mapgen_rivers
Procedural map generator for Minetest 5.x. Still experimental and basic.
Contains two distinct programs: Python scripts for pre-processing, and Lua scripts to generate the map on Minetest.
Installation
This mod should be placed in the /mods directory like any other Minetest mod.
The Python part relies on external libraries that you need to install:
numpy, a widely used library for numerical calculationsnoise, doing Perlin/Simplex noises- optionally,
matplotlib(for map preview)
They are commonly found on pip or conda Python distributions.
Usage
Pre-processing
Run the script terrain_rivers.py via command line. You can optionally append the map size (by default 400). Example for a 1000x1000 map:
./terrain_rivers.py 1000
For a default 400x400 map, it should take between 1 and 2 minutes. It will generate 5 files directly in the mod folder, containing the map data (1.4 MB for the default size).
Map generation
Just create a Minetest world with singlenode mapgen, enable this mod and start the world. The data files are immediately copied in the world folder so you can re-generate them afterwards, it won't affect the old worlds.
