public function ease(fraction:Number):Number

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.

參數

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

傳回值

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.
