Question

我正在尝试创建一种方法，可以让我更轻松地添加项目。创建库存很容易。这是我的代码。这是问题，每当我右键点击我的发光石灰尘时，它会抛出偶数异常错误，我不知道为什么。这是每当有人右键点击发光石灰尘时它应该做的事情，它应该打开一个绿色的名为“小工具”的库存。库存中有一个名为“HidePlayers”的项目

错误

在stacktrace中：

Caused by: java.lang.IllegalArgumentException: Chests must have a size that is a multiple of 9!

Stacktraces是你的朋友！如果您想了解如何理解错误消息并自行调试，请阅读此内容：https://stackoverflow.com/a/3988794/3476226。

要解决您的具体问题，您应该只是将10方法的这一行中的AddGadget更改为9或其他倍数，因为库存总是有九列所以创建一个大小为9的库存将使一个9列乘1行，如果有18个槽，则为9x2,27将为9x3，依此类推。

GadgetMenu = KInventoryCreate(10, ChatColor.GREEN + "Gadgets");

但更好的是，只需修改您的KInventoryCreate方法并返回类似Bukkit.createInventory(null, 9*rows, invname);的内容而不是原始的插槽号，这样您就可以安全地再次犯同样的错误。

Bukkit创建自定义方法。问题
