So if ProxyServer#getServers() is deprecated, what is the correct means of dynamically registering new servers on bungeecord?
Dunno if ConfigurationAdapter#getServers() will do the same thing...
Looks like it might. Would ConfigurationAdapter#load() be needed to be called in this method?
deft trail
use this anyway: https://github.com/PaperMC/Waterfall/blob/master/BungeeCord-Patches/0026-Add-dynamic-server-addition-removal-api.patch
molten jackal
I mean the copied version of the method is a copy of the map... I won't be able to modify it and have it actually be used.
I'll use the ProxyConfig
Thanks broski
molten jackal
I believe I may have found an issue with bungeecord/waterfall (probably bungee).
When an event is called, it does not call event methods that are inherited from super classes.
For example, I have ServerListAppearance which is abstract and has a ProxyPingEvent listener. When I have LiveAppearance extend ServerListAppearance and then register a new LiveAppearance instance as a listener it does not call the inherited event listener.
molten jackal
Odd. Because the exact same thing works in spigot perfectly fine.
trail plume
Bukkits event system goes to find the handler list on the event
Bungees system doesn't care about inheritence whatsoever
molten jackal
What is the benefit of not acknowledging inheritance?
trail plume
"it's easier" i guess
molten jackal
π
trail plume
bukkits event system is superior, imho
molten jackal
Yeah
sly crown
still sux
molten jackal
Still sux but superior.
Wish there was a way to override the eventhandling system for bungee π
trail plume
Bukkits system is more expansible I guess, bungees system makes sense for a simple event system
molten jackal
Yeah I suppose its simple. However its frustrating, because I've found that my code everywhere except for bungee ends up being beautiful and effective. 
trail plume
I gotta deal with multi-plat for mcmmo down the line
Probs just gonna use kashikes event system
molten jackal
Dunno if this is ideal, but my solution was to just have an event method for the same event that just calls super.onClientPing(e) π
long crypt
You may also try using Delegate instead of inheritance.
sick skiff
trying to add/remove forced hosts in an active listener and it isn't working
sick skiff
any way to do so?
lean gobletBOT
"isn't working" is a pretty vague description of the problem
sick skiff
nevermind, i'm going around it by using the event system
i was trying to set the bungeecord config for an active listener, which is impossible.
molten jackal
Why does custom bungee channels need to have a semicolon?
naive finch
Does Waterfall have a Maven repo?
trail plume
Mojang requirement, channels are namespaced
molten jackal
Is there any way to send a TextComponent to a player through the plugin messaging system (spigot -> bungee -> player)?
trail plume
But, why?
Like, yea, you could, you'd just need a plugin on the proxy to deal with the message you send
molten jackal
Because I want to announce a json clickable message on the entire bungee server from the bukkit.
Would I just have to parse it as a raw json and send it through a custom message channel?
molten jackal
Right
wary inlet
I have a feeling I've set the sources up wrong in IJ; the entire Waterfall-Proxy dir is marked excluded (the IDE feature) and certain completions just don't work (presumably because of absence of certain dependencies in the IDE's eyes)
How would one actually go about doing it? ./waterfall b then opening the root dir of it didn't seem right
bleak current
./waterfall p then you'll open the root dir
building isn't needed, just patching is good enough for IDE usage
opening the root dir works just fine, so-called super pom.xml takes care of pointing IDE to correct place
cerulean kettle
Just wanted to share that bungeecord crashing/not responding at bot attacks is because waterfall doesnt remove the connection from the pipeline when closing it so the pipeline overloads and this happens on premium or no premium servers.
Would be nice to get this fixed in a official update :)
lean gobletBOT
bungeecord or waterfall? xD
bleak current
doesnt remove the connection from the pipeline when closing it so the pipeline overloads
what
if you close the client then it's... closed and not handled anymore
cerulean kettle
@bleak current Yeah i mean, it closes with delay of 250ms normally.
you need to do .flush() before closing it
i dont know too much about connections, im sharing what it seems to be working
some methods already implemented .flush() before closing, some others didnt
and when i say bungeecord i mean waterfall, travertine, etc

