There’s PlayerBucketEmptyEvent

[summer scroll]

Oh didn't know that, that's nice.

[exotic obsidian]

i tried this

@EventHandler
public void onBucketEmpty(PlayerBucketEmptyEvent event) {
org.bukkit.block.Block clickedBlock = event.getBlockClicked();

    if (event.getBucket() == Material.LAVA_BUCKET) {
        new BukkitRunnable() {
            @Override
            public void run() {
                if (clickedBlock.getType() == Material.LAVA) {
                    clickedBlock.setType(Material.AIR);
                }
            }
        }.runTaskLater(Main.getInstance(), 15 * 20);
    }
}

but it is not work with me

@summer scroll

@young knoll

[worthy yarrow]

tf am I looking at

What do you need a task for when placing lava on lava?

[exotic obsidian]

Logic error

[summer scroll]

You need to get the block where the lava is placed.

In that event you can get the block and the block faces.

[exotic obsidian]

you mean this event.getBlockClicked().getRelative(event.getBlockFace() ?

[summer scroll]

The lava is not placed on the clicked block.

[summer scroll]

That's right!

[exotic obsidian]

but i already try this now xd

but not work

                        event.getBlockClicked().getRelative(event.getBlockFace()).setType(Material.AIR);
                    }

[summer scroll]

You can format the code using in discord with this btw

put java too in the formatting

[summer scroll]

Can I get your full code please?

[exotic obsidian]

    @EventHandler
    public void onBucketEmpty(PlayerBucketEmptyEvent event) {
        if (event.getBucket() == Material.LAVA_BUCKET) {
            new BukkitRunnable() {
                @Override
                public void run() {
                    if (event.getBlockClicked().getRelative(event.getBlockFace()).getType() == Material.LAVA) {
                        event.getBlockClicked().getRelative(event.getBlockFace()).setType(Material.AIR);
                    }
                }
            }.runTaskLater(Main.getInstance(), 15 * 20);
        }
    }

[exotic obsidian]

sure!

[summer scroll]

Store the block in a variable so it's easier to read, also maybe you can debug the material type of the block.

You need to make sure if the task is even called.

[exotic obsidian]

    @EventHandler
    public void onBucketEmpty(PlayerBucketEmptyEvent event) {
        org.bukkit.block.Block block = event.getBlockClicked().getRelative(event.getBlockFace());
        if (event.getBucket() == Material.LAVA_BUCKET) {
            new BukkitRunnable() {
                @Override
                public void run() {
                    event.getPlayer().sendMessage("wlc");
                    if (block.getType() == Material.LAVA) {
                        block.setType(Material.AIR);
                        event.getPlayer().sendMessage("done!");
                    }
                }
            }.runTaskLater(Main.getInstance(), 15 * 20);
        }
    }

the first message was sended but the message that in if block doesn't sended.

@summer scroll

[summer scroll]

That's nice, now you know that the task is called and running properly, now debug the material type of the block, so debug the Block#getType

[exotic obsidian]

yea

[summer scroll]

I think you might need to store the variable inside the task.

The block variable.

[exotic obsidian]

the problem come from gettype method

[exotic obsidian]

i will try

[summer scroll]

So on your code above, the block is before the lava is even placed, so it will be Air if I'm not wrong

[exotic obsidian]

nah

i tried to put the block variable inside the task but i got the same result

[summer scroll]

There is block, and blockClicked, I don't know what's the difference.

[exotic obsidian]

but when i remove the condition of getType the code is work

[summer scroll]

What does the getType says?

[exotic obsidian]

not says anything

but i tried to remove it

and try

and it is works

    @EventHandler
    public void onBucketEmpty(PlayerBucketEmptyEvent event) {
        org.bukkit.block.Block block = event.getBlockClicked().getRelative(event.getBlockFace());
        if (event.getBucket() == Material.LAVA_BUCKET) {
            new BukkitRunnable() {
                @Override
                public void run() {
                    block.setType(Material.AIR);
                    event.getPlayer().sendMessage("done!");
                }
            }.runTaskLater(Main.getInstance(), 15 * 20);
        }
    }

[summer scroll]

Interesting, can you maybe try to debug what is the type?

Like debug the block.getType() in the task.

But you need the variable block inside the task.

Because what you have here is not ideal, if player places something in the lava for example diamond block, it will be gone.

@exotic obsidian it's working fine on me, as long as you assign the variable inside the task.

[exotic obsidian]

can u send the code please?

i want to see how? @summer scroll

[summer scroll]

    @EventHandler()
    private void onBucketEmpty(PlayerBucketEmptyEvent event) {
        if (event.getBucket() != Material.LAVA_BUCKET) return;
        // Start the task to remove the lava
        Executor.syncLater(60L, () -> {
            Block block = event.getBlockClicked().getRelative(event.getBlockFace());
            // If the block is lava, remove it
            if (block.getType() == Material.LAVA) {
                block.setType(Material.AIR);
            }
        });
    }

[exotic obsidian]

            new BukkitRunnable() {
                @Override
                public void run() {
                    org.bukkit.block.Block block = event.getBlockClicked().getRelative(event.getBlockFace());
                    if(block.getType() == Material.LAVA) {
                    block.setType(Material.AIR);
                    event.getPlayer().sendMessage("done!");
                    }
                }
            }.runTaskLater(Main.getInstance(), 15 * 20);

@summer scroll i think there's a joke xd

[summer scroll]

Yes like that.

[exotic obsidian]

i know but it is not works

[summer scroll]

Hmmm, not sure then.

[exotic obsidian]

wait i think i found the solution

[summer scroll]

What was it?

[exotic obsidian]

nah

i try to change the name of class because the name of class is the same as the block variable definition so i was thought there is confusing.

[summer scroll]

Bro what, don't tell me your class name is Block

I mean it should work regardless right? lmao

[exotic obsidian]

yup

i want u to try something

the code ur sended above is works with me

when i changed the timer

in the beginning was 15s right? i tried to put it 3

and it is works

but when u try number above 3 it is not works u can try

@summer scroll

[summer scroll]

I'll try 15 seconds.

[summer scroll]

Can confirm it works.

