[frank meteor]

What package should I look in for researching this?

[lean goblet]

it's not really doable with just the API afaik

[frank meteor]

Explain yourself .w.

[lean goblet]

see BungeeTabListPlus basically xD

[trail plume]

He's not sure if the stuff you'd need to do it is exposed in the API

^^

[frank meteor]

No i mean like

why is he is a bot

[bleak current]

yo off topic but I am currently trying to switch from java to kotlin for plugin dev and I know kotlin basics but im completely lost on setting it up with my intellij/maven environment and workflow

could you point me in the direction of how to do that

[frank meteor]

Sure

Lets go to dms to not flood the channel

[bleak current]

understandable

[formal coral]

what build is suitable for 1.16.5?

[trail plume]

just use latest

[formal coral]

having weird connection issues lately

[trail plume]

and?

Pretty much nothing has changed with the networking stuff in time

I really doubt that using an unsupported version is gonna fix anything.

[random vector]

can getSocketAddress be casted to InetSocketAddress 100% of the time from ServerInfo? https://gyazo.com/82aefc292eb0bfc44e16e98f7f3d6877

[trail plume]

No

[bleak current]

cant you just get the info you need from the socket address object?

[random vector]

has no methods sadly

found out its only SocketAddress when its coming from a UNIX system, so for the most part playerwise itll be an inet

[bleak current]

so if it’s platform dependent maybe you could@handle the address separately based on the object type

[random vector]

yeah I have, shoulda updated that msg

thank you though

[bleak current]

sure np

[flint haven]

Help me

[trail plume]

X:

is that a network drive? if so, don't

Otherwise, i got no idea, make sure git is updated, etc, etc

[flint haven]

Could it be because I am building in Java 17?

[trail plume]

nothing to do with java there

[flint haven]

Git has just been updated and it is not a network drive, how can I fix this problem?

[trail plume]

If that's a modified version of waterfall, basically, 'good luck'

[flint haven]

How to build via PowerShell

[trail plume]

You'd need to work out how the patch broke

You can't build via powershell

basically, either you need to reclone the repo as something went wrong with it, or, I mean, I got no idea, easiest option is often to just resolve the patch issue

[trail plume]

can't clone in windows and then run in a *nix environment

[flint haven]

Tried to run on linux But again failure

[trail plume]

clone it in the environment you run it

[wide maple]

You could have fixed this error by reading it. The solution is on your screen. Do that and run the command again

[atomic kelp]

how does the scoreboard api and teams api work? using addTeam just seems like it stores it locally but never has it networked?

and the client doesn't show the team name when tabbing for /team modify

[lean goblet]

the /team command is from the Minecraft server, it's not influenced by the proxy

[atomic kelp]

yeah i know that, but i use it's tab predictions to see if the client knows about the team, cause im fairly certain it shows teams the client knows about

but idk that could just be me not knowing better

either way, does the scoreboard api actually do things?

[lean goblet]

not sure if that command actually shows the teams that the client knows but I would assume that the api is somewhat functional

[dry panther]

does the ServerConnectedEvent get fired everytime a player connects to a server, or only when the player makes an initial proxy connection ?

[bleak current]

every time a player connects to a server

[dry panther]

is there an event only for initial proxy connection ?

[bleak current]

PostLoginEvent

(or preloginevent)

[dry panther]

thanks

[lean goblet]

why not just get the UUID directly from the sender?

oh, it's a Connection, yeah check if it's a ProxiedPlayer and cast it

[wicked lantern]

Hey, what's the patch to make messages.properties enable when The proxy load?

[tawdry narwhal]

It's not a paper patch, it's upstream

[wicked lantern]

Well, im speaking about proxy

[wicked lantern]

Nope, BungeeCord just won't apply messages on default

I renember Waterfall did a patch or im bad.

[tawdry narwhal]

BungeeCord#reloadMessages does so

[wicked lantern]

I just think u don't understand me

[tawdry narwhal]

That may be better

[gusty dove]

Hello, I am trying to use plugin message channels to get the server name from waterfall, I am using the bungeecord:main channel and the GetServer subchannel, but I never receive any messages back/ my onPluginMessageReceived method is never called, would anyone be able to help me with what I am doing wrong?

[wide maple]

Show your receive method?

[gusty dove]

The Breakpoint never gets hit on the first line

[wide maple]

Equals bungee channel name

Ignore case I’m pretty sure it’s stupid like that

[wide maple]

Also I think there is an event for this you could use an event handler and the PluginMessageEvent and see if that works

[gusty dove]

I will try that thank you

[wide maple]

Cat correct me if I’m wrong but I remember there being a bug in the namespaced:key format that caused issues here

[gusty dove]

The ignore case and event handler did not work

[junior chasm]

this is going to be a very stupid question.... ofc then again i am new to coding so i have a lot of them compared to a pro. If a plugin uses the waterfall api, will it still work with bungeecord plugins?

ie

<dependency>
    <groupId>io.github.waterfallmc</groupId>
    <artifactId>waterfall-api</artifactId>
    <version>1.17-R0.1-SNAPSHOT</version>
    <scope>provided</scope>
</dependency>

Instead of:

        <dependency>
            <groupId>net.md-5</groupId>
            <artifactId>bungeecord-api</artifactId>
            <version>1.17-R0.1-SNAPSHOT</version>
            <scope>provided</scope>
        </dependency>

you see, the net.md-5.bungeecord-api repo is not yet updated to 1.17.... you folks seem to be faster at that. We use waterfall anyway but the issue i ran into with this is that since the bungeecord-api repo is still for 1.16 and yours isnt, i had to basically make a backdoor and create a libs folder with the latest waterfall.jar in it. Which, turns out, causes issues when uploading to github as there are too many files. So if i can make it work for 1.17 the correct way (as seen above) then that will remove a ton of files thus limiting the data size for github

i am

does it work that way for private organizations?

(the other reason is a more personal preference one... that is to say the way this is currently done is janky af lmao if changing the dependency in the pom.xml as seen above will clean it up a bit while leaving it fully functional as it is now then that is what i want to do)

Does it matter if i have over 100 files if i upload it that way?

ok

ok so basically leaving it the way it is now in the pom.xml will allow both bungeecord and waterfall users to use the plugin but my way will only limit it to waterfall users.... right?

that's what i thought... but i need to find another repo that has the 1.17.1R01 snapshot api version on it that is not part of the maven repo.... since that last one only goes up to 1.16 mc

that way i can get it to work in the pom.xml

thanks!

[trail plume]

You can use waterfalls API on bungee so long as you don't use any waterfall specific API

Im trying to make a custom reconnect handler.

    val onlinePlayers = HashMap<UUID,ServerInfo>()
    init {
        ProxyServer.getInstance().reconnectHandler = this
    }
    override fun getServer(player: ProxiedPlayer): ServerInfo? {
        if(!player.isStaff()&&Config.maintanence){
            player.disconnect(ComponentBuilder(ChatHelper.format("&cServer is in maintanence mode!")).currentComponent)
            return null
        }
        val server = main.serverHandler.getHub()
        if(server==null){
            player.disconnect(ComponentBuilder(ChatHelper.format("&cNo hubs online!")).currentComponent)
            return null
        }
        onlinePlayers[player.uniqueId] = server
        println("Player ${player.displayName} is being sent to hub: ${server.name}")
        return server
    }

    override fun setServer(p0: ProxiedPlayer?) {
    }

    override fun save() {
    }

    override fun close() {
    }

    @EventHandler
    fun onDisconnect(event: PlayerDisconnectEvent) {
        onlinePlayers.remove(event.player.uniqueId)
    }
}

But for some reason when a player gets disconnected in the get server it still shows their join and leave messages

[trail plume]

that's from the actual servers themselves, you'd need a plugin on the servers to disable those messages

[frank meteor]

But why is the message sending when im disconnecting the player b4 they get sent to a server

[trail plume]

don't mention

[frank meteor]

mb

[trail plume]

they're still connected to the server they switch from until later on

[frank meteor]

will the login event still be called, if so how can i differentiate from a player thats about to be dced by the proxy and a player that can connect

[trail plume]

the reconnect handler is also only used on initial connections to the proxy, so that thing makes little sense

[frank meteor]

What should I use instead?