p.v.MyBenchmark.testThrow thrpt 20 1969040.690 76668.714 ops/ms
spring bloom
3k ops per ms is very fishy
3 million
that's like what 3 billion per second
slow throw loses by like 1000x
trail plume
That's more for a baseline than anything
spring bloom
that's like your cpu's clock speed
trail plume
Like, I knew throw would be slower, I have no idea of the relevance of that, however
It does paint a wtf as to bungees handling of packets
spring bloom
it's really hard to bench what a return is to a throw because that return is probably being entirely nuked
spring bloom
it's probably measuring the jmp call back to whatever is benching
trail plume
My brains dead; but it was only really there to serve as some level of baseline, a return of a boolean is going to be thereabout
spring bloom
well I guess
trail plume
Well
spring bloom
in any case
trail plume
I just added a field to prevent JIT being JIT to some degree
Benchmark Mode Samples Mean Mean error Units

p.v.MyBenchmark.testThrow thrpt 20 2003033.271 61452.801 ops/ms
at first, I thought it was unboxing as I derp'd and used a Boolean, then I went to go fix that and saw no change :L
spring bloom
update gist or riot
trail plume
der
either way, seems to validate that the cost of returning a boolean vs throwing a cached exception really ain't that much of a concern

How does the plug-in messaging channel work for inter server communication? Please tell me it doesn't need a player because it uses it to relay the message
lean gobletBOT
it needs a player
any plugin message needs a player
it's suggested to use a proper pub sub system like RabbitMQ or redis (if you have that already running) for anything bayond basic player information sharing
gleaming sedge
Yes, I know that is bad, I am asking how it works
Is the message sent to the player, who then relays it to the server, or how is this done?
I use plugin messaging to communicate with my mod, but I haven't really used it for bungee much.
lean gobletBOT
the message is relayed by the bungee
server -> bungee -> server
it never reaches the client
molten jackal
Which event should be used for disconnecting players on login due to a ban or something of the sorts? I need access to their UUID, so PreLoginEvent is ruled out. PostLoginEvent does not implement Cancellable, so I can't prevent them from logging in on this event. Unless, if I were to just call the kick method on the ProxiedPlayer who is logging in, don't know if that will cause flickering though.
By flickering I mean, when they join they see the game for a split second then are disconnected.
molten jackal
Okay. Trying that

probs something wrong with their deployment
based upon that fact that it's tryna refer to a token and not an actual set value
brazen walrus
It actually works if I retrieve 1.5.0 instead of 1.5.2

You're registering it on the proxy
You're not registering it on the server itself however, which is literally the one that is bitching about it not being registered
trail plume
They didn't register the outgoing channel on the player
Oh, that's not needed, I forgot how janky this entire API is
But, I'm inclined to believe the server
if it's saying that they didn't register it, it clearly wasn't added to the channel registrations for some reason

Is there an event that fires when a player leaves a server, and the proxy is preparing to connect it to another server?
lean gobletBOT
there are events for that but they happen in a different order than you think

there is a connect attempt event or something like that

proxy connects player to other server -> connection to old server is closed

lean gobletBOT
so because your setup is broken you changed the java version? 
sly crown
can you not target down?
trail plume
I know that they pulled support for compiling against 1.5, which is fun because maven still targets that
ysl said that it drops a warning
am assuming that it still compiles just fine
sly crown
Didn't build without it.
sounds like 1.6 didn't work at all for him
which i kinda doubt is normal
unless they pulled support for targeting 1.6
trail plume
maaaybe, hm
stone fiber
they did pull support for targeting 1.6 in java... 11? 12?
stone fiber
maven compiler dropped support because java dropped support
outer cosmos
And md didn't. Just why?
stone fiber
md believes that newer versions of java just add "fluff"
and that 1.6 is the true java
or some such nonsense
shell lagoon
I prefer Java 1.4 or lower, generics are garbage anyway /s
outer cosmos
π
stone fiber
anyway, here's the deprecation policy for supporting old java targets. http://openjdk.java.net/jeps/182
To sum it up:
In JDK 9 and going forward, javac will use a "one + three back" policy of supported source and target options.
However, it appears they are just "reserving the right" to use the "one + three back" policy, but are really allowing "one + five back" for JDK 12.
outer cosmos
I think the one + 5 has changed because of the LTS cycle.
stone fiber
I expect theyll drop 7 shortly as well
8 is going to hold on though
their "policy" is 1 + 3 but Java 8 being LTS throws a wrench in that
trail plume
Lol, I just had a peek
stone fiber
then again, maybe theyll just tell you to go use java 8 to target java 8
trail plume
Only reason we got 1.8 for -API was he seemingly wanted to use lambdas for some loottablestuff
stone fiber
I remember when MC itself had moved to 8 but he still refused to bump the API
at least now he finally did that
Im sure if you sent him a PR that wasnt pure enough 1.6 he'd reject it though
shell lagoon
I like repeating my generics
trail plume
I mean, it just looks like typical "this is the rules, unless it's me"
outer cosmos
Stefvanschie Java generics are kinda bad. No runtime generics.
stone fiber
compile time generics is still better than no generics