[exotic obsidian]

lol 😂

Np

Anyways thx for help me 🫡

[wet breach]

Make sure to help someone in the future

[summer scroll]

You're welcome!

Pls @ me In the response

[green prism]

Hi, I'm starting a petition to remove the debugging phase from the world. React with a + if you agree

[blazing ocean]

what debug phase

[green prism]

any software debugging work

just think about a world without debugs

[nova notch]

what are you on about

[twin venture]

gm , still have the problem 😶

..

[fervent void]

Using blockbench with spigot ??

[vast ledge]

You asking that ironically?

or you want to know if its possible?

[sleek estuary]

getstate instanceof Wool not works why?

instanceof wool returns false

[fervent void]

how do I use blockbench with spigot

[nova notch]

You use one of the existing plugins (model engine mainly) or make your own

Actually model engine I think only works on paper? Might wanna double check that

[blazing ocean]

why use model engine

[dense oracle]

hey, i want to disable the ender dragon spawn
i just canceled the CreatureSpawnEvent
however, the bossbar still apears
is there a way to remove it?

[blazing ocean]

you can just use custom model datas

[nova notch]

Well they didn't specify what "blockbench" is

For just simple item models yes

[sleek estuary]

how i verifiy if main thread is blocked?

[hazy parrot]

What

Why do you need that

[sleek estuary]

I have a method that goes through many locations and I feel that the server "crashes" at that moment, so I assume that the thread is being blocked

[short raptor]

If I've got config file with format

data:
  somekey: 1
  otherkey: 2
  thirdkey: 3

How can I get a list of those second level keys? e.g. a list of somekey, otherkey, thirdkey. I don't need their values

[sleek estuary]

this method runs through 10x10x256 locations

[hazy parrot]

getSection(data).getKeys(false) smth like that

[hazy parrot]

You can use spark or something

[short raptor]

Oh thanks, I was trying to use getStringList on data lol

[hazy parrot]

Or standard java profiling tools

[sleek estuary]

I don't know how to see in Spark if the thread is being blocked at that moment, but I'm sure it is blocking.

[hazy parrot]

You can send link here

[sleek estuary]

now im testing with for interaction

[blazing egret]

hi guys, I'm trying to make a plugin for guards but something went wrong and they don't attack entities, I'm attaching the code below
https://pastebin.com/2TFm7uzP

[sullen marlin]

What debugging have you tried

[blazing egret]

me?

[near mason]

use ModelEngine

and bedrock entity model

[sleek estuary]

if i do this and the server crashes a few seconds later, and auto-save was not called, this line of code will have no effect. correct?

[halcyon hemlock]

oink oink

meow

woof

[halcyon hemlock]

this shouldn't cause the server to crash lul

[twin venture]

this code to create custom potion effects does not work :

but the item is not changing still same ..

THIS IS HOW IT LOOKS LIKE :

no lore , no potions , no enchantments(for weapons , armors , tools) is working ..

[smoky anchor]

Idk how your code looks, I do not remember doing anything with potions myself
But the PotionMeta seems sus, you might be replacing the previously modified ItemMeta with it ?

[shadow night]

Are you ever applying the meta

[twin venture]

yes

the name is changed to &eSloth Potion so the item meta is set successfully

i have been trying for 2 day's now

idk what's wrong

this is how it should looks like

in the config file

any help will be appricated ❤️

potions , lore , enchantments and also the amount seems to not working?

only name and material do work

[smoky anchor]

I would recommend just creating some random command to test if you can create an item normally, as a sanity check of a kind ig

[twin venture]

thanks

[smoky anchor]

I would also check if you somehow modify the items in your list after creating them.
'cause I can't find anything wrong with your ItemCreator

[sleek estuary]

??

I did not say that

[halcyon hemlock]

you were asking, and I answered

;)

simple words: that piece of code should indeed not crash your server

[twin venture]

yeah me too

[11:23:17 INFO]: Potion Effect: SPEED Duration: 60 Amplifier: 2

[smoky anchor]

Try using that method to give a player those items isntead of whatever you're doing with them.

[twin venture]

it say that the potion effect is correct

oky

[smoky anchor]

That does not mean the item is correctly modified, that is just your debug.
You'd have to print the item instead.

To be sure the item is correctly created.

After the setItemMeta just print out the itemstack

[twin venture]

oky

to string

or only itemstack?

[smoky anchor]

Just itemstack is enough

I mean, the print method calls toString on its own if you pass an object.

[twin venture]

alr thanks

let me try

[smoky anchor]

Do keep me updated

[twin venture]

oh

it works

[smoky anchor]

So you're most likely modifying the items- what

[twin venture]

i don't think so

[smoky anchor]

You mean the whole thing works or.. ?

[twin venture]

it just not showing it here :

so when itry to remove it it open a menu

without lore , etc etc

when i give it to my self

it works

[smoky anchor]

Great, congratz on moving further with your problem :)

[twin venture]

thanks so much 🙂

brb gonna go eat now

[smoky anchor]

. . . how.. how does your createButton method work ?
I see it takes in the name and type............

For the next time just learn how to correctly debug.

[coarse trail]

hello, just wondering if anybody knows how to make java like chest ui, even tho bedrock users use pocket ui?
just like this.. ive been searching for a long time for this but seems like i cant find anything (edited)

[smoky anchor]

1. eww loot boxes
2. tell your users to switch the UI
3. I'll be surprised if I see you getting any support here

[echo basalt]

That is a slight pain in the ass

[smoky anchor]

Tho I have to say, I like the centered text there

[blazing ocean]

yeah that looks good

[coarse trail]

some recommended me use crossplatform but,, its only use bedrock forms thho,, but its not like to use/force classic ui,, cause bedrock pocket sometimes messes the plugins menus

[echo basalt]

the fuck is that supposed to mean

Bedrock forms are.. complex

You can, for example, use geyser's api to send a form, which is alright

But geyser only added API for like 10% of all functionality

[echo basalt]

If you want more than that you need to use Json-UI

And Json-UI is complex and not that many people know it

It does let you do things like these

[blazing ocean]

that can be easily done in java too

[coarse trail]

this form??

[echo basalt]

Yeah

[coarse trail]

i mean that form can be done to java too?

