Bukkit 1.20.1 插件：跨服务器传送 (BungeeCord & Spigot 联动)

以下是一个示例代码，用Java编写的Bukkit插件，适配BungeeCord与Spigot联动，允许玩家在A服务器使用/tpa命令传送到B服务器的好友身边。\n\njava\nimport org.bukkit.ChatColor;\nimport org.bukkit.command.Command;\nimport org.bukkit.command.CommandSender;\nimport org.bukkit.entity.Player;\nimport org.bukkit.plugin.java.JavaPlugin;\nimport org.bukkit.plugin.messaging.PluginMessageListener;\n\nimport com.google.common.io.ByteArrayDataInput;\nimport com.google.common.io.ByteArrayDataOutput;\nimport com.google.common.io.ByteStreams;\n\npublic class TeleportPlugin extends JavaPlugin implements PluginMessageListener {\n\n @Override\n public void onEnable() {\n getServer().getMessenger().registerIncomingPluginChannel(this, "BungeeCord", this);\n getServer().getMessenger().registerOutgoingPluginChannel(this, "BungeeCord");\n }\n\n @Override\n public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {\n if (cmd.getName().equalsIgnoreCase("tpa")) {\n if (!(sender instanceof Player)) {\n sender.sendMessage(ChatColor.RED + "Only players can use this command!");\n return true;\n }\n\n Player player = (Player) sender;\n if (args.length < 1) {\n player.sendMessage(ChatColor.RED + "Usage: /tpa <player>");\n return true;\n }\n\n String targetPlayer = args[0];\n sendTeleportRequest(player, targetPlayer);\n return true;\n }\n\n return false;\n }\n\n private void sendTeleportRequest(Player player, String targetPlayer) {\n ByteArrayDataOutput out = ByteStreams.newDataOutput();\n out.writeUTF("ConnectOther");\n out.writeUTF(player.getName());\n out.writeUTF(targetPlayer);\n\n player.sendPluginMessage(this, "BungeeCord", out.toByteArray());\n player.sendMessage(ChatColor.GREEN + "Teleport request sent to " + targetPlayer);\n }\n\n @Override\n public void onPluginMessageReceived(String channel, Player player, byte[] message) {\n if (!channel.equals("BungeeCord")) {\n return;\n }\n\n ByteArrayDataInput in = ByteStreams.newDataInput(message);\n String subChannel = in.readUTF();\n\n if (subChannel.equals("ConnectOther")) {\n String playerName = in.readUTF();\n String server = in.readUTF();\n\n if (playerName.equals(player.getName())) {\n player.sendMessage(ChatColor.GREEN + "You have been teleported to " + server);\n }\n }\n }\n}\n\n\n请确保你的项目中包含了以下依赖项：\n- BungeeCord\n- Spigot-API\n\n你可以根据自己的需求进行修改和扩展。这只是一个基本的示例，可能需要根据你的具体情况进行适当地调整。
