[echo basalt]

The amount of nesting and unecessary checks just to get the closest player to a location

[sterile token]

agree

I would just make a custom user object, based on their uuid and then add a properties to that object

[woven tide]

ok ty

[sterile token]

Your welcome

[echo basalt]

private Entity getNearestEntity(Entity source, double minRange) {
  Entity result = null;
  double resultDistance = minRange*minRange;

  for(Entity other : source.getNearbyEntities(minRange, minRange, minRange)) {
    double distanceSquared = other.getLocation().distanceSquared(source.getLocation());

    if(distanceSquared < resultDistance) {
      resultDistance = distanceSquared;
      result = other;
    }
  }

  return result;
}

Player PDC is a thing

[sterile token]

Ahh right, the thing is, I'm used to the old school where there was no PDC

[echo basalt]

sounds like a you problem

[fluid river]

true

[wet breach]

technically players have always had variables

[fluid river]

i basically suggested the same thing tho

[sterile token]

Imagine 1.8 coder moving to 1.19

[fluid river]

but without external distance variable

[echo basalt]

are you trying to be ironic or something

[sterile token]

No, lmao all the clients i used to work they ask me for 1.8 plugins. Now im just rejecting them and just accepting 1.19 comissions

[brittle fjord]

Hello, I'm trying to create a "god entity" for our server. We would like to be able to type into the chat as the god entity. Is there a way to type into chat as some other alias other than yourself and is it possible to create a script where this god entity would have a conversation with some other entity in chat? Feel free to ask more questions if somethings unclear

[sterile token]

And now im having amazing zip issues with maven

[echo basalt]

only differences between 1.8 and 1.19 are:

• no magic values anymore (1.13)
• sendTitle and bossbar api
• PDC
• easy nms

[eternal oxide]

what issues?

[fluid river]

you can not force entity to chat

[sterile token]

its not being able to do descompress the dependencies

U were talking about that before

[fluid river]

you can send messages to players who pass near your entity

[cobalt thorn]

for the last line player.getLocation().distanceSquared(item.getLocaiton() < near.getLocation().distanceSquared(item.getLocation()) is giving the fact i cant use < to a location but what i should use?

[eternal oxide]

if you are including zipped files in your jar you must include them unfiltered ie.```xml
<resource>
<directory>resources</directory>
<filtering>true</filtering>
<includes>
<include>*.yml</include>
</includes>
</resource>

        <resource>
            <directory>resources</directory>
            <filtering>false</filtering>
            <includes>
                <include>*.nbt</include>
            </includes>
        </resource>```

[brittle fjord]

Is it possible to send chat messages under a different name?

[fluid river]

just use player.sendMessage("[God] Hello");

[fluid river]

i forgot one bracket

[kind hatch]

You can send messages to players that imitate the format of chat if you want to preserve your chat formatting.

[fluid river]

i changed the code

[sterile token]

but that will make, to appear [playerName] [God] Hello not just [God] Hello

[fluid river]

bro what

player.sendMessage

just send player a plugin message

[woven tide]

if I use the player PDC will it save or not?

[kind hatch]

You're thinking of Player#chat()

[fluid river]

probably

[sterile token]

idk there was a guy asking that

[fluid river]

we are using sendMessage

it can't have any playername

it's sent by plugin

[sterile token]

What could be? File data/regions.yml could not be reloaded. Reason unacceptable code point '' (0x0) special characters are not allowed in "'reader'", position 0

And the file is empty that the best part

🤦‍♂️

[fluid river]

@cobalt thorn is it working now

with changed code

[eternal oxide]

its probably not empty, just unprintable characters

[sterile token]

Hmnn

i dont think there is anything in it

[tardy delta]

pass it thro yamllint

[sterile token]

ok

[tardy delta]

its a site btw

[sterile token]

ohh lmao

i thought it was smth like jUnit

🤣

[sterile token]

Bro

But the file is empty

Doesnt have any content

🤔

how would i pass it thru there if its empty?

Doesnt make sense

[tardy delta]

idk ctrl a it and press delete or smth

[sterile token]

I mean im just loadingan empty file

Fucking spigot file system that is what i can say haha

[brittle fjord]

this one didnt seem to work

[tardy delta]

snakeyaml isnt related to spigot afaik

[sterile token]

I mean also the host where im testing, doesnt even allow me to open the file

😂

Im trying to open it via the ptedactyl file system and doesnt allow me to see the content

So smth weird in the file

[eternal oxide]

delete it and make a new file

as its empty

[sterile token]

on the source folder right?

[lilac cobalt]

I'm getting the error message "Unhandled exception executing command" and I can't figure out what's causing it. Is there something wrong with my formatting here?

  hotpotato:
    description: kill command

[tardy delta]

?paste whole stacktrace

[undone axle]

https://paste.md-5.net/

[sterile token]

That means that something is not code correctly on your command class

[lilac cobalt]

Command class? I just overrided "onCommand" and asked if the name of the command sent was equal to the name of the command I registered

[tardy delta]

paste the whole error thing so we can see

[lilac cobalt]

[12:15:45 INFO]: TheWendigo_ issued server command: /hotpotato

Did you mean everything below this? Because i'll flood the chat lol

bro what

[tardy delta]

java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics

kotlin :/

[fluid river]

you coding minecraft plguins on kotlin

[lilac cobalt]

Yee

[fluid river]

why

[lilac cobalt]

Legitimoose

[eternal night]

you'll have to shade the kotlin standard library

[fluid river]

https://www.spigotmc.org/wiki/how-to-use-kotlin-in-your-plugins/

are you sure

that you added kotlin lib

and blah blah blah

[sterile token]

oh koltlin 🤢

[lilac cobalt]

Koltin is bad?

[sterile token]

i dont really know in m ycase i just done like tht esyntax

[lilac cobalt]

Reminds me of lua, which I'm very familiar with

[sterile token]

I just like the syntax from C#, Java and TS

[sterile token]

Atleast kotlin syntax is better than Python

[tardy delta]

kotlin is a very funny language

private fun doSomething() {}```

[lilac cobalt]

I didn't do anything specific besides convert the project in IntelliJ

[sterile token]

You cant use a library which doesnt exists

[tardy delta]

you have to shade the kotlin library, meaning including it at runtime and not only at compiletime

[lilac cobalt]

I don't know what that means

[sterile token]

Oh havent u learn about java before?

Like how the lang works (atleast the basic and important things) and many other things

[lilac cobalt]

I did node js a long while ago

I'm moving from data packs to plugins now because of how annoying they are to work with lol

[sterile token]

Wait dont comapare JavaScript with Java, they are not similar but now because you know javascript means you cant code directly into Java

Its a common mistake done by lot of people

[dry forum]

if i wanted to make a bungee plugin do i need to use a database? or can i just use files like a regular plugin

[kind hatch]

If you want to share data between servers, use a database. Otherwise, you can just rely on the local databases that your plugins provide.

