[onyx fjord]

didnt know that was possible in java

i feel too much power

[drowsy helm]

Indeed, but youll get a method clash

[azure zealot]

Just look into the bungeecord PipelineUtils

There you can see the order

[slender elbow]

huh?

[drowsy helm]

If the names for methods clash compiler forces you to explicitly call them by class

[onyx fjord]

no issues so far

[slender elbow]

no?

[onyx fjord]

are you sure

if they collide intellij warns me

[slender elbow]

if any default methods' signature clash the implementing class has to explicitly implement it but nothing about calling

[drowsy helm]

Ye default methods

[slender elbow]

but like, if there are no default methods in the itfcs you also have to implement them

if you mean invoking the default methods via super on interfaces you always have to specify the interface name

regardless of clashes

[grim hound]

how does Metadata work on Worlds?

[eternal oxide]

MetaData is non persistent

[grim hound]

okay, but what does it change?

[eternal oxide]

change?

[grim hound]

so does it not affect what the server sends?

[eternal oxide]

You are talking about Bukkit Metadatable?

[grim hound]

is it some internal system plugins use

[slender elbow]

it was meant to be an api for plugins to communicate and interact with each other

but it was never finished

and it's ass and it's leaky

[eternal oxide]

and itws leaky.; almost no one uses it now

[grim hound]

oh I thought it was something useful

aight then

[slender elbow]

it's basically just a Map for plugins

but bad

[hybrid turret]

sooo i did some more research and i found... nothing. i still have no idea how i would set a skin for a protocollib-npc ._.
If anyone can tell me how, please ping me :)

[grim hound]

do not

use

protocollib

also, skins are set with PlayerInfoUpdate I think

[hybrid turret]

bruh 50% say do 50% say don't and i want to be able to interact with an npc

and apparently without protocollib, it's ass to code

bc you have to do funky netty pipeline shit

i don't know a lot about packets yet and i'm trying to learn xd

[grim hound]

tell me, how told you to use protocollib?

[hybrid turret]

7

more or less

[grim hound]

use PacketEvents

[grim hound]

7 people?

[hybrid turret]

potato potato

[hybrid turret]

7smile7

[shadow night]

I agree

[grim hound]

old man

he is out of times it seems

[hybrid turret]

don't these 2 do the same thing?

[grim hound]

packet events does it like 20x better

it's not even a competition at this point

[shadow night]

I believe you can also shade packetevents right?

[grim hound]

literally beat pl in every possible way

[grim hound]

yes

[hybrid turret]

https://www.spigotmc.org/threads/spawning-client-side-entities-with-protocollib.552259/

[shadow night]

Way better lol

[grim hound]

altough, retrooper doesn't really like that

[hybrid turret]

(what does shading do btw?)

hmmm

[grim hound]

send the date

[hybrid turret]

i mean

[shadow night]

🗿

[hybrid turret]

apr 3 2022

[grim hound]

send when this was written

[hybrid turret]

so not THAT old

[grim hound]

internals completly changed

for packet events

[shadow night]

It's ancient

[grim hound]

it's incomparable to pre 2.0.0

[hybrid turret]

o-kay

uhm

right, then i'll try PacketEvents

[grim hound]

that's why it's much faster

[hybrid turret]

uhmmm is there no tutorial on how to include it in the code?

on the resource

like "installing" i mean

[shadow night]

Hasn't retrooper been working on a wiki for pe?

[hybrid turret]

i think i found it :)

through the github and then it's on its own wiki

and i suppose i can replace NMS with PE as well?

or are there still certain things i would need nms for?

[shadow night]

well, if they aren't packet related, then yeah

[hybrid turret]

so e.g. changing the name in a gameprofile i suppose

[umbral ridge]

[hybrid turret]

catto

hi spex

[umbral ridge]

HI

im a cat

[grim hound]

how much

[umbral ridge]

1 pound of cat food per day

[hybrid turret]

fat cat

[onyx fjord]

except protocollib has no wrappers

at least no usable ones

wrapper repo had last commit like 2 years ago

[hybrid turret]

damn

[atomic niche]

Not specific enough.
What flavour? What brand?

[hybrid turret]

probably only the best

[buoyant viper]

one million beers?

[hybrid turret]

PacketEvents is actually pretty cool. At least from the kody simpson tutorial i've watched

[urban escarp]

is there method to get players xp in for loop and calculate it?

[slate siren]

Aaa

[alpine urchin]

https://packetevents.gitbook.io/docs might be a useful guide for now

although still WIP, but should be a good introduction

[hybrid turret]

yeah i got that open rn

oh hi retrooper

the man himself

[alpine urchin]

very odd coincidence i saw the message

[hybrid turret]

i don't quite understand how i would create a WrapperPlayServerSpawnPlayer packet

i feel stupid xd

[alpine urchin]

Have you read the sending packets page on the guide?

[hybrid turret]

yeah i've been trying nms first, then plib and now i'm on ur api

[hybrid turret]

the sending itself is not the problem

it's about this specific packet

[alpine urchin]

what minecraft version are you on

[hybrid turret]

e.g. the EntityDataType

[hybrid turret]

1.19.4

[alpine urchin]

the metadata is optional

[hybrid turret]

my ultimate goal is to spawn an NPC with a skin fetched from mojang

[alpine urchin]

you can look at how our NPC class works

that provides such functionality

[hybrid turret]

(that in the end can be interacted with)

[hybrid turret]

oh i didnt know there was one

[alpine urchin]

you can use it, but the moment someone makes a complete packetevents extension that fulfills the NPC feature, we might remove it

we have so many components in the API, we're not sure if it's ideal to also allocate time maintaining a tiny NPC library

while an extension could primarily focus on that

for spawnplayer you could add no metadata list

[hybrid turret]

oh

[alpine urchin]

but do you understand how metadata works in the protocol generally?

[hybrid turret]

since i started like 30 minutes ago, not quite, no 😅

[alpine urchin]

https://wiki.vg/Entity_metadata#Entity_Metadata_Format

we have a community that can provide support, but wiki.vg has documentation for parts of the protocol

it would be a strenuous task if we also documented all concepts in the protocol

as its always changing

[hybrid turret]

i see

[alpine urchin]

EntityDataTypes class provides instances of EntityDataType

[hybrid turret]

ohhh

[hybrid turret]

does this mean there will just be another maven import at some point and everything else will stay more or less the same?

