does in velocity something changed with favicon for 1.19 clients?

bronze yoke
#

not necessarily 1.19 specific, had it on older versions too

#

don’t know what causes it tho

agile ore
#

I'm trying to send a plugin message to a velocity proxy from papermc. This is how I do it:

target.sendPluginMessage(BukkitServerCore.instance, "megavex:autoban", byteArrayOf())

And this is how I am listening for it:

@Subscribe
fun onPluginMessage(event: PluginMessageEvent) {
  println("Plugin message received: $event")
}

However I don't seem to receive the message. What am I doing wrong?

#

I also registered the channel on papermc like this:

server.messenger.registerOutgoingPluginChannel(this, "megavex:autoban")
#

The listener is definitelly registered, I tested that.

languid rover
#

have you registered the channels?

agile ore
#

I only registered it on papermc

#

not on velocity

#

do I have to do that?

languid rover
#

on velocity you should also have something like this.server.getChannelRegistrar().register(ChannelIdentifier);

agile ore
#

yep, that worked

languid rover
#

nice

Hey, how do you cancel an event?

#

with the player chat event

is there a services manager like Spigot where you can register your services?

is velocity polymer still roughly on track to release at 2023 Q1 or is it likely it’ll release later?

coarse topaz
#

Potentially later than that. Tux recently moved and switched jobs so he has been quite busy

wary tiger
#

Velocity polymer, I am sure, will require much more time to develop than between now and March 2023

yeah I’m aware now given that tux has had more to work with since I last heard a rough eta

how do I use com.velocitypowered.api.proxy.messages?
(I can't find any guides on youtube)
I'm reading the docs and this is all I figure out
this.server.getChannelRegistrar().register(MinecraftChannelIdentifier.from("connect_requests"));
how do I tell it what to do when it recives a pluginMessage?

#

Thats from Velocity

#

No request is sent or detected on Spigot.

fossil sundial
grave sierra
fossil sundial
#

I mean where was the pack sent from originally

#

If it was the proxy then this is absolutely working as intended

grave sierra
#

Its proxy

fossil sundial
#

Yea then it’s working as intended

#

The proxy sending the request on previously was a bug

grave sierra
#

My problem is that it is not sending the status to the backendserver.

oblique haven
#

the proxy purposefully doesn't pass status back if the origin was the proxy since the backend isn't the one "handling" that pack - you're free to use plugin messaging to achieve this though with custom channels, shouldn't be too hard

grave sierra
#

I can do that before.

I check if the player has properly loaded the resource pack with the spigot ResourcePackStatus event from the lobby server.

It was working in January-February.

oblique haven
#

what you're seeing is intended - what was happening before was not intended if it was passing it back

#

I believe there was an issue with original origin or something which Five fixed in one of the prior patches which led to that PR

grave sierra
#

But after these dates, this is the only action taken on the issue.

oblique haven
#

this isn't an issue

#

it's intended behavior

grave sierra
#

I mean yes

#

Then what's causing it to work beforehand?

oblique haven
#

a bug

#

non-intended behavior

grave sierra
#

Could Spigot detect that the player's resource pack was loaded due to the bug?

oblique haven
#

you're saying spigot isn't sending the pack

#

the proxy is

grave sierra
#

I want to explain my problem from the beginning.

#

When I sent the resource pack over the proxy in January-February, I could detect the player's resource pack from the spigot servers on the backendserver with the "ResourcePackStatus event". But now I can't do that.

oblique haven
#

right

grave sierra
#

I've been looking for what caused this all along. I can't understand why.

I was not using the message channel before.

Just a resource pack plugin via Velocity and an event listener via spigot server. This much.

oblique haven
#

Right - that was unintended behavior and has since been fixed

grave sierra
oblique haven
#

just send a plugin message

#

having a random resource pack ack to the spigot server about status makes no sense outside of your particular scenario

#

if spigot didn't send a resource pack - it's not expecting a response, so it makes absolutely no sense to send it one

#

if you want to imitate one you're free to do so with plugin messaging - but that's imo probably the best way to handle it

grave sierra
#

Understood.

Hello everyone, can anyone write me a line with the code for teleporting to the server at certain coordinates?

burnt dragon
#

no, this is for help with development not comissioning people to do work for you

#

Not without a plugin on the server itself, no

agile ore
#

Is there a way I can get a list of running backend servers? Basically I want to check if the player is allowed to join a specific backend server on a ServerPreConnectEven, if not send player to the first fallback server that they have access to.