[dry forum]

i just need to allow commands to be used in all servers and store based on that, so that would be fine?

[sterile token]

Yes

If you want to make global commands and dont want to mess with a spigot plugin on each sever, bungee is perfect

So in your case a Bungee plugin will be the best option and you can either use flatfile or database storage

[dry forum]

ok thanks

[sterile token]

Because bungee commands can use on every sever and you dont need to sync the storage, meaning that if u do a spigot plugin u will have to sync the storage

[wet breach]

depends on the kind of data

if its data that needs to be stored, this works

but if its data that doesn't need to persist, better off just using sockets

[honest badge]

any way to check which entity launched a projectile using projectile launch event?

[wet breach]

it should have a method to see shooter?

think its getShooter() or something to that effect

[native ruin]

getentity?

event.getentity or somth

[honest badge]

that returns the projectile

[wet breach]

wel getEntity gets the projectile

[honest badge]

according to the docs

[native ruin]

getshooter?

getentity.getshoother

[wet breach]

there it is

[honest badge]

thanks

[native ruin]

is there an event of some sorts that triggers when you look at another entity?

or a way to do something like it

without having to loop through every playre every tick

[honest badge]

maybe theres something in the location data?

not 100% sure tho

[wet breach]

you could use the playermove event

and then from there trigger a timer to activate a task to loop through players that are not moving

to see where they are looking

once they start moving again, halt the task

[native ruin]

i can't use that for its purpose

[wet breach]

not sure why you couldn't

[quaint mantle]

hello, I'm creating a core for a skyblock .... I want to create an island that is not already occupied by another island, what do you recommend? use external plugins? if so, which ones?

[native ruin]

players needs to be able to move

[wet breach]

I never said to cancel the event

you can just simply use it because it is always ran

anytime they stop moving, which doesn't cause a playermove event to happen

you have a task to fill that gap

but since players are moving constantly you shouldn't have many tasks 🙂

[native ruin]

hmm like taht

yea ill go look into it

thanks

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

[eternal oxide]

passing a ThreadPool as an executor its never going to end

you are running it on every executor, which gets renewed

[bright cedar]

Hey, how could I bump a player 100 blocks in the direction he is looking ?

[wet breach]

make them hover a bit off the ground and change their velocity to 100 in the direction

and they will zoom away

[bright cedar]

Yes but I don't know how to do that

[wet breach]

fun fact if you could slow the server down, when players teleport they just run really really fast

[round finch]

java guava looks so complicated

Hey does the BlockSpreadEvent also apply to water?

[chrome beacon]

[analog folio]

no infos

[chrome beacon]

ah

then yes I believe it does

[analog folio]

Well the event get not triggered by water

[chrome beacon]

What do you need to detect water spread for?

[analog folio]

I want to limit the spread of water

Like for 4 Blocks

[rough oriole]

Hello, im having a little problem, im using spigot 1.19 and when Someone equip something in the shield slot they can not unequip it, does anyone know if this is a Vanilla bug?

[chrome beacon]

Probably a plugin

Also use #help-server

[nimble lichen]

            val packetContainer = protocolManager.createPacket(PacketType.Play.Server.ENTITY_DESTROY)
            packetContainer.integers.write(0, 1)//size of entities array
            packetContainer.integerArrays.write(0, intArrayOf(event.entity.entityId))

I get "Field index 0 is out of bounds for length 0" on both write lines. What am I doing wrong? (ProtocolLib)

It's Kotlin but everything works the same

[chrome beacon]

Are you sure that's the correct packet format?

[nimble lichen]

https://wiki.vg/Protocol#Remove_Entities

I've tried not setting the count value

both lines make it seem like I shouldn't write to those places

[chrome beacon]

Is there a reason why you can't use the api

[nimble lichen]

which api

[chrome beacon]

Spigot

[nimble lichen]

version compatibillity

You mean nms?

[chrome beacon]

No

[nimble lichen]

how would I hide an entity from a player using spigot api

[chrome beacon]

?jd-s

[undone axle]

I've already looked and I personally couldn't find anything. Perhaps something new that I dont know of like attributes ?

o

its in the player class

thx!

[chrome beacon]

It's quite new

So you might still have to use packets for older versions

[nimble lichen]

no this is perfect

How could i make a larger array from 2 smaller arrays, for example like this:
ItemStack[] updatedItems = { oldItems, newItems }; but ofc that doesnt work, how else would i do it

[fresh timber]

I am trying to turn a player's gamemode to adventure when they join and I have some very strange problems. I have this code and it uses player.setGameMode(GameMode.ADVENTURE). This only works when the player is in a rank (on my luckperms permissions plugin) that has the permission *. If they are OP it also does not work. I have some Sysouts to test and right after I set their gamemode, I print their gamemode and it says their gamemode is ADVENTURE although when they join the server, they are in survival. If the player is in a rank with perm*, however; it does set their gamemode to adventure. The gamemode in server.properties is adventure and force-gamemode is set to true. If anyone could help me with this that would be amazing, I just can't seem to figure it out.

@EventHandler
public void onJoin(PlayerJoinEvent event) {
    System.out.println("1");
    Player player = event.getPlayer();
    System.out.println("2");
    UUID pUUID = event.getPlayer().getUniqueId();
    System.out.println("3");
    final Location location = new Location(Bukkit.getWorld("hub"), -0.5, 65, -0.5);
    System.out.println("4");
    player.teleport(location);
    System.out.println("5");
    player.setGameMode(GameMode.ADVENTURE);
    System.out.println(player.getGameMode());
    if (player.hasPermission("wildgames.fly")) {
        player.setAllowFlight(true);
        player.setFlying(true);
    }
    System.out.println("7");
    BuildModeMap.remove(pUUID);
    System.out.println("8");
    player.getInventory().clear();
    System.out.println("9");
    ItemStack item1 = new ItemStack(getItem(new ItemStack(Material.ENDER_EYE), "§a§lGame Selector", "§7Click to open the Game Selector (/gameselector)"));
    System.out.println("10");
    Inventory inv = player.getInventory();
    System.out.println("11");
    inv.setItem(4, item1);
    System.out.println(player.getGameMode());
    player.getInventory().setHeldItemSlot(4);
}

[drowsy helm]

Use a runnable and delay it a tick

[fresh timber]

hm

do I do that in the onEnable or in the class?

like when I register the listener

[drowsy helm]

In the event handler

[fresh timber]

ok

[drowsy helm]

