[burnt dragon]

although, i don't think velocity supports sending even named sounds tbh

[dreamy kite]

where i can modify the velocity language message?

[bold wharf]

at this moment, modifying the jar is the only supported way

can extract the locale file and place it back in

[dreamy kite]

the file location?

[bold wharf]

don't remember, see the search 🤷‍♂️

[dreamy kite]

[inner skiff]

i'm having a kinda of an weird issue where the first item of the message is not colored

all the rest of the message is normal

except for this first [

and it makes no sense for my why

[burnt dragon]

.style sets the entire style of the component

as you've created a style that just contains bold text, the colour will not exist in that style

[inner skiff]

so i should put a .color after?

the .style?

[burnt dragon]

just do Component.text("hi", NamedTextColor.RED, TextDecoration.BOLD)

[vestal prawn]

is there a documentation on how to use Configurate ?

https://docs.spongepowered.org/stable/fr/plugin/configuration/index.html

found, i let it here for those who wonders

i'm getting this weird error when trying to run my plugin, and it only seems to happen if i have a ProxyInitializeEvent listener registered

[ashen fiber]

Can I see your event code?

[patent portal]

https://paste.gg/p/anonymous/623a83ad0a924f38b557ea09294cae03

[ashen fiber]

¯_(ツ)_/¯

I have no idea.

I have ran into this before with a different event.

I never found a solution.

[patent portal]

[fossil sundial]

That’s the wrong logger
Inject the Log4j logger

[patent portal]

is this not the log4j one?

[ashen fiber]

Are you sure about that? Same logger I use.

org.slf4j.Logger is definitely the one you are meant to use.

[fossil sundial]

Alright my bad

But I’m surprised nonetheless

[patent portal]

i'm just confused lol

[ashen fiber]

@patent portal I suspect something wen't wrong when building your plugin, have you tried a clean build?

[patent portal]

if what you're referring to is ./gradlew clean build, then it still yeilds the same results

[ashen fiber]

Hmmm

Ya then I have no idea.

¯_(ツ)_/¯

[patent portal]

ok i fixed it

i'd forgotten to add that org.xyz.something folder structure to my src, and thus the files were at the root of the jar
i'm no java wizard but for some reason that fixed it

[twilit timber]

off-topic, but which font is this?

Heya
Interesting query for anyone familiar with Velocity internals

A little while ago I ported the FakeProtocol plugin to Velocity so I could do a network migration from bungee to velocity because... well velocity 🙂

Everything in principle operates fine. I can define my list of allowed protocols. If the client is unsupported, I can display my custom message showing what versions our network supports. Happy days.

However. If the client is using an allowed version. They can connect OK. And they see the player count format expected and stuff. But the ping status shows incompatible version (as per the attached screenshot). Has anyone got any thoughts on this? I can't make sense of it for the life of me!

Actually
Ignore this completely!
As soon as I posted this I had another thought of where the issue lies and it turns out the bug is with ServerListPlus - not my port of FakeProtocol. I'll direct the query their way.

[hollow merlin]

Is there any possibility to fork Velocity like one can fork paper or waterfall?

[proper steeple]

Yes

[hollow merlin]

Is there any documentation on this topic or maybe even an example?

[agile ore]

hi it tells me this velocity error when i run a command how can i fix it?

[proper steeple]

No need to cross post

[agile ore]

ah ok

[agile ore]

how can i fix that error?

[proper steeple]

By not crossposting and patiently waiting for a reply, by providing the most information possible.

[agile ore]

ok sorry i tagged you but it's an urgent problem

[proper steeple]

That doesn't change anything

[agile ore]

ok

[hollow merlin]

Or Is there even an tool for this like the userdev plugin? Or can I use the Userdev plugin for this in any way?

[fossil sundial]

Work on it like you’d work on any other open-source java project that uses gradle. Velocity isn’t a fork and doesn’t use any kind of patching system; its just a normal project. You dont need any special plugins in your JRE other than the ones automatically provided by gradle.

[light tendon]

I want to send a player message containing a link, but it doesn't seem to be clickable

anyone can help me?

[fossil sundial]

just add a .clickEvent(ClickEvent.openUrl(String/URL)) to your component

[light tendon]

thanks

[real kelp]

right now i have a network library that hooks into paper plugins on my subservers and automatically loads and saves data from MongoDB. the issue i am currently having is figuring out how to update this data when someone does /link (from a velocity plugin). would redis be the best way to do this?

Also, would it be better to just cache playerdata on the velocity plugin and put it in the redis database, so that when a player joins a subserver i dont have to query mongodb but rather redis? not sure what is best for data synchronization

[worldly torrent]

Absolutely yes you want to be querying redis for sync data
it's what I do and its fkn quick. If I made a DB query of any kind I'd be introducing a lot of overheads.

[valid bone]

How would I go about getting the ip address the player is using, when connecting to the proxy server? I know I need to listen on the server ping event, and I believe I need to use the getConnection method on the event. But I'm unsure how Velocity passes the IP from there.

[ashen fiber]

InboundConnection.getRemoteAddress()

Please check the javadocs in future.

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/InboundConnection.html

@valid bone

[warm gulch]

maybe they want getVirtualHost, unclear wording

[ashen fiber]

maybe?

[valid bone]

I want the forced hosted ip

[ashen fiber]

What do you mean by that?

[valid bone]

IP being domain.com, then getting subdomain.domain.com

I would say it's the getVirtualHost method, but the InetSocketAddress class link returns a 404.

[valid bone]

Also, I did check the javadoc. But thanks.

[ashen fiber]

This is probably what you want
https://docs.oracle.com/javase/8/docs/api/java/net/InetSocketAddress.html

[valid bone]

I'll check it out. Thank you.

[neon shuttle]

the getVirtualHost return the hostname the player used to connect to the server with. For e.g if the player connect with "play.google.com", the virtualHost will be "play.google.com"

[valid bone]

Alright. Thank you.

[neon shuttle]

it can be null, but I don't under which circumstances it could be

[valid bone]

I'll keep an eye out for that. Thank you for the heads up.

[real kelp]

so I should load mongo on the proxy, and cache it in redis, and then when a player joins a subserver take the information from redis instead of directly mongodb? also is pub sub the best thing to use for this? i have all of the sub servers subscribed to the proxy and the proxy pushes updates to the other servers?

[ashen fiber]

If both the proxy and the server need to get information from MongoDB, just get it.

[real kelp]

k, and ill just use redis to push msgs

[ashen fiber]

Use Plugin Messaging Channels

[ashen pawn]

yes, all commands are executed asynchronously

[latent coyote]

Is the velocity still updating ? Because I didn't see any new commit since a long time

[coarse topaz]

Yes it is

[latent coyote]

Ok, and is there a branch of somethings else to know the development status ?

[coarse topaz]

There are a few PR's open that will likely be merged in the future. Tux, the primary author of Velocity has a full-time job, and is very limited on how much he can contribute

[latent coyote]

ok thanks 🙂

[latent coyote]

is there a way to disable velocity tablist overriding ? I'm trying to send tab from server, but doesn't work on velocity

[coarse topaz]

I know this was brought up before, but I would like to get some opinions on adding a trailing comma to the versions in ProtocolVersion, the only benefit of this is to not override git commit history

[valid gazelle]

i always use trailinmg commas in programming because of that

[oblique haven]

How/why would it affect git commit history? I don’t think I’m fully understanding

[coarse topaz]

With how it is currently setup, the last version enum has a ";". With that, every time a new version is added the version before it has a new commit message

for example, this is the current way we do it:

Do note, my commit message has changed the message for MINECRAFT_1_18

this is what I am proposing

[valid gazelle]

yeah

[maiden hawk]

So, I cloned Velocity and needed to edit log4j2.xml, however now Gradle refuses to build. Is configuration editing forbidden?

[thick bramble]

no, but you don't need to edit velocity directly to do that. you can specify a custom log4j config file by starting velocity with -Dlog4j2.configurationFile=file.xml before -jar.

[maiden hawk]

I actually do that to fix a bug that occurs in Velocity.

So this is intentional.

