SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires unity-mcp-cli.

What problem does it solve? Manually creating prefabs in Unity requires repetitive editor interactions; this Skill automates converting a GameObject from the active scene into a reusable prefab asset saved at a specified project path. ## Core Features & Use Cases - Prefab Creation from Scene GameObjects: Converts any GameObject in the active scene or an opened prefab into a prefab asset saved under the Assets folder. - Optional Scene Replacement: Can replace the original GameObject in the scene with the newly created prefab instance via the replaceGameObjectWithPrefab flag. - Flexible GameObject Targeting: Locates the source GameObject by instanceID, hierarchy path, name, or asset reference. - Use Case: While building a Unity level, you configure an enemy character in the scene and want to reuse it. Invoke this Skill to save it as 'Assets/Prefabs/Enemy.prefab' and replace the scene instance with the prefab. ## Quick Start Use the assets-prefab-create tool to save the GameObject named 'Enemy' from the active scene as a prefab at Assets/Prefabs/Enemy.prefab.

Frequently Asked Questions about assets-prefab-create

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I create a prefab from a GameObject in Unity programmatically?▼

Use the assets-prefab-create tool via unity-mcp-cli, providing a prefabAssetPath like 'Assets/Prefabs/MyPrefab.prefab' and a gameObjectRef identifying the source GameObject. The tool saves the prefab asset and returns an AssetObjectRef.

How do I find the GameObject to convert into a prefab?▼

Use the gameobject-find tool first to locate the target GameObject, then reference it by instanceID, hierarchy path, or name in the gameObjectRef parameter. InstanceID is the recommended priority for identification.

Can I replace the scene GameObject with the new prefab instance?▼

Yes, set the replaceGameObjectWithPrefab parameter to true. The original GameObject in the scene will be replaced by an instance of the newly created prefab asset.

What should I do if unity-mcp-cli is not found?▼

Install it globally with 'npm install -g unity-mcp-cli' or run it via 'npx unity-mcp-cli'. Refer to the unity-initial-setup skill for detailed installation instructions.

What format must the prefab asset path use?▼

The prefabAssetPath must start with 'Assets/' and end with the '.prefab' extension, for example 'Assets/Path/To/Prefab.prefab'. Paths outside the Assets folder are not valid targets.
