How to determine whether AVM1Movie is finished? - actionscript-3

Question

I'm using Loader to add AMV1Movie (movie created using Toon Boom Studio) to my AS3.0 stage. How can I determine when AMV1Movie plays it's last frame?

Answer 1

Without dispatching something from the original movie, you'd have to poll it's currentFrame and numFrames properties, and that will only be accurate if the main timeline is an accurate depiction of the animation/program. If the AVM1Movie animates via code or has nested movieclips, there's no good way to know when it is "finished".
The best bet is to open it up and add an event to the end.

Answer 2

I use ForcibleLoader to load AVM1Movie as MovieClip:
var uic: UIComponent = ....
...
var loader:Loader = Loader(1uic.addChild(new Loader()));
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, startPlay);
var fLoader:ForcibleLoader = new ForcibleLoader(loader);
fLoader.load(new URLRequest("....swf"));
then I check if (movie.currentFrame + 1 >= movie.totalFrames)
I use this function to control uic.click event to stop and play movie:
private function controlSwf(event: Event): void {
var e: Event = event;
var movie: MovieClip = MovieClip(Loader(event.target).content);
if (movie.currentFrame + 1 >= movie.totalFrames) {
movie.gotoAndPlay(1);
play = true;
} else if (play) {
play = false;
movie.stop();
} else {
play = true;
movie.play();
}
}