[trail plume]

the server doesn't know if the player is connecting from a fresh join or a from a server transfer

oh, wait, i misreadwhat you where doing there

I mean, that things only used on initial connections so you should never have an online player who has a server already assigned to them when that code is called

[frank meteor]

So the join/leave messages shouldn't be sending?

[trail plume]

the leave/join messages are still irrelevant to that

You'd need to stop those on the server itself

if you still want global leave/join messages best to just do that on the proxy itself

[frank meteor]

And is there any way to differentiate between a player login event thats real vs one that has a player thats gonna be dced

[trail plume]

I mean, you could send a plugin message to the server before you disconnect them to tell the server that the dc is gonna be a switch, but, otherwise, no

well, I mean, for login, sanely, no

[frank meteor]

I assume the message would send after the login event.

I guess i could just do it the other way and tell the server to send the join message when its valid

[alpine stag]

any recommended .SH presets for running a waterfall instance?

a template or something

[trail plume]

pins in -help.

[alpine stag]

thanks homie

[marsh furnace]

How would I transfer a proxied player to an external server (not on the proxy) such as Hypixel.net? I don't need them to remain on proxy

[trail plume]

you can't

[wide maple]

That will only work if the server you’re trying to send the player to is in offline mode

You can’t make the client authenticate again

[warm pagoda]

is there an event that picks up on the player logging into a server theyre being kick-redirected to? AsyncPlayerPreLoginEvent doesn't seem to fire on the target server we're sending them to

[trail plume]

server connect or something

I mean, if they're kicked to a server which they're not already connect to, then the server will go through the login process; The server they tried to connect to will fire whever events it will fire until they're kicked from it

[zinc falcon]

Howdy folks, looking to do something a little bit screwy. How possible is it to take a connection to one's waterfall and pass it on to a paper sub-server but with a different username/uuid? Ideally triggering paper to think of them as a completely unique user for usage in local plugins, inventory, location, etc? Allowing users to have multiple 'accounts' as it were. From what I can find online no-one is really trying this as of yet, any ideas other than just forking a copy of Waterfall?

[wide maple]

That’s a bad idea for one reason mainly:
If the UUID the server uses to refer to the player isn’t the same as the player got assigned during login then game features will start to break. Bungeecord has a feature that may allow to partially fix this but I highly advise against it.

Otherwise it’s easily possible

But also very unsupported

[zinc falcon]

When it refers to it where? In the paper server, or in the bungee/waterfall side?

[wide maple]

When you log into a server (or bungee in this case) it will tell the client a name and UUID
Both those are normally what mojang assigns you but they don’t have to be

The server ideally knows you by the same UUID/name

If the UUID the server knows for you doesn’t match the UUID you have been assigned then things start breaking:
Including but not limited to: Skins, teleporting, sounds, entities around you, certain gamemodes, certain abilities, certain commands and so on

This is why disabling info forwarding partially bugs your game

On bungee it only happens partially because bungee hacks the player list to fix a few of these issues

[zinc falcon]

And I assume there's no way to tell the client you've changed their username/uuid?

[wide maple]

No. After that’s been set it’s final. You can’t re-set it till you disconnect and connect again.

[hybrid vine]

I assume a plugin like FastLogin does some fuckery behind the scenes to change your UUID to UUIDv4 if you've got an account in minecraft.net

I'm not sure how that can help you but yeah

[lean goblet]

iirc you can achieve the same with waterfall events without doing some internal changes

[grand goblet]

how does one come up with plugin ideas?

[lean goblet]

easiest is to run a server and can't find proper plugins to do what you want

[grand goblet]

hmm, okay, thanks

[alpine stag]

setting up waterfall network. connected the first server working alright, but that servers console is unaware of the bungeecord commands

any bungee command like "/send player server" just returns "unknown command". i had this set up before and working like a year back, but i forgot how 😄

[wide maple]

you need a plugin for that.

the bungee commands are only available to the players when they connect through bungee

anything else requires plugins

[alpine stag]

thank you. almost figured that i was lacking a plugin. at any rate i dont remember which one i mustve been using back then - any recommendations?

and i take it that its normal for me not to have permission to use the bungee commands as a player despite being op? (since im not gonna bother use username-based permissions in the bungee config)

[wide maple]

bungeecord has its own permission system that doesnt have a concept of "operators". To manage it I would recommend installing a permissions plugin like LuckPerms on the bungee

[alpine stag]

thank you. and do you have any recommendations for said plugin?

im struggling to find any that do such a thing

[wanton tapir]

okay u have luckperms bungee version in ur bungee plugin folder correct

if so do /lp edit in the console on the proxy it will give u a link that link is a online menu to help setup ur ranks and perms more easy

now u also want a data base if u have a vps etc u can make one database will be needed to share the data global aka across all ur servers

[alpine stag]

is there no maven repo for waterfall?

[lean goblet]

it's in the paper repo

[alpine stag]

thank you

[alpine stag]

is there something extra i would have to add to them pom ? it's the first time im using maven. the paper stuff is working just fine, but expected to get the waterfall things aswell after what you said and its not there

https://i.gyazo.com/ce408db3281a8b4fddf376582fb88038.png

oh i think i found it <dependency> <groupId>io.github.waterfallmc</groupId> <artifactId>waterfall-api</artifactId> <version>1.17-R0.1-SNAPSHOT</version> <scope>provided</scope> </dependency>

for some reason some classes are missing though

https://i.gyazo.com/c500fdbcdb2bae5610233f876d3f360a.png

😐

[lean goblet]

that's not part of the API

[alpine stag]

it worked before when i was using the compiled jar as a dependency, do i need to add something extra?

a bungee maven repo or something?

[lean goblet]

non-api artifacts are not distributed via the repos as they shouldn't be used by plugins, use the API

[alpine stag]

hm okay fair i guess

(commandSender instanceof ConsoleCommandSender) this is where i was using that, i cant find a replacement for it though

[lean goblet]

just check if the sender is a player if you need to know that, anything else doesn't really matter anyways

[timber vapor]

ProxyServer.getConsole(); or ProxyServer.getInstance().getConsole();

don't know the exact object it returns right now, but it's easy to find out

[warm pagoda]

has anything changed with waterfall between 1.16.5 -> 1.17.1 that would make the ServerConnectEvent fire twice?

[bleak current]

@heavy sinew you are the author of automatic server reconnect?

[simple sage]

Hello, I have a question.

I'm trying to make a plugin that gets ban related data from mysql from the plugin when a player connects in 'bungeecord' and blocks the player's access before being switched to the server.

But what I am worried about is that the blocking that occurs when retrieving data from mysql causes delays in other players' access or problems.

Does anyone know of a solution for this?

[trail plume]

that's what the "Async" events are for

[simple sage]

I tried to refer to other open sources that implemented this before asking the question, but it was difficult for me to figure out the principle due to the complex structure of the source code.

[simple sage]

Wouldn't everything that works on async events block the netty or work thread?

[trail plume]

.g waterfall javadocs AsyncEvent

[lean goblet]

(DiscordBot) https://papermc.io/javadocs/waterfall/1.17/net/md_5/bungee/api/event/AsyncEvent.html

[trail plume]

Don't mention

The idea is that you go off to another thread and complete the event when you're done

[simple sage]

ok, thx

[wide maple]

fair warning, if you make the player wait to long the player will time out

In other things

[simple sage]

So, while delaying in one event is there no negative impact on the rest of the players?

[trail plume]

with the async events, correct

Just be warned that the client doesn't like waiting there for too long

[wide maple]

Depends on the event; but this event has only an effect on the target player. Effect being that if you wait for too long they time out

[simple sage]

Thanks for your kind reply. If you have a simple code example, could you show it?

It's fine without it.

[trail plume]

you call registerIntent on the event in your event handler

go run off and do your work on another thread, and then call completeIntent or whatever it was on the event

[simple sage]

thank you

[bleak current]

is there like

a resource pack event i cant find one

[trail plume]

no

[bleak current]

do u know if there's a way between paper or waterfall to not send the resource pack to a player if the resource pack from the server they're being sent to has the same resource pack as the server they're coming from

[lean goblet]

Well, no, the server doesn't know that

pretty sure that's what part of the hash is there to resolve

1. your code on the repo doesn't like up

2. anyways, you hit the end of the data stream and tried to keep reading

[ionic inlet]

I see that now, let me diff see if that makes a difference

[ionic inlet]

the function seems to function normally the rest of the time and I don't know why it only happens at this message

consistently

[trail plume]

You hit the end of the stream

whatever data you're tryna read is not formatted how you think it is

version mismatch? I mean, given that the code doesn't like up to the stack trace shows that the code that's on the repo is not what's running

[ionic inlet]

I ran a diff it does indeed differ a bit, but unfortunately not in the parts that matter. I guess I'm going to try decode it as much as I understand and see if readUTF instead of short helps or maybe check if its unsigned. Or if I can skip over this once in a rare occurrence by checking if there's something in "in" left to read.

