Cloaking

Allows admins to become invisible and appear as if they are not in-game at all.

Server Moderation and Tools

NOTE: The screenshot is for demonstration purposes only, there are no semi-transparent players/objects in this mod, as cloaked players are fully transparent.

What is cloaking?

In this instance, cloaking is a way to go invisible and become undetectable by most mods (unless they explicitly want to detect cloaked players, so they can still send chat messages to them).

Why is cloaking so hacky?

The aim of cloaking is to trick other mods into thinking the player is not in-game, and a lot of hacks are used to do this.

Help, it crashes

If it crashes, it is either caused by a mod not liking non-existent players running around, or by a bug in cloaking itself.

How do I use cloaking?

Cloaking adds a modding API and some chatcommands. All of the chatcommands require the "cloaking" privilege to execute, with the exception of /uncloak when used on yourself.

  • /cloak [victim]: Cloaks yourself, alternatively an unsuspecting victim.
  • /uncloak [victim]: Uncloaks yourself, or a victim.
  • /cloak_chat <message>: Sends <message> to all online players with the cloaking privilege.
    • You can disable cloaked chat by adding cloaking.enable_cloaked_chat = false to minetest.conf.
  • /shadow [victim]: Attaches you to a player. If victim is not specified, this command will detach you instead.
    • Requires both the "cloaking" and "teleport" privileges.
    • This command can only be used while cloaked.
    • You can disable this by adding cloaking.enable_shadow = false to minetest.conf.

How do I download cloaking?

You can either run git clone https://git.minetest.land/luk3yx/cloaking.git or download this mod from ContentDB.

How do I use the API?

Cloaking adds the following functions:

  • cloaking.cloak(player): Cloaks a player.
  • cloaking.uncloak(player): Uncloaks a player.
  • cloaking.get_cloaked_players(): Gets a list of cloaked player names.
  • cloaking.get_connected_names(): Gets a list of cloaked and uncloaked player names.
  • cloaking.is_cloaked(player): Checks if a player is cloaked.
  • cloaking.hide_player(player): Hides a player without cloaking them.
  • cloaking.unhide_player(player): Unhides a player previously hidden with cloaking.hide_player().
  • cloaking.chat: Cloaked chat API, this is nil if cloaked chat is disabled.
  • cloaking.chat.send(message): Sends a message to cloaked chat.
  • cloaking.chat.prefix: The text (-Cloaked-) that is prepended to cloaked chat messages before they are sent to players.

Any above functions requiring "player" as a parameter also accept a player name, provided the player is online.

It also adds the following functions that ignore cloaked players and can interact with them: cloaking.get_connected_players, cloaking.get_objects_inside_radius and cloaking.get_player_by_name.

If you have made chatcommand work with players that aren't in-game, you can add _allow_while_cloaked = true to the chatcommand definition. If you explicitly don't want your chatcommand working with cloaked players, you can add _disallow_while_cloaked = true to the definition. These modifications do not require that you add cloaking as a dependency, as when cloaking is not loaded this parameter is simply ignored.

Backported bugfixes

To ensure server stability, the cloaking mod backports the following bugfixes if it determines they are necessary for your server:

  • Blocking newlines in chat messages (MT < 5.0.1).
  • Prevent saying %2 in chat from crashing the server (MT == 5.1.0).
  • Prevent hacked clients from being able to access the inventories of other players (MT < 5.4.0). Note that this fix currently needs testing and does not work on MT 0.4.

If you do not want this for whatever reason (although I do not recommend it), you can disable these backports by adding cloaking.backport_bugfixes = false to your minetest.conf.