[echo basalt]

Java doesn't have forms

You'd need to have a regular menu on java and a custom form on bedrock

[coarse trail]

i guess i sould use cleshlike ui then on java while forms on bedrock

[echo basalt]

Up to you

[coarse trail]

i just want to be as possible not messing the plugin menu while i use bedrock tho,, the menus is inspired by this server
**95.216.228.73:25567 ** https://builtbybit.com/resources/premium-survival-setup-nitrosetups.27760/

even tho bedrock players use pocket,, the menu is still java-like chest ui

i wonder if it has any of the plugin but they said in the post the only use deluxemenu

[blazing ocean]

i mean on java p much everything is possible*

with resource packs

[echo basalt]

not everything though

bedrock allows for a lot more

but the scene is incredibly underdeveloped

[blazing ocean]

haven't played bedrock in ages

[queen idol]

why are buildtools creating a 1.20.1 jar when i select 1.20

[blazing ocean]

because it's practically the same

[young knoll]

1.20 was fully replaced

1.20.1 was like 2 bug fixes iirc

[queen idol]

i see, thanks

[orchid iron]

does anyone know how i can make a text display entity smaller and remove its background?

[young knoll]

Set the background color to something with 0 alpha

And use the scale part of the transformation

The provided connection is null

[blazing ocean]

?xy btw

cupboardarea have 25000 locations

[vast ledge]

epic command called ?paste

?paste

[undone axle]

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

[blazing ocean]

^

[vast ledge]

please use that

its easier than screenshots

[sleek estuary]

and it seems to be blocking the main thread because when I undo it, at that very moment the server "crashes" for a few milliseconds

[small hawk]

that what exception says ik, but im executing command as a player and as a player im surely connected to server

[sleek estuary]

500ms for the method to be executed

[blazing ocean]

runTask then?

[blazing ocean]

okay and that's not bad for 25k locations

[sleek estuary]

what would that do?

[sleek estuary]

db async ahah

[blazing ocean]

not run it on the main thread

[vast ledge]

youd have to check the nms mappings, to see what function returns what, and if the provided serverPlayer is not null

[sleek estuary]

location.getblock.settype is possible on secondary thread?

[blazing ocean]

what

[river oracle]

No

[blazing ocean]

not on an async thread

[river oracle]

You can't do any mutation asynchronously on another thread

[sleek estuary]

then how i make on async thread

for no "crashes" the main thread

[vast ledge]

changing anything in the world, usually cant be done async afaik

[sleek estuary]

you said to use bukkit.runtask

[blazing ocean]

ok?

[vast ledge]

that aint async

[blazing ocean]

that's not async

[river oracle]

https://www.spigotmc.org/threads/guide-on-workload-distribution-or-how-to-handle-heavy-splittable-tasks.409003/

bukkit#runAsyncTaskLater()

is async

or #runAsyncTask()

[blazing ocean]

what

?scheduling

[undone axle]

Stop going on about useless shit for world mutation

[sleek estuary]

Are you saying to make a scheduler that checks locations little by little?

[blazing ocean]

you didn't understand how tasks work

Can we just not ignore work distro thread please

then?

must've been the wind

[sleek estuary]

from what the topic title says, it says that it is using several threads to do this video

[river oracle]

It's literally not kekw

It's a single thread

Distributing it's task over time

[slender elbow]

async != multithreaded

🙃

[river oracle]

It's asyncrhonous still because the tasks don't occur at the same time

[slender elbow]

yes

[small hawk]

bump

[river oracle]

Nump

[slender elbow]

just pointing out that async != multithreaded because they seem to believe that is the case

[river oracle]

I was just intending to point out the differentiation on how you can have async without multiple threads

i know

we are on the same page

i am not dismissing what you said lol

[blazing ocean]

yeah? i don't get your problem

make it yourself then

or just add it

[blazing ocean]

🤷

should be

[sleek estuary]

I thought you knew about the current api

[blazing ocean]

and you can just impl that yourself easily

[sleek estuary]

BROOOOOOOOOO

[blazing ocean]

?

it's like 6 lines lol

[slender elbow]

you can literally just go to current bukkit source and copy the class

[sleek estuary]

HOW AM I GOING TO IMPL IF I DON'T EVEN KNOW WHAT THAT CODE DOES?

[blazing ocean]

yeah lmao

by reading the current code?

[sleek estuary]

I AM ASKING WHAT TO DO TO JUST IMPLEMENT MYSELF

[blazing ocean]

yeah i was just about to tell you

[slender elbow]

step 1 is to chill the fuck out

[sleek estuary]

HOW I READ THE MAX COORDINATES?

[sleek estuary]

I can't find it on Google

[blazing ocean]

just maxX = max(cornerA.getX(), cornerB.getX()) iirc

?stash

[undone axle]

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

[blazing ocean]

yeah and that for all 5 other ones

[sleek estuary]

OK

thx

[graceful patrol]

https://ibb.co/rmkhDZw
https://ibb.co/rdgd2Pr

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

[sleek estuary]

maybe be this

[blazing ocean]

please for the love of god don't inline those

[blazing ocean]

remove those includeGroup and run buildtools again

?mappings btw

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[blazing ocean]

?nms i meant

[undone axle]

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

[sleek estuary]

same thing

[blazing ocean]

it's just ugly

`Total Time: 4 minutes 43 seconds

Success! Everything completed successfully. Copying final .jar files now.
Copying spigot-1.20.1-R0.1-SNAPSHOT-bootstrap.jar to C:\Users\user\Downloads\spigot-1.20.1.jar

• Saved as .\spigot-1.20.1.jar`

its still the same tho (i opened intellij after it was comepleted)

[shadow night]

Replace the - in spigot-1.20.1 by a : in your buildscript

[graceful patrol]

so it should be compileOnly 'org.spigotmc:spigot:1.20.1:remapped-mojang'

?

[blazing ocean]

try

[shadow night]

Yeah exactly

the structure looks like this group-id:artifact-name:version:classifier

[graceful patrol]

still...