[alpine urchin]

i suggest leaving an empty metadata list in SpawnPlayer packet, and sending a EntityMetadata packet later

[alpine urchin]

possibly, we already have packetevents extensions that abstract Metadata

[hybrid turret]

i see

are there docs for the npc class?

Oh right, i also kinda can‘t find the doc to how to shade eventpackets :(

[alpine urchin]

Not advised but https://github.com/retrooper/packetevents/wiki/Shading-PacketEvents

expects you to know how to shade a dependency generally

[hybrid turret]

Why not advised?

[alpine urchin]

Someone summarized it in this suggestion for a project: https://github.com/GrimAnticheat/Grim/issues/1528

[hybrid turret]

so if i understand correctly an example would be this:

            <relocation>
              <pattern>com.github.retrooper.packetevents-spigot</pattern>
              <shadedPattern>shaded.packet.path.packetevents</shadedPattern>
              <minimize>true</minimize>
            </relocation>

[hybrid turret]

oh

[alpine urchin]

I primarily use Gradle so i don't remember off by heart how it looks like in maven

probably correct

looks good to me at least

[hybrid turret]

so shading results in performance issues?

[alpine urchin]

No, performance loss and performance issues are two different things.

[hybrid turret]

oh

i mean loss ig?

[alpine urchin]

Just, if two plugins shade the library, packets are encoded & decoded twice.

Now, think of this, tons and tons of plugins shade the library.

Some users really have servers running 5 or more instances.

This is just an unnecessary performance drawback and you would be contributing to the problem.

This is why we raise awareness.

[hybrid turret]

i see

okay then i'll not shade it

and if i understand this correctly users then will just have to add the api to their plugin folder?

[alpine urchin]

As people see, the pros outweigh the cons, it's not just because it makes me feel some type of way or whatever

it benefits your users, although they might not see it

[alpine urchin]

Correct

[hybrid turret]

alright thanks for the explanation

:))

[alpine urchin]

As you see, it wasn't successful in that issue haha

[hybrid turret]

^

[alpine urchin]

Not really since then people start asking for more functionality and more stuff, when this is not meant to be an NPC library. But it's simple, create an instance of it using our classes, (you'll need to generate a random UUID, you can generate a new entity id using SpigotReflectionUtil.generateEntityId())

then call NPC#spawn on a player channel, you can use getAPI().getPlayerManager().getChannel(player) to get a player's channel

and the npc is visible to them

[hybrid turret]

ohhh

tysm!!

[alpine urchin]

@hybrid turret did you read the entire docs

[hybrid turret]

uhm, maybe, not all of them?

oops

[alpine urchin]

i was just asking

[hybrid turret]

u mean these i suppose?

[alpine urchin]

for a rating

yes

[hybrid turret]

i will

should i tag you when i read them and tell u what i think? bc i got to go for now

[alpine urchin]

sure

yea

[hybrid turret]

alright will do

[stuck oar]

how would i go about making my own chat formatting plugin?

i want it so that it sends a different version of the message to each player

[visual tide]

First thing to think about is what versions to support

[urban escarp]

    public static Integer FactionPlayersPower (FPlayer p){
        int playerPower = ExperienceAPI.getPowerLevel((Player) p);
        int i = 0;
        for (fplayer : i = 0 ; i++) {
        }
        return i;
    }

I'm not very in to for loops, but i really need one, can anyone pls explane? 😅

[visual tide]

Since there’s a huge amount of changes concerning Chat and chat formatting in a ton of versions

[visual tide]

What exactly are you trying to do

[urban escarp]

I want to get an mcMMo power int from all faction players list

[visual tide]

Well then you’re gonna need a list of players

[grim hound]

hehe, good thing you have me

master microoptimizer

[urban escarp]

weird thing is that it returns Set not list

[visual tide]

And then you can use a for loop like
for (Player player : playerList) { /* your code here */}

[shadow night]

Imagine if packetevents, instead of making multiple instances of itself for all plugins, made one

[visual tide]

A set is also iterable

[urban escarp]

FPlayers factionsPlayers = p.getFaction().getFPlayers();

[visual tide]

And can be used the same way as a list in a for loop

[grim hound]

how do you prevent shading tho?

[urban escarp]

ow but how do I + each players power from faction to one integer?

[shadow night]

You don't; you just support it in a way that makes one "main" instance even for shaded plugins

[visual tide]

You can make one sum variable outside the loop and add each players power onto it and then return it

[grim hound]

then what about version differences?

[shadow night]

I did that once using the bukkit service API, but you'd want to add some handling for breaking versions

[grim hound]

also, what about encoder and decoder names?

[shadow night]

You could change the package name every breaking version or something, sounds like a band-aid solution, but as long as it works

[grim hound]

I guess just use the default, fair

[shadow night]

Yee lol

[grim hound]

yo, are you also banned at papermc?

[urban escarp]

thank u very much will try to do something

[shadow night]

Yes

[grim hound]

hehe, so am I

[shadow night]

I had "mayo/naise" in my pronouns, that's why

[grim hound]

they are paper boys

[grim hound]

really? xD

[shadow night]

Their brains consist of paper

[shadow night]

Yeah lol

[grim hound]

when did they ban you?

[shadow night]

I thought people have been joking, but they haven't

[shadow night]

After I left the server

[grim hound]

so what time?

[shadow night]

Idk

[grim hound]

like date

[shadow night]

I don't rememeber

I believe all my messages are gone too

[fluid river]

fa/va are my pronouns now

[shadow night]

Holy shit you still exist?

[grim hound]

how can I search for some text in a github project?

[shadow night]

Using the search button

[slender elbow]

impressive

[grim hound]

yeah I can see that

it's just that it didn't give me any results

of a thing that's clearly in a plugin

[slender elbow]

funny

[shadow night]

Skill issue?

[slender elbow]

are you logged in?

[grim hound]

I mean, it might be a new thing and he just hasn't updated the github yet

cuz else I dunno

[slender elbow]

are you logged in?

[grim hound]

yes

[rugged fern]

is there any way to detect if a player is holding rightclick on an item?