With chat event is there a way to get the whole message being sent including displayname on that particular server?
bleak current
display name?
you mean a name held by a plugin in your backend server?
such as /nick etc?
high lily
No he means like the name next to the message that was on the server, like the suffix and prefix I think
bleak current
What @high lily said
that heavily depends on a plugin where you get that info from
for example if you're using luckperms then you can fetch the metadata yourself on chat event

#waterfall-help but it looks like an issue with Bungeecord not waterfall itself
stark bone
This is a development issue. Due to the fact I am using a modified Forge server with an IP forwarding PR
I wan't to know if this is within bungee or an issue on my side
As I expect forge_support to help but apparantelly not
bleak current
very likely happens in bungeecord as well
so basically something from the server sent invalid commands info
stark bone
Well exactly
But its a forge server. So why is waterfall not supporting it when "forge_support" is enabled?
bleak current
being a forge server does not really excuse server sending invalid commands info
stark bone
yeh...
Basically, im messing with forge source to let the server support ip forwarding
but im failing on this point. I want to show if its waterfall playing up
or forge sending random shit
bleak current
forge_support covers only passing through and doing workarounds for its plugin messages (FML messaging channel etc.)
stark bone
hm
bleak current
so that it'd simply work
it does not enable "allow broken shit to be passed through and ignore broken stuff even though it's necessary for me to work" mode
stark bone
Alright
I guess it's time to figure out why the forge server is sending broken shit
just trying to work my head around whats going on
bleak current
simply figure out what's sending invalid brigadier commands info; your clue is a mod what... registers commands in odd way(s)
bleak current
show me that pr
bleak current
shouldn't affect anything related to the commands
unless forge broke something somewhere
stark bone
I need to push some changes
I basically want to get IP forwarding a thing in forge
and I am going to PR that
but then attemtping to join everything broke
and it looked like empty brigadier commands are being sent
bleak current
though why do you want to get this inside forge itself?
stark bone
to enable ip-fowarding?
bleak current
why wouldn't a (core)mod be sufficient for that?
bleak current
do you have any facts to back that statement
anyway, if you aren't touching anything related to commands then it's not your problem
it might be vanilla's or forge's
stark bone
Thank you
bleak current
haven't needed to pull up vanilla server yet (using fabric for example + a mod for bungee/velocity forwarding support), can only tell using that tbh
stark bone
I guess I will investigate. As theres no decent forge proxy atm
bleak current
oh boy it's gonna take a while
or not
alright, pure vanilla with bungee forwarding seems to work ok
stark bone
not with ip-forwarding tho?
bleak current
bungee forwarding, in other words "ip forwarding"
which does literally what you want to do
stark bone
Oh yes
I saw this
Luckily Fabric doesn't send random shit to the player causing waterfall to freak out
I want to figure out why forge is sending random stuff first...
sly crown
forge does a bunch of handshaking to sync mods and registries and such
fabric by default does none of that
there is a fabric-networking api that lets mods do some of that, unsure how/status/etc tho

- does not happen with spigot

what's left?

Well, lex has spoken apparantelly
However, was a bit hurtful to have some messy test code im working on insulted

and there's nothing wrong with that

craggy furnace
Mute plugin blocks players from chatting in bungee level, I need to detect when player writes something in a server while doing an action
My problem is that blocking chat in bungee level will not trigger AsyncChatEvent in server
So, If I have chatEvent blocked, how can I make so that spigot would still detect asyncChatEvent?
random comet
if its blocked on waterfall why would it matter
craggy furnace
Because a plugin needs input from chat to do a specific task
It shouldn't care if the player is muted
sly crown
if the chat is blocked before it gets the to server, how is the server supposed to send an event
lmao
make your own bungee plugin to detect it proxyside
random comet
you would need to use your bungee plugin to send a fake chat message if thats the way you want to do it
which seems very off to need to do to me
craggy furnace
Yea, wouldn't be able to check if player is doing that action
It's better to just check for if the player is running some kind of command and cancel the action
And allow it only when the player is not muted
trail plume
That's not waterfall
Yes, but that message is not from waterfall
Probably a plugin or something stupid, idk
But, you literally will not find a mention of that message on the proxy itself
no
More than likely you have some plugin that tried to connect to another server
So, don't do that?

