velocity-dev

[queen pasture]

but it uses a dependecy

called kyori-adventure-platform-bukkit

[oblique haven]

why not just ask clip to update it or port it?

seems like something he'd do

[queen pasture]

yea then i would need to wait for it im already halfway done porting im just tuck

[oblique haven]

PlaceholderAPI is a plugin for Spigot servers that allows server owners to display information from various plugins with a uniform format.``` wait whut

[queen pasture]

in this part

[oblique haven]

it doesn't have kyori-adventure-platform-bukkit, maybe delete it and see what goes wrong

then you'll know where it's being used and find alternatives

[queen pasture]

i mean i cloned the repo

[oblique haven]

okay

it doesn't have kyori-adventure-platform-bukkit, maybe delete it and see what goes wrong 🤷

then you'll know where it's being used and find alternatives

[queen pasture]

yea so got a couple of errors

[oblique haven]

now you know where it's being used and can find alternatives

[queen pasture]

hmm i'll check

damn its working

it was using adventure for the ecloud list command

i deleted the whole class lol

[oblique haven]

lol

[burnt dragon]

it's gonna be impossible to port it

the entire ecosystem depends on bukkit

[queen pasture]

nah

its possible

[burnt dragon]

yes it does, like every single expansion is gonna be using bukkit stuff

so you'll port it but it'll be useless as nothing else will work

[oblique haven]

I think he's forgoing existing expansions

[queen pasture]

i only need the math expansion rest my plugin will handle

[burnt dragon]

oh sure, so like the entire point of the plugin then :')

[oblique haven]

he's basically using it as an advanced replace("xyz", "xyz")

[burnt dragon]

you'd be better off just making a math minimessage placeholder, save yourself some time

[oblique haven]

or just use the js engine to do math which I'm pretty sure is what that expansion does

[queen pasture]

like i will limit the number of downloadable expansion

and put some custom coded expansion so that it will work like a smaller version of placeholder api on both bungeecord and velocity

it will be usefull in the future for accessing values across plugins

[tawdry sky]

what

[fossil sundial]

id must be lowercase and cannot contain spaces, numbers or special characters outside of -

[tawdry sky]

Ah, okay

Thank you

Still

ohh I think I know what might be the issue

[opaque escarp]

I was developing a placeholders plugin based on minimessage with support for Paper 1.18.2 and Velocity 3.1.2, if you want to see it, here it is https://github.com/4drian3d/MiniPlaceholders/

[jolly sandal]

Hi is there a way to make a player perform a command to my spigot servers directly without sending it to velocity

[fossil sundial]

Wdym? The command has to always pass through the proxy. If you choose not to handle it on the proxy/if there isn’t a registered command to take it then it will be forwarded to your current server

[jolly sandal]

Like I have created a guild system on my velocity server the problem is that I wanted to add some commands to open guis. As I know, velocity doesn’t support guis, so I registered these guis on my spigot server

and I wanted to forward the command from velocity to my spigot server in order to open the gui

[fossil sundial]

yea, unless a command with the same name exists registered on velocity or a plugin on velocity is blocking it then it should just work

[jolly sandal]

/guild is registered on velocity and I created /guildgui on my spigot server but is there a way to like when someone use /guild gui it forwards it to my spigot server to open the gui?

[fossil sundial]

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/command/CommandExecuteEvent.html
the full command (without /) can be gotten using getCommand()
you can forward it by: CommandExecuteEvent#setResult(CommandExecuteEvent.CommandResult.forwardToServer())

[jolly sandal]

I love you man

really

[fossil sundial]

I’d do something like getCommand().toLowerCase().startsWith(“guild gui”) ….

[jolly sandal]

thank you so much

[fossil sundial]

no problem

[jolly sandal]

pray for australia 🇦🇺

[oblique haven]

Seems like there could be a way to force a chat message or a command for a specific user and just throw the command downstream - without the event

[craggy pecan]

A better way if your commands use Brigadier is to return https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/command/BrigadierCommand.html#FORWARD from your executable nodes

There is no clean way to do this with InvocableCommands

[fossil sundial]

I agree; however I assumed since it was a subcommand that it has to be registered; and that wouldn’t be the case if it were a Brigadier command

[soft slate]

Is there an event that is invoked if a connected server comes online/shutdsdown?

[zealous epoch]

public static LiteralCommandNode<CommandSource> rootCommand() {
        return LiteralArgumentBuilder
                .<CommandSource>literal("vss")
                .executes(context -> {
                    //
                    Component message = Component.text("§4Too few arguments! §e/vss help§4 for help");
                    context.getSource().sendMessage(message);
                    return 1; // indicates success
                    //
                }).build();
    }

how can add suggestions for my Child commands?

I get this but I have 2 commands [ start, help]

and when I input anything I get this:

[opaque escarp]

Please do not use legacy color codes with components, it is the worst combination. If you want to use that kind of deprecated characters, use the LegacyComponentSerializer#legacySection

[zealous epoch]

it was only for testing 🙂

first time coding with brigadier so yea I have nothing I can work on

[queen pasture]

how do i make a command in evelocity

?

the doc seems outdated

this dont work

the interface is empty

[queen pasture]

nvr mind found it

its SimpleCommand

[rigid vine]

Is there a tutorial for SimpleCommand, which shows me how I can suggest a list for argument 0, if I enter something or leave it blank and then for argument 1?

And please don't direct me to the docs.

[robust mural]

You can look at this: https://github.com/PaperMC/Velocity/blob/dev/3.0.0/proxy/src/main/java/com/velocitypowered/proxy/command/builtin/VelocityCommand.java#L127

[craggy pecan]

You add SuggestionProviders to the corresponding nodes (the RequiredArgumentNodes)

[rigid vine]

Thank you very much.

[wary tiger]

You're looking at the wrong documentation then. See https://velocitypowered.com/wiki/developers/command-api/

[mild crest]

Can you add a link to those docs to the channel topic or pin that message?

[wary tiger]

I'm not an administrator but someone who is can

[opaque escarp]

https://gist.github.com/4drian3d/8b8db7bd01d2c7b4f8a7e4744620afbc

It's not perfect, I need to explain better the RequiredArgumentBuilder, but I think it works

[vernal compass]

If any, it should link to the new docs under the papermc domain. https://docs.papermc.io/velocity/developers/command-api

[thick bramble]

its not marked as such but that's still a bit todo. the velocity docs are a mess right now

but as its been public on the site for a while/not marked as that i'll add redirects for anything changed

[craggy pecan]

Really nicely explained

[opaque escarp]

I have sent a pull request summarizing a little of this tutorial and improving the documentation of the commands https://github.com/PaperMC/docs/pull/46

[royal pulsar]

Is there any way to send additional information to a server that you're forwarding a player to while you're forwarding that player? Things like a location to move them to?

(or really just any arbitrary data)

[molten ember]

If you're intending to make calls to a paperMC server without any players connected, your only options are to either use websockets, or some database like system (like redis with pub/sub).

I'm not too sure as I was trying to do something similar, but it seems that plugin messages require a player to be connected to the server you're sending them to.

[royal pulsar]

Yeah, I guess I'll just send something to the target server ahead of time out of band

Was hoping there was an in-band way with login requests or something

But whatever works lol

[opaque escarp]

Is there a stable alternative to "https://jd.velocitypowered.com/" ? 2 months ago it was announced that it would stop working in ||3 days|| but so far there is no replacement as far as I can see

[rich hawk]

that one is updated

[opaque escarp]

Important service announcement:

jd.velocitypowered.com, ci.velocitypowered.com, and friends will be turned off on March 7th, 2022. I will ensure historical Velocity downloads will be archived and remain accessible.

in velocity discord

[rich hawk]

oh idk

[opaque escarp]

wait...

"March" 🤔

So... will it still be available or will it move with the other PaperMC javadocs on https://papermc.io/javadocs ?

[rich hawk]

probably get moved? since everything else is getting moved

[royal pulsar]

When things go get moved, will there be a single source of truth for docs? Right now I get most Google results going to the ReadTheDocs-style site instead of the wiki where current docs seem to be

[fleet sail]

https://docs.papermc.io/velocity/migration#migrating-from-velocity-10x-to-velocity-110

[nova sparrow]

Making a plugin with a gui, however all my item lore and names are italic

setItem(49, new ItemBuilder(ItemType.EMERALD).name(VelocityChat.color("&a&lCreate new")).lore(VelocityChat.color("&7Click to create a new announcement")).build());

[bold wharf]

Disable the italic on the root component

[oblique haven]

this is gui stuff in velocity - I don't think it's supported at all

but yeah - you need to explicitly disable it, if that doesn't work then

[nova sparrow]

Cheers you two, ill try that

[thick bramble]

At some point, yes. Although papers jd stuff will be changed as well in the future. For the moment jd.velocitypowered.com is your best bet

[oblique haven]

#paper-dev message source

[nova sparrow]

Worked! Thanks

[covert folio]

Does velocity have some documentation on it's internal structure? Been reading through it's network code for a while and some things there are kinda confusing

[maiden hawk]

Wait, GUI's are supported in Velocity?

