imagine someone using hashmaps

and getting confused why it isnt working

cuz he doesnt know that his package thingy is broken

package e.owo.lol.datemepls

when i finish dis ill go continue java dos

becuz this thing is 100% not enough

[burnt sand]

Hi does anyone know how i can update the version of my plugin and upload a new jar

[unreal quartz]

give up and move to brazil

[opal juniper]

no

brazil is bad

Kenya is better

[manic bison]

hey, how could i convert from InetSocketAddress to String ? I've been trying String.valueOf() but it shows me things i dont want to see, i just need to see the standard IP adress format like X.X.X.X

[kindred valley]

hello

[manic bison]

because rn it gives me X-X-X-X.domain.domain.net/X.X.X.X:XXXXX

[kindred valley]

if(kelepce.equals(player.getInventory().getItemInMainHand()))

why this method is not running

[manic bison]

what the f is kelepce

[kindred valley]

hancluffs

mean

[manic bison]

kk

[kindred valley]

and its a custom item

[manic bison]

is it in PlayerInteractEntityEvent

and did you put an Event Handler

and have you registered it in your Javaplugin extends class?

[kindred valley]

yes

[kindred valley]

yes

[kindred valley]

yes

[manic bison]

try sysout'ing some parts of your code so you can see what is fired and what's not

System.out.println("Test1");

[kindred valley]

this part of code is not working

if(kelepce.equals(player.getInventory().getItemInMainHand()))

[quaint mantle]

try isSimilar to ignore item amounts

[kindred valley]

not working

[kindred valley]

i did this at first but didnt work

and i made it .equals

and it is not working either

[quaint mantle]

show where you create kelepce item

[kindred valley]

    public void onClamp(final PlayerInteractAtEntityEvent e) {


        Player player = e.getPlayer();
        final Entity clickedEntity = e.getRightClicked();

        if (clickedEntity instanceof Player) {



            ItemStack kelepce = new ItemStack(Material.TRIPWIRE);
            ItemMeta meta_kelepce = kelepce.getItemMeta();
            meta_kelepce.setDisplayName(ChatColor.GRAY + "Kelepçeler");
            ArrayList<String> lore = new ArrayList<>();
            lore.add(ChatColor.DARK_BLUE + "Polislere Özgüdür");
            lore.add(ChatColor.DARK_BLUE + "Kişileri Kelepçeleyip Soymaya Yarayabilir.");
            meta_kelepce.setLore(lore);
            meta_kelepce.addEnchant(Enchantment.PROTECTION_FALL, 1, true);
            kelepce.setItemMeta(meta_kelepce);

            if(kelepce.equals(player.getInventory().getItemInMainHand())) {



                player.sendMessage("blabalbla");


            }

        }
    }```

[quaint mantle]

show the item in your hand

[kindred valley]

what

[quaint mantle]

send a ss of the item in your hand

Hey, sorry but I'm back with my map problem, actually it works fine but it loads only around the 0:0, even if I select an another region 🤔
https://paste.md-5.net/icayigenac.java

if anyone can help me about it, it would be awesome thnx

[dim bluff]

How do I differenciate between normal golden apple and enchanted golden apple

like what would for example Material egoldenapple = Material.etc be

putting Material.GOLDEN_APPLE, 1, (short)1; just puts an error

[calm whale]

Material.ENCHANTED_GOLDEN_APPLE @dim bluff

you could simply look at Material list to find it

[dim bluff]

it doesnt seem to make the difference

1. my set of wanted materials doesnt even register ENCHANTED_GOLDEN_APPLE as a material. And in game the gapple and enchanted gapple do the same thing

(same cooldown)

[calm whale]

what is your version ?

[dim bluff]

1.8.8

[golden turret]

ye

normal apple

durability of 1

[dim bluff]

how do I make the difference, everywhere is telling me to change durability but none of the codes work

well

Material.GOLDEN_APPLE, 1, (short)1; idk how to do this

[golden turret]

in itemstack constructor

[dim bluff]

do I just change all my materials to itemStacks

[golden turret]

welcom to 1.8

[dim bluff]

bru

nah

naaaaaa

[golden turret]

it depends to

[dim bluff]

😢

[golden turret]

u can keep using materials if yk the items doesnt have data

[dim bluff]

I need the enchanted golden apple

thats it

so I guess everything needs to change for 1item

lit

[calm whale]

what are you trying to achieve ?

[tall dragon]

could also use XMaterial maybe https://github.com/CryptoMorin/XSeries/blob/master/src/main/java/com/cryptomorin/xseries/XMaterial.java

[dim bluff]

I'm just adding cooldowns to eating food

[golden turret]

or wlib

[dim bluff]

everything is done and perfect

just the notch apple 🙂

might just add an if statement

[tall dragon]

XMaterial adds these material in the enum and will automatically parse it to the correct item with durability

but you'll need to change your Materials to XMaterials

[golden turret]

wlib is a copy

[tall dragon]

well any of the solutions work

i have my own class for handling this

[quaint mantle]

can i make a command to verify someone's debit card credentials

[opal juniper]

lmao

[quaint mantle]

LOL

no i forgor what i was gonna ask

im at a restraunt so i cba

something about entity visibility w/o packets

i'll ask later when im more available

[quaint mantle]

if you dont want that huge fucking utility class look at my enum
https://github.com/ImajinDevon/GalaxyShop/blob/master/src/main/java/me/imaginedev/galaxyshop/version/VersionedMaterial.java
change the values to enchanted golden apple and any other

[lament minnow]

Not really help, but why does Spigot still use Gson 2.8.0 when 2.8.8 is the latest?

[quaint mantle]

Yea

probably doesnt add any features needed/performance

[lament minnow]

i at least know that it deprecated jsonparser objects and replaces them with static methods

would that decrease or increase performance

[quaint mantle]

neither

[lament minnow]

Oh.

okay that explains it

[ivory sleet]

Moshi (D

[vivid lily]

Why is playerConnection not a thing?

[hasty prawn]

Are you on 1.17 with Mojmaps

If so it's just connection

[vivid lily]

im on 1.17.1 but not mojmaps

[hasty prawn]

Then it's obfuscated

You'll have to manually look through the mappings to find what it's called.

[lament minnow]

Use the remapped-mojang spigot server for that.

Or do that.

I know that it is b.

[hasty prawn]

Well there you go

[vivid lily]

That's what i thought!

But thanks for confirming

[lament minnow]

you are welcome

[hasty prawn]

Yeah all the Spigot stuff got obfuscated in 1.17 so if you want normal names you have to use Mojmaps and then remap at compile with SpecialSource

[lament minnow]

i can show exactly how to do it

and i recommend it because obfuscations suck ball

[hasty prawn]

Facts

[vivid lily]

i would rather learn the obfuscated stuff

[lament minnow]

ogey

[hasty prawn]

It's definitely a pain to initially setup mojmaps but once you get it

[lament minnow]

i think that they can change between updates though

[hasty prawn]

I wouldn't be surprised if they did

[errant snow]

Hey, so I'm trying to deserialize ItemStacks from a json file. Serializing them seems to work fine, but for some reason deserializing throws and EOFException. I'm not sure why I'm getting an EOFException because my methods seem to be the same as other methods people wrote for similar uses.

