I'm afraid that doesn't seem to work for me... Here's my aprox. event:
On object A clicked -> Object B do something.
Both object A and B are on layer 0 and on layer 1 and even if I add the is layer visible condition, both object Bs do something - the one on layer 0 and the one on layer 1.
Maybe I should change topic title to layers instead of objects but I don't know hot to do that.
