[heavy mural]

By that you mean delay it through the setInterPolationDelay, by highering the value?

[rotund ravine]

Some javacord thing

[kindred gull]

how I fix that ?

[rotund ravine]

Idk, too lazy to look into it. DSeems to want a DelegateFactotyDelegate implementation

Also do note

Running javacord in onEnable and not async might be a bad idea

[hollow oxide]

i want to make a click listener and got this

import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerInteractEntityEvent;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.Bukkit;

public class ClickListener implements Listener {

    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        Action action = event.getAction();
        String playerName = event.getPlayer().getName();
        if (action == Action.LEFT_CLICK_AIR || action == Action.LEFT_CLICK_BLOCK)) {
            Bukkit.broadcastMessage("Le joueur " + playerName + " a effectué un clic gauche.");
        }
        else if (action == Action.LEFT_CLICK_AIR || action == Action.LEFT_CLICK_BLOCK) {
            Bukkit.broadcastMessage("Le joueur " + playerName + " a effectué un clic droit.");
        }
    }

and it's working on everything but mobs (and i want it to works on mob)

[rotund ravine]

It’s another event when you interact with entities

Also please compare enums properly

And not by their string name

[hollow oxide]

better?

[heavy mural]

Would I have to delay it by using a scheduler? 🤔

[hollow oxide]

got this too but not my code and idk how to make it works for left click

    @EventHandler
    public void onPlayerInteractEntity(PlayerInteractEntityEvent event) {
        Player player = event.getPlayer();
        Entity entity = event.getRightClicked();
        Bukkit.broadcastMessage("Le joueur " + player + " a fait"+ event.getEventName())
        if (entity != null) {
            player.sendMessage("Clic gauche sur une entité !");
        }
    }
}

[rotund ravine]

Look it up here

[heavy mural]

May anyone else take a look please?

[young knoll]

Yes

Idk exactly why but display entities just won’t interpolate the same tick they are spawned

[dry hazel]

my guess is that it uses SPI to discover something and that doesn't play nicely with relocation

[dry hazel]

it's just the login, it's fine

[slender elbow]

mfw DelegateFactoryDelegate

[heavy mural]

weird stuff

[dry hazel]

smh

d4j is love

[slender elbow]

true

[heavy mural]

Al right it works, just doesn't scale the way I want it sadly

it scales up from the corner to the entire size, but I wanted it to scale up from the middle towards both sides

[somber scarab]

I wanted to ask what is the most optimal way to store messages in my plugin?

I found it is very hard to keep track of all the cases where I need to send a message to a player or a list opf players or the whole serveror just the admins and each group has thier own messages that i will need and it just gets very messy

what's an efficient and clear way of storing messages

[rotund ravine]

There’s many ways

[somber scarab]

thank you! <.<

[umbral ridge]

how do you retrieve permission for specific command in plugin.yml?

Do I have to loop through the commands list and do something there?

[somber scarab]

player.hasPermission(String permission)

[umbral ridge]

xD that checks if player has a permission

[somber scarab]

what do you aim to do then? I may have misunderstood

[umbral ridge]

Can I retrieve this permission string from plugin.yml for specific command? eg.:

[brittle vapor]

I believe you will need to write your own handling for that, if you are trying to check the required permission for a command

[wet breach]

what kind of messages and for what purpose?

[somber scarab]

things like " you do not have permission to do that!"
" you need to be in a lobby first"
"player has invited you to a game"
and so on..

[umbral ridge]

ah.

[somber scarab]

and also need to dynamically add in the plugin prefix and the players' names

[brittle vapor]

"you are missing permissions <permission>" type thing?

[umbral ridge]

I'll just try to load plugin.yml as a config I guess?

if possible

[wet breach]

well, first you would categorize the messages. Error messages, info messages(can be sub categoried depending for who or where it came from). Once you do that, then you can create the variety of messages you want. But you only really need to store messages if you want them customizable or if you want to follow the Iln8 standard

[umbral ridge]

in each Command class eg. CommandAfk, CommandCraft, im checking if player.hasPermission() and right now what i have is this:

I want to have a command that retrieves permission string part from plugin.yml for that command

[brittle vapor]

You can have your command handling check if user has the required permission of the command being run, then return a message with the permission. But it all depends on how you handle your commands

[somber scarab]

Iln8?

[wet breach]

meant i18n

[umbral ridge]

hmm

[wet breach]

its a type of standard that allows messages to be swapped out easily for translating purposes. So you would have one file per language etc

[brittle vapor]

Sadly I cannot verify so I can't send screenshots

[somber scarab]

ah yea exactly what I need

the plugin comes default as english, anyone can edit the messages as they wish

[umbral ridge]

It appears I have to load plugin.yml as a config and load values from it

I think thats also the easiest way

[somber scarab]

I believe ill save them in a config file then retrieve the one I need whenever

[brittle vapor]

Yeah... idk if thats the best way though

You need to spend time in writing a proper subcommand/command handling system

[somber scarab]

but How do I replace the %PLAYERNAME%, %SENDERNAME% and so on?

i guess ill reseach that

[brittle vapor]

And have the permission load as part of each registered command

[umbral ridge]

I have written this I just need to retrieve the permission part

xD

[brittle vapor]

So when you run a command, it can return your defined values

[brittle vapor]

DM me and show your command handling

[wet breach]

well instead of editing the messages directly, they would just provide a yml file with the language of their choice named appropriately with the two letter language identifier, then its a matter of them selecting the language they want by inputting it in the config, and then your plugin just searches for appropriate yaml file. If it can't find it, it can notify and default back to whatever is default. Same goes if any messages are missing

essentially all the yaml file structures would be identical, the only difference is which yaml file you are using

[umbral ridge]

What do you mean with command handling though? I have a class per command

[wet breach]

this allows you over time to provide translations as well as users to provide their own

[umbral ridge]

and in onEnable I do this

Simple as that xD

[heavy mural]

Is there a way in spigot to add some kind of information to an item_display entity in order to be able to remove that specific kind of item_display and not regular item_displays?

[somber scarab]

yeah..

that sounds like a good way to go

[wet breach]

[brittle vapor]

DM

[umbral ridge]

why

[brittle vapor]

Ok dw, I won't help you then 👍

[umbral ridge]

I dont need any more help, I asked how to retrieve permission string part from plugin.yml and you're asking me about my command handling

[lost matrix]

What even is a MinecraftScreenshot

You cant do that async obvsly

Because the world could change while the ray marches in another thread.
This would completely scramble the consistency

[brittle vapor]

Yes... because you are obviously trying to get the permission from a command, no? Retrieving it from plugin.yml isn't the best option... I am trying to help you, but you're being cocky asf 💀💀

[lost matrix]

Sure

[brittle vapor]

You either want help, or you don't... jeez

[lost matrix]

Chunk chunk = ...;
ChunkSnapshot snapshot = chunk.getSnapshot();

What size is your image?