[bronze yoke]

why not contribute

[maiden hawk]

That is indeed what I am attempting

[bronze yoke]

ah alright

[maiden hawk]

However I want it to build first before contributing

(Which kinda makes sense)

[thick bramble]

yeah of course, I am not familiar with velocity, but my guess on your issue is that you accidentally edited the license header at the top of the file which it checks on build

[maiden hawk]

Oh lol, I did not, but I added a comment which didn't have space after the license declaration, it works now, thanks :D

[glacial kraken]

Bungee plugin messages (especially the one to move player to another server) work on velocity too? Or there are changes

[rich hawk]

They work

[maiden hawk]

They work by default, however, it can be disabled in Velocity config

[brisk mortar]

Can I open a Inventory through velocity

[ashen fiber]

Velocity can not access information about the servers state*

[brisk mortar]

That means i can not?

[glacial kraken]

Exactly

You cant

But depends on what you want

You can manage to open inventory gui

[brisk mortar]

But not listen to a click? Or what you mean

[maiden hawk]

In theory yes, but in practice not really and Velocity doesn't offer any API for it afaik

[round quiver]

Hey, a quick question, does Velocity have a broadcast method? (I can't find one)

[burnt dragon]

Anything that is an Audience has sendMessage methods - this includes ProxyServer and RegisteredServer, etc

[round quiver]

So f.e. ProxServer#sendMessage sends to all connected players, and RegisteredServer#sendMessage to all players on that server?

[burnt dragon]

yes

[round quiver]

thx

[obtuse locust]

what event is handled when spigot server shuts down and kicks players? And can I move players to another spigot server?

[burnt dragon]

the disconnect event is fired

er, or is it the kick event

[maiden hawk]

Actually this is kinda odd, I've found out that Purpur does indeed kick the players, however paper and it's "predecessors" seem to just disconnect the player

Tho it would need some more testing to prove.

[burnt dragon]

is this a #paper-dev question?

[maiden hawk]

No I guess.

Just saying, that whether disconnect or kick event will fire may vary on the server you are using.

[reef jacinth]

That wasn't meant for you, the question that was responded to was deleted.

[maiden hawk]

Oh lol, thanks, it seemed kinda odd.

[bold wharf]

paper kicks players too

all of them do, it's literally a vanilla thing

big thing is gonna be the order of which stuff occurs

I have a feeling that purpur fucked with that one

[maiden hawk]

Idk, it is possible. I am just saying what I've observed

On all server's except Purpur I just received a general disconnect.

[bold wharf]

don't mention

[maiden hawk]

oh ok

[bold wharf]

player are kicked late in the process

so, you're not gonna even get an event fired because your plugin is disabled before then

iirc, purpur messed with the order so that the events are fired or something

but, I don't really care to track what they do, I just remember there being some complaints around that

[maiden hawk]

I think that the question was about which event will fire for the players on the proxy, when the server they are connected to will close.

So if you have a velocity plugin, it is still going to be enabled when players get kicked from those servers

[amber ridge]

Hi, where do i find list of all events and description of it?

[rich hawk]

channel topic

[amber ridge]

Um, okay but i need help which event is called when player just disconnect from proxy, not get kicked

[bold wharf]

the connection closing is the connection closing

[burnt dragon]

that's the cleverly and aptly named "disconnect event"

Where in velocity's code are the log files?

need to make some edits to how velocity logs things for my server but can't find it

I need to remove the player IP from logs

[tawdry sky]

https://tenor.com/view/gameboyluke-please-help-me-reaching-out-gif-23555158

[oblique haven]

https://logging.apache.org/log4j/2.x/manual/filters.html

here ya go

👍

[tawdry sky]

ty

[oblique haven]

https://logging.apache.org/log4j/2.x/manual/layouts.html

or this

[tawdry sky]

this should hopefully work

[oblique haven]

that has no context so

maybe, maybe not

[tawdry sky]

https://github.com/PaperMC/Velocity/blob/dev/3.0.0/proxy/src/main/java/com/velocitypowered/proxy/connection/client/LoginSessionHandler.java

playerIp string

[oblique haven]

0,0 oh

okay

that's definitely the wrong way to go about things, but... okei

[tawdry sky]

would it break something else

?

[oblique haven]

I mean, it's just a very bad way to solve the issue, you can just replace IPs in the filter

[tawdry sky]

and how exactly would I do that? I don't know this log4j stuff

[oblique haven]

https://logging.apache.org/log4j/2.x/manual/layouts.html
Pattern layout - %replace method, match on IP regex

or match whatever thing you want

[tawdry sky]

Cool but where do I put that

[oblique haven]

in the log4j configuration file, one is already provided by velocity, and since you have the source open it's in one of the resources folders, you just have to look for it

[tawdry sky]

ty

this?

[oblique haven]

yep

https://stackoverflow.com/questions/12579468/how-to-set-log4j-property-file then this kind of explains how to use a different file than the default provided

can also use -Dlog4j2.configurationFile=file://file/path/log4j2.xml sys property

[tawdry sky]

mind giving me a code example?

tried it to no success

[oblique haven]

what did you try?

[oblique haven]

of setting the config file?

just use the sys property

java -Dlog4j2.configurationFile=/home/fixed/server/log4j2.xml -jar server.jar

there's some example usage

[tawdry sky]

That wouldn't work as we run multiple proxies that often get changed over multiple networks

only takes one person to fuck up

GDPR is not a fun thing

[oblique haven]

You don’t have control over your command line flags?

[tawdry sky]

I do, of course, but I just don't find having something this important in a startup command very appealing

[oblique haven]

Don’t modify the source of the proxy, that’s such a bad idea

[tawdry sky]

why?

[oblique haven]

It forces you to constantly maintain the fork rather than taking a non intrusive approach

[oblique haven]

I mean, you can make a java agent

And pre main set the sys property

[oblique haven]

This contains code examples of setting system properties, I’m not gonna teach you how to make a java agent tho

[tawdry sky]

I don't think hitting "fetch upstream" and rebuilding is that hard lol

[oblique haven]

Then feel free to just modify the log4j config file built into velocity

[tawdry sky]

well that's the problem
in the year that I'm working with java I never did anything with that

[oblique haven]

Just modify this

[tawdry sky]

but what do I modify inside it

[oblique haven]

Read the documentation for log4j

I’m not gonna write your config for you

Use the PatternLayout and use %replace to match IPs, I gave you a resource for regex matching IPs earlier

[oblique haven]

This essentially

[hidden breach]

How can I get the plugin config in Velocity from a plugin?

[worn pond]

Hey, I have a small issue with Velocity.
How can I redirect a player when a server went down ? According to velocity's java doc, It should be done when the KickedFromServerEvent is fired and then I should use KickedFromServerEvent.RedirectPlayer to redirect player to another server but it doesn't works for me. Player is kicked from the proxy with "Disconnected" message.
Here is what I use to do that :

KickedFromServerEvent.RedirectPlayer.create(foundServer());

foundServer() is a private method aims to found a available server, it's return a RegisteredServer object
I've also tried to done that redirection with the following code :

player.createConnectionRequest(foundServer()).fireAndForget();

Thanks for your help.

[burnt dragon]

redirect player is definitely the correct thing to use

are you sure you're setting it correctly?

[worn pond]

I found my mistake : I did not use the event.setResult(), I thought that what I wrote above was correct but not.
The correct way to do that is :

event.setResult(KickedFromServerEvent.RedirectPlayer.create(registeredServer));

[craggy pecan]

There's no predefined config file, although you can use Configurate to load and save config files. You can inject the plugin's data directory with the @DataDirectory annotation

[amber ridge]

How do i send player to server X in paper plugin?

