The 24 column, 18 row grid has a blue arrow on it that can move one block at a time. If the arrow moves off the screen, it will reappear on the other side of the screen. Coding that shows how to get grid movement working. You could use this for games based on a grid, like checkers, connect-4, battleship, chess, etc.
Just wanted to see how hard it would be to create grid based movement in a language like Scratch, where smooth, 360 degree movement is the norm.
