What is a Map?
A Map is a world who contains an environment and/or building(s).
Installation
To install maps : you have to extract them first—most of them are in .zip
, some of them can be in .rar
or .tar.gz
format. To extract .tar.gz
and .rar
files on Windows, you need 7-Zip.
Put the extracted files in the “worlds
” folder of your Minetest installation folder. The files such as env_meta.txt
must be directly in the world’s folder (eg. “worlds/my_world/env_meta.txt
”).
Often, the compressed file also contains a “mods
” folder, his files have to be put into your “mods
” folder to show some additional blocks.
- Location of the
worlds
(aka maps) folder within the folder structure of a run-in-place installation of Minetest, including some of the folders Minetest adds after some usage as client and server, as well as the positions (…) that custom-made content goes. Irrelevant folders are not expanded.
This commented example shows the location and structure of a world called "someworld": minetest/ ├── bin/ (contains the executable program file) ├── builtin/ ├── cache/ ├── client/ ├── doc/ ├── fonts/ ├── games/ (collection of mods tweacked or designed to work well together) │ ├── minetest_game/ │ ├── minimal/ │ └── … (installed extra games) ├── locale/ (language files) ├── mods/ │ └── … (installed extra mods and modpacks) ├── textures/ │ ├── base/ │ │ └── pack/ │ └── … (installed extra texturepacks) │ ├── worlds/ (this folder will be created when the first local/singleplayer world is created) │ ├── someworld (the name given to the world by the user when it is created) │ │ ├── players/ (ingame data for each player) │ │ ├── worldmods/ (create this folder for world exclusive mods) │ │ ├── auth.txt (player login data) │ │ ├── env_meta.txt (contains mostly time related information) │ │ ├── map.sqlite (database containing the map. The name may differ depending on backend used) │ │ ├── map_meta.txt (defines which mapgen is used and how) │ │ └── world.mt (should at least contain the subgame-id without which the world │ │ will not show up in the singleplayer tab) │ └── … (more saved worlds. Some with exclusive world mods) │ ├── minetest.conf (will be created with first start of Minetest) └── minetest.conf.example (a list of all possible settings)
World Folder Content
as described in the file world_format.txt shipped with each Minetest in the docs folder.
auth.txt
Contains authentication data, player per line.
<name>:<password hash>:<privilege1,...>
Legacy format (until 0.4.12) of password hash is <name><password> SHA1'd, in the base64 encoding.
Format (since 0.4.13) of password hash is #1#<salt>#<verifier>, with the parts inside <> encoded in the base64 encoding. <verifier> is an RFC 2945 compatible SRP verifier, of the given salt, password, and the player's name lowercased, using the 2048-bit group specified in RFC 5054 and the SHA-256 hash function.
env_meta.txt
Simple global environment variables. Example content:
game_time = 73471 time_of_day = 19118 EnvArgsEnd
ipban.txt
Banned IP addresses and usernames. Example content:
123.456.78.9|foo 123.456.78.10|bar
map_meta.txt
Simple global map variables. The map generator may be defined here and tweaked with parameters. Example content:
seed = 7980462765762429666 [end_of_params]
map.sqlite
Map data. Name may differ according to the database backend type used.
world.mt
World metadata. At least this file should be present together with a database file as minetest will not list the world if it does not know which subgame is needed for the map. Example content:
gameid = mesetint
/player (folder)
Player data. Filename can be anything. Contains ingame data for each player in a file named after the player.
/worldmods (folder)
This optional folder may contain mods that are needed for this map exclusivly.
Finding Maps
Schem file Creation / Import
A schem file (.mts
) is used to import building(s) into a world with the WorldEdit mod. This file can be found in “worlds/<my_world>/schems
” folder.
- To create a schem file :
- Type in your world name (with WorldEdit activated).
- Grant yourself all privileges:
/grantme all
- Press F5 to show the coordinates.
- Select the area to export by commands with
//pos1
and//pos2
(these positions corresponds to an invisible diagonal of a cuboid selection). - Create your schem file with
//mtschemcreate <name of your schem file>
. The file will be created into your “worlds/<my_world>/schems
” folder.
- To import a schem file :
- Enter in your world (with WorldEdit activated).
- Grant yourself all privileges:
/grantme all
- Put a schem file into your “
worlds/<name of your new world>/schems
" folder. - Press F5 to show the coordinatess.
- Place a position where you want with command:
//pos1
- Import your schem file with
//mtschemplace <name of your schem file>
