Unity Reference CodeLens

Display Unity references directly on your C# methods - instantly see which scenes, prefabs, buttons, and GameObjects are using each method.

Features

• CodeLens on Methods: See reference counts directly above your C# methods
• Detailed Information: Click to view file name, GameObject name, and hierarchy path
• Auto-Detection: Automatically scans .unity (scene) and .prefab files
• Real-time Updates: File watcher updates references when Unity files change
• Quick Navigation: Click on a reference to open the Unity file at the exact line

How It Works

1. Open a Unity project in VS Code
2. Open any C# script file
3. Methods referenced in Unity files will show a CodeLens above them
4. Click on the CodeLens to see detailed reference information