[torn shuttle]

does anyone know if the spigot way of serializing/deserializing data also saves pdc contents?

sorry I mean specifically for itemstacks

I was using base64 but people were asking me to switch

[shadow night]

How does it look now and do you have the remapped-mojang jar in your local maven repo

[buoyant sonnet]

how can i send my code for help

[shadow night]

?paste

[undone axle]

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

[eternal night]

it does (if you are talking about BukkitObjectOutputStream bs)

[torn shuttle]

so it should preserve all data like base64 does right

[graceful patrol]

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

[blazing ocean]

omg this is so fun

[eternal night]

well idk how you create the b64

[blazing ocean]

wrong channel

[torn shuttle]

I'm talking about itemstack.serialize and then itemstack.deserialize

[eternal night]

Well yea, but that method is used both for MemorySection#set and for BukkitObjectOuputStream

[buoyant sonnet]

https://paste.md-5.net/anepenitaw.java dont look add my comments

[torn shuttle]

alright I just needed to make sure it preserved everything because the whole point is to save items modified by other plugins so they're frequently loaded up with pdc data, thanks

[eternal night]

👍 (|| required disclaimer that bukkits item stack storage stuff is less than idea and is known to break on version upgrades|| )

[buoyant sonnet]

if i use any give cmnd but then i get in chat the command peinted

[young knoll]

Does our itemstack serialization include a version now

And run through DFU

[buoyant sonnet]

what

[graceful patrol]

i have this in my class:
import net.minecraft.server.IChatBaseComponent; import net.minecraft.server.PacketPlayOutChat;

why does it say "Cannot resolve symbol 'PacketPlayOutChat'"?

[blazing ocean]

?mappings

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[blazing ocean]

PacketPlayOutChat is spigot-mapped, but you have mojang mappings

[icy beacon]

isn't it 1.20.1-R0.1-SNAPSHOT

[tranquil glen]

hey guys, i was looking for some advice on some good practice

i have some location data that i want to story in a yml file, sort of like homes
should i load it into a map so it's in ram? or should i read directly from the file when i need to access it?

[young knoll]

YamlConfiguration already loads it into a map

But there's no reason not to have your own map as well

[tranquil glen]

okay, ill research YamlConfiguration

haven't really done much with serialization yet

good learning opportunity

[torn shuttle]

hm am I doing this wrong somehow? never tried to do it via spigot before (ignore the method names I'm in the middle of changing it)

    public static Map<String, Object> toBase64(ItemStack itemStack) throws IllegalStateException {
        return itemStack.serialize();
    }

    public static ItemStack itemStackArrayFromBase64(String data) {
        try {
            YamlConfiguration yaml = new YamlConfiguration();
            yaml.loadFromString(data);
            return yaml.getItemStack("");
        } catch (InvalidConfigurationException e) {
            throw new RuntimeException(e);
        }
    }

[16:35:13] [Server thread/WARN]: java.lang.RuntimeException: org.bukkit.configuration.InvalidConfigurationException: while parsing a flow mapping
[16:35:13] [Server thread/WARN]:  in 'reader', line 1, column 48:
[16:35:13] [Server thread/WARN]:      ... RON_CHESTPLATE, meta=ARMOR_META:{meta-type=ARMOR, lore=[{"text": ... 

definitely not happy

oh is it because it doesn't like the way it's a string? probably is isn't it

[spice burrow]

this is what i use

  public static ItemStack itemStackFromBase64(String data) throws IOException {
    try {
      ByteArrayInputStream inputStream = new ByteArrayInputStream(Base64Coder.decodeLines(data));
      BukkitObjectInputStream dataInput = new BukkitObjectInputStream(inputStream);
      return (ItemStack) dataInput.readObject();
    } catch (Exception e) {
      throw new IOException("unable to decode:", e);
    }
  }

[torn shuttle]

I'm switching out from base64 based on user feedback

I do have it working with base64

[spice burrow]

ahh

i read somewhere sometimes enchants dont deserialize properly but i havent had issues so far

[torn shuttle]

nah I definitely messed up forgot how I structured this in the backend, I should not be passing this as a string

oh hey think I got it

[languid hound]

what does that mean? : [Spigot Watchdog Thread/INFO]: Startup script './start.sh' does not exist! Stopping server.

[hybrid spoke]

i would assume, that the startup script './start.sh' does not exist and therefore the server has been stopped

[eternal night]

you presumably attempted to /restart

[languid hound]

how can i find out what the actual startup script is?

[open sage]

I would like to get the village Position from
/execute positioned 0 0 0 run locate structure #minecraft:village but that only returns the distance using store result.
Is there a way to get the raw console result so I can parse The nearest #minecraft:village (minecraft:village_plains) is at [24, ~, 24] (500 blocks away) using Bukkit code?
I'm using Bukkit.getServer().dispatchCommand(Bukkit.getServer().getConsoleSender(), to run the command.

[slender elbow]

use the api instead?

I can text it whenever i want

you stop provoking people

when did i do that lol

you just randomly do ?learnjava

hey, @echo basalt hoping you could share the link to me,, tutorial on how to make this

[hybrid spoke]

since when is it so long lol

[kindred valley]

is it funny

[blazing ocean]

no

[hybrid spoke]

it actually is yeah

[torn shuttle]

the first filter is whether people have the patience to read that whole thing

[blazing ocean]

it's really not long

[blazing ocean]

tiktok attention span go brr

[torn shuttle]

I often times can't get people to read 7 words

[blazing ocean]

i ain't reading allat

[eternal oxide]

Its way too long

should be a single link and a little text to a wiki page

[torn shuttle]

it should be a 5 second long tiktok video that shows a timelapse of learning java over 10,000 hours, sped up

I think this is what the matrix movie was about, it's been a whle since I've last seen it

[icy beacon]

5 seconds is too long

[hybrid spoke]

not if you add a subway surfer gameplay

[icy beacon]

still too long for my liking

[hybrid spoke]

damn you're in too deep

if you say so 😳

[kindred solar]

thx

[icy beacon]

it took me like 4 minutes to invert a condition of two booleans

very proud

[blazing ocean]

congrats

[shadow night]

Relatable

[icy beacon]

thanks

[coarse trail]

hi, wonder if you guys know how to connect old bedrock plpayers even tho geyser only support 1.20.80 now at the minimum

[grim hound]

how can I do Player#launchProjectile

without trigerring ProjectileLaunchEvent

[pseudo hazel]

why

[blazing ocean]

hashmaps ✨

[grim hound]

did

Why doesn't InventoryClickEvent fire on armor equip (by placing the armor piece)?