#

Is there a better documentation on velocity & its velocity-plugin.json ?

#

Because I am finding lots of conflicting information

#

I cannot get a velocity-plugin.json to generate

# 
dependencies {
    annotationProcessor("com.velocitypowered:velocity-api:3.0.1")
    compileOnly("com.velocitypowered:velocity-api:3.0.1")
}
``` Should be this simple; why not?
coarse topaz
#

Do you have the @Plugin annotation in your main class

south ermine
#

I needed to use kapt as the annotation processor due to kotlin source file

coarse topaz
#

Ah yes, that'll do it

south ermine
#

Fun fact, for some reason plugin id cannot have uppercase

coarse topaz
#

That is correct

south ermine
#

Not in the annotation exception

#

Not in the docs

coarse topaz
#

However, I feel that shouldn't completely stop the plugin from starting imo

south ermine
#

It prevents it from compiling

coarse topaz
#

It would be much cleaner if we just threw an error and allowed the plugin to load

#

well, yes

#

But, I do not feel that it should

#

Ideally, we should just ignore the casing of the letters and automatically format the string

south ermine
#

Well, I guess my only recommendations are to add such things to the documentation (usage of kapt for kotlin sources, lowercase plugin id)

#

Thanks for the help though

valid gazelle
#

Would it be possible to make a compiler error/warning for that because that would make more sense

coarse topaz
#

Well, we can do two things simultaneously in theory

#

Auto lowercase plugin id's, and print a better message

#

Perhaps something like this

unknown.png
opaque escarp
# coarse topaz Auto lowercase plugin id's, and print a better message

Printing a message with the invalid id entered is a good idea, but converting the invalid id to lowercase may cause some unwanted problems. For example, if you want to depend on another plugin and it is opensource, you can look at the main class and copy the id to use it in the dependencies of the @Plugin annotation, but in case the id is invalid the plugin will not be able to depend correctly on the other plugin

coarse topaz
#

Perhaps we should apply the same logic to the dependency then

maiden hawk
analog dew
#

kapt being needed to run annotation processors on Kotlin code isn't specific to Velocity, that's just general Kotlin knowledge

#

I don't think it's particularly important for the Velocity docs to document how to use Kotlin

#

Are you we able to hide disconnect messages when we disconnect a player with event.setResult(ResultedEvent.ComponentResult.denied(message));?

As if they are formatted pretty they take up a bit of console space

How would I go about sending kicked players to a predefined server? For example, if I join a server and get a forge mod rejection (or I get kicked for any other reason) I want the players to be sent to the lobby again

#

I know on bungee I somehow managed to not even connect to a server if the join event was cancelled so I would just remain on the lobby if I got kicked instantly

burnt dragon
#

you can listen to the kicked event and set a redirection iirc

copper crown
#

getServer should be the server you're kicked from then, right?

Hello, I have an issue with PlayerAvailableCommandsEvent event. I am trying to prevent tab-autocomplete ONLY for proxy commands, but this event includes both proxy and server commands. How can I distinguish these two type of commands?

burnt dragon
#

you can check if the command exists in the velocity command manager

#

it has a method to get a list of aliases

#

but also, consider not removing tab completion as it just hurts accessibility for no gain

south shadow
#

I am just trying to prevent players to see those commands

burnt dragon
#

use a permissions plugin

south shadow
#

I am developing a plugin, I already have spigot and waterfall compatibility, but I want velocity too

south shadow
burnt dragon
#

that doesn't have anything to do with not using a permissions plugin but whatevs

south shadow
#

even with a permission plugin, commands will appear in the tab completion

#

that's why there are hundreds of anti tab completion plugins on SpigotMC

#

I am new to velocity, I don't know much about it, maybe velocity already blocks all commands on tab completion

#

but that doesn't happen on bungeecord or waterfall.

bold wharf
#

Plugins which properly define their stuff will not show up in tab completion

#

Like, that 100% happens on waterfall

fossil sundial

^ Plugins just suck at using it, but the feature is literally there and has existed for a looooong time

Also, i got chat registry passthrough working, all of my checks for equality came back true, and chat actually works again! now just for eveeeerything else, lol

ruby spear
bold wharf
#

Well, that's part 1, gotta work on all the business which will use that

#

i.e. registering custom types, etc

