我正在創建一個流星雨，它從游戲對象列表中選擇一個隨機的空游戲對象。我希望每 2.33f 實例化一顆流星。然后程序應從列表中選擇一個新的隨機生成區域并重復直到 smallWaveCounter 達到 0。此代碼有效但它會不停地實例化流星，直到 smallWaveCounter 達到 0 并且實例化之間沒有暫停。我的問題是：為什么 IENumerator 似乎只在第一次運行時產生？如何讓它在每次觸發時更改隨機對象？[SerializeField]private List<GameObject> meteorSpawnSmall = new List<GameObject>(); private int smallCounter; private void Start(){ foreach(GameObject spawn in meteorSpawnSmall)//Counts objects in list { smallCounter++; } }void Update(){ if (showerStart == true) { StartCoroutine(SmallShower()); if(smallWaveCount <= 0) { showerStart = false; } } }IEnumerator SmallShower(){ if (smallWaveCount > 0) { yield return new WaitForSeconds(smallWaveTimer);// smallWaveTimer = 2.33f smallPickerNum1 = Random.Range(0, smallCounter - 1); // Needs to randomize each run smallPickerNum2 = Random.Range(0, smallCounter - 1); while (smallPickerNum2 == smallPickerNum1) { smallPickerNum2 = Random.Range(0, smallCounter - 1); } getSpawnZone1 = meteorSpawnSmall[smallPickerNum1];//Grabs the spawnzone from list getSpawnZone2 = meteorSpawnSmall[smallPickerNum2];//Grabs the 2nd spawn zone from list Instantiate(smallMeteor, getSpawnZone1.transform.position, Quaternion.identity); Instantiate(smallMeteor, getSpawnZone2.transform.position, Quaternion.identity); smallWaveCount--;//smallWaveCount starts at int 10 }}

它確實每次都在等待，但你每幀都執行協程，所以你無法區分差異。改變你的代碼有點像：
void Update()
{
if (showerStart == true) {
showerStart = false; //to ensure that your coroutine called once
StartCoroutine(SmallShower());
}
}
IEnumerator SmallShower()
{
while (smallWaveCount > 0)
{
yield return new WaitForSeconds(smallWaveTimer);// smallWaveTimer = 2.33f
smallPickerNum1 = Random.Range(0, smallCounter - 1); // Needs to randomize each run
smallPickerNum2 = Random.Range(0, smallCounter - 1);
while (smallPickerNum2 == smallPickerNum1)
{
smallPickerNum2 = Random.Range(0, smallCounter - 1);
}
getSpawnZone1 = meteorSpawnSmall[smallPickerNum1];//Grabs the spawnzone from list
getSpawnZone2 = meteorSpawnSmall[smallPickerNum2];//Grabs the 2nd spawn zone from list
Instantiate(smallMeteor, getSpawnZone1.transform.position, Quaternion.identity);
Instantiate(smallMeteor, getSpawnZone2.transform.position, Quaternion.identity);
smallWaveCount--;//smallWaveCount starts at int 10
}
}