Just annoying it only happens after SetPerWarpFlag which is a message by some other plugin.

Thanks for your help!

I'm diving in

[ionic inlet]

"fixed" it (not really) by returning the function when the subchannel is SetPerWarpFlag

[lean goblet]

I mean... one shouldn't read channels of other plugins to begin with 👀

[lucid jasper]

is there a way to get the tps of a paper server via the proxy?

[trail plume]

built in? no

otherwise? you can do whatever you want with plugin messaging channels, etc

[lucid jasper]

what do you mean?

[trail plume]

what?

It's data?

Waterfall doesn't have an automatic way to get the TPS of a server, it doesn't know, it's not told that

[lucid jasper]

no. what are plugin messaging channels?

[trail plume]

Google

The bungee wiki has a set of tutorials over how to use them, etc

[lucid jasper]

okay thanks

[humble hull]

is there a way to have bungeecord/waterfall hexcolors? without plugin messages?

[trail plume]

wat?

[humble hull]

like sending hexcolor with bungeecord messages

[trail plume]

yea

it's just components

[humble hull]

but its only possible for the whole message not only for one word in example

[trail plume]

I'd heavily suggest learning how components actually work

you can nest components to affect formatting, coloring, etc

[cursive wasp]

In case you didn't know for today, the protocol number for 1.18.0 is 757

[simple sage]

Is there any way to get the offline user's uuid from bungeecord?

[wide maple]

Not without using the usercache or querying the mojang api

[lone wagon]

I guess you could manually script a sync of the playerdata, not 100% sure how to do it off the top of my head, but I've done dumber things...

[round current]

Is there any way to store datas used in multiple servers?

[ruby python]

it depends

config file, yes by using a plain file
data of players ? By using a database

[proper nexus]

How do I get the backend server name the player is currently on and put it here?

DefinedPacket.writeString( bungee.getName() + " <- " + serverBrand, brand ); // server instead of brand```

[lean goblet]

there's nothing special about that tbh

generally speaking removing credit is a bit frowned upon though

[proper nexus]

damn it

if I do server name (brand)

?

[lean goblet]

I mean it's your server, you can do whatever you want

[proper nexus]

yeah, but how do I do it

[proper nexus]

anyone?

question about waterfall/bungeecord: where should I start looking for how to let people message/tpa/talk to eachother from different servers and show up in TAB?

So say person A and B are on servers 1 and 2 respectively, how can I have person B show up in person's A playerlist when they press TAB, or that person B can see what person A says between servers

would plugin messaging channels suit my need?

[lean goblet]

yes

[wide maple]

Wtf no?

[novel wedge]

Why not?

[wide maple]

That can all be done on the proxy with the api;
You’ll still need a plugin with the plugin channel downstream to enable the correct coordinate teleportations

[novel wedge]

So pressing TAB could show all players on all connected servers using the proxy api?

[trail plume]

I don't think that's covered in the API

oh, wait, maybe it can with the tab list api stuff in there

forget how BTLP does it exactly

[novel wedge]

So whenever someone requests the tablist, I should send a request to every server through bungeecord what players they have online?

[trail plume]

you don't "request" the tab list

the server sends it to you

the proxy has some mechanism in the API for toying with that stuff iirc as there was an old bungee feature which did that in the past

[novel wedge]

hmmm, I'll search around some more then, thanks for the nudge in the right direction

[bleak current]

Hey, wondering if anyone has a good alternative to BungeeCord Messaging Service for custom plugin messages?

[trail plume]

easy to just use the bungee channel and use a custom thing instead of the one on the page

otherwise, it gets more fun...

[bleak current]

Yeah, looking for the more fun stuff where a player doesn't need to be online ahah. Rn I'm looking at DeltaRedis on GitHub, but not sure if I'm missing an obviously good alternative

[lean goblet]

https://github.com/Phoenix616/ConnectorPlugin 👀

really depends on what you need and want what the best solution is though

[bleak current]

That would be what I'm obviously missing 😄

[lean goblet]

(although I doubt any basic solution would really break/need an update ¯_(ツ)_/¯)

[bleak current]

So a few use cases.

1. Data tracking, i.e. plugin stores player has key: variable, then player swaps server, I want the server they swap to to receive that data too. (Aware PlayerQuitEvent is called post JoinEvent) Data is updated too often to justify pushing to db each update

2. Cross-server teleportation. Player on server1 teleports to location on server2, we need to tell server2 they are teleporting to them co-ords

[violet saffron]

https://github.com/egg82/Messenger might be an option

[lean goblet]

well my solution has a couple of utility functionality like teleporting built-in

hard coding Rabbit smh

[bleak current]

Lol amazing, thank you so much all!

[lean goblet]

Messenger has some interesting concepts though, probably gonna improve my solution with some of those ideas

although I'm not sure if queueing packets should be global or based on the messenger method

e.g. I would hope redis can handle messages properly on its own without requiring queueing

and I should probably also do packet versioning 👀

[bleak current]

Hey, does the teleport function of ConnectorPlugin work on Plugin Messages if the target server has no online player?

[lean goblet]

it works but not as good

(like the player will be teleported after they logged in instead of changing their spawn location)

[bleak current]

Would you recommend Redis or Rabbit? Both look like they get the job done of allowing cross-server data communication. We've got a dedi but no one who's got experience setting up redis/rabbit, so if one is easier we'll probably go with that

[lean goblet]

well I personally only have used redis but if you don't ever need their key-value storage then a pure mqtt server is probably the better choice

but lots of stuff can use redis over mqtt or RabbitMQ

[bleak current]

Would Redis be the more sustainable solution for the cross-server teleport & saving player data while they're online on the network and swapping servers often?

[lean goblet]

(also the MQTT stuff is untested in ConnectorPlugin, I should probably put that somewhere lol)

[bleak current]

I feel like Redis is what we should go with for the use cases, just wanna double check 😂

[lean goblet]

both redis and mqtt have all features, there's no difference between them

[bleak current]

I've seen more MC plugins mention Redis than MQTT so I'll go with redis. Now to learn how to set it up, nice one very much for the help lol, just saved hours of my life

[lean goblet]

MQTT is a communication standard for IOT devices, seeing as RabbitMQ supports it natively I decided to just use a library that supports all possible MQTT servers ¯_(ツ)_/¯

(rather than depending on specific pubsub servers)

[bleak current]

Thank you

I just want to double check I'm not causing an xyproblem before I go too far.

I want to store "CustomData: 1" and "MoreCustomData: 5", essentially I want to store key-value data for every player. The data is loaded really often for every player, e.g. used for in-chat placeholders when you hover over their name, so it's queried often. It could be updated up to 6 times a second or once every 30 minutes and anywhere in between. Expected player count on average is ~20, but want to be able to handle up to 100 ish preferably

I want players to be able to swap servers on a Waterfall network and their data load quickly.

My current thought process is:

• Player Join server on network
• Load data from SQL, push to Redis
• Every time they data is updated, push to redis (anywhere from 6 times a second per user to 30 minutes per user)
• Player joins server on network, queries Redis, loads
• Player quits network or X time passed since last update -> push redis to SQL, clear from redis

Alternative is have the data stored on the proxy, and use netty/plugin messaging instead of Redis

[lean goblet]

I mean yes, you can use redis as a distributed cache but you could also just store and keep the data directly in redis

this doesn't sound like sending data via messages/packets in a pubsub system though

Hello! How can i use waterfall w/Maven?

<dependency>
<groupId>io.github.waterfallmc</groupId>
<artifactId>waterfall-api</artifactId>
<version>1.16-R0.4-SNAPSHOT</version>
<scope>provided</scope>
</dependency>

This should work?

[lean goblet]

https://github.com/PaperMC/Waterfall/#how-to-plugin-developers

[dusk heart]

thx

but how i use 1.18?

[lean goblet]

put in 1.18?

[dusk heart]

1.18-R0.1-SNAPSHOT?

