🎶（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

public class EnemyTank:TankFather 
{//随机移动点的位置数组public  Transform[] randomPosition;//目标位置private Transform target;//目标坦克public Transform Player;//检测范围public float distance = 10f;public AudioSource shootMusic;   //发射音效public GameObject shootball;     //发射的子弹类型public float shootSpeed = 1000f; //子弹的速度 public Transform[] shootTransform; //发射的组件信息public bool shootSwitch = false;  private float endTime = 3f;      //子弹发射间隔的时间private void Start(){//属性初始化赋值maxBlood = 500;nowBlood = 500;attack = 30;HeadSpeed = 50;//射击音效关闭shootMusic.enabled = false;moveSpeed = 10f;//先随机整一个目标点RandomPosition();}private void Update(){    transform.LookAt(target);//始终超自己的正方向移动transform.Translate(Vector3.forward * moveSpeed * Time.deltaTime);  //当距离差不多相等时，再随机目标点if(Vector3.Distance(transform .position ,target .position)< 0.5f){RandomPosition();}//范围检测if (Vector3 .Distance(transform .position ,Player.position )<= distance && Player !=null ){//炮口瞄准玩家Head.transform.LookAt(Player);//倒计时发射子弹endTime = Mathf.MoveTowards(endTime, 0, 0.1f);if (endTime <= 0){Fire();endTime = 3f;}        }}//随机指向一个移动点public void RandomPosition(){if (randomPosition.Length != 0)target = randomPosition[Random.Range(0, randomPosition.Length)];}//触发检测private void OnTriggerEnter(Collider other){if (other.gameObject.tag == "bullet" ){//添加子弹挂载的目标坦克，方便获取该子弹的攻击力，与受伤逻辑相结合BulletMove ball = other.gameObject.GetComponent<BulletMove>();TankFather ballTank = ball.Tank.GetComponent<TankFather>();//当子弹不是自己打的到自己身上的时候if (ballTank.tag != gameObject.tag){//扣血Heart(ballTank);}}}public override void Fire(){//开启射击音效shootMusic.enabled = true;shootMusic.Play();for (int i = 0; i < shootTransform.Length ; i++){GameObject ball = Instantiate(shootball, shootTransform[i].position, shootTransform[i].rotation);BulletMove movScript = ball.GetComponent<BulletMove>();Rigidbody shootBall = ball.GetComponent<Rigidbody>();shootBall.AddForce(shootTransform[i].transform.forward * shootSpeed);movScript.Tank = gameObject;  //声明子弹是由谁打出去的}}}

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）
