[ornate patio]

Hello I have a question I am developing a shop with a minecraft gui we can add buttons writeable with spigot / Bukkit or I have to pass with forge, can you enlighten me please thanks in advance

[rare flicker]

you can make inventory UI's

or if you're really cracked at plugin dev do smth fancy with fake armorstands and packets to have a 3d menu

but if you want a menu like minecraft's escape menu you'll have to use mods

[worldly ingot]

It depends entirely on what you mean by "button"

On the server side you're restricted to vanilla inventories and listening for click events. So in that sense, yes, you can create a button and you can texture it with a resource pack. You can also make use of negative font widths and inventory titles to render a custom background texture in an inventory, but you're still limited to static textures and a fixed inventory size. If you want custom inventory rendering for a custom button with highlighting, yes, you will need a client-sided mod

If you just want a simple button in an inventory, you can use items

[rare flicker]

negative font width?

pretty fancy way to make a background, wasn't even aware that this was a thing

[wary harness]

is this comming from spigot

Is there any settings to allow more packets to be sent

[ornate patio]

I just want to put the number of items to buy 😅

[rare flicker]

just change the amount of the itemstack

🇫🇷 par exemple si tu veut faire un shop ou tu vends 5 de fer, fait en sorte que l'itemstack du lingot de fer dans ton menu soit de 5 @ornate patio

[eternal oxide]

@vivid cave I filled out the rest of that packet java ClientboundRespawnPacket respawn = new ClientboundRespawnPacket( nmsLevel.dimensionTypeId(), // dimensionType nmsLevel.dimension(), // dimension nmsLevel.getSeed(), // Seed serverPlayer.gameMode.getGameModeForPlayer(), // playerGameType null, // previousPlayerGameType nmsLevel.isDebug(), // isDebug nmsLevel.isFlat(), // isFlat true, // keepAllPlayerData serverPlayer.getLastDeathLocation() // lastDeathLocation );

[worldly ingot]

Did you find it in BT?

[eternal oxide]

Yep you were correct it was the old name

[worldly ingot]

Yeah I'd figured that was the case. I hope all mappings are dropped in favour of Mojang mappings in the future

Right now it's a mangling of both lol

[quaint mantle]

Sup, I have a plugin which depends on a non-plugin library (I put the library in plugins/lib)
I added -cp C:\path\to\server\plugins\lib\* to the start command batch file, but it still throws classNotFoundError

[eternal oxide]

Windows search couldn't find the sky for looking.

[ornate patio]

the problem is for a server with friends and it should be possible to choose the number of items

[eternal oxide]

Same, I like Mojang mappings

[quaint mantle]

the dependency is set to compile

it fails because it cannot find a class in the library

it should be loaded to the classPath right? it is the right directory it's in.

[valid solstice]

Hello, how do you make a player invisible without removing any of their armor, weapon, and offhand

[vivid cave]

but like isn't there a way to say "you're controlling that new player now"

[eternal oxide]

Not that I can see

[solid cargo]

Whats the diff between AsyncPlayerChatEvent and PlayerChatEvent? One is run on the server thread or sum like that?

[worldly ingot]

PlayerChatEvent on the server thread, AsyncPlayerChatEvent on a separate thread

You should use the async one over the main thread one pretty much every single time

[solid cargo]

To fight chat reports is there a one which is better?

[worldly ingot]

What chat reports?

[river oracle]

None

It's not out yet

Can't remove something that doesn't exist bozo

[worldly ingot]

And we're also not going to encourage you to do it here either when it does come available ;p

You're on your own if you want to disable a player safety feature

[river oracle]

I'd happily help when the time comes but why bother worrying about something that hasn't been included yet

[solid cargo]

So im completely on my own for now?

[worldly ingot]

Yes

[river oracle]

It's not out yet so there's nothing to even do

[solid cargo]

Resources that fight it will get removed?

[river oracle]

Nah likely not

[river oracle]

Seriously don't even think about removing it unless you wanna dig through pre release 4s nms and figure it out yourseld

Then you can't even deploy those changes since the updates not even out on spigot or minecraft

[worldly ingot]

We won't remove them from the platform because that's not really our responsibility. If you want to disable that feature and harm your users, you're welcome to do that. We have other potentially EULA-violating plugins as well. Though we're not going to encourage you to publish it because we're not going to actively go against Mojang here

[vivid cave]

thank you!! but i guess i'm quitting this respawn packet cuz i can't spam it to the user

[worldly ingot]

But you're really fighting a non battle

[eternal oxide]

I just like to get everythign right 😉

[vivid cave]

^^

thanks so much for all your efforts!

[solid cargo]

Idk had idea of disablin via chat event -> cancel message -> broadcast it instead

Will try that when spigot 19.1 is out

[cunning canopy]

if I have a location like this (0, 0, 0) any way to make it so that I can subtract a block

like the way the player is looking

if that makes any sense at all

[river oracle]

I can't wait till 1.19.1 releases and all the devs come here to beg to tell how to disable it.

[solid cargo]

My users are my irl friends so i really aint harming them

[glossy venture]

how is the player chat reports player safety

[worldly ingot]

THEN WHY ARE YOU DISABLING IT?

Are you dumbasses reporting yourselves?

[glossy venture]

potential autocensor or smth

if they ever implement that

[worldly ingot]

JAVA DOESN'T HAVE A FILTER

Well, it does, but it's controlled by the server owner

It's had a configurable filter for like 3 major versions now

[solid cargo]

You never know when there is heated moment with ur homie and you get reported

[worldly ingot]

bro

[glossy venture]

i know but with the path microsoft is taking it may have one, its also nice to have more control over the chat system

[worldly ingot]

That's the stupidest shit I've ever heard

You calling 911 on each other too?

[solid cargo]

YOU NEVER FUCKING KNOW

[old cloud]

Some packets that deal with containers use the "State ID" field. Can someone pls explain what that field is supposed to do? Because I don't get it.

[worldly ingot]

Don't play with fire if you don't want to get burned. It's really not that hard

[glossy venture]

well why not disable it

[cunning canopy]

I am teleporting a sheep on top of a players head. When the player looks up the sheep is blocking the view. How can I like make it go a little backwards once you look up?

[worldly ingot]

iirc it's the id of the last container opened but I would have to double check that

The last recieved State ID from either a Set Container Slot or a Set Container Content packet
It's really just an arbitrary number

[quaint mantle]

I found this. https://bukkit.fandom.com/wiki/Using_External_Libraries_with_Plugins
I don't want to shade the library because I want to use it in multiple plugins.
I tried adding the classPath argument in the batch file: -cp "C:\path\to\server\lib\*" (Where the jar of the library is in the /lib folder). This did not work (ClassDefNotFoundError for a class in the library used) (I tried many variations of -cp path none worked)
I saw some stuff with "instructing the classloader to load the class" but that seemed too much for such a simple task.

[worldly ingot]

It's to make sure changes to an inventory are linear

[solid cargo]

Anyways. Take this, choco, to calm the fuck down

[worldly ingot]

I'm calm, but I'm just dealing with stupidity daily lol

I've got 3 dogs myself

[old cloud]

So its useless?