[lean goblet]

pretty sure it uses a versioned scheme now though, check the repo for the correct one I guess. don't know it of the top of my head but the API really didn't change anyways

if it works, yes?

[dusk heart]

?

i'm trying

[wicked lantern]

@dusk heart What's happening

[ocean sand]

sting for 1.12.2 paper for fix exploit?

[dusk heart]

?

[bleak current]

this bungee update good

exposing the bad plugins

Plugin listener de.staticred.discordbot.bungeeevents.PostLoginEvent took 551ms to process event PostLoginEvent(player=Zooper)!

[near tinsel]

is there a way to get a player's protocol version with the 1.18 api?

[pastel hill]

[somber prism]

you need to make a commit, and then rebuild patches

i'd assume ./waterfall rb

[pastel hill]

One message removed from a suspended account.

[somber prism]

with your changes, yes. In Waterfall-Proxy

[pastel hill]

One message removed from a suspended account.

[pastel hill]

One message removed from a suspended account.

[trail plume]

yes, or just build with maven

[pastel hill]

One message removed from a suspended account.

[lean goblet]

did it correctly create a patch after the rebuild step?

[trail plume]

if your changes disappear you'remissing something

make sure that you actually added files, etc

[flint haven]

I want to build a waterfall with my patch, but I get this error in the screenshot what should I do?

[lean goblet]

your patch points to a non-existing commit hash

iirc

[flint haven]

And how to fix this problem?

[lean goblet]

how exactly did you create the patch?

[flint haven]

I can throw you a patch if it is required

[lean goblet]

just answering the question could go a long way

[flint haven]

need it?

[flint haven]

I didn't understand a little

[wide maple]

Essentially your changes to the Pom.xml are now conflicting because the file was changed in a patch before this one

[balmy perch]

Hey, i m a newcomer and i m wondering how can i use the bungee logger

Similiar to the bukkit.getlogger() method

I did not find such a method in bungee api, so i come for some help xd

[trail plume]

Wat

The bukkit logger is not your logger...

Use the one given to you by your plugins main class ...

[sterile stirrup]

Hello. I need help with helpop command. I have low-level experience with plugin development and absolutely 0 experience with bungeecord plugin coding. Can someone tell me how does bungeecord plugins actually work? Do i need both of bungee plugin and spigot plugin?

My point is to make plugin that allows members use /helpop <message> command in survival and it sends the helpop message to discord channel with webhook (I have done that and it works) and it also sends the helpop message to the survival chat for the staff members + it sends message to other servers too.

I dont know how to do it, i have been thinking and trying almost like a 8hours and i just cant figure it out...
Like i said, i dont know ANYTHING about bungeecord plugin development and very little about spigot development so please dont yell at me when i dont understand something lmao.

If i have to use both of bungeecord and spigot plugin, then how do i connect them? I have a lot of more questions.

Also sorry for bad english

[trail plume]

they work the exact same as bukkit plugins

Just, they run on the proxy

[sterile stirrup]

Okay

[trail plume]

you only need a spigot and a bungee plugin if you need to share data between the two things

[sterile stirrup]

What do you mean with data?

What data

[trail plume]

like, data, data

idk what data you'd specifically need to transfer

depends on what you meab by "survival"

[sterile stirrup]

survival server

[trail plume]

I mean, if it's just a server on the network, you could easily do it as a bukkit plugin

[sterile stirrup]

Okay

But how do i send a message to other servers?

[trail plume]

plugin messaging channel

[sterile stirrup]

never heard of that

Do you have any examples?

[trail plume]

the spigot wiki has a bunch of examples

[sterile stirrup]

with fast google research i found that: https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/

[trail plume]

yes

theres also many plugins out there which use messaging channels for sending data around, etc

[sterile stirrup]

So um.. i dont understand.. I need to use plugin messaging channel but how do i check for players permission in every server and then send the message to right players

[trail plume]

sanely? you don't

ideally for stuff like that you use luckperms to sync perms across the network

they're two seperate pieces of software

the proxy cannot access data on the server, the server cannot access data on the proxy

You can use messsaging to send info around the place as you desire, but, theres no transaction system, etc; you can't "ask" for data and wait for it without complex setups, and, it's generally not worth it

if you don't specifically need anything on the proxy, theres already a communication channel setup for shooting messages around the network if you so desire

[sterile stirrup]

So i cant send helpop message to other staff members who are in the other server?

[trail plume]

Never said or implied that you can't?

You can literally send whatever the heck you want around your own network

if you just want a /helpop command, theres pretty much 0 reason, with LuckPerms, that you couldn't just do the entire thing on the proxy though unless you had specific requirements

e.g. they've gotta be in a specific world on the server to use it

[quaint topaz]

how can i edit waterfall i can't do it from intellij

I can't run it in intellij it gives an error

[limber berry]

what error

[quaint topaz]

how can i convert java

[trail plume]

Read the readme.

[quaint topaz]

I couldnt learn

[trail plume]

don't mention

run the script it tells you to run

if you run a build, it will setup all of the sources and compile

contrib guide has more info

you're gonna need to learn how to use the scripts to work with waterfall

[trail plume]

from bash

powershell is not bash.

[sterile stirrup]

okay. ugh, i dont get it. Only requirment i have is if player has permission... I want to send message to only players who has the permission. And no matters what server they are playing on. Literally the only thing i need... But i dont undestand how i still do it... How do i check permissions in all network servers and then send the message to all network servers. I have atm 4 servers total. Hub, Survival, KitPvP and SkyBlock. Of course i have waterfall too. Now all staff members should get notification when player executes /helpop command, no matters what server staff member is playing.

[bleak current]

Third one

[trail plume]

Once again

use luckperms

[sterile stirrup]

i use..

[trail plume]

luckperms literally lets you query permissions however you want

[sterile stirrup]

But how i check perms in all servers

[trail plume]

tf do you mean by "all servers"

[quaint topaz]

I did not understand anything

[sterile stirrup]

in survival, kitpvp, skyblock and hub at the same moment

[trail plume]

So

that's just global perms

nothing special there

unless you're actually doing weird stuff there, in which you'd probs need to do 4 permission checks

[sterile stirrup]

ya but how i specify the server what im checking....

[trail plume]

read the docs for luckperms

[sterile stirrup]

okay

[bleak current]

contributing.md is literally unreadable, smh my head

[trail plume]

people hardly ever look at that thing

I mean, I guess people do look at it from time to time, but, it's "basic" git below it all

[quaint topaz]

please help me i couldn't install

[quaint topaz]

it asks how do you want to open the file

[trail plume]

Do not ping.

open a bash prompt

run the script, literally as it says

[quaint topaz]

i try it gives error

[sterile stirrup]

i read the luckperms api usage wiki and didnt found how i check perms in specific server. Can you send link or something please?

[trail plume]

the LP api wiki tells you how to use contexts

of which you'd use contexts to specify the server, basically

there is much documentation on their wiki and they have a discord

[trail plume]

1. clone the repo

2. Read It tells you you don't have maven installed

[quaint topaz]

from which file can i change the commands

[bleak current]

which commands

[quaint topaz]

/restart

[trail plume]

well

there is no restart command

[quaint topaz]

/server

[trail plume]

and restart would be dumb as that would interfere with the servers version of that command

take a look at CommandServer or whatever it was called

I mean, if you're just replacing commands, write a plugin

[quaint topaz]

I know other commands /send /alert /server

[quaint topaz]

so how do i get it as a jar

[wide maple]

compile the project and the submodules for those respectively contain the jars

[quaint topaz]

There are texts written in green, can I update them all?

[wide maple]

You could just have put a modified message.properties in your proxy folder if messages are all you need to change

[balmy perch]

oh... By the way is there any methods better than sout to print debug messages?

[trail plume]

don't mention

[balmy perch]

And could you plz tell me the name of that method...

[trail plume]

well, theres the logger, but, setting up debug levels to actually log is a pita often

but, can be done

[balmy perch]

😭

Sry for that

I m new to Java and new to Bungee, so plz forgive if I have asked any silly questions🥺

[quaint topaz]

how can I get it as a jar

[wide maple]

get what as a jar? https://papermc.io otherwise

[quaint topaz]

i have built the open source code but how do i jar it

[wide maple]

?? the jar will be under bootstrap if I am not mistaken

[quaint topaz]

I can't import .jar as jar

[trail plume]

er

wat

literally run mvn package

the jar will be in the -Proxy/bootstrap/target folder

[quaint topaz]

I can't run mvn

[trail plume]

Don't mention

"i can't" gives 0 info

if you don't have it installed on your system, use the maven tool window

otherwise, install maven on your system.

