<source lang="java">

package

{

}
}
}
</source>

==Animating with Pure ActionScript==



<source lang="java">

package
{
import flash.display.*;
import flash.events.TimerEvent;
import flash.utils.Timer;
public class Main extends Sprite
{
protected var myShape:DisplayObject;
public function Main()
{
var fps:int = 60;
var mspf:int = Math.round(1 / fps * 1000);
var t:Timer = new Timer(mspf);

myShape = getChildAt(0);
}
protected function onTimer(event:TimerEvent):void

==Animation and Speed==



<source lang="java">

package
{

==A timer function-based animation==



<source lang="java">

package {

==Moving an Object==

==Programmatic Animation==
