The Animation class defines an animation that happens between the start and end values of a property over a specified period of time. The animation can be a change in position, such as performed by the Move effect; a change in size, as performed by the Resize effect; a change in visibility, as performed by the Fade effect; or other types of animations used by effects or run directly with the Animation class.

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.

ActionScript 3.0

Produktversion:

Flex 4

Körningsmiljöversioner:

Flash Player 10, AIR 1.5

The current fraction elapsed in the animation, after easing has been applied. This value is between 0 and 1. An animation 'cycle' is defined as a single repetition of the animation, where the repeatCount property defines the number of cycles that will be played.

ActionScript 3.0

Produktversion:

Flex 4

Körningsmiljöversioner:

Flash Player 10, AIR 1.5

The current millisecond position in the current cycle animation. This value is between 0 and duration. An animation 'cycle' is defined as a single repetition of the animation, where the repeatCount property defines the number of cycles that will be played. Use the seek() method to change the position of the animation.

Implementering
public function get cycleTime():Number

duration

egenskap

public var duration:Number = 500

Språkversion:

ActionScript 3.0

Produktversion:

Standardvärdet är 500.

easer

egenskap

easer:IEaser

Språkversion:

ActionScript 3.0

Produktversion:

Flex 4

Körningsmiljöversioner:

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();.

Standardvärdet är Sine(.5).

Implementering
public function get easer():IEaser
public function set easer(value:IEaser):void

interpolator

egenskap

public var interpolator:IInterpolator = null

Språkversion:

ActionScript 3.0

Produktversion:

Flex 4

Körningsmiljöversioner:

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.

Språkversion:

ActionScript 3.0

Produktversion:

Flex 4

Körningsmiljöversioner:

Constructor. The optional property, startValue, and endValue parameters define a simple animation with a single MotionPath object with two Keyframes. If either value is non-null, startValue becomes the value of the first keyframe, at time=0, and endValue becomes the value of the second keyframe, at the end of the animation.

Parametrar

	`duration:Number` (default = `500`) — The length of the animation, in milliseconds.

	`property:String` (default = `null`) — The property to animate.

	`startValue:Object` (default = `null`) — The initial value of the property.

	`endValue:Object` (default = `null`) — The final value of the property.
