Here's what I did, don't know if it's nuts though. To avoid loading the same png every time I made a singleton of the PhotoFrame class and return a copy of the origional png as a bitmap. It works, don't know the performace difference between using a new Loader vs creating cloned bitmaps each iteration. What is the suggested way to avoid loading the same asset multiple times? for (var i:int=0; i < 400; i++){ new Photo(photoXML, PhotoFrame.getInsta nce().frame) ; } public class PhotoFrame extends Sprite { private static var instance:PhotoFrame = null; private var _loader:Loader = null; public function PhotoFrame() { _loader = new Loader(); _loader.contentLoad erInfo.addEventL istener(Event. COMPLETE, onFrameLoaded) ; _loader.contentLoad erInfo.addEventL istener(IOErrorE vent.IO_ERROR, onLoadError) ; _loader.load( new URLRequest(" frame.png" ) ); } public static function getInstance( ):PhotoFrame{ if(instance == null) instance = new PhotoFrame() ; return instance as PhotoFrame; } public function get frame():Bitmap{ var image:Bitmap = Bitmap(_loader. content); return new Bitmap(image. bitmapData. clone()); } private function onLoadError( e:IOErrorEvent) :void{ trace(e.text) ; } private function onFrameLoaded( e:Event): void{ trace('loaded' ); } } public class Photo extends EventDispatcher { private var _frame:PhotoFrame; public function Photo(photoXML: XML, frame:PhotoFrame) { _frame = frame; addChild(_frame) ; //... } } ____________________________________________________________________________________ Never miss a thing.
