Method Detail
ease | () | method |
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.
|
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.
