本文详细介绍了在Unity3D中如何创建并实现一个智能巡逻兵的AI行为，包括路径规划、敌人检测和行为状态切换等关键点。

首先还是得熟悉一下uml图，基本上和前面的游戏差不多，主要就是加了事件的订阅和发布

首先是Director类和两个接口，和之前的差不多，主要就是调整一下接口的函数，从上面的UML图可以看出，IUserAction的函数主要就是用于GUI中以便调用

public interface ISceneControl
{
    void LoadResources();
}

public interface IUserAction
{
    void playerMoving(float x, float z);
    bool getState();
    void setState(bool state);
}

public class Director : System.Object
{

    public ISceneControl currentSceneController { get; set; }

    private static Director director;

    private Director()
    {
        
    }

    public static Director getInstance()
    {
        if (director == null)
        {
            director = new Director();
        }
        return director;
    }
}

下面就是IUserGUI类，主要用于渲染出一个界面，在游戏开始结束时进行显示信息，和用于开始游戏等操作

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

public class IUserGUI : MonoBehaviour {

    private IUserAction act;
	// Use this for initialization
	void Start () {
        act = Director.getInstance().currentSceneController as IUserAction;
	}
	
	// Update is called once per frame
	void Update () {
        if(!act.getState())
        {
            float x = Input.GetAxis("Horizontal");
            float z = Input.GetAxis("Vertical");
            act.playerMoving(x, z);
        }
    }
    void OnGUI()
    {
        if(act.getState())
        {
            GUI.Label(new Rect(Screen.width / 2 - 100, Screen.height / 2 - 200, 400, 400), "GAMEOVER" + " your score is " + Singleton<ScoreRecorder>.Instance.score.ToString());
            if (GUI.Button(new Rect(Screen.width / 2 - 45, Screen.height / 2 - 45, 90, 90), "Restart"))
            {
                act.setState(false);
                Singleton<ScoreRecorder>.Instance.Reset();
            }
        }
        else
        {
            GUI.Label(new Rect(2 * Screen.width / 3, 0, 400, 400), "score: " + Singleton<ScoreRecorder>.Instance.score.ToString());
        }
    }
}

下面就是工厂模式的一些类，PlayerData是添加到player上的组件，用来纪录用户在地图的那个方块。然后PatrolData就是挂在Patrol上的组件，纪录了patrol在那个地区巡逻，和是不是在追击用户，还有originPos就是追击动作之前的位置，方便回去继续巡逻。工厂类就是用来生成patrol和回收的，和之前的飞碟和射箭差不多。

public class PlayerData : MonoBehaviour
{
    public int areaIndex;
}

public class PatrolData : MonoBehaviour
{
    public int currentIndex;
    public bool isFollow = false;
    public GameObject player; 
    public Vector3 originPos;
}

public class PatrolFactory : MonoBehaviour {

    private GameObject firstPatrol = null;
    private List<PatrolData> used = new List<PatrolData>();
    private List<PatrolData> free = new List<PatrolData>();

    private void Awake()
    {
        firstPatrol = GameObject.Instantiate<GameObject>(Resources.Load<GameObject>("prefab/patrol"), Vector3.zero, Quaternion.identity);
        firstPatrol.SetActive(false);
    }

    public GameObject GetPatrol()
    {
        GameObject newPatrol = null;
        if (free.Count > 0)
        {
            newPatrol = free[0].gameObject;
            free.Remove(free[0]);
        }
        else
        {
            newPatrol = GameObject.Instantiate<GameObject>(firstPatrol, Vector3.zero, Quaternion.identity);
            newPatrol.AddComponent<PatrolData>();
        }

        used.Add(newPatrol.GetComponent<PatrolData>());
        newPatrol.name = newPatrol.GetInstanceID().ToString();

        return newPatrol;
    }

    public void FreePatrol(Game
