Question

OK, I took suggestion given in comments and trying to convert this flash game to AS3.

The class looked like this before I converted it

package  
{
    import flash.events.EventDispatcher;
    import flash.display.MovieClip;
    public class eventsBroadcaster extends MovieClip
    {
        public var addEventListener:Function;
        public var removeEventListener:Function;
        public var dispatchEvent:Function;

        public function eventBroadcaster() 
        {
            EventDispatcher.initialize(this);
        }
    }
}

But then I had to get rid of all three :Functions as errors said they are conflicting. Looks like in the new flash.events.EventDispatcher, they are already there. The only error I get now is

1061: Call to a possibly undefined method initialize through a reference with static type Class.

If curious, original question was:
Trying simple flash game in AS2. New to flash development. I keep getting this error and my flash game pops up empty.

Answer 1

I occassionally see similar errors when my class functions need to be made explicitly public, which was a common coding style in AS2.