#

Think I'm going to wait on seeing what adventure does before I actually bother with the API side of stuff, idk what all they intend to cover, but, want to at least get the business logic needed in place for it

ruby spear
#

do chat events work any differently with the signed messages

#

I'm not sure what to change on my end to update to velocity 1.19

bold wharf
#

Well, the signed message will need to be passed around, part of what I'm waiting on adventure for

#

Honestly, I ain't done much with velocites API, or the codebase, so this is all pretty much a new territory for me, already had a few fights with checkstyle

ruby spear
#

what are other servers doing using velocity with 1.19? embracing the jank?

bold wharf
#

I mean, thus far it works fine, I don't think anything supports the signed message stuff though

ruby spear
#

is there a way to just disable signed messages

bold wharf
#

pretend that every message is sent by the server

ruby spear
#

welp

solid ivy
#

Technically you can create custom message type

#

That only displays players name

#

Then just use display name for message

#

Through it's harder on proxies

fossil sundial
solid ivy
#

It will

#

Since displayname is fully controlled by server

#

And client never signs it

#

Just content part of message

#

Which doesn't even need to be visible

fossil sundial
#

Turn off the chat decorator preview packets and see if it still works

I'm sure newlines were broken on chat

It works in chat in 1.8, but not in 1.7.

obtuse locust
#

why I can not get resource from plugin folder on velocity? resourceAsStream is ok but result is empty

unknown.png
bold wharf
#

Because you're calling it on the classloader

#

the classloader is, well, looking at the jar file

#

if you want a file off the disk, create a reference for that

obtuse locust
bold wharf
#

then open it as a jar file

#

a folder is not a resource

obtuse locust
bold wharf
#

google

#

think you could do it from the code protection thing or something

obtuse locust
obtuse locust
bold wharf
#

Yea, stuff like that is none reliable

#

guessing that your "working" test was ran from the IDE where the classloader is often pointing towards a folder

obtuse locust

maybe..

velcity has google libs

# 
List<ClassPath.ClassInfo> classes = new ArrayList<>();

for (ClassPath.ClassInfo info : ClassPath.from(LiteProxyManager.class.getClassLoader()).getTopLevelClasses()) {
    if (info.getPackageName().startsWith("dev.rollczi")) {
        classes.add(info);
    }
}
#

works

#

or

Set<ClassPath.ClassInfo> classes = ClassPath.from(LiteProxyManager.class.getClassLoader()).getTopLevelClassesRecursive("dev.rollczi");

could you theoretically use signed messages with a custom chat formatter?

To clarify... Velocity 3.0.0 (in its first release) and Velocity 1.1.x are the same, except that Velocity 3.0.0 removes text, updates guice and starts using Java 11

now I am confused as fuck

#

why did velocity 3 come before 2, but after 1?

#

The 1.x series couldn't continue without breaking changes, but 2.x was already assigned at the time

IIRC, semantic versioning allows for breaking changes at the minor version, right?

Hi all!
I need help getting a PluginMessage on the Paper Server.
So I send a PluginMessage to a chat event from my proxy using: sendExampleMessage(e.getPlayer(), "123");
The sendExampleMessage() method was taken from https://gist.github.com/Xernium/95c9262c5f70b8791557861bbc09be1b.
On the Paper server, the handler was taken from https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/

On my Paper server, I register a channel: this.getServer().getMessenger().registerIncomingPluginChannel(this, "mychannel:main", this);
And in the onPluginMessageReceived() method I check if it belongs to my channel.
But tests have shown that even the onPluginMessageReceived() method itself is not called, that is, I'm just trying to display in the logger that a message has arrived without any checks.
But nothing happens, I can't figure out why it doesn't work. From the server side, I can send a message and it will come to the proxy.

I can't figure out if I'm sending it somehow wrong or it's not accepted on the server.

I am using Velocity 3.1.2-153
and Paper 1.19-17

You’re thinking wrong. The destination you want to send it too from the proxy is not the player. You want to send it to the server; the channel message sink is the ServerConnection if you want to send it to the server

Anyone have a simple example on how to use plugin messaging channels?

opaque escarp
pale aspen
#

How can I make an API for a Velocity plugin that plugins on sub servers can use?

sour current
#

You'd need to use something like plugin messaging or redis so that the plugins can talk to eachother

pale aspen
#

Is there any resources I can read on plugin messaging?

#

I'm making a friends plugin in Velocity and I basically want to make an API that gets the friends of a specific person

sour current
#

See the message that 4drian3d replied to above yours, its the spigot page on the bungee channel which shows how to use it

