1.敌人方实现

{
public int EnemySpeed { get; internal set; }
public int EnemyAttackDistance { get; internal set; }
public int EnemyChaseDistance { get; internal set; }

{
GameObject enemy = null;
switch (type)
{
case 1:
enemy = Instantiate(slowEnemyPrefab, position, Quaternion.identity);
enemy.tag = "SlowEnemy";
// enemy.AddComponent<EnemyBasics>();
enemy.GetComponent<EnemyBasics>().EnemySpeed = 1;
enemy.GetComponent<EnemyBasics>().EnemyAttackDistance = 1;
enemy.GetComponent<EnemyBasics>().EnemyChaseDistance = 8;
break;
case 2:

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);
}
}
}
}
挂载
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;
}
}
