[hidden gale]

Then, again using VarIntByte of Bungee

As i see velocity switched license.

[fossil sundial]

You can still do that but it has to be open-source

[hidden gale]

Well, i won't public my api, and bungee improvements

So i guess, backport again to the other thanks too.

[astral elk]

Anyone used the Velocity API to launch containerised servers on-demand?

I'm hoping to use Velocity as a launch proxy, and if the server isn't running, launch it (moving players from void lobby to their requested server once it reports online)

[vapid prawn]

Hi I'm developing a ban plugin, and I'm trying to check if the player is banned, and everything works grate, but when I deny the connection, it doesn't send any kick message, it just stays loading:
I check this in with the PreLoginEvent.
This is the code I use to deny the connection, but its not working:

e.setResult( PreLoginEvent.PreLoginComponentResult.denied( announcements.banPlayerKickMessage( ban ) ) );

[vapid prawn]

any solution here?

[vestal nymph]

moment i am stupid what does he want from me

[agile ore]

Plugin ids should be lowercase

[vestal nymph]

ok

thanks

This is my first velocity plugin

and puhh

hopefully i got all wright

is there no chatcolour?

[spiral portal]

Velocity uses Kyori Adventure

[vestal nymph]

what

[spiral portal]

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

[pallid reef]

Hi, I raised the issue yesterday but can someone fix the Velocity website to not point to a vulnerable version?

[spiral portal]

you can skip the Getting Started step as it's build in Velocity!

[agile ore]

https://github.com/PaperMC/velocitypowered.com/pull/43

[steel horizon]

Quick question, is there a way to add permissions like you can in the plugin.yml in Paper plugins? That LuckPerms for example is able to auto-complete them?

[vestal nymph]

i get this error but i havent even imported the plugin for the api in my plugin

ok fixed that

[pallid reef]

Did something about Velocity build break recently? I'm trying to build the code from git (as I've done many times) and it's crashing on me, with a spotbugs error: https://pastebin.com/V6q7cJAn

[vestal nymph]

this is my first velocity plugin, and what does this want to tell me

[pallid reef]

Update: I removed spotbugs from the build and I got a working jar, but this still perhaps should be looked into?

[flat pivot]

woah i never knew i am a dev

[vestal nymph]

what does he wants to say me

[rich hawk]

Send /velocity dump url and your build file

[vestal nymph]

build file?

is this like some gradel shit i dont understand

[rich hawk]

either your Pom.xml or build.gradle

[vestal nymph]

what is the command for the proxy to dump

because i cant connect to the server

[rich hawk]

/velocity dump

[vestal nymph]

console*

[rich hawk]

That but without the slash

[vestal nymph]

where does he dump it?

in a file because the console isnt showing anything

idk id it is just cloudnet

[rich hawk]

Type that command

[vestal nymph]

and here my pom

[fleet sail]

pom.xml by @vestal nymph: https://paste.gg/1404664922ef4192bc2345a25f563c4b

[rich hawk]

Don’t use 4.0.0

[vestal nymph]

ok

the intellij addon did use it automaticly

[rich hawk]

Use 3.1.1

[vestal nymph]

ok

is it tjust 3.1.1

or do i need to add like -SNAPSHOT

or some shit

[rich hawk]

No

Just that I think

[vestal nymph]

ok

after 300 maven errors i got it

Sometimes i want to throw maven against a wall

[knotty mica]

Just print out the entire source code of maven, then tie it to a rock

[vestal nymph]

ok

good idea

[steel horizon]

3.1.1 didnt work for me

[rich hawk]

???

[tender linden]

how do I build a simple text component?

for waterfall I did new TextComponent("text") but I can't figure out how to do it in velocity

[oblique haven]

Component.text("text")

[pastel bone]

When exactly is the TabCompleteEvent being fired? I'm debugging my listener right now because it seems like The TabComplete isn't being fired at all.. Docs are saying "This event is fired after a tab complete response is sent by the remote server" so technically if I'm tab completing a Player Name on the Server the Event should be fired right?

[bronze yoke]

pretty sure that only works for 1.12.2 and older

[pastel bone]

That would explain a lot hhaha.. So Is it even possible to Interfere with the TabComplete in any version above 1.12.2?

[vapid prawn]

Could some one help me out with this? plzz

[pastel bone]

can you show what this method is returning: "announcements.banPlayerKickMessage( ban )"

[arctic lichen]

How can I get the SQLite driver running on Velocity?

[craggy pecan]

You will need to shade it (there are plugins for both Maven and Gradle)

[vivid plover]

Hi, is it required to shade the velocity API or can I just set it to compileOnly?

[agile ore]

You don't have to shade it

[vivid plover]

alright thanks

[wary tiger]

You can't safely shade the SQLite driver in a public plugin, because it is impossible to relocate JNI libraries

[bold wharf]

use h2 (Well, take a look at)

iirc it's faster than sqlite and is generally much more stable

[flat bolt]

hey is the velocity to 1.18?

[agile ore]

yes

[flat bolt]

Could I ask you for a link?

[slender fulcrum]

google.com

[fossil sundial]

https://papermc.io/downloads#Velocity

[coral haven]

I'm trying to write a plugin for velocity and I'm getting the following error

Did not find a valid velocity-plugin.json

can't find anything on google

or on the actual documentation

I'm using Velocity 3.1.1

[rich hawk]

Kotlin / maven / gradle?

Use kapt

[coral haven]

Kotlin and Gradle

k

what is kapt?

[rich hawk]

https://kotlinlang.org/docs/kapt.html#using-in-gradle I think

[shut imp]

how would i use color here in this message? https://github.com/PaperMC/Velocity/blob/292b2f96ab8d65a9982dd787c626d1060e5472be/proxy/src/main/java/com/velocitypowered/proxy/VelocityServer.java#L533

would it be Component.text("Proxy shutting down").color(TextColor.color(123456));?

[rich hawk]

Yes

.adventure

[fleet sail]

[shut imp]

thanks 🙂

[coral haven]

I got it working thanks

very pog

Is there a way to depend on maven dependencies without shading? I try to avoid making mega-jars

[rich hawk]

Yes slimjar or make your own (or just shade :p)

[shut imp]

where would i find a list of TextColor.color codes then? im a noob at this

i think the docs made me more confused than it should of 😄

[rich hawk]

You can use NamedTextColor

TEXTColor.color is for hex codes iirc

[shut imp]

ah

so would Component.text("Example text here").color(NamedTextColor.GREEN)); work for example?

[rich hawk]

Yes

[solid ivy]

@fossil sundial Btw, do you have specification/example implementation of that networking thing you talked before?

[gloomy radish]

Hi, can I send a message plugin to velocity so that it will transfer the player from server to server?

[bronze yoke]

yes, use the same channel bungeecord uses

bungeecord:main iirc

[exotic nacelle]

I am trying to migrate to Velocity 3.0.0 and have this problem

[bronze yoke]

.adventure

oop that doesnt work here

[exotic nacelle]

If I change the data type to Component it will complain that it cannot import String to Component from Config

[bronze yoke]

use LegacyComponentSerializer

or ideally minimessage

[exotic nacelle]

it only has midimessage

[bronze yoke]

what?

[exotic nacelle]

javax.sound.midi

[bronze yoke]

yes so add the library

[exotic nacelle]

No matter which of the two I use, it shows an error

I'm not good at Java btw

[bold wharf]

You can't just cast random things to random things

It expects a Component

[covert folio]

learn java first then

[bold wharf]

the legacy serialiser has methods to parse the legacy formatted strings into Components

[gloomy radish]

thk

[exotic nacelle]

Where can I find them and how do I use these?

[bold wharf]

don;t mention

look at the methods on that class

[tender spruce]

is there a way to get a players inventory on the proxy? Im guessing not

[frigid rivet]

No.

[tender spruce]

Yeah figured as much. Can you talk with a mod on a server?

[frigid rivet]

Huh?

[tender spruce]

Like have your plug-in send and receive data from say a fabric mod on a server

[frigid rivet]

Yeah, you can use plugin messages.

A Spigot plugin will also work.

I don't know the best place for documentation on either.