Because this could take a few minutes to render

[pseudo hazel]

not that I know, you can make a wrapper class or something similar though, or they probably have a uuid

[lost matrix]

Ok a few hours in this case

Ah you are not doing any material calculations and dont have any light sources

But interesting idea to calculate a server side view of the player

[shadow night]

A what

So the server can spy on the client or what

Hmm

That's a simple client mod

Well, no

Both sided

Yeah

Packets are ass

[thin iris]

wait u can take a screenshot via spigot??

can i see the output

is MinecraftScreenshot something you made

will it be open source 👁️ id love to try it

[rotund ravine]

It’s not a real real screenshot, but more of a representation of what they should be seeing

[river oracle]

that's probably a better idea since you can process ChunkSnapshots asynchronously too

[thin iris]

i mean, i was gonna have some sort of this in my ml image plugin

[rotund ravine]

ml?

[thin iris]

machine learning

[river oracle]

the first interesting CMarco plugin

[rotund ravine]

So how does the bible correlate to this

[river oracle]

😈 hey marco if there is any plugin to make premium it'd be this one

screenshots you can then displayon maps etc would be a wild idea

[thin iris]

what

u have the picture

just put it on a map

[river oracle]

easier said than done

[hushed spindle]

its not possible for plugins to access screenshots right

unless you upload the screenshot somewhere first

[river oracle]

ofc not lol

[rotund ravine]

No

[hushed spindle]

but at that point you might as well just use imagemaps or smtn

[river oracle]

oh my you guys he is just doing lots of fucking math

[hushed spindle]

oh i see

that sounds like hell

[thin iris]

im a bit confused.. you write it as a png then save it in the data folder, so why cant you just access it lol?

[rotund ravine]

It’s missing the usual bible flair. I am dissappointed

[thin iris]

and put it on a map

oh..

i thought u meant a physical mc map

maps are easy

[hushed spindle]

when using multiple maps you could but you might as well let another map plugin do that

so if im getting this right you're basically constructing a screenshot, brother

insane, but very cool when pulled off

will the blocks themselves have textures or will you be doing solid colors for them

[rotund ravine]

He wants to have textures, but he’s lazy 100%

[sterile breach]

Hey, how to get commandmap/list of all commands in the server?

[rotund ravine]

?google

[undone axle]

Google your question before asking it:
https://www.google.com/

[hushed spindle]

might as well create a little rendering engine that constructs the minecraft blocks the player can see and make a literal screenshot with that with like lighting and stuff

unless thats what you're doing

[umbral ridge]

Answer: mainClass.getCommand("commandName").getPermission();

[rotund ravine]

Yes

[quaint mantle]

Hardcode is the case

;)

[rotund ravine]

It was there or intended to be there at some point https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Material.html#isTransparent()

Try and see if it was ever implemented 🤷🏽‍♂️ Else time to cry over an enumset with transparent shit ahaha

[slender elbow]

Contributions welcome

be the change you want to see in the world

[rotund ravine]

I mean it has an implementation of sort

?stash

[undone axle]

https://hub.spigotmc.org/stash/

[worldly ingot]

Hey that's my line :(

You can borrow it, it's okay

[slender elbow]

not

i own the copyright

[worldly ingot]

oh

okay

[rotund ravine]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/Material.java#6812,6817

Probably don’t need to?

[slender elbow]

i mean sure, the point is that it

does not have an implementation which is well linked to the underlying server
which is why it says contributions welcome

[worldly ingot]

[slender elbow]

im gonna

yeet

[rotund ravine]

@slender elbow I expect to see you implement it within a week

[worldly ingot]

Even ItemType doesn't move that method over

[rotund ravine]

Does not block light lol

Idk man

@worldly ingot ?

[slender elbow]

he is in fear

[worldly ingot]

I mean yeah probably. That's what the docs say lol

[shadow night]

How often do servers have a gpu

[opal carbon]

oh no

[shadow night]

You could make a server player with cmarcos thingy

[rotund ravine]

Sometimes

Ye

[worldly ingot]

Glass blocks also don't have to be transparent

It's a texture

[quaint mantle]

GPU used by render sections of servers or some ai

[worldly ingot]

According to the server however, they allow light to pass through, which is transparency

I know, which is what Material#isTransparent() is doing

Remember that Bukkit is a server API

[remote swallow]

what

no way

[shadow night]

just wait till it isn't

[slender elbow]

im gonna put bukkit-1.20.2-R0.1-SNAPSHOT.jar in my fabric folder

[rotund ravine]

Do it

[hasty prawn]

im sure that'll go well

[worldly ingot]

I dunno what to tell you. The implementation is correct

Not great, but it's accurate

But I use

private static final Set<Material> ALL_GLASS = EnumSet.copyOf(Arrays.stream(Material.values())
            .map(Enum::name)
            .filter(mat -> {
                return mat.endsWith("_GLASS") || mat.endsWith("_GLASS_PANE");
            })
            .map(Material::matchMaterial)
            .collect(Collectors.toSet()));

[remote swallow]

dont we have a tag

[rotund ravine]

No

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Tag.html

Just checked

🥲

[ancient plank]

Minecraft tags are very limited

[lost matrix]

private static final Set<Material> ALL_GLASS = EnumSet.copyOf(Arrays.stream(Material.values())
            .filter(mat -> mat.toString().contains("_GLASS"))
            .collect(Collectors.toSet()));

Shouldnt that be enough?

[ancient plank]

They only really exist when Mojang has need for them in vanilla, and even then idk when they need em cus the things you'd think would have tags don't

Ye it should

I was too lazy to change the endswith

I yoinked it from this channel

[lost matrix]

What about Material.GLASS thats also kinda left out

[desert tinsel]

is there any way to set item frame's content just for a specific player?

what packets?

[rotund ravine]

?protocol

Well that sucks

Probably some entity data packet

[desert tinsel]

so with protocollib?