Here is my serialization method:

@Nullable
public static String itemStackToBase64(ItemStack item) {
    try {
        ByteArrayOutputStream io = new ByteArrayOutputStream();
        BukkitObjectOutputStream os = new BukkitObjectOutputStream(io);

        os.writeObject(item);
        os.close();
        byte[] serializedObject = io.toByteArray();
        return Base64.getEncoder().encodeToString(serializedObject);
    } catch (final IOException ex) {
        Bukkit.getLogger().severe("Unable to serialize item: " + item);
        ex.printStackTrace();
        return null;
    }
}

And here is my deserialization method:

@Nullable
public static ItemStack base64ToItemStack(String base64) {
    try {
        byte[] serializedObject = Base64.getDecoder().decode(base64);

        ByteArrayInputStream in = new ByteArrayInputStream(serializedObject);
        BukkitObjectInputStream is = new BukkitObjectInputStream(in);

        ItemStack item = (ItemStack) is.readObject();

        is.close();
        return item;
    } catch (final IOException | ClassNotFoundException ex) {
        Bukkit.getLogger().severe("Unable to deserialize item from string: " + base64);
        ex.printStackTrace();
        return null;
    }
}

After adding some print statements, I narrowed it down the the exception being thrown by this line: BukkitObjectInputStream is = new BukkitObjectInputStream(in);

[waxen plinth]

Imagine not going open source

[unreal quartz]

ye it is called licensing it under the GPL and releasing it as free software

[waxen plinth]

GPL??

MIT best license

Get outta here with that viral license shit

[unreal quartz]

that’s what spigot is

I would choose MIT if spigot wasn’t GPL

[waxen plinth]

Choose MIT

[unreal quartz]

but either way it is inconsequential as no one gives a shit anyway and it’s not like I am going to take action against someone violating my license

[granite beacon]

How can I push a minecart at a set speed?
(depending on where the rails are pointing to)

I've been trying by altering the velocity but that just bugs things out due to the different directions

[waxen plinth]

I haven't seen a single case of someone coming after an open source plugin for not being GPL

[granite beacon]

It's driving me up the wall

[waxen plinth]

Yeah I don't have money for a lawyer lmao

That's why I go MIT

Even if someone did violate the license

The worst that really means is they didn't credit me or didn't redistribute the license with the source

Of which neither are a big deal

And in general I just don't really care what people do with it as long as it's not harming me and I like them to credit me, but if they don't that's not a big deal either

[unreal quartz]

likewise

i am a broke uni student, i have other things to be doing rather than caring about how people use plugins i wrote as a way to practice programming

[waxen plinth]

Mhm

[unreal quartz]

doesn’t stop you

that is a monumentally stupid decision

so.. why are you doing it?

in most cases it is malicious

why are you hard coding your own discord webhook into software other people use

[waxen plinth]

You can make paid plugins open source

PlotSquared did that

And they still have buttloads of paid downloads

[unreal quartz]

or.. have people hop into your discord server instead and just tell you

[waxen plinth]

Just put it in config

Seriously

Wait

slfjkgl

[unreal quartz]

how are you going to clarify suggestions if they’re ambiguous

[waxen plinth]

Yeah that's genuinely a really terrible idea

Even with obfuscation the string is still in there

You could very easily use wireshark to get the url

[quaint mantle]

Why are you guys having a full on conversation

[waxen plinth]

And send a bunch of shit to the webhook

[granite beacon]

you guys are having a 2v1. He asked a question...

[waxen plinth]

Just don't do it

[unreal quartz]

because discord channels are designed to allow people to have conversations

[waxen plinth]

Yeah we're telling him not to do it because it is a monumentally stupid idea

Take suggestions in your discord

Without a webhook

[unreal quartz]

and he has a serious security risk with his program design

[waxen plinth]

The only way is to set up a backend server that the plugin would communicate with

[unreal quartz]

why would players be suggesting things for your plugin?

[waxen plinth]

But even if you do that there's no way to easily filter out junk or spam

[unreal quartz]

they go to the server admins to suggest things

they then forward that to you

[granite beacon]

All I'm saying is, you guys sound like you're pressuring him into posting his code as open source when he clearly doesn't want to do that. Not my business/problem tho

[waxen plinth]

We promoted open source but we're beyond that

We're focusing much more on this as a security hole now

[unreal quartz]

then you have not read the whole conversation, I have said like 3 lines to him suggesting open source?

[waxen plinth]

There just isn't one

Unless you use an existing forum

Or discord

[unreal quartz]

just have a gigantic banner on your plugin page linking to your discord server

[waxen plinth]

Just have /suggest show the link to a forum where they can make a request

[granite beacon]

Not here to argue 😄

[waxen plinth]

Or a link to your discord

[granite beacon]

Just curios as to how I can solve my problem

[waxen plinth]

I don't know enough about what you're trying to do to help

[granite beacon]

Yeah no worries, appreciate it regardless 😅

[unreal quartz]

if you want to piss off every user of your plugin, go for it

[silver shuttle]

+1

OH NO

you realize thats 20 times a second for every player moving etc?

and much much more

oh ok

just have a big title and subtitle

and play sounds

particles

maybe tp them into an advertising world

what about making it mandatory for them to join ur discord and link their mc account?

before they can join

just cancel the PrePlayerLoginEvent

[silver shuttle]

^^

and obfuscate your code

lol

[quaint mantle]

?kick @silver shuttle unfunny sexism

[undone axle]

Done. That felt good.

[quaint mantle]

Nope

[hasty prawn]

Wow

[vivid lily]

Anybody know what the obfuscated version of ADD_PLAYER is? (Wrong image)

[granite beacon]

How can I push a minecart at a set speed?
(depending on where the rails are pointing to)

I've been trying by altering the velocity but that just bugs things out due to the different directions

[unreal quartz]

set the velocity to the direction the rails are facing then

[granite beacon]

right but as I said, it bugs out when it hits a curve or anything like that because the minecart's direction switches up

[unreal quartz]

click through, your ide can decompile it

velocities are set a one time thing, not as a constant, so when the direction changes then apply a new velocity respecting the new direction

[vivid lily]

figured it out. its a

[quaint mantle]

A what

[granite beacon]

the thing is that it can't be a one time thing since I want the minecart to move like a payload in overwatch (when players are around)

[vivid lily]

The obfuscated version is a

[quaint mantle]

Get it

because

'a'

[quaint mantle]

why is (Bukkit.getServer()).getServer()

what is that

what

💀

[eternal oxide]

inception

[vivid lily]

@quaint mantleIt was a wrong image

[quaint mantle]

ok but what is

why are you doing that

(Bukkit.getServer()).getServer()

i just don't really know what that is

or why?

inception

[torn oyster]

how do i make projectiles pass through certain players

[unreal quartz]

make all your players watch the matrix

[hexed hatch]

You'd probably have to create your own Arrow entity

[eternal oxide]

You could try adding the arrow entity as a collidable exemption to the player. No idea if it will work, but worth a try.

