UIGenerator Workflow

When to Use This Skill

• User asks to change how UI is generated from JSON, add new layer types, or adjust button/sprite behavior.
• User mentions UIGenerator, Tools/UI Generator, default sprite folder, or generating prefabs from design JSON.
• Adding or changing bindings (e.g. CustomButton, ClickAudio, ClickScaleAnim) for generated buttons.
• Post-prefab workflow: hierarchy organization by rect overlap, moving prefab to Assets/Game/UI, or generating BaseUIView partial script.
• Optimizing node names in an existing prefab (e.g. “优化 GameVictoryPanel.prefab 的节点名称”): prefer direct YAML edit of the .prefab file; see 1.5 优化已有 prefab 的节点名称. By default, only optimize functional components (_btn/_txt/_img/_toggle/_state); skip non-functional (decorative) nodes unless user asks for full optimization.

Entry Points and Flow

1. Menu（可用 MCP 直接执行，无需改代码）

   • Tools/UI Generator/Generate from JSON — open file panel, pick JSON under Assets.
   • Assets/UI Generator/Generate UI — context menu on selected .json asset（先选中 JSON 再执行）.
   • MCP：先选中 JSON，再 execute_menu_item("Assets/UI Generator/Generate UI")；或 execute_menu_item("Tools/UI Generator/Generate from JSON") 用文件对话框选 JSON。

2. Pipeline（自动按顺序执行）

   • UIGeneratorMenu.GenerateUIPrefab(jsonPath) 加载 UIGeneratorSettings.Instance，构建 UIGeneratorConfig，创建 UIGenerator(config)，调用 GenerateUIPrefab(jsonPath)。
   • 在 UIGenerator.GenerateUIPrefab 内自动顺序为：
     1. 创建所有 layer 节点；
     2. Hierarchy organization（RebuildHierarchyByRectContainment）按 rect 覆盖关系整理树状层级；
     3. 节点名称精简（SimplifyNodeNames）按 1.5 的命名规则对 _btn/_txt/_img/_toggle/_state 节点改名；
     4. 返回根 GameObject。
   • Menu 将根节点 SaveAsPrefabAsset 到 settings.outputPath，销毁临时根。
   • 保存后可选的后续步骤：move to UI folder（若存在）→ 检查是否存在对应界面脚本（见下方）→ optional BaseUIView script generation。

3. Settings (preset)

   • UIGeneratorSettings (ScriptableObject): Tools/UI Generator/Settings or load from Assets/Game/Editor/UIGenerator/UIGeneratorSettings.asset.
   • Fields: outputPath, defaultTMPFont, defaultSpriteFolder.
   • Config is built in editor from Settings (e.g. config.DefaultSpriteFolder = settings.defaultSpriteFolder). Paths use forward slashes.

Generator Structure

• UIGenerator (namespace Game.Editor.UIGenerator): takes UIGeneratorConfig, produces a root GameObject (Canvas + root with artboard name).
• Layer types (from JSON type and naming):
  • Text: LayerData.IsTextLayer (type == "textLayer") → CreateTextLayer (TextMeshProUGUI, name lower + _txt).
  • Shape: IsShapeLayer → CreateShapeLayer (Image, default color from config).
  • Image: IsImageLayer (type == "layer") → CreateImageLayer (Image, sprite load; optional button + triggers).

Sprite Loading (Image layers)

• LoadSprite(layerName, jsonPath):
  1. Try JSON directory + layerName with extensions .png, .jpg, .jpeg (paths normalized to Assets, forward slashes).
  2. If not found and config.DefaultSpriteFolder is set: AssetDatabase.FindAssets("t:Sprite", new[] { folder }), then match by filename without extension (case-insensitive) to RemoveExtension(layerName).
• Use config.DefaultSpriteFolder from Settings’ defaultSpriteFolder so “file management preset” controls fallback folder.

