java - bukkit 命令已识别 n

Question

我正在制作一个带有服务器基本命令的插件，并且我已经添加了几个运行良好的事件。但是当我尝试添加命令时，它不起作用。 (在你问之前，我已经用一个简单的 sendMessage 替换了 onCommand 部分中的所有内容，并且它不执行任何操作)。当我执行该命令时，它只是告诉我在plugin.yml 中放入的用法。

这是我的代码:抱歉它真的很长

package com.pepsi.core;

public class Main extends JavaPlugin implements Listener {

    Bukkit.getLogger().info("PepsiCore >> Enabled!");

    getConfig().options().copyDefaults(true);
    saveConfig();

}

@Override

    Bukkit.getLogger().info("PepsiCore >> Disabled!");

}

public boolean onCommand(Command cmd, CommandSender sender, String cmdLbl, String[] args) {

    }

    return true;
}

@EventHandler
public void onPlayerChat(AsyncPlayerChatEvent e) {

    Player p = e.getPlayer();
    String uuid = p.getUniqueId().toString();
    String name = p.getName();
    String msg = e.getMessage();

    String rank = (String) getConfig().get("ranks." + uuid);

    if (rank == "guest") { e.setFormat(Util.transMsg("&fGuest &7&l" + name + " &8>> &f" + msg)); }

}

@EventHandler
public void onPlayerJoin(PlayerJoinEvent e) {

    Player p = e.getPlayer();
    String uuid = p.getUniqueId().toString();

    if (p.hasPlayedBefore() == false) {
        getConfig().set("ranks." + uuid, "guest");
        saveConfig();
        return;
    }

}

}

这是我的plugin.yml:

name: PepsiCore
author: P3pi
version: 1.0.3
main: com.pepsi.core.Main

commands:
    pcore:
        description: Core command
        usage: /pcore
    pepsicore:
        description: Core command
        usage: /pepsicore

感谢您的帮助

Bukkit 处理命令的方式是运行 JavaPlugin 类的 onCommand 方法。具体来说，onCommand 方法采用参数 CommandSender sender、Command command、String label、String[] args

正如 Vlexing 提到的，您的方法的参数顺序错误，因此在运行命令时它不会运行您的方法，而是从 JavaPlugin 运行 onCommand 方法> 仅包含return false;。由于您的plugin.yml，Bukkit 仍然可以识别您的命令，但是当它尝试运行您的方法时，它得到了false，因此它打印出了您的使用消息。

基本上，只需调整参数的顺序并遵循 Vlexing 的答案即可。
