用Java写一个基于Paper1201的 玩家用指令打开末影箱功能

以下是一个使用Java编写的基于Paper 1.20.1版本的玩家用指令打开末影箱功能的示例代码：

import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.command.ConsoleCommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;
import org.bukkit.plugin.Plugin;
import org.bukkit.plugin.java.JavaPlugin;

public class EnderChestPlugin extends JavaPlugin implements Listener {
    private Plugin plugin;
    
    @Override
    public void onEnable() {
        plugin = this;
        Bukkit.getPluginManager().registerEvents(this, this);
    }
    
    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (label.equalsIgnoreCase("enderchest")) {
            if (sender instanceof Player) {
                Player player = (Player) sender;
                openEnderChest(player);
                return true;
            } else if (sender instanceof ConsoleCommandSender) {
                sender.sendMessage("该指令只能由玩家执行！");
                return true;
            }
        }
        return false;
    }
    
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        Action action = event.getAction();
        Block block = event.getClickedBlock();
        
        if (action.equals(Action.RIGHT_CLICK_BLOCK) && block.getType().equals(Material.ENDER_CHEST)) {
            event.setCancelled(true);
            openEnderChest(player);
        }
    }
    
    private void openEnderChest(Player player) {
        Inventory enderChestInventory = Bukkit.createInventory(null, 27, "末影箱");
        ItemStack[] enderChestContents = player.getEnderChest().getContents();
        enderChestInventory.setContents(enderChestContents);
        
        ItemStack closeItem = new ItemStack(Material.BARRIER);
        ItemMeta closeItemMeta = closeItem.getItemMeta();
        closeItemMeta.setDisplayName("关闭");
        closeItem.setItemMeta(closeItemMeta);
        
        enderChestInventory.setItem(26, closeItem);
        
        player.openInventory(enderChestInventory);
    }
}

请注意，此代码是基于Paper 1.20.1版本编写的，可能不适用于其他版本。你需要在你的服务器上安装Paper 1.20.1版本，并将此插件编译为.jar文件后放入服务器的插件文件夹中。

在游戏中，玩家可以使用命令/enderchest来打开末影箱，或者右键点击一个末影箱也能打开。末影箱界面将显示玩家的个人末影箱内容，并在最后一格放置一个“关闭”按钮。
