Thanks for the help guys, but this still doesn't work as intented.
Maybe I wasn't clear enough but I need to use only one object besides the player. There's no point on having duplicates of duplicates.
I tried using variables now but I don't know if to use instance variables or global variables. Or how to select a specific door (because the action should be triggered with Any door or I'll turn more crazy) Any help appreciated.
@mepis, can you elaborate your example? Also I don't mind having to choose like that, but my game will have like 10-15 doors, so it might be annoying to type, say "choose(1, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)" for each door (deleting and adding one number, obviously)... but if there's no other way, then no probs =P
Made a new mockup to make this idea more "readable". The only objects here are "player" and "doors". Of course each door has a specific UID (created all of them with Ctrl+Click except the first one)
