you cannot have overlapping method names with the same parameters in java

#

let alone the same signature

fair flame
#

I found it but now i have this error 'class' or 'interface' expected

#

.

wide maple
#

you dont need to ping me a second after you type that.

#

I was checking if the Command class is an interface

#

its not

#

show your whole code + line numbers + error

fair flame
#

Okey and how do i fix it? (I am not very good at coding thats why i have many questions)

wide maple
#

I cant help unless you read what I write.

fair flame
wide maple
#

What’s the name of your file

fair flame
#

The folder its in is a own folder and its called hub and the file is called Hub and its in the folder hub

wide maple
#

on your second-to-last line there’s an extra }

#

remove it.

fair flame
#

Now is all errors away

#

But when i tried to run it and get the java file i got the error Cannot Resolve symbol "Hub"

wide maple
#

that’s because you misspelled your class name. It should be “Hub”

#

if it still shows up then, delete the import and import it again

fair flame
#

ProxyServer.getInstance().getPluginManager().registerCommand(this, new hub.Hub(this));
Even if i set it to "Hub" ore "hub" its still not working and if i remove the import and add it again not working

wide maple
fair flame
#

How do you mean?

fair flame
sleek jackal
#

remove the .hub()

#

just new hub()

fair flame
# sleek jackal just new hub()

ProxyServer.getInstance().getPluginManager().registerCommand(this, new hub()(this));
Unexpected token
Not a statement
';' expected
')' expected

sleek jackal
#

remove the (this)

fair flame
#

But im gonna try if its working tommorow

well for one you are trying to save null to a file

short wedge
#

To get 1.7 working on waterfall we just needa do the protocols right?

wide maple
#

Velocity supports 1.7 out of the box if you don't want to deal with that

short wedge
wide maple
short wedge
#

it's 1.19?

wide maple
#

Maybe they'll even release updates publicly again if you open an issue. Don't know/don't care

#

Not sure

#

Says last updated 2022?

short wedge
#

its 1.19

wide maple
#

I guess then

short wedge
short wedge
lean gobletBOT
#

use a supported client version? seeing as that's not really related to waterfall that's outside of the support we can provide

#

if you want 1.19.1+ support you will need to get them to update it/update it yourself I guess?

#

*1.19.3 I mean

wide maple

# short wedge its 1.19

So Joshua must have seen that message because by some stupid miracle the fork just got updated.

in which occasion is this error thrown? im again working with scoreboard and packets. This time, with the ScoreboardScore packet

wide maple
#

That's all that that says

zenith grotto
#

i tried to see with the debugger but nothing is null, i'll check it again later

trail plume
#

Look at the source code

#

All we can see is that something in the scoreboard packet is null that shouldn't be

#

can custom channel registered multiple times?

channel registeration code is simple

        plugin.getServer().getMessenger().registerIncomingPluginChannel(plugin, BUNGEE_HOOK_CHANNEL_NAME, new BungeeListener());
        plugin.getServer().getMessenger().registerOutgoingPluginChannel(plugin, BUNGEE_HOOK_CHANNEL_NAME);

...
    private static final String CHANNEL_SUFFIX = "bungee_messenger";
    public static final String BUNGEE_HOOK_CHANNEL_NAME = "siglib:" + CHANNEL_SUFFIX;

SigLib.jar is a server custom library that we depend upon.

server A , server B, lobby all have SigLib.jar

so all server will try to register channel .
It works fine when server I stop and restart server A and B together

problem

sending data with custom registered channel happens 2 times or 3 times , not even sure of the pattern

setup

server A , B , lobby all have SigLib in their servers 
all register same channel

reproduction

proxy + server A, B , lobby are up
stop server A and restart
data sends 2 or 3 times in server A
lean terrace
wide maple
#

^ the player part:
If you have player 1 connected to server A
Then server A will be able to talk to the proxy
Server B which has no player connected to it will not

The plugin channels piggyback of the player connections: no player, no communication

Also: if you use serverA .sendmessage(...) on bungee
and you have both player 1 and player 2 connected to server A at the same time then the message will be sent twice: once for every player

Hey guys, why when i use ServerInfo#ping the first time it works but after that is always timeout

#

Im using this function to make sure the ping dont go long than 5 seconds:

public static void ping(ServerInfo info, Callback<ServerPing> callback) {
        CompletableFuture.runAsync(() -> {
            final CompletableFuture<Void> future = new CompletableFuture<>();

            info.ping((result, error) -> {
                callback.done(result, error);
                future.complete(null);
            });

            try {
                future.get(5, TimeUnit.SECONDS);
            } catch (final Exception e) {
                callback.done(null, e);
            }
        });
    }

But not sure if the ping have some sort of intenral delay, let me know

#

Even if i dont have that timeout of 5 seconds some time later i get "io.netty.handler.timeout.ReadTimeoutException"

trail plume
#

No, it just creates a socket and sends some crud over it and waits for a response

sage bronze
#

Because if players can still join the server and the first ping works there is something weird

#

I mean not sure how this could be about wrong address/ports

#

Could be that other plugins are messing somehow with that but is still weird

#

and sorry for the ping

Can i use kyori Adventure Component
importing via Gradle is no problem

Or is there any other way to use Hex colors in Waterfall messages?

not without the platform adapter

Cant have things just working ._.

just use velocity

Any idea where i need to change stuff?

trail plume
#

it's defined in the annotation

#

it's basically the plugin name

@Plugin(
        id = "Velocity",
        name = "Velocity",
        version = BuildConstants.VERSION,

turbid mural
#

Is it possible with the API to delay the join in the server and while player is waiting to join, a message in their client is sent?

