🌀 Circular menus in the Unity Editor

Jump to heading # Introduction

This weekend I was working in Blender and noticed their easy to use circular menu. By pressing a button, the menu appears and then by pointing your mouse in a direction, you can select one of the options.

Using UI Toolkit and the new Vector API I added a circular menu to the Unity Editor. I hooked it up to my scene view debug views which allows me to quickly switch between views.

The circular menu has the following features

• nested radial menus
• a label showing the current 'directory'
• a mouse angle indicator
• hover highlights

The code for this was inspired by BennyKok's original prototype. A big thank you to them for sharing their original code. You can find the code that I used for my circular menu here.

⚠️ Use this code at your own risk! It was quickly thrown together, is a bit messy and may contain bugs.

The gist contains 3 scripts

• CircularMenu.cs
• CircularMenuButton.cs
• CircularMenuAttribute.cs

You can add a method to the circular menu simply by using the following method attribute and specifying a path and an icon.

[CircularMenu(Path = "Debug Views/Normals", Icon = "d_DirectionalLight Icon")]
public static void ShowDebugNormals()
{
    EnableDebugView(true);
    SetDebugView(DebugView.Normals);
}

That's all! Now that I am using this circular menu in my own project I will probably continue iterating on it and updating the gists as well.
