GameObject / Destroy

Destroy GameObject and all nested GameObjects recursively in opened Prefab or in a Scene. Use 'gameobject-find' tool to find the target GameObject first.

Behavior

Validates the gameObjectRef, resolves it on the main thread, then calls Object.DestroyImmediate (the immediate variant is required for Editor-mode operations). Returns a DestroyGameObjectResult containing DestroyedName, DestroyedPath, and DestroyedInstanceId so the caller has a record of what was removed.

How to Call

unity-mcp-cli run-tool gameobject-destroy --input '{
  "gameObjectRef": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use: ``bash unity-mcp-cli run-tool gameobject-destroy --input-file args.json ``

>

Or pipe via stdin (recommended): ``bash unity-mcp-cli run-tool gameobject-destroy --input-file - <<'EOF' {"param": "value"} EOF ``

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.
