CustomEase.create( ID:String, data:String ) : CustomEase

Creates a CustomEase instance


ID: String

An ID (name) that can be used to identify this CustomEase instance, like "hop"

data: String

The string describing the easing curve, like "M0,0 C0,0 0.056,0.442 0.175,0.442 0.294,0.442 0.332,0 0.332,0 0.332,0 0.414,1 0.671,1 0.991,1 1,0 1,0". This can be SVG path data containing “M”, “C”, “S”, “L”, or “Z” commands, or it can be a string containing 4 numbers from CSS cubic-bezier() data like from cubic-bezier.com. Typically the values are normalized (0-1) but if not, they’ll be normalized internally.

Returns : CustomEase

Returns a new CustomEase instance


Creates a CustomEase instance and associates it with a particular ID (name) that can be used later in your animation code.

//create a CustomEase with an ID of "hop"
CustomEase.create("hop", "M0,0 C0,0 0.056,0.445 0.175,0.445 0.294,0.445 0.332,0 0.332,0 0.332,0 0.414,1 0.671,1 0.991,1 1,0 1,0");

//then, in your tween you can reference the ID for the ease:
TweenMax.to(element, 1, {y:-100, ease:"hop"});

We strongly recommend creating the CustomEase(s) when your page/app initially loads (rather than directly in each tween) in order to maximize performance and readability. You then reference it by ID in the tweening code. When an ease is created, it must parse the points and do various calculations to prepare for blisteringly fast runtime performance during the animation, so front-loading those calculations when your page/app loads is typically best.