I have found that PostLoginEvent does not have a server for the ProxiedPlayer yet. It also looks like there is no event for when a player joins the proxy fully and is fully connected to the server. What should I do? I'm looking to send a plugin message to the server they have connected to, but only when they join the entire proxy. So when swapping servers, this should not be called.

I'm having trouble sending a message to a player from a bungee plugin. I initially tried TextComponent.fromLegacyText, but nothing was being sent to the player. I afterwards tried to use the chatcomponent API, but everything appeared warped. I tried simply using the normal TextComponent API and kept using .addExtra, but that wasn't working either. So I made my own method for legacy text to a single basecomponent... nothing is being sent to the player. I had the BaseComponent print out a json message, and the "toLegacyText" version. Both looked correct, and using /tellraw in game with the json worked perfectly... So finally I tried something like from.unsafe().sendPacket(new Chat(json)), which also sent nothing to the player.
The text I am trying to send is simply a light purple and bold "Teleport."
I must be missing something blindly obvious.

It works with the chatcomponentAPI, it just doesn't come out right (As in all white, bold doesn't set, etc), so it's not client

Why does Waterfall load & enable plugins while their dependencies have not been enabled? I'm depending Holmium-InventorySync on Holmium which does a tonne of required work before invsync can load. invsync has depend: [Holmium] in its bungee.yml, so should see it?
oh it's because the platforms differ on depend vs depends, of course...

@Sβweβdzβ there is a ServerConnectedEvent and a ServerSwitchEvent that should do what you want

Is there a way for me to check if player is pinging the server with an unsupported protocol instead of just checking the int?
For example atm I just use ProxyPingEvent#getConnection().getVersion() < 47 (47 is 1.8) to compare.
civic valve
what do you want to do?
proper rampart
I want to "tell" them to use x version instead of the unsupported one.
civic valve
why don't you want to check the int
proper rampart
i'm asking if there's an alternative
civic valve
no
proper rampart
thank you
proper rampart
i was thinking more in sort of a check between the player and the bungee version itself
so if my bungee supports 1.8 - 1.15 then any protocols except those will get my message
i was just wondering if it's possible for me to make such a check
civic valve
Protocol numbers are also kept in net.md_5.bungee.protocol.ProtocolConstants
if you don't want random ints lying around
proper rampart
that's exactly what i'm looking for, thank you

ProxiedPlayer#getAddress() is now deprecated. I'm assuming ProxiedPlayer#getSocketAddress() is what we need to use. Am i missing something or is there an eaiser way of getting just the IP without port?
as socket address would be (example) /172.13.256.12:60553
lean gobletBOT
just call getAddress on it
(after you checked if it's an netSocketAddress of course)
lean gobletBOT
*InetSocketAddress xD
stark bone
ahhhh
I got you
Thank you
InetSocketAddress addr = (InetSocketAddress) player.getSocketAddress();
addr.getAddress();
This is correct right?
After checks and that
lean gobletBOT
yeah

hi, so I want to change the "Version" name from services like mcsrvstat.us (https://mcsrvstat.us/server/mc.divinerealms.us)
I want to just say "Join with 1.8-1.15" instead of "whatever (Waterfall)"
What I've tried is this: java @EventHandler public void onPing(ProxyPingEvent proxyPingEvent) { if (proxyPingEvent.getConnection().getVersion() > Collections.max(ProtocolConstants.SUPPORTED_VERSION_IDS) || Collections.min(ProtocolConstants.SUPPORTED_VERSION_IDS) > proxyPingEvent.getConnection().getVersion()) proxyPingEvent.getResponse().setVersion(new ServerPing.Protocol(messagesModule.color("&eJoin with 1.8 β 1.15.X"), proxyPingEvent.getConnection().getVersion())); }
But for some reason when I try with mcsrvstat for example it says
is there a way to do this with a plugin or will I have to edit the source of waterfall itself?
mcsrvstat.us checks protocol 4, mcapi.us checks 573
but if i do that then actual players that ping the server with those versions will not be able to see the player count
for protocol 4 i will just add another check, but for protocol 573 i want them to be able to see the player count (my server is 1.8-1.15 even thought i use travertine, i disabled 1.7 with viaversion)
ok now mcsrvstat.us shows what i want, but for mcapi.us which uses 573 i still can't get a solution
actually i guess no one will use 1.15
they will more likely use 1.15.2 or 1.15.1
so i guess 573 can go too
yep I've solved it now
lean gobletBOT
uhm waterfall has a config option to set the version string
oh wait, you wanted to have conditional version strings based on whether or not the user uses a supported one