[torn oyster]

im trying to listen to entity damage event

and teleport arrow forwards

how do i teleport an arrow forwards

in the direction it is going

[eternal oxide]

Just try player.getCollidableExemptions().add(arrow.getUniqueId())

[torn oyster]

does this work on 1.8 lmfao

sorry for using it

how do i tp an arrow forwards

[eternal oxide]

its an entity so entity.teleport

[torn oyster]

how do i make it teleport forwards

proj.teleport(proj.getLocation().multiply(0.1));

prob wrong lol

[hexed hatch]

I don't think those collidable methods work with projectiles tbh

I think projectile collision is some deep nms shit

[eternal oxide]

entity.teleport(entity.getLocation().add(entity.getLocation().getDirection().multiply(2)));

[torn oyster]

how many blocks will that teleport forwards

[eternal oxide]

2, but depend on the speed of the arrow

[torn oyster]

wdym

whats the amount

that will be right behind a player

[eternal oxide]

if the arrow is traveling faster than 1 block per second

actually nm, it shoudl tp it 2 blocks

[torn oyster]

so if i do

[eternal oxide]

remove teh multiply to move it one bloc, or multiply by 1

[torn oyster]

multiply 1

[eternal oxide]

as getDirection() returns a unit vector it will be fine

[torn oyster]

    @EventHandler(priority = EventPriority.HIGH)
    public void onProjectileHitEvent(EntityDamageByEntityEvent e) {
        if (e.getDamager() instanceof Projectile && e.getEntity() instanceof Player) {
            Player damaged = ((Player) e.getEntity());
            Projectile proj = (Projectile) e.getEntity();
            SkyWarsGame m = (SkyWarsGame) MinigameManager.getMinigameManager().getCurrentMinigame();
            
            if (m.getMinigamePlayer(damaged).isGhost()) {
                e.setCancelled(true);
                
                proj.teleport(proj.getLocation().add(proj.getLocation().getDirection().multiply(2)));
            }
        }
    }```

it works

cuz it passes through player

but the person it hits after it passes through (a non-ghost)

doesnt take damage

also pearls dont work with this either

[young knoll]

Perhaps the server ignores it because it thinks it’s already hit someone

You could spawn a new one with the same data I guess

[eternal oxide]

try doing it in the ProjectileHitEvent

[torn oyster]

there is no way to see what it hit tho

[eternal oxide]

of course there is

getHitEntity()

[young knoll]

Might not exist in 1.8

[eternal oxide]

tuff then

[torn oyster]

this doesnt work either

    @EventHandler(priority = EventPriority.HIGH)
    public void onProjectileHitEvent(EntityDamageByEntityEvent e) {
        if (e.getDamager() instanceof Projectile && e.getEntity() instanceof Player) {
            Player damaged = ((Player) e.getEntity());
            Projectile proj = (Projectile) e.getEntity();
            SkyWarsGame m = (SkyWarsGame) MinigameManager.getMinigameManager().getCurrentMinigame();
            
            if (m.getMinigamePlayer(damaged).isGhost()) {
                e.setCancelled(true);
    
                proj.teleport(proj.getLocation().add(proj.getLocation().getDirection().multiply(2)));
                Projectile p = (Projectile) e.getEntity().getWorld().spawnEntity(proj.getLocation(), proj.getType());
                p.setVelocity(proj.getVelocity());
                p.setShooter(proj.getShooter());
                proj.remove();
            }
        }
    }```

[gaunt saffron]

i have a main/bungee server and a node/spigot server

can i using a spigot plugin on the spigot/paper server run bungee comands? i want to send a player back to lobby, using /send player lobby or whatever

[summer heart]

If you have a bungeecord proxy then yes

[gaunt saffron]

okay, any code example/ressource?

[summer heart]

/send is a default bungee command. If you have 2 servers and a bungee server you can do /send <player> <server>

[gaunt saffron]

how would i do that inside bukkit?

i assume if i run /send on a bukkit server it wont work

[summer heart]

yeah then I dont think it would work with bukkit

im not too sure on that one

[young knoll]

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

[gaunt saffron]

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/
found this, no idea if this even works... and let's hope i dont break the bungee... i really hope 5 gigs is enough mem

[young knoll]

Bungee takes like

[gaunt saffron]

thanks !

[young knoll]

1GB per hundreds of players

[gaunt saffron]

oh then im f-ed

[summer heart]

One of the errors in my IDE is ',' or ')' expected:36. I have no idea where to put it xD

p.setVelocity(new Vector(0,64,0)p.getLocation().getDirection());

[gaunt saffron]

time to buy better vps i guess... welll once i scale

[young knoll]

How many freakin players do you have

[cedar laurel]

Is there an event for when Bungeecord shuts down?

[gaunt saffron]

currently, none as i didnt deploy yet, but i wanna have a system pretty safe upto 10k
my nodes can scale infinetly, like, actually no limit, just not sure about bungee 🙄

since bungee is the glue

okay it's not, same error

okay i gotta sleep, please @ me

[quaint mantle]

?paste

[undone axle]

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

[quaint mantle]

That's your reason

[gaunt saffron]

can't access
will use another one like when i wake up.... unless someone can instant solve it @quaint mantle
will type tomorrow

no idea what that means tbh

i dont like java errors

[quaint mantle]

And also instead of bukkit.dispatch command ... "Stop", use Bukkit.shutdown();

[gaunt saffron]

well that's another error 😂
tbh i want smth else than /stop as it's too slow

[quaint mantle]

It's just my suggestion

Use Bukkit.shutdown()

[gaunt saffron]

but yeah, the bungee stuff? any idea?

[quaint mantle]

Not for me

[gaunt saffron]

is there a way to INSTANTLY close the server?

like end the process?

idc about saving, at all

[young knoll]

I mean

Runtime.getRuntime.halt if you really wanted to

You could also interface with an external explosive charge connected via USB

[waxen plinth]

System.exit(0)

[waxen plinth]

This is a better idea though lol

[young knoll]

System.exit still invoked shutdown hooks

Halt does not

[rough jay]

hi, how to set food level more than 20?

[sleek turret]

I dont think you can. I dont think it works like health

[rough jay]

(

[quaint mantle]

@rough jay you can

it is very hacky though

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/entity/FoodLevelChangeEvent.html

use PDCs to handle a namespacedkey "ExtraHunger"

get what im sayin?

