Hi, You can indeed use attachMovie or you can wait for the movieClip.onLoad.

mc2.onLoad = Delegate.create(this, onInitClass);

Now you can call your methods of MovieClass2.

When you call mc1.mc2.customMethod() directly from the stage you don’t have to wait for the onload.

Using “childObject.onLoad” in the parent constructor seems to work well for me on this. I then make a function that deals with all the things I want to tell the child to do. The only issue I have had with this is that the child renders one frame as a movie clip before all its methods are called, so I often need to turn off then on the alpha.

Two more possible solutions:

- Have the child MC “report” to its parent in its constructor that it’s ready. This assumes that the parent will have a pre-determined function name (something like childReady()).

- Use attachMovie() to create the child MC dynamically; in this situation, the child class seems to be ready right away.

I really have to get on the AS3 boat, because I cry a little inside every time I have to make my classes interdependent to avoid a Flash quirk.

I ended up changing my code so that I didn’t need to call methods on the child clip. That probably doesn’t help you much Colin Moock uses setInterval() to continually check the child clip until the method appears, but I find that inelegant.
