Not like your isn't gonna be a abonded after you finish it

[drifting viper]

-_

so when you all say that there are already great rust mc servers out there, Why no one uses them and Spigot/Paper is still the Standard

[blazing ocean]

they're feature incomplete

have no support

are experimental

etc

[shadow night]

Because they're reimplementations and incomplete, spigot is just an extension over the official server software and behaves mostly like an official server

[grim ice]

there's no reason to use them

[shadow night]

spigot is the standard, nobody is brave enough to go and change it

[blazing ocean]

i wanna hear lynx opinion on this

[drifting viper]

yeah most of them are build with the goal of incompletion, So you have to only enable what you need like in valence, Most people dont like this approche and don't want to build everything them self

[grim ice]

I don't see how you can disagree with that though

[shadow night]

Most people don't know and don't care about server reimplementations and use spigot or paper

[grim ice]

ig you could say paper?

[blazing ocean]

he's a paper dev yea

[grim ice]

paper is the dominant server software, that's for sure

I can't recall the last time I ran /version and the server wasn't paper

[shadow night]

Iirc ~60% of servers use paper

[drifting viper]

Performance, Security, Scalability. I think you already know the Performance issues of normal Java Servers. The Rust Server can startup in under 1ms. Also important for Large Server to minimize down time and get a good performance with large player count. The Paper team tries to this by Creating Folia.

also uses less resources

[quiet ice]

Minestom is great if you want something different

[shadow night]

And yet you don't see anybody use folia, do you?

[wet breach]

security?

[grim ice]

I can't imagine many scenarios in which 1ms startup is that important

sure it sounds amazing

[wet breach]

in regards to servers, start up times are not really relevant

[eternal night]

[grim ice]

but most of the time you won't be starting up your servers every minute

[drifting viper]

imagine, minigames server or privat player servers

[young knoll]

Wait we need the thing

[wet breach]

I rarely restarted my MC servers

[quiet ice]

The Rust Server can startup in under 1ms. Also important for Large Server to minimize down time and get a good performance with large player count. The Paper team tries to this by Creating Folia.

Have you heard about GraalVM's native-image?

[wet breach]

they would stay up for 30 days or more at a time

[drifting viper]

CloudNet is also there for a reason

[wet breach]

so why would I care about a 10 minute startup time when 99% of the rest of that time its always on

[shadow night]

Some unofficial reimplementation of the server can take ages to update to update to a newer version, while official software gets updated with the release of a new version

[grim ice]

you can get plenty of performance with java

[young knoll]

[wet breach]

still waiting on the security part

not entirely sure what they mean by that

[hazy parrot]

I may not follow exact conversation, but how will mc server written in rust help scalability ?

[grim ice]

how is the coding language going to make your server software more secure?

[eternal night]

Well, you see, with c you could easilyl fuck up and have people uh, like, uh

well yea the server is in java but ehm

[drifting viper]

rust makes it easy to prevent the loved nullpointerreference errors

for example

[eternal night]

that isn't security?

[quiet ice]

Security under Java will probably be better tbh - there isn't all that much you can f up aside from path traversal attacks but that can be easily mitigated and is a non-issue

[wet breach]

that isn't security

[quiet ice]

So does Java

[drifting viper]

this could crash your server more easier

[eternal night]

That is still not security

That is stability at best.

[quiet ice]

Crashing is a non-issue in the grand scheme of things

[drifting viper]

so whats security for you ?

[wet breach]

Java actually does a pretty good job when compiling to let you know about Nulls and a decent IDE would let you know before compiling

[shadow night]

Rust server reimplementations have a major downside of being just not exactly like the original server implementation, which by itself could cause quite a lot to break

[grim ice]

not security, and unless your devs don't know how to handle NPEs idk how that can be a major issue

[drifting viper]

you don't always know them these error can accour

for example an command could crash your server

[grim ice]

Not being easily exploited?

[eternal night]

I'd call security to be the safety of server data and server hardware. Log4J was a security exploit. You crashing a server isn't really. Not that NPEs are common in the first place

[young knoll]

Does hypixel use rust

Kek

[quiet ice]

Commands are handled async so the server by default gracefully recovers here

[wet breach]

security has to do with in memory tampering and whether or not the language detects that. Catching or preventing buffer overflows or underflows

[quiet ice]

The only time when comparing with hypixel is actually useful

[hazy parrot]

What is buffer underflow

[eternal night]

gonna send me a nice msg command to get some ACE going on papermc

[wet breach]

going the opposite way of what a overflow does

so an overflow makes it reset going higher

underflow goes in the other direction

[eternal night]

Certainly possible in java

[shadow night]

There are two choices:
A. Use a patched version of the official server both of which (original and patched) update almost immediately after a new version and have been tested by time, existing for more than ten years
or
B. Some random persons reimplementation of the server in rust that hasn't been tested by a single person

[young knoll]

Pfft comparing to hypixel is always useful

[quiet ice]

basically an array access with a negative index

[young knoll]

Doesn’t that just underflow to the highest possible stack pointer

Or does it start trying to reference whatever is before the stack

[eternal night]

[young knoll]

What

[drifting viper]

So for you buffer overflows or underflows = security issue.
but nullpointerreference = yeah its fine ?

