[wet breach]

states can have their own textures is what it comes down to

[upper hazel]

As I understand it, you need to change its state to the desired one during placement so that the texture of the block changes?

[wet breach]

states are like changes, and with changes means a way to convey that visually. Not all states are visually represented

therefore you can make use of them, even more so when there is unused states to be used 🙂

[upper hazel]

hm this cool i gess

but I guess the states are strictly limited

spawnerBlock with an entity, is it just a block or also an entity?

I heard ItemAdder uses them

for textures

[wet breach]

its a block

but also an item if its in the eventory

[grim hound]

So

AsyncPreLoginEvent

Can have more than one thread invoking it?

[wet breach]

you mean listening to it?

or you mean when its thrown?

its async because netty threads you know

[grim hound]

So it's invoked from the netty threads?

[grim hound]

what?

[eternal night]

yes

the event is called from a network thread not the games main thread

hence your logic in your listeners for AsyncPreLoginEvent is invoked on the respective network thread too

[grim hound]

I just asked whether it was one or many threads

[eternal night]

implementation detail

for most server implementations, multiple threads are used tho

you can block the pre login event just fine if that is what you are asking

other players should be able to connect just fine

[wet breach]

it depends on how many netty threads there are, by default there is 4

so you can in theory have that event fire at the same time 4 times

but its one of the few events as lynx said that actually happens outside of the game loop

[grim hound]

I'm asking whether I'm working in a multi-threaded environment

[eternal night]

Given that there is a main game thread and at least one netty thread, yes

[grim hound]

I already got the answer

[eternal night]

perfect

[grim hound]

Thank you

Btw

Is a thread equal to another in terms of computational power?

[eternal night]

"yes"

[grim hound]

If I recall correctly they aren't only if comparing user to virtual threads

[eternal night]

virtual threads aren't really a thing in the JVM yet, iirc they are still in preview ?

oh wait no

they were finalised in 21

[grim hound]

What

Wait

Then how come

A server have like 52 java threads

With only having like 16 physical ones

[eternal night]

what

platform threads can exceed the core count ?

its just that the OS scheduler deals with them

instead of the JVM itself (which is the case for virtual threads)

[grim hound]

I really don't know whether you're asking or being annoyed

[eternal night]

(not that plain java threads are typical OS threads, more of a JVM implementation detail as to what it ends up being)

[lost matrix]

The OS has a scheduling strategy which lets the pyhsical threads work on any OS threads + the OS itself.
Sometimes this means the physical thread actually jumps between two os threads every few micros/nanos for just
one or two instructions (At least in real time operating systems). Each windows, linux and mac have different strategies.

But you could in theory start 100 threads in java which are all handled by a single physical core if your OS and/or jvm impl suck.

[glossy venture]

the reason its still advantagious to create multiple threads in that case is because of blocking operations which halt the thread meaning it isnt scheduled so other threads have more resources to do their work

[slender elbow]

no it isn't

[eternal night]

gasps

[slender elbow]

with all the plugins you have doing blocking IO in that event that would massively increase the ping of 1/n of your player base lol

n being the number of Netty threads

[eternal night]

I mean it isn't run on a netty thread...

The auth threads are still network threads

stop the flame

[slender elbow]

the server thread is also a network thread if I perform network ops on it

[eternal night]

There you go

[slender elbow]

:yesyes:

[eternal night]

now you think correctly

phew

auth threads are just network threads to the mojang services

[grim hound]

But wouldn't jumping so often between threads be strictly inefficient?

[rotund ravine]

[slender elbow]

your thread not running because something else is is also surprisingly inefficient

it wildly depends on the kernel every how many cycles it switches processes

and what strategy etc

even for Linux they seem to use a new scheduler every few versions lmao

[eternal night]

something has to support my e-cores

[storm crystal]

how can I use interact entities?

[eternal oxide]

interact entities?

[young knoll]

What do you want to use them for

[spare hazel]

how can i detect armor breaking?

or any tools

[rotund ravine]

There is an event iirc

[spare hazel]

found it

[storm crystal]

I want to know how to spawn them, move them, read what entities are inside of them, remove them

[young knoll]

You spawn, move, and remove them just like any other entity

As for reading what's inside them, you can use entity.getBoundingBox with world.getNearbyEntities

[storm crystal]

what type of data is bounding box?

[young knoll]

BoundingBox

[storm crystal]

yeah but how do I extract entities inside that bounding box?

[storm crystal]

but that gets nearby entities in world

https://cdn.discordapp.com/emojis/1137506523761885264.webp?size=48&name=Weirdge&quality=lossless

[young knoll]

Yes

[eternal night]

it has a BoundingBox overload

[young knoll]

And one of the options you can pass to it is a bounding box

[eternal night]

so it gets the "nearby entities in the world" that are insidethe bounding box

[storm crystal]

whats that?

[eternal night]

hm ?

are you asking what an overload is ?

[storm crystal]

yes

[eternal night]

Method overloading in java is a feature that allows a class to have more than one method with the same name, but with different parameters.

[storm crystal]

first time im hearing it

[summer scroll]

Is it possible to get others minecraft server data like player count maybe? For example I know a server with ip play.minecraft.net and I wanted to get the player count of that server, is that possible?

[rotund ravine]

Yeah

[eternal night]

there should be a couple of libs out there that do pings for you

[rotund ravine]

https://wiki.vg/Query

[summer scroll]

Alright, I think I can use this right? https://mcstatus.io/

[rotund ravine]

Probably?

[young knoll]

All you need to do is send a query packet to the server and read the response

Could make a quick api for that ig, But I assume one exists already

[slender elbow]

yeah I mean there's a million

(I counted them all/

it's a fun quick project

[young knoll]

Ah then I could be 1,000,001

How exciting

[summer scroll]

I could just use PlaceholderAPI Pinger placeholders smh.

Thanks for the help anyway guys!

[upper hazel]

i try find note block texture but i have just 1 texture

but how i undestand note block has 800+ textures

[grim hound]

Is there a way to change max players at runtime?

[eternal oxide]

in your resource pack. you add them

every change to teh NotBlock Meta makes it a different block, as far as your resource pack knows

[upper hazel]

if so, then logically they should not add up

[eternal oxide]

They are still just Noteblocks

look at teh resource pack I linked you

[upper hazel]

were

[eternal oxide]

if you place a noteblock and change it's values you geta different texture

[upper hazel]

but when you change the itemStack it stops stacking with the main itemStack and if noteBlock works like that it shouldn’t stack when dropped

[eternal oxide]

you change when you place

[young knoll]

Wait I have a sample

[upper hazel]

does this mean there will be 800+ note Blocks in the inventory?

[young knoll]

no

There is always only 1 item for a given block

[upper hazel]

i mean if you click and break block

you will have 1 state

[young knoll]

Here's a sample noteblock file for a resource pack

[upper hazel]

2 state

3

e t c

[young knoll]

Any state will drop the same item when broken

By default anyway

[upper hazel]

ah i see now

default drop?

[young knoll]

what?

[upper hazel]

I'm confused when you put a block it doesn't store information inside itself. And that means the drop will be normal standrard item

[eternal oxide]

when you break a block you get back it's default block

[upper hazel]

yea

[eternal oxide]

no matter if you changed it when placing

[upper hazel]

I forgot that the block does not store information (

[young knoll]

I mean, the states are the information in this case

[upper hazel]

although it would be great if this was added

[shadow night]

What if BlockBreakEvent -> if brokenBlock.getMetadata()... -> blockItem.getItemStack()...

