Moving a Movie Clip

[Hurdarr]

Try something like this:

package
{
    import flash.display.Sprite;
    import flash.events.KeyboardEvent;
    import flash.ui.Keyboard;
    
    public class KeyCodes extends Sprite
    {
        protected var ball:Sprite;
        
        public function KeyCodes()
        {
            init();
        }
        protected function init():void
        {
            ball = new Sprite();
            addChild(ball);
            ball.graphics.beginFill(0xff0000);
            ball.graphics.drawCircle(0, 0, 40);
            ball.graphics.endFill();
            ball.x = stage.stageWidth / 2;
            ball.y = stage.stageHeight / 2;
            stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyboardEvent);
        }
        protected function onKeyboardEvent(event:KeyboardEvent):void
        {
            switch(event.keyCode)
            {
                case Keyboard.UP : ball.y -= 10;
                break;
                
                case Keyboard.DOWN : ball.y += 10;
                break;
                
                case Keyboard.LEFT : ball.x -= 10;
                break;
                
                case Keyboard.RIGHT : ball.x += 10;
                break;
                
                default : break;
            }
        }
    }
} 

Good luck.

Thanks for the input, but I get the following error: 1037: Packages cannot be nested.