[echo basalt]

It's the entity metadata

Index 7 iirc

[river oracle]

the fact you remember that is crazy

[alpine urchin]

still advisable to check wiki

and the history for the version you’re dealing with

cause i remember i had a long issue with someone where they reported issues but the actual issue is the index changed

by 1

over the versions

and thats the reason why it didnt work

[young knoll]

[kind coral]

hello everyone, i am trying to make a custom block plugin with rewards etc, its currently published on spigot etc. but i want to add WorldGuard support, i have tried visiting EngineHub discord but to be honest its pretty dead and their approach hasn't worked out for me

I currently have a custom flag called epicblocks-break which defaults to false and have a check that does this

public boolean canBreak(org.bukkit.Location bukkitLocation, Player player) {
            Location location = BukkitAdapter.adapt(bukkitLocation);
            World world = BukkitAdapter.adapt(bukkitLocation.getWorld());
            LocalPlayer localPlayer = WorldGuardPlugin.inst().wrapPlayer(player);

            boolean canBypass = WorldGuard.getInstance().getPlatform().getSessionManager().hasBypass(localPlayer, world);
            if (canBypass) {
                player.sendRichMessage("<red>can bypass");
                return true;
            }

            RegionContainer regionContainer = WorldGuard.getInstance().getPlatform().getRegionContainer();
            RegionQuery regionQuery = regionContainer.createQuery();

            return regionQuery.testState(location, localPlayer, STATIC_PLUGIN.getEpicBlocksFlag());
        }

The only problem is that this flag to work also needs the block-break allow flag and i need to cancel each event that doesn't match a custom block, sadly my tries have indeed failed and can't seem to get this to working AS EXPECTED, in my various implementations i got players to break custom blocks but couldn't break any other blocks in regions that didn't even have the flag to allow, tho they were inside a bigger region with it as allowed. can anyone help me?

this is whats in my BlockBreakEvent listener

Optional<PlacedBlock> placedBlockOptional = epicBlocks.getPlacedBlockManager().get(blockLocation);
        boolean isCustomBlock = placedBlockOptional.isPresent();

        if (epicBlocks.isWorldGuardHook() && !WorldGuardUtil.canBreak(blockLocation, player)) {
            if (isCustomBlock) blockBreakEvent.setCancelled(true);
            return;
        }

        if (placedBlockOptional.isEmpty()) return;
        PlacedBlock placedBlock = placedBlockOptional.get();

        if (!placedBlock.getCustomBlock().testRequirements(player, player.getInventory().getItemInMainHand()) && !player.hasPermission("epicblocks.bypass")) {
            blockBreakEvent.setCancelled(true);
            return;
        }

[rotund ravine]

I mean if the people who made the shit can’t help you👀 Don’t you think you are doing smth wrong

[kind coral]

i indeed tried their implementation but sadly it doesn't match the requirement i need

[desert tinsel]

what should I use here?

[kind coral]

players can only break the custom blocks and nothing else as they said and i allowed the block-break flag else it wouldn't even break the block because its more protection

[heavy mural]

Maybe NBT tags are a solution for this?

[umbral ridge]

hey

[slender elbow]

indeed

[umbral ridge]

what are the chances of concurrent yaml config modification??

does it happens when config is modified in the same tick multiple times? or how does that work

[river oracle]

why would you ever need to concurrently modify a yaml config

that error should never occur unless you are wildly misusing configuration files

[umbral ridge]

then why does exception for it exists? because it should never occur?

[river oracle]

because it could occur if someone is doing something dumb

[wet breach]

which exception? ConcurrentModificationException?

[river oracle]

exceptions are in place for unexpected behavior not expected behavior

[umbral ridge]

yeah

[wet breach]

that exception isn't specific to yaml files

[umbral ridge]

I mean to File in general I guess?

[wet breach]

that exception is thrown when something is modified conurrently that isn't supposed to be

[umbral ridge]

My question was how does it happen? If file is modified in the same millisecond? tick? How does that happen in Yaml?

[river oracle]

asynchronous processing

or more accurate concurrent modification

you really shouldn't need to worry about it as long as you don't well conccurently modify your configurations

[wet breach]

if you want to concurrently modify a yaml config there is two ways, you can modify the yaml config data in memory since yaml file contents are stored in memory, or you can create a memory mapped file object

however, snakeyaml does not support concurrently modification if I recall, so you may have to either modify this or use some other yaml library that would support such a thing

[umbral ridge]

no no I'm just patching things up so there won't be any unexpected errors. each player has its own config so i guess there shouldnt be any problems

[river oracle]

conccurently modifying a yaml file reeks of using it as a database

[slender elbow]

it isn't really to do with modifying a file, usually it's because you're misusing a collection (adding/removing items from a list/map/set etc while iterating it), but it could be anything, would need to see the stacktrace to see exactly what's throwing that

[river oracle]

please use a proper database at minimum SQLite, spigot provides the driver for you so you don't have to worry about jar size

[wet breach]

well it is a flat file storage, which is technically a form of DB albeit not very efficient one usually beyond a certain limit lol

[river oracle]

ironically most servers won't get big enough for it to cause problems, but still especially if the plugin is being released publicly doing something right is important

YAML is definitely far from a good storage format

[wet breach]

well it is a storage format, not sure what you mean it is far from it when it already does this

yaml is a super set of json

[umbral ridge]

When dealing with a larger amount of players and player data, is it still ok to use yaml? json/gson? or is sql server the best option?

[river oracle]

if you are doing data driven development YAML and JSON definitely have their uses their, but as an actual database its not ideal

[wet breach]

never said it was the best, just that it does meet the criteria in terms of flat file DB's lol

[river oracle]

json is really no better than yaml as a databse. Think about the scale of your data though. Data that is required for each player? That screams use a databse to me. Maybe you're saving some basic world data that maybe go with NBT. Not a lot of data to store you doubt their will be more than 20-30 entries JSON, YAML is fine enough seeing as you can parse it and just keep it in memory.

[wet breach]

you can easily store 1GB of data in yaml just fine

[umbral ridge]

Ok thanks :D

[wet breach]

but to do so you need to memory map it

however, if for some reason your data is getting this large and you insist on not using a normal DB

you could go with binary storage

that is mempory mapped

this is efficient enough if you do it right, that you can technically store 20million blocks of data and save it in 3 seconds and load it in 6

[river oracle]

I usually just use NBT for stuff stored on the world 🤷‍♂️ however when it comes to player data there is definitely going to be a better way than giving each player their own YAML file. While you probably could do as you say with YAML and storey a lot of data with a memory map. Why though when you could just use a Database.

[wet breach]

probably can do this faster since the numbers I have are about 6-7 years old from a test that was conducted

[wet breach]

easier for the end user if they don't have to set anything up prior

[river oracle]

something like SQLite is good for up to a few millions of entries no?

[wet breach]

it can be, but it is no more efficient then what I described with binary storage

[rough drift]

I need to store a block in a list, I tried storing both a Set<Location> and a Set<Vector> (using the block's int x y z) but it doesn't really seem to work, anyone got ideas?

[river oracle]

what using it for?