Just since it’s player join it might be iffy

[fresh timber]

yea

wait what do I put for the second input of .runTaskLater

[grave plover]

First the javaplugin, then runnable, then delay in ticks

[fresh timber]

hm ok

[quaint mantle]

would there be a better way of doing this

public void enchant(Location loc1, Location loc2) {

        double minX = Math.min(loc1.getX(), loc2.getX());
        double minY = Math.min(loc1.getY(), loc2.getY());
        double minZ = Math.min(loc1.getZ(), loc2.getZ());
        double maxX = Math.max(loc1.getX(), loc2.getX());
        double maxY = Math.max(loc1.getY(), loc2.getY());
        double maxZ = Math.max(loc1.getZ(), loc2.getZ());

        for (int x = (int) minX; x <= maxX; x++) {
            for (int y = (int) minY; y <= maxY; y++) {
                for (int z = (int) minZ; z <= maxZ; z++) {
                    if (!mats.contains(loc1.getWorld().getBlockAt(x, y, z).getType())) continue;
                    setBlock(x, y, z, Material.AIR, loc1.getWorld());
                }
            }
        }
    }```

optimization wise

[errant snow]

Can anyone think of a reason why some methods would only get the initial value of a variable (upon class instantiation), but other methods can change it and get the new correct value without issue

I'm going crazy over this

[thorny marsh]

sorry was too stupid to read around, i already found out sorry for the disturbance but thanks!

[fluid river]

what?

[raw prairie]

@eternal oxide

Dammit

[fluid river]

i guess weird design patterns are the reason

[errant snow]

page is the problem child, in the increment method i'm just adding 1 to it, both messages print the correct value of page

private var page = 1

fun increment() {
    Chat.broadcast("&cIncrement page before: $page")
    page += 1
    if (page > pages.size - 1) page -= 1
    Chat.broadcast("&cIncrement page after: $page")
}

This is the problematic method render, it also uses the exact same page variable, it's in the same class and everything, but no matter what the page variable is set to it only reads the initial value of 1, all of the print messages also show 1

override fun render(inventory: Inventory) {
    if (preCheck()) return

    Chat.broadcast("Pages size: ${pages.size}, Rendering page $page")
    pages[page].render(inventory)
    Chat.broadcast("Rendered page $page")
}

Some sample output

The expected output would be the white messages show the latest value of page, the value printed in "Increment page after: <num>"

I can't for the life of me wrap my head around it, I tried changing the initial value of page to 0 and the render method uses 0 instead, but it never gets the accurate value of page

[fluid river]

you mean you are rendering page 1

but should render page 12

on the screenshot

your increment and render have no connection tho

paste the whole class

[fresh timber]

aah I delayed it 5 ticks and it worked. Thanks for the help! I was really stuck on this one

[errant snow]

https://hastebin.com/gurefaxani.kotlin

the increment and render methods are called outside of the class, but they both access the same variable, or at least they should

I checked the compiled java code just to be sure there isn't a weird issue there, but there aren't any discrepancies that I noticed

[quaint mantle]

Anyone?

[echo basalt]

I mean

there are some ways you can optimize it

but it's really specific and depends on how big the volume is

[quaint mantle]

I mean, it'll vary. Around 25x25 area every 10 blocks broken ish

• like 30 players

So around 18k loops every 2 seconds

Which i dont like

[echo basalt]

You could... make a weird queue and process chunk snapshots async instead

[quaint mantle]

My set blocn function is rock solid but the looping on the other hand, i could make a different thread, but again. Thats like 18k threads which isn't good either

[echo basalt]

thread pool

[quaint mantle]

True..

[quaint mantle]

And how would i do this 😅

[echo basalt]

Let's start with a queue / deque of the locations to be broken

Which should be concurrent so we can add in 1 thread and loop in another at the same time

You can use synchronized blocks or just look for a concurrent queue implementation

Deque<Location> breakableLocations = new ConcurrentLinkedDeque<>();

[quaint mantle]

Okay..

[echo basalt]

and either break like 50k blocks per second (random number) or limit it to a ms/t variant

[quaint mantle]

Sorry looking up deque because i actually haven't used it before

So would i loop the deque?

[echo basalt]

Variant A:

private static final int BLOCKS_PER_TICK = 50000;

public void processQueue() {
  int iterations = 0;
  
  while(iterations < BLOCKS_PER_TICK && !breakableLocations.isEmpty()) {
    Location location = breakableLocations.pollFirst();
    ...
  }
}

Variant B:

private static final double MAX_MILLIS_PER_TICK = 15;
private static final int MAX_NANOS_PER_TICK = (int) (MAX_MILLIS_PER_TICK * 100000);

public void processQueue() {
  long endTime = System.nanoTime() + MAX_NANOS_PER_TICK;

  Location next = null;
  while(System.nanoTime() <= endTime && (next = breakableLocations.poll()) != null) {
    next...
  }
}

run processQueue sync on each tick

[quaint mantle]

Okay i see, where would i put this or do i need to implement anything?

[echo basalt]

So now we have the structure to:

• Add elements concurrently to a list, that-
• Get processed sync, on the next thread, without ever having TPS drops

[quaint mantle]

I can see me using this alot

[echo basalt]

And now we need to:

• Create a snapshot, process it on the thread pool, and populate the deque

This is just a dumbed down version of

[quaint mantle]

Lol

how can i schedule something to run in x seconds using bungeecord? ive only found how to do it every x seconds

[pearl glade]

why don't you update the chunk?, it will be much faster than updating block by block

[radiant umbra]

Hello, does anyone know how i can convert a skull value to a skull url?

[echo basalt]

pretty sure

the stull value is just a base64 serialized json tag that contains the url

[quaint mantle]

Okay, i understand the deque part and splitting the workload, but how would i implement this so i can use it in my own?

Like what do i add to my code already to make the deque and all that work

I probably missed something in the tutorial

Oh, i kinda see how he did it in the github

[worldly ingot]

There was no particle API in 1.8

So... no.

In 1.9 (and even present day) you can spawn particles via Player or World, the latter being for any nearby players

[quaint mantle]

Packets? 🤷‍♂️

[worldly ingot]

Yes

[quaint mantle]

Yep

[worldly ingot]

There was a popular library back in the day. Forget who it was that made it

Darkbladde13, that's the guy

https://github.com/DarkBlade12/ParticleEffect

You basically just copy/paste those two classes into your project and use that as the API. Though really, you should just be updating to a version that isn't 7 years old

[quaint mantle]

Easy fix, dont use 1.8 🤯

how do I set a custom block in the world

how do I set in the world now

[fluid river]

?

you just take a world, take a location

and set the type to what you need

and then apply blockdata

if that's for plugin tho

[golden turret]

you missed the custom block part

[fluid river]

what makes your block custom tho

it has NMS part?

or just block data

[golden turret]

nms

[fluid river]

i guess you need CraftWorld or what is it rn

NMSWorld

and BlockPosition

and then IBlockData

[golden turret]

ik

i want to know how to create the blockdata

[hasty prawn]

You can't set custom blocks like that

Or, you can't make them like that at all.

