Worldgen

Worldgen allows you to generate random worlds.

Installation

Add this line to your application's Gemfile:

gem 'worldgen'

And then execute:

$ bundle

Or install it yourself as:

$ gem install worldgen

Usage

So far there is not much. You can do square heightmaps:

# Create a 50x50 heightmap - this will be flat
heightmap = Worldgen::HeightMap.new 50

Then you can do a diamond square fractal to it:

Worldgen::Algorithms.diamond_square! heightmap

Then dump it to an image file:

Worldgen::Render.heightmap heightmap, "output.png"

  5. Create a new Pull Request

Notes

Heightmaps are purely written in C for performance. If you're going to be writing code that interacts with heightmaps, you're going to have a much better time doing it in C since Ruby is a fair bit too slow once you get to larger maps (512x512 or higher).

TODO

  • Diamond Square output seems to be rougher than it should be
