************************************ + + +Video Bug Reporting +------------------- + +If you encounter a video-related bug, please fill out the form found at the +end of this file and e-mail it to support@idsoftware.com. There are several +problems that are not bugs, and shouldn't be reported, including: + +* unavailability of some VESA modes; VESA modes are only supported by +Quake if they are 8-bpp, are LFB modes (except for 320x200), and are +no greater than 1280x1024 in resolution. If you have a VESA mode +that doesn't seem to be working properly, please contact the +manufacturer; we just use the information that the VESA driver +provides us with. + +* problems that occur when you change vid_wait from a default value +of 1 (wait for vertical sync) in VESA modes + +* sluggish performance on 486s + +* the known palette problem on some Mach64s. + +* the known palette problems switching from fullscreen to the desktop and +back under Win95. + +* the known problems switching back from the desktop in VESA modes after the +system (Windows flag) key has switched from fullscreen to the desktop. + +* video modes that are not listed in the Video Modes menu, or that are not +listed or are listed with "**" in the output from vid_describemodes; such +modes are either not supported by your video adapter, or cannot be supported +by Quake in the amount of memory your system has. High-resolution modes will +often not be available in 8 Mb systems. + +* 360-wide video modes that don't work although other resolutions do work + +* lack of low-resolution VESA modes; the availability of low-resolution modes +is the responsibility of the VESA driver. UniVBE 5.2 provides low-resolution +modes on most adapters. + +Apart from these, we would very much like to hear about any video +problems you encounter. + + +========================================== +== Sound Subsystem Documentation == +========================================== + +Quake's sound subsystem works only with Sound Blaster compatible sound +cards. For Quake to get the correct settings for DMA channel and PORT +address, you must set your BLASTER environment variable (or have it set for +you with the DIAGNOSE utility in your SB16 directory). If you do not have +the BLASTER environment variable set, your sound will not work. If your +sound card supports Sound Blaster compatibility, Windows 95 should set this +variable for you. + +Note: some sound cards do not have 100% Sound Blaster compatible +hardware, but emulate the Sound Blaster interface. Such cards may +display some inconsistencies relative to an actual sound blaster. +In particular, sound may be delayed on some cards. + +Note: it is possible for sound to get choppy if the frame rate +drops to a very low level, below 5 frames a second. A frame rate +that low will not provide a good gameplay experience, so if you +do experience choppy sound, your machine is almost certainly not +fast enough to run Quake satisfactorily in general. + +If (when) you see bugs, please use the form attached to the end +of these docs to submit a bug report. + +Sound Card Command Line Options, Commands, and Variables +================================================================== + +The commands and variables below work under any operating system. +Command-Line options are typed on the command line in most any place +but only in operating systems which support command line interfaces, +like DOS's COMMAND.COM, or NEXTSTEP's or Linux's csh, sh, or bash. +For example, under DOS, the NOSOUND option would be used like this: +"C:> quake -nosound". + +Command-Line Options +-------------------- + +NOSOUND + Syntax: -nosound + Description: This will prevent *any* sound code from being executed. If + you are having technical difficulty with the game and then try + running the game with this option and the problem goes away, then + the problem is probably somewhere in the sound code. + +SSPEED + Syntax: -sspeed + Description: This will ask the sound code to set the playback speed + within the constraints of the capabilities of the card. This is + 11025 Hz by default and usually from 8000 to 44100. Making this + faster requires more CPU horsepower, and has no actual benefits, + because the sounds only contain 11 KHz data. Making this slower + degrades sound quality, but improves performance and saves memory. + +Commands +-------- + +SOUNDINFO + Syntax: soundinfo + Description: This prints the "portable" information on your current + audio hardware setting in the game. It specifies whether there is + stereo output (0 or 1), the number of samples in the DMA buffer, the + current sample position (changes each time you run SOUNDINFO and + ranges from 0 to the number of samples), the number of sample bits, + the submission chunk (1 in DOS or Linux w/ mmaped sound, larger in + Linux w/o mmaped sound), playback speed in Hz, the DMA buffer address + in hexadecimal (usually 8 digits after the 0x, starting with 0xf00.. + in DOS, starting with 0x400.. in Linux, and less than 8 digits if the + hardware was not initialized successfully), and the number of + channels mixed in software (8 by default, changeable w/NUMCHANNELS + command). + +STOPSOUNDS + Syntax: stopsounds + Description: Stops any current looping sounds. + + +Sound Blaster Sound Card Command-Line Options and Commands +========================================================== + +The following applies to Sound Blaster cards or compatibles under DOS +or a DOS box. + +Commands +-------- + +SBINFO + Syntax: sbinfo + Description: This will print information on the Sound Blaster card + in the system. If the version is 4 or greater, then it is some + kind of Sound Blaster 16 or compatible. Version 2 is an 8 bit mono + sound blaster, Version 3 is an 8 bit stereo sound blaster pro. + The port is the I/O port +sensed from the A variable in the BLASTER + environment variable. +The DMA is the DMA channel and is confirmed in + hardware if the +card is version 4 or higher. The mixer port can be + ignored. + + +========================================== +== CD Audio Subsystem Documentation == +========================================== + +Overview +======== +Quake is designed to play background music off of a CD-ROM. The Quake CD has +music tracks on it and each level has been assigned a track that will be +played. + +Win95 Users: Putting a CD other than the Quake CD into the drive when Quake +is already running will sometimes cause another Windows application to start +and switch you back to Windows with Quake running in the background. You +will probably want to stop whatever was started and switch back to Quake as +quickly as possible... especially if you are playing deathmatch. + + +Command Line Parameters +======================= +-nocdaudio + This will prevent the CD audio system from even attempting to initialize. + No CD commands or functions will be available. The game will just run + with no music. + +-cdmediacheck + This causes the game to periodically check to see if the CD has been + removed and a new one placed in the player. It is off by default since + this operation is very slow on some CD players and is not needed under + Win95. There is normally no reason to enable this option; it would + only be useful if you were going to be changing the CD from within the + game on a regular basis. + +Commands +======== +There is normally no reason you would need to use any of these commands. If +you are playing Quake with the Quake CD in your CD-ROM drive, the appropriate +music track will be played automatically. + +cd on + Re-enables the CD audio system after a "cd off" command. + +cd off + Shuts down the CD audio system. No more music will be played unless it + is re-enabled. + +cd reset + Causes the CD audio to re-initialize. This is useful if you change + CDs or insert the CD after you've already run Quake. + +cd play + Plays the specified track one time. + +cd loop + Plays the specified track. It will be repeated until either it is + manually stopped or another track is started. + +cd stop + Stops the currently playing track. + +cd resume + Will resume playback of a stopped track. + +cd eject + This is for CD players that do not have a manual eject button. + +cd remap ... + Allows you to switch what tracks are played. This is especially useful + if you want to play music other than that on the Quake CD. If the CD + audio system is told to play track 1, it will instead play the 1st + track you specified. For example: assuming a CD with 1 data track and + 8 music tracks, the command "cd remap 1 9 8 7 6 5 4 3 2" would leave + the data alone and play the audio tracks as if they had been placed on + the CD in the opposite order. + +cd info + Reports information such as the number and types of tracks on the current + CD, what track (if any) is currently playing, and the playback volume. + + +Variables +========= +bgmvolume + The background music volume. Valid values are 0.0 though 1.0. Changes + will normally be made using the options menu. + + Not all CD-ROM players support variable volume. The 0.0 to 1.0 value + translated to a value from 0 to 255 before it is passed to MSCDEX. How + this value is interpreted varies from drive to drive. The only thing + required by the MSCDEX specification is that 0 is off and anything else + is on. Some CD-ROM drives only have on and off so change to bgmvolume + will have have no effect on volume once it is on. + + +Messages +======== +CDAudio_Init: MSCDEX version 2.00 or later required. + MSCDEX was either not loaded, or is a version earlier than 2.00. + +CDAudio_Init: First CD-ROM drive will be used + MSCDEX reported that the system has more than one CD-ROM drive. + Quake will always use the first drive in this case. + +CDAudio_Init: Unable to allocate low memory. + We were unable to allocate the memory needed to communicate with MSCDEX. + Although the game can still run, this indicates a severe low memory + condition. + +CD Audio Initialized + Indicates that the CD audio system has successfully initialized. + +CDAudio_Play: Bad track number N. + We attempted to play a track number that that is outside the range of + tracks recorded on the CD currently in the CD-ROM drive. Probable causes + are that a CD other than Quake is in the player, or a custom level has + specified an invalid track number. + +CDAudio_Play: Can not play data. + A valid track was requested to be played, but it was a not an audio track. + The probable causes are the same as for a bad track number. + +CDAudio_Play: track N failed + A valid audio track was going to be played, but the play command to MSCDEX + returned an error. + +CDAudio: media changed + This is simply a notification. It can only occur if the "-cdmediacheck" + option was specified on the command line. + +CDAudio: Error - playback stopped N + An error occurred while the CD was playing audio. Playback has been + stopped and no further automatic play will be attempted; the game will + proceed without music. + +CDAudio_Init: No CD in player. + MSCDEX reported an error while Quake was attempting to get information + about the current CD. There is either no CD in the player, or it was + unable to get the track information. No automatic CD play will be + attempted; the game will proceed without music. + + +========================================== +== Network Subsystem Documentation == +========================================== + +Overview +======== + +Quake is a client/server game. You are always running over some type of +network. In a standalone game, you are using a loopback network; it just +passes messages back and forth in memory buffers. This readme is talking +about real networks and multiplayer deathmatches. There are three main +sections: commands, LANs, and Serial. + +Most normal configuration can be done via the game menus. + +There are two types of Quake servers: dedicated and listen. A listen server +is a machine that is used to play the game and also hosts the game for other +players. A dedicated server only hosts the game; it runs in text mode and +does not let anyone play on that machine. A single player game is really +just a 1 player listen server that doesn't listen for network connections. + +Dedicated vs Listen. I'll try to make this simple: it is always better to +use a dedicated server. Why? Fairness and playability. With a listen +server, the person on the server always has advantages. They will always be +the first person into a level, they will always have zero latency, and they +will get a server update on each and every frame. On a dedicated server +everyone gets equal treatment. Getting into the server is a first come, +first served proposition; latency is determined by each player's connection; +and everyone is sent the same number of updates. It's about as fair as life +gets. By the way, a good 486 machine works nicely as dedicated server. + +Another suggestion. Until there is a native Win95 version of Quake, IPX will +usually provide better gameplay on a local area network. This is due to the +delicate balancing act that is required to let a DOS program use the Win95 +TCP/IP stack. + +To start a Dedicated Server, you invoke Quake with the "-dedicated" +command-line parameter. When the server starts, you can type any command +that you would normally type in the Quake Console, such as "map e1m1" to +start the server on a specific map. This can be done from the command- +line as well by typing "quake -dedicated +map e1m1". If a value is entered +after "-dedicated", that is the amount of players allowed to connect, up +to a maximum of 16 players. A dedicated server will quit to the OS whenever +a fraglimit or timelimit is reached. Example: "quake -dedicated 16" will +start a 16-player dedicated server. + +To start a Listen Server, you invoke Quake with the "-listen" command- +line parameter, or use the Multiplayer menu in the game. Starting a listen +server from the command-line will allow you to handle more than 4 players, +as 4 is the limit when starting a game from the Multiplayer menu. If a +value is used after the "-listen", that is the maximum amount of players +allowed, up to 16 players. + +Command Line Parameters, Commands, and Variables +================================================ + +Command line parameters +----------------------- +-nolan + Disables IPX, TCP/IP, and serial support. + +-noudp + Disables support for TCP/IP. + +-udpport + Specifies a UDP port to be used other than the default of 26000. + +-noipx + Disables support for IPX. + +-ipxport + Specifies a IPX port to be used other than the default of 26000. + +-noserial + Disable serial support. + +-mpath + Enables support for code to use Win95's TCP/IP stack. Do NOT use this + under DOS! + +-listen [n] + Starts Quake ready to be a non-dedicated server for up to + players. If you do not specify a number after -listen it will + default to 8. The maximum allowed value is 16. + +-dedicated [n] + Starts Quake ready to be a dedicated server for up to players. + If you do not specify a number after -listen it will default to 8. + The maximum allowed value is 16. A dedicated Quake server stays in + text mode. This is the Quake console with most commands still + available; those that make no sense (like vid_mode) are ommitted. + +Console Variables +----------------- + +net_messagetimeout + Specifies how long Quake should wait for a message to arrive before + deciding the connection has died. The default is 3 minutes. For + reference, messages usually arrive at the rate of about 20 per second. + +hostname + This is the name for your server that will show up on an slist + (see below). The default value is "unnamed". + +sys_ticrate + Only used by dedicated servers. This determines the rate at which the + server will send out updates to the clients. The default value is 0.05 + (20 updatesper second). For servers where bandwidth is limited, using + modems or the internet for example, it is advisable to lower this value + to 0.1 (10 updates per second). This will have a very minor effect on + responsiveness, but will half to outbound bandwitdh required making the + modem players a lot happier. + + +Console commands +---------------- + +net_stats + This is for debugging. It displays various network statistics. + +slist + Looks for Quake servers on a local LAN (or over a null modem + cable). This will NOT go outside the local LAN (will not cross + routers). + + +LANs +==== + +Here are the LANs that are supported by the Quake test +release. For each one, you'll be told how to connect to a server +*if it is not on your local network*. If it is, you can use the +"slist" command and connect by hostname. See the main readme for +a discussion of the connect command. + +IPX +--- + +Quake has been run with Novell's ODI IPX stack under DOS, PDIPX with packet +drivers under DOS, and the Microsoft IPX stack in a Win95 DOS box. When +connecting to a server using IPX, you specify its network:nodeaddress (like +12345678:1234567890AB). If you are on the same network, you can just specify +the node address. If you are doing a connect command from the console, a +full IPX address must be enclosed in quotes. + +For example, the server's IPX address is "00FADE23:00aa00b9b5b2", you would +enter: connect "00FADE23:00aa00b9b5b2" + +Win95 TCP/IP +------------ + +Please see the Win95 section of this file for details about playing using +TCP/IP under Win95. + +Kali +---- + +To Quake, Kali appears to be IPX. Once you've got Kali up and running, run +Quake as if it was on an IPX network. + +Beame & Whiteside TCP/IP +------------------------ + +This is the only DOS TCP/IP stack supported in the test release. +It is not shareware...it's what we use on our network (in case you +were wondering why this particular stack). This has been "tested" +extensively over ethernet and you should encounter no problems +with it. Their SLIP and PPP have not been tested. When connecting +to a server using TCP/IP (UDP actually), you specifiy it's "dot notation" +address (like 123.45.67.89). You only need to specify the unique portion +of the adress. For example, if your IP address is 123.45.12.34 +and the server's is 123.45.56.78, you could use "connect 56.78". + +Playing over the Internet +------------------------- +Yes, you can play Quake over the Internet. How many people can be in +the game? That depends. How smooth will the game be? That depends. +There are just too many variables (bandwidth, latency, current load, +etc...) for us to make any kind of promises about Internet play. + + +Serial/Modem +============ + +The Quake serial driver supports two COM ports. Although they are referred +to as COM1 and COM2, you can configure them to use any normal hardware +COM port (1 thru 4 on most PCs). The com ports are used with interrupts, +so their IRQ may not be used for another purpose (such as a LAN adapter +or sound card). The IRQ may not be shared with another device either; +not even another COM port. A client can only be connected to one server +at a time, so multiple ports are really only useful on a server. +When using modems, the client must originate the call and the server +must answer. This holds true even for a two player, non-dedicated +server configuration. + +In the Multiplayer menu, the default modem string is "ATZ". If your modem +games are too slow, you can change this string to the appropriate one for +your modem as listed below in the "Modem Strings" section. + + +The COMx commands +----------------- + +Use the menus for serial play whenever possible. The console +interface is only for unusual configurations. It is much more +difficult to understand and use correctly. + +Those of you who do use the console commands for serial play need to +know that the menus always use the first Quake COM line (COM1); yes, +even for COM2. The names COM1 and COM2 here mean the first and second +serial ports, not necessarily the PC COM1 and COM2 ports (although those +are the default configurations). + +There are two commands to support serial/modem play for Quake. They +are: COM1 and COM2. Entering one of these commands with no arguments +will display the status of that serial port, similar to this: + +Settings for COM1 +enabled: true +connected: false +uart: 16550 +port: 3f8 +irq: 4 +baud: 57600 +CTS: ignored +DSR: ignored +CD: ignored +clear: ATZ +startup: +shutdown: ATH + +When used with arguments, these commands change the settings and +status of the COM ports. The possible arguments are listed below; +examples follow. + +enable | disable + "enable" means that your configuration is complete and you want to use + the COM port. "disable" is used to turn off a COM port, usually to + change its settings. The default (initial) state is disabled. + + +modem | direct + Use one of these two to let Quake know if you are using a modem or a + direct connection (also called a null modem). Quake uses this to know + if it needs to handles modem initialization strings, dialing sequences, + and hangup procedures. + +reset + This will reset the COM port to its default settings and state. + + +port +irq + These are used to set the I/O Port and IRQ that your serial port uses. + The default values are: port=3f8 irq=4 for COM1 and port=2f8 irq=3 for + COM2. Note that the port number is displayed in hexadecimal; to enter + it you would use something like "COM2 port 0x2f8"; the "0x" preceding + the "2f8" indicates that you are giving the value in hexadecimal + otherwise decimal is assumed. + + +baud + Sets the baud rate. Valid values for are: 9600, 14400, + 28800, 57600, and 115200. 57600 is the default. Please note that + this is the baud rate used for the uart, not your modem. It is + perfectly valid to use 57600 on a COM port that is connected to a + 28.8 modem. + +8250 | 16550 + Specifies the type of uart chip in your system. Normally this is + automatically detected, one of these need only be used if your chip + is incorrectly detected. + +clear +startup +shutdown + This allows you to specify the clear, startup, and shutdown strings + needed for +a modem for playing Quake. If you've found values that + previously worked +with Doom, use them here. If you are playing over + a null modem cable, +leave these blank. + +-cts | +cts +-dsr | +dsr +-cd | +cd + These determine if certain serial control lines should be honored or + ignored. The "-" means you want that line ignored, the "+" means to honor + it. "cts" is an abbreviation for "clear to send", "dsr" for + "data set ready", and "cd" for "carrier detect". Do not +change these + values unless you are absolutely positive you need to. The default is to + ignore all 3 lines. + +Quake always uses no parity, 8 data bits, and 1 stop bit; these +values can not be changed. The baud, port, irq, and uart type can +not be changed on an enabled port, you must disable it first. + + +Configuration examples +---------------------- +Example1: You have a machine with two serial ports you are going +to use as a Quake server. COM1 will be using a null modem cable and +COM2 will be connected to a 14.4 modem. You would use commands similar +(the startup string would almost certainly be different) to these: + +COM1 baud 57600 enable +COM2 baud 14400 modem startup AT\N0%C0B8 enable + + +Example2: You are going to use your machine to connect to a dial-up +Quake server with your 28.8 modem connected to COM2. You would +use a command something like this: + +COM2 baud 57600 modem startup AT\N0%C0B8 enable + +Note the baud rate is not the same as the modem speed. This allows +the modem-to-uart communications to occur at a higher rate than +the modem-to-modem communications. + +Connecting to a serial Quake server +----------------------------------- + +Connecting to a Quake server over a serial/modem connection is done +using the "connect" command. The command "connect 5551212" would try to +connect to a Quake server at the phone number 555-1212. Note: your local +phone company would probably appreciate it if you didn't try this number! + +If you are using a null modem cable, you can type "connect #". +Quake will then attempt to connect to the server. + + +Known problems / workarounds +============================ +Packet drivers with PDIPX - there is a bug that stops a server running on +this combination from responding to the slist command. Use the patched +version of PDIPX included with Quake to correct this problem. + +SLIST sees no servers - Some PCMCIA ethernet cards and PPP drivers will +not do the UDP broadcasts needed for the SLIST command (search for local +games from the menu) to function correctly. In these cases you must +connect to a Quake game using either its IP address or hostname +(DNS resolvable hostname, not the hostname variable in Quake). + +"BW_OpenSocket failed: 5" - This error is specific to the Beame and +Whitesdie TCP/IP stack. This stack uses DOS file handles as it's +socket handles. This error occurs when DOS runs out of file handles. +You need to increase the number specified by "FILES=" in the DOS +config.sys file. + +Severe lag using TCP/IP under Win95: + - Occasionaly when you first connect in to a Quake game using Win95 +TCP/IP you will experience severe lag and not be able to control your +player's actions. This usually clears up in 10 to 15 seconds. + - There is apparently a strange limbo state for Microsoft's File and +Print sharing. This has been seen when it was installed and then later +removed, but it still appears on the menus. For some unknown reason +this causes severe lag for a Quake game.