[worldly ingot]

I mean you can ignore it

[merry plover]

how to use for discord bot?

[worldly ingot]

They're inbound packets that use it

[old cloud]

Ye, but what does the client do with that information?

[somber sequoia]

yo is there any way to get the plugin version

cant figure that one out

[worldly ingot]

Not sure what the client does with it

You could probably send 0 for the state id. Again, I'd imagine it's an ordering thing

[old cloud]

ok lol, well thanks for the info

[worldly ingot]

What version are you using? If 1.17+, there's a libraries entry in the plugin.yml where you can declare Maven Central dependencies to be downloaded at runtime

Otherwise if you're using a custom library that you wrote, yeah, you'll have to shade and relocate it

Or, alternatively, make that library a plugin and have your dependents depend on it

[naive bolt]

what event would be fired on dripleaf falling

if their would be

[cunning canopy]

How do I hide an entity for certain players

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#hideEntity(org.bukkit.plugin.Plugin,org.bukkit.entity.Entity)

[cunning canopy]

thanks

[worldly ingot]

A PlayerInteractEvent is called for players, and EntityInteractEvent for things like arrows or snowballs. EntityChangeBlockEvent is also called in more generic situations

[cunning canopy]

I found hideEntity, but its deprecated

any other options?

[lost matrix]

Draft API

[cunning canopy]

whats that supposed to mean?

[opal juniper]

That it is new and not thoroughly tested and also could change syntax

but personally, it seems likely to stay

[cunning canopy]

so it means it can be ok to use afterall?

[opal juniper]

its deprecated so that you can see it in the IDE - just so that you know there are caveats with using it

[cunning canopy]

okay

will it work with older versions of the game?

[opal juniper]

depends when it was introduced

it has been there for a little while but not that far back

[cunning canopy]

how far back we talking?

[reef lagoon]

Why is it always always equal to 0 when i divide it?

[eternal night]

your list as best has one entry

1 / 2 = 0 in java int division

[reef lagoon]

I'm so stupid

[lost matrix]

I mean you create a new list for every player and then just put the player in it.
This means the list is always of size 1 at max.

[reef lagoon]

just the location of "list"

ty anyways

[reef lagoon]

yeah I saw it now mb

[cunning canopy]

any way to see on the docs when a method was introduced?

[lost matrix]

Nope. You should strive to support the latest versions only, if possible.
Backwards compatability should be a "nice to have"

[cunning canopy]

yes it definitly would

considering a whole ton of the playerbase is stuck in 1.8

[lost matrix]

Almost nobody plays this version anymore...

75% are on 1.17 and above. Even 1.12 has a bigger playerbase than 1.8

And writing plugins for 1.8 is an absolute nightmare. You can throw practically half of your code in the trash.

[cunning canopy]

where do this statistic come from?

[lost matrix]

bstats

[cunning canopy]

what is bstats?

[lost matrix]

https://bstats.org/

[cunning canopy]

if I understand correctly this is a plugin?

[lost matrix]

Nope. Its a statistics tracking library. People usually shade it into their plugin to track usage.

[cunning canopy]

oh

but

wat about the major pvp servers

It isnt guaranteed that those use bstats?

[vocal cloud]

No, it's just highly likely they use a free plugin that contains bstats within it.

[lost matrix]

No its not guaranteed but very likely. Also people that want to play on big pvp servers will hop onto the handful of established 1.8 pvp servers that are still up.
1.8 is a bubble where everyone thinks that the whole world is playing 1.8 while in reality they are a minority.

[vocal cloud]

It's also tech debt that keeps these servers on those versions. If most were to make a new server today it would undoubtedly be on a much newer version.

[cunning canopy]

ok so I should go for the new version playerbase?

[lost matrix]

Thats up to you but i personally wont ever support older versions. Keep in mind that you also wont get any support here for issues you might run into.
1.8 is very frowned upon in the dev community.

[cunning canopy]

I understand

Will I as easily be able to get in new players?

[eternal oxide]

Depends how good you make your server

[cunning canopy]

ok let me rephrase

as esay

easy

oh nvm

I did say that

ok

but how far back should I support

[eternal oxide]

again, depends on how much you want to struggle. Newer teh API, the better it is

back to 1.16.5 covers about 90% of the player base?

[cunning canopy]

cool

[glossy scroll]

new API is added almost every day

eh, rather every week

[quiet ice]

Myes, but rarely is that new API of use

[last swift]

I’m utilizing Multiverse to have multiple worlds, but upon teleporting the player via player.teleport() and then setting their gamemode to spectator via player.setGamemode(), the player ends up in survival mode since Multiverse sets the player’s gamemode automatically. However, I don’t want to switch the gamemode for the world to spectator since I end up teleporting other players to the world and want their gamemode to be survival. Is it possible to force a player’s gamemode and override it over Multiverse? Hope that makes sense…

[eternal oxide]

manage-gamemodes in Multiverse config I believe

[sterile token]

Doesnt break spigot rules?

🤔

Because the rules said that the plugins should work without ethernet connection

😂

[valid folio]

Hello! I wanted to know if i typed unicode correctly

{"providers":
[
{"type":"bitmap","file":"custom/admin.png", "ascent":7,"height":7,"chars":["ꈁ"]}
{"type":"bitmap","file":"custom/VIP.png", "ascent":7,"height":7,"chars":["ꈁ"]}
]
}

[lost matrix]

Yes. They always talk about the fight club for example.

[sterile token]

They are so fkcing amazing

Becaue spigot break his own rules

Because spigot must use internet to work

🤡

[vocal cloud]

Bstats doesn't make you require an internet connection lmfao.

[sterile token]

How upload the data so?

thru the air?

[vocal cloud]

If it can't it doesn't. Simple

[sterile token]

😬

[lost matrix]

You mean "ꈁ"? This is a valid unicode char. Not sure if the minecraft default font supports it.

[vocal cloud]

Use your brain. If there's no internet it doesn't do anything

Therefore it doesn't require internet

[sterile token]

But im saying what said spigot rules

😂

[valid folio]

No. I spelled it incorrectly when i do this alone {"type":"bitmap","file":"custom/admin.png", "ascent":7,"height":7,"chars":["ꈁ"]} i works, but when i do both of them it doesn't. And yeah i want to know if i done that incorrectly. And how to fix it

[sterile token]

They are so funny lmao

[quiet ice]

This is no place to do stupid jokes

[lost matrix]

You are missing a comma

[quiet ice]

Sure, the website requires internet connection - but this is about plugins

[eternal oxide]

bstats breaks no rules. it fully works without the internet. Its your fault you can't see the website 🙂

[sterile token]

Oh this is not general right?

[quiet ice]

Yes

[sterile token]

My bad

[valid folio]

Can you help me witht that? Cuz i am really raw on that

[sterile token]

Im really dumb

[valid folio]

I have no idea how it works in general

[lost matrix]

This is how a json array looks like:

[ {}, {}, {}, {} ]

[sterile token]

7smile each {} is an object right?

