==Animating a TextField horizontally to x-coordinate 300, timer version==

==Frame Rate"s Effect on Event.ENTER_FRAME Animations==



<source lang="java">

package {

==Timer event==



<source lang="java">

package {

==To eliminate unnecessary function calls, we unregister moveTextRight( ) for Event.ENTER_FRAME events.==



<source lang="java">

package{
import flash.display.*;
import flash.text.*;
import flash.events.*;
public class Main extends Sprite {
private var t:TextField = new TextField( );

public function Main ( ) {
t.text = "Hello";
t.autoSize = TextFieldAutoSize.LEFT;
addChild(t);

addEventListener(Event.ENTER_FRAME, moveTextRight);
}

public function moveTextRight (e:Event):void {
if (t.x <= 300) {
t.x += 10;
if (t.x > 300) {
t.x = 300;
}
} else {
removeEventListener(Event.ENTER_FRAME, moveTextRight);
}

}
}
}
