Re: [flexcoders] var circle:Sprite = new Sprite(); Not working

[Nate Beck]

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.  In MXML you can't have
"free-floating" script, just like in an ActionScript 3 class, you can't have
circle.graphics.beginFill(0x990000) outside of a method.
I recommend doing the following:

Change your mx:Application tag to read as this:
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"
creationComplete="onReady()">

Then:

<mx:Script>
<![CDATA[
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;

private function onReady():void {
var circle:Sprite = new Sprite();
circle.graphics.beginFill(0x990000);
circle.graphics.drawCircle(50, 50, 50);
circle.graphics.endFill();
addChild(circle);
}

]]>
</mx:Script>
