+# Extra2D 数据结构与算法优化计划
+
+## 概述
+针对分析发现的潜在问题，制定以下分阶段优化计划。
+
+---
+
+## 阶段一：高优先级问题修复（预计 3-4 天）
+
+### 1.1 四叉树碰撞检测优化
+**目标**: 解决 O(n²) 碰撞检测性能问题
+**文件**: `src/spatial/quadtree.cpp`
+**方案**:
+- 实现扫描线算法或 AABB 树加速碰撞检测
+- 优化节点分裂策略，避免对象过度集中
+- 添加单元测试验证性能改进
+
+### 1.2 空间哈希内存布局重构
+**目标**: 减少内存碎片，提高缓存友好性
+**文件**: `include/extra2d/spatial/spatial_hash.h`, `src/spatial/spatial_hash.cpp`
+**方案**:
+- 使用单一连续内存结构替代嵌套哈希表
+- 实现对象池复用 Cell 内存
+- 查询时使用线程本地静态缓冲区避免临时分配
+
+### 1.3 动画帧数据布局优化
+**目标**: 提高动画系统缓存命中率
+**文件**: `include/extra2d/animation/animation_frame.h`, `include/extra2d/animation/frame_property.h`
+**方案**:
+- 采用结构体数组(SoA)布局存储帧数据
+- 热数据(delay, offset)和冷数据(碰撞盒)分离
+- 使用紧凑位域替代 std::variant 存储属性
+
+### 1.4 Node 循环引用风险修复
+**目标**: 消除内存泄漏风险
+**文件**: `include/extra2d/scene/node.h`, `src/scene/node.cpp`
+**方案**:
+- 审查所有 shared_ptr 使用场景
+- 添加对象所有权文档说明
+- 考虑使用 intrusive_ptr 替代 shared_ptr
+
+---
+
+## 阶段二：中优先级优化（预计 2-3 天）
+
+### 2.1 变换矩阵脏标记传播
+**目标**: 优化深层场景树性能
+**文件**: `src/scene/node.cpp`
+**方案**:
+- 实现脏标记传播机制替代递归计算
+- 延迟计算世界变换直到实际需要
+
+### 2.2 纹理池 LRU 优化
+**目标**: 提高缓存局部性
+**文件**: `include/extra2d/graphics/texture_pool.h`
+**方案**:
+- 使用侵入式链表替代 std::list
+- 使用数组索引代替指针
+
+### 2.3 子节点排序优化
+**目标**: 减少排序开销
+**文件**: `src/scene/node.cpp`
+**方案**:
+- 使用插入排序（如果大部分已有序）
+- 或使用 std::multiset 维护有序性
+
+---
+
+## 阶段三：低优先级改进（预计 1-2 天）
+
+### 3.1 渲染命令内存优化
+**目标**: 减少 RenderCommand 内存占用
+**文件**: `include/extra2d/graphics/render_command.h`
+**方案**:
+- 类型分离的命令队列
+- 或自定义联合体替代 std::variant
+
+### 3.2 资源管理软引用缓存
+**目标**: 减少资源重复加载
+**文件**: `include/extra2d/resource/resource_manager.h`
+**方案**:
+- 实现 LRU 策略管理缓存
+- 软引用保留最近使用资源
+
+---
+
+## 实施顺序建议
+
+1. **首先修复内存安全问题** (Node 循环引用)
+2. **然后优化性能瓶颈** (四叉树、空间哈希)
+3. **最后进行内存布局优化** (动画帧、渲染命令)
+
+## 预期收益
+
+| 优化项 | 预期性能提升 | 内存节省 |
+|--------|-------------|----------|
+| 四叉树碰撞检测 | 50-80% (大量对象时) | - |
+| 空间哈希重构 | 20-30% | 30-40% |
+| 动画帧布局 | 15-25% | 40-50% |
+| 变换矩阵优化 | 10-20% (深层场景) | - |
+| 纹理池 LRU | - | 20-30% |
+
+---
+
+请确认此计划后，我将开始实施具体的代码修改。