[bold wharf]

use the bungee messaging channel

see the spigot wiki

[amber ridge]

Okay, thanks

I found this
server.getMessenger().registerOutgoingPluginChannel(this, "BungeeCord"); but i didnt know if i have to change Bungee to Velo

[bold wharf]

No need to change anything, it works the exact same, otherwise having it built into velocity would be somewhat pointless

[amber ridge]

Hm i got a little problem, i have

Player player = playerAll.get(0);
player.sendPluginMessage((Plugin) this, "BungeeCord", out.toByteArray());```, intellij marks me `(Plugin) this` but i dont know how to fix it, my error
```java.lang.ClassCastException: class pl.siecmc.siecmcqueue.SiecMCQueue$1 cannot be cast to class org.bukkit.plugin.Plugin (pl.siecmc.siecmcqueue.SiecMCQueue$1 is in unnamed module of loader org.bukkit.plugin.java.PluginClassLoader @28#0703af815b; org.bukkit.plugin.Plugin is in unnamed module of loader 'app')```

[bold wharf]

wrong channel

it wants the Plugin instance, you can't cast random things to random things and expect it to work

[dusty mesa]

Is there an easy way to create a new @Inject instance?

Or I would have to use the guava injection stuff?

[vapid prawn]

Hi how can I get the absolute path of the plugins folder?

[gritty valve]

@DataDirectory Path path

Hey guys, how can I kick by ip in the event.connection.ConnectionHandshakeEvent?
The player object has not been created yet

[bold wharf]

See the javadocs...

if you look at that event class on the JDs it'll basically spell it out

[agile ore]

hello do you know how to solve this error when i try to connect tell me this how i can solve i await answer thanks: 0

[bronze yoke]

it basically tells you what's wrong

[gray hedge]

How do I load a plugin runtime?

[coarse topaz]

You don't load a plugin after Velocity is already running

The plugin should be loaded during startup

[gray hedge]

Yea well what I have is a jar loader which downloads the jar at runtime and loads

And one solution would be to just include in the class path and load it, but that is not an option since that would have breaking changes

I guess I'd have to use some reflection magic

[warm thistle]

hi

how can i port https://github.com/TeamKun/ServerTeleport/tree/v1.0 to the latest Velocity?

[bold wharf]

the docs site includes information on porting

[warm thistle]

I just don't get it

[bold wharf]

don't mention

are you a dev?

[warm thistle]

I know basic command and I learn new commands

[warm thistle]

You can help me or you can port this version

[bold wharf]

no

[warm thistle]

do you know someone who will help me?

[bold wharf]

Stop mentioning me

This isn't the place for solicitation

[warm thistle]

sorry

[bold wharf]

seriously.

[warm thistle]

it is out of habit

[outer flower]

So I've got a ticket management plugin that I'm looking to make work with Velocity. Would it be better to make a Velocity-specific plugin that gets placed only on the Velocity server, or should I make the individual Paper plugins communicate with each other? Not sure how it all works and what is/isn't possible

[bold wharf]

depends on needs

if it's just using commands/chat, etc, no reason it has to be on the server

[outer flower]

Yeah, it's purely through commands and chat

Awesome, thank you!

[oblique haven]

except for the idea of having dumb proxies

[bold wharf]

something like that would be trivial to abstract out into being able to run it in multiple environments

[outer flower]

Weird question, but is there a way to asynchronously send out a channel message and wait for a response inside the same function? Trying to grab permission groups for particular users, and I was going to delegate that to some plugin on the individual server

[half locust]

Luckperms-velocity + LP api

[outer flower]

Yeahhh, that's the first thing that came to mind. I was just trying to not rely on a particular permission system

Sounds like the only practical route though

[bold wharf]

I mean, it pretty much is outside of sync calls off main and praying that the perm plugin deals with that properly (and, many just don't)

theres no built-in way to wait for a response to a plugin message, you'd basically need to do that yourself and implement the entire layer yourself

[opaque escarp]

I just updated it, if you want you can try it https://github.com/4drian3d/ServerTeleport/releases/tag/1.1

[craggy pecan]

Tip: instead of collecting multiple streams to lists in https://github.com/4drian3d/ServerTeleport/commit/f10bb76ccb39aac7532b172dba92c0cbbb96caa4#diff-1e89f04b31b77ba6eaf7031357d96a5af632b2df4394892397c3a52911de15d1R77, concatenate the streams (see Stream.concat, https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/util/stream/Stream.html#concat(java.util.stream.Stream,java.util.stream.Stream)) and then collect (that way you avoid unnecessary allocations)

[gray hedge]

Can anyone explain this?

Found the issue

[royal pulsar]

There's no way to mess with arbitrary packets being sent, right?

Only chat and plugin messages?

[oblique haven]

What do you mean by arbitrary packets

Also C2S or S2C, they both have different specs for what’s even decoded

[royal pulsar]

S2C, trying to replace colors in chat, books, signs (obviously all three of those work differently and I'm aware of that, I've just never used Velocity before)

Honestly, what I'm doing might be out of scope for Velocity now that I look at it more

All I want to do is intercept chat messages, items being put in slots (so I can intercept book text), and block entity data being sent

Protocolize might be able to pull it off, actually

[oblique haven]

maybe, it's going to put A LOT of strain on your proxy

is there any reason you're not doing this on the server?

like is there a specific reason for it to be going on the proxy? The server can handle it in a much better way

[royal pulsar]

Sponge doesn't really make it easy to do this either, honestly, just because of how its API is

[oblique haven]

I mean sure, doesn't put less strain on the proxy though

[royal pulsar]

Ideally this would just be a client mod, honestly

[oblique haven]

the issue is the proxy needs to take care of 1.7~1.18.1, that's quite a lot of versions - the less packets it has to take care of the better

and that's true for any proxy

[royal pulsar]

That's fair

[oblique haven]

the server has to take care of all of em

so they're already in their raw form when you need to intervene

intervening before they get dumped into bytes and sent into those channels is probably the best way to go about it

creates the least amount of strain on the system since you're not doing a bunch of translations to get there

or put it on the client - that's always a good way to go

[royal pulsar]

Yeah, that'd be ideal, I was just trying to avoid Mixin hell, but if it's not gonna work well on the proxy, I'll go back to trying to do it on the server. Thanks for the advice on that!

[outer flower]

Anyone familiar with using Luckperms with Velocity?

[valid gazelle]

yes

[outer flower]

Is there a way to (a) get the roles on a particular server, and (b) check a user's permission for a particular server? The server in question is the server the player is actively on

Not sure if when you check a player's permissions it checks for the server they're actively on or not. The lp documentation seems to be written mostly under the impression that it's operating on a single server

That and I'm also rather unfamiliar with the LP api. Read the documentation, but it feels more oriented towards single-server stuff

[last cliff]

configure luckperms to sync its data
https://luckperms.net/wiki/Syncing-data-between-servers

then use context

[warm thistle]

thanks

[obtuse lintel]

I don't suppose there's any documentation relating to manipulating the tab list with Velocity?

[bold wharf]

given that theres no scoreboard API, yet; etc

[rancid crypt]

If i want to use a plugin in all other servers. It's good if i develop one plugin in bungeecord ? or i can add one by one plugin in all servers ?

[bold wharf]

This is the channel for velocity, not bungee; and it depends, if you can do everything on the proxy that generally makes a good chunk of sense but that's not always possible or sometimes it's just easier/more viable to be on all the servers

[rancid crypt]

Sorry, i think the problem can transform for velocity too

Ok thank you ^^

[topaz geyser]

Need help registering a velocity command, I'm doing this correctly, right? https://www.toptal.com/developers/hastebin/uxeseruxiy.kotlin

[oblique haven]

No you need to have the result of the “build()” function as the command meta

You can’t just cast it

[topaz geyser]

Thank you! I'll try that

[maiden hawk]

So, can I integrate Spring into my Velocity plugin?

[topaz geyser]

So I tried that, and it still doesn't seem to work

no errors

plugin is registered too

[oblique haven]

Show me the code

Like the whole file

Not just a snippet

[turbid jay]

Hey. Is it possible for a velocity plugin to read the hostname that the user uses to connect to the server?

[round quiver]

Hey, a questions, is there a way in velocity to do sth. like sending a PacketPlayOutCustomPayload to send the player some message over PluginMessaging?

[civic tiger]

Hey, how can you enter something in a config in a Velocity plugin and read it out?

[coarse topaz]

It is, see the InboundConnection class for such methods

[worthy smelt]

Does Velocity support 1.18?

[half locust]

yes

[nova sparrow]

I love velocity!

🤤

[opaque escarp]

Is there a possibility to integrate Configurate 4 into Velocity and deprecate the use of Configurate 3 as happened with text and adventure in Velocity 1.1.x?

[wary tiger]

It's entirely possible to shade the configuration library you want to use into your plugin. There's very little downside.

[valid gazelle]

this has to be something obvious, but i'm trying to build velocity with ./gradlew build but the file build/libs/velocity-3.1.2-SNAPSHOT.jar is 261 bytes, with only a META-INF/MANIFEST.MF file in it and that's it

[thick bramble]

go in proxy/build/libs

[oblique haven]

proxy/build/libs/velocity-3.1.2-SNAPSHOT-all.jar how bout this file

[valid gazelle]

oh

oops

[oblique haven]

make sure to specify -all otherwise people will come in here and talk about how it won't start

[valid gazelle]

yep that one works

[oblique haven]

sweet 👍

[opaque escarp]

I do that currently, I mean that Velocity integrates Configurate 3, which is a configuration library that already has a more current, better and stable version

[steel dagger]

https://bin.birdflop.com/uvudamenug.xml
I have no idea what the issue is but im getting this error
Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.1.0:shade (default) on project VelocityJoinLeaveMessages: Error creating shaded jar: null

[bold wharf]

update maven shade 🤷‍♂️

otherwise, can't really say as there ain't too much info there

[steel dagger]

anyone know a tutorial on making a config for a velocity plugin idk how toml works

[oblique haven]

you don't have to make your config in toml

[steel dagger]

how could i in yml then since i know the way i do for spigot plugins won’t work sine it uses bukkit api

[oblique haven]

https://github.com/SpongePowered/Configurate/wiki

[wind pebble]

Hi!
How can i dispatch command in console from code?

[native oasis]

Hey, I was wondering if it is possible to send data between servers, for example: A request Velocity -> PaperMC and PaperMC -> Velocity

[rich hawk]

