I don't know how else to explain it
Example:
You draw an area for a player XYZ. This area then gets the name XYZ and the permissions for visitors (visitors are visitors - no matter what area; that's why you don't need 1, 2 or 3 of them).
If you don't assign permissions to the area, then it's basically like the rest of the world for the players.
Then go to “Add player” in the menu and add player XYZ to this area and then select the owner permissions for him.
So everyone except him is a visitor to this area.
All permissions stored in the Permissions/Area folder can be selected when creating an area. Both for the area itself, or for players.
The areas created in the game are stored in a database in the world folder.