[paper viper]

holding? or just pressing once

[rugged fern]

holding like i want the player to hold an item to get back to the lobby to the player cant accidently click it or smth

[sterile breach]

if i have a task that executes on each tick, will this task be called before or after the events?

[stuck oar]

1.8

i reckon i could figure it out for 1.8 i just dont know the starting point

[river oracle]

No guarantees either way

It depends what events you're speaking of

But it'll be unlikely their is any guaranteed order nor should you bank on any guarneteed order

[sterile breach]

a basic event like block break

[sterile breach]

there has to be a certain order, no?

[slender elbow]

tasks are ticked before worlds tick

at the beginning of server tick

[eternal night]

is that before or after AsyncPlayerChatEvent

[slender elbow]

neither

[shadow night]

Why not at the end

[paper viper]

Hmm, not sure why but sometimes when I end my minigame while the player is on the respawn screen still they get a "Chat disabled in client options." What could this usually entail?

[slender elbow]

hate the game, not the player

i'm just a messenger

[shadow night]

so you do not know any reasons why that is so?

[slender elbow]

nor do i care

[shadow night]

Who do I need to ping to find out

[slender elbow]

md5

[pseudo hazel]

💀

even then, wtf are you gonna do with the reasoning behind the way it works

[shadow night]

Sir @sullen marlin
May I know why this (check the message I replied to) is so

[slender elbow]

it's true https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/commits/6b843d995ffa4b1d5e50124bb67ea58289598596

because it fixes the bug linked

that's why

[pseudo hazel]

2016, thats like since 1.9

[shadow night]

Can I, in theory, make git believe I commited something before the project even existed?

[halcyon hemlock]

am I goog programmer guys

is this real chat

[slender elbow]

sure, rebasing exists

[pseudo hazel]

you are a goog

also that code is terribly beautiful

or I guess more like beautifully terrible

[halcyon hemlock]

It's my actual code from like 2-3 years ago

I guess you really do learn from experience

[pseudo hazel]

yeah

being able to look back on your code and seeing its cringe means you learnt something

[halcyon hemlock]

Not saying I don't write code like that anymore

[halcyon hemlock]

yeah. its unsatisfyingly satisfying'

[shadow night]

I hope you atleast learnt to use pdc in this time lol

[pseudo hazel]

its like wrong in multiple ways, thats usually the best part about bad code

[hybrid spoke]

we all do have code like this

[halcyon hemlock]

I didn't even know what AtomicIntegers were so I used arrays lmaoo

[pseudo hazel]

its never only bad in 1 way

[hybrid spoke]

you just grew out of it

[halcyon hemlock]

readability -10

[hybrid spoke]

but its cool tho, i can even follow the thought process from my old projects, so i can see with the experience i had back then why i did this and that

[quaint mantle]

IDE suggesting arrays instead of atomics: 🗿

[blazing ocean]

why did you use arrays there 🗿

[halcyon hemlock]

cuz I didn't know what atomics were

[hybrid spoke]

scope

[halcyon hemlock]

I was scared to use them

too high level words you know

[blazing ocean]

move || {} my beloved

[halcyon hemlock]

I love how garbage that code is bro

[hybrid spoke]

your garbage is others perfection

i love learning processes

[halcyon hemlock]

Yeah, you can't learn without making mistakes ykwim

[halcyon hemlock]

and vice versa fr

[hybrid spoke]

gotta risk something to achieve something

that being said, brb all in on green

[halcyon hemlock]

all on red

[hybrid spoke]

ew

red only after tripple black, trust

[halcyon hemlock]

😂

[paper viper]

maybe for primitives but

for anything else breh

why cant they create like AtomicObject<T>

[quaint mantle]

Atomic<T>

[paper viper]

AtomicBoolean, AtomicLong, AtomicObject to fit the naming scheme

but actually OptionalInt, then Optional.. idk maybe Atomic<T> is good lol

[hybrid turret]

i suppose i cant set something like "1h 20min" as a score on a scoreboard? only integers?

[pseudo hazel]

correct

if you are talking about the red text yeah

but you can just hide it and show your own text

or atleast I think you can hide it

[slender elbow]

not with the api

:Clueless:

[pseudo hazel]

oh oof

thats a paper thing then I guess 🤐

[eternal night]

[shadow night]

The paperman is here

[pseudo hazel]

anyways I think for my plugin all the scores are just 0

so it doesnt really matter anyways

[shadow night]

Wouldn't that mess up the order or something

[pseudo hazel]

order is also based on team name I think

like it needs some way to order the scores

my code sets all scores to 0

but the line indexes are just the team names

like LINE_1

[tardy delta]

because only 64 bits support for atomic values

doesnt have hardware instructions otherwise

i mean theres AtomicReference<T> but that exists because a reference is pointer sized

[slender elbow]

i mean, the jdk doesn't care about available hardware instructions or pointer sizes

to the point where writing to a long or a double is allowed to not be atomic, but two 32-bit writes

[shadow night]

Is a 32 bit write just an integer

[slender elbow]

ints are 32 bits, yes

[eternal night]

next you'll tell me booleans are 8bits

[shadow night]

Why are things still called 32 bit and 64 bit instead of 4 bytes and 8 bytes

[eternal night]

its cooler

[slender elbow]

surely they aren't widened to 32 bits}}

:Clueless:

[eternal night]

they'd never

[shadow night]

Boost when

[halcyon hemlock]

booleans are 192 bits

🤓 👆

[eternal night]

makes sense

[slender elbow]

never

[shadow night]

I prefer them 512

[shadow night]

Why

[halcyon hemlock]

I prefer them spread in a vec

if computers have memory, we should use it frfr

32 gigabytes vs a single byte. you can fit billions!

[paper viper]

Boolean enjoyers vs int enjoyers

if (0) 🙂

[shadow night]

I use chars

[paper viper]

why cant they allow u to to use ints in conditionals like c++

[shadow night]

or f64's

[paper viper]

like 0 is false everything else true

[shadow night]

Because why

[paper viper]

because it makes sense

[shadow night]

if(0) { return false } else { return true }

[shadow night]

We have booleans for that

[paper viper]

yes and c++ has booleans too lmao but many people use the int conditional

its much easier for doing stuff like array accesses, etc

if you have a huge integer array and want to check if the value is set or not, all you do is that

[shadow night]

Because C++ is an extension of C and C is an ancient language that prefers integers

[paper viper]

breh have u used c++ before?