🤠

lemme know if you have any questions it can be quite confusing

public class ExtraHungerManager implements Listener {
    public void setExtraHunger(Player p) { ... }

    @EventHandler
    public void onFoodLevelChange(FoodLevelChangeEvent e) {
        //...
    }
}

[young knoll]

I mean that’s kinda how saturation works

Now we have double saturation

[quaint mantle]

except saturation heals you

anyways how do i evaluate a linked list

mathematical evaluation

class Node:
    def __init__(self, root, previous=None, next=None):
        self.root = root
        self.previous = previous
        self.next = next

Hi anyone knows why it cant catch the connect pluginmessage?

    public static void sendPlayerToServer(Player player, String server) {
        try {
            ByteArrayOutputStream b = new ByteArrayOutputStream();
            DataOutputStream out = new DataOutputStream(b);
            out.writeUTF("Connect");
            out.writeUTF(server);
            player.sendPluginMessage(getInstance(), "BungeeCord", b.toByteArray());
            b.close();
            out.close();
            Gui.msg(player, "§7Enviando a: " + "[§4" + server + "§7]");
        } catch (Exception e) {
            player.sendMessage(ChatColor.RED + "Error when trying to connect to " + server);
        }
        //player.sendPluginMessage(Handler.getInstance(), "BungeeCord", b.toByteArray());
    }

I don't get the catch when the server is offline

[quaint mantle]

Because it wont throw an exception If it is offline

[quasi flint]

Can somone tell me whats wron with this line? It just throws an NoSuchElementException

Property property = profile.getProperties().get("textures").iterator().next();

[gritty urchin]

Hey, how would I spawn a mob for a later Minecraft Version. E.g. an axolotl to 1.17 clients on a 1.16.5 Server running ViaVersion?

[quasi flint]

that sounds tricky, because i dont think the 1.15 client would understand the axolotl entity

not sure thi#

tho

[gritty urchin]

For 1.17 client?

[opal juniper]

you cannot spawn newer mobs for older clients

they would shit the bed or default to a single mob type

[gritty urchin]

I didnt mention an older client

[opal juniper]

ah ok

i miss read

[gritty urchin]

Spawn an axolotl to 1.17 clients on a 1.16.5 Server running ViaVersion.

[opal juniper]

no there is no way to spawn a mob that doesn’t exist as far as i know

[gritty urchin]

Not with 1.17 NMS or is it all server dependent?

[opal juniper]

the fact that you are on a 1.16.5 server is the issue

it has no idea what an axolotl

[gritty urchin]

Ah ok

But the 1.17 client does, so is there a way to recreate it?

[opal juniper]

with a custom client maybe

idk what the spawn entity fields are

gimme a sec

you could probably fake it tbh

you just need to fill in all those fields

[gritty urchin]

Ah ok thanks.

But would the 1.16.5 server recognise it as a valid entity. Not in displaying it for a 1.16.5 client but that it exists and can be removed.

[opal juniper]

you will probably have to work that out urself

[gritty urchin]

Alr thanks

[quasi flint]

Have you read this? https://www.javatpoint.com/nosuchelementexception-in-java

@quasi flint what're you trying to do

Changing my NPC's skin

[grim ice]

i hate nms sori

[lavish hemlock]

You should check if the iterator contains anything

Also, why use the iterator?

Just do .get(0) to get at the first index.

You'll need to check that get() doesn't return empty though.

This is extremely messy

and you're naming stuff horribly

[sterile dragon]

yeaah ik lol

[lavish hemlock]

oh god

[crude charm]

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[lavish hemlock]

The last one is also just outdated and bad :p

[crude charm]

...

The official java docs... bad?

[lavish hemlock]

It is outdated, okay? It's only up to date for Java 8.

And:

• It's confusing for beginners.
• Hard to read due to the styling of the page.
• Designed for enterprise developers.
• And kinda hard to navigate?

[crude charm]

Idk what you're on about bud.

Noones problem that beginners cant read it

they are beginners

[lavish hemlock]

It's literally a tutorial.

If someone trying to learn the language can't read the tutorial.

It has missed the point of being a tutorial.

[crude charm]

You need to learn to read a java to be able to understand it

It's not supposed to be a tutorial

[lavish hemlock]

It is literally the official source. Before other guides were made, how would someone learn how to read Java?

[crude charm]

It's pretty obv that docs aren't a tutorial

Doesn't mean you dont learn alot of them

[lavish hemlock]

And it is a tutorial. All signs point to it being designed as one.

[crude charm]

/ should read them

/ should check them

idk how this is even an argument

[lavish hemlock]

The URL says tutorial, the The Java Tutorials have been written for JDK 8., etc.

And it literally fucking says

The Java:tm: Tutorials

[sterile dragon]

at the start i was just asking how to replace this player.getScoreboard().getEntryTeam(getName()) because it don't work x)

[lavish hemlock]

at the top

But you know, it's a horrible idea to teach someone OOP concepts before teaching them the basics of your language.
You should teach them OOP concepts when they have the ability to process OOP concepts.

I've known multiple Java beginners who struggle with OOP because they're pushed into it too early.

[crude charm]

first learn java

then make a util for scoreboards / use an existing one

[crude charm]

m8 idk why you're still arguing that java docs are useless

[lavish hemlock]

They're not useless.

They're just badly designed.

It makes them harder to be used.

[crude charm]

no

[lavish hemlock]

And ftr, calling them "Java docs" is incredibly misleading as "Javadocs" exist.

[crude charm]

you just need to know how to read them

[lavish hemlock]

I literally just went over this point, Zoi.

[crude charm]

whatever

I give up

[lavish hemlock]

You are terrible at debating.

[crude charm]

Its not a debate

like

lmfao

I really dont care

You just look like an idiot

[lavish hemlock]

I guess it could be more accurately described as an "argument"

[ivory sleet]

Guys chill (:

OOP sucks end of discussion

[grim ice]

can someone explain Encapsulation, Abstraction, Inheritance, and Polymorphism better? google makes it weird

[ivory sleet]

maowcraft can

And ZoiBox (:

[crude charm]

https://www.javatpoint.com/encapsulation
https://www.w3schools.com/java/java_abstract.asp
https://www.w3schools.com/java/java_inheritance.asp
https://www.w3schools.com/java/java_polymorphism.asp

[lavish hemlock]

But my point is that the Java tutorials were advertised as tutorials (judging by them being literally called "The Java Tutorials" and being referred to as "The Java Tutorials"), therefore they should be judged as tutorials instead of docs (the JLS is more documentative anyways), and having to learn how to read the tutorials in the first place is just counterproductive as it steers people away from said tutorials and makes those trying to use them struggle more with using them. They're poorly designed due to their outdated nature, bad structure, and unwelcoming visuals (which is part of them being outdated, as they haven't been updated to match modern style standards). If you need to learn how to read Java before you can even understand the concepts in Java, how are they a good set of tutorials? In order to read Java in the first place, you need a tutorial to teach you how to read Java, and considering Oracle made this tutorial, it's the official first source of information, very likely the first source someone may see unless they find Codecademy or other sources first, which means they can't just "learn Java before they can learn Java." You see how illogical that statement is?