Button and Trigger Bindings

• Image layers whose name contains _btn_ get:
  1. CustomButton (reflection: GetTypeFromAssemblies("CustomButton")).
  2. BindButtonTriggerIfMissing(obj, "ClickAudio") and BindButtonTriggerIfMissing(obj, "ClickScaleAnim") — add component only if missing.
• CustomButton discovers ButtonClickTrigger via GetComponentsInChildren<ButtonClickTrigger>(), so ClickAudio and ClickScaleAnim on the same GameObject are used automatically.
• Use GetTypeFromAssemblies(typeName) for any runtime type (Assembly-CSharp or current domain); BindButtonTriggerIfMissing only adds when component is absent.

Conventions

• Paths: Path.Combine(...).Replace('\\', '/') or string.Replace('\\', '/') for Unity/Assets paths.
• Naming: _icon_ in layer name → Image raycastTarget = false. _btn_ → button + triggers.
• Text layers: object name = nameWithoutExtension.ToLower() + "_txt".
• Design resolution: set from artboard bounds; position/size conversion uses config.DesignResolution.

Post-Prefab Workflow (after prefab is generated)

执行 UIGenerator 时，以下步骤按顺序自动执行（保存前在内存中完成）：1. Hierarchy organization → 1.5 节点名称精简（代码中 SimplifyNodeNames，与 1.5 命名规则一致）→ 保存 prefab。保存后：2. Move prefab to UI folder (if applicable) → 3. 检查是否存在对应界面脚本 → 4. Optional: BaseUIView script generation。

• 3. 检查是否存在对应界面脚本（生成好界面后必须执行）：

  • 根据生成的 prefab 名称（如 NoAdsPopup.prefab）得到面板名 {PanelName}（即文件名无扩展名）。
  • 检查路径 Assets/Game/UI/{PanelName}/Scripts/{PanelName}.cs 是否存在（若 prefab 在 Assets/Game/UI/{X}/Resources/ 下，则 PanelName 取 X 或 prefab 文件名；若在 Generated 等通用目录，则 PanelName = prefab 文件名无扩展名，并检查是否存在 Assets/Game/UI/{PanelName}/ 及其中 Scripts）。
  • 若不存在：按 4. 创建对应名称脚本流程 在 Assets/Game/UI/{PanelName}/Scripts/ 下创建 {PanelName}.cs（参考 StartPanel.cs 的继承与 Create/OnOpen 结构）。
  • 若已存在：无需创建，后续可在 prefab 根节点挂该脚本并做 Generate UI Components / Bind Components。

• MCP 可做：manage_asset(action="get_info"|"search") 查 prefab 路径与资源；直接读取 Assets/.../xxx.prefab 的 YAML 分析层级与名称；manage_scene 在场景中创建/调整物体。对已有 prefab 文件做 hierarchy/改名 若项目未提供对应菜单，则需加菜单或改代码；有菜单时用 execute_menu_item 触发即可。

1.5 节点名称精简（生成时自动执行；已有 prefab 可改 YAML）

• 生成时自动执行：在 UIGenerator 流程中，保存 prefab 前会先执行 SimplifyNodeNames；仅对原本就带 _btn/_txt/_img/_toggle/_state 后缀且组件匹配的节点做全面优化，其他节点做简单优化（不增加后缀）。

• 已有 prefab 单独优化时：当用户要求「优化某 prefab 的 Hierarchy 节点名称」且不重新跑生成时，优先通过直接编辑 prefab 的 YAML 文件完成，不修改 C# 脚本。

• 优先跳过非功能性组件：

  • 功能性组件（需优先优化）：带 _btn、_txt、_img、_toggle、_state 且组件匹配的节点，BaseUIViewEditor 会扫描绑定，必须优化以便生成字段。
  • 非功能性组件（可优先跳过）：纯装饰（如 pic_xxx、bak_xxx、icon_xxx 无后缀）、容器（Content、Root 等）、背景图等。默认不修改，除非用户明确要求「全部优化」或「包括装饰/背景」。
  • 有要求再改：用户只说「优化节点名称」时，仅处理功能性组件；用户说「全部优化」「包括非功能组件」「连装饰一起改」时，再对非功能性节点做简单优化。

