Question

我将所有GameObjects放在一个列表下的场景中。以下是shelf.cs中用于删除游戏对象的函数。我将该函数分配给一个按钮，以便它获取输入值并找到哪个Gameobject的值小于输入值。然后删除。问题是每当我点击游戏预览中的按钮时，它都不会删除游戏对象。没有警告。我调试它是否收到所有输入，它确实。只是不删除GameObjects。

为什么？

public void Process(){
    int user_apple,user_lemon,user_watermelon;

    user_apple = int.Parse (input_apple.text);
    user_lemon = int.Parse (input_lemon.text);
    user_watermelon = int.Parse (input_watermelon.text);

    Debug.Log (user_apple+" "+user_lemon+" "+user_watermelon);

    for(int i = players.Count - 1; i >= 0; i--)
    {   if(players[i].name == "Lemon")
        {
            if(players[i].GetComponent<Apple>().weight <= user_apple)
            {   Debug.Log ("wat u want");
                Destroy(players[i]);
            }players.RemoveAt(i);

        }
    }
}

如果我这样说的话，

public void Process(){
    int user_apple,user_lemon,user_watermelon;

    user_apple = int.Parse (input_apple.text);
    user_lemon = int.Parse (input_lemon.text);
    user_watermelon = int.Parse (input_watermelon.text);

    Debug.Log (user_apple+" "+user_lemon+" "+user_watermelon);
    if(players[2].GetComponent<Lemon>().weight <= user_apple)
    {   Destroy(players[2]);
        players.RemoveAt(2);
    }
}

它会出现如下错误

这可能不是正确的解决方案尝试从Process Function调用一个协同例程并产生循环，以便它运行每一帧。

无法删除GameObject
