How to change attribute when touching another actor?
Sorry if this question has already been posted, but i couldn't find the answer i'm looking for.
I'm making a game and i want to change the attribute of an actor +1 or -1 when touching the corresponding actors (+ button, - button).
I know how to hide it when it reach 0, but i want it to stop at 4.
Help me with the rules please, i'm a beginner with gamesalad.