[trail plume]

wat

I told you to do one of two things

you just sent a random useless screenshot?

At this point, I can't help you

[quaint topaz]

How difficult are your projects?

[wide maple]

if you’re on windows you need to have maven in your path

[quaint topaz]

I can't do it

because i've never done it before

[wide maple]

all I can say is that you want to run the maven goal ‚build‘ from waterfall-parent

[wide maple]

and that is the pom.xml from the Bungeecord folder. Don’t use that

you edit sources in the Waterfall-Proxy folder and nothing else

[quaint topaz]

Which command should we type?

[wide maple]

are you using intellij ?

you can run the maven goal build from IJ, just click maven in the top left and clock goals, you should find it there

[quaint topaz]

yes

[wide maple]

otherwise the command is mvn clean build

[quaint topaz]

can i contact you privately please i really need you

[wide maple]

my bad I have my screen flipped, top right

Sorry I don’t do that

[quaint topaz]

I have an offer for you

[dusky raven]

If it's a for hire type offer, this isn't really the kind of server for that.

There are lots of other places to hire people if you need them!

[quaint topaz]

no don't worry

[quaint topaz]

like where

[dusky raven]

HelpChat, for one. Spigot forums also have a for hire section.

[trail plume]

that's the template

do not touch the template

[quaint topaz]

ohh okay

so how do i do

[sterile stirrup]

How does rgb colors work in waterfall? For some reasons rgb colors doesn't work for me. They are just black.

[trail plume]

set the color properly...

ChatColor is not designed to be treated as a string, the client doesn't understand spigots stupid chat format and so it'll just use whatever the last hex value is as the color

(You shouldn't be putting formatting in the text itself either, use the components styling....

the spigot wiki should have an article on how to use their component system

[lean goblet]

yeah, that's not how you use components 😅

either use the builder or convert from legacy but directly setting legacy text inside component strings isn't even fully supported by the client anymore

[sterile stirrup]

Okay

doesn't work with components too.

[sterile stirrup]

what do you mean properly

[trail plume]

using the method on the Component

as said, use the builder

spigots wiki goes over how to use their component stuff

[sterile stirrup]

ok

[shut steeple]

so, incredibly dumb question

I assume the reason the travertine 1.7 patch isnt in waterfall is to keep consistency with the bungee upstream?

[trail plume]

it's a patch which is generally a PITA to maintain vs the rest of the codebase and is a "feature" which has wider implications on compat, so not suitable for waterfall

[shut steeple]

valid

[still trellis]

So, me and a friend were working to create a simple plugin, but for some reason we are getting inconsistent results when we try to run the plugin

so we start with a simple log to test if it has working and it worked

but then when we tried to create a command

it only work if the command has explicitly called "LobbyCommand" whathever other name won't work

even if we change class name

and now i just delete the command and nothing works

and it says the main class isn't called

This is the whole plugin basicly

this is the bungee.yml

[lean goblet]

I mean you don't register any command in your plugin?

(also just fyi if you ever have to hide important infromation then you should cover the whole thing including potential top and bottom of the words with something. I won't waste my time here but your way is easily reversible lol)

[still trellis]

nop

[still trellis]

i know, its not that sensitive

[lean goblet]

why hide it then?

it's not like System32 is some special phrase 👀

[still trellis]

you right

theres the version without the lines

[lean goblet]

glad I got that right, lol

as for your actual issue: please show the code with the command

[still trellis]

they don't exists

its giving error on logging on the start

for some reason

[lean goblet]

then please provide the error

[still trellis]

it dosn't give any compile error but doesn't load

and the worst part its that it worked before

[lean goblet]

well... the jar file is not a valid zip file

[still trellis]

and the we tried to add the command it failed i deleted the command and its still not working

[lean goblet]

delete it and rebuild (also make sure to clean your build space before rebuilding)

[still trellis]

thats what the build task does

it runs gradle clear rebuilds it delete the jar from waterfall and then put the new one there and run it

[lean goblet]

well check if the built jar file is actual a valid file in the gradle output

and if it is check if however you are copying it doesn't mess up the file in your plugins folder

[still trellis]

we delete the file in the plugins folder before copying the new one

and the jar seens to be right

too

[lean goblet]

so what does the content of the jar file in the plugins folder look like?=

[lean goblet]

that's in your build output

[still trellis]

could it be that intellij its running the cmd that copys the file before it finish writing it to the disk?

[lean goblet]

seeing as it's correct there my guess would be that something in the copy process corupts it

unlikely if you have the steps set to run after each other

never had issues with that when using maven and copying with IJs external tools

[still trellis]

windows copy has the problem

it has not copying it corretly

move works for some reason

It worked

[lean goblet]

odd

I have no issue with copying

[still trellis]

how do you do a utf-8 text?

[trail plume]

make sure that your compiler/file encoding is set to utf8

[still trellis]

the file it, how do i set gradle to utf8?

if its this, its already utf8, the same for the file encoding

[trail plume]

assuming the file was set that way should be fine

make sure that whatever is reading that file uses utf8

[wide maple]

When in doubt -Dfile.encoding=UTF-8

[still trellis]

this line resolved it 😄

🥝

[heavy sapphire]

Oi you stole my kiwi gag ;)

[spring oriole]

Hello, I'm developing a plugin to waterfall and I tried to setup permissions using this (on bungee.yml), but it doesn't respect (I'm using LuckPerms on server). Can anyone help me?

[trail plume]

how are you changing the perms?

[spring oriole]

In game? Using luckperms web editor

[trail plume]

Yea, that's not how that works, basically

you don't define commands in the yaml file for bungee/waterfall

[spring oriole]

Oh

[still trellis]

Interesting...

[trail plume]

You can pass the perm to the command using the super constructor

[spring oriole]

Right! Thank you

[still trellis]

@spring oriole i said it

[spring oriole]

I know

I just wanted everything organized :(

[kind hill]

In a bungee network with Bungeecord online mode on, and all other spigot servers with online mode off, will Player#getUniqueId (on spigot/paper servers) and ProxiedPlayer#getUniqueId (on bungeecord/waterfall) return different results?

[trail plume]

with ip forwarding setup, no

[simple sage]

In the server of bungeecord connected to each other,
What would be the most concise algorithm that would allow player A to move to player B on another server via the target's nickname?

I'd like to know how to do that as atomically as possible.

[trail plume]

it's done over the network and takes time, so, no idea what you mean by atomically there

[simple sage]

This means that the teleport operation proceeds through the simplest routing.

[trail plume]

basically, the server itself needs to do the final tp, so, generally you'd send some message over the network to it so that it can do the final move, and just send the player over there using

[simple sage]

thanks you

[simple sage]

I have a question.
If ConnectOther of bungee channel function
If 'Light', a user on server B, is connected,
Is it possible to run ConnectOther on server A and move it to server A by entering the nickname 'Light'?

[lean goblet]

only if you have a player online on server A

also if you are fine with using existing solutions then I have a plugin for that too 👀

[simple sage]

Assume there are enough players to send messages to both servers.

To simplify my question,
Is it possible to move the target's player to another server by entering the nickname of a user who is not connected to server A? is about.

[lean goblet]

the BungeeCord plugin message channel supports sending a player by their name to any server in the network, yes

(if that was your question)

and they don't need to be connected to the server sending the message

[simple sage]

thanks you

[lean goblet]

if you want proper teleportation I suggest using the SpawnLocationEvent and not plugin messages (as their delay might not be fast enough)

[simple sage]

What exactly is it?

[lean goblet]

what do you mean by "it"?

[simple sage]

it is SpawnLocationEvent

I don't know how to use it.

[lean goblet]

well the docs are pretty clear

(imo)

you basically specify the location the player should spawn in on join

[simple sage]

thx

[lean goblet]

instead of first loading all the chunks around the player and then teleporting them to the new chunks if teleporting on the join event

see https://github.com/Phoenix616/ConnectorPlugin/blob/master/bukkit/src/main/java/de/themoep/connectorplugin/bukkit/Bridge.java#L287-L306

[simple sage]

Thanks for your kind reply!

