* This header uses:
* #define EASINGS_STATIC_INLINE // Inlines all functions code, so it runs faster.
* // This requires lots of memory on system.
* How to use:
* The four inputs t,b,c,d are defined as follows:
* t = current time in milliseconds
* b = starting position in only one dimension [X || Y || Z] your choice
* c = the total change in value of b that needs to occur
* d = total time it should take to complete
*
* Example:
* float speed = 1.f;
* float currentTime = 0.f;
* float currentPos[2] = {0,0};
* float finalPos[2] = {1,1};
* float startPosition[2] = currentPos;//x,y positions
* while(currentPos[0] < finalPos[0])
* currentPos[0] = EaseSineIn(currentTime, startPosition[0], startPosition[0]-finalPos[0], speed);
* currentPos[1] = EaseSineIn(currentTime, startPosition[1], startPosition[1]-finalPos[0], speed);
* currentTime += diffTime();
