# [znoise](https://github.com/zig-gamedev/znoise)

Zig build package and bindings for [FastNoiseLite](https://github.com/Auburn/FastNoiseLite)

## Getting started

Example `build.zig`:

```zig

pub fn build(b: *std.Build) void {

    const exe = b.addExecutable(.{ ... });

    const znoise = b.dependency("znoise", .{});

    exe.root_module.addImport("znoise", znoise.module("root"));

    exe.linkLibrary(znoise.artifact("FastNoiseLite"));

}

```

Now in your code you may import and use znoise:

```zig

const znoise = @import("znoise");

pub fn main() !void {

    ...

    {

        const gen = znoise.FnlGenerator{};

        const n2 = gen.noise2(0.1, 0.2);

        const n3 = gen.noise3(1.0, 2.0, 3.0);

        var x: f32 = 1.0;

        var y: f32 = 2.0;

        var z: f32 = 3.0;

        gen.domainWarp3(&x, &y, &z);

    }

    {

        const gen = znoise.FnlGenerator{

            .seed = 1337,

            .frequency = 0.01,

            .noise_type = .opensimplex2,

            .rotation_type3 = .none,

            .fractal_type = .none,

            .octaves = 3,

            .lacunarity = 2.0,

            .gain = 0.5,

            .weighted_strength = 0.0,

            .ping_pong_strength = 2.0,

            .cellular_distance_func = .euclideansq,

            .cellular_return_type = .distance,

            .cellular_jitter_mod = 1.0,

            .domain_warp_type = .opensimplex2,

            .domain_warp_amp = 1.0,

        };

        const n = gen.noise2(0.1, 0.2);

    }

}

```