The client would have absolutely no idea what you're doing

[fluid river]

NMS World should have methods for setting blocks

[golden turret]

I am simply editing an existing block

[fluid river]

with light update and info sending

[hasty prawn]

I mean maybe? No idea how the client would respond honestly. You for sure can't change the texture of it.

Not like that anyways you can't

[fluid river]

iirc CraftWorld#setBlockAndData does send the data to players somehow

performs light update and stuff

but idk what is used in 1.19

[stuck flax]

Does Material.WHEAT represent both the block and item?

[fluid river]

this is for older version

[atomic swift]

EntityDeathEvent including players?

[fluid river]

yes

[fluid river]

yes

it even has blockdata ageable

[stuck flax]

aight, ty

[atomic swift]

is there a mob deathevent

[fluid river]

you have PlayerDeathEvent

[atomic swift]

ik

[fluid river]

no need for entity i guess

[atomic swift]

i need entity

[fluid river]

alr

[atomic swift]

but i also want player

[atomic swift]

.

will this work if (event.getEntity() instanceof Player) {

[remote swallow]

Should do

[atomic swift]

also does EntityDeathEvent get what the entity died by?

bc it doesnt look like it

[glad prawn]

Reason?

[atomic swift]

so if a mob dies

[remote swallow]

Whats a mob, its an entity

[dense fjord]

Ok so i started learning java and i tried making a simple fly plugins

But

package org.bukkit.command;

import org.jetbrains.annotations.NotNull;

/**
 * Represents a class which contains a single method for executing commands
 */
public interface CommandExecutor {

    /**
     * Executes the given command, returning its success.
     * <br>
     * If false is returned, then the "usage" plugin.yml entry for this command
     * (if defined) will be sent to the player.
     *
     * @param sender Source of the command
     * @param command Command which was executed
     * @param label Alias of the command which was used
     * @param args Passed command arguments
     * @return true if a valid command, otherwise false
     */
    public boolean onCommand(@NotNull CommandSender sender, @NotNull Command command, @NotNull String label, @NotNull String[] args);
}

Yes

i cant edit it

and

It sasy cant resolve symbol NotNull and jetbrains

what do?

[fluid river]

bruh

dm me

you don't need to use commandExecutor itself

and @NotNull annotation from jetbrains should be in your IDE already

shit

[tall dragon]

yea that guy is popular

😮

[fluid river]

tagging him for 10th time already

[tall dragon]

imagine naming yourself @fresh templetHandler tho

woops

sorry ahaha

why the frik it even do that

[opal juniper]

it’s not

[fluid river]

it is, just used wrong word

[opal juniper]

i’m pretty certain that they aren’t in the jdk

[fluid river]

yeah i meant IDE

just shot my leg when said JDK

[frail gale]

Hey guys

does someone know if there’s a way I can view all my Java Compiled Classes size? If there’s a program to view your classes size?

[fluid river]

why don't you just look inside the jar

[frail gale]

Yeah this is a way too

[fluid river]

to see size of each .class file

or if you don't have winrar

go to the folder with your .java file

[frail gale]

imagine you don’t have WinRaR in Windows it has a Infinity Free Trial

[fluid river]

and run javac YourClass.java in powershell in that folder

it will compile your code and generate .class file for you

[frail gale]

yeah that’s good thanks but also is there a way to see each line of your code how much size it takes?

[fluid river]

it's useless

java compiler turns it to another line anyways

[tall dragon]

yeaa its turned into bytecode

[fluid river]

i mean

[frail gale]

that’s for sure yea

[tall dragon]

you could do a heapdump on your program to view object size though

thats usefull

[fluid river]

java compiler simplifies your for(string s : list)

to for(int i = 0; i < list.size(); i++)

[frail gale]

how?

[tall dragon]

well ur making a spigot plugin right?

you could download the plugin spark

to generate a dump for you

[frail gale]

Didn’t know that thanks 😊

[fluid river]

object size in your VRAM i guess

not as actual file

[tall dragon]

yes indeed

[fluid river]

idk if he wants that

[tall dragon]

but as actual file is not really relevant

[fluid river]

is there even a reason to check your class file size

[tall dragon]

i cant think of one. but eh

[fluid river]

like it's gonna be something around 1kilo or 50kilo

no other options

or it's super small

or it's super giant

[tall dragon]

cough Material class

cough

[fluid river]

yeah we are all rewriting Material class

here on spigotmc

[frail gale]

My Plugin’s size for right now is 150KBs

[fluid river]

my average plugin is around 40

[frail gale]

and I want to find a way to reduce it if I can

[fluid river]

i guess you just have spaghetti

boilerplate

[tall dragon]

pretty sure maven has some kind of minimize feature

[fluid river]

a lot of repeating code

[tall dragon]

could look that up

[fluid river]

maybe he shaded entire spigot api into plugin hehe

[frail gale]

I mean it will be really big plugin

Maybe the size is bigger because it has a lot of Utils classes

[fluid river]

who knows lol

we didn't see it

use winrar

or well

[frail gale]

yeah I’ll do that

[fluid river]

you can write a program

in java

give it a folder

it will loop through all files in the folder

and sysoutprintln their size

🙂

[frail gale]

that’s also good idea

[fluid river]

i bet half of spigotmc don't know how to write main method in java

[tall dragon]

u legit just have to type "main" and click enter

[fluid river]

trueeee

same as i always use sysout and eclipse autocompletes it to println for me

[tall dragon]

for entellij enjoyers ofcourse

[frail gale]

Make sure you don’t include non-dev members of Spigot

[fluid river]

eclipse has the same feature

[tall dragon]

i have no idea bout that

i got eclipse once

threw it away after 1 hour

[fluid river]

for intellij it's sout i guess

[frail gale]

Mate I have two OS and one time I wrote in IntelliJ Idea in the system that I don’t really write and I really liked it

[fluid river]

i threw intellij

it's too much for me

[tall dragon]

eh its perfect for me

[fluid river]

i guess i'm average asceticism enjoyer

eclipse is like super lightweight

install archive unpack to folder run and forget

[tall dragon]

i do agree that testing standalone programs on eclipse is way faster

idk how tbh

they dont recompile or something

[fluid river]

well afair IntellIJ has option to download JDK for you

or is it VS Code

[fierce whale]

Is there any way to get name of inventory in InventoryCloseEvent
I can't find that method 😦

Please help me..

