This is a crosspost from my UE4 research thread.
Blueprint Easing Function Library
I could not resist spending a few hours implementing an easing library. I think I used pretty much every easing resource available on the web for reference. I don’t take credit for the math, only the implementation.
The functions use an input Alpha value, expecting a value between 0.0-1.0. Output is a value that starts/end at 0.0/1.0 with some overdrive as seen in the video. The only exception are the elastic functions which also has a parameter for frequency.
The function library can be downloaded below for UE4 4.3.0. Instructions can be found inside the ReadMe file.