[crude charm]

My man really just wrote the bible lmfao

[lavish hemlock]

And with this sentence, I truly know what kind of person you are. Good day/afternoon/night, I'm done arguing with you.

[grim ice]

@lavish hemlock > Zoibox here

[ivory sleet]

Guys just stop ffs

[crude charm]

ikr

just give up

[lavish hemlock]

Encapsulation is the concept of only showing the most important, front-facing parts of your program to users, AKA for example, hiding the internal parts so that it's easier to understand which parts are part of a library.

[crude charm]

I dont care

[grim ice]

o

like making private variables then making getters for them?

[lavish hemlock]

Yeah, that's a form of encapsulation as you're encapsulating the fields, making it easier to make changes to the code in the future in case that field changes.

[grim ice]

so the class that has actual functionality uses getters instead of direct access?

Oh I see

[crude charm]

@grim ice

[grim ice]

I don't get polymorphism well though

[lavish hemlock]

Abstraction is then for splitting your code into multiple "abstractions," such as how Java's standard library has List, AbstractList, and then ArrayList. It allows for reducing the amount of code reuse.

[grim ice]

You assumed I haven't read those, lol

[lavish hemlock]

For example, List defines what lists should do.
AbstractList implements a lot of common behaviour for those lists.
And then ArrayList implements specific behaviour.

[grim ice]

oh so like

the relationship between an engine and a car

a car would be an abstract class

and the engine would extend maybe a Part class

that extends a car class

right

[lavish hemlock]

Well, you wouldn't want your car parts to extend the car.

You'd want your car to contain the car parts.

[grim ice]

o

but its containing them like that, and you're also following SRP right?

[lavish hemlock]

Oh I'm sorry actually I gave you bad definitions

Okay so Encapsulation is bundling things into single pieces.

And Abstraction is hiding the unimportant details.

[grim ice]

How so? for abstraction

[lavish hemlock]

In the way I explained with my previous, wrong definition of Encapsulation.

Meanwhile, that Abstraction definition is much closer to Inheritance

For Inheritance I think I'll provide a code example

public class Car implements Vehicle {
    ...
}

In this situation, Car inherits the properties of Vehicle.
Therefore, a Car is a Vehicle.
This also means Car must "implement" what Vehicle has "defined."

[grim ice]

o

Vehicle has to be abstract, right?

[lavish hemlock]

Defining is like creating how something should be interacted with

And Implementing is creating what happens when that something is interacted with

[lavish hemlock]

It's an interface, so it's abstract by default, yes.

And Polymorphism plays off of Inheritance

For example, say you want to give your Person a Vehicle.

lemme just write a code example

public class Person {
    public void giveVehicle(Vehicle vehicle) {
       // implementation logic isn't important here ...
    }
}

Since Car implements Vehicle (it is a subclass of Vehicle), you can pass a Car to the parameters of giveVehicle

myPerson.giveVehicle(new Car()); for example

and imagine we have a Boat that also implements Vehicle, well, myPerson.giveVehicle(new Boat()); works too

[grim ice]

oh so polymorphism lets a method work for different uses? like a murder method happening with different tools,
like public void murderSomeone(Tool tool){
guy.murder(tool);

[lavish hemlock]

Yeah!

And usually

[crude charm]

Is it possible to have a custom X marks the spot location on a map without using nms or should I make a custom map image?

[lavish hemlock]

Since you don't know what tool was passed unless you check (like with instanceof), you'd probably just want to use what methods are already on Tool.

a more involved example would be

[lucid bane]

guys i hav a question
i cant use World#getKey() in 1.16.5 spigot and dunno why

[lavish hemlock]

public void murder(Tool tool) {
    // 'tool' can only be used to access what Tool has.
    // Let's check and see if the Tool is a knife.
    if (tool instanceof Knife) {
        Knife knife = (Knife) tool; // Here we cast our 'tool' to a Knife, since we now know it's a Knife.
        // Now 'knife' can access both what Tool has and what Knife has.
        // ... go on to murder some poor fellow if you want ...
    }
}

[grim ice]

o

i see thank you

now murder is easier i understand oop more now :D

[lavish hemlock]

You're welcome

[lucid bane]

oh it was paper i saw

sry

[lavish hemlock]

OOP is pretty weird overall but it does help to know it if you're learning Java since it makes understanding code and library development easier.

[summer scroll]

Is there a way to detect when player tries to teleport with a passenger? Now teleport event isn't being called at all because somehow it's cancelled on the client, idk how to explain it properly.

[grim ice]

what are passengers

[lavish hemlock]

Feel free to message me if you have more questions @grim ice

[grim ice]

o sure

[summer scroll]

basically an entity that rides the player

[novel basin]

guys i'm coding a plugin that when a player run a command all compasses in that world will point toward a player's location but i cant get all compasses in that world to point toward that player can someone help me (sorry for my bad english skill)

[lavish hemlock]

You making a Manhunt plugin or something?

I probably can't offer advice but I'm just curious.

[novel basin]

yeah but i dont want to pay 20 bucks

[lavish hemlock]

That's fair.

[lost matrix]

There are several approaches to this problem.

[lavish hemlock]

Also your English is fine, you just need to fix your capitalization and run-on sentences lol.

[novel basin]

;D

[lost matrix]

The problem is that you cant get all compasses in a world. But what you can get are all compasses in the world
any player is currently holding.

[novel basin]

yeah that's all I need

[summer scroll]

Can you somehow detect everytime Player#teleport method is being used?

[grim ice]

@lost matrix do you think liskov thingy is really necessary

its confusing on how to follow

[tall dragon]

@summer scroll im pretty sure EntityTeleportEvent will be fired

but im not completely sure

[lost matrix]

Ok for that you need to:

1. Get all players in this world.
2. Iterate over them and get the inventory of each
3. Iterate over each item in their inventory
4. Check if its not null and of type COMPASS
5. Get the ItemMeta of that ItemStack
6. Cast it to CompassMeta
7. Set the lodestone of that compass to a Location
8. Put the CompassMeta back on the ItemStack

[lost matrix]

You mean the liskov substitution principle?

[grim ice]

yes

[novel basin]

how can i get all players it that world

[summer scroll]

I'm not sure about that one either, but what entity do you think will fired that event? passenger or the player?

[lost matrix]

I mean... you dont need to understand it in detail. Its something that will evolve logically if you
just program for a bit.

