Preloading in AS3

April 27, 2008 · Posted in AS3, Flash · Comment

The process of preloading in AS3 is quite different to AS2. In my AS2 projects I often use a small (<20K) loading progress indicator to preload the larger application SWF. Once the main SWF is completely loaded, I would then replace the preloader content with that of the application.

One easy alternative to this is to add the loaded application content directly to the stage instance of the preloader.

My preloader code:

package  {
    import flash.display.DisplayObject;
    import flash.display.Loader;
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.ProgressEvent;
    import flash.net.URLRequest;

    /**
    * ...
    * @author Zu
    */
    public class Preloader extends Sprite {
        private var loader:Loader;

        public function Preloader() {
            loader = new Loader();
            loader.contentLoaderInfo.addEventListener( Event.INIT, onLoadInit );
            loader.contentLoaderInfo.addEventListener( ProgressEvent.PROGRESS, onLoadProgress );
            //The name of the application file to be loaded is passed in through flashvars or query string.
            //Assuming that I've named my flashvar as FILE
            var sAppFile:String = loaderInfo.parameters["FILE"];
            loader.load( new URLRequest(sAppFile));
        }

        private function onLoadProgress(e:ProgressEvent):void {
            //simple trace to see the loading progress.
            //code some sort of visual indicator of progress
            trace( e.bytesLoaded );
        }

        private function onLoadInit(e:Event):void {
            //add the loaded application to the stage
            stage.addChild(loader);
	    //remove the preloader
	    this.parent.removeChild(this);
        }

    }

}

This can easily be modified to preload multiple files.