[young knoll]

You could but metadata isn't persistent

There is block PDC, but in this case you can just use the states to identify the block

[shadow night]

I know command blocks can store nbt while in the inventory

[rotund ravine]

?customdata

I know there was some util using the chunk pdc

[shadow night]

?blockpdc

[undone axle]

Learn about CustomBlockData here:
https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[shadow night]

That one?

[rotund ravine]

Probably idk

[upper hazel]

By the way, persistentDataContainer is not persistent, right? This means that the data from the chunk pdc must be stored somewhere

[eternal night]

persistentDataContainer is not persistent, right?

[shadow night]

It literally says persistent

How much of what did you smoke

[upper hazel]

ah yes i bad speak eng 👍

didn't read the literal translation

[young knoll]

Idk why you don't just use the state as a unique identifier

[upper hazel]

the library from that link about customBlock must store data somewhere, but how does it do this if the data is not constant

[rotund ravine]

It is

[young knoll]

It stores it in chunk pdc

[shadow night]

PDC (Persistent Data Container) is persistent, it just stores stuff in the chunk pdc, as chunks, worlds, entities (including block/tile entities) and items can have pdc

[rotund ravine]

It stores it as nbt data

[upper hazel]

oh

so is "persistent" ahh

I'm already confused about these translators

[shadow night]

Metadata = not persistent
Pdc = persistent

[rotund ravine]

Pdc = persistant data container

Persistent*

[shadow night]

Yes

The only case where storing stuff in metadata is acceptable is when you don't need it to persist

[young knoll]

As long as you clean it up

Otherwise yay memory leaks

[grim hound]

Wha-

[rotund ravine]

He’s nonnative it seems

[upper hazel]

i not eng

[grim hound]

I under stand

[upper hazel]

how much here eng?

[shadow night]

Do you mean much

[upper hazel]

yes

[rotund ravine]

I am not english, but i did have english at high levels in school

[shadow night]

I am not english, but I accidentally learnt it once

[rotund ravine]

Happens to the best of us

English is a plague

[shadow night]

Worse than french?

[rotund ravine]

French is also a plague

[valid burrow]

agreed

[valid burrow]

cant agree with that

english is so easy

[rotund ravine]

Still a plague

[storm crystal]

bro literally wants to go back to latin apparently

[slender elbow]

erm 🤓 old German, actually, not Latin

[hushed spindle]

i smelled drugs

whats going on here

[rotund ravine]

Drugs are good for you

When doctors prescribe them properly

[blazing ocean]

hiya, im currently using this code:

        fun createFakePlayer(name: String, displayName: Component, uuid: UUID): Player? {

[river oracle]

is there any way to specifically disallow comments passing a certain character limit in IntelliJ, currently I hard wrap at 120 characters for code, but I want it to be shorter for comments

[slate tinsel]

Hi, if I want to teleport a player to the nearest safe place within maybe 9x9 blocks and if that example is slabs, stairs, etc. then the player should be teleported to the nearest place correctly how can I do it?

[lost matrix]

You need to pass an EnumSet of wrapped actions and a List of wrapped entries

[slate tinsel]

So example that the player is teleported correctly when slab like this

[blazing ocean]

ok so packet.playerInfoAction.write(0, EnumSet.of(EnumWrappers.PlayerInfoAction.ADD_PLAYER)) doesn't work because it needs an int and a EnumWrappers.PlayerInfoAction

[blazing ocean]

@lost matrix

[lost matrix]

    PacketContainer packet = new PacketContainer(PacketType.Play.Server.PLAYER_INFO);

    Set<EnumWrappers.PlayerInfoAction> actions = EnumSet.of(
        EnumWrappers.PlayerInfoAction.ADD_PLAYER,
        EnumWrappers.PlayerInfoAction.UPDATE_GAME_MODE,
        EnumWrappers.PlayerInfoAction.UPDATE_LATENCY,
        EnumWrappers.PlayerInfoAction.UPDATE_DISPLAY_NAME
    );

    packet.getPlayerInfoActions().write(0, actions);

    // You got this part already
    WrappedGameProfile profile = new WrappedGameProfile(UUID.randomUUID(), "Bob");

    List<PlayerInfoData> playerInfoDataList = List.of(
        new PlayerInfoData(profile, 0, EnumWrappers.NativeGameMode.SURVIVAL, null)
    );
    
    packet.getPlayerInfoDataLists().write(0, playerInfoDataList);

[blazing ocean]

ill try

[blazing ocean]

still the same error

error occurs in this line: packet.playerInfoDataLists.write(0, playerInfoDataList)

[lost matrix]

Which plib version?

[blazing ocean]

v5.1.0

[lost matrix]

Server version?

[blazing ocean]

1.20.1

[lost matrix]

Weird

Try writing the actions first and check if its throws an exception

[blazing ocean]

so not writing the playerinfo?

[lost matrix]

Write the info after writing the actions

[vital vortex]

please someone go on #help-server sorry but i really need

[blazing ocean]

somebody delete that

[blazing ocean]

thats what I've been doing

[lost matrix]

Show which line exactly throws the exception again pls

[blazing ocean]

.

[lost matrix]

Yeah no idea why it doesnt work for you then...

[blazing ocean]

this is so frustrating

hi, has anyone here already configured Plan Analytics on an https domain name with nginx?

If you want to save a string on an item you can use pdc

how i can optimize it?

[glad prawn]

cache your romanSymbols 🤓

and the one below it too 🤓

[compact haven]

(by cache he means make it a constant)

[heavy mural]

My display entity seems to remove it's render before the chunk that it is positioned on is out of render distance. View range (from display entity) and simulation distance (from server properties) and Entity-tracking-range (from spigot.yml) all seem to not fix the issue.

Is there any other setting I am missing?

[stone cosmos]

Oh did not know that, thought it would use packets so it could track stuff off the main thread, that explains the higher performance costs of it compared to others.

[rustic hamlet]

is anyone here familiar with bungeecord messaging because for some reason mine stopped working after migrating my server

[drifting viper]

Hello, Ye Sparten does Use More Resources than other Anti-Cheats and Can't detect as much as others

I even think they didn't fixed the 3+ block vanilla Step yet

[stone cosmos]

Yeah, I know, I had, well not the best experience with it, I switched to smth else already, but it's still surprising me that he does not use packets.

?

[drifting viper]

No, The Spartan Developer already wrote a message in this Chat explaining that he was Very Young as he created Spartan and gained alot of experience over the years, Still recoding Spartan to an Packet Based Anti-Cheat is too much work for him and consumes too much time he don't has

[rustic hamlet]

yea

is anyone here familiar with bungeecord messaging because for some reason mine stopped working after migrating my server

[stone cosmos]

Didn't he publish a speech that indicates that this was his main source of income for many years and is now even selling 2.0 based on a Patreon sub? Well sounds like BS to me.

[drifting viper]

I actaully don't know, I think Minecraft Anti-Cheats can be very profitable because there are not Many Good Solutions but a high demand, Many Server Owners don't know what they should do

[drifting viper]

migrating from what to what ?

[rustic hamlet]

wait i might be onto the solution

stand by

[rustic hamlet]

i just set up my dedicated server slightly differently on the backend

now for some reason bungee messages not getting through

[stone cosmos]

That's what I mean, sounds like a BS excuse of why it can't be rewritten.

