CE Procgen

CE.Procgen provides deterministic random, noise, and layout generation tools for synchronized procedural content.

Quick Start

using UdonSharp;
using UdonSharp.CE.Procgen;
using UnityEngine;

public class ProcgenExample : UdonSharpBehaviour
{
    public int seed = 1234;

    void Start()
    {
        CERandom rng = new CERandom(seed);
        CENoise.Initialize(seed);

        float h = CENoise.Fractal2D(10f, 20f, octaves: 4);
        Vector3 randomDir = rng.OnUnitSphere();
        Debug.Log("Noise: " + h + " dir: " + randomDir);
    }
}

Common Pitfalls

Bad

var rng = new CERandom(); // Non-deterministic seed

Good

var rng = new CERandom(seed); // Same seed yields identical results