plugin messaging

[native oasis]

Thank you

That helps alot!

[craggy pecan]

Pass the console command source to CommandManager#executeAsync

[native oasis]

Is there a way to get all network servers?

[oblique haven]

What do you mean by that

Like get all the registered servers?

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/ProxyServer.html#getAllServers()

[dusty mesa]

Is https://jd.velocitypowered.com/1.1.0/com/velocitypowered/api/event/connection/DisconnectEvent.html the correct event for when the player leaves?

[elfin snow]

Anyone know which event I have to use to change which server the player connects to? seems like PostLoginEvent or LoginEvent doesn't have a .setTarget method or something

or should I use LoginEvent and run
event.getPlayer().createConnectionRequest(someserver).connect()

[burnt dragon]

choose initial server event

[elfin snow]

Thanks!

[steady trellis]

i havent touched velocity for like a year, is there any documentation on the config api?

[oblique haven]

https://github.com/SpongePowered/Configurate/wiki

[steady trellis]

gracias

oh no

it's still configurate

[oblique haven]

it is yes, but that's just what is bundled

feel free to use your own

I think snakeyaml is open sourced and publicly available

so is Jackson, gson, etc...

[steady trellis]

do people use configurate like

commonly

[oblique haven]

not sure, I use jackson or gson

jackson yaml is pretty solid if you want yaml configurations, I prefer json personally

        VelocityConfiguration configuration;
        try (BufferedReader reader = Files.newBufferedReader(configurationPath)) {
            configuration = new Yaml(
              new CustomClassLoaderConstructor(VelocityPlugin.class.getClassLoader())
            ).loadAs(reader, VelocityConfiguration.class);
        } catch (IOException | YAMLException exception) {
            JsonLogger.error("Error loading configuration: ", exception);
            this.server.shutdown(Component.text("Failed configuration load."));
            return;
        }``` this is what we use in production actually

idk if this is standard or the recommended way but it's not bad

[steady trellis]

ahhh i see

legacy ip forwarding doesn't support the velocity in paper.yml does it?

[oblique haven]

correct, that's for modern forwarding

[steady trellis]

gotcha

[steady trellis]

is there a method that gets u the main container or the data folder

[oblique haven]

Yep

Look at the “getting started” page of the documentation section of the website

https://velocitypowered.com/wiki

I think

[steady trellis]

https://velocitypowered.com/wiki/developers/api-basics/

there it is

xD

[oblique haven]

Yee

[steady trellis]

thank u :d

[oblique haven]

No problem

[steady trellis]

there's no toml configuration loader?

[bold wharf]

Well, the library is there, at least some aspect of it

configurate exists

[coarse topaz]

Configurate is really good tbf

[steady trellis]

configurate is built in right because fixed did say it's bundled

[bold wharf]

yes

[steady trellis]

epic

[oblique haven]

But you don’t have to use it if you don’t want to

It just decreases final jar size - but if you don’t care about storage or this is personal it really doesn’t matter

There’s a few good toml loaders out there

If you want a reference on how to use configurate for toml, velocity is open sourced so you can see how it does it

[steady trellis]

ahh alright epic, i may just stick to yaml for rn 😅

doesnt velocity have like annotations for keys or am i thinking of something else

"Expose"

[steady trellis]

how do yu determine whether a server is online with RegisteredServer#ping

if throwable is not null then server is offline? else its online?

[pastel bone]

is there a TabCompleteEvent alternative to use on 1.12.2 and above?

[craggy pecan]

No, the client now handles suggestions mostly on its own

Use the appropriate methods on Command or add a suggestion provider to Brigadier nodes

[pastel bone]

Okay Thank you

[tawny hollow]

Velocity works on 1.18.1?

[oblique haven]

Yep

[limpid void]

where download dev velocity?

[oblique haven]

I think velocity has a ci you can download it from, or you can just build it yourself

[oblique haven]

git clone [e-mail]:PaperMC/Velocity
cd Velocity
./gradlew build
# success```

[steady trellis]

how do you make a command source run a command?

found it

its CommandManager#executeAsync right

is it possible to edit single strings in a component? i.e. i have a placeholder in a string and i want to replace that string with a clickevent

for example someone inputs in a config file

format: {back} Test {forward}```
I could do a component and replace back and forward with their specific characters and click events?

oh it's replaceText i think

[burnt dragon]

yup, that's the set of methods to use

note that you're better off just doing the placeholders before you have a component with a tool like minimessage

[steady trellis]

ahh epic! is there a documentation on minimessage on kyori's website i assume

[burnt dragon]

yup

[atomic leaf]

https://docs.adventure.kyori.net/

[steady trellis]

epic! thank you :d

[waxen mirage]

Hello, is there any equivalent to ```java
|ChatColor.translateAlternateColorCodes('&', SomeString);

[bold wharf]

use the legacy component serialiser

[limpid void]

a where to pick up the jar file?

after I collected

[rich hawk]

proxy/build/libs

[limpid void]

there are two of them, which one to take to run through
Java -jar velocity.jar?

[bold wharf]

I mean

I'd guess whichever jar file is bigger

[steady trellis]

i am assuming the legacy component serializer wont work for hex colors

since its legacy

[bold wharf]

it does given spigot shoe horned that crap in

[steady trellis]

ahhh alright thank you

[steady trellis]

is there an event that gets the player on login without sending the login message

so i can check for perms

i think its chooseinitialserverevent i hope

[verbal tartan]

is there not a change server event?

[valid gazelle]

the way i did it in my plugin was using ServerConnectedEvent, and then checking event.getPreviousServer() which is an Optional<RegisteredServer>

[verbal tartan]

how would I get the server being connected to

also what is an Optional?

Can I get it to return the server name

nvm I can just getcurrent server

but also returns an Optional

[valid gazelle]

look up how to use Optional in java for more info, but you can use .isPresent() and .isEmpty() to check if it has a value, and then after checking that, you can use .get() to get the actual value

[verbal tartan]

is value in int or string I can't tell from docs

[valid gazelle]

it returns an Optional<RegisteredServer>, so after checking if it has a value, then using .get() would give you a RegisteredServer

[valid gazelle]

insteafd of doing this you could do .getServer() in the ServerConnectedEvent to get the server that they just connected to (this one is just a plain RegisteredServer)

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/player/ServerConnectedEvent.html

[verbal tartan]

I see

thanks

[steady trellis]

ahh alright ty all :d

how do you use RegisteredServer.ping() properly? is it .whenComplete?

[bold wharf]

well, that's one way

suggest reading up on Futures

[steady trellis]

i've been looking into it but i cant figure out how to properly loop through multiple server pings because im trying to make a /glist command that shows whether a server is online or offline as well

serverping just tells me if its off or on but the registeredserver gives me the server information

[analog dew]

Pings are not synchronous, it takes time for Velocity to ping a server

Most likely you want to get info for each server from RegisteredServer, ping all the servers then wait for responses to all those pings

[bold wharf]

just create a list of futures or something, think there is even a Future util which will let you wait until you have a list of them completed

[maiden hawk]

So when I annotate my class with @Plugin, fill in the info package and then open the jar in zip viewer,
velocity-plugin.json appears out of nowhere with the info from the annotation.
This seems very interesting, how does it work?

[rich hawk]

annotation processor

[maiden hawk]

but for that, I would need to have some kind of velocity plugin installed when building right?

[rich hawk]

https://github.com/PaperMC/Velocity/tree/dev/3.0.0/api/src/ap/java/com/velocitypowered/api/plugin/ap

[maiden hawk]

thanks, gonna look into it, seems very interesting

[rich hawk]

It’s the annotationProcessor dep

[maiden hawk]

So that just get's called by my build system automatically at compile time?

[rich hawk]

you add the api as compileOnly and annotationProcessor

Yes

[maiden hawk]

hmm

thanks

[rich hawk]

#velocity-github ???

[half locust]

looks like someone is setting off a code reformat on the entire bloody project..?

[elfin snow]

anyone knows how to load an integer from a yaml file? (YAMLConfigurationLoader)
rootNode.getNode("redis.port").getValue(new TypeToken<>() {}),
Doesn't seem to work

[rich hawk]

@agile ore

[agile ore]

ignore me

im doing that accidentally

sorry, i forgot the compare thing

[steady trellis]

yup! i figured it out haha thanks

[steady trellis]

yeah! had to figure out how to do it with hashmaps

[elfin snow]

[19:17:57 ERROR]: Couldn't pass ProxyInitializeEvent to serverstatus
com.zercraft.server_status.internal.redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool

        at sun.nio.ch.NioSocketImpl.connect(NioSocketImpl.java:567) ~[?:?]

Any idea what's happening here? redis isn't able to connect and the host format looks kinda weird but idk, worked fine on bungee but fails on velocity

[bold wharf]

UnknownHostException

[rich hawk]

pterodactyl?

[bold wharf]

eeeerrrrr

[rich hawk]

make sure that the Redis server is up & firewall etc

[elfin snow]

Yeah I know, but using 127.0.0.1 or the actual ip fails, worked fine on bungee and same config works fine on paper servers running on the same machine

[elfin snow]

nah just starting the server from the shell

[bold wharf]

I mean

I can't tell you WHY you got that exception

but

you got that exception

[elfin snow]

Yeah I get you 😅 I'm just confused as everything seems fine, service is up, everything else can contact it fine, can telnet on it,

[19:17:57 INFO]: Listening on /[0:0:0:0:0:0:0:0%0]:25565
not sure if that's normal but guess that's just the ipv6 showing,

also have never seen an UnknownHostException with the message formatted like that, "{redis{ip= etc.."

[bold wharf]

well, I mean

it shouldn't be

that suggests that something passed in the redis instance or something, but 🤷‍♂️

[elfin snow]

yeah, wonder if it parsed the host wrongly or something

[rich hawk]

does your Redis instance have ipv6 enabled?

[elfin snow]

should be, config says:

The server only accepts connections from clients connecting from the

IPv4 and IPv6 loopback addresses 127.0.0.1 and ::1, and from Unix domain

sockets.

[rich hawk]

what do you have it set to?

[elfin snow]

Found the issue, was using

rootNode.getString("redis.ip")

instead of

rootNode.getNode("redis").getNode("ip").getString();

🙃

[maiden hawk]

It looks like that guy just ran IntelliJ cleanup on it

[valid gazelle]

speaking of that someone should do that, looking at !something.isPresent() annoys me

hehe

[pastel bone]

Is it possible to Register Brigadier Commands on runtime or do i HAVE to register them on initialization