[drifting viper]

mhh, Maybe a Networking issue

[valid burrow]

there are so little because they are simply INCREDIBLY difficult to make

[rustic hamlet]

I think it might have to do with the ip's of the server changing or something

[valid burrow]

i mean not even servers like hypixel have a working one

3 year old clients still bypass it

[drifting viper]

Its not that hard, You just need to have good Ideas and than its easy

Im working on a own Anti-Cheat but don't have really time for that :C

[shadow night]

That's not how shit works

[valid burrow]

if its not that hard do it xd

if you manage to make a good one

you will make hella bank

good luck man

[drifting viper]

mhh thanks, Your welcome to try make an Anti-Cheat too: https://gist.github.com/Snowiiii/2c306f3e8926bc7fb8acaaa8c3c105d7

[grand flint]

what event runs when u middle click a block in creative

[young knoll]

InventoryCreativeEvent

[grand flint]

thx

it returns the block clicked too right?

with its properties?

[severe hinge]

did you fix that?

[warped shell]

any ideas on how to minimize tps drops from hoppers/tileentities?

[valid burrow]

paper

[warped shell]

ye i alr have it

lol

[valid burrow]

not much more you can do i believe

[warped shell]

ye thats why im asking around

i dont know anything else

ty though

[valid burrow]

most servers jusr limit hoppers peer player

or redstone in general

[warped shell]

well id rather not have to do that but I see the point

I alr added a tile entity limit for like 1k per chunk

its a last resort for somone actually trying to lag the server

but some farms need hoppers

[valid burrow]

well then the only thing you can do is

upgrade server

maybe

[warped shell]

ye i plan on it really soon

[valid burrow]

use the block feature ad soon as it drops below 15tps

[warped shell]

ye

i alr completely stopped entity spawning

below 15 tps

[valid burrow]

mhm

good

could also lower chunk loading

[warped shell]

ye i also made entities no spawn in new chunks for 30 seconds

that really helped

[rotund ravine]

Isn’t there a tick limiter for hoppers

[warped shell]

hm

maybe i could just stop all hoppers

below 15 tps

[rotund ravine]

Also. Don’t crosspost in 4 places wtf

[warped shell]

lmao

no one answers in paper somtimes

[valid burrow]

believe me nothing is worse then the luckperms disclrd

[warped shell]

lol

[valid burrow]

my server with 60 members answers faster

[rotund ravine]

I am gonna block every single person who crossposts from now on

[warped shell]

lmao

ig im blocked

for asking a question

rip

[dry hazel]

reasonable

[warped shell]

fr

[blazing ocean]

nope. ..

[storm crystal]

if I want to spawn Interaction entity in x,y,z location and set it to be 1x1x2 rectangle, would it's length be equally distributed in that center?

or would it count the length from a corner like that?

[eternal oxide]

Entities spawn by corners

[storm crystal]

alright

how can I change their dimensions?

[eternal oxide]

read teh javadocs https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Interaction.html

[storm crystal]

oh okay I forgot to cast Interaction

thats why I didnt see it

[young knoll]

Shouldn't have to cast if you use the fancy spawn method

[river oracle]

fancy spawn method ftw

Does someone maybe have an idea on why this is not working?

[eternal oxide]

Missing/outdated NBTapi

[quaint mantle]

hi is there a way to set a specific line of a text display

i have a lot of characters to put into a text display but if i do it all at once the client disconnects

[mental crystal]

it is in my build path. I tried v 2.12.1 and v 2.10.0 (which has worked a year ago)

[rotund ravine]

Add the plugin to plugins

https://www.spigotmc.org/resources/nbt-api.7939/

[storm crystal]

what kind of problem is that?

first time im seeing it

[chrome beacon]

You casted Interaction to LivingEntity

Which won't work since Interaction isn't a LivingEntity

[storm crystal]

but im getting interaction

[chrome beacon]

Not all entities are living entities

[storm crystal]

okay I get it

how can I make armorstand's rotation same as player's?

[eternal oxide]

setDirection

[mental crystal]

Thanks this worked :)

[river oracle]

How big can a minecraft world be? I'm kinda of curious right now if its plausible to use an Int2Object map in my situation by instead of having a 1d array with 3 entries I could pack all of the coordinates together using bit shifting and use that as the map key otherwise I'll prob just go with the array

[tall dragon]

isnt it pretty much unlimited?

as far as your hardware takes you i guess

[river oracle]

well I've heard its around 30,000,000 in practically as there is a world border there

[tall dragon]

yea

[rotund ravine]

Pretty fucking big

[tall dragon]

there does seem to be one at 30m blocks

but it can be removed

if one would like that

i see no reason the world coulnt be bigger than that

[rotund ravine]

Oh u difn’t mean size?

[river oracle]

is there still glitches and stuff where you can't place blocks and stuff after that, I remember there always being weird quirks with removing it

mainly need to know as I'm making a plugin that relies on world coordinates for keeping track of certain structures and this is a super rare edge case, but I gotta know

[rotund ravine]

I think it can be infinite

But past a certain point it becomes broken

[tall dragon]

yea

[river oracle]

I wonder is it realistic to do a Long2ObjectMap than use bit shifting to shift the 3 ints together still?

[quaint mantle]

is there a way?

[river oracle]

do multiple text displays then maybe?

[quaint mantle]

yes i can

but ill have over 300 textdisplays

[river oracle]

time to replan I think then

[storm crystal]

how can I check if a certain entity UUID is already stored in this ArrayList?

[tall dragon]

#containsKey

[slender elbow]

i mean, they're cheap af

[quaint mantle]

yes but i went from 300 to 10 fps after a few

server was running 20 tps

[storm crystal]

like that?

[tall dragon]

yea

that will return either true or false if it contains it as key

[quaint mantle]

playerHitEnemies.get(uuid) != null

:)

[storm crystal]

its not what I wanted

I want to see if it has THAT particular entity UUID in here

[tall dragon]

i mean, if you are going to end up getting that list. its the same

else, contains is fine

[quaint mantle]

https://wiki.vg/Entity_metadata#Text_Display it does appear to be one thing

[storm crystal]

problem is that entity is added to ArrayList despite me saying in code that if it's been added it shouldnt be added 2nd time

[hazy parrot]

computeIfAbsent is redudant here

[young knoll]

You are checking if the map has the entity as a key

Not the list

Also, you could use a set to avoid duplicates

[storm crystal]

I was told to use it like that

[hazy parrot]

oh ig its probably not same uuid

mb

[storm crystal]

first value is player UUID

second value is ArrayList of entitiy UUIDs

I want to check if ArrayList of that specific player contains that entity UUID already

but idk how to work in nested lists

[hazy parrot]

map.get(playerUUID).contains(entityUUID)

as coll suggested you probably want to use Set there

instead of list

[storm crystal]

why

[pseudo hazel]

since there is no point in having duplicates

and if you arent gonna have duplicates, sets are the way to go

[fiery blade]

Hello, is there any way to spawn a lightning and not affect the player who spawned it (I explain?), I have a code that spawns a lightning and affects nearby entities in a limit, but I have already tried several alternatives and still doing damage, the code is as follows:

player.getWorld().strikeLightning(player.getTargetBlock(null, 100).getLocation());

                    int radius = Main.getInstance().skills.getInt("lightning.radius");
                    double damage = Main.getInstance().skills.getDouble("lightning.damage");

                    player.getWorld().getNearbyEntities(player.getLocation(), radius, radius, radius)
                            .stream()
                            .forEach(entity -> {
                                        if (entity instanceof Player && entity != player) {
                                            ChatUtil.console("PLAYER DAMAGED BY A LIGHTNING: " + ((Player) entity).getName());
                                            ((Player) entity).damage(damage);
                                            ((Player) entity).addPotionEffect(new PotionEffect(PotionEffectType.SLOW, 200, 2));
                                        }

                                    }
                            );

[young knoll]

strikeLightningEffect

[storm crystal]

so Set cant store duplicates by default?