pale aspen
knotty mica
#

Yes

sour current
#

That's possible I think, though it'd be better to use something like mysql

pale aspen
#

How would that make things easier?

sour current
#

If it's for an api for other plugins to use then probably not, nvm that

pale aspen
#

I still don't understand how I'm supposed to be sending a list of data from the Velocity plugin to the server

#

What I'm getting is that I have to register a channel using the Velocity plugin

proxy.getChannelRegistrar().register(someChannel);

Then send some data

sendExampleMessage(player.server, "something");

In my Paper plugin I would register a plugin channel and an event for it. But I don't see how I can make an API with this

#

I would have to listen and deserialize the data for every plugin

fossil sundial
#

You can’t share a classspace so this is more or less one of the only ways to move data

fossil sundial
#

If it were easier then Minecraft wouldn’t have the networking code it does currently

bold wharf
#

at the end of the day, they're two isolated program spaces

#

anything you do between the two is gonna involve some form of communication

pale aspen
#

That's all fine and good, but I am trying to make an API. It seems I can't

bold wharf
#

Well, you kinda can't

#

at least, any API you make is gonna rely on communicating over the network

#

Like, if you want reliable connections and stuff and to have an "API", you'd generally be better off writing some REST API and wrapping API around that

#

but, then ofc, everything is still network IO

magic forum
#

I'm making an API for Ambassdor

#

So people can create plugins that interact with the forge handshaking process

#

If they want

#

This will be the most used method I think

unknown.png
#

It does all the hard work for you

#

It uses my custom downloading mechanism to download the handshake packets from the forge server

#

And stores them in simple byte arrays that you can send to the client directly using Velocity API

#

I'm gonna create a way for plugins take over the handshaking process and just use Ambassador as library. If they doesn't, Ambassador is gonna default to it's own handshake handler

#

Basically, I'm doing a full rewrite right now

gloomy junco
#

Guys, I know that in order to successfully receive the PluginMessage you need at least 1 person on the server, but can I bypass this system to always receive the PluginMessage even if there are no players on the server?

bold wharf
#

No

#

the entire thing relies on hijacking a players connection to send it over

#

No player to hijack, no connection to send data over

#

best you can do is rely on some other solution, pubsub, sockets, etc

gloomy junco
#

I'm understood, thank you

lilac elbow
#

Is there an event that fires when a server connects to the proxy?

oblique haven
#

Players connect to the proxy and the proxy connects to the server on behalf of the player

lilac elbow
#

Would this work or does it need to be sent from a player

oblique haven
lilac elbow
#

Why can you even send it from the server then

oblique haven
lilac elbow
#

So that will work?

#

I just need to send an alert the the plugin running on the proxy then send info back

oblique haven
#

Yep

lilac elbow
#

What if there isn't? will it wait until a player is?

oblique haven
#

Could test it

nova sparrow
#

Plugin messaging requires a player to be online for it to work?

agile ore
nova sparrow
agile ore
nova sparrow
#

I suppose so

#

Better than relying on a player to be online

#

Can think of other solutions tbh

agile ore
#

What are you trying to achieve?

nova sparrow
#

Oh me, nothing

#

I've just never actually used plugin messaging so I was curious

lilac elbow
#

Can someone explain redis to me

#

I always thought it was just another version of mysql

#

Is it not?

valid gazelle
#

its more meant for temporary data

#

it's an in-memory data store

lilac elbow
#

I have a list of players, I need to have the list on proxy side and be able to access it from each server. Right now I was planning on everytime something gets added to the list, send a message to the server and replicate the list there, is there a better way?

valid gazelle
#

yeah redis sounds like the right tool for that

#

i dont really know the specifics that well so i cant give much more advice though

lilac elbow
#

Do you know if sending plugin messages is secure or can clients access it

valid gazelle
#

idk, might have to ask someone else

lilac elbow
#

Because i'm sending database information

valid gazelle
#

yeah i would say that probably makes more sense to go over redis because it's not player specific right

lilac elbow
#

Yeah but thats the other thing

#

Its a bungee network so there will be a lot of servers, and I dont want to have to manually enter the server connection string for each one, so i was going to have it on the main, when the server boots up send a connection ping to the proxy then the proxy responds with the database information and the plugin saves it