-
-# 指定平台 (使用 -p 参数)
-xmake f -c -p mingw
-xmake f -c -p switch
-
-# 指定 MinGW 路径（如果不在默认位置）
-xmake f -c -p mingw --mingw=C:\mingw
-
-# 禁用示例
-xmake f --examples=n
-
-# 启用调试日志
-xmake f --debug_logs=y
-```
-
-### 安装依赖 (MinGW)
-```bash
-xmake require -y
-```
-
-### 构建项目
-```bash
-# 构建所有目标
-xmake
-
-# 构建特定目标
-xmake -r extra2d
-xmake -r push_box
-
-# 并行构建
-xmake -j4
-```
-
-### 运行程序
-```bash
-# 运行示例
-xmake run push_box
-xmake run hello_world
-```
-
-### 清理构建
-```bash
-xmake clean
-xmake f -c  # 重新配置
-```
-
-## 输出目录结构
-
-```
-build/
-├── examples/
-│   ├── hello_world/
-│   │   ├── hello_world.exe    # MinGW
-│   │   ├── hello_world.nro    # Switch
-│   │   └── assets/            # 资源文件
-│   ├── push_box/
-│   ├── collision_demo/
-│   └── spatial_index_demo/
-└── ...
-```
-
-## 关键设计决策
-
-### 1. 平台检测
-- 使用 `is_plat()` 而不是手动检测，确保与主项目一致
-- 示例脚本继承主项目的平台配置
-
-### 2. 资源处理
-- **Switch**: 使用 romfs 嵌入 NRO 文件
-- **MinGW**: 构建后复制到输出目录
-
-### 3. 依赖管理
-- **MinGW**: 使用 Xmake 包管理器 (`add_requires`)
-- **Switch**: 使用 devkitPro 提供的库
-
-### 4. 工具链隔离
-- Switch 工具链定义在单独文件中
-- 通过 `set_toolchains("switch")` 切换
-
-## 常见问题
-
-### 1. 依赖包找不到
-```bash
-xmake repo -u
-xmake require -y
-```
-
-### 2. Switch 工具链找不到
-- 确保 DEVKITPRO 环境变量设置正确
-- 默认路径: `C:/devkitPro`
-
-### 3. 平台配置不匹配
-- 使用 `xmake show` 查看当前配置
-- 使用 `xmake f -c` 重新配置
-
-### 4. MinGW 路径问题
-如果 MinGW 安装在非默认位置，使用 `--mingw` 参数指定：
-```bash
-xmake f -c -p mingw --mingw=D:\Tools\mingw64
-```
-
-### 5. Switch 库找不到
-确保在 MSYS2 中安装了必要的库：
-```bash
-pacman -S switch-sdl2 switch-sdl2_mixer switch-glm
-```
-
-## 扩展指南
-
-### 添加新示例
-1. 在 `examples/` 下创建新目录
-2. 创建 `xmake.lua` 构建脚本
-3. 在 `xmake.lua` 中添加 `includes("examples/new_example")`
-
-### 添加新平台
-1. 在 `xmake/toolchains/` 下创建工具链定义
-2. 在 `xmake.lua` 中添加平台检测逻辑
-3. 在 `xmake/engine.lua` 中添加平台配置

