+## 📂 文件结构
+
+```

+├── Editor/PCHighPerformance/
+│   ├── PCHPBuildPreProcessor.cs    # 构建预处理器（自动注入）

+```
+
+---
+
+## 🎯 功能说明
+
+### 自动注入机制
+
+**触发时机**：开发者点击「生成并转换」按钮，Unity 开始构建 Windows/macOS 平台前
+
+**工作流程**：
+
+```
+构建开始
+    ↓
+PCHPBuildPreProcessor.OnPreprocessBuild() 触发
+    ↓
+Step 1: 检查 WXPCHPInitScript 是否已加载
+    ├── 已加载 → 继续
+    └── 未加载 → 报错中断（SDK 安装问题）
+    ↓
+Step 2: 打开首个启用场景
+    ↓
+Step 3: 检查场景是否已有 "WXPCHPInitScript" GameObject
+    ├── 有 → 删除重建
+    └── 没有 → 创建新 GameObject + 添加 WXPCHPInitScript 组件
+    ↓
+Step 4: 保存场景并恢复原始布局
+    ↓
+继续正常构建流程
+```
+
+---
+
+## ✅ 关键特性
+
+1. **零侵入**：不修改开发者当前打开的场景
+2. **智能检测**：自动检测是否已存在脚本/对象
+3. **SDK 内置**：脚本位于 SDK Runtime 目录，无需复制到用户项目
+4. **命名空间隔离**：使用 `WeChatWASM` 命名空间避免冲突
+
+---
+
+## 🔧 配置说明
+
+### 脚本位置
+
+```
+Assets/WX-WASM-SDK-V2/Runtime/WXPCHPInitScript.cs
+```
+
+**类名**：`WeChatWASM.WXPCHPInitScript`
+
+**作用**：运行时初始化 PC 高性能小游戏 SDK，与宿主程序通信
+
+---
+
+## 🐛 常见问题
+
+### Q: 为什么导出的工程没有 SDK 对象？
+
+检查 Console 日志：
+- ✅ `[PC高性能小游戏] ✅ 已在 XXX 中创建 WXPCHPInitScript 并添加组件` → 成功
+- ⚠️ `找不到 WXPCHPInitScript 类型` → SDK 未正确安装
+
+### Q: DLL 加载失败？
+
+**原因**：`direct_applet_sdk.dll` 必须在 **运行时** 的根目录（与 .exe 同级）
+
+**解决**：确保宿主程序启动时提供 DLL
+
+---
+
+## 📝 技术细节
+
+| 项 | 值 |
+|---|---|
+| 触发接口 | `IPreprocessBuildWithReport` |
+| 回调优先级 | `callbackOrder = 0` |
+| 支持平台 | Windows x64, macOS |
+| 场景修改策略 | 临时打开 → 注入 → 保存 → 恢复 |
+| 类全名 | `WeChatWASM.WXPCHPInitScript` |
+
+---
+
+## 🔄 更新日志
+
+### v1.1.0 (2026-03-02)
+- ✅ 重命名 `EmbeddedAppletSDK` → `WXPCHPInitScript`
+- ✅ 迁移脚本到 Runtime 目录（解决 Editor 脚本无法挂载问题）
+- ✅ 添加 `WeChatWASM` 命名空间
+- ✅ 移除模板复制机制（脚本现在内置于 SDK）
+
+### v1.0.0 (2026-03-02)
+- ✅ 实现自动注入 EmbeddedAppletSDK GameObject
+- ✅ 智能检测并复制模板脚本
+- ✅ 兼容 Windows 和 macOS 构建

