Unity GUID Usage Finder

Find where your Unity scripts are actually used — in Scenes, Prefabs, ScriptableObjects, Animations, and more — directly inside VSCode.

No more guessing. No more opening Unity just to track references.

✨ Features

🔍 Find Script Usages by GUID

Right-click any .cs file → Find Script Usages

• Scans Unity serialized files (.prefab, .unity, .asset, etc.)

• Finds all references using the script’s GUID

• Groups results by type:

  • Scenes
  • Prefabs
  • ScriptableObjects
  • Animations / Animators
  • Materials

📂 Interactive Results Panel

• Click any result → jumps to file + line
• Shows GameObject name (when available)
• Grouped and counted:

Prefabs (12)
Scenes (3)

🔎 Smart Filtering

• Filter by:

  • File name
  • GameObject name

• Live filtering in sidebar

• Visual indicator:

Filter: "enemy" — 6 match(es)

• Click the filter row to edit it
• Clear button auto-hides when not needed

⚡ Fast Scanning

• Configurable batch size
• Progress indicator + cancel support

🔄 Auto Refresh

• Automatically updates results when Unity assets change
• Debounced to avoid excessive rescans

🚀 Why this exists

Unity knows where scripts are used. VSCode doesn’t.

This bridges that gap.
