c# - Unity - 无法创建多个对象，且创建之间存在延迟

Question

我试图让协程每 0.2 秒一次生成一个对象，但是当我运行协程时，它会立即生成多个对象，没有任何延迟。我该如何解决这个问题并达到预期的结果？

我的代码:

        if (shotExtender > 0)
    {
        StartCoroutine("Timer");
    }
    else
    {
        StopCoroutine("Timer");
    }

协程

    IEnumerator Timer()
{
    while (objCounter < 3)//it should spawn only 3 objects
    {
        yield return new WaitForSeconds(0.2f);

        GameObject bullet = PhotonNetwork.Instantiate(bulletPref.name, bulletPosition, Quaternion.identity);

        objCounter++;
        Debug.Log("objCounter: " + objCounter + " maxBullets: "+maxBullets);
    }
    objCounter = 0;
    shotExtender = 0;//This stops the coroutine
}

Answer 1

如果此代码在更新内运行

if (shotExtender > 0)
{
   StartCoroutine("Timer");
}
else
{
   StopCoroutine("Timer");
}

您必须在开始该过程之前完成条件像这样

if (shotExtender > 0)
{
  shotExtender = 0;
   StartCoroutine("Timer");
}
else
{
   StopCoroutine("Timer");
}