[shadow night]

a few times

would've prefered to not

[dark moth]

frfr

i aint a game hacker bro

[quaint mantle]

#define false 0
#define true 1

[paper viper]

lmao

[dark moth]

and i couldnt get the syntax

its hard!!111!!

[shadow night]

#define bool int or something

[paper viper]

what

the syntax follows most C syntax languages like java

[dark moth]

i was just not tryna make it obvious that im lazy.

i dont even know java fully

[paper viper]

oh

[shadow night]

Nobody does lol

[dark moth]

thats why i fart everytime i code java

[shadow night]

Java is huge

[dark moth]

i dont even know what the hell does assert do

and abstract

or protected

[shadow night]

asserts something?

[paper viper]

assert is a keyword only used for testing purposes

it only works if u run it with a cmd line parameter iirc

[shadow night]

assert can be used to tell ur IDE to chill

[paper viper]

otherwise its completely ignored

[paper viper]

usually your ide is telling you something important

for ex a null check

[shadow night]

'metadata can be null' not it can't

[paper viper]

whats metadata

[shadow night]

That's how I call my item meta variables

[dark moth]

i just saw assert when something was turning null and intellij was like "are u a fricking dum dum bro this is actually null u dumahh boy"

[paper viper]

well it can be null

[shadow night]

No it can't

[dark moth]

something was turnin null

and intellij said use assert

[paper viper]

itemmeta can def be null

[dark moth]

ye

[paper viper]

theres a reason the hasItemMeta method exists

the method is annotated with @Nullable

thats on purpose for IDE's to warn users

[shadow night]

That's not what it exists for

[dark moth]

@rough drift dude i hate forge teach me ur wayz in fabric plz

[paper viper]

then what is it for

[dark moth]

i couldnt get anywhere with forge

[shadow night]

getItemMeta either returns the current meta or creates a new one for this item (can be null with air)

[dark moth]

lets hope that i can do it on fabric

[shadow night]

hasItemMeta returns whether it has been created yet

[paper viper]

and the itemmeta factory (for some reason) could return null too

i guess for air stacks?

idk

[pseudo hazel]

whats the item meta factory

[shadow night]

It will not tell you whether getItemMeta will return null or not

[dark moth]

@paper viper@shadow night just wanna ask fabric vs forge in modding

[paper viper]

Bukkit ItemFactory#createItemMeta

[paper viper]

so it can be null

[shadow night]

fabric is a bit harder because no API, forge is a bit harder because barely any documentation
So, just use neoforge

[pseudo hazel]

oh right

[shadow night]

Only with air

Which is not my scenario

[pseudo hazel]

would be the same as creating an itemstack and getting the meta from it

[shadow night]

• hasItemMeta will not tell you that

[pseudo hazel]

iirc

[paper viper]

but thats why the ide is warning you

theres reason for it

and it doesnt hurt to just add a single null check

[shadow night]

Technically, it does

[pseudo hazel]

the ide is warning you because the signature of getItemmeta is probably wrongly defined as nullable

[shadow night]

A single useless if doesn't hurt performance a lot, but imagine 200 if's

[paper viper]

it can be null if it's an air stack

thats why its @Nullable

[pseudo hazel]

okay so then why would the check be useless

[paper viper]

wdym

[shadow night]

Which will occur in 0.001% of all scenarios

[dark moth]

ty bro

[paper viper]

literally no difference in performance

[pseudo hazel]

if you know its not gonna be air, you don't have to check it

[shadow night]

There is?

[dark moth]

bro these guys are fighting over of a method

[paper viper]

why tf would u have 200 null checks lol

[shadow night]

An if check is an operation, an operation consumes some time

[dark moth]

is it even neccesary ?

[eternal oxide]

Fabric community is nicer than Forge

[shadow night]

Because you (or other plugins) access an item meta 200 times on total?

[paper viper]

and theres literally no performance issue

[shadow night]

No issue, but there is an impact

[paper viper]

theres literally not omg 💀

[dark moth]

forge vs fabric in modding bro this mf called raydan answered neoforge like wth didnt even know thas a thing

[paper viper]

micro optimizations

like bruh

"micro optimizations add up"

[shadow night]

neo is better

[paper viper]

then in that case use final for everything cause its "marginally" faster lol

[shadow night]

They eventually do. Also, useless if checks bloat your code

[worthy yarrow]

Are stream methods slower than iterator methods? ie: stream.findFirst as opposed to iterator.next

[shadow night]

There is a difference between removing something and adding something for micro-optimizations

In this scenario, it increases readability, LOC and works as a micro-optimization

[visual tide]

Choosing neo over forge is more of a morality/ethics thing imo

Not supporting lex :p

[shadow night]

Nah, neo has some good features and I believe they are also decently documented (in difference to old forge, documenting nothing)

[paper viper]

i'm not arguing about this. computers are capable of billions of operations and a null check is literally a O(1) operation

probably even no overhead at all

[shadow night]

And yet it's bloat!

Just remove it

[paper viper]

its not bloat if you are covering an edge case...

nvm im done

[shadow night]

You'll never get an AIR stack in 98% of scenarios

[paper viper]

yea then the 2% chance u do... 💀

[shadow night]

Those are scenarios where you can add that null check

Most of the time checking whether the stack is null is enough

[worthy yarrow]

Just gonna assume you guys don't know :p

[visual tide]

One might suggest that forks could implement logic that yields AIR stacks where spigot would yield null 🤓☝️

[shadow night]

I believe streams are slower in some scenarios but Idk so don't take this as an answer

[slender elbow]

like, only making a stream just to call findFirst?