Sort of like 2b2t that has a queue, where you don't left the server, but you are like stuck in the joining screen that gets updated with your queue position(this is an example of what I mean)

subtle radish
#

they do that with a limbo server

#

you cant stall making a connection to a backend server, and even if you could, the only thing the player would see would be the loading world screen or whatever

#

well you can stall it, but not for very long

turbid mural
#

to do things like checks and etc, is it better to use the HandshakeEvent?

chilly sequoia
#

Is there a way that Waterfall can catch Direct Messages?

trail plume
#

er, direct messages?

#

if you mean the commands, basically; yes; worse case, replace the commands on the proxy, or see if the chat event fires

bleak current
#

Hey! Not sure if this is the right channel but I plan on making my mini game server that runs paper and waterfall multi regional (united states and Europe) without needing to have excess lag from the proxy, is there a way to bypass this lag with waterfall or do I need velocity or something else.

snow bolt
#

it is a proxy

#

a proxy is an intermediary server between the minecraft client and minecraft server

#

it will always add latency

bleak current
#

But don't servers like hypixel have different servers in different regions?

snow bolt
#

no

bleak current
#

Oh

snow bolt
#

that is the only reason hypixel has been asking for a transfer packet

#

it is the only sane way of handling multi-region minecraft servers

bleak current
#

So if I manage to do this I'll be ahead of hypixel?

snow bolt
#

it's not possible

#

you're essentially asking if it's possible to remove the 100ms latency that occurs when crossing the ocean

#

i don't think that's physically possible yet

#

either you use a transfer packet which doesn't exist, or you split your network in two and host US & EU servers; doing this has a larger impact on your community than anything else

bleak current
#

Ok, thanks

#

Thought it was possible

snow bolt
#

perhaps one day in a future minecraft version

#

but realistically, no sane option unfortunately

bleak current
#

What if I do an insane way until it comes

snow bolt
#

it'd be one of the above two options

#

okay well option 3 is running a modded client, but at that point your possiblities are pretty endless anyways

bleak current
#

Alright thanks for all the info

basically, you can customise everything after "Waterfall " inside of the waterfall config, thing it's like game_versions or something

how can i create a docker-compose.yml with a waterfall proxy and paper servers?

snow bolt
#

not a waterfall-dev question

#

and you're also kinda on your own with that

either create your own docker image or use something like itzg/minecraft-server

there are no official docker images

Hey! I was just wondering if there's any way of getting the entire waterfall project as a dependecy, because the "waterfall-api" artifact is not complete for all the things I need to do.

trail plume

you'd need to publish it to your own maven reposomehow

but you still shouldnt really do this, the API exists for a reason

Hello, does someone know a good plugin that sends you always on a different lobby server when joining?

mental solstice
#

when doing commandSender.hasPermission(x), if the commandsender is actually the console, will it always return true or always return false (or null)

potent lichen
#

It will return true. Your question is actually a very good one.

mental solstice
barren cloud
#

How would I go about checking if a player is vanished, on PostLoginEvent ? It would have to somehow check with the initial server somebody logs into, right?

#

basically. I have join/leave messages turned off on the servers, and I have a join and leave just for when somebody joins and leaves the proxy.

#

but when people join vanished, I want to not show a login message.

onyx elm
#

If I have a Connection object and I call Connection#createArrayOf() and receive a SQLFeatureNotSupportedException, is that due to Waterfall using a JDBC driver that doesn't support that call or something else?

potent lichen
#

That is because the driver providing your Connection implementation does not support this method. That may be a JDBC driver shipped with Waterfall or whatever other JDBC driver you are using. Sometimes, the JDBC driver cannot support the method because the RDMS doesn't provide the underlying feature; other times, it is simply unimplemented.

onyx elm
#

I'm using HikariCP I haven't explicitly defined any other driver for JDBC

boreal crown
#

Is getServerInfo returning null for non-existing servers?

rustic oriole
potent lichen
#

Sometimes a JDBC url can be used with more than one driver. In this case, which driver is chosen depends on the specifics of the configuration and classloading at play.

wind dove
trail plume
#

no

#

that method just grabs the first player from the connected players list for that server and sends a packet over their connection

wind dove
#

could it be because the first server has 0 players online?

#

and it tries to send it to the first server with at least 1 player online?

#

...or could it be because I am sending it from inside a ServerSwitchEvent and it tries to send it through a player who may have already switched servers

#

actually I was wrong, the plugin message does not arrive twice, it just arrives at the wrong server

wind dove
trail plume
#

You need a cancellation server or whatever it was

#

they need to go somewhere

wind dove
#

so there's no way to prevent connections to a server without a cancellation server right?

trail plume
#

I mean, they need to be connected to something

#

if you want further understanding of the behavior, you'd need to look at the source code

wind dove
#

ok but isn't the event called before the new connection happens? (as it is cancellable)

trail plume
#

afaik yes

#

but idk what the logic for that event looks like

#

being frank, i'm highly out of tune with waterfall right now, and a lot of the event logic inside of bungee often rarely makes sense, especially around this stuff

wind dove
wind dove
#

it seems to be working now... maybe I should have tried it before - this does prevent me from connecting and does not throw any exception

image.png
onyx elm
# wind dove it seems to be working now... maybe I should have tried it before - this does pr...

isn't there a like ServerSwitchEvent that is intended for that type of functionality that you could use? Then you don't have to worry about where they go because you're cancelling the switch, meaning they should just stay where they already are. Be careful tho, as I'm pretty sure that event also fires when they initially connect in addition to whatever event fires only when they initially connect. Cancel a switch event when that situation occurs will actually disconnect them from the proxy. Also it's not ideal to mutate a cancelled event that you haven't uncancelled.

Is there any way to check if a player has played before on join?

#

on the proxy

barren cloud
#

perhaps i could connect to a plugin on one of the servers on the network and check

#

i wonder if anything could go wrong there tho

trail plume
#

basically, no; the proxy doesn't care about users and so doesn't store any info about them; the only thing that does is the "last server rejoin" thing

pure vale
#

Is there a way to disable the inbuild server command (override it with my server command)?

trail plume
#

I mean, you can just register your own command in place of it?