[wet breach]

turn it into a string

[rough drift]

what

[wet breach]

and save it as a string list instead

[rough drift]

Checking for some blocks in an event

It's not persistent so idgaf if it gets removed lol

[rough drift]

isn't that like inefficient

[wet breach]

if it isn't persistent then why do you need to store it?

[rough drift]

It needs to be stored for a lifetime, it's not persistent across restarts*

[wet breach]

for a lifetime?

o.O

[rough drift]

oh

wrong again

Like lifetime of a certain event, not forever 💀

[river oracle]

what's wrong with using a Location or int array

[wet breach]

ok, but why does it need to be stored then? Couldn't you just like keep it in memory?

[rough drift]

yeah storing it in a list

in memory

it's still storing

[wet breach]

List<Block> doesn't work?

[rough drift]

oh shit

I forgor that

[rough drift]

but list Location/Vector doesn't work fyi

[river oracle]

why

[rough drift]

no clue

[river oracle]

oh yeah locations are weird

[wet breach]

wonder if this would have worked List<Integer[][][]> 🤔

[rough drift]

no

I am not doing that

also

I don't think that'd be memory efficient

[river oracle]

why would oyu need a 3d array just use a int[] and enforce a length of 3

[wet breach]

because it terms of memory its more efficient

a 3d array allows each dimension to not have to be right next to each other in memory

[river oracle]

How

[wet breach]

where as a single dimension array it does

[rough drift]

that's only in languages which don't optimize 2D arrays

langs like C# use a 1D array and do the math under the hood for [x][y]

[inner mulch]

Hello, how can i use my own plugins classes in another plugin, like an api?

[wet breach]

ok, well 2d wasn't specified

[rough drift]

well it's also for 3D arrays

[young knoll]

ddfghfgh whats going on

[wet breach]

2d array would be the same as 3d, just 2dimensions. Each dimension can be in separate areas in memory

[young knoll]

Storing blocks in a map?

[rough drift]

still doesn't work though

[rough drift]

yeah

[wet breach]

so in terms of memory efficiency, a multi-dimension array is better if its able to be used then a single dimension array

[rough drift]

I need to do that temp

[young knoll]

As a key?

[slender elbow]

since when is memory fragmentation a good thing

[rough drift]

yeah

[rough drift]

^

[wet breach]

even mc uses multi-dimension arrays for location stuff

[young knoll]

The blocks location should work

However you could go down to a BlockVector

[wet breach]

this isn't memory fragmentation

[slender elbow]

you are not allowing it to be a contiguous blob in memory, so, yes, it is memory fragmentation

[wet breach]

no

[slender elbow]

okay

[wet breach]

but I am not going to explain something you don't understand either

[slender elbow]

lmfao

asshole

[wet breach]

yep

[slender elbow]

"why would i want to educate you"

"why would i want you to learn something"

[wet breach]

You can't guarantee contiguous space for everything, if there is not enough contiguous space for an array Java throws OOM

multi dimension arrays, each dimension doesn't not need to be right next to each

because there is a pointer for the next dimension if the next one is needed

[slender elbow]

the GC can move stuff around on the jvm heap

and will

[wet breach]

so each dimension can have its own contiguous space in different parts of the memory

[wet breach]

not always

[slender elbow]

yes it does when it needs memory

[wet breach]

anything touching native code can't be moved on the heap otherwise it gets a new pointer, hence why using JNI the GC will not touch that area of memory at all otherwise you get all kinds of errors on both sides because pointers changed

so no GC can't always move stuff

[slender elbow]

what does native code even have to do with anything

[wet breach]

most times it can because not everything is touching native code

[slender elbow]

this is jvm heap we're talking about

[wet breach]

indeed

and what I stated is true

[slender elbow]

and what i stated is true either

[wet breach]

no its not

[slender elbow]

lmfao

[wet breach]

you obviously don't understand how pointers work

Java is not an exception to this

[slender elbow]

i do understand how pointers work

[wet breach]

Java doesn't magically bend the rules of native stuff it can only work around it

[slender elbow]

you clearly don't understandd how the jvm heap works

[rough drift]

Hey lads

it was working

I just misunderstood an event

[river oracle]

now look what you did

be ashamed

[rough drift]

BlockRedstoneEvent only triggers for the source block

?nms

[undone axle]

https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[river oracle]

did you follow the steps at above link ^

[wet breach]

I understand it more then you do and there is only like 2-3 other people in this discord who probably have the same level of understanding as me

[slender elbow]

aren't you a bit too full of yourself

i think i know what i'm talking about

i think everyone here would appreciate it if you stopped being an asshole

just saying

[river oracle]

ladies I think we can settle this by just looking at JVM internals its time to get digging

[rough drift]

frostalf is right though

[slender elbow]

clearly he has the entirety of hotspot in his brain so no need for that

[rough drift]

my guy I don't think you understand that if there isn't enough space for an array it will crash

[wet breach]

I don't care what everyone thinks obviously

[slender elbow]

that's not the thing

[wet breach]

Emily believes the GC can touch native stuff and just move it around willy nilly

[rough drift]

well it can't

[wet breach]

I know this

[rough drift]

I mean it can edit the JVM's memory as it pleases

[slender elbow]

that is literally not what i said at all

[wet breach]

no

[slender elbow]

stop putting words in my mouth lmao

[rough drift]

I was left under the assumption that a process can change it's own memory as it pleases

[river oracle]

idk how tf the JVM works but that is true, whether the JVM enforces some kind of standard is the real question

if it doesn't ofc arbitrary memory editing would be possible

but I would see that as potentially dangerous

[wet breach]

it can to an extent, the issue is that when it comes to native stuff, pointers can't just change without stuff just dying. So anything in memory has a pointer, this includes any memory reserved for a process. You still need pointers to know where it is at in memory. If the GC starts moving around space that is for native stuff, the pointers will change and the native stuff won't know where it went because there is no way to tell it

[slender elbow]

the jvm has control over its own heap, if the heap itself has and needs X bytes available, but it is not available contiguously, it can and will move stuff around within the heap to make up that for that contiguous space

[wet breach]

so, instead, anything native is cordoned off from the GC until its done

the GC works around it

[rough drift]

ah yeah makes sense

[slender elbow]

ps: the jvm heap is contiguous, so if this can happen without reallocating the entire heap, it will

[river oracle]

wouldn't an array just be stored in the JVM heap though not native

[slender elbow]

it would

[wet breach]

it is only contiguous if Xmx and Xms are set to the same size, otherwise if its dynamic allocated this is not true

[slender elbow]

it will realloc as necessary, but it is true

there are entire papers about it

[wet breach]

also, if objects are large enough, they will sit outside of the heap as well

which is far worse then fragmented in heap

there is even a jvm flag for this to increase space for such things so you don't end up with objects outside of the heap

[wet breach]

Yes, but arrays are backed by an integer

however my point wasn't that an array couldn't be moved, just was correcting the belief that the GC has the ability to move anything in heap to anywhere it wants. Technically it does, but it doesn't do this for the reasons I stated

[rough drift]

I mean yeah I was talking about what it could do, not what it should do

[slender elbow]

anything within the jvm heap, it can and it will

[rough drift]

it probably won't

[slender elbow]

it depends on the circumstances

it doesn't do it arbitrarily every 3 seconds for no reason ofc

[wet breach]

demonstrate to me that a native code will not cause some kind of error if you move its pointer

[slender elbow]

no

[wet breach]

well if you can't do that then its not true that GC moves everything

so....