It seems like my command just wont register...

@EventHandler
  public void onPrexorCommandRegister(CommandRegisterEvent event) {
    CommandInstance instance = event.getInstance();

    LiteralArgumentBuilder<CommandSource> parent = LiteralArgumentBuilder.literal(
        instance.getLabel());

    if (instance.hasChildren()) {
      instance.getChildrens().forEach(children -> {
        String label = children.getLabel();
        parent.then(LiteralArgumentBuilder.literal(label));
      });
    }

    PrexorProxy.getInstance().getServer().getCommandManager()
        .register(new BrigadierCommand(parent.build()));
  }

I already debugged everything -> LiteralCommandNode is setup perfectly everything how i want it to be It's just that in game it tells me Unknown Command

[steady trellis]

why use brigadier

[valid gazelle]

Why not

[pastel bone]

idk actually

[steady trellis]

why

[valid gazelle]

because it has argument parsing

[pastel bone]

So now the command is working but it wont suggest the command itself? I have to type it myself any idea why?

[steady trellis]

hmmm

i have no idea how brigadier works but there is documentation on velocity's website

https://velocitypowered.com

[pastel bone]

yes this documentation is crap if we're being honest hahaha The test's in the source has helped me so far

I think I'll try my luck using SimpleCommand

[pastel bone]

PrexorProxy.getInstance().getServer().getCommandManager().register(
        instance.getLabel(), new PrexorVelocityCommand(instance)
    );

I don't understand what I'm doing wrong hahahaha The command just won't register

(I'm now using SimpleCommand)

Sorry the command is getting registered but it just won't suggest it

[oblique haven]

Make sure you have permissions setup properly

[pastel bone]

What exactly do you mean by "setup"

[pastel bone]

I mean I can execute the command itself but it just won't suggest it so I have to type it out entirely

[oblique haven]

That’s odd

[steady trellis]

are u registering on init

proxyinitialize event

[pastel bone]

Yes, I mean would the command even work in the first place if I'm not doing it on Init

Is there even a way to register command on runtime?

[steady trellis]

try using a commandmeta instead of a label call

[pastel bone]

Ight gonna try that tomorrow, thank you

[bold wharf]

I mean, afaik there is nothing preventing ou registering commands whenever you want

Just, note that it won't show in tab completion unless the backend server resends the command definitions to the client

[pastel bone]

So that's my Problem

Can I force the server to resend the command definitions?

[bold wharf]

don't mention

from paper, there is a method on Player

but you'd need to send a message to the server to do that

[pastel bone]

I know there was a way to do it in bucket but that won't work in velocity

Bukkit*

[pastel bone]

Sounds complex you don't got any code example by any chance do you?

[bold wharf]

stop mentioning

[pastel bone]

Ah sorry hahah

[bold wharf]

You'd need to have a plugin on the server and use plugin messaging or something

[pastel bone]

Hm okay will try that tomorrow thanks for the help

[pastel bone]

Both approaches didn't work unfortunately I tried using ComandMeta instead of String and I've updated the Commands for the Player

[steady trellis]

what mc version are u on

[pastel bone]

1.17.1

I legitimately don't get what I'm doing wrong.... like why isn't it suggesting my commands 😂

[craggy pecan]

electroniccat already told you, new command registrations aren't sent right away to all clients. The proxy waits for a new command tree to be sent by the backend server (e.g. during server switch) to inject its own commands

This is a wontfix since live command tree updates require lots of memory, and arguably this is a bit of an edge case

[magic forum]

Hello, I'm encountering io.netty.util.IllegalReferenceCountException after handeling a packet

It seems like it's getting double deallocated somewhere

o shit, just fund out why. Sorry for bothering you

The channelRead function in Minecraftconnection.java automatically deallocates but since I already did that on my side, it throws that error

[maiden hawk]

Agreed. However posting a huge PR without explanation that is almost impossible to review, is indeed kinda bad.

[valid gazelle]

yeah

That one PR was doing a little more than. Just reformatting like that though

[maiden hawk]

If I use "FORCE_ONLINE" in preloginevent, will a new player receive an online mode uuid? Or will it still be generated using offline mode method?

[maiden hawk]

it does.

[pastel bone]

For test purposes I created a "TestCommand" and registered it on the ProxyInitializeEvent. The Command still doesn't get suggested if I try to tabcomplete it

Could it have something to do with that I'm using Velocity and Tuinity?

[pastel bone]

Alright. For anyone ever encountering this problem you have to set "announce-proxy-commands" to "true" in velocity.toml

[bold wharf]

that's on by default...

[pastel bone]

well I definitely didn't turn it off... Maybe it was set to false by default in older versions perhaps?

I really have no clue

[craggy pecan]

Nah, has always been true

[steady trellis]

the fact that that was the problem is so sad and i am sorry u had to deal w such pains

[magic forum]

Bruh, why is the modern forge support taking so long?

It was 5 major mc updates ago modern forge came

[rich hawk]

search for modern forge here

You’ll figure out why

[magic forum]

But only basic support like joining a server?

No need for re-syncing

It's only a small modification in the code and it's done

I have already got it to work and it took about 3-4 hours

Can't understand what's taking so long

[analog dew]

Any sane implementation needs changes to Forge as well as to Velocity, and people are busy

[bold wharf]

no need for resyncing

sigh

yes, if you wanna go for a half baked solution which has many dozens of issues with server switching,etc, yea, sure, it can "work"

if you wanna actually have cross server switching which actually works long term and allows shit to handshake properly vs the years of bastardisation which has consistently caused issues, no, the client needs to support re-handshaking in some respect and resyncing data, etc

[long kelp]

hello i am new to velocity development. coming from bungee/spigot development. i am getting this stacktrace and i am unsure as to what to do. cant find anything relating to it on the docs

[bold wharf]

your plugin is missing the file it says

depends on how you're building the plugin, make sure that you're using gradle or maven

or, if you're using the IDE thing, make sure that you've at least got annotation processors running

(also, make sure that you have the annotation on your main class)

[long kelp]

figured out i needed an annotation processor

except im confused on how i actually implement one

[bold wharf]

velocity includes the annotation processor

like, it's part of the API

do you have the Plugin annotation added or whtever it was?

how are you building the jar?

[long kelp]

maven

[bold wharf]

make sure that you're running the package task and not building with your IDE i'd guess

[long kelp]

if i try to do that it just tells me
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project velocitytest3: Compilation failure

[bold wharf]

if building with maven blows up then you've not been building with maven

[long kelp]

however it does build if i use jar

[bold wharf]

there is a way to see the full output of the task

[bold wharf]

Well, there you go

in the mven config set the version of java to something newer

(or, update the compiler plugin)

(I have a dream where maven stops using multi year old plugins by default...

[long kelp]

maven is a mess in itself

i probably should learn gradle

[bold wharf]

yea, I mean, gradle has its own set of issues, but, I mean, outside of tryna learn it it seems to generally be a much smoother experience

[long kelp]

true

half of my bungee and spigot plugins are maven so i just got used to it

and the plugin i need to make a velocity port of is maven so thats fun

[nova radish]

Why is it that this method doesn't exist but it does on javadocs? https://i.imgur.com/Tbr0Lx3.png

I'm using 3.0.1

[maiden hawk]

Sorry but why do you think that getCommandManager does not exist?

[bold wharf]

are you looking at the JDs for 3.0.1?

published jd's are for 3.1.2-snapshot

[nova radish]

My apologies, I mean getCommandMeta.

[maiden hawk]

and how do you know that it exists on the javadocs? The thing you showed is about getCommandManager

gimme a sec gonna check JD

wait

which version do you use?

[nova radish]

previously I was using 3.0.1

but I was looking at 3.1.2-snapshot javadocs by accident

I bumped the version to 3.1.0

[maiden hawk]

oh ok

[nova radish]

and it worked

[bold wharf]

the thing was added in 3.0.2

[queen pasture]

is there any plugin similar to jpremium for velocity?

https://www.spigotmc.org/resources/■-jpremium-■-authorization-plugin-■-automatic-login-premium-■.27766/

[agile ore]

Mojang has one, it's called online mode

[queen pasture]

breh

[quick quail]

is there a way to get the proxy's minecraft version?

[quick quail]

found it

[maiden hawk]

fastlogin does something similar, however if an online player changes their nickname they lose their stuff

[signal jasper]

building my project (with annotation-processor and api 4.0.0) generates a jar with a velocity-plugin-info.json

trying to load it within the latest velocity (3.1.2) gives an error

that the velocity-plugin.json files doesn't exist

[maiden hawk]

uhhh shouldn't it be velocity-plugin.json instead of velocity-plugin.info.json ?

[signal jasper]

renaming velocity-plugin-info.json to velocity-plugin.json doesn't solve the issue

as it's now complaining about invalid json structure

[signal jasper]

yea, but that's the file that it's generating

[maiden hawk]

do you use gradle or maven?

[signal jasper]

gradle

using an auto generated build.gradle by the minecraft dev plugin

https://www.toptal.com/developers/hastebin/qopicicefi.rb

[maiden hawk]

wait

I see the issue

[signal jasper]

ye?

[maiden hawk]

you are using velocity api v4 on velocity 3.1.2

[signal jasper]

yeah, I wasn't able to use api v3.1.2 nor velocity 4

[maiden hawk]

why wouldn't you?

[signal jasper]

1. can't find api v3.1.2 in any repo (paper, velocity, central)
2. can't find velocity 4 (download page, repo)

[maiden hawk]

just do

    annotationProcessor 'com.velocitypowered:velocity-api:3.1.2'

    compileOnly 'com.velocitypowered:velocity-api:3.1.2'

in your dependencies

it works for me

[signal jasper]

what repos are you using

[maiden hawk]

    maven { url 'https://nexus.velocitypowered.com/repository/maven-public/' }

make sure to use 3.1.2 not v3.1.2

[signal jasper]

[maiden hawk]

this is... odd

maybe try to clear your local cache?

[signal jasper]

alright

[maiden hawk]

my bad, 3.1.2 does not exist, use 3.1.0

[signal jasper]

welp

[signal jasper]

still can't find it

(talking about 3.1.0)

wait no

[agile ore]

Try using the paper repo, might've moved over there

[signal jasper]

it can only not find the ap now

[warm solar]

repositories {
    maven { url = uri("https://papermc.io/repo/repository/maven-public/") }
}
dependencies {
    compileOnly("com.velocitypowered:velocity-api:3.1.1")
    annotationProcessor("com.velocitypowered:velocity-api:3.1.1")
}
``` i've been using this