[lean goblet]

can you sure your reconnect handler code too?

[simple sage]

im using kfka

[vagrant prawn]

Shameless self-advert:
My AntiVPN plug-in (previously Velocity only) now supports Waterfall/Bungee, too (and is now on Velocity 3.1).
https://github.com/itsTyrion/AntiVPN/releases/latest

[lean goblet]

not too sure how I feel about blocking the event instead of using the intent system

also I would strongly recommend either running the listener at lowest priority or at least make that configurable so one can adjust it for other plugins that might also listen on those events

(e.g. if you have a heavy plugin listener on one of those events and don't want that to activate when someone with VPN tries to spam you)

also checking on ping seems a bit wastefull.

[wicked lantern]

Would be cool implement it on Wf, to avoid fast-bots.

Something like ch.close(); If it's detected invalid.

[wide maple]

That’s a very bad idea. That kind of jank leads to a lot of issues

[wicked lantern]

Well u can do it on the initialhandler too its already geting disconected if its something not good.

[lean goblet]

or, you know, use a proper firewall 👀

could easily set something up with fail2ban just reading a log file that a plugin generates when it detects odd behaviour (like vpn/too many requets etc)

[wicked lantern]

I didnt Speak about firewall

yeah low layer firewall its fine

[vagrant prawn]

?

[wicked lantern]

I saw it, 1000 requests/s it's nothing so just forget that.

ill do one with MAXMIND it's "unlimited"

[tough sierra]

ProxyDefineCommandsEvent does this include commands from backend?

[trail plume]

no

[tough sierra]

how can i control the ones from backend

[trail plume]

do it on the backend

or basically modify the packet

[tough sierra]

i do modify the packet

but protocolize is just dumb

i don't get packets sent too fast so i just got an exploit in my plugin i cant fix

it works fine on velocity

i use viaver

viaver sends the commands translatted to tab complete to 1.12- clients and when the client request too fast causing the command list to be exploited

[trail plume]

define commands is irrelevan tfor 1.12 clients

as for how that interacts with stuff like via, idk

that's outside of the scope of this channel

[tough sierra]

in packet i modify either the Suggestions or the list string depending on protocol version

am i doing something wrong

i dont think so, when the same packet is sent later i get the correct response

tbh velocity hopefully does not have this issue

atleast i get the packet on velocity

well on velocity i have Offer so

looks to happen also on velocity, ok its a protocolize problem

or tbh via problem

[tough sierra]

how can i get command owning plugin

[wide maple]

Exactly what it says; I assume you’re developing a plugin here, check the parent type

[quaint topaz]

I am editing waterfall but there is a problem

[wide maple]

Alright but that doesn’t change anything

You changed something that is required by a supertype

You have an extra @override that shouldn’t be there is what this is saying if I’m not mistaken

[wide maple]

Just as clarification; you can’t change a methods signature and keep its functionality from the supertype

[quaint topaz]

how so?

[wide maple]

Because there won’t be anything left to override or implement. The supertype defines the method signature (but not always the modifiers)
Then you’re down an implemented method but still need to replace it back
What exactly are you even trying to do here in on one of the packet handlers?

[quaint topaz]

i have a very bad problem

how to fix please help

[wide maple]

You tried to modify the handle method for the team packet in that class
And I assume you also changed something with that packet itself

We highly discourage that unless you know exactly what you’re doing

Which is also why you’ll only get very limited help with what you’re doing here

[jagged crag]

    public static void broadcastMessage(String message){
        ByteArrayDataOutput out = ByteStreams.newDataOutput();
        out.writeUTF("Message");
        out.writeUTF("ALL");
        out.writeUTF(message);
        Bukkit.getServer().sendPluginMessage(CoreBukkitPlugin.getInstance(), BUNGEECORD_CHANNEL, out.toByteArray());
    }

Hi, is it normal that the message is broadcast as many times as the number of players online?

[trail plume]

No, that thing just picks the first player and shoves a packet down their connection

[supple bane]

Is it possible with Messaging Channel to send data from the bungee plugin to a spigot plugin? Yes right?

For example if you handle commands with the bungee and create/open the inventory with the spigot plugin

[trail plume]

yes

[supple bane]

thx

[supple bane]

Is it common practice to create a new subchannel for each task? or is it better to have one subChannel and maybe send an json in which there is a specific value where i can determine what to do with the data?

[trail plume]

I just poop json around and have an "action" tag in there to say what it's tryna do

[supple bane]

thanks

[supple bane]

Any idea why the PluginMessageListener wont trigger?

[cinder pilot]

how can i stop this?

[supple bane]

Are all bungee schedueler async?

[trail plume]

Ther is no main thread

[near tinsel]

is there an easy way to make my plugin override another plugin's command?

[cinder pilot]

anyone?

[trail plume]

disable ping logs in the config?

work out what's pinging and yeet it?

[cinder pilot]

Thanks it worked! <3 Merry christmas btw

[quaint topaz]

how can i solve this problem

[bleak current]

You're assigning nothing to action

if you want the variable to stay uninitialized, remove the =

[quaint topaz]

so what should i do

[outer cosmos]

read again

[quaint topaz]

do i need to remove the code?

[bleak current]

what are you trying to do

[quaint topaz]

I want to get the jar but I can't, it gives an error

[ruby python]

I think you should learn java before attempting to code bukkit plugins

[tame vapor]

Just wondering how you guys made bungee generate spigot servers… seen many methods, which do you recommend?

[tame vapor]

You are improperly assigning the variable… do you want it to have a null value? Or do you want it be uninitialized?

Remove the ‘=‘ sign and try running it

[quaint topaz]

i can't get the jar for weeks please someone help

I really don't know what I have to do to get the jar

there is something missing i can't figure it out

[tame vapor]

Did you compile it yourself?

[quaint topaz]

yes

[tame vapor]

Using maven or gradle?

[quaint topaz]

maven

[tame vapor]

What build goal are you using?

[quaint topaz]

what?

[tame vapor]

Maven has build goals such as eg. "clean package", "clean install", etc...

[quaint topaz]

clean install

after

clean package

[tame vapor]

have you tried to run ./waterfall b from bash, get jar from Waterfall-Proxy/bootstrap/target/

[quaint topaz]

there are some errors in maven side

[quaint topaz]

it gives an error

[trail plume]

I mean, if that's the case, you broke it

as for how, idk

but, it tells you the issue in plain english

[quaint topaz]

what?

[wide maple]

From what I’m seeing looks like you broke the pom.xml somehow

Good luck fixing it, we don’t provide support for that kind of modification

[quaint topaz]

i didn't break

[trail plume]

I mean, clearly something is broke

We don't really provide support for modifications of our software, you're expected to know what you're doing

[quaint topaz]

pom.xml etc

[wide maple]

Get yourself a clean Waterfall repo clone
Better yet if you cloned it with --recursive
Run ./waterfall b to build it (you need maven in your $path and a JDK)
or ./waterfall p and change what you need to in the Waterfall-proxy folder
git add and git commit your changes, ./waterfall rb to make your changes a patch
That is the correct way to modify Waterfall, again, more extensive guide in the CONTRIBUTING.md

[kind hill]

I have a small question: why does ProxiedPlayer#chat doesn't work when using it to make the player use other commands (if the command belongs to a Bungeecord/Waterfall plugin?

And is there a way to make a player use a command from a bungeecord plugin?

[trail plume]

chat is not commands

use the dispatch command or whatever it was method

[kind hill]

thanks, I'll do that

[quaint topaz]

I compiled the original, it gives an error again why

I cloned it and got the jar directly, it still gives an error

[trail plume]

"an error"

[trail plume]

those are warnings, not errors

[trail plume]

wrong jar probs

use the shaded one

[quaint topaz]

Don't I need to use waterfall proxy jar?

[trail plume]

oh, that is the shaded one

No

you use the bootstrap jar, as you've been told multiple times

[quaint topaz]

finally worked

How can I change the cmd-alert command

I just want to change the alert command

[trail plume]

write a plugin and replace the command?

[quaint topaz]

where can i update these messages

[bleak current]

messages.properties

[quaint topaz]

thank you ❤️

[quaint topaz]

how can i remove the by message it seems very confusing

[lean goblet]

where does that even show besides the startup log?

[quaint topaz]

console

[lean goblet]

well yes, but why would that matter?

