I am trying to setup my game so that when one user selects a mode/button, the other user cannot select that mode/button, and have to choose the other button. I am using bluetooth connection, and it almost works, but no matter what the user chooses, it just hides my attack button. I have two buttons, attackButton and hungerButton. (I have the GameKit Framework included.) PLEASE HELP ME!
