Fire event from one object to notify end of frame

问题

I am relatively new to AS and want to know how I can notify that an object I imported has reached it's final frame. Basically I want to create a .fla with a class file maybe and import the .swf as a movieclip in an other fla and maybe have multiple instances of that imported movieclip. Now I would like to know how I can get notified that one instance of the imported movieclip has reached the final frame.

Thank you

You can fire event with dispatchEvent(new Event("eventname")). Write dispatchEvent on end of frame.

dispatchEvent(new Event(Event.COMPLETE));

and, listen for the event:

mc.addEventListener(Event.COMPLETE, endOfFrameHandler);
function endOfFrameHandler(e:Event):void 
{
    ...
}

You can use MovieClip' undocumented addFrameScript() method , like:

mc.addFrameScript( mc.totalFrames - 1 , lastFrameHandler);

function lastFrameHandler():void{
    //
    // mc.stop();
    //
}

With addFrameScript you don't need to put any code in .fla' frames/timeline!
