so I have a function programmed into the start of a movie

it’s

function ballMove(e:Event):void {  
var spin: Tween = new Tween (ball\_mc, “rotation”, Elastic.easeOut, 0, 360, 5, true);  
}

I tried using ball\_mc.addEventListener(Event.ENTER\_FRAME, ballMove) to start the function, and it wouldn’t work it would just jitter around on the screen

I solved it by calling the function directly using ballMove(); and getting rid of the e:Event from the function

can you not Tween automatically using the ENTER\_FRAME event?
