I use codes like this to load movie clips into a loader.
However, i cannot figure out how to create a preloader that will show its
progress, since most BAR tutorials are for AC2.

Can someone tell me how to do this with AC3?

Thank you.

function toCLR(e:MouseEvent):void {
view14.removeChild(externalMovie);
var request:URLRequest = new URLRequest("media/CLOFT.swf");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(flash.events.Event.COMPLETE,
Tier2A);
loader.load(request);
function Tier2A(e:Event) {
externalMovie = MovieClip(loader.content);
view14.addChild(externalMovie);
view14.addChild(loader);
}
}