[slender elbow]

man you sure are annoying

this has nothing to do with native code, i am very much explicitly saying within the jvm heap

i don't have time for you

[onyx fjord]

🧌

[wet breach]

memory is memory

it doesn't change because of the process

would you demonstrate to me that the hardware of memory changed because Java reserved Addresses of the memory from one point to another? even though the address space between those points are reserved for java, java still has to specify where in between those points stuff is at

there is no way to tell some native code that a pointer changed

and therefore, Java and its GC will not move such things in its memory space if its for native use

Nice

have no idea

I don't use such things

[slender elbow]

if its for native use

except that it isn't

[wet breach]

depends, there is some things in java that are tied to native

anything IO for example

[slender elbow]

that lives outside of the jvm heap

[wet breach]

my point was clarifying that the GC does not move everything as you claimed and there is stuff it simply won't touch at all and for good reason

[slender elbow]

🤓 ok sir yes sir

[wet breach]

Objects for IO don't live outside of the heap, although technically it could if maybe you had an insane amount of objects for a single stack

[slender elbow]

managed objects live inside the jvm heap, but the native buffers live off-heap

[wet breach]

Objects can end up outside of the heap

[slender elbow]

no they cannot

[wet breach]

there is even a JVM flag for this to help prevent that happening

[slender elbow]

prove it

[cinder abyss]

Hello, how can I get a random location in a radius with the player for center?

[wet breach]

alright, give me a moment to find the JVM flag

[cinder abyss]

like this
black dot is player,
red circle is possible locations

[eternal night]

Create vector with (n, 0, 0) and rotate it by a random number between [0, 2pi] around the y axis

the bukkit vector type has utilities for rotation around the y axis

[cinder abyss]

okay thanks

[grim hound]

can someone link me the mapping website again?

[eternal night]

https://mappings.cephx.dev/

[grim hound]

thanks

[grim hound]

and how can you search for a specific packet/class in there?

[cinder abyss]

what is your ide ?

[eternal night]

select the version and use the search field ?

[orchid gazelle]

2pi is the radians translation of 360° btw.

[grim hound]

and it'll show that class' changes throught all versions?

[eternal night]

its a mappings page

[grim hound]

ye?

[eternal night]

it has names

not source code or changes

[grim hound]

I know

but it does show

constructor and class name changes

[young knoll]

Yes

Those are names

[eternal night]

it shows you the names in the different mappings

if you mean "mappings" when you say versions

[grim hound]

I mean versions

[dry hazel]

there is a clock icon on every class page that you can click to have a cross-version overview of the class

[eternal night]

how do you know that huh

[dry hazel]

😝

[eternal night]

the old page was better

[orchid gazelle]

lynx, what is your favourite amount of degrees from 0-360?

[eternal night]

degree users are cringe

[slender elbow]

radian enjoyer

[eternal night]

for sure

[orchid gazelle]

then tell me in rads

[slender elbow]

epic

[orchid gazelle]

favourite from 0-2pi?

(90% of school in maths/physics here is degrees only)

[eternal night]

0pi obviously

[umbral ridge]

hi optic

hows your PCs? xD

[young knoll]

Few days late on that reply :p

[cinder abyss]

oh ok

[orchid gazelle]

no u

[cinder abyss]

like this?java Vector initialVector = new Vector(5, 0, 0); double randomAngle = ThreadLocalRandom.current().nextDouble(new Random().nextDouble(), 2 * Math.PI + 1); Vector rotatedVector = initialVector.rotateAroundY(randomAngle);

[orchid gazelle]

well that's a length of 5

do you want ANY place in the circle or with the specified radius of 5?

[cinder abyss]

specified radius of 5

[orchid gazelle]

ah ok

[cinder abyss]

If I want any place of the circle I do another random between center and max

[young knoll]

what is that random number selection code

[eternal night]

yea

[cinder abyss]

stackoverflow

[eternal night]

pls no

[cinder abyss]

https://stackoverflow.com/a/363692/22370494

[young knoll]

With threadLocalRandom can't you just do nextDouble(0, 2 * pi)

[eternal night]

Just ThreadLocalRandom.current().nextDouble(Math.PI * 2) is fine

[young knoll]

ah true 0 is the default min

[eternal night]

Or create a class-wide random instance

but the rest looks fine yea

[cinder abyss]

oh okay thanks

decompile minecraft no x)

[river oracle]

decompile the jar

that

[eternal night]

I mean

[river oracle]

is the only option

[cinder abyss]

https://mappings.cephx.dev/

[young knoll]

Buildtools already has that available for you

[cinder abyss]

You want the source package?

[young knoll]

In the work folder

[grim hound]

How can I get the window ID to send a spoofed PacketPlayOutWindowItems?

[river oracle]

I'm assuming window ID is container id

so ServerPlayer#containerId

[grim hound]

uh

[umbral ridge]

xD

welcome

[eternal night]

[cinder abyss]

Mojang : obfuscating code
Also Mojang : creating a mapping for developers

[grim hound]

I'm on spigot

so uh

[river oracle]

why are you using Spigot mappings

are you legacy?

[cinder abyss]

use Mojang Mappings 🔫

[grim hound]

I dunno how to answer that

[cinder abyss]

before 1.14

[grim hound]

nu

[river oracle]

before 1.17

[grim hound]

kinda

1.14+

[cinder abyss]

really?

[river oracle]

yes

specifically before 1.17.1 is when spigot support for mappings first came out

[cinder abyss]

oh okay

[river oracle]

doesn't mean its not possible simply means spigot didn't have mappings yet

so you'd have to make your own plugin to remap afaik

[young knoll]

Well they did

They have spigot mappings

[river oracle]

moj maps I meant

@young knoll moj maps PR when?

[grim hound]

can we get back to the topic?

on how to get the container id

[river oracle]

its a field in ServerPlayer

called containerId look at the obfuscated equivalent from the mappings site

[grim hound]

EntityPlayer, take it or leave it

[young knoll]

Yeah it'll be EntityPlayer.some letter

[grim hound]

can I just listen to some packets instead?

or can I retrieve it from the Inventory object?