[lost matrix]

[
  {},
  {},
  {}
]

[lost matrix]

yes

[sterile token]

Oh ok

Its more or less similar to yaml

In yaml they are called ConfigSection in json they are just object

[lost matrix]

yaml is a superset of json

[sterile token]

Oh i figure yeah because they are the same

But json uses more characters for saving data

[valid folio]

@lost matrix

{"providers":
[
{"type":"bitmap","file":"custom/VIP.png", "ascent":7,"height":7,"chars":["ꈁ"]},
{"type":"bitmap","file":"custom/VIP.png", "ascent":7,"height":7,"chars":["ꈁ"]},
{"type":"bitmap","file":"custom/VIP.png", "ascent":7,"height":7,"chars":["ꈁ"]}
]
}

[sterile token]

And i think that json is fasther than yaml when came in terms of data savomg

[valid folio]

Is hat right format?

[sterile token]

yes

[valid folio]

Ok i'am really thankfoul

[sterile token]

So you ill have an array "providers" and them 3 objects

No problem if need something else just ask it here

Have a good day

Oh lmao im starting to hate paginated/paged menus

[cunning canopy]

how would I go about letting an arrow pass through an entity

[lost matrix]

This is very tricky because the movement is also computed and extrapolated on the client. So it will look buggy.
First step: Cancelling the ProjectileHitEvent and see where that leads you.

[cunning canopy]

would it be possible to see if an entity was hit by an arrow

and shoot it out with the same velocity?

[lost matrix]

What you can do us listen to the event, cancel it and teleport the arrow forward at the end of the BoundingBox.

Requires some math.

Using the angle and BoundingBox dimensions.

[cunning canopy]

oh

seems like there is a

entity.spigot().setCollidingWithEntitiesFalse

[last swift]

I don't see that in the config sadly. I'll do some research rq tho

[dull whale]

anybody know a good lib for spawning shapes/effects with particles?

"Discord Mod" always comes good. Doesnt have any neckbeardy vibes at all.

[vocal cloud]

Imajin pretending the other helpers don't exist

[quaint mantle]

False.

I dont put myself above everybody

Its just my personality

[ivory sleet]

Hehe

which also does not put my above everybody

You don't need to put yourself above everyone if they don't exist

First of all

args[0] == "1"

Dont compare objects with ==. This will pretty much always be false.
Use .equals() instead

Amazing repo i find

Instead of using build tools for spigot jars

I can use that

[lost matrix]

Not illegal at all

still not working after I edited it

[lost matrix]

Pls paste the full exception as text somewhere. The screenshot is hard to read and it looks like its incomplete

Just distribute mojang code

[sterile token]

I will use it for coding plugins faster, so i skeep the proccess of building every spigot locally and then install it to local repo, etc

[carmine valley]

how do I copy from the console?

[sterile token]

linu or window?

If you are on linux you can copy everything like marking the text and pressing right click

[eternal night]

unless you have it paasword locked that doesn't change it xD

[sterile token]

what pass?

Its public

I mean i can use every artifact from the repo

[eternal night]

So you are publicly distributing code you don't own nor have a licence for ?

what what

And i asking if illegal to use it for coding

🤔

[alpine urchin]

duckduckgo users rn

:c

[eternal night]

Well, the repo itself is not legal to be up

if it distributes mojang code

[alpine urchin]

yeah vague area

[sterile token]

what means redistrubite mojang code

[eternal night]

Well, you can just download the server from there

[alpine urchin]

sharing mojang code

[sterile token]

Because the spigot itself redistrube mojang code

[eternal night]

it does not

that is why you run build tools

[carmine valley]

this is the entire console https://paste.md-5.net/ecopazewow.md

[alpine urchin]

should

[eternal night]

and why you are building the server on your local system

[alpine urchin]

spigot uses mojang server internally to work

[eternal night]

OH LOL

[cunning canopy]

it does not have a cancel method

[alpine urchin]

buildtools downloads mojang code on your pc

[eternal night]

using something != distributing something

[alpine urchin]

and modifies it

[sterile token]

Okay because i have a community with friends and we want to have a private repo with the spigots artifacts all together

[alpine urchin]

ok

[sterile token]

So then we dont depend from 3rd party repos

And also for uploading our custom libs

That my final point

[eternal night]

should not be an issue to have a private repository. Tho also like, just use paperweight userdev 😛

[sterile token]

https://repo.codemc.io/repository/nms

That the repo i find

Can u take a look

Also here is redistributing mojang code 🤔

[sage patio]

light mode burns your eyes

[eternal night]

Yea I know that repo

[sterile token]

yesi cannot change it

It not mine repo

Its also a nexus repo

[eternal night]

Well, don't use it /shrug

[serene onyx]

Light mode gives you wings

[sterile token]

what lynx?

[eternal night]

Well use a proper setup for nms

[sage patio]

and you can fly to heaven because ur dead yes

[sterile token]

More or less i would need a private repo for setting up all our artifacts and spigot, spigot-api, nms etc

[serene onyx]

i was more thinking the redbul commercials but that too

[sterile token]

I dont think that mojang would do something

They are just for the money

[eternal night]

They might not, but respecting their licence is just like

[sterile token]

Imagina if they dont care about pay2win servers

😂

[eternal night]

decent behaviour

[sterile token]

I know happen the same with eula bruh

Most minecraft servers breaks eula rules

And mojang doesnt care that why

We also dont give access to that private repo they only will be used by our custom plugins

And thanks lynx you always answering i really appreciate that

👍

[eternal night]

Yea if it is a private one you should be fine 👍

[sterile token]

Its private but what if we sell a custom src which uses the repo?

I never thought about that

[eternal night]

I mean, as long as the source does not contain the server jar xD

[sterile token]

Oh ok

[eternal night]

coding against it is not the same as distributing it

[carmine valley]

help would be greatly appreciated. Console: https://paste.md-5.net/ecopazewow.md

[sterile token]

Sorry for ignorance but the only way for working with nms is minecraft-server artifact and the spigot?

[lost matrix]

First fix this exception:

java.lang.NullPointerException: Cannot invoke "org.bukkit.entity.Player.getDisplayName()" because the return value of "me.r3dx.mcbrawl.commands.PlayCommand.returnFirstPlayer()" is null

Doesnt get more descriptive than that.

[sterile token]

Because i know that spigot is the "core", which uses spigot-api, minecraft-server

[eternal night]

I mean, paper has a more elegant solution. For spigot yea

[carmine valley]

why is it returning null tho? shouldn't it return p1 which we set after doing /play 1 ?

[buoyant viper]

paperweight-userdev?

[sterile token]

So lyn if do public the repo and only upload the spigot and spigot-api artifacts i wouldnt break rules?

[eternal night]

Yea

Well

spigot includes the entire server

[sterile token]

Hmn yeah that why

[lost matrix]

When the server starts then nobody called this command before. So what do you expect to be in the variable then?

