How can I disable an actor from being used again after its been used once?
Im making a jeopardy iPhone game for myself so I can study for exams. It is going well except is there any way that I can get something to not get pressed again after I've pressed it? Like say I've pressed x category for 100. I would then answer the question and go back to the screen with the categories and values. So how would I make it so that 100 that i pressed and answered can't be pressed again?
