Procedural Toolkit v0.1.9

Procedural Toolkit is a collection of instruments for development of procedural generation systems in Unity game engine. It is free, open source and works with Unity Personal license.

Warning: This is a programming toolkit, editor support is limited.

Installation instructions

Requires Unity 5.4 or later. Tested on Windows, WebGL, Android and iOS. UnityScript interoperability is not supported.

You can install Procedural Toolkit from any of the following sources:

Import from the Asset Store
Download from Releases page. Same packages as in the Asset Store.
Clone/download repository from GitHub. In this case you will have to create a subfolder for toolkit (e.g. \Assets\ProceduralToolkit).

Folder containing example classes and scenes (ProceduralToolkit\Examples) can be safely removed. The same is true for ProceduralToolkit\Shaders, if you are not using examples. Removing ProceduralToolkit\Editor will leave you with code-only toolkit.

After installation you can import ProceduralToolkit namespace and start building your own PCG systems:

using UnityEngine;
using ProceduralToolkit;

public class Example : MonoBehaviour
{
    private void Update()
    {
        Debug.Log(string.Format("<color=#{0}>{0}</color>", RandomE.colorHSV.ToHtmlStringRGB()));
    }
}

Classes

ArrayE: Array extensions.
ColorE: Color extensions, HTML colors.
ColorHSV: Representation of color in HSV model.
DebugE: Drawing methods similar to Debug.
Directions: Enum with directions along three axes.
Draw: Collection of drawing method-independent generic drawing algorithms.
GizmosE: Drawing methods similar to Gizmos.
GLE: Drawing wrappers over GL.Vertex which follow Gizmos convention.
MeshDraft: Helper class for mesh generation.
MeshDraftPrimitives: Constructors for MeshDraft primitives.
MeshE: Mesh extensions.
MeshPrimitives: Constructors for Mesh primitives.
PTUtils: Various utility methods.
RandomE: Value generators and extensions for collections.
TextureE: Texture extensions and constructors.
Vector2Int: Vector2 analogue with integer components.
VectorE: Vector extensions.

Editor classes

ProceduralToolkitMenu: Submenu with constructors for primitives at GameObject > Procedural Toolkit and about window at Help > About Procedural Toolkit.
MeshFilterExtension: Mesh saving utility available at MeshFilter context menu > Save Mesh.