[tender spruce]

Oh perfect. Is there any examples of this being used? If not I’m sure I can figure it out

[opaque escarp]

https://github.com/Exceptionflug/protocolize/wiki/Inventories#manipulating-the-player-inventory

[tender spruce]

Oh this is very cool. Is there similar things for like player health and xp and other info? If not no worries

Oh it has custom packet support liiiit

[gloomy radish]

Hi, how do I get a Player that executes a command?

[robust mural]

CommandExecuteEvent

[gloomy radish]

and you can do it inside the command code:?

[robust mural]

you're making a command?

I do not understand exactly what you mean

[steady trellis]

Invocation#sender

[gloomy radish]

I don't see it

[coarse topaz]

That depends on the type of command you create, if you are using SimpleCommand or RawCommand see https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/command/CommandInvocation.html

[gloomy radish]

I don't understand what should I use so that I can get a player executing a command

[fossil sundial]

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/command/CommandInvocation.html#source() check instanceof Player and then you can cast to player if true

the api-provided possible senders are ConsoleCommandSource and Player

if its neither it was likely added by a plugin

if its a brigadier command you already have the source provided

[gloomy radish]

another question for some reason I don't have a command written in velocity on my servers associated with it (it only works in the velocity console)

[fossil sundial]

Yes. The commands are only available to players connected through the proxy or to the proxy console. If you need to trigger a command from a server on the proxy you should look into plugin messaging (to make a message that triggers it on the proxy from the server) which requires a plugin on the server.

[gloomy radish]

[tender spruce]

How can you send plug-in messages from a server to the proxy? I figured out the other way round

[frigid rivet]

https://github.com/Camotoy/GeyserSkinManager/blob/master/spigot/src/main/java/com/github/camotoy/geyserskinmanager/spigot/listener/SpigotBedrockSkinUtilityListener.java#L50 here's how I did it.

[tender spruce]

Thanks 👌

[cursive jolt]

Does the API allow to listen for packets from players? I want to analyse and possibly block some packets from players on a proxy level

[agile ore]

you can maybe do some reflections

[gritty valve]

How do I issue permissions to a player?

[round quiver]

Hey, a question, which event is called first PlayerChooseInitialServerEvent or LoginEvent.

[covert folio]

Login

[round quiver]

thx

[stone tulip]

Is there a plugin that will make velocity show the names and player counts of each server instead of the ~12 players normally shown in the multiplayer server list (which velocity seems to never give a listing of)?

[blazing kernel]

Is velocity thread safe ?

[oblique haven]

depends on what you're doing

[blazing kernel]

calls like getting all players, kicking player, changing player's server

[oblique haven]

I believe all of this is thread safe

yes

[blazing kernel]

ok thx

[oblique haven]

please someone correct me if I'm wrong

[fossil sundial]

Unless you’re blocking an event you’re good.

[blazing kernel]

no, i won't block, thx

[fossil sundial]

tho no guarantees that properties of the players stay the same while you’re executing stuff

[fossil sundial]

do keep in mind that the connection request is also a type of event callback; but you’re likely only hurting yourself by blocking somewhere there

[blazing kernel]

and with the scheduler ?

but shouldn't datas be accessed by one thread at a time ?

[bold wharf]

the proxy itself is designed to be reasonably safe

as for anything else, it's 100% on you to ensure that your own logic is thread safe, etc

[blazing kernel]

oh ok

[pearl pulsar]

Velocity/proxy updates its available commands when I run "https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#updateCommands()" on the Paper/server. Is there an easy way to do this directly on the proxy knowing that it wont fetch the available commands for the Paper/server that the player may be connected to?

[craggy pecan]

Iirc issuing updateCommands from the backend server also rebuilds the command tree in the proxy, so the proxy commands also get updated

There's no current way (other than switching servers or reconnecting). You can also send a message requesting the backend to send an update

I'm not sure about the safety aspect of this, Five probs knows more about this

[bold wharf]

the proxy would need to store every players command structure from the server in order to recalc it on its side

[fossil sundial]

You generally shouldnt update that at all. The client only expects it once but velocity tolerates it nonetheless

[analog dew]

I'm 90% sure that's not true and that the vanilla server resends the list to a player when they're opped/deopped

[fossil sundial]

I’d love to be proven wrong; if you know more do please correct me

[bold wharf]

it does

otherwise when you're op'd you'd need to relog to see the commands you're able to use now

[pearl pulsar]

Yea, I do understand that, however, I’m not connecting the user to any backend server, and just wish to display and update the players available commands on the proxy accordingly, but understand it is not possible atm

[bold wharf]

basically, it's doable

Just, you'd need to hook in somewhere and store the command structure from the client

to update it, you'd then need to pipe it through the logic in velocity which adds its commands

which, for the sole purpose of potentially needing to resend commands what is often once in a blue moon, is pretty bleh

if this is for personal use, can just basically get a plugin setup to send a message over to the backend to resend the structure def

[vivid valve]

Can you give log messages a color like you can do on Spigot and BungeeCord?

[craggy pecan]

I think this was discussed, and Tux essentially said the same: it isn't worth it to cache the entire command tree from the backend

[low crypt]

Does Velocity have some sort of ServerSwitchEvent?

[low crypt]

update: realized ServerConnectedEvent contains a previousServer field

[agile ore]

that was fast

[low crypt]

How would you apply a certain permission to a player?

I see hasPermission and getPermissionValue within the PermissionSubject class, but I cannot find how to update permissions for a player.

[agile ore]

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/permission/PermissionsSetupEvent.html

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/permission/package-summary.html

[fossil sundial]

Basically you don’t do that within a non-permissions-plugin
The cleanest way to do it anyway would be to depend on your permission plugin like LuckPerms

[low crypt]

Yeah, I ended up making my own permission handling class which hooks into one of my other plugins

[quaint canopy]

Hey,

I got the following error: https://pastebin.com/pvhMVwQT
This is the source code: https://github.com/Katzen48/minecraft-ingress

I don't quite understand, where that error comes from.

[craggy pecan]

Could you please open a ticket on https://github.com/LanternPowered/Lmbda?

[low crypt]

i'm literally in love with velocity and its api

[agile ore]

same

[glacial kraken]

hi guys

i wanna make a multi-platform plugin

and i have plans to support velocity

i never made a velocity plugin before

from docs

it says there is no plugin.yml at all

and from some open source plugins

99% of plugin code is in 1 class

im wondering why

does velocity not load other classes or something

[analog dew]

what

[glacial kraken]

see this

https://github.com/Minecrell/ServerListPlus/blob/master/Velocity/src/main/java/net/minecrell/serverlistplus/velocity/VelocityPlugin.java

the whole plugin in 1 class

well since its a multi-platform its not "the whole plugin" but still confusing

i see subclasses instead of just new classes

[oblique haven]

this is a very unique way of doing it

https://github.com/CoreyShupe/MinecraftProxyLoadBalancer something like this is multi platform but probably more understandable

@Plugin(
        id = "velocity-load-balancer",
        name = "VelocityLoadBalancer",
        authors = {"Corey Shupe (FiXed)"},
        url = "https://github.com/CoreyShupe/VelocityLoadBalancer",
        description = "Simple load balancer plugin for velocity networks.",
        version = "0.0.1"
)
public class VelocityLoadBalancerPlugin {``` the main part which replaces the plugin.yml is this

the @Plugin dec makes it auto-generate a json file in the root

you should never write your own json file

[glacial kraken]

interesting

[oblique haven]

https://velocitypowered.com/wiki/developers/creating-your-first-plugin/

[glacial kraken]

thx for letting me know about that

[oblique haven]

this is a great wiki to follow

btw

[glacial kraken]

im already in this wiki lol

[oblique haven]

It's a good one 😉

goes over everything you'll need to know

for everything else you can dig into the javadocs

(don't know where they're hosted though)

[glacial kraken]

thx anyways

[oblique haven]

👍 sure thing

[oblique haven]

can we see how you declared the event listener

and the imports

Glad I could help 🙂

[glacial kraken]

lmfao

lol

[glacial kraken]

so since i do it with an annotation

@Plugin

processResources {
    from(sourceSets.main.resources.srcDirs) {
        filter ReplaceTokens, tokens: [version: version]
    }
}```

will this work

this should replace @version@ with the version

[vivid valve]

How do I check the server the player will be sent to when he gets kicked from a server? I can't find a option for that in the KickedFromServerEvent
(Ping me)

ah set the result to RedirectPlayer class I guess

[glacial kraken]

No one responded to this..

