Repeating an animation using the AnimateProperties class in Flex and Flash Player 10
The following example shows how you can repeat a property animation in Flex with the beta Gumbo SDK and Flash Player 10 using the AnimateProperties class and repeatCount property.
Full code after the jump.
To use the following code, you must have Flash Player 10 and a Flex Gumbo SDK installed in your Flex Builder 3. For more information on downloading and installing the Gumbo SDK into Flex Builder 3, see “Using the beta Gumbo SDK in Flex Builder 3″.
<?xml version="1.0" encoding="utf-8"?>
<!-- http://blog.flexexamples.com/2008/08/12/repeating-an-animation-using-the-animateproperties-class-in-flex-and-flash-player-10/ -->
<Application xmlns="http://ns.adobe.com/mxml/2009"
xmlns:mx="library:adobe/flex/halo"
layout="flex.layout.BasicLayout">
<Declarations>
<AnimateProperties id="animateProps"
repeatCount="{numericStepper.value}">
<propertyValuesList>
<PropertyValuesHolder property="rotationY"
values="[0, 360]" />
</propertyValuesList>
</AnimateProperties>
</Declarations>
<Script>
private function animateRotationY():void {
animateProps.stop();
animateProps.play([img]);
}
</Script>
<mx:HBox top="10" left="10">
<mx:NumericStepper id="numericStepper"
minimum="0"
maximum="10"
value="1" />
<Button label="Rotate y-axis"
click="animateRotationY();" />
</mx:HBox>
<mx:Image id="img"
source="@Embed('Fx.png')"
width="100"
height="100"
horizontalCenter="0"
verticalCenter="0" />
</Application>
View source is enabled in the following example.
You can also set the repeatCount property using ActionScript, as seen in the following example:

import flex.effects.PropertyValuesHolder;
private var animateProps:AnimateProperties;
private function init():void {
var rotYProp:PropertyValuesHolder;
rotYProp = new PropertyValuesHolder("rotationY", [0, 360]);
animateProps = new AnimateProperties();
animateProps.propertyValuesList = [rotYProp];
}
private function animateRotationY():void {
animateProps.stop();
animateProps.repeatCount = numericStepper.value;
animateProps.play([img]);
}
</Script>
<mx:HBox top="10" left="10">
<mx:NumericStepper id="numericStepper"
minimum="0"
maximum="10"

<Button label="Rotate y-axis"
click="animateRotationY();" />
</mx:HBox>
<mx:Image id="img"
source="@Embed('Fx.png')"
width="100"
height="100"
horizontalCenter="0"
verticalCenter="0" />
</Application>

Well, it looks like this code may have been affected by a recent API change. If you’re using Gumbo SDK 4.0.0.2810 or newer, it appears that the AnimateProperties class has been renamed to Animate.
“Thanks Chet!” :)
Peter

Peter