#

or just disable the module if its your own server

pure vale
#

I registered my own, but the default still uses the bungeecord one. I also tried to remove the jar from the modules dir but it gets redownloaded instantly

pure vale
trail plume
#

in the modules.yml or whatever it was

remove it from there and delete the jar iirc

Hey, is there a way to check if the proxy is fully loaded? Also all plugins loaded and so on. Like a ProxyReadyEvent

It's the PermissionFunction implementation correct?

When ip forwarding is enabled, UserConnection#getGamemode() always returns 0. This is probably because rewriting entries also reads and saves that data, but with ip forwarding the uuid already is online, so no rewriting/reading is done at all. Is this considered a won't-fix?

trail plume

Basically, idk if there exists any desire to change that stuff

idk why hes storing that

idk if there exists any desire to fix it, waterfall is a low priority given my potato pc and 200 other things on my todo list, but, if there was a PR idk if I'd be against pulling it

#

is there a way to tell when a player times out from the proxy? on the backend servers you can get the kick/quit reason and one of them is for being timed out, but I'm not seeing a way to tell that on waterfall

afaik no, that stuff isn't really tracked

is there an easy way to like read the logs to detect when it says they timed out there?

#

Short question - does waterfall have an option for loading defined maven libraries, like in spigot/paper plugins?

trail plume
#

Yes, spigot added it to bungee

boreal crown
#

It's meant to get a list of server names from the config, iterate through it to find a server that is online and has players and then use a random player from it for the connection...

#

I think some caching would help here reducing API calls, but I fear it might have some downsides in the end (i.e. server is removed before cache expires so entry holds now outdated info)

trail plume
#

For my own use case where I needed info, I just made the backend servers broadcast updates or whatever

hi guys, since spigot discord is dead all the time, I'm searching for a method that prevents serverconnectevent for firing if connection fails.

example
1.16 client wants to connect to 1.19 server with /server command, for some weird reasons even if the connection fails the event (serverconnectevent) gets called and i need to prevent it since after that the proxy itself will handle it as a kick

It's possible to see why an event gets cancelled?

depends, for debugging, there might be a plugin for it, idk; otherwise, modify the event class

for stuff in an actual plugin, no

#

it's like 5th time that i ask the same question.

why the hell is not possible to know IF the backend is fully started up

sleek jackal
#

becuase the server doesnt tell the proxy that

#

you can try to ping it but that won't tell you if it's fully started

#

only way is with your own plugin to my knowledge

hexed rune
#

i can't use channels since i need at least 1 player on spigot side

sleek jackal
#

then use something like redis

hexed rune
#

sockets are not an options since are so broken on backends

#

bloated

sleek jackal
#

lol

hexed rune
#

also too heavy for my server

sleek jackal
#

then another kind of message broker

hexed rune
#

like?

sleek jackal
#

#

rabbitmq, zeromq

brazen hamletBOT

#

but why should i use those libraries that are not meant for what i need

#

i just need to connect a player ONLY if the backend is on

#

latebind got removed idk for what kind of a reason

sleek jackal
#

then try to ping it

#

if it's true, it'll be online

#

if it's false its offline

hexed rune
#

it is not

#

returns true when says "starting mc server on ip:port"

#

that's so wrong

sleek jackal
#

then you're out of luck

hexed rune
#

i even tried boostrap

sleek jackal
#

use your own plugin or stop complaining

hexed rune
#

i'm trying to make my own plugin lol

#

that's why i'm here

sleek jackal
#

and I told you multiple solutions

hexed rune
#

but there is NO way to know if backend is online

sleek jackal
#

use your own message broker

#

onEnable() {
sendRedimessage("server1 online")
}

onRedisEvent(Event) {
if (event.getMessage().equals("server1 online") server1 = true:

# hexed rune but there is NO way to know if backend is online

Thing is, you have to define “online”
As soon as the server says “listening on port xyz” is IS online.
If you want to wait till all the plugins are loaded or something, you gotta make something custom that will look for all that shit, and then you need to message the proxy and let it know

trail plume
#

late bind was added many dozens of years ago to mitigate a bug

#

that bug was patched, and so spigot dropped the latebind patch given that with the bug being fixed, it made little sense to maintain that patch given all the bugs that that patch introduced itself

#

Now, you have 2 options

  1. restore late bind yourself
  2. Use one of the many dozen workarounds and solutions which people used for almost a decade, given that latebind sucked, successfully

use a message broker like they suggested and maintain a proxy-side list of online backends

send heartbeat messages every 30s on the backend and subscribe to those on the proxy and append to the list

remove from the list when the keepalive passes

this is how any run of the mill concurrent system works

Yea, I’m half confused on what they’re asking and so kinda just went back to dying

honest coral
honest coral
trail plume
#

see the javadocs, too dizzy to look

#

there should be events for joining/quitting the proxy

honest coral
#

I found PlayerDisconnectEvent, but nothing more

trail plume
#

and there should be login events

#

or use the server connect event and see if they're already on a server

honest coral
#

i'll use login event

#

login event doesn't have a getPlayer()

#

postloginevent

trail plume
#

well, yea, those events are early on in the connection lifecycle

#

the best one for having a player is probably going to be the server connected event and seeing if they have a current server or not

honest coral
#

I got it working

#

but now my player leave

@EventHandler
    public void onPlayerLeave(PlayerDisconnectEvent event) {
        ProxiedPlayer player = event.getPlayer();

        Main.getInstance().getProxy().getScheduler().schedule(Main.getInstance(), () -> {
            if (!player.isConnected()) {
                try {
                    if (Main.getInstance().isInGroupDB(player.getUniqueId().toString())) {
                        Main.getInstance().setLogged(player.getUniqueId().toString(), false);
                        Main.getInstance().removeGroup(player, Main.getInstance().getUserGroup(player.getUniqueId().toString()));
                    }
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }, 5, TimeUnit.MINUTES);
    }

now even if you come back the server it will "logout"

#

player.isConnected() doesnt work

vagrant prawn
#

@honest coral
A few things:

  • You don't have to (but you can, it's not wrong) get the proxy instance from main, there is ProxyServer.getInstance()
  • It's recommended to use a more descriptive name than Main
  • Giving the listener class the Main instance via constructor or making a Main plugin = Main.getInstance() variable would be nicer
  • What are "groupDB", "setLogged" and "removeGroup"?
  • You could check if ProxyServer#getPlayer(uuid) == null
  • Is there a reason you're toString()-ing the UUID?
  • does removeGroup need the player instance or would the UUID be enough?