[shadow night]

Not my problem then lol

[slender elbow]

no

[worthy yarrow]

let me show you hold on

[visual tide]

If your application is very performance-dependent then you probably want to benchmark it yourself, for your specific use-case

[worthy yarrow]

Eh was just wondering cuz fourteen said use iterator not streams

[slender elbow]

eh

[worthy yarrow]

(at least in this specific case)

I'm trying to find the bit he was referring to hold on

[visual tide]

Using streams is not gonna kill your performance

[paper viper]

yeah use streams when they are convienant

[slender elbow]

i mean, unless it's stupidly hot code, it really doesn't matter

SequencedCollection#getFirst() 😌

[worthy yarrow]

public class InviteService {

    private final Map<UUID, Set<InviteImpl>> invites;

    public InviteService() {

Idk you tell me if it's stupidly hot 🤷

[shadow night]

What about https://chatgpt.com/share/69b54453-1fbb-4198-b0a2-e509bd5d96bc

[worthy yarrow]

kek

[slender elbow]

by stupidly hot i mean code that has to run fast because it's in a code path that gets called really frequently and you need to get it out of there asap

[visual tide]

Naaaah youre fine

[paper viper]

Yeah

[tardy delta]

And still you are coding in Java..

[paper viper]

what

[slender elbow]

which can be just as fast as native code..?

null checks are absordly cheap, like, single clock cycle cheap

[shadow night]

it's better to not have a useless line of code than to have one

[slender elbow]

"you're still coding in java" like what's your point

[paper viper]

python can be just as fast as low level languages like C

[shadow night]

Doesn't java achieve near native speeds these days through JNI and whatever
replace JNI with JIT please

[slender elbow]

i mean the runtime quite literally compiles your code to native instructions

via JIT, not JNI but yeah

[shadow night]

Yeah right

Got that stuff mixed up, oops

[slender elbow]

and it very well does compete with languages that compile directly to machine code

[paper viper]

theres a tiny overhead for jni but its fine if in the end its better

[tall dragon]

talking about java performance this is rlly cool challenge https://github.com/gunnarmorling/1brc

someone managed 1.5seconds

[shadow night]

And then people claim java is slow

[tall dragon]

to parse 1billion line file

[paper viper]

https://github.com/gunnarmorling/1brc/blob/main/src/main/java/dev/morling/onebrc/CalculateAverage_jerrinot.java

this is crazy

[tall dragon]

lots of hacky stuff yea haha

[tardy delta]

congrats they call into native code 🎉

its all simd

[blazing ocean]

the thing is that can't be like a random thing, it has to be for their companies weird fucking use case

somebody doesn't just say "hey let's make a challenge to parse one billion rows"

and then do it in java

[tall dragon]

but it does showcase whats possible

[glossy laurel]

Is there some easier way to create commands without needing to register them in 3 different places?

[tall dragon]

by default.. no iirc

but u can add them directly to the commandmap like most people here

[worthy yarrow]

public abstract class Command extends BukkitCommand {

    public Command(String command, String[] aliases, String description, String permission) {
        super(command);
        this.setAliases(Arrays.asList(aliases));
        this.setDescription(description);
        this.setPermission(permission);

        try {
            Field field = Bukkit.getServer().getClass().getDeclaredField("commandMap");
            field.setAccessible(true);
            CommandMap map = (CommandMap) field.get(Bukkit.getServer());
            map.register(command, this);

        } catch (NoSuchFieldException | IllegalAccessException e){
            e.printStackTrace();
        }
    }

    @Override
    public boolean execute(CommandSender commandSender, String s, String[] strings) {
        execute(commandSender, strings);
        return false;
    }

    public abstract void execute(CommandSender sender, String[] args);

    @Override
    public List<String> tabComplete(CommandSender sender, String alias, String[] args) throws IllegalArgumentException {
        return onTabComplete(sender, args);
    }

    public abstract List<String> onTabComplete(CommandSender sender, String[] args);

}

This is what I do

[glossy laurel]

so like

[blazing ocean]

...or you could just use a command framework

[glossy laurel]

instead of letting the first (command, argument, whatever) be handled by bukkit, just handle it urself?

[tall dragon]

which does exactly the same under the hood

[glossy laurel]

how

[tall dragon]

no. all ur changing is how ur registering

ur registering directly into commandmap like nuclear is doing

but ur best off making a framework around that

or using one

[glossy laurel]

how do I do that

whats a framework

😭

[tall dragon]

for example aikar's command framework allows commands made like so

https://github.com/aikar/commands

[late abyss]

Is there a difference between reading my plugin's config during onLoad or onEnable?

[worthy yarrow]

onLoad is on server startup after depends ofc, and onEnable is after world has been loaded right?

[blazing ocean]

Util.sendMsg is crazy

i would've understood if it was minimessage or something

[tall dragon]

straight from their wiki 😂 ¯_(ツ)_/¯

[glossy laurel]

wot?

what does this even do

[tall dragon]

it adds a command

[late abyss]

I see, thanks! So if I don't need to interact with anything during the config parsing, it's save to put it in onLoad.

[worthy yarrow]

well given that this is true, it depends on what needs to read your config either onLoad or onEnable @late abyss

[tall dragon]

if u wanna know how it works u should read their docs

[glossy laurel]

Holy im so confused lmao

[tall dragon]

well if u wanna keep it simple. what nuclear sent here allows u to register commands into the commandmap

so u dont have to register anywhere else

[slate siren]

I tested the code here and I think I didn't explain the system I wanted clearly. The system here works like this.

It calculates the damage dealt to the player, and when doing this calculation, the power of the sword, the armor the player is wearing, and everything else are taken into account.

But this was not the system I wanted. Let me explain it very briefly and concisely.

First of all, let me state this, the power of the player's sword or the armor he is wearing should not matter.

A player also has 10 hearts,
Now what we need to find out is this: Sometimes a player can be attacked by more than one player at the same time.What is important to us is the killer, (How many hearts did the killer use to kill this person?)

For example, 2 people hit that player at the same time and the murderer killed that player by taking 4 hearts. In this case, it should be reported as follows.

You killed the player named (....) with (4 hearts).

That's just it. I tried to do it, but I couldn't calculate how many hearts, i.e. how many HP, the killer actually took from the killed person when more than one player attacked at a time.

