I am trying to get all servers on a BungeeCord network, and it is returning errors. Here is the error: https://paste.helpch.at/yudiqiteni.sql

#

Here is my code: https://paste.helpch.at/bicisitado.cs

How do you register and unregister the channel

south sentinel Nov 10, 2021, 12:11 AM

#

    @Override
    public void onEnable() {
        instance = this;
        this.getServer().getMessenger().registerOutgoingPluginChannel(this, "BungeeCord");
        this.getServer().getMessenger().registerIncomingPluginChannel(this, "BungeeCord", lobbyGui);
    }

    @Override
    public void onDisable() {
        this.getServer().getMessenger().unregisterOutgoingPluginChannel(this);
        this.getServer().getMessenger().unregisterIncomingPluginChannel(this);
    }```

#

Can you spot the mistake yourself?

south sentinel Nov 10, 2021, 12:13 AM

#

no

strange fox Nov 10, 2021, 12:14 AM

#

Would presume this

south sentinel Nov 10, 2021, 12:14 AM

#

error happens on sending the message

#

but that is a issue

#

thanks for pointing that out

strange fox Nov 10, 2021, 12:15 AM

#

Yeah actually idr if they switched the channel for bungee

south sentinel Nov 10, 2021, 12:16 AM

#

the error happens on this line: p.sendPluginMessage(LobbySystem.getInstance(), "BungeeCord", byteArrayOutputStream.toByteArray());

strange fox Nov 10, 2021, 12:19 AM

#

org.bukkit.plugin.messaging.StandardMessenger.validateAndCorrectChannel(StandardMessenger.java:503)

#

Can you send that method through paste?

#

I’m curious

@Deprecated
    @NotNull
    public static String validateAndCorrectChannel(@NotNull String channel) {
        if (channel == null) {
            throw new IllegalArgumentException("Channel cannot be null");
        }
        // This will correct registrations / outgoing messages
        // It is not legal to send "BungeeCord" incoming anymore so we are fine there,
        // but we must make sure that none of the API methods repeatedly call validate
        if (channel.equals("BungeeCord")) {
            return "bungeecord:main";
        }
        // And this will correct incoming messages.
        if (channel.equals("bungeecord:main")) {
            return "BungeeCord";
        }

#

Ah try using bungeecord:main instead

south sentinel Nov 10, 2021, 12:22 AM

#

alright

strange fox Nov 10, 2021, 12:22 AM

#

Also for the record I’d suggest having a constant (public static final String) for the channel

#

So you only have to change it in one place

#

(And no it doesn’t hit performance)

south sentinel Nov 10, 2021, 12:38 AM

#

alright

#

now

#

I am having issues with something else

#

a general bungeecord issue

#

it wont connect me to one of my servers

strange fox Nov 10, 2021, 12:41 AM

#

You’re trying to connect from one to another?

#

Through plugin messaging with the bungeecord channel?

south sentinel Nov 10, 2021, 12:42 AM

#

this is just connecting to the server

#

I cant test that

#

until this

#

so

#

I have it randomly get 1 of like 40 lobbies, and then send you to it on join, well rn, I am getting this error. [19:39:17 INFO]: [riches_exe|/127.0.0.1:57042] <-> ServerConnector [LOBBY2] has connected [19:39:17 INFO]: [riches_exe] disconnected with: Could not connect to a default or fallback server, please try again later: io.netty.channel.AbstractChannel$AnnotatedConnectException [19:39:17 INFO]: [/127.0.0.1:57042|riches_exe] -> UpstreamBridge has disconnected [19:39:17 WARN]: No client connected for pending server! [19:39:17 INFO]: [riches_exe|/127.0.0.1:57042] <-> ServerConnector [LOBBY2] has disconnected

strange fox Nov 10, 2021, 12:44 AM

#

How do you connect the player?

south sentinel Nov 10, 2021, 12:44 AM

#

pp.connect(sv);

#

sv = LobbySystem.getInstance().getRandomLobby();

strange fox Nov 10, 2021, 12:45 AM

#

pp?

south sentinel Nov 10, 2021, 12:45 AM

#

ProxiedPlayer pp = LobbySystem.getInstance().getProxy().getPlayer(e.getPlayer().getUniqueId());

strange fox Nov 10, 2021, 12:45 AM

#

Oh we are in bungeecord now?

south sentinel Nov 10, 2021, 12:45 AM

#

yeah, this connects the player to a random lobby, sorry if I didnt specify that first

strange fox Nov 10, 2021, 12:46 AM

#

Send the full code

#

Including getRandomLobby method

#

And the snippet where you connect

south sentinel Nov 10, 2021, 12:46 AM

#

    @EventHandler
    public void onPlayerJoin(PostLoginEvent e) {
        String type = CustomConfigFile.getConfig().getString("config.join-type");
        ProxiedPlayer pp = LobbySystem.getInstance().getProxy().getPlayer(e.getPlayer().getUniqueId());
        ServerInfo sv;
        if (type.equals("RANDOM")) {
            sv = LobbySystem.getInstance().getRandomLobby();
        }
        else {
            sv = LobbySystem.getInstance().getProxy().getServerInfo("LOBBY2");
        }
        System.out.println(ChatColor.AQUA + "[LobbySystem] >> " + ChatColor.GOLD + "New Player Connected. Sending them lobby " + sv.getName());
        pp.connect(sv);
    }```

#

    public ServerInfo getRandomLobby() {
        Random random = new Random();
        if(lobbies.size() <=0){
            return null;
        }else{
            int ran = random.nextInt(lobbies.size());
            return getInstance().getProxy().getServerInfo(lobbies.get(ran));
        }
    }```

#

it did work

#

I dont know what I did

strange fox Nov 10, 2021, 12:48 AM

#

Wat is the type of lobbies?

south sentinel Nov 10, 2021, 12:48 AM

#

public ArrayList<String> lobbies = new ArrayList<>();

strange fox Nov 10, 2021, 12:48 AM

#

Ah okay

#

Wait does it work now?

south sentinel Nov 10, 2021, 12:50 AM

#

it did work

#

Idk what I did

#

but now it doesnt

strange fox Nov 10, 2021, 12:51 AM

#

Use ServerConnectEvent instead

south sentinel Nov 10, 2021, 12:51 AM

#

on the server LOBBY2 this appears in the console: [19:39:17 INFO]: UUID of player riches_exe is 9d8784f3-aec6-36b9-a449-418e6c366321 [19:39:17 INFO]: riches_exe lost connection: Disconnected

strange fox Nov 10, 2021, 12:52 AM

#

and then use ServerConnectEvent::setTarget

south sentinel Nov 10, 2021, 12:59 AM

#

alright

#

I got it working

#

but now I may have another issue

#

it might be 2 things

#

messages sent to bungeecord:main are not being received by the server
I am sending a message, and not waiting long enough for the response
