anyone remember off the top of their dome what java version was required to run mc 1.19?

I want to say 17? Or was that for older versions

[chrome beacon]

1.18 and 1.19 use java 17

[torn shuttle]

sounds about right thanks

[torn shuttle]

ah damn I hate it when that happens

[blazing ocean]

run gradle knows

[torn shuttle]

must be a weird plugin I'm using on gradle

[blazing ocean]

john is a bit silly

[torn shuttle]

weird

must be some weird gradle bug again

[cold pawn]

bump ^

[blazing ocean]

wtf

[torn shuttle]

yeah gradle is weird

[keen charm]

Hey

How can I achieve this with Gradle?

[torn shuttle]

I am pretty sure spigot has a sample gradle project, potentially even lower down in that page

[keen charm]

https://www.spigotmc.org/threads/spigot-bungeecord-1-17-1-17-1.510208/

I'm on here

And I don't seem to find one

[chrome beacon]

You need to use a 3rd party gradle plugin

[keen charm]

Is there one existing?

[chrome beacon]

https://github.com/patrick-choe/mojang-spigot-remapper

[runic pine]

how i create WorldMap object in coordinates without players click on map. basically i want to create some maps when the server turns on

[keen charm]

So I'm using a multi-module Gradle project

How can I make it so that it'll use the remapped jar instead of normal builded jar?

Or does it use the remapped jar by default?

[remote swallow]

Specify remapped

[keen charm]

This

Remapping from remapped-mojang to remapped-obf

What is the new version of ChatColor.translateAlternateColorCodes?

[lime wave]

how could I execute a function every 20 ticks?

[eternal night]

nothing?

[granite night]

oh so now i can send directly the message with the color format done?

[eternal night]

I mean

[wet breach]

if you use text components sure

but I think you misunderstand that method you speak of though

[eternal night]

Yea idk what you mean with "new". What is wrong with the current method

[wet breach]

translate alternate color codes just allows you to specify what is the character to indicate the start of a color code instead of it being MC default character

since its not a character easily found on a keyboard. Handy when you are dealing with config files for example

[granite night]

I want to use the normal & char to color my text. What should i do?

[wet breach]

I guess you don't read

[granite night]

I knew this one but it says that ChatColor is deprecated

[wet breach]

so I have no interest in further helping those that are illiterate

[granite night]

sorry I didn't read that message. I will search how to use text components

[pseudo hazel]

deprecated does not mean it cannot be used

[wet breach]

its not deprecated

[pseudo hazel]

its deprecated in paper

[wet breach]

paper might have it deprecated but spigot does not

[pseudo hazel]

but you are in spigot server

[wet breach]

therefore there is nothing they need to change

[eternal oxide]

ChatColor.translateAlternateColorCodes if you want to use &

[granite night]

Ok, thanks you all. Sorry if I bothered you.🙇‍♂️

[lime wave]

does anyone know how to execute a method every 20 ticks?

[eternal oxide]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[lime wave]

I've tried
Bukkit.getScheduler().runTaskTimer(this, this::load, 0L, 20L);

(load is my method) but it seems to mess with command blocks

or is it because load is taking a lot to compute?

[eternal oxide]

?nocode

[undone axle]

It’s hard to answer a programming question without code
Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.

[lime wave]

public void load() {
        Lmanager.diminuirTodos();
        Map<UUID, GUI> map = guiManager.getMap();
        for (UUID key : map.keySet() ) {
            Player player = Bukkit.getPlayer(key);
            assert player != null;
            if (player.getOpenInventory().getTopInventory() == guiManager.getMap().get(key).getInv()) {
                guiManager.update(player);
            }
        }
    }

public void update(Player player) {
        UUID uuid = player.getUniqueId();
        GUI temp = map.get(uuid);

        if (player.getOpenInventory().getTopInventory() != temp.getInv()) return;

        int page = temp.getPage();
        int sort = temp.getSort();

        map.replace(uuid, new GUI(player, page, sort));
        player.openInventory( map.get(uuid).getInv() );
    }

public void diminuirTodos() {
        leiloes.forEach(Leilao::diminuir);
        leiloes.forEach(leilao -> {if (leilao.getDuration() < 0) {leilao.finalizar();}});
        leiloes.removeIf(leilao -> (leilao.getDuration() < 0));
    }

[lime wave]

private Map<UUID, GUI> map = new HashMap<UUID, GUI>();

[eternal oxide]

ChatGPT code by the looks

[lime wave]

no, but a lot of people helped on doing it

and part of it is in portuguese (my language)

[eternal oxide]

don;t use assert for live code

why are you updating an inventory for every player every second?

[lime wave]

because the items of the inventory change

[eternal oxide]

player.getOpenInventory() will always return an Inventory instance, even after they close an innventory

it will be their own inventory if they don't have one open

[lime wave]

and the items are get from Lmanager's leiloes

[eternal oxide]

are you creating new items every time you call Lmanager?

[lime wave]

I've added == guiManager.getMap().get(key).getInv() to check if the inv is the GUI

[pseudo hazel]

wont this be null if the player inventory is used? player.getOpenInventory().getTopInventory()

[lime wave]

I just create a new GUI when the contents of Lmanagers change

[lime wave]

then it will return false when checked with == guiManager.getMap().get(key).getInv(), wouldn't it?

[pseudo hazel]

yeah I guess haha

[eternal oxide]

yes

[pseudo hazel]

my bad

[lime wave]

I guess there's prob a better way to do it

but what I'm trying to do is, call update() for every player that has the GUI open

and do that every 20 ticks

the items on that GUI are visual, the real ones are stored in Lmanager's leiloes

[lime wave]

leiloes is an ArrayList of Leilao

Leilao stores price, duration, bid and owner

[pseudo hazel]

tf is a leilao

ok

[lime wave]

auction

[pseudo hazel]

and what is the issue again?

