name: gameobject-component-modify
|
|
description: Modify a specific Component on a GameObject in opened Prefab or in a Scene. Allows direct modification of component fields and properties without wrapping in GameObject structure. Use 'gameobject-component-get' first to inspect the component structure before modifying. Three modification surfaces are available (componentDiff, pathPatches, jsonPatch) — see the skill body for details.

# GameObject / Component / Modify
|
|
|
|
## Three modification surfaces
|
|
|
|
Use whichever fits the task:
|
|
|
|
1. `componentDiff` — full `SerializedMember` diff (legacy, backwards compatible).
|
|
2. `pathPatches` — list of `{path, value}` pairs routed through `Reflector.TryModifyAt`; atomic per-path modification, multiple entries can target different depths.
|
|
3. `jsonPatch` — a JSON Merge Patch (RFC 7396, extended with `[i]`/`[key]` notation) routed through `Reflector.TryPatch`; multiple fields at any depth in a single call.
|
|
|
|
When more than one is supplied they run in this order: `jsonPatch` → `pathPatches` → `componentDiff`. At least one is required.
|
|
|
|
## Path syntax
|
|
|
|
`fieldName`, `nested/field`, `arrayField/[i]`, `dictField/[key]`. Leading `#/` is stripped.
|
|
|
|
## How to Call
|
|
|
|
```bash
|
|
unity-mcp-cli run-tool gameobject-component-modify --input '{
|
|
"gameObjectRef": "string_value",
|
|
"componentRef": "string_value",
|
|
"componentDiff": "string_value",
|
|
"pathPatches": "string_value",
|
|
"jsonPatch": "string_value"
|
|
}'
|
|
```
|
|
|
|
> For complex input (multi-line strings, code), save the JSON to a file and use:
|
|
> ```bash
|
|
> unity-mcp-cli run-tool gameobject-component-modify --input-file args.json
|
|
> ```
|
|
>
|
|
> Or pipe via stdin (recommended):
|
|
> ```bash
|
|
> unity-mcp-cli run-tool gameobject-component-modify --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. |
|
|
| `componentRef` | `any` | Yes | Component reference. Used to find a Component at GameObject. |
|
|
| `componentDiff` | `any` | No | Optional. The full component data to apply (legacy path). Should contain 'fields' and/or 'props' with the values to modify.
|
|
Only include the fields/properties you want to change.
|
|
Any unknown or invalid fields and properties will be reported in the response. |
|
|
| `pathPatches` | `any` | No | Optional. List of path-scoped patches routed through Reflector.TryModifyAt. Each entry targets one field/element/entry by path. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. |
|
|
| `jsonPatch` | `any` | No | Optional. JSON Merge Patch (RFC 7396, extended with [i]/[key] keys) routed through Reflector.TryPatch. Allows multiple fields at any depth to be updated in a single call. Use '$type' for compatible-subtype replacement. |
|
|
