Thanks Tracy, Nate! Ok, that worked, in that it got rid of the errors. But then I got a type conversion error about not being able to convert a Sprite to a UIComponent. So I read throught some blogs and found this rawchildren solution and using Shape too. So now I get a circle on the screen with no errors but the evenhandlers dont seem to be working.
Here is what I have (below). I think I'm going to have to use a timer. I dont think that .ENTERRAME is going to work in Flex is it? Here is a nice example. I might take this route instead. http://www.fortegames.com/games/CannonBall/CannonBallTest.html brad code follows........ *********************************************************** <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute" creationComplete="buildCircle()"> <mx:Script> <![CDATA[ import flash.display.*; import flash.events.Event; import flash.events.MouseEvent; public var circle:Shape = new Shape(); private function buildCircle():void{ circle.graphics.beginFill(0x990000); circle.graphics.drawCircle(50, 50, 50); circle.graphics.endFill(); circle.addEventListener(MouseEvent.CLICK, startAnimation); this.rawChildren.addChild(circle); } private function fadeCircle(event:Event):void{ circle.alpha -= .05; if (circle.alpha <= 0) { circle.removeEventListener(Event.ENTER_FRAME, fadeCircle); } } private function startAnimation(event:MouseEvent):void{ circle.addEventListener(Event.ENTER_FRAME, fadeCircle); } > </mx:Script> </mx:Application> --- In [email protected], Nate Beck <n...@...> wrote: > > Tracy beat me to it... but I'm going to send my email as well :). > This is because your code isn't in an event handler.
