# GameObject / Duplicate
|
|
|
|
Duplicate GameObjects in opened Prefab or in a Scene. Use 'gameobject-find' tool to find the target GameObjects first.
|
|
|
|
## Inputs
|
|
|
|
- `gameObjectRefs` — `GameObjectRefList` of source GameObjects.
|
|
|
|
## Behavior
|
|
|
|
Resolves every input ref on the main thread (throwing on any unresolved entry to keep the batch atomic). Sets `Selection.entityIds`/`instanceIDs` to the sources and invokes `Unsupported.DuplicateGameObjectsUsingPasteboard()` (Unity's canonical duplicate routine). Marks every distinct affected scene dirty so the duplicated objects are saved with the scene. Returns refs to the sources (the duplicates are reachable via the post-call `Selection`).
|
|
|
|
## How to Call
|
|
|
|
```bash
|
|
unity-mcp-cli run-tool gameobject-duplicate --input '{
|
|
"gameObjectRefs": "string_value"
|
|
}'
|
|
```
|
|
|
|
> For complex input (multi-line strings, code), save the JSON to a file and use:
|
|
> ```bash
|
|
> unity-mcp-cli run-tool gameobject-duplicate --input-file args.json
|
|
> ```
|
|
>
|
|
> Or pipe via stdin (recommended):
|
|
> ```bash
|
|
> unity-mcp-cli run-tool gameobject-duplicate --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.