[hazy parrot]

No duplicates, plus contains is much faster on Set then on ArrayList

[orchid trout]

bro plzzz help my es ku el no work'
myeskuel

[pseudo hazel]

ur what

[river oracle]

mysql

[orchid trout]

my es ku el

[river oracle]

don 't ask how tf I figured that out

just say MySQL bro

[storm crystal]

I wouldnt need to use contains tbh

if I had a set

[river oracle]

dont' try to confuse the people helping you kinda idiotic

[storm crystal]

cuz no duplicates

[pseudo hazel]

?

yeah true

you just put it in

thats the whole point of a set

[orchid trout]

i want interate potgrekuql

[storm crystal]

???xd

[pseudo hazel]

they are talking to crackma im pretty sure

[fiery blade]

thank u bro

[storm crystal]

wait how do I add one Entity UUID to Set in to this kind of Map

[pseudo hazel]

playerHitEntities.get(playerUUID).insert(uuid)

or add I mean

[dry hazel]

well you need to computeIfAbsent it, since there won't be a set entry for that uuid

[rotund ravine]

Why do you use a concurrenthashmap

[pseudo hazel]

yeah to insert a set for a player you mean

[river oracle]

was about to ask this

since Entities can't really be accessed via asynchronous threads

[storm crystal]

idk it was like that in another code

xdddddddddddd

[river oracle]

please know the data structures you are using

[tall dragon]

do u know what they are for

[storm crystal]

it works sooo

https://cdn.discordapp.com/emojis/1100415648665980998.webp?size=48&name=Clueless&quality=lossless

[river oracle]

but it works worse for your case

[pseudo hazel]

then they just need a better server 🤷

[storm crystal]

how do I compute if absent with list

[pseudo hazel]

its a map

you dont have a list?

[storm crystal]

uh its map<uuid, set<uuid>>

so how do I compute if absent it

[pseudo hazel]

yeah

[storm crystal]

with set

yeah not list, set

[pseudo hazel]

wdym

[hazy parrot]

same as u did with list ?

[dry hazel]

literally the same thing but with a set implementation

i.e. HashSet

[storm crystal]

like its -> with ArrayList

[pseudo hazel]

wait so why do you need computeifabsent

[storm crystal]

someone told me I need it

lol

[pseudo hazel]

thats not a good enough reason to add it

[storm crystal]

.

[pseudo hazel]

I dont even know how you want to add stuff to your sets

[storm crystal]

thats what I am literally asking about

[pseudo hazel]

yeah they were talking about when you dont have a player id in the map yet

[storm crystal]

yeah and I dont have them

[pseudo hazel]

okay then use computeIfAbsent on the map

not on the set

[storm crystal]

eh

its like that for ArrayList

how is it for Set

how to do it for Set

its what I am asking for

not how to computeifabsent for set

[dry hazel]

dude please learn basic java data structures

HashSet instead of ArrayList

[pseudo hazel]

or a concurrentHasSet if you like those 😛

[stone cosmos]

What is this master piece of a lambda abusive ArrayList with one entry in a map if absent?

Just curios

[storm crystal]

???

[orchid gazelle]

For resource pack dev, how tf do I center my model in blockbench so that the arrow is accurately on the position I want it to be?

[pseudo hazel]

what arrow

[orchid gazelle]

I use displayentities to simulate projectiles

when spawning it without resourcepack, it's centered on the vector where I want it to be

when I use the resourcepack, the model is off in position

[pseudo hazel]

oh, idk sorry

[storm crystal]

well I was told to do it like that

so I just did it

https://cdn.discordapp.com/emojis/1100436689836585010.webp?size=48&name=Shrug&quality=lossless

[orchid gazelle]

no worries^^

[stone cosmos]

I just saw that snipped and where wondering what you try to code with that piece of art? Just my curiosity.

[pseudo hazel]

a plugin probably

[hazy parrot]

yeah i would also assume they are making a plugin

[storm crystal]

well judging by your tone you are rather looking to mock someone so im not going to answer that

[grim hound]

I hope you realize what this code does, right?

It ain't wrong if you're sure that's how it should be done

[storm crystal]

it makes playerUUID and adds this EntityUUID to list

[stone cosmos]

Fine, Fine, you are right.
But what ever that is, rather create a common class to hold the data structure than running multiple maps what use UUIDs, it's just redundant.

[storm crystal]

and then just adds them if PlayerUUID exists

I guess

it works like that at least

[grim hound]

Yeah it creates, places and returns an ArrayList

But the creation only takes places for when it's absent

[pseudo hazel]

which makes sense

[grim hound]

Otherwise it just returns the existing list

[grim hound]

Yes

[storm crystal]

yeah

thats literally

what I need

[grim hound]

But you understand why that works, right?

[pseudo hazel]

but yeah I do agree with sirbro that it would be beter to create a class for a player that has these sets and stuff rather than creating a bunch of maps

how many of these maps do you have

[storm crystal]

why when doing abilityStand.getLocation().setDirection(player.getLocation().getDirection()); armorstands are always on one specific direction?

even when I switch my looking direction

[pseudo hazel]

well what does getDirection return

[grim hound]

That is not how

[storm crystal]

direction?

[grim hound]

Locations work

They just return a separate object/a snapshot

Of the entity's position

ArmorStand#teleport

[eternal oxide]

player location holds teh bodys location/facing

[grim hound]

Is how you actually modify it

So do

[eternal oxide]

player getEyeLocation returns the head location/facing

[pseudo hazel]

right, I just had to look it up to make sure xD

[grim hound]

Location loc = armorStand.loc

loc.setDir(player.dir)

ArmorStand#teleport(loc)

[eternal oxide]

yep use teleport

setDirection will only adjust teh Location object which is a clone

[grim hound]

Location is always a snapshot that does not change the original holder's location

[storm crystal]

cant I just

abilityStand.teleport(abilityStand.getLocation());

[grim hound]

No

Because as I'm saying

[storm crystal]

why?

[pseudo hazel]

you cna but nothing changes xD

[storm crystal]

its literally same thing

[grim hound]

.

[eternal oxide]

its not the same

[grim hound]

getLocation always returns a

new Location

[eternal oxide]

armorstand.getLocation returns a clone, so modifying it will not affect teh stand

[grim hound]

It's not.

[grim hound]

All locations do that

[eternal oxide]

getLocation, setDirection, then teleport the stand to the modified location

[grim hound]

Anyways I'm going to sleep

Gn

[storm crystal]

so stupid

[pseudo hazel]

🤷

[pseudo hazel]

yeah

3 is too many to repeat

[stone cosmos]

Cloning is not stupid, is necessary in an API, since Java passes by reference except of primitives, you would end up in hell, passing references via API.

[pseudo hazel]

when you have repeated something like 3+ times, its time to approach it differently

[storm crystal]

why?

it works

[pseudo hazel]

its annoying and the code gets bloated

sure it works

[storm crystal]

annoying for who exactly

[chrome beacon]

you

[storm crystal]

I dont feel annoyed

[pseudo hazel]

tahts because you dont know any better

[storm crystal]

what do you suggest then, if you know better

[stone cosmos]

Because 3x map or list lookups, resizes etc. operations will consume a lot more time/load than just creating one class object what holds the data structure in a single map or list, as I said

But what do I know

[storm crystal]

and what, it would sit in that class and it would do exactly same stuff

so whats the difference

[pseudo hazel]

you only have to get your "player" object once

[stone cosmos]

The difference is, that one list or map holding the data class's object is more performant than x lists or maps just holding a part of it and also cleaner code.

