Hi, I have 3 copies of this boxMC which are intended to bounce around inside a \_root mc.

Each has a different instance name so when I do a

trace(this);

I get:

\_level0.box1  
\_level0.box2  
\_level0.box3

as each of my 3 boxes tells me what their names are.

I want to do a For statement with this kinda thing in it:

if (this == \_level0.box\*)

but it doesn’t work, hope someone knows what I mean and can help me out? I’ll attach a .fla (mx2004) to look at. Also, any tips on how to get these boxes bouncing around inside a perimeter?

Cheers  
Pete
