Replace the sample table + Newton-Raphson + bisection search with the closed-form solver of bezier-easing 3.2: exact, no backward jump on steep curves such as (1, 0, 0, 1), and no sample array per easing. A ratio outside [0, 1] now saturates to 0 / 1 instead of going through the old search, which returned arbitrary values there.

Our code is ported from the original ActionScript 3.0 version of Starling Framework. Someone should probably do a similar PR on that project too (for folks using it with Adobe AIR, which is actually still maintained and updated, even though its sibling runtime Flash Player is discontinued): |

thanks @joshtynjala thanks for letting me know about that other codebase. I will add it in my list of libs to backport this into. cheers |

Hi, this is @gre, I'm the author of bezier-easing, which is also embedded in this project (
src/starling/animation/BezierEasing.hx). The library was recently improved with better performance and more reliability, and I wanted to backport the benefits here.This brings its 3.2 solver (closed-form, no sample table) to
BezierEasing.create:BezierEasing.create(1, 0, 0, 1)(0.4996)returned 0.348 instead of 0.431, so the tween went backwards for a frame.I checked it with
haxe --interpagainst the reference values and the old class.