[river oracle]

no

its not hard to use the mappings website

what version are you on

[young knoll]

1.14 plus

[eternal night]

[young knoll]

So it sounds like several

[river oracle]

containerCounter

that's the field

[wet breach]

TLABSize
MinTLABSize
TLABAllocationWeight
TLABWasteTargetPercent
TLABRefillWasteFraction
TLABWasteIncrement
GCDrainStackTargetSize
CodeCacheMinimumFreeSpace
MaxDirectMemorySize
UseMallocOnly
ZapJNIHandleArea

all of these are for controlling stuff that are outside of heap space, took a bit of time to find these since the darn list of options is huge now -.-

[river oracle]

obfuscated its cw

for vresion 1.14.4

[grim hound]

bruuuhh

[river oracle]

https://mappings.cephx.dev/1.14.4/net/minecraft/server/level/ServerPlayer.html do ctrl+f+"containerCounter"

[cinder abyss]

final code:

if (players.size() <= 2) {
  Player choosenPlayer = players.get(ThreadLocalRandom.current().nextInt(1));
            
  Vector initialVector = new Vector(5, 0, 0);
  double randomAngle = ThreadLocalRandom.current().nextDouble(Math.PI * 2);
  Vector rotatedVector = initialVector.rotateAroundY(randomAngle);
  return new Location(players.get(0).getWorld(),
    choosenPlayer.getLocation().getX(),
    choosenPlayer.getLocation().getY(),
    choosenPlayer.getLocation().getZ()).add(rotatedVector);
}```

[wet breach]

so after going through the JVM options lists, I came across that I forget there is a JVM option for self destructing after a pre-defined time

[young knoll]

Why are you remaking choosenPlayer.getLocation()

[river oracle]

lol so random

[cinder abyss]

I'll use Location instead of Player for the variable

[wet breach]

also you might like this one

[cinder abyss]

but is the code correct?

[wet breach]

ZapUnusedHeapArea - Zap unused heap space with 0xBAADBABE

[young knoll]

Looks like it'll work

[umbral ridge]

lol

[young knoll]

Correct may be another thing :p

[cinder abyss]

okay thanks

[wet breach]

oh also there is a jvm option to swap out the system time methods with fake timers

not that any of this info is probably useful to you

just a bit of curiousity

[river oracle]

wonder who this is useful to

[young knoll]

JVM developers I assume

[cinder abyss]

I modified .add(initialVector) by .add(rotatedVector)

I'm silly

[young knoll]

Don't think it matters

Bukkit vectors are mutable

[cinder abyss]

?

[young knoll]

If you add or rotate or multiply them

It'll modifiy the initial object rather than creating a new one

[quaint mantle]

hey can i spawn a zombie in the server, but make the client think it is a player

[young knoll]

Not super easily

But yes

[quaint mantle]

how would i do it?

[umbral ridge]

nice halloween hat

xD

[young knoll]

What version

[quaint mantle]

1.20.2

can i modify the outgoing clientboundpacket?

[young knoll]

Yes

[quaint mantle]

and just change the entityType to player

[young knoll]

In 1.20.2 players use the same spawn packet as other entities

So changing the type should be fine

[quaint mantle]

how would i catch the packet?

[alpine urchin]

yea

[young knoll]

Make a packet listener

Either via Netty directory or with PacketEvents/ProtocolLib

[quaint mantle]

when was this changed?

[young knoll]

1.20.2 I think

lol

[wet breach]

UseMallocOnly this jvm option which I listed above, removes heap space and uses only native space

maybe I should give this a try at some point as I haven't really tested what happens if you force MC to use native space only

[river oracle]

these are all some really weird falgs lol

[slender elbow]

that option no longer exist and neither does the zap jni handle area

[quaint mantle]

but it doesn't have to inject into the player right?

i just have to catch it from the server

right?

[young knoll]

I mean I think either way you inject into their connection

[quaint mantle]

but you inject to detect serverboundpackets right
not clientbound?

[young knoll]

Both

Everything is routed through the connection

[quaint mantle]

hmm ye, but do i "need" the connection
or is there a other / easier way

[wet breach]

to catch packets yes, you need a connection otherwise where are you going to be catching packets?

clientbound packets are packets that are heading out to the client, and server bound is from client to server, you can listen for either and catch either and do stuff with them before its sent or fully received(processed in this case)

or you can just swat them if you just don't want those packets leaving at all or being processed by the server XD

up to you in whatever is you are doing

[grim hound]

does anyone know what the last ItemStack is for?

[slender elbow]

it's the item on the player's cursor

[grim hound]

so like

when I'm spoofing the items

do I just input the constant

that's with the null material?

[slender elbow]

uh sure? if you want the cursor to be empty then passing the air item might do it, never messed with that

[upper hazel]

how do highest priority in eventHandler

[grim hound]

can you elaborate on what the cursor is?

[young knoll]

It's the cursor

[grim hound]

@EventHandler(priority = EventPriority.MONITOR)

[young knoll]

Yknow, the thing you move with your mouse

[upper hazel]

i mean @EventHandler(priority = EventPriority.HIGHEST, ignoreCancelled = true)
not work

[slender elbow]

when you click on an item, you hold it on your cursor

until you place it down or drop it etc

[grim hound]

so if you hold none it should be the empty item one?

got it

thanks

[slender elbow]

yeah prolly

[young knoll]

Yeah either air or null

Idk what the protcol expects

[slender elbow]

i don't think it'll like it being null lmao

[young knoll]

Ah yeah it does do operations on it

[grim hound]

not null

the material will be null

this one

[slender elbow]

that's the one yeah

[upper hazel]

this not worked((

[grim hound]

wdym?

[young knoll]

?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.

[upper hazel]

I'm trying to block another same event in another plugin

[young knoll]

what

[grim hound]

what

[upper hazel]

i try cancel BlockBreakEvent but this not cancl cuse another plugin use it

[quiet ice]

Incredibly random question, but is CMPXCHG16B for 64 bit values or does it also support 128+ bit stuff?

[grim hound]

what

like

[upper hazel]

what?

[grim hound]

does somebody really use event.setCancelled(false)?

like the plugin uncancels the event?

[young knoll]

I mean it's possible

Doubt it happens much

[ivory sleet]

iirc 64 yeah?

And sometimes 128

[quiet ice]

Then why is it suffixed with 16B - wouldn't that entail 128 bits at 8 bits a byte?

