For your information: Even though the manual doesn't mention this explicitly, GameMaker can process more than 5 touch points. I've tested this up to 10 on the UWP and HTML5 targets. You may ignore the rest of this thread. In my free time I help develop prototypes for a board game company that experiments with touch tables. The monitors they use in their tables can register up to 12 touch points. For some games where more than 6 players sit around the table the 5 touch points in GMS put a limit on simultaneous gameplay. Is there any chance that you increase the number of touch points that GMS can register to 10?