[signal jasper]

ok let me try that repo

pretty sure I've already tried that

but let's give it a go

nope

also doesn't work

can't find the ap this time either

where's 3

ok using 2.0 works

but now it can't find any events

nvm they just moved packages

[maiden hawk]

uh

[signal jasper]

yes it works now

let me try building

[maiden hawk]

the annotation processor has the same name like api

[signal jasper]

nvm lol now the ap crashes lol

[signal jasper]

huh?

[maiden hawk]

can you please send your build.gradle again? (the new one)

[maiden hawk]

try now: https://www.toptal.com/developers/hastebin/wikezabedi.rb

btw, the paper repo might be redundant

[signal jasper]

ffs that works

thanks so much!

[maiden hawk]

np

[signal jasper]

let me try running it now

nice it works now

just a lil' encoding problem now :p

thanks for the help

[maiden hawk]

np

May I ask what is that client?

[signal jasper]

badlion client

[maiden hawk]

hmm, ok.

Hi, how can I register plugin messaging channel without colon? I need it for FastLogin becase FastLogin use plugin messaging channel force.

[maiden hawk]

are you sure it uses that channel? To my knowledge, bukkit should also throw an error if you attempt to do that

fastlogin has a velocity port, lemme check

well according to their source code, they do not use channel force at all but only
FastLogin:ch-st
FastLogin:succ

[thorn bronze]

There is a channel named force: https://github.com/games647/FastLogin/blob/main/core/src/main/java/com/github/games647/fastlogin/core/message/LoginActionMessage.java

[thorn bronze]

I've tried FastLogin:succ but it return nothing.

[maiden hawk]

then try FastLogin:force

[bold wharf]

the protocol literally does NOT allow channels to exist without a :

[thorn bronze]

Tried, but nothing received. I only received: fastlogin:succ

[maiden hawk]

yup, that's why it is really odd

[maiden hawk]

wait, are you using fastlogin on velocity?

[thorn bronze]

Yeah

[maiden hawk]

Then it probably uses lowercase name

[analog dew]

If you look at their code for more than 5 seconds, you'd see that they combine it with a namespace everywhere it gets used

[maiden hawk]

and that makes sense, the fastlogin port for Velocity does not use the force channel

[maiden hawk]

ikr?

[thorn bronze]

I've tried it in lowercase

[maiden hawk]

what? fastlogin:force? As I've said, as far as I can see, fastlogin on velocity does not use that channel.

[thorn bronze]

Yeah, exactly: fastlogin:force

[maiden hawk]

they only use succ and ch-st

not force

or at least, I cannot find it

they only register these channels:

        this.successChannel = MinecraftChannelIdentifier.create(plugin.getName(), SuccessMessage.SUCCESS_CHANNEL).getId();
        this.changeChannel = MinecraftChannelIdentifier.create(plugin.getName(), ChangePremiumMessage.CHANGE_CHANNEL).getId();

[thorn bronze]

Yeah, I receive only fastlogin:succ. But it doesn't contain any other data like username.

