一、导入插件Cinemachine

重命名为ThirdPersonCamera

Follow和LookAt 选择为player

镜像Y轴，取消X轴

摄像机绑定模式为World Space

二、挂载代码PlayerController

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

public class PlayerControl : MonoBehaviour
{
    //记录轴向值
    private float InputH;
	private float InputV;
	private Vector3 Direction;//记录移动方向

	public CharacterController Controller1;
	//玩家速度
	public float MoveSpeed=10;
	//玩家相机
	public Camera Camera1;
	//计算旋转角度引用
	private float TurnSmooth;//旋转角度
	public float TurnTime = 0.1f;//旋转时长

	private void Start()
	{
		
	}
	private void Update()
	{
		Move();
	}

	/// <summary>
	/// 移动方法
	/// </summary>
	public void Move()
    {
		//获取水平和垂直
		InputH = Input.GetAxis("Horizontal");
		InputV = Input.GetAxis("Vertical");
		Direction = new Vector3(InputH, 0, InputV);

		if (Direction.magnitude>=0.1f)//检测是否有玩家输入
		{
			移动
			//Controller1.Move(Direction*MoveSpeed*Time.deltaTime);

			//计算目标角度
			float TargetAngle = Mathf.Atan2(Direction.x, Direction.z) * Mathf.Rad2Deg
				+ Camera1.transform.eulerAngles.y;//弧度值转为角度值
												  //平滑角度过渡
			float Angle = Mathf.SmoothDampAngle(this.transform.eulerAngles.y, TargetAngle,
				ref TurnSmooth, TurnTime);
			//设置角色旋转
			this.transform.rotation = Quaternion.Euler(0, Angle, 0);
			//计算新的移动方向
			
			Vector3 MoveDirection = Quaternion.Euler(0, TargetAngle, 0) * Vector3.forward;
			
			//移动角色
			Controller1.Move(MoveDirection * MoveSpeed * Time.deltaTime);
		}

		
	}
}
