我的問題是關於向對象添加更多的字符串條目

Question

我的問題是關於如何向MakeSpawner對象添加多個字符串？

此創建的對象具有13個單獨的字符串條目。

在當前配置中，它生成3個單獨的生成對象，每個對象只有一個字符串。 我需要制作一個至少包含八個單獨的刺項的物品。

namespace Server
{
    public class GenItems
    {
        private static int m_Count;


        private const int ICount = 8;
        private const int HomeRange = 20;
        private const bool TotalRespawn = false;

        public static void Initialize()
        {
            CommandSystem.Register("GenItems", AccessLevel.Administrator, new CommandEventHandler(Generate_OnCommand));
        }

        [Usage("GenItems")]
        [Description("Generates Items")]
        private static void Generate_OnCommand(CommandEventArgs e)
        {
            Parse(e.Mobile);
        }

        public static void Parse(Mobile from)
        {

            from.SendMessage("Generating all items...");


   MakeSpawner(new string[] { "aaa", "bbb", "ccc" },  2850, 810, 0);



        }

        private static Queue m_ToDelete = new Queue();

        public static void ClearSpawners(int x, int y, int z)
        {
            IPooledEnumerable eable = Map.Sample.GetItemsInRange(new Point3D(x, y, z), 0);

            foreach (Item item in eable)
            {
                if (item is Spawner && item.Z == z)
                    m_ToDelete.Enqueue(item);
            }

            eable.Free();

            while (m_ToDelete.Count > 0)
                ((Item)m_ToDelete.Dequeue()).Delete();
        }

        private static void MakeSpawner(string[] types, int x, int y, int z)
        {
            if (types.Length == 0)
                return;

            ClearSpawners(x, y, z);

            for (int i = 0; i < types.Length; ++i)
            {

                Spawner sp = new Spawner(types[i]);

                sp.Count = ICount;
                sp.HomeRange = HomeRange;

                sp.MoveToWorld(new Point3D(x, y, z), Map.Sample);

                if (TotalRespawn)
                {
                    sp.Respawn();
                    sp.BringToHome();
                }

                ++m_Count;
            }
        }
    }
}

由於我仍然是C＃的新手，所以我沒有主意。

Answer 1

要允許您將多個生物名稱傳遞給Spawner ，您應該像這樣更改Spawner的構造函數：

[Constructable]
public Spawner(params string[] creatureName ) : base( 0x1f13 )
{
    InitSpawn( 1, TimeSpan.FromMinutes( 5 ), TimeSpan.FromMinutes( 10 ), 0, 4, creaturesName.ToList() );
}

然后像這樣修改您的MakeSpawner方法：

private static void MakeSpawner(string[] types, int x, int y, int z)
{
    if (types.Length == 0)
        return;

    ClearSpawners(x, y, z);

    Spawner sp = new Spawner(types);

    sp.Count = ICount;
    sp.HomeRange = HomeRange;

    sp.MoveToWorld(new Point3D(x, y, z), Map.Sample);

    if (TotalRespawn)
    {
        sp.Respawn();
        sp.BringToHome();
    }

    ++m_Count;

}

注意： params修飾符允許您傳遞單個字符串（ new Spawner("a") ），許多字符串（ new Spanwer("a", "b", "c") ）或字符串數​​組（ new Spanwer(types) ）為相同的方法。 我還稍微修改了您的代碼，以利用LINQ（ using System.Linq ）進行到List<string>的轉換。

現在，我唯一擔心的是ClearSpawners(x, y, z); ：如果您添加多個具有相同x，y，z的獨立生成器，那么（大概）會清除舊的生成器。 我猜想，由於這些是Spanwers，所以可能還不錯，並且每個位置只有一個生成器。