[sterile token]

Its so diff this

Because legal proccess can literally break your mom

😬

[lost matrix]

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[eternal night]

the spigot minecraft mapped jar still contains the entire server

in 1.18

no ?

isn't that how spigot does NMS

[young knoll]

Yes

[eternal night]

yea

[young knoll]

So does the unmapped one

[eternal night]

but yea, spigot just shits them back together

so people don't have to define mojang libs manually

[sterile token]

Col have you read all what we talking ? hehehe

I think its a interestic topic

Maybe i open a thread

[lost matrix]

If you want to use nms with spigot now then you should just use the special sources plugin + the setup presented to you in the forum post.

[sterile token]

Does it apply with any spigot?

[lost matrix]

No. 1.17+

[carmine valley]

how do I fix that tho? before any player executes the command, the scoreoard is not supposed to have any player name

[sterile token]

Oh that why heheh

Allright thanks to all lynx, smile and coll

[lost matrix]

Are you asking me how to fix a simple null pointer exception?

[carmine valley]

just a simple if null then return "" ?

[sterile token]

I will talk to my friends and try to find a solution for this. Because we must need a private repo for hosting all the spigot artifacts because it a mess if not

[lost matrix]

A null check could help.

[sterile token]

also why now yaml warns about nulleale

Its a mess using that spigots

I couldnt find a way to not care them without adding an annot

[unborn kiln]

Is there a way to get the number of enchants on an item in a persons hand?

[sterile token]

Get the itemstack from his hand

[cunning canopy]

is entity.spigot().setCollidesWithEntities(false); still a thing?

[sterile token]

hat version?

Also have you checked if exists in the jd-.s from your version

[cunning canopy]

1.16-1.19

[sterile token]

U will have to check manually on each versions

[cunning canopy]

I cant find it in 1.19

[unborn kiln]

How would I get the amount of enchants on that item with an integer?

[cunning canopy]

does it mean its gone?

[sterile token]

Because maybe exists on 1,19 but not on 1.16

[sterile token]

ItemStack enchantments isnt a collection?

[lost matrix]

You get the map that contains the enchantments and simply call .size() on it

[unborn kiln]

kk, ty

[lost matrix]

Its a method from Player.Spigot

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.Spigot.html#setCollidesWithEntities(boolean)

crunch from @waxen plinth

https://github.com/Redempt/Crunch

[carmine valley]

so I wrote that java if(PlayCommand.returnFirstPlayer().equals(null)){ player1Name = ""; }else{ player1Name = PlayCommand.returnFirstPlayer().getDisplayName(); } if(PlayCommand.returnFirstPlayer().equals(null)){ player2Name = ""; }else{ player2Name = PlayCommand.returnSecondPlayer().getDisplayName(); } but I'm not sure where it should be properly placed

just in my onEnable method?

[cunning canopy]

where can I download spigot 1.19 api

[lost matrix]

Null checks always with ==

[carmine valley]

didn't you tell me to use .equals earlier?

[lost matrix]

All of your variables and methods are at random weird locations already anyways. Just throw it somewhere like the rest.

[carmine valley]

like what? I thought I properly placed all of them

[cunning canopy]

where do I get the api dependencies?

[lost matrix]

Of which api?

[cunning canopy]

spigot

[lost matrix]

What do you mean by "get"?

[cunning canopy]

I mean download

dependencies

[lost matrix]

You should let maven handle pulling transitive dependencies

[cunning canopy]

I am using intellij ideas build artifact thingy

where I downloaded the 1.8 api jar file

for spigot

[buoyant viper]

🙁

[cunning canopy]

so where can I get the 1.19 one

[delicate lynx]

please use maven or gradle

[lost matrix]

You should really use maven instead. The minecraft dev plugin for intellij generates a clean maven spigot project for you.
Otherwise: Run BuildTools and get the uber jar

[cunning canopy]

doesn't IntelliJ idea use maven when building artifacts?

[quaint mantle]

Its its own build system i think

Which of course can use the maven repo

[cunning canopy]

I think it uses ant

after seeing the build logs

that good enough?

[quaint mantle]

Just use maven or gradle 😒

[cunning canopy]

how do I get started with maven?

[quaint mantle]

.

[cunning canopy]

you can get plugins for intellij?!

[quaint mantle]

💀

[cunning canopy]

how

[quaint mantle]

Nah its just a multibillion dollar company that cant develop plugin support for its most popular IDE

[quaint mantle]

CTRL + ALT + S

plugins

Explore

"minecraft dev plugin"

[cunning canopy]

is there any settings I need to alter with when installing

like what next

[quaint mantle]

Nope

Create new project

[cunning canopy]

can I just copy in my old project without changing the structure afterwards?

[quaint mantle]

Sure

[cunning canopy]

how do I build with the new plugin?

[carmine valley]

just the run button

[vocal cloud]

No lol you run mvn package

[quaint mantle]

The run button works

[vocal cloud]

If you've set it up

And don't install

[cunning canopy]

since when is a folder called a package?

[opal juniper]

since forever in java

[quaint mantle]

Forever

[opal juniper]

and other langs

[cunning canopy]

anyway to set it up so that the generated file goes in another "package"?

[sterile token]

By doing artifact set and refactoring i think

You mean for example your project having mongo-driver inside your plugin?

[carmine valley]

can someone please help me with the error I'm getting when I execute my /play 1 command?
Error: https://paste.md-5.net/uduzasanil.cs

Oh uingmaven?

[cunning canopy]

ye

[sterile token]

I have the solution

1 sec

[carmine valley]

so is the error because I'm using 1 and 2?

[sterile token]

is this ok for checking whether my task is done? could there be an issue with a reused task id?

[cunning canopy]

cant you just call a function when the task exits?

[sterile token]

Inside <configuration> tag add this: <outputFile>path/to/folder</outputFile>

[inland axle]

wdym

[delicate lynx]

why on this planet are you using thread sleep

[inland axle]

to put the thread to sleep

[sterile token]

You shouldnt do that

[delicate lynx]

absolutely not

[sterile token]

You can block the main thread

[inland axle]

it's not on the main thread

[cunning canopy]

thanks

[delicate lynx]

use the scheduler

[inland axle]

that sounds like alot of effort

[sterile token]

If you are using the maven-shade-plugin it will generate many jars so you can add path/file-name.jar to only move the output for a specific jar

[delicate lynx]

well if you're not open to trying, good luck!

[inland axle]

I just scheduel things then wait

[sterile token]

GOOD LUCK

If you dont listen is all what we can tel lyou

We are explaning how to do it...

@cunning canopy coould you understand? Sorry for pinging

[inland axle]

arl but good idea to just call a function when task exit

[cunning canopy]

ye

[cunning canopy]

yup

I am new to maven

and have no Idea how pom.xml works

but I think it works

apparently maven is denied access to the folder

any clues?

[inland axle]

did you run it as root earlier?

[cunning canopy]

im on windows...

[sterile token]

Okay i used to have that issue

But some days before started to work

I just ended up that maven was crazy

[cunning canopy]

and the solution is?

[sterile token]

I dont really know

I just leave that shit alone and some days after started to work

Maybe ask here because lot of people here uses maven, then can help you

Sorry matter

[carmine valley]

@sterile token did you take a look at my code?