[ivory sleet]

Actually yes you’re right

(I think lol)

[peak depot]

whats the right bungeecord event for getting the player on intial server connect

[wet breach]

https://www.felixcloutier.com/x86/cmpxchg8b:cmpxchg16b

[quiet ice]

Yeah, but that suggests it's either or

[wet breach]

no it doesn't

look at the order

[quiet ice]

Ah bruh, it's two different insns

I may have a slight case of severe brain damage

[wet breach]

lol

[quiet ice]

Now I only need to randomly stumble uppon the ARM equivalent and I'm set for really stupid stuff.
Or well, I could use GCC and hope it uses the right equivalent but what is the fun in that?

[cinder abyss]

Hello, when NamespacedKey was introduced?

[quiet ice]

Uh, long enough for it to be not of an issue?

[cinder abyss]

if think 1.14

[quiet ice]

I wish there was some javadoc site for ancient bukkit versions that was compiled with modern Java

[wet breach]

DWCAS on ARM is done with double-width LL/SC instructions

[hushed spindle]

how intense are raytraces to servers, like if i do a relatively short trace of a couple blocks every tick for maybe a couple players is that a big deal or nah

[mighty acorn]

Anybody can help me here?

My Plugin always says Vault not found even its installed.

[quiet ice]

Nope, it's been there since 1.12 according to https://helpch.at/docs/1.12/ versus https://helpch.at/docs/1.11.2/

[hushed spindle]

is it your plugin or is it just chunky

if its your plugin show the code for vault detection

otherwise we cant help you

[grim hound]

is there a way to set an ItemMeta's display name to an empty string?

[hushed spindle]

yeah just make it empty

""

[mighty acorn]

Chunky is my Plugin and it says it cant find Vault

[grim hound]

nope

doesn't work

[hushed spindle]

try just a color code then

or like a 0-width space

[hushed spindle]

ok then show your code

and if you plan to publish it consider picking a different name because chunky is already a widely used plugin

[grim hound]

I can't

since I want it to be the heritage for an anvil input

and I want the input to be empty

[hushed spindle]

then 0-width space?

[mighty acorn]

Thanks but will only be used privatly

[grim hound]

?

[hushed spindle]

a space with 0 width

like

​

​

select whats in that box and you got a 0 width space

[grim hound]

​

[eternal oxide]

U+200B

[grim hound]

dassick

thanks

it won't be detected by String#isEmpty right?

[hushed spindle]

might wanna double check if that displays properly in minecraft tho

nope because its a character

it just has 0 width

[wet breach]

because its 16 bytes, there is 4 bits per byte, thus giving you 64bits, the instruction here is for double width so 128 bits because 16bytes:16bytes. The other instruction 8b is 8 bytes, double width gives 64bits. 8b is primarily for if you are dealing with 32bit registers, like integers for example and it works from 64bit cpus, but is also handy when on a 32bit cpu as well. and 16b is only available on 64bit cpu's but handy if you need double the width or dealing with only 64bit registers

to give you further clarification

[grim hound]

fuck

it does not

display as widthless

[hushed spindle]

sad

[grim hound]

it's some weird symbol instead

[quiet ice]

hm, 4 bits per byte is something I haven't seen yet.

[hushed spindle]

why cant you use a color though

like even &r

[grim hound]

I mean

I'm opening an anvil gui

and the input is the renaming

and the primoridal input is inherited from the item's display name

so it will probably turn into

[wet breach]

I am tired lmao

16bytes = 128 bits

[grim hound]

\u00A7

[grim hound]

the equivalent of a paragraph

[hushed spindle]

if you're using the anvil just for text input stuff you might wanna consider using chat instead

[wet breach]

8bytes = 64bits they are double width

[grim hound]

the point is that I'm adding functionality

so tis a custom feature

[quiet ice]

Ah I thought I have just seen some low-level specifics that I have never been taught.

[wet breach]

lmao

I wish

[quiet ice]

But yeah, so it is what I assumed. I just each time confused the 64 bit and the 128bit variant as they are usually listed besides each other

[wet breach]

8b is used when dealing with 32bit registers or 32bit cpu. and 16b when dealing with 64bit registers which means 64bit cpu but that is a given 😛

and DWCAS has always been available in ARM as well, and its the instructions I gave above but in double width, so it shouldn't be hard to convert over for whatever you are trying XD

[quiet ice]

Yeah most AMD and Intel CPUs should support both instructions so I am not worried on that front

And those that do not support these instructions cannot support modern OSes anyways as it appears so

[wet breach]

ldrex/strex (ARMv6 and v7), and ldxr/stxr (ARM version 8)

[quiet ice]

I mean I don't need those instructions just yet - it was more of a nice to know question

[wet breach]

ah

well now you know

[cinder abyss]

okay thanks

[quiet ice]

Honestly I thought it was there for longer, but 1.12 was the time I started with bukkit so makes sense

[cinder abyss]

NamespacedKey -> 1.12
PDC -> 1.14

[cinder abyss]

it's old

(not you)

[hushed spindle]

RayTraceResult result = p.getWorld().rayTrace(p.getEyeLocation(), p.getEyeLocation().getDirection(), 5, FluidCollisionMode.NEVER,
                    true, 0, null);

how come this isnt hitting a block when im looking right at it? definitely under the 5 block radius

result.getHitBlock() returns null

[grim hound]

yo what the f-

listConstructor = listClazz.getConstructors()[0];

this threw an OutOfBounds error

[hushed spindle]

then it empty

[grim hound]

but it's a

constructor

array

so what the fuck

it must have some sort of constructor

anyone?

[slender elbow]

does listClazz represent an interface?

[grim hound]

nope

that's why I'm confused

[slender elbow]

what is it exactly?

[grim hound]

does

the fact that it's protected

exclude it?

[dry hazel]

what about getDeclaredConstructors

[cinder abyss]

maybe because it's protected

[grim hound]

oooh

yeah I'm sorry for swearing

okay now I'm mad confused

but

did not throw an error

but this did

[dry hazel]

what does the getMethod call do?

[grim hound]

this is the original

[grim hound]

gets the method

it didn't throw an error

only the call to it did

[dry hazel]

well what I wanted to know is what's in the getMethod method lol

[echo basalt]

you need to pass an instance to invoke the method on

just pass null if it's static

so invoke(null, item)

[grim hound]

oh yeah

[cinder abyss]

hello, how can I clone an entity at another location?

[eternal night]

not really possible with the api yet

[cinder abyss]

okay thanks

[grim hound]

tis the constructor

tis da erro

like which argument?

tis

the method

[rotund ravine]

What’s the nms create list thing

[grim hound]

I should mention that I got the classes FROM the existing constuctors

[grim hound]

this basically

[grim hound]

creates this

[rotund ravine]

What arguments does reflection say clazzConstructor takes?