@arctic jacinth What changes did you make? The thing I did was adding the ProtocolConstants. Cannot join the 20w06a server. Did you modified something else?
trail plume
gotta fix protocol constants and the entity map
also, gotta watch out for any entity metadata changes fuckin' up the map
(Which is often why these days I just forcefully disable metadata remapping on "newer than supported" sips tea)
arctic jacinth
Just duplicated the 1.15 entity map and added a new command thingy for the available_biomes argument
The protocol version for 1.16 is 701
I would like to add waterfall patches to that but donno how
outer cosmos
Ah ok thanks. I've updated the Protocol version already and used the 1.15 entity map for 1.16. The command thingy is the left key in my modification.
You're running a fabric server? That's probably the second key component why my vanilla server is not accessible using bungee.
trail plume
ah, nice, no metadata changes
huggles mojang
Make sure that you have ip_forwarding disabled
vanilla doesn't like that
arctic jacinth
Yes
You need a special mod in fabric

part of why I don't care to add support for snapshots
it's literally useless to the majority of people, it's only really on release where it's a nicety
arctic jacinth
Is the entity remapping thing really necessary? What can we do if they change something? Just disable it?
trail plume
in bungee, yes; In waterfall/travertine, no, that can be disabled
saying that, disabling introduces some quirks, which ain't always ideal

you could do that, yes, but plugin messages might not be the best tool depending on what you want to do

What has to change in BungeeCord/Waterfall each time a new Minecraft version is released to support the new version?
bleak current
protocol version must be added into supported protocols list and if needed, update packet read/write methods
trail plume
Somebody directed md to a waterfall patch, and now, he's basically got that connection init event, whih I can agree that the naming of is bleh, but "Client" specifically in there was a bit of a iffy one given that people fail to understand client/server relations... But, he also pulled in some delombok stuff from like 5 years ago lol

You can handle chat messages players send

That's what I figured it was but the issue is is that for some reason it's not handling correctly when it's being fired. Probably something on my end.

Wild question, but is there a way to switch someone between 2 different waterfall proxies?
lean gobletBOT
the same as putting a proxy in front of your minecraft servers, just that you have one in front of your other proxies
you'd still have a single point of failure though
and I don't know of any public solution for that
I guess the use cases for such a thing are pretty limited

What is the getKeys(true) alternative for Bungeecord/Waterfall ?

I tryied this
but this code don't work :/
besides that it looks pretty horrible
I want to loop all properties in the yaml and check if key end with "." + Config.lang ( like "foo.bar.en" )
i'm pretty sure you can achieve the same thing without getting all the keys recursively
what do you want to do?
I want to loop the yaml language file in my jar and create a new file like fr.yml and put all key end with .fr in the main language file
( my english is verry funny )
outer cosmos
bleak current
just split the language file up into separate files
trail plume
That would just get gross to manage, resource bundles are also petty much a defacto standard for this type of thing
bleak current
no no
the main language file contain all languages
but why
that's gross
it's most easy for me
alright, but then resource bundle aka .properties file is a lot better choice for you
trail plume
if your intent is to provide that to the public and want people to contribute changes, etc; that's going to go to hell fast
bleak current
this file is in jar plugin
outer cosmos
When someone will not follow business standards...
bleak current
yes but are you going to publish that plugin somewhere?
e.g spigotmc or so?
yes

So, I'd suggest using a sane setup which is literally already supported by the java community as a whole
lean gobletBOT
why would you take a good system and make it worse?!?
bleak current
if you split up language files per locale then it's a lot more readable
trail plume
I mean, it's a lot more readable and extendable

it saves me from switching files every time

Heck, if you use message bundles, you can use programs for managing that type of stuff

