GameObject / Component / Destroy

Destroy one or many components from target GameObject. Can't destroy missed components. Use 'gameobject-find' tool to find the target GameObject and 'gameobject-component-get' to get component details first.

Inputs

• gameObjectRef — the host GameObject.
• destroyComponentRefs — ComponentRefList of components to destroy (matched against the GameObject's components).

Behavior

Iterates go.GetComponents<Component>(), skipping null entries (missing scripts). For each non-null component that matches one of destroyComponentRefs, the tool snapshots a ComponentRef, calls Object.DestroyImmediate, and records the destroyed reference. If no component matches at all, throws with the help text from Error.NotFoundComponents (which includes a preview of all available components on the GameObject).

How to Call

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

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool gameobject-component-destroy --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool gameobject-component-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.

Input

Name	Type	Required	Description
gameObjectRef	any	Yes	Find GameObject in opened Prefab or in the active Scene.
destroyComponentRefs	any	Yes	Component reference array. Used to find Component at GameObject.