[fluid river]

inventory.getView().getName()

i guess

[vocal cloud]

Intellij may use 8GB of memory at all times but it's got a lot of fun stuff under the hood that makes it worth it

[frail gale]

Generally it’s a lot more customizable than Eclipse

[fluid river]

see no real customization there

which is not in eclipse

[fluid river]

for example?

[vocal cloud]

Better refactoring,easy integrated JDKs, integrated database support with automatic SQL query detection in strings. I could go on forever. I used to use eclipse and thought I hated java. Turns out I just hated eclipse.

[fluid river]

Better refactoring stands to?

Eclipse also provieds integrated jdks

but i still prefer downloading manually

database support is part of JDBC

not IDE

[vocal cloud]

Not sure if eclipse can but intellij can search comments and strings when refactoring. That with the ability to refactor a variable across the entire project is really nice.

Database support means I don't need a separate application to do anything related to the database. I can create,update,view,delete tables in-house without the need for a program or tests. I can run queries and everything else as well

[frail gale]

One thing I really hate in Eclipse is for example if you want to have IntelliJ Auto-Completion there’s no good way to have it

[fluid river]

umm

you mean hosting the DB

[frail gale]

For example in Eclipse you add all the keybinds to AutoCompletion and after that when you type it’s good right yeah but when declaring a new variable and adding “;” at the end it changes the name to the suggested one which is very annoying

[vocal cloud]

No

[fluid river]

what?

[vocal cloud]

I mean I have complete control over a db

I don't need 3rd party software to do anything

[fluid river]

eclipse have autocompletion

highly configurable

same as intellij

[tall dragon]

Bassically phpmyadmin build into intellij i guess?

[frail gale]

IntelliJ AutoCompletion is opening when you’re typing directly

[fluid river]

oh you mean that

[frail gale]

no need to Ctrl Space or hit “.”

[fluid river]

i hate it tho

as i said

[vocal cloud]

Yeah, sorta

[frail gale]

When I used IntelliJ Idea I really liked it

[fluid river]

average ascetism enjoyer

same as when i coded for c and c++

[vocal cloud]

Works on every modern db though

[fluid river]

well i host db manually

[frail gale]

I tried to implement it in Eclipse but it wasn’t perfect and I removed it

[fluid river]

Postgre ❤️

[vocal cloud]

Dude it's not about hosting

[frail gale]

both IDEs are good I will say

[vocal cloud]

It's about control

[fluid river]

wdym control

you just do a statement

CREATE TABLE IF NOT EXIST

done

[frail gale]

I like them both and I will try to use them both

[vocal cloud]

You can store all of it in intellij rather than needing external software

[fluid river]

all of what

the only external software i have is PostgreSQL

[vocal cloud]

SQL, ideas, etc.

[fluid river]

For like creating dbs for me

[vocal cloud]

It's all within the ide

Intellij is superior in features

Doesn't make eclipse bad

[fluid river]

well yeah IntellIJ has more features

but from what i can see some features are just implementations of external things

if i would develop an ide i would only add maven/gradle and git support

dark theme and auto-complete on hotkey

nothing else

[vocal cloud]

Well yeah, but productivity-wise that's never going to fly

[fluid river]

i mean these are the only things i use in eclipse

and i don't really need anything else

git support just highlights classes with blue to show that they are changed but changes are not commited yet

maven support is like default

dark theme is necessary

[vocal cloud]

Sure, you don't need it but it'd be nice to have

[fluid river]

well i'm not fan of integrated external things

[vocal cloud]

You're the odd one out

[fluid river]

guess just my experience wants me to learn software

which would probably be on the job

so now i know Postgre

Some git commands

some linux commands

[fluid river]

tho switched to github desktop cuz easy

[vocal cloud]

Intellij as pretty much all the features of desktop built in as well lmfao

You don't need to switch applications to handle that

[fluid river]

and well eclipse still eats memory but at least i'm able to run server + minecraft + IDE + browser on my laptop

with intellij it just dies 🙂

[vocal cloud]

Yeah, but that's cause your dev environment is on the low end.

[fluid river]

some of the features of intellij are just in running state even if i don't use them

[vocal cloud]

Causal 6GB

[fluid river]

my laptop has 8

well my pc has 16 but i have eclipse there too

[vocal cloud]

I'm using it for rust rn with the linter on constantly so it eats ram

[fluid river]

linter?

[vocal cloud]

Lint, or a linter, is a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs. The term originates from a Unix utility that examined C language source code.

[fluid river]

umm

i guess every ide flags errors?

[vocal cloud]

Yeah, but with Rust I use an external linter

and that uses more memory

[fluid river]

🙂

[fluid river]

the best option i found in eclipse

is own code formats

by default if you have one-line if action it still goes to the next line

if (a)
    b();```

but i changed it to java if (a) b();

[vocal cloud]

That's different lol but okay

[fluid river]

wdym?

that's exactly the same

[vocal cloud]

You're talking formatter I'm talking linter

[fluid river]

i said

not connected to linter

when i typed linter in browser it gave me russian database ЛИНТЕР(LINTER) hehe

[vocal cloud]

Yeah, but that's a universal thing. Every basic tool has that

[fluid river]

yeah, but the simplicity of it is just 🔥

[vocal cloud]

Yeah, works the exact same on Intellij

[fluid river]

like through VS code, VS, IntellIJ, Eclipse i find eclipse most lightweight in size, small in RAM and fast in executing what i need

small features list just makes it easier to find option you need

[vocal cloud]

Yeah, as I said before. Eclipse is fine it just lacks a lot of features that I use in intellij

[fluid river]

and execution is hella fast

tho there is one thing which i don't understand in intellij

[vocal cloud]

I mean higher learning curve intellij means that eventually you'll know enough that small feature list becomes irrelevant

[fluid river]

why can you only work with one project in one tab

i dislike it

[vocal cloud]

You can have multiple

[fluid river]

when you open a project there is a window

Open new tab

or open project in existing tab

which is iirc closing your current project

and switching to one you selected

like that's so nice that when i'm creating a new plugin i can just open one random plugin i coded before

and copypaste pom.xml contents

i guess main reason why i'm in eclipse

is that i prefer copypasting over coding

[vocal cloud]

Well if you spend most of your time copypasting lmfao

you can open multiple in intellij too I just don't cause that's messy

[jagged monolith]

The only real multi-project support Intellij has is if you're adding other projects as modules to one over-arching project.

[vocal cloud]

Yeah, but imo it's fine because each project should be it's own window

[jagged monolith]

Otherwise, you'll need to use different windows.

