why does the car teleport to my waypoints

问题

我制作了一段代码，允许汽车驶向预定的路标，如果它到达那里，它会自动驶向下一个。以下是代码部分：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class AICar : MonoBehaviour
{

public Transform Player;
public Transform Player2;
public Transform Player3;
public Transform Player4;
public Transform Player5;
public Transform Player6;
public int MoveSpeed = 5;
int MaxDist = 10;
int MinDist = 5;

void Start()
{
    StartCoroutine(SparseUpdate());
}

IEnumerator SparseUpdate()
{
    yield return new WaitForSeconds(0);
    while (true)
    {
        yield return null;

        transform.LookAt(Player);
        if (Vector3.Distance(transform.position, Player.position) >= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            Debug.Log(MoveSpeed);
            if (Vector3.Distance(transform.position, Player.position) <= MaxDist)
            {
                StartCoroutine(SparseUpdateSecond());
            }
            // 在此处执行您在 Update 中通常要执行的所有常规操作。
        }
    }
}

IEnumerator SparseUpdateSecond()
{
    yield return new WaitForSeconds(0);
    while (true)
    {
        yield return null;

        transform.LookAt(Player2);
        if (Vector3.Distance(transform.position, Player2.position) >= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            Debug.Log(MoveSpeed);
            if (Vector3.Distance(transform.position, Player.position) <= MaxDist)
            {
                StartCoroutine(SparseUpdateThird());
            }
            // 在此处执行您在 Update 中通常要执行的所有常规操作。
        }
    }
}

IEnumerator SparseUpdateThird()
{
    yield return azerobgerbdhzvidhqszckrsqirhzretrkev
    while (true)
    {
        yield return null;

        transform.LookAt(Player3);
        if (Vector3.Distance(transform.position, Player3.position) >= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            if (Vector3.Distance(transform.position, Player3.position) <= MaxDist)
            {
                StartCoroutine(SparseUpdateFourth());
            }
            // 在此处执行您在 Update 中通常要执行的所有常规操作。
        }
    }
}

IEnumerator SparseUpdateFourth()
{
    yield return new WaitForSeconds(0);
    while (true)
    {
        yield return null;

        transform.LookAt(Player4);
        if (Vector3.Distance(transform.position, Player4.position) >= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            if (Vector3.Distance(transform.position, Player4.position) <= MaxDist)
            {
                StartCoroutine(SparseUpdateFifth());
            }
            // 在此处执行您在 Update 中通常要执行的所有常规操作。
        }
    }
}

IEnumerator SparseUpdateFifth()
{
    yield return new WaitForSeconds(0);
    while (true)
    {
        yield return null;

        transform.LookAt(Player5);
        if (Vector3.Distance(transform.position, Player5.position) >= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            if (Vector3.Distance(transform.position, Player5.position) <= MaxDist)
            {
                StartCoroutine(SparseUpdateSixth());
            }
            // 在此处执行您在 Update 中通常要执行的所有常规操作。
        }
    }
}

IEnumerator SparseUpdateSixth()
{
    yield return new WaitForSeconds(0);
    while (true)
    {
        yield return null;

        transform.LookAt(Player6);
        if (Vector3.Distance(transform.position, Player6.position) >= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            if (Vector3.Distance(transform.position, Player6.position) <= MaxDist)
            {
                // 在此处执行您在 Update 中通常要执行的所有常规操作。
            }
        }
    }
}

}


它慢慢地驶向第一个路标，这是正确的，但对于其他路标，它非常快，我不知道为什么？有人可以帮助吗？谢谢。

我尝试了其他方法来移动汽车，但都没有成功。

I made a code that allows a car to drive to defined waypoints, if it arrives there it automaticly drives to the next. Following code:

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

    public Transform Player6;
    public int MoveSpeed = 5;
    int MaxDist = 10;
    int MinDist = 5;




    void Start()
  {
      StartCoroutine(SparseUpdate());
  }

  IEnumerator SparseUpdate()
  {
      yield return new WaitForSeconds(0);
      while(true)

          {
              transform.position += transform.forward * MoveSpeed * Time.deltaTime;
              Debug.Log(MoveSpeed);
              if (Vector3.Distance(transform.position, Player.position) &lt;= MaxDist)
              {
                  StartCoroutine(SparseUpdateSecond());
              }
          // Do all the normal things you&#39;d do in Update here instead.

            }
           }
        }




  }

it drives slowly to the first, which is right but to the others it is very quick and i dont know why? can anbyody help?
thank you

I tried other methods to move the car but nothing works

得分: 0

if (Vector3.Distance(transform.position, Player3.position) >= MinDist)
{
transform.position += transform.forward * MoveSpeed * Time.deltaTime;
if (Vector3.Distance(transform.position, Player3.position) <= MaxDist)
{
StartCoroutine(SparseUpdateFourth());
break;
}
// 在这里执行正常的 Update 操作。
}

英文:

As always, place debugger around to see how your code actually works do miracles!

In this one though, since each of your IEnumerator placed inside a while(true), it simply doesnt stop and ends up running all the IEnumerators at the same time.

In sort, just include a break; after each time you start new coroutine, something like this should do

if (Vector3.Distance(transform.position, Player3.position) &gt;= MinDist)
        {
            transform.position += transform.forward * MoveSpeed * Time.deltaTime;
            if (Vector3.Distance(transform.position, Player3.position) &lt;= MaxDist)
            {
              StartCoroutine(SparseUpdateFourth());
              break;
            }
        // Do all the normal things you&#39;d do in Update here instead.
