java - 从另一个类导入命令参数

Question

我现在必须在插件上工作几天左右，但我不确定如何做到这一点。我有一个命令/punish，它会打开一个 list ，管理员可以在其中对 arg[0] 中的玩家静音、踢、禁止或警告玩家。一旦命令打开第一个库存，我就创建了一个名为 guievents 的不同类来控制库存。我的问题是，如何将参数从一个类中的命令获取到另一个类。我在谷歌上搜索了一段时间，大多数时候我发现人们使用 HashMap ，但是，我从来不太明白他们是如何做到这一点的，或者我是否应该使用 HashMap 。命令类:

在第二个屏幕截图中，我放置了一个临时“名称”作为占位符，因为我不知道要放置什么。如果有人要回复，您能否解释一下您在做什么，这样我就不会再次达不到这一点。谢谢

Answer 1

您可以使用 HashMap，

你应该做的是在你的 CommandClass 中创建一个 HashMap。

将 Player 对象设为 Key，并将 arg(s) 设为值，如下所示:HashMap myHashMap - 如果是单个参数。

HashMap myHashMap - 如果有多个参数。

然后，每次打开 GUI 之前，您都应该将 Player 和 Arg 放入 HashMap 中。您应该在命令类中实现用于获取值的方法，例如 public String getArg(Player player)，并返回值。还有一个名为 public void removeArgs(Player player) 的删除方法(这将防止错误)，应该在 GUI 关闭时或您喜欢的任何时候调用它。

希望您能从中找到任何用处。
