Question

我列出了这个会议室，但我不知道该怎么办。我还有其他脚本，但是我不知道我是否应该为DestroyChildren或其他内容编写脚本。我应该删除DestroyChildren吗？还是我应该做些改变？或添加一些东西来工作？当我开始游戏时，在创建房间时也会出现此错误，我应该在检查器中添加什么？

public class RoomListingsMenu : MonoBehaviourPunCallbacks
{
    [SerializeField]
    private Transform _content;
    [SerializeField]
    private RoomListing _roomListing;

    private List<RoomListing> _listings = new List<RoomListing>();
    private RoomsCanvases _roomsCanvases;


    public void FirstInitialize(RoomsCanvases canvases)
    {
        _roomsCanvases = canvases;
    }

    public override void OnJoinedRoom()
    {
        _roomsCanvases.CurrentRoomCanvas.Show();
        _content.DestroyChildren();
        _listings.Clear();
    }

    public override void OnRoomListUpdate(List<RoomInfo> roomList)
    {
        foreach (RoomInfo info in roomList)
        {
            //Removed from rooms list.
            if (info.RemovedFromList)
            {
                int index = _listings.FindIndex(x => x.RoomInfo.Name == info.Name);
                if (index != -1)
                {
                    Destroy(_listings[index].gameObject);
                    _listings.RemoveAt(index);

            }
            //Added to rooms list.
            else

                        listing.SetRoomInfo(info);
                        _listings.Add(listing);
                    }

似乎您缺少此扩展方法的某些“使用”或某些实现。

我会假设这是来自https://github.com/Mckenon/Unity-Utils/blob/master/Utils/Transform.cs

您可以使用整个库，也可以使用单个类Transform.cs，也可以根据需要编写自己的扩展类和方法：

using UnityEngine;

public static class TransformExtensions
{
    public static void DestroyChildren(this Transform t)
    {
        for (int i = t.childCount - 1; i >= 0; i--)
            MonoBehaviour.Destroy(t.GetChild(i));
    }
}

脚本给出类似_content.DestroyChildren（）的错误
