The user starts at location (1, 2). Directly across the room from the user is a door. The door may be blocked by 0, 1, or 2 force fields. The frame of the door identifies which force field is currently blocking it: a red frame means that only the red force field is on, a yellow frame means that only the yellow force field is on, an orange frame means that both force fields are on, and a green frame means that both fields are off.
Depending where the user steps in the room one of the force fields will either turn on or off. The goal of the puzzle is to cross the room (i.e., reach position (1,0)) facing the door with both force fields off (i.e., a green frame).
This class allows a user to walk around in a virtual 3x3 room and solve a puzzle.
