Incognito

Minetest mod that lets you become completely* invisible - even to server status.

Description

The issue with the available invisibility Minetest mods is they don't make you completely invisible. Like sure you can't be seen, but what if it was as if you weren't even there, you can be playing the game, but also avoiding all of the annoying players begging for you to give them mese/gold/diamonds all day long.

This mod does just that, when you join with the incognito privilage, you are immediately set to incognito mode and given the option to become incognito this session, if you select "no", you lose your incognito status, the join message shows and it's as if you just joined, if you select "yes", you enter incognito mode until you leave the game or run /incognito.

So... what does incognito do exactly?

A few things:

• Makes the player and player nametag invisible (without resetting player skin and nametag color)
• Makes you invincible (Just in case of any death message mod)
• Makes you invisible to server status (Your name will no longer show up in the server status client list (viewable at login or via /status))
• Supresses your ability to send public chat messages (Messages and messages sent with /me will be stopped, can't have you leaking the fact you're incognito ;)
• Makes you silent (No footstep noises!)
• Lets you know you're incognito (via a HUD)
• Shows you a warning HUD if there are players nearby (so you don't go placing blocks or anything and blow your cover)

That said, it's not all sunshine and rainbows, Clients are still sent your nametag and player position, so you'll show up in the minimap and .list_players if you're within nametag range, or if the client is using a 0.5.0-dev or above client.

Installing

This isn't going to be like any regular mod instalation, we're going to also have to modify a built-in mod to get it to work properly, don't worry, it's fairly simple ;)

1. Alright first up navigate to your minetest folder, then to the folder called builtin, then to game, the path should look something like this: .\minetest-0.4.16-win64\builtin\game
2. Now open misc.lua in a text editor
3. Navigate to the end of line 45, it should say core.register_on_joinplayer(function(player), if it doesn't, try scroll up and down to find that block of code
4. Press enter and add below that line: if not minetest.get_modpath("incognito") then
5. Navigate to the end of line 51 (should say end), press enter and type end
6. Now find line 55, it should say core.register_on_leaveplayer(function(player, timed_out), and navigate to the end of it, we're going to do a similar thing to that function.
7. You know the drill, press enter and add below that line: if not minetest.get_modpath("incognito") then
8. Now navigate to the end of line 64 (should say end), press enter and type end

By the end of all that, the code from and including line 45 to and including 65 should look like this:

core.register_on_joinplayer(function(player)
    if not minetest.get_modpath("incognito") then
    local player_name = player:get_player_name()
    player_list[player_name] = player
    if not minetest.is_singleplayer() then
        core.chat_send_all("*** " .. player_name .. " joined the game.")
    end
    end
end)

core.register_on_leaveplayer(function(player, timed_out)
    if not minetest.get_modpath("incognito") then
    local player_name = player:get_player_name()
    player_list[player_name] = nil
    local announcement = "*** " ..  player_name .. " left the game."
    if timed_out then
        announcement = announcement .. " (timed out)"
    end
    core.chat_send_all(announcement)
    end
end)

Of course now install the mod into the mods folder as normal, and you should be ready to rock and roll.

Settings

There are a couple of setting which might be of interest of course:

• On line 1 of init.lua you'll see a variable called INCOGNITOCOOLDOWN, now you can change that to modify how long (in seconds, set to 0 to disable) to cooldown for using /incognito is, since over use would make it really obvious.

• On line 3 of init.lua you'll find a variable called PLAYERRANGE, set this one to how many nodes as a radius you want to search for other players (if they are in the radius a warning HUD will pop up), the default is 100, and we wouldn't recomend setting it too high because you'll probably end up with a fair amount of load on your server.

Notes

• This mod is still a work-in-progress, expect functionality to change slightly, if you have any improvements, please feel free to creat an GitHub issue, create a Pull Request or comment on the Minetest Forums (forum.minetest.net)
