I'm thinking of creating a mobile game for Android/iOS. Is it possible for GameMaker to recognize specific hand gestures on a touchpad? Like, draw a circle to attack; draw a square to defend (regardless of the size)? Sidenote: Or even better, a larger circle deals higher damage, but takes longer to cast. (assuming, size recognition is a possibility) Or is it only limited to 'tap to attack' and 'hold to defend'?
