Flash CS3 z-index, display index, etc…

If you’re a noob in Flash, looking for z-index in AS3. well, there isn’t one.
There used to be a property called depth. But now it has become an index of the array object.
So for example, you add a dynamic object into Flash MainTimeLine at runtime. your “z-index” is your index within the MainTimeLine’s object array.
To set the index. Use setChildIndex(childObject, i); where childObject is the object in question, i is an integer. This would add the child into that index and move the “original occupant” and everything above that up by 1.