[lime wave]

and every time the price, bid, or duration changes, it should affect for the items on the GUI, that should display the new time and all

[lime wave]

using:```java
Bukkit.getScheduler().runTaskTimer(this, this::load, 0L, 20L);

[lime wave]

load is responsible for updating the values on Lmanager, and calling update for all the gui's

[pseudo hazel]

where do you call this

[lime wave]

I've put this on onEnable

and load() is on main too

[lime wave]

here is load's code

[eternal oxide]

ok first, don;t compare every player to every inventory

your key is the players UUID, so just get the player from teh UUID, get the inventory (Map value) and see if it is the player current open inventory

[summer scroll]

This is my attempt to make player glow with colors but the glow is just white even tho I set the team color to blue or something, what went wrong?

    public static void setGlow(Player player, ChatColor color) {
        // Get the team and set the color first
        Team team = find(player);
        team.setColor(color);
        // Set the player to glowing
        player.setGlowing(true);
        // Set player to glow
        player.addPotionEffect(new PotionEffect(PotionEffectType.GLOWING, Integer.MAX_VALUE, 0, false, false, false));
    }

[eternal oxide]

oh ignore me. I'nm not reading yrou code correctly

[lime wave]

is there a way to remove UUID from the map once the inventory got closed?

[eternal oxide]

yes, remove it on teh inventory close event

[lime wave]

does it handle leaving from the game, dying and all?

[pseudo hazel]

yeah

anytime an inventory closes

[alpine urchin]

i'd test and account for these situations, especially leaving the game

[grim hound]

How can I get the craftbukkit version regex?

this

cuz on newer versions they removed it

[remote swallow]

paper moment

[grim hound]

and there's always an issue whenever I try to get it

[remote swallow]

use Bukkit.get some version and map it

[grim hound]

1.20.1-R0.1-SNAPSHOT is what Bukkit.getBukkitVersion returns for example

[grim hound]

But I'm not sure what R1 is

[shadow night]

In CVN we use this

/**
     * Returns the old CraftBukkit location, no longer here after <b>Paper</b> 1.20.5
     * @return Something like v1_20_R3 or null if it is not relocated
     */
    public static @Nullable String getCBOldNotation(CVN plugin) {
        if(isNewCBPackages(plugin)) return null;
        String craftBukkitPackage = Bukkit.getServer().getClass().getPackage().getName();
        try {
            return craftBukkitPackage.substring(craftBukkitPackage.lastIndexOf('.') + 1);
        } catch (IndexOutOfBoundsException e) {
            return null;
        }
    }```

[remote swallow]

why have 2 different methods

[shadow night]

Changes when the API changes on a patch version iirc

[remote swallow]

Bukkit.get some version existsed for ages so you just map it for all versions

[remote swallow]

mojang thing, basically changes when protocol compact changes

[shadow night]

Btw that was written by @cinder abyss blame him

[clear elm]

how can i get a zombie spawner as a itemstack

does the noteblock physics update happen clientside? cancelling BlockPhysicsEvent seems to flash the noteblock for a tick

[hazy spade]

can someone help me i bought plugin
but its not for 1.21 only for 1.20.4 and idk when itll get update
cant i somehow update it myself

[humble tulip]

you can

do you know java?

[mint nova]

Player player = (Player) event.getWhoClicked();
        Location x = plugin.getConfig().getLocation("location.test1.x");
        Location y = plugin.getConfig().getLocation("location.test1.y");
        Location z = plugin.getConfig().getLocation("location.test1.z");

        Location location = new Location(player.getWorld(), x, y, z);

What im doing wrong?

[humble tulip]

x,y and z

are not Locations

configs can save locations btw

[tardy delta]

those are doubles

[mint nova]

so i need convert to doubles? in config.yml

[torn shuttle]

prepare for trouble and make it double

[humble tulip]

config.set("path", Location);

[mint nova]

