如何指向插件（Bukkit）

Question

我需要类似：

Plugin plugin = this plugin

但我找不到任何指向此插件的内容，所以我在这里询问。

我的代码：

`package cz.untitled.main;

import cz.untitled.Untitled;
import io.papermc.paper.plugin.configuration.PluginMeta;
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;

        }
        else
        {
            Bukkit.getServer().getLogger().log(Level.INFO, ChatColor.RED + "Oh, You must be player to execute this!");
            return false;
        }
        return false;
    }
}

这只是因为字符限制。这只是因为字符限制。这只是因为字符限制。这只是因为字符限制。这只是因为字符限制。这只是因为字符限制。

Answer 1

MyPluginClass myPlugin = MyPluginClass.getPlugin(MyPluginClass.java); // returns instance of MyPluginClass

将

MyPluginClass

替换为扩展

JavaPlugin

的类的类名，它将返回它的实例。

请记住，类名应该是 PascalCase - 在你的情况下

serverselectcommand

应该是

ServerSelectCommand

。遵守该命名约定，将来就不会有问题。
