priv_protector for minetest

Adds a protection block that checks the priv of the builder/digger

Usage

Define a few global privs that you want to give out to trusted builders:

minetest.register_privilege("protect_streets", {
	description = "Protection for common streets"
})

Place the priv_protector block and change the "Privilege" field to protect_streets or whatever you want to protect with

Additional area mod commands:

area_priv_set Sets a privilege for the area (the area needs to be opened with /area_open <id> for this to work)
area_priv_get Returns the privilege, if any, required for that area
