This is a remix of Mouse in Maze (#4894). In order to help mouse get to cheese faster, we used the left hand rule. Couple events to handle: 1. make left whisker red for contacting wall, right whisker green for detecting wall collision. 2. first thing is to make left whisker contacting wall 3. what to do when left whisker is no longer in contact with wall 4. how do we know mouse is hitting a wall and what to do Mouse has been re-centered to assist turning, which could also be handled by special turn function, namely re-positioning mouse after turning.
This is not my work. All credit to original creator stingyinch.
