| Classe | public final class Animation |
| Ereditarietà | Animation  Object |
| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
This class defines the timing and value parts of the animation. Other code, either in effects or in application code, associates the animation with target objects and properties, such that the animated values produced by Animation class can then be applied to target objects and properties to actually cause these objects to animate.
When defining animation effects, you typically create an
instance of the Animate class, or of a subclass of Animate. This creates
an Animation instance in the play() method. The Animation instance
accepts start and end values, a duration, and optional parameters such as
easer and interpolator objects.
The Animation object calls event listeners at the start and end of the animation, when the animation repeats, and at regular update intervals during the animation. These calls pass values which the Animation instance calculated from the start and end values and the easer and interpolator objects. These values can then be used to set property values on target objects.

easer | proprietà |
easer:IEaser| Versione linguaggio: | ActionScript 3.0 |
| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
The easing behavior for this effect. This IEaser object is used to convert the elapsed fraction of the animation into an eased fraction, which is then used to calculate the value at that eased elapsed fraction.
A value of null means no easing is
used, which is equivalent to using a Linear ease, or
animation.easer = Linear.getInstance();.
Il valore predefinito è Sine(.5).

| Versione prodotto: | Flex 4 |
| Versioni runtime: | Flash Player 10, AIR 1.5 |
The interpolator used by the Animation instance
to calculate values between
the start and end values of the property.
By default, the class uses the NumberInterpolator class or,
in the case of the start and end values being arrays or Vectors,
by the MultiValueInterpolator class.
Interpolation of other data types, or
of Numbers that should be interpolated
differently, such as uint values that hold color
channel information, can be handled by supplying a different
interpolator.

Constructor.
The optional property, startValue, and

first keyframe, at time=0, and
endValue becomes the value of
the second keyframe, at the end of the animation.
