Is it possible to arrange (z) order of objects in Flash with ActionScript 3?
e.g. I have 3 symbol instances on a given layer, and I want to perform the equivalent of 'Bring to Front', 'Bring Forward', and/or target a certain z position.
You can change the z-index (stacking order) of a movie clip within a same layer using action script like this.
parent.setChildIndex(childObject, i)
Change childObject to the name of the movie clip you want to change the z-index, change i to an integer (the desired z-index value).
If you want to make this happen on a mouse event, put above code inside a function and attach an event listener to a button to invoke this function on a mouse event.