[young knoll]

I mean, accessing memory you aren’t supposed to is a bit of an issue

[quiet ice]

It's absolutely fine in java land

[eternal night]

Well one is a crash of the JVM, the other may allow you to actually run some malicious code

In c at least

[quiet ice]

In the kernel that might be another issue

[young knoll]

Scary red text in console is just whatever

[wet breach]

overflow is accessing memory beyond the end of the buffer. Underflow is accessing memory before the beginning of the buffer. It is more common to happen in caching for example of a underflow happening

[eternal night]

Java is so far away from that issue, it does not matter

[young knoll]

I guess it depends on how the stack pointer is stored

If it’s unsigned it would wrap back to the top

[wet breach]

no this wouldn't happen

the memory address of a negative that is beyond what is allowed would end up being a completely different memory address

and does not wrap back

[shadow night]

I wish java had unsigned numbers

[young knoll]

The stack on the NES wrapped back :p

[quiet ice]

char

[paper viper]

Lmao

[young knoll]

char doesn’t count

hush

[shadow night]

but I still can't unsign a long

[young knoll]

ulong

Or should it be unsigned long for maximum verbosity

[quiet ice]

Well I'd rather have 128-bit CAS than unsigned numbers

[young knoll]

long long

[paper viper]

u could use a lib that makes a fake unsigned type lol

[young knoll]

Let’s make a language where each o added to the word long is another 8 bits

[shadow night]

unsigned long long long

[paper viper]

backs it up with a larger signed type

[shadow night]

thought of that before

just use BigNumber at that point

[young knoll]

long is 64 bits
loong is 72 bits
looong is 80 bits

[shadow night]

loooooooooong

[quiet ice]

Wasn't there a language that supported 0-bit ints?

[shadow night]

so, 0?

[wet breach]

if you ran build tools, all the decompiled classes should be in the work directory

[young knoll]

Run buildtools and then look into the work directory for the decompiled source

[quiet ice]

yes

[shadow night]

actually, 1-bit ints would be great

[grim ice]

are cpu processes ran LIFO?

[paper viper]

boolean?

[shadow night]

yes

[quiet ice]

define processes

[tardy delta]

that would result in a very poor scheduler

[slender elbow]

uhh buffer underflow just means that whatever is reading a buffer is reading more bytes than the writer wrote, and that can still be within the bounds of the buffer, e.g. i have a 128 bytes buffer, i write 32 bytes and you try to read 64 bytes, that's "legal" but that's a buffer underflow or underrun; not that it can't be a security issue tho

[grim ice]

all processes except system ones

since it doesnt make sense for system processes to be ran like that

[sweet pike]

right okay, got it. any way to see that in Mojang mappings? do i just enable that flag when running and the latest decompile folder will update with the mappings?

or is that not possible

[young knoll]

Yes

[tardy delta]

why would processes be run lifo?

[quiet ice]

Uh, obviously no - since otherwise a 4 Core CPU would instantly freeze the system when trying to run more than 4 applications at the same time

[eternal oxide]

should be no security issue as teh SP just goes to zero

[grim ice]

fair

[grim ice]

i have no idea

[quiet ice]

only with malloc'd memory though, no?

[tardy delta]

stack pointer goes to zero?

[eternal oxide]

ie, base of the stack. It can;t go below

[young knoll]

Wouldn’t that depend on the language

[tardy delta]

why would that happen on a buffer underflow

im confused

[grim ice]

i mean what is it supposed to do?

crash?

[sweet pike]

if i do that, is it just the work folder that has the moj mappings? or can i work with them in my CB directory as well?

[young knoll]

Just the work folder

[blazing ocean]

ah coll fucky ou

that's my gif 😡

[young knoll]

The cb code is like

[tardy delta]

ah in the way that you read over the whole buffer and start reading from the stack

[young knoll]

Half mojmap half spigot map half ???

Yes I realize that’s 3 halfs

[tardy delta]

i get it

[sweet pike]

😬

i'm having such a headache trying to navigate all that's required to contribute

anyway, thanks!

[wet breach]

right it can also occur if the rate at which bytes being written is slower then what is being read

[rough drift]

comparing to hypixel is a great tutorial on how to start good and continue not so good

[young knoll]

How many online players do you have

¯_(ツ)_/¯

[blazing ocean]

37531 at least :cope:

for context i did /reload confirm with my plugin on the server

[slender elbow]

i can confidently say that isn't a spigot issue 🤓

[eternal night]

how do you know emily?

[sullen belfry]

lol

true

[slender elbow]

i have a hunch

[sullen belfry]

my bad

[eternal night]

there is an open issue on the paper github for that ^ but yea, not the right discord

[slender elbow]

true

[eternal night]

ah too late

[sullen belfry]

ah okay so nothing to worry about?

not my code doing a freaky time?

