object-modify

# Object / Modify Modify the specified Unity Object. Allows direct modification of object fields and properties. Use 'object-get-data' first to inspect the object structure before modifying. ## Three modification surfaces Use whichever fits the task: 1. `objectDiff` — 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` → `objectDiff`. 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 object-modify --input '{ "objectRef": "string_value", "objectDiff": "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 object-modify --input-file args.json > ``` > > Or pipe via stdin (recommended): > ```bash > unity-mcp-cli run-tool object-modify --input-file - <<'EOF' > {"param": "value"} > EOF > ``` ### Troubleshooting If `unity-mcp-cli` is not found, either install it globally (`npm ...
