The Bounce class implements easing functionality simulating gravity pulling on and bouncing the target object. The movement of the effect target accelerates toward the end value, and then bounces against the end value several times.

public function ease(fraction:Number):Number

Language Version : ActionScript 3.0
Product Version : Flex 4
Runtime Versions : Flash Player 10, AIR 1.5

Takes the fraction representing the elapsed duration of an animation (a value between 0.0 to 1.0) and returns a new elapsed value. This value is used to calculate animated property values. By changing the value of the elapsed fraction, you effectively change the animation of the property.

Parameters

fraction:Number — The elapsed fraction of an animation, from 0.0 to 1.0.

Returns
Number — The eased value for the elapsed time. Typically, this value should be constrained to lie between 0.0 and 1.0, although it is possible to return values outside of this range. Note that the results of returning such values are undefined, and depend on what kind of effects are using this eased value. For example, an object moving in a linear fashion can have positions calculated outside of its start and end point without a problem, but other value types (such as color) may not result in desired effects if they use time values that cause them to surpass their endpoint values.