[pseudo hazel]

because it would just be a List<PlayerLists> for a lack of a better name

which also means it will scale better when you decide to add more maps

[tough parcel]

how can you use a config.yml file to change different attributes of a gui (rows, lore, items, etc.)

i'm new to java its quite confusing

[pseudo hazel]

well those are 2 seperate things

[storm crystal]

so like what

I can just make

[pseudo hazel]

first one being how don you read from a config file

and the second part being how do I change attributes of a gui

by which I assume you mean some way to create a gui from a config file

[storm crystal]

List<playerUUID, ListOfLists<List1, List2, List3...>>?

[pseudo hazel]

yes essentially

[tough parcel]

fuck

wrong person

anyway

[storm crystal]

I just want it to store spawned Armor Stands, Interactions (that I use as hitboxes) and Enemies standing in those Interactions

ArmorStands for animation purposes

Interactions for mechanics

which works like that rn

and it just works fine

anyone thats in it gets damage as long as they are living entity and not armorstand

[pseudo hazel]

if those are the only 3 lists youll ever need its probably fine

[pseudo hazel]

whats teh confusing part

[storm crystal]

idk if those are the only 3

like

I want to make those 3 by each ability separately

so that they wouldnt get mashed together

[tough parcel]

?

oh

[pseudo hazel]

you said its confusing

[tough parcel]

nvm i think ill find some way

sooner or later

[storm crystal]

like 3 lists for this ability, 3 for that etc.

[tough parcel]

thank you for volunteering ig

[storm crystal]

so that I wouldnt remove armorstands / interactions / use hit enemies by something else by accident

[pseudo hazel]

I would reccomend to start out creating a menu hardcoding it into a class

[stone cosmos]

Just forget what I wrote, your experience with Java is not nearly big enough yet, would just mess up your code atm. just keep your lists, no offense.

[pseudo hazel]

and then devise some kind of format that would work for creating a menu on the fly

[storm crystal]

I already made several manager classes

lol

I just wanted to see how to use interactions properly

I didnt think that Id need 3 separate lists

so I should make a class that would create, remove and edit such playeruuid nested lists?

[lament slate]

I am trying to figure out how to make it so that everyone in a server says a random number from 0-9 or gets messaged a random number either or I am confused though how I would do that would I make a for loop and grab all the players then for each player it goes through the loop? Im still newish to coding so sorry if its a easy solution - I did the random number generator already

[grim hound]

Bukkit.getOnlinePlayers().forEach(p -> p.sendMessage("random: " + new Random().nextInt(10)));

[lament slate]

Thanks

[grim hound]

Just make a variable for that Random

[quaint mantle]

    var friendlyByteBuf = new PacketDataSerializer(Unpooled.buffer());

    friendlyByteBuf.c(id);
    friendlyByteBuf.writeDouble(loc.getX());
    friendlyByteBuf.writeDouble(loc.getY());
    friendlyByteBuf.writeDouble(loc.getZ());
    friendlyByteBuf.writeFloat(loc.getYaw());
    friendlyByteBuf.writeFloat(loc.getPitch());

    var EntityTeleport = new PacketPlayOutEntityTeleport(friendlyByteBuf);
    // send packet

am i missing something obvious?

https://wiki.vg/Protocol#Teleport_Entity

https://mappings.cephx.dev/1.20.2/net/minecraft/network/protocol/game/ClientboundTeleportEntityPacket.html

https://mappings.cephx.dev/1.20.2/net/minecraft/network/FriendlyByteBuf.html

[dry hazel]

I mean, look at how the constructor reads the bytebuf

[storm crystal]

wait so what should I use instead of this CocurrentHashMap?

[dry hazel]

HashMap lol

[smoky oak]

I got a really weird copyright question. I've made a plugin for someone else, and their co-hoster fuckin stole it lol
https://github.com/Thatundeadperson/ReachSMP
can i
a) tell github to take it down, and will it happen?
b) get him for copyright violation?
he also posted it on spigot.
https://www.spigotmc.org/resources/reach.113507/
@worldly ingot can you take that down, please?
side note it is on my private github if needed for evidence

[storm crystal]

whats the difference in them

[dry hazel]

CHM can work in concurrent environments

with a slight overhead

i.e. you can use it from multiple threads at a time

[stone cosmos]

A concurrent hash map has build in locking mechanics so it can be used async (multi threaded), you will not need that using the regular Bukkit/Spigot api.

[quaint mantle]

how?

[storm crystal]

im not using any apis tho

[quiet ice]

CMH is also useful if you modify it while iterating

[dry hazel]

decompile the packet class

[dry hazel]

you are inherently using the spigot api

[stone cosmos]

If you modify while iterating, create an Iterator, do not abuse a concurrent hashmap.

[quiet ice]

Wha?

[quaint mantle]

i don't even know how to acces it

[quiet ice]

How do you iterate without an iterator?

[floral drum]

I love ReentrantLock's!

[quiet ice]

Meh, CHM does not use those

[dry hazel]

CHM doesn't actually lock a lot, if at all

[lament slate]

Quesiton do I have to make that a seperate class since I keep getting the error can't resolve symbol bukkit if I do not NEVERMIND import spelt wrong

[quiet ice]

Well CHM does lock quite often actually but these locks are not worth speaking about

[stone cosmos]

For, forech, stream, whatever is available for the given data type, not talking of what it is using internally.

[quiet ice]

And they are only required for resizing bucks and stuff

[lament slate]

Nevermind my import was spelt wrong

[smoky oak]

@vagrant stratus can you take this down?

[quiet ice]

for - iterator
foreach - iterator
stream - iterator but fancy
iterator - iterator

[river oracle]

be patient

[smoky oak]

eh fair

guess im used to replying instantly myself

[floral drum]

Yeah they just use synchronized blocks

[lethal coral]

how can I send an empty resource pack to the player so it unloads the previous one?

[smoky oak]

le shrug

[quiet ice]

Even my relatively lock-free ConcurrentInt62Set uses locks: https://github.com/Starloader-project/stianloader-concurrent/blob/main/src/main/java/org/stianloader/concurrent/ConcurrentInt62Set.java#L88-L100.
But I never really found a use for reentrant locks in Data structures

[storm crystal]

some people have priorities

https://cdn.discordapp.com/emojis/1100436689836585010.webp?size=48&name=Shrug&quality=lossless

[smoky oak]

for me the green point means 'repliy ready'

guess people dont use it like that

[quiet ice]

For me it generally me "My PC is turned on - if it isn't a thursday it is likely that I will respond soon"

[smoky oak]

thats what the yellow is for tho?

[quiet ice]

Well uh, I don't bother manually setting that flag

[dry hazel]

just set it always to away

[quiet ice]

I have a few people that I know personally that have set their status to always be offline

[stone cosmos]

Well, whatever it uses internally, you will need to access the iterators methods to perform operations safely while iterating, otherwise ConcurrentModificationException and than of course you could also use a concurrent map what might not be necessary by using the first approach, but it most likely does not matter.

[quiet ice]

Which is just pain for me since I cannot really be "well, at this point you probably read it"

[cursive falcon]

what packet lib should I use for 1.20+, since protocollib doesnt support 1.20+

[quiet ice]

The whole point of CHM is that CMEs are impossible

Almost no concurrent datastructures will throw CMEs

[lament slate]

is there a way to make a player run a command like sudo or do you just grab there name and make the server run a command for them?

[quiet ice]

That is the point of using them

[stone cosmos]

Why would you care if single thread and clean code, but ok

[mental crystal]

Uhh sory stupid question, i cannot remember what programm to use to access a storage from my hosted server. i got the ip, port, username and password.