[bold wharf]

no

[maiden hawk]

Unfortunately, Velocity implementation is mostly undocumented.

[bold wharf]

GUIs are not supported but, I mean, it's just packets

[maiden hawk]

I know that there exists some Library for it

[nova sparrow]

No

[covert folio]

😦

[rigid vine]

RegisteredServer rs = proxyServer.getServer("servername");
boolean rsState = rs.isPresent();

rsState should be true, if the server is online, right?

[robust mural]

No

[rigid vine]

no?

okay

then I don't have any ideas, how I can check, if a server is online 🤣

can someone tell me, how I can ping the server to check, if it's online?

I don't get it to work

[bold wharf]

have you looked at the javadocs?

Generally the only way to know it's online is to ping it or have some external system which tracks that

[rigid vine]

That could be a problem. I needed over 3 months to understand the discord.js docs. JavaDocs are a little bit harder 😅

the ping method is not the latency, right?

[bold wharf]

no

it actually pings the server and returns a response, as per the javadocs

[rigid vine]

where can I find it in the javadocs?

I searched with the word ping

[bold wharf]

https://jd.velocitypowered.com

[rigid vine]

Already there https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/server/ServerPing.html

[rich hawk]

wrong ping

[rigid vine]

okay

I don't get it

I'm too stupid for this

||And I'm going to sleep now.||

[rich hawk]

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/server/RegisteredServer.html#ping()

[rigid vine]

So I have to do

CompletableFuture<ServerPing> result = registeredServer.get().ping();```?

[fossil sundial]

you‘re motivated to add a complete listener to that. If thats not an option force it to wait with .complete() but be sure to catch any exceptions that might be thrown

[rigid vine]

where do I need to add the .complete() ?

[fossil sundial]

the .ping() gives you a future that will be completed at some point. if you want to wait for it to complete then do .complete() to wait for the future

this may thrown an exception if the server is down or some other interruption occurs

[rigid vine]

That's the reason I want to ping the server ^^"

I want to check, if it's online or offline

Do I have to do it like this?

Btw. I saw, what you wrote here, Five 😅

[fossil sundial]

sec

[rigid vine]

KK

😅

[fossil sundial]

@Inject
private ProxyServer proxyServer;

public boolean testIsOnline(String serverName){
    Optional<RegisteredServer> toTest = proxyServer.getServer(serverName);
    if (toTest.isPresent()){
        RegisteredServer server = toTest.get();
        try{
            ServerPing response = server.ping().get();
            return true;
        } catch (Exception err){
            // Ideally check for IO error or interrupt here
        }
    }
    return false;
}

something like that

[rigid vine]

I get an error, when I insert that into the code

[fossil sundial]

my bad; it was .get() remembered wrong

[ruby spear]

https://github.com/PaperMC/Velocity/issues/633

is this intentional

[rigid vine]

Thank you ^^

[cerulean charm]

Hi, where can I change this text?

[burnt dragon]

you can't - velocity does not support removing attribution

[cerulean charm]

I just have a few proxies and I need to know which one the player is on

I was thinking of writing a number there

[waxen mirage]

Hello, is there any way to execute the command via console on velocity? Like dispatchCommand on bukkit

[opaque escarp]

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/command/CommandManager.html#executeAsync(com.velocitypowered.api.command.CommandSource,java.lang.String)

[waxen mirage]

thanks a lot bro!

[merry seal]

is there a way to get players ip via PostLoginEvent?

[fossil sundial]

haven’t looked at it. Will on the weekend

[fossil sundial]

PostLoginEvent#getPlayer().getRemoteAddress() returns an InetSocketAddress from the player

[merry seal]

thanks

[royal pulsar]

That text is set by the minecraft:brand plugin channel

https://wiki.vg/Plugin_channels#minecraft:brand

The payload is a single UTF-8 string

[cerulean charm]

Thanks

[royal pulsar]

It looks like Velocity adds its own info though by MITM'ing the packet: https://github.com/PaperMC/Velocity/blob/2586210ca67f2510eb4f91bf7567643f8a26ee7b/proxy/src/main/java/com/velocitypowered/proxy/protocol/util/PluginMessageUtil.java#L123-L140

I think just adding the word "Velocity" to it

[cerulean charm]

Yes, I have already found this class

Now I'm trying to output this value to the config for convenience

[nova knot]

ive got a very simple problem and its kinda awkward that i have to ask that but i never worked with path objects and i want to create a config file for my plugin so..
how do i create my plugins directory using this datadirectory path?

[nova knot]

nvm got it

[zealous epoch]

Thank you for the nice explanation! It did really help me understand how brigadier works.
But it is really a mess for reading bcs everything is connected in 1 node from the start.
How can you split them?

[opaque escarp]

you could split it into several CommandNode and concatenate one with the other by using an addChild... but personally, I totally prefer the way I explained it

[zealous epoch]

Ok thank you!

[zealous epoch]

how does velocity handle configs?
How to get/set/save them?
someone has an example code?

[bold wharf]

basically, it doesn't

it does bundle configurate, however

[zealous epoch]

cant find any docs do you have a link=

?

[bronze yoke]

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

[robust mural]

The wiki is for v4 in Velocity is v3

[zealous epoch]

Do you have any example plugin I could look into?

[opaque escarp]

In the same repository there are examples of its v3 https://github.com/SpongePowered/Configurate/tree/3.x/configurate-examples

[zealous epoch]

Can I text you in direct messages? I really dont get it.

[opaque escarp]

I have no idea how to use Configurate 3, I tried to use it, but it never worked xd In my plugins I use Configurate 4 or Toml4j

[zealous epoch]

Ok then could you help me to get configurate 4 working?

[opaque escarp]

To use Configurate 4 you must shade and relocate Configurate, from there, the Configurate wiki explains its use well https://github.com/SpongePowered/Configurate/wiki

[burnt dragon]

sponge also has a discord

[winged pike]

what

[bold wharf]

did you shade configurate 4?

cos, I mean, whatever you're doing, you have a version mismatch

[winged pike]

Configurate?

im using simple yaml

yes, i'm shading both snakeyaml and simple yaml i've tried it doesn't work idk it can't find a method

[oblique haven]

are you sure it's getting shaded

check the contents of the uber

[thick bramble]

You need to relocate snakeyaml if you're using a different version

As velocity already includes it

[winged pike]

ye

[winged pike]

it doesn- which version of velocity are talkin about

im using 3.1.2-SNAPSHOT

[thick bramble]

Let me double check. I'm not very familiar with velocity at all but I swear it does

Not simple yaml, snakeyaml

[winged pike]

mh

[thick bramble]

Simpleyaml depends on snakeyaml and it looks like you've got a version mismatch

So you need to shade and relocate a matching version

Or downgrade/upgrade simpleyaml to match the version of snakeyaml in velocity

[winged pike]

ye

apparently is 1.26

btw what you mean by relocating a matching version, like i know how to relocate by i mean wdym by matching version

[thick bramble]

Ignore that part. It'd be a transitive dependency of simpleyaml so you don't need to care. What I meant was ensure your jar ships the version simpleyaml is expecting

[winged pike]

i mean i need some features of simpleyaml

i tried using the 1.7.2 which uses snakeyaml 1.26 but it doesn't contain some stuff that i need

so its best relocating

[rich hawk]

and shading

[winged pike]

I shaded already

I think I just need to relocate

[ashen fiber]

Piracy is not supported.

Go ask for help in /dev/null.

[elfin snow]

For some reason I can't run velocity plugins built with gradle if they have redis, I get the following error on startup and don't understand it
This line seems to cause it

implementation("redis.clients:jedis:4.2.1")

I'm guessing it's something to do with the slf4j shading but I can't seem to fix it

lol, found it finally, I was excluding the thing wrong, solution is to change the dependency to this

implementation("redis.clients:jedis:4.1.0") {
    exclude("org.slf4j")
}

[fossil sundial]

I’m really sorry; this is a remnant from the log4j bug; there’s a filter in some versions of velocity that collides with that namespace
I’ll put that on my list of things to address if not already taken care of

[elfin snow]

Yeah saw some old bug related to it but figured it was on my side, thanks!

