How can I reverse an easing function? So, I have an easing function (stored as a lambda), that takes a factor from between 0 and 1, and eases it accordingly. This is the cubic-out easing. { input -> 1 - (1 - input).pow(3.0) } In my animation class, when getting the value, if the animation is currently expanding, it simply eases the value, but when contracting, it minuses the value from 1 before easing it: easing.ease(1f - factor) What I want to do is to reverse the easing - like these two images (x represents the factor, t...
