求教！删除指定节点下的克隆预制体

怎么创建，怎么删除，创建的时候就该赋好值

找不到就自己写扩展方法找

public static class TransformExtensions{
public static GameObject FindChild(this Transform transform, string name){
if (transform.childCount == 0) return null;
Queue<Transform> childs = new Queue<Transform>();
for (int i = 0; i < transform.childCount; i++){
childs.Enqueue(transform.GetChild(i));
}
Transform current;
while(childs.Count != 0){
current = childs.Dequeue();
if (current.gameObject.name.Equals(name))
return current.gameObject;
if (current.childCount == 0) continue;
for (int i = 0; i < current.childCount; i++){
childs.Enqueue(current.GetChild(i));
}}
return null;
}
}

foreach (Transform item in father)
{
Destroy(item.gameObject);
}
easy