Hi, how do i make it so only when they're fully loaded in then run the command:

    @EventHandler
        public void onPlayerJoin(PostLoginEvent event) {
            ProxiedPlayer player = event.getPlayer();

            TaskScheduler scheduler = ProxyServer.getInstance().getScheduler();
            scheduler.schedule(this, () -> {
                player.sendMessage(ChatMessageType.CHAT, TextComponent.fromLegacyText("Teleporting to lobby..."));
                player.connect(getProxy().getServerInfo("lobby"));
            }, 1,TimeUnit.SECONDS);
        }
#

Or is there a better way to teleport someone to the lobby when they join?

subtle radish
#

pretty sure you can override it ever sending them to a server that isnt the lobby in the first place when they join

bleak current
#

I know about the force default server thing but I can’t put that on because I want the player count to show all backend servers

trail plume
#

That's ping pass through

#

Otherwise, use a reconnection handler or whatever the API called it

potent lichen

Just to get this straight. The channel in PluginMessageEvent is called "tag"? Right?

trail plume

#

HI, for an inventory sync system. Is a good aproach?

On server join -> get the inventory in the db in base64 and apply.. On the server leave store it in a reds cache and get it in new server at on playerjoin ?

astral walrus
#

dont use base64, save NBT as bindata

trail plume
#

No, that's not a good idea

#

because you join the new server before you leave the old one

#

idk where the line sits exactly

astral walrus
#

its not an easy line

#

*to determine

#

back when I wrote my datasync plugin, i just ended up putting a delay

#

when you join a server it waits for a certain amount of time, and it was usually enough

#

something like 5 seconds

#

(heavy modpack)

viscid terrace
#

Is adventure embedded in waterfall?

potent lichen
#

No

bright imp
trail plume
#

read what we've said

potent lichen
#

Well, this is actually a good question: how do I synchronize player inventories across multiple servers in a reliable and fault-proof fashion? Adding a simple delay for loading the inventory may be a solution that works most of the time. But surely I can imagine extreme situations which break such an approach. Increasing the delay might help, but that reduces quality of gameplay.

trail plume
#

er

#

bahahahahahahaaaa

#

Basically, you'd need to be able to tell the server "i'm about to do a transfer, put the player into a limbo state"

#

and then basically save their inv, etc; tell the proxy you're done

#

and then do the actual transfer

#

until then, literally all you've got is some form of messaging maybe, and praying

potent lichen
#

It definitely requires proxy coordination. I suppose limbo servers could be useful for more than cracked networks.

trail plume
#

well, limbo servers would be one hack around

#

the issue is the expectation that if the connection to the new server fails, you're already in a server

bright imp
#

The new server

gusty swan
# potent lichen Well, this is actually a good question: how do I synchronize player inventories ...

First create a database with the inventory contents and a boolean value. Lets call it inSync

On disconnect save the players stuff in the db and after this (extrem important) set inSync to false to tell other servers that the data was saved so the other server can safely load it back.

On join make some kind of task thats wait with loading until isSync is false. If its false, set inSync to true and after this load your data.

This will prevent other servers from loading your data until the other server where you came from has fully saved your data.

You can also do the same with some kind of distributed locking. Like hazelcast (https://hazelcast.com/blog/long-live-distributed-locks/) or else

ive got some code that listens to the ServerSwitchEvent event and sends a plugin message to the server that the player joined and left. it works when there is another player in the server that is left but not when there is no one else in that server. when they leave a server with no other players in it then the plugin message is sent twice to the server they are joining somehow

player.getServer().sendData("BungeeCord", b.toByteArray()); // send to joined server
event.getFrom().sendData("BungeeCord", b.toByteArray()); // send to left server
frozen kelp
#

ended up just checking how many players were in the server being left to see if there was anyone in it

subtle radish
#

plugin messages are sent over a players connection between the proxy and the backend server. no players = no connection to send the message over

sharp apex
#

Can you do a blocking operation in the server connect event or would that block the whole waterfall thread?

trail plume
#

can't say without looking at code and such, but, generally, most bungee events block the network pipeline

Hey, I have a question about plugin messaging, when you want to send plugin message on paper, the second param is channel, on bungeecord I registered channel "staffprotect:channel", does this mean in spigot in second param I have to specify "staffprotect:channel" or "BungeeCord"?

trail plume

you'd use your own channel

sleek phoenix
#

so staffprotect channel

#

okay

thanks

wait, if I have on bungee and on spigot listeners for plugin message, shouldn't I do, staffprotect:bungee and staffprotect:spigot? Because server from this was sent, could receive this also

#

A question, why field self in Configuration (package .net.md_5.bungee.config) is not exposed?

