[slender elbow]

and naturally the handlers list itself will also be in the companion object

[modest tartan]

Ok so how would I do the companion object, I don't intend to be fed but I haven't given them a look

[ancient plank]

kotlin is pretty easy to understand tbh, I can read it okay-ish but I can't write it because I don't know it

[slender elbow]

class BlahEvent {
  companion object {
    // ... static handler list stuff
  }
}

[modest tartan]

Yeah I'm still a bit lost.

I've got this ```kotlin
private val HANDLERS = HandlerList()

override fun getHandlers(): HandlerList {
    return HANDLERS
}

companion object {
    val handlers = HandlerList()
    fun getHandlerList() : HandlerList {
        return handlers
    }
}

Should I make the companion object extend event?

Cuz this doesn't work and I tried a couple guesses already that all didn't work still. The issue is that when I use the companion it can't find any of the pieces its looking for so idk how this helps. I know I'm not understanding something

[tender shard]

no, you're having two HandlerLists. The instance getHandlers() method must return the companion object "handlers" object, too

you are creating two separate HandlerList objects

[modest tartan]

I just got it figured out I think I have this now ```kotlin
companion object Event {
val HANDLERS = HandlerList()

    @JvmStatic fun getHandlerList() : HandlerList {
        return HANDLERS
    }
}

[tender shard]

class MyEvent : Event() {
    
    companion object {
        private val HANDLERS = HandlerList()
        
        @JvmStatic
        fun getHandlerList(): HandlerList {
            return HANDLERS
        }
    }
    
    override fun getHandlers(): HandlerList {
        return HANDLERS;
    }
    
    // Other stuff
}

sth like this should do

[modest tartan]

Yup

Appreciated

Thank you both

[tender shard]

(the whole design is flawed anyway though lol)

[modest tartan]

What design is flawed?

[inner mulch]

How?

[tender shard]

I meant bukkit's event system, not the code sent. It feels pretty weird to require BOTH, a static get handler method, AND an instance method returning the same handler list. should be a registry taking in a Class<? extends Event> instead or sth

[young knoll]

We didn’t have generics back then!

[sullen marlin]

pretty sure it's done that way as an 'optimisation'

no map.get(..) call, baked into the event itself

[young knoll]

Event system overhaul when

[remote swallow]

when we do mor ebreaking changes

we can make y2k write all the commodore

[tender shard]

But whats the purpose of the static method

[sullen marlin]

static method is for registration

instance method is for calling

[tender shard]

Ah ok

[remote swallow]

does the server lag if i registered my player move event listen 25 times

[young knoll]

These days you could avoid the map.get with like

A collection of consumers

[tender shard]

Who cares, you dont have any players anyway

[sullen marlin]

no, because how do you get the consumers for an event

[remote swallow]

true

[young knoll]

Right

Oh I know, ASM!

[tender shard]

Gson somehow is able to get around type erasure or sth

[sullen marlin]

think you're both missing the point

[tender shard]

Probably

[sullen marlin]

the point is it eliminates a Map<Class, EventConsumerCallerThingyMajig>

[tender shard]

I‘m a coding noob, dont ask me questions or assume that I know things

[young knoll]

Lol

[sullen marlin]

because rather than map.get(event.getClass()) you just have event.getEventConsumerCallerThingyMajig()

[tender shard]

All i know is that kotlin is great (pls dont ban)

[ivory sleet]

banned

[remote swallow]

conclube

have you ever heard of cat ears

[tender shard]

Again? Conclube?

[ivory sleet]

yea :,)

[ivory sleet]

UwU

[young knoll]

Conclube gave me my ears

Remember

[remote swallow]

i wonder if conclube happens to have 6 bucks spare

hes poor so probablynot

[young knoll]

So are you

[ivory sleet]

Hmm I can see what I can do once I get home

Im in italy rn

[remote swallow]

why are you there

of all places

[young knoll]

He went to grab a pizza

[remote swallow]

might run into the one who we wont name

[ivory sleet]

Why not? :P

[ivory sleet]

?

Did I miss someone?

[remote swallow]

who is supposedly from italy

that we wont name

[ivory sleet]

Idk

Pope?

