🎶前言

🅰️

🎶（A）常用关键API

🎶（B）需求分析

🎶（C）行为实现——小地图和相机跟随

• Target Texture 行为渲染

//___________项目:     
//___________功能：     地图相机跟随

public class cameraFollow : MonoBehaviour
{
    public Transform  Tank;
    private Vector3 offset;
    public float heiht;
    private float OffX;
    private float offZ;

    private void Start()
    {
        heiht = transform.position.y; 
    
    }
    private void LateUpdate()    //注意点1：相机相关逻辑存放点
    {
        if (Tank == null) return; //注意点2：为空判断

        //只有相机的Z轴和X轴跟着Tank变化，y则是距离地面的高度
        offset.x  = Tank.position.x;
        offset.z  = Tank.position.z;
        offset.y = heiht;
        gameObject.transform.position = offset;

       
    }
}

🎶（D）行为实现——捡起武器发射炮弹

😶‍🌫️ 步骤：

1.靠近武器，碰撞检测
2.将武器位置于坦克发射位置重合
3.武器中封装了发射方法
4.发射方法中封装了炮弹实例化并且发射的逻辑

坦克基类的封装

public abstract  class TankFather : MonoBehaviour
{
    //攻击和防御相关
    public int attack;
    public int defence; 
    public int nowBlood;
    public int maxBlood;
    //移动和转速相关
    public int moveSpeed;
    public int RotateSpeed;
    public int HeadSpeed;
    public Transform  Head;
    //击败特效
    public GameObject diedEffect;
  

    //受伤行为
    public virtual  void Heart(TankFather other)
    {
        //当攻击力大于防御力时才生效
        if (other.attack - defence > 0)
        {
            nowBlood -= (other.attack - defence);
        }
        if(nowBlood <= 0 )
        {
            nowBlood = 0;
            Death();
        }
       //更新血条
        GamePlane.SingleInstance.UpdataBlood(maxBlood ,nowBlood );
    }

    //死亡行为
    public virtual  void Death()
    {
        Destroy(this);
        //将特效实例化相关逻辑
        GameObject effect = Instantiate(diedEffect, this.transform.position ,this.transform.rotation);
        AudioSource soudClip = GetComponent<AudioSource>();
        soudClip.enabled  = MusicContol.SingleMusicContol.nowMusicData.soundSwitch;
        soudClip.volume = MusicContol.SingleMusicContol.nowMusicData.soundRoll ;
        soudClip.mute = false;
        soudClip.playOnAwake = true;
    }

    //开火行为
    public abstract void Fire();  //子类中每一个的开火方式都不同，作为抽象方法
    
   
}

        //头部炮管的旋转 = 大小*轴向
        Head.Rotate(Input.GetAxis ("Mouse X") *Vector3.up*HeadSpeed*Time .deltaTime );
        //左键发射炮弹
        if(Input.GetMouseButtonDown(0))
        {
            Fire();

        }
    }

   

    //捡武器行为
    public void ChangeWeapon(GameObject weapon)

    }

    //开火行为重写

            Rigidbody shootBall = ball.GetComponent<Rigidbody>();

            shootBall.AddForce(transform.forward * bulletSpeed);

            movScript.Tank = Tank;  //声明子弹是由谁打出去的
        }     
    }

    //如果碰到标签是主坦克玩家 并且 武器没有主人
    private void OnCollisionEnter(Collision collision)
    {
        
        if (Tank == null && collision.transform.name  == "Player")
        {
            Tank = collision.gameObject;
            MainTank player = collision.gameObject.GetComponent<MainTank>();

public class BulletMove : MonoBehaviour

    private float endTime = 15f; //销毁倒计时

    private void Start()
    {
       
    }
    //子弹的销毁及特效
    private void OnTriggerEnter(Collider other)

        {
            if (DeidEffect != null)
            {
                GameObject eff =  Instantiate(DeidEffect, transform.position, transform.rotation);
                //音效控制
                distorySound = eff.GetComponent<AudioSource>();
                distorySound.enabled = MusicContol.SingleMusicContol.nowMusicData.soundSwitch;
                distorySound.volume = MusicContol.SingleMusicContol.nowMusicData.soundRoll;
                eff.AddComponent<SelfDestroy>();
            }
            Destroy(this.gameObject);          
        }    
    }
    
    private void Update()
    {
        //当未碰撞时自动销毁
        endTimeDistory(gameObject);
        
    }

    //倒计时销毁
    public void endTimeDistory( GameObject instans)
    {
        endTime = Mathf.MoveTowards(endTime, 0, 0.1f);
        if (endTime <= 0) Destroy(instans);
    }
}

总结：

问题： 为什么炮弹生成了却无法射出 ; 原因: FreezePosition被锁定了

问题：往前走时，发射方向和炮口方向相反