#

as there is no getKeys(true) - for getting deeper

and they're youre channels, you can use the same name on either side or distinguish them

or anything else really

so apparently sending a plugin message in the ServerSwitchEvent breaks now on 1.20.2 :S

Aren't there any volunteers that could help with maintaining Waterfall as well?
It doesn't seem fair that someone with health issues is having to do so much

trail plume
#

Nobody on the team wants to deal with it

#

Hence why we declared it was going to be considered end of life at some point soon like a year or two ago

dense laurel
#

Ah, well it seems like there is still demand for it. I hope someone would still step up to the task

trail plume
#

at the end of the day, the cost benefits of waterfall makes 0 sense for me these days, and theres little inclination for us to onboard somebody for the sole sake of playing maintanance of a piece of software which just isn't worth the headache these days when the effort can be placed elsewhere for much better pay off

#

I'm generally done with waterfall and the ecosystem surrounding it

#

any sizable effort into the project generally ends up going to waste or just incurs an excess amount of effort to deal with the rot of the software, i.e. the months of back and forth trying to remove aspects like entity metadata rewriting to improve mod support given how md didn't wanna get rid of it, only for him to effectively neuter the system after he finally clicked on that maintaining that mess was not worth the headache; lack of effort from plugin devs to work with me over improving stuff to try to clean up the rot, etc, etc; it's just not worth the time, stress, effort, etc

dense laurel
#

I would have thought maintaining Waterfall would still have required less effort than reinventing the wheel with Velocity

trail plume
#

Well, no

#

I mean, if you wanna bastardise maintaining to the level of "leaving it to effectively rot in the corner", sure, maintaining waterfall is trivial

#

actually fixing the years worth of issues in the thing is an entire different story, especially with the lack of backing of the project

I'm trying to make a Waterfall plugin with an authentication system. I have a working one using Paper, not Waterfall, but I was wondering how I could do something similar to: java @EventHandler public void onMove(PlayerMoveEvent event) { if (Authentication.codes.containsKey(event.getPlayer().getUniqueId())) { event.setCancelled(true); } }

#

I guess I could make a paper plugin + waterfall plugin communicate with each other, but I would really like to have everything on the waterfall plugin

trail plume
#

The proxy doesn't know about anything going on with player movement, etc

#

You'd need to use a packet listener, and deal with a whole host of potential caveats, etc

frigid hazel
trail plume
#

No

frigid hazel
#

damn lol

#

I know I shouldn't do this, but I've got no idea where to begin. Is this something close (ChatGPT wrote it)? ```java
public class MoveListener {

private final Map<UUID, String> codes = new ConcurrentHashMap<>();
private final Plugin plugin;

public MoveListener(Plugin plugin) {
    this.plugin = plugin;
    registerPacketListener();
}

public void registerPacketListener() {
    ProtocolManager manager = ProtocolLibrary.getProtocolManager();
    manager.addPacketListener(new PacketAdapter(plugin, ListenerPriority.NORMAL, PacketType.Play.Client.POSITION) {
        @Override
        public void onPacketReceiving(PacketEvent event) {
            ProxiedPlayer player = plugin.getProxy().getPlayer(event.getPlayer().getUniqueId());
            if (player != null && codes.containsKey(player.getUniqueId())) {
                event.setCancelled(true);
            }
        }
    });
}

}```

#

If not, then I'll just use MySQL and have the proxy communicate with all the servers

trail plume
#

No

frigid hazel
#

Rip, okay. Communicating it is

trail plume
#
  1. ProtocolLib does not exist for waterfall/bungee, so, that one will obviously not work
#
  1. movement occurs on the client, and so you can't simply just cancel the movement packet
#
  1. what you're asking to do is an entire rabbit hole of concerns, i.e. you'd need to teleport the player back when they move, and so you're going to have to be able to get enough context to be able to do that
frigid hazel
#

yeahhh, that's not good

#

is MySQL the best way to communicate to paper plugins?

#

just have a bunch of queries to see if they're authenticated

Hello, i am taking questionnement about inventory sync. How i can make perfect inv sync (because join event is called before leave event) so i can do? Use message borker and when the player join a server wait message broker?

trail plume
#

the only "perfect" solution would be a lot of a stateful headache

#

put player in limbo, save their inv, do server switch

bright imp
#

ah when the player make a command to server switch/beofre server witch save inventory and after teleport it?

trail plume
#

yes

bright imp
#

so i have to use a custom server manager for all my server changement request? or i can use a bungee/waterfall event/tool to wait until it's ready for tp?

trail plume
#

idk anybody who has implemented the system I've suggested

#

the way the system works doesn't really permit taking over the control flow too well, so it would only work if you bothered to manage all server transfers yourself and all that

#

most just end up tryna mangle it by delaying work on the new server, mainly wall time based, and praying that the server has saved it in time

bright imp
#

i'have forget how that's work but just the proxy can transfert player betwwen server? (so spigot plugin can't?)

#

ah with plugin message maybe?

#

if is that i have to be sure that i manage all request for bungee changement and allow the player to send the plugin message after that i'hve save the inventory ?

#

ah yes i think to connect plugin send plugin message from the player's client and he send connect to proxy but if a plugin make send pluginmessage i can't knwo (please confirm) so i have to be sure that all plugin message conexion will be managed by my plugin (like this methode:

save inventory: when is good
send plugin message

but there are a risk if player'inventory got changee after inventory save?

frigid hazel
#

It's probably very basic, but I've tried a few things and can't figure it out hahaha

bright imp
frigid hazel
#

I think I just need a Server, not sure how to get that though

#

Perhaps I can do player.getServer()...