[hazy parrot]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#performCommand(java.lang.String) its useful to look at docs

[lament slate]

Ok ill look at them rn

performCommand
thanks your a lifesaver!

[hazy parrot]

depends on what service you want to access lol

[quiet ice]

Because you just won't bother? It's less to worry about, has a much smaller fuck-up risk and less lines of code for basically the same performance outside of hot code

[mental crystal]

the storage where backups and all the minecraft server files lay

[storm crystal]

what approach should I take if I want to make GUI that would display unlock progress for a player based on what level (not in-game experience level, but just some arbitrary made level mechanic) they practically achieved?

[hazy parrot]

you are probablly refering to FTP service, hence i like FileZilla for it

[quiet ice]

Also, modification while iterating can sometimes be a little more than plain removal of objects - for example what if you need to add or replace objects?

[mental crystal]

AHH yes filezilla was it yesss thanks lol. Just randomly forgot the name of it

[quiet ice]

Isn't that illegal is many countries?

[lament slate]

Question for performCommand - Does the player need to have perms to perform the command or will the server force them to perform it

[stone cosmos]

Yeah, fine, I admit it might has it's advantages

[smoky oak]

he in north carolina

single state consent

only matters to who is recording it

i know american law well enough to know hes in the clear

[quiet ice]

So yes, it is illegal.

[hazy parrot]

i assume they still need permission

[quiet ice]

Probably not considered blackmail, so not completely bad but still.

[lament slate]

Ya same thats going to be hard to figure out

[smoky oak]

fair

[lament slate]

Ill just maybe make the server run the command then and target the player then

[quiet ice]

I think we misunderstood each other. Whatever

I was referring that extortion might not be completely fine, which they did by offering a ransom payment

[smoky oak]

welll

he took the source code and published it

[quiet ice]

Yeah that blatant act I disregard

[smoky oak]

and now hes like 'pay me to take it down'

[slender elbow]

I would think that "the whole point" is thread safety and atomicity 🤔 but sure

[shell trench]

How can I detect when an item is added to the players inventory?
(I know there is a InventoryPickupItemEvent, but this only works for item pick ups, not for item changes if obtained from a chest or /give)

[young knoll]

You’d have to check every tick

There is no event that covers all changes to an inventory

[lament slate]

I just downloaded the plugin lombok for intellij and after trying to import it to the project I was previously workong on I get cannt resolve symbol lombok

[rotund ravine]

What build system do you use

[lament slate]

Windows 11

[rotund ravine]

Maven, gradle etc.

[lament slate]

Maven sorry

[rotund ravine]

Did you setup the compiler plugin in there properly?

[lament slate]

I am pretty sure give me a minute

All I know is that I have Kotlin and Lumbok which is all I thought I needed to download to use it

Do i need t o set something up or get sometihng else?

Wait I know what I did wrong

I didnt put it in my pom file

[green plaza]

How to set items in the loom?

[ivory depot]

What is the best way to mysql? In plugins

[river oracle]

The same with other inventories

[green plaza]

No its not like that

[wet perch]

Can someone help me with plugin messaging?

Is this right? https://pastebin.com/igMEMAux

[river oracle]

Yes it is? If not you'll need to explain more about what you're doing

[wet perch]

I want to use my custom channel for this

[green plaza]

I am trying to set item to the loom. Loom is full client side and you can not just use setItem to set item

[river oracle]

loom is not full client side

[green plaza]

Yea

Then please

Provide me a code

When you use setitem

[river oracle]

try InventoryView#setItem

[green plaza]

W8

[river oracle]

I'm currently working on a PR for bukkit based soley around Inventories and InventoryView's I have been testing it quite frequently and such behavior has been identified as both possible and executable by a plugin

I can assure you, with 100% confidence, the loom inventory is not fully client sided and it is possible to set Items within it

[green plaza]

How InventoryView?

        Inventory battleInventory = Bukkit.createInventory(null, InventoryType.LOOM);
        battleInventory.setItem(0, currentBanner);
        battleInventory.setItem(1, dye);

        return battleInventory;

[river oracle]

createInventory does not work as intended

you can't use that method

[green plaza]

What should i use?

@river oracle

[river oracle]

you'll need to use NMS until my PR is merged

[river oracle]

if you're using paper api paper has a HumanEntity#openLoom method iirc

[green plaza]

Create LOOM INVENTORY in nms?

[river oracle]

kind of yeah

[green plaza]

Spigot

[lament slate]

I am having troubles adding project lombok to my pom file(Maven) I can not just copy and paste it because of "multiple root tags" anyone know why

[river oracle]

then NMS will be required here

[green plaza]

How to create it XD?

[river oracle]

are you using mojang mappings

[green plaza]

No i am not using mappings

Should I?

[river oracle]

?nms

[undone axle]

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

[river oracle]

yes mappings are absolutely necessary now adays

obfuscated makes this process much harder

[green plaza]

I am used to NMS but i have been using mappings but i have not been coding plugins for a long period of time XD

[river oracle]

just lmk when you have mapping set up

[green plaza]

👍

[river oracle]

okay this might be a second to type out

[green plaza]

I need to use BuildTools

Cuz i do not habe 1.17 mappings

[river oracle]

yeah we have a GUI if you would prefer to use that

#1117702470139904020 message

[green plaza]

What's the diffrence

[river oracle]

its just a GUI vs command line only

[green plaza]

Nah i'll use the full version

[golden lava]

World#rayTraceEntities does not include Displays?

[lament slate]

I have been trying to add Lombok to my project however even after installing the plugins and trying to copy and paste the new pom lines to maven it does not work does anyone know if I am missing a step?

[river oracle]

Player player; // we assume we have a player
CraftPlayer craftPlayer = (CraftPlayer) player;
// Convert to NMS player
ServerPlayer nmsPlayer = craftPlayer.getHandle();
int nextCounter = nmsPlayer.nextContainerCounter(); // this is an ID that can be sent to the client so it knows what is going on
final ContainerLoom loomContianer = MenuType.LOOM.create(nextCounter, nmsPlayer.getInventory()); // this creates our loom
// Bukkit handles a lot of the work for us so our job here is pretty much done
// This gives an InventoryView! remember this can only be created by the player you made that NMS container with, otherwise errors will occur.
InventoryView view = loomContainer.getBukktitView();
// now we can do edits if we want
Inventory inventory = view.getInventory();
inventory.setItem(0, new ItemStack(Material.BLUE_BANNER));
// now we can finally open the view
player.openInventory(view);

@green plaza hopefully this explains everything if you have errrors lmk

[green plaza]

Thx ❤️

I have question but its related to java

Why you use final?

[river oracle]

uhm its a small compiler optimization that will usually just get done automatically I just do it out of habit

you really don't need to use it in this case

[compact haven]

sheeshers, ik this is completely unrelated but heyo- first time I've seen you outside of sku

doing alright lime? been a while

[green plaza]

Ik i don't have to but i am just curious why ppl do that

Also heard few times that it boost performance a little bit

[river oracle]

final just means you aren't going to reassign it, I do it for clarity

[river oracle]

yeah, but the compiler automatically does it, when coding its not really something you need to be cognisent of

[golden lava]

I don't come here. I'm just here to complain that Spigot forgot to include Displays in rayTraceEntities.

[green plaza]

But JDK has to use more bit's to mark that's it's final soo how is that boosting performance XD?

