unity StartCorountine从其他脚本调用时未唤醒

Question

我有一个带有while循环的IEnumerator，它应该运行100次，当我从同一脚本中的start方法调用此方法时，它可以完美地运行。但是，当我从另一个脚本调用IEnumerator时，它将被调用，而while循环仅运行一次。

 public class script1: MonoBehaviour
 {
  private void Start()
     {
         //StartCoroutine(StartCountdown(3));
        // When I call it here the while loop runs 100 
     }
  public IEnumerator StartCountdown(float countdownValue)
     {
         float waiteTime = countdownValue / 100;

         int loopNumber = 100;
         //float idk = 0;
         while (loopNumber > 0)
         {
             Debug.Log("aufgerufen");
             circle.fillAmount -= 0.01f;

             yield return new WaitForSeconds(waiteTime);
             loopNumber -= 1;
         }
     }
 }

 public class script2 : MonoBehaviour
 {
 public void GameOver()
     {

         panel.SetActive(true);
         Time.timeScale = 0;

         GameObject circle = GameObject.FindGameObjectWithTag("LoadCircle");
         StartCoroutine(circle.GetComponent<LoadCircle>().StartCountdown(3));

         //When  I call it from here the while loop only run once
     }
 }