However, it runs fine from the MS-DOS prompt +under Win95, so long as the Properties for the MS-DOS prompt are set up so +that Quake can run. (See "Set the MS-DOS Prompt Properties", below, for +information about setting MS-DOS Prompt Properties.) Quake will NOT run +under Windows NT. Following are some steps that can help Quake run better +under Win95. + + +Have enough memory +------------------ + +Quake requires at least 16 Mb of installed memory in order to run under +Win95. + + +Set the MS-DOS Prompt Properties +-------------------------------- + +If Quake won't run, the MS-DOS Prompt Properties may not be set correctly. +To set the Properties for the MS-DOS prompt, bring up a DOS session, and +either click on the MS-DOS icon in the upper left corner or press +Alt-Spacebar, then select Properties from the menu that comes up, and make +sure the following settings are correct. + +In the Program sheet of MS-DOS Prompt Properties, make sure the "Suggest +MS-DOS mode as necessary" is checked. + +In the Memory sheet of MS-DOS Prompt Properties, make sure all five fields +are "Auto". + +In the Screen sheet of MS-DOS Prompt Properties, set "Usage" to Full-screen. + +In the Misc sheet of MS-DOS Prompt Properties, uncheck the "Allow screen +saver" box, and check the "Always suspend" box. + + +Make sure there's enough free disk space +---------------------------------------- + +If you get error messages like "can't lock memory" under Win 95, or if you +get other weird, inexplicable errors, make sure you haven't run out of disk +space; delete some files if necessary. You can see how much disk space is +free by bringing up "My Computer" and clicking on the disk icon; the free +disk space will be shown at the bottom of the window. + + +Run fullscreen +-------------- + +Quake can run in a window under Win95--but it will run very slowly. You are +unlikely to get satisfactory performance unless you run Quake fullscreen. +Quake normally comes up fullscreen under Win95; if you have switched it back +to windowed mode, you can get that window back to fullscreen by clicking on +it and then pressing Alt-Enter. + + +Shut down other applications +---------------------------- + +Many Win95 apps and DOS apps run even when they're not the foreground +application. Such applications contend for system resources such as memory, +processor cycles, and sound hardware. If Quake seems to be running choppily, +if sound is garbled, or if the disk is going all the time, try shutting down +whatever other applications you have running. For example, some players +have reported that Quake does not run as well when the Office shortcut bar +is running. + + +Restore the palette if it gets garbled +-------------------------------------- + +Under Win 95, the palette occasionally gets messed up when switching from +Quake to the desktop and back again. You can restore the palette by +bringing down the console (either press tilde ('~'), or press Esc to bring +up the menu, select Options, and select Console... from the Options menu), +and typing bf and pressing the enter key, to generate a background flash, +which sets the palette. Press Esc to exit the console. Alternatively, +setting the screen brightness, either from the Options menu or via the +gamma console command, sets the palette. + + +Avoid the system key +-------------------- + +Under Win 95, if the system key (the key with the Win 95 flag on it) is +pressed while Quake is running fullscreen in a VESA mode, Win 95 may be +unable to switch back from the desktop to Quake, in which case it will +notify you of this, then terminate the Quake session. This is a quirk +of Win 95, and there is no workaround other than not to press that key +or not to use VESA modes. (Some people go so far as to remove the system +key from their keyboard.) Switching away from Quake with Alt-Enter, +Ctrl-Esc, Alt-Tab, or Alt-Spacebar all work fine. + + +Give Quake more and/or locked memory +------------------------------------ + +By default, Quake tries to allocate 8 Mb of unlocked memory for heap space +under Win 95. More memory helps Quake run faster; you can allocate more +memory for Quake under Win95 by setting the command-line switch + +-winmem x + +where x is the number of megabytes to allocate for Quake. If there's enough +memory in the system, the larger the number, up to about 16, the better the +performance. If, however, there isn't enough memory in the system, or many +other applications are running, the larger number can just cause Quake to +page to disk a lot, and can actually slow performance considerably. Also, +higher numbers can also cause Win 95 to take longer to start Quake and take +longer to return to the desktop afterward. If you have 32 Mb or more in your +machine, -winmem 16 should provide the best performance for Quake. If you +have less than 32 Mb, or a lot of applications running, then you will have +to experiment to find the best amount of memory to allocate for Quake. + +You may optionally instruct Quake to lock itself in memory by using the +command-line switch + +-winlock + +so it won't get paged out by other applications. This can avoid hitches when +parts of Quake get paged into and out of memory, and thus provide a smoother +playing experience. On the other hand, it can cause Quake to take longer to +start, and can make the return to the desktop take longer when Quake ends, +because Quake has been hogging a lot of memory. It is even possible, if most +of the memory in the system is locked by Quake, that it will take many +minutes to switch back to the desktop while Quake is running, so the system +will effectively be nearly frozen. Therefore, use -winlock with caution; +Quake is not as well-behaved a Win95 citizen when -winlock is specified, and +does not share resources particularly well. + +-winmem can be used in conjunction with -winlock; if -winmem specifies more +memory than is available to be locked, then Quake will lock as much memory +as possible. Being too aggressive about how much memory is locked can +actually slow Quake performance, because unlocked parts of the system like +system CD and sound code and data can then be forced to page, so if you do +lock memory, you will have to experiment to find the sweet spot, unless you +have 32 Mb or more of memory. + +-winlockunlock can be specified as an alternative to -winlock, to tell Quake +to lock its memory when it starts, then immediately unlock it. The +advantages of doing this are: 1) it forces all of Quake's pages into memory, +so no pages should need to be brought in as Quake runs, making for smoother +running at the start, and 2) it enables Quake to determine whether the +specified amount of memory (if -winmem is also specified) is available in the +machine, so you can be sure Quake won't try to allocate more heap space than +the the amount of physical memory that's actually available. Like -winlock, +-winlockunlock causes Quake to take quite a bit longer to start up, but it +has the advantage of making Quake a good Win95 citizen if you need to switch +back to the desktop, or have other apps running. + +In general, Quake will run fine without any of the -winxxx switches, but you +may find that one or more of them--particularly -winmem if you have more than +16 Mb--helps Quake performance on your machine. + +None of this is an issue under DOS itself (as oppsed to a DOS box under +Win95), because Quake just uses all the memory in the machine under DOS. + +By default, Quake tries to allocate 8 Mb of unlocked memory for heap space + + +Watch out for limbo subsystems +------------------------------ +Microsoft's File and Print sharing and IPX protocol stack have both been +known to cause strange problems when they are in a limbo state. The limbo +state is seems to be an uninstall that did not complete succesfully. Both +of these cause poor network play performance. If you are experiencing +severe lag, check the File and Print services. If you the warning "IPX +driver send failue: 04", check the IPX protocol stack. They need to be +either completely installed or removed; the problems only occur when they +get into this strange semi-installed state. + + +========================================== +== Key Binding and Aliases == +========================================== + +Pressing the tilde key ("~") will bring down the console (pressing the +tilde key or ESC while in the console will close the console). From the +console you can adjust your player controls, this is done by "binding" +keys to commands. The format for binding keys is as follows: + +bind + +Where is a valid key control and is a valid quake command. + +Example: +To bind the j key to the 'jump' command, you would type: +bind j +jump +and press enter. + +Non-printable keys such as 'page up' and buttons from the mouse/joystick are +bound in the same manner as printable characters. A list of bindable keys can +be found at the end of this file. + +Example: +To bind the page up key to the 'jump' command, you would type: +bind pageup +jump +and press enter. + +To bind the right mouse button to the attack command, you would type: +bind mouse2 +attack +and press enter. + +The alias command is used to create a reference to a command or list of +commands. When aliasing multiple commands, or commands that contain +multiple words (such as "fraglimit 50"), you must enclose all the commands +in quotation marks and separate each command with a semi-colon. + +Example of an alias that changes some Deathmatch server parameters: + +alias net_game "hostname my_server ; fraglimit 15 ; timelimit 15" +bind INS net_game + +Once the server is spawned (you must be the one running the -listen server), +you just push the Insert key to set the hostname, frag limit and time limit +of the server. So now the first person to 15 frags, or with the one with the +most frags in 15 minutes, wins. + +Another example would be to change to the Rocket Launcher, fire one rocket, +and change back to the Double Barrel Shotgun, when you press the "," key: + +alias rl_dbsg "impulse 7 ; +attack ; wait ; -attack ; impulse 3" +bind , rl_dbsg + +Aliasing is very powerful, allowing you great flexibility, so you should +experiment by aliasing different commands in various ways. + +A list of common commands can be found in the next section. + + +========================================== +== Quake Keys and Common Commands == +========================================== + +The following keys can be bound: + +A-Z 0-9 +*F1-F12 *TAB +ENTER SPACE +BACKSPACE UPARROW +DOWNARROW LEFTARROW +RIGHTARROW ALT +CTRL SHIFT +INS DEL +PGDN PGUP +HOME END +PAUSE SEMICOLON + +MOUSE1 (mouse button 1) +MOUSE2 (mouse button 2) +MOUSE3 (mouse button 3) + +*~ (tilde) + +* Can only be bound on the command line or in a .cfg file. + +The ESC key cannot be bound. + + +========================================== +== Making a Config File == +========================================== + +The commands (bindings and aliases) discussed above can be included into a +file containing all of your personal configurations, known as a "config" +file. This file can then be loaded during game play to enable all your +personal bindings and settings. + +To do this, use your favorite editor to create a new file, such as +"fragmstr.cfg". Your .cfg file MUST be located in the quake\id1 directory +or quake won't find it. Then after launching Quake, you would type "exec +fragmstr.cfg" and press enter, from the console. You can also exec you .cfg +file from the DOS command prompt by typing "quake +exec fragmstr.cfg". +When you exec a config file, it is the same as typing all the lines in your +config file into the console, only Quake does it for you. Here is an +example config file (c:\quake\id1\bear.cfg) and the meaning of all the +bindings, aliases and settings: + +-------------------------------cut here------------------------------------- +name player1 // Sets player name to player1 (lets your opponent + // know who fragged them) + +sensitivity 4 // Sets the mouse sensitivity to 4 + +scr_conspeed 5000 // Sets the console raise/lower speed + +lookspring 0 // Sets Mouse Look Spring to 0 (0=keep looking, + // 1=spring back, when mouse button is released) + +vid_mode 10 // Sets Video Mode to mode 10 (360X480 resolution) + +gamma .8 // Sets Gamma Correction to .8 (<1=Lighter, 1=normal + // and >1=darker) + +viewsize 70 // Sets the Screen View size to 70 degrees + +bind mouse1 +forward // Binds the left mouse button to Move Forward + +bind mouse3 +attack // Binds the middle mouse button to Fire + +bind mouse2 +mlook // Binds the right mouse button to Mouse Look + +bind HOME "save bear1" // Binds the Home Key to quick save, saves to + // bear1.sav + +bind ENTER +showscores // Binds the Enter key to show Deathmatch Scores + +bind SHIFT +speed // Binds the Shift key to Run + +bind CTRL +jump // Binds the Control key to Jump + +bind ; +mlook // Binds the ; key to Mouse Look also + +bind . +moveleft // Binds the . key to Strafe Left + +bind / +moveright // Binds the / key to Strafe Right + +color 3 4 // Makes Uniform Top green and Pants Red for Net play + +alias rl_dbsg "impulse 7 ; +attack ; wait ; -attack ; impulse 3" + +bind , rl_dbsg // Aliases single rocket attack command and binds + // it to the ',' key. +-------------------------------cut here------------------------------------- + + +========================================== +== Demos == +========================================== + +The standard Demos +------------------ + +Quake has 3 standard demos that start playing when you first run the game. +It will cycle through these demos until you start or join a game. + +Recording a Demo +---------------- +"record [track]" This starts up level and begins +recording a demo into a file name .dem. You can specify the +optional to choose a background music from the CD, otherwise the +default selection for that map will be played. + +Playing a Demo +-------------- +"playdemo " This command will open the file .dem and +play the demo. + +How to not play the standard demos at startup +--------------------------------------------- + +So you've seen the Necropolis demo 10 billion times now and really don't +ever want to see it again? Here's how. + +The easy way is to start Quake with a "+map" command. You could do +"quake +map start" and you'll start on the single player start level. +Or you could do "quake +map nonsense" and you'll wind up at the Quake +console since there is no map named nonsense. You can accomplish the +same thing with a "+connect" too. "+connect" by itself will look for +Quake servers on the local network, "+connect 192.12.34.56" or +"+connect host.timbuktu.edu" will try to connect the the specified +Quake server. + +There is another way to not show the demos; one that also keeps your +customizations in a seperate directory from the data files in the +Quake distribution. + +Do this in the quake directory (the directory where you installed Quake; +where you find "quake.exe" and "the id1" directory). Create a file named +"quake.rc". Its contents should be: + +exec default.cfg +exec config.cfg +exec autoexec.cfg +stuffcmds +menu_main + +Create a batch file to run Quake in the quake directory. "Q.BAT" is a good +name. It's contents should be: + +quake -game . %1 %2 %3 %4 %5 %6 %7 %8 %9 + +If you normally use the Q95 batch file, just add the "-game ." part to +that file. + +Now you can run "q" and quake will start off with the main menu displayed +instead of running the demos. + +You can also make a seperate subdirectory for this if you'd like. For +example, make a directory named "mine" in the quake directory. Create +the "quake.rc" file as specified above in this directory. Use +"-game mine" instead of "-game ." in your batch file. + +Important note: The directory specified by "-game" is where Quake will +look for config.cfg, load and save games, and record and play +demos. + + +========================================== +== Reporting Quake Bugs == +========================================== + +How to use the bug report: + +Where to send bug reports: +E-mail : support@idsoftware.com +FAX : 214-686-9288 + +There are two sections of information - primary and secondary. + +Primary information contains information such as date, your name, e-mail +address, etc. Secondary information is actual bug information.

Only fill out and include information from the section +related to the type of bug you received. + +If possible, start Quake with the "-condebug" command line parameter +and try to reproduce the bug. Attach the "qconsole.log" file found in the +"id1" directory to the end of the bug report. If the bug is sound related, +while in Quake, execute the SOUNDINFO and SBINFO (DOS only) commands from +the console. + +Please attach a copy of your CONFIG.SYS and AUTOEXEC.BAT file to the end of +the report. + +Bugs submitted properly with this form will get attention. +Unformatted ones sent to personal accounts will be ignored. +If you see problems, please take the time to do this. + +If you do not have all of the information requested in the form, +don't worry.

Most +users will want to set this to "off" in /etc/vga/libvga.config. + +Additional notes for GLQuake +---------------------------- + +There are three different ways to execute GLQuake: + +1. The binary "glquake" requires Mesa 3-D 2.5 or later installed and compiled +with 3DFX support (fxMesa..() function interface). It also requires +svgalib 1.3.0 or later for keyboard/mouse input. This binary is a console +application. Mesa 3-D requires GLIDE to be installed. + +2. The shell script "glquake.3dfxgl" runs the "glquake" binary after +preloading the lib3dfxgl.so library. This is a port of 3DFX's Win32 +OpenGL MCD (Mini Client Driver) to Linux. It is faster than Mesa 3-D +since it was written specifically with supporting GLQuake in mind. +lib3dfxgl.so requires that GLIDE be installed. + +3. The binary "glquake.glx" is linked against standard OpenGL libraries. +It should run on many different hardward OpenGL implementations under +Linux and X11. This binary is an X11 application and must be run under +X11. It will work with Mesa 3-D as a standard glX based OpenGL +applications. If the Mesa 3-D library is compiled with 3DFX support, +you can have Mesa 3-D support 3DFX hardware under X11 by setting the +enviroment variable "MESA_GLX_FX" to "fullscreen" for fullscreen mode +and "window" for windowed mode, eg. "export MESA_GLX_FX=fullscreen" for sh +or "setenv MESA_GLX_FX fullscreen" for csh. + +For glquake, you must also have SVGALib or later installed (1.3.0 or later +prefered). GLQuake uses SVGALib for mouse and keyboard handling. + +If you have gpm and/or selection running, you will have to terminate them +before running GLQuake since they will not give up the mouse when GLQuake +attempts to run. You can kill gpm by typing 'killall gpm' as root. + +You must run GLQuake as root or setuid root since it needs to access things +such as sound, keyboard, mouse and the 3DFX video.

The binary "glquake" requires Mesa 3-D 2.5 or later installed and compiled +with 3DFX support (fxMesa..() function interface). It also requires +svgalib 1.3.0 or later for keyboard/mouse input. This binary is a console +application. Mesa 3-D requires GLIDE to be installed. + +2. The shell script "glquake.3dfxgl" runs the "glquake" binary after +preloading the lib3dfxgl.so library. This is a port of 3DFX's Win32 +OpenGL MCD (Mini Client Driver) to Linux. It is faster than Mesa 3-D +since it was written specifically with supporting GLQuake in mind. +lib3dfxgl.so requires that GLIDE be installed. + +3. The binary "glquake.glx" is linked against standard OpenGL libraries. +It should run on many different hardward OpenGL implementations under +Linux and X11. This binary is an X11 application and must be run under +X11. It will work with Mesa 3-D as a standard glX based OpenGL +applications. If the Mesa 3-D library is compiled with 3DFX support, +you can have Mesa 3-D support 3DFX hardware under X11 by setting the +enviroment variable "MESA_GLX_FX" to "fullscreen" for fullscreen mode +and "window" for windowed mode. + +You must also have SVGALib 1.3.0 or later installed. GLQuake uses SVGALib +for mouse and keyboard handling. + +If you have gpm and/or selection running, you will have to terminate them +before running GLQuake since they will not give up the mouse when GLQuake +attempts to run. You can kill gpm by typing 'killall gpm' as root. + +You must run GLQuake as root or setuid root since it needs to access things +such as sound, keyboard, mouse and the 3DFX video. Future versions may not +require root permissions. + +resolution options +------------------ +glquake -width 512 -height 384 +Tries to run glquake at the specified resolution. +Only highend VooDoo cards support such high resolutions (most +cards on the market right now do not). Another popular and supported mode +is 512x384 (-width 512 -height 384) which can offer a faster speed than +the default 640x480. + +You can also specify the resolution of the console independant of the screen +resolution. + +glquake -conwidth 320 +This will specify a console resolution of 320 by 240 (the height is +automatically determined by the default 4:3 aspect ratio, you can also +specify the height directly with -conheight). + +In higher resolution modes such as 800x600 and 1024x768, glquake will default +to a 640x480 console, since the font becomes small enough at higher +resolutions to become unreadable. If do you wish to have a higher resolution +console and status bar, specify it as well, such as: +glquake -width 800 -height 600 -conwidth 800 + +texture options +--------------- +The amount of textures used in the game can have a large impact on performance. +There are several options that let you trade off visual quality for better +performance. + +There is no way to flush already loaded textures, so it is best to change +these options on the command line, or they will only take effect on some of +the textures when you change levels. + +OpenGL only allows textures to repeat on power of two boundaries (32, 64, +128, etc), but software quake had a number of textures that repeated at 24 +or 96 pixel boundaries. These need to be either stretched out to the next +higher size, or shrunk down to the next lower. By default, they are filtered +down to the smaller size, but you can cause it to use the larger size if you +really want by using: + +glquake +gl_round_down 0 +This will generally run well on a normal 4 MB 3dfx card, but for other cards +that have either worse texture management or slower texture swapping speeds, +there are some additional settings that can drastically lower the amount of +textures to be managed. + +glquake +gl_picmip 1 +This causes all textures to have one half the dimensions they otherwise would. +This makes them blurry, but very small. You can set this to 2 to make the +textures one quarter the resolution on each axis for REALLY blurry textures. + +glquake +gl_playermip 1 +This is similar to picmip, but is only used for other players in deathmatch. +Each player in a deathmatch requires an individual skin texture, so this can +be a serious problem for texture management. It wouldn't be unreasonable to +set this to 2 or even 3 if you are playing competatively (and don't care if +the other guys have smudged skins). If you change this during the game, it +will take effect as soon as a player changes their skin colors. + +run time options +---------------- +At the console, you can set these values to effect drawing. + +gl_texturemode GL_NEAREST +Sets texture mapping to point sampled, which may be faster on some GL systems +(not on 3dfx). + +gl_texturemode GL_LINEAR_MIPMAP +This is the default texture mode. + +gl_texturemode GL_LINEAR_MIPMAP_LINEAR +This is the highest quality texture mapping (trilinear), but only very high +end hardware (intergraph intense 3D / realizm) supports it. Not that big of +a deal, actually. + +gl_finish 0 +This causes the game to not issue a glFinish() call each frame, which may make +some hardware run faster. If this is cleared, the 3dfx will back up a number +of frames and not be very playable. + +gl_flashblend 0 +By default, glquake just draws a shaded ball around objects that are emiting +light. Clearing this variable will cause it to properly relight the world +like normal quake, but it can be a significant speed hit on some systems. + +gl_ztrick 0 +Glquake uses a buffering method that avoids clearing the Z buffer, but some +hardware platforms don't like it. If the status bar and console are flashing +every other frame, clear this variable. + +gl_keeptjunctions 0 +If you clear this, glquake will remove colinear vertexes when it reloads the +level. This can give a few percent speedup, but it can leave a couple stray +blinking pixels on the screen. + +novelty features +---------------- +These are some rendering tricks that were easy to do in glquake. They aren't +very robust, but they are pretty cool to look at. + +r_shadows 1 +This causes every object to cast a shadow. + +r_wateralpha 0.7 +This sets the opacity of water textures, so you can see through it in properly +processed maps. 0.3 is very faint, almost like fog. 1 is completely solid +(the default). Unfortunately, the standard quake maps don't contain any +visibility information for seeing past water surfaces, so you can't just play +quake with this turned on. If you just want to see what it looks like, you +can set "r_novis 1", but that will make things go very slow. When I get a +chance, I will probably release some maps that have been processed properly +for this. + +r_mirroralpha 0.3 +This changes one particular texture (the stained glass texture in the EASY +start hall) into a mirror. The value is the opacity of the mirror surface. + diff --git a/contrib/other/sdlquake-1.0.9/docs/readme.squake b/contrib/other/sdlquake-1.0.9/docs/readme.squake new file mode 100644 index 000000000..3d4ba918d --- /dev/null +++ b/contrib/other/sdlquake-1.0.9/docs/readme.squake @@ -0,0 +1,127 @@ + +README for Linux SVGALib Quake +------------------------------ + +Requirements: + +- SVGALib 1.20 or later (/lib/libvga.so.1.2.10) +- libc 5.2.18 or later (5.0.9 will not work, /lib/libc.so.5.2.18) +- CD-ROM for CDAudio +- Soundcard capable of mmap'd buffers.

DO NOT install +the opengl32.dll unless you have a 3dfx! Glquake should change the screen +resolution to 640*480*32k colors and run full screen by default. + +If you are running win-95, your desktop must be set to 32k or 64k colors +before running glquake. NT can switch automatically. + +Theoretically, glquake will run on any compliant OpenGL that supports the +texture objects extensions, but unless it is very powerfull hardware that +accelerates everything needed, the game play will not be acceptable.