+# PC高性能小游戏 - 问题排查指南
+
+## 🐛 问题1：设置面板数据被清空
+
+### 原因
+`OnLostFocus()` 时机不对，输入框的值可能还未同步到 `formInputData`
+
+### 解决方案 ✅
+已修复：在 `OnSettingsGUI()` 中添加 `GUI.changed` 检测，每次输入时自动保存
+
+---
+
+## 🐛 问题2：ShowInfo 逻辑未执行
+
+### 可能原因
+
+#### 1. DLL 未找到 (最常见 90%)
+**症状**：运行 .exe 后没有任何弹窗  
+**原因**：`direct_applet_sdk.dll` 不在 .exe 同级目录
+
+**验证**：
+```bash
+# 检查导出目录结构
+导出路径/
+├── YourGame.exe
+├── direct_applet_sdk.dll  ← 必须存在
+└── YourGame_Data/
+```
+
+**解决**：
+- 确保 DLL 在运行时根目录
+- 查看 Unity Player.log：
+  - Windows: `%APPDATA%\..\LocalLow\<CompanyName>\<ProductName>\Player.log`
+  - 搜索关键字: `[WXPCHPInitScript]` 或 `DllNotFoundException`
+
+---
+
+#### 2. GameObject 未注入 (10%)
+**症状**：构建后场景中没有 `WXPCHPInitScript` 对象
+
+**验证**：使用调试工具
+```
+Unity 菜单 → 微信小游戏 → PC高性能调试 → 检查SDK注入状态
+```
+
+**可能的问题**：
+- ❌ Build Settings 中没有启用场景
+- ❌ 构建前 `PCHPBuildPreProcessor` 未执行
+- ❌ SDK 未正确安装
+
+**解决**：
+1. 确保 Build Settings 有至少一个启用场景
+2. 查看 Console 日志：
+   ```
+   [PC高性能小游戏] 开始预处理构建...
+   [PC高性能小游戏] ✅ 已在 XXX 中创建 WXPCHPInitScript 并添加组件
+   ```
+
+---
+
+## 🔍 调试步骤（按顺序）
+
+### Step 1: 检查 SDK 注入状态
+```
+Unity 菜单 → 微信小游戏 → PC高性能调试 → 检查SDK注入状态
+```
+
+✅ 正常输出示例：
+```
+[构建场景] 启用的场景数: 1
+  ✅ 首场景: Assets/Scenes/Main.unity
+  ✅ 找到 SDK GameObject: WXPCHPInitScript
+  ✅ 挂载的脚本: WeChatWASM.WXPCHPInitScript
+
+[类型加载检查]
+  ✅ WXPCHPInitScript 类型已加载
+  程序集: WxWasmSDKRuntime
+```
+
+---
+
+### Step 2: 检查导出路径
+```
+Unity 菜单 → 微信小游戏 → PC高性能调试 → 查看导出路径
+```
+
+确认：
+- ✅ 目录存在
+- ✅ 有 .exe 文件
+
+---
+
+### Step 3: 运行 .exe 并查看日志
+
+**日志位置**：
+```
+Windows: %APPDATA%\..\LocalLow\YourCompany\YourProduct\Player.log
+Mac: ~/Library/Logs/Company Name/Product Name/Player.log
+```
+
+**搜索关键字**：
+```
+[WXPCHPInitScript]
+DllNotFoundException
+InitEmbeddedGameSDK
+```
+
+**正常日志**：
+```
+[WXPCHPInitScript] ========== Awake 被调用 ==========
+[WXPCHPInitScript] GameObject 名称: WXPCHPInitScript
+[WXPCHPInitScript] ========== 开始初始化 ==========
+[WXPCHPInitScript] Step 1: 调用 InitEmbeddedGameSDK
+[WXPCHPInitScript] InitEmbeddedGameSDK 成功
+...
+```
+
+**异常日志**：
+```
+DllNotFoundException: Unable to load DLL 'direct_applet_sdk.dll'
+  → 解决: 复制 DLL 到 .exe 同级目录
+```
+
+---
+
+## 📝 快速检查清单
+
+- [ ] Build Settings 中有启用的场景
+- [ ] 构建时 Console 有 `[PC高性能小游戏] 预处理完成!` 日志
+- [ ] 导出目录包含 `.exe` 和 `direct_applet_sdk.dll`
+- [ ] 运行 .exe 后有弹窗或 Player.log 有日志
+

+
+## 💡 常见错误代码
+
+| 错误信息 | 原因 | 解决方法 |
+|----------|------|----------|
+| `DllNotFoundException` | DLL 未找到 | 复制 DLL 到 .exe 同级目录 |
+| `EntryPointNotFoundException` | 函数不存在 | 检查 DLL 版本是否匹配 |
+| `找不到 WXPCHPInitScript 类型` | SDK 未安装 | 重新导入 WX-WASM-SDK-V2 |
+| `GetActiveWindow 返回空句柄` | 窗口未创建 | 延迟初始化或检查 Unity Player 设置 |