[remote swallow]

conclube

use brain cells

[ivory sleet]

the one who I banned?

[remote swallow]

maybe

[ivory sleet]

ah ok

[remote swallow]

idk if you banned them

[young knoll]

Yeah he banned the pope

[native gale]

In which order plugins are loaded?

[remote swallow]

i think its just alphabet

[native gale]

Hm, okay

[tender shard]

nope

1. output of listFiles()
2. sorted by their "load order" in plugin.yml

[remote swallow]

well yeah

im pretty sure list files is alphabet

[tender shard]

that means:
on linux: random
on windows: by alphabet

and then ofc by their depend/softdepend

[tender shard]

on linux it's by inode iirc

[remote swallow]

ah

[tender shard]

definitely windows goes by alphabet but linux doesnt, so I assume linux goes by inode

macOS: no clue, probably inode too

[inner mulch]

can i set entitytype.snowball invisible?

setInvisible didnt work

[tender shard]

send your code please. it should work. iirc it's possivle to make eggs invisible, so it'd be weird if snowballs wouldnt work

[inner mulch]

does it maybe have to do with the fact that im doing it with packets?

[tender shard]

?nocode :p

[undone axle]

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

[sleek estuary]

Is it recommended to check to avoid overflow even though it is not likely to happen?

[inner mulch]

i will try it with api first, if that doesnt work i will send the code, i think my packet usage is the problem

[worthy star]

is Foundation API actually good? (https://github.com/kangarko/Foundation)

[echo basalt]

It's only used by minecademy ppl

[worthy star]

it looks good tbh

[native gale]

Idk, I avoid plugins that use this

Because it once mangled my server.properties

[worthy star]

how?

[native gale]

And it was a huge headache to figure out what exactly caused that

[native gale]

IIRC, at some occasions it tries to place an ad there as comment

At the same time it saves it in wrong encoding

[echo basalt]

mm auto registering

fancy

I hate anything that scans shit with reflections and auto registers magic

[native gale]

Since my motd contains Japanese characters, every time I started a server it was turning into mahsed potato of symbols

[worthy star]

so its not really good

[native gale]

Idk how good it is, I avoid it

[worthy star]

i mean, the bro spent so much time on it

[echo basalt]

The code's clean but it's just not great

[worthy star]

each package has packages with classes

[echo basalt]

and the reputation it brings is whatever

[inner mulch]

?paste

[undone axle]

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

[echo basalt]

The other thing is you don't learn much by using all the libraries already made

[worthy star]

real

[echo basalt]

And if you want to disassociate one day you're fucked and have to learn everything again

[inner mulch]

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

[tender shard]

it will never hurt to check it anyway.

[worthy star]

best thing is
learn how the original thing works
make your own private api

[sleek estuary]

But I wanted to know if it's a good practice or not

[tender shard]

I even have to do things like this:

does Bukkit.getPlayer(playerName) actually return something in PlayerDeathEvent?

Because some plugins create a fake player and stuff like that... so yeah, better check twice!

in fact I got 3 NPC checks lol

[sleek estuary]

wtf? why do you use bukkit.getplayer(player.getname))?

if player was null, it would throw a nullpointerexception when executing player.getname

[tender shard]

because some plugins call a PlayerDeathEvent with their custom Player object. And ofc Bukkit.getPlayer(customPlayer.getName()) then returns null

(for example Citizens iirc? Or another NPC plugin, I don't remember)

[sleek estuary]

why would an npc call this event

[tender shard]

because that plugin calls that event

spigot itself doesnt call the event, but the respective NPC plugin calls it

[native gale]

Check #general

[tender shard]

and then you end up with this:

where 277 is this

[sleek estuary]

1112 omg -'

[remote swallow]

ew main.getserver

where Bukkit

[tender shard]

you're the ew dude

[maiden thicket]

TRUE Bukkit.getServer the goat

[tender shard]

preferring static hacks over the DI'd server instance? epic, fr?

[remote swallow]

Bukkit.getPlayer > Bukkit.getServer().getPlayer > PLUGIN#getServer().getPlayer

[tender shard]

No.