• 适用场景：对 Assets/Game/Prefabs/UI/Generated/xxx.prefab 或 Assets/Game/UI/xxx/Resources/xxx.prefab 等已有 prefab 做节点命名优化。

• 做法：

  1. 用 read_file 读取目标 .prefab 文件（Unity 预制体为 YAML 格式）。
  2. 在文件中找到所有 m_Name: 原名称（GameObject 的 serialized 名称）。
  3. 若用户未要求「全部优化」，则只对功能性组件（_btn/_txt/_img/_toggle/_state）应用命名规则；非功能性节点跳过。
  4. 按下面「命名规则」对节点做字符串替换（如 search_replace），将 m_Name: 原名称 改为 m_Name: 新名称。
  5. 保存后 Unity 刷新即可生效；无需改任何脚本。

• 命名规则（分两类）：

  • 原本有 _btn / _txt / _img / _toggle / _state 后缀的（且组件匹配）：全面优化。保留该后缀，中间部分：去掉 UI_、UI_L_、面板/artboard 名、尾部 _01/_02 等，小写+下划线保留语义；过长文案可收束（如 thebestway..._txt → quote_txt）。便于 BaseUIViewEditor 识别。
  • 其他对象（无上述后缀）：简单优化。仅去掉 UI_、UI_L_、尾部 _01/_02，中间小写+下划线保留语义；不增加 _img、_btn 等额外后缀。例如 UI_shengli_bak_xia_01 → bak_xia（不改为 bak_xia_img）。
  • 同组件同名区分：若多个节点精简后得到相同组件类型 + 相同名称（如两个都是 title_txt），则在名称中插入数字区分：第一个保持 title_txt，第二个为 title_2_txt，第三个为 title_3_txt，依此类推（格式：base_num_suffix）。避免 BaseUIView 生成字段重名。
  • 根节点/画板名（如 GameVictoryPanel、胜利常态2）一般不改。

• 示例映射（便于实现时对照）：

  • 有后缀（全面）：thebestwaytopredictthefutureistocreateit_txt → quote_txt；nextlevel_txt → next_level_txt；UI_shengli_btn_next_01 → next_btn（原名含 _btn，保留后缀）。
  • 无后缀（简单）：UI_shengli_bak_xia_01 → bak_xia；UI_shengli_bak_shang_01 → bak_shang；UI_shengli_pic_gongxi_01 → pic_gongxi；UI_L_shengli_pic_zhuese_01 → pic_zhuese（均不追加 _img 等后缀）。
  • 同组件同名加 num：两个 title_txt → title_txt、title_2_txt；三个 close_btn → close_btn、close_2_btn、close_3_btn。