[inner mulch]

player inv is client side

[grim hound]

what

is

that

nonsense

[shadow night]

How tf would that work

[inner mulch]

your plugins are running on the server, if the server doesnt know about something (it happens client side) then there is nothing the server can do

[shadow night]

No, he is not asking about what client sided means or anything, he is asking you wtf you are sayinf

[inner mulch]

equiping armor is serverside but not the process of clicking it in the inv

[shadow night]

Only the creative inv is client-side iirc

[grim hound]

yes

[shadow night]

Everything else is handled on the server

[grim hound]

that's right

[shadow night]

Minecraft is a server bound game

[inner mulch]

wait i thought its client side

my mistake then

[grim hound]

maybe it's 1.20.1 spigot error then

[shadow night]

Any other plugins on ur server?

[exotic oracle]

is there a way to upload my own plugins?

[shadow night]

Wdym

[exotic oracle]

to spigot website

[shadow night]

Upload where

Ofc

[exotic oracle]

how

[shadow night]

Are you 7, 70 or why can you not navigate a basic forum site

By making an account and creating a resource

[exotic oracle]

i found it 💀

[ionic sapphire]

anyone an idea?

[grim hound]

how are you able to get the data but not the block?

since WallSign is a data type

not a block

right?

[ionic sapphire]

yeah, ik, when i'm using the normal Sign class it works for Oak Wall Signs, but not for other variants

[grim hound]

@sullen marlin explain yourself

[quiet ice]

jira is probably the better place

Though, what the the inheritance hierarchy differences between the classes?

[grim hound]

is there a way to apply a punch enchantment to a shot arrow?

i'm new to kotlin, any idea why?

[blazing ocean]

int is a primitive, which cannot be lateinit

set it to 0 or something

[sage patio]

Thonk

why getInt cannot be null but getString can

[kind hatch]

Cause primitives can’t be null.
Objects can.

[blazing ocean]

this is the whole kotlin string/java string thingy

[ionic sapphire]

okay... fixed it somehow, idk what the problem was 🤷‍♂️
anyway thx for the help 👍

[sage patio]

its nice but not yet xd

[tranquil glen]

anyone willing to help me debug something to do with my .yml file clearing upon server reload?

not sure how to fix it

[tardy delta]

getString()!! no null assert it

[blazing ocean]

[tardy delta]

what

[blazing ocean]

what if it's null

just ?: error("node is not found")

don't NPE it

that's bad for users

[tranquil glen]

Before reload, these test places are fine and are showing up okay

after reload, they're gone from the GUI, but not the yml

[kind hatch]

Reload or restart?

[tranquil glen]

and then after one more reload, they're gone from the yml

reload

[smoky anchor]

Sounds like you're not loading them

[kind hatch]

Probably a list being cleared.

[tranquil glen]

i'm loading them, but im not really sure where it's going wrong

i'll send my PlaceManager class

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

i run this every time on server startup

[inner mulch]

is there an event for finishing the game?

[blazing ocean]

as in end portal?

[inner mulch]

maybe that or just killing the enderdragon for the first time

this animation

idk

i guess just the entitydeathevent

[sullen belfry]

respawnevent triggers when you leave the end portal

[sullen belfry]

you can check the players stats and if the player has killed the ender dragon

on entityDeathEvent would work just check if the entity is the ender dragon

[inner mulch]

okay thanks

[sage patio]

?: null

kekw

[quaint mantle]

🗿

?: throw NullPointerException()

[sage patio]

yea jk

[blazing ocean]

[sage patio]

yes

what is your gpu? xd

[green prism]

xd

5700 radeon

amd

[sage patio]

ow, 6600

[green prism]

wanna split that 900 difference between the two GPUs? lmao

wait we're even using the same amount of ram

[sage patio]

lol

really?

yea almost

[green prism]

28.1 GB you

29.2 GB me

haha

[sage patio]

how tf you've 80gb of swap

Memory(swap)
71.9 GB/81 GB

is it because the size of partation? the server was on my desktop and my c drive has 128gb

maybe thats the reason

[green prism]

I don't really know haha, sounds very high

[grim hound]

does anyone know how I could download a newer java version on an aarch linux?

[blazing ocean]

yay -sS jdk

and archlinux-java ftw

[quiet ice]

looks good enough

[grim hound]

yay: command not found

[blazing ocean]

install yay kekw

at least have some basic arch knowledge first

[grim hound]

It's best learnt in practice

[blazing ocean]

?google

[undone axle]

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

[grim hound]

I

did

[blazing ocean]

then you'd have yay installed by now

[slender elbow]

pacman :nodders:

[blazing ocean]

some jdks aren't in arch repos

https://aur.archlinux.org/packages/jdk21-temurin

[grim hound]

uh

every command I try is just "command not found"

bruh

[blazing ocean]

what did you do

[grim hound]

I mean

nothing'

hehe

[grim hound]

no idea what any of this does

[carmine mica]

do uname -a

[blazing ocean]

dpkg ain't a thing on arch

and if pacman also isn't a thing that's not arch

[hazy parrot]

I mean u aren't using debian based distro lol

[grim hound]

Linux alixsystemtests 5.15.0-102.110.5.1.el8uek.aarch64 #2 SMP Sat Jun 10 18:23:55 PDT 2023 aarch64 aarch64 aarch64 GNU/Linux

[blazing ocean]

that's aarch

not archlinux

[grim hound]

uh

aight 👍

[blazing ocean]

you said archlinux

[grim hound]

kinda

so how do I install a newer java version?

