Roblox Rooms - How do the entities work?

Only have footage of A-60. Forgot to record A-200 and didnt bother to rejoin. A-60: Once you pass room 60, there's a chance that it will go into "hunt" mode every time you open a door. It starts at a-0, or the starting room, and will go straight toward you at an incredibly fast speed, which differs depending on how far you have progressed. As seen in the video, if everyone is hiding, it will just stand still and will despawn after a couple of seconds. It only moves when theres at least one person out of a locker. A-200: Once you pass room 200, there's a chance that it will go into "hunt" mode just like A-60. It starts a short distance ahead of you rather than behind. It moves pretty slow, but it's still a little bit faster than you are even when sprinting. Similar to A-60, it will only move toward you when you're not hiding, except whenever everyone is hidden, it actually moves away from you rather than just stopping. Once it's gotten far enough from you, it will despawn, playing a slow "whoosh" sound. Thanks for reading.