[gaunt hinge]

So I am using protocolize, and its fine the only problem is that I do not know how packet classes are called

(for ex Bungee has a packet class named Chat, what would the equivalent be? Note: not doing stuff with chat just wanna know if there is a list of packets for velocity)

[oblique haven]

You can look in the Registry

I think it's like StateRegistry or something

[gaunt hinge]

don't see it

[nova sparrow]

i need to figure this out too

was planning on making a scoreboard api/plugin

[rich hawk]

velocity doesn’t have a scoreboard api yet iirc

[nova sparrow]

protocolize is able to send scoreboard packets

id just have to make like

everything myself

[winged pike]

is there a way i can change the max player count?

[fleet sail]

https://docs.papermc.io/velocity/configuration#root-section

[thick bramble]

show-max-players

[winged pike]

i mean like in plugin

coding

[thick bramble]

Oh, missed the channel

The proxy ping event. You can set any custom response

[winged pike]

cool

[river shoal]

hi, is there a way I can make a spigot plugin that connects with velocity?

so like, from the spigot plugin i should be able to get the server id

and also redirect players to other servers

[winged pike]

channels

[river shoal]

can I get the server ID from channels?

[merry trellis]

Would anyone have an advice on how to open a book with Velocity? I am using Protoclize but believe I need a custom packet. Not sure if anyones done this before?
https://github.com/james090500/VelocityBook/blob/master/src/main/java/com/james090500/VelocityBook/helpers/BookLauncher.java#L47-L69

[bold wharf]

it uses the custom payload packet last I knew

[merry trellis]

I'm fairly new at custom packets. Are they accessible through the API or is there a guide I can read up on?

[bold wharf]

it's not a custom packet

it's literally part of the mojang protocol

Oh, wait, it's now its very own packet

[nova sparrow]

need to know this (or something along the lines of this) too

[fossil sundial]

I plan on maybe rolling out support for book Interfaces alongside plugin intents
My opinion is that proxy doesn’t have to load or keep features open that aren’t being used and specially these tend to create strain even if not required

But scoreboards are still the first ones with that limitations

[pallid otter]

@nova sparrow @merry trellis https://github.com/bolt-rip/nerve/blob/master/src/main/java/rip/bolt/nerve/protocol/RegisterPackets.java#L32

your pom.xml will need the velocity-proxy (I use system scope & a local file)

    public void playDing(float volume, float pitch) {
        player.getConnection().write(new DingSoundEffectPacket(position.x, position.y, position.z, volume, pitch));
    }

[merry trellis]

Thank you for the help

[merry trellis]

Say I want to convert a legacy string to json is the best way really

Component component = LegacyComponentSerializer.legacyAmpersand().deserialize("&6Hello &b&lworld&c!");
String json = GsonComponentSerializer.gson().serialize(component );

Just feels a bit to component from component situation

[burnt dragon]

yes that basically is the best way

the component structure is the middle ground, you need to go from legacy -> component if you've got any hope of getting it back out again into json

[merry trellis]

Ah that's fine by me. I just didn't want to be doing it a wasteful way!

[merry trellis]

Ok, hopefully my final question. I've made a plugin on Velocity which puts a fake written book into a players inventory, opens it and removes the book. Basically to create a pop up notification.

Obviously, the problem is that velocity has no way of knowing what original items was in the players inventory, so at the moments it replaced with air.. not helpful!

I assume.. I'd need to send a packet to the paper server to say initiate an inventory update, basically to resend the players inventory back to them... is this possible? Or am I look at this the wrong way

I assume, I somehow need to get the server to send this... https://wiki.vg/Protocol#Window_Items

[bronze yoke]

I don't remember having to put a book into a player's inventory to open a book?

[burnt dragon]

you do now at least, give them the book and then tell them to open what's in their hand basically

[bronze yoke]

ah okay

[jolly sandal]

Hi do you guys know why PlayerAvailableCommandsEvent is marked at Beta is there still some bugs? And will the next version fix the problem?

and could you give me an example of how use it?

to remove some available commands from the list

[craggy pecan]

Iirc it was marked @Beta due to the integration with Brigadier, I think it's safe to use by now. You get the root node and modify it as you please (see Mojang's docs for more details)

[rigid vine]

How are you guys writing the velocity.toml ? I want to make a config file for my plugin, but I don't know, how I can write my config like you wrote yours 😅

[uneven trench]

is there a way to communicate from server to velocity without a player present on the server? the simplest way I can think of to do that is just add a plugin to velocity with a custom server running to listen for requests but is there a more idiomatic way to do it?

[oblique haven]

I don’t believe so

You’d need to have a plug-in or something

[rigid vine]

I'm not sure, but maybe this helps https://github.com/PaperMC/Velocity/issues/68

if that's the way to communicate, that you mean

[bold wharf]

no

[uneven trench]

no that's an api that allows you to send messages to velocity via a person connected to the server, I'm looking for a means of connecting without anyone on the server

[ashen pawn]

Lots of options out there, take your pick. Redis PubSub, RabbitMQ, PostgreSQL LISTEN/NOTIFY, ... - the list of ways to talk to two different processes are numerous, you don't need a proxy for that

[uneven trench]

yeah I'm aware of ways to communicate between servers not using a proxy, just didnt know if there was a way built into velocity

we're using redis

[ashen pawn]

tl;dr: the answer is no, other solutions do a fine job of providing this

[uneven trench]

cool cool

[maiden hawk]

I personally recommend RabbitMQ, it offers way more options than those other

[gray hedge]

Is there way to hold an event till a completable future joins? for LoginEvent

Or do I just block the thread

[bold wharf]

think that events had a continuation thing?

[gray hedge]

Oh yea found that

[jolly sandal]

Hi guys do you know if there is an event PlayerChangeServerEvent or a way to get when a player change server

[rigid vine]

Is there a way to use something like ChatColor.translateAlternateColorCodes in velocity?

[bold wharf]

I mean, ideally, don't use legacy text.

otherwise, if you must, use the legacy serialiser

[rigid vine]

this? https://docs.adventure.kyori.net/serializer/legacy.html

[bold wharf]

yes

[boreal shore]

Can I create fakeplayers global tablist using velocity api, or should I create global tab using that api, and add fakeplayers using e.g paper api

[agile ore]

how can I get a ip address

like I know InboundConnection#getRemoteAddress

but the problem is how do i continue to get a plain xyz.abc.def.ghi version

[fossil sundial]

// InboundConnection as conn
Optional<InetSocketAddress> host = conn.getVirtualHost();
if (host.isPresent()) {
    String hostName = host.get().getHostName();
}

the inetsocketaddr is an unresolved object in this case so getHostName is the correct way to go

and its optional because the client may omit (empty) the field in any type of situation. Protocol doesnt require it to be filled

[boreal shore]

^

[bold wharf]

no

[fossil sundial]

Not sure what you’re trying to do

[bold wharf]

the API does not cover sending that stuff

ofc, you can do it, it's just not something that the API supports afaik

[agile parrot]

Can a velocity permissions plugin's permissions (such as luckperms) be read by player.getEffectivePermissions() in paper?

[fossil sundial]

No. You can only ask the provider for certain permissions but not get a list because depending on context it may be different

[bold wharf]

they're two entirely different processes with two entirely seperate chunks of RAM, state, etc, etc

the only way to get that info between the two of them would be if you had a plugin to send that info over, or if your perm plugin lets you get that another way

ofc, LP won't expose "effective perms" for the proxy in the server if they don't apply, which, depends on how you setup perms

[fossil sundial]

LP is also no stranger to conditional permissions so an „effective“ permission is effectively worthless

[agile parrot]

Is there any news on velocity getting scoreboard api?

[fossil sundial]

There is but it’s a bit more complicated
Scoreboard will be the first api part to be a privileged api component
And the framework for that is nearly done
Ideally velocity should only inject in scoreboard communication if a plugin requires it and by requiring plugins to declare intentions so the feature can be deactivated while it’s unused will save CPU and resources

Ideally by the next release everything except commands will require declaration
For now this is going to be the first step

[boreal shore]

should I use gradle kotlin build script for velocity or not? (iirc for paperweight userdev I used gradle kts)

[bold wharf]

I mean, use whatever build script format you want

just note that kts tends to be more supported in these parts

[agile parrot]

Privileged?

[fossil sundial]

That’s just a fancy way of saying you need to tell the proxy that you need it.

[agile ore]

@fossil sundial thanks

[boreal shore]

what will it look like for kts? I'm not good at it, I haven't had much contact with gradle

[nova knot]

is there a way to display ä,ö and ü properly in a textcomponent?