[glossy laurel]

Okay that almost makes sense

Nice

[worthy yarrow]

I can send you an example of how it's used if you need tha spoonfeed kek

public class IslandCommand extends Command {

    private final Skyblock plugin;

    public IslandCommand(Skyblock plugin) {
        super("island",
                new String[]{"is", "islands", "nsb"},
                "NormalSkyblock: Island command, Usage: </island, /is, /islands, /nsb",
                "nsb.command.island.use");
        this.plugin = plugin;
    }

    @Override
    public void execute(CommandSender sender, String[] args) {
        if (!(sender instanceof Player player)) {
            return;
        }
        GUIRegistry guiRegistry = plugin.getRegistryManager().getGuiRegistry();
        player.openInventory(guiRegistry.getOrThrow("role_settings_" + Role.VISITOR.name()));

    }

    @Override
    public List<String> onTabComplete(CommandSender sender, String[] args) {
        return null;
    }
}

...


// In your main or wherever you register commands 


@Override
    public void onEnable() {
        registerCommands();
    }


private void registerCommands(){
        new IslandCommand(this);
    }

[glossy laurel]

I more or less got it

Its fine

[worthy yarrow]

well there ya go

It's there if you need it

[glossy laurel]

Right

[tardy delta]

whats the plugin for

is there any good library or something for making inventory GUIs?

personally https://github.com/noxcrew/interfaces-kotlin is my favourite and you also use kotlin so

githuh.com is a thing????!???!!!

[blazing ocean]

apparently it's a 301 to github.com

[slender elbow]

barely a few do

if by "call into native code" you mean using Unsafe

unless reading the file is also calling into native code

then it's unavoidable 🤯

the claim that java is slow is so absurd

cool, gonna try it out later

[halcyon hemlock]

tick

[tardy delta]

write them in xml

thought id get a reaction

[dark moth]

forge,neoforge,fabric

throughout coidng and modding who do yall think alone is the honoured one

ima go with neo

[paper viper]

i really like fabric

[dark moth]

but i need that info

[paper viper]

id recommend neoforge or fabric

forge is kinda ehhhh

[dark moth]

ima code a mod for keybinding, tried with forge, gone wrong,dont try at home

[tardy delta]

write me a keyboard driver

[dark moth]

i hate forge

[paper viper]

i dislike it because the community has not had a good history

[normal thicket]

racists? pedos?

[dark moth]

they aint even that active bro

[paper viper]

No just straight up toxic

[dark moth]

HAH

[paper viper]

and jerks

[dark moth]

fno i hate it more

[normal thicket]

then it's okay I thought something interesting was happening there

[paper viper]

well lets put it this way

all of forge's original developers except for Lex joined neoforge

https://neoforged.net/news/theproject/

[tardy delta]

forgecord 💀

[dark moth]

is neo actuall goated

[paper viper]

"I want to be clear, Lex has been a problem in the modding community for many, many years. Almost every veteran minecraft modder has had a negative interaction with him over the past 12 years. I have, when able to, tried to steer people to not abandon Forge just because of Lex - defending him in many a private conversation with a frustrated modder who’d just been called a “C*nt” for 1,000th time by Lex, or banned from our online spaces for a trivial transgression like discussing Fabric or coremods."

[tardy delta]

curle and lex, damn we are getting a little story

sounds like a fairy tale

[dark moth]

crazy

[normal thicket]

why the fuck keeping shit like that around??

[eternal oxide]

Hes always been that way

[normal thicket]

just ban mf

[eternal oxide]

But forge was "his" project (I believe)

[paper viper]

so none of this rlly, but still doesn't mean you shouldnt move away

[chrome beacon]

yeah

[normal thicket]

oh fuck him if he's gonna be uneducated shitass he can leave it up his ass and keep it there

[dark moth]

thats what u meant by "having not a good hsitory ?"

[paper viper]

Yea

[dark moth]

i thought u were blaming out of nothing lol

[eternal oxide]

I was goign to start modding many years ago (7 to 8) but decided not to once I was banned by Lex.

[paper viper]

no there were lots of controversies and stuff

[dark moth]

reason

[normal thicket]

meteor client ahh dev

bro muted me cuz of nothing

[eternal oxide]

I posted in IRC that I imagined Lex had a huge pulsating vein on his forehead

[paper viper]

Lmao

and you still remember to this day? damn

[eternal oxide]

it was pretty much the only time I did speak in his IRC

[dark moth]

the problem is i couldnt find any neoforge tutorial

need help rq

[paper viper]

pretty much all the stuff you'd do for forge would work on neoforge

[dark moth]

oh

shit

[paper viper]

neoforge isnt hard fork right now

[dark moth]

im fckd up

[tardy delta]

what does hard fork mean

[dark moth]

dude i wanna give up on my modding project and go follow up a different way

[paper viper]

not relying on the upstream anymore for any updated commits, etc

basically being completely independent of the parent project you forked from

right now forge stuff works on neoforge because neoforge isnt a hard fork and maintains some compatability

its not like neoforge hard forked and revamped the system so forge mods wont work on it anymore

[hybrid trellis]

When making a skyblock server, should I make it so the island has the data like owner etc, so when a player wants to go to a island with a offline owner I just load the data?

[pure dagger]

hey quick question, how to regenerate a player ?

for example 2 hearts

or max health

[worthy yarrow]

Do you mean apply regeneration the potion effect?

Or set their health?

[misty garden]

hello you can send me the depencies for the Factions plugin ?

[worthy yarrow]

Yes here you go

I just copy pasted lol

It's a bit anyway

[eternal oxide]

looks good to me

[worthy yarrow]

photographic memory doing me well

[pure dagger]

set their health, or add

[worthy yarrow]

Past 2 days been redoing maven structure for multiple modules kek

[pure dagger]

like damage but

wait... damage(-2)

im genius

jk

[worthy yarrow]

Anyways sorry for the bit, uh you should go to whatever factions plugin you're trying to get ahold of's git repo and see if they have their dependency information listed somewhere

[tardy delta]

love it when i get to patch a function again that already broke five times

[pure dagger]

@worthy yarrow do you know?

[worthy yarrow]

Oh sorry

player has a .setHealth method that takes a double

[pure dagger]

umm

but how do i add the health? how do i get player health for example

oh i can get tht

actually, how do i get his max health?

[worthy yarrow]

.getHealth

Oh

[tardy delta]

maybe if you actually start using the docs

[worthy yarrow]

uh

Yeah that

[tardy delta]

attribute modifier

[frail willow]

How to use base64 to make a custom player head?