location:
  test1:
    x: 10
    y: 1000
    z: 10
  test2:
    x: 1000
    y: 10
    z: 1000
```\

[mint nova]

Oh

[humble tulip]

config.getLocation("path");

[mint nova]

so i need to create location and then set the x y z from config?

[humble tulip]

ofc you can also do it yourelf if you don't need to save the world and pitch and yaw

[mint nova]

ok i will try now thanks

[granite night]

How do you translate Hex codes(example: &#084CFB)?

[humble tulip]

    private static final Pattern pattern = Pattern.compile("#[a-fA-F0-9]{6}");

    public static String translate(String message) {
        Matcher matcher = pattern.matcher(message);
        while (matcher.find()) {
            String hexCode = message.substring(matcher.start(), matcher.end());
            String replaceSharp = hexCode.replace('#', 'x');

            char[] ch = replaceSharp.toCharArray();
            StringBuilder builder = new StringBuilder();
            for (char c : ch) {
                builder.append("&").append(c);
            }

            message = message.replace(hexCode, builder.toString());
            matcher = pattern.matcher(message);
        }
        return ChatColor.translateAlternateColorCodes('&', message);
    }

Hey

If we run a task async instead of sync, does it get run later than the sync one?

[humble tulip]

Not necessarily

[wicked beacon]

hey guys I'm new here, one question do yall think it would be possible to make a plugin with the same idea this mod has, and if so it would probably be using packets which ones https://www.curseforge.com/minecraft/mc-mods/gravitychanger

they're pretty cool actually

I approve

neat, now I can do this for hundreds of these files

[grim hound]

No key layers in MapLike[{}] pops up on my custom world loading

what is it caused by?

[echo basalt]

it won't work because it static

unless.. you init it for no reason

to load the static values

mad hatters gonna hat

[vestal trout]

why am i in the world "world" when registering first time? at the second time i'm in register world, but for the first?????

code

[remote swallow]

lang is null so its being teleported to home.LappyTon not locations.register

or well other way round

[obtuse hedge]

whats the best performant way to check when a player has walked into a area and also exited?

[humble tulip]

Well playermove event

But you can also use worldguard

[vestal trout]

home.Lappy is just login world.

[humble tulip]

Which also uses playermoveevent iirc

[obtuse hedge]

im not using worldguard

[drowsy helm]

Player move event , but I think worldguard uses some sort of spanning tree to optimise getting area

[vestal trout]

first of all server checks if player have picked language, then password, so home.LappyTon basically dont make any usage

I still teleport to the "world" world

[vestal trout]

damnn this bug is so annoying

[obtuse hedge]

i dont use wg so ill try that

[keen charm]

Hey. I'm sending a player remove packet, and when I go far away from the player that I removed and come back, I don't see that player anymore. For this, I listen to add entity packet, add the player again, then remove it. But the issue is if I do that, although I see the player, their skin is reset to one of the default skins instead of their previous skin. How can I fix it?

https://pastes.dev/3X1hAxGuUR

This is how I do it

[inner mulch]

Why are u using packets instead of Player#hideEntity

[keen charm]

Because I don't want to completely hide the player

I just want to remove them from tab list

Since UPDATE_LISTED doesn't exist in old versions like 1.18.2 I have to do it like this

Here is the video of the situation: https://streamable.com/kczpk9

By the way, Steve is the custom skin I set here

And the other skin that appears when the player becomes visible to my test account is one of the default skins which I never wanted to use or specified in my code

Any ideas on what am I doing wrong?

[obtuse hedge]

where is the best place I can host my pack for free for the longest time

so I can use it in my server

[remote swallow]

host ur own http server

[pseudo hazel]

github

Host it urself

[obtuse hedge]

github

why do you want to use plib

it sucks

i dont want to

but like 5 plugins i use

need it

or they dont work

and these 5 plugins are very essential to me

Hey

Is running runTaskLater in a chain ok?

[torn badge]

Sure

[keen charm]

For instance, does this seem good?

[eternal oxide]

If scheduling inside a running task you need to add +1 to the delay or it runs on the same tick.

[keen charm]

So the delays would go up like 1, 2, 3 for each task in chain?

[eternal oxide]

2,3,4

if you do 1 inside a running task it gets added to teh end of the queue and runs at teh end of the tick

[keen charm]

Got it

[keen charm]

Also the issue is if I do it like this it works, even if it runs in the same tick

But if I run all of them in the same task it doesn't work

[eternal oxide]

yes it will work, but your first task runs in teh same tick as teh outer task

[urban crest]

im new to java, can someone help me compile this code in eclipse?

[grim hound]

packets

[obtuse hedge]

bruh

ah helllll nahhhhh

[quaint mantle]

[grim hound]

yo, can you remake that for a 32-bit integer?

well I guess I can just use it as is

but have you tested the performance of it compared to a normal concurrent hash map?

[quiet ice]

Well using the same algo means supporting 30-bit ints at most

[grim hound]

mmm I guess I'll just go with this one

[quiet ice]

https://tenor.com/view/seriously-laugh-laughing-you-serious-jk-simmons-gif-6107729

[grim hound]

to me it just looks like

funky magic

[quiet ice]

that's just a spin loop

[grim hound]

no idea what the fuq this does

what does even Thread.yield do

[grim hound]

so you mean that it's much faster?

[quiet ice]

it's a NOP by default, but otherwise it will tell the scheduler "hey, I'm blocking - you can swap the currently active thread"

[grim hound]

uh

[quiet ice]

The while ((ctrl = this.ctrl) < 0) loop basically waits until a resizing operation has completed. After that it will try to increase the amount of threads currently accessing the bucket

[grim hound]

how does that work exactly?

[quiet ice]

I don't know but it's basically meant to stop a thread consuming too much CPU time in low-core systems even though it's blocking on other threads that aren't currently running.

[shadow night]

wtf are those words

[quiet ice]

On systems with a lot of cores you can just use a generic NOP though. To be honest that line was a bit of a premature optimization from mine

[grim hound]

if it made it faster

it's good

it's not some premature ejaculation

nor optimization

it's just good

[quiet ice]

I trust JIT to do it's job there. If JIT deems it to be superfluous then it can turn it in a NOP, otherwise it'll do a syscall to the OS which might not be exactly free

However benchmarking asynchronous resizing operations isn't exactly the easiest thing in the world

[grim hound]

what's NOP tho?

[quiet ice]

no-operation - i.e. nothing

[humble tulip]

No op

No operation

[grim hound]

but how does that work?

swapping the currently active thread?

[humble tulip]

Threads ≠ cores

Sometimes multiple threads are on a single core

So a single core has to do the work of multiple threads

[quiet ice]

I don't want to go through the messy details of java threads versus OS threads versus CPU threads

[humble tulip]

That tells the cpu that its doing nothing

So you can probably switch to another thread

[grim hound]