[maiden hawk]

[thorn bronze]

I need to add FastLogin compatibility for my Auth plugin in Velocitypowered.

[maiden hawk]

well GL then

[thorn bronze]

😩

[maiden hawk]

tho if your auth plugin is on velocity and fastlogin is also on velocity, why don't you just hook into it?

[thorn bronze]

Does FastLogin for Velocitypowered has API?

[maiden hawk]

no idea

[thorn bronze]

I didn't found any documentation

[agile ore]

it should

[maiden hawk]

i mean in worst case scenario you can just hook into it and hope it won't break with future updates

[thorn bronze]

Ok, I found these events: VelocityFastLoginAutoLoginEvent, VelocityFastLoginPreLoginEvent, VelocityFastLoginPremiumToggleEvent but none of these events run when connecting to the server.

This is how it looks like:

    @Subscribe
    public void onTest(VelocityFastLoginAutoLoginEvent e) {
        main.getServer().sendMessage(Component.text("Test message"));
    }

I tried also: FastLoginAutoLoginEvent, FastLoginPreLoginEvent, FastLoginPremiumToggleEvent

[thorn bronze]

When I use e.setResult(PreLoginEvent.PreLoginComponentResult.forceOnlineMode()); in PreLoginEvent it changes UUID of player.

Is there any way to keep same player UUID?

[maiden hawk]

you can store it somewhere or generate it on
GameProfileRequestEvent

if you want to know how uuids are generated defaultly take a look in velocity src

But iirc it is done by taking bytes from string OfflinePlayer:player_name and then making uuid from it

[lost cypress]

Hey everyone 😃

I'm looking to remove certain commands from the 1.13 'command suggestion' system through Velocity.

This event is definitely related:
https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/command/PlayerAvailableCommandsEvent.html
...but it contains no methods (unless I'm missing something) that allows me to cancel the command from being sent to the player.

Any assistance would be much appreciated. Thank you!

[twin ingot]

Hi, I'm creating plugin for authentication tokens like BungeeGuard, and my question is how I can do it on velocity?

[lost cypress]

what stage are you currently at?

I think BungeeGuard is built in to velocity btw :)

[twin ingot]

Now i have all created for bungeecord and spigot.

[twin ingot]

i know about this, but I wand create own plugin

[fierce tundra]

Does anyone here know of or have documentation on custom packets via the proxy; specifically keepalive packets?

[craggy pecan]

You access the root command node with getRootNode() and mutate it as you want

[steady trellis]

https://wiki.vg/Protocol

maybe thatll help

[lost cypress]

Is it possible to hide it for a certain player?

[craggy pecan]

You can get the player for which the root node is for with getPlayer(). Do your own logic with it

[dusk timber]

WTF 3 files with one data

why?

papermc code

[burnt dragon]

that's how patches work

patches show the code that surrounds the changes you've made, meaning if you make changes to similar areas of code in different patches then you'll get stuff like this happening

also, #paper-dev

[dusk timber]

you can somehow ask the developers to correct the translations a little, they have a color in the code at the beginning of each message of the type chatColor.RED

можно как то попросить разработчиков чтобы они немного подправили переводы, у них в коде указ цвет вначале каждого сообщения по типу chatColor.RED

because it is strange to do this if you can set the color of the text inside the message itself

потому что странно так делать если внутри самого сообщения можэно задавать цвет текста

and sometimes you have to call the server like §fLobby§r

и иногда приходится называть сервер, например §fLobby§r

[fierce tundra]

Ooo it looks as though it will help quite a bit, thanks!

[steady trellis]

its not recommended to use chatcolor over namedtextcolor i believe

[thorn bronze]

Hi, is it possible to get which player sent message via plugin messaging channel?

I found player is stored in getSource() and getTarget() but I don't know how can I get the player from there.

[bold wharf]

see the JDs

iirc those methods return some object which contains the relative thing

may need to cast towards something else from that result

[thorn bronze]

I looked at JDs but I didn't found anything useful. https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/messages/ChannelMessageSource.html

[bold wharf]

don't mention

see the known subinterfaces

[thorn bronze]

Sorry, I forgot.

I found Player and ServerConnection subinterfaces.

But I didn't found anything useful there.

[bold wharf]

instanceof Player

[thorn bronze]

Worked, thank you so much!

Actually, it doesn't work. The getSource() is not instanceof Player.

[bold wharf]

or, well

that assumes that the client sent the message

if it came from the server, see the ServerConnection

[thorn bronze]

I'm sending message in bukkit plugin message channel using: p.sendPluginMessage(main, "test:plugin", out.toByteArray());

[bold wharf]

oh, so, yea, server connection

[thorn bronze]

Now worked, thanks.

[long kelp]

my command just doesnt work. it just says it doesnt exist

this is all the code

im stumped

ive looked at references, everything

cant find anything that works

[oblique haven]

@long kelp can you show us your imports

In your plugin source

[long kelp]

theres no errors in the editor

and no stacktrace

infact heres it loading just fine

but when i do the command

[oblique haven]

That’s the wrong Subscribe annotation

You’re using one from google’s event bus - not the velocity one

Since this is so common it might be nice if velocity threw a warning for methods tagged with this

[long kelp]

oh

yeah i see now

thanks

and thats worse

[slate hamlet]

which interface is your command implementing?

[long kelp]

i figured it out

[long kelp]

i was using Command but i tried SimpleCommand and its working for the moment

[slate hamlet]

Yea thats how the command system works

[long kelp]

rn im just referencing off source code i can find on the internet lol

cant really find any forums threads relating to issues with this stuff

[slate hamlet]

https://velocitypowered.com/wiki/developers/command-api/

Here are some basic references for the api

[long kelp]

those references didnt do much for me

[slate hamlet]

At least the command api is explained there correctly xdd

[long kelp]

true

setting up the plugin tho

thats a lot different

[slate hamlet]

Really?

[long kelp]

yeah

[slate hamlet]

It looks correct to me

[long kelp]

it was a lot more of a struggle than just popping in some dependencys

mainly cause my ide refused to build it

[slate hamlet]

What was the issue?

[long kelp]

unsure

just knew that my ide was like what is this garbage

and decided not to compile

it did eventually work after a bit of fiddling with the settings

velocity work is a lot different than bungee work

and i have to convert an entire bungee plugin over to velocity soo

yikes

[slate hamlet]

After you get the basics it's much easier and cleaner to work with the velocity api xD

[long kelp]

true

it was kinda the same with bungee and spigot

its hard at first but once you have some references and some knowledge on how they work its pretty straight forward

[scarlet spruce]

How would I go about executing a console command on a proxied server? (knowing that sometimes the server could be empty)
Tried plugin messages & no luck, or I'm just really bad with them but onPluginMessageReceived just never gets called on the spigot server, despite me in the proxy plugin calling getServer("factions").get().sendPluginMessage(MinecraftChannelIdentifier.create("test", "testchannel"), out.toByteArray());

[bold wharf]

if the server is empty you can't

otherwise you'll need to make sure that your plugin message channels are registered properly, idk how velocity deals with that one

if you need reliable message sending, use a message broker

i.e. rabbit, redis, etc

[scarlet spruce]

Thank you, will look into redis.

[long kelp]

anyone know why im unable to load my config

Exception in thread "main" com.google.common.util.concurrent.ExecutionError: com.google.common.util.concurrent.ExecutionError: java.lang.NoClassDefFoundError: org/spongepowered/configurate/hocon/HoconConfigurationLoader

[burnt dragon]

velocity only ships the toml configurate

you need to shade/relocate hocon i think

[long kelp]

im unsure of what im suppost to do

i did exactly as followed on the docs for configurate

[burnt dragon]

you are supposed to shade and relocate the hocon loader

[long kelp]

i dont even know what that means

excuse my terrible java skills im still learning

[burnt dragon]

plenty of online guides/tutorials for how to shade and relocate libraries for your build tool

[rich hawk]

it has hocon, gson & yaml

errr, I think that’s configurate v4? velocity only has 3.x iirc

[nova notch]

Can someone from the development team update the velocity site, please? Site currently says that the newest supported paper version is 1.17.1, but that's not true, it should be 1.18.1.

[bold wharf]

that site is deprecated

i'll have to see what the plan for it was

[nova notch]

Ah, cool.

