Locked Prefab Tools

⭐ Key Features

✔ Lock / Unlock Icon in the Hierarchy

• Displays a Lock / Unlock icon next to Prefab Instance Root GameObjects.
• Clicking the icon toggles the lock state immediately.
• Icon texture and color change based on the current lock state.

✔ Lock the Entire Prefab Instance Hierarchy (Root + Children)

When locked, every GameObject in the prefab instance is set to HideFlags.NotEditable, preventing:

• Moving / deleting objects in the Hierarchy
• Modifying components in the Inspector
• Changing child object structure

This enforces the intention: “Do not modify this prefab” at the editor level.

✔ Automatic Lock Inheritance From Parent Prefabs

• If any parent transform has an active LockedPrefabInstance, children are automatically treated as locked and do not display a separate icon.
• Locking the parent protects the entire nested hierarchy.

✔ Automatic Settings Asset (ScriptableObject)

• When the asset is imported, a Settings ScriptableObject is created automatically.
• Access via: Tools → Locked Prefab Tools → Settings
• You can customize:Lock / Unlock icon textures
  Icon colors

You can easily replace the icon style to match your project theme.

✔ Editor-Only — No Runtime Impact

• Works only inside the Unity Editor.
• Does not affect builds, performance, or runtime behavior.