[sterile token]

I will do it now bro

But be patient

Im a bit bussy

Sfran what are trying to do ?

I dont understand

If you dont want to create with colores remove the .color()

and that all

[delicate lynx]

what the fuck is that code

[sterile token]

Same question man

[inland axle]

The only way I could see this would be some sort of recursive function that scheduled a copy of itself again a few ticks later

[eternal oxide]

ChatColor.RED are teh codes, etc

you want to pull a color code from a string?

[sterile token]

Safran if you want the colored thing just do sout of ItemStack#getDisplayname()

ChatColor#translateAlternativeColors('&', "colored string") ill apply the color

[eternal oxide]

Why do you want the color? are you comparing the string or something?

and you want it to have teh same colour as the item

do you know if the colour code is the first character in the name?

[sterile token]

Sfran

The method name could be wrtten wrong

i just writed by hand on discord

That method i told u

Is usally used to convert the colored text that use this "&4Red text" into the spigot color

[eternal oxide]

try ChatColor.getByChar(Char)

pass in teh first char of the string

name.charAt(0)

this will only work IF the Name has the color code as its first Char. If there is other formatting like bold, it may not be a color char

what is the exact text in the string?

the custom name you are trying to fetch the color from

[sterile token]

Yeah he doesnt explain really well

Or atleast we dont understand what he wants

Either that nor he is trolling us

😂

[eternal oxide]

I understand what he wants but yeah, lackign

[sterile token]

neither me

Im native spanish speaker

[eternal oxide]

if the first Char is not a color code I'm going to guess he's using RGB colors

[sterile token]

Ohh

that why

That is diff

[brave goblet]

Are you using ur server om ur pc or?

[sterile token]

?

Off topic question

hahahah

[brave goblet]

no

[eternal oxide]

pulling an rgb is more code than I have time to explain here right now. Too busy

[brave goblet]

cause then he can just copy the name to clipboard with the hex values or what ever

[sterile token]

Yeah rgb are not simply

[brave goblet]

with the § symbol

[sterile token]

let me find a tuto for using rgb bro

be Patient and wait me

[eternal oxide]

actually its rgb so shoudl be 7 characters?

[sterile token]

https://www.spigotmc.org/threads/hex-color-support-and-legacy-support.452106/

I finx that tuto

[eternal oxide]

yes but there is a control code

so 7 or 8, I forget

lets say 7

so Chatcolor.of(first 7 characters from name)

[sterile token]

public static String translate(String message) {
  if (FlameChat.getServerVersion() >= 16) {
    Pattern pattern = Pattern.compile("#[a-fA-F0-9]{6}");
    Matcher matcher = pattern.matcher(message);
    while (matcher.find()) {
      String color = message.substring(matcher.start(), matcher.end());
      message = message.replace(color, ChatColor.of(color) + "");
      matcher = pattern.matcher(message);
    }
  }
  return ChatColor.translateAlternateColorCodes('&', message);
}```

I find that also

[eternal oxide]

yep 7 chars

[sterile token]

Elegar is that okay?

I find that for him

[quaint mantle]

Hi :D I have a world creator plugin but i wanna make permissions. That means if e.g. player creates a new world, then the player who createt the world will be given the permission world.owner and he can delete it and so on. But how do i do that. I have to use for() or smth like that and save every players permissions IN EVERY WORLD in the config. I know im overcomplicating this(i hope i do so xd) so do you guys have any suggestions? Thanks :P

[eternal oxide]

that shoudl give him enough to work from

it uses regex, all he needs is to get the first match

[sterile token]

Hmn i dont still what he wants....

😂

I dont know if want to translate the hex into ChatColors

Or what the heck

[eternal oxide]

he's trying to pull an RGB code from the custom name of an Item

he wants the md5 ChatColor.of(7 char rgb color pulled from Item Name)

[quaint mantle]

Hi D I have a world creator plugin but i

[eternal oxide]

yes

[sterile token]

Hmnn still confuse i think rgb are not for me

neither hex

[eternal oxide]

you need the first 7 chars of your String

[sterile token]

He need regex for that

I understand know elgar

[eternal oxide]

ChatColor.of(name.subString(0,6)) I forget how to use substring without looking it up

Yes, your color is an RGB

[quaint mantle]

?

[eternal oxide]

it takes up 7 Characters in teh name

You only see a color once displayed

but its 7 characters long defining it

[quaint mantle]

any one know?

or help

pls

[eternal oxide]

Yeas, again it has a control character to indicate its an RGB

so like #ababed

[quaint mantle]

oh wow thanks for ignoring me

:D

bitch

[vocal cloud]

You're welcome

[eternal oxide]

kinda busy... bitch

[vocal cloud]

[twilit wharf]

I am getting this super weird error when opening a gui, I am using a wrapper btw (RedLib)

https://paste.helpch.at/izoyapofuz.cs

[wicked remnant]

Am i correct in understanding that 1.8.8 used gson 2.3.1?

[eternal oxide]

Read thsi and see if you understand it. I'm busy with my wife at mo so can;t help further. https://www.spigotmc.org/threads/detect-hex-colors-and-apply-them.448771/

[vocal cloud]

It appears you're calling a method with itself or something that's creating infinite recursion

[twilit wharf]

here is the code if you wanna take a look, I didnt find anything on my own

https://paste.helpch.at/upaceposoh.cs

I know where the issue is coming from

[vocal cloud]

The error in there mentions get first available plot or something

[twilit wharf]

yeah

[vocal cloud]

Check for recursion because obviously it's calling itself somewhere

[twilit wharf]

yeah, the first available plot method ran a System.out.println for debugging which is where the error ended

[vocal cloud]

Well what's choose plot line 97?

[twilit wharf]

menu.open(player);

ok so

I figured out

where everything goes wrong

so

when the player clicks on a item in the inv, it closes the inv, then loads their plot. When they close the inventory, the plugin checks to see if they have a plot loaded, if not reopen the menu

[sterile token]

Mike do u have experience with paginated menus

Im really exaust lmao

I cannot even see paginated/paged menus

Because they are really to deal with them or atleast for me

[vocal cloud]

Yes, there are libs if it's too difficult for you.

Guava has some great methods for splitting arrays into pages and then you just need to add the indexing system if you want to do it yourself

[sterile token]

I think i dont understand how they works

[carmine valley]

hi guys, whenever I try to build my project it tells me that one of the packages I imported (JAR) does not exist even though I imported it to my project

how can I fix that?

[lost matrix]

All you do is define a number of items per page (N) and then go through your content.
So from 0 -> N then N + 1 -> 2N then 2N + 1 -> 3N and so on...

[lost matrix]

What ide and which build system?

[azure hawk]

how can i make it so that e.g. when i make a command and execute it, and then like a message comes up with "Do you realla wanna do this [Y/N]" and then you can type in chat y or n and if you dont type that in like 10 secs the process is beeing cancelled

[carmine valley]

Intellji, just a jar file

[eternal night]

[cunning canopy]

I used minecraft dev plugin in IntelliJ to setup my plugin project. Is there any way to change the path that the jar file will be put in?