valid gazelle
#

is there a way you could pass the credentials as an environment variable, adn then read that variable in your plugin?

lilac elbow
#

Do rented dedicated servers usually allow you too do that?

lilac elbow
#

This look right? isnt sending message to bungee

unknown.png
#

For redis do you need to host a server? i'm looking at https://www.tutorialspoint.com/redis/redis_java.htm will Jedis jedis = new Jedis("localhost"); just run it on the server the bungee is on?

Redis - Java

Redis - Java, Before you start using Redis in your Java programs, you need to make sure that you have Redis Java driver and Java set up on the machine. You can check our Java

valid gazelle
#

i think you have to run redis separately

lilac elbow
#

Yea redis wont work for me because it needs to know when its being called

valid gazelle
#

wdym

nova sparrow
lilac elbow
#

That sounds stressful for the server

nova sparrow
#

do it on another thread every so often

#

its not a good idea but

#

are you just trying to communicate stuff between a front end and backend

lilac elbow
#

Every so often wouldnt work either that ruins the point of needing to know when its called

lilac elbow
nova sparrow
#

I was thinking earlier could you use a http server?

lilac elbow
#

Like if I have a ban command on the server, do the command there, send the info to the proxy, then send the ban info to all servers

nova sparrow
#

on another thread possibly

lilac elbow
#

Which is what im trying to avoiid

#

And does http have an event system with packets?

nova sparrow
#

I mean you can post to a server

lilac elbow
#

Yea at that point I would just create a server from scratch

nova sparrow
#

lmao

#

i mean it is an option

lilac elbow
#

^ im being serious with that I think it would handle data better

nova sparrow
#

I mean thats a fairly big task

lilac elbow
#

I want to see if there is a way to do it directly with bungee and spigot first

nova sparrow
#

You could just fork velocity and add what you need into it

lilac elbow
#

I would also need to fork paper then

#

Which again would just be making a server

nova sparrow
#

Or make a plugin for front and back end

lilac elbow
#

Still would need a server to communicate with each other

nova sparrow
#

And in that plugin make an event fire when you receive a post

#

Yeah

lilac elbow
#

What would be the point for that

#

Thats just exactly what im trying to do already but just with extra plugins for no reason

nova sparrow
#

Then build it into one plugin 🤷‍♂️

#

Its an option

#

Might not be what you want but if redis doesnt work and you can think of anything else

lilac elbow
#

That wouldnt work...

#

You cant communicate directly between bungee and spigot

#

so it cant be one plugin

slate siren
#

well

#

you could have two packages that compile into one jar

#

and have it connect via databases to communicate information

nova sparrow
slate siren
#

not even actual data just booleans etc

nova sparrow
#

sql messaging?

slate siren
#

yeah

nova sparrow
#

yeah thats good

slate siren
#

that’s what i was getting at

nova sparrow
#

used that before

lilac elbow
nova sparrow
#

but i think he'd run into the same problem

lilac elbow
#

Like a spigot and bungee version in 1 jar?

nova sparrow
#

yeah

lilac elbow
#

I know that, but what would that do

nova sparrow
#

Well it would mean you're only making one plugin technically

lilac elbow
#

Depends on what kind of event you want to gauge how feasible any of this is

You can’t get an awaiting event to work right over redis

But the same is true with plugin messaging

Velocity fires events for all resource packs and resource pack status to the api.
The api also exposes where the pack originated from; and if the proxy interferes with the pack it also saves where it was from originally
But in essence:
If the backend sends a pack then the backend will always get a response
If the proxy sends a pack then the backend will never get a response because that would constitute an illegal protocol state

You have to understand that the feature is niche at most, given 1. most servers don't use forced hosts, and 2. even less use it in conjunction with exotic ping passthrough configurations

That 3 lines of code estimate doesn't take into account docs and further confusion when using forced hosts

SRV records do have some caveats

#

I mean, web servers generally run on a different port, so often just host the web server on the same box, or, setup a web server which just redirects to the correct place

SRV sometimes can randomly fail for no reason, which is fun

tho, I've only seen that happen a couple times over the past few months, so

#

weird, why would that happen with srv and not other dns lookups either

#

tbqh, SRV records are somewhat niche

lucid halo

probably bad caching cannot store SRV

and that may incur a longer round trip than A or AAAA

