FastNoiseJS

FastNoiseJS provides N-API bindings for FastNoise, so you can call FastNoise functions in Node.js.

Installation

$ npm install fastnoisejs --save

Usage

const fastnoise = require('fastnoisejs')
const noise = fastnoise.Create(123)

noise.SetNoiseType(fastnoise.Simplex)

for (let x = 0; x < 10; x++) {
  for (let y = 0; y < 10; y++) {
    console.log(noise.GetNoise(x, y))
  }
}

API

For more exhaustive documentation, refer to the FastNoise wiki. The example below highlights how fastnoisejs binds FastNoise's methods and enumerated types:

#include "FastNoise.h"
#include <iostream>

int main() {
  FastNoise noise;

  noise.SetNoiseType(FastNoise::Simplex);
  std::cout << noise.GetNoise(21, 43) << std::endl;

  return 0;
}

const fastnoise = require('fastnoisejs')

const noise = fastnoise.Create()
noise.SetNoiseType(fastnoise.Simplex)

console.log(noise.GetNoise(21, 43))

Noise constructor

const fastnoise = require('fastnoisejs')

// Optional seed argument; must be an integer
const noise = fastnoise.Create(324)

Accessing enumerated types

const fastnoise = require('fastnoisejs')

// This is not an exhaustive list; read the FastNoise wiki
const enums = [
  fastnoise.Simplex,
  fastnoise.Perlin,
  fastnoise.Linear,
  fastnoise.Quintic
]

console.log(enums)

Using FastNoise instance methods

const fastnoise = require('fastnoisejs')

const noise = fastnoise.Create()

// SetNoiseType sets the algorithm for noise.GetNoise(x, y)
noise.SetNoiseType(noise.Simplex)

const noiseVals = [
  noise.GetSimplex(23, 43),
  noise.GetValue(23, 43),
  noise.GetPerlin(23, 43),
  noise.GetNoise(23, 43)
]

console.log(noiseVals)
