Как узнать width и height клипа (MovieClip)

[Visual]

Кусок из основного класса:

var map:GameLoader = new GameLoader("map.swf", 300, 300);
addChild(map);

Вот класс Лоадера:

package main{

	import flash.display.Sprite;
	import flash.display.Loader;
	import flash.display.LoaderInfo;
	import flash.text.TextField;
	import flash.text.TextFieldAutoSize;
	import flash.net.URLRequest;
	import flash.events.Event;
	import flash.events.ProgressEvent;
	import flash.net.LocalConnection;
	import flash.display.MovieClip;

	public class GameLoader extends Sprite {
		public var loader:Loader = new Loader();
		private var loadStatus:TextField = new TextField();
		private var preloader_mc:Preloader = new Preloader();
		private var posX:int = 0;
		private var posY:int = 0;

		public function GameLoader(movie:String, x:int=0, y:int=0) {
			var request:URLRequest = new URLRequest(movie);
			posX = x;
			posY = y;
			loader.load(request);
			loader.contentLoaderInfo.addEventListener(Event.OPEN,displayPreloader);
			loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS,updatePreloader);
			loader.contentLoaderInfo.addEventListener(Event.COMPLETE,displayMovie);
		}

		private function displayPreloader(evt:Event):void {

			this.addChild(preloader_mc);
			preloader_mc.x = 200;
			preloader_mc.y = 200;

		}
		private function updatePreloader(evt:ProgressEvent):void {

			var bytesLoaded:Number = evt.bytesLoaded;
			var bytesTotal:Number = evt.bytesTotal;
			var s:String = "";
			var percent:Number = 0;
			if (bytesTotal>0) {
				percent = Math.floor(bytesLoaded/bytesTotal*100);
			}
			preloader_mc.txt.text=percent+"%";
			preloader_mc.progressbar.gotoAndStop(percent+1);

		}
		private function displayMovie(evt:Event):void {

			removeChild(preloader_mc);

			var movie:MovieClip = evt.target.loader.content.movie;
			this.addChild(movie);
			movie.x = movie.width/2;
			movie.y = movie.height/2;
			movie.play();
			trace(movie.width);
			trace(movie.height);

			loader.contentLoaderInfo.removeEventListener(Event.OPEN,displayPreloader);
			loader.contentLoaderInfo.removeEventListener(ProgressEvent.PROGRESS,updatePreloader);
			loader.contentLoaderInfo.removeEventListener(Event.COMPLETE,displayMovie);

		}
	}