[bold wharf]

works just fine

check your encodings

[nova knot]

i just use utf8?

or can i change it in a config?

[bold wharf]

You use utf8

make sure that your compiler is configured to use utf8 and that your source files are in utf8

[nova knot]

alright

[boreal shore]

^

[bold wharf]

Take a look at other projects using kts, etc

[boreal shore]

umm, any examples?

[bold wharf]

no

[opaque escarp]

Is there any possibility to publish the current progress in a separate branch for experimentation and feedback?

[boreal shore]

should it be enough?

[thick bramble]

add annotationProcessor("com.velocitypowered:velocity-api:3.1.1") under dependencies as well

otherwise looks fine. you can also replace the velocity repo with the paper repo as the velocity one is deprecated, https://papermc.io/repo/repository/maven-public/

[boreal shore]

with old repo i cant use 3.1.2 version, with actual repo it should works?

[bold wharf]

3.1.2 is a snapshot still

[oblique haven]

Awe you decided to not make brigadier an intent?

[fossil sundial]

[boreal shore]

what are differences between that?

[rich hawk]

one is asynchronous one is not

[gray glacier]

hey, im trying to build the proxy module, but it is not showing up in my maven repository, is there something special i need to do? api and native show up in my repository

i did build it the way the readme tells you

[fossil sundial]

The proxy part is not api. It will not show up in maven because it’s not designed to.

[gray glacier]

yeah i realize that now

is there a way to get my plugin instance?

would i just implement the plugin or plugincontainer class?

[oblique bay]

I think you could do server.getPluginManager().getPlugin("plugin_id"); if I'm not crazy to get the container and then the instance

[gray glacier]

this is kind of confusing, is my main class my plugin instance?

[oblique bay]

The one you use the @ Plugin annotation on is (sorry random person named sub, I'm dumb)

It's the entry point

[gray glacier]

okay

is there something i can implement/extend?

cuz i have a non-platform specific command api and the way it works is checking instance of proxyplugin, javaplugin, etc

so i need an equivalent for velocity

[oblique haven]

there is no equivalent, you'd need to make it up

[gray glacier]

well originally i was registering commands using the proxyserver instance which i have no issue retrieving

but i dont know if thats proper

as in spigot and bungee you register commands through the plugin interface

[oblique haven]

well you're supposed to use the proxyserver's command manager

[gray glacier]

ah okay i guess that makes sense

[oblique haven]

    private void setupCommands() {
        CommandManager commandManager = this.server.getCommandManager();
        for (String command : new String[]{"glist", "server", "shutdown", "velocity"}) {
            commandManager.unregister(command);
        }
    ...``` as such

the command manager is a global thing

commands aren't tied to plugins

[jolly sandal]

Hi, is there a Component that allows backline? One that basically does \n

[burnt dragon]

Component.newline()?

[jolly sandal]

Thanks bro

You dont know how much time i searched

to find this

[burnt dragon]

you can also just use a newline character in most cases

[jolly sandal]

and you know why colors with § dont work when going to a newline

[burnt dragon]

becuase legacy section sign colouring is not supported at all inside components

don't use them

[jolly sandal]

okay

because Ive created a system to send messages to players between my velocity instances

but I cant really send any other color sign that §

So ig imma create a parser for this

[burnt dragon]

yes you can - you can use the format minecraft uses to transfer components over the wire

adventure's gson serializer handles this

or, if you wanted to use the legacy format for whatever reason, you can just use the legacy component serializer

[jolly sandal]

im not using json, im using bytes lol thats why

[burnt dragon]

what

you can put anything in bytes

[jolly sandal]

with rabbitmq

but wont

that be weird?

[burnt dragon]

what do you think bytes are?

[jolly sandal]

010101

8 bit

[burnt dragon]

yes, and that's everything

[jolly sandal]

ik

[burnt dragon]

these messages are bytes

[jolly sandal]

yh

[burnt dragon]

so ofc you can turn a json string into bytes

[jolly sandal]

thats why I actually do

but the thing

is that I prefer not using json bc of performances

Do you know Charal?

[burnt dragon]

have you genuinely noticed a performance issue

or are you just preemptively optimising for no reason

[jolly sandal]

its a big company that made an minecraft event recently. It uses something that sent a lot of packets

and the developer used json but that was pretty risked and finally their server crashed

[burnt dragon]

there is no way that transferring json caused a crash lmao

[jolly sandal]

no I just dont want to change my system after

[burnt dragon]

look, minecraft uses json in every component related packet

[jolly sandal]

it did, like they created a system that showed all the players around x blocks on all servers even if we werent in the same server

[jolly sandal]

ikt

[burnt dragon]

what has that got to do with json?

[jolly sandal]

and thats why a simple game consumes a lo

bc to send the packets with rabbitmq to others servers

they used json

and it took so many time

I really dont want to change my system after bc it will be a lost of time

[burnt dragon]

i mean that sounds completely unrelated to sending json encoded chat packets between servers

[jolly sandal]

bc it sends a lot of messages

[burnt dragon]

chat messages are going to be infinitely less intensive than players

don't waste time, use json and just change it later if you notice an issue (you wont)

[boreal shore]

How can I connect a player to the server and automatically set his location? For example, if the player uses /test, he will teleport him to the given server and coordinates 0 0, but if he reconnect, it is in the place where he was

[half vine]

you need a plugin on the server and the proxy for that.
the proxy can send the extra tp request to the server via plugin messaging

[boreal shore]

Oh, ok, thx!

And one more question. Can I somehow send console message to the plsyer's current server?

[half vine]

plugin on the server and proxy and send a plugin message

[fossil sundial]

This would be the perfect case where the login plugin messaging api velcoriy provides would be useful; sadly however paper doesn’t support it as api yet

[bold wharf]

it's kinda been on my todo list but I didn't figure out the best way to really expose it nicely given the existing API

[fossil sundial]

I’m all for doing it like it’s done on velocity- with a callback

[tawdry sky]

How to show title using velocity?

[opaque escarp]

https://jd.adventure.kyori.net/api/4.10.1/net/kyori/adventure/audience/Audience.html#showTitle(net.kyori.adventure.title.Title)

[tawdry sky]

Thank you

also another question, why does the /server command not work

?

[robust mural]

I think you dont have the permission

[woeful granite]

Hey all, I’ve been developing a velocity plugin and would like to get some basic communication back and forth between the velocity plugin and the bukkit/spigot plugin (in production there are 6 servers in the network). I’ve been reading all the docs I can find.
To communicate between plug-ins on the various servers in the velocity network (including the velocity server itself). Can I just create a custom PluginChannel, register it on both servers and send information that way? Does this require a player to be online or is it possible to send the message as the server? I figure if this is possible I would just setup an event listener when the servers receive messages on that channel.
Am I understanding this right?

[wild quest]

@woeful granite I wrote some code that uses PluginChannel a little while ago and I think you're on the right track. If u want I can send you some code later but I'm about to sleep rn 😛

[woeful granite]

Honestly that would be super helpful. I’ve been looking at some existing plugins but I think it will be much easier to understand what’s going on with a simpler implementation. Thank you, and no rush at all.

[bold wharf]

Yes, you''d just register the channel on the proxy and it'll let you send stuff back over

it needs a player online as it just hijacks the players connection for it

if you require reliable/without a player, you'd be better off using some form of message broker

[final lynx]

e.setResult(PreLoginEvent.PreLoginComponentResult.denied(create(configuration.getNode(webMsg).getString())));

I'm just stuck in "Connecting" until it timed out on the client

not sure if this is a bug or am I doing something wrong?

[ruby spear]

@fossil sundial did you look into that issue I talked about over the weekend btw? https://github.com/PaperMC/Velocity/issues/633

[wild quest]

@woeful granite I guess I was mistaken. I remembered looking into cross-server messaging with velocity but that notion I think was misguided. You might look into using something else in addition to velocity. So yeah pretty much what electroniccat said.

Redis is a popular solution I believe.

[tawdry sky]

Nope

The command straight up doesn't exist

All other default commands do

[tawdry sky]

also should mention that it responds in the console, just not for my player (or other people)

latest snapshot

[robust mural]

If you don't have permission, it doesn't exist for you

[opaque escarp]

In Velocity, if a user (or the console) does not have permission to execute a command, the command will be hidden and when the command is executed, it will be sent to the server where the user is connected (in case the executor is a player) ||and to think that in bungeecord it shows you an error message, how antiquated||

[tawdry sky]

I have the * permission in LPV

[opaque escarp]

then use /lpv verbose command (username or "me") "command" https://luckperms.net/wiki/Verbose

[exotic frigate]

Hello! How can I dispatch command with velocity API, when I'm using spigot API, it's method Bukkit.dispatchCommand(consoleSender, command). Is it possible to do that with velocity?