[lavish hemlock]

Probably by accessing the world and then accessing a list of players?

[grim ice]

o

[lost matrix]

World#getPlayers()

[lavish hemlock]

^

[tall dragon]

maybe both actualy

[novel basin]

ok ill try

[lavish hemlock]

And you can get the World from the server, but you probably knew that already.

[tall dragon]

im pretty sure the event will fire for any entity that teleports >8 blocks at once

[summer scroll]

Doesn't make sense because PlayerTeleportEvent isn't being called at all.

[lost matrix]

Better get the World from the Player that executed the command

[opal juniper]

Banner banner = (Banner) block.getState();

``` anyone know why this does nothing?

[grim ice]

https://www.educative.io/edpresso/what-are-the-solid-principles-in-java
in the Interface segregation principle section (4.) What would be a fix for their problem they showed?

[lavish hemlock]

Huh, aight.

[vagrant stratus]

just so you guys know, we have threads available.
So ya know, use them lol

[ivory sleet]

Might have to update

[lost matrix]

Call BlockState#update(true)

[grim ice]

I Thought of making multiple abstract interfaces and implement each of the ones they need

[opal juniper]

okee

[grim ice]

and leave the other ones

[lost matrix]

Just noticed

[grim ice]

but it looks like a dumb idea

[vagrant stratus]

more people need to notice lol.
So many people complained and it's not even being used 😂

[lavish hemlock]

But Optic, aren't threads "useless" according to everyone I've ever known? 😢

[opal juniper]

thanks

[ivory sleet]

The general rule of interface segregation is to destruct big ones into smaller ones

Mainly because of code reusability

[vagrant stratus]

better than the current mess that is this channel don't you think? 😛

[grim ice]

wait nvm asbtract interfaces cant provide code

[lavish hemlock]

Actttuaaaalllyyy

[ivory sleet]

They can have concrete implementations

[lavish hemlock]

They can

default or static

[grim ice]

o

[lost matrix]

Btw tell md to open admissions for the discord helper role pls <3. I would be glad to apply.

[grim ice]

default abstract interface?

[vagrant stratus]

I don't think we need more helpers atm, he'll most likely re-open them if needed though

[lavish hemlock]

default states that a method in an interface has an implementation but can still be overridden.
static is just static, you get it.

[grim ice]

static means it can be instaniated once right

fuck it my spelling died

[ivory sleet]

I strongly urge anyone here who needs help with their issue to open a thread, now when it’s actually available. With that being said I suggest naming your thread the question you’re asking.

[lavish hemlock]

Lemme give an example

public interface MyInterface {
    default void concreteMethod() {
        // This method has an implementation on an interface.
        // This means you can still implement it on subclasses but that it's not strictly necessary.
    }

    static void staticMethod() {
        // This method has a static implementation on an interface.
        // This means you access it via the class instead of an instance of the class (which you'd get from a subclass).
        // For example: MyInterface.staticMethod()
    }
}

staticMethod also can't be overridden by a class that implements MyInterface, like all static methods.

and you can't access staticMethod from a MyInterface subclass.

meaning MySubclass implements MyInterface doesn't permit MySubclass.staticMethod()

[ivory sleet]

You can still call it from the subclass but ye

Not overridable

[lavish hemlock]

really? I thought that was something they strictly avoided bc it was "too confusing"

maybe that was just the overriding of a static method via abstract static or smthn

[ivory sleet]

Yeah hmm

You got me unsure also now

[lavish hemlock]

gimme a sec

[summer scroll]

Can you somehow detect when specific method is used?

[lavish hemlock]

Depends. Does the method belong to your class or someone else's?

[summer scroll]

From the spigot api, I want to detect everytime Player#teleport method used

[lavish hemlock]

If it belongs to your class, then it's just an easily method call to say "hey, this method was used."
If it belongs to someone else, they'd have to give you an API for that.

[summer scroll]

I cannot think a better way to handle teleportation issues when trying to teleport with passenger.

[ivory sleet]

How to make a random dungeon generator?

[summer scroll]

Also, teleport event doesn't get called, that's why it's so tricky.

[lavish hemlock]

Yeah I was right.

[ivory sleet]

Oh what the

Alright ain’t complaining lol

[lavish hemlock]

Fun fact though:

I'm pretty sure you can still call it as fuck() WITHIN the class, you just can't specify the class beforehand.

[ivory sleet]

Yeah

[lavish hemlock]

Since you're allowed to do that with fields.

Which I only know because people implement ASM's Opcodes interface

Spoiler: Don't do that.

Just statically import all the fields from Opcodes as it's legitimately faster and has the same result.

Hi, I got a small problem.
If i use ItemStack[] content = ((List<ItemStack>) Main.getInstance().getKluizenConfig().get("Kluizen." + Locatie + ".items")).toArray(new ItemStack[0]); inv.setContents(content); this, It will open once, But if i try to reopen it i will get the error [Lorg.bukkit.inventory.ItemStack; cannot be cast to java.util.List

[lost matrix]

If you want to apply something to one exact player and make it hard coded then sure. But why? Use config instead.

[lost matrix]

You probably save an ItemStack into that config path when the inventory closes.

[tardy delta]

codedreds tutorial xd

[opal juniper]

is there an event for when a block gets powered?

[torn shuttle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/block/BlockRedstoneEvent.html as close as it gets

seemingly

[opal juniper]

hmm yeah

thats annoying

ok thanks

[torn shuttle]

tbf these kind of events can quickly lead to big performance issues

[opal juniper]

PlayerMoveEvent? xD

but yes

ik what you mean

[torn shuttle]

MobMoveEvent

[opal juniper]

i wish there was an EntityMoveEvent

but, there is not

[torn shuttle]

I don't, it would take .1 seconds for half the plugins in spigot to suddenly take tps down to 7

you're better off scanning the actual thing you want to do directly

then you can add your own events upon detection like I did

I wonder if there would be interest in submitting a PR for an enter combat and leave combat event for mobs

[summer scroll]

EntityMoveEvent damn, sound so expensive xd.

[opal juniper]

yes

[lost matrix]

You can actually write one your own by using a packet listener XD

[opal juniper]

but there is like a million times i have need it

yesa

thats the best way tbh

dont work if noones online doe

/near it

[lost matrix]

You just need to be careful because the move packet gets sent to several players at once

[lost matrix]

Yeah.

[summer scroll]

What about checking entity location every x second

[opal juniper]

runnable would work

not as accurate tho