This override here is dum

#

(at least imho)

  1. this is the cause of the <> in messages

  1. adventure defaults that to use the SYSTEM message type, which WOULD be the correct behavior for literally every single usage within the proxy itself, however, I am somewhat iffy on changing this from default
#

@fossil sundial if you happen to be around, thoughts?

fossil sundial
# median ridge Is there any way to intercept messages received through the `BungeeCord` channel...

Why would you need to do that? If you make your own custom plugin you’re expected to use your own namespace:key identifier.
I digress, yes it is possible to do; If you disable the bungee messaging channel in the velocity config then the proxy itself won’t respond to it anymore and plugins can use it. If you need to use a subchannel of bungee you also need to implement the other functionality of the bungee channel to keep it working

Would like some feedback on whether this maven configuration would work or not:
https://github.com/Andre601/AdvancedServerList/commit/67aab526253f82da8afaa0479589de185da07512

My goal is to have stuff such as configurate and Adventure shaded into the core, so that I can then relocate them if needed for the other modules.

Like:

  • On BungeeCord, shade and relocate both into the resource
  • On Velocity, only shade and relocate Configurate (Can't even remember if that is needed...)

If there are any other recommendations to make the jar files both less bloated and functional with BungeeCord and Velocity lmk (Also, to be clear: The jars will be separate from each other. There won't be a universal jar for both proxy types)

if they're separate jars then you can do what you want, keep as much stuff in a commons module as you can and yay

    e.getPlayer().sendPluginMessage(channel, data);

#

i looked at source code, and PostLoginEvent is fired in "game state" after login is finished, so it should be fine to send pluginMessage in this event

I don't see where such a check exists?

      }
      System.out.println(String.format("Packet: %s",packet.getChannel()));
      serverConn.ensureConnected().write(packet.retain());
    }
    return true;
  }

inside InitialConnectSessionHandler

fossil sundial
#

mcconn.ensureConnected()

#

Is in the abstract super class

fossil sundial
fickle grail
#

hmm?

bold wharf
#

I mean, I see that there exists logic for the connection to the server

#

but not for the player itself

fickle grail
#

So I looked inside AuthSessionHandler, in line 141 you change state to Play, fire LoginEvent
then switch Handler to InitialConnectSessionHandler and fire PostLoginEvent, so all logic is handled by InitialConnectSessionHandler, am I correct? I started using velocity yesterday so i could make some mistakes.

#

And of course, if sending pluginMessage will be allowed in InitialConnectSessionHandler, some logic needs to be copied from ClientPlaySessionHandler (like firing PluginMessageEvent) 😄

fossil sundial
#

Again I see how this issue could arise. Open an issue on GitHub and we will look into it soon.
Besides that- which versions are you coding this for? On 1.13 and newer there’s a better solution

fickle grail
#

1.8 as a base, but with ViaVersion

fossil sundial
#

So you want to interact with a client mod?

fickle grail
#

yep, i need to send as soon as possible some data with PluginMessage and wait for response

fossil sundial
#

just before you get your hopes up

#

even if we fix it

#

some versions will not be able to respond correctly before the client is first initialized

#

(aka has joined the first server successfully)

yea, i know but this mod only works on 1.8, so i know it will work, beside that i already "hardcoded" fix and tested it

@fossil sundial is the modern forwarding secret able to be provided by the system (sys prop/env var)? We have an issue where our secrets are defined at a system level so pushing it into a file during runtime makes no sense - it would be nice if we could securely push it into the environment under a hidden environment property, mainly for security

#

Putting it in the file space opens up a potential security issue for our users and I want to make sure we’re not falling into that. For now our unstable latest uses a legacy configuration to surpass this.

otherwise it just passes through silently, but, if you want the commands to exist on the server for plugins to abuse, etc, you'd need a server plugin

cloud iron
#

I see, thanks! So what would the server plugin contain? I'm guessing it's not simply including the command in the plugin.yml

bold wharf
#

well, you'd need to have some way to communicate with the proxy

wanton tangle
#

bruh

bold wharf
#

plugin messages for stuff like that is generally perfect, either using the built in bungeecord channel, or, a custom channel if you want your own logic

cloud iron
wanton tangle
#

so the invocation.source() will never be player??

bold wharf
#

it should be the player if the player execues it

