Unity Gameobject Agent Skill

Create and manipulate GameObjects — create, delete, move, rotate, scale, parent, find, rename, batch-edit. Use when building or restructuring a scene hierarchy, spawning or removing objects, or adjusting transforms, even if the user doesn't say "GameObject". 创建与操控 GameObject(增删、移动、旋转、缩放、父子、查找、重命名、批量编辑);当用户要搭建或调整场景层级、新建或删除物体、修改 Transform 时使用。

Unity GameObject Skills

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

Operating Mode

Approval：本模块多为 SkillMode.FullAuto，调用需用户 grant；grant 后服务端一步执行并返结果。
Auto / Bypass：直接执行。
含 NeverInSemi 高危 skill：gameobject_delete / gameobject_delete_batch（标记 Operation.Delete）。这些在 Approval/Auto 下返 MODE_FORBIDDEN，仅 Bypass 或用户 Allowlist 命中可调。

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, SkillMode.SemiAuto)

> Object Targeting: All single-object skills accept entityId (string, Unity 6000.4+ preferred — returned by all object skills), name (string), instanceId (int, Unity < 6000.4 preferred), and path (string, hierarchy path like "Parent/Child"). Provide at least one. Priority: entityId > instanceId > path > name. On Unity 6000.4+ use entityId — instanceId is reported as 0. When only name is shown in a parameter table, entityId, instanceId, and path are also accepted.