Other opengl applications are +very unlikely to work with it, so consider it basically a "glquake driver". +See the encluded 3dfx.txt for specific instalation notes. 3dfx can only run +full screen, but you must still have your desktop set to a 16 bit color mode +for glquake to start. + +resolution options +------------------ +We had dynamic resolution changing in glquake for a while, but every single +opengl driver I tried it on messed up in one way or another, so it is now +limited to startup time only. + +glquake -window +This will start glquake in a window on your desktop instead of switching the +screen to lower resolution and covering everything. + +glquake -width 800 -height 600 +Tries to run glquake at the specified resolution. Combined with -window, it +creates a desktop window that size, otherwise it tries to set a full screen +resolution. + +You can also specify the resolution of the console independant of the screen +resolution. + +glquake -conwidth 320 +This will specify a console resolution of 320 by 240 (the height is +automatically determined by the default 4:3 aspect ratio, you can also +specify the height directly with -conheight). + +In higher resolution modes such as 800x600 and 1024x768, glquake will default +to a 640x480 console, since the font becomes small enough at higher +resolutions to become unreadable. If do you wish to have a higher resolution +console and status bar, specify it as well, such as: +glquake -width 800 -height 600 -conwidth 800 + +texture options +--------------- +The amount of textures used in the game can have a large impact on performance. +There are several options that let you trade off visual quality for better +performance. + +There is no way to flush already loaded textures, so it is best to change +these options on the command line, or they will only take effect on some of +the textures when you change levels. + +OpenGL only allows textures to repeat on power of two boundaries (32, 64, +128, etc), but software quake had a number of textures that repeated at 24 +or 96 pixel boundaries. These need to be either stretched out to the next +higher size, or shrunk down to the next lower. By default, they are filtered +down to the smaller size, but you can cause it to use the larger size if you +really want by using: + +glquake +gl_round_down 0 +This will generally run well on a normal 4 MB 3dfx card, but for other cards +that have either worse texture management or slower texture swapping speeds, +there are some additional settings that can drastically lower the amount of +textures to be managed. + +glquake +gl_picmip 1 +This causes all textures to have one half the dimensions they otherwise would. +This makes them blurry, but very small. You can set this to 2 to make the +textures one quarter the resolution on each axis for REALLY blurry textures. + +glquake +gl_playermip 1 +This is similar to picmip, but is only used for other players in deathmatch. +Each player in a deathmatch requires an individual skin texture, so this can +be a serious problem for texture management. It wouldn't be unreasonable to +set this to 2 or even 3 if you are playing competatively (and don't care if +the other guys have smudged skins). If you change this during the game, it +will take effect as soon as a player changes their skin colors. + +GLQuake also supports the following extensions for faster texture operation: + +GL_SGIS_multitexture +Multitextures support allows certain hardware to render the world in one +pass instead of two. GLQuake uses two passes, one for the world textures +and the second for the lightmaps that are blended on the textures. On some +hardware, with a GL_SIGS_multitexture supported OpenGL implementation, this +can be done in one pass. On hardware that supports this, you will get a +60% to 100% increase in frame rate. Currently, only 3DFX dual TMU cards +(such as the Obsidian 2220) support this extension, but other hardware will +soon follow. + +This extension will be autodetected and used. If for some reason it is not +working correctly, specify the command line option "-nomtex" to disable it. + +GL_EXT_shared_texture_palette +GLQuake uses 16bit textures by default but on OpenGL implementations +that support the GL_EXT_shared_texture_palette extension, GLQuake will use +8bit textures instead. This results in using half the needed texture memory +of 16bit texture and can improve performance. This is very little difference +in visual quality due to the fact that the textures are 8bit sources to +begin with. + +run time options +---------------- +At the console, you can set these values to effect drawing. + +gl_texturemode GL_NEAREST +Sets texture mapping to point sampled, which may be faster on some GL systems +(not on 3dfx). + +gl_texturemode GL_LINEAR_MIPMAP +This is the default texture mode. + +gl_texturemode GL_LINEAR_MIPMAP_LINEAR +This is the highest quality texture mapping (trilinear), but only very high +end hardware (intergraph intense 3D / realizm) supports it. Not that big of +a deal, actually. + +gl_finish 0 +This causes the game to not issue a glFinish() call each frame, which may make +some hardware run faster. If this is cleared, the 3dfx will back up a number +of frames and not be very playable. + +gl_flashblend 0 +By default, glquake just draws a shaded ball around objects that are emiting +light. Clearing this variable will cause it to properly relight the world +like normal quake, but it can be a significant speed hit on some systems. + +gl_ztrick 0 +Glquake uses a buffering method that avoids clearing the Z buffer, but some +hardware platforms don't like it. If the status bar and console are flashing +every other frame, clear this variable. + +gl_keeptjunctions 0 +If you clear this, glquake will remove colinear vertexes when it reloads the +level. This can give a few percent speedup, but it can leave a couple stray +blinking pixels on the screen. + +novelty features +---------------- +These are some rendering tricks that were easy to do in glquake. They aren't +very robust, but they are pretty cool to look at. + +r_shadows 1 +This causes every object to cast a shadow. + +r_wateralpha 0.7 +This sets the opacity of water textures, so you can see through it in properly +processed maps. 0.3 is very faint, almost like fog. 1 is completely solid +(the default). Unfortunately, the standard quake maps don't contain any +visibility information for seeing past water surfaces, so you can't just play +quake with this turned on. If you just want to see what it looks like, you +can set "r_novis 1", but that will make things go very slow. When I get a +chance, I will probably release some maps that have been processed properly +for this. + +r_mirroralpha 0.3 +This changes one particular texture (the stained glass texture in the EASY +start hall) into a mirror. The value is the opacity of the mirror surface. + diff --git a/contrib/other/sdlquake-1.0.9/glquake.h b/contrib/other/sdlquake-1.0.9/glquake.h new file mode 100644 index 000000000..f3c253c38 --- /dev/null +++ b/contrib/other/sdlquake-1.0.9/glquake.h @@ -0,0 +1,251 @@ +/* +Copyright (C) 1996-1997 Id Software, Inc. + +This program is free software;

The environmental experience of +Quake is unparalleled. Dissolution of Eternity sustains the same dynamic +sense of reality and dramatic visuals; yet adds an impression of purpose +and continuity. This expansion pack is most definitely not a conglomeration +of clone levels! + +8 new monsters! Quake is solid, hard-hitting action with a host of evil +enemies. We've made additions to the Quake monster roster to intensify the +action and fill every dimly lit and evil corner of the game. + +4 new weapons! The Quake weapons are awesome, but we've pushed them beyond +that with the addition of extreme power-ups to make the arsenal more +effective, and more deadly. + +Oh yeah, the Power-Ups! + +Single player mode power-ups include: + +The Anti-Grav Belt. The theory here is simple. It counters the force of +gravity and allows the player to make difficult jumps. + +The Power Shield. This 'little gem' significantly decreases the damage you +receive from most enemy attacks. If you're feelin' frisky in Deathmatch, +try out the ram attack. It's an added 'weapon' to send your opponents flying. + +Deathmatch will introduce the player to: + +The Vengeance Sphere. We'd like you to experience it before we let you in on +what it does. Here's a hint: Ultimate retribution from the grave! + +Random Respawn. This feature will toss in a bit of Deathmatch variety. Hey, +we can't be responsible for what awesome power up 'pops up' next. + +Multi-player! + +Normal Deathmatch. Friend fraggin' action! +Team Play. Bring a friend, to kill a foe. +Tag. You played it as a kid, but nothin' says "Tag!" like a face full of +Plasma. + +And, a much enhanced version of Capture the Flag! +Capture the Flag. You've seen it on the Internet; now it's in your hands. +Additional value, additional excitement, and additional Deathmatch 'down and +dirty' devastation. CTF is one of the most exciting team multi-player +directions for Quake to date; and the most popular too! + +Including two brand new CTF features. + +One Flag - It's a mad race for the flag, the loser gets a rocket up his +privates. +Three Team - Red, Blue, and the new Rogue (pun intended) Grey team. The good +news? You can take either flag and bring to it either Red or Blue base. The +bad news? You don't have your own base! + +Also, a collection of lethal environmental hazards have been placed at every +turn. They are challenging, and terminal! Here are just a few of them. + +The Pendulums - Set to slice the player to shreds when he least expects it! +Lightning Shooters - Well, they shoot lightning and can be directed at any +angle to make some rooms extremely hazardous. +Lava Nail Shooters - Well, they shoot, you get the idea here! +Earthquakes - Earthshaking environments! Level areas that tremor with +seismic activity. Now the Quake player can literally quake! +Buzz Saws - Compact. Cordless. And completely gib-o-matic!