+# Easy2D Nintendo Switch 编译指南
+
+## 概述
+
+本文档说明如何使用 xmake 为 Nintendo Switch 编译 Easy2D 引擎及其示例程序。
+
+## 前置条件
+
+### 1. 必需工具
+
+- **devkitPro** - Nintendo Switch 开发工具包
+- **xmake** - 跨平台构建系统（v3.0.6+）
+- **devkitA64** - ARM64编译器工具链（devkitPro 的一部分）
+
+### 2. 安装 devkitPro
+
+#### Windows
+
+1. 从 https://devkitpro.org/wiki/Getting_Started/devkitPro_installer 下载 devkitPro 安装程序
+2. 运行安装程序，选择以下组件：
+   - devkitA64 (ARM64)
+   - libnx (Nintendo Switch库)
+   - mesa (OpenGL ES)
+   - tools (nacptool, elf2nro 等)
+3. 默认安装路径：`C:\devkitPro`
+
+#### Linux/macOS
+
+请参考官方文档：https://devkitpro.org/wiki/Getting_Started
+
+### 3. 验证安装
+
+```bash
+# 检查devkitPro是否正确安装
+$env:DEVKITPRO = "C:\devkitPro"  # Windows PowerShell
+export DEVKITPRO=/opt/devkitpro  # Linux/macOS
+
+# 检查工具链
+aarch64-none-elf-gcc --version  # 应该显示 GCC 版本
+
+# 检查xmake
+xmake --version  # 应该显示 v3.0.6 或更高
+```
+
+## 编译步骤
+
+### 1. 配置项目
+
+```bash
+cd C:\Users\soulcoco\Desktop\Easy2D\Easy2D-dev
+
+# 配置编译（使用Switch工具链）
+xmake config -p switch -a arm64
+
+# 或者使用默认配置
+xmake config
+```
+
+### 2. 编译核心库
+
+编译 Easy2D 静态库：
+
+```bash
+xmake build easy2d
+```
+
+**输出：**
+- Release: `build/switch/libeasy2d.a`
+- Debug: `build/switch/libeasy2dd.a`
+
+### 3. 编译示例程序
+
+#### 编译音频演示
+
+```bash
+xmake build switch_audio_demo
+```
+
+**输出：**
+- ELF: `build/switch/switch_audio_demo`
+- NACP: `build/switch/switch_audio_demo.nacp`
+- NRO: `build/switch/switch_audio_demo.nro` (Switch可执行文件)
+
+#### 编译动画演示
+
+```bash
+xmake build switch_animation_demo
+```
+
+**输出：**
+- NRO: `build/switch/switch_animation_demo.nro`
+
+### 4. 一次编译所有目标
+
+```bash
+xmake build -a
+```
+

+    -- 链接 EGL 和 OpenGL ES (mesa)
+    add_syslinks("EGL", "GLESv2", "glapi", "drm_nouveau")
+```
+
+#### 2. Easy2D 静态库配置 (行 60-134)
+
+```lua
+target("easy2d")
+    set_kind("static")
+    set_plat("switch")      -- 平台
+    set_arch("arm64")       -- 架构
+    set_toolchains("switch") -- 工具链
+    
+    add_files(SRC_DIR .. "/**.cpp")        -- 源文件
+    add_files("squirrel/squirrel/*.cpp")   -- 脚本引擎
+    add_includedirs(INC_DIR)               -- 头文件目录
+```
+
+#### 3. Switch 示例程序配置 (行 139-257)
+
+xmake 自动处理：
+- **编译** ELF 文件
+- **生成 NACP** 应用元数据
+- **转换为 NRO** (Switch 可执行格式)
+- **打包 RomFS** (资源文件系统)
+
+## 故障排除
+
+### 编译错误
+
+#### 错误：找不到 Switch 工具链
+
+```
+Error: toolchain 'switch' not found
+```
+
+**解决方案：**
+1. 确认 `DEVKITPRO` 环境变量已设置
+2. 检查 devkitPro 安装路径：`C:\devkitPro` (Windows) 或 `/opt/devkitpro` (Linux)
+3. 验证 `devkitA64/bin` 下的编译器存在
+
+#### 错误：找不到 libnx 库
+
+```
+Error: cannot find -lnx
+```
+
+**解决方案：**
+1. 验证 devkitPro 安装了 libnx 包
+2. 检查 `DEVKITPRO/libnx` 目录是否存在
+
+#### 错误：OpenGL ES 头文件缺失
+
+```
+Error: GL/gl.h: No such file or directory
+```
+
+**解决方案：**
+1. 验证 mesa 已安装：`DEVKITPRO/portlibs/switch/include`
+2. 检查 xmake.lua 中的包含目录配置
+
+### 链接错误
+
+#### 未定义的引用到 EGL 函数
+
+```
+undefined reference to 'eglInitialize'
+```
+
+**解决方案：**
+- 确保 EGL 库链接顺序正确（xmake.lua 第 93 行）
+
+### 运行时错误
+
+#### NRO 文件无法在 Switch 上运行
+
+**检查清单：**
+1. 确认 `DEVKITPRO` 环境变量设置正确

