Minetestmapper

The Minetestmapper creates 2D maps of your world, where one node corresponds one pixel.

Usage

This describes the usage of the C++ minetestmapper. The usage of minetestmapper.py is similar.

Make sure there is a colors.txt in the same folder as the mapper. You might want to download VanessaE’s more complete colors.txt

On Linux open a terminal in the folder the mapper is. Create a map using this command.

./minetest_mapper -i /home/user/.minetest/worlds/my_world/ -o /home/user/map.png

Having minetest running in place you might have to modify the world path.

On Windows press shift and right click in the folder the mapper is in, select the command prompt. To create a map type this command.

minetest_mapper.exe -i "C:\your_path_to_minetest\Minetest\worlds\example\" -o map.png

The geometry option allows you to define an area to map. Use it between “./minetestmapper” and the input “-i”.

--geometry -10000:-10000+20000+20000

Result: A 20.2 MiB file covering a 20,000 × 20,000 area starting in the lower left corner at X=-10,000; Y=-10,000

Versions

Currently there are two mappers. It is recommended to use the C++ version.

minetestmapper.py

A mapper written in Python. It comes with Minetest and can be found in ./minetest/util/

minetestmapper in C++

The minetestmapper rewritten with C++. It is much faster. The code can be found on GitHub.

minetestmapper-numpy.py

An improved version of the python mapper with many additional features, as sideview, scaling and fog. It is 8 to 10 times faster than the original minetestmapper.py, but still slower than the c++ code. Information about installation and usage can be found in the forum.
