Flash as3.0 can load external resources (images, MP3, SwF) in two ways

For external resources such as image loading in as3, I usually use two methods: loader and embed. Their respective features are summarized as follows: Embed: resources are embedded in the Flash compilation phase, that is to say, image resources will be compiled into SWF files. The advantage of this is that CodeIt is concise, easy to use, and there is no loading order problem. The disadvantage is that it increases the volume of SWF files. Loader: resources are dynamically loaded during the flash running stage. This method does not affect the volume of SWF files, in addition, you can flexibly change the resources you want to load, but you may encounter path changes or cross-domain problems. At the same time, excessive use of loader for dynamic loading will undoubtedly increase the burden on the server, therefore, we need to use the following example to weigh against embed: Embed: [embed (Source = ".. /assets/images/closebtn.png ")] private var closebtnimage: Class // image object to be embedded private var btnsprite: SPRITE = new sprite (); Private function test (): void {var BMP: bitmap = new closebtnimage (); btnsprite. addchild (BMP);} Loader: Private function additem (): void {var Loader: loader = new loader (); loader. load (New URLRequest ("http://zhufei.de/something.png"); loader. contentloaderinfo. addeventlistener (event. complete, loadcomplete);} // listens to the private function loadcomplete (E: Event): void {var L: loader+loader(e.tar get. loader); // obtain the loader object var BM: bitmap = Bitmap (L. content); // trace (l); trace (BM );}