how does that work tho?

[compact arch]

I was wondering if anyone has had any problems with Inventory events for 1.21? It seems like they are completely broken. I've tested my entire codebase with 1.20 and everything works fine, but as soon as I depend on spigot-api:1.21-R0.1-SNAPSHOT this part of code breaks.

Even running something simple to test throws an exception:

@EventHandler
public void onInventoryClose(InventoryCloseEvent event) {
  System.out.println(event.getView().getTitle());
}

Any suggestions? Or this is a genuine bug in the Spigot API?

[humble tulip]

Os magic

[quiet ice]

Thread#yield probably (albeit indirectly) sends a signal to the CPU to tell it to switch contexts.

[remote swallow]

sounds like your trying to extend inventory view

or implement it

[grim hound]

I'm asking surface level

[echo basalt]

redacting the package name

[humble tulip]

See geol

[echo basalt]

my boy either works at hypixel or he thinks he's a spy agent

[remote swallow]

the exact error is your api version is 1.21 so you have an interface inventory view but your on 1.16.5

a) update b) dont extend/implement inventory view

[quiet ice]

It likely won't be much different compared to how try-catch blocks work (or other signals such as SIGKILL, etc.)

[compact arch]

The plugin supports 1.16 - 1.20 fine. But implementing 1.21 seems to be troublesome

[compact arch]

I implement Listener specifically. Has there been a major change in 1.21 that I'm not aware of?

[remote swallow]

do you use nms

[quiet ice]

You need to compile for the lowest version you support

Compiling for higher versions means it uses INVOKEINTERFACE instead of INVOKEVIRTUAL, which older versions of spigot will be super confused about.

[compact arch]

For testing or for dependencies?

[slender elbow]

while (blah)
Thread.onSpinWait();
:3

[remote swallow]

do you phsyically interact with nms in the project

[compact arch]

Hmm I see. So you'd suggest splitting the plugin into two, one for 1.16-1.20 and one for 1.21+?

[compact arch]

Nope

Nothing uses nms imports. Everything relies on the Spigot API

[quiet ice]

That's the other thing I've been thinking about. Ultimately I lack the knowledge of these low-level specifics to know what is the better approach, although onSpinWait will probably be a bit more appropriate for spin wait loops :p

[remote swallow]

use the 1.16.5 spigot api and you dont have to interact with anything else

spigot is designed to be forward compat so you just have to write the plugin to the lowest version you support and bukkit handles the rest

[grim hound]

what the hell is that

[quiet ice]

In most cases, no.

[compact arch]

Hmm I see. So just change my dependency to use 1.16.5, and it will handle the rest?

[remote swallow]

yeah

[compact arch]

kk I'll give that a try

[slender elbow]

yeahh I don't know either, I'm more weary of using yield and oSW lol, although it's not like I use those often either so, touche

[quiet ice]

A different kind of Thread#yield() which has a different connotation (while Thread#yield() is a definitive demand to yield the process time to another thread, onSpinWait is a bit more subtle)

[slender elbow]

but also, like, if you're doing spin wait loops, it sounds like you could/should be using conditions or some other locking & signaling mechanism

latches or phasers or what have you

but sometimes it's cheaper to not do that

[grim hound]

these could even be cached for max performance

[quiet ice]

Neither are things I have ever used beforehand

[compact arch]

Ok cool that seems to work! Thanks for the help

[quiet ice]

what being cached?

[grim hound]

the big negation

[quiet ice]

~INT_62_BITS will get inlined by javac - no point in caching that

[grim hound]

right?

[grim hound]

ah okay

[compact arch]

Must have been related to what geol mentioned with how higher versions handle invoking during build

[grim hound]

from how I'm looking at it

this class seems to be some extra super fine optimized stuff

the resizing not being possible is a bit trouble but not something I can't manage

[quiet ice]

It resizes the buckets themselves, just not the amount of buckets as that would mean locking and rehasing the entire datastructure which would also mean more spin wait loops and thus quite a bit more performance waste if one already can anticipate the size of the collection

[grim hound]

so it does support holding more elements than defined at construction time?

[slender elbow]

that's why I preallocate my hash maps with Integer.MAX_VALUE 💪💪

[quiet ice]

Yeah, read the javadocs - it documents some extremely important quirks with this structure

And shrinking the datastructure is pure stupidity (not even ConcurrentHashMap does that from what I know)

https://stianloader.org/jd/org.stianloader/stianloader-concurrent/0.1.0-a20240212/org/stianloader/concurrent/ConcurrentInt62Set.html being the javadocs if you prefer reading them that way

[grim hound]

I was planning on holding like 1 << 20 buckets

[slender elbow]

that's a lot of buckets

[grim hound]

I'm reading them rn

[grim hound]

it's how much elements I expect

[grim hound]

would that have any performance impacts?

like gc constantly checking for reachability of each of these

[quiet ice]

Well the iteration time would be absolutely wreck for one

[slender elbow]

generally speaking, I don't worry about the gc, more often than not they do far better work than you think they do

[grim hound]

in the int62 class?

[grim hound]

okay

trust em

[quiet ice]

Yeah, it's iterator would need to go through 16 Million longs if nothing is resized

[grim hound]

worry not

I'm not iterating

just add, remove & contains

[grim hound]

also not 16 mil

it's 1 mil

[quiet ice]

It stores no less than 16 elements iirc

[grim hound]

each bucket?

[quiet ice]

The size of each bucket increases exponentially in factors of two with a starting size of 16 elements

[grim hound]

damn

[grim hound]

mmm

I see

isn't that

134 MB

of RAM

nice

[quiet ice]

Also just as a quick test before you use this datastructure: What is the most important quirk of this structure? That is, with which inputs would the performance of this structure be reduced to a minimum?

[young knoll]

12

[quiet ice]

I probably should be bolding that line too - perhaps even have it be present in there more than once because I'm quite sure I made that mistake in one of my applications, too

[quiet ice]

Oh yep, I absolutely do.

How the fuck is it still faster than a synchronized LongOpenHashSet? I urgently need to redo my benchmarks there

[grim hound]

I'm

[quiet ice]

Correct.

[grim hound]

yeah but

does this just mean

that storing 30-bit

or lesser-bit numbers is more beneficial somehow?

[grim hound]

You're surprised that your data structure is faster that an externally synced longopenhashset?

[quiet ice]

Oh, I didn't read the fine-print correctly. Good thing we have self-explanatory source code.

[minor garnet]

does anyone know how to get a vector direction based on the pose rotation of a armor stand pose?

Example:

pitch, yaw, roll

Vector3f pose = armorStand#setHeadPose(45, 90, 20);

pose -> vector direction

[grim hound]

https://stackoverflow.com/questions/2782647/how-to-get-yaw-pitch-and-roll-from-a-3d-vector

[grim hound]

oh you want to do the reverse?

no idea

[quiet ice]

It means that if you have 16 buckets for example (albeit rather extreme):

0x0000
0x0010
0x0020
…
0xFFF0