[fluid river]

which basically means two instances of ide

[jagged monolith]

Agreed, I usually prefer each project having it's own window. Makes things simpler and easier to determine what's what.

[fluid river]

well, you have a Close project button here

[vocal cloud]

Unless you're a coder who uses a lot of bad practice it shouldn't be that big of an issue

[fluid river]

so it closes all of the project's tabs

and doesn't check it's errors/warnings

[jagged monolith]

Each to their own really. Intellij and Eclipse both have their good and bad. It really comes down to use case and personal preference.

[fluid river]

i guess it comes more to pc specs

[frail gale]

@fluid river Do you know a good Decompiler plugin for Eclipse?

[fluid river]

?

i guess good is not to use decompiler

[frail gale]

Decompiler plugin for Java classes

[dense fjord]

Ig im rdy now

[frail gale]

I want to decompile some NMS

[fluid river]

tho you can just open the class from api

if included

[vocal cloud]

Intellij has fernflower

[fluid river]

idk never used decompilers

except JD-GUI

once in my life

[frail gale]

I mean it’s telling me source not found

[fluid river]

maybe eclipse has it

maybe not

[jagged monolith]

Why not just use something like https://marketplace.eclipse.org/content/enhanced-class-decompiler (Just google Eclipse decompiler, not hard to find one 😛 )

[frail gale]

Did the same mate I google it but still I asked if there is better

[worn tundra]

What about JD-GUI

[frail gale]

I have it

[fluid river]

what about not decompiling

[frail gale]

I also have Luyten

but I asked for integrated

[frail gale]

Sometimes I think you need

[fluid river]

tho you can just use sources downloaded with buildtools

[vocal cloud]

[fluid river]

they are all .java iirc

[frail gale]

He is proving everything that Eclipse is missing

[vocal cloud]

Built into intellij

[fluid river]

eclipse has same two buttons tho

[vocal cloud]

Including fernflower

[fluid river]

update project

[frail gale]

Can I customize the IntelliJ UI?

[jagged monolith]

Of course

[vocal cloud]

Depends what you mean by customize but yeah

[frail gale]

I wanna rearrange the buttons

[bright cedar]

Hey, I still don't understand how I can bump a player a 100 blocs forward, can anyone help me please ?

[jagged monolith]

Just update the players location

[frail gale]

you mean teleport them 100 blocks forward?

[fluid river]

ez

[bright cedar]

No, like with a jumppad

[frail gale]

I think you’re gonna need to use velocities

[jagged monolith]

You'd need to play with velocity and have a check for location etc..

[frail gale]

Velocities are cool

I think

[jagged monolith]

Haven't mess with them personally haha

[frail gale]

same

[bright cedar]

Yes but I don't know how 😕 I tried to play with velocities but I always push me in diagonal

[frail gale]

You can google some tutorial for Velocities

also I can send you a video about a JumpPad Plugin

[bright cedar]

Yes I'd like to please

[frail gale]

the channel is called SyntaxError

you can see his videos

he has tutorials for plugins with unique ideas

[bright cedar]

Okay thx

[frail gale]

also please don’t skip and copy-paste instead watch the entire video just a tip don’t take is as offending

[vocal cloud]

99% of code tutorials should be text. Can't change my mind

[warm mica]

Most often there are either no docs at all or the docs are so bad that the dev could have just not made any in the first place

[fluid river]

yeah that's why i run text java blog

in russian

sometimes i link pictures of what's happening

but that's console app so not really necessary

[brisk estuary]

i know it's not related to spigot development, but could someone help with c? pm

[mighty pier]

knitter

[thorny marsh]

Do someone know if the blockspreadevent count for water?

[fluid river]

water is BlockFromToEvent

[thorny marsh]

Well i limit the water for x Blocks with the BlockFromToEvent but if the water flow to the ground its spread and the limit dont work for All sides thats why i thought maybe BlockSpreadEvent would help

[normal loom]

Hello guys, is there a way to check if an event is running?
For example let's say you ran a command like "/givespeedtoeveryone" with a speed duration of 5mins, so all online players receive speed, but if a player joins the server after the command is executed does not receive it, how can i check if the event givespeedtoeveryone is still active and give the speed to the player who has logged in?

[eternal oxide]

https://www.spigotmc.org/wiki/feature-command-cooldowns/

[echo basalt]

that's more of a OOP question

[vocal cloud]

Make a cache that contains active effects and their end time stored as a long. When a player joins do the math to determine how long it has left based on that.

[echo basalt]

And data structures

[normal loom]

so when a player joins, i check if he is stored, if not i give to him the effect?

[vocal cloud]

When a player joins you check if they've received this exact buff by using a unique id per command usage. If they have not you apply either the full effector if you want it to be based on duration left, you give them the amount left based on a stored expiry time.

[normal loom]

Alright, understood ❤️

[tender shard]

wtf is that

[eternal oxide]

a search result 🙂

[tender shard]

using a timer for every cooldown?!

that must be a joke lol

[eternal oxide]

I didn;t read it, just searched

[echo basalt]

Would it be possible to make a plugin that uses Unsafe to inject into worldmanager and just make worlds fully thread safe

🤔

[eternal oxide]

The timestamp method looks fine

[echo basalt]

then minecraft updates and it breaks everything

[tender shard]

that's why I called the post a joke

yeah a runnable only makes sense to show a timer or sth

[fierce whale]

is there any fancy way to serialize custom java Object which contains Bukkit Object?

[crimson terrace]

uhhh what do you wanna serialize it to? Json? a yml entry? csv?

[eternal oxide]

and what Bukkit Object?

[crimson terrace]

that too

[fierce whale]

I tried save it into .yml by String

[fierce whale]

It's ArrayLIst of Itemstack

[crimson terrace]

use ConfigurationSerializable

[eternal oxide]

ItemStacks are already serializable

[crimson terrace]

since ItemStack is already that

[fierce whale]

umm..

[crimson terrace]

google

[tender shard]

just do myYaml.set("mylist",myList); lol

[fierce whale]

Is there any tutorial for ConfigurationSerializable?

[tender shard]

the javadocs explain everything you need to know

I tried to find information about that but It was so hard 😦

Okay Thanks I'll tried that

[crimson terrace]

ima send you an example of a ConfigurationSerializable class hold on

[fierce whale]

Oh thanks! 🙂

[crimson terrace]

got like 50 here

[fierce whale]

Wow...

