Building

For the most part, the module gets built along with godot. However, you will need to build the FastNoise2 library first. It is on the road map to have it built as part of godot's build process, but at this point it still needs to be manually built.

Pre-requisites

• Scons

Building FastNoise.lib

git checkout git@github.com:zak-grumbles/gd_fastnoise2.git
cd gd_fastnoise2
git submodule update --init
cd FastNoise2
scons

Options

Along with the built-in scons options, these additional options are defined

• use_llvm=yes - Compile using llvm/clang

Including in Godot

As long as this repo is cloned into either the godot/modules directory or in a custom_modules directory it will be picked up along with the built-in modules when godot is built.

Usage

This is a minimal GDScript example using a simplex source and an FBm fractal to generate a 256x256 grid of 2D noise.

var gen : FNGenerator = FNGenerator.new_generator(FNGenerator.GeneratorType.Simplex);
var frac : FNFractal = FNFractal.new_fractal(FNFractal.FractalType.FBm);

frac.set_source(gen);

var data : PackedFloat32Array = frac.gen_uniform_grid_2D(
  0, 0, 256, 256, 0.2, 1337
);