all get stored in the same bucket (see https://github.com/stianloader/stianloader-concurrent/blob/main/src/main/java/org/stianloader/concurrent/ConcurrentInt62Set.java#L71-L73). So if you don't have enough entropy at the lower bits, all (or most) of your values could fall into the same bucket, resulting in the structure just being a fancy concurrent ArrayList

[grim hound]

I mean I'll be saving pretty random 32-bit ints

each one will be unique

[quiet ice]

However, if your values are completely random (especially in the lower bits - though more bits will be used the more buckets you are making use of, so for 1 << 20 the 20 least significant bits are relevant) it's not too important

[grim hound]

I might do 1 << 19 as that's still enough for me

[minor garnet]

i want get a vector direction from a armor stand body pose

[minor garnet]

/summon armor_stand ~ ~ ~ {Pose:{Head:[47f,37f,0f]}}
example
https://haselkern.com/Minecraft-ArmorStand/

[grim hound]

I won't be using the most significant 32 bits

[grim hound]

how does that sound to performance?

[quiet ice]

Probably good

[grim hound]

aight ;]

[grim hound]

this is how bukkit does it but without roll

what even is roll?

wait I guess I can imagine what it is

[quiet ice]

You should be doing more aviation :p

[minor garnet]

this wont work because it doesn't consider the z of the stand armor pose

[quiet ice]

Anyways, I'll sign off for the day. Cya tomorrow I guess?

[grim hound]

cya

[hard radish]

is using Dependency Injection recommended?

ive read through it but I still dont really get how DI works (dumb brain)

[chrome beacon]

Yes

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[wet breach]

Yes because that is how oop works or is done. However it does depend on the purpose of the class. Utility classes for example should not rely on outside objects and should be independent.

If the object is some kind of management object you probably dont want to use DI either

[drowsy helm]

To put it simply, it’s just passing required classes (for instance main plugin class) through either the constructor or a method rather than getting it statically

[inner mulch]

when i have something that is always the same, for example the index of chest slots, should i store them in a final array or calculate them?

my case:
i want to know what slot indexes are in the first row of a chest (0-8). Should i just hardcode that or write a simple function calculating all these numbers?

[quaint mantle]

I want to do double jump. But I couldn't code the double jump left, right and back except the front. vector etx. I added it but it didn't work, I added char to the W, A S and D keys and that didn't work either. Can anyone help?

[inner mulch]

what?

im not sure what u r doing, but you cant get user input like with a mod, when creating a spigot plugin

[quaint mantle]

i want to double jump in every direction

[remote swallow]

easiest way would be just doing it with what way there looking

[quaint mantle]

how can you look back and double jump backwards? Instead I want it to double jump while going backwards.

i tried hard but it didn't work :/

[inner mulch]

player.setVelocity(player.getVelocity().multiply(number of your choice));

[quaint mantle]

u mean adding char right?

[inner mulch]

wdym char

you cant multiply something by a char

[quaint mantle]

i wanna make a doublejump but work like this; when player clicking; w,a,s,d it will jump according to the keys you press

it won't matter where you look

[inner mulch]

okay but you are not making a mod

you cant get player input

[quaint mantle]

so there is no method for this?

with spigot

[sullen marlin]

the client doesnt send keypresses to the server

it only sends movement

[inner mulch]

ive sent the closest thing you can get to achieving that like 10 messages prior

[inner mulch]

.

[quaint mantle]

can I get it up when it walks to the right or left?

[inner mulch]

no

[quaint mantle]

behind?

[inner mulch]

unless you have a definition of what that is

there is no universal left and right

[sullen marlin]

well it'd be relative to what they're facing

so you could use trigonometry/linear algebra

[quaint mantle]

aigt i will

[drowsy helm]

Ideally youd have an immutable list

But something as simple as first row is fine to calculate

[inner mulch]

i thought of hard coding too, but then i remembered there are invs that have rows with 3 width

or some weird ones

like anvil

[drowsy helm]

Eh thats really a case by case basis

Would have ti abstract it

[inner mulch]

my idea was to take the inv size as param

the width and height

[drowsy helm]

How would width and height work for an anvil?

[inner mulch]

anvil has height of 1 and width 3

[drowsy helm]

I would just take inventory type

Because youd have to define the width and height of every inv anyway

[inner mulch]

alright, thanks

[modern peak]

i need help with vaultapi

[sullen marlin]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[modern peak]

I made the integration of vaultapi in my plugin but when I start it, it does not find the plugin, I have maven configured, the plugin vault and essentials on the server.

when debugging I could only find this
[21:46:11 INFO]: [OnyxSpawners] Enabling OnyxSpawners v1.0-SNAPSHOT

which makes no sense because the plugins are loaded, vault as depend and essentials as softdepend so that it loads before my plugin.

try removing the essentials softdepend

if it tries to load before vault is registered, its going to cause issues

Why not just use an armorstand then

[drowsy helm]

[lime wave]

is there a way to add items to the inventory of a player that is currently offline?

[humble tulip]

not via api no

but there are ways yes

[lime wave]

how so?

[humble tulip]

Google invsee offline players

Might find a plugin that does it

Essentially loading up the players save file

You can use nbt api OR nms

[hard radish]

is it wrong to have private final Core plugin = Core.getInstance(); in most things that i need to call my main class for?

I know a lot of people do private final Core plugin; and do public something(Core plugin) { this.plugin = plugin }

what is this reason to do the second way?

[halcyon hemlock]

I've been programming for 4 years and still don't know

That's the reason I hate java

[hard radish]

😂

like all the open source plugins i saw uses the second method im just questioning myself

[halcyon hemlock]

Half the code is design patterns and the other half is more design patterns to comply

[halcyon hemlock]

Just use the first one

Works perfectly fine

[wet breach]

Second way is proper oop. The first way should really only be used for utility classes, classes that need singleton or similar. When dealing with genericness or universal type setups.

In personal projects or super small plugins probably wont really matter which you use lol

[hard radish]

ah ok

[mortal vortex]

https://refactoring.guru/design-patterns/singleton

[fleet kraken]

I want to make a schedule for the players, I want it to analyze their inventory all the time, what is the most “performative” way to do this? Make a single scheduler and loop through all the players online or “attach” a scheduler to each player?

[drowsy helm]

one will be more performant

if you schedule multiple they're still gonna run synchronously in order so you're just adding more overhead between each iteration

[stark sierra]

not sure if this is just a minecraft thing or an argument im missing when spawning a particle, but how come when I spawn FLAME or SMALL_FLAME it just flies off in one direction as opposed to being stationary?

