Basically /title kinda like how we have InZone, something opposite to that, where if there's no one in the zone it can trigger an event.
Example
OnZoneEmpty - NamedBrick[Bot] - SetBotType - None
So if there's no one in the zone a bot wouldn't spawn, and that's just an example I wouldn't use it for that but for something else. I would appreciate it a lot thanks in advance.