[eternal night]

nah

[remote swallow]

@eternal night what did you break

[blazing ocean]

smh lynx

[eternal night]

[lost matrix]

There you go. How about you absolutely never do that again.

[sullen belfry]

why you hating on /reload confirm so much

[lost matrix]

Read the message displayed when you try to reload. Then youll know.

[sullen belfry]

but why give the option then?

[lost matrix]

Its an artifact from the past

[blazing ocean]

why cant i type /core

[sullen belfry]

the funniest error ever

[blazing ocean]

i mean i've encountered those issues before

[lost matrix]

Be more specific. The answer to "why cant i type /core" could be "maybe your keyboard is broken".

Phrase it like this:

I expect X to happen
In actuality Y happens
Here is my implementation, what could be the cause:

[grim ice]

const? as in the dude from event alerts?

[drifting bluff]

yes

[drifting bluff]

i gave myself perms too and like i doesnt work, i cant type /core it doesnt exist and the perms doesnt exist too. like even tho i did everythiing right ?

[drifting bluff]

wait what u doing here lol

[grim ice]

yourpackageshouldlooklikethisbtw, AndYourClassLikeThis

[grim ice]

ive been here for years 😭

[lost matrix]

Alright, since you dont want to provide any more info we'll go about this in a heuristic way...
Type in /pl is your plugin enabled?

[drifting bluff]

yes

[drifting bluff]

what more info i gave u code and what i did

[lost matrix]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[grim ice]

what do you expect to happen

your command class is basically empty

[drifting bluff]

wait a minute

how do i do it so when i execute the command it says something ib chat?

or like how do i declare the player variable?

[tardy delta]

look at the CommandExecutor signature

[drifting bluff]

where

[lost matrix]

    @Override
    public boolean onCommand(CommandSender sender, Command command, String s, String[] strings) {
        sender.sendMessage("You have used a command");
        return true;
    }

[drifting bluff]

thx

so i can see the plugin in /pl and i dont get errors reloading, but still i cant type the command
https://imgur.com/qbWamrC

[blazing ocean]

don't reload

[drifting bluff]

RESTART?

[lost matrix]

Ofc, never use reload

[drifting bluff]

fgor what is there rleoad then

[lost matrix]

Type in /reload and read the message. Its not supported, will cause problems and is an artifact from the past.
Also make sure to update your plugin every time you compile it. I have the suspicion that you simply forgot to place the new jar in your plugins folder.

[drifting bluff]

oh my gosh im so DUMB

😭

[lost matrix]

Happens

[grim ice]

and it's generally better to learn some java basics

[drifting bluff]

yea

[grim ice]

before trying spigot, although you can do it any way you want

[drifting bluff]

wait 2hex are u a devloper of photon gaming or like what u doing here

lol

[grim ice]

Nah that server doesnt even pay lol

i just spend free time there when im bored

[drifting bluff]

ah lol

but u know itsallay

[grim ice]

I do

[drifting bluff]

from where?

[grim ice]

i help him with his server sometimes

[drifting bluff]

nice

[drifting bluff]

works now :skulli

when i type it it shows thistho

and not the message

it shows: You have used a command

[sand spire]

Which PersistentDataType and value should I use if I use the key as a boolean where if the PDC has the key it's true and if it doesn't it's false?

[lost matrix]

Sounds like what you would expect. I dont see a problem.

[slender elbow]

boolean/byte, that's the smallest value you can store and use as a "marker" for that kind of thing

[lost matrix]

Byte or boolean. Generally doesnt matter.

[sand spire]

Thanks 👍

[lost matrix]

But if its on an entity then you can as well use scoreboard tags

[remote swallow]

internally they are the same thing

[fossil flax]

someone know what the code i have to write on my spigot plugin to get the server server name wheres the player is?

[lost matrix]

Are you talking about a multi-server setup with a proxy?

[grim ice]

player.getServer().getName()

wait a sec

That gives you the server implementation name... nvm

[fossil flax]

yes with bungeecord

[lost matrix]

That would be requested from the proxy via plugin messaging

[fossil flax]

how can i do that?

[lost matrix]

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/#getserver

I personally hate this system and built something on top which returns a CompletableFuture instead

#help-server

[grim ice]

Not possible

only with NMS

[lost matrix]

I mean

Yeah

[hexed bluff]

then how do hcf servers do it

[uncut grove]

Hey,

I tried to make a command that spawns a npc on the current Position. I heared that in the 1.21 you need a ServerEntity to spawn the npc. I uploaded my code here: https://pastebin.com/BMLs1wuT In the marked section I Think I have done somethin wrong or missed something. Can anyone look through it? When I run this code nothing happens.

~ @uncut grove

[granite night]

how do I get the plugins folder path? i mean server/plugins not server/plugins/<myplugin>

[lost matrix]

Go one folder up from your plugins folder?

[wet breach]

path.getParent()

[lost matrix]

Any exceptions? Im not seeing a spoofed connection (which is needed for newer nms npcs)

[uncut grove]

nope, nothing. Do you know a doc / tutorial where I can see how the spoofed connection is working?