wanton tangle
#

but you said its only proxy commands

bold wharf
#

or at least something associated with the player, iirc, see the JDs to see what that method returns and what extends that return type

#

the command exists on the proxy.

#

the proxy intercepts those commands

#

if the player runs a proxy command, it will run on the proxy

wanton tangle
#

ok I see so i gotta do some additonal mc server side stuff to register the proxy commands there too?

bold wharf
#

no

#

once again, the proxy interecepts all the commands

#

if the command is registered on the proxy, and the player runs a command that they have perms for, the proxy will intercept it and handle it, running the command

#

For their specific case, stuff like /send, sometimes you want such a command to exist on the proxy so that signs or command blocks, etc, can run such commands

#

if you want something on the server itself to run a command, the command needs to actually exist on the server

#

but, that doesn't show relevent to your case

wanton tangle

bold wharf
#

on the proxy

I'm reading the velocity api docs and it says to reply to a message I have to do:

source.sendMessage(TextComponent.of("Hello World!").color(TextColor.AQUA));

However when I try to do TextComponent.of, IntelliJ tells me that such a method doesn't exist, anyone know why?

Does "CommandSource" has an alternative method for its name who executed this command?

#

source#getName does not exist and I want to safe the name of the player / console. I could make an instance check if it's a player and then get his name and if it's not a player, then write as console, but isn't there a better/clean way?

burnt dragon
#

source.get(Identity.NAME) would work

The reason we don’t have this in the api is that plugins check for name.equals(“Console”) more often than you’d think

There is a player named console

For that reason alone this is a hard no from us

Hello, how to switch player's server from a spigot server please?

bold wharf
#

use the bungee messaging channel

hollow sleet
bold wharf
#

yes

#

velocity implements that channel itself

hollow sleet
#

so it's working like this?

unknown.png
bold wharf
#

No

#
  1. wrong channel name, there is an example pinned somewhere or something
#
  1. you still have to actually follow the bungeecord channel spec, just sending a server name is gonna do nothing
hollow sleet
#

okay thanks, but where can I find the channel name

bold wharf
#

it was like bungeecord:main or something for 1.13+

the forge servers must be identical if you are gonna switch from one forge server to another

Do I have to close previous connection after forwarding/redirecting the player to another server in ServerPreConnectEvent with event.setResult(ServerPreConnectEvent.ServerResult.allowed(newServer));

#

Im not even sure if forwarding like that works?

#

But since this is on the server pre connect event, there shouldnt be a connection yet...

Players get disconnected when doing it this way though... it says read timeout.

Heyo! Is it possible to get a connected server's logger through Velocity?

fossil sundial
fossil sundial
# wanton tangle Players get disconnected when doing it this way though... it says read timeout.

I think you’re confused as to what you’re doing here. Velocity will itself handle all of that. The connection to a possible old/previous Server gets automatically aborted on the https://jd.papermc.io/velocity/3.0.0/com/velocitypowered/api/event/player/ServerConnectedEvent.html

ServerConnectedEvent (velocity-api 3.1.2-SNAPSHOT API)

declaration: package: com.velocitypowered.api.event.player, class: ServerConnectedEvent

fossil sundial
#

This may clear that up a bit:

#

To set the first server velocity attempts to connect you to use the PlayerChooseInitialServerEvent

#

If a player gets kicked or disconnected from a server you can listen to the player kicked event

#

And only if the player uses the command /server or the bungee channel is used by the server of another plugin is trying to connect the player somewhere else
Then is the only time ServerPreConnect is fired without your plugin having made the decision

fossil sundial
wanton tangle
fossil sundial
wanton tangle
fossil sundial
#

if there is none then you made the client wait for too long

wanton tangle
fossil sundial
#

I assume this only happens on first connection?

#

Cause this code doesn’t cause it for me

wanton tangle
#

its the first join on the proxy yes

fossil sundial
#

there’s a hard 10s limit to join first. This is a known problem which is why I suggested you use the PlayerChooseInitialServerEvent

#

we cant fix that

wanton tangle
wanton tangle
fossil sundial
#

Its a client limitation. From the first packet the client sends to the client joining must not exceed 10s or the client will abort the connection

wanton tangle
fossil sundial
#

I don’t know what to tell you. But I myself can’t reproduce your problem

