c# - 通过脚本找对撞机

Question

我有一个 list 脚本，我需要找到一个游戏对象并获取它的组件(碰撞器)，然后启用它。这是我的代码，你能告诉我哪里出错了吗。

public GameObject[] Inventory = new GameObject[3];
public Image[] InventorySlots = new Image[3];
public GameObject Ending;

private void Start()
{
   Ending = GameObject.Find("End Determination Object").GetComponent<Collider2D>; //this doesn't work
}

public void AddStoryItem(GameObject item)
{
    bool itemAdded = false;
    //to put items in inventory
    for (int i = 0; i < Inventory.Length; i++)
    {
        //check for empty slot
        if (Inventory[i] == null)
        {
            //place item
            Inventory[i] = item;
            InventorySlots[i].overrideSprite = item.GetComponent<SpriteRenderer>().sprite;
            Debug.Log(item.name + " hey you got an item");
            itemAdded = true;
            item.SendMessage("Store");
            break;
        }
    }
    //inventory full
    if (!itemAdded)
    {
        Debug.Log("it's full");
        //enable collider here

    }
}

看这个:

public GameObject Ending;

private void Start()
{
   Ending = GameObject.Find("End Determination Object").GetComponent<Collider2D>; //this doesn't work
}

它不会工作因为Ending是 GameObject 的一种但你正在分配 Collider2D当你这样做的时候Ending = GameObject.Find("End Determination Object").GetComponent<Collider2D>;

这会起作用(因为 GameObject.Find 返回 GameObject 的类型):

Ending = GameObject.Find("End Determination Object");

但是既然你想找一个Collider2D不是GameObject改变

public GameObject Ending;

到

public Collider2D Ending;

现在您可以:Ending = GameObject.Find("End Determination Object").GetComponent<Collider2D>(); .

通知()我在最后添加因为 GetComponent是一个函数。