[compact haven]

lmao, u sure it's not counted? I'd think it'd count anything that's an entity

[golden lava]

// Paper Method
result = origin.rayTraceEntities(targetBlockDistance, ignoreBlocks)

// Tried Spigot too, always null.
result = origin.getWorld().rayTraceEntities(origin.getEyeLocation(), location.getDirection(), targetBlockDistance, 0.0D, entity -> !entity.equals(origin));

Works fine for a single pixel of an armour stand 120 blocks away. Not a block display right in front of me.

[river oracle]

dont' know a lot about jvm so who knows

[floral drum]

honestly people mainly use it for immutability purposes and cleanliness

[green plaza]

I have a question

[compact haven]

@golden lava check if the Display entity is revealed with World#getNearbyEntities
(checking source rn and it seems that ray trace also uses that method)

[green plaza]

    private void getLoomInventory(Player player, ItemStack dye) {
        CraftPlayer craftPlayer = (CraftPlayer) player;
// Convert to NMS player
        ServerPlayer nmsPlayer = craftPlayer.getHandle();
        int nextCounter = nmsPlayer.nextContainerCounter(); // this is an ID that can be sent to the client so it knows what is going on
        final LoomMenu loomContianer = MenuType.LOOM.create(nextCounter, nmsPlayer.getInventory()); // this creates our loom
// Bukkit handles a lot of the work for us so our job here is pretty much done
// This gives an InventoryView! remember this can only be created by the player you made that NMS container with, otherwise errors will occur.
        InventoryView view = loomContianer.getBukkitView();
// now we can do edits if we want
        Inventory inventory = view.getInventory();
        inventory.setItem(0, currentBanner);
        inventory.setItem(1, dye);
// now we can finally open the view
        player.openInventory(view);

    }

Inventory inventory = view.getInventory(); -> here it pokes me for int for method getInventory

Does it matter for loom?

[river oracle]

oh yeah use getTopInventory

my bhad

[green plaza]

If that works i'll suck your toes

[river oracle]

please don't 💀

[green plaza]

Haha

[river oracle]

Unless 1.17 changes something that 1.19.4 has with inventories it'll work and that prospect scares me

[green plaza]

I don't think so. Packet implementations are quiet the same

[green plaza]

Please tell me how to create component

So i can set this gui a title

[river oracle]

oh yeah the title lol

[river oracle]

do you want a custom name

or just the normal one

[green plaza]

Custom name

new TextCompoentn("text"); Will work?

[river oracle]

don't think so

gimme a second

[green plaza]

Okok

[river oracle]

CraftChatMessage#fromStringOrNull

[green plaza]

Lol it did

XD

[river oracle]

this is why we need Inventory PR

[green plaza]

What is inventory pr?

[river oracle]

my pr to add all of this to api <3

[green plaza]

It's just implementation for spigot/paper?

Or will have implementation from scratch

[young knoll]

@golden lava display entities have a hitbox size of 0, so the ray can’t hit them

HOWEVER you can use the double argument of the method to increase the size of all hitboxes so you can hit them

[river oracle]

it adds API to bukkit, and implementation to craftbukkit

[compact haven]

this makes a lot of sense honestly

[golden lava]

Ok, so then why does this default to 0.0D https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/CraftWorld.java#871

[compact haven]

why shouldn't it? Why would it arbitrarily expand hitboxes unless you're attempting to do something special?

[river oracle]

so e.g. it would look like this within the API subject to change

Player player;
LoomView loom = MenuType.LOOM.create(player, "The Title");
player.openInventory(loom);

[young knoll]

Because by default it shouldn’t expand hitboxes?

[golden lava]

But then it's not including Displays, an Entity.

[young knoll]

Yeah well displays are special and have that 0 size hitbox

Mojang basically wanted them to be excluded from ray traces so they don’t block anything

[golden lava]

I would like to recommend changing that default or including that to the JavaDoc of the method.

[compact haven]

definitely don't change the default, but it should be logged in the JavaDoc ngl

[young knoll]

Yeah that can be done

Remind me tomorrow or make choco do it :p

[compact haven]

will remind u tomorrow at this time

[young knoll]

Ideally someone can make a jira issue for it

[river oracle]

fr ^

[young knoll]

Gotta be official and all

:p

[compact haven]

well im definitely not doing that xd

[young knoll]

This is why we can’t have nice things

[river oracle]

cuz coll messes everything up

[green plaza]

@river oracle i have custom InventoryHolder, any chance to implement this to this loom?

This Holder just holds every click event's etc and don't want to implement it manually

[river oracle]

ahhh Holder's shouldn't be used like that let me send you a better way to do it

https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

[river oracle]

pretty sure you'd need to use patches to get holders to work anyways

e.g. forking spigot

[green plaza]

I am using it as it is being shown here

Something similar to this

But more complicated

[river oracle]

as long as you're not using actual InventoryHolder's you can kind of cheat here lol its gonna be hacky though since you can't do patches

just get the Inventory from the InventoryView and store it

[storm crystal]

should I make manager class for custom GUIs made with inventories?

or can I get away with making each by hand?

[young knoll]

Some kind of manager is usually good

[floral drum]

Using a class which inherits InventoryHolder is good too :)

[storm crystal]

like making an inventory with X rows filled with certain items as background and custom name set and then changing separate objects by hand based on what I'd want?

[storm crystal]

whats that?

[green plaza]

Then one more question cuz i am lazy asf. What event is being trigered when player complete loom crafting?

[river oracle]

No clue

[young knoll]

Do not use inventory holder to identify inventories

The end

[wet breach]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/CraftItemEvent.html

[young knoll]

Yeah idk if that’s fired

But you can try it

[storm crystal]

I want to make some kind of interactable skill tree / stat upgrade tree within GUI for each player

[green plaza]

Nope as always InventoryClick wave his hand

[storm crystal]

so that it could fill inventory items with visual representation based on readings from player's config

like if he's got that upgrade or not etc.

[sick ermine]

I am coding an invitation system, the sent invitation should be deleted after a while. Should I use Bukkit Scheduler or BukkitExecutor or something else?

[young knoll]

Use a scheduler along with timestamps

Store a timestamp for when the invite should expire a check them every once in a while using a repeating task

[sick ermine]

Will I check all invitations at the same time in the scheduler? But this may cause some invitations not to be deleted in time.

[young knoll]

Why would they not be deleted in time

[sick ermine]

Will I define a specific scheduler for each object?

[young knoll]

Nah you can just use one to check them all

[sick ermine]

In this case, invitations that do not disappear at the right time appear.

[wet breach]

if you are using mysql it can do this for you btw

CREATE EVENT clearExpired
ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 2 MINUTES
DO
   UPDATE table SET status=0
    WHERE status <> 0
      AND TIMESTAMPDIFF(SECONDS, NOW(),table.timestamp)>120;

/* OR */

CREATE EVENT clearExpired
ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 2 MINUTES
DO
   DELETE FROM table
    WHERE TIMESTAMPDIFF(SECONDS, NOW(),table.timestamp)>120;

mysql has events that are handy to use 🙂

expiring rows/columns are one of those things

so let mysql clean them up for you instead of wasting resources 😛

[river oracle]

oh wow this is fucking neat

[sick ermine]

I offer mysql and sqlite support to the user. There is also the possibility of using sqlite. Also, I do not plan to write the invitations to the database, I can keep them in memory, it is not important data, they can be lost when the server is shut down.

[wet breach]

well, options 😉

[young knoll]

?

[sick ermine]

For example, a scheduler ran every 5 minutes and then an invitation was created that had to be deleted after 1 minute. This invitation will be deleted the next time the scheduler runs, that is, after 5 minutes.

[wet breach]

glad someone might find it useful 😛

[storm crystal]

Is it a good idea to store custom experience points and levels like combat experience from hypixel in player configs?