[granite night]

ty it works

[lost matrix]

public class PlayerConnectionSpoof extends ServerGamePacketListenerImpl {

  private static final Connection DUMMY_CONNECTION = new Connection(PacketFlow.SERVERBOUND) {
    @Override

  };

  public PlayerConnectionSpoof(ServerPlayer player) {
    super(MinecraftServer.getServer(), DUMMY_CONNECTION, player);
  }
}

this.nmsPlayer.connection = new PlayerConnectionSpoof(this.nmsPlayer);

Does this work for 1.21 I copied it and it says that what you can see in the imghttps://imgur.com/a/1QntRsX

[lost matrix]

You need to override one more method

[sweet pike]

do i import a new NMS class as the moj or spigot mapping?

[young knoll]

moj

[sweet pike]

im not even close to compiling, but i certainly can't do it with that

[tardy delta]

cast it to the right functional interface

or use a lambda

[fallen tree]

what am i doing wrong?

[sweet pike]

is that how it's usually done? that's quite a lot of NMS to edit

[uncut grove]

witch one?

[tardy delta]

ugh nms

[slender elbow]

or use a good decompiler

[sweet pike]

i'm literally stuck idk what to do. if i resolve these errors how i usually would then it would result in a lot of NMS code changes that i don't really think are needed

[remote swallow]

making lynx decompile it and fix errors isnt a good decompiler

[slender elbow]

vineflower is a great decompiler :3

[eternal night]

what about wineflower tho

[remote swallow]

lynxflower when

[sweet pike]

i mean im using decompiled mojang mappings to try to contribute

[river oracle]

What about CabernetMC aka LynxPlayzMC aka Y2KMC aka InventoryPR aka 🍷flower

[fallen tree]

can anyone please help me out?

[eternal night]

that is too much for these simply minds, they'd never understand

[slender elbow]

you can't just use the server jar like that anymore

[fallen tree]

what do i need then

the api?

where do i get the api

[slender elbow]

use maven or gradle

if you don't need nms, that is, and you shouldn't, lol

your byte serialization impl is flawed

you don't need to import any jars like that

maven will provide you with the api

my fav server impl is @sterile axle c one

[river oracle]

I'd honestly trust a server impl in go more than rust tbhhh

[remote swallow]

idk if it was c or ++ or #

[river oracle]

Plus the go server wouldn't be aids to write plugins for

[blazing ocean]

my fav server impl is that kid who made a server impl in arduino cpp

[blazing ocean]

damn

[remote swallow]

y2k make an 8bit server impl

[tardy delta]

imagine trusting a gc over no gc

[river oracle]

That's probably not realistically possible

[remote swallow]

make it possible

[river oracle]

I mean you'd Really have to cut down on things to make it possible

I'd have to do it in C or assembly too

[blazing ocean]

go is more aids than rust

[tardy delta]

lol

why

[blazing ocean]

the error handling 😭

missing generics

[tardy delta]

what error handling?

[blazing ocean]

goofy ahh syntax

[tardy delta]

the optional ok like semantics?

you prefer exceptions?

[blazing ocean]

file, err := Open(path)
if err != nil {
    return "", err
}
contents, err := Read(file)
if err != nil {
    return "", err
}
return contents, nil

[eternal night]

go has generics

thanks

[blazing ocean]

wha

[eternal night]

not really all that powerful, but that is fine

the language is supposed to be dead simple to read

[blazing ocean]

func SumIntsOrFloats[K comparable, V int64 | float64](m map[K]V) V {
    var s V
    for _, v := range m {
        s += v
    }
    return s
}

what the fuck

[eternal night]

Yea

[blazing ocean]

that's just

no

just no

[eternal night]

better than rusts

easy peasy

[blazing ocean]

rusts is simple

[tardy delta]

its great isnt it

[blazing ocean]

no

rusts ? better

[tardy delta]

its all syntax sugar

i dont like languages which hide everything they do

[blazing ocean]

it's unreadable in go

[eternal night]

[tardy delta]

💀

[eternal night]

brille fielmann?

[blazing ocean]

like if you work with large codebases in go it just becomes very unreadable

[eternal night]

the fuck are you talking about

[tardy delta]

it actually doesnt

[blazing ocean]

half the code is error handling and returning

[eternal night]

yea it is verbose, does not make it hard to read / unreadable

I'd argue the fact that you can see exactly what happens with each error is rather nice

[blazing ocean]

it clutters the code a lot tho

[eternal night]

instead of blindly throwing shit up the callstack with ?

[blazing ocean]

i really like go just that's annoying

[remote swallow]

i love blindly throwing shit up

[tardy delta]

i love unwinding the callstack into eternity

[blazing ocean]

just .expect it

[tardy delta]

just found out that if you hold shift and click reply, the ping author thing is off

expect just pannics 💀

[sweet pike]

once i've made my changes to CraftBukkit, how can i obtain a testable spigot jar, before making any PRs or commits to stash, so i can test if my stuff works. event api needs a bit of testing, so how do i go about doing this?

i don't think that's illustrated anywhere on any guide

[eternal night]

i do not know

@river oracle might

[shadow night]

compile it with maven maybe?

