AS 3 getBounds

programming flash
1

Can anyone of you guys help me out with this one?

The following piece of code works in the timeline:

var ball:Sprite = new Sprite;
addChild(ball);
ball.graphics.beginFill(Math.random()*0xff0000);
ball.graphics.drawCircle(0,0,10);
ball.graphics.endFill();

var speedX = +10;
var speedY = +10;

addEventListener(Event.ENTER_FRAME, enterFrameHandler);

function enterFrameHandler(event:Event):void
{
ball.x += speedX;
ball.y += speedY;
var bounds:Rectangle = ball.getBounds(stage);

if (bounds.left < 0 || bounds.right > stage.stageWidth)
{
    speedX *=  -1;
}


if (bounds.top < 0 || bounds.bottom > stage.stageHeight)
{
    speedY *=  -1;
}

}

I am trying to achieve a similar result by using an external file but I can’t figure out how to do it.
Here is the AS 3 file I’m having a problem with:

package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.geom.Rectangle;

public class Ball extends Sprite
{
    private var ball:Sprite = new Sprite  ;
    private var speedX:int = +10;
    private var speedY:int = -10;


    public function Ball()
    {


        addChild(ball);
        ball.graphics.beginFill(Math.random()*0xffffff);
        ball.graphics.drawCircle(0,0,20);
        ball.graphics.endFill();
        addEventListener(Event.ENTER_FRAME, enterFrameHandler);


    }


    private function enterFrameHandler(event:Event):void
    {
        ball.x += speedX;
        ball.y += speedY; 
        
        var bounds:Rectangle = ball.getBounds(stage);
        
        if (bounds.left < 0 || bounds.right > stage.stageWidth)
        {
            speedX *=  -1;
        }


        if (bounds.top < 0 || bounds.bottom > stage.stageHeight)
        {
            speedY *=  -1;
        }
                    
    }


}

}

Is the stage accessed differently with the getBounds method in an external file than in the timeline?

I’d really appreciate it if anyone can help me out with this one.

Thanks.