[crimson terrace]

its really useful

?paste

[undone axle]

https://paste.md-5.net/

[crimson terrace]

I use this class for serializing and deserializing boss bar information to and from config https://paste.md-5.net/hulonigibu.java

it implements ConfigurationSerializable at its core

[fierce whale]

Okay really thank you! 👍

[crimson terrace]

the main things are the deserialize and serialize methods, aswell as the @SerializableAs("") at the top

[fierce whale]

Okay I gonna check it right now with document you sent 🙂

[tender shard]

public class Person implements ConfigurationSerializable {
    
    private final String name;
    private int age;

    public Person(String name, int age) {
        this.name = name;
        this.age = age;
    }

    @Override
    public Map<String, Object> serialize() {
        Map<String,Object> map = new HashMap<>();
        map.put("name", name);
        map.put("age", age);
        return map;
    }
    
    public static Person deserialize(Map<String,Object> map) {
        String name = (String) map.get("name");
        int age = (int) map.get("age");
        return new Person(name, age);
    }
}

[crimson terrace]

I usually use static final strings for the keys of each attribute, makes it easier to edit

[fierce whale]

Oh I got it thanks for your help!

[native ruin]

does the nether have time ticks like the overworld?

[crimson terrace]

the whole server does

thats what times the spreading of lava and water for example

[native ruin]

ok ty

oh no i meant day night cycle time

but yea

the nether doesn't

[quaint mantle]

No

It dont

[fierce whale]

I saved custom java object which implements ConfigureSerializable.
But I don't know how to load that object again

I tried to use config.get(path) method but it doesn't work 😢

how to get object from configuration file?

[eternal oxide]

did you register the class?

[crimson terrace]

you can use the deserialize method for that.

[crimson terrace]

You need to register it to ConfigurationSerialization

best time for that imo is onLoad()

[fierce whale]

yes I registered it
But when I use config.get(path). it invoke deserialize method automagically?

[crimson terrace]

basically. you can do "CustomObject customObject = (CustomObject) config.get(path)"

[dreamy dove]

omg I did not know this hahah thanks man! I googled but not found something like this

[fierce whale]

hmm.. I used that method...

[crimson terrace]

well, did you register the serializable class?

[fierce whale]

yeah I will show you my code

[crimson terrace]

are there any errors in console?

[fierce whale]

public class sertest implements ConfigurationSerializable {
    {
        ConfigurationSerialization.registerClass(sertest.class);
    }

ummm... just a moment plz

[eternal oxide]

that won;t work.

[fierce whale]

org.yaml.snakeyaml.error.YAMLException: Could not deserialize object

[crimson terrace]

thats my thought too, should be tthat exact error

[eternal oxide]

it only registers it when you instance the class. You need to register it before accessing the config

[crimson terrace]

use the onLoad() method in your main class

override it

[fierce whale]

in main method?

onEnable?

[crimson terrace]

main class extends JavaPlugin right?

[eternal oxide]

plugins have no main method

[fierce whale]

yeah

[crimson terrace]

just make a new method onLoad()

and put that code there

[fierce whale]

like registering event?

[crimson terrace]

what?

you put a new method in the main class

@Override
public void onLoad(){
}

[fierce whale]

Aha

Oh I got it!

[crimson terrace]

and register the ConfigurationSerializable class there

[fierce whale]

Okay Let me try

[crimson terrace]

that method is used before the onEnable() method so you can prepare stuff like that

[fierce whale]

    @Override
    public void onLoad() {
        ConfigurationSerialization.registerClass(sertest.class);
    }

Is it right?

[crimson terrace]

yeah

that should fix your earlier error

[fierce whale]

Thanks 😀

OOHHHHH It works...!
thank you so much! 🙂

[crimson terrace]

🙂

dont forget the SerializableAs annotation so you get rid of the path for a class name

paths are ugly in config

[fierce whale]

Okay I got it!

[quaint mantle]

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

        NamespacedKey key = new NamespacedKey(Housing.inst, "playerData." + p.getUniqueId() + ".testNum");
        p.getPersistentDataContainer().set(key, PersistentDataType.DOUBLE, 0.0);

