Unity实现人物平滑转身

using UnityEngine;
using System.Collections;
 
public class PlayerController : MonoBehaviour {
 float ver = 0;
 float hor = 0;
 public float turnspeed = 10;
 
 // Use this for initialization
 void Start () {
 
 }
 
 // Update is called once per frame
 void Update () {
 hor = Input.GetAxis("Horizontal");
 ver = Input.GetAxis("Vertical");
 
 }
 void Rotating (float hor, float ver)
 {
 //获取方向
 Vector3 dir = new Vector3 (hor,0,ver);
 //将方向转换为四元数
 Quaternion quaDir = Quaternion.LookRotation(dir,Vector3.up);
 //缓慢转动到目标点
 transform.rotation = Quaternion.Lerp(transform.rotation,quaDir,Time.fixedDeltaTime*turnspeed);
 
 
 
 }
 
 void FixedUpdate(){
 
 
 if(hor!= 0 ||ver!= 0 ){
  //转身
  Rotating(hor,ver);
  
 
  }
 }
 
}