#

or is there a better way to predefine servers?

trail plume
#

if you want to get the server somebody is on in order to send a message to them then yea, that is how you'd get it

bright imp
trail plume
#

I mean, sending data to the player would send it to the player, and not the server they're connected to

bright imp
#

what is limb?

trail plume
#

i.e. remove them from the world

frigid hazel
#

I'm trying to do something like player.getServer().sendData()

Basically I need to send a request to the bungee, check if they're authenticated, if so, it sends True or something

bright imp
frigid hazel
#

this could be way too slow though :P

#

Would it be too slow? I need to cancel an event if they're not authenticated, like a move event or something like that

trail plume
#

or you represent that state using a boolean in whcih you message over the network

frigid hazel
#

Yeah, I think that's kinda what I'm thinking

trail plume
#

plugin messages are not transactional, etc

frigid hazel
#

then a bit of regex

bright imp
bright imp
trail plume
#

without modifactions to the server, no

bright imp
#

and for your limb I have to stop him from being able to interact with his inventory so what is the best way?

trail plume
#

I mean, there is no best way to do this

#

I don't know anybody who has dealt with this in the more "perfect" of manners

bright imp
#

do you know how most plugins work? or the most populate methode?

trail plume
#

as I said, they just wait for some period of time on the new server and pray that the data saved in time

bright imp
#

ah okay because on player leave i can get inventory but a simple problem with communciation and duplication bug.

I think i have to do it;

but you know if its possible to make a player inventory'iinvulnerable?

trail plume
#

No, it's not

#

hence why I keep saying limbo

#

but, there is a reason those plugins do the "just wait and pray that the data saved in time"

#

Some add some locking mechanism to try to reduce the risks, but, given the lack of a proper communication system, stuff gets screwy

#

Like, theres so many unsolved issues here, that really, glhf

frigid hazel
#

Hmm, what I'm thinking may not be the most effective way of doing it. I'll quickly go through what I'm thinking of doing.

I'm going to hook a Discord bot into the proxy plugin and handle the authentication command, codes, and all that in the proxy plugin. Everytime a user joins/moves, it will check to see if they're authenticated, if they are, it doesn't do anything. If they aren't authenticated, it cancels the event.

To check if they're authenticated, I was going to do a message from the spigot plugin with something like "Check: UUID" and to respond to that, I would do something like "True: UUID" (if authenticated).

I'm aware this would be much easier on just a lobby spigot plugin instead of network-wide, but I would like for the option to allow people to join any server they want, not through the lobby using subdomains. If it's not a feasible option, then I'll probably just revert back to what I had prior to trying to do this.

#

Keep in mind, authentication is only used by staff, so it's not going to be running for every single player

bright imp
#

what is the timeout-time for a client before give up login?

trail plume
#

you have like 30 seconds from connection to in the world, more or less

#

with a whole host of dozen caveats, etc

bright imp
trail plume
#

the client has to login

#

recieve chunks

#

respond to the keepalive packet in time or it gets dc'd, etc

bright imp
#

So using playerasyncprelogin event i have 20/30 sec to get the new inveotrh on the db ? (I check if the data is refreshed every 5 seconds and ar 25 i kick the player)

So there is this weird problem, when i cancel a ChatEvent proxy-sided, when the player the cancelled message was from sends another message they get kicked because of an invalid chat signature... any ideas on how to fix this?

trail plume
#

Basically, you can't

potent lichen
#

If you can't use Velocity, you'll have to adapt SignedVelocity to BungeeCord.

wicked lantern
#

I think its not proper say switch to velocity here. Probably he haves already build a sytem around it

trail plume
#

Not aware of any "similar stuff"

wicked lantern
wicked lantern
#

You must use redis i guess

#

It's a system that is used to store stuff on table hashes

#

If you don't know, probably you'd like to use some plugin that does this

wind dove
#

is it possible to choose the player used to send a plugin message to the backend servers?

trail plume
#

Doesn't the API expose the players server connection?

reef minnow
#

is the locale loaded (via ProxiedPlayer#getLocale) already present in the LoginEvent?

lean gobletBOT
#

I don't think so

#

afaik the player settings packet is only sent after the player joined the game

trail plume
#

No, LoginEvent is fired long before the client sends that info

#

in 1.20.2, it's sent before you join the world, before that, it's sent sometime after

reef minnow
#

it looks like it is loaded in the PostLoginEvent

lean gobletBOT
#

most likely only works in 1.20.2 if you care about older versions

reef minnow
#

is there a better event i could listen to?

#

idealy an async event

lean gobletBOT
#

aren't all events async on bungee/waterfall? or are they synced in a queue?

#

but SettingsChangedEvent would be the one

potent lichen
#

Not all are AsyncEvent in a way that enables the intention system. But I believe they are asynchronous in that sense.

lean gobletBOT
#

ah, right, I always forget about that system

potent lichen
#

The path to firing events from EventBus is unsychronized, so they could totally fire in parallel, I think.

lean gobletBOT
#

unfortunately the SettingsChangedEvent on bungee is extremely basic compared to other event APIs

reef minnow
#

is the first SettingsChangedEvent (on waterfall) called after the AsyncPlayerPreLoginEvent on the paper side?

trail plume
#

Yes, once again, far after login

#

pre 1.20.2, the client sends it just after you get the join game packet

#

1.20.2 sends it in the configuration phase, idk how md mapped that to existing events, my care for WF/Bungee is at all all time low, so, I never tracked that down

#

but, it's 100% not going to be tied to the login events

reef minnow
#

ah i see

soft scroll
#

Something that I found out: Why Paper's setPlayerProfile doesn't work if you are connected to the server via Waterfall? I'm trying to change a player's skin with it and, while the code works if I connect directly to the server or if I'm using Velocity, it doesn't work if I'm using Waterfall

This also doesn't work in BungeeCord, so this actually isn't a Waterfall issue but an upstream issue, but I was curious about why it doesn't work

(inb4 just use velocity instead of using waterfall lol, maybe this will convience me to migrate to Velocity once and for all)

trail plume
#

I mean

#

try disabling tab list rewriting in the waterfall config if you've not got it disabled already

soft scroll
#

the proxy also doesn't have any plugins

trail plume
#

No idea then

soft scroll
#

new reason to migrate to velocity just dropped!!! /j

trail plume
#

make sure metadata rewriting is disabled too

#

i guess

soft scroll
#

let me try

trail plume
#

it's generally down to some oddball desync between the identity somewhere

#

shits been going on for years

soft scroll
#

nope, also doesn't work

trail plume
#

glhf

soft scroll
#

tbh, considering that Waterfall is EOL (sort of)

