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;
    }


}