[glacial kraken]

It looks like a plugin doesnt even spectify the version

Is that allowed in velocity?

[glacial kraken]

how can i send a colored message that also support &

[rich hawk]

LegacyComponentSerializer

Or better, use mini message

[glacial kraken]

thx

[glacial kraken]

TabCompleteEvent does not fire

ive tried to debug

[fossil sundial]

Yes, however it is discouraged

[fossil sundial]

That doesn’t fire on commands. If you need to use tab-complete with commands please look into BrigadierCommands or the simple velocity commands

[glacial kraken]

i would like to get the event

when client asks for the tab complete

/paper <version>

as soon as i click space after paper

the event should be fired

but this doesn't happen

if this isn't possible tell me i can use packets from protocolize

[half locust]

what's your end goal?

[glacial kraken]

im trying to remove some things

like

/tp

[fossil sundial]

That doesn’t fire because it’s a command that belongs to the brigadier structure downstream. Interjecting there would be hacky at best which is why we don’t support it

[glacial kraken]

remove some players

[glacial kraken]

so simply i will have to go look into packets, right?

[half locust]

sounds like you're trying to do stuff proxy-level which should be handled at the backend level in the implementing plugins

[glacial kraken]

im trying to help the user so he doesn't have to install the plugin on every backend

ok well my minecraft crashed, my pc can't handle all of this at the same time

[fossil sundial]

It won’t be that simple because brigadier isn’t exactly a very easy subject.
You’re way better off doing this with a plugin on the backend. But we can’t stop you from attempting it anyway

[glacial kraken]

its a multi-platform

it works on backend

(with packets)

i just know the user will not like installing the plugin on every backend*

[fossil sundial]

If you register a command with the same name on velocity then it won’t ever go through to the backend
That is if I’m not mistaken and the overlap bug doesn’t exist anymore

[glacial kraken]

this isn't how it will work at all

ok ill do it with packets

PlayerAvailableCommandsEvent is fine?

its fired

[fossil sundial]

It’s fired but there is no result

[glacial kraken]

actually it works perfectly

modifying the root command works

[fossil sundial]

That might have been introduced sometime but the user can still run the command but it won’t complete

[glacial kraken]

running the command is not an issue at all

[fossil sundial]

I forgot this isn’t a transparent event anymore

[glacial kraken]

im sorry but what is a transperent event

how do u test velocity plugins, my game is now crashing bc of ram overload

[fossil sundial]

An event that is fired just to inform plugins of something. There is no result and the code just continues running

[glacial kraken]

oh okay

i am afraid there is no way to modify the tab complete from proxy

im waiting for protocolize support to help me with this

[fossil sundial]

Well

[fossil sundial]

This event works for 1.13+ while the tab complete event works for everything older

[glacial kraken]

im also making a free version of a premium plugin so

[glacial kraken]

wait

if i use 1.12

tab complete event will fire?

[fossil sundial]

I mean it should

Unless you have ViaVersion on the proxy

[glacial kraken]

ok well, i will stick with packets

[glacial kraken]

does it even support velocity?

[fossil sundial]

Yes. Even better than it supports Bungeecord

I would know seeing as I’m on the Via team

[glacial kraken]

bungeecord does not support anything

if it was allowed i was gonna swear at it

[worldly granite]

how can I make a plugin that can load on multiple platforms

i.e. velocity, paper, waterfall

i want it to work on all of the above

i know bungeeapi

[bold wharf]

each of them have different files to say what is the main class

so, you basically have different main classes for each of them, each with their own module, and shade/shadow it all into one jar, basically

[craggy pecan]

1.13+ clients don't even send packets asking for tab completions in most cases. That's why TabCompleteEvent no longer fires for these clients.

Your solution seems like the best option

[worldly granite]

what would a good multi-module structure look like i dont do that often with maven

right now i just have a couple classes thrown into one

obviously this isnt perfect

ignore how theres only one class im using this as a learning tool

also how the hell do configs work in velocity it hurts my brain

we arent in kansas anymore

[glacial kraken]

plugin.yml and bungee.yml ok well that's messed up

u need diffrent modules

[fossil sundial]

Not necessarily

[glacial kraken]

no idea but i use a liv

[glacial kraken]

it is

[fossil sundial]

Sponge configurate

[fossil sundial]

In what way?

[glacial kraken]

so u dont accidently use bukkit stuff in velocity classes

so it break on velocity

[fossil sundial]

That’s not necessary it just protects you from your own stupidity

[glacial kraken]

its not stupidity

its a mistake we all do

[fossil sundial]

As long as you don’t have any static fields in those classes you’re good

[glacial kraken]

if our ide is stupid

[fossil sundial]

It’s good practice to do so

But it is in no way necessary

[glacial kraken]

i tried making a plugin this way

and i broke it

ik its my own mistake

but i still dont like it

btw since velocity support is active does anyone know how to use protocolize

its been 11 hours no one responded in their discord

i need help

[fossil sundial]

Can’t really help you with that
Don’t know anything about it and plus I don’t like the concept
I’m still firm on believing packet manipulation is best done downstream

[glacial kraken]

looks like i need to find another packet lib

[glacial kraken]

my game crashed after im done with testing, my pc is 85% ram without minecraft

this is painful when debugging

[worldly granite]

?

[fossil sundial]

You’re developing a plugin if I’m not mistaken? Velocity provides the sponge configurate library including the most common drivers like hocon

[worldly granite]

Is there a guide or an example for using that library

[fossil sundial]

We don’t have one but sponge has one in their how to create a sponge plugin wiki

[worldly granite]

It doesn't make the most sense to me since it uses a lot of Sponge classes that arent available, is there an example in Velocity?

[craggy pecan]

Check the wiki of Configurate on GH

[worldly granite]

with PlayerChatEvent, if i return an EventTask, will it wait for the task to finish excuting before it reads isCancelled
(im asking if i can cancel the event asynchronously)

[worldly granite]

wait

[ashen fiber]

com.velocitypowered.api.plugin.InvalidPluginException: Did not find a valid velocity-plugin.json

Either you didn't run the annotation processor, or you excluded the result from your build somehow

you've got to do something special for kotlin, what that is I'm honestly not sure though

[rich hawk]

Yes

Is Velocity updating to 2.17.0 on Log4J, it seems like it shouldn’t affect servers out of the box, but I’m also not certain

Ah there we go lol

[trim forge]

Howdy - currently making a player balancing system for hubs but ehhh, I appear to have done a yikes. If one of the servers cached as a hub server is offline, velocity basically bricks itself and crashes - is there any way to check if a server is online before a player connects without putting masses of stress on the proxy? TIA!

Something like a server start event / server quit event that I've missed maybe?

[bronze yoke]

ping the server and wait for the response

[trim forge]

Will that not be quite intensive on high player counts moving around the network though?

As in if a server closes and like 300 players move from one server to another, will that not kill it a bit?

[trim forge]

Is there like a built in way that I can check if a server is online? Something like a #isOnline method?

This is driving me insane 🤣

[bronze yoke]

make it ping every x time and cache if it’s online or not

[trim forge]

Alrighty, I was hoping there was a better way but I'll do that.

Thank you!

[fossil sundial]

The proxy can only do the same thing if you think about it; it’s not ideal sadly

[tidal belfry]

How do you listen to packets directly on velocity?

Is there an existing api for it?

[frigid rivet]

No.

Generally if you're trying to listen for packets on the proxy you should consider if your application is better purposed for the backend servers.

But there are APIs such as Protocolize that allow you to work with packets, though it's generally frowned upon.

[spiral thunder]

Hey, is there a way to disable this try section.

I'm trying to develop a hub spreader plugin, but it's forcing me to hub1 now

[fossil sundial]

No; but you can just listen to the ChooseInitialServerEvent to modify the behavior

[spiral thunder]

Alrighty, thanks

[spiral thunder]

Next question,

Is there a way to check if the player specifically has a permission node, without hooking into a permission plugin like LuckPerms?

[burnt dragon]

hasPermission ?

