 [RequireComponent(typeof(Rigidbody2D))]

 public class Movement : MonoBehaviour
 {
     //storage for the object's rigidbody
     public Rigidbody2D rb2D;
     //the public modifier for speed so i can edit from outside
     public float speed;
     //reliably take movements each second in an even, reliable manner. 
     void FixedUpdate()
     {
         //i move left and right if  i use "a" or "d or "left" or "right" 
         float moveX = Input.GetAxis("Horizontal");
         //I move up and down if i use "w" or "s" or "up" or "down"
         float moveY = Input.GetAxis("Vertical");
         //Vector inputs the move directions into a vector2 so i can move
         Vector2 move = new Vector2(moveX, moveY);
         rb2D.velocity = move * speed;
     }
     //following two methods are for the respective spikey builds
     public void slow()
     {
         print("Shit, spike's got me!");
         speed = .3f;
         StartCoroutine(PauseTheSlowdown(2.1f));
         speed = 1;
     }
     public void Bigslow()
     {
         print("HOLY CRAP THAT HURT");
         speed = 0f;
         StartCoroutine(PauseTheSlowdown(3.7f));
         speed = 1;
     }

     IEnumerator PauseTheSlowdown(float seconds)
     {
         print("Pause this crap");
         yield return new WaitForSecondsRealtime(seconds);
     }

 }

我在这里遇到了一些问题，我的代码似乎完全正常。它运行，然后当一个外部脚本从任何一个尖峰方法中拉出时，它的行为就像协同程序甚至没有那样，并且从慢速向后移动到全速。除了协同程序之外没有任何错误或问题，只是不会导致等待发生。我错过了一些明显的东西吗？

您无法将必须暂停的代码放入正常功能中。你必须把它放在协程函数中。

例如，在Bigslow函数中，Speed变量将设置为0。 PauseTheSlowdown协程将启动。 Unity将仅在PauseTheSlowdown函数中等待一帧，然后返回速度设置为Bigslow的{{1}}。它不会等待，因为您是从1函数启动它。

您有两种选择：

1 。将void和slow函数设为Bigslow而不是IEnumerator，然后在调用void时产生。

StartCoroutine

在致电public IEnumerator slow() { print("Shit, spike's got me!"); speed = .3f; yield return StartCoroutine(PauseTheSlowdown(2.1f)); speed = 1; } public IEnumerator Bigslow() { print("HOLY CRAP THAT HURT"); speed = 0f; yield return StartCoroutine(PauseTheSlowdown(3.7f)); speed = 1; } IEnumerator PauseTheSlowdown(float seconds) { print("Pause this crap"); yield return new WaitForSecondsRealtime(seconds); }之前请注意yield return。

2 。移动您要执行的代码并等待一段时间到StartCoroutine协同程序函数：

PauseTheSlowdown

尝试使用协同程序暂停方法，我做错了什么？