[lost matrix]

Spigot has a conversation api for this. You could also do something with the AsyncPlayerChatEvent, a map/set and a runnable that removes the entry.

[lost matrix]

Well. Make sure your dependencies are correct then. Not much we can help with.

[carmine valley]

dude, I'm not using maven

literally just a jar file that I specified the path to

[lost matrix]

As you clearly stated

[lost matrix]

Then make sure you "literally" specified the appropriate dependencies.

[azure hawk]

Can you simplify that xd Im learning java at the moment and dont quite understand what you mean

[carmine valley]

I did

no errors until I hit run

[sterile token]

I just dont know how to implement it to actual menu api that why. So that the way how i create normal menus. Now im over and over thinking how do to the paginated way

[lost matrix]

Then build your artifact. If your IDE has no problems with your imports then everything should be fine.

[vocal cloud]

If you're not using someone's library you really want to write a utility class for it.

[lost matrix]

This is not a trivial task. Do you know what a HashMap is?

[lost matrix]

Do some research and come back when you know at least

• what an instance is
• what a Set (specifically HashSet) is

[cunning canopy]

I used minecraft dev plugin in IntelliJ to setup my plugin project. Is there any way to change the path that the jar file will be put in?

[sterile token]

I already told you

[cunning canopy]

it did not work

[sterile token]

Using maven you can set the output file route

[shadow night]

Is there some kind of list with all items?

[sterile token]

You have an enum called Material which contains all items

[lost matrix]

With maven? I would configure the maven shade plugin.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>

[azure hawk]

Then i know it already but ok

[sterile token]

I sent the same code

But it said that he doesnt have permissions

It used to happen to me but i leave the error alone and days after test it again. And it was fixxed

😂

[cunning canopy]

can the output dir be outside of the project folder?

[sterile token]

Yes

[vocal cloud]

Not the best idea to do it that way but it can be done.

[sterile token]

hat about for putting it on a local server? 🤔

😬

[hot wolf]

The InventoryCloseEvent also gets triggered when a player dies, is there a way to tell if that was the reason for closing the inventory?

[vocal cloud]

You can always move it.

[sterile token]

So why you said its not okay doing that....

Also mike its really painful deadling with paged menus i didnt thought it was so painfull

[lost matrix]

The close event is fired before the death event (iirc). So the only way i can think of is checking if the players health is 0

[hot wolf]

kk, thx

[vocal cloud]

Use a library then.

[sterile token]

You wanna me get more illnesses

The library feels me really ugly

[vocal cloud]

Write your own library

[sterile token]

What im doing hahaha

[lost matrix]

Maven is not meant for continuous integration. The clean way would be to use jenkins or a script.

[sterile token]

Okay

[vocal cloud]

If the server gets moved or deleted it'd be a pain to get it back, not to mention building a release

[sterile token]

I dont know i just use the outputfile to not to chnage the intellij screen open the server and doing that ass-ole things

[vocal cloud]

Honestly I'd just use Gradle and setup tasks to automatically run it on a server for me.

[sterile token]

Gradle != Maven ==><==

[vocal cloud]

Gradle > maven

[sterile token]

I dont think

In terms of compilations i dont agree

It take more time for doing simple compiling phases

[lost matrix]

In theory you can also use the surefire plugin and write java code that gets executed

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.2</version>
    <configuration>
        <includes>
            <include>SomeCustomTask.java</include>
        </includes>
    </configuration>
</plugin>

[lost matrix]

Yeah when caching. But the first build can take ages.

[vocal cloud]

For smaller projects yes.

I'm just saying that if you want to do crazy stuff like copying hoo-ha's around the best method would be using Gradle. Performance isn't as important to me atm.

[lost matrix]

We should all just use ant

[cunning canopy]

I used to

until you guys said use maven

[vocal cloud]

Maven is fine.

[lost matrix]

Never met someone that actually still uses ant

As in when it shows up on message? That's a client thing isn't it?

its a server.properties option iirc

idk

might go both ways

[mighty aurora]

Quick question. So I was looking at the spigot wiki(I'm working on learning to make as well as making plugins) and I was looking at the code on the GUI page(https://www.spigotmc.org/wiki/creating-a-gui-inventory/) and I noticed that in the section of code that is the call to open the GUI he uses ent

        ent.openInventory(inv);
    }```  I was wondering what the ent means?

[buoyant viper]

entity

HumanEntity

specifically

[lost matrix]

its the name of the variable that gets passed to this method. Could as well be catWithAHat43

[quaint mantle]

Sorry if this is a weird question but I've just been trying to find a friend who's decent at coding who is available to call sometimes and help me code some simple stuff. I'm making a server that is really important for a certain community because something really dumb happened on the server the community was using and now it's unusable. The server is so important that I decided to learn coding and create a replica of the specific function the server has that I was using. It's going well but there's like one or two parts I need help with but I can't really use a tutorial and I also would like to understand coding more by calling with 1 on 1 help so I can improve the server more. I know no one knows me but if anyone wants to help out some random dude I would really appreciate it

[eternal oxide]

What is the "community"?

[quaint mantle]

Hypixel parkour speedrunning

[lost matrix]

version?

[quaint mantle]

I'm coding using 1.8.8 since I use 1.8.9 to do parkour

I want the server to be for all versions

[eternal oxide]

You are going to be very out of luck

[quaint mantle]

Preferrably

[eternal oxide]

General questions and help we can give, but nothing 1.8 specific as our answers are almost guaranteed to require a more modern API.

[quaint mantle]

Well I just want a friend

[sterile token]

is possible to convert that into a lambda exprension

[lost matrix]

that is a lambda expression

[sterile token]

lambda isnt the one that uses for example Player::getName ?

[hybrid spoke]

no lambda is ->

I mean thats method reference lambda

[quaint mantle]

.

[sterile token]

Oh ok

lambda expressions uses the "->" okay

I thought that lamda was when you use that what i sent on top

My mistake i get mixed

Oh lmao im messed with paged menus

I still cannot do atleast 1 simply but functional code

[zinc sedge]

how can i kick a player after is totem was used?

  @EventHandler
    public static void EntityResurrectEvent(EntityDeathEvent event) throws InterruptedException {
        if (event.getEntityType().equals(EntityType.PLAYER)) {
            if (!event.isCancelled()) {
                if (AfkCMD.isAfk.contains(event.getEntity().getUniqueId())) {
                    Player player = (Player) event.getEntity();
                    TextComponent tc = Config.tc;
                    tc = tc.append(Component.text("AFK-Schutz wurde aktiviert!", NamedTextColor.RED));
                }
            }
        }
    }

this is my code rn, but it just kicks the player before the totem gets activated

[sterile token]

I would map the player uuid and them a boolean

[zinc sedge]

but that doesn't change anything does it?, i mean my code kicks the player i want it to kick but like too early

[sterile token]

You kick the player before or after?

Or what is your issue exact?

[tranquil dome]

Is there a way to get which enchantment is shown in the enchantment table preview or to get the enchantments that were added as a bonus after enchanting?