[blazing ocean]

erm yea i missed that a

[slender elbow]

he literally said aarch

[grim hound]

since I need like 22

[blazing ocean]

im fucking blind ok

[slender elbow]

same

[blazing ocean]

what distro you running

[grim hound]

I'm pretty sure Debian

[slender elbow]

hello kitty linux

[grim hound]

once guy once showed me how to check that

[blazing ocean]

debian has dpkg

[grim hound]

but I forgot how

[blazing ocean]

cat /etc/os-release iirc

[grim hound]

oh no

it's worse

it's fedora

[blazing ocean]

oh no

fedora ain't that bad

[grim hound]

some people told me otherwise

[blazing ocean]

https://docs.fedoraproject.org/en-US/quick-docs/installing-java/

literally first google result

[grim hound]

I have no opinion since I have no idea about any of this

[blazing ocean]

oracle

[grim hound]

they did this

[blazing ocean]

i just read arch and my brain goes to neofetch and then turns off

[peak depot]

hey quick question what is the smartest move to disable a plugin when database com fails bc the rest of the plugin depends on it

[blazing ocean]

throw an error in initialiser

[chrome beacon]

Or just call the disable method in plugin manager and safely abort the startup of your plugin

[blazing ocean]

plugman vibes

[grim hound]

I did this sudo dnf install java-latest-openjdk.x86_64

but uh

65.0 bytecode versions are still unrecognized

[blazing ocean]

make sure to run it with the right version

[mellow edge]

^^^

[grim hound]

wdym?

I just start jars with -java

[blazing ocean]

do which java

[grim hound]

/usr/bin/java

[blazing ocean]

on arch they bins are located under /usr/lib/jvm/.../bin/java

idk how it's on fedora never used it

[blazing ocean]

and java -v?

[grim hound]

uhhhh

[blazing ocean]

-version ig

silly java

[grim hound]

bruh it's still 19

do I restart putty?

[blazing ocean]

does /usr/lib/jvm exist

[grim hound]

ye

[blazing ocean]

then use that

[mellow edge]

Are you trying to run a mc server but your new java version is not recognized by your server?

[blazing ocean]

sounds like it

[grim hound]

pretty much

[remote swallow]

use direct file path

[blazing ocean]

that's what i said

[mellow edge]

Why doesn't he just specify the path to the executable file (on win java.exe on linux I think just java) instead of java at the start

[eternal night]

use direct file path

[grim hound]

what does that mean?

[blazing ocean]

wait you might need to use direct file path!

[blazing ocean]

.

[remote swallow]

use the direct path to java.exe not just java

[eternal night]

java.exe fedora

[remote swallow]

java for linux nerds

[grim hound]

eeee

I am lost

[eternal night]

when you just type java -jar shit has to traverse your PATH to find a java binary on your machine

[grim hound]

why can't I just upgrade the jdk?

[eternal night]

if the first java binary found is the 19 one, you use the 19 one

[blazing ocean]

remove the old one

[eternal night]

to circumvent that, you just full specify the path to the java 21 binary

[blazing ocean]

i always prefer having everything installed or just docker

[grim hound]

which one

[blazing ocean]

dockerised mc >>

[blazing ocean]

the one you just installed

[grim hound]

ohh

but wasn't there a way to dynamically switch the used java version on linux?

[eternal night]

Well but changing around your path or by using symlinks

[blazing ocean]

idk on fedora

[eternal night]

but I am not well enough versed on fedora yea

[blazing ocean]

but arch has archlinux-java and debian has alternatives-list or something

[eternal night]

update-alternatives is debian iirc?

[blazing ocean]

ah yea that

[mellow edge]

I wonder what even defines default java on linux? Is it PATH or JAVA_HOME or something different?

[eternal night]

depends ™️

[blazing ocean]

path usually iirc

[eternal night]

some things might use JAVA_HOME

your default shell will just use PATH

[blazing ocean]

yea everybody just does their own shit

[river oracle]

U should just use sdkman on Linux

[eternal night]

[blazing ocean]

never heard of it

you should just use docker

[slender elbow]

sdkman on debian, sure

[mellow edge]

Docker best

[grim hound]

so just delete where it says 19

got it

[blazing ocean]

what no

[grim hound]

eh

then what?

[river oracle]

Not a big fan?

[blazing ocean]

use the direct file path as four people told you

[eternal night]

I mean, why use sdkman when you could be on an OS that has the AUR

[blazing ocean]

at least actually uninstall it, not just rm -rf the directories it uses

[grim hound]

but like

[river oracle]

I use Fedora. I don't like arch too much maitainence time for me

[grim hound]

to which java exe

[blazing ocean]

the one you installed

jdk 17

21*

[grim hound]

aight that works

thanks ;]

[quiet ice]

Are there some kind of HashMaps that supports weak values instead of weak references?

Can any people help with a plugin? im new to coding and i dont know how to fix this
"
@EventHandler
public void onPlayerDeath(PlayerDeathEvent event) {
Player player = event.getEntity();
for (ItemStack item : player.getInventory().getContents()) {
if (item != null && item.getItemMeta() != null && "Atlas Totem".equals(item.getItemMeta().getDisplayName())) {
int uses = totemUses.getOrDefault(player.getName(), 0) + 1;

            if (uses < 10) {
                event.setKeepInventory(true);
                event.setKeepLevel(true);
                totemUses.put(player.getName(), uses);
            } else {
                totemUses.remove(player.getName());

Error is?

[shadow pelican]

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

[shadow pelican]

yes

[vast ledge]

Thats not an error?

[shadow pelican]

weird

[vast ledge]

Whats the error, not is there a error

[shadow pelican]

i get setKeepLevel as a error

and onPlayerDeath

[vast ledge]

stacktrace?

[worthy yarrow]

go to your console and copy the big error that gets spit out

[shadow pelican]

?

[shadow pelican]

k

"cannot find symbol"

[vast ledge]

The entire error...

[worthy yarrow]

brother

[vast ledge]

sounds like the spigot jar isnt being included in the plugin tho

[shadow pelican]

im sorry im new

[worthy yarrow]

how would he compile then

[shadow pelican]

i khow how to do that

im not that stupid

[vast ledge]

No stack trace?

[worthy yarrow]

But you don't know how to copy/paste?

[vast ledge]

No error

just works?

Using the code provided

[shadow pelican]

ooo that cosole

[worthy yarrow]

...

[vast ledge]

....