[spiral thunder]

That'll include * permission

[burnt dragon]

well, that depends on the permission plugin

[spiral thunder]

Well, we use luckperms

I wnat to use the plugin on every proxy, no matter what permission plugin

[burnt dragon]

whether or not a star node is resolved depends on your permission plugin

[spiral thunder]

Hm okay

[burnt dragon]

but the hasPermission check will delegate to your permissions plugin (if it's doing stuff correctly)

[fossil sundial]

That’s by design of the permission plugin.
Velocity doesn’t interfere here

[manic pumice]

I'm trying to migrate a plugin that used plugin message channels from bungeecord to velocity.
I've found that the implementation of the message channels differs between the two. For server related queries bungeecord writes the requested subchannel name to the buffer before checking if the server exist and adding the rest whereas velocity does not return anything if a non-matching server is not found.

https://github.com/SpigotMC/BungeeCord/blob/master/proxy/src/main/java/net/md_5/bungee/connection/DownstreamBridge.java#L414-L428
https://github.com/PaperMC/Velocity/blob/dev/3.0.0/proxy/src/main/java/com/velocitypowered/proxy/connection/backend/BungeeCordMessageResponder.java#L103-L108

I had used this to detect if a server had been removed when polling for "PlayerCount" to remove a clickable NPC in the lobby. Should the velocity implementation work in the same way as bungeecord? Is there a native way to check for this? or should I search for a solution outside of plugin messaging channels. Cheers.

[fossil sundial]

It should work the same. I’m going to take a look at it later and get back to you

[spiral thunder]

What event is called when some of my spigot servers restarts? @fossil sundial

[frigid rivet]

I don't see how Velocity would have context that a server restarted.

[fossil sundial]

KickedFromServerEvent
You can set a server to redirect the player too

[spiral thunder]

How would I be setting the server?

[fossil sundial]

You set the result as KickedFromServerEvent.RedirectPlayer

[spiral thunder]

aight

ty

[fossil sundial]

Basically setResult(KickedFromServerEvent.RedirectPlayer.create(server));

[trim forge]

Thanks for the response - this is the conclusion I came to! I've decided that I'll probably use some sort of redis cache to communicate between the proxy and spigot server so that I can keep information updated and balance accordingly. Appreciate the help!

[gritty valve]

Does speed support multithreading?

[bronze yoke]

yes

speed

[gritty valve]

velocity*

[analog dew]

now you too can calculate displacement over time async

[fossil sundial]

There is no main thread context in velocity and the rest uses a thread pool; so having multiple cores available is best for velocity

As for events; they roll as their own thread
They only differ in if they block or not

[glacial kraken]

How can i get a resource from jar

Im velocity

Without messing with other plugins that have same resource file

[bold wharf]

you get the classloader of the jar and then you can get a stream or something from the classloader to a file in the jar

[glacial kraken]

No idea where to get the class loader

[bold wharf]

don't mention

[glacial kraken]

Oh sorry

[bold wharf]

getClassLoader on a Class object iirc

I mean, velocity is nothing special here, this is something easily googleable as it's a 'basic' java thing

[glacial kraken]

Do i get class loader on main instance?

[bold wharf]

of your plugin? sure

[glacial kraken]

Sorry i didn't know its java thing

I dont interact with class loading lol

[green dune]

Hey, I need some clarification. If I used EventTask.async() on my PreLogin listener, would PostLogin wait for it to finish or no? Because I have my PreLogin listener grab data then have it put in a hash map. The PostLogin listener would then get the data from the hash map. But how I have it currently, sometimes the data wouldn't be present for PostLogin to access.

[fossil sundial]

How is it PostLogin supposed to wait?
The answer is no but I have a proper solution for you.
Fire a CompleteableFuture with the get-code and the value you want as return from the PreLogin, put that future in the map and then on PostLogin/Login block the listener with the same future (get it from the map) using .complete() on that future
It’ll wait for the task in the future to complete if it hasn’t already completed and then return the data

[green dune]

Ah, tysm!

[fossil sundial]

If you aren’t adept with using Futures feel free to ask

[green dune]

I'll mess around with it in my free time

[maiden hawk]

Hi, does velocity have any main thread? If not, will blocking on a event not marked async slow down the proxy?

Using debugger I have noticed that the original "main" thread is used for console input, tho that doesn't mean there isn't any other main thread.

[fossil sundial]

It will not slow down the proxy, but it will block the event (as implied)
That only happens on ResultedEvents, the other events aren’t waited for (for obvious reasons)

Also if you wait too long on some events then the client or server will time out

[maiden hawk]

OK, so what if another one of the same type fires while the first is still blocked? Will it just run on another thread, or wait until the one before is done?

[fossil sundial]

If will just run. Events and everything else uses a thread pool and there isn’t a hard limit to the amount of things running at once (except for processing power and memory)

[maiden hawk]

Does this also include commands?

[fossil sundial]

Yes.

[maiden hawk]

Great! Also will the command event on bukkit run even when a velocity command was executed? And vice-versa?

[fossil sundial]

No; if you register a command on velocity it will not be forwarded to the server
You can make a plugin do that though

Vice-versa- velocity doesn’t handle command that aren’t registered, those are just passed through

[maiden hawk]

So when I would want a player to not execute any command, I would need to block the event both on velocity and bukkit (Paper)?

[fossil sundial]

Don’t misunderstand; There is no event for that on Velocity
If you want to block/remove a proxy-provided command you either need to deny the permission to use it or you have to overwrite or unregister the commands

But the paper part is true

[maiden hawk]

if there isn't an event for it, what does this do?
https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/command/CommandExecuteEvent.html

[fossil sundial]

I didn’t know we added that

[maiden hawk]

Oof

[fossil sundial]

It may do what you want; though I haven’t ever used it before so I’m not aware

[maiden hawk]

So I guess I will have to try on my own

Anyway thanks for the explanation!

[fossil sundial]

Tho

Even if that event does what you want

It won’t stop commands from completing for the user

[maiden hawk]

To put this in context, I am creating an authentication plugin, which should be ideally placed only on Velocity

I am aware that I cannot block events like move etc.

But I would love to at least block the commands, otherwise I would need to add a counterpart for Bukkit.

[fossil sundial]

That’s possible; but blocking player from tab-completing commands will be a lot harder

Mainly because that’s not supported in the api

[maiden hawk]

oof

couldn't I make use of this?

https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/command/PlayerAvailableCommandsEvent.html

[fossil sundial]

Since that isn’t a resulted event I need to check if the output of that is ignored

[maiden hawk]

Well that wouldn't really match this description:

Allows plugins to modify the packet indicating commands available on the server to a Minecraft 1.13+ client.

[fossil sundial]

Would you look at that; this has to be the one exception to the rule of blocking non-resulted events

Yea that event is going on the list to be a bit more proper for polymer

[maiden hawk]

Well, is a better documentation planned?

Because the one on https://velocitypowered.com/wiki/developers/
Is pretty... brief.

[fossil sundial]

Well I do agree

But at the same time the team is lacking the time for more

Plus I have a mountain of features waiting to be implemented

Which I’ll be crunching away at over after Christmas

[maiden hawk]

I completely understand that, but it really sucks for new users. I needed to go through 3 velocity plugin source codes to at least understand how to do some thingies.

thank god I am using ACF so I do not need to mess much with commands

[fossil sundial]

You’re not alone with that
The only people that I haven’t seen complain are the people coming from sponge

[maiden hawk]

Well afaik the Sponge docs aren't really great either, so it makes sense.

[fossil sundial]

The api concepts are similar;

[maiden hawk]

I guess, I've never developed thingies with Sponge.

[fossil sundial]

And we do use a lot of sponge libraries

Including configurate and quite a few other things

[maiden hawk]

Oh configuration api

I've just imported external YAML lib

To make configurations

:)

[fossil sundial]

Yea that works; but you should shade and relocate that ideally

[maiden hawk]

I should, but considering my plugin will be probably the only next to LP running on velocity

I do not really care

But maybe when I'm done with this, I will take a look on Velocity and try to contribute somehow. I see you guys really need help.

@fossil sundial Also, are there some large networks that actually use Velocity? If yes, how much can a single proxy handle? (assuming unlimited cores, RAM and bandwidth)

From my experience the limit on Bungee was about 500-1000 players

So I hope it's better on Velocity

[fossil sundial]

Java does have a point of diminishing return with a single instance; that said I had a scenario in which I ended up pushing a single instance to about 1800 players

[maiden hawk]

So, clustering is still a must have for large networks?