[eternal night]

Well, you'd be missing spigot patches applied on top

[river oracle]

You can't I always test with cb

I.make a cb plugin

[shadow night]

Doesn't some maven plugin apply them automatically

[sweet pike]

wdym

[eternal night]

[river oracle]

Make a test plugin for craft bukkit

It's basically just spigot minus components

[sweet pike]

yeah but what server jar do i run that on?

[river oracle]

Use mvn package

And run the bootstrap jar

[sweet pike]

hi guys

[kindred sentinel]

I want to make horses act like real horses, responding to the player with some delay. Like I go straight on a horse and when I try to stop, horse is still going straight some time

Do u have ideas how to make it?

[hollow oxide]

hi,
my commands are lame...

i want to put color on them, is it possible and how?

thx for your time

[paper viper]

Are you using a command library?

[hollow oxide]

nope

[paper viper]

Brigadier handles the argument colors

[remote swallow]

you would need to use brigadier

some command frameworks have support for it

[paper viper]

Brigadier + Commodore

Some other APIs for example Cloud have built in support

You can’t do it with the built in api tho

[eternal night]

(just use a command library)

[hollow oxide]

how to use the brigadier to make it have color?

[eternal night]

by deep diving into an internal library and NMS, learning brigadier which isn't documented, and then doing it 👍

[hollow oxide]

;-; sounds hard

[paper viper]

Use a command library like what lynx said

[hollow oxide]

but brigadier isn't documented

[slender elbow]

then use another command framework

like cloud or commandapi

the world is your oyster

[hollow oxide]

k, i'll try

[onyx fjord]

did anything happen to Particle.REDSTONE in 1.21?

[slender elbow]

api particle names align with the vanilla names now, so, that'd be dust

[uncut grove]

Hey,

I tried to make a command that spawns a npc on the current Position. I heared that in the 1.21 you need a ServerEntity to spawn the npc. I uploaded my code here: https://pastebin.com/BMLs1wuT In the marked section I Think I have done somethin wrong or missed something. Can anyone look through it? When I run this code nothing happens. I also not recive any errors.

~ @uncut grove

[onyx fjord]

dang why did it have to be a breaking change...

[chrome beacon]

There are a couple of those

compile against an older version if you want to keep backwards compat

[ancient forge]

I can use java 22 to make plugins right or do i need to use 17?

[blazing ocean]

what mc version are you targeting

[ancient forge]

1.20.6

[blazing ocean]

use java 21

[ancient forge]

Its saying my main class is never used. Im following a youtube video and i got exactly what he has but mine says that what is my main class is never being used

Main```package org.mopo.cowCannon;

import org.bukkit.plugin.java.JavaPlugin;

public final class CowCannon extends JavaPlugin {

@Override
public void onEnable() {
    // Plugin startup logic
    getServer().getPluginManager().registerEvents(new EntityListener(), this);

}

@Override
public void onDisable() {
    // Plugin shutdown logic
}

}

Listener ```package org.mopo.cowCannon;

import org.bukkit.entity.Cow;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerInteractEntityEvent;

public class EntityListener implements Listener {

    @EventHandler
    public void onEntityRightClick(PlayerInteractEntityEvent event) {
        if (event.getRightClicked() instanceof Cow) {
            Cow cow = (Cow) event.getRightClicked();

            cow.getWorld().createExplosion(cow.getLocation(), 2f);
        }

    }
}

[tardy delta]

it isnt going to be used in your own code

the server is gonna load it

[ancient forge]

nvm i figured out what it was, the run was set to current file and not running the actual thing

[buoyant viper]

the fun part is that when i did this, i broke future compat

plugin i wrote for 1.16.5+ wouldnt work on 1.20.6 bc of renames

[chrome beacon]

?

You should submit that as a bug

[buoyant viper]

it was something with potions idr

i also already updated that code so i dont even have the old one that it broke :c

no VCS used bc its just a personal plugin for my smp

[chrome beacon]

should always use vcs

[rough ibex]

all of my personal stuff uses git lol

Hi, I am using this code to overwrite the /msg, message, w, whisper... etc commands
It works, but after using /msg the next time i type in chat regularly i get kicked with this message

"Received chat packet with missing or invalid signature."

public void onOperatorSet(PlayerCommandPreprocessEvent event) {
        String cmd = event.getMessage();

currently tryna figure out wtf is wrong with my byte serialization code

so many generics 😭

[eternal night]

[river oracle]

you like that emoji huh

its solid I can't blame you

[eternal night]

i do and yea it is great

[slender elbow]

wdym Codec only has two type parameters :kappa:

[river oracle]

yeah but then you also have like the other stuff inside of it 😭

idk what they're all called

[slender elbow]

russian doll?