hello i am using magma to make a forge spigot server and i want to use the items for exampel a gun from the mod in my pluign

can any one pls help

how i can do so

Hello,

I am using the spigot-1.19.4 api jar, but I cannot seem to find these imports:

import net.md_5.bungee.api.chat.TextComponent;

Anyone know if they have been removed? I know this is being pulled from bungee, so i'm assuming this has been removed?

I am upgrading from spigot-1.18 api jar to 1.19.4-api

[hard radish]

is it alright to put everything into a Dependency Injector? or just the things that I will have to use alot of?

[torn shuttle]

don't ask me

I have nothing to do with that

they stole my name, can you believe that

[drowsy helm]

okay spigooters

thoughts on incremental ores?

im thinking of adding an enchant which breaks both layers

[buoyant viper]

hmm

[drowsy helm]

or maybe diamond+ pickaxes break both layers

[blazing ocean]

that "current chat" widget looks exactly like mcci's lmao

[drowsy helm]

yeah because i copied it

[blazing ocean]

lmao

[torn shuttle]

should really not show the block being broken

it would make more sense to tie is such that the block damage animation progresses far more slowly and the ore is slowly knocked out of the block as you mine it

[drowsy helm]

its intended for an area where only the ores can be broken and once fulyl broken they turn into stone

then regenerate

so if players don't wait for them to fully regenerate, they get less overall coal

probably should've said that initially

[echo basalt]

gold, gold nugget, stone, gravel^?

hm

[drowsy helm]

yeah except no gravel

gravel ugly

[torn shuttle]

my point still stands

I think it would look better without it getting removed for a tick

[spice bough]

my plugin saves items when they in lava , cactus etc.
when i use my plugin on 1.20.4 with java 17 , i can see the items in lava or cactus
but when i use my plugin on 1.16.5 with java 11 or java 16 , yes plugin works, If I go to where the item is, it comes to my inventory
but i cant see the items. is this about java version or minecraft version

[dawn flower]

how do i open a villager inventory to a player?

(that they can trade with)

[summer scroll]

Player#openMerchant

[dawn flower]

without a villager actually existing

[summer scroll]

Yes, you can use that method.

[dawn flower]

that requires a villager / merchant object

[summer scroll]

You need to create a merchant and put the items.

[dawn flower]

aw

ok

[sterile breach]

Does Player#hidePlayer() remove player packets?

[sullen marlin]

Yes

[summer scroll]

Use Bukkit#createMerchant

[dawn flower]

:0

[sterile breach]

there is no utility to do it with with a packet library so?

[sullen marlin]

Likely the latter

[sullen marlin]

?

?xy

[undone axle]

https://xyproblem.info/

[dawn flower]

if spigot allows you to do it, why use packets

[sterile breach]

for a vanish plugin, in some cases, it's better to use packets rather than hideplayer?

[dawn flower]

no..?

[sterile breach]

I see a lot of vanish plugin than use packets

[dawn flower]

hideplayer literally does what y'll do with packets

[dawn flower]

either bad plugins or was made before hidePlayer

[eternal oxide]

hidePlayer literally limits teh packets sent

[sullen marlin]

Bad plugins, hidePlayer is at least 10 years old

[dawn flower]

oh god

[torn shuttle]

man I'm old

[dawn flower]

i didnt know it was that old

[torn shuttle]

10 years really

[dawn flower]

didnt u say ur username was like 10 or 20 years old or something

does createMerchant spawn a merchant or just creates it

[eternal oxide]

I remember when Magma first joined this discord

?

[eternal oxide]

to a degree maybe

matching items by name is never a good idea

[gilded turtle]

Then

?

[eternal oxide]

do a /data on the item to see what meta it has

Hm

So can I just use it even if it is not in vanilla mc?

[grim hound]

is there any way to access the jdk.internal Unsafe class?

cuz this method isn't in the sun.misc Unsafe

[quiet ice]

why on earth do you need to allocate such an array?

[grim hound]

just curious

I mean, if I override all of it's contents anyway

isn't this just a more performant way of doing so?

[quiet ice]

The JIT compiler exists and will assist you in that, there is no performance difference

Otherwise might as well use alloc + FFI

Especially the memory segment API might do what you intend to do here

[grim hound]

nah, I just need a byte array

[quiet ice]

it's a fancy byte array

Plus everything will be inlined anyways as it's built for speed

[grim hound]

well aight

just wondering why this is used

[quiet ice]

Most likely because string concatenation is a process that isn't exactly linear and the compiler might struggle with it

I'd not be surprised to see it gone in a few years though

[runic pine]

which more fast? switch with 100 cases or a map?

[torn shuttle]

benchmark it

[runic pine]

what would you do

[torn shuttle]

time it

[runic pine]

from what I researched map is O(1) and switch O(n)

[zealous osprey]

switch isn't O(n), or atleast from what I know. If I recall correctly, switches use something similarly to a map, since all the values are already hardcoded.

[quiet ice]

switch is O(1), too

Switch should be faster as it does not make use of any buckets or similar (at least not directly) and thus does not need to distribute hashes evenly

However an enummap or similar will result in the same performance as a switch, if not even better performance

[zealous osprey]

Most of the time you can just use if-statements, since the "compiler" will change them to switch statements if it can.
Switch statements just loop nicer often times if you are comparing enums imo

[torn shuttle]

that's why my plugin is nothing but 7000 lines of nested if statements

[quiet ice]

Having that much trust in the JIT compiler is a bit dangerous, too lol

[onyx fjord]

I'm having some issues with Player#setCooldown. Most items work but for some reason pearls dont and just ignore the cooldown

is there something special about them?

[eternal night]

Well, when do you set the cooldown on them

[onyx fjord]

on ProjectileLaunchEvent

[eternal night]

Yea, I mean, ender pearls have thier own cooldown

so the server will apply a cooldown of 20 ticks after that event

[onyx fjord]

so i wait a tick?

[eternal night]

pretty much

[sterile breach]

Is there a way to make mobs can't see a player? (Invisibilty effect don't work, mobs see you)

[sterile breach]

it also work for zombie focus?

[young knoll]

You can cancel it when the target is a player

[sterile breach]

whats the difference with EntityTargetEntityEvent?

[young knoll]

Only called for living entities

You can probably use the base event though

[sterile breach]

there is no living entities?

distribute your plugins in physical black boxes and rig them to blow up if decompiled

[blazing ocean]

based

[drowsy helm]

unless you have some ground breaking brand new technology theres not much point

[young knoll]

Write terrible code so anyone that decompiles it has a heart attack

[blazing ocean]

yes

[drowsy helm]

lol i dont even need to try

[eternal oxide]

coming next cloud hosted plugins

[blazing ocean]

works 100% of the time

[blazing ocean]

first are serverless minecraft servers

[bold rose]

also can anyonne guide me to start learn how to make/add license keys on plugins ? i tried to search but to no avail (+8yrs ago videos).

[torn shuttle]

those may run afoul of the spigot terms and conditions for premium plugins fyi

[drowsy helm]

