# MinedMap
|
|
|
|
* Render beautiful maps of your [Minecraft](https://minecraft.net/) worlds!
|
|
* Put them on a webserver and view them in your browser!
|
|
* Compatible with unmodified Minecraft Java Edition 1.8 up to 1.20 (no mod installation necessary!)
|
|
* Illumination layer: the world at night
|
|
* Fast: create a full map for a huge 3GB savegame in less than 5 minutes in single-threaded operation
|
|
* Multi-threading support: pass `-j N` to the renderer to use `N` parallel threads for generation
|
|
* Incremental updates: only recreate map tiles for regions that have changed
|
|
* Typically uses less than 100MB of RAM in single-threaded operation (may be higher when `-j` is passed)
|
|
* Cross-platform: runs on Linux, Windows, and likely other systems like MacOS as well

## About
|
|
|
|
MinedMap consists of two components: a map renderer generating map tiles from
|
|
Minecraft save games, and a viewer for displaying and navigating maps in a browser
|
|
based on [Leaflet](https://leafletjs.com/). The map renderer is heavily inspired by
|
|
[MapRend](https://github.com/YSelfTool/MapRend), but has been reimplemented from scratch
|
|
(first in C++, now in Rust) for highest performance.
|
|
|
|
## How to use
|
|
|
|
Minecraft stores its save data in a directory `~/.minecraft/saves` on Linux,
|
|
and `C:\Users\<username>\AppData\Roaming\.minecraft\saves`. To generate MinedMap
|
|
tile data from a save game called "World", use the a command like the following
|
|
(replacing the first argument with the path to your save data; `viewer` refers
|
|
to the directory where you unpacked the MinedMap viewer):
|
|
```shell
|
|
minedmap ~/.minecraft/saves/World viewer/data
|
|
```
|
|
|
|
The first map generation might take a while for big worlds, but subsequent calls will
|
|
only rebuild tiles for region files that have changed, rarely taking more than a second
|
|
or two. This makes it feasible to update the map very frequently, e.g. by running
|
|
MinedMap as a Cron job every minute.
|
|
|
|
Note that it is not possible to open the viewer *index.html* without a webserver, as
|
|
it cannot load the generated map information from `file://` URIs. For testing purposes,
|
|
you can use a minimal HTTP server, e.g. if you have Python installed just run the
|
|
following in the viewer directory:
|
|
```shell
|
|
python3 -m http.server
|
|
```
|
|
This test server is very slow and cannot handle multiple requests concurrently, so use
|
|
a proper webserver like [nginx](https://nginx.org/) or upload the viewer together with
|
|
the generated map files to public webspace to make the map available to others.
|
|
|
|
### Signs
|
|
|
|
|
|
|
|
MinedMap can display sign markers on the map, which will open a popup showing
|
|
the sign text when clicked.
|
|
|
|
Generation of the sign layer is disabled by default. It can be enabled by passing
|
|
the `--sign-prefix` or `--sign-filter` options to MinedMap. The options allow
|
|
to configure which signs should be displayed, and they can be passed multiple
|
|
times to show every sign that matches at least one prefix or filter.
|
|
|
|
`--sign-prefix` will make all signs visible the text of which starts with the
|
|
given prefix, so something like `--sign-prefix '[Map]'` would allow to put up
|
|
signs that start with "\[Map\]" in Minecraft to add markers to the map. An
|
|
empty prefix (`--sign-prefix ''`) can be used to make *all* signs visible on
|
|
the map.
|
|
|
|
`--sign-filter` can be used for more advanced filters based on regular expressions.
|
|
`--sign-filter '\[Map\]'` would show all signs that contain "\[Map\]"
|
|
anywhere in their text, and `--sign-filter '.'` makes all non-empty signs (signs
|
|
containing at least one character) visible. See the documentation of the
|
|
[regex crate](https://docs.rs/regex) for more information on the supported syntax.
|
|
|
|
All prefixes and filters are applied to the front and back text separately, but
|
|
both the front and the back text will be shown in the popup when one of them
|
|
matches.
|
|
|
|
## Installation
|
|
|
|
Binary builds of the map generator for Linux and Windows, as well as an archive
|
|
containing the viewer can be found on the GitHub release page.
|
|
|
|
Building the generator from source requires a recent Rust toolchain (1.72.0
|
|
or newer). The following command can be used to build the current development version:
|
|
```shell
|
|
cargo install --git 'https://github.com/neocturne/MinedMap.git'
|
|
```
|
|
|
|
In addition, CMake is needed to build the zlib-ng library. If you do not have
|
|
CMake installed, you can disable the zlib-ng feature by passing `--no-default-features`
|
|
to cargo. A pure-Rust zlib implementation will be used, which is more portable,
|
|
but slower than zlib-ng.
|
|
|
|
If you are looking for the older C++ implementation of the MinedMap tile renderer,
|
|
see the [v1.19.1](https://github.com/neocturne/MinedMap/tree/v1.19.1) tag.