-# Extra2D API 教程 - 01. 快速开始
-
-## 简介
-
-Extra2D 是一个跨平台的 2D 游戏引擎，支持 Windows (MinGW) 和 Nintendo Switch 平台。
-
-## 最小示例
-
-```cpp
-#include <extra2d/extra2d.h>
-
-using namespace extra2d;
-
-int main(int argc, char **argv) {
-    // 1. 初始化日志系统
-    Logger::init();
-    Logger::setLevel(LogLevel::Debug);
-
-    // 2. 获取应用实例
-    auto &app = Application::instance();
-
-    // 3. 配置应用
-    AppConfig config;
-    config.title = "My Game";
-    config.width = 1280;
-    config.height = 720;
-    config.vsync = true;
-    config.fpsLimit = 60;
-
-    // 4. 初始化应用
-    if (!app.init(config)) {
-        E2D_LOG_ERROR("应用初始化失败！");
-        return -1;
-    }
-
-    // 5. 进入场景
-    app.enterScene(makePtr<MyScene>());
-
-    // 6. 运行应用
-    app.run();
-
-    return 0;
-}
-```
-
-## 核心概念
-
-### 应用生命周期
-
-```
-Logger::init() → Application::init() → enterScene() → run() → 退出
-```
-
-### 场景生命周期
-
-```
-onEnter() → onUpdate(dt) → onRender() → onExit()
-```

-# Extra2D API 教程 - 02. 场景系统
-
-## 场景基础
-
-场景(Scene)是游戏的基本组织单位，负责管理节点和渲染。
-
-### 创建场景
-
-```cpp
-#include <extra2d/extra2d.h>
-
-using namespace extra2d;
-
-class MyScene : public Scene {
-public:
-    // 场景进入时调用
-    void onEnter() override {
-        // 必须先调用父类的 onEnter()
-        Scene::onEnter();
-        
-        // 设置背景颜色
-        setBackgroundColor(Color(0.1f, 0.1f, 0.3f, 1.0f));
-        
-        E2D_LOG_INFO("场景已进入");
-    }
-    
-    // 每帧更新时调用
-    void onUpdate(float dt) override {
-        Scene::onUpdate(dt);
-        // dt 是时间间隔（秒）
-    }
-    
-    // 渲染时调用
-    void onRender(RenderBackend &renderer) override {
-        Scene::onRender(renderer);
-        // 绘制自定义内容
-    }
-    
-    // 场景退出时调用
-    void onExit() override {
-        // 清理资源
-        Scene::onExit();
-    }
-};
-```
-
-### 重要提示
-
-**必须调用 `Scene::onEnter()`**：
-```cpp
-void onEnter() override {
-    Scene::onEnter();  // 必须调用！
-    // 你的初始化代码
-}
-```
-
-如果不调用，会导致：
-- `running_` 状态未设置
-- 子节点无法正确注册到空间索引
-- 碰撞检测失效
-
-## 场景管理
-
-### 进入场景
-
-```cpp
-// 进入新场景
-app.enterScene(makePtr<MyScene>());
-
-// 替换当前场景（带过渡效果）
-app.scenes().replaceScene(
-    makePtr<PlayScene>(),
-    TransitionType::Fade,  // 淡入淡出
-    0.25f                   // 过渡时间（秒）
-);
-```
-
-### 场景过渡类型
-
-```cpp
-enum class TransitionType {
-    None,       // 无过渡
-    Fade,       // 淡入淡出
-    SlideLeft,  // 向左滑动
-    SlideRight, // 向右滑动
-    SlideUp,    // 向上滑动
-    SlideDown   // 向下滑动
-};
-```
-
-## 场景配置
-
-### 视口设置
-
-```cpp
-void onEnter() override {
-    Scene::onEnter();
-    
-    // 设置视口大小（影响坐标系）
-    setViewportSize(1280.0f, 720.0f);
-    
-    // 设置背景颜色
-    setBackgroundColor(Colors::Black);
-    
-    // 启用/禁用空间索引
-    setSpatialIndexingEnabled(true);
-}
-```
-
-### 空间索引
-
-```cpp
-// 获取空间管理器
-auto &spatialManager = getSpatialManager();
-
-// 切换空间索引策略
-spatialManager.setStrategy(SpatialStrategy::QuadTree);   // 四叉树
-spatialManager.setStrategy(SpatialStrategy::SpatialHash); // 空间哈希
-
-// 查询所有碰撞
-auto collisions = queryCollisions();
-```
-
-## 完整示例
-
-```cpp
-class GameScene : public Scene {
-public:
-    void onEnter() override {
-        Scene::onEnter();
-        
-        // 设置视口和背景
-        setViewportSize(1280.0f, 720.0f);
-        setBackgroundColor(Color(0.1f, 0.2f, 0.3f, 1.0f));
-        
-        // 启用空间索引
-        setSpatialIndexingEnabled(true);
-        
-        E2D_LOG_INFO("游戏场景已加载");
-    }
-    
-    void onUpdate(float dt) override {
-        Scene::onUpdate(dt);
-        
-        // 检查退出按键
-        auto &input = Application::instance().input();
-        if (input.isButtonPressed(SDL_CONTROLLER_BUTTON_START)) {
-            Application::instance().quit();
-        }
-    }
-    
-    void onRender(RenderBackend &renderer) override {
-        Scene::onRender(renderer);
-        
-        // 绘制 FPS
-        auto &app = Application::instance();
-        std::string fpsText = "FPS: " + std::to_string(app.fps());
-        // ...

