Hello@all,

 

I'm Googling since yesterday morning and followed every interesting thread in this forum, the bukkit forum and many other sources, but my problem is not solved.

 

I want to communicate between a mod and my spigot server. But neither messages sent from forge nor the messages sent from spigot/bukkit are received on the other side.

 

What I do:

 

Forge-Side:

    @EventHandler
    public void preInit(FMLPreInitializationEvent event) {
        network = NetworkRegistry.INSTANCE.newSimpleChannel("Channel");
        network.registerMessage(CommunicationMessage.Handler.class, CommunicationMessage.class, 0, Side.CLIENT);
        System.out.println("Channel registered as CLIENT Side with 0");
    }

 

public class CommunicationMessage implements IMessage {

    private String text;

    public CommunicationMessage() { }

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

    @Override
    public void fromBytes(ByteBuf buf) {
        text = ByteBufUtils.readUTF8String(buf);
    }

    @Override
    public void toBytes(ByteBuf buf) {
        ByteBufUtils.writeUTF8String(buf, text);
    }

    public static class Handler implements IMessageHandler<CommunicationMessage, IMessage> {

        @Override
        public IMessage onMessage(CommunicationMessage message, MessageContext ctx) {
            System.out.println(String.format("Received %s from %s", message.text, ctx.getServerHandler().playerEntity.getDisplayName()));
            return null; // no response in this case
        }
    }
}

 

On the Spigot/Bukkit Side

    @Override
    public void onEnable() {
        Bukkit.getMessenger().registerOutgoingPluginChannel(this, "Channel");
        Bukkit.getMessenger().registerIncomingPluginChannel(this, "Channel", new PacketHandler(this));
        this.getServer().getPluginManager().registerEvents(new PlayerLoginListener(this), this);
    }

 

    public void onPluginMessageReceived(String channel, Player player, byte[] message) {
        if(channel.equalsIgnoreCase("Channel")) {
            Bukkit.broadcastMessage(message.toString());
            if(message.toString().equalsIgnoreCase(((byte)0)+"reg")) {
                if(!plugin.players.contains(player))
                    plugin.players.add(player);
            }
        }

    }

 

So. What i want to do - i know that currently my forge mod have no code to answer ;-):

When the player joins the Spigot/Bukkit Server, Spigot/Bukkit sends "reg" over "Channel".

When forge receives "reg" over Channel it should answer with "reg" over channel. So, Spigot/Bukkit knows the players using the Forge Mod.

 

So. What i am doing wrong?

Should i to it another way?

Who can help?

 

Many thanks!

I've read this post and the other tutorial ~10 times.

 

I don't see any differences between my code and the code in the post you provided (except the discriminator, but there i tried both). Have I overlooked some thing?

 

Okay, thanks, i've corrected the byte[]-things. It totally clear.

 

But it doesn't solve my problem.

 

I do not receive any pluginmessages on both sides.

 

I changed it to outgoing only on bukkit-side to first get this way running.

 

Forge-Side:

    @EventHandler
    public void preInit(FMLPreInitializationEvent event) {
        network = NetworkRegistry.INSTANCE.newSimpleChannel("Channel");
        network.registerMessage(CommunicationMessage.Handler.class, CommunicationMessage.class, 0, Side.CLIENT);
        System.out.println("Channel registered as CLIENT Side with 0");
    }

 

public class CommunicationMessage implements IMessage {


    public CommunicationMessage() { }

    @Override
    public void fromBytes(ByteBuf byteBuf) {

    }

    @Override
    public void toBytes(ByteBuf byteBuf) {

    }


    public static class Handler implements IMessageHandler<CommunicationMessage, IMessage> {

        @Override
        public IMessage onMessage(CommunicationMessage message, MessageContext ctx) {
            System.out.println(String.format("Received"));
            return null; // no response in this case
        }
    }
}

 

Bukkit-Side:

    @Override
    public void onEnable() {
        Bukkit.getMessenger().registerOutgoingPluginChannel(this, "Channel");
        //Bukkit.getMessenger().registerIncomingPluginChannel(this, "Channel", new PacketHandler(this));
        this.getServer().getPluginManager().registerEvents(new PlayerLoginListener(this), this);
    }

 

    public void onPluginMessageReceived(String channel, Player player, byte[] message) {
        if(channel.equalsIgnoreCase("Channel")) {

            System.out.println(message[0]);
       }
   }

 

JoinListener:

event.getPlayer().sendPluginMessage(plugin, "Channel", new byte[]{0});

 

Any other ideas?

 

Uuuuhhhh.... thats not what i wanted to hear... ;-)

 

Do you know a good method to debug pluginmessages?

Showing all incoming and outgoing plugin messages in forge and in spigot/bukkit?
