gameobject-component-modify

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.

Three modification surfaces

Use whichever fits the task:

componentDiff — full SerializedMember diff (legacy, backwards compatible).
pathPatches — list of {path, value} pairs routed through Reflector.TryModifyAt; atomic per-path modification, multiple entries can target different depths.
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

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:

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.
