EnemyAnimation组件已经启用并且挂载在enemy上，32节的EnemyMove寻路也已经挂载，但是enemy无法自动巡逻，游戏开始后观察发现enemy的NavMsehAgent组件开始巡逻，而游戏模型并没有反应。

EnemyMove的代码如下

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

public class EnemyMove : MonoBehaviour
{

    public Transform[] wayPoints;
    public float patrolTime = 3f;
    
    private float patrolTimer = 2;
    private int index = 0;
    private NavMeshAgent navAgent;

    void Awake()
    {
        navAgent = this.GetComponent<NavMeshAgent>();
        navAgent.destination = wayPoints[index].position;
        navAgent.updatePosition = false;
        navAgent.updateRotation = false;
    }

	void Update () {
		Patrolling();
	}

    private void Patrolling()
    {
        if (navAgent.remainingDistance < 0.5f)
        {
            patrolTimer += Time.deltaTime;
            if (patrolTimer > patrolTime)
            {
                index++;
                index %= 4;
                navAgent.destination = wayPoints[index].position;
                navAgent.updatePosition = false;
                navAgent.updateRotation = false;
                patrolTimer = 0;
            }
        }
    }
}

U3D设置如下
