rooms & doors reference!!!! B-100's Speed: Very a183 B-100 will start at B-000, speeding to the latest room. When it has reached the latest room, it will stay in the middle and break half of the grey lockers but none of the blue lockers of the latest room for a bit. Do not get out of your hiding spot because it will instantly kill you. After a few seconds, it will speed back to B-000 break the B-001 door and then it will despawn.
code by @loosh24Ge I edited it to be more like the B-100 I made
