前言
️
（A）UML
（B）需求分析
（C）行为实现——炮台的自动检测并攻击
️：步骤实现
1.炮台的行为逻辑封装：旋转，触发检测，发射炮弹及特效
2.检测玩家后自动瞄准攻击
3.玩家扣血，更新血条，触发保护罩特效及死亡

（D）行为实现——敌军坦克的移动路线和检测攻击
️：步骤实现
- 1.指定移动位置，设置朝向
- 2.行为逻辑封装。开火，受伤
- 3.自动检测闯入者

}
}
问题：
1.受到伤害，开启了保护罩但是不扣血
2.敌方坦克，原地打转，未按规定路线移动
解决：
1.子弹检测逻辑错误
2.位置空点绑定在对象身上变成了子对象因此无法达到效果
总结：
- 1.检测触发的方式：①触发器检测②向量距离检测
- 2.多点指定移动，加入向量距离判断，重合的机率小，故此不能 A物体距离 == B物体距离
- 3.子坦克继承了父类脚本，引用传递时直接用父类即可获得该子类，（原因父类名字相同，但是子类名字不同，无法确定，所以里氏替换作用在此体现）