It is designed to take +advantage of whatever enhanced video, sound, and input capabilities +(such as DirectX or VESA VBE video modes) are present, but has +fallback functionality so it can run on any Win95 or NT 4.0 or later +system, even if neither DirectX nor VESA VBE is available. You may +experience problems running WQ on some systems, because driver and +operating-system support for game functionality are not yet mature +under Win32, and many bugs and incompatibilities remain in those +components. If you encounter what seems to be a bug, first please +check through the list of known problems, below. If your problem +doesn't appear on the list, please fill out and submit the WQ bug +report at http://www.idsoftware.com/contact/. + +The material accompanying Quake is the reference for all +non-Windows-related matters concerning WinQuake; in terms of gameplay, +WQ is the same as Quake. This file contains Windows-related +information only. + +The rest of this document is organized as follows: + +Installing and running WinQuake +Common problems and workarounds +A bit about how WQ video works +Video command-line switches +A bit about how WQ sound works +Sound command-line switches +Notes on networking +Notes on the mouse +Log of changes to documentation +Special thanks + + +----------------------------------- +| Installing and running WinQuake | +----------------------------------- + +In order to run WinQuake, you must first have Quake installed. +Assuming Quake is installed in the standard directory, c:\quake, +unzip the WinQuake zip file into c:\quake. The following files +from the zip file must be present in order for WQ to run: + +winquake.exe +pmpro16.dll +pmpro32.dll +wdir16.dll +wdir32.dll +wdirnop.com +wdirnop.pif + +Then you can run WinQuake by making c:\quake the current directory, +typing "winquake" and pressing the Enter key. Alternatively, you can +use wq.bat to run WinQuake. The wq batch file requires one parameter +describing how to configure WQ for performance; just type "wq" to get +a list of the six options. The first of the six options is + +wq fast + +This is the same as typing "winquake"; this runs WinQuake in an +aggressive configuration that is likely to yield the best performance +if it runs successfully on your system, but which has a risk of +causing WinQuake or even your system to crash if there are bugs or +incompatibilities in your video or sound drivers. Alternatively, you +can use + +wq safe + +to run WinQuake in a conservative configuration, likely to run +on almost all machines with no problems, but possibly with slower +graphics, fewer high-resolution modes, and delayed sound. Or you +can run + +wq verysafe + +to run WinQuake in a very conservative configuration that is pretty +much guaranteed to run, but will probably have slow performance, and +will have no sound. Two other options are + +wq fastvid + +which has maximum video performance, but greater sound latency (delay +until the sound is heard), and + +wq fastsnd + +which uses more conservative video modes, but low-latency sound. + +(One odd note is that DirectSound has much lower-latency sound than +wave sound, but is currently quite a bit slower overall. Thus you +may find that "wq fastvid" is actually faster, by as much as 5-10%, +than "wq fast"; however, it may not feel faster, because the sound +will lag.) + +Finally, you can use + +wq max + +which is the same as wq fast, but turns on DirectInput, which +provides more responsive mouse control, but does not work properly +on all systems. + +Note that DirectX is not required for WQ to run, but WQ will +automatically take advantage of DirectSound and DirectDraw if they +are present. If DirectSound is not present, there will generally be +considerable sound latency (sound will become audible several hundred +milliseconds after the event that caused it). Note also that there +are currently no true DirectSound drivers for Windows NT, so WQ will +always run using wave output on NT, and will consequently have lagged +sound. See below for information about obtaining DirectX if you do +not have it. + +Note that VESA VBE modes aren't required for WQ to run, but WQ will +automatically make VESA modes available if they're present. Your BIOS +may already have VESA VBE 2.0 support built in, but most BIOSes +don't. Worse, some BIOSes do have VESA VBE 2.0 built-in, but have +buggy implementations, which may prevent you from being able to run +the faster configurations of WQ. An easy way to get reliable VESA 2.0 +support is by obtaining SciTech Display Doctor; see below for +further information. WQ can also use VBE/AF 1.0 and greater modes; +again, SciTech Display Doctor is the commonest way to get VBE/AF +support. + +Note that winquake -dedicated completely replaces the old winded +dedicated Win32 server, which is now obsolete. + +WinQuake normally uses half the physical memory in your system for its +heap, but not less than 8.5 Mb and not more than 16 Mb. You can +override this with "-heapsize n", where n is the amount of memory to +allocate for the heap, in Kb. + +To use the joystick, you must bring down the console by pressing the +tilde ('~') key, and type "joystick 1"; you can disable the +joystick with "joystick 0" at any time. The joystick setting +remains in effect for subsequent WinQuake sessions until changed, so +you only need to do joystick 1 once to enable the joystick. If the +joystick somehow causes problems that keep you from being able to run +WinQuake at all, you can start WinQuake -nojoy to complete disable the +joystick for that session. + + +----------------------------------- +| Common problems and workarounds | +----------------------------------- + +WQ crashes or won't run +----------------------- + +If WQ refuses to run or crashes on your system, try running +it using "wq safe" or "wq verysafe". Or you can use command-line +switches: + +winquake -nodirectdraw -nowindirect -wavonly + +This will almost certainly solve your problem; however, it may result +in lagged sound (a long delay from action to hearing the sound), may +result in fewer or slower high-res video modes, and the mouse may be +somewhat less responsive. If this does work, you can try removing +each of the command-line switches until you identify the one that +fixes the problem, thereby sacrificing as little functionality as +possible. + +If the above command line does not fix your problems, try: + +winquake -dibonly -nosound + +which forces WQ into silent operation with bare-bones video support +and no use of DirectInput for mouse input (the normal Windows mouse +APIs are used instead). Again, if this works, try removing switches +until you identify the needed one. + +Both of the above command lines are quick fixes. Often, the problem +is caused by outdated or buggy DirectX drivers or code, and can +frequently be completely fixed simply by installing the latest +Microsoft-supplied version of DirectX, which you may be able to find +on http://www.microsoft.com/mediadev/download/directx.exe, although +the availability and location of the DirectX file changes +periodically; note that at last check, this is a 3.4 Mb file. (Be +aware, though, that sometimes Microsoft's DirectX drivers don't +support features that the manufacturers' drivers do support, such as +display refresh rate control.) + +One known problem of this sort involves the current SB16 drivers from +Creative Labs, which cause WQ to crash on some machines. The +DirectSound drivers from Microsoft, available via the above-mentioned +URL, fix this problem. + +It can also sometimes help to get the latest Windows drivers for your +video adapter or sound card (although as the SB16 example indicates, +this is not always a good idea), and for video boards that have flash +BIOSes, it can sometimes help to get the latest BIOS upgrade. + + +How do I select fullscreen or windowed WQ operation? +---------------------------------------------------- +Check out WQ's new, spiffy Video menu, accessible from the Options +menu. There are now two types of modes listed, windowed and +fullscreen. You can make any of these modes the current and/or +default mode, just as in DOS Quake. If you make a windowed mode the +default, WQ will still briefly start up in fullscreen mode, then +switch to windowed; if this is a problem, use the -startwindowed +command-line switch. More complete video control is available +through the console, as described in the "A bit about how WQ video +works" section, below. + + +Gee, I wish I could use a mouse to play WQ with in a window +----------------------------------------------------------- +You can! While in a windowed mode, go to the Options menu. At the +bottom, you'll find a new selection that lets you choose to have the +mouse active when you're in a window. Of course, if you do this, +you'll have to use the keyboard (Alt-Tab, the Windows key, Ctrl-Esc, +Alt-Esc, or Shift-Alt-Tab) to switch away from WQ. + + +Serial/modem menu is missing +---------------------------- +WQ currently does not support direct connect serial or modem play. + + +DOS Quake reports unknown variables on startup after running WQ +--------------------------------------------------------------- +WQ uses some console variables that do not exist in DOS Quake, and +some of these are automatically archived in config.cfg when you exit +WQ. If you then start DOS Quake, DOS Quake will complain that it +doesn't recognize those variables. You will also lose the settings +of these variables when you return to WQ. Apart from losing the +settings, this is harmless; ignore it. + + +Problems running WQ on NT 3.51 +------------------------------ +NT 3.51 isn't supported by WQ. + + +WQ crashes while switching modes or Alt-Tabbing +----------------------------------------------- +So far, all cases of this seem to be tied to Creative Lab's SB16 sound +drivers, and have been fixed by getting the latest DirectX drivers, as +described above. Alternatively, you should be able to fix this either +by not switching modes or Alt-Tabbing, or by running -wavonly to +disable DirectSound support. + + +WQ sometimes runs pretty slowly fullscreen +------------------------------------------ +There are several possible reasons for this, starting with "You have a +slow computer." Assuming that's not the case, if you don't have +either DirectDraw or SciTech Display Doctor installed (see the "A bit +about how WQ video works" section), it would probably be a good thing +to install one or the other, because slow operation can be a result +of slow copying or stretching of pixels to the screen by a Windows +driver, something that's eliminated by both DirectDraw and Display +Doctor. You can also sometimes get a faster 320x200 mode on Win95 by +doing vid_describemodes, then using vid_mode to select a non-VGA +320x200 mode, as described in the "A bit about how WQ video works" +section. + +You can also try using a primary sound buffer on Win95 (this doesn't +work on NT) by using the -primarysound command-line switch; this can +improve performance by several percent, but does not work on all +systems, and can result in odd sound effects on some systems when +minimizing WQ or switching the focus away from it. If you use this +switch, please don't report sound bugs; it's in there purely for you +to use if it helps you, and we know it has problems on many systems. +Finally, you can use -wavonly to select wave sound; this will increase +your sound latency (sounds will be heard later than they should), but +allows WQ to run 5-10% faster on some systems. That's about all you +can do to speed up fullscreen WQ on Win95, other than shrinking the +active area of the screen with the screen size control in the Options +menu. + +NT 4.0 comes with DirectX installed, but doesn't have any resolutions +lower than 640x480. In order to support a lower-resolution 320x240 +mode, WQ has NT double each pixel in both directions to get enough +pixels for 640x480. The extra stretching costs some performance, the +result being that NT can seem sluggish on all but high-end Pentiums +and Pentium Pros. (In fact, depending on the quality of your driver's +stretching code, it can sometimes be faster to run WQ at 640x480 than +320x240-stretched on NT.) One thing that can help on NT is switching +to 640x480, then using the Options menu to shrink the active area of +the screen. + +A common cause of slowness running in a window is having the desktop +run in 16- or 32-bpp mode. WQ is an 8-bpp application, and it slows +things down if pixels have to be translated from 8-bpp to 16- or +32-bpp. (Note that this is generally a problem only when running in a +window; fullscreen apps rarely suffer from this.) + + +Sound is sluggish on NT +----------------------- +NT doesn't have any real DirectSound drivers yet, so there's no way to +do quick-response sound on NT. When DirectSound drivers for NT +appear, WQ's sound should automatically be snappier. + + +Sound breaks up or gets choppy, especially in menus +--------------------------------------------------- +This is generally a sign that WQ's frame rate is too low on your +system. Try reducing resolution or shrinking the active area of the +screen. In some circumstances, it may help to set the console +variable _snd_mixahead to a larger value. + + +The color black doesn't change with palette flashes sometimes +------------------------------------------------------------- +Normally, DirectDraw lets WQ change all 256 colors, so when a palette +flash happens, we can change all the colors, including black. +However, on NT DirectDraw currently doesn't allow changing black; +likewise, on both NT and Win95, black can't be changed in a window, +either a normal window or fullscreen. Consequently, in some modes and +in a window, some parts of the WQ screen (such as the sigils on the +status bar and the spray where a shotgun blast hits) stay black when +the palette flashes. There is no workaround. + + +Problems can result if Office shortcut bar is running +----------------------------------------------------- +Various odd behaviors, especially with sound, have been reported if +the Office shortcut bar is running while WQ is running. If you +experience odd problems, you might try shutting down the Office +shortcut bar and see if that fixes anything. + + +Other apps fail to play sound while WinQuake is running +------------------------------------------------------- +The sound hardware is currently not a fully shareable resource on +Win32. Consequently, while WQ is running, it always has the sound +hardware allocated to itself, to make sure that sound is never lost to +another app. This means that normally (when WQ is using DirectSound), +apps that use wave sound (most non-game apps) will not be able to play +sound while WQ is running, even if WQ is minimized or not the active +app, although other DirectSound apps will be able to play sound when +WQ is not the active app. If WQ is using wave sound rather than +DirectSound (either because -wavonly is used on the command line, or +because there is no DirectSound driver, as is always the case on NT), +then no other app will be able to play any sound while WQ is running, +period. + + +WQ doesn't have quite the right colors when it’s not the active app +------------------------------------------------------------------- +We're working on fixing this. But WQ puts everything back again as +soon as it is reactivated, and anyway, when it’s not active, you can’t +actually do anything in WQ, so it doesn’t really matter anyway, right? + + +Desktop is weird colors when WQ runs windowed +--------------------------------------------- +WQ needs all 256 colors to look right and run fast, which causes it to +have to change some of the 20 colors used to draw the desktop. + + +Sometimes Permedia boards crash unless -nowindirect is used +----------------------------------------------------------- +It looks like this is probably a Permedia driver bug, so it might help +if you get the most recent drivers. + + +Right-click on WQ button in task bar to close doesn’t work as expected +---------------------------------------------------------------------- +In some modes, right-clicking on the WQ task bar button doesn't work +the way you'd expect. We're trying to fix this, but if it's a +problem, don't right-click. + + +Screen saver never kicks in when running WQ fullscreen +------------------------------------------------------ +It does work windowed, but when WinQuake is fullscreen, it completely +owns the screen and doesn't share it with anyone, even the +screensaver. If you use Alt-Tab to minimize WQ, the screensaver will +then be enabled, so Alt-Tab away from WQ if you're leaving your +computer alone for a while and want the screensaver to be able to kick +in. + + +WQ doesn’t work in a window in 16-color mode +-------------------------------------------- +That’s 16 *colors*, not 16-bpp. If you’re still running a 16-color +desktop, run WQ fullscreen. + + +Can't minimize window while mouse active +---------------------------------------- +When running in a window with the mouse active as a WQ input device, +there is no easy way to minimize the window, because the system menu +can't be brought up from the keyboard (because some of you use Alt +and Spacebar for playing the game), and the mouse can't be used to +manipulate the window because it's controlling WQ. To minimize, you +can disable the mouse for WQ and use it to minimize the window. Or +on Win95 you can Alt-Tab away from WQ, then use the mouse to +minimize (this doesn't work on NT, where clicking on the window +controls just reactivates WQ). Or you can bind a key to the +vid_minimize command, as in + +bind m "vid_minimize" + +and press that key to minimize the window. + + +Window controls don't work on NT when mouse enabled +--------------------------------------------------- +When running in a window on NT with the mouse enabled (so you can use +the mouse to play WQ), if you Alt-Tab away from WQ, then use the mouse +to click on the WQ system menu control, or the minimize, maximize, or +close controls, the controls are ignored and WQ just reactivates. + + +Mouse sometimes vanishes in system menu on Win95 +------------------------------------------------ +On Win95, if WQ is running in a window with the mouse enabled (so you +can use the mouse to play WQ), if you Alt-Tab away, then click on the +system menu, the menu comes up, but the mouse vanishes. However, you +can still use the keyboard to select system menu items, or to exit +the system menu. + + +WQ behaves oddly if Scandisk starts defragmenting +------------------------------------------------- +If WQ is running fullscreen on Win95 when Scandisk starts an automatic +defragging, WQ is forced to minimize, and when it is brought back up, +may either be in a strange mode where it runs one frame for each +keystroke (in which case Alt-Tab generally fixes things), or may hang +the system. We don't know what the problem is right now, but you may +want to make sure you don't leave WQ sitting there fullscreen +overnight if you have automatic defragging. + + +Hang reported with zero sound volume +------------------------------------ +When sound is turned all the way down via the WQ menus, hangs have +been reported. + + +Joystick worked fine with earlier versions of WinQuake but not now +------------------------------------------------------------------ +The joystick was enabled by default in earlier versions of +WinQuake, but quite a few people reported serious problems that +forced them to disable the joystick--even some people who didn't +have a joystick attached. Since most people don't have joysticks, +we've decided to disable the joystick by default, and let people +who do want to use it set joystick 1 in the console (WinQuake +remembers this setting, so this only needs to be done once). + + +WQ runs very slowly when it has the focus under NT +-------------------------------------------------- +In one case, WQ ran very slowly when it had the focus, but fast when +it didn't (obviously this is only visible in windowed modes). The +problem turned out to be that NT had a Sidewinder 3D Pro joystick +driver installed; when the driver was removed, things were fine. +If you see a similar problem, check whether WQ is detecting that +your system has a joystick when you don't think it should; if so, +try doing "joystick 0", or -nojoy on the command line, and see if +that fixes it. If so, there's something flaky in your system +joystick setup. + + +Joystick doesn't seem calibrated properly +----------------------------------------- +WQ relies on the information about your joystick stored in the +system registry. If the joystick seems miscalibrated, run the +joystick applet and recalibrate and see if that fixes things. + + +Playdemo fails across multiple levels +------------------------------------- +If "record" is used to record a client-side demo, bad things will +happen on playback via playdemo if a level change is recorded. +(Timedemo works fine.) This is unfortunate, but WinQuake +internals make this not fixable without a good chance of +breaking something more important, so it'll have to stay this way. + + +Alt-Tab fullscreen only works sometimes +--------------------------------------- +I know it seems that way, but actually the trick is that on Win95 +it only works if you let go of Tab before you let go of Alt. +This is due to a Windows quirk involving what key sequences are +passed along, so you'll have to work around it by remembering to +let go of Tab first. + + +MS-DOS windows get scrunched on Alt-Tab +--------------------------------------- +This is a quirk of Windows; when you run WinQuake in a low-res +mode, sometimes when you exit WinQuake or Alt-Tab back to the +desktop, any open MS-DOS windows will be scrunched down to the +size of the low-res mode. There is no known workaround. + + +Dprint in progs doesn't work +---------------------------- +Dprint means "developer print," so it only works if the developer +console variable is set to 1. It was a bug in earlier versions that +it worked even when developer was set to 0. + + +Some DirectDraw modes flicker badly and look wrong +-------------------------------------------------- +Page flipping doesn't work properly in some modes on some +systems, particularly when using some DirectDraw modes. You +can work around this by setting the console variable +vid_nopageflip to 1, then setting the desired mode (note +that the vid_nopageflip setting does not take effect until +the next mode set after the setting is changed). Bear in +mind, though, that the vid_nopageflip setting is remembered +until it is explicitly changed again, meaning that once you +change it, it thereafter applies to all modes, even if you +exit and restart WinQuake. + + +The Windows key doesn't do anything fullscreen on Win95 +------------------------------------------------------- +True. This is a minor bug we haven't figured out how to fix yet. +You'll have to use Ctrl-Esc, Alt-Tab, or Alt-Esc to switch away. + + +My default mode is windowed, but WQ goes fullscreen first +--------------------------------------------------------- +For internal reasons, WQ has to pick a single mode to always +initialize when it starts up, before it sets whatever default you've +selected. We've chosen fullscreen mode, because that's the way most +people will play. If this is a problem for you, however, you can +run WQ with the -startwindowed command-line parameter. + + +Some high-resolution video modes flicker or fail to initialize +-------------------------------------------------------------- +We think these problems are all fixed, but if not, they have to +do with triple-buffering in some modes on some DirectDraw drivers. +If you encounter this problem, either don't use the problem modes +or try using the -notriplebuf command-line parameter to turn off +triple buffering. Note, though, that turning off triple-buffering +can reduce performance in some modes, so do this only if needed. + + +Right-click doesn't work right on minimized WinQuake +---------------------------------------------------- +If you right-click on minimized WinQuake on the task bar, the +Close selection in the right-click menu doesn't work; you have +to restore WQ before you can exit it. Also, the cursor vanishes +over the right-click menu, although it still works. + + +The screen briefly blanks when you exit WQ +------------------------------------------ +We're trying to fix this, but it's not harmful, just a mite ugly. + + +QBENCH doesn't work with WinQuake +--------------------------------- +We've had a report that QBENCH doesn't work with WinQuake, but +haven't had a chance to look into it yet. + + +MWAVE sound loses focus +----------------------- +We've had a report that on a ThinkPad with MWAVE sound, WQ loses +sound focus (and thus sound) every few seconds. + + +Desktop doesn't reset to proper resolution on WQ exit +----------------------------------------------------- +We've had a report that on exiting WQ, the desktop didn't reset +to the proper dimensions. This may be a bug with the Matrox +drivers, but we're not sure. If it's a problem and newer +drivers don't fix it, you can run -dibonly, which solves the +problem but can cost some performance. + + +Palette goes bad periodically on #9 Imagine card +------------------------------------------------ +There's only one report of this, so maybe it's a flaky board, +or maybe it's a driver bug. Newer drivers might help. + + +System with Packard Bell sound card III crashes on CapsLock +----------------------------------------------------------- +This appears to be the result of buggy DirectSound drivers; +-wavonly makes the problem go away. + + +Dvorak keyboard mapping ignored +------------------------------- +WQ is hardwired for QWERTY. + + +Cursor messed up after running WQ +--------------------------------- +This is a Windows driver bug; the driver isn't restoring the +cursor properly on return from fullscreen WQ to the desktop. +Try newer drivers. + + +Dedicated server runs very slowly while typing at console +--------------------------------------------------------- +When you type at a dedicated server's console, the game runs +very slowly for everyone who's connected. + + +Ctrl-Alt-Del on NT sometimes doesn't allow return to WQ +------------------------------------------------------- +This happens on some machines while running WQ fullscreen. +If you experience this problem, the only workaround is not +to press Ctrl-Alt-Del while fullscreen; Alt-Tab away first. + + +Many fast Alt-Tabs on Win95 sometimes disable WQ input +------------------------------------------------------ +If you Alt-Tab fast lots of times on Win95 with WQ running +fullscreen, sometimes you end up in fullscreen WQ, with the +game not accepting any keyboard input (so there's no way to +exit). The only workaround is to not do lots of fast +Alt-Tabs (why you'd want to, I'm not sure). + + + +---------------------------------- +| A bit about how WQ video works | +---------------------------------- + +WQ has the built-in ability to draw into windows (both normal, framed +desktop windows and fullscreen, borderless windows). It also has +built- in support for VGA 320x200 graphics, and supports DirectDraw, +VESA VBE 2.0 and VESA VBE/AF (Accelerator Functions) graphics modes, +if those are available. + +WQ does not require DirectDraw, but in order for DirectDraw modes to +be available, you must have DirectDraw installed; some systems come +with it preinstalled, but if it's not on your system, you can download +it from http://www.microsoft.com/mediadev/download/directx.exe (the +exact URL may vary), and install it. + +WQ does not require VESA VBE, but in order for VESA VBE modes to be +available, your graphics card must be VESA VBE 2.0 or VBE/AF +compliant; a VESA driver can either be built into the BIOS of your +graphics card, or loadable via software. If you don't have a VESA VBE +driver, Scitech Display Doctor, available from Scitech Software, will +update most graphics cards to VESA VBE 2.0 and VBE/AF. + + +SciTech Display Doctor +---------------------- +If you are having problems with your video drivers, or if you would +like to take a shot at improving your video performance in WQ, you may +want to try out SciTech Display Doctor (SDD). SDD works on just about +any graphics card and it can do several things that can make WQ run +better on your system: + +1. It will update your graphics card to be compatible with VESA VBE +2.0 and VESA VBE/AF (Accelerator Functions). These modes will usually +give you the best performance in WQ (which is often but not always +faster than your current performance). + +2. It creates low-resolution modes on your graphics card. +Low-resolution video modes (such as 320x240, 400x300 and 512x384) +allow you to adjust the level of detail in WQ so you can get the best +balance between performance and image quality. + +The latest version of SciTech Display Doctor can be obtained from the +following locations: + +www: http://www.scitechsoft.com +ftp: ftp.scitechsoft.com +CIS: GO SCITECH +AOL: Keyword SciTech + +SciTech can be contacted at: + +email: info@scitechsoft.com + +SciTech Software, Inc. +505 Wall Street +Chico, CA 95926-1989 +916-894-8400 +916-894-9069 FAX + + +Video modes supported in Win95 +------------------------------ +What all this means is that on Win95, WQ will always be able to run in +the following modes: + +1) in a window +2) fullscreen 320x200 VGA mode 0x13 +3) fullscreen high-resolution of some sort + +Category #3 can be any of several configurations. On Win95, if either +DirectDraw or VESA VBE modes are available, then all the DirectDraw +and VESA modes will be presented as high-res choices. (320x200 will +always default to VGA mode 0x13.) In the case that a given resolution +is supported by both DirectDraw and VESA, the VESA mode will be used. +(However, the command-line switch -nowindirect can turn off VESA modes +entirely.) If neither DirectDraw nor VESA modes are available, then +high-resolution modes will be provided by using fullscreen, borderless +windows in whatever resolutions the Windows driver supports, usually +starting at 640x480 and going up. + + +Video Modes Supported in Windows NT +----------------------------------- +NT is similar but not identical, because neither VESA VBE modes nor +VGA mode 0x13 are available. On NT, WQ will always be able to run in +the following modes: + +1) in a window +2) fullscreen high-resolution of some sort + +On NT, category #2 can be one of two configurations. If DirectDraw +modes are available, then those will be the high-res choices; +otherwise, fullscreen, borderless windows will be used in whatever +resolutions the driver supports, usually starting at 640x480 and going +up. Because there is normally no low-resolution mode such as 320x200 +or 320x240 on NT, a pseudo low-res mode is created by rendering at +320x240, then stretching the image by doubling it in each direction +while copying it to a 640x480 screen. However, stretching performance +depends on the driver, and can be slow, so sometimes 640x480 is +actually faster than 320x240 on NT. + +The bottom line here is that you can generally just use the Video menu +and pick one of the modes and be happy. In some cases, though, you +may need to use command-line switches (described next) to get the +types of modes you want. One useful tip is to go into the console and +do vid_describemodes, which lists all the modes WQ makes available on +your machine given the command-line switches you've used. Each mode +is followed by the name of the internal WQ driver that supports it, so +you can tell which modes are DirectDraw, VESA, and so on, as follows: + +WINDOWED: WQ runs in a normal window +FULLSCREEN DIB: fullscreen borderless window +FULLSCREEN VGA8.DRV: VGA 320x200 mode +FULLSCREEN DDRAW8.DRV: DirectDraw mode +FULLSCREEN LINEAR8.DRV: VESA VBE 2.0+ mode +FULLSCREEN ACCEL8.DRV: VESA VBE/AF (Accelerator Functions) mode + (note that WQ does not take advantage of + VBE/AF acceleration; so far as WQ is + concerned VBE/AF is the same as normal VBE) + +You can use vid_mode from the console to set any of these modes. So, +for example, if you see that there are two 320x200 modes (such as one +VGA mode 0x13, normally mode 3, and one VESA mode, normally mode 4), +you can choose the VESA mode, which will often be faster, with +vid_mode 4. (You can make it the default by setting +_vid_default_mode_win to the mode number.) + +There's more to the windowed modes than you might think. 320x240 is +just what you’d expect, but 640x480 is actually rendered at 320x240 +and stretched up to 640x480, because most machines can’t handle the +performance demands of real 640x480 rendering. Likewise, 800x600 is a +stretched 400x300. Actually, though, vid_mode 2 (the 800x600 mode) is +a user-configurable mode. By setting the following console variables, +you can change the characteristics of vid_mode 2: + +vid_config_x: width of mode 2 window + +vid_config_y: height of mode 2 window + +vid_stretch_by_2: whether to render at half-resolution in each +direction and stretch up to the specified size in mode 2, or render at +full resolution. + +After setting these variables in the console, do a vid_forcemode 2, +and you’ll have the window you specified. Note that after making +these changes, the new resolution will show up as the third windowed +mode in the Video menu. + +If you don't have WQ mouse play enabled in windowed mode, you can also +go from windowed to fullscreen mode simply by clicking on the maximize +button. The mode switched to is controlled by the vid_fullscreen_mode +console variable, and defaults to mode 3. + +Other video console commands include: + +vid_fullscreen: switch to the mode specified by the +vid_fullscreen_mode console variable. + +vid_windowed: switch to the mode specified by the vid_windowed_mode +console variable. + +Vid_fullscreen and vid_windowed can be bound to keys, so it's possible +to flip between windowed and fullscreen with a single key press. + +Also, vid_minimize minimizes the WinQuake window if and only if +WinQuake is running in a windowed mode. You can bind a key to +the commands "vid_windowed; wait; vid_minimize" to minimize WQ +regardless of whether you're running in windowed or fullscreen mode. + +You can turn off page flipping by setting the console variable +vid_nopageflip to 1, then setting a new mode. (Note that the +vid_nopageflip setting does not take effect until the next mode set.) +Some systems run faster with page flipping turned off; also, page +flipping does not work properly on some adapters, and vid_nopageflip +is a workaround for this. Note that vid_nopageflip is a persistent +variable; it retains its setting until it is explicitly changed again, +even across multiple WinQuake sessions. + +The vid_forcemode console command sets the specified mode, even if +it's the same as the current mode (normally the mode set only happens +if the new mode differs from the current mode). This is generally +useful only if you've modified the characteristics of video mode 2 +(the configurable window) while you're in mode 2, and want to force +the new characteristics to take effect. + +Whenever you switch to running WinQuake in a window, the window is +placed at the same location it was in the last time WinQuake ran +in a window. You can reset the window position to the upper left +by using the -resetwinpos command-line switch. The window position +is stored in the vid_window_x and vid_window_y console variables. + + + +------------------------------- +| Video command-line switches | +------------------------------- + +The full list of video-related command-line switches is: + +-dibonly: WQ will use only windows (both normal, framed windows on the +desktop and fullscreen, borderless windows), not any direct hardware +access modes such as DirectDraw or VESA modes, or even VGA 320x200 +mode. This is the closest thing to a guaranteed-to-run fullscreen +mode WQ has. + +-nowindirect: WQ will not try to use VESA VBE 2.0 modes, or VBE/AF +1.0 or later modes. Note that if there are both DirectDraw and VESA +modes for a given resolution, WQ will normally use the VESA mode; +-nowindirect allows DirectDraw modes to be the preferred choice for +all resolutions except 320x200. This can be useful if WQ is crashing +because of a buggy VESA driver. + +-nodirectdraw: WQ will not try to use DirectDraw modes. This can be +useful if WQ is crashing because of a buggy DirectDraw driver. + +-novbeaf: WQ will not try to use VBE/AF 1.0 or later modes. + +-startwindowed: WQ will come up in a windowed mode, without going +fullscreen even during initialization. + +-noforcevga: normally, WQ uses VGA mode 0x13 for the default 320x200 +mode, even if a DirectDraw or VESA 320x200 mode exists. However, +DirectDraw and VESA modes can be considerably faster than mode 0x13, +because they can set up a linear framebuffer with higher memory +bandwidth. If you specify -noforcevga, the default 320x200 mode in +the menu will be a DirectDraw or VESA mode if one exists. This has no +effect on modes selected via the console variable vid_mode, and if +320x200 is already your video mode, -noforcevga doesn't do anything +until you use the menu to select another mode, then select 320x200 +again. (So if your default mode is 320x200 and you then specify +-noforcevga, switch away to some other mode and then back to 320x200 +to get the potentially faster 320x200 mode.) The downside to this +switch is that DirectDraw and VESA modes can cause problems in some +systems, due to driver bugs or hardware incompatibilities; if you +experience problems with this switch, don't use it. + +-noautostretch: don't stretch windowed modes selected with +-startwindowed to double resolution. + +-nofulldib: don't use fullscreen, borderless windows, even if there +are no DirectDraw or VESA modes available. + +-allow360: allow listing of 360-wide modes in the video mode menu. +These are normally filtered out to make sure the menu doesn't get too +full, which could cause high-res modes not to be displayed. + +-notriplebuf: prevent triple-buffered page flipping (rather than double- +buffered). This may result in slower performance, but is a workaround +if you encounter problems with flicker or initialization failure, which +could possibly happen in some modes with some DirectDraw drivers. + + + +---------------------------------- +| A bit about how WQ sound works | +---------------------------------- + +WQ can use either DirectSound or Windows wave output to generate +sound. If DirectSound is available, it is used; if not, if wave sound +is available it is used; and if neither is available, there is no +sound. DirectSound results in the best sound quality, and also the +lowest-latency sound; use it if you can, because you will be happier +with the results. (Note, though, that no NT sound drivers yet support +DirectSound.) Wave sound will often have high latency, lagging the +events that generate sound by hundreds of milliseconds on some +machines. + +You can tell what kind of sound WQ uses on your system by looking at +the startup portion of the console; you will see either "DirectSound +initialized" or "Wave sound initialized" (neither message is printed +if there's no sound). Any sound failure messages will also be printed +in the startup portion of the console. + +Note that WQ generates sound only when it is the active app, the one +with the input focus. + + + +------------------------------- +| Sound command-line switches | +------------------------------- + +The full list of sound-related command-line switches is: + +-wavonly: don’t use DirectSound, but use wave sound if available. +Note that wave sound is generally faster than DirectSound, but has +considerably greater latency. This switch is redundant on NT, because +all sound output on current NT drivers is wave sound. + +-nosound: don’t output any sound. + +-primarysound: use DirectSound primary buffer output. This is +generally faster than normal secondary buffer output, but does not +work in some systems, and produces odd sound glitches on minimization +and focus switching in other systems. Use it at your own risk, and +please do not report sound bugs if you're using this switch. + +-snoforceformat: WQ will not try to force the sound hardware to 11 +KHz, 16 bits per sample. This may be useful if DirectSound is failing +for no apparent reason, but generally WQ will produce better sound and +better performance if this switch is not used. + + + +----------------------- +| Notes on networking | +----------------------- + +The winsock TCP/IP driver will not cause a dial-up internet connection +to automatically start up when Quake is started. If you start Quake +with it inactive, the connection will be activated when you either try +to connect to a server or search for local servers. + +The local IP address will not always be known at startup. If it is +currently unknown the menu will display "INADDR_ANY". This will be +replaced with the real address when it is known. The IP address will +become known when you try to connect to a server, you search for local +servers, or you start a server. + +For multi-homed machines (machines with more than one network adapter +and IP adress), you can force WinQuake to bind to a specific IP +address. There is a command line option "-ip" that takes an IP +address as its parameter. + + + +---------------------- +| Notes on the mouse | +---------------------- + +If DirectInput is installed and functioning, WinQuake can use it for +mouse input, but does not do so automatically because DirectInput does +not work properly on all systems. DirectInput can be enabled via the +command-line switch -dinput. If DirectInput is not available or is +not enabled, WinQuake uses the normal Windows mouse APIs instead. +DirectInput provides slightly smoother motion; also, it tends to be +more responsive to fast spinning motions, and we recommend that you use +it if it works properly on your system. You can determine if WQ uses +DirectInput on your system when you use -dinput by checking for +"DirectInput initialized" in the startup console text. If not, you +might try installing DirectX 3 (note, though, that as I write this +there is no released DirectInput support for Windows NT, only Win95). + + + +----------------------------------- +| Log of changes to documentation | +----------------------------------- + +*** WinQuake 0.994 *** + +Fixed bug where in some cases involving IPX, whenever a new person +entered the game, a current player got dumped. + +Added DirectInput mouse support, and the -dinput command-line to +enable it. + +Added -notriplebuf to disable triple buffering to work around +possible problems with some modes on some DirectDraw drivers. + +Added remembering last window position, and restoring that, rather +than centering the window, whenever WinQuake runs in a window. +Can be reset with the -resetwinpos command-line switch. + +Added the vid_minimize command, which minimizes WinQuake if and only +if the current mode is windowed. + +Made it so WinQuake no longer gets suspended when Alt-Tab is used to +switch away from a fullscreen session. The means you can Alt-Tab +away from fullscreen WinQuake without losing a connection to a +Quake server. + +Added vid_nopageflip console variable to turn off page flipping, and +documented page flipping problems this can be used to work around. + +Documented that Del-Ctrl-Alt (in that order) causes WinQuake to +fault on Win95. + +Fixed the winsock TCP/IP driver so it will not cause a dial-up +internet connection to automatically start up when Quake is started. +If you start Quake with the internet connection already active, there +will be no difference. If you start Quake with it inactive, the +connection will be activated when you either try to connect to a +server or search for local servers. + +The local IP address will not always be known at startup now. If it +is currently unknown the menu will display "INADDR_ANY". This +will be replaced with the real address when it is known. The IP +address will become known when: you try to connect to a server, +you search for local servers, or you start a server. + +For multi-homed machines (machines with more than one network +adapter and IP adress), you can now force WinQuake to bind to a +specific IP adress. There is a new command line option "-ip" that +takes an IP address as its parameter. + +Added vid_fullscreen_mode and ability to select that mode by +clicking on the maximize button. Added two commands: +vid_fullscreen to switch to vid_fullscreen_mode, and +vid_windowed to switch to vid_windowed mode. + +Changed joystick default to disabled; now it only works if the +joystick cvar is set to 1; however, this setting now remains in +effect permanently. Added joystick documentation below. + +Documented dprint only works if developer set to 1. + +Documented scrunching of MS-DOS windows on Alt-Tab. + +Documented that NT versions earlier to 4.0 are not supported. + +Added DirectInput support for devices such as First Person +Gaming's Assassin controller. All buttons should now +be configurable in WinQuake. + +Fixed bug where when low-res fullscreen DIB modes selected from +the menu sometimes ran very slowly or produced garbled displays. + +Fixed bug where 1.06 and earlier save files couldn't be loaded +by WinQuake. + +Removed "Net play pauses every few seconds" bug; it was determined +not to be a bug, just an artifact of network play. + +Noted that even when BIOSes do have VESA 2.0 built-in, it's often +so buggy that WinQuake crashes in faster configurations, and that +SciTech Display Doctor is the easiest way to get reliable VESA +support. + +Added note on Alt-Tab only working if Tab released first. + + +*** WinQuake 0.992 *** + +Implemented force_centerview. + +Fixed backspace bug in dedicated console. + +Made "player entering game" messages and "say" messages visible +in dedicated console. + +Added description of -heapsize (how to change default memory +allocation). + +Added description of "net play pauses every few seconds" bug. + +Added description of "playdemo fails across multiple levels" bug. + +Added hooks for QHost; however, WinQuake won't work with QHost +until a new version of QHost 3.0, which uses the hooks, is +released. QHost 3.0 will not work with WinQuake. + +Fixed bug where savegame descriptions weren't always terminated +properly. + +Fixed bug where running -dedicated reset part of config.cfg to +defaults. + + +*** WinQuake 0.991 *** + +Fixed problem with pre-1.07 (DOS) clients connecting to WinQuake. + +Got rid of "Starting Quake..." dialog when running -dedicated. + +Added -novbeaf switch to turn off VBE/AF support in case of problems, +and updated documentation. + +Corrected SciTech's U.S. Mail address in documentation. + +Added joystick bug decriptions and workarounds. + + + +------------------ +| Special thanks | +------------------ + +Special thanks for help with WinQuake to: + +James Barnes +Kendall Bennett +Raymond Chen +John Colleran +Andrew Goossen +Mike Harrington +Chris Hecker +Todd Laney +Scott Ludwig +...and all the beta testers! + +====================================================================== +End of Document 3/21/97 +====================================================================== diff --git a/contrib/other/sdlquake-1.0.9/zone.c b/contrib/other/sdlquake-1.0.9/zone.c new file mode 100644 index 000000000..e30d7f847 --- /dev/null +++ b/contrib/other/sdlquake-1.0.9/zone.c @@ -0,0 +1,935 @@ +/* +Copyright (C) 1996-1997 Id Software, Inc. + +This program is free software;

It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if +you distribute copies of the library, or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link a program with the library, you must provide +complete object files to the recipients so that they can relink them +with the library, after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + c) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + d) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15.

