If you mouse click on a corner that half of the square will turn black. But it won't stay black. Trying to make a tool to design quilt pattern blocks. Thisis just a test square for a Scratch project that would have 12 squares. Need help programming it to stay black when corner clicked if clicked again turn white. Is that a variable?
What can I add to the script to make the black half stay? If click again turn white.
