I wrote a maze solving program in Logo which determines whether a sprite is near a wall by modifying various bits in the sprite's bitmap and checking to see if it had "collided" with one of the walls. The question is, how are collisions detected? Is it done during refresh, meaning I should wait for a full refresh to occur before checking the collision bit? Anyone know of a cute Logo statement that will wait that long, or can I check the progress of the refreshing as it goes on? Many thanks! -Neal McBurnett, ihnp4!druxv!neal
