Bukkit / Spigot：插件 - 自定义GUI Shop错误

Question

我目前正在为我的服务器网络编写自己的GUI Shop，我面临两个奇怪的问题。

第一个问题是，每当我想获得带有Item ID 161的2个叶子和两个不同的Meta ID（0和1）时，我只会返回一个2的元ID。

以下是我在调试中获取项目数据的内容： Problem 1

这就是我在库存中得到的： Problem 1

但应该是这个（例如）：161/0或161/1

我从Spigot / Bukkit本身得到这个Item Meta，所以我不会自己获取它。

我遇到的下一个问题是，每当我想购买羊毛时，它只能完美地运行到第9个字节，然后它上面的所有东西每次都会让我回到橙色羊毛或粘土或玻璃。

这就是我如何展示物品：

if(t == ShopType.SHOP_DECORATION){
        inv = Bukkit.createInventory(null, 54, "Shop: Decoration");
        createDisplay(Material.WOOL, (byte)0, inv, 0, null, getShopLore("wool"));
        createDisplay(Material.WOOL, (byte)1, inv, 1, null, getShopLore("wool2"));

        createButtons(inv);
        p.openInventory(inv);
    }

这些显示在GUI中显示正确，但是当我想购买时，我总是在青色羊毛/粘土/玻璃后得到橙色羊毛或粘土或玻璃。

这是我给他们的方式：

    public static boolean withdrawPlayer(Player player, double amount, int am){
    double money = econ.getBalance(player);
    if(money < amount){
        return false;
    }
    econ.withdrawPlayer(player, amount);
    JSONObject json = Shop.getItemData(player);
    int itemID = json.getInt("item_id");
    byte itemMeta = (byte)json.getInt("item_data");
    ItemStack item = new ItemStack(itemID, 1, itemMeta);

    item.setAmount(am);
    player.sendMessage("Debug: " + item.getAmount() + " " + item.getType() + " -- Data: " + Shop.getData(item.getData()) + " ||| " + item.getData());
    player.getInventory().addItem(item);
    player.updateInventory();
    return true;
}

这就是我添加JSONObject的方式：

private static void addItem(String item, int price, ShopType type){
    priceList.put(item, price);
    slotList.put(item, type);
    JSONObject temp = new JSONObject();
    switch(type){
    case SHOP_REDSTONE:
        temp.put("slot", a);
        temp.put("type", type.toString());
        temp.put("name", item);
        temp.put("price", price);
        a++;
        break;
    case SHOP_ORES:
        temp.put("slot", b);
        temp.put("type", type.toString());
        temp.put("name", item);
        temp.put("price", price);
        b++;
        break;
    case SHOP_SEEDS:
        temp.put("slot", c);
        temp.put("type", type.toString());
        temp.put("name", item);
        temp.put("price", price);
        c++;
        break;
    case SHOP_FOOD:
        temp.put("slot", d);
        temp.put("type", type.toString());
        temp.put("name", item);
        temp.put("price", price);
        d++;
        break;
    case SHOP_DROPS:
        temp.put("slot", e);
        temp.put("type", type.toString());
        temp.put("name", item);
        temp.put("price", price);
        e++;
        break;
    case SHOP_MISC:
        temp.put("slot", f);
        temp.put("type", type.toString());
        temp.put("name", item);
        temp.put("price", price);
        f++;
        break;
    case SHOP_DECORATION:
        temp.put("slot", g);
        temp.put("type", type.toString());
        temp.put("name", item);
        temp.put("price", price);
        g++;
        break;
    }
    System.out.println("A: " +a);
    System.out.println("B: " +b);
    System.out.println("C: " +c);
    System.out.println("D: " +d);
    System.out.println("E: " +e);
    System.out.println("F: " +f);
    System.out.println("G: " +g);
    debug.add(temp);
}

这是当有人点击某个项目时运行的代码：

    Player p = (Player) e.getWhoClicked();
    int slot = e.getSlot();

    if (e.getSlotType().equals(SlotType.OUTSIDE)) {

}

所以，请问，我错过了什么或者我做错了什么？

Answer 1

对于第一个问题： new ItemStack（Material.LEAVES_2,1，（简称）0）; new ItemStack（Material.LEAVES_2,1，（简称）1）; 叶子的构造者应该看起来像这样。

关于第二个问题： Shop.getData究竟返回什么？ 如果您想给他一个类似于商品的商品，您可以执行以下操作：

p.getInventory().addItem(new ItemStack(e.getCurrentItem().getType(),1,e.getCurrentItem().getDurability()));

'：'之后的值（idk用英语调用;我是德语）被称为项目的持久性，被称为块的数据。另外，为了保持耐用性，Bukkit使用了short，但是对于块数据，它们使用了一个字节。