1. Hierarchy organization (树状结构管理)

• Goal: Turn the flat list of layer GameObjects under the root into a tree by anchorPosition/rect 覆盖关系 — i.e. when one RectTransform’s rect fully contains another’s, make the contained one a child of the container (smallest containing rect wins as parent).
• Algorithm (outline):
  • Collect all direct children of the artboard root that have RectTransform.
  • For each node, compute its rect in root space (anchorMin/anchorMax + sizeDelta + anchoredPosition, or use RectTransformUtility / world corners then transform to root local).
  • Build containment: A contains B iff A’s rect fully contains B’s rect (with optional small tolerance). For each node, choose as parent the smallest node that contains it; if none, keep under root.
  • Rebuild hierarchy: set parent so that contained nodes are children of the chosen container, preserving order among siblings where needed.
• Button / UI element name simplification (与 hierarchy 同流程)
  • 只对原本有 _ 后缀的名称全面优化：名称中含下列后缀且组件匹配的节点做全面优化（去前缀、去_01、保留后缀、中间精简）。其他对象只做简单优化（去 UI_、去尾部 _01，中间小写+下划线），不增加 _img、_btn 等额外后缀。
  • Recognition (与 BaseUIViewEditor 一致)：全面优化仅针对含下列后缀且组件匹配的节点；后缀必须保留。
    • _btn + CustomButton
    • _txt + TextMeshProUGUI
    • _img + Image
    • _toggle + Toggle
    • _state（无组件要求，视为 GameObject）
  • 命名规则 (参考 BaseUIViewEditor.GetFieldName)：对上述节点，后缀在 GameObject 名上保持为 _btn / _txt / _img / _toggle / _state；中间部分：去掉 UI_、面板名/artboard 名、尾部 _01/_02 等，小写+下划线保留语义（如 setting_huang_btn、close_btn）。不要改成 PascalCase（那是 FieldName）。
  • 流程：在 hierarchy 整理前后均可；对“有后缀”节点按上规则生成新名称；“无后缀”节点仅做简单精简，不追加后缀。若新名称与当前名不同则 gameObject.name = newName（prefab 内修改后需 SetDirty/ApplyPrefab）。
• Where to implement: Either inside UIGenerator after creating all layers (before returning the root), or in a separate post-process step that runs on the prefab root after save (e.g. in UIGeneratorMenu after SaveAsPrefabAsset, open prefab, run hierarchy pass + name simplification, save). Use EditorUtility.SetDirty / prefab apply when modifying in editor.

2. Move prefab to UI folder (参考 Assets/Game/UI)

• Directory structure under Assets/Game/UI/:
  • One folder per panel/view: e.g. StartPanel, GamePanel, SettingPopup, LevelChoicePanel, Popup (shared).
  • Under each: Scripts/ (e.g. StartPanel.cs, StartPanel.Generated.cs), Resources/ or Prefabs/ (prefabs), Sprites/ (art, JSON).
• Rule: After generating prefab {fileName}.prefab (e.g. StartPanel.prefab):
  1. Check if folder Assets/Game/UI/{fileName}/ exists (e.g. Assets/Game/UI/StartPanel/).
  2. If yes: Move (or copy) the prefab into that folder under Resources/ or Prefabs/ (e.g. Assets/Game/UI/StartPanel/Resources/StartPanel.prefab). Prefer Resources if the panel is loaded at runtime via Resources.Load; use Prefabs if only referenced in editor/scenes.
  3. If no: Leave prefab in settings.outputPath (e.g. Assets/Game/Prefabs/UI/Generated), or optionally move to a global Assets/Game/UI/Resources (or similar) if you want a single place for “unassigned” generated prefabs.
• Paths: use forward slashes; create Resources or Prefabs subfolder if missing. Use AssetDatabase.MoveAsset (or delete + save to new path) and AssetDatabase.Refresh.