[pure dagger]

i dont know

[tardy delta]

you dont know how to use the docs?

[pure dagger]

i dont think it would be easier to find how to set player's health to their max but imma try

[ornate mantle]

anyone have any resources on rotational matrices? I want to spawn a particle on the right and left of where the player is looking at

Hey, I have this sign and I have a map scanner that spawns NPCs at the sign's location. One issue I keep running into is that the NPCs won't face the direction of the sign. Here's the code:

                    if (lines[2].equalsIgnoreCase("warrior")) {
                        if (sign.getBlock().getBlockData() instanceof Rotatable rotatable) sign.getLocation().setDirection(rotatable.getRotation().getDirection());
                        final WarriorKitNPC npc = new WarriorKitNPC(sign.getLocation());
                    } else if (lines[2].equalsIgnoreCase("archer")) {
                        if (sign.getBlock().getBlockData() instanceof Rotatable rotatable) sign.getLocation().setDirection(rotatable.getRotation().getDirection());
                        final ArcherKitNPC npc = new ArcherKitNPC(sign.getLocation());
                    }

        this.serverPlayer.setPos(new Vec3(location.getX(), location.getY(), location.getZ()).add(0.5, 0, 0.5));
        this.serverPlayer.setRot(location.getYaw() - 90, location.getPitch());
        this.serverPlayer.setYHeadRot(location.getYaw());```
```java
        NMSUtil.sendPacket(player, new ClientboundRotateHeadPacket(this.serverPlayer, (byte) (this.serverPlayer.getYRot() * 256.0F / 360.0F)));
        NMSUtil.sendPacket(player, new ClientboundMoveEntityPacket.Rot(this.serverPlayer.getId(), (byte) (this.serverPlayer.getYRot() * 256.0F / 360.0F), (byte) (this.serverPlayer.getXRot() * 256.0F / 360.0F), true));
        NMSUtil.sendPacket(player, new ClientboundSetEntityDataPacket(this.serverPlayer.getId(), List.of(new SynchedEntityData.DataValue<>(17, EntityDataSerializers.BYTE, (byte) 127))));

Hi! Just a question. Will the "Recipe" provided by this event always be a ShapedRecipe, or could it be another type of recipe?

Thanks 🐱

[young knoll]

Could be shapeless

Or complex

[rugged fern]

can i get full mapping method names and not just these a,b,c? was it with the spigot or mojang mappings?

[young knoll]

Mojang

[inner mulch]

how are client-server systems usually designed? (all the packet stuff)

[young knoll]

They just

Send packets between eachother

If the packet is very important you could add verification that it made it successfully

(Or just let TCP do that for you)

[inner mulch]

what are packets? just a data class, and how does the client or the server know what to do with them?

[young knoll]

At their core they are just bytes

You’ll probably use the first byte(s) as some sort of ID so the receiver knows what to do with it

[silver hearth]

is this compatible with bedrock realms?

[inner mulch]

do you think it is smart, to have normal classes in a commonly shared module?

instead of just bytes?

[young knoll]

Well they have to be serialized to bytes either way

[inner mulch]

okay

[grim hound]

How do proxies transfer players between servers?

And how do they reinitiate the packet login process each time?

[remote swallow]

is what?

spigot?

[grim hound]

If you just cache exactly what the player sent when joining the proxy, then what about the player's responses to custom backend packets?

And how do you know exactly when to resend each packet for each version?

[young knoll]

When a player transfers servers on a proxy

The client thinks it’s a world transfer

Or at least it used to

And then the proxy changes which backend server it redirects packets to/from

[inner mulch]

since when can you do something like that with generics in methods?

[tender shard]

at least since java 8

[grim hound]

Holy mother of god

[inner mulch]

i have never seen some1 use this

i didnt know this was a thing xd

[unique shuttle]

Thanks 🐱

[inner mulch]

did you also not know this?

[grim hound]

Yeeee, do they now fully support restating the entire protocol, now that there's the Transfer handshaking intention

Also, how the hell does the client know when to send it

And when is it even sent?

Also, does the client resend any packets during a world change?

Cuz the server sure does

[grim hound]

Very much

[tender shard]

there's one place in spigot where that's also used, but I don't remember where. choco probably knows

it was some weird util class or sth

[river oracle]

Now look at nms

Prepare to cry

[inner mulch]

why :(

[tender shard]

found it

[young knoll]

I think you can put the client back into the config state and it’ll figure things out

Maybe?

[inner mulch]

to many generics

[rugged fern]

What did i wrong here? ServerPlayer entityPlayer = ((CraftPlayer) player).getHandle(); the error says Caused by: java.lang.NoSuchMethodError: 'net.minecraft.server.level.ServerPlayer org.bukkit.craftbukkit.v1_21_R1.entity.CraftPlayer.getHandle()'

[young knoll]

Seems like you didn’t reobfuscate

[stuck oar]

can anyone help

if (a.getInventory().getHelmet().getItemMeta().getLore().getLast().contains(ChatColor.stripColor("full set bonus".toLowerCase())) && a.getInventory().getChestplate().getItemMeta().getLore().getLast().contains(ChatColor.stripColor("full set bonus".toLowerCase())) && a.getInventory().getLeggings().getItemMeta().getLore().getLast().contains(ChatColor.stripColor("full set bonus".toLowerCase())) && a.getInventory().getBoots().getItemMeta().getLore().getLast().contains(ChatColor.stripColor("full set bonus".toLowerCase())))

I know its long but it just doesnt work

im trying to check if the player has the full set on

[carmine mica]

don't use lore to match against items

use pdc

[stuck oar]

if i use nbtitems it times out the server

anyway

the problem is

apparently the helmet doesnt exist

but it dies

does

[young knoll]

I smell 1.8

[carmine mica]

getLast
don't think so

[young knoll]

Then what is this nbtitems

[young knoll]

Clearly pandaspigot

[stuck oar]

good sense of smell

if i remove getLast it says "no armor equipped" if i add getFirst it gives the error again

im gonna tweak

[young knoll]

Why are you running stripColor on an uncoloured string

Or toLowerCase for that matter

[stuck oar]

idk

its 1m

1am

[stuck oar]

if i remove both of those it still doesnt work

[stuck oar]

nbt makes my server time out

[young knoll]

Then ur doing something wrong

[clear plaza]