[grim hound]

I'll debug em one sec

[cinder abyss]

???

[grim hound]

you need

[cinder abyss]

do someone have an explanation?

[grim hound]

to put a

class with the specified parameter type

[cinder abyss]

that's what I do?```java
public abstract class CustomMob<T> {
public T entity;
public HMobsType type;

public CustomMob(Class<T> entity) {
    this(entity, false);
}

public CustomMob(Class<T> entity, boolean silentSpawn) {
    this(entity, HMobsType.GENERIC, silentSpawn);
}

public CustomMob(Class<T> entity, HMobsType type, boolean silentSpawn){
    if(!entity.isInstance(Entity.class)) throw new IllegalStateException("T entity must be an Entity!");

    T spawned = SpawnMob.getRandomLocationWithinPlayers(new ArrayList<>(Bukkit.getOnlinePlayers()))
            .getWorld()
            .spawn(SpawnMob.getRandomLocationWithinPlayers(new ArrayList<>(Bukkit.getOnlinePlayers())),
                    entity, (pig) -> {
        pig.setCustomName("oliver193");
        pig.setCustomNameVisible(true);
});

...```

[lost matrix]

Both generic types are from different places

[cinder abyss]

hum

[lost matrix]

First of all: Make your fields private pls

[pseudo hazel]

why not just use Entity instead of T

[cinder abyss]

why?

[cinder abyss]

I'm modifying my code, I'll change that

[grim hound]

public net.minecraft.network.protocol.game.PacketPlayOutWindowItems(int,int,net.minecraft.core.NonNullList,net.minecraft.world.item.ItemStack) so as expected

[cinder abyss]

idk the difference between accessing variable and accessing function accessing variable

[lost matrix]

Because you never want other classes to have access to your fields.
Strong encapsulation is one of the most important principles to write robust code.

[cinder abyss]

oh okay

[pseudo hazel]

or atleast make them like final

[grim hound]

wait...

[grim hound]

it's probably this mfo

[lost matrix]

Lets see what the problem with your generics could be

[lost matrix]

Try to specifically define a call type for your method like this:

        T spawned = SpawnMob.getRandomLocationWithinPlayers(new ArrayList<>(Bukkit.getOnlinePlayers()))
                .getWorld()
                .<T>spawn(SpawnMob.getRandomLocationWithinPlayers(new ArrayList<>(Bukkit.getOnlinePlayers())),
                        entity, (pig) -> {
            pig.setCustomName("oliver193");
            pig.setCustomNameVisible(true);
        });

[grim hound]

just add extends Entity>

[cinder abyss]

okay thanks all!

[lost matrix]

You are going to have huge problems btw because you are getting the world from one player and then spawning the entity on another players location.
If those two are not in the same world, then an exception will be thrown.

[echo basalt]

why is bro spawning a pig with oliver's name

[cinder abyss]

https://blog.jeff-media.com/use-consumers-when-spawning-custom-entities/

code isn't finished

[cinder abyss]

I made a variable containing the Location
also, I do that:```java
public static Location getRandomLocationWithinPlayers(List<Player> players) {
List<Player> filteredPlayers = majoritary(players, Player::getWorld);
World world = filteredPlayers.get(0).getWorld();
...
}

....

public static <T, E> List<E> majoritary(List<E> elements, java.util.function.Function<E, T> classifier) {
Map<T, List<E>> grouped = elements.stream()
.collect(Collectors.groupingBy(classifier));

    return grouped.values().stream()
            .filter(list -> list.size() == grouped.values().stream()
                    .mapToInt(List::size)
                    .max()
                    .orElse(0))
            .flatMap(Collection::stream)
            .collect(Collectors.toList());
}```

[orchid gazelle]

dude that looks hacky asf lmao

[cinder abyss]

perfectly working 👍

[orchid gazelle]

great

[cinder abyss]

my code is working thanks

[pseudo hazel]

doesnt mean I understand whats going on though

[quaint mantle]

wiat where

oh

@jagged quail

[jagged quail]

who you calling a pig

[quaint mantle]

tbh it was mfnalex

where is that guy anyways

[grand flint]

it's not even oliver it's literally oliver193

paul has beef pork 🐷

how do u cross a word 😭

[lost matrix]

This code makes very little sense. Why are you only selecting locations from a world with the most players?

[quaint mantle]

h

[lost matrix]

This can also be shortened by quite a bit

[young knoll]

~~word~~

[lost matrix]

This saves you the nested stream:

  public static <T, E> List<E> majoritary(List<E> elements, Function<E, T> classifier) {
    return elements.stream()
        .collect(Collectors.groupingBy(classifier))
        .values().stream()
        .max(Comparator.comparingInt(List::size))
        .orElse(null);
  }

[heavy mural]

I have an entity item_display which I want a player to perceive to be at their Y level continously. Is this possible, without being too resource heavy?

[lost matrix]

With 1-20 players, the split and join would most certainly produce more overhead than just streaming this consecutively

Ive written a fork with some guys that had ~150 people on one instance with still 20 TPS

*Was 1.8 back then

[echo basalt]

just run minestom 🗿

[young knoll]

What on earth is this code

[umbral ridge]

I guess that's what paper is for xD

and other forks

[lost matrix]

Myeah. Really depends on what you are doing.
If its not survival then you can get 200 people on one 1.20 server without much optimizations.
In the end its just 200 entities with maybe 3x load resulting in effectively 600 entities. (Which you can handle with good hardware)

[echo basalt]

throwback to when I had 18k citizens npcs all wandering on a shared host

[lost matrix]

No thats not what paper is for

Their max load is pretty similar to spigots in that regard

[umbral ridge]

But it's more optimized yeah?

[lost matrix]

It handles a select amount of systems in a different manner.
Some might be more optimized, but in most cases this only matters for survival servers.
Do you know how to utilize the changes of this fork?

[umbral ridge]

Nope I don't use paper

[orchid gazelle]

intel i9-14900K*

On overclock plz

[umbral ridge]

I might start to use it though it would be nice to know

[orchid gazelle]

It would just take entity tick multithreading

[lost matrix]

Understanding the platform and optimizing your project for its purpose is much more important than choosing which fork you are using.
If you dont need entities, then dont spawn entities. If you dont need chunks from -64 to 256, then dont generate huge chunks. And so on.

[orchid gazelle]

We could easily make it happen at the cost of every second plugin breaking and it being harder to make plugins

[lost matrix]

Minestom already has multithreading capabilities and can def handle 250 players if not much is going on

The problem is that you need to reinvent the wheel, if you want to use it.

[orchid gazelle]

Yeah but that's running on C++

[umbral ridge]

I guess aikar flags count too, a few changes to spigot and bukkit files
