public var tween:mx.effects:Tween| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
The Tween object, which determines the animation.
To create an effect, you must create a Tween instance
in the override of the EffectInstance.play() method
and assign it to the tween property.
Use the createTween() method to create your Tween object.
TweenEffectInstance | () | Constructor |
createTween | () | method |
protected function createTween(listener:Object, startValue:Object, endValue:Object, duration:Number = -1, minFps:Number = -1):mx.effects:Tween| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Creates a Tween instance,
assigns it the start, end, and duration values. If an easing function has
been specified, then it is assigned to the Tween instance. The Tween instance is assigned
event listeners for the TweenEvents: tweenStart, tweenUpdate,
and tweenEnd.
Typically, you call this method from your override of
the EffectInstance.play() method
which effectively starts the animation timer.
Parameters
listener:Object — Object that is notified at each interval
of the animation. You typically pass the this
keyword as the value.
The listener must define the
onTweenUpdate() method and optionally the
onTweenEnd() method.
The onTweenUpdate() method is invoked for each interval of the animation,
and the onTweenEnd() method is invoked just after the animation finishes.
| |
startValue:Object — Initial value(s) of the animation.
Either a number or an Array of numbers.
If a number is passed, the Tween interpolates
between this number and the number passed
in the endValue parameter.
If an Array of numbers is passed,
each number in the Array is interpolated.
| |
endValue:Object — Final value(s) of the animation.
The type of this argument must match the startValue
parameter.
| |
duration:Number (default = -1) | |
minFps:Number (default = -1)onTweenUpdate() method should be called every second.
The tween code tries to call the onTweenUpdate()
method as frequently as possible (up to 100 times per second).
However, if the frequency falls below minFps,
the duration of the animation automatically increases.
As a result, an animation that temporarily freezes
(because it is not getting any CPU cycles) begins again
where it left off, instead of suddenly jumping ahead.
|
mx.effects:Tween — The newly created Tween instance.
|
end | () | method |
override public function end():void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Interrupts an effect that is currently playing,
and immediately jumps to the end of the effect.
Calls the Tween.endTween() method
on the tween property.
This method implements the method of the superclass.
If you create a subclass of TweenEffectInstance, you can optionally override this method.
The effect dispatches the effectEnd event.

onTweenEnd | () | method |
public function onTweenEnd(value:Object):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Callback method that is called when the target should be updated
by the effect for the last time.
The Tween class passes Tween.endValue as the value
of the value argument.
The value argument can be either a Number
or an Array of Numbers.
Overriding this function is optional.
You must also call the super version of this method
from the end of your override, super.onTweenEnd(val),
after your logic.
Parameters
value:Object — The value of the value argument
is an interpolated value determined by the
Tween.startValue property,
Tween.endValue property, and interpolation function
specified by the implementation of the effect in its
play() method.
The play() method uses these values to create
a Tween object that plays the effect over a time period.
The value argument can be either a Number
or an Array of Numbers.
|
onTweenUpdate | () | method |
public function onTweenUpdate(value:Object):void| Language Version: | ActionScript 3.0 |
| Product Version: | Flex 3 |
| Runtime Versions: | Flash Player 9, AIR 1.1 |
Callback method that is called when the target should be updated
by the effect.
The Tween class uses the easing function and the
Tween.startValue, Tween.endValue
and Tween.duration properties to calculate
the value of the value argument.
The value argument can be either a Number
or an Array of Numbers.
All subclasses must override this method. It is not necessary to call the super version of this function when overriding this method.
Parameters
value:Object — The value of the value argument
is an interpolated value determined by the
Tween.startValue property,
Tween.endValue property, and interpolation function
specified by the implementation of the effect in its
play() method.
The play() method uses these values to create
a Tween object that plays the effect over a time period.
The value argument can be either a Number
or an Array of Numbers.
