Hi

I’m always asking stupid questions, so I thought I’d give something back,

When you add a sprite to the screen it will Tween to position. Think it works because of event Bubbling. 🙂

```auto
package {
    import flash.display.Sprite;
    import flash.events.Event;
    import fl.motion.Tweenables;
    import fl.transitions.Tween;
    import fl.transitions.easing.*;
    import fl.transitions.TweenEvent;
    
    public class bubble extends Sprite{
    
        public function bubble(){
            
            var b1:Sprite = new Sprite();
            b1.graphics.beginFill(0xff0000);
            b1.graphics.drawRoundRect(10,10,100,60,10,10);
            b1.graphics.endFill();
            b1.name = "b1";
            addChild(b1);
            
            addEventListener(Event.ADDED, addChildEvent);
            }
        
        private function addChildEvent(event:Event):void {
            var t:Tween = new Tween(event.target,Tweenables.X, Elastic.easeOut, event.target.x-100, 0, 3, true);
            }    
    }
    
}

```
