Unity GameObject Skills

BATCH-FIRST: Use *_batch skills when operating on 2+ objects to reduce API calls from N to 1.

Guardrails

Mode: Full-Auto required

DO NOT (common hallucinations):

• gameobject_move / gameobject_rotate / gameobject_set_scale do not exist → use gameobject_set_transform (handles position, rotation, and scale together)
• gameobject_set_position does not exist → use gameobject_set_transform with posX/posY/posZ
• gameobject_add_component does not exist → use component_add (component module)
• gameobject_get_transform does not exist → use gameobject_get_info (returns position/rotation/scale)

Routing:

• To add/remove components → use component module
• To set material/color → use material module
• To search objects by name/tag/component → gameobject_find (this module) or scene_find_objects (scene module, Semi-Auto)

Object Targeting: All single-object skills accept three identifiers: name (string), instanceId (int, preferred for precision), path (string, hierarchy path like "Parent/Child"). Provide at least one. When only name is shown in a parameter table, instanceId and path are also accepted.

Skills Overview
