**问题背景**
原项目全部逻辑集中在 main.cpp（1468 行），大量全局变量、4 方向逻辑
复制粘贴 4 遍、场景通过递归函数调用跳转（栈溢出隐患），难以维护扩展。
**重构内容**
文件架构（新增 src/ 目录）:
- src/Game.h/.cpp — 状态机驱动主循环，Scene 枚举消除递归跳转
- src/AssetManager.h/.cpp — 纹理/字体/BGM 加载与缓存管理
- src/Renderer.h/.cpp — SDL 渲染封装（清屏/纹理/文字/提交）
- src/Map.h/.cpp — 地图数据 + 统一碰撞检测
- src/Tank.h/.cpp — 坦克类，dx()/dy() 方向向量消除 4x 复制粘贴
- src/Bullet.h/.cpp — 子弹类，peekAt()/step() 封装移动逻辑
- src/UI.h — 按钮区域常量 + 命中检测
核心改进:
- 全局变量清零 → 全部归入 Game 类实例管理
- 场景递归跳转 → Scene 枚举状态机，主循环驱动
- 4 方向复制粘贴 → 方向向量 {dx,dy} 表统一处理
- 修复 EnemiesMove 中循环变量 i 遮蔽 bug
- clock() → SDL_GetTicks()，跨平台时间精度
- 清理死代码 map1[50]、旧注释、未使用常量
- data_config.h 精简为纯常量
文件变更:
- 新增 7 个源文件（src/下）
- 重写 main.cpp（1468 → 6 行入口）
- 重写 data_config.h、CMakeLists.txt
- 删除 tank.h、bullet.h、map.h、map.cpp（被新架构替代）
- 更新 .gitignore（build_Debug/、.hermes/ 等）
