Gameobject Find

GameObject / Find

Finds specific GameObject by provided information in opened Prefab or in a Scene. First it looks for the opened Prefab, if any Prefab is opened it looks only there ignoring a scene. If no opened Prefab it looks into current active scene. Returns GameObject information and its children. Also, it returns Components preview just for the target GameObject.

Toggles (all default false to keep responses small)

• includeData — full editable GameObject data (tag, layer, etc.).
• includeComponents — attached components references.
• includeBounds — 3D bounds.
• includeHierarchy — hierarchy metadata.
• hierarchyDepth (default 0) — depth of the hierarchy to include. 0 = target only, 1 = one layer below, etc.

Path-scoped reads (token-saving)

Supply paths (a list of paths) to read only the listed fields/elements via Reflector.TryReadAt, or viewQuery (a ViewQuery) to navigate to a subtree and/or filter by name regex / max depth / type via Reflector.View. When either is supplied, the result populates Data on the returned GameObjectData and overrides includeData (which would otherwise produce a full recursive serialization). These two parameters are mutually exclusive — supply at most one.

Path syntax

fieldName, nested/field, arrayField/[i], dictField/[key]. Leading #/ is stripped.

How to Call

unity-mcp-cli run-tool gameobject-find --input '{
  "gameObjectRef": "string_value",
  "includeData": false,
  "includeComponents": false,
  "includeBounds": false,
  "includeHierarchy": false,
  "hierarchyDepth": 0,
  "paths": "string_value",
  "viewQuery": "string_value"
}'

> For complex input (multi-line strings, code), save the JSON to a file and use: > ``bash > unity-mcp-cli run-tool gameobject-find --input-file args.json > ` > > Or pipe via stdin (recommended): > `bash > unity-mcp-cli run-tool gameobject-find --input-file - {"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.

Input

| Name | Type | Required | Description | |------|------|----------|-------------| | gameObjectRef | any | Yes | Find GameObject in opened Prefab or in the active Scene. | | includeData | boolean | No | Include editable GameObject data (tag, layer, etc). | | includeComponents | boolean | No | Include attached components references. | | includeBounds | boolean | No | Include 3D bounds of the GameObject. | | includeHierarchy | boolean | No | Include hierarchy metadata. | | hierarchyDepth | integer | No | Determines the depth of the hierarchy to include. 0 - means only the target GameObject. 1 - means to include one layer below. | | paths | any | No | Optional. List of paths to read individually via Reflector.TryReadAt. When supplied, replaces 'includeData'-style full serialization with a path-scoped aggregate. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Mutually exclusive with 'viewQuery'. | | viewQuery | any | No | Optional. View-query filter routed through Reflector.View. When supplied, replaces 'includeData'-style full serialization with the filtered subtree. Mutually exclusive with 'paths'. |