Hey @trail plume, sorry for interrupting, just wanted to ask before I dive into the code itself, is there any way to connect proxy to proxy, or do I need to write my own "super proxy" for this? Thank you

fervent geyser
Sorry, thanks

Mineplex does that with their "BungeeRotator"
and their source code leaked so i mean
it's not that hard to find the code π
sly crown
i mean, it's also just about a one line code change to allow a proxy to connect to itself
it's just that it adds a lot of complexity, configuration requirements, plugin support, etc to work "fully"

i mean, i fail to see the reason why you'd wanna do that
Only reasons I've ever seen people give would be better solved elsewhere

easier to just change your breakpoints to only stop the active thread

You'd have to query mojangs API, waterfall does not have a user cache
Unless you intended this for paper, then use #paper-dev

nah
im on waterfall
ill make a method to do it with mojangapi
i just didnt wanna do that

Just making sure. lol
Then ya you'll need to query mojang, there's no other way that I'm aware of.

You can look up a UUID every minute for every unique player
but that ratelimit isn't concrete, mojang will throttle if you're way too spammy, about 1k requests in a second

just doing a /getreports thing
where it gets the reports of a player out of a database
based on their uuid

if you can't do it yourself then you should really think if you need a fork

I'm currently using a custom build of bungee (same happens when patched with waterfall)
The client kicks me out of the server when attempting to load the command suggestions
Does anyone know where the issue might be?
bleak current
snapshots huh?

Bit of a weird one here,
When doing this ```java
@EventHandler
public void onPreJoinEvent(PreLoginEvent event) {
//Get connecting clients protocol version
int getProtocolVersion = getClientValidVersion(event.getConnection().getVersion());
//Kicks player if version not correct Before they even get to PostLogin
if(event.getConnection().getVersion() != getProtocolVersion) {
ProxyServer.getInstance().getConsole().sendMessage(new ComponentBuilder(event.getConnection().getName()).color(ChatColor.YELLOW).append(" Kicked due to version mismatch").create());
event.getConnection().disconnect(new ComponentBuilder(Main.PREFIX).append("Please join using version ").reset().append(getVersionMsg).create());
event.setCancelled(true);
}
}
https://pastebin.com/mS7YqbbH
It seems the null pointer is on this line.
event.getConnection().disconnect(new ComponentBuilder(Main.PREFIX).append("Please join using version ").reset().append(getVersionMsg).create());```something in your component is null
stark bone
Ok... so never mind.
event.getConnection().disconnect(new ComponentBuilder("This is a test").create());
This still causes a nullpointer
bleak current
connection might be null then
if that gives exception as well, post its stack trace as well
stark bone
The stack trace is the exact same as the previous one
sly crown
split event.getcon into its own var
stark bone
Ok..
So the issue was
event.setCancelled(true);
if I add that line, i see the null pointer in the pastebin above?
bleak current
simply set a cancel reason
event.setCancelReason(...)
and cancel event
that'll do exactly what you need

Hello, I was wondering what this is:

If you hold the channel name at the top I think you get the description.
Well, or not apparently

Ah, yes, the perfect place for the channel description: the members list.

the irc "killer" has a lot to learn

this.getServer().getMessenger().registerIncomingPluginChannel(this, "BungeeCord", this);
is it correct registering incoming messages on this channel?
@Override
public void onPluginMessageReceived(String channel, Player player, byte[] message) {
this.getLogger().log(Level.INFO, channel + " got message");
if (!channel.equals("BungeeCord")) {
return;
}
ByteArrayDataInput in = ByteStreams.newDataInput(message);
String subchannel = in.readUTF();
if (subchannel.equals("EquipmentRequest")) {
short len = in.readShort();
byte[] msgbytes = new byte[len];
in.readFully(msgbytes);
DataInputStream msgin = new DataInputStream(new ByteArrayInputStream(msgbytes));
try {
String somedata = msgin.readUTF();
this.getRedisUtility().savePlayer(Objects.requireNonNull(Bukkit.getPlayer(UUID.fromString(somedata))));
} catch (IOException e) {
e.printStackTrace();
}
}
}```
i have this code in the same class
but it doesnt execute, even first logwhy don't you use your own channels?
relying on BungeeCord channel is... dangerously brittle
nocturne widget
I got it... hmm.. i thought there is no need to invent wheel second time
bleak current
what do you mean invent wheel second time
nocturne widget
but wait, Im not using it to send responses
bleak current
you'll just use different channel name than "BungeeCord"
bleak current
"yourplugin:identifier"
nocturne widget
but look, im just sending request here
nothing more
my "client" server processes it and thats it
nothing more happens
still shall I implement my own channel?
bleak current
yes
nocturne widget
Ok i figured out that I was sending message to player, not the server

