## 初始化命令示例

### 创建 2D 平台游戏项目

```
创建一个 2D 平台游戏项目结构：
- 项目名称：ForestAdventure
- 特性：
  - 玩家控制器（状态机）
  - 敌人系统
  - 存档系统
  - 音频管理
  - UI 系统
```

### AI 执行步骤

1. 创建目录结构
2. 生成 project.godot
3. 生成核心 autoload 脚本
4. 生成玩家场景和脚本
5. 生成 UI 场景
6. 生成配置文件骨架
7. 创建 README.md

---

## 验证检查清单

项目结构生成后验证：

- [ ] project.godot 配置正确
- [ ] 所有 autoload 路径存在
- [ ] 主场景可以运行
- [ ] 物理层级配置正确
- [ ] 输入映射已设置
- [ ] 目录结构符合规范
- [ ] .gitignore 已配置