is your alias cmarco by any chance

[runic pine]

i need clone an itemstack to call getInventory#addItem?

[blazing ocean]

you don't

[runic pine]

Is there a method to add an item to the inventory where the passed itemstack will be what is in the inventory?

[blazing ocean]

that is literally that metho

d

[mortal hare]

https://tenor.com/view/kronk-point-debate-argument-angel-gif-17274775

[blazing ocean]

@shadow night would know

[bold rose]

adding backdoors is probably much easier than generating license keys 👿

[runic pine]

but the method adds an ItemStack to the inventory but if you take an itemstack in that same slot it will return another instance

I wanted it to return the same instance

[blazing ocean]

it is just the same thing lol

[mortal hare]

i usually build bootleg API of brigadier but on bukkit api itself so i dont have to create manual processing myself

[mortal hare]

Although i havent done this before, but you can create this imo by:

• creating node.js/bun backend api server with express js or smth else (js frameworks are appearing day to day basis to account for that)
• creating spring boot web mvc backend api server
• creating php backend api server

the backend will check on HTTP POST request if license is valid (POST https://my-proprietary-plugin.com/api/license/check). it should return response (HTTP status 404 or 200) stating whether or not the license is valid. You can store validation keys in a database. This way you can further develop api further to revoke licenses, generate them, whatever you want.

from the plugin side it depends how proprietary you want it to be, you can use some advanced approaches which the plugin itself is not loaded by the plugin the maintainer provided to you, instead the plugin which was given to you downloads the real plugin from the same api, and loads it in memory only, thus if you want to pirate it, you need to dump its contents from memory, or reverse engineer the api which can be tricky.

or you can simply add some if statements that would disable the plugin if api check returned you a false response for a license. you do you.

☝️ I'm pretty sure this approach isn't available on spigotmc marketplace since it doesnt allow such DRM's (obfuscation only)

[quaint mantle]

Making paid home plugin with this one

[torn shuttle]

essentials, drm edition

costs an additional $40 on top of the regular price to maintain drm servers up

[blazing ocean]

php 💀
js 💀
no rust mentioned smh

[mortal hare]

what's wrong with js

[blazing ocean]

oh boy

a shit ton of stuff

[mortal hare]

dude its just an api which returns HTTP response code

are you really willing to code os dependant binary executable just to run your web server which returns 404 or 200

[torn shuttle]

that's a dumb question to be asking here

I've seen people do far more laborious things for much less gain

[blazing ocean]

yes

need a sanity check, why would this be false

[torn shuttle]

what's the code for the check

[shadow night]

At some point of writing terrible code the compiler starts improving it

[blazing ocean]

boundingBox.contains(player.location.toVector())

[mortal hare]

js is bad: proceeds to use vscode and discord client which is based on electron

hypocrisy

[blazing ocean]

i don't use vscode kekw

[shadow night]

Nobody here uses vscode

[mortal hare]

that status bar looks suspiciously like vscode's

[blazing ocean]

that's fucking IJ

[torn shuttle]

I've literally, unironically seen people abusing discord to use it for file hosting for their minecraft servers until they got spanked by discord

[shadow night]

That's IJ dumbass

[mortal hare]

mk

my bad

i haven't touched intellij for a while now

[blazing ocean]

🙏

@shadow night opinions on this tho

[shadow night]

what the fuck is thaz

[blazing ocean]

allows me to use if (player in boundingBox) ...

[shadow night]

weird shit

[blazing ocean]

nuh uh

kotlin has the same for lists lol

[torn shuttle]

I have a fun question that I feel like may make me some enemies

[blazing ocean]

go on

[torn shuttle]

is there a way to listen for some event or packet being sent from a server regarding sending a resource pack and blocking that

[blazing ocean]

client-side?

[torn shuttle]

server-side

[blazing ocean]

packetevents?

what are you trying to do

[torn shuttle]

block other plugins from sending resource packs

[blazing ocean]

PE probably does the job

[torn shuttle]

ok I don't have much experience with that

think it would be cancellable or something akin to that?

[keen charm]

👋

I'm trying to change a player's skin on join but if I try to join while the server is opening the skin doesn't change although the game profile value changes

If I re-join it works

Here is the video of the situation: https://streamable.com/lbjxf4

[mortal hare]

im pretty sure you need to send some kind of funky packet in order to reload the skin

i dont remember which one

[keen charm]

Possibly metadata packet?

[mortal hare]

not sure, try to look at skinsrestorer plugin source

maybe some kind of dimension packet

it basically fools client and it reloads the skin somehow

maybe my info is outdated now

but that's how iirc was done in 1.8 days

[keen charm]

But the thing is it only happens when joining when server is opening

If I re-join after that it works

[viral shell]

Hi, i made a fake player using EntityPlayer and player connection from CraftBukkit, now i have a problem, i don't know how to see if the player hits the fake player. This is because EntityDamageByEntity checks for damage and the fakePlayer isnt damagable, is there another way to see if the fakeplayer is hitted or to make the fakeplayer hittable?

[keen charm]

By the way, the thing is it only happens if I send a player remove packet

Although I delay it it doesn't work

I delay it by 5 ticks

[viral shell]

EntityPlayer bot = new EntityPlayer(((CraftServer) Bukkit.getServer()).getServer(), world, botProfile, new PlayerInteractManager(world)); way i made the bot

[chrome beacon]

You need to listen to the packets on your own

[mortal hare]

i wouldnt suggest you create npc's like this

the classes are not designed for such functionality

use packet manipulation instead

unless you want the npc to tick

[viral shell]

how i made it works, but i want it to make hittable

i want a way to see if a player hits it

also its is not a real "npc"

[mortal hare]

im pretty sure wiki.vg has a packet for hitting an entity

[viral shell]

i mean, its not made for the purpose to be an npc

[drowsy helm]

Interact packet is sent, you just have to get entity id

[mortal hare]

im not quite familiar with OBC so i cant really say for sure, but maybe is there a way to add damage from OBC itself

[viral shell]

I got it

So, this can be solved with an entityinteract event?

[mortal hare]

im pretty sure it should respond to that event

since it acts like a virtual player

[alpine urchin]

it depends if this npc is fake or not

i didnt read context

[viral shell]

its clientside

[alpine urchin]

then use packets

[mortal hare]

he created it via OBC

not packets

[alpine urchin]

then it’s not clientside

[mortal hare]

so it must be ticking, no?

[alpine urchin]

It depends

[mortal hare]

^^

[viral shell]

i should use other libs for that

[alpine urchin]

i would need to see how you spawn it

is it currently visible

[mortal hare]

what i dont like about this approach is that if player has the same name, server probably wouldnt allow for it to join if its ticking

[viral shell]

