The following example displays the gpUrlLoader Class with an option to load a sound file. Add the event listener, then call the init method with the url and the load type.
I also added a progress and Load Error Listener. With the Progress Listener, you can track bytesLoaded and bytesTotal.
var ldr:gpUrlLoader = new gpUrlLoader();
ldr.addEventListener(Event.COMPLETE, soundLoaded);
ldr.addEventListener(ProgressEvent.PROGRESS, onProgress);
ldr.addEventListener(gpUrlLoader.LOADERROR, ioError);
ldr.init('StarGate-SG1-mp3', 'sound');
function soundLoaded(event:Event):void {
var snd:Sound = ldr.getSound();
}
function onProgress(event:Event):void {
trace(ldr.urlLoader.bytesLoaded);
}
function ioError(e:Event):void {
trace('Error loading file');
}