[quaint topaz]

bungeecord

I want to close the very confused in-between version

[lean goblet]

it's literally just the version of the specific cmd module

[quaint topaz]

yes ı know

but I still want to remove the version

[lean goblet]

modify how the version is included in the module I guess

[quaint topaz]

which one should i remove

[wide maple]

You can keep it and set it yourself; but also you’re in the wrong place for that, the file you’re editing is for the module downloads
Regardless, the flag -Dbuild.number=number will set that, you can just add it to the maven build command

[quaint topaz]

From which file can I edit these messages?

[warm spoke]

How do I listen to PluginMessages using waterfall?

[torpid rampart]

Use the PluginMessageEvent.
https://papermc.io/javadocs/waterfall/1.18/net/md_5/bungee/api/event/PluginMessageEvent.html

[warm spoke]

Do i need to register incoming/outgoing channels beforehand for this?

[torpid rampart]

Since it is an Event, i don't think so.

[warm spoke]

Im trying to send a PluginMessage by doing

            event.getPlayer().sendPluginMessage(DraelCraftHub.getInstance(),"dch:joins",
                event.getPlayer().getUniqueId().toString().getBytes(StandardCharsets.UTF_8));

and

    getServer().getMessenger().registerOutgoingPluginChannel(this, "dch:joins");

it doesn't show up on the proxy, i.e. it doesn't go through (i suppose)

[warm spoke]

it doesn't show up on the proxy

public class HubJoinEvent implements Listener {

    @EventHandler
    public void onHubJoin(PluginMessageEvent event) {
        System.out.println(new String(event.getData()));
        System.out.println("tag"+event.getTag());
    }
}

I get a lot of random messages from other plugins but not from mine

[warm spoke]

or if someone here did this stuff successfully could they share how they registered stuff?

[trail plume]

the sender registers stuff

i.e. if the proxy wants to send stuff to the server, it needs to register it

[kind hill]

Every time I start my waterfall plugin, these messages are printed in red because I think Waterfall/Bungeecord doesn't like having other loggers being used