It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile the package for one architecture at a time +in the source code directory. After you have installed the package for +one architecture, use `make distclean' before reconfiguring for another +architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. diff --git a/contrib/sdk/sources/SDL-1.2.2/SDL_draw/Makefile b/contrib/sdk/sources/SDL-1.2.2/SDL_draw/Makefile new file mode 100644 index 000000000..e1f64d2cb --- /dev/null +++ b/contrib/sdk/sources/SDL-1.2.2/SDL_draw/Makefile @@ -0,0 +1,5 @@ +OUTFILE = ../lib/libSDLdraw.a +OBJS = src/SDL_draw.o +CFLAGS = -Iinclude -I. -I../include + +include $(MENUETDEV)/makefiles/Makefile_for_lib diff --git a/contrib/sdk/sources/SDL-1.2.2/SDL_draw/NEWS b/contrib/sdk/sources/SDL-1.2.2/SDL_draw/NEWS new file mode 100644 index 000000000..e69de29bb diff --git a/contrib/sdk/sources/SDL-1.2.2/SDL_draw/README b/contrib/sdk/sources/SDL-1.2.2/SDL_draw/README new file mode 100644 index 000000000..10ff8a50f --- /dev/null +++ b/contrib/sdk/sources/SDL-1.2.2/SDL_draw/README @@ -0,0 +1,117 @@ + +SDL_draw 1.2.1 +~~~~~~~~~~~~~~ +The latest version of this library is available from: +http://sdl-draw.sourceforge.net/ + +This is a simple library to draw basic elements, like points, lines and +circles, on SDL surfaces. + +Library API +~~~~~~~~~~~ +#include "SDL_draw.h" + +//IMPORTANT: Call this function AFTER the call to 'SDL_SetVideoMode': +Draw_Init(); //Register the functions for current bpp + + +void Draw_Pixel(SDL_Surface *super, + Sint16 x, Sint16 y, Uint32 color); + + Draw a colored pixel on coordinates x,y. + + +void Draw_Line(SDL_Surface *super, + Sint16 x1, Sint16 y1, Sint16 x2, Sint16 y2, + Uint32 color); + + Draw a line from x1,y1 to x2,y2. + + +void Draw_Circle(SDL_Surface *super, + Sint16 x0, Sint16 y0, Uint16 r, + Uint32 color); + + Draw a circle with center x0,y0 and radius r. + + +void Draw_FillCircle(SDL_Surface *super, + Sint16 x0, Sint16 y0, Uint16 r, + Uint32 color); + + Draw a filled circle with center x0,y0 and radius r. + + +void Draw_HLine(SDL_Surface *super, + Sint16 x0,Sint16 y0, Sint16 x1, + Uint32 color); + + Draw a horizontal line from x0,y0 to x1,y0. + + +void Draw_VLine(SDL_Surface *super, + Sint16 x0,Sint16 y0, Sint16 y1, + Uint32 color); + + Draw a vertical line from x0,y0 to x0,y1. + + +void Draw_Rect(SDL_Surface *super, + Sint16 x,Sint16 y, Uint16 w,Uint16 h, + Uint32 color); + + Draw a rectangle with upper left corner in x,y being w the width and h the + height. + + +void Draw_FillRect(SDL_Surface *super, + Sint16 x,Sint16 y, Uint16 w,Uint16 h, + Uint32 color); + + The same as above but the rectangle is filled.

And you must show them these terms so they know their rights. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + c) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + d) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS diff --git a/contrib/sdk/sources/SDL-1.2.2/SDL_ttf/Makefile b/contrib/sdk/sources/SDL-1.2.2/SDL_ttf/Makefile new file mode 100644 index 000000000..2ef74ae0c --- /dev/null +++ b/contrib/sdk/sources/SDL-1.2.2/SDL_ttf/Makefile @@ -0,0 +1,5 @@ +OUTFILE = ../lib/libSDL_ttf.a +OBJS = SDL_ttf.o +CFLAGS = -I../include + +include $(MENUETDEV)/makefiles/Makefile_for_lib diff --git a/contrib/sdk/sources/SDL-1.2.2/SDL_ttf/README b/contrib/sdk/sources/SDL-1.2.2/SDL_ttf/README new file mode 100644 index 000000000..9b19de3cc --- /dev/null +++ b/contrib/sdk/sources/SDL-1.2.2/SDL_ttf/README @@ -0,0 +1,27 @@ + +This library is a wrapper around the excellent FreeType 1.2 library, +available at: + http://www.freetype.org/ + +WARNING: There may be patent issues with using the FreeType library. +Check the FreeType website for up-to-date details. + +This library allows you to use TrueType fonts to render text in SDL +applications. + +To make the library, first install the FreeType library, then type +'make' to build the SDL truetype library and 'make all' to build +the demo application. + +Be careful when including fonts with your application, as many of them +are copyrighted.

Sound on the computer is translated from waves that you hear into a series of +values, or samples, each representing the amplitude of the wave. When these +samples are sent in a stream to a sound card, an approximation of the original +wave can be recreated. The more bits used to represent the amplitude, and the +greater frequency these samples are gathered, the closer the approximated +sound is to the original, and the better the quality of sound.

This library supports both 8 and 16 bit signed and unsigned sound samples, +at frequencies ranging from 11025 Hz to 44100 Hz, depending on the +underlying hardware. If the hardware doesn't support the desired audio +format or frequency, it can be emulated if desired (See +SDL_OpenAudio())

A commonly supported audio format is 16 bits per sample at 22050 Hz.

SDL_CDClose — Closes a SDL_CD handle
SDL_CD — CDROM Drive Information
SDL_CDtrack — CD Track Information Structure

SDL supports audio control of up to 32 local CD-ROM drives at once.

You use this API to perform all the basic functions of a CD player, +including listing the tracks, playing, stopping, and ejecting the CD-ROM. +(Currently, multi-changer CD drives are not supported.)

Before you call any of the SDL CD-ROM functions, you must first call +"SDL_Init(SDL_INIT_CDROM)", which scans the system for +CD-ROM drives, and sets the program up for audio control. Check the +return code, which should be 0, to see if there +were any errors in starting up.

After you have initialized the library, you can find out how many drives +are available using the SDL_CDNumDrives() function. +The first drive listed is the system default CD-ROM drive. After you have +chosen a drive, and have opened it with SDL_CDOpen(), +you can check the status and start playing if there's a CD in the drive.

A CD-ROM is organized into one or more tracks, each consisting of a certain +number of "frames". Each frame is ~2K in size, and at normal playing speed, +a CD plays 75 frames per second. SDL works with the number of frames on a +CD, but this can easily be converted to the more familiar minutes/seconds +format by using the FRAMES_TO_MSF() macro.

Chapter 8. Events

Introduction

Event handling allows your application to receive input from the user. Event handling is initalised (along with video) with a call to: +

SDL_Init(SDL_INIT_VIDEO);
+Interally, SDL stores all the events waiting to be handled in an event queue. Using functions like SDL_PollEvent and SDL_PeepEvents you can observe and handle waiting input events.

The key to event handling in SDL is the SDL_Event union. The event queue itself is composed of a series of SDL_Event unions, one for each waiting event. SDL_Event unions are read from the queue with the SDL_PollEvent function and it is then up to the application to process the information stored with them.

Before SDL can be used in a program it must be initialized with SDL_Init. SDL_Init initializes all the subsystems that the user requests (video, audio, joystick, timers and/or cdrom). Once SDL is initialized with SDL_Init subsystems can be shut down and initialized as needed using SDL_InitSubSystem and SDL_QuitSubSystem.

SDL must also be shut down before the program exits to make sure it cleans up correctly. Calling SDL_Quit shuts down all subsystems and frees any resources allocated to SDL.

Initializing SDL

SDL is composed of eight subsystems - Audio, CDROM, Event Handling, File I/O, Joystick Handling, Threading, Timers and Video. Before you can use any of these subsystems they must be initialized by calling SDL_Init (or SDL_InitSubSystem. SDL_Init must be called before any other SDL function. It automatically initializes the Event Handling, File I/O and Threading subsystems and it takes a parameter specifying which other subsystems to initialize. So, to initialize the default subsystems and the Video subsystems you would call: +

    SDL_Init ( SDL_INIT_VIDEO );
+To initialize the default subsystems, the Video subsystem and the Timers subsystem you would call: +
    SDL_Init ( SDL_INIT_VIDEO | SDL_INIT_TIMER );

SDL_Init is complemented by SDL_Quit (and SDL_QuitSubSystem). SDL_Quit shuts down all subsystems, including the default ones. It should always be called before a SDL application exits.

With SDL_Init and SDL_Quit firmly embedded in your programmers toolkit you can write your first and most basic SDL application. However, we must be prepare to handle errors. Many SDL functions return a value and indicates whether the function has succeeded or failed, SDL_Init, for instance, returns -1 if it could not initialize a subsystem. SDL provides a useful facility that allows you to determine exactly what the problem was, every time an error occurs within SDL an error message is stored which can be retrieved using SDL_GetError. Use this often, you can never know too much about an error.

Example 1-1. Initializing SDL

#include "SDL.h"   /* All SDL App's need this */
+#include <stdio.h>
+
+int main() {
+

Chapter 3. Input handling

Handling Joysticks

Initialization

The first step in using a joystick in a SDL program is to initialize the Joystick subsystems of SDL. This done by passing the SDL_INIT_JOYSTICK flag to SDL_Init. The joystick flag will usually be used in conjunction with other flags (like the video flag) because the joystick is usually used to control something.

Example 3-1. Initializing SDL with Joystick Support

    if (SDL_Init( SDL_INIT_VIDEO | SDL_INIT_JOYSTICK ) < 0)
+    {
+        fprintf(stderr, "Couldn't initialize SDL: %s\n", SDL_GetError());
+        exit(1);
+    }

This will attempt to start SDL with both the video and the joystick subsystems activated.

Querying

If we have reached this point then we can safely assume that the SDL library has been initialized and that the Joystick subsystem is active. We can now call some video and/or sound functions to get things going before we need the joystick. Eventually we have to make sure that there is actually a joystick to work with. It's wise to always check even if you know a joystick will be present on the system because it can also help detect when the joystick is unplugged. The function used to check for joysticks is SDL_NumJoysticks.

This function simply returns the number of joysticks available on the system. If it is at least one then we are in good shape. The next step is to determine which joystick the user wants to use. If the number of joysticks available is only one then it is safe to assume that one joystick is the one the user wants to use. SDL has a function to get the name of the joysticks as assigned by the operations system and that function is SDL_JoystickName. The joystick is specified by an index where 0 is the first joystick and the last joystick is the number returned by SDL_NumJoysticks - 1. In the demonstration a list of all available joysticks is printed to stdout.

Example 3-2. Querying the Number of Available Joysticks

    printf("%i joysticks were found.\n\n", SDL_NumJoysticks() );
+    printf("The names of the joysticks are:\n");
+		
+    for( i=0; i < SDL_NumJoysticks(); i++ ) 
+    {
+        printf("    %s\n", SDL_JoystickName(i));
+    }

Opening a Joystick and Receiving Joystick Events

SDL's event driven architecture makes working with joysticks a snap. Joysticks can trigger 4 different types of events: +

SDL_JoyAxisEventOccurs when an axis changes
SDL_JoyBallEventOccurs when a joystick trackball's position changes
SDL_JoyHatEventOccurs when a hat's position changes
SDL_JoyButtonEventOccurs when a button is pressed or released

Events are received from all joysticks opened. The first thing that needs to be done in order to receive joystick events is to call SDL_JoystickEventState with the SDL_ENABLE flag. Next you must open the joysticks that you want to receive envents from. This is done with the SDL_JoystickOpen function. For the example we are only interested in events from the first joystick on the system, regardless of what it may be. To receive events from it we would do this:

Example 3-3. Opening a Joystick

    SDL_Joystick *joystick;
+
+    SDL_JoystickEventState(SDL_ENABLE);
+    joystick = SDL_JoystickOpen(0);

If we wanted to receive events for other joysticks we would open them with calls to SDL_JoystickOpen just like we opened joystick 0, except we would store the SDL_Joystick structure they return in a different pointer. We only need the joystick pointer when we are querying the joysticks or when we are closing the joystick.

Up to this point all the code we have is used just to initialize the joysticks in order to read values at run time. All we need now is an event loop, which is something that all SDL programs should have anyway to receive the systems quit events. We must now add code to check the event loop for at least some of the above mentioned events. Let's assume our event loop looks like this: +

    SDL_Event event;
+    /* Other initializtion code goes here */   
+
+    /* Start main game loop here */
+
+    while(SDL_PollEvent(&event))
+    {  
+        switch(event.type)
+        {  
+            case SDL_KEYDOWN:
+            /* handle keyboard stuff here */				
+            break;
+
+            case SDL_QUIT:
+            /* Set whatever flags are necessary to */
+            /* end the main game loop here */
+            break;
+        }
+    }
+
+    /* End loop here */
+To handle Joystick events we merely add cases for them, first we'll add axis handling code. Axis checks can get kinda of tricky because alot of the joystick events received are junk. Joystick axis have a tendency to vary just a little between polling due to the way they are designed. To compensate for this you have to set a threshold for changes and ignore the events that have'nt exceeded the threshold. 10% is usually a good threshold value. This sounds a lot more complicated than it is. Here is the Axis event handler:

Example 3-4. Joystick Axis Events

    case SDL_JOYAXISMOTION:  /* Handle Joystick Motion */
+    if ( ( event.jaxis.value < -3200 ) || (event.jaxis.value > 3200 ) ) 
+    {
+      /* code goes here */
+    }
+    break;

Another trick with axis events is that up-down and left-right movement are two different sets of axes. The most important axis is axis 0 (left-right) and axis 1 (up-down). To handle them seperatly in the code we do the following:

Example 3-5. More Joystick Axis Events

    case SDL_JOYAXISMOTION:  /* Handle Joystick Motion */
+    if ( ( event.jaxis.value < -3200 ) || (event.jaxis.value > 3200 ) ) 
+    {
+        if( event.jaxis.axis == 0) 
+        {
+            /* Left-right movement code goes here */
+        }
+
+        if( event.jaxis.axis == 1) 
+        {
+            /* Up-Down movement code goes here */
+        }
+    }
+    break;

Ideally the code here should use event.jaxis.value to scale something. For example lets assume you are using the joystick to control the movement of a spaceship. If the user is using an analog joystick and they push the stick a little bit they expect to move less than if they pushed it a lot. Designing your code for this situation is preferred because it makes the experience for users of analog controls better and remains the same for users of digital controls.

If your joystick has any additional axis then they may be used for other sticks or throttle controls and those axis return values too just with different event.jaxis.axis values.

Button handling is simple compared to the axis checking.

Example 3-6. Joystick Button Events

    case SDL_JOYBUTTONDOWN:  /* Handle Joystick Button Presses */
+    if ( event.jbutton.button == 0 ) 
+    {
+        /* code goes here */
+    }
+    break;

Button checks are simpler than axis checks because a button can only be pressed or not pressed. The SDL_JOYBUTTONDOWN event is triggered when a button is pressed and the SDL_JOYBUTTONUP event is fired when a button is released. We do have to know what button was pressed though, that is done by reading the event.jbutton.button field.

Lastly when we are through using our joysticks we should close them with a call to SDL_JoystickClose. To close our opened joystick 0 we would do this at the end of our program: +

    SDL_JoystickClose(joystick);

Advanced Joystick Functions

That takes care of the controls that you can count on being on every joystick under the sun, but there are a few extra things that SDL can support. Joyballs are next on our list, they are alot like axis we a few minor differences. Joyballs store relative changes unlike the the absolute postion stored in a axis event. Also one trackball event contains both the change in x and they change in y. Our case for it is as follows:

Example 3-7. Joystick Ball Events

    case SDL_JOYBALLMOTION:  /* Handle Joyball Motion */
+    if( event.jball.ball == 0 )
+    {
+      /* ball handling */
+    }
+    break;

The above checks the first joyball on the joystick. The change in position will be stored in event.jball.xrel and event.jball.yrel.

Finally we have the hat event. Hats report only the direction they are pushed in. We check hat's position with the bitmasks: + +

SDL_HAT_CENTERED
SDL_HAT_UP
SDL_HAT_RIGHT
SDL_HAT_DOWN
SDL_HAT_LEFT

+ +Also there are some predefined combinations of the above: +

SDL_HAT_RIGHTUP
SDL_HAT_RIGHTDOWN
SDL_HAT_LEFTUP
SDL_HAT_LEFTDOWN

+ +Our case for the hat may resemble the following:

Example 3-8. Joystick Hat Events

    case SDL_JOYHATMOTION:  /* Handle Hat Motion */
+    if ( event.jhat.hat | SDL_HAT_UP )
+    {
+        /* Do up stuff here */
+    }
+
+    if ( event.jhat.hat | SDL_HAT_LEFT )
+    {
+        /* Do left stuff here */
+    }
+
+    if ( event.jhat.hat | SDL_HAT_RIGHTDOWN )
+    {
+        /* Do right and down together stuff here */
+    }
+    break;

In addition to the queries for number of joysticks on the system and their names there are additional functions to query the capabilities of attached joysticks: +

SDL_JoystickNumAxesReturns the number of joysitck axes
SDL_JoystickNumButtonsReturns the number of joysitck buttons
SDL_JoystickNumBallsReturns the number of joysitck balls
SDL_JoystickNumHatsReturns the number of joysitck hats

+ +To use these functions we just have to pass in the joystick structure we got when we opened the joystick. For Example:

Example 3-9. Querying Joystick Characteristics

    int number_of_buttons;
+    SDL_Joystick *joystick;
+
+    joystick = SDL_JoystickOpen(0);
+    number_of_buttons = SDL_JoystickNumButtons(joystick);

This block of code would get the number of buttons on the first joystick in the system.

Handling the Keyboard

Keyboard Related Structures

It should make it a lot easier to understand this tutorial is you are familiar with the data types involved in keyboard access, so I'll explain them first.

SDLKey

SDLKey is an enumerated type defined in SDL/include/SDL_keysym.h and detailed here. Each SDLKey symbol represents a key, SDLK_a corresponds to the 'a' key on a keyboard, SDLK_SPACE corresponds to the space bar, and so on.

SDLMod

SDLMod is an enumerated type, similar to SDLKey, however it enumerates keyboard modifiers (Control, Alt, Shift). The full list of modifier symbols is here. SDLMod values can be AND'd together to represent several modifiers.

SDL_keysym

typedef struct{
+  Uint8 scancode;
+  SDLKey sym;
+  SDLMod mod;
+  Uint16 unicode;
+} SDL_keysym;

The SDL_keysym structure describes a key press or a key release. The scancode field is hardware specific and should be ignored unless you know what your doing. The sym field is the SDLKey value of the key being pressed or released. The mod field describes the state of the keyboard modifiers at the time the key press or release occurred. So a value of KMOD_NUM | KMOD_CAPS | KMOD_LSHIFT would mean that Numlock, Capslock and the left shift key were all press (or enabled in the case of the lock keys). Finally, the unicode field stores the 16-bit unicode value of the key.

Note: It should be noted and understood that this field is only valid when the SDL_keysym is describing a key press, not a key release. Unicode values only make sense on a key press because the unicode value describes an international character and only key presses produce characters. More information on Unicode can be found at www.unicode.org

Note: Unicode translation must be enabled using the SDL_EnableUNICODE function.

SDL_KeyboardEvent

typedef struct{
+  Uint8 type;
+  Uint8 state;
+  SDL_keysym keysym;
+} SDL_KeyboardEvent;

The SDL_KeyboardEvent describes a keyboard event (obviously). The key member of the SDL_Event union is a SDL_KeyboardEvent structure. The type field specifies whether the event is a key release (SDL_KEYUP) or a key press (SDL_KEYDOWN) event. The state is largely redundant, it reports the same information as the type field but uses different values (SDL_RELEASED and SDL_PRESSED). The keysym contains information of the key press or release that this event represents (see above).

Reading Keyboard Events

Reading keybaord events from the event queue is quite simple (the event queue and using it is described here). We read events using SDL_PollEvent in a while() loop and check for SDL_KEYUP and SDL_KEYDOWN events using a switch statement, like so:

Example 3-10. Reading Keyboard Events

  SDL_Event event;
+  .
+  .
+  /* Poll for events. SDL_PollEvent() returns 0 when there are no  */
+  /* more events on the event queue, our while loop will exit when */
+  /* that occurs.                                                  */
+  while( SDL_PollEvent( &event ) ){
+    /* We are only worried about SDL_KEYDOWN and SDL_KEYUP events */
+    switch( event.type ){
+      case SDL_KEYDOWN:
+        printf( "Key press detected\n" );
+        break;
+
+      case SDL_KEYUP:
+        printf( "Key release detected\n" );
+        break;
+
+      default:
+        break;
+    }
+  }
+  .
+  .

This is a very basic example. No information about the key press or release is interpreted. We will explore the other extreme out our first full example below - reporting all available information about a keyboard event.

