GammaGames / procedural-generation-ruleset

The goal of this project is to make an easy to write format for multi-dimensional and multi-pass procedural terrain generation. The format is easy to write and modify and flexible to use in use cases other than terrain generation. The above image was generated with the following config:

steps:
- height*moisture:
  # Base terrain
  - 1@2:rock,1:snow
  - 1@2:grass,3:plants
  - 2@1:sand,2:dirt,2:grass,3:plants
  - 1@2:sand,1:dirt,1:grass,1:plants,2:=water
  - 3@1:=water
  - tile*population:
    # Adding cities
    - sand@9:-,1:buildings
    - grass@2:-,1:buildings
    - dirt,plants@3:-,1:buildings

A full writeup on the format can be found on my personal blog or Medium, I have a little page hosted here, and you can download a playable demo in the releases.