3. BaseUIView and script generation

• BaseUIView (in Bear.UI or project): base class for UI views. Each panel is a partial class (e.g. public partial class GamePlayPanel : BaseUIView).
• BaseUIViewEditor (Assets/Game/Editor/BaseUIViewEditor.cs): CustomEditor for BaseUIView. It:
  • Generate UI Components / Rescan & Regenerate Partial Script: scans children of the view GameObject, generates a partial file {ClassName}.Generated.cs in the same directory as the main script (via GetScriptPath → GetPartialScriptPath). The generated file declares [SerializeField] private fields for CustomButton, TextMeshProUGUI, Image, Toggle, GameObject by naming.
  • Bind Components to Inspector: after compilation, finds child objects by name and assigns them to the serialized fields (requires the partial to be compiled).
• When to generate view script:
  • If the generated prefab should become a bindable view (like GamePlayPanel, StartPanel): the root of the prefab (artboard root) must have a BaseUIView (or subclass) component. The main script (e.g. StartPanel.cs) must already exist under Assets/Game/UI/{PanelName}/Scripts/ and be a partial class inheriting BaseUIView.
  • Option A (manual): After moving prefab to Assets/Game/UI/{PanelName}/Resources/, user opens prefab, adds BaseUIView (or the existing panel script) to root, then in Inspector clicks “Generate UI Components”, waits for compile, then “Bind Components to Inspector”.
  • Option B (command): Add a menu/item (e.g. Tools/UI Generator/Generate View Script for Selected Prefab or run after Generate): ensure root has a BaseUIView component; call BaseUIViewEditor logic programmatically (e.g. get Editor via Editor.CreateEditor, invoke the method that does ScanChildObjects + GeneratePartialClassCode + SavePartialScript), then prompt user to run “Bind Components to Inspector” after compile, or run binding via reflection if safe.
• Creating a new panel from scratch: If there is no existing {PanelName}.cs under Assets/Game/UI/{PanelName}/Scripts/, either (1) add a command that creates a minimal partial class stub (e.g. public partial class {PanelName} : BaseUIView { }) and the folder structure, then run generation, or (2) document that user creates the script and folder first, then generates prefab and runs “Generate UI Components” + “Bind Components to Inspector”.

4. 创建对应名称脚本流程（参考 StartPanel.cs）

新建面板时，在 Assets/Game/UI/{PanelName}/Scripts/ 下创建与面板同名的主脚本 {PanelName}.cs，继承与结构参考 StartPanel。

• 脚本路径：Assets/Game/UI/{PanelName}/Scripts/{PanelName}.cs（PanelName 与 UI 文件夹名一致，如 StartPanel、ShopPanel、NoAdsPopup）。
• 类声明：public partial class {PanelName} : BaseUIView；如需与项目一致可加接口，例如 , IDebuger, IEventSender（参考 StartPanel）。
• 命名空间：与 StartPanel 一致，顶层类即可，无需包在 namespace 内（除非项目统一要求）。
• 常用 using：Bear.UI（BaseUIView）、Bear.EventSystem / Bear.Logger（若用接口）、Game.Events 等按需；TMPro 若用到再加。
• 必须/推荐内容：
  1. OnOpen()：public override void OnOpen() 中调用 base.OnOpen()，再挂接按钮等逻辑（如 XxxBtn.OnClick += Handler）。
  2. Create()：静态工厂方法，与 StartPanel 一致：
     var panel = UIManager.Instance.OpenUI<{PanelName}>($"{typeof({PanelName}).Name}", UILayer.Normal); return panel;
• 后续：prefab 放到该面板的 Resources 后，在 prefab 根节点挂此脚本（或 BaseUIView 子类），在 Inspector 用 BaseUIViewEditor 的「Generate UI Components」生成 {PanelName}.Generated.cs，编译后再「Bind Components to Inspector」。

参考：Assets/Game/UI/StartPanel/Scripts/StartPanel.cs（继承 BaseUIView, IDebuger, IEventSender、OnOpen、Create 写法）。

Extending the Workflow

• 先考虑 MCP：能用 execute_menu_item、manage_scene、manage_gameobject、manage_prefabs、manage_asset 等完成的（如触发生成、在场景中加物体、移动资源），不新增或修改脚本。
• New layer type: in CreateLayerGameObject add condition on layer.Type or name pattern, then a dedicated CreateXxxLayer(layer, obj, jsonPath).
• New preset: add field to UIGeneratorSettings and map it to UIGeneratorConfig in UIGeneratorMenu.GenerateUIPrefab.
• New button trigger: ensure type is discoverable by GetTypeFromAssemblies and call BindButtonTriggerIfMissing(obj, "TypeName") in the same _btn_ block.
• Post-prefab: implement hierarchy pass (rect containment → parent choice → reparent), then move prefab under Assets/Game/UI/{Name}/Resources/ or Prefabs/ when folder exists, then optionally hook into BaseUIViewEditor for script generation/binding.
