AS3 - numChildren level?

2008-08-12

Dear Flashers,

I'm not desperate in need of a solution, but enlightenment is needed.

I'm colorizing a grayscale image with a Sprite and a Blend.OVERLAY.
Which works fine. Since the Sprite is on top and the Bitmap below - i'm using addChildAt().

The problem arises when i want to check if there's Sprite/Bitmap at a level already. The numChildren returns the amount of children in the object but i cannot find a way to do the same on different levels?

Can I check the names of the objects added or is there a sweeter solution?

Thanks in advance,
Tor

If I am correct each level can only have one DisplayObject. If you wanted to know what DisplayObject is at a certain level you could:

getChildAt(index:int)

isplayObject
Returns the child display object instance that exists at the specified index.

getChildIndex(child

isplayObject):int
Returns the index position of a child DisplayObject instance.

Not sure if you just need to check if there is a DisplayObject at that level or if you need the name or index.
