如果光線沒有碰到障礙物，只能看玩家

Question

我在這裏有一個迴避腳本，但我唯一的問題是，它總是試圖看着玩家，即使它繞過障礙導致它抖動。我想知道如果我的射線沒有碰到障礙物，而是讓它在同一時間向玩家移動，我只能看看玩家。任何幫助，將不勝感激， 目前與unity3D工作

using UnityEngine; 
using System.Collections; 

public class enemyAI : MonoBehaviour 
{ 
    public Transform target; 
    public float moveSpeed; 
    public float rotationSpeed; 
    public float minDistance = 0.5f; 
    public static enemyAI enemyAIself; 
    RaycastHit hit; 

    void Awake() 
    { 
     enemyAIself = this; 
    } 
    void Start() 
    { 
     GameObject goTo = GameObject.FindGameObjectWithTag("Player"); 
     target = goTo.transform; 
    } 

    void Update() 
    { 
     Vector3 dir = (target.position - transform.position).normalized; 
     if (Physics.Raycast(transform.position, transform.forward, out hit, 5.0f, (1<<8))) 
     { 
     Debug.DrawRay(transform.position, hit.point, Color.blue); 
     dir += hit.normal * 50; 
     } 

     Vector3 leftR = transform.position; 
     Vector3 rightR = transform.position; 

     leftR.x -= 2; 
     rightR.x += 2; 

     if (Physics.Raycast(leftR, transform.forward, out hit, 5.0f, (1<<8))) 
     { 
     Debug.DrawRay(leftR, hit.point, Color.blue); 
      dir += hit.normal * 50; 
     } 

     if (Physics.Raycast(rightR, transform.forward, 5.0f, (1<<8))) 
     { 
     Debug.DrawRay(rightR, hit.point, Color.blue); 
     dir += hit.normal * 50; 

     } 
     Quaternion rot = Quaternion.LookRotation(dir); 
     transform.rotation = Quaternion.Slerp(transform.rotation, rot, rotationSpeed * Time.deltaTime); 

     if (Vector3.SqrMagnitude(target.position - transform.position)> (minDistance * minDistance)) 
     { 
     //move towards the target 
     transform.position += transform.forward * moveSpeed * Time.deltaTime; 
     } 

    } 


}

爲了使它只能看玩家如果光線投射是不打的障礙，但使它走向球員移動的同時，你可能

在命中點創建臨時航點（的Vector3）沿障礙

移動的航點，直到從它的光線投射別打擊障礙

移動到這個航點

繼續走向玩家