[fossil sundial]

proxyServer.getCommandManager().executeAsync(CommandSource sender, String command)

Command source is either a player or the proxy with proxyServer.getConsoleCommandSource()

[exotic frigate]

thank you!

[fossil sundial]

Side-note if you don’t want this to fire a CommandExecuteEvent you could also use .executeImmediatelyAsync(…)

[exotic frigate]

okey, thanks for note about it

[south garnet]

hey, i've got a problem with my velocity proxy or with a the plugin api. i wanted to code a warp all players to a server but proxy.getServer(...) returns an optional datatype. this is why i cant warp any players to a different server because it wont accept a optional data type
any ideas?

[burnt dragon]

unwrap the optional - plenty of guides online

https://www.baeldung.com/java-optional

[south garnet]

thx ❤️

i forgot

[south garnet]

how can i send players to a different server with my plugin

?

[boreal shore]

Can I get luckperms prefixes / sufixes from database or should I do it with their api?

[bold wharf]

you should do it with their API

[sacred musk]

Is there a way to move player from one server to another using API without firing ServerPreConnectEvent?

[oblique haven]

Not really - what are you trying to achieve

[south garnet]

player#createConnectionRequest does not work but without any exception throwing

did anybody got an idea

[sour current]

you have to use .connect or .fireAndForget, see https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/ConnectionRequestBuilder.html

[ebon cradle]

[ebon cradle]

Thank you 🙂

[plain ledge]

hey, does anyone know what's going on here?

[boreal shore]

Doing fakeplayers tablist using velocity api is a good idea or doing it with paper api is better way?

[fossil sundial]

Paper, purely based on the fact that the api is very limited on velocity

[boreal shore]

Ok, and what about global chat and direct messages between the servers? Better way is doing it with paper or velocity is ok for it?

[ashen pawn]

You are trying to initialize your plugin in the constructor. Don't do that. Listen to ProxyInitializeEvent. The init block is the Java class constructor.

[inner willow]

In relation to this, when is tab/scoreboard api releasing?

[plain ledge]

Oh yes, thanks

[fossil sundial]

I said this once and I’m going to say it again, I don’t do ETAs. I’m welcoming to outside contributions though since I seriously don’t have the time currently

[exotic frigate]

hello, I have problem with executing command in velocity api

server.getCommandManager().executeImmediatelyAsync(server.getConsoleCommandSource(), "/adminchat example");

/adminchat is command from my other velocity plugin

It doesn't work, also in console there aren't any errors

[bold wharf]

I guess, remove the /

[exotic frigate]

I will try

doesn't work

[bold wharf]

define "doesn't work"

tried using a debugger and stepping through it?

is the command registered properly in the proxy?

etc

[exotic frigate]

it doens't execute command

[exotic frigate]

yea, I can use this command in minecraft

this is my code, message is sending, but command doesn't execute

[craggy pecan]

What does the command do? Do you see any output/errors in the console?

You're executing the command for the console, not the player

So the player will get no feedback about the command execution

[exotic frigate]

it send message to all players with permission

[craggy pecan]

Can we see the command implementation?

[bold wharf]

first thing I see is a blind cast

[exotic frigate]

where?

[bold wharf]

literal first line of your execute methods

[exotic frigate]

it is nessesery

[bold wharf]

You're running the command as the console

the console is not a Player

[exotic frigate]

oo

[fossil sundial]

Audience is the superclass to send messages

Both also inherit PermissionSubject

[fossil sundial]

So Audience sender = (Audience) invocation.source();

[elfin gorge]

Hello.

port = ((VelocityConfiguration) server.getConfiguration()).getBind().getPort();

I have this thing in my velocity plugin
using maven to compile, error:

pom xml here

[fleet sail]

pom.xml by @elfin gorge: https://paste.gg/a26c4e396a5d4749bcf651b6942aaae6

[fossil sundial]

Your JDK is mismatched

Also are you trying to create a plugin here?

[elfin gorge]

port = ((VelocityConfiguration) server.getConfiguration()).getBind().getPort();

If I remove this line, the plugin can successfully made.

[elfin gorge]

yes it's a plugin

[fossil sundial]

Yes and this makes sense
You also don’t need to use proxy internals to get the proxy port

There’s the ListenerBoundEvent

You can get the port form that

[elfin gorge]

this line is triggered when the plugin enabling
I just want to store the port in somewhere
so.. I think I don't need to use event?

[fossil sundial]

The config isn’t exposed for the reason that the data there may not be accurate. What you’re reading in the config maybe transformed by the system so the port or address may not match
This is the sole reason it isn’t exposed
But to get rid of that error you need to compile against the same java JDK version as velocity

[elfin gorge]

I changed the jdk to 11
but there's still some error
git bash: mvn clean install

instead, I can build using this clean install in the intellij

[fossil sundial]

Velocity builds against JDK 17

[elfin gorge]

alright, it's working

[elfin gorge]

oh ?

i thought it's 11

[fossil sundial]

3.1.2 does

3.1.0 and earlier did 11

You should upstream update your fork

[elfin gorge]

I'm using 3.1.1 velocity build 98

so.. should I build the plugin with java 17
it should be better... ?

----------Another question--------
In waterfall, I can set the player's uuid in PreLoginEvent
Is it possible to do it in the velocity ?

[inner willow]

How to check if a server is joinable?

[bold wharf]

Literally all you can do is try

[inner willow]

API wise

Like how do you check if a server is joinable

Whitelist etc

[bold wharf]

You literally can't

Velocity doesn't know if you're whitelisted or not

velocity doesn't know if the server is full or not

Unless you're storing that data somewhere that velocity can access it, the only way to know if X player can actually join a server is to join the server and see if it allows you in or not

[fossil sundial]

I guess? But honestly doesn’t matter a lot for normal plugins

[fossil sundial]

GameProfilRequestEvent

Note for that event: whatever you set will be ignored if you have forwarding disabled (to not break the client)

[boreal shore]

^

[bold wharf]

depends

[fossil sundial]

Works on velocity well enough imo
Unless you need data from the server

[bold wharf]

many people preach for offloading stuff on the proxy, but, bearing in mind that the proxy doesn't have the info that the server does if you're wanting to deal with stuff like prefixes, etc

[fossil sundial]

Well if you run LP globally that isn’t an issue

But I digress

[inner willow]

Would it at least be possible to check if the server is online via ping

If so what method of ServerPing tells if it's online or not

[bold wharf]

yes

[fossil sundial]

You’ll get an exception instead if the server isn’t online

[inner willow]

I can't seem to find a method under ping isOnline or whatever

[fossil sundial]

You won’t get a ping response is what I’m saying

[inner willow]

So a simple if (serverping) {} is fine?

In the thenAccept*

[fossil sundial]

If you want this to run if the ping fails you’ll need something that also accepts an exception as continuity

Or a separate .exceptionally(…

[inner willow]

I had no idea thenAccept did not run if the server was actually offline?

That's even better.

Thanks.

[fossil sundial]

Someone correct me if I’m wrong here but I’m pretty sure that’s how it works with futures

[bold wharf]

Yea, you'd either have an exceptionally or whenComplete, iirc

[fossil sundial]

Ah whenComplete was the one I was thinking of for both thanks cat

[inner willow]

Just to confirm

ifPresent/isPresent is regarding to

[servers]```

Not toml try = ["shard_1", "shard_2", "shard_3", "shard_4", "shard_5", "shard_6", "shard_7", "shard_8"]?

[fossil sundial]

I’m a bit confused to as what you’re asking but I’ll assume you’re asking about proxyServer.getServer(name)

[inner willow]

That's right

[fossil sundial]

The is/if present there is only about whether the proxy has a registered server by that name or not

Nothing else

[inner willow]

How does the proxy register a server?

Via this list?

[servers]
    # Configure your servers here. Each key represents the server's name, and the value
    # represents the IP address of the server to connect to.
    shard_1 = "172.18.0.1:3001"
    shard_2 = "172.18.0.1:3002"
    shard_3 = "172.18.0.1:3003"
    shard_4 = "172.18.0.1:3004"
    shard_5 = "172.18.0.1:3005"
    shard_6 = "172.18.0.1:3006"
    shard_7 = "172.18.0.1:3007"
    shard_8 = "172.18.0.1:3008"```

[fossil sundial]

Either through the config like that or using the api

proxyServer.registerServer(…)

[inner willow]

How do I get this list?