[shadow pelican]

sorry

[vast ledge]

np

[shadow pelican]

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

That is the comoile

give me one min to start the server

[worthy yarrow]

I don't wanna do it, do you bedless?

[shadow pelican]

ooo k

[worthy yarrow]

It's a different thing

not to do with helping you

Rather a spigot inside joke if you will

[shadow pelican]

oo

ok

[vast ledge]

malformed pom?

[shadow pelican]

and wen i was compile it i got this "class AtlasItemsPlugin is public, should be declared in a file named AtlasItemsPlugin.java"

[vast ledge]

can you send a ss of your project struct and your main class?

[shadow pelican]

Ye'

[nova notch]

you can format it better like this

[quartz basalt]

World world = Bukkit.createWorld(new WorldCreator(String.valueOf(player.getUniqueId())).type(WorldType.FLAT));

after a server restart the world kinda dissapears, i cant access it anymore using /world <name of world>, any reason for this?

[vast ledge]

are you saving the world on shutdown?

[kindred solar]

I need help, java.lang.NoClassDefFoundError: net/minecraft/world/entity/player/Player using NMS

[quartz basalt]

no?

[sullen marlin]

You need to run that each time so the server knows to load it

[quartz basalt]

then im creating multiple worlds though no?

[sullen marlin]

Not if the name is the same

[vast ledge]

not if they got the same name

[quartz basalt]

also idk how that would work since i cant really store every players uuid, etc

[sullen marlin]

The method is really loadOrCreate

I doubt you want 10000 worlds loaded all the time

[quartz basalt]

i could probably just get all files in the container then ig and load like that

ok thanks

[sullen marlin]

How many worlds are you loading....

One for each player that's ever joined your server is a terrible idea

[quartz basalt]

im making a server where each player has their own island and their island is in their own world

[worthy yarrow]

That's just inefficient

[sullen marlin]

Load it when they join and unload it when they leave

You don't want every island ever loaded all the time

[quartz basalt]

yeah didnt rly think of that

[worthy yarrow]

Iirc the modern practice is same world different islands no? I mean rendering is already a thing so

[quartz basalt]

idk i looked it up and i found a couple pages saying 1 world for x islands is the same as 1 world per island

its also easier to do a world per player since the locations would be the same for every world

[worthy yarrow]

I mean you can just save any location for any player so that's not really valid argument imo

[quartz basalt]

🤷‍♂️ i find it a lot easier

[worthy yarrow]

It's not like that bad to world : player, but just do as md said and don't forget to unload the worlds when you dont need em anymore

[quartz basalt]

👍 ty fpr the help

[nova notch]

wouldnt ASWM be perfect for this?

[worthy yarrow]

Don't reinvent the wheel yeah, but good practice

[young knoll]

Or space them out in the same world

Depends what you really need

[worthy yarrow]

They don't want to do that

[young knoll]

Fair

It’s a bit more work to manage but you don’t have the overhead of loading and unloading worlds

[worthy yarrow]

Yeah and if the intent is to spawn them on their island onJoin, the loading worlds is a bit of a nogo

But ig their intent is unknown so up to them

[young knoll]

I still need to develop an algorithm for this tbh

I can create the world quickly, but I need to generate an area within the world without making the server cry

[sullen belfry]

anyone know how to fix this issue?

[vast ledge]

You're on a higher or lower java version than required

[vast ledge]

provided thing is on java 17

[worthy yarrow]

What makes the server cry?

[young knoll]

Trying to generate a lot of chunks at once

[sullen belfry]

how do i change it?

my pc has java 22

and i have java 22 selected in all my projects

[vast ledge]

you're trying to shade something thats on version 17

[vast ledge]

so im unsure

check ur pom.xml or build.gradle

[sullen belfry]

its bstats im trying to use

[vast ledge]

see what you're using in the shade

[worthy yarrow]

Why at once? You could try doing them in batches perhaps?

[astral glen]

hello, is there a guide for data pack developers to make them compatible with spigot?

[sacred mountain]

for recipes using RecipeChoice.ExactChoice / RecipeChoice.MaterialChoice

Will these be ONLY a single item, but multiple options
or will it be any variety of these items?

so like if i have a multiple choice that has Netherrack and Oak planks, i want to make it so i can only use ALL planks or ALL netherrack

[young knoll]

Well yeah, I just need to know when it’s done

[sacred mountain]

like not mix and match

[young knoll]

I was thinking about how to run a repeating task as a completable future

[acoustic shuttle]

    private void sendBlockDamage(Player player, Location blockLocation, int stage) {
        BlockPos blockPos = new BlockPos(blockLocation.getBlockX(), blockLocation.getBlockY(), blockLocation.getBlockZ());
        ClientboundBlockDestructionPacket packet = new  net.minecraft.network.protocol.game.ClientboundBlockDestructionPacket(player.getEntityId(), blockPos, stage);
        CraftPlayer cp = (CraftPlayer) player;
        ServerPlayer serverPlayer = cp.getHandle();
        ServerPlayerConnection playerConnection = serverPlayer.connection;
        playerConnection.send(packet);
    }```
(Yes I've tried the spigot method, yes I've tried protocol Lib, Yes it's sending these every tick)

No matter what I do the block break animation ends up looking extremely weird as show in the video it's like flashing on and off

[young knoll]

But then I realized I can use a callback instead

[worthy yarrow]

I wonder if you put completion thresholds in the generation process to moniter progress

[young knoll]

Use a different id, not the players

The api also allows you to do that

[worthy yarrow]

ie: checkpoints you could say

[young knoll]

Meh, I just need to execute something async when it’s done

[slender elbow]

I mean, that's basically what CF is :d

[worthy yarrow]

fair enough

[young knoll]

How would you make a future that returns when a repeating task has gone through X iterations tho

:p

[sullen belfry]

Bump

[slender elbow]

counter
if (counter-- == 0)
cancel();
future.complete(null)

[young knoll]

Omg right

I don’t need to use supplyAsync

[slender elbow]

yeah you can just create a new CF

[young knoll]

I’m special

I swear I’ve been using java for 10 years and not 10 days

[slender elbow]

I believe you :kek:

I've been fighting callbacks today

[acoustic shuttle]

Hm what should I just just a random int

Also why does it matter just curious?