A More Detailed Look

Before we can read events SDL must be initialised with SDL_Init and a video mode must be set using SDL_SetVideoMode. There are, however, two other functions we must use to obtain all the information required. We must enable unicode translation by calling SDL_EnableUNICODE(1) and we must convert SDLKey values into something printable, using SDL_GetKeyName

Note: It is useful to note that unicode values < 0x80 translate directly a characters ASCII value. THis is used in the example below

Example 3-11. Interpreting Key Event Information

+        
+        /* Initialise SDL */

Game-type Input

I have found that people using keyboard events for games and other interactive applications don't always understand one fundemental point.

Keyboard events only take place when a keys state changes from being unpressed to pressed, and vice versa.

Imagine you have an image of an alien that you wish to move around using the cursor keys - when you pressed the left arrow key you want him to slide over to the left, when you press the down key you want him to slide down the screen. Examine the following code, it highlights and error that many people have made. +

    /* Alien screen coordinates */
+    int alien_x=0, alien_y=0;
+    .
+    .
+    /* Initialise SDL and video modes and all that */
+    .
+    /* Main game loop */
+    /* Check for events */
+    while( SDL_PollEvent( &event ) ){
+        switch( event.type ){
+            /* Look for a keypress */
+            case SDL_KEYDOWN:
+                /* Check the SDLKey values and move change the coords */
+                switch( event.key.keysym.sym ){
+                    case SDLK_LEFT:
+                        alien_x -= 1;
+                        break;
+                    case SDLK_RIGHT:
+                        alien_x += 1;
+                        break;
+                    case SDLK_UP:
+                        alien_y -= 1;
+                        break;
+                    case SDLK_DOWN:
+                        alien_y += 1;
+                        break;
+                    default:
+                        break;
+                }
+            }
+        }
+    }
+    .
+    .
+At first glance you may think this is a perfectly reasonable piece of code for the task, but it isn't. Like I said keyboard events only occur when a key changes state, so the user would have to press and release the left cursor key 100 times to move the alien 100 pixels to the left.

To get around this problem we must not use the events to change the position of the alien, we use the events to set flags which are then used in a seperate section of code to move the alien. Something like this:

Example 3-12. Proper Game Movement

    /* Alien screen coordinates */
+    int alien_x=0, alien_y=0;
+    int alien_xvel=0, alien_yvel=0;
+    .
+    .
+    /* Initialise SDL and video modes and all that */
+    .
+    /* Main game loop */
+    /* Check for events */
+    while( SDL_PollEvent( &event ) ){
+        switch( event.type ){
+            /* Look for a keypress */
+            case SDL_KEYDOWN:
+                /* Check the SDLKey values and move change the coords */
+                switch( event.key.keysym.sym ){
+                    case SDLK_LEFT:
+                        alien_xvel = -1;
+                        break;
+                    case SDLK_RIGHT:
+                        alien_xvel =  1;
+                        break;
+                    case SDLK_UP:
+                        alien_yvel = -1;
+                        break;
+                    case SDLK_DOWN:
+                        alien_yvel =  1;
+                        break;
+                    default:
+                        break;
+                }
+                break;
+            /* We must also use the SDL_KEYUP events to zero the x */
+            /* and y velocity variables. But we must also be       */
+            /* careful not to zero the velocities when we shouldn't*/
+            case SDL_KEYUP:
+                switch( event.key.keysym.sym ){
+                    case SDLK_LEFT:
+                        /* We check to make sure the alien is moving */
+                        /* to the left. If it is then we zero the    */
+                        /* velocity. If the alien is moving to the   */
+                        /* right then the right key is still press   */
+                        /* so we don't tocuh the velocity            */
+                        if( alien_xvel < 0 )
+                            alien_xvel = 0;
+                        break;
+                    case SDLK_RIGHT:
+                        if( alien_xvel > 0 )
+                            alien_xvel = 0;
+                        break;
+                    case SDLK_UP:
+                        if( alien_yvel < 0 )
+                            alien_yvel = 0;
+                        break;
+                    case SDLK_DOWN:
+                        if( alien_yvel > 0 )
+                            alien_yvel = 0;
+                        break;
+                    default:
+                        break;
+                }
+                break;
+            
+            default:
+                break;
+        }
+    }
+    .
+    .
+    /* Update the alien position */
+    alien_x += alien_xvel;
+    alien_y += alien_yvel;

As can be seen, we use two extra variables, alien_xvel and alien_yvel, which represent the motion of the ship, it is these variables that we update when we detect keypresses and releases.

Preface

About SDL

The SDL library is designed to make it easy to write games that run on Linux, *BSD, MacOS, Win32 and BeOS using the various native high-performance media interfaces, (for video, audio, etc) and presenting a single source-code level API to your application. SDL is a fairly low level API, but using it, completely portable applications can be written with a great deal of flexibility.

Chapter 2. Graphics and Video

Introduction to SDL Video

Video is probably the most common thing that SDL is used for, and +so it has the most complete subsystem. Here are a few +examples to demonstrate the basics.

Initializing the Video Display

This is what almost all SDL programs have to do in one way or +another.

Example 2-1. Initializing the Video Display

    SDL_Surface *screen;
+
+    /* Initialize the SDL library */
+    if( SDL_Init(SDL_INIT_VIDEO) < 0 ) {
+        fprintf(stderr,
+                "Couldn't initialize SDL: %s\n", SDL_GetError());
+        exit(1);
+    }
+
+    /* Clean up on exit */
+    atexit(SDL_Quit);
+    
+    /*
+     * Initialize the display in a 640x480 8-bit palettized mode,
+     * requesting a software surface
+     */
+    screen = SDL_SetVideoMode(640, 480, 8, SDL_SWSURFACE);
+    if ( screen == NULL ) {
+        fprintf(stderr, "Couldn't set 640x480x8 video mode: %s\n",
+                        SDL_GetError());
+        exit(1);
+    }

Initializing the Best Video Mode

If you have a preference for a certain pixel depth but will accept any +other, use SDL_SetVideoMode with SDL_ANYFORMAT as below. You can also +use SDL_VideoModeOK() to find the native video mode that is closest to +the mode you request.

Example 2-2. Initializing the Best Video Mode

    /* Have a preference for 8-bit, but accept any depth */
+    screen = SDL_SetVideoMode(640, 480, 8, SDL_SWSURFACE|SDL_ANYFORMAT);
+    if ( screen == NULL ) {
+        fprintf(stderr, "Couldn't set 640x480x8 video mode: %s\n",
+                        SDL_GetError());
+        exit(1);
+    }
+    printf("Set 640x480 at %d bits-per-pixel mode\n",
+           screen->format->BitsPerPixel);

Loading and Displaying a BMP File

The following function loads and displays a BMP file given as +argument, once SDL is initialised and a video mode has been set.

Example 2-3. Loading and Displaying a BMP File

void display_bmp(char *file_name)
+{
+    SDL_Surface *image;
+
+    /* Load the BMP file into a surface */
+    image = SDL_LoadBMP(file_name);
+    if (image == NULL) {
+        fprintf(stderr, "Couldn't load %s: %s\n", file_name, SDL_GetError());
+        return;
+    }
+
+    /*
+     * Palettized screen modes will have a default palette (a standard
+     * 8*8*4 colour cube), but if the image is palettized as well we can
+     * use that palette for a nicer colour matching
+     */
+    if (image->format->palette && screen->format->palette) {
+    SDL_SetColors(screen, image->format->palette->colors, 0,
+                  image->format->palette->ncolors);
+    }
+
+    /* Blit onto the screen surface */
+    if(SDL_BlitSurface(image, NULL, screen, NULL) < 0)
+        fprintf(stderr, "BlitSurface error: %s\n", SDL_GetError());
+
+    SDL_UpdateRect(screen, 0, 0, image->w, image->h);
+
+    /* Free the allocated BMP surface */
+    SDL_FreeSurface(image);
+}

Drawing Directly to the Display

The following two functions can be used to get and set single +pixels of a surface. They are carefully written to work with any depth +currently supported by SDL. Remember to lock the surface before +calling them, and to unlock it before calling any other SDL +functions.

To convert between pixel values and their red, green, blue +components, use SDL_GetRGB() and SDL_MapRGB().

Example 2-4. getpixel()

/*
+ * Return the pixel value at (x, y)
+ * NOTE: The surface must be locked before calling this!
+ */
+Uint32 getpixel(SDL_Surface *surface, int x, int y)
+{
+    int bpp = surface->format->BytesPerPixel;
+    /* Here p is the address to the pixel we want to retrieve */
+    Uint8 *p = (Uint8 *)surface->pixels + y * surface->pitch + x * bpp;
+
+    switch(bpp) {
+    case 1:
+        return *p;
+
+    case 2:
+        return *(Uint16 *)p;
+
+    case 3:
+        if(SDL_BYTEORDER == SDL_BIG_ENDIAN)
+            return p[0] << 16 | p[1] << 8 | p[2];
+        else
+            return p[0] | p[1] << 8 | p[2] << 16;
+
+    case 4:
+        return *(Uint32 *)p;
+
+    default:
+        return 0;       /* shouldn't happen, but avoids warnings */
+    }
+}

Example 2-5. putpixel()

/*
+ * Set the pixel at (x, y) to the given value
+ * NOTE: The surface must be locked before calling this!
+ */
+void putpixel(SDL_Surface *surface, int x, int y, Uint32 pixel)
+{
+    int bpp = surface->format->BytesPerPixel;
+    /* Here p is the address to the pixel we want to set */
+    Uint8 *p = (Uint8 *)surface->pixels + y * surface->pitch + x * bpp;
+
+    switch(bpp) {
+    case 1:
+        *p = pixel;
+        break;
+
+    case 2:
+        *(Uint16 *)p = pixel;
+        break;
+

Fastest possible surface blit

There are three different ways you can draw an image to the screen: +

1.Create a surface and use SDL_BlitSurface to blit it to the screen
2.Create the video surface in system memory and call SDL_UpdateRect
3.Create the video surface in video memory and call SDL_LockSurface

+The best way to do this is to combine methods: +
#include <stdio.h>
+#include <stdlib.h>
+#include "SDL.h"
+#include "SDL_timer.h"

Using OpenGL With SDL

SDL has the ability to create and use OpenGL contexts on several platforms(Linux/X11, Win32, BeOS, MacOS Classic/Toolbox, MacOS X, FreeBSD/X11 and Solaris/X11). This allows you to use SDL's audio, event handling, threads and times in your OpenGL applications (a function often performed by GLUT).

Initialisation

Initialising SDL to use OpenGL is not very different to initialising SDL normally. There are three differences; you must pass SDL_OPENGL to SDL_SetVideoMode, you must specify several GL attributes (depth buffer size, framebuffer sizes) using SDL_GL_SetAttribute and finally, if you wish to use double buffering you must specify it as a GL attribute, not by passing the SDL_DOUBLEBUF flag to SDL_SetVideoMode.

Example 2-7. Initializing SDL with OpenGL

    /* Information about the current video settings. */
+    const SDL_VideoInfo* info = NULL;
+    /* Dimensions of our window. */
+    int width = 0;
+    int height = 0;
+    /* Color depth in bits of our window. */
+    int bpp = 0;
+    /* Flags we will pass into SDL_SetVideoMode. */
+    int flags = 0;
+
+    /* First, initialize SDL's video subsystem. */
+    if( SDL_Init( SDL_INIT_VIDEO ) < 0 ) {
+        /* Failed, exit. */
+        fprintf( stderr, "Video initialization failed: %s\n",
+             SDL_GetError( ) );
+        quit_tutorial( 1 );
+    }
+
+    /* Let's get some video information. */
+    info = SDL_GetVideoInfo( );
+
+    if( !info ) {
+        /* This should probably never happen. */
+        fprintf( stderr, "Video query failed: %s\n",
+             SDL_GetError( ) );
+        quit_tutorial( 1 );
+    }
+
+    /*
+     * Set our width/height to 640/480 (you would
+     * of course let the user decide this in a normal
+     * app). We get the bpp we will request from
+     * the display. On X11, VidMode can't change
+     * resolution, so this is probably being overly
+     * safe. Under Win32, ChangeDisplaySettings
+     * can change the bpp.

+    width = 640;
+    height = 480;
+    bpp = info->vfmt->BitsPerPixel;

+    /*

+     * window attributes for our OpenGL window.
+     * We want *at least* 5 bits of red, green

+         * including DISPLAY not being set, the specified
+         * resolution not being available, etc.
+         */
+        fprintf( stderr, "Video mode set failed: %s\n",
+             SDL_GetError( ) );
+        quit_tutorial( 1 );
+    }

Drawing

Apart from initialisation, using OpenGL within SDL is the same as using OpenGL +with any other API, e.g. GLUT. You still use all the same function calls and +data types. However if you are using a double-buffered display, then you must +use +SDL_GL_SwapBuffers() +to swap the buffers and update the display. To request double-buffering +with OpenGL, use +SDL_GL_SetAttribute +with SDL_GL_DOUBLEBUFFER, and use +SDL_GL_GetAttribute +to see if you actually got it.

A full example code listing is now presented below.

SDL_NumJoysticks — Count available joysticks.

SDL_JoystickOpen — Opens a joystick for use.

Joysticks, and other similar input devices, have a very strong role in game playing and SDL provides comprehensive support for them. Axes, Buttons, POV Hats and trackballs are all supported.

Joystick support is initialized by passed the SDL_INIT_JOYSTICK flag to SDL_Init. Once initilized joysticks must be opened using SDL_JoystickOpen.

While using the functions describe in this secton may seem like the best way to access and read from joysticks, in most cases they aren't. Ideally joysticks should be read using the event system. To enable this, you must set the joystick event processing state with SDL_JoystickEventState. Joysticks must be opened before they can be used of course.

Note: If you are not handling the joystick via the event queue then you must explicitly request a joystick update by calling SDL_JoystickUpdate.

Note: Force Feedback is not yet support. Sam (slouken@libsdl.org) is soliciting suggestions from people with force-feedback experience on the best wat to desgin the API.

SDL_ActiveEvent

Name

SDL_ActiveEvent -- Application visibility event structure

Structure Definition

typedef struct{
+  Uint8 type;
+  Uint8 gain;
+  Uint8 state;
+} SDL_ActiveEvent;

Structure Data

typeSDL_ACTIVEEVENT.
gain0 if the event is a loss or 1 if it is a gain.
stateSDL_APPMOUSEFOCUS if mouse focus was gained or lost, SDL_APPINPUTFOCUS if input focus was gained or lost, or SDL_APPACTIVE if the application was iconified (gain=0) or restored(gain=1).

Description

SDL_ActiveEvent is a member of the SDL_Event union and is used when an event of type SDL_ACTIVEEVENT is reported.

When the mouse leaves or enters the window area a SDL_APPMOUSEFOCUS type activation event occurs, if the mouse entered the window then gain will be 1, otherwise gain will be 0. A SDL_APPINPUTFOCUS type activation event occurs when the application loses or gains keyboard focus. This usually occurs when another application is made active. Finally, a SDL_APPACTIVE type event occurs when the application is either minimised/iconified (gain=0) or restored.

Note: This event does not occur when an application window is first created.

SDL_AddTimer

Name

SDL_AddTimer -- Add a timer which will call a callback after the specified number of milliseconds has +elapsed.

Synopsis

#include "SDL.h"

SDL_TimerID SDL_AddTimer(Uint32 interval, SDL_NewTimerCallback callback, void *param);

Callback

/* type definition for the "new" timer callback function */
+typedef Uint32 (*SDL_NewTimerCallback)(Uint32 interval, void *param);

Description

Adds a callback function to be run after the specified number of +milliseconds has elapsed. The callback function is passed the current +timer interval and the user supplied parameter from the +SDL_AddTimer call and returns the next timer +interval. If the returned value from the callback is the same as the one +passed in, the periodic alarm continues, otherwise a new alarm is +scheduled.

To cancel a currently running timer call +SDL_RemoveTimer with the +timer ID returned from +SDL_AddTimer.

The timer callback function may run in a different thread than your +main program, and so shouldn't call any functions from within itself. +You may always call SDL_PushEvent, however.

The granularity of the timer is platform-dependent, but you should count +on it being at least 10 ms as this is the most common number. +This means that if +you request a 16 ms timer, your callback will run approximately 20 ms +later on an unloaded system. If you wanted to set a flag signaling +a frame update at 30 frames per second (every 33 ms), you might set a +timer for 30 ms (see example below). + +If you use this function, you need to pass SDL_INIT_TIMER +to SDL_Init.

Return Value

Returns an ID value for the added timer or +NULL if there was an error.

Examples

my_timer_id = SDL_AddTimer((33/10)*10, my_callbackfunc, my_callback_param);

The SDL_AudioCVT is used to convert audio data between different formats. A SDL_AudioCVT structure is created with the SDL_BuildAudioCVT function, while the actual conversion is done by the SDL_ConvertAudio function.

Many of the fields in the SDL_AudioCVT structure should be considered private and their function will not be discussed here.

Uint8 *buf

This points to the audio data that will be used in the conversion. It is both the source and the destination, which means the converted audio data overwrites the original data. It also means that the converted data may be larger than the original data (if you were converting from 8-bit to 16-bit, for instance), so you must ensure buf is large enough. See below.

int len

This is the length of the original audio data in bytes.

int len_mult

As explained above, the audio buffer needs to be big enough to store the converted data, which may be bigger than the original audio data. The length of buf should be len*len_mult.

double len_ratio

When you have finished converting your audio data, you need to know how much of your audio buffer is valid. len*len_ratio is the size of the converted audio data in bytes. This is very similar to len_mult, however when the convert audio data is shorter than the original len_mult would be 1. len_ratio, on the other hand, would be a fractional number between 0 and 1.

SDL_AudioSpec

Name

SDL_AudioSpec -- Audio Specification Structure

Structure Definition

typedef struct{
+  int freq;
+  Uint16 format;
+  Uint8 channels;
+  Uint8 silence;
+  Uint16 samples;
+  Uint32 size;
+  void (*callback)(void *userdata, Uint8 *stream, int len);
+  void *userdata;
+} SDL_AudioSpec;

Structure Data

freqAudio frequency in samples per second
formatAudio data format
channelsNumber of channels: 1 mono, 2 stereo
silenceAudio buffer silence value (calculated)
samplesAudio buffer size in samples
sizeAudio buffer size in bytes (calculated)
callback(..)Callback function for filling the audio buffer
userdataPointer the user data which is passed to the callback function

Description

The SDL_AudioSpec structure is used to describe the format of some audio data. This structure is used by SDL_OpenAudio and SDL_LoadWAV. While all fields are used by SDL_OpenAudio only freq, format, samples and channels are used by SDL_LoadWAV. We will detail these common members here.

freq

The number of samples sent to the sound device every second. Common values are 11025, 22050 and 44100. The higher the better.

format

Specifies the size and type of each sample element +

AUDIO_U8

Unsigned 8-bit samples

AUDIO_S8

Signed 8-bit samples

AUDIO_U16 or AUDIO_U16LSB

Unsigned 16-bit little-endian samples

AUDIO_S16 or AUDIO_S16LSB

Signed 16-bit little-endian samples

AUDIO_U16MSB

Unsigned 16-bit big-endian samples

AUDIO_S16MSB

Signed 16-bit big-endian samples

AUDIO_U16SYS

Either AUDIO_U16LSB or AUDIO_U16MSB depending on you systems endianness

AUDIO_S16SYS

Either AUDIO_S16LSB or AUDIO_S16MSB depending on you systems endianness

channelsThe number of seperate sound channels. 1 is mono (single channel), 2 is stereo (dual channel).
samplesWhen used with SDL_OpenAudio this refers to the size of the audio buffer in samples. A sample a chunk of audio data of the size specified in format mulitplied by the number of channels. When the SDL_AudioSpec is used with SDL_LoadWAV samples is set to 4096.

SDL_BlitSurface

Name

SDL_BlitSurface -- This performs a fast blit from the source surface to the destination surface.

Synopsis

#include "SDL.h"

int SDL_BlitSurface(SDL_Surface *src, SDL_Rect *srcrect, SDL_Surface *dst, SDL_Rect *dstrect);

Description

This performs a fast blit from the source surface to the destination surface.

Only the position is used in the dstrect (the +width and height are ignored).

If either srcrect or +dstrect are NULL, the entire +surface (src or dst) is +copied.

The final blit rectangle is saved in +dstrect after all clipping is performed +(srcrect is not modified).

The blit function should not be called on a locked surface.

The results of blitting operations vary greatly depending on whether SDL_SRCAPLHA is set or not. See SDL_SetAlpha for an explaination of how this affects your results. Colorkeying and alpha attributes also interact with surface blitting, as the following pseudo-code should hopefully explain. +

if (source surface has SDL_SRCALPHA set) {
+    if (source surface has alpha channel (that is, format->Amask != 0))
+        blit using per-pixel alpha, ignoring any colour key
+    else {
+        if (source surface has SDL_SRCCOLORKEY set)
+            blit using the colour key AND the per-surface alpha value
+        else
+            blit using the per-surface alpha value
+    }
+} else {
+    if (source surface has SDL_SRCCOLORKEY set)
+        blit using the colour key
+    else
+        ordinary opaque rectangular blit
+}

Return Value

If the blit is successful, it returns 0, +otherwise it returns -1.

If either of the surfaces were in video memory, and the blit returns +-2, the video memory was lost, so it should be +reloaded with artwork and re-blitted: +

        while ( SDL_BlitSurface(image, imgrect, screen, dstrect) == -2 ) {
+                while ( SDL_LockSurface(image)) < 0 )
+                        Sleep(10);
+                -- Write image pixels to image->pixels --
+                SDL_UnlockSurface(image);
+        }
+This happens under DirectX 5.0 when the system switches away from your +fullscreen application. Locking the surface will also fail until you +have access to the video memory again.

SDL_BuildAudioCVT

Name

SDL_BuildAudioCVT -- Initializes a SDL_AudioCVT structure for conversion

Synopsis

#include "SDL.h"

int SDL_BuildAudioCVT(SDL_AudioCVT *cvt, Uint16 src_format, Uint8 src_channels, int src_rate, Uint16 dst_format, Uint8 dst_channels, int dst_rate);

Description

Before an SDL_AudioCVT structure can be used to convert audio data it must be initialized with source and destination information.

src_format and dst_format are the source and destination format of the conversion. (For information on audio formats see SDL_AudioSpec). src_channels and dst_channels are the number of channels in the source and destination formats. Finally, src_rate and dst_rate are the frequency or samples-per-second of the source and destination formats. Once again, see SDL_AudioSpec.

Return Values

Returns -1 if the filter could not be built or 1 if it could.