Oh hold on

getAllServers()

Lovely

[fossil sundial]

proxyServer.getAllServers()

Yea

Judging from this you’ll probably also want to check out the ChooseInitialServerEvent and the KickedFromServerEvent.RedirectPlayer

[inner willow]

So a good way to get a list of online servers would be to iterate through .getAllServers(), pinging them all, .thenAccept'ing them into the list

Or there is a better way you'd recommend?

[fossil sundial]

That works but be sure to make that list access thread-safe

[inner willow]

How?

What does this mean, first and foremost

[fossil sundial]

Thread safety in this case is about data integrity.
Make sure you’re not writing to or reading from the same data from more than one angle at the same time or this stuff blows up basically
The SynchronizedSet or one of the dynamically mutable sets from google guava may work for this

You’re concentrating multiple threads/tasks into one end. Chances are you’re doing two things to it at the same time, and to prevent this from blowing up you need to ensure whatever you’re writing to is equipped to handle those scenarios

[inner willow]

Thanks.

Does .getPlayersConnected() update on or after ServerConnectedEvent

[elfin gorge]

thank you.

[crystal heath]

so I'm guessing building on an m1 mac isnt supported right now? My first time cloning the velocity repo and I get a missing dep error when I try to build for netty-transport-native-epoll-4.1.75.Final-linux-x86_64.jar

or am I just totally missing smth

[bold wharf]

I mean, it's just a dep, it should pull it just fine?

[crystal heath]

well idk, it says it only looked for a file in my local m2 repo

actually, pretty sure that file exists

on no, only one of them exists

[bold wharf]

It only looked in maven local doe?

[crystal heath]

apparently, thats what the error says

I literally just cloned, and ran ./gradlew build

[bold wharf]

I mean, it failed to find the native for x86 and aarch from there, so, er

maybe relevant that our repo is shitting the bed, but, surely that woulda shown up in the list as a place it looked? o.O

[crystal heath]

err well I just deleted the 4.1.75.Final folder from my local repo and then it works

so who knows what was happening

[bold wharf]

well, the thing likes to cache where it pulled something from and stick to fetching from there, so, something went sideways

[final lynx]

how do I determine if a player is connecting through a forcedhost?

[worn pond]

hello, does anyone know how can I sync permissions from database to velocity’s permissions ?

I guess it’s related to PermissionsSetupEvent but I don’t know how can I do that

[bold wharf]

that event is where you register your permission provider

the provider can recalculate its perms whenever it wants to, i.e. you can pull them on setting the provider, periodically, etc, velocity doesn't care about that

[jovial timber]

This is likely a noob thing but im getting this error, how do I make intelij shade a velocity plugin (maven)
java.lang.NoClassDefFoundError: org/json/simple/parser/JSONParser

[jovial timber]

I have it added like this

        <dependency>
            <groupId>com.googlecode.json-simple</groupId>

            <version>1.1.1</version>
            <scope>compile</scope>

        </dependency>```

[bold wharf]

you need to make sure that you setup the maven shade plugin

[jovial timber]

is that like an intelij plugin or part of maven

[bold wharf]

it's a maven plugin

[raven rock]

you just add some things to the pom

[jovial timber]

this?

                        </executions>
                    </plugin>```

[bold wharf]

yes

[jovial timber]

then i do package?

[bold wharf]

yes

[jovial timber]

it does not seem to be working

do i have to reload it or something

[bold wharf]

check the build log

[jovial timber]

https://paste.gg/p/anonymous/710777bd0f344e92b19e2b9efb21d0ca

[bold wharf]

shade didn't run

[jovial timber]

do i use this package

[bold wharf]

yes

[jovial timber]

the default scope is what i want right?

[bold wharf]

default scope was compile iirc

[jovial timber]

according to https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html yes

ig my problem is shade not running as u siad

anyone have suggestions

can gradle shade

[simple epoch]

yes

[jovial timber]

is it easy

or like should i just try to get this working

[simple epoch]

i would say, on maven it's easier

[jovial timber]

ok

im using the minecraft dev intelij plugin would that mess with it maybe

[simple epoch]

basically not

[jovial timber]

ok

well

um

does this look right for plugins
https://paste.gg/p/anonymous/5983cc5ac82b4a1a9be998089ca6d492

[nova sparrow]

why would that be wrong

@jovial timber noah look here

https://github.com/Matt-MX/AnnouncerVelocity

if you’re having trouble with maven

[nova sparrow]

also @jovial timber let me join on vpns on your server!

[plain ledge]

How to connect server in 1.18?

[rich hawk]

import it

and register the channel

on both sides

[plain ledge]

ByteArrayDataOutput don’t exist in 1.18.2

This code is paper 1.8

[rich hawk]

should exists

its in guava

[boreal shore]

is it possible to get player gamemode in velocity?

[rich hawk]

with api no

idk about internals

[boreal shore]

Can I somehow sort players on tablist with velocity api or can I somehow create globaltablist with paper api where sorting is easier imo?

(if it is possible to create the global tab with paper)

[oblique haven]

@boreal shore not at the moment

[boreal shore]

so can I somehow sort tab with velocity

[oblique haven]

no, the api doesn't exist yet

[jovial timber]

well you see thats the problem

how do I shade it!

[nova sparrow]

if you’re using that mc plug-in for intellij it does it for u

try updating that plugin @jovial timber

[opaque escarp]

Would it be a good idea to start annotating new methods or classes implemented in the API with the @since annotation? Since Velocity is the only PaperMC project that uses semantic versioning, I think it could be applied

[jovial timber]

i updated it. should it automatically shade the dependancies from pom.xml when i run package

[nova sparrow]

Yeah it should, the auto generated pom works for me

good luck noah!

[jovial timber]

?

[elfin gorge]

How can I set a player's permission ?
I remember there's a ProxiedPlayer#setPermission
in waterfall

but I don't know how do achieve that in velocity

[oblique haven]

check out the event, it's like PermissionsSomethingEvent or something idk

[craggy pecan]

Setup

[oblique haven]

[minor glacier]

Is there a services manager (like in Bukkit) in Velocity?

I just want a simple way to register a service provider and grab it in another plugin

[fossil sundial]

A what now? Sorry you’ll have to explain what you mean

[minor glacier]

Something like this
https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/plugin/ServicesManager.java

[fossil sundial]

There’s no such concept on velocity

[minor glacier]

👍 thanks

[jovial timber]

still attempting to shade

does it put a shaded jar in another directory or something

im trying to use https://code.google.com/archive/p/json-simple/

[jovial timber]

it seems to shade automatically if i make a spigot plugin

but not velocity

nvm got it

[hushed cosmos]

wiki.vg/protocol

[jovial timber]

how do i do run things async in velocity or is it just async in nature

[rich hawk]

scheduler, also there’s no main thread

[jovial timber]

how do i get server

[carmine trout]

the Audience returned by ProxyServer#getConsoleCommandSource seems to drop all messages, is this expected?

[burnt dragon]

i think it's because it's overriding the wrong method here https://github.com/PaperMC/Velocity/blob/acc407a6d5663eaeddf5051dbaaf1f0a30fa77f7/proxy/src/main/java/com/velocitypowered/proxy/console/VelocityConsole.java#L68

(sorry to push you somewhere just to reply there, i got curious :p )

[carmine trout]

oh hi

nice find

[burnt dragon]

easy PR if you want it, just change that to override the right one

[carmine trout]

yeah it needs to override the one with identity, component, messagetype?

I guess a nice opportunity to clone velocity and make a PR

[burnt dragon]

yup i think so!

[carmine trout]

not sure what the difference is between "system" message type and "chat"

seems ok to just ignore

yeah that fixed it

amazing

[burnt dragon]

system is "the system", so the messages are always displayed (can be death messages, etc) and chat is player chat messages (which are ran through the social filter client side, and probably the text filter eventually)

[carmine trout]

yeah so it probably doesn't matter for console messages

funny how velocity uses the legacy component serializer

[burnt dragon]

yeah the tca thingy does legacy to ANSI so there's no real other way to do it

until adventure writes an ansi serialiser :')

[carmine trout]

sounds like hell

it could support RGB colors which would be nice

[burnt dragon]

I think it does already

[carmine trout]

and it would be nice if the named text colors were translated into the proper ansi escape sequences so it worked with light terminal themes

[burnt dragon]

or that might be a paper only addition

[carmine trout]

currently it results in white-on-white text

but very few people use light themes in terminals anyway

[burnt dragon]

you accidentally added a new line in the imports btw :p

[burnt dragon]

i am one of those people

[carmine trout]

intellij defaults I guess

[burnt dragon]

gotta love them

[carmine trout]

only moved from eclipse this year lol

[outer flower]

How does ConnectionRequestBuilder#connect() work? I tried using it, but it didn't do anything. Do I have to disconnect the user from their current server before running this?