#

I could migrate to Velocity (if I migrated all of my plugins)

trail plume
#

I mean, there comes a level of "somebody would need to look into what is going on"

#

chances are it's losing something somewhere or something is being rewritten

#

would need to see what bungee is doing

#

and, I generally have 0 inclination for that somebody being me

soft scroll
#

now it makes sense why those skin changer/restorer plugins need to be installed on Bungee/Waterfall level: it is because something somewhere in Bungee causes it to bork so they need to change the skin on the proxy level

#

because I was wondering about why tf these plugins do all sort of weird crazy stuff when you can just do player.setPlayerProfile

trail plume
#

Well, yea, there is a bunch of logic in bungee which has caused issues for years

#

disabling the tablist & entity metadata rewriting should disable most of that, but, eeeer

wind dove
trail plume
#

Eeeerrr

#

doesn't that send a packet to the player?

wind dove
#

I think so; I need a method to send a plugin message to one of the backend servers through a player's connection

trail plume
#

Yes, so, get the Server from the player and use that

wind dove
#

but doesn't that send the message through a random player? I need to choose which player to use to send the message

trail plume
#

No

wind dove
#

so even if two players are connected to the same server they will have two different Server instances?

trail plume
#

yes

wind dove
#

that makes sense then

languid lake
#

cat so smart

rustic rain
#

So I wrote a plugin to link up the "portals" of ancient cities in my survival server with previous seasons/versions of my survial so ppl can explore the previous seasons. However sometimes when players travel trough portals (or join the survival from the hub) they get kicked with the following message:

Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Packet 0/22 (PacketPlayInLook) was larger than I expected, found 16 bytes extra whilst reading packet 22

This only happens when using portals (and npc's for some reason), but not when using /server. Does anyone know what I did wrong?

This is the waterfall part of the plug-in: https://pastebin.com/DNQZarVX

nvm I updated waterfall and it seems to fix the issue, should have tested that beofre posting

rugged grove
#

is there a waterfall version that supports 1.8.8?

chilly coral
#

latest

wind dove
# trail plume Yes, so, get the Server from the player and use that

apparently the plugin messages are not always sent using this method; I started noticing it today but just because I wasn't able to test it out completely

the fact is that I need to send a plugin message just when a player disconnects and so I cannot use their connection to send it because they are no longer online.
so I tried the method you suggested using the Server instance of another player but it still does not always send it (or, better, it sends it but the Bukkit server never receives it)

trail plume
#

I mean, that logic has been buggy for years afaik

#

there is a reason why we generally suggest using anything but plugin messages if you wany reliable messaging

wind dove
#

I see, but I would avoid implementing a new messaging method for just a plugin message whose purpose is to send a message to a player (but I cannot do it directly from the proxy)
...isn't there any other method (not covered by API, maybe?) to choose which player to use to send the message? in this way the message should always arrive (I hope, at least)

trail plume
#

Yes, you literally get that player and use their server connection

#

the exact same as in the first place

#

There is no reliable mechanism for sending messages which isn't "go and actually use a reliable mechanism for sending messages"

Its a bungeecord bug, you cant really swap to servers with duplicated boards as far i know.

Try to make your plugins use different scoreboard names on same server

for now I will use the old version of waterfall

halcyon cargo
#

Hi! I want to create persistent bossbar using adventure, but when the player changes the server - bossbar disappears. I tried re-adding player to bossbar viewers in server connect events, nothing changed

#

Code is really simple - only bossbar initialisation and adding viewers to it

wicked lantern
#

Use switch event and set it again i guess

halcyon cargo
#

Yeah, the thing is switch event has method getFrom(), which i don't need in this case, but does not have something like getTo()

#

Maybe i can get the server player has connected using player#getServer

#

Because I want to exclude one server from displaying bossbar

#

Server connect event is also fired when changing server, but maybe that's not the good option for that

I have a problem with the ProxyConfig.java interface located in bungee.api:

I want to add a custom parameter to the config.
If I see this correctly, there are two configs: one from Waterfall itself (waterfall.yml) and the one from bungee.

My issue is that I need to read the property in the BungeeCord.java file.
There is a getConfig() method which returns an object from the ProxyConfig interface.

Which one?
There is the Configuration.java from bungee and the WaterfallConfiguration.java from (obviously) Waterfall.
Neither of them implement all the methods from the ProxyConfig interface.
Where should I put my custom config option?

The compiler currently nags me about this error:

[ERROR] /home/thorben/Dokumente/Development/Waterfall/Waterfall-Proxy/proxy/src/main/java/io/github/waterfallmc/waterfall/conf/WaterfallConfiguration.java:[10,8] io.github.waterfallmc.waterfall.conf.WaterfallConfiguration is not abstract and does not override abstract method isWaitingForPlayersEnabled() in net.md_5.bungee.api.ProxyConfig

I am unsure on how to proplery add a new config option.
I personally dont mind if its in the waterfall.yml or config.yml, however, the bungeecord class itself needs to be able to read this value.

subtle radish
#

are you trying to add a config option to bungeecord.yml or waterfall.yml?

#

if you are making a plugin, just use your own file

hollow path
#

I want to change the behaviour of the disconnect when the server closes.
It should wait until every player has left the server, so no one gets kicked while e.g. playing a game.

Via HAProxy I can dran the bungee proxies so no new connections get added, and all existing ones should not be terminated. The proxy should wait until thers no connections anymore.

I dont think I can cancel or override the end command of bungee with my own logic and stop the server arbitrarily via a plugin?

#

Therefore I want to edit the "independentThreadStop" method of bungee so it waits for shutdown until noone has connections over the proxy.

