Hi Guys,

Ok so i have a class called Level that has an instance of a class called Resource.

The Level class uses the Resource class to load in a resource. So Resource.load(picture).

I want the Level class to know that the picture has been loaded so that it can add it to the stage.

Any idea how I can broadcast an event across my classes?

Thanks!