How can I add a LibsDisguises dependency in my project?

[humble tulip]

There's this plugin called weapon mechanics https://www.spigotmc.org/resources/weaponmechanics-guns-in-minecraft-1-12-2-1-21.99913/

This plugin updates pdc of an item setting it without making the item pop back up on the item being updated

I tried doig the same by just reading a meta and modifying a pdc entry

However it causes the item to pop up

I'm frustrated cuz i have no idea why it works there

[lost matrix]

Simply prevent the item update to be sent to the client by intercepting packets

No need for the client to know all the pdc tags on an ItemStack

[lost matrix]

What dependency management are you using? Maven or Gradle?

[torn shuttle]

guys, I'm sorry to say, I cheated on spigot

I made a java plugin for a program other than spigot

but I swear it's for a good cause

it bypasses youtube's api so livestreamers can merge their chatrooms from different platforms into one chat on screen

[hybrid trellis]

When making skyblock, should I make it so islands have their own database, and a player has a key that helps when teleporting home, or depositing to bank? While island has the owner, members, bank, sign commands, etc

[lost matrix]

Properties for the island are stored in the island data, properties for a player are stored in the players data.

[lost matrix]

Are you planing on using a relational database or a document database?

[torn shuttle]

which one is the one where I manually write down the server state on a piece of paper?

[lost matrix]

[torn shuttle]

sounds like it would be a document

[hybrid turret]

does an event fire when a player regenerates hp?

[eternal oxide]

Javadocs have a handy search box, you could trying typing things like health https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityRegainHealthEvent.html

[hybrid turret]

Oh

I just saw it

i'm sorry ._.

sometimes my fingies are faster than my brain :(

[eternal oxide]

Its ok, people take a while to get used to the documentation

[echo basalt]

wrote that shit like forever ago

[eternal oxide]

search is a real BIG friend

[echo basalt]

works aite

but I made mine in node.js

[hybrid turret]

i've been coding for like 7 years 😭

i feel so bad lmao

[lost matrix]

I have a bit more than 4 now. Time flies 🥲

[hybrid turret]

only four? you doing this full time or why are you so good? lol

i'm doing it as a side hobby that sometimes gets more or less attention

[lost matrix]

Same, just as a hobby. Im still studying electrical engineering with a machine learning focus. So i write some C and Python there, nothing crazy.
I just went wild the first 2 years and i really like it. It replaced gaming for me 🙂

So happy that i got accepted at the TUM for my CS master in a few weeks

[glossy laurel]

How do I save a big list of blocks in the folder of the plugin? Preferably binary or something so it doesnt take too much space

[blazing ocean]

tbh i'd just run them through dfu and save to nbt

[rugged fern]

Can I somehow set what tve player caught by fishing?

[glossy laurel]

now in english 😅

[blazing ocean]

dfu is what minecraft uses for serialising stuff

[glossy laurel]

DataFixerUpper?

[blazing ocean]

yeah

but i think bukkit unsafe has some stuff for block serialisation?

lemme check

[glossy laurel]

Right, uhm, wanna spoonfeed me a lil?

[blazing ocean]

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[glossy laurel]

bukkit unsafe? 😭

[blazing ocean]

yeah no it doesn't have that

i'm sure there are better ways than through dfu tho, i'm not sure if blocks are codecified yet

[glossy laurel]

what the actual hell are you saying

😭

man, skript was easier lmfao

Right i got this

now tell me

what is "save to nbt"

bro nah, Named Binary Tag?

nah what's this bruh

@blazing ocean wanna send me some code? ☺️

[blazing ocean]

i've never really worked with serialising blocks, but do you mean a list of block states or materials

[echo basalt]

mfw smile is at my level with a third of the coding experience

[grizzled fog]

One message removed from a suspended account.

[glossy laurel]

All data about a block without it's cords, so that's block state right?

MongoDB I believe, not sure yet

So non relational

What does the boolean in Block.getState() do? Either i'm stupid af or it's not in the docs

[hazy parrot]

Where is boolean in block.getstate?

wthhh

[hybrid turret]

is it possible to define colors in the plugin.yml?

[blazing ocean]

wdym

[hybrid turret]

for example for the prefix

can i make the prefix displayed in the console colored?

[blazing ocean]

no

also please don't try to

it fucks up a lot of consoles and logs

• screenreaders too, probably

[hybrid turret]

sadge

[hybrid turret]

why is that?

[blazing ocean]

since you'd have to use ansi escape codes

and not all terminals and consoles support that

(and please don't even try to use chat colours)

[hybrid turret]

ah i see

[hybrid turret]

shhhhhhhhhhhh

only tried that with the logger

and that doesnt support colors

so generally, should all messages going to the console be un-colored?

(bc rn all of them are)

[blazing ocean]

yeah keeping them like that is probably the best option

[hybrid turret]

*colored

i mean

oops

    ConsoleCommandSender sender = Bukkit.getServer().getConsoleSender();

    sender.sendMessage(
      PREFIX + formatColors("&aEnabling &6" + getDescription().getName() + " &7with &6v" + getDescription().getVersion() + "&7.&r")
    );
``` something like that

[echo basalt]

mfw bedrock has components but no rgb support

[hybrid turret]

bedrock 💀

[hybrid turret]

or is this a nono?

[blazing ocean]

when i tried that i had the &s in my log

and that is not something that should br happening

[hybrid turret]

it's not the logger, it's using sendMessage

and it works fine

[blazing ocean]

yeah but in your servers latest.log

[hybrid turret]

oh the .log

i never thought of that

[blazing ocean]

...yeah

[hybrid turret]

[10:20:35] [Server thread/INFO]: [Admin] Enabling VanillaUtility with v1.2.0.

oh no

[blazing ocean]

you see now?

[hybrid turret]

can i strip colors for the console sender?

[blazing ocean]

those are the ansi escape codes

[hybrid turret]

oof

[hybrid turret]

so that users get colored stuff but the server doesn't

[blazing ocean]

just send users coloured messages, they support components

while the server logger doesn't fully

(i am aware paper has a component logger)

[hybrid turret]

i mean what if a user has a colored name
