basically, i am making game similar like air hockey .
My game will support two players. Now I want to prevent player 1's motion in to player 2's region and vice versa.
Half area of board is respective player's region.
player 1 should not move into player 2's region..
for moving striker I am using Drag and drop behavior.
Touch behavior is not working well.
how can i prevent player 1 to player 2's region.
