According to this thread How to do an operation on a variable and assign it that new value for easing calculations? - #27 by absoluterookie with the help of you wonderul people i’ll give some back
Im a rookie. So this functions aren’t ment for pros, because they do way better.
But for those who still interested, here you go
fun backEaseInOut(e: Float, t: Float=0f, n: Float=100f, r: Float=100f):Float {