Hey, would anyone happen to know what the different states in ServerKickEvent mean? They're not documented unforuntely
Like, does CONNECTED mean that the player was connected to a server and was kicked, while CONNECTING means it was trying to connect to a server and was kicked? That would make sense, but you never know with BungeeCord π

Hello, is it possible to start a waterfall proxy without any servers configured and add them programmatically later on? (Well yes, that works)
But what not works is me connecting to the proxy. I have added a server but the Proxy complains that I have no default or fallback server.
lean gobletBOT
might not be possible to set that one just with api
weak estuary
We do it like that. But I set a fake server as the servers only configured server and gave it the highest priority
And then we select one using a plugin
Basically I couldnβt get it to work without the fake entry for some reason, but it also means that if we fail to connect them using the plugin, nothing funky happens
signal mica
Okay thanks. Looks like I will use some kind of workaround then.
warped loom
does someone know why getAddress was deprecated?
trail plume
read the javadocs?
warped loom
and how does one get the address from the SocketAddress class?
sly crown
did you try reading the docs
warped loom
yeah i've done it )=
trail plume
The actual javadocs for SocketAddress?
warped loom
yeah, i think i'll give up.
trail plume
this is basic java
if you have an interface, and need to reference a more concrete impl of a class, what do you do?
shell lagoon
raises hand
warped loom
but SocketAddress is not an interface
warped loom
i just dont know "protocol dependentent implementations" that could subclass that. I'll search further
trail plume
oracles javadocs literally tells you what the known subclasses are
brazen warren
What is the best way to report bugs ?
Or speak to a developer ?
When offhand is enabled on the server, a sword's reach is 5 blocks ? Is that correct, because this is defined as hacked clients.
brazen warren
wich channel ?
trail plume
Generally one of the paper ones

Hi, I have a question regarding an async method, basically my method retrieves a ServerInfo from the name of the server:
public static ServerInfo getServerInfo(final String serverName){
//getServerInfoMap returns Map<String, ServerInfo> from the proxy.
return getServerInfoMap(proxyServer).get(serverName);
}```
If it's possible to make it Async using the proxy scheduler, what would be the way to achieve it?is there something like byof for waterfall, for lazy poopl like me?
lean gobletBOT
good enough π
sly crown
i mean it is. literally all set up too. just gotta rip out the 2 patches it has and add your own
lean gobletBOT
patching is great, we just used to just plainly throw stuff into Bungee and ugly-ly merge upstream
fluid stump
Will changing the displayname still send the original name to the server?
Nvm just read the docs, but is there any way to change unique name?

what the fuck did i just witness

so the static is the problem i think becouse it creates an individual think ?

he was instantiating a class extending BSS , which already extends Plugin. That's illegal

oh
yeah you can't have multiple instances of plugin main class now
bungeecord started enforcing that

so then I get why it worked until now

re: empty packets, this has apparently been an issue when setting the tab complete suggestions to an empty list
dunno if you want to include that in "bad plugins" but i assume the server should handle that properly somehow
though i'm not 100% sure how to reproduce, it might be in conjunction with other bad plugins possible?
trail plume
there was a plugin a good while back that was breaking servers tab complete
might have been premiumvanish iirc

all i know is some people were getting empty packet errors with bungee + worldedit suggestions and switching to waterfall fixed it for them

There's this 1000+ member minecraft discord server that popped out of the ground from EDM articles about an in game music festival
At the moment the plan is to have a multi server network to spread players around
and the goal player cap right now is 330
Something we want to accomplish is having a single player be mirrored across all of the servers under the proxy
(the artist)
The only interaction on all servers they'd have to do is press a button
My question is,
how feasible would it be to mirror a single player's packets across multiple servers using a proxy level plugin or fork
Auth would be handled once, and the joining artist would receive packets from a central single server
The servers are all identical with the same world