And to switch the behaviour, I want to add a new config option named "wait_for_player_disconnects" in either waterfall.yml or config.yml, though I think it fits best in waterfall.yml.

#

I also dont understand why the getTimeout, getUUID dont have any implementations, at least according to IntelliJ.
It complains that the WaterfallConfiguration.java doesnt implement the getTimeout() method, but Waterfall still compiles just fine?
Where does the implementation come from? DI?

trail plume
#

it's lombok

hollow path
#

Oh no

hollow path
# trail plume it's lombok

Could you help me though with adding the custom config parameter?

In which class should I implement it?

trail plume
#

No

#

it's pretty much at the point of basic java

#

define it in the interface, and define it in the config class that implements it

#

the waterfall class is there for reading from the waterfall config, the super is there for reading from config.yml

so if i already have texture and signature of player skin, how to set it for player

limber pecan
#

Are plugin messages safe to use. Like to send data between a server and a proxy, you need a player as middleman. Can't a player just generate its own pluginmessages and send that to the proxy?

languid lake
#

you can check the sender type

#

i.e. where it's coming from

limber pecan
#

I obviously don't know enough about this, but you mean it's not an issue?

languid lake
#

it's safe to use if you consider where the message is coming from

#

if you just want to communicate server <-> proxy but the message sender is a ProxiedPlayer then you'll want to discard it

limber pecan
#

Okay, so just do some instance checks...

But I don't understand how this can be achieved, doesn't the information have to go through a player to communicate between server and proxy?

languid lake
#

it uses the socket connection between the proxy and the server that the proxy is proxying for a client, but for that to exist a client has to be connected to the proxy; if it only stays between the server/proxy connection, it isn't sent to the client

limber pecan
#

Aha, that clears up my understanding. Thanks!

Yeah, I always thought the client was middleman, as the client is required.

languid lake
#

the proxy is the middleman, forwarding packets between server/client, but as it can intercept them you can do extra stuff with them as well before it gets forwarded

limber pecan
#

Oh... Yeah, true.

#

(I now remember this is exactly why I wasn't didn't think about this earlier on, as the proxy is the middleman it can modify malicious packets sent from client to server and so on)

#

how?

trail plume
#

outside of "reproduce without plugins", eeeer

#

I mean, looks like you're sending a message to a dead connection

stable river
#

how

#

if (p != null)

trail plume
#

that's not how that works

#

if you store a connection object and the player DCs, it doesn't magically turn into a null value

stable river
#

How do I fix it?

trail plume
#

well, are you storing old connection objects or not?

#

if yes, generally, don't do that; or, at the very least, check if they're still online

stable river
#

ye

#

online

trail plume
#

them still being in the list means effectively nothing

#

I have no idea how you're logic works

stable river
#

ok ty

# 
    public void removePlayerOffline(ProxiedPlayer player) {
        OfflinePlayers.removeIf(p -> p.getUniqueId().equals(player.getUniqueId()));
        members.removeIf(p -> p.getUniqueId().equals(player.getUniqueId()));
        members.add(player);
        if (owner.getUniqueId() == player.getUniqueId()){
            setOwner(player);
        }
        if (timePlayerOffline.containsKey(player.getUniqueId())) {
            timePlayerOffline.remove(player.getUniqueId()).cancel();
        }
    }
#

I think I fixed it.

#

ye fixed @trail plume

Known bungee cord issue

#

Literally all you can really do is endure that you don’t have duplicate team names across servers

timber lichen
trail plume
#

Scoreboards

timber lichen
#

permission ranks?

trail plume
#

Read the error

timber lichen
#

is that what you mean

#

?

trail plume
#

All I can do is point to the error

timber lichen
trail plume
#

You have a plugin in your server creating scoreboard teams

timber lichen
#

i have to give this a other name on every server

Fallback:
title: "&8<-&ao&8-> &bPromi&6Games &8<-&ao&8->"
lines:
- "&6Zeit:&f %localtime_time_HH:mm:ss%"
- "&r "
- "&6Rang:&f %vault_group%"
- "&r "
- "&6Clan:&f %simpleclans_clan_name%"
- "&r"
- "&6Online:&f %bungee_total%"
- "&r "
- "&6Sterne:&f %vault_eco_balance%"

?

#

so Fallback1 2 3

trail plume
#

That is causing issues with server transfers because they’re using duplicate team names across server instances

#

I cannot tell you what you have on your server that is breaking it outside of it being scoreboard related

#

All I can tell you is what the error means and point you to the name of the team that it is upset about

timber lichen
#

i rly dont now what team is mean

trail plume
#

It’s literally a Minecraft feature

#

The scoreboard commands

#

i cant even see the back to server list button

#

starts with

#

[Render thread/WARN]: Client disconnected with reason: Internal Exception: io.netty.handler.codec.DecoderException: net.minecraft.ResourceLocationException: Non [a-z0-9_.-] character in namespace of location:

#

then its a long ass component tostring

#

seems to be from a tab-related packet

#

?

#

why is the location a component?

#

Something is messing with packets and borking the data

#

Generally outdated plugins but Maoshrug

timber lichen
#

i use now citizens and i no longer have the issue

plucky lava
#

Yeah Im getting this for some reason

Screenshot_2024-02-05_at_9.28.33_PM.png
#

With these plugins

Screenshot_2024-02-05_at_9.28.53_PM.png
#

Proxy-1.0-SNAPSHOT does nothing with packets

#

And also if a player times out then for some reason they don't get disconnected from proxy which is weird

#

so they get a "already connected to this proxy"

Hii ! how to make a waterfall fork? i really want to make one.

What do you mean by "how to make a waterfall fork"

So.... How do I properly setup plugin messaging in BungeeCord with a custom channel identifier?
Like listen for incoming ones and sending own back?
There are no docs for BungeeCord that seem to cover the proxy side... Only the Server side.