Or should I think of other way?

[hazy parrot]

So make it check every 10 or 20 seconds

[river oracle]

sounds like you should use a database!

[drowsy helm]

Use a db

[wet breach]

also in case you don't need permanent storage, mysql does have memory only DB's

[river oracle]

don't worry there are plenty of choices, MongoDB, SQLIte, MySQL, Postgress!!!!
(You should probably just use SQLite)

[wet breach]

so lets say someone wants to use mysql like you said you offer support for, the plugin could run more optimally by not having to store such info in memory when the DB server can do that for them

[lament slate]

i want to make a code for each player online assign them a random number than message them that number any ideas on the for each player online since thats where I am struggling

[wet breach]

as well as handle expiring stuff

and then just have your code do the whole in memory scheduling if sqlite is being used since SQLite is just binary file storage

[storm crystal]

Im pretty sure I was told to keep using configs

So when do I use config and when database

[wet breach]

only because in terms of ease the API already provides you stuff, where as using a DB you need to create your own methods and the sorts to do this, aside from the fact you are stubborn in learning java stuff 😛

[storm crystal]

You literally advised me to not take half measurements and you did sell me half measurement

Which means that majority of my work goes to scrap

[wet breach]

I didn't sell you a half measure o.O

[storm crystal]

What can possibly happen if I use config for that

[wet breach]

you can use a config if you want, but yaml starts to bog down once you start hitting like a few hundred to thousand config options, and if you want to use a yaml like structure still you option would be to move to just storing pure json instead and then from there you would have no choice but to move to binary storage if what you are storing keeps getting larger, and then from binary storage you would need to look at a proper DB server. But DB servers like mysql don't take up much resources so sometimes it might just be best to start with a DB to begin with if you expect to be storing a lot of data and more so if that data needs to persist or is needed elsehwere.

[young knoll]

Yeah just check more often

Comparing time stamps is a cheap operation

[lament slate]

Question I am wondering how would I give everyone a random number then do something with that random number? Would I need a array For Example, 1 = diamonds 2 = dirt and every player gets a 1 or 2

[wet breach]

well why not 0 and 1?

then you could use a boolean if you wanted

Java has api methods for using Random with a range as well

so your range would just be 2

and you would check if the random number provided is either a 0 or a 1 🙂

[lament slate]

I know how to use random with range its just how would every player get there numer and ther eitem

Just check if all the players have 0 or 1 with a statement and give them the items?

[storm crystal]

So in that case how do I make database

And how do I read it

[wet breach]

depends which data base flavor you want

[storm crystal]

?

[wet breach]

most of the time comes down to preference

[storm crystal]

I dont have a preference

[wet breach]

Well just like programming languages, there is different kinds of DB's

[storm crystal]

Idk something that works?

[wet breach]

well they all work of course

[storm crystal]

All my work is now for shit so ill have to start from zero

[wet breach]

however, some have limits while others are tailored to more specific things

[storm crystal]

I want something to store custom enemies, weapons, playerstats etc.

[wet breach]

well this is part of learning and overall part of development sometimes. Not everything works out perfectly in one go

sometimes you learn what you were doing is just not good enough

[storm crystal]

For which you told me to use configs for

[wet breach]

so you just start again

[wet breach]

I don't recall me being the one specifically for you to use configs, just that you are not willing to learn

since you don't want to learn proper stuff, easier to just direct you to something already provided

continuing with not learning proper stuff, using a DB isn't going to make that better and you will in fact make things worse potentially as using DB's are not as forgiving as the API is

[storm crystal]

I dont consider that kind of attitude, namely "heres a half measurement now fuck off" on a help channel apropiate

[wet breach]

well you are not paying

so you have no right to say anything about it

[storm crystal]

It doesnt work that way

[wet breach]

the support most receive here as well as the educating would typically cost you a hefty penny for, but we freely do it and we are not paid either nor does anyone pay for this support

[storm crystal]

Since when money determines how important your opinion on a matter is

[lament slate]

would this assign everyone a random number if so there seems to be a error Bukkit.getOnlinePlayers().forEach(new Random().nextInt(10);

[wet breach]

Well, we are not obligated to provide support nor do you have a right to it either. We have no obligations to really do much of anything, but we still provide support because we want to. You are free to not like it, but we are free to not like those wanting support as well. It is a two way street type deal. You refuse consistently to not learn appropriate basics, methods, and conventions to the point it makes it difficult to provide you support on stuff you ask about because you lack the understanding required.

[wet breach]

well this sets your range to 10

0-10

[lament slate]

Yes it does however would it give everyone a number or no?

[wet breach]

well 0-9 actually

[lament slate]

true

[wet breach]

possibly, but I probably wouldn't use new random for everyone though

[lament slate]

I am a new coder sorry I am struggling with this XD

[wet breach]

I would create 1 random object, and just call nextInt() every time

and then assign a number it provides

[lament slate]

wait so create a integer then make it generate a random number then do 1 player then continue?

[wet breach]

calling new Random() if you have a large enough players would actually lag your server since its a taxing process to generate randoms 😛

[lament slate]

its going to be like 5-10 players

[storm crystal]

And in the end makes you look very unprofessional if you resort to giving poor quality answers

[wet breach]

whether I am professional or not here makes little difference. Spigot isn't my employer so the opinions have no meaning for me

[wet breach]

its not hard do you store players in a list already?

[lament slate]

I do not no I a mstilll new to coding

Do I have to make a array or string?

[wet breach]

I would probably use a hashmap

[lament slate]

Oh god

[storm crystal]

So what database do I use

[lament slate]

The h word

[river oracle]

whatever you want, I'd go with SQLITE or something

[floral drum]

Before I say anything, I would like to request a lawyer

[storm crystal]

Do i also need to make management classes

Can they be static

[floral drum]

Learn, look it up on youtube or something, this is java!

[wet breach]

Hashmap <UUID, Integer> randomsMap = new HashMap<>(Bukkit.getOnlinePlayers().size())

Random randomNum = new Random();

for (int assignNum : Bukkit.getOnlinePlayers().size()) {
    randomsMap.put((players UUID), randomNum.nextInt());
}

[floral drum]

wottttt

frostyyy

[lament slate]

Thank you

[wet breach]

its not complete as you will need to figure out how to get players UUID's and put them in

[floral drum]

hiii

how are you bestie

[wet breach]

or just use player names since its only used when they are on anyways

[storm crystal]

Mhm

[wet breach]

https://tenor.com/view/best-friend-love-you-gif-23187603

[floral drum]

!!!!

[lament slate]

Frsoty thanks you your very nice and Ima go try to code this now

Have a great day/night

[wet breach]

notice I store the random object and not make a bunch of random objects 😛

always avoid if you can in making new randoms, its one of few objects that will cause you issues later down the road lmao

[lament slate]

Oks

[storm crystal]

Do i just make connection to db at server enable and keep it like that

[floral drum]

You usually connect to the db once, or create a db pool so it can swap around connections when sending multiple queries.

weeeee

[storm crystal]

Whats a pool

[wet breach]

There are some things where we can't really tell you because its dependent mainly on you. What you prefer, what you know, what kind of data and how much data, does it need to persist or not etc. If you want a DB for learning purposes either go with sqlite or mysql as there is plenty of resources and tutorials online to guide you in the appropriate direction to learn about this. There is more to DB's then just using them, such as setting the DB tables up properly etc IE their structure and the sorts.

[floral drum]

A pool is basically multiple database connections, it basically allows parallel queries to the database without exhausting the single connection

not sure if I was correct there

[wet breach]

learning proper DB management is like a whole course in of itself just fyi
