Module raylib.reasings

reasings - raylib easings library, based on Robert Penner library

Useful easing functions for values animation

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 any unit measure, but same unit as duration) b = starting value to interpolate c = the total change in value of b that needs to occur d = total time it should take to complete (duration)

Example

int currentTime = 0; int duration = 100; float startPositionX = 0.0f; float finalPositionX = 30.0f; float currentPositionX = startPositionX;

while (currentPositionX < finalPositionX) { currentPositionX = EaseSineIn(currentTime, startPositionX, finalPositionX - startPositionX, duration); currentTime++; }
