description	Manage Unity scenes — create, load (single/additive), save, unload, switch the active scene, and get scene info/hierarchy. Use when opening or saving scenes, loading additively, switching the active scene, or querying scene contents, even if the user just says "打开场景" or "切场景". 管理 Unity 场景(创建、加载、叠加加载、保存、卸载、切换活动场景、获取场景信息与层级);当用户要打开或保存场景、叠加加载、切换活动场景、或查询场景内容时使用。 Use when this capability is needed.

Unity Scene Skills

Control Unity scenes - the containers that hold all your GameObjects.

Operating Mode

• Approval：本模块 Mixed —— scene_get_info / scene_get_hierarchy / scene_get_loaded / scene_find_objects 标 SkillMode.SemiAuto，可直接执行；scene_screenshot / scene_unload / scene_set_active 未设 Mode 字段（默认 FullAuto），Approval 模式下需 grant。
• Auto / Bypass：FullAuto 直接执行。
• 含 NeverInSemi 高危 skill：scene_create / scene_load / scene_save（标 RiskLevel="high"，因为切换/覆盖整个场景文件影响范围极大）。这些在 Approval/Auto 下返 MODE_FORBIDDEN，仅 Bypass 或 Allowlist 命中可调。

DO NOT (common hallucinations):

• scene_delete / scene_rename do not exist → delete scene files via asset_delete, rename via asset_move
• scene_list does not exist → use scene_get_loaded (loaded scenes) or asset_find with t:Scene (all scene assets)
• scene_find_objects is a simple name/tag/component filter; for regex/layer/path search use gameobject_find (SkillMode.FullAuto)

Routing:

• For detailed hierarchy tree → use perception module's hierarchy_describe
• For scene statistics → use perception module's scene_summarize
• For screenshot → scene_screenshot (this module) captures the Game View final composited image (all cameras + UI; in Play mode this is the live runtime frame); camera_screenshot (camera module, SkillMode.FullAuto) renders a single Game Camera off-screen

Skills

scene_create

Create a new scene.

Parameter	Type	Required	Description
scenePath	string	Yes	Path for new scene (e.g., "Assets/Scenes/MyScene.unity")

scene_load

Load a scene.

Parameter	Type	Required	Default	Description
scenePath	string	Yes	-	Scene asset path
additive	bool	No	false	Load additively (keep current scene)

scene_save

Save the current scene.

Parameter	Type	Required	Description
scenePath	string	No	Save path (null = save current)

scene_get_info

Get current scene information.

No parameters.

Returns: {success, name, path, isDirty, rootObjectCount, rootObjects: [name]}

scene_get_hierarchy

Get full scene hierarchy tree.

Parameter	Type	Required	Default	Description
maxDepth	int	No	10	Maximum hierarchy depth

Returns: {success, hierarchy: [{name, instanceId, children: [...]}]}

scene_screenshot

Capture a screenshot of the Game View — the final composited frame of all cameras + UI. In Play mode this is the live runtime image, not the Scene/editor view. For a single Game Camera's render use camera_screenshot instead.

Parameter	Type	Required	Default	Description
filename	string	No	"screenshot.png"	Bare filename only (no path separators); saved under Assets/Screenshots/
width	int	No	1920	Image width
height	int	No	1080	Image height

Returns: {success, path, width, height, isPlaying, note}. isPlaying indicates whether the frame is a live runtime image (Play mode) or a static Edit-mode frame.

Async: ScreenCapture.CaptureScreenshot writes the PNG ~1 frame later. If reading path immediately fails, wait ~200ms and retry.

scene_get_loaded

Get list of all currently loaded scenes.

No parameters.

Returns: {success, scenes: [{name, path, isActive, isDirty}]}

scene_unload

Unload a loaded scene (additive).

Parameter	Type	Required	Description
sceneName	string	Yes	Scene name to unload

scene_set_active

Set the active scene (for multi-scene editing).

Parameter	Type	Required	Description
sceneName	string	Yes	Scene name to set active

scene_find_objects

Search GameObjects by name pattern, tag, or component type. For advanced search (regex, layer, path) use gameobject_find.

Parameter	Type	Required	Default	Description
namePattern	string	No	-	Name substring to match (case-insensitive)
tag	string	No	-	Filter by tag
componentType	string	No	-	Filter by component type name
limit	int	No	50	Max results to return

Returns: {success, count, objects: [{name, path, instanceId, active, tag}]}

Example Usage

import unity_skills

# Create a new scene
unity_skills.call_skill("scene_create", scenePath="Assets/Scenes/Level1.unity")

# Load an existing scene
unity_skills.call_skill("scene_load", scenePath="Assets/Scenes/MainMenu.unity")

# Load scene additively (multi-scene)
unity_skills.call_skill("scene_load", scenePath="Assets/Scenes/UI.unity", additive=True)

# Get current scene info
info = unity_skills.call_skill("scene_get_info")
print(f"Scene: {info['name']}, Objects: {info['rootObjectCount']}")

# Get full hierarchy (useful for understanding scene structure)
hierarchy = unity_skills.call_skill("scene_get_hierarchy", maxDepth=5)

# Save scene
unity_skills.call_skill("scene_save")

# Take screenshot
unity_skills.call_skill("scene_screenshot", filename="preview.png", width=1920, height=1080)

Best Practices

1. Always save before loading a new scene
2. Use additive loading for UI overlays
3. Keep scene hierarchy organized with empty parent objects
4. Use scene_get_info to verify scene state
5. Screenshots are saved under Assets/Screenshots/ (filename is a bare name; any path separators are stripped)

Exact Signatures

Exact names, parameters, defaults, and returns are defined by GET /skills/schema or unity_skills.get_skill_schema(), not by this file.