[young knoll]

Russian nesting codecs

[river oracle]

Dyanimc<T> or whatever

which does who knows what kekw

welp I think I was missing using DFU so I guess I will be looking at this shit all night

[slender elbow]

it holds the DynamicOps and a T so it stays within the domains of that ops

[river oracle]

yep that went over my head Kekw

[slender elbow]

xd

dw I'll have it figured out by the weekend

[eternal night]

MinecraftServer.getServer().CraftServer

Or something

[river oracle]

why is it deprecated

[slender elbow]

you tell me, it's in a cb patch :^)

"static abuse bad" or smth idk

[river oracle]

deprecating internals of your own patch???

interesting

I'm ngl I'm just staring at a Codec and datafixer rn and just being like yep hmhm and nodding.

[eternal night]

common first reaction

[river oracle]

I don't think I'm capable of doing this right now 😭 I'm just sifting through Dynamic and am like what the fuck is this, then I find myself like 20 classes in and confused as all hell

[slender elbow]

checks out

[eternal night]

I mean, whatever you are doing, you won't need a full understanding on the composite nature that is codecs and data converter

Be smart, find places where this is already used for similar purposes in internals, copy paste, profit

[slender elbow]

copying proprietary code ???

never

[river oracle]

so real tbh

actually 🤓

its open source

[slender elbow]

vanilla?

interesting

[river oracle]

oh yeah it is. My decompiler cracks it right open

no issues there

[young knoll]

Is DFU open source?

[slender elbow]

legally you can't copy minecraft code for cb patches because of the CLA :^)

[remote swallow]

https://github.com/Mojang/DataFixerUpper/

[young knoll]

Yeah

[river oracle]

that's kinda funny cuz its almost nearly impossible to avoid some influence

[young knoll]

It’s one of the things they OSed

[river oracle]

god damnit its not javadocs

😭

[eternal night]

again, you don't need an understanding of dfu

find where mojang uses it (for exactly the same purpose as you are)

[young knoll]

I wish they’d OS the NBT system

[eternal night]

because, surprisingly, items loaded in newer versions of minecraft are ran through DFU

[remote swallow]

aikar has contributed to dfu?!

[young knoll]

How else would it get so over-engineered

[slender elbow]

Nah if that was the case spigot would be more over-engineered

[grim ice]

it will not

[grim hound]

I just had to get the local network anyway

[grim ice]

it'll give you a private ip

for your public ip, this will work

uhhh the spigot plugin im creating is meant for 1.12.2

can anyone point me in the right direction to resolve this?

[lethal knoll]

Hey all, does anyone have an idea how to solve this? Or is this a bug?
java.lang.IllegalArgumentException: missing required data class org.bukkit.Color

This is because of the 1.21 update

[worthy yarrow]

More context

[worldly ingot]

The test should tell you which method is missing annotations

If it's not here, it will be above. The methods and parameters are listed somewhere in the build log

But basically a method (likely you have) added is missing a nullability annotation either for one of its parameters or on its return type

[worldly ingot]

This is related to a particle probably? But Kat's right. Need more context :p

[oblique peak]

hi, this is a really silly question coming from paper, but i can't seem to use Bukkit.getPluginsFolder() it just gives a 'cannot resolve method error'

[worthy yarrow]

.getServer

[worldly ingot]

Bukkit doesn't have this method

[worthy yarrow]

darn

[oblique peak]

yes i figured

wait

[worthy yarrow]

Thought we might be cool like that

[oblique peak]

doesnt have getserver?

or doesnt have

[worthy yarrow]

your method

[worldly ingot]

Doesn't have getPluginsFolder()

[oblique peak]

ah

[worldly ingot]

Alternative would be yourPluginInstance.getDataFolder().getParent() and that should be the plugins folder

(getDataFolder() is protected though, worth noting :p)

[obtuse hedge]

so uh

what was that api

for text components

where you could make templates

and use them over and over

[sweet pike]

what's the different between handle[...]Event and call[...]Event inside CraftEventFactory. i've tried taking a look at some of the methods but i can't wrap my head around why certain events are named as call vs handle

[echo basalt]

I believe getFile is but getDataFolder isn't

Unless you mean a different kind of protected

[worldly ingot]

Oh, yeah, it is public

It's part of the Plugin interface

[grave lion]

am i missing something? it wont load keys that don't have values. https://pastebin.com/UpRj7TJw

[obtuse hedge]

?

[valid burrow]

give an example

what does teams contain

seems like a very chaotic strucutre

try properly organizing that first

then making a proper mysql setup shouldnt be that comlicated anymore

remember to normalize your db and follow all the Schema rules

[worthy yarrow]

public TitlesGUI(PlayerTitlesPlugin plugin) {
        this.plugin = plugin;
        this.titles = new ArrayList<>(plugin.getTitleManager().getTitlesMap().values());
        this.pages = new HashMap<>();
        initPages();
    }```

So as setting titles to a new array list in the constructor, will this always reflect the current values of the map in titleManager?

public void updateTitlesList() {
        this.titles = new ArrayList<>(plugin.getTitleManager().getTitlesMap().values());
        pages.clear();
        initPages();
    }```
rather is it necessary to redefine the titles list every time in order to reflect changes of the values in titlesMap?