[echo basalt]

Client-sided predictions

Just use the block's hashcode or something

[acoustic shuttle]

Alright ty

[young knoll]

Inb4 block hashcode matches player entity id :p

[echo basalt]

lil unlikely

Integer.MAX_LIMIT - block.hashcode just to be sure

[young knoll]

Could still match!

But yes it’s like a 1/4 billion chance

[acoustic shuttle]

@young knoll @echo basalt ty guys it worked

[carmine mica]

@lone jacinth can you explain what the point of the || condition is here? In what situation would the owner not be Material in an invokedynamic instruction's handle?

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/util/Commodore.java#335

[echo basalt]

arrays?

Not sure about exact bytecode but arrays are always wonky

[carmine mica]

an array won't be the owner of a values or ordinal call in an invokedynamic instruction. You can't call those methods on an array of materials, just methods on Object like toString

in both these cases, the owner should still be Material in the invokedynamic's handle

[echo basalt]

How about Material.values().length

or whatever

[carmine mica]

well .length isn't a method. You can't have an invokedynamic instruction with a H_GETFIELD from javac. you can have a H_GETFIELD in an invokedynamic in the jvm, but afaik, javac won't ever produce that. however, it shouldn't matter. All that matters is you return the correct array, then the .length is after that

the owner of the values() call is still Material

[echo basalt]

array.toString() mayhaps?

it's dumb but can happen

[carmine mica]

again, you already have the array

this is about getting the array, whatever happens after with the array is of no consequense

[inner mulch]

is there a way to fix the issue with maven, that even after install changes arent applied to other modules that depend on the other one?

[carmine mica]

this is rewriting the method to get the array

[echo basalt]

Is there some method to get an array that isn't like

values

[carmine mica]

I don't think so? That || condition didn't exist until it was rewritten to correctly handle invokedynamic and it's specifically checking stuff that is only present for invokedynamic

[young knoll]

getEnumConstants?

Wait no that’s on Class

[echo basalt]

maybe some fucked up plugin doing heavy bytecode shit caused some error

(^ is clueless)

can we like blame lombok or something

[carmine mica]

yeah, I'm curious as to what causes that. so I'm guessing derfrzocker has some reason why it was added

You can have this situation, but I don't think that covers this.

private static <E extends Enum<E>> int test(final E constant) {
    final java.util.function.Function<E, Integer> ordinal = Enum::ordinal;
    return ordinal.apply(constant);
}

test(Material.AIR);

so in this situation, the owner of ordinal is not Material, but Enum. But the instantated method type in the handle wouldn't include Material I don't think, so it wouldn't trip that second condition

I actually think that this example completely fails and could cause all sorts of issues currently since Material isn't known anywhere inside the test method. You'd have to rewrite all Enum::ordinal calls and check if the enum is a Material which is a huge performance drag

[sacred mountain]

for this, does that return a clone

or can i just use .add(material)

or will i have to take that list and update it and set it back to the pdc

manually

[carmine mica]

you have to set it back. pdc impls just wrap nbt

[sacred mountain]

alr

ty

[carmine mica]

so its creating the list every get() by parsing that nbt

[sacred mountain]

wdym

the get is only called on used interaction when the list is updated

thats all

[carmine mica]

yeah, and every time you call get it's re-creating the list from the nbt, and everytime you call set, it's taking that list and converting it to nbt

that list doesn't exist anywhere except when you call get, so it isn't even a clone

[sacred mountain]

oh i get what you mean now

I thought you were making a comment of the performance of it lol

yeah thanks tho

i get it now

[carmine mica]

well it could be performance comment if you were calling get 400 times instead of just once and then re-using the list instance

[sacred mountain]

lol

[inner mulch]

i have a multi module project, when i update the common module, it often happens that the new stuff still didnt arrive in the other modules after mvn installing the common one. is there a way to ensure this and not having to remove and readd common as a dependency?

[sacred mountain]

Unsupported class file major version 60

fudge

mfnalex's morepersistentdatatypes

im using java 22.0.1

how do i fix that lol

[snow pond]

had an issue with inventories, if u make a inv with Bukkit.createInventory it asks for title but how can this title be retrieved from the inventory object

[young knoll]

It can’t

It’s a bit weird, I know

[snow pond]

Is there some workaround

[sacred mountain]

create a neural net and a server side api that recognises english text, then port a monitor view from every client and read the inventory name

[lean ermine]

odd, in my listener, the event gets cancelled but swapdye seemingly does not work, but this only happens on high ping, why would this be?

public void onItemClick(PlayerInteractEvent event) {
        Player player = event.getPlayer();

        ItemStack itemInHand = player.getInventory().getItemInMainHand();
        if (itemInHand.getType() == Material.LIME_DYE || itemInHand.getType() == Material.GRAY_DYE) {
            if(event.getAction() != Action.PHYSICAL && (player.hasPermission("hubbly.playervisibility.use") || player.isOp())) {
                event.setCancelled(true);
                swapDye(player, itemInHand);
            } else {
                player.sendMessage(ChatColor.translateAlternateColorCodes('&', config.getString("messages.no_permission_use")));
            }
        }
    }

private void swapDye(Player player, ItemStack itemInHand) {
        Material newMaterial;
        String displayName;
        if (itemInHand.getType() == Material.LIME_DYE) {
            newMaterial = Material.GRAY_DYE;
            displayName = ChatColor.translateAlternateColorCodes('&', "&rPlayers: &cHidden&r");
            for(Player online : Bukkit.getOnlinePlayers()){
                player.hidePlayer(plugin, online);
            }
        } else {
            newMaterial = Material.LIME_DYE;
            displayName = ChatColor.translateAlternateColorCodes('&', "&rPlayers: &aVisible&r");
            for(Player online : Bukkit.getOnlinePlayers()){
                player.showPlayer(plugin, online);
            }
        }
        ItemStack newItem = new ItemStack(newMaterial);
        ItemMeta meta = newItem.getItemMeta();
        if (meta != null) {
            meta.setDisplayName(displayName);
            newItem.setItemMeta(meta);
        }
        player.getInventory().setItemInMainHand(newItem);
    }