-# Extra2D API 教程 - 04. 资源管理
-
-## 资源管理器
-
-Extra2D 使用资源管理器来统一加载和管理资源。
-
-### 获取资源管理器
-
-```cpp
-auto &resources = Application::instance().resources();
-```
-
-## 字体资源
-
-### 加载字体
-
-```cpp
-// 加载字体（路径，大小，使用后备字体）
-auto font = resources.loadFont("assets/font.ttf", 48, true);
-
-if (!font) {
-    E2D_LOG_ERROR("字体加载失败！");
-}
-```
-
-### 使用字体
-
-```cpp
-void onRender(RenderBackend &renderer) override {
-    if (font) {
-        renderer.drawText(*font, "Hello World", Vec2(100.0f, 100.0f), 
-                         Colors::White);
-    }
-}
-```
-
-## 纹理资源
-
-### 加载纹理
-
-```cpp
-// 加载纹理
-auto texture = resources.loadTexture("assets/player.png");
-
-if (!texture) {
-    E2D_LOG_ERROR("纹理加载失败！");
-}
-```
-
-### 创建精灵
-
-```cpp
-auto sprite = Sprite::create(texture);
-sprite->setPosition(Vec2(640.0f, 360.0f));
-addChild(sprite);
-```
-
-## 音效资源
-
-### 加载音效
-
-```cpp
-// 加载音效
-auto sound = resources.loadSound("assets/jump.wav");
-
-// 播放音效
-sound->play();
-
-// 循环播放
-sound->play(true);
-
-// 停止播放
-sound->stop();
-```
-
-## 资源路径解析
-
-Extra2D 的资源管理器支持多平台路径解析：
-
-### 路径优先级
-
-1. **原始路径**: `assets/font.ttf`
-2. **romfs 路径**: `romfs:/assets/font.ttf` (Switch)
-3. **sdmc 路径**: `sdmc:/assets/font.ttf` (Switch SD卡)
-4. **可执行文件相对路径** (Windows)
-
-### 使用示例
-
-```cpp
-// 所有平台使用相同的路径
-auto font = resources.loadFont("assets/font.ttf", 48, true);
-auto texture = resources.loadTexture("assets/images/player.png");
-auto sound = resources.loadSound("assets/audio/jump.wav");
-```

-## 注意事项
-
-### 必须调用 Scene::onEnter()
-
-```cpp
-void onEnter() override {
-    Scene::onEnter();  // 必须调用！
-    
-    // 否则子节点无法注册到空间索引
-    setSpatialIndexingEnabled(true);
-}
-```
-
-### 必须实现 getBoundingBox()
-
-```cpp
-class MyNode : public Node {
-public:
-    MyNode() {
-        setSpatialIndexed(true);
-    }
-    
-    // 必须实现！
-    Rect getBoundingBox() const override {
-        Vec2 pos = getPosition();
-        return Rect(pos.x - width_/2, pos.y - height_/2, width_, height_);
-    }
-};

