Hi there, Im trying to make a load of bubbles appear as the mouse moves, which then tween to the top of the screen.  
Im using “mc\_tween2.as” class to help the tweening.

```auto
onMouseMove = function(){
var number:Number = Math.floor(Math.random()*5);
    for(i=0;i<number;i++){
    
    _root.attachMovie("spot","bubble"+i,i,{x:_root._xmouse,_y:_root._ymouse});
    _root["bubble"+i].tween("_y",0,1);
    }
    
}

```

it kind of works … but there’s a lot of canceling out too.  
Any Help or ideas?!  
Thanks 🙂
