我有以下代碼：using UnityEngine;using UnityEngine.AI;using System.Collections;public class AutoPilot : MonoBehaviour {public Transform[] points;private int destPoint = 0;private NavMeshAgent agent;void Start () {    agent = GetComponent<NavMeshAgent>();    // Disabling auto-braking allows for continuous movement    // between points (ie, the agent doesn't slow down as it    // approaches a destination point).    GotoNextPoint();}void GotoNextPoint() {    // Returns if no points have been set up    if (points.Length == 0)        return;    // Set the agent to go to the currently selected destination.    agent.destination = points[destPoint].transform.position;    // Choose the next point in the array as the destination,    // cycling to the start if necessary.    destPoint = (destPoint + 1) % points.Length;}void Update () {    // Choose the next destination point when the agent gets    // close to the current one.    if (!agent.pathPending && agent.remainingDistance < 2f)        GotoNextPoint();}}我經過航路點的地方，代理跟蹤它們，但是當我到達最后一個航路點時，如何使它重新啟動？繼續前進？可以通過某種方式重置還是最好的方法是什么？