-## 按钮 (Button)
-
-Extra2D 提供 Button 组件用于创建交互式按钮。
-
-### 创建按钮
-
-```cpp
-// 创建按钮
-auto button = Button::create();
-
-// 设置位置
-button->setPosition(Vec2(640.0f, 360.0f));
-
-// 设置锚点（中心）
-button->setAnchor(0.5f, 0.5f);
-
-// 添加到场景
-addChild(button);
-```
-
-### 设置按钮文本
-
-```cpp
-// 加载字体
-auto font = resources.loadFont("assets/font.ttf", 28, true);
-
-// 设置按钮字体和文本
-button->setFont(font);
-button->setText("点击我");
-button->setTextColor(Colors::Black);
-```
-
-### 设置按钮样式
-
-```cpp
-// 设置背景颜色（普通、悬停、按下）
-button->setBackgroundColor(
-    Colors::White,      // 普通状态
-    Colors::LightGray,  // 悬停状态
-    Colors::Gray        // 按下状态
-);
-
-// 设置边框
-button->setBorder(Colors::Black, 2.0f);
-
-// 设置内边距
-button->setPadding(Vec2(20.0f, 10.0f));
-
-// 设置固定大小
-button->setCustomSize(200.0f, 50.0f);
-```
-
-### 透明按钮
-
-```cpp
-// 创建透明按钮（仅文本可点击）
-auto button = Button::create();
-button->setFont(font);
-button->setText("菜单项");
-button->setTextColor(Colors::Black);
-
-// 透明背景
-button->setBackgroundColor(
-    Colors::Transparent,
-    Colors::Transparent,
-    Colors::Transparent
-);
-
-// 无边框
-button->setBorder(Colors::Transparent, 0.0f);
-
-// 无内边距
-button->setPadding(Vec2(0.0f, 0.0f));
-```

-    
-    if (font_) {
-        // 绘制文字
-        renderer.drawText(*font_, "Hello World", 
-                         Vec2(100.0f, 100.0f), Colors::White);
-        
-        // 绘制带颜色的文字
-        renderer.drawText(*font_, "红色文字", 
-                         Vec2(100.0f, 150.0f), Colors::Red);
-    }
-}
-```
-
-### 格式化文字
-
-```cpp
-void onRender(RenderBackend &renderer) override {
-    Scene::onRender(renderer);
-    
-    if (infoFont_) {
-        auto &app = Application::instance();
-        
-        // 绘制 FPS
-        std::stringstream ss;
-        ss << "FPS: " << app.fps();
-        renderer.drawText(*infoFont_, ss.str(), 
-                         Vec2(50.0f, 50.0f), Colors::Yellow);
-        
-        // 绘制节点数量
-        ss.str("");
-        ss << "Nodes: " << nodes_.size();
-        renderer.drawText(*infoFont_, ss.str(),

-## 音频系统概述
-
-Extra2D 使用 SDL2_mixer 作为音频后端，支持 WAV、MP3、OGG 等格式。
-
-## 音效播放
-
-### 加载和播放音效
-
-```cpp
-// 获取资源管理器
-auto &resources = Application::instance().resources();
-
-// 加载音效
-auto jumpSound = resources.loadSound("assets/jump.wav");
-auto attackSound = resources::loadSound("assets/attack.ogg");
-
-// 播放音效（一次）
-jumpSound->play();
-
-// 循环播放
-backgroundMusic->play(true);
-
-// 停止播放
-jumpSound->stop();
-```
-
-## 音频控制器
-
-### 创建音频控制器节点
-
-```cpp
-class AudioController : public Node {

-## 音频格式支持
-
-| 格式 | 支持 |
-|------|------|
-| WAV | ✓ |
-| MP3 | ✓ |
-| OGG | ✓ |
-| FLAC | ✓ |
-| MOD | ✓ |
-
-## 音量控制
-
-```cpp
-// 设置音效音量 (0-128)
-Mix_Volume(-1, MIX_MAX_VOLUME / 2);  // 所有音效
-Mix_Volume(channel, volume);          // 指定通道
-
-// 设置音乐音量 (0-128)
-Mix_VolumeMusic(volume);
-```
-
-## 最佳实践
-
-1. **预加载音效**: 在 `onEnter()` 中加载所有需要的音效
-2. **使用音频控制器**: 统一管理音效，方便控制开关
-3. **音效开关**: 提供用户选项控制音效开关
-4. **资源释放**: 音效资源会自动管理，无需手动释放
-
-## 总结
-
-Extra2D 的音频系统简单易用：
-
-```cpp
-// 加载
-auto sound = resources.loadSound("assets/sound.wav");
-
-// 播放
-sound->play();      // 一次
-sound->play(true);  // 循环
-
-// 停止
-sound->stop();
-```

