I see in zonemanager u can have 3 custom commands
Can i enable it so one of them turns off noclip if the player has it on when they enter that zone ??

The "noclip" from Rust is a client setting, not something the server can toggle.

Fauxadmin manages it with the toolcupboard range
Fly into someone elses cupboard range and fly mode is turned off and you drop to the floor and thats a plugin.
Or maybe its not actually turning the flymode off - its just dropping them which is fine
How can i do that in Zonemanager ??