Wait, github points you to the site. So how is the site deprecated, if it's the main download point for the jar?

[bold wharf]

fun area where much of our own web content needs redoing, offering downloads on the velocity site directly makes little sense given our own downloads page which is more smrt

I think in the meantime I'll just make the dev build button link to our own downloads page and update the text

[elfin snow]

Anyone know how I merge player count for sever lists when I have multiple proxies? Can I just return another number on the ping or will sever lists think I'm faking player count then?
(already got player count synced to each instance)

[valid gazelle]

well, what's the server lists' methods of detecting if you're fakng player coumt

[elfin snow]

Good question haha, was thinking it maybe did a query to get player list

[bold wharf]

The proxy substitutes the info it has for some stuff in the correct config, iirc

otherwise you'd need to like, sync counts across proxies

i.e. store counts on redis

and then populate the info in the events

[elder quarry]

I'm trying to make custom events, which Event class do I need to import?

[robust mural]

https://velocitypowered.com/wiki/developers/event-api

[elder quarry]

I'm on there, doesn't tell you which class to use...

[robust mural]

Look at "Creating an event class"

[elder quarry]

it says implements Event, which Event class?

[robust mural]

From velocity

[elder quarry]

I though so too, but...

[robust mural]

Oh

I think the docs are old..

I've looked in the other events, you don't need to implement anything

[elder quarry]

Reading the docs again it says under the example;
You'll notice that your events don't need to extend or implement anything. They just work.
But in the example they do implement Event... kinda annoying

[steady trellis]

really old example. u'll see addListener takes an object not an event instance

u just need an instance of a class with @subscribe on the methods

[rich hawk]

It doesn’t tell you to implement anything?

[visual adder]

every few hours, the server breaks and people cant join

it says this error

[fleet sail]

message.txt by @visual adder: https://paste.gg/7087b6583b9a41629eb0f95e2be9008f

[visual adder]

been happening since auth change by mojang

how do i fix? it's killing my server

[bold wharf]

something apparently managled a packet

given that the auth api at that phase is basically 100% irrelevant, I'd imagine it's some plugin on the server

[visual adder]

any idea how i would go about figuring out which plugin it is

as this only occurs completely randomly

lol

then itll only last a few min, 30min to an hour and its done

[bold wharf]

cleanly, no

most things are often a binary search or modifying the server to try to detect such states

[visual adder]

that doesnt sound good

[visual adder]

So what steps should I realistically take to fix this?

Find a dev that can modify the server to detect such states?

is it this?

[bold wharf]

yes

[iron sundial]

how can you get the server address a player joined with?

[fringe thicket]

Should be in the logs. If not, there are a couple of other files laying around within the server that should tell you.

not talking about plugins, but that could tell you too if it's meant to

[craggy pecan]

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/InboundConnection.html#getRemoteAddress()

[round gulch]

So Im struggling with something. Im using the essential player plugin for velocity to handle my tablist and my global msgs. Ive succeeded in altering the source, compiling and running it on my server. But I am struggling to add color to the "join" messages.

The source is as follows, and I thought I could simply just add "&e" in front of it to change the color, so like :

private void connectNote(ServerConnectedEvent event){
    Player player = event.getPlayer();
    String sendMessage;
    if (event.getPreviousServer().isPresent()){
        sendMessage = **"&e" +** player.getUsername() + " has joined the "
                + event.getServer().getServerInfo().getName() + " world";

But ofcourse, that doesnt work. Can anyone help me along? 🙂

Cause this, will just output the msg like "&ePlayername has joined the XX world"

[atomic leaf]

[burnt dragon]

^ is probably what you're looking for

[burnt dragon]

Is it possible to not respond to a ping request (i.e. can I "pretend" that a server is offline)?

[ripe cobalt]

Does Velocity have a built-in basic messaging channel system like Bungeecord's default message channel?

And can the get virtual host method read from the proxy something like a random srv address (ex. play.server.com) entered by the player on the client?

[burnt dragon]

uh.. well, 1) gs4 isn't the server list ping and 2) im not asking in paper help :')

ah no, i meant for pings coming into velocity with the ServerPingEvent

[dense glen]

Ip?

[maiden hawk]

Not that I'm aware of. Try to see what happens when passing null to #setPing

[burnt dragon]

id be surprised if that worked but i suppose it's worth a shot

[maiden hawk]

How did it end up?

[burnt dragon]

haven't got a chance to test it yet, will keep ya posted

[maiden hawk]

ty

[valid gazelle]

I mean technically you could make your listener block for a minute or something so it times out

That's a horrible idea though

[light tendon]

Hello I am trying to convert BossShopPro bungeecord part to velocity, a PluginMessageEvent. I tried changing it to velocity functions and still doesn't work, The debug messages even dont show.
Here's the code:

    public void onPluginMessage(PluginMessageEvent e) {
        System.out.println("result - " + e.getResult());
        System.out.println("identifier - " + e.getIdentifier().getId());
        System.out.println("data - " + e.getData());

        if (e.getIdentifier().getId().equalsIgnoreCase("BungeeCord")) {
            DataInputStream dis = new DataInputStream(new ByteArrayInputStream(e.getData()));
            try {
                String subchannel = dis.readUTF();
                if (subchannel.equalsIgnoreCase("BossShopPro")) {
                    String type = dis.readUTF();
                    if (type.equalsIgnoreCase("Command")) {
                        String command = dis.readUTF();
                        server.getCommandManager().executeImmediatelyAsync(server.getConsoleCommandSource(), command);
                    }
                }
            } catch (IOException e1) {
                e1.printStackTrace();
            }
        }
    }```

[daring imp]

did you use the correct import for @Subscribe? Its not the google one. https://velocitypowered.com/wiki/developers/event-api/

[light tendon]

its the good import but no longer relevant

thanks anyways.

hi all, i am getting a weird Guice error with a Velocity plugin I'm trying to get to run (velocity-api:3.0.1 with the latest version Velocity 3.1.2-SNAPSHOT (git-7bd0f9ea-b114))

[17:05:05 ERROR]: Can't create plugin arcoviaproxy
com.google.inject.ProvisionException: Unable to provision, see the following errors:

1) [Guice/ErrorInjectingConstructor]: IllegalArgumentException: ArcoviaProxy does not have a container.
  at ArcoviaProxy.<init>(ArcoviaProxy.java:28)
  at VelocityPluginModule.configure(VelocityPluginModule.java:48)
  while locating ArcoviaProxy

this is literally the whole class, which leads me to believe i'm missing something super basic in my project setup, but I couldn't find any discrepancies while reading the docs

@Plugin(
        id = "arcoviaproxy",
        name = "ArcoviaProxy",
        version = "1.0.0",
        dependencies = {
                @Dependency(id = "luckperms", optional = true)

        }

        server.getEventManager().register(this, new ServerJoinListener(this));
    }
}

[rich hawk]

I don’t think you can register events in the constructor?

[dense sand]

oh

my god

yeah I read the section on ProxyInitializeEvent but I guess I decided to not comprehend it, thank you catching that

[woven stag]

is the massaging service api is same as bungee?

[ripe cobalt]

How does using the EventTask.async() method in Velocity's event handler work differently compared to not using it?

If I use EventTask.Async() , is there no blocking on player handling to do something that takes a long time like a web API?

So, you mean if I apply Thread.sleep(9999 Minutes) 100 times with EventTask.Async() , it won't cause any problems handling other players' events, right?

I was wondering if there is a similar function in velocity like intents of event api used in bungeecord.

[valid gazelle]

but doesn't velocity have no main thread

[maiden hawk]

??? Velocity does not have main thread

[maiden hawk]

ik that I'm annoying, but still not anything?

[burnt dragon]

haha nope, ill get to it and some point dw

will most likely just submit a PR to add the ability to prevent a ping if not

[maiden hawk]

[ripe cobalt]

What method should I use to check if a specific server is online among the registered servers to Velocity?

[bold wharf]

basically, ping it

[ripe cobalt]

Is ping() the only way?

[bold wharf]

Well, yea

only way to see if something is online is to make a connection to it, basically

unless you tracked that state yourself using some form of system

[ripe cobalt]

thanks sir

[maiden hawk]

well, before doing that, you could check whether there are some players on it

[oblique haven]

Does anyone have plans on writing the PR for protocol 758? I don’t think anything should change on the proxy end for it.

If not - I can write a simple one to just add the version to the list