[wide cipher]

idk what the error is here, says Cannot resolve method 'stream(List<World>)'

[echo basalt]

getWorlds returns a list, not an array

Arrays.stream is a method that converts a T[] into a Stream<T>

What you want is List#stream

[worthy yarrow]

illusion I have another project for you to yell at

[echo basalt]

no

I have work to do

can't waste my time

[blazing ocean]

what

[obtuse hedge]

someone told me

to make text component templates

that I could reuse whenever I needed to use it

[blazing ocean]

wha

minimessage..?

[obtuse hedge]

maybe

idk

[spring trail]

I downloaded the Timber mod but it doesn't appear in the mods section on the Aternos server. How can I add it?

[nova notch]

sir this is a #help-development

whats spigot got to do with a mod or aternos

https://hastebin.com/share/hegilelixi.css

I've been getting this same stupid error again and again. Can someone help?

I need an expert :)

[dusty herald]

It looks like you’re encountering an IllegalArgumentException with the message “Plugin already initialized!” during the startup of your Minecraft plugin. This exception typically occurs when a plugin is being initialized more than once. Here are a few steps you can take to resolve this issue:

Ensure Singleton Pattern: Make sure that your plugin’s main class is following the singleton pattern. It should only be instantiated once throughout the lifecycle of the plugin.
Check Constructors: Look for multiple instantiations of your main plugin class or other classes that should only be instantiated once. The stack trace points to CommandsPartOne and Main classes. Ensure that you’re not creating new instances of these classes in your code unnecessarily.
Review Plugin Enabling Process: The error occurs during the onEnable method. Review this method to ensure that you’re not performing any actions that would lead to re-initialization of the plugin.
Update Dependencies: If you’re using external libraries or dependencies, make sure they are up to date and compatible with the version of the server you’re running.
Check for Conflicting Plugins: Sometimes, other plugins can cause conflicts. If you recently added a new plugin before this error started occurring, try removing it to see if the problem persists.
Server Version Compatibility: Ensure that your plugin is compatible with the server version you’re using. The stack trace mentions paper-api-1.21-R0.1-SNAPSHOT.jar, so your plugin should be compatible with this API version.

[near furnace]

I can provide you the code, its a custom made plugin

[dusty herald]

do you have more than one plugin

that has the same plugin.yml name

[near furnace]

no, only one

[dusty herald]

send code

[near furnace]

which one do you want

[dusty herald]

yes.

[near furnace]

i have:

a commands package

[dusty herald]

send main

onenable

part

[near furnace]

which includes classes:

1. CommandsPartOne
2. FeedCommand

[near furnace]

ok

package com.lexplugins.plugin;

import com.lexplugins.plugin.commands.CommandsPartOne;
import com.lexplugins.plugin.commands.FeedCommand;
import com.lexplugins.plugin.commands.InvincibleCommand;
import com.lexplugins.plugin.listeners.JoinLeaveListener;
import com.lexplugins.plugin.listeners.LeaveBedEvent;
import com.lexplugins.plugin.listeners.SheepShearListener;
import com.lexplugins.plugin.listeners.XPBottleBreakListener;
import org.bukkit.Bukkit;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerBedLeaveEvent;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.plugin.java.JavaPlugin;

public final class Main extends JavaPlugin implements Listener {

    @Override
    public void onEnable() {
        // Plugin startup logic
        Bukkit.getServer().getConsoleSender().sendMessage("Plugin booting up...");
        Bukkit.getPluginManager().registerEvents(this,this);
        Bukkit.getPluginManager().registerEvents(new XPBottleBreakListener(), this);
        Bukkit.getPluginManager().registerEvents(new SheepShearListener(), this);
        Bukkit.getPluginManager().registerEvents(new JoinLeaveListener(), this);
        Bukkit.getPluginManager().registerEvents(new LeaveBedEvent(), this);
        getCommand("invincible").setExecutor(new InvincibleCommand());
        getCommand("suicide").setExecutor(new CommandsPartOne());
        getCommand("feed").setExecutor(new FeedCommand());

    }

    @Override
    public void onDisable() {
        // Plugin shutdown logic
        Bukkit.getServer().getConsoleSender().sendMessage("Pluggin shutting down...");
    }
}

also on an irrelevant note, only the main class can contain the onEnable() and everything else can't have it or else it will break right?

[dusty herald]

yes

if any other class has JavaPlugin it will break the plugin

[near furnace]

so this is the main class

[dusty herald]

yup

[near furnace]

yes. thanks

[near furnace]

did you decipher the problem?

