stopping from clicking over a spot

[JonnyBigBoi]

k, in my game i click to place my ovals on the grid, and i can still click on the squares that are occupied, how would i make it so the spaces stay the same and not change when you click on them.

code:

loop turnCounter += 1 %mouse stuff. %determine the value for x and y based on the width/height of each grid space and the offset (you probably won't have your grid start at (0,0). if grid (x, y) = -1 then % -1 represents empty, in this case   grid (x,y) := turnCounter mod 2 end if end loop