Examples

See SDL_ConvertAudio.

+  CDstatus status;
+  int numtracks;
+  int cur_track;
+  int cur_frame;
+  SDL_CDtrack track[SDL_MAX_TRACKS+1];

Description

An SDL_CD structure is returned by SDL_CDOpen. It represents an opened CDROM device and stores information on the layout of the tracks on the disc.

A frame is the base data unit of a CD. CD_FPS frames is equal to 1 second of music. SDL provides two macros for converting between time and frames: FRAMES_TO_MSF(f, M,S,F) and MSF_TO_FRAMES.

Examples

int min, sec, frame;
+int frame_offset;
+
+FRAMES_TO_MSF(cdrom->cur_frame, &min, &sec, &frame);
+printf("Current Position: %d minutes, %d seconds, %d frames\n", min, sec, frame);

/* Given a status, returns true if there's a disk in the drive */
+#define CD_INDRIVE(status)      ((int)status > 0)

Description

This function returns the current status of the given drive. Status is described like so: +

typedef enum {
+  CD_TRAYEMPTY,
+  CD_STOPPED,
+  CD_PLAYING,
+  CD_PAUSED,
+  CD_ERROR = -1
+} CDstatus;

If the drive has a CD in it, the table of contents of the CD and current +play position of the CD will be stored in the SDL_CD structure.

The macro CD_INDRIVE is provided for convenience, +and given a status returns true if there's a disk in the drive.

Note: SDL_CDStatus also updates the SDL_CD structure passed to it.

Example

int playTrack(int track)
+{
+  int playing = 0;
+
+  if ( CD_INDRIVE(SDL_CDStatus(cdrom)) ) {
+  /* clamp to the actual number of tracks on the CD */
+    if (track >= cdrom->numtracks) {
+      track = cdrom->numtracks-1;
+    }
+
+    if ( SDL_CDPlayTracks(cdrom, track, 0, 1, 0) == 0 ) {

SDL_ConvertAudio

Name

SDL_ConvertAudio -- Convert audio data to a desired audio format.

Synopsis

#include "SDL.h"

int SDL_ConvertAudio(SDL_AudioCVT *cvt);

Description

SDL_ConvertAudio takes one parameter, cvt, which was previously initilized. Initilizing a SDL_AudioCVT is a two step process. First of all, the structure must be passed to SDL_BuildAudioCVT along with source and destination format parameters. Secondly, the cvt->buf and cvt->len fields must be setup. cvt->buf should point to the audio data and cvt->len should be set to the length of the audio data in bytes. Remember, the length of the buffer pointed to by buf show be len*len_mult bytes in length.

Once the SDL_AudioCVTstructure is initilized then we can pass it to SDL_ConvertAudio, which will convert the audio data pointer to by cvt->buf. If SDL_ConvertAudio returned 0 then the conversion was completed successfully, otherwise -1 is returned.

If the conversion completed successfully then the converted audio data can be read from cvt->buf. The amount of valid, converted, audio data in the buffer is equal to cvt->len*cvt->len_ratio.

Examples

/* Converting some WAV data to hardware format */
+void my_audio_callback(void *userdata, Uint8 *stream, int len);

Name

Synopsis

#include "SDL.h"

SDL_Surface *SDL_CreateRGBSurface(Uint32 flags, int width, int height, int depth, Uint32 Rmask, Uint32 Gmask, Uint32 Bmask, Uint32 Amask);

Description

Allocate an empty surface (must be called after SDL_SetVideoMode)

If depth is 8 bits an empty palette is allocated for the surface, otherwise a 'packed-pixel' SDL_PixelFormat is created using the [RGBA]mask's provided (see SDL_PixelFormat). The flags specifies the type of surface that should be created, it is an OR'd combination of the following possible values.

SDL_SWSURFACESDL will create the surface in system memory. This improves the performance of pixel level access, however you may not be able to take advantage of some types of hardware blitting.
SDL_HWSURFACESDL will attempt to create the surface in video memory. This will allow SDL to take advantage of Video->Video blits (which are often accelerated).
SDL_SRCCOLORKEYThis flag turns on colourkeying for blits from this surface. If +SDL_HWSURFACE is also specified and colourkeyed blits +are hardware-accelerated, then SDL will attempt to place the surface in +video memory. +Use SDL_SetColorKey +to set or clear this flag after surface creation.
SDL_SRCALPHAThis flag turns on alpha-blending for blits from this surface. If +SDL_HWSURFACE is also specified and alpha-blending blits +are hardware-accelerated, then the surface will be placed in video memory if +possible. +Use SDL_SetAlpha to +set or clear this flag after surface creation.

Note: If an alpha-channel is specified (that is, if Amask is +nonzero), then the SDL_SRCALPHA flag is automatically +set. You may remove this flag by calling +SDL_SetAlpha +after surface creation.

Return Value

Returns the created surface, or NULL upon error.

Example

    /* Create a 32-bit surface with the bytes of each pixel in R,G,B,A order,
+       as expected by OpenGL for textures */
+    SDL_Surface *surface;
+    Uint32 rmask, gmask, bmask, amask;

Description

Creates an SDL_Surface from the provided pixel data.

The data stored in pixels is assumed to be of the depth specified in the parameter list. The pixel data is not copied into the SDL_Surface structure so it should not be freed until the surface has been freed with a called to SDL_FreeSurface. pitch is the length of each scanline in bytes.

See SDL_CreateRGBSurface for a more detailed description of the other parameters.

Return Value

Returns the created surface, or NULL upon error.

Description

This function takes a surface and copies it to a new surface of the +pixel format and colors of the video framebuffer plus an alpha channel, +suitable for fast blitting onto the display surface. It calls +SDL_ConvertSurface

If you want to take advantage of hardware colorkey or alpha blit +acceleration, you should set the colorkey and alpha value before +calling this function.

This function can be used to convert a colourkey to an alpha channel, +if the SDL_SRCCOLORKEY flag is set on the surface. +The generated surface will then be transparent (alpha=0) where the +pixels match the colourkey, and opaque (alpha=255) elsewhere.

Return Value

+} SDL_Event;

Description

The SDL_Event union is the core to all event handling is SDL, its probably the most important structure after SDL_Surface. SDL_Event is a union of all event structures used in SDL, using it is a simple matter of knowing which union member relates to which event type.

SDL_SYSWMEVENTSDL_SysWMEvent
SDL_VIDEORESIZESDL_ResizeEvent
SDL_USEREVENTSDL_UserEvent

Use

The SDL_Event structure has two uses

  • Reading events on the event queue

  • Placing events on the event queue

Reading events from the event queue is done with either SDL_PollEvent or SDL_PeepEvents. We'll use SDL_PollEvent and step through an example.

First off, we create an empty SDL_Event structure. +

SDL_Event test_event;
+SDL_PollEvent removes the next event from the event queue, if there are no events on the queue it returns 0 otherwise it returns 1. We use a while loop to process each event in turn. +
while(SDL_PollEvent(&test_event)) {
+The SDL_PollEvent function take a pointer to an SDL_Event structure that is to be filled with event information. We know that if SDL_PollEvent removes an event from the queue then the event information will be placed in our test_event structure, but we also know that the type of event will be placed in the type member of test_event. So to handle each event type seperately we use a switch statement. +
  switch(test_event.type) {
+We need to know what kind of events we're looking for and the event type's of those events. So lets assume we want to detect where the user is moving the mouse pointer within our application. We look through our event types and notice that SDL_MOUSEMOTION is, more than likely, the event we're looking for. A little more research tells use that SDL_MOUSEMOTION events are handled within the SDL_MouseMotionEvent structure which is the motion member of SDL_Event. We can check for the SDL_MOUSEMOTION event type within our switch statement like so: +
    case SDL_MOUSEMOTION:
+All we need do now is read the information out of the motion member of test_event. +
      printf("We got a motion event.\n");
+      printf("Current mouse position is: (%d, %d)\n", test_event.motion.x, test_event.motion.y);
+      break;
+    default:
+      printf("Unhandled Event!\n");
+      break;
+  }
+}
+printf("Event queue empty.\n");

It is also possible to push events onto the event queue and so use it as a two-way communication path. Both SDL_PushEvent and SDL_PeepEvents allow you to place events onto the event queue. This is usually used to place a SDL_USEREVENT on the event queue, however you could use it to post fake input events if you wished. Creating your own events is a simple matter of choosing the event type you want, setting the type member and filling the appropriate member structure with information. +

SDL_Event user_event;
+
+user_event.type=SDL_USEREVENT;
+user_event.user.code=2;
+user_event.user.data1=NULL;
+user_event.user.data2=NULL;
+SDL_PushEvent(&user_event);

Description

This function allows you to set the state of processing certain event type's.

If state is set to SDL_IGNORE, +that event type will be automatically dropped from the event queue and will +not be filtered.

If state is set to SDL_ENABLE, +that event type will be processed normally.

If state is set to SDL_QUERY, +SDL_EventState will return the current processing +state of the specified event type.

A list of event type's can be found in the SDL_Event section.

int SDL_Flip(SDL_Surface *screen);

Description

On hardware that supports double-buffering, this function sets up a flip +and returns. The hardware will wait for vertical retrace, and then swap +video buffers before the next video surface blit or lock will return. +On hardware that doesn't support double-buffering, this is equivalent +to calling SDL_UpdateRect(screen, 0, 0, 0, 0)

The SDL_DOUBLEBUF flag must have been passed to +SDL_SetVideoMode, + when +setting the video mode for this function to perform hardware flipping.

Return Value

This function returns 0 if successful, or +-1 if there was an error.

SDL_JoystickEventState

Name

SDL_JoystickEventState -- Enable/disable joystick event polling

Synopsis

#include "SDL.h"

int SDL_JoystickEventState(int state);

Description

This function is used to enable or disable joystick event processing. With joystick event processing disabled you will have to update joystick states with SDL_JoystickUpdate and read the joystick information manually. state is either SDL_QUERY, SDL_ENABLE or SDL_IGNORE.

Note: Joystick event handling is prefered

Return Value

If state is SDL_QUERY then the current state is returned, otherwise the new processing state is returned.

SDL_JoystickGetAxis

Name

SDL_JoystickGetAxis -- Get the current state of an axis

Synopsis

#include "SDL.h"

Sint16 SDL_JoystickGetAxis(SDL_Joystick *joystick, int axis);

Description

SDL_JoystickGetAxis returns the current state of the given axis on the given joystick.

On most modern joysticks the X axis is usually represented by axis 0 and the Y axis by axis 1. The value returned by SDL_JoystickGetAxis is a signed integer (-32768 to 32768) representing the current position of the axis, it maybe necessary to impose certain tolerances on these values to account for jitter. It is worth noting that some joysticks use axes 2 and 3 for extra buttons.

Return Value

Returns a 16-bit signed integer representing the current position of the axis.

Examples

Sint16 x_move, y_move;
+SDL_Joystick *joy1;
+.
+.
+x_move=SDL_JoystickGetAxis(joy1, 0);
+y_move=SDL_JoystickGetAxis(joy1, 1);

Name

SDL_KeyboardEvent -- Keyboard event structure

Structure Definition

typedef struct{
+  Uint8 type;
+  Uint8 state;
+  SDL_keysym keysym;
+} SDL_KeyboardEvent;

Structure Data

typeSDL_KEYDOWN or SDL_KEYUP
stateSDL_PRESSED or SDL_RELEASED
keysymContains key press information

Description

SDL_KeyboardEvent is a member of the SDL_Event union and is used when an event of type SDL_KEYDOWN or SDL_KEYUP is reported.

The type and state actually report the same information, they just use different values to do it! A keyboard event occurs when a key is released (type=SDK_KEYUP or state=SDL_RELEASED) and when a key is pressed (type=SDL_KEYDOWN or state=SDL_PRESSED). The information on what key was pressed or released is in the keysym structure.

Note: Repeating SDL_KEYDOWN events will occur if key repeat is enabled (see SDL_EnableKeyRepeat).

SDL_keysym -- Keysym structure

Structure Definition

typedef struct{
+  Uint8 scancode;
+  SDLKey sym;
+  SDLMod mod;
+  Uint16 unicode;
+} SDL_keysym;

Structure Data

scancodeHardware specific scancode
symSDL virtual keysym
modCurrent key modifiers
unicodeTranslated character

Description

The SDL_keysym structure is used by reporting key presses and releases since it is a part of the SDL_KeyboardEvent.

The scancode field should generally be left alone, it is the hardware dependent scancode returned by the keyboard. The sym field is extremely useful. It is the SDL-defined value of the key (see SDL Key Syms. This field is very useful when you are checking for certain key presses, like so: +

.
+.
+while(SDL_PollEvent(&event)){
+  switch(event.type){
+    case SDL_KEYDOWN:
+      if(event.key.keysym.sym==SDLK_LEFT)
+        move_left();
+      break;
+    .
+    .
+    .
+  }
+}
+.
+.
+mod stores the current state of the keyboard modifiers as explained in SDL_GetModState. The unicode is only used when UNICODE translation is enabled with SDL_EnableUNICODE. If unicode is non-zero then this a the UNICODE character corresponding to the keypress. If the high 9 bits of the character are 0, then this maps to the equivalent ASCII character: +
char ch;
+if ( (keysym.unicode & 0xFF80) == 0 ) {
+  ch = keysym.unicode & 0x7F;
+}
+else {
+  printf("An International Character.\n");
+}
+UNICODE translation does have a slight overhead so don't enable it unless its needed.

SDL_ListModes

Name

SDL_ListModes -- Returns a pointer to an array of available screen dimensions for +the given format and video flags

Synopsis

#include "SDL.h"

SDL_Rect **SDL_ListModes(SDL_PixelFormat *format, Uint32 flags);

Description

Return a pointer to an array of available screen dimensions for the given +format and video flags, sorted largest to smallest. Returns +NULL if there are no dimensions available for a particular +format, or -1 if any dimension is okay for +the given format.

If format is NULL, the mode list +will be for the format returned by SDL_GetVideoInfo()->vfmt. The flag parameter is an OR'd combination of surface flags. The flags are the same as those used SDL_SetVideoMode and they play a strong role in deciding what modes are valid. For instance, if you pass SDL_HWSURFACE as a flag only modes that support hardware video surfaces will be returned.

Example

SDL_Rect **modes;
+int i;
+.
+.
+.
+
+/* Get available fullscreen/hardware modes */
+modes=SDL_ListModes(NULL, SDL_FULLSCREEN|SDL_HWSURFACE);
+
+/* Check is there are any modes available */
+if(modes == (SDL_Rect **)0){
+  printf("No modes available!\n");
+  exit(-1);
+}
+
+/* Check if or resolution is restricted */
+if(modes == (SDL_Rect **)-1){
+  printf("All resolutions available.\n");
+}
+else{
+  /* Print valid modes */
+  printf("Available Modes\n");
+  for(i=0;modes[i];++i)
+    printf("  %d x %d\n", modes[i]->w, modes[i]->h);
+}

SDL_LoadWAV

Name

SDL_LoadWAV -- Load a WAVE file

Synopsis

#include "SDL.h"

SDL_AudioSpec *SDL_LoadWAV(const char *file, SDL_AudioSpec *spec, Uint8 **audio_buf, Uint32 *audio_len);

Description

SDL_LoadWAV +This function loads a WAVE file into memory.

If this function succeeds, it returns the given +SDL_AudioSpec, +filled with the audio data format of the wave data, and sets +audio_buf to a malloc'd +buffer containing the audio data, and sets audio_len +to the length of that audio buffer, in bytes. You need to free the audio +buffer with SDL_FreeWAV when you are +done with it.

This function returns NULL and sets the SDL +error message if the wave file cannot be opened, uses an unknown data format, +or is corrupt. Currently raw, MS-ADPCM and IMA-ADPCM WAVE files are supported.

Example

SDL_AudioSpec wav_spec;
+Uint32 wav_length;
+Uint8 *wav_buffer;
+
+/* Load the WAV */
+if( SDL_LoadWAV("test.wav", &wav_spec, &wav_buffer, &wav_length) == NULL ){
+  fprintf(stderr, "Could not open test.wav: %s\n", SDL_GetError());
+  exit(-1);
+}
+.
+.
+.
+/* Do stuff with the WAV */
+.
+.
+/* Free It */
+SDL_FreeWAV(wav_buffer);

SDL_LockSurface

Name

SDL_LockSurface -- Lock a surface for directly access.

Synopsis

#include "SDL.h"

int SDL_LockSurface(SDL_Surface *surface);

Description

SDL_LockSurface sets up a surface for directly +accessing the pixels. Between calls to SDL_LockSurface +and SDL_UnlockSurface, you can write to and read from +surface->pixels, using the pixel format stored in +surface->format. Once you are done accessing the +surface, you should use SDL_UnlockSurface to release it.

Not all surfaces require locking. +If SDL_MUSTLOCK(surface) +evaluates to 0, then you can read and write to the +surface at any time, and the pixel format of the surface will not change.

No operating system or library calls should be made between lock/unlock +pairs, as critical system locks may be held during this time.

It should be noted, that since SDL 1.1.8 surface locks are recursive. This means that you can lock a surface multiple times, but each lock must have a match unlock. +

    .
+    .
+    SDL_LockSurface( surface );
+    .
+    /* Surface is locked */
+    /* Direct pixel access on surface here */
+    .
+    SDL_LockSurface( surface );
+    .
+    /* More direct pixel access on surface */
+    .
+    SDL_UnlockSurface( surface );
+    /* Surface is still locked */
+    /* Note: Is versions < 1.1.8, the surface would have been */
+    /* no longer locked at this stage                         */
+    .
+    SDL_UnlockSurface( surface );
+    /* Surface is now unlocked */
+    .
+    .
+

Return Value

SDL_LockSurface returns 0, +or -1 if the surface couldn't be locked.

Structure Definition

typedef struct{
+  Uint8 type;
+  Uint8 button;

+} SDL_MouseButtonEvent;

Structure Data

typeSDL_MOUSEBUTTONDOWN or SDL_MOUSEBUTTONUP
buttonThe mouse button index (SDL_BUTTON_LEFT, SDL_BUTTON_MIDDLE, SDL_BUTTON_RIGHT)
stateSDL_PRESSED or SDL_RELEASED
x, yThe X/Y coordinates of the mouse at press/release time

Description

SDL_MouseButtonEvent is a member of the SDL_Event union and is used when an event of type SDL_MOUSEBUTTONDOWN or SDL_MOUSEBUTTONUP is reported.

When a mouse button press or release is detected then number of the button pressed (from 1 to 255, with 1 usually being the left button and 2 the right) is placed into button, the position of the mouse when this event occured is stored in the x and the y fields. Like SDL_KeyboardEvent, information on whether the event was a press or a release event is stored in both the type and state fields, but this should be obvious.

+} SDL_MouseMotionEvent;

Structure Data

typeSDL_MOUSEMOTION
stateThe current button state
x, yThe X/Y coordinates of the mouse
xrel, yrelRelative motion in the X/Y direction

Description

SDL_MouseMotionEvent is a member of the SDL_Event union and is used when an event of type SDL_MOUSEMOTION is reported.

Simply put, a SDL_MOUSEMOTION type event occurs when a user moves the mouse within the application window or when SDL_WarpMouse is called. Both the absolute (x and y) and relative (xrel and yrel) coordinates are reported along with the current button states (state). The button state can be interpreted using the SDL_BUTTON macro (see SDL_GetMouseState).

If the cursor is hidden (SDL_ShowCursor(0)) and the input is grabbed (SDL_WM_GrabInput(SDL_GRAB_ON)), then the mouse will give relative motion events even when the cursor reaches the edge fo the screen. This is currently only implemented on Windows and Linux/Unix-a-likes.

SDL_OpenAudio

Name

SDL_OpenAudio -- Opens the audio device with the desired parameters.

Synopsis

#include "SDL.h"

int SDL_OpenAudio(SDL_AudioSpec *desired, SDL_AudioSpec *obtained);

Description

This function opens the audio device with the desired parameters, and +returns 0 if successful, placing the actual hardware parameters in the +structure pointed to by obtained. If obtained is NULL, the audio +data passed to the callback function will be guaranteed to be in the +requested format, and will be automatically converted to the hardware +audio format if necessary. This function returns -1 if it failed +to open the audio device, or couldn't set up the audio thread.

To open the audio device a desired SDL_AudioSpec must be created. +

SDL_AudioSpec *desired;
+.
+.
+desired=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
+You must then fill this structure with your desired audio specifications.

desired->freq

The desired audio frequency in samples-per-second.

desired->format

The desired audio format (see SDL_AudioSpec)

desired->samples

The desired size of the audio buffer in samples. This number should be a power of two, and may be adjusted by the audio driver to a value more suitable for the hardware. Good values seem to range between 512 and 8192 inclusive, depending on the application and CPU speed. Smaller values yield faster response time, but can lead to underflow if the application is doing heavy processing and cannot fill the audio buffer in time. A stereo sample consists of both right and left channels in LR ordering. Note that the number of samples is directly related to time by the following formula: ms = (samples*1000)/freq

desired->callback

This should be set to a function that will be called when the audio device is ready for more data. It is passed a pointer to the audio buffer, and the length in bytes of the audio buffer. This function usually runs in a separate thread, and so you should protect data structures that it accesses by calling SDL_LockAudio and SDL_UnlockAudio in your code. The callback prototype is: +

void callback(void *userdata, Uint8 *stream, int len);
+userdata is the pointer stored in userdata field of the SDL_AudioSpec. stream is a pointer to the audio buffer you want to fill with information and len is the length of the audio buffer in bytes.

desired->userdata

This pointer is passed as the first parameter to the callback function.

SDL_OpenAudio reads these fields from the desired SDL_AudioSpec structure pass to the function and attempts to find an audio configuration matching your desired. As mentioned above, if the obtained parameter is NULL then SDL with convert from your desired audio settings to the hardware settings as it plays.

If obtained is NULL then the desired SDL_AudioSpec is your working specification, otherwise the obtained SDL_AudioSpec becomes the working specification and the desirec specification can be deleted. The data in the working specification is used when building SDL_AudioCVT's for converting loaded data to the hardware format.

SDL_OpenAudio calculates the size and silence fields for both the desired and obtained specifications. The size field stores the total size of the audio buffer in bytes, while the silence stores the value used to represent silence in the audio buffer

The audio device starts out playing silence when it's opened, and should be enabled for playing by calling SDL_PauseAudio(0) when you are ready for your audio callback function to be called. Since the audio driver may modify the requested size of the audio buffer, you should allocate any local mixing buffers after you open the audio device.

