How would a server owner find out the areas protected by F9?
The permissions.json has the "true" or "false" items listed to make things available or not. Here is an example of permissions one can have in their protected area...
"general": {
"changeblockshape": true,
"changeclothes": true,
"changegamemode": false,
"changeskin": true,
"crafting": true,
"destroyitems": true,
"destroyownvehicles": true,
"destroyvehicles": false,
"dropitems": true,
"edititems": true,
"editnpcs": false,
"editownitems": true,
"editownvehicles": true,
"editvehicles": true,
"fixedspawn": false,
"fly": false,
"godmode": false,
"healthregeneration": 0.5,
"instantdigging": false,
"keepinventory": true,
"noclipping": false,
"nofalldamage": false,
"nohungerthirst": false,
"nostamina": false,
"notemperature": false,
"openinventory": true,
"pickupitems": true,
"placeitems": true,
"placevehicles": true,
"pve": true,
"pvp": false,
So the above snippet shows what a player can or can not do while in the area. You can modify the "default" permission and save them as .json file (not txt) like "owner", "guest", etc. each permission modified to the players permission to do in that protected area. When you assign the owner of the property, set permission to owner and then the players name of that area. Player must be online at time of property protection assignment.
