Players without the `interact` + privilege can only travel and observe the world. + + * Advanced privileges allow bypassing certain aspects of the gameplay: + * `fast`: can use "fast mode" to move with maximum speed. + * `fly`: can use "fly mode" to move freely above the ground without falling. + * `noclip`: can use "noclip mode" to fly through solid nodes (e.g. walls). + * `teleport`: can use `/teleport` command to move to any point in the world. + * `creative`: can access creative inventory. + * `bring`: can teleport other players to oneself. + * `give`: can use `/give` and `/giveme` commands to give any item + in the game to oneself or others. + * `settime`: can use `/time` command to change current in-game time. + * `debug`: can enable wireframe rendering mode. + + * Security-related privileges: + * `privs`: can modify privileges of the players using `/grant[me]` and + `/revoke[me]` commands. + * `basic_privs`: can grant and revoke basic privileges as defined by + the `basic_privs` setting. + * `kick`: can kick other players from the server using `/kick` command. + * `ban`: can ban other players using `/ban` command. + * `password`: can use `/setpassword` and `/clearpassword` commands + to manage players' passwords. + * `protection_bypass`: can bypass node protection. Note that the engine does not act upon this privilege, + it is only an implementation suggestion for games. + + * Administrative privileges: + * `server`: can use `/fixlight`, `/deleteblocks` and `/deleteobjects` + commands. Can clear inventory of other players using `/clearinv` command. + * `rollback`: can use `/rollback_check` and `/rollback` commands. + +Related settings +---------------- + +Minetest includes the following settings to control behavior of privileges: + * `default_privs`: defines privileges granted to new players. + * `basic_privs`: defines privileges that can be granted/revoked by players having + the `basic_privs` privilege. This can be used, for example, to give + limited moderation powers to selected users. 'minetest' namespace reference ============================== |