Examples

/* Prototype of our callback function */
+void my_audio_callback(void *userdata, Uint8 *stream, int len);
+
+/* Open the audio device */
+SDL_AudioSpec *desired, *obtained;
+SDL_AudioSpec *hardware_spec;
+
+/* Allocate a desired SDL_AudioSpec */
+desired=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
+
+/* Allocate space for the obtained SDL_AudioSpec */
+obtained=(SDL_AudioSpec *)malloc(sizeof(SDL_AudioSpec));
+
+/* 22050Hz - FM Radio quality */
+desired->freq=22050;
+
+/* 16-bit signed audio */
+desired->format=AUDIO_S16LSB;
+
+/* Large audio buffer reduces risk of dropouts but increases response time */
+desired->samples=8192;
+
+/* Our callback function */
+desired->callback=my_audio_callback;
+
+desired->userdata=NULL;
+
+/* Open the audio device */
+if ( SDL_OpenAudio(desired, obtained) < 0 ){
+  fprintf(stderr, "Couldn't open audio: %s\n", SDL_GetError());
+  exit(-1);
+}
+/* desired spec is no longer needed */
+free(desired);
+hardware_spec=obtained;

[RGBA]maskBinary mask used to retrieve individual color values
[RGBA]lossPrecision loss of each color component (2[RGBA]loss)

colorkeyPixel value of transparent pixels
alphaOverall surface alpha value

Description

A SDL_PixelFormat describes the format of the pixel data stored at the pixels field of a SDL_Surface. Every surface stores a SDL_PixelFormat in the format field.

If you wish to do pixel level modifications on a surface, then understanding how SDL stores its color information is essential.

8-bit pixel formats are the easiest to understand. Since its an 8-bit format, we have 8 BitsPerPixel and 1 BytesPerPixel. Since BytesPerPixel is 1, all pixels are represented by a Uint8 which contains an index into palette->colors. So, to determine the color of a pixel in a 8-bit surface: we read the color index from surface->pixels and we use that index to read the SDL_Color structure from surface->format->palette->colors. Like so: +

SDL_Surface *surface;
+SDL_PixelFormat *fmt;
+SDL_Color *color;
+Uint8 index;
+
+.
+.
+
+/* Create surface */
+.
+.
+fmt=surface->format;
+
+/* Check the bitdepth of the surface */
+if(fmt->BitsPerPixel!=8){
+  fprintf(stderr, "Not an 8-bit surface.\n");
+  return(-1);
+}
+
+/* Lock the surface */
+SDL_LockSurface(surface);
+
+/* Get the topleft pixel */
+index=*(Uint8 *)surface->pixels;
+color=fmt->palette->colors[index];
+
+/* Unlock the surface */
+SDL_UnlockSurface(surface);
+printf("Pixel Color-> Red: %d, Green: %d, Blue: %d. Index: %d\n",
+          color->r, color->g, color->b, index);
+.
+.

Pixel formats above 8-bit are an entirely different experience. They are +considered to be "TrueColor" formats and the color information is stored in the +pixels themselves, not in a palette. The mask, shift and loss fields tell us +how the color information is encoded. The mask fields allow us to isolate each +color component, the shift fields tell us the number of bits to the right of +each component in the pixel value and the loss fields tell us the number of +bits lost from each component when packing 8-bit color component in a pixel. +

/* Extracting color components from a 32-bit color value */
+SDL_PixelFormat *fmt;
+SDL_Surface *surface;
+Uint32 temp, pixel;
+Uint8 red, green, blue, alpha;

SDL_PumpEvents

Name

SDL_PumpEvents -- Pumps the event loop, gathering events from the input devices.

Synopsis

#include "SDL.h"

void SDL_PumpEvents(void);

Description

Pumps the event loop, gathering events from the input devices.

SDL_PumpEvents gathers all the pending input information from devices and places it on the event queue. Without calls to SDL_PumpEvents no events would ever be placed on the queue. Often calls the need for SDL_PumpEvents is hidden from the user since SDL_PollEvent and SDL_WaitEvent implicitly call SDL_PumpEvents. However, if you are not polling or waiting for events (e.g. your filtering them), then you must call SDL_PumpEvents to force an event queue update.

Note: You can only call this function in the thread that set the video mode.

Name

SDL_PushEvent -- Pushes an event onto the event queue

Synopsis

#include "SDL.h"

int SDL_PushEvent(SDL_Event *event);

Description

The event queue can actually be used as a two way communication channel. Not only can events be read from the queue, but the user can also push their own events onto it. event is a pointer to the event structure you wish to push onto the queue.

Note: Pushing device input events onto the queue doesn't modify the state of the device within SDL.

Return Value

Returns 0 on success or -1 if the event couldn't be pushed.

Examples

See SDL_Event.

Synopsis

Description

SDL_Quit shuts down all SDL subsystems and frees the resources allocated to them. This should always be called before you exit. For the sake of simplicity you can set SDL_Quit as your atexit call, like: +

SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO);
+atexit(SDL_Quit);
+.
+.

Note: While using atexit maybe be fine for small programs, more advanced users should shut down SDL in their own cleanup code. Plus, using atexit in a library is a sure way to crash dynamically loaded code

Structure Data

Description

SDL_QuitEvent is a member of the SDL_Event union and is used whan an event of type SDL_QUIT is reported.

As can be seen, the SDL_QuitEvent structure serves no useful purpose. The event itself, on the other hand, is very important. If you filter out or ignore a quit event then it is impossible for the user to close the window. On the other hand, if you do accept a quit event then the application window will be closed, and screen updates will still report success event though the application will no longer be visible.

Note: The macro SDL_QuitRequested will return non-zero if a quit event is pending

SDL_SetAlpha

Name

SDL_SetAlpha -- Adjust the alpha properties of a surface

Synopsis

#include "SDL.h"

int SDL_SetAlpha(SDL_Surface *surface, Uint32 flag, Uint8 alpha);

Description

Note: This function and the semantics of SDL alpha blending have changed since version 1.1.4. Up until version 1.1.5, an alpha value of 0 was considered opaque and a value of 255 was considered transparent. This has now been inverted: 0 (SDL_ALPHA_TRANSPARENT) is now considered transparent and 255 (SDL_ALPHA_OPAQUE) is now considered opaque.

SDL_SetAlpha is used for setting the per-surface alpha +value and/or enabling and disabling alpha blending.

Thesurface parameter specifies which surface whose alpha +attributes you wish to adjust. flags is used to specify +whether alpha blending should be used (SDL_SRCALPHA) and +whether the surface should use RLE acceleration for blitting +(SDL_RLEACCEL). flags can be an OR'd +combination of these two options, one of these options or 0. If +SDL_SRCALPHA is not passed as a flag then all alpha +information is ignored when blitting the surface. The +alpha parameter is the per-surface alpha value; a +surface need not have an alpha channel to use per-surface alpha and blitting +can still be accelerated with SDL_RLEACCEL.

Note: The per-surface alpha value of 128 is considered a special case and +is optimised, so it's much faster than other per-surface values.

Alpha effects surface blitting in the following ways:

RGBA->RGB with SDL_SRCALPHA

The source is alpha-blended with the destination, using the alpha channel. SDL_SRCCOLORKEY and the per-surface alpha are ignored.

RGBA->RGB without SDL_SRCALPHA

The RGB data is copied from the source. The source alpha channel and the per-surface alpha value are ignored.

RGB->RGBA with SDL_SRCALPHA

The source is alpha-blended with the destination using the per-surface alpha +value. If SDL_SRCCOLORKEY is set, only the pixels not +matching the colorkey value are copied. The alpha channel of the copied pixels +is set to opaque.

RGB->RGBA without SDL_SRCALPHA

The RGB data is copied from the source and the alpha value of the copied pixels +is set to opaque. If SDL_SRCCOLORKEY is set, only the pixels +not matching the colorkey value are copied.

RGBA->RGBA with SDL_SRCALPHA

The source is alpha-blended with the destination using the source alpha +channel. The alpha channel in the destination surface is left untouched. +SDL_SRCCOLORKEY is ignored.

RGBA->RGBA without SDL_SRCALPHA

The RGBA data is copied to the destination surface. If SDL_SRCCOLORKEY is set, only the pixels not matching the colorkey value are copied.

RGB->RGB with SDL_SRCALPHA

The source is alpha-blended with the destination using the per-surface alpha value. If SDL_SRCCOLORKEY is set, only the pixels not matching the colorkey value are copied.

RGB->RGB without SDL_SRCALPHA

The RGB data is copied from the source. If SDL_SRCCOLORKEY is set, only the pixels not matching the colorkey value are copied.

Note: Note that RGBA->RGBA blits (with SDL_SRCALPHA set) keep the alpha +of the destination surface. This means that you cannot compose two arbitrary +RGBA surfaces this way and get the result you would expect from "overlaying" +them; the destination alpha will work as a mask.

Also note that per-pixel and per-surface alpha cannot be combined; +the per-pixel alpha is always used if available

Return Value

This function returns 0, or +-1 if there was an error.

SDL_SetClipRect

Name

SDL_SetClipRect -- Sets the clipping rectangle for a surface.

Synopsis

#include "SDL.h"

void SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect);

Description

Sets the clipping rectangle for a surface. When this surface is the +destination of a blit, only the area within the clip rectangle will be +drawn into.

The rectangle pointed to by rect will be +clipped to the edges of the surface so that the clip rectangle for a +surface can never fall outside the edges of the surface.

If rect is NULL the clipping +rectangle will be set to the full size of the surface.

SDL_SetColorKey

Name

SDL_SetColorKey -- Sets the color key (transparent pixel) in a blittable surface and +RLE acceleration.

Synopsis

#include "SDL.h"

int SDL_SetColorKey(SDL_Surface *surface, Uint32 flag, Uint32 key);

Description

Sets the color key (transparent pixel) in a blittable surface and enables or + disables RLE blit acceleration.

RLE acceleration can substantially speed up blitting of images with large +horizontal runs of transparent pixels (i.e., pixels that match the +key value). The key must be of the same pixel format as the surface, SDL_MapRGB is often useful for obtaining an acceptable value.

If flag is SDL_SRCCOLORKEY then +key is the transparent pixel value in the source image of a +blit.

If flag is OR'd with +SDL_RLEACCEL then the surface will be draw using RLE +acceleration when drawn with +SDL_BlitSurface. The surface will +actually be encoded for RLE acceleration the first time +SDL_BlitSurface or +SDL_DisplayFormat is called on the +surface.

If flag is 0, this function clears +any current color key.

Return Value

This function returns 0, or +-1 if there was an error.

SDL_SetColors

Name

SDL_SetColors -- Sets a portion of the colormap for the given 8-bit surface.

Synopsis

#include "SDL.h"

int SDL_SetColors(SDL_Surface *surface, SDL_Color *colors, int firstcolor, int ncolors);

Description

Sets a portion of the colormap for the given 8-bit surface.

When surface is the surface associated with the current +display, the display colormap will be updated with the requested colors. If +SDL_HWPALETTE was set in SDL_SetVideoMode flags, +SDL_SetColors will always return 1, +and the palette is guaranteed to be set the way you desire, even if the window +colormap has to be warped or run under emulation.

The color components of a +SDL_Color +structure are 8-bits in size, giving you a total of 2563 +=16777216 colors.

Palettized (8-bit) screen surfaces with the SDL_HWPALETTE +flag have two palettes, a logical palette that is used for mapping blits +to/from the surface and a physical palette (that determines how the +hardware will map the colors to the display). SDL_SetColors +modifies both palettes (if present), and is equivalent to calling +SDL_SetPalette with the +flags set to +(SDL_LOGPAL | SDL_PHYSPAL).

Return Value

If surface is not a palettized surface, this function +does nothing, returning 0. If all of the colors were set +as passed to SDL_SetColors, it will return +1. If not all the color entries were set exactly as +given, it will return 0, and you should look at the +surface palette to determine the actual color palette.

Example

/* Create a display surface with a grayscale palette */
+SDL_Surface *screen;
+SDL_Color colors[256];
+int i;
+.
+.
+.
+/* Fill colors with color information */
+for(i=0;i<256;i++){
+  colors[i].r=i;
+  colors[i].g=i;
+  colors[i].b=i;
+}
+
+/* Create display */
+screen=SDL_SetVideoMode(640, 480, 8, SDL_HWPALETTE);
+if(!screen){
+  printf("Couldn't set video mode: %s\n", SDL_GetError());
+  exit(-1);
+}
+
+/* Set palette */
+SDL_SetColors(screen, colors, 0, 256);

Name

SDL_SetEventFilter -- Sets up a filter to process all events before they are posted +to the event queue.

Synopsis

#include "SDL.h"

void SDL_SetEventFilter(SDL_EventFilter filter);

Description

This function sets up a filter to process all events before they are posted +to the event queue. This is a very powerful and flexible feature. The filter +is prototyped as: +

typedef int (*SDL_EventFilter)(const SDL_Event *event);
+If the filter returns 1, then the event will be +added to the internal queue. If it returns 0, +then the event will be dropped from the queue. This allows selective +filtering of dynamically.

There is one caveat when dealing with the SDL_QUITEVENT event type. The +event filter is only called when the window manager desires to close the +application window. If the event filter returns 1, then the window will +be closed, otherwise the window will remain open if possible. +If the quit event is generated by an interrupt signal, it will bypass the +internal queue and be delivered to the application at the next event poll.

Note: Events pushed onto the queue with SDL_PushEvent or SDL_PeepEvents do not get passed through the event filter.

Note: Be Careful! The event filter function may run in a different thread so be careful what you do within it.

SDL_SetPalette

Name

SDL_SetPalette -- Sets the colors in the palette of an 8-bit surface.

Synopsis

#include "SDL.h"

int SDL_SetPalette(SDL_Surface *surface, int flags, SDL_Color *colors, int firstcolor, int ncolors);

Description

Sets a portion of the palette for the given 8-bit surface.

Palettized (8-bit) screen surfaces with the +SDL_HWPALETTE flag have two palettes, a logical +palette that is used for mapping blits to/from the surface and a +physical palette (that determines how the hardware will map the colors +to the display). SDL_BlitSurface +always uses the logical palette when blitting surfaces (if it has to +convert between surface pixel formats). Because of this, it is often +useful to modify only one or the other palette to achieve various +special color effects (e.g., screen fading, color flashes, screen dimming).

This function can modify either the logical or physical palette by +specifing SDL_LOGPAL or +SDL_PHYSPALthe in the flags +parameter.

When surface is the surface associated with the current +display, the display colormap will be updated with the requested colors. If +SDL_HWPALETTE was set in SDL_SetVideoMode flags, +SDL_SetPalette will always return 1, +and the palette is guaranteed to be set the way you desire, even if the window +colormap has to be warped or run under emulation.

The color components of a +SDL_Color structure +are 8-bits in size, giving you a total of +2563=16777216 colors.

Return Value

If surface is not a palettized surface, this function +does nothing, returning 0. If all of the colors were set +as passed to SDL_SetPalette, it will return +1. If not all the color entries were set exactly as +given, it will return 0, and you should look at the +surface palette to determine the actual color palette.

Example

        /* Create a display surface with a grayscale palette */
+        SDL_Surface *screen;
+        SDL_Color colors[256];
+        int i;
+        .

Name

SDL_SetTimer -- Set a callback to run after the specified number of milliseconds has +elapsed.

Synopsis

#include "SDL.h"

int SDL_SetTimer(Uint32 interval, SDL_TimerCallback callback);

Callback

/* Function prototype for the timer callback function */ +typedef Uint32 (*SDL_TimerCallback)(Uint32 interval);

Description

Set a callback to run after the specified number of milliseconds has +elapsed. The callback function is passed the current timer interval +and returns the next timer interval. If the returned value is the +same as the one passed in, the periodic alarm continues, otherwise a +new alarm is scheduled.

To cancel a currently running timer, call +SDL_SetTimer(0, NULL);

The timer callback function may run in a different thread than your +main constant, and so shouldn't call any functions from within itself.

The maximum resolution of this timer is 10 ms, which means that if +you request a 16 ms timer, your callback will run approximately 20 ms +later on an unloaded system. If you wanted to set a flag signaling +a frame update at 30 frames per second (every 33 ms), you might set a +timer for 30 ms (see example below).

If you use this function, you need to pass SDL_INIT_TIMER +to SDL_Init().

Note: This function is kept for compatibility but has been superseded +by the new timer functions +SDL_AddTimer and +SDL_RemoveTimer which support +multiple timers.

Examples

SDL_SetTimer((33/10)*10, my_callback);

Synopsis

SDL_Surface *SDL_SetVideoMode(int width, int height, int bpp, Uint32 flags);

Description

Set up a video mode with the specified width, height and bits-per-pixel.

If bpp is 0, it is treated as the +current display bits per pixel.

The flags parameter is the same as the flags field of the SDL_Surface structure. OR'd combinations of the following values are valid.

SDL_SWSURFACECreate the video surface in system memory
SDL_HWSURFACECreate the video surface in video memory
SDL_ASYNCBLITEnables the use of asynchronous to the display surface. This will usually slow down blitting on single CPU machines, but may provide a speed increase on SMP systems.
SDL_ANYFORMATNormally, if a video surface of the requested depth (bpp) is not available, SDL will emulate one with a shadow surface. Passing SDL_ANYFORMAT prevents this and causes SDL to use the video surface, regardless of its depth.
SDL_HWPALETTEGive SDL exclusive palette access. Without this flag you may not always get the the colors you request with SDL_SetColors.
SDL_DOUBLEBUFEnable double buffering; only valid with SDL_HWSURFACE. Calling SDL_Flip will flip the buffers and update the screen. If double buffering could not be enabled then SDL_Flip will just perform a SDL_UpdateRect on the entire screen.
SDL_FULLSCREENSDL will attempt to use a fullscreen mode
SDL_OPENGLCreate an OpenGL rendering context. You should have previously set OpenGL video attributes with SDL_GL_SetAttribute.
SDL_OPENGLBLITCreate an OpenGL rendering context, like above, but allow normal blitting operations.
SDL_RESIZABLECreate a resizable window. When the window is resized by the user a SDL_VIDEORESIZE event is generated and SDL_SetVideoMode can be called again with the new size.
SDL_NOFRAMEIf possible, SDL_NOFRAME causes SDL to create a window with no title bar or frame decoration. Fullscreen modes automatically have this flag set.

Note: Whatever flags SDL_SetVideoMode could satisfy are set in the flags member of the returned surface.

Return Value

The framebuffer surface, or NULL if it fails.

Name

SDL_UpdateRects -- Makes sure the given list of rectangles is updated on the given screen.

Synopsis

#include "SDL.h"

void SDL_UpdateRects(SDL_Surface *screen, int numrects, SDL_Rect *rects);

Description

Makes sure the given list of rectangles is updated on the given screen. +The rectangles must all be confined within the screen boundaries (no +clipping is done).

This function should not be called while screen is +locked.

Note: It is adviced to call this function only once per frame, since each +call has some processing overhead. This is no restriction since you +can pass any number of rectangles each time.

The rectangles are not automatically merged or checked for overlap. In +general, the programmer can use his knowledge about his particular +rectangles to merge them in an efficient way, to avoid overdraw.

Synopsis

int SDL_VideoModeOK(int width, int height, int bpp, Uint32 flags);

Description

SDL_VideoModeOK returns 0 +if the requested mode is not supported under any bit depth, or returns the +bits-per-pixel of the closest available mode with the given width, height and requested surface flags (see SDL_SetVideoMode).

The bits-per-pixel value returned is only a suggested mode. You can usually request and bpp you want when setting the video mode and SDL will emulate that color depth with a shadow video surface.

+.
+.
+printf("Checking mode 640x480@16bpp.\n");

SDL provides functions for creating threads, mutexes, semphores and condition variables.

In general, you must be very aware of concurrency and data integrity issues +when writing multi-threaded programs. Some good guidelines include: +

  • Don't call SDL video/event functions from separate threads

  • Don't use any library functions in separate threads

  • Don't perform any memory management in separate threads

  • Lock global variables which may be accessed by multiple threads

  • Never terminate threads, always set a flag and wait for them to quit

  • Think very carefully about all possible ways your code may interact

Note: SDL's threading is not implemented on MacOS, due to that lack of preemptive thread support (eck!)

SDL provides several cross-platform functions for dealing with time. +It provides a way to get the current time, a way to wait a little while, +and a simple timer mechanism. These functions give you two ways of moving an +object every x milliseconds: + +

  • Use a timer callback function. This may have the bad effect that it runs in a seperate thread or uses alarm signals, but it's easier to implement.

  • Or you can get the number of milliseconds passed, and move the object if, for example, 30 ms passed.

SDL presents a very simple interface to the display framebuffer. The +framebuffer is represented as an offscreen surface to which you can write +directly. If you want the screen to show what you have written, call the update function which will +guarantee that the desired portion of the screen is updated.

Before you call any of the SDL video functions, you must first call +SDL_Init(SDL_INIT_VIDEO), which initializes the video +and events in the SDL library. Check the return code, which should be +0, to see if there were any errors in starting up.

If you use both sound and video in your application, you need to call +SDL_Init(SDL_INIT_AUDIO | SDL_INIT_VIDEO) before opening the +sound device, otherwise under Win32 DirectX, you won't be able to set +full-screen display modes.

After you have initialized the library, you can start up the video display in a +number of ways. The easiest way is to pick a common screen resolution and +depth and just initialize the video, checking for errors. You will probably +get what you want, but SDL may be emulating your requested mode and converting +the display on update. The best way is to +query, for the best +video mode closest to the desired one, and then +convert +your images to that pixel format.

SDL currently supports any bit depth >= 8 bits per pixel. 8 bpp formats are +considered 8-bit palettized modes, while 12, 15, 16, 24, and 32 bits per pixel +are considered "packed pixel" modes, meaning each pixel contains the RGB color +components packed in the bits of the pixel.

After you have initialized your video mode, you can take the surface that was +returned, and write to it like any other framebuffer, calling the update +routine as you go.

When you have finished your video access and are ready to quit your +application, you should call "SDL_Quit()" to shutdown the +video and events.

Introduction

This library is designed to make it easy to write games that run on Linux, +Win32 and BeOS using the various native high-performance media interfaces, +(for video, audio, etc) and presenting a single source-code level API to +your application. This is a fairly low level API, but using this, completely +portable applications can be written with a great deal of flexibility.

The library is loaded as a dynamically linked library on its native +platform, and is currently compiled natively for Linux, compiled for +Win32 using a Linux hosted GCC +cross-compilation +environment, and compiled using the EGCS C++ compiler under BeOS.

An introduction to SDL can be found online at: +http://www.libsdl.org/intro/

There are code examples on each of the main library pages, and there are +fully fleshed example C++ classes and programs in the examples archive, +available on the +SDL download page.

For an introduction to basic multi-media programming concepts, you might try +some of the following links: +

Enjoy!