[fossil sundial]

No idea where the absolute limit is

[fossil sundial]

For availability alone yes;

[maiden hawk]

I mean it all depends on HW, in ideal world more cores would mean more performance

But I am afraid this ain't the case

[fossil sundial]

But velocity still does provide a good amount of resource usage reduction over bungeecord

[maiden hawk]

But is it able to utilize very powerful machines tho?

[fossil sundial]

Depends on how you define powerful, the more cores you have and the faster the memory speed the better

But even that somewhere has a limit

[maiden hawk]

Well would it be able to fully utilize a 64core EPYC CPU?

or it will reach it's architectural limits by then?

[fossil sundial]

The 1800 player benchmark was achieved on a 2017 32-core Xeon with 3200mhz ECC ram

[fossil sundial]

You can probably push it a lot more with that kind of processing power though

[maiden hawk]

Did those even exist in 2017?

Wasn't it 16c/32t?

[nova radish]

Can you get a players coordinates from a velocity plug-in?

[fossil sundial]

No, velocity doesnt track that data

[fossil sundial]

no, it was a 64-core cpu but half disabled, those were sold as such in the scaleable-phi lineup

the phi-lineup scaleable processors at that time only had 2400mhz memory, this chip was "special" for having a different controller

theyre fom Q4'16

if I end up having access to that again Ill get the serial number

[green dune]

Is there a way to deny login and also prevent the particular connection from being logged?

[fossil sundial]

With a custom log filter that should be possible
But I don’t think there is another reasonably supported way

[maiden hawk]

Do you know the exact model?

I would like to see how it compares to a modern EPYC cpu

Or was it an Engineering Sample?

[maiden hawk]

@fossil sundial Oh god, it looks like ACF is only for Velocity 1.x, do you know any other solid command api?

[fossil sundial]

Velocity has brigadier

But I have to confess I still dont have a clear grasp of how to use that myself

[maiden hawk]

Well, from my today first use impression, it looks like Velocity is very chaotic

And I might consider using Waterfall

:(

[fossil sundial]

I may be one of the few velocity developers but that doesnt mean I have grasp of the entire project

[silent needle]

im not sure if cloud works with velocity 3, you could try that

[maiden hawk]

Hmm, I was recommended https://github.com/Revxrsal/Lamp this on ACF discord

[fossil sundial]

all I can say is that updating from 1.x to 3.x requires about two modifications at most

[maiden hawk]

Really? I will fork ACF and attempt to repair it

[fossil sundial]

I looked at just now and it seems to me like it is already updated for 3.x

[maiden hawk]

It ain't

it fucks up on load because it uses wrong Component api packages

Here is their pom

https://bin.kyngs.xyz/xedasagide.xml

[fossil sundial]

https://github.com/Revxrsal/Lamp/blob/master/velocity/build.gradle compileOnly 'com.velocitypowered:velocity-api:3.0.0'

[maiden hawk]

Yh Lamp is updated to 3.0

But ACF isn't which would suck

I will try to update it

[fossil sundial]

ah

Ill run my update script on it to see if that produces something usable

¯_(ツ)_/¯

[maiden hawk]

I will do it manually, thanks for the effort!

So far it looks like only the Component api is broken

[maiden hawk]

a lot

But I hope I will figure it out

[fossil sundial]

just replaced with kyori/adventure

also simplecommand changed a bit

not sure if thats applicable still

[maiden hawk]

ACFVelocityUtil, VelocityCommandCompletions are broken

And others probably too

But I didn't check them, cause I am currently fixing completions

[fossil sundial]

https://github.com/X-Niter/BetterDiscordBridge/pull/2/commits/d66f692fa670f0416d545d879135898b91c3ebe9 this might be helpful

thats what my rigged script does for reference

[maiden hawk]

Unfortunately there were more fundamental changes than references

Specially the Chat Color

which is RGB in new

But the api used standard §x

But I fixed that

@fossil sundial It's far worse than I thought

3/4 classes are broken

And it has literally no documentation

[burnt dragon]

cloud supports velocity 3, if you're looking for a command framework

[maiden hawk]

I know, but it would be nice to use ACF, cause I am already used to it

[burnt dragon]

yeah that's understandable, although they're really not super different, especially if you use cloud annotations

[maiden hawk]

So Components fixed, Command api remaining

[maiden hawk]

Aand done

@fossil sundial So it looks like 3 people already did the same thing as me lol

Well there goes 4th PR for velocity update

@fossil sundial BTW, commands executed which do not match any velocity command appear in the event too

And you can cancel them.

Also that command list thingy is completely useless

[kind lynx]

Hello, is there any full documentation for velocity 3.1.1? I need it to develop plugins for my server. Thank you!

[maiden hawk]

Unfortunately this is the only documentation available, however it is pretty brief.
https://velocitypowered.com/wiki/developers/creating-your-first-plugin/
But javadocs will help you: https://jd.velocitypowered.com/3.0.0/index.html

[kind lynx]

Well...

Maybe you can say me, how can I send player to another server...

This is only for velocity 1.x.x https://velocitypowered.com/wiki/developers/porting-from-velocity-1/

[maiden hawk]

No idea

But I need it to

Lemme check

[kind lynx]

Okay...

Maybe anyone who know how it does work can help us.
Can anyone help us?

[maiden hawk]

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

Take a look at this

[trim forge]

Having a bit of a weird issue, I'm listening to the KickedFromServerEvent so that I can catch any players that get kicked from a server and balance them in the best hub accordingly. Issue is, for some reason, it doesn't actually connect them to the hub. All the logic processes, and the code listening for initial player join hub balancing also balances them correctly, but the KickedFromServerEvent just kicks the player from the proxy when I #createConnectionRequest(server). Anything I've missed? Thanks!

[burnt dragon]

are you using the redirect player result?

[trim forge]

Usually use player#createConnectionRequest(server)#fireAndForget, but you're also able to set the server in some specific events, such as the PlayerChooseInitialServerEvent (#setInitialServer).

[trim forge]

No, I'm just listening to the KickedFromServerEvent and then creating a connection request to the hub that is deemed ideal.

[burnt dragon]

the event accepts a result that tells velocity where to send the player

you should be using that

[trim forge]

Am I just blind?

Oh yikes

[signal dagger]

ehh, quick question:
Just HOW breaking is Velocity 1.1.10 -> 3.1?
I've been very inactive over the last few months

[burnt dragon]

https://velocitypowered.com/wiki/developers/porting-from-velocity-1/

[signal dagger]

I'm asking because of my plugin (shameless self-advert while I'm at it https://github.com/itsTyrion/AntiVPN)
I just added Waterfall/Bungee support but realized it's still on Velocity 1.1

[signal dagger]

ty

[trim forge]

Just out of interest, would you recommend using iphub for an AntiVPN? I know of a few servers that do but I've never been certain quite how reliable / up to date it is. Have you had a good experience?

[signal dagger]

Can't comment on that.
I barely tested it but it seems decent on the first glance.
I'd heavily prefer to still have iplegit.com around (I actually planned to combine both!), but, very unfortunately, they shut down without a trace at some point in the last few months :/

[signal dagger]

But the fact that the API docs state to NOT cache for more than 24h, or 1h if it's really critical, seems to indicate that they're updating regularly

[kind lynx]

Thank you!

[signal dagger]

Dang, NOTHING red, just a recompile

[maiden hawk]

Very, Components and Commands will probably break completely, tho Components only need reimport.

[signal dagger]

I mean I already used the new components in all my Velocity plugins as soon as 1.1.x had them.
(And in this plug-in, I only use the serializer and 2/3 events)

only had to recompile

[maiden hawk]

So did you upgrade without an issue?

[signal dagger]

yup

[maiden hawk]

Wow

Lucky one

[signal dagger]

well I don't use any commands, only the LegacyComponentSerializer, and 3 events ((Pre)Login and ProxyPing) in this plugin

[maiden hawk]

Well then you should be fine, but if I were you I would check whether it really works

[signal dagger]

I think I should make a forum post.
6 DLs is not a whole lot
actually.. there's probably already a WAY better plugin out there sooo

[glacial kraken]

it looks like permission checks cannot be done on some packets sent before join (returns false when true)

is there a way to bypass this

[fossil sundial]

Can you elaborate please?