playerConnection.sendPacket(new PacketPlayOutPlayerInfo(PacketPlayOutPlayerInfo.EnumPlayerInfoAction.ADD_PLAYER, bot));
        playerConnection.sendPacket(new PacketPlayOutNamedEntitySpawn(bot));

[alpine urchin]

okay you spawn it usijg packets

meaning it’s fake

[viral shell]

random name

[alpine urchin]

you need to listen to interact packet

[viral shell]

yes

can it be done with pe?

[alpine urchin]

and then see if the entity id matches your npc’s id

Yes

[viral shell]

mh ok

[mortal hare]

tbh fake entities arent one size fits all solution, they're glitchy since they're not ticking, so if you unload the chunk or go to another dimension they they dissapear iirc

[viral shell]

i'm using them for ac purpose

[mortal hare]

[runic pine]

Unsupported class file major version 64. maven give me this error but im using java 22.why?

[wooden zodiac]

what I can i do to make my command remove player's name from tablist
i used gpt it just makes my player disappear

[chrome beacon]

what are you doing

also version 64 is java 20

not 22

[runic pine]

i cant send prints

i can send you on dm?

Hey

How can I access a player's GameProfile object pre-PlayerJoinEvent?

[grim hound]

packets

What's the most efficient way to execute a lot of tasks async? Let's say that even 3000 tasks per second to be scheduled

not waiting for anything, just purely executing on another thread

[tardy delta]

makes me question your design

[spice bough]

I want my plugin to work on all versions from 1.8 to 1.21.
q1 : which java version should i select here

[ivory sleet]

what kind of tasks

[slender elbow]

it depends on the nature of the tasks

[spice bough]

q2: which minecraft version should i select here

[tardy delta]

8?

assuming mc 1.8 uses java 8

[spice bough]

and which mc version should i select

[tardy delta]

i would just have modules per java version

[spice bough]

i think i dont need to select 1.8

[eternal oxide]

1.8 but supporting such a wide range is not easy

[grim hound]

Runnable

[slender elbow]

lol

[tardy delta]

still doing so

[slender elbow]

downloading 3 GB file is a runnable, as is calculating the Fibonacci sequence

as is doing 2 + 3

[ivory sleet]

mfw Runnable

[tardy delta]

ForkJoinTask

[grim hound]

basically

[spice bough]

for example if i select java 11, 16,17 or 20 plugin won't work correctly in 1.8 . is it true

it will work but with a lot of issues

[grim hound]

doing a few operations on a few maps

[grim hound]

but it's on the netty threads

so I'm not sure whether it's best to just schedule it

[grim hound]

(not on all packets tho)

[tardy delta]

we still have no idea what youre doing

🥸

[grim hound]

analysis

of the connections of players

for bot attack detection

[blazing ocean]

bro really doesn't like bots

[spice bough]

if i want my plugin to work from 1.16.5 to 1.21 which java version should i use?

[humble tulip]

Why does NMS use Holders?

[humble tulip]

1.16.5 java

Whatever version 1.16.5 is

[grim hound]

no idea, made me mad as well

[slender elbow]

online-mode=true is my favourite anti bot tool

[silent slate]

what item meta do i need for a firework star? how do i create a firework star that has "small ball green"?

[humble tulip]

I need to replace a holder

but creating one is so much pain

[grim hound]

this is precisely why I don't specify what I'm doing

[humble tulip]

like i dont even wanna replace the holder, just the thing it holds

[blazing ocean]

lol

[grim hound]

geol was right

[humble tulip]

OH I CAN JUST CHANGE WHAT THE HOLDER HOLDS WITH REFLECTION

im doing that

[slender elbow]

I mean we were more so asking what the tasks have to do but sure lol

[grim hound]

ye

[slender elbow]

not all holders hold a value directly

[silent slate]

.

[eternal night]

FireworkMeta ?

[silent slate]

but thats for firework rocket isnt it?

[spice bough]

so the plugin works properly in Java versions above the Java version I have chosen, but it does not work properly in those below it. is it true?

[humble tulip]

yes

same with spigot

well bukkit

[eternal night]

FireworkEffectMeta

sorry

[grim hound]

honestly, after talking here I think that making a thread for a few these might not be necessary

[humble tulip]

You code for the lowest version you plan to support

[spice bough]

so same thing here version

[humble tulip]

yep

[spice bough]

thanks.

wrong java version

[runic pine]

but i already compile this project with ajva 22

[tardy delta]

lemme just delete that

[runic pine]

how o fix @tardy delta

[eternal night]

[tardy delta]

i forgot

what plugin though?

compiling one from src or creating one?

[runic pine]

I think I've already fixed it

[eternal night]

cross posts in paper, does not read paper pings

[runic pine]

not is mine but i think i fixed

for some reason this error occurs if I use ArrayList.getFirst() instead of get(0) even when compiling with Java 22 (the IDE does not point out an error in the project, only this error when compiling)

[eternal night]

[tardy delta]

probably not compiling with java 22, check java version in pom.xml/gradle thing

[worldly ingot]

ArrayList#getFirst()?

[slender elbow]

sequenced collections!!!!!!

[worldly ingot]

Oh, right, sequenced collections

lol

[tardy delta]

thing in newer versions

[worldly ingot]

I forgot those existed now

[tardy delta]

sequenced collections 👀

whats that

[torn shuttle]

yeah I definitely know what that is

[eternal night]

.stream().findFirst()

[slender elbow]

collections that are sequenced

crazy

[eternal night]

[slender elbow]

iterator next

[tardy delta]

next step is to use kotlin

if

[river oracle]

Gonna die now

[torn shuttle]

speaking of looking good

it's leg day

bye losers

[eternal night]

my condolences

[torn shuttle]

have fun staying weak

[blazing ocean]

agreed

[torn shuttle]

I'll rack 300 on the leg press in your memory

[tardy delta]

you always lurking around?

[eternal night]

Hope that is in kg

[blazing ocean]

👀

i spawn whenever kotlin is mentioned

[torn shuttle]

of course

I'd do 400 but I've been on a cut for 6 months

[river oracle]

That's a shit load of weight in kgs wtf

[torn shuttle]

plus it's sets of 15

[eternal night]

300 is fine ™️

[torn shuttle]

300 isn't that much

[eternal night]

until you knee goes bye bye at a sport event

[torn shuttle]

I was almost at 400 before I started cutting

[river oracle]

Kekw wtf it's 5x my weight lo

[eternal night]

wtf

[torn shuttle]

it's 3x my bodyweight

well was

I'm down

originally I wanted to hit 450kg

but I'm definitely not doing that at 85kg and in sets of 15

[river oracle]

I've never even done leg press I can't imagine I can do much more than my bodyweight

[torn shuttle]

legs are your largest muscle

[eternal night]

Given you probably are not dying when doing a weightless squat, you probably can lol

[torn shuttle]

unless your knees are completely busted you probabably do more than bodyweight at some point in your day when getting up

[river oracle]

My knees are beyond fucked up

[torn shuttle]

cope and seethe, get better knees

[river oracle]

I wish 🙏 let me play basketball again

[eternal night]

Trust medicin, in 20 years we'll have cyberpunk knees

[river oracle]

It's my tendons in my knees 💀

Damn I forget how small lbs are compared to kilograms

My squat is 135 but that's only 61kgs

[torn shuttle]

61kg?

are you made of paper?

[eternal night]

magma gym shaming??

[river oracle]

Well I do only weigh 58kgs and I'm short

[eternal night]

Toxic community member spotted??
