2.我方实现

玩家控制代码

using UnityEngine;

public class PlayerController : MonoBehaviour
{
    float CD = 2;
    [SerializeField] private GameObject BombPre;
    void Update()
    {
        //获取水平虚拟轴
        float horizontal = Input.GetAxis("Horizontal");
        //获取垂直虚拟轴
        float vertical = Input.GetAxis("Vertical");
        //创建一个向量，该向量为用户按下按键对应的向量
        //这里让horizontal控制x轴移动，vertical控制z轴移动
        Vector3 dir = new Vector3(vertical,  0, -horizontal);

        //如果向量不为0，证明玩家一定按了方向键
        if (dir != Vector3.zero)
        {
            //玩家转向dir向量的方向
            transform.rotation = Quaternion.LookRotation(dir);
            //Update是按帧刷新的，如果参数不乘以Time.deltaTime,代表的含义为每帧移动2m
            //所以这里做一个转换，让2乘以帧时间间隔Time.deltaTi//即可转换单位，从每帧移动2m变为每秒移动2m
            //转换单位还可以同步不同设备的速度,
            //因为不同的设备可能有不同的帧率，所以如果不转换单位
            //那么可能看到不同设备下的移动速度是不同的
            transform.Translate(Vector3.forward * 7 * Time.deltaTime);
        }
        CD += Time.deltaTime;
        //如果按下U键
        if (Input.GetKeyDown(KeyCode.U))
        {
            Debug.Log("检测到玩家按下U键，放下炸弹");
            //2s的CD
            if (CD > 0.2f)
            {
                //重置CD
                CD = 0;
                //释放炸弹
                Instantiate(BombPre, transform.position, transform.rotation);
            }
        }
    }
}

摄像机代码（或者直接把摄像机变成玩家的子物体，就不用写代码了）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraControllerr : MonoBehaviour
{
    //保存向量
    private Vector3 vecter3;
    private Transform player;
    
    void Start()
    {
        //两种方法找Player
       // player = GameObject.Find("Player").transform;
        player = GameObject.FindGameObjectWithTag("Player").transform;
        vecter3 =player.transform.position-transform.position;
    }

    // Update is called once per frame
    void Update()
    {
        transform.position = player.transform.position - vecter3;
    }
}
