我创建了一个协程。但没有延迟

Question

当我的物体接触到扳机时，它被摧毁并感染了新的感染。然后在 4 秒后它应该返回到之前的状态。通过协程延迟。但没有延迟。对象立即创建

public GameObject boxPrefab; 公共游戏对象 visibalBoxPrefab;

private void OnTriggerEnter2D(Collider2D collision)
{
    
    if (collision.gameObject.tag == "Flashlight")
    {
        Destroy(boxPrefab);
        Debug.Log("DESTROY");
        var cloneBox = Instantiate(visibalBoxPrefab, boxPrefab.transform.position, Quaternion.identity);
        Destroy(cloneBox, 2f);
        StartCoroutine(Break(cloneBox));
        
    }
}


IEnumerator Break(GameObject cloneBox)
{
   
    Instantiate(boxPrefab, cloneBox.transform.position, Quaternion.identity);
    yield return new WaitForSeconds(4f);
    
}

只想知道我哪里错了