[19:17:09 ERROR]: [main] INFO com.github.secretx33.dependencies.friends.hikari.HikariDataSource - HikariPool-1 - Starting...
[19:17:09 ERROR]: [main] INFO com.github.secretx33.dependencies.friends.hikari.HikariDataSource - HikariPool-1 - Start completed.```
Logger used
```kt
runtimeOnly("org.slf4j:slf4j-simple:1.7.32")```
But I just put it there because otherwise Hikari prints a huge complain about operating in "no-op" mode or whatever. Is there a way to make Hikari (and others `sl4j` consumers alike) use Waterfall default logger, and if so, how can I do that?

[warm spoke]

I want to do the opposite

My specific use case is i want my spigot plugin to message my proxy telling it a player has successfully joined the server, to which the proxy will respond by telling the spigot plugin with which subdomain it connected with, i.e. survival1.example.com/survival2.example.com, so that the player can be joined to a queue appropriately

[wide maple]

But that data is forwarded already to the server when you have forwarding enabled?

[warm spoke]

?

[wide maple]

Regardless; you need to register an outgoing and an incoming namespaced:key formatted channel for either

[warm spoke]

If you mean in the spigot plugin, I did.

[wide maple]

The server should have the hostname the client joined from if you have forwarding enabled. Getting it should be the same as getting it on a server without bungee

[warm spoke]

Do you mean ip forward?

[warm spoke]

And how would I do that?

[wide maple]

player.getAddress().getHostName()
If that doesn’t work and forwarding is enabled then let me know

[trail plume]

you'd need a plugin for that, but, yea, it's doable

[simple imp]

is it usefull to ask for upstream? my console is screaming a lot 😉 https://ci.md-5.net/job/BungeeCord/1627/

[trail plume]

screaming?

oh

I already did an upstream locally but didn't push

That's like, 20ms though?

if you've got shit blocking for THAT long, you've got issues...

[simple imp]

[18:56:12 WARN]: Plugin listener com.loohp.interactivechat.proxy.bungee.InteractiveChatBungee took

i may have issues yes still struggling with tab and interactivechat using pluginmessaging a lot

if you have advices on how to optimize thoses delays (cpu is ok, ram is ok) i get thoses messages when more than 60 players in my bungee network

[trail plume]

That's the network pipeline.

Like

you've literally got plugins blocking the network pipeline

[simple imp]

it's on the same machine communicating within pterodactyl dockers

[trail plume]

literally irrelevant

[violet saffron]

The problem is the data being sent / how it's sent. It would be more in the place of the plugin developers to optimize.

[simple imp]

sorry my knowledge on networks is limited to outside connexions i have trouble when it's internal

[trail plume]

You have plugins doing things which are stupidly expensive

[simple imp]

yeah always the same issues: user experience VS plugin performance/code quality

[trail plume]

That means that when interactive chat runs, your player is gonna be a full tick behind where of packets

and that can impact other players

[simple imp]

only for the chat, gameplay do not seems to be affected

[trail plume]

No

each player has a pipeline

[violet saffron]

The underlying code being ran here is part of the problem https://github.com/NEZNAMY/TAB/blob/884b5755ece5ca7ed16aa9dbdaa38bc7e1c16c38/bungeecord/src/main/java/me/neznamy/tab/platforms/bungeecord/BungeeEventListener.java#L34

[trail plume]

bungee pretty much always fires events in the pipeline

[bleak current]

[23:03:47 WARN]: [/127.0.0.1:57327] <-> InitialHandler - overflow in packet detected! A string had more data than allowed. For more information, launch Waterfall with -Dwaterfall.packet-decode-logging=true
Anyone know how to fix this?

[torpid rampart]

Does that happen regularly or just once

[bleak current]

Every join

I think it was a fallback server error

I changed the address to my hub IP and now i get this error in the picture attached

  lobby:
    address: 127.0.0.1:25570
    motd: '&1Welcome to Safehouse!'
    restricted: false```

[torpid rampart]

is the port right?

[bleak current]

The port needs to be the same as the hub servers right?

[torpid rampart]

as the hub server

you can't have multiple servers on the same port

[bleak current]

Is there a step by step guide on waterfall?

[torpid rampart]

Maybe you can use the installation instructions for Bungeecord: https://www.spigotmc.org/wiki/bungeecord-installation/
https://www.spigotmc.org/wiki/bungeecord-configuration-guide/

Waterfall is a fork of Bungeecord, so taht should work.

[high pier]

Can anyone tell me how to make this happen on bungee?

[bleak current]

Hey!
Is there a way to allow players with a modpack instance to login to a spongeforge server? They'll need to join the hub (has 0 mods installed), in order to pass through and get to their modpacks servers.

[trail plume]

you can't, basically; Not if the thing requires mod packs

1.12 and before where somewhat more accepting but modern forge just doesn't work

[bleak current]

Isn't there some sort of bypass? Or a mod/plugin that can be coded to help bypass this check?

[trail plume]

Don't mention.

It's not down to there being a check

You need data to line up, you do that by making sure that the expected crap is there, i.e. the mods

for modern forge support, if you see the issue tracker, there is an issue tracking this, and in there there is a waterfall fork and a mod which apparently works but looked kinda dead so 🤷‍♂️

[bleak current]

So it is possible to create something which'll fix this issue?

[wide maple]

Without modifying the client? Possible; kinda, but limits the player to either forge only or vanilla only

[bleak current]

Well the player would be joining the spongeforge server (or whatever works) with a modpack instance and then going from there to their relevant server...
Would this be something you have the skillset to code?

If so i'd love to commission you maybe?

[wide maple]

Even if I did that it would barely be usable, mods freeze at random, client glitches out, inventories desync and so on. No, this isnt a workable solution

[bleak current]

What kind of solution would be workable then?

[wide maple]

A mod for client and server, or some sort of unified client reset protocol (which both dont really exist yet)

[simple imp]

for your information, my issues with interactivechat and tab were almost instant solved by the devs that gave me an updated better version of their plugins

[pastel hill]

[spring oriole]

Is it possible to detect when the end command is executed and delay the proxy closing to, for example, warn users that the proxy will close in X seconds?

[trail plume]

make your own end command and replace the proxies, basically

[spring oriole]

ok, thanks

It's possible to play a sound to all players from proxy?

[north pelican]

when I try to connect bungee to bungee
I get this error that i send too many packets
1222 bytes (max is like 1k)
can i set the max or smthn?

[21:31:13 WARN]: [/172.18.0.1:50790] <-> InitialHandler - overflow in packet detected! Cannot receive string longer than 1020 (got 1222 bytes)

woops

wrong channel

[grave fulcrum]

is config stuff safe to do async

also how do async tasks work

                if (minsSinceLastPaid >= countTime) {
                    main.getProxy().getScheduler().runAsync(main, () -> {
                        final int existingPoints = main.getMySQL().getPoints(player.getUniqueId());
                        main.getMySQL().setPoints(player.getUniqueId(), player.getName(), existingPoints + countReward);

                        player.sendMessage(Main.replaceAmpersand(config.getString("CreditsReceived")));

                        main.getLastPaidMillis().put(player.getUniqueId(), System.currentTimeMillis());
                    });
                }```
i have this but it doesnt work

LastPaidMillis is a map with UUIDs and longs

[vocal phoenix]

is this wrong or why doesnt it get called

[outer cosmos]

PlayerJoinEvent seems to be a bukkit event.

[vocal phoenix]

it is

is that wrong?

[outer cosmos]

Bukkit events are not triggered by a proxy.

[vocal phoenix]

so how do i fix that?

[lean goblet]

you use the proxy event

[outer cosmos]

By either running that plugin on a Paper server or switching to the proxy event.

[vocal phoenix]

its on a paper server

[lean goblet]

then it should work if you registered it

[outer cosmos]

Then you're in the wrong channel.

[vocal phoenix]

its in the main class

[vocal phoenix]

oh sry

[bleak niche]

hi

im currently trying to send a player to another server

is there documentation on the channel sysem for plugin messages

[bleak niche]

I looked at that page already, their examples there dont even work due to them changing how the channels work

[trail plume]

changing how the channels work?

use bungeecord:main i think it was if not on some spigot fork

think it was called that

[bleak niche]

from what ive seen yes

ah im using bungeecord:legacy

ill give that a try, thanks

[bleak niche]

there were definitely changes, they use BungeeCord as the example channel though that will not work as they require it to be all lowercase now, in my testing using bungeecord as the channel doesn't work either

[trail plume]

I mean, vanilla changed the format

spigot just did some stupid hacks instead

wooo

[bleak niche]

I wouldn't mind it if I could find updated information about those changes :(

[trail plume]

legacy uses BungeeCord

[bleak niche]

spigot update notes haven't mentioned it from what ive seen

[trail plume]

can't send BungeeCord over the pipeline anymore

and, so, spigot basically made some logic which transforms BungeeCord to bungeecord:main and then back on the other side

[bleak niche]

ahh

[bleak niche]

Hey so im still trying to send players to another server on spigot```java
//registering, this is in the onEnable
getServer().getMessenger().registerOutgoingPluginChannel(this, "bungeecord:main");

// sending the user later via a function
ByteArrayDataOutput out = ByteStreams.newDataOutput();
out.writeUTF("Connect");
out.writeUTF(server);
player.sendPluginMessage(Main.getInstance(),"bungeecord:main", out.toByteArray());```

Im running latest Waterfall

[trail plume]

use BungeeCord

(as the channel)

the entire thing is basically janky due to upstreams workarounds for that

it can act... odd..

[bleak niche]

alright

I think I got an error when I tried using uppercase chars

ill send the errror if I get that lol

[trail plume]

explictly BungeeCord

the translation logic there is stupid

[bleak niche]

im using BungeeCord exactly

[trail plume]

using bungeecord:main will try to convert it to BungeeCord when it tries to send

[bleak niche]

[20:51:45 ERROR]: Error occurred while enabling GridBedwars v1.0-SNAPSHOT (Is it up to date?)

[trail plume]

remove :main

[bleak niche]

That worked , thank you

[gritty thicket]

hey

[sonic glen]

Hello,

I wanted to ask a quick question:
How can I manually update the commands available to tab complete for a player.

Currently the player receives only commands he has access to, which is done with the event "ProxyDefineCommandsEvent". Now I coded my own Permissionsystem and I want to update the commands manually, when a permission is added or removed.

[trail plume]

You can't

You'd need the entire command structure to resend, which, unless you save a copy when the server sends it, you don't have, and, is a nice chunk of memory if you did

[balmy perch]

how can i get all proxyservers and judge if each of them is connected to bc?

[lean goblet]

ProxyServer#getServers then check if they have players or ping them

[balmy perch]

Oh thanks, i will try 👆

💕

Aww, how can i ping a server?

[verbal turret]

is there a helper method/library for translating a string username into a uuid (or returning does not exist) for xbox players? particularly useful if it can be called independent of a waterfall-enabled server (standalone java app tied to a webpage for whitelisting)

[trail plume]

waterfall has nothing to do with xbox players

[verbal turret]

wait am i getting it mixed up with soemthing else? i thought it was the one for bedrock support on bungee

[trail plume]

no

that's geyser

[verbal turret]

then yes i am mixing myself up XD

sorry bout that

[wide maple]

When you use geyser and floodgate it will generate a usable UUID for the player based on the XUID of the account logged in. There is a way to get the XUID back from the UUID but I’m not sure why you wanted to do that

[verbal turret]

i just wanted to be able to whitelist somebody who was not currently on the server

ideally from an app that was not itself required to be installed on the geyser server directly

xuid, uuid, idrc so long as i can reliably whitelist. haven't done much digging yet but it's on my list of things to do in the next month or so

[bleak current]

Hey I need help proxy can someone help me my plan is to create 2 waterfall network 1 is cracked and 1 is premium and make a 3rd waterfall to collect those 2

[wide maple]

Piracy isn’t supported and stacking proxies isn’t possible with waterfall/bungeecord without modifications to the proxy directly.

[cobalt otter]

Ok but plugins

Maybe do that

Like plugins on paper server

[cobalt otter]

Will not let the crack players enter the server can that possible

[bleak current]

online-mode: true?

[cobalt otter]

Well idk if you know bungee don't work when server is in online mod

[bleak current]

You set your backend servers to offline mode, not the proxy

[cobalt otter]

point is i am saying creating proxy in ofline mod

but it should work in a way some gamemodes only premium players can acces

[cobalt otter]

anyone can hellp?

[lean goblet]

with what?

[bleak current]

lmao

[bleak current]

ServerInfo addServer​(ServerInfo server) is deprecated. How should I interpret that, that it's soon is removed completely or is there an alternative function I can use?

[trail plume]

the entire config class is deprecated

[bleak current]

Alright, if I want to dynamically allocate a server to my proxy, do you know a reasonable way to do that? The idea is if a server is offline on connecting to the proxy, it will provision a new server instance at arbitrary cloud platform and link it to the proxy.

[trail plume]

using that method you highlighted

the class is deprecated because it can change often

[bleak current]

Okey I see, thanks. Is Waterfall the approach to go, as I'm creating a new thing should I transition to Velocity instead?

[trail plume]

waterfall in general is deprecated and velocity is much more shiny and robust

[bleak current]

Oo shiny, I do like that. I'll have a look at it, thanks.

[graceful kestrel]

I really want to know how to setup multi bungee someone pls hlp

[trail plume]

depends exactly on what you even mean by that

proxy in proxy is not supported

running multiple proxies side by side is, and, like, you just do that

[edgy hedge]

connect​(ServerInfo target, Callback<Boolean> callback, boolean retry) how does retry logic work? does it retry only once or does it retry X times? Is the callback executed on each failure/success or is it executed only once at the end?

[trail plume]

er

off recollection, that's called for when the proxy itself is retrying

or is a signal to use the priorities list for fallback or something

oh, no, that's api one, er

no idea, you'd need to look at the impl

I mean, it says it retries the connection, as for how many times it retries, I think it was only once but, ^

[edgy hedge]

ok, I will see, it was unclear to me because javadocs have description copied from the other methods without any new info regarding reconnection part

for some reason sometimes I cannot connect players to the target server that is 100% healthy and the error in the callback is null O_o

So I now think about implementing some retry logic, probably my own

[lean goblet]

never had that happen tbh, how are your servers connected?

[edgy hedge]

all are on the same machine connected through the waterfall

[lean goblet]

and they are definitly connecting through localhost connections?

[edgy hedge]

in all server properties I have 127.0.0.1

so only local connection is possible

[lean goblet]

odd

[edgy hedge]

like 3 in 100 connections are failed cuz of null error