[craggy pecan]

You should check the result of the returned CompletableFuture. Alternatively, just call fireAndForget and Velocity will deal with that for you

[outer flower]

Thanks! I’ll try that tomorrow

[latent zodiac]

How does the forced-hosts config option work? I'd like to make a plugin that replicates this.

Where can I find the code that's in charge of that?

For context, I'd like to run different code on the player depending on the subdomain entered. Each subdomain still points to the same subserver tho but just has a diff function

[latent zodiac]

Figured it out. I needed the following code

        String virtualHostStr = event.getConnection().getVirtualHost().map(InetSocketAddress::getHostString)
                .orElse("")
                .toLowerCase(Locale.ROOT);
        System.out.println("connected from the subdomain: " + virtualHostStr);```

[maiden hawk]

Hi, is it possible to write (images) on maps in Velocity?

I guess there's no official api for it, but is there anything unofficial?

[rich hawk]

need to do that on backend

[maiden hawk]

You don't

It's just all packets

I'm just looking whether anyone has experience with it

[vernal compass]

Don't really see the benefit of doing that on the proxy tbh. Imo all content-related things should usually stay on the backend

[maiden hawk]

I need it to show a QR code to the player

[burnt dragon]

probably easier to do it in chat

[vernal compass]

yeah, at least a version 1 QR code should fit nicely in chat.

If really want to do maps, you will need something to convert the image to map data. there are libraries out there for that, but im not sure if any of them would work on velocity. The rest is just three packets, that should be easy, but the map data is a bit complicated

[maiden hawk]

Eeeh, I need QR code of this size. I doubt it would fit in chat

[vernal compass]

does it really need to be that big? thats quite a lot of data

[maiden hawk]

It will be Authenticator QR code

I think it can't get smaller than that

yup

It can't

[vernal compass]

yeah then you will need to figure out the map data stuff.
Or just do it on the backend and put them in a void world or black room or something until they have authenticated, then you can just use the Bukkit API and MapCanvas#drawImage

[maiden hawk]

Do you (at least) have any libraries which do similar map stuff for bungeecord?

I can port it to Velocity easily (I believe)

[vernal compass]

Not aware of any, and a quick search also found nothing.

https://github.com/cerus/maps this is for bukkit, but it is completely packet-based. that might be helpful

[maiden hawk]

Thanks 👍

[latent zodiac]

Is the velocity forums the only place to advertise / publish a velocity plugin?

Is there something like ore on Sponge or Spigots plugin repo?

[vernal compass]

not yet. Hangar will have a place for that when its finished eventually as far as I know

[latent zodiac]

Sounds good, thanks!

I'll probably write something up later today or tomorrow. Need to do like one or two more features before I release

[merry trellis]

Just want to check im understanding this correctly. if i had 100 players on my velocity server and ran this...

AtomicInteger currentPlayers = new AtomicInteger(VelocityMain.getServer().getPlayerCount());
  VelocityMain.getServer().getAllPlayers().forEach(player -> {
    currentPlayers.set(VelocityMain.getServer().getPlayerCount());
    player.disconnect();
    getLogger().info(currentPlayers.get());
});

I am assuming the getLogger().info(currentPlayers.get()); would output from 100 to 0? I unfrotunately dont have a lot of players to test with

My ultimate goal is to kick any "alts" from the server and if the alt leave room allow a player to join...

[rich hawk]

should probably kick first then set or decrement

[craggy pecan]

I don't see the need for that atomic variable, you're already calling getPlayerCount on each disconnect, save that to a variable inside the lambda and then log it

The solution to non-effectively final type usage inside a lambda isn't prefixing everything with "Atomic"

[latent zodiac]

Is there any examples code wise I can look at for storing data?

Specifically, I just want to store a specific hashset

[craggy pecan]

There's multiple approaches, but it's out of scope for Velocity. For example, you could use a database, a text file, etc. depending on its purpose

If the set contains configuration-related data, we recommend Configurate https://github.com/SpongePowered/Configurate Check their wiki for examples

[frosty hemlock]

Hey, where are the Recipes stored in paper/spigot/bukkit? wrong channel

[bold wharf]

1. Wrong channel
2. provide context towards what you're doing

[frosty hemlock]

Oh sorry

[lunar quail]

is there any way to use ${project.version} from pom.xml in @Plugin annotation?

or a corresponding gradle version property, I don't care which build system to use yet as I've just created a project

[bold wharf]

cleanly? no

I know it's doable, 2 second google points towards stuff like the maven templating plugin, I'd imagine gradle has a similar thing, but, it's generally not ideal

[lunar quail]

so if not using that templating thing, I would have to specify version in 2 places, right?

[covert zealot]

Hello
I was trying to make a caching system.
The idea is to cache data about the player on PostLoginEvent then send it to all Paper servers using plugin messaging.
I realised this might not work, then I tried to send it to the server on ServerPostConnectEvent.
It is working but is there any way to send the cached data to all the Paper servers via plugin messaging on PostLoginEvent?
This is what I originally tried.

@Subscribe
public void onPostLoginEvent(PostLoginEvent event) {
    for (RegisteredServer server : proxyServer.getAllServers()) {
        ByteArrayDataOutput out = ByteStreams.newDataOutput();
        ...
        server.sendPluginMessage(CACHE_CHANNEL, out.toByteArray()));
    }
}

[bold wharf]

well, that will send the cached data towards all servers in which there is a player connected in a state where it can send such data

[covert zealot]

When I tried to join and the event fired the sendPluginMessage returned false

Maybe I'm trying it in a wrong way, but I really want to send the data to all the servers even if there is no player on it

[bold wharf]

plugin messaging uses the players connection

if theres no player connected to that server, theres no player to send that data over through

[covert zealot]

Oh

[bold wharf]

if you want reliable message sending you really need to look into stuff like message brokers, etc

[covert zealot]

I might just try to use redis for caching my data, anyway thanks for the explanation.

[maiden hawk]

In Gradle you can use Kyori's blossom

[maiden hawk]

RabbitMQ ❤️

[river wing]

how can i change 'Not authenticated with minecraft.net' message to something else

[uncut storm]

Hello, can i use velocity with paper in 1.8.8 ?

Because velocity is using java 11 and paper java 8

[rich hawk]

install both java versions

[uncut storm]

i did

[rich hawk]

and run each jar with the /path/to/java for it version

[uncut storm]

in command line ?

[rich hawk]

yes

[uncut storm]

ahhh okay thanks you so much !

[boreal shore]

how can I send plugin message from velocity to paper plugin?

i try to send the message when the pluginmessageevent is fired with:

            ByteArrayDataOutput output = ByteStreams.newDataOutput();
            output.writeUTF("Test");
            output.writeUTF("Heyo!");
            event.getTarget().sendPluginMessage(event.getIdentifier(), output.toByteArray());``` but plugin message listener in paper plugin doesn't catch this

[bold wharf]

make sure that you registered the channel

also noting that a player needs to be online on that server in order to be able to be sent a plugin message

[boreal shore]

i registered the channels on velocity and paper, and the player is online

i send test message from paper to velocity, and it works

and i want to send it back to paper, when pluginmessageevent is fired

on paper i registered the channel as outgoing and incoming (with listener)

[nova knot]

why do i get this stack? adventure is built-in isnt it?

[fleet sail]

stack.txt by @nova knot: https://paste.gg/6af726de77cf49dfbd3ae743bc4787f4

[bold wharf]

probably building against outdated API

[nova knot]

i am using velocity 3.1.1 and velocity-api 3.1.0?

[bold wharf]

that looks like old adventure though

[nova knot]

its v4.10.1 tho

[bold wharf]

or maybe not, https://github.com/KyoriPowered/adventure/blob/main/4/api/src/main/java/net/kyori/adventure/builder/AbstractBuilder.java

[nova knot]

so what should i do? i can tell that in the velocity.jar this class does not exist even though i am using v3.1.1-98

i could try using a dev build but i cant think of another fix

[bold wharf]

you should use a dev build

maybe that's it

[nova knot]

ill try it thank you

[bold wharf]

doing a "stable" release is something I've been asking about doing, just, er, brain, ouch, facedesks

[boreal shore]

any ideas?

Ok, fixed! I have to send plugin message with server connection, not ChannelMessageSink (event.getTarget())

but then how can I catch the message sent with event.getTarget().sendPluginMessage(//)?