[glacial kraken]

let me commit my changes and tell u wait

using protocolize listening to that packet

https://github.com/BlueTree242/AdvancedPlHide/blob/develop/Velocity/src/main/java/tk/bluetree242/advancedplhide/velocity/PacketListener.java#L58

permission check return false

goes badly

player.hasPermission("plhide.blacklist-mode")

[fossil sundial]

Well first of all direct interaction with packets is unsupported for this exact reason

Secondly

[glacial kraken]

i had to cancel the packet as this is a security problem

[fossil sundial]

GameProfileRequestEvent has to be completed for the PermissionsSetupEvent to fire

[glacial kraken]

if player is not active, event not sent

[glacial kraken]

PermissionsSetupEvent luckperms listen for that?

ok nice works

[fossil sundial]

Yes, LuckPerms listens for that and registers itself. But the event is not fired before the player has a UUID assigned yet

it doesn’t make sense otherwise

[glacial kraken]

ok time to let my friend test the plugin

[fossil sundial]

I can already tell you that this will only stop low-skill players

[glacial kraken]

that bug was gonna be an exploit for my plugin

good thing i found it early

[glacial kraken]

wdym low-skill

[fossil sundial]

the point of this plugin is to hide information about your server

[glacial kraken]

yeah

[fossil sundial]

Well, proxies are terrible at being hidden

[glacial kraken]

uhh it doesn't currently hide the proxy

my plugin would do all it can to make players unable to find plugins

only way left would be guessing

by the way the docs for isActive is not clear, does it check if player is online on a server?

[fossil sundial]

that’s for the channel, tho you really shouldn’t be touching that

[glacial kraken]

i trust that boolean for checking if perms are loaded

hope it goes fine

if this check goes wrong then exploit is made

[fossil sundial]

Since the event should be fired before the player is in the PLAY protocol stage that shouldn’t be an issue

though you are treading in unsupported territory so I can’t tell you

[glacial kraken]

Do i need a check for paper too?

Listening to COMMANDS and TAB_COMPLETE with protocolib

With no checks before perms

Is it fine for paper/spigot

[burnt dragon]

honestly, have you considered just negating the permission for that command and changing the spigot.yml setting to not send command namespaces?

[glacial kraken]

spigot.yml's option is dumb

also no, i do more than just removing plugin:name

good its working

[maiden hawk]

@fossil sundial Hey, how would I make the / completion commands disappear

[fossil sundial]

Brigadier has a predicate requirement function. If that isn’t matched it will not display

That was broken in the past but is now working correctly

[maiden hawk]

So it won't appear even when I type / ?

Will the command just not be there?

[fossil sundial]

they’re not sent in the available commands if the sender predicate you can set isn’t met; that’s essentially it

like try /velocity dump for example

without permissions vs with

[maiden hawk]

To put this in context, I want the commands to not appear when player doesn't have permission to execute them. It works like this normally on bukkit

[maiden hawk]

yes, but the velocity still appears

[fossil sundial]

then you just have to supply the permission as predicate when registering the command, and not check it when the command is executed

[maiden hawk]

oof ok

[fossil sundial]

That’s how brigadier works on vanilla too

[maiden hawk]

@fossil sundial This seems to work, however the root command is still visible.

how would I make that one dissapear?

[maiden hawk]

I am using the List<String> suggest function

And returning an empty list when the sender doesn't have permission

which should I use then?

[bold wharf]

did you set a predicate on the root?

[maiden hawk]

Considering I do not know how, probably not.

[bold wharf]

don't mention

[maiden hawk]

oof, sorry, I have it turned on by default

anyway, any tip on how to do that?

@fossil sundial This is kinda awkward, but how do I set a predicate on root?

[nova radish]

Is @Subscribe(order = PostOrder.EARLY) the eqivalent to @EventHandler(priority = EventPriority.HIGHEST) ?

[maiden hawk]

nope, EARLY is equivalent to LOWEST,

HIGHEST is equivalent to LATEST

[nova radish]

Hmm alright, thanks!

[nova radish]

There is no latest so I'm guessing late.

[maiden hawk]

yup, sorry

[nova radish]

No problem, you helped good enough where I could put the last pieces together, thanks so much

[maiden hawk]

Where would I find that? Here it says that it supports 1.1
https://github.com/Incendo/cloud/tree/master/cloud-minecraft

[burnt dragon]

that's what it says yeh, but it works fine on 3

[maiden hawk]

does it also block players from viewing commands when they do not have permission to run them?

[burnt dragon]

yes

[maiden hawk]

Great

[burnt dragon]

assuming you set the permission on the command

[maiden hawk]

I'm going to switch to it

Thanks!

[burnt dragon]

good choice :p

[maiden hawk]

Of course, is it any fundamentally different to ACF?

[burnt dragon]

i mean, the fundamentals are very similar but there are a lot of differences, some big some small

[maiden hawk]

Okay, gonna read the docs, I hope I won't have much work to migrate from ACF, fortunately I only have like 15 commands.

[burnt dragon]

they have a discord as well if you need support

[maiden hawk]

Perfect, gonna join it, thanks for the info!

[rare osprey]

Is there a easy way to send a Plugin message?

[nova radish]

cloud commandframework is the future!

Regardless, is there anything similiar to getResource or getResourceAsStream for Velocity?

[dull sierra]

Isn't getResourceAsStream just part of a class in general?

[nova radish]

Well, getResourceAsStream is from Bungeecord, getResource is from Bukkit, I was wondering if there is somehting like that in Velocity because all I'm trying to do is implement Velocity support for BanManager

[burnt dragon]

they are part of java

can be obtained from a class or classloader

so MyClass.class.getClassloader().getResourceAsStream("etc")

[nova radish]

Thanks! Still learning Java somewhat, may of skipped past a few sections 😛

[spiral thunder]

Hey,

Is there a way to check if the player was connecting to the proxy in a KickedFromServerEvent?

[burnt dragon]

did you have a look at the javadocs of that event?

there's a kicked from connect property

[nova radish]

Looking at the JavaDocs right now, I don't see any method to get a player class from CommandSource

I would search for this in the Discord, but you know, new Discord thing

[burnt dragon]

instanceof ?

[nova radish]

I don't want to check if the CommandSource is a player- wait would that work?

Okay, i think i confused myself.

[burnt dragon]

command source is an interface that is implemented by things that can be the source of a command

one of those things is the Player object

[nova radish]

Ah okay, so it's basically similiar to CommandSender like in Bungeecord?

That's what I was generally thinking, but I'm also thinking I'm gonna need to rethink this for a bit.

[burnt dragon]

essentially yes

[latent kelp]

Where can I find the resetting of a players information when they disconnect/transfer servers? Specifically resource pack, I can only seem to find the handling of them connecting

[bold wharf]

probs the client does that when it's sent the login packet again

that packet causes the client to reset a good chunk of state

[latent kelp]

loverfella manage to make it so the client doesn't change resource packs when switching between servers

or is that only possible on lilypad?

[bold wharf]

that's possibly on lily and the default behavior on bungee/waterfall

it basically involves a lot of extra crud in order to pull of that way, e.g. rewriting the metadata for entities, etc

[latent kelp]

Bungee doesn't do it either, well not the newer versions at least, so a fork of velocity which does that is very unlikely/would be hard to maintain?

[bold wharf]

bungee doesn't resend the login packet, it basically just makes it look like a dimension switch

no idea what lilypad does, that doesn't seem to have logic for doing the rewriting stuff

but, no reason they couldn't be doing that sorta magic on their own

In part am just theorising on it based upon past knowledge of how some stuff works

[latent kelp]

Yeah well its pretty annoying with the way I've got multi instances setup that when switching between zones you load the texture pack twice, once for leaving and once for joining, its a massive problem tbh

[bold wharf]

if it's what I think it is, velocity has no real control over that

[latent kelp]

so how do you think loverfella get around the loading screens of it?

[bold wharf]

as I said, they won't be using the join packet

[latent kelp]

hmmmm, okay, thanks

[nova radish]

there we go https://i.imgur.com/9U7VgUI.png

Could anyone help me? 😅 

`ProxyServer#getChannelRegistrar().register(() -> "labymod3:main");`

<@&748618676189528155> ?

[scenic grove]

Don't ping mods.

If you need help just wait

[eternal lark]

Unless the help you want is getting punished. 😄

[sleek nacelle]

oh boy free warning

[valid wasp]

You want register(MinecraftChannelIdentifier.create("labymod3", "main"))

[rare osprey]

thank you 😄

[nova radish]

A small price to pay for a faster response time 🤣 /s dont ban me

Is it possible to dispatch commands to the proxy like Bungeecord?