[sterile token]

You can do what i told so when he use the token add to map with boolean true, and then on respawn check if contains the uuid and kick it

🤔

[full forge]

put a delay before you kick

[lost matrix]

A Map<T, Boolean> is in almost all cases useless. Use a Set<T> instead

[sterile token]

Why a type generic?

[zinc sedge]

does a totem trigger the respawn event?

[quaint mantle]

Bruh

[sterile token]

Map<UUID, Boolean> its even more simply

[river oracle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityResurrectEvent.html take a look at this

[lost matrix]

@zinc sedge, if its kicking your player too early then delay the task :thinksmart:

[tranquil dome]

I looked at those, but couldn't really find anything. The getEnchantmentBonus method returns an int, not the actual enchants added ontop of the original enchant. And I cant find anything that can get me the original enchant (see picture) https://prnt.sc/kTSlBrJUboB0

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/enchantment/PrepareItemEnchantEvent.html#getOffers()

[noble lantern]

You would just have to store the list of enchantments before and after enchanting - (removing) the expected enchantment from the list

[tranquil dome]

The method does not exist in 1.8.8. If I were to make the plugin in a more recent version, would it still work on 1.8 spigot servers?

[lost matrix]

Thankfully not

[lost matrix]

1.8 is ancient. Support was dropped years ago and the player base is vanishingly small. Nobody should write plugins for that version anymore.

[hollow tinsel]

in a lifesteal plugin i payed for there is a bug where when you relog to the server it resets your health to full and im wondering if anyone could help me fix it, i think its 1 of 3 codes

@EventHandler
public void onRespawn(PlayerRespawnEvent e) {
setPlayerHealth(e.getPlayer(), getPlayerHealth(e.getPlayer()));
if (getPlayerHealth(e.getPlayer()) == 0)
setPlayerHealth(e.getPlayer(), 20);

or

public void setPlayerHealth(Player p, int h) {
p.getPersistentDataContainer().set(this.Life, PersistentDataType.INTEGER, Integer.valueOf(h));
p.getAttribute(Attribute.GENERIC_MAX_HEALTH).setBaseValue(h);
p.setHealth(h);

or

public void setPlayerHealthNoUpdate(Player p, int h) {
    p.getPersistentDataContainer().set(this.Life, PersistentDataType.INTEGER, Integer.valueOf(h));
    p.getAttribute(Attribute.GENERIC_MAX_HEALTH).setBaseValue(h);
}

[lost matrix]

Do you have a listener for the PlayerJoinEvent?

[hollow tinsel]

if im going to be honest, i dont know how to code plugins all i did is download eclipse and im looking through to see if i could fine it, i have the source code but have no clue how to check sorry lol

if (getPlayerHealth(e.getPlayer()) <= 0) {
setPlayerHealthNoUpdate(e.getPlayer(), 8);
return;
}
setPlayerHealth(e.getPlayer(), getPlayerHealth(e.getPlayer()));
} else {
setPlayerHealthNoUpdate(e.getPlayer(), (int)e.getPlayer().getAttribute(Attribute.GENERIC_MAX_HEALTH).getValue());

[delicate lynx]

look in your plugin's main class

[hollow tinsel]

all thats in the main class is the recipes and items

[lost matrix]

The main class is irrelevant. All you need is right there in the join event

[hollow tinsel]

} else {
setPlayerHealthNoUpdate(e.getPlayer(), (int)e.getPlayer().getAttribute(Attribute.GENERIC_MAX_HEALTH).getValue());

is it this?

if i remove that?

it looks like its overriding the getplayerhealth

[rare flicker]

I've been peeking around at enchantments and stumbled upon this

anyone has any idea what they mean by "start at"?

[tender shard]

IIRC it's always 1

[flat leaf]

anyone here have any idea why the worldedit API wouldn't be giving me the correct blockdata when retrieving a block from a loaded clipboard (that was loaded from a schematic)?

on 1.19, using world edit beta 7.2.11-beta-01 on the server and API version 7.3.0

if I paste the schematic in game things like chests have the correct items, but getting the BlockState using the API doesn't have the same outcome

[tender shard]

weird, but you're probably better off asking on their discord. IIRC they have a discord

[flat leaf]

I wonder if maybe the block entity is counted as an entity

alright yeah I'll head over there, thanks

[twilit wharf]

I am getting these weird errors. I believe it is because of recursion. I just cant seem to find where the incursion is happening. Here is the code: https://paste.helpch.at/junoyirure.coffeescript (no clue why it is coffeescript) and here is the error: https://paste.helpch.at/emiyizeveb.cs

I am using a wrapper for GUIS btw (RedLib)

[vocal cloud]

Yes as I said before the issue is right here.

You map the line -> code and figure out what line is giving the error.

I bet if you add some simple logging this issue will be over very fast.

[worldly ingot]

My goodness that's a lot to be doing in a constructor

[vocal cloud]

Indeed

[buoyant viper]

[worldly ingot]

Seems like a misuse of a constructor tbqh. That could definitely be a static utility method at least

[vocal cloud]

Also when pasting code please include everything (Ctrl+a) so we can match errors to lines

[twilit wharf]

oh yeah, my bad

I found the fix, it was super weird. Thanks for you help

[vocal cloud]

[wet breach]

I think it is worded wrong because really what it means is the minimum level. However, depending on settings or what gets modified, the minimum level can be different then 1. For the most part however, you are correct

[tender shard]

hmm maybe I misunderstood it lol

I always thought it returns the value that's the "min level" for this enchantment

and IIRC there's none that doesn't start at 1

but no idea lol

[wet breach]

assuming defaults

however, if something changes the starting level of an echanment, then it wouldn't necessarily be 1 anymore

[tender shard]

true

I just wonder who'd say "the minimum level for my custom enchantment is 2", that doesnt really make sense

[wet breach]

that is what I meant, is that it should be named as minimumLevel, and not starting level lol

[tender shard]

yeah that would make more sense

[wet breach]

Since there is a method for maxLevel, but no EndLevel 😛

[quaint mantle]

[uncut cobalt]

I got a question about guis, is there a way to customize the way guis appear?

[noble lantern]

What would be a good & simple way to authenticate communication between 2 servers?

I have a proxy server with a few other servers that hooked into it via websocket connection

Rn i just have UUID as the server ID and then a passphrase (encrypted ofc) on both ends as well as IP verification (IE if the connecting IP mismatches a configs IP for that server it disallows the connection), i assume this would likely be good enough? Or is there some standard way this is done

[noble lantern]

explain

Theres afew things that come to mind when you say that

[uncut cobalt]

Like you can create a gui such as the inventory of a player, a chest, a beacon, etc

Is it possible to create a totally new GUI that Minecraft does not have

[noble lantern]

Not without forge no

[uncut cobalt]

like edit the buttons and appearance

[noble lantern]

You are stuck to the InventoryType enum types

[uncut cobalt]

Ah rip

Thanks though :)

[noble lantern]

However

There is soemthing you can do to replicate it

[uncut cobalt]

How?