-    -- MinGW 平台配置
-end
-```
-
-### Switch 平台配置
-- 设置平台: `set_plat("switch")`
-- 设置架构: `set_arch("arm64")`
-- 设置工具链: `set_toolchains("switch")`
-- 设置输出目录: `set_targetdir("../../build/examples/xxx")`

-
-## 构建命令
-
-### 配置项目
-
-```bash
-# 默认配置 (MinGW)
-xmake f -c
-
-# 指定平台 (使用 -p 参数)
-xmake f -c -p mingw
-xmake f -c -p switch
-
-# 指定 MinGW 路径（如果不在默认位置）
-xmake f -c -p mingw --mingw=C:\mingw
-
-# 禁用示例
-xmake f --examples=n
-
-# 启用调试日志
-xmake f --debug_logs=y
-```
-
-### 安装依赖 (MinGW)
-```bash
-xmake require -y
-```
-
-### 构建项目
-```bash
-# 构建所有目标
-xmake
-
-# 构建特定目标
-xmake -r extra2d
-xmake -r push_box
-
-# 并行构建
-xmake -j4
-```
-
-### 运行程序
-```bash
-# 运行示例
-xmake run push_box
-xmake run hello_world
-```
-
-### 清理构建
-```bash
-xmake clean
-xmake f -c  # 重新配置
-```
-
-## 输出目录结构
-
-```
-build/
-├── examples/
-│   ├── hello_world/
-│   │   ├── hello_world.exe    # MinGW
-│   │   ├── hello_world.nro    # Switch
-│   │   └── assets/            # 资源文件
-│   ├── push_box/
-│   ├── collision_demo/
-│   └── spatial_index_demo/
-└── ...
-```
-
-## 关键设计决策
-
-### 1. 平台检测
-- 使用 `is_plat()` 而不是手动检测，确保与主项目一致
-- 示例脚本继承主项目的平台配置
-
-### 2. 资源处理
-- **Switch**: 使用 romfs 嵌入 NRO 文件
-- **MinGW**: 构建后复制到输出目录
-
-### 3. 依赖管理
-- **MinGW**: 使用 Xmake 包管理器 (`add_requires`)
-- **Switch**: 使用 devkitPro 提供的库
-
-### 4. 工具链隔离
-- Switch 工具链定义在单独文件中
-- 通过 `set_toolchains("switch")` 切换
-
-## 常见问题
-
-### 1. 依赖包找不到
-```bash
-xmake repo -u
-xmake require -y
-```
-
-### 2. Switch 工具链找不到
-- 确保 DEVKITPRO 环境变量设置正确
-- 默认路径: `C:/devkitPro`
-
-### 3. 平台配置不匹配
-- 使用 `xmake show` 查看当前配置
-- 使用 `xmake f -c` 重新配置
-
-### 4. MinGW 路径问题
-如果 MinGW 安装在非默认位置，使用 `--mingw` 参数指定：
-```bash
-xmake f -c -p mingw --mingw=D:\Tools\mingw64
-```
-
-### 5. Switch 库找不到
-确保在 MSYS2 中安装了必要的库：
-```bash
-pacman -S switch-sdl2 switch-sdl2_mixer switch-glm
-```
-
-## 扩展指南
-
-### 添加新示例
-1. 在 `examples/` 下创建新目录
-2. 创建 `xmake.lua` 构建脚本
-3. 在 `xmake.lua` 中添加 `includes("examples/new_example")`
-
-### 添加新平台
-1. 在 `xmake/toolchains/` 下创建工具链定义
-2. 在 `xmake.lua` 中添加平台检测逻辑
-3. 在 `xmake/engine.lua` 中添加平台配置