[dusty herald]

send CommandsPartOne code

[near furnace]

roger

package com.lexplugins.plugin.commands;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.*;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public class CommandsPartOne extends JavaPlugin implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {

        if (sender instanceof Player p) {

            p.setHealth(0);
            p.sendMessage(ChatColor.RED + "Man, you used /suicide... What did you think was going to happen?");

        } else if (sender instanceof ConsoleCommandSender) {

            Bukkit.getServer().getConsoleSender().sendMessage("The console ran the command.");

        } else if (sender instanceof BlockCommandSender) {

            Bukkit.getServer().getConsoleSender().sendMessage("The command block ran the command.");

        }

        return true;
    }
}```

[dusty herald]

** extends JavaPlugin **

[worthy yarrow]

^

[dusty herald]

see the problem?

[worthy yarrow]

Also there's no reason to be logging

You're only performing operations if the sender is a player

[near furnace]

ohhh

OHHHHHHHHHHHHH

[worthy yarrow]

So you can remove all the useless else / else ifs

[near furnace]

hehe im following a tutorial

so it like

showed us how to log entities other than players

thats why :)

[worthy yarrow]

Also Bukkit.getLogger() exists

[near furnace]

and i always run into errors because i try to do some stuff a little bit different from the tutorial

[near furnace]

wdym

whats that and how do u use that

[worthy yarrow]

instead of getServer.getConsoleSender

[near furnace]

oh

i originally used System.out.println

[worthy yarrow]

Bad

Just use Bukkit.getLogger

[near furnace]

then someone told me to use bukkit.getServer().getConsoleSender

[blazing ocean]

kek

[dusty herald]

ALEXA WONT STOP FARTING

[near furnace]

@worthy yarrow

Bukkit.getServer().getLogger().sendMessage("The command block ran the command.");```

.sendMessage is not valid there, if i use .getLogger

[worthy yarrow]

thats just extra work + bukkit.getLogger lets you choose a level ie: #severe("error message here")

press . after getlogger

[shadow night]

aren't you supposed to use your own logger and not the bukkit logger?

[worthy yarrow]

and see your choices

[worthy yarrow]

Supposed to but for the sake of not doing consoleSender kek

[near furnace]

Bukkit.getServer().getLogger().warning("The command block ran the command.");```
do i use this?

.warning is the closest to .sendMessage

[worthy yarrow]

sigh

[near furnace]

oh severe

[worthy yarrow]

it's just a logging level

[shadow night]

aren't loggers a basic concept in java

[worthy yarrow]

Idk at this point

[shadow night]

or, well, I guess it is a bit above basic but not advanced

what do you call it

[worthy yarrow]

intermediate?

[near furnace]

well im not intermediate at all

[worthy yarrow]

I'd call logging a basic concept unless you want to make it complex

[near furnace]

Bukkit.getServer().getLogger().severe("The command block ran the command.");```
so this just gets the server. gets the thing/logger which is trying to send the command, then what type to send

[shadow night]

well, begginers usually use System.out

loggers are something more advanced

[worthy yarrow]

I use sout for debugs most of the time, but thats debugging I suppose

[blazing ocean]

you can just use Bukkit.getLogger btw

but you should be using your plugins logger

[near furnace]

omg

im understanding nothing

what is these loggers

[shadow night]

getLogger().debug()?

[near furnace]

i just want to print a message to the console 😭

[shadow night]

an abstraction

a very useful one

[worthy yarrow]

.severe / .warning / etc, is just a level of logging, you know when it outputs in console "info: xyz | warning: xyz | etc

its not that hard

[near furnace]

whats wrong with using
Bukkit.getServer().getConsoleSender.sendMessage("hi hello this is a message")

[shadow night]

everything...

[quaint mantle]

how to enable spawn entities ?
i mean 1.19.4 feature holograms,items

[near furnace]

how to use the plugins logger?

[near furnace]

wdymm :((

[worthy yarrow]

plugin.getLogger

Your main class is the plugin reference

[shadow night]

and lets see whether we'll have to call ?di

[worthy yarrow]

kek

[near furnace]

<main_class>.getLogger()?

[worthy yarrow]

uh

[shadow night]

sigh

[worthy yarrow]

It'd do you a lot of good to actually learn java before using an api

It's also not that we can't help you it's rather just that spoonfeeding you is not going to help teach anything

[near furnace]

i only learnt java absolute basics, like i can make a very very simple number guessing game thats it

[worthy yarrow]

So then go learn it better

[near furnace]

but i didnt know you have to learn java to the point you can build spaceships to learn minecraft plugin development

[worthy yarrow]

Well when you put in those terms, you're not even at a level where you can build a fire with java

So just take the time to learn the language before you attack an api

[near furnace]

how good do you think someone should be before learning api's like spigot/bukkit

[shadow night]

knowing what dependency injection is and how to operate a logger

[hazy parrot]

At least know basic principles

[worthy yarrow]

When you say basic, you probably mean you know 6 total operators and thats about it

This isn't really even what you can call a level

You need a foundation of the syntax at least before trying to use an api

[shadow night]

once you can write me a mapping file that changes net/minecraft/util/math/MathHelper to net/minecraft/util/math/Meth come back (that's a joke btw)