[fossil sundial]

Both the Player and ServerConnection can be a source and a target
You need to check instanceof on the sender

[boreal shore]

Yes, but I mean how can I catch plugin message on paper, when i do target.sendPluginMessage paper event doesn't fire

[bold wharf]

event only fires if the channel is registered I think

and the player sending the message is actually in the world

[boreal shore]

Paperjava getServer().getMessenger().registerOutgoingPluginChannel(this, "x:essentials"); getServer().getMessenger().registerIncomingPluginChannel(this, "x:essentials", new Test());Velocityjava proxyServer.getChannelRegistrar().register(new LegacyChannelIdentifier("x:essentials"));

[bold wharf]

oh, doesn't care about the channel being registered, just cares about the state and the listener being registere

LegacyChannelIdentifier

that sounds wrong

Legacy is pre 1.13, i.e. not namespaced

[boreal shore]

ok, i changed it to MinecraftChannelIdentifier.create("x", "essentials") and target works good

thx!

[buoyant kayak]

is ProxyPingEvent async?

[fossil sundial]

Yes but no,
It runs on a separate thread for each event but it’s an @AwaitingEvent so whatever you do on the event has to finish before the event completes

[lunar quail]

is there anything like bukkit's PluginDisableEvent on velocity?

[rich hawk]

no

[fossil sundial]

No because the plugin can’t be disabled.
But there’s a proxy shutdown event https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/proxy/ProxyShutdownEvent.html
If you need to do anything like write cached data before exit this is the one you need

[lunar quail]

I need my plugin to unregister other plugins from its API in case if someone uses some plugin like ServerUtils to disable or reload their plugin at runtime

[fossil sundial]

You cannot load unload or reload plugins on velocity

That will be done during restarts of the proxy

[lunar quail]

there is ServerUtils plugin, it uses some reflection stuff to do this

not sure if I should support such cases to be honest

[fossil sundial]

We’ve learned from the mess that is runtime dynamic loading and the horrible issues that come with it.
If at all Velocity may support soft restarts in the future

But we won’t support things such as this

[lunar quail]

so I probably shouldn't either, should I?

[fossil sundial]

If you want you can look at how that plugin did it. However be warned it will cause issues and it may break at some point because of internal changes

[lunar quail]

ok, thanks. one more question: where can I see the full list of fields that I can have with@Inject? and I'd also like to read about how this injection thing works, because there doesn't seem to be much information about it at docs.papermc.io/velocity

[digital rock]

Why has velocity Not implemented MiniMessage By default?

[bold wharf]

afaik it's part of the API now

[digital rock]

U sure?

[bold wharf]

afaik

it's part of the core of adventure

[digital rock]

No

[bold wharf]

make sure that you're targeting the latest snapshot

[digital rock]

3.1.1?

Isnt That the latest version?

[bold wharf]

3.1.2-SNAPSHOT

[digital rock]

Oh ok, I‘ll try out.

Thx

[wide tide]

ServerUtils calls ProxyShutdownEvent for the plugin that's being disabled

and if you really want to detect ServerUtils' disable action specifically, you can listen for the VelocityPluginDisableEvent (PRE stage) from the SU api

[burnt dragon]

minimessage isn't part of the core adventure API, it is a separate module

however it is included in velocity as of the latest snapshot version

[craggy pecan]

There's these https://github.com/PaperMC/Velocity/blob/aa38d3e561862d92c1a62f296cfdb6cdf983871a/proxy/src/main/java/com/velocitypowered/proxy/plugin/VelocityPluginManager.java#L134 and these https://github.com/PaperMC/Velocity/blob/aa38d3e561862d92c1a62f296cfdb6cdf983871a/proxy/src/main/java/com/velocitypowered/proxy/plugin/loader/java/VelocityPluginModule.java#L48

[opaque escarp]

Is there any reason why the ProxyServer interface extends the Audience interface instead of ForwardingAudience when the VelocityServer class that implements it does implement ForwardingAudience?

[burnt dragon]

sounds like an implementation detail to me

[restive idol]

Hello, how i'm supposed to ping a server to see if is online?

[fossil sundial]

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/server/RegisteredServer.html#ping()

No result/exception is thrown if offline

[restive idol]

There is any code example?

[fossil sundial]

Wdym, that code would be highly situational

So tell us what you’re trying to do

[restive idol]

I need to ping a list of subservers

To see if they are online

[fossil sundial]

Do you need the result right away

[restive idol]

What do you mean?

[fossil sundial]

you need to wait till the ping completes to get a result

That’s why I’m asking and that’s why the code is highly situational

[restive idol]

Yeah i know that

I needed some example just to understand how it works

[maiden hawk]

It returns a future

[restive idol]

On bungeecord is pretty easy, on velocity is a pain

[maiden hawk]

Why pain?

You can find many guides on how to use futures in Java

[fossil sundial]

ping().get() is how you wait for it to complete while blocking your current execution

That’ll throw an exception if no data is there

[maiden hawk]

[restive idol]

That means that the server is offline?

[fossil sundial]

Yes.

[maiden hawk]

Usually

[restive idol]

K seems easy then

[fossil sundial]

You’re in reality supposed to use .thenAccept(…) and .exceptionally(…) or .whenComplete(…,…)

[maiden hawk]

^

[restive idol]

Yeah i saw, thanks

[restive idol]

boolean isActive returns if player is connected to the server?

[lethal canyon]

How can I make a command for the plugin so that it reloads after the execution of the command, like:
/velobby reload
?

[frail spindle]

Hi, how can I create a shorter version of /server lobby, best would be if I could make it "/l"

[buoyant kayak]

does the BungeeCord plugin message channel (https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/) work the same in Velocity? (https://github.com/PaperMC/Velocity/issues/247)

[sour current]

yes

[buoyant kayak]

alright thanks

[vapid prawn]

Hi I'm getting this error and idk why, it should work fine.
The code:

@Inject
    public VMain( ProxyServer proxy, Logger logger, @DataDirectory Path dataDirectory ){
        this.proxy = proxy;
        this.logger = logger;
        this.dataDirectory = dataDirectory;
    }

[rich hawk]

you need to exclude signed files

from your jar

[vapid prawn]

I'm trying to use this library https://github.com/SpongePowered/Configurate

[vapid prawn]

But when the server starts that error pops up

[rich hawk]

exclude the signed stuff

https://stackoverflow.com/questions/34738653/maven-shade-plugin-does-not-exclude-the-manifest-signature-files for maven

[vapid prawn]

Thx bro!

[proven temple]

Thinking about switching from Waterfall -> Velocity. Can anyone give me a rundown of the major differences?

[bronze yoke]

https://docs.papermc.io/velocity/comparisons-to-other-proxies

[proven temple]

Thanks, does Velocity support plugin messaging out of the box, or would I have to make a custom plugin for this? I'm trying to move a player from one server to another within a bukkit plugin.

[bold wharf]

it implements bungees messaging channel

[proven temple]

Awesome

[turbid jay]

Hey. I'm starting with writing a plugin for velocity as my first java project. Now, there's the first choice: Maven or Gradle?

I've looked at a few other plugins for velocity, and it seems Gradle is a bit more common, which would of course help with me getting questions answered.

Another question is of course, is there a decent boilerplate project I could use?

[fossil sundial]

there isn’t really but I highly recommend using IntelliJ Idea and the minecraft development plugin to create the project; it sets up most of what you need to get started

[turbid jay]

Thanks! Got that going luckily 🙂 Doing development without a Jetbrains IDE would feel weird to me.

[boreal shore]

How can I check on proxy if message was send from player or server?

[bold wharf]

check the source of the message and instanceof it?

[boreal shore]

this doesn't work event.getSource() instanceof Player player

and I send plugin message like player.sendPluginMessage(...)

[bold wharf]

and you sent that from where?

cos, if you ran that code on the server, the source will be the server

[boreal shore]

from paper to velocity

[bold wharf]

also, see what that getSource() thing returns as I don't recall it being a Player instance directly that was returned but some other object

ah, yea, either Player or ServerConnection

but, if you sent if from paper, that's the server

[boreal shore]

oh, ok, so If I want to get player in the proxy I have to send their uuid/username via messages?

[bold wharf]

what?

[boreal shore]

I mean that player which I tried to get from source 😄

[bold wharf]

get it from the ServerConnection I'd guess

[rigid vine]

are there any velocity plugins, which are made with maven and use bstats?

[ashen fiber]

Maven is bad

[rigid vine]

yet still the only thing that works on my pc c:

[bold wharf]

you add the repo, and add a relocation pattern to the shade plugin

well, add the dep, idr if they use a custom repo

but, last I knew they documented how to do that

[rigid vine]
