// 文件：MonsterContral.cs
// 职责：鱼（怪物）实体基类 —— 状态机、路径移动、动画、死亡处理
// 优化点：
//   1. 方向朝向逻辑提取为独立方法 ApplyFacingDirection，消除大量重复 switch
//   2. OnMoveUpdata 按 isyz 分支，各分支内复用 ApplyFacingDirection
//   3. OnDestroy 统一清理三个字典，去除重复判断
//   4. 常量命名使用 PascalCase，符合 C# 规范
//   5. 补充 XML 注释，明确方法职责
//   6. forwordXYZ 空检查改用 string.IsNullOrEmpty
