技术难点：由于是第三人称射击游戏，角色和相机之间有夹角，所以枪口点和准星是有误差的，下面是和平精英手游截图，我用AK射击zhuzi

 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class CameraFollow : MonoBehaviour
{public Transform ShootPoint;//射击距离(米)public float AimDistance = 100;public float CamToAimDis = 103;private Vector3 AimPoint;//横向观察夹角public float HorizonAngle = 0.5f;public float VerticalAngle;//旋转轴向public Vector3 axis = new Vector3(0, 1, 0);void Update(){//射击方向的平面方向Vector3 dir = ShootPoint.forward;//计算射击目标点AimPoint = ShootPoint.position + ShootPoint.forward * AimDistance;Vector3 camDir = Quaternion.AngleAxis(HorizonAngle, axis) * dir;Vector3 CamPos =  AimPoint - Quaternion.AngleAxis(HorizonAngle, axis) * dir * CamToAimDis;transform.position = CamPos;transform.forward = camDir;}}