[quasi flint]

now for a god unknown reason it says it cant reach the session server

cant a 1.15 thing pull from the api server anymore or my code completly brocken

[tardy delta]

is there a way to force java to update the value of a variable every time it gets called?

[opal juniper]

what?

[summer scroll]

create a method to get the value maybe

[tardy delta]

hmm yea

[lost matrix]

Yes. With a proxy accessor.

[tardy delta]

😵‍💫

never heard of that

[lost matrix]

Example:

  private final MutableInt number = new MutableInt(0);

  public int getNumberValue() {
    int value = number.intValue();
    number.increment();
    return value;
  }

But this heavily violates several clean code principles. You dont want to have
side effects on a method.

A method should do exactly one thing.

[summer scroll]

Can you just make int field but not final and modify it?

same thing but yeah

[opal juniper]

how does one go about adding to spigot, do i have to fork bukkit & craftbukkit and then clone them. then commit to them and push them back? then some hacking on the jira to open a pr?

lmao

[grim ice]

why

are you

naming variables like thaat

[gaunt saffron]

number_of_players_left ?

[grim ice]

yes

like

thats half constant half variable

lol

[narrow furnace]

call it playersLeft

[quaint mantle]

@gaunt saffron in java its camelCase

[grim ice]

@narrow furnace btw i finished the rest of mooc

[gaunt saffron]

i suck at naming things, better don't open a large python or js project of mine

[narrow furnace]

guy that was like a day

thats a 14 week course yk

[grim ice]

yes i know almost everything

[narrow furnace]

u did all the exercises?

[grim ice]

lmao 14 week for that small shit

no

[narrow furnace]

no?

[grim ice]

bro

they teach u about importing and packages

at part 11

???????????????

[narrow furnace]

wym u didnt do the exercises

[grim ice]

actual fuck?

[narrow furnace]

thats the course

if u didnt do them u didnt do the course

...

[grim ice]

how

[narrow furnace]

its not a book

u dont just read it

the reading is just a short description

of the exercise

[grim ice]

breh

[paper viper]

honestly just use code academy

https://www.codecademy.com/courses/java-for-programmers/articles/welcome-to-java-for-programmers

very good user interface

interactive, and you can learn with other people

choose something and learn it

dont give up in the middle

[narrow furnace]

if u read the homework questions and didnt write the answers, u get a 0% no?

[ivory sleet]

Pulse r u joining the code jam?

[quaint mantle]

wish there were courses that know you already have a lot of experience

[paper viper]

wait when

cause i wanna

lol

[ivory sleet]

HelpChat

Very soon

It’s team of pairs

[quaint mantle]

what is it?

[grim ice]

wats dat

[paper viper]

Yea

[ivory sleet]

So if you do I’d like to be your mate if you’re not taken already

[paper viper]

Oo epic

[ivory sleet]

(:

[narrow furnace]

@grim ice did u do any of the course

[chrome beacon]

👀 code jam

[grim ice]

wdym

[narrow furnace]

what did u do

[grim ice]

i read the stuff and i already know it

[narrow furnace]

oh good so u wont be asking in here for stuff?

[grim ice]

the stuff there arent what i ask these days i guess

[narrow furnace]

cause i know a lot of the things you ask are for sure in that course

[grim ice]

except generics

that i didnt even profit from the website

they dont even tell u what that means and this means

i had to go google it

[paper viper]

alright lets test your knowledge then

[narrow furnace]

you did 0% of the exercises

[paper viper]

on the important stuff

[grim ice]

ok

[narrow furnace]

you got 0% on the course

thats a F-----

[paper viper]

what is a constructor

dont search anything up

[grim ice]

sure

[paper viper]

you shouldnt have to take this long

[quaint mantle]

Lmao

[grim ice]

its a method that runs when u instantiate its in

[gaunt saffron]

please?

[grim ice]

idk how to write instantite

[quaint mantle]

horrible explanation

[paper viper]

yea

[grim ice]

lol but i still know how to use it

[chrome beacon]

You're using this in a lambada. This is refering to the lambada and not your main class

[paper viper]

2Hex, what is static? And why should you use it sometimes, but sometimes not

that might be a bit too complicated but idk

[grim ice]

its to make something get instanitaized once

[paper viper]

cause it has some design involved

[quaint mantle]

horrible

wrong

[grim ice]

lmao

[paper viper]

bruh what

[torn shuttle]

oh god running buildtools is miserable with this internet speed

[grim ice]

thats what i heard though

[toxic mesa]

bump

[narrow furnace]

no thats in the course

🙂

[paper viper]

Lol

Then you should know

[narrow furnace]

which he did

apparantly

[grim ice]

what

what part??

[paper viper]

lol u didnt do it

[chrome beacon]

It's called Flying

Or are you on 1.17?

[toxic mesa]

ye 1.17

[grim ice]

tell me

the part

its in

[narrow furnace]

how long did the 14 week course take you

[quaint mantle]

static is a modifier to allow access without an instance, it should be used for utilities, constants, or singleton design patterns

[chrome beacon]

You will have to use the Position packet then

[grim ice]

^

[narrow furnace]

idk lmao i did it 2 years ago

[grim ice]

how do u know its there then bro

[quaint mantle]

@paper viper yes

[narrow furnace]

because i know what static is

[grim ice]

if you find it ill redo the whole thing from zero

[narrow furnace]

redo?

[gaunt saffron]

im looking at the code and examples and docs, can you tell me at least which line you mean?

[narrow furnace]

u cant redo if u didnt do in the first place

[paper viper]

Yeah. and also the keyword means directly "attaining to the class", or "part of the class" (but not instances) you get the idea

[grim ice]

yes, with the exercices

[toxic mesa]

Pretty sure that position sends the position of the player every 20 ticks right?
Wanted to use the other packet to detect lag, do u know if there is any other packet that is being send every tick?

[quaint mantle]

@paper viper look at hereteres plugins

fucking bombarded with annotations

[jade perch]

https://github.com/heretere/hpwp/blob/master/src/main/java/com/heretere/hpwp/PerWorldPlugins.java

that's beautiful

and if you say otherwise

you're just wrong

[quaint mantle]

plugin.yml

[paper viper]

@Plugin(name = "HPWP", version = "VERSION")
@ApiVersion(ApiVersion.Target.v1_13)
@LogPrefix("HPWP")
@Author("Heretere")
@Website("heretere.com")
@LoadOrder(PluginLoadOrder.STARTUP)
@Permission(name = "hpwp.events", desc = "Allows /pwp events", defaultValue = PermissionDefault.OP)
@Permission(name = "hpwp.gui", desc = "Allows use of /pwp gui", defaultValue = PermissionDefault.OP)
@Permission(name = "hpwp.notify", desc = "Receive update notifications", defaultValue = PermissionDefault.OP)
@Permission(
    name = "hpwp.bypass.chat",
    desc = "Send and see all chat tunnels",
    defaultValue = PermissionDefault.FALSE
)
@Permission(
