在 Bukkit 中使用多个类作为命令？

问题描述 投票：0回答：1

最近我启动了一个 Bukkit 插件，但由于使用两个类（main 和 CommandExecutor）而遇到了麻烦。我已经尝试了所有方法，但是当我加载插件时，它会抛出一个错误，该错误位于帖子末尾。

主要（称为 ekits.java）：

package me.mucapapipa.ekits;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;

public class ekits extends JavaPlugin implements Listener {


@Override
public void onEnable() {
    System.out.println("Main plugin enabled");
    getCommand("pvp").setExecutor(new NormalPlayer(this));
    getServer().getPluginManager().registerEvents(this, this);
}
@Override
public void onDisable() {
    System.out.println("Main plugin disabled");
}


}

CommandExecutor（称为NormalPlayer）：

package me.mucapapipa.ekits;

import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class NormalPlayer extends JavaPlugin implements CommandExecutor {

@SuppressWarnings("unused")
private ekits core;
public NormalPlayer(ekits core) {
        this.core = core;
}

private String kit;

public boolean onCommand(CommandSender sender, Command cmd, String CommandLabel, String[] args) {
    
    if (sender instanceof Player) {
        Player player = (Player) sender;
        if (cmd.getName().equalsIgnoreCase("pvp")) {
            kit = "PvP";
            player.getInventory().clear();
            player.getInventory().addItem(new ItemStack(Material.DIAMOND_SWORD));
            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));
            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));

            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));
            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));

            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));
            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));
            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));

            player.getInventory().addItem(new ItemStack(Material.MUSHROOM_SOUP));
            /* We then set the armor */
            player.getInventory().setBoots(new ItemStack(Material.IRON_BOOTS));
            player.getInventory().setHelmet(new ItemStack(Material.IRON_HELMET));
            player.getInventory().setLeggings(new ItemStack(Material.IRON_LEGGINGS));
            player.getInventory().setChestplate(new ItemStack(Material.IRON_CHESTPLATE));
            
            player.sendMessage(ChatColor.GRAY + "~ " + ChatColor.AQUA + "Kit: " + kit);
        }
        else {
            sender.sendMessage("The console should not play. It would be so OP.");
        }
    }
    
    return true; }
}

public class NormalPlayer extends JavaPlugin implements CommandExecutor

为什么你的命令执行器要扩展主插件类？这就是导致双重初始化的原因，删除该超类可能会修复代码。
