[Packets] Bukkit -> Forge

keelfy · 29 Июл 2016

В общем, взялся я для туториала сделать пробный мод + плагин, дабы показать как происходит соединение плагина на ведре и мода на фордже.

Сообщения Forge -> Bukkit отправляются и принимаются успешно. Даже очень. ~~Аж страшно.~~
И все бы ничего, можно было и закончить на этом весь туториал, но хочется рассказать о большем и конечно с этим возникли проблемы...

Суть в том, что я, принимая пакет со строкой в плагине, хочу сразу отослать информацию. То бишь получается некий запрос на получение ин-фы от клиента.

Но беда в том, что я отправляю данные в мод с плагина, но в клиенте при расшифровке возникает ошибка.

Я не буду отправлять классы, в которых все это регистрируется, ибо они попросту не нужны, т.к. проблема в обработке пакетов.

Код:

public class MessageGet implements IMessage {

private String text;

public MessageGet(String text) {
this.text = text;
}

@Override
public void fromBytes(ByteBuf buf) {
System.out.println("from");
text = ByteBufUtils.readUTF8String(buf);
}

@Override
public void toBytes(ByteBuf buf) {
ByteBufUtils.writeUTF8String(buf, text);
System.out.println("to");
}

public static class Handler implements IMessageHandler<MessageGet, IMessage> {
       
       @Override
       public IMessage onMessage(MessageGet message, MessageContext ctx) {
           //System.out.println(String.format("Received " + message.text));
        System.out.println("on1");
           return null;
       }
   }
}

Код:

public class MessageListener implements PluginMessageListener {

private Main plugin;
public MessageListener(Main plugin) {
this.plugin = plugin;
}

@Override
    public void onPluginMessageReceived(String channel, Player player, byte[] message) {
if(channel.equals("info")) {

if(new String(message).contains("getInfo")) {
System.out.println(new String(message));
player.sendPluginMessage(plugin, "info", new String("testforclient").getBytes());
}
}
    }
}

Код:

  public static SimpleNetworkWrapper network; 
 
@EventHandler
public void preInit(FMLPreInitializationEvent event) {
 network = NetworkRegistry.INSTANCE.newSimpleChannel("info");
     network.registerMessage(MessageGet.Handler.class, MessageGet.class, 0, Side.CLIENT);
}

Код:

public void onEnable() {

Bukkit.getMessenger().registerOutgoingPluginChannel(this, "guildInfo");
Bukkit.getMessenger().registerIncomingPluginChannel(this, "guildInfo", new MessageListener(this));
}

Клиент не крашит при попытке получить пакет, лишь выкидывает с сервера с такой ошибкой:
