InheritanceSteppedEase Inheritance Ease Inheritance Object

Most easing equations give a smooth, gradual transition between the start and end values, but SteppedEase provides an easy way to define a specific number of steps that the transition should take. For example, if mc.x is 0 and you want to tween it to 100 with 5 steps (20, 40, 60, 80, and 100) over the course of 2 seconds, you'd do:
TweenLite.to(mc, 2, {x:100, ease:SteppedEase.config(5)});
//or create an instance directly
var steppedEase = new SteppedEase(5);
TweenLite.to(mc, 3, {y:300, ease:steppedEase});

Note: SteppedEase is optimized for use with the GreenSock tweenining platform, so it isn't intended to be used with other engines. Specifically, its easing equation always returns values between 0 and 1.

Method Detail
config()method
public static function config(steps:int):SteppedEase

Permits customization of the ease (defining a number of steps).

Parameters

steps:int — Number of steps between the start and the end values.

Returns
SteppedEase — new SteppedEase instance that is configured according to the parameters provided
getRatio()method 
override public function getRatio(p:Number):Number

Translates the tween's progress ratio into the corresponding ease ratio. This is the heart of the Ease, where it does all its work.

Parameters

p:Number — progress ratio (a value between 0 and 1 indicating the progress of the tween/ease)

Returns
Number — translated number