    name = "hpwp.bypass.commands",
    desc = "Execute all commands even for disabled plugins",
    defaultValue = PermissionDefault.FALSE
)
@Permission(
    name = "hpwp.*",
    desc = "Wildcard hpwp permission",
    defaultValue = PermissionDefault.OP,
    children = {
        @ChildPermission(name = "hpwp.events"),
        @ChildPermission(name = "hpwp.gui"),
        @ChildPermission(name = "hpwp.notify") }
)
@Permission(
    name = "hpwp.bypass.*",
    desc = "Wildcard hpwp bypass permission",
    defaultValue = PermissionDefault.FALSE,
    children = {
        @ChildPermission(name = "hpwp.bypass.commands"),
        @ChildPermission(name = "hpwp.bypass.chat")
    }
)

[quaint mantle]

lmao

[chrome beacon]

Movement packets will be send more than every tick regardless of what you do

[paper viper]

https://tenor.com/view/something-wrong-i-can-feel-it-eminem-rapgod-somethings-wrong-wrong-feeling-gif-20025994

[quaint mantle]

like 20 lines of pure annotation

[narrow furnace]

from the course website

[grim ice]

what part

[jade perch]

Guess who doesn't need need a plugin.yml anymore

this guy

[toxic mesa]

So I could use it to detect lag?

[narrow furnace]

https://java-programming.mooc.fi/part-7/2-algorithms

[chrome beacon]

Wdym?

[grim ice]

i mean

i didnt read every single letter

[narrow furnace]

i did

[grim ice]

it seemed like math bro

[chrome beacon]

Why are you detecting lag?

[quaint mantle]

class Node:
    def __init__(self, root, previous=None, next=None):
        self.root = root
        self.previous = previous
        self.next = next

class LinkedList:
    def __init__(self):
        self.front = None
        self.tail = None
    
    def add(self, token) -> None:
        node = Node(root=token, previous=self.tail)
        
        if self.front == None:
            self.front = node
            
        if self.tail != None:
            self.tail.next = node
            
        self.tail = node

how do I sort and evaluate this list

[grim ice]

THEY PUT THAT THING INSIDE OF A MATH LESSON

BRUh

[jade perch]

google merge sort

[grim ice]

u cant blame me dude

i mean u can

[toxic mesa]

Cuz I want to detect client side/connection lag, I googled for a bit and found that the PacketPlayInFlying gets send every tick and because of that you can use it to detect the player lagging

[quaint mantle]

i mean by operator precedence

[narrow furnace]

the codecademy one pulsebeat suggested is shorter

if u want to do that instead

[quaint mantle]

i could give you a java lesson better than codecamp

[chrome beacon]

Aight. Just be aware that spoofing that is easy

[toxic mesa]

Am aware

[narrow furnace]

codecademy really just teaches a languages syntax

[quaint mantle]

right

[narrow furnace]

ive done their javascript course but im hardly a web dev rn lol

[jade perch]

and?

[toxic mesa]

Could I use the position packet to do the same tho? (detect lag)

does it get send every tick?

[paper viper]

yea i only suggested it cause its interactive

and forces them to do it step by step

[grim ice]

@paper viper ok give me another question if u dont mind

[chrome beacon]

Position in Protocollib is 3 different things bundled. Try the ground packet

[toxic mesa]

Alright, tysm

[grim ice]

to be honest

i cant even blame myself. their whole thing is not organized, they throw important shit inside of useless and common stuff

its painful to even read it

[paper viper]

stop complaining

suck it up, and learn it

[grim ice]

so many examples and its order is ded

[paper viper]

you are clearly only a beginner

[grim ice]

ok

[paper viper]

you have the resources and tools to learn

[narrow furnace]

coding is difficult

we get it

[paper viper]

dont complain

[grim ice]

ok just another question

[paper viper]

we've all been through this too

[jade perch]

Maybe you'll find it more fun to make up your own projects

that's what I did

Make em up and research till it's done

[paper viper]

I first learned Processing, and created my own games

then I learned java, and coded my first Java project for a friend

it was shit, but i learned a lot

Then I found out about plugins, and decided to try them

[grim ice]

pulsebeat

[grim ice]

e

ill use codecademy but just answer that

[paper viper]

answer what question

[narrow furnace]

if u want questions

[grim ice]

pls another questin

[narrow furnace]

leetcode.com

[grim ice]

wait

i cant skip in codecademy???

[narrow furnace]

is that what you were going to do

to learn

skip the learning

nice one

[grim ice]

no like

i dotn wanna know how to add comments or sout ;-;

[narrow furnace]

you did a 14 week course in a day did you not? surely you can handle this

[grim ice]

i mean at least their stuff are organized

[narrow furnace]

you mean at least it holds your hand and gives you hints..

i tried System.exit(0);
i assume i have todo bukkit.shutdown...
is there a way to stop the server EVEN FASTER?
i don't care about keeping the data, it all all corrupt, just stop asap

[paper viper]

Why?

Just why

[jade perch]

Press the power button on the machine 🙂

[paper viper]

You gotta be kidding me with System.exit

[gaunt saffron]

lemme call orcale

[paper viper]

you're joking right

[gaunt saffron]

no? why?

[paper viper]

System.exit will not save data

thats how you get data corruption

lol

[gaunt saffron]

yes i want thta

close asap

[jade perch]

He said he doesn't care

[paper viper]

Lmfao

[gaunt saffron]

1s saved is goood

[narrow furnace]

why do you want to corrupt your server

[gaunt saffron]

less than idc really

[narrow furnace]

tf

[paper viper]

Have you tried Thread.kill

lol

[grim ice]

but wtf

class Conditionals {
  public static void main(String[] args) { 
    boolean breakfastTime = false;
    boolean lunchTime = false;
    boolean dinnerTime = true;
    if (breakfastTime) {
      System.out.println("Let's have waffles!");
    } else if (lunchTime) {
       System.out.println("Let's have sandwiches!");
    } else if (dinnerTime) {
       System.out.println("Let's have pizza!");
    } else {
       System.out.println("It's not time to eat!");
    }
  }
}```

[gaunt saffron]

i can try

[grim ice]

why so many else ifs

[chrome beacon]

You can use the ProccessHandle from Java9+ and kill Java

[grim ice]

is that good or bad

[gaunt saffron]

ugh, example?

[paper viper]

That seems fine

[gaunt saffron]

i want it dead asap

[gaunt saffron]

my start comnmand is rm -rf

[narrow furnace]

👀

rm -rf /

[gaunt saffron]

yupp

im masively scaling minecraft

[chrome beacon]

https://docs.oracle.com/javase/9/docs/api/java/lang/ProcessHandle.html

[gaunt saffron]

destroyForcibly​()?

[chrome beacon]

Use allProcesses​() and filter it and find your java instance then use destroyForcibly()

[paper viper]

Yes

lol

[gaunt saffron]

lemme try

[paper viper]

also use parallel computing

to loop through the processes

if u want quick

[chrome beacon]

looks like you could try using current()

[gaunt saffron]

oh, current would work?

[paper viper]

In that case ig you could do that
