把摄像机放在人物GameObject里面，位置设置在一个合适的位置，前后左右移动，就都会带者摄像机移动了在脚本中得到摄像机，并获取鼠标x,y轴的偏移量鼠标x轴的偏移量，直接用来旋转人物的y轴，这样带者摄像机也会旋转鼠标y轴的偏移量，用来让相机绕着人物的x轴旋转
代码实现：
using System;using System.Collections;using System.Collections.Generic;using UnityEngine;public class PlayerMove : MonoBehaviour{private Camera mCamera;// Start is called before the first frame updatevoid Start(){mCamera = transform.Find("PlayerCamera").GetComponent<Camera>();}// Update is called once per framevoid Update(){float x = Input.GetAxisRaw("Mouse X");float y = Input.GetAxisRaw("Mouse Y");//鼠标x轴的偏移量，直接用来旋转人物的y轴transform.Rotate(new Vector3(0, x, 0), Space.Self);//鼠标y轴的偏移量，用来让相机绕着人物的x轴旋转 mCamera.transform.RotateAround(transform.position,transform.right,-y);}}
