gameobject-component-destroy

Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.

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.
