向量3.向不工作方向移动。它不会移动或显示任何错误

您需要更好地将状态转换逻辑与状态活动逻辑分开。当状态转换发生在同一块中时,应该运行的代码与状态处于活动状态时,应该在每一帧中运行的代码相同。

处理这个问题的一种方法是将状态转换为协同过程:

public class PlaneAI : MonoBehaviour
{
    public Transform[] runwayPoints;
    public Transform[] startTakeoffPoints;
    public Transform[] takeoffPoints;
    public NavMeshAgent navMeshAgent;
    public bool takeoff = false;
    bool departing = false;
    bool moving = false;
    int selectedRunway;

    LineRenderer lr;

    void Awake()
    { 
        lr = GetComponent<LineRenderer>();
    }

    IEnumerator Depart()
    {
        navMeshAgent.SetDestination(runwayPoints[selectedRunway = Random.Range(0, 
                runwayPoints.Length)].position);
        yield return new WaitForSeconds(3f);

        departing = true;
        while(departing)
        {           
            if (navMeshAgent.pathStatus == NavMeshPathStatus.PathComplete 
                    && navMeshAgent.remainingDistance == 0)
            {
                StartCoroutine(MoveTakeoff());
                yield break;
            }
            yield return null;
        }
    }

    IEnumerator MoveTakeOff()
    {
        departing = false;
        moving = true;

        navMeshAgent.enabled = false;
        GetComponent<Collider>().enabled = false;
        transform.LookAt(new Vector3(takeoffPoints[selectedRunway].position.x, 0,
                takeoffPoints[selectedRunway].position.z));

        while (moving)
        {
            if (Vector3.Distance(transform.position, 
                    startTakeoffPoints[selectedRunway].position) <= 0.001f)
            {                    
                StartCoroutine(TakeOff())
                yield return break;
            }

            transform.position = Vector3.MoveTowards(transform.position, 
                    startTakeoffPoints[selectedRunway].position, 2);

            yield return null;
        }
    }

    IEnumerator Takeoff()
    {
        moving = false;
        takeOff = true;

        transform.LookAt(takeoffPoints[selectedRunway]);

        while (takeOff)
        {
 
            if (Vector3.Distance(transform.position, 
                    startTakeoffPoints[selectedRunway].position) <= 0.001f)
            {
                takeoff = false;
                yield break;
            }

            transform.position = Vector3.MoveTowards(transform.position, 
                    takeoffPoints[selectedRunway].position, 3); 
            yield return null;
        }
    }

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.P))
        {
            StopAllCoroutines();
            StartCoroutine(Depart());
        }

        lr.SetPosition(0, new Vector3(transform.position.x, 1, transform.position.z));
        lr.SetPosition(1, navMeshAgent.destination);

    }
}

理想情况下,状态应该是一个单一的枚举数,而不是几个布尔数,但这很有希望显示出我的意思。
