reasings - raylib easings library, based on Robert Penner library

Useful easing functions for values animation

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:

import src/reasings
var currentTime = 0
let duration = 100
let startPositionX: float32 = 0.0
let finalPositionX: float32 = 30.0
var currentPositionX = startPositionX

while currentPositionX < finalPositionX:
  currentPositionX = linearIn(currentTime.float32, startPositionX,
      finalPositionX - startPositionX, duration.float32)
  inc currentTime
