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 calculations - `noise`, 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.