[noble lantern]

There is a way to make images appear in a GUI

IDK the way to do it, im sure google knows though

but ive seem some pretty crazy stuff with it

[inland axle]

this might be very prone to dos attacks, but you could use symmetric encryption keys

[buoyant viper]

ofc

[uncut cobalt]

Ah okay thanks

[noble lantern]

What would be prone to dos, what i have rn or symmetric encryption

I do have rate limiting both in code and through cloudfare

[wet breach]

ip verification is unreliable

[noble lantern]

Indeed it is, but still is nice to have even though i know it can be faked somehow

Its just what i came up with rn

I was thinking maybe some ssh key type thing but im not sure how tf thats done

So i was thinking just a static encrypted keyphrase would be fine enough maybe

[inland axle]

if there is no ip ban after a attacker sends a faulty packet the server may waste alot of power decrypting junk

[noble lantern]

i dont decyt no need to

decrypt*

I cache the encrypted passphrase for the server rn on startup

[inland axle]

wdym

[noble lantern]

sec lemme explain

On start

• run through config.json on proxy (Contains server UUID, allowed IP, and raw string passphrase)

• Encrypt pasphrase with a public encryption key shared between both servers (The sending server will encrypt the password for the proxy)

From there server 1 connects to proxy, and then the proxy checks the config.json encrypted passphrase against the provided one

[inland axle]

well the server1 would need to know the public key ahead of time

or you would need to use a certificate

[noble lantern]

Yes they both know the encryption key

its not even rly needed i just didnt wanna send the passphrase in raw text

The only thing server1 doesnt know is the password

which the proxy knows

[noble lantern]

Never used them before, i assume its similar to a JWT Token in a sense? Or a lets encrypt ssl cert?

[inland axle]

yeah

what they use for https

but if you can just upload a public key it's alot less hassle

[inland axle]

if server1 was an attacker they wouldn't know?

but if they are legit they will know?

[noble lantern]

Well i already am gonna be using ssl for my websockets

Rn theyre just running in ws (http) instead of wss but once i setup with SSL, i guess i could borrow the priv key from ssl and use that?

[noble lantern]

Yes only way to bypass my current system is to endlessly crack the password

I know pterodactyl just uses a token system to link between daemon and theyre containers, thats why i setup what i have rn

The servers are only ever going to be hosted by me

[inland axle]

I think they use the token to make a symetric key

[noble lantern]

i just wanted to prevent someone from reverse engineering my proxy and gaining access to the game servers, as the CLI will be used to manage certain aspects of it

[noble lantern]

Not sure, idk how theyre code works past 0.7 since they switched theyre code up to Go

[wet breach]

use certs

you can issue certs to each of the servers that connect to the proxy

if the server doesn't present a valid cert, then its not one of your servers

[noble lantern]

By chance is there any lib or native way in java to handle those certs?

i see

CertificateFactory

and

X509Certificate

[wet breach]

yes

you can issue certs like you would unique passwords too

[noble lantern]

for passwords i kinda just create and set them in config files on both servers

[wet breach]

so like each user can have their own cert, all derived from the key on the proxy 🙂

[noble lantern]

i assume i would do the same with cert? just manually give them to the servers i need?

Actually i can setup a linking system where i use a cli to create a server, and on first connection it send the cert that way

i think that may be a lot nicer

[wet breach]

Well wouldn't want to do that, otherwise anyone who connects gets a cert 😛

[inland axle]

lol

[noble lantern]

well it woul be a setup command in cli

and it only allows new connections for linking within a few seconds

and it will send a UUID and ask for linking confirmation

if uuid doesnt match the servers uuid dont issue cert

[inland axle]

if you trust all servers completely symetric is still fastest

[wet breach]

I still wouldn't issue certs like that. That is similar to how WPS works and the reason it is flawed

[noble lantern]

So just manually assign them then after creation?

[inland axle]

how many nodes are you handling?

[noble lantern]

Depends

it will be 1-3 at the start

can be 50-100 in a few years time

They handle individualized game servers, the proxy allows safe communication between 2 game servers (If i manually connected them without the proxy, the networking would become a giagantic web and hard to manage, then proxy handes requests like server1 sends message to server2, and the two are never connected to each other) as well as easy admin interaction

im gonna look into creating certs in java rn

[wet breach]

pretty much the best way to do it

this guarantees that the server you setup, is the one that you want authorized. While although the odds of someone trying to infiltrate your network setup, never hurts to be secure anyways 😛

[noble lantern]

Yeah i doubt anyone will ever even find this IP to this server but i just wanted to be safe

cause if proxy gets accessed all servers are at risk

[wet breach]

well someone will find it, all ip addresses are public

[noble lantern]

Yeah but chances of them knowing what its for are slim

[wet breach]

its just a matter of who manages to scan it first. But I was saying more or less someone trying to actually spoof being an mc server on your network lmao

[noble lantern]

ohhh

[wet breach]

unless this is some other kind of setup

what I said would still be true in a way, and they would have basically have to wait at the right time where you were setting a server up to attempt such things with what you were wanting to do

[noble lantern]

and they would have to know the UUID

becuas eonce it connects there would be a message

"Server with <uuid> is attempting to link, accept linking and send cert (Y/N)"

so theyde have to know the new servers UUID (Which is normally created seconds before sending linking requests)

but imm just do manual

[wet breach]

just use host key fingerprint

[inland axle]

someone could do a mitm attack unless the connection does like a tls/ssl hanshake during setup

[noble lantern]

yeah its a handshake

It connects and directly sends the request when the socket opens, in facts its actually the opening connection message

Basically the flow would be:

On proxy (Server ID is the user friendly string of the server, basically just its name)

server create -serverid 5 -passphrase/cert cert -server_ip 192.168.0.1

And from there it will allow new connections and send

Now accepting new connections for 15 seconds, please start the game server you are wanting to link

On game server -> java -jar server.jar -> Auto connects to proxy on startup and sends its uuid (Will use HKF like frost said i like that idea better)

After the game server connects, on proxy:

Received a connection from 192.168.0.1 and it is identifying itself as <fingerprint/uuid>. Should this link be accepted, and a new cert signed for this machine?

When the game server restarts its connection it will then send the cert it was issues as authentication

I honestly dont think anyone would be able to MIT this as it would happen in mere seconds, someone would need to know the game servers hkf/uuid, as well as the game servers IP addres and be able to fool a manual review of the link

unless im dumb and dont know how web security works

(Might be the case ^)

[inland axle]

when a connection leaves the local network you should assume it has been attacked with a mitm attack

[lethal ermine]

I downloaded a source code of a plugin and loaded it on intelliJ idea and built it with gradle config but I cant find the build for some reason!

[noble lantern]

Connection wont ever leave until receiving server received its cert

RN Actually yes but in the future, i may need to run more game servers on another vps

My current configuration uses 2 IPs IP1 is used for my auth and proxy ip 2 is for game servers (They run on port increments of +1)

[inland axle]

client server starts ssl/tls connection with server (the servers certificate is known to the client ahead of time)
client requests a certificate (it gives a random uuid to the server )
request is displayed on the server with the uuid
request is accepted
certificate is sent to the client
