Create a wrapper class that extends MovieClip in your main app that will handle
the loading of the external swf's (into a sub
movieclip of the wrapper)
// pseudo code
import mx.utils.Delegate;
class SWFLoader extends MovieClip {
//
private var holder_mc:MovieClip;
private var loader_mcl:MovieClipLoader;
//
function SWFLoader() {
trace("SWFLoader ::: CONSTRUCTOR");
this.loader_mcl = new MovieClipLoader();
this.loader_mcl.addListener(this);
this.createEmptyMovieClip("holder_mc", this.getNextHighestDepth());
this.loader_mcl.loadClip("external.swf", this.holder_mc);
}
//
private function onLoadInit(_mc:MovieClip):Void {
trace("SWFLoader ::: onLoadInit");
// listen for "frameReached" event, dispatched by external swf
_mc.addEventListener("frameReached", Delegate.create(this,
this.frameReachedHandler));
}
//
private function frameReachedHandler(o:Object):Void {
trace("SWFLoader ::: frameReachedHandler");
trace(" - frame reached: "+o.frame);
// do something here depending on which frame has been reached
// or dispatch an event to listeners
}
}
// end pseudo code
Then in the external swf, decorate it with EventDispatcher.
// frame 1 - main timeline of external swf
import mx.events.EventDispatcher;
EventDispatcher.initialize(this);
// some other frame in external swf
// dispatch event to listener
this.dispatchEvent({type:"frameReached", frame:this.__currentframe});
It's quick and dirty, but gets the job done ;-)
Part from adding the EventDispatcher stuff in the animation swf's you don't
have to change them.
And in your main app you still get to work in a clean way, using a Class and
event dispatching.
