why does the car teleport to my waypoints

问题

  1. 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

  1. public Transform Player;
  2. public Transform Player2;

  6. public Transform Player6;
  7. public int MoveSpeed = 5;
  8. int MaxDist = 10;
  9. int MinDist = 5;
  11. void Start()
  12. {
  13.     StartCoroutine(SparseUpdate());
  14. }
  16. IEnumerator SparseUpdate()
  17. {
  18.     yield return new WaitForSeconds(0);
  19.     while (true)
  20.     {
  21.         yield return null;
  23.         transform.LookAt(Player);
  24.         if (Vector3.Distance(transform.position, Player.position) >= MinDist)
  25.         {
  26.             transform.position += transform.forward * MoveSpeed * Time.deltaTime;
  27.             Debug.Log(MoveSpeed);
  28.             if (Vector3.Distance(transform.position, Player.position) <= MaxDist)
  29.             {
  30.                 StartCoroutine(SparseUpdateSecond());
  31.             }
  32.             // 在此处执行您在 Update 中通常要执行的所有常规操作。
  33.         }

  132.             }
  133.         }
  134.     }
  135. }

}

  2. 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。
  4. 我尝试了其他方法来移动汽车，但都没有成功。

  153.            }
  154.         }
  159.   }

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

答案1

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

  1. if (Vector3.Distance(transform.position, Player3.position) &gt;= MinDist)
  2.         {
  3.             transform.position += transform.forward * MoveSpeed * Time.deltaTime;
  4.             if (Vector3.Distance(transform.position, Player3.position) &lt;= MaxDist)
  5.             {
  6.               StartCoroutine(SparseUpdateFourth());
  7.               break;
  8.             }
  9.         // Do all the normal things you&#39;d do in Update here instead.