        return false;
    }
``` Would this be the correct way to set data for a player?

And if I restart the server would it keep this data?

I just wanted to make sure it works

and I just realised

I won't ened the getuniqueid

because its p.getPersistentDataContainer()

belongs to that player

I set up this

but it's not outputting to that directory

[tender shard]

you must specify an execution

[quaint mantle]

it works in my other plguins like that

[tender shard]

btw you you should never use the shade plugin to change the output directory

https://blog.jeff-media.com/common-maven-questions/

[quaint mantle]

shade?

[tender shard]

you sent a screenshot of the maven-shade-plugin without any executions

it will not do anything

what are you trying to achieve?

[quaint mantle]

i just realised in my old plugins it uses maven-jar-plugin

not shade

i didnt set it to shade that was the default

[tender shard]

shade and jar are two totally different plugins

anyway, yeah, the maven-jar-plugin is the correct one to change the output dir

[quaint mantle]

I just use this thing

idk why it used shade

:/

well it works now

so im happy

[fierce whale]

which one is better way to save data?
using internal variable like HashMap and saving it into yml file in every 5 minutes (every fixed period)
or
every time access to yml file and change some of data.

[eternal oxide]

So long as saving is async it makes no difference

[fierce whale]

so... it's same speed?

[eternal oxide]

File access is slow, so do it async

[fierce whale]

hmm.. how can i use async?

[eternal oxide]

Scheduler or Futures

[fierce whale]

aha I got it

thank you!

[vivid cave]

hello

I remember that in snapshot 20w14infinity nether portal frames could have different colours

Is it possible in 1.19? (no datapack, no texture pack)

Like is it possible (from plugin) to place down a nether portal block in specific colour?

Or does it necessarily need a texture/data pack?

Cuz 20w14infinity didn't store all the portal blocks as texture i guess but just generated a random colour

[hasty prawn]

It probably did that client side though

So I doubt there's a way for the server to tell the client what color to render it as.

[vivid cave]

alrightie

thx

[hasty prawn]

You'd have to do some NMS digging to really see how they did it and then check if they left code (which I doubt) in 1.19

[vivid cave]

oki

[dreamy dove]

yeah but my problem is now that the default server packets that get send to the player overrides my sended block damage progress

[fresh timber]

in a bungeecord plugin ServerConnectedEvent event, how can I get the size of the players on the server that the event occurred on

[golden turret]

how to create custom block using the NMS?

[naive bolt]

how do i get sound from block data

[worn tundra]

What do you mean and why do you want to use NMS for them?

[river oracle]

Probably easier that way with world gen and all

[worn tundra]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/data/BlockData.html#getSoundGroup()

[worn tundra]

Ah perhaps

[golden turret]

create custom block

[vocal cloud]

It won't persist so doing so can be pointless

Depends on what you want it for

[worn tundra]

There are some open source projects down below, check out how they do it
https://septicuss.notion.site/Blocks-d2cdd4b22d9f495193d5759030ed749c

But if you're going for the world gen, you should just simply set the blockdata while generating the world

[vocal cloud]

What version of MC is that for? Modern versions have access to custom model data

[worn tundra]

Custom model data is for items

[vocal cloud]

And blocks

[worn tundra]

Nope

[vocal cloud]

Yup

[worn tundra]

Otherwise all those complicated plugins wouldn't exist

Mind showing where I can set a placed blocks custom model data?

[hasty prawn]

Yeah custom model data only exists for items not blocks

[worn tundra]

^

[hasty prawn]

Generally you have to use like block states for custom blocks

[tender shard]

"custom blocks" are usually done through mushroom blocks or noteblocks with "not avilable in vanilla" blockstates

[worn tundra]

As explained here

[vocal cloud]

I thought they did something. Huh I'll have to look through my bookmarks

[hasty prawn]

Hey man I want you to be right LMAO

[worn tundra]

Trueee

[hasty prawn]

I wish they had custom model data for blocks

[worn tundra]

Haha

[vocal cloud]

Oh it's the item frame method. I guess I didn't look too much into it. My bad

[frail gale]

same

actually you can add Custom Model Data to blocks with modding

[worn tundra]

Well modding just goes over the point of it doesn't it

[frail gale]

what is better?

[vocal cloud]

If you're like me and making a modded server mods are better than the item frame method

[frail gale]

Having multiple Runnable Anonymous Inner Classes or making a outer class which extends Runnable and then doing it from the class

[vocal cloud]

Depends if you're reusing the code a lot. If you are then making a class is superior

[frail gale]

At some point I use it a lot

[worn tundra]

Get a larger audience if they don't have to download external required mods by themselves / through a launcher. Resource packs are just a < 2mb download on join and you already get so much content.

[eternal oxide]

pass it a single executor not teh whole pool

[vocal cloud]

Wym get a larger audience lol. Some of the interest is from it being modded

[worn tundra]

Means that a user can join / find out your server by just pasting the IP in and voila

For mods peeps have to download extra stuff which raises the bar for potentially joining

Can't argue with this tbh

[vocal cloud]

Ah that's not an issue per-se. The lobby is vanilla and explains everything

They can decide from there

[worn tundra]

Well that's more like a workaround

[vocal cloud]

I mean mods allow a unique experience you can't experience in vanilla

[shadow gate]

Can you tell me what type of click event to use, that when clicked, a new message was sent from the plugin to the player?

[vocal cloud]

I don't understand your message? What's being clicked

[hoary wing]

how can i put an actionbar in a game ?

[worn tundra]

Like what? I can be certain that nearly any mod mentioned could be recreated to some extent in vanilla

[shadow gate]

Example

[vocal cloud]

Custom player animations. Tonnes of custom blocks with custom break sounds. Custom GUIs with easy scrollable UIs

[worn tundra]

It's a clicked message that sends a command in chat

[shadow gate]

Yeah, thanks

[worn tundra]

Custom player animations.
https://www.youtube.com/watch?v=_4-pdYOqfPg
And ItemsAdder for ex adds player emotes

Tonnes of custom blocks with custom break sounds.
This is the most basic thing. Up to like a 1000+ custom blocks can be added through block states and infinite custom sounds.

Custom GUIs with easy scrollable UIs
Yeah this ones a little of a workaround, but Mineclub for example has you click those arrows on the right (it's a dynamic scroll thingy)

[vocal cloud]

Yeah but it'd be a nightmare to manage the state for all that

It looks a lot more natural when modded

[worn tundra]

But the upside being being

• No external downloads
• Under 10 mb resource pack
• Easier to join the server and experience the stuff right away

[vocal cloud]

Again, that's not an issue

[worn tundra]

Well yeah but thats just nitpicking. Have you seen the GUIs on MCC Island?

[vocal cloud]

Not nitpicking. It's one of many reasons

[worn tundra]

For which you're ready to sacrifice hundreds of potential players?

There's a reason why all large upcoming servers are using these mechanics

and not mods

[vocal cloud]

Like I said it's not an issue

Rarely has anyone mentioned modded as being a reason they'd rather not play

[worn tundra]

What's the most popular modded server?

[vocal cloud]

No clue. Doesn't matter either

[worn tundra]

Aight

[vocal cloud]

We have 7000 people in our discord with 0 advertising

[worn tundra]

That's nice

[tender shard]

does anyone know a good CLI argument parser for java, similar to getopts in bash?

[civic wind]

I agree with you, modding is trash

[vocal cloud]

Doesn't apache commons have something for that?

[tender shard]

idk, what's it called? 😄

[worn tundra]

Not really trash, has it's own use cases. It's just that there's a higher bar to access a modded server as opposed to a vanilla server.

[vocal cloud]

https://mvnrepository.com/artifact/commons-cli/commons-cli

[tender shard]

thx, that looks promising

yeah that's exactly what I was looking for, thx

[naive bolt]

how do i get all the blocks in an area when i have the leftMark and the rightMark

sorta like worldedit

[chrome beacon]

You loop them

[quaint mantle]

hello, I'm creating a core for a skyblock .... I want to create an island that is not already occupied by another island, what do you recommend? use external plugins? if so, which ones?

[fresh timber]

How do I change the name above a player's head in a Spigot plugin?

[eternal oxide]

PlayerProfile and NMS/packets

[worn tundra]

Recommend for what? Setting the island? Pasting the schematics?

[quaint mantle]

pasting the schematic

[worn tundra]

WorldEdit api

Or similar

[eternal oxide]

Use teh Structure API

A part of Bukkit

[quaint mantle]

with these API can I avoid the two islands being close?

[eternal oxide]

thats upto your code

[quaint mantle]

k

thanks

[fickle mist]

Hi everyone! I have a question here I have like int c = 6
and I need in if what if what if the number of diamonds is equal to c then some actions take place then how to find out how many diamonds the player has in the inventory

[tardy delta]

might use a for loop cuz idk if this is what youre looking for

[quaint mantle]

hey

this is prob super basic

but um

what does
(int i = 0; i < args.length; i++) this mean

in particalarly

what does ++ do ?

oh

so

Can you give me an example like where its used

because i see it used a lot with args/strings and idk if i will need one for my custom enchants plugin

[tardy delta]

kk tysm

[grim ice]

there's a much easier way

just in case you're not using a command, instead the asyncchat event

[eternal oxide]

String.join args

[grim ice]

then split the message like this:
message.split("sendmessage");
this will return an array, just do ur checks then get the [1] index in the array

itll return everything after /sendmessage

[serene sigil]

hi, how do u check if the itemstack u dropped is a shulkerbox with an item inside?

and in Item from?