#

and the client hitting the limit is the only reason you’d get a timeout here

#

How long are you holding the event for?

1.19 servers, 1.19 client, velocity 3.1.2-SNAPSHOT, latest build

the choose initial is just there so you see that the original server is not the same server

you can remove that, no change

wanton tangle

try running it with these:

player-info-forwarding-mode = "modern"
force-key-authentication = false
forwarding-secret-file = "secret.txt"

When trying it with player-info-forwarding-mode = "none" (default) I get directly kicked with Unknown login plugin response packet! message.

It is something with the server you’re being sent to if nothing else

#

Try another server

wanton tangle
#

The only thing I can think of is another event of my plugin interfering somehow...

I can’t reproduce your issue.
Also your use is unsupported (piracy).
If you find a way to reproduce it with a supported setup and it is indeed caused by velocity then please open a new issue on GitHub

wanton tangle

Those run in sequence
PreLogin > PermissionSetup > ServerPreConnect > ServerConnected

I left out the events that are fired between them

wanton tangle

Another event is interfering

Now going to add one event after another and find out which one

#

brb

#

found the culprit... @fossil sundial I thought u could do long running stuff on the ServerConnectedEvent

guess i gotta use the postserverconnectedevent

nevermind. the stuff I was doing in that event has to be done in async

how to get backend server online? only ServerPing?

final lynx
#

anyone know how I can disconnect a player with a displayed component without printing it out on the console? Or print out the console with a shorter version instead of the component shown to the player

burnt dragon
#

just log something to the console before you disconnect them?

final lynx
#

i mean it still shows "ABC disconnected: (long reason)"

burnt dragon
#

well yeah but that solves your issue of "unreadable thing being printed to console"

magic forum
#

When that's done, V0.2 is released

#

This is very inefficient way, It donwloads the handshake AGAIN just to check if it's still the same as before (because the server admin could have restarted the server to updated a mod in the meantime and the handshake would then be different)

#

This can happen, so I want to use checksum to make sure the server hasn't changed, and not have to download the entire handshake every time someone wants to switch servers

#

Also right now it just prints "Resync" needed in the console. This is a placeholder for what I'm gonna do I V0.3, which is this "kick to reset"-packet

#

Because ping forwarding is not high priority right now

unknown.png
#

So

#

that's the plan

agile ore
#

Does anyone know what might be causing this?

#

Disconnect packet works normally

#

But there's a tineout on clientside

wanton tangle
#

Does stuff executed by the proxy.getScheduler() get executed in async?

fossil sundial
tired quarry
#

literally such a dumb regression that they literally know about

magic forum
#

I'm trying to make the workaround as invisible as possible

bold wharf
#

Reset packet induces a unstandard state transition that forge agreed they didn't wanna deal with years ago, especially as it woulda caused issues across the board with nothing expecting that and proxies being shaky as all shit back then

magic forum
#

I have looked at how forge works and have adapted my plugin after that to make forge as stable as possible

#

My plugin keeps track on forge snapshots config files and modlists and maneges them so the client always is synced

@brisk steeple heads up
The 1.19.1 update will add modern forwarding v3 to Velocity

v2 has the Revision 1 player key type
v3 has the Revision 2 player key type

  • the uuid it is signed against (if present)

If you ask for v3 you may get a v2 response.
The revision 1 key from 1.19(.0) is unusable on 1.19.1 so you must ignore it on that server version

This scenario may happen if you have ViaVersion somewhere in the pipeline but is technically still valid

Thanks for fabricproxy-lite!

the client has an idle handler on the network connection

#

you have 30 seconds to start sending packets to the client from when the thing connects before it DC's

agile ore
#

well the backend server sends packets but it doesn't seem like velocity forwarded them

net.minecraft.network.handshake.client.C00Handshake@7bde6b57

net.minecraft.network.login.server.S02PacketLoginSuccess@1b637b4f
#

im only receinvg these packets on my client

#

and backend logs say that the client has connected

unknown.png
bold wharf
#

yea, those packets are only handled between the proxy and the server

#

you can't send login start to a client which is already joined, etc, and so velocity manages that mess

#

you basically need to get the client into the play state within a reasonable amount of time

agile ore
#

Does Velocity has it's own config management? Or should I just use Gson?