Looked through the Javadocs a bit where I thought it would be, but I don't see anything like that

Found it. commandManager

[nova radish]

Is there anyway to get a command from the commandManager or at least get all the commands registered under the commandManager?

[burnt dragon]

what's the xy?

[coarse topaz]

You can get all of the aliases, and with that you can get the command meta using CommandManager#getCommandMeta(alias)

[nova radish]

Ah okay! Thanks!

[nova radish]

What would be a similar solution to event.setCancelled(true) for PlayerChatEvent?

This whole ChatResult doesn't say what I should be setting the value as

AHAH!

it's PlayerChatEvent.ChatResult.denied()

I'm so smart.

[nova radish]

server = ProxyServer

Oh sorry! I forgot to turn off the ping option.

[coarse topaz]

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

Make sure you’re using 3.0.0

[worldly granite]

how do i go about using the plugin messaging channel

[worldly granite]

i'm trying to port a bungeecord plugin to velocity that fowards a plugin message and saves it

[grizzled rapids]

Where is Velocity Javadocs? I want to disable tab completions completely

I'm having a problem with sendResourcePackOffer... basically I'm sending this in the ServerPostConnectEvent, but when joining a server, the resourcepack prompt appears for a moment but then it seems the server (or client) forcefully close the prompt during the join process - will delaying this method by a second ensure the player is shown the prompt?

[fossil sundial]

Yes. I consider this a bug because I’m still not entirely sure what causes it or how I can prevent it without arbitrarily delaying it

[nova radish]

I am, but, it appears to be not showing for me. But onto more pressing matters, my lovely Velocity plugin doesn't function at all!

[fossil sundial]

Did you try to refresh your dependencies?

[nova radish]

Trying now

Nope. And yes, I checked my pom.xml and it's currently set to 3.0.0, it was previously set to 3.0.1

[fossil sundial]

Any 3.x should have it
Also you sure you didn’t change the version of the annotation processor and forgot to update the api?

I’ve made that mistake too many times to count

[nova radish]

I don't believe so? I just have Velocity as a simple dependency with the type of jar and javadocs :hmm:

[fossil sundial]

You’re using IJ right?

[nova radish]

Intellij?

[fossil sundial]

Yea

[nova radish]

Yep

[lofty tapir]

Ok, thanks

[fossil sundial]

You can check the imported dependency under libraries in the tree on the left

If that’s still on the old version you might have to re-import the maven project

[nova radish]

https://i.imgur.com/5KgnnZq.png

Looks to be just 3.0.0 and a lot of red, I'll reimport real quick

[fossil sundial]

Your classpath/index (cache) is broken

A reimport should fix it

[nova radish]

Alright

https://i.imgur.com/wZnBoeM.png

[fossil sundial]

Do you have an overlapping dependency on the root module?

Or is a dependency overshadowing your imports?

[worldly granite]

ok i got it

how do I use config

I looked at the sponge config but it didn't make much sense to me

so

[nova radish]

Maybe, but it's not my most crucial problem at the moment.

But generally, I think it's fine since my functions accept null from the function, moreover to the more important thing that is preventing me from testing the plugin..

@Plugin(
        id = "banmanager",
        name = "BanManager",
        version = "7.6.0",
        url = "https://banmanagement.com",
        description = "A suite of moderation plugins & apps for Minecraft servers",
        authors = {
        "confuser"
        }
)
public class BMVelocityPlugin {
  @Getter
  private BanManagerPlugin plugin;
  @Getter

  public void onProxyInitialization(ProxyInitializeEvent event) {
    onEnable();
  }

  }
}```

Error: https://paste.gg/p/anonymous/0751adaddd83480e9fdf31f30217a8ff

[fossil sundial]

Velocity uses log4j and you can’t inject a logger type from a library velocity doesn’t have

Well that is unless you provide it appropriately

[nova radish]

Epic, thank you

[tough olive]

is it possible to bind in ipv4 and ipv6 ?

[fossil sundial]

Velocity does that by default if the v4 and v6 network stack is available with your configuration and JVM/system
Though the minecraft client doesn’t support it without modifications

[tough olive]

yes before 1.9 for client

because this netty version before does not support ipv6

[nova radish]

Odd, I changed my imports to import log4j but it's still giving a similar error: https://paste.gg/p/anonymous/066c11cbcb444a3cba90634e7dbe3986

My apologies, left the ping on

[jolly sandal]

Hi guys Im trying to open a book to a player but it isnt shown here is my code:

this.proxy.getServer().getScheduler().buildTask(this.proxy, () -> {
            player.openBook(Book.builder()
                    .title(Component.text("News"))
                    .author(Component.text("Pseudow"))
                    .addPage(Component.text("§c§lNOUVEAUTES: \n§cSoon").asComponent())
                    .build());
        }).delay(1500, TimeUnit.MILLISECONDS).schedule();

It is fired in the PostLoginEvent

[rich hawk]

afaik you can’t do books on velocity

[jolly sandal]

what? why are they inside so?

[rich hawk]

From adventure

[jolly sandal]

what?

[fossil sundial]

The text-library velocity uses has that feature, but Velocity doesn’t provide it as a feature. I still think it should be removed from the adventure api proper or moved to a separate module

[jolly sandal]

oh okay

thanks

[fossil sundial]

The reason this isn’t a feature is that it would require velocity to have a full implementation for the player inventory

which isn’t good for performance and isn’t really a good idea for a proxy which doesn’t track states

[manic pumice]

Heyo, did you get a chance to look in to this?

[glacial kraken]

can i use color codes (like &c) in log messages?

[ashen pawn]

Yes but it's not recommended. You would have to construct the messages as a component and serialize them as legacy text. Just don't bother with colored output.

[burnt dragon]

also, don't put legacy formatting codes inside components

[glacial kraken]

what is the event when player joins the proxy

[agile ore]

Pre/PostLoginEvent

[glacial kraken]

can i send messages here?

[agile ore]

should be fine in the post login event

pre probably not since the player isn't actually logged in yet

[glacial kraken]

ok thx

[glacial kraken]

getClass().getClassLoader().getResourceAsStream("version-config.json") NPE

i just need to read a resource bruh

[proper gulch]

Hey, can I use plugin messaging channel on a spigot plugin when the proxy is running on velocity?

[fossil sundial]

You sure your path is correct?

[fossil sundial]

Depends on what you mean by that
Velocity supports both bungeecord:main (and its commands) as well as custom plugin channels (which require a plugin on velocity to function obviously)

[glacial kraken]

umm yes its in the resources in src

and i see it in jar

[proper gulch]

This, https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/

Thats possible right?

Without any velocity things in my spigot plugin

[fossil sundial]

Yes but I’m currently in dialogue with people from spigotmc about if this is a bug in bungeecord which should be fixed instead

[manic pumice]

Cool, when I first found the 'feature' in bungeecord I thought it was a tad weird that you got an almost incomplete response but at least it was a response.
Is there any other native way to see if a server exists from a plugin? Or should I look for alternate methods than a velocity plugin channel message?

[fossil sundial]

Bungeecord has the GetServers subchannel command which id much recommend over your approach

GetServer should also work; the response should be empty on that one

Though I’m not quite sure in that case

[manic pumice]

I will switch out some logic and use one of those then. I can always store the last time I got a PlayerCount response back from a server and ping off a GetServer if its been a long period to check if it still exists (that's if the GetServer responds I'll shout if not). Thanks again for looking in to it.

[glacial kraken]

how can i run an async task

how to auto make links clickable in component?

[burnt dragon]

there's no way to do it automatically, you'll have to use the replacement system matching a url regex

or just construct the component with correct click events in places

[verbal rain]

hey so
trying to add velocity as a dependency and intellij is angy
this is the correct dependency right?

  <dependency>
        <groupId>com.velocitypowered</groupId>
        <artifactId>velocity-api</artifactId>
        <version>1.0.0-SNAPSHOT</version>
        <scope>provided</scope>
  </dependency>```

[fossil sundial]

We are at 3.1.0 currently; you seem to have stumbled upon the old documentation which has long since been abandoned

[verbal rain]

ah that would be the trouble then

thanks m8

[median vessel]

How do you kick someone from the network programmatically?

