I've made this code that successfully creates a 16x12 grid by 50x50 squares on a 800x600px board.
As you can see, the player moves to the coordinates of the players mouseclick.
Each square of the grid has an object of Felt (field) on it, which can be laast (locked). If a fields lock attribute is set to 1, the player should not be moved to that position.
How do i detect the field a player tries to move on to achieve this?
