What is this?

This editor tool adds a graph editor to Unity to create procedural noise using the FastNoise2 library. This is intended to work like the built-in graph editor of FastNoise2 but inside Unity.

Compatibility

This editor tool has been tested only with FastNoise2 v0.10.0-alpha and Unity 2022 LTS.

Features

• Noise tree assets.
• Nodes are created using the metadata from FastNoise2.
• One editor window per graph for easy editing.
• Copy and paste support.

How to install

• First you have to import the FastNoise2 library into your Unity project. To do that go to the tags page in the FastNoise2 repository, select a version (I recommend v0.10.0-alpha), and download the zip file according to your platoform. Now:
  • If you are on windows, copy the FastNoise.dll and paste it in your Unity Assets folder.
• You don't need to install the C# bindings of FastNoise2 because they are included in this package.
• Now you need to install this package. In Unity, go to Window -> Package Manager
• Click the "+" icon in the top left
• Choose "Add package from git URL"
• Paste https://github.com/carlo697/FastNoise2GraphEditor.git

How to use

• Create a Fast Noise tree asset by right clicking on the Project window -> Create -> Fast Noise Tree.
• Double click the asset to open the editor window.
• Add new nodes and connect them to the output node.
• Now in a MonoBehaviour:
  • Add: using FastNoise2Graph;
  • Add a public field: public NoiseTree noiseTree;
  • Save your script and now you can drag and drop the previously created noise tree into the field.
• Once you have a reference to the noise tree in a script, now you can call: noiseTree.GetFastNoise() to get a FastNoise instance.
• With a FastNoise instance now you can generate procedural noise by using its methods:
  • GenSingle2D
  • GenSingle3D
  • GenSingle4D
  • GenUniformGrid2D
  • GenUniformGrid3D
  • GenUniformGrid4D
  • GenPositionArray2D
  • GenPositionArray3D
  • GenPositionArray4D