(from a paper plugin, not a velocity plugin)

[harsh saddle]

When will velocity support forge 1.13>?

[fossil sundial]

Using the bungee plugin messaging channel; Assuming you didn’t disable it you can use that to kick a player from the proxy with a plugin message.
We didn’t bother reinventing the wheel and this way we stay somewhat compatible to downstream plugins that just need basic proxy functionality.

You can read about that here
https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/#kickplayer

[fossil sundial]

Discord decided to be dumb and didn’t process that as a reply, see ^

[agile ore]

?

[agile ore]

Hello

what's new with velocity 4.0.0 api?

[analog dew]

Velocity 4.x barely exists right now

[agile ore]

oh right

so I should just go for 3.1.0?

[analog dew]

Yes

[agile ore]

okay 😄

[slow terrace]

Just wondering is there anyway to send a message between a server and the proxy without using a player? or does velocity have its onw messaging channel i can access within a pluign)

[burnt dragon]

nope, you have to send it through a player

[slow terrace]

ok

[glacial kraken]

You can just encrypt the message if u don't want them to see, i think

[quaint canopy]

Is it possible, to get the ClassLoader, which loaded the plugin?
It's possible in PaperSpigot and I need this, to use the ServiceLoader

[glacial kraken]

Yes u can getClass().getClassLoader()

[paper geyser]

is there a way like bungeecord to be able to talk to the proxy via server side. I'm asking as i want to be able to send players cross server on server-side

[fossil sundial]

the bungeecord or bungeecord:main plugin channel is supported on velocity. If you didn’t disable it in the velocity.toml it should behave the exact same way as on bungeecord

[teal sand]

Hi I have a question regarding velocity.
Does Velocity natively support the bedrock protocol?

[burnt dragon]

no

[paper geyser]

okay thanks

[tender spruce]

You need geyser mc and floodgate

[median vessel]

Follow-up to my earlier question - is there a way to test if the BungeeCord plugin channel is available? I basically want it to do a proxy kick if it is, and a server kick if not so I need to know if its available

[teal sand]

Yes i know, but i need only bedrock (no java edition bridge)

[tender spruce]

Ah

[agile ore]

Don’t think so, you’d have to send a message and see if you get a response in X seconds, otherwise kick them on the paper server

Most plugins seem to handle this with a config option

[harsh saddle]

It seems like lightfall did

Im purely using velocity for 1.7 support

[ancient cosmos]

Is there any way to not have certain servers included in the /server command?

[agile ore]

^

[bold wharf]

No, basically, you'd need to implement your own /server command with its own stuff and implement your own restrictions, etc

[tender spruce]

how can you run a velocity server in a dev environment?

[maiden hawk]

If you're running IntelliJ you can just add it as a JAR Application in Run/Debug Configurations

At least, that's how I do it

[trim forge]

Any way to handle when a player joins from an outdated client? Velocity poos itself when that happens

[tender spruce]

Yeah that’s what I ended up doing. Is there a way I can make it automatically use the new build without having to manually move the plug-in jar every time?

[maiden hawk]

Depends on the build system

if you use maven

you can do it the same way as I do

and use the maven jar plugin

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <version>2.3.1</version>
                <configuration>
                    <outputDirectory>test/plugins</outputDirectory>
                </configuration>
            </plugin>

[tender spruce]

Is there a similar tool for gradle?

[maiden hawk]

i have no idea

probably google something like

gradle specify jar location

or smth like that

[tender spruce]

Okay lit thank you

[maiden hawk]

np

[fossil sundial]

Outdated as in? Velocity supports 1.7-1.18.1 currently and there are events for legacy handshakes

[steady kettle]

Does ChatResult#message not support coloring? Because I’m having an issue with it

[trim forge]

Sorry I was just being slow

One issue I can't seem to figure out though is litebans not working properly on velocity. Bukkit seems to override any litebans commands, and there is no way to stop it doing that. I'd have presumed that the proxy would handle commands first, but and commands in litebans that are also on a bukkit instance (e.g. /ban) is used as the bukkit command rather than the velocity one. Any ideas? TIA

[vestal prawn]

You misconfigured Litebans then

Normally litebans on bukkit override /ban of bukkit

[trim forge]

That'll be a yikes

Let me go take another look, apologies if I've just been stupid

[vestal prawn]

But the override thing of bukkit has nothing to do with the proxy

[trim forge]

Oh my goodness I've had a MASSIVE yikes

Any chance we can just delete these messages and forget about it?

[vestal prawn]

i already screenshot the messages, these messages will stay forever in our minds

@trim forge did you encounter issue with Litebans on Velocity ? Because it's pretty new and i want to switch to Velocity

[trim forge]

No issues apart from ones that I made myself

[tribal adder]

Hi! I'm trying to create a plugin that removes commands from the / command menu.
Bukkit has an event called PlayerCommandSendEvent to get the list and remove commands from it.
The only thing I can find in the velocity javadocs is TabCompleteEvent, but the description says it's below 1.12.2 and it doesn't exist in the maven dependency (intellij intellisense cannot import it).
Is there an event for it, or is there another way to remove commands from the menu?

[craggy pecan]

Use https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/event/command/PlayerAvailableCommandsEvent.html

Although you should use permissions to remove suggestions, your idea is a really ugly hack

[tribal adder]

Thanks for your help!

[tender spruce]

how do you create a listener to listen for messages on a MinecraftChannelIdentifier?

[trim forge]

I'm trying to make a method that falls players back to a hub server if a main server goes offline, as for some reason velocity doesn't always do that, but the KickedFromServerEvent isn't catching it - any ideas what's best to do? Thanks

[tribal adder]

In velocity, is there a way to open inventory menus for players, for example a custom /server command with an inventory to select a server?

[fossil sundial]

Sometimes the player is in a state you cant recover from if the server looses connection; That does happen; But I am not following on your question here

[fossil sundial]

Generally these kinds of things should be handled by the server as inventory and player-state-tracking isnt done by velocity

[tribal adder]

Ok, thanks for your response!

[fossil sundial]

https://gist.github.com/Xernium/95c9262c5f70b8791557861bbc09be1b see this for an example in both sending and receiving messages

how to delete the log of the initial disconnected connection, it spams that when my anti-bot plugin denied the result from preloginevent

[agile ore]

Hey, is there a velocity plugin messaging system? I've found this - https://jd.velocitypowered.com/3.0.0/com/velocitypowered/api/proxy/messages/package-summary.html - but not sure how to accessi t from Paper

Our Bungee Messaging plugins which worked on latest BungeeCord aren't working on latest Velocity, so just trying to fix it. Using the channel BungeeCord

In velocity.toml, we've set player-information-forwarding to legacy in order to support it, too.
In the [advanced] section we've also set bungee-plugin-message-channel = true

Maybe we're missing something?

[fossil sundial]

No; that should just be it. What’s your game version?

[agile ore]

1.17.1

[fossil sundial]

Not possible without a custom log filter

[fossil sundial]

The channel for connections using 1.13 and above is bungeecord:main

[agile ore]

Latest BungeeCord supports BungeeCord but Velocity only supports bungeecord:main?

I'll try swap all chan names to bungeecord:main, tyty

[fossil sundial]

This is md_5 breaking game design again if true

1.13+ requires the namespaced:key format for channels

Which is why just BungeeCord shouldn’t work

[agile ore]

Alright thanks, I've encountered new errors but moving to #paper-dev for that 😄

[agile ore]

Hey, does velocity account for this? https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/plugin/messaging/StandardMessenger.java#485

I've changed my code now so that there's an outgoing channel - "BungeeCord" (as this method will make it bungeecord:main) and an incoming channel - bungeecord:main (as this method will make it "BungeeCord" for some reason)

[burnt dragon]

honestly that is a genuinely terrible method that needs to be split into incoming/outgoing

[agile ore]

I mean it's deprecated. It's still just used.... alot

I'm just going to fuck it and set up a Velocity plugin/channel to handle forwarding messages to servers lol

[fossil sundial]

No it doesnt; and nothing should account for that, because the result of this method is wrong either way

[agile ore]

Idk where my problems lie but for now I'm just going to blame that lol. Thanks for all the help

[fossil sundial]

are you using ViaVersion or ProtocolSupport?

[fossil sundial]

no I meant on the proxy;

[agile ore]

yee that's the proxy

[fossil sundial]

my brain is fried; server