[maiden thicket]

TRUE

[native gale]

I prefer the last one btw

[sleek estuary]

Why do you pass the event to the method instead of just passing the player instance?

[maiden thicket]

Bukkit#getPlayer easier to write fr

[tender shard]

passed server instance > Bukkit.get....

[native gale]

Because I do that in Kotlin and it lets you just write

server.getPlayer()

[tender shard]

because, as I said earlier, angelchest's code is a mess

I'm a lawyer and not somebody who studied O(n^2) shit lol

[maiden thicket]

also

plugin.getServer = Bukkit.getServer

[sleek estuary]

here is not the player instance, you used bukkit.getplayer. If this is within that spawnangelchest method, why didn't it just pass the player instance?

[maiden thicket]

same reference

it comes from Bukkit.getServer

[tender shard]

depends - never used MockBukkit?

[maiden thicket]

no im looking at paper right now

no idea what mockbukkit is

[tender shard]

for unit tests it's pretty normal to pass in a custom class implementing Server

[maiden thicket]

this isn't a unit test

they initalize the Server field in the javaplugin class with bukkit.getserver

[tender shard]

no ofc not, but that class is tested through unit tests?

[maiden thicket]

idk

[tender shard]

why would I rely on the static Bukkit.getServer() if I already got a Server object?

[maiden thicket]

easier to type and they reference the same thing so tbh it's not a huge issue

[tender shard]

easier to type? does your IDE not feature auto completion?

[maiden thicket]

Bukkit.getServer() versus creating a variable to reference my plugin just to access getServer

[river oracle]

tbh Bukkit#getServer only makes sense if you don't already have a plugin instance

that's what alex is insuating

[maiden thicket]

well yeah but there's no negative differences

[tender shard]

the class I sent has 3500 lines. dw, it's not the only time I access the server

[maiden thicket]

or impacts

it's honestly just depending on the developer

[river oracle]

actually _

[maiden thicket]

okay man

🤓 ☝🏾

[sleek estuary]

you can take 2 points into consideration: performance and organization

If it takes into account performance, using bukkit.getserver is better. if it takes organization it is debatable

[tender shard]

please explain how it's better, and please also explain how (if it's true) it's not considered premature optimization

here's the full source code for that class btw:

https://paste.jeff-media.com/?630d8d777fc3e48c#AxG4eFpJFHtBz4qfeqPUwhw9ksiQwEmF82T4gZEAcDUS

and I know that many of this stuff is very bad

remember, I did not study computer science, and this code was written by me in 2018, when I just started coding

[maiden thicket]

public fields go brrr

[sleek estuary]

passing a variable in the constructor uses memory. the static method avoids this

[young knoll]

If you already have a server instance Bukkit.getServer is an extra method call

But yes it does save like

8 bytes

[tender shard]

yeah I know it's bad. it's kept for backwards compat reasons because I know some other plugins rely o nthose fields being public

[young knoll]

Sorry, 4 bytes in most cases

[maiden thicket]

pretty sure the memory difference is very minimal yeah

allocating a reference to ur plugin vs just accessing it through bukkit

[young knoll]

What will I do without those 4 bytes!

[sullen marlin]

Think of the garbage collection overhead

[maiden thicket]

pretty sure the allocation to the plugin instance is constant runtime

[sullen marlin]

/s

[maiden thicket]

man md_5 just

make getServer() private

[young knoll]

Even worse, if my heap is over 32gb it’s 8 bytes!!!!!11

[maiden thicket]

make everyone access thru reflections

do a little trolling

late april fools update

[tender shard]

tl;dr: yeah I know that my code isn't great. but there's no point in rewriting sth that's working fine

[maiden thicket]

we dont judge for old code

trust

[river oracle]

i'll just use a public static final MethodHandle _ 0% performance loss

[tender shard]

here's an example of me writing good code: https://github.com/SpigotBasics/basics/tree/main

[maiden thicket]

TRUE

[tender shard]

now go and critize this!

[grave notch]

Ok, I'm sure I could've somehow found this out myself but I can't for the life of me figure this out. When I take the decompiled classes for a 1.12.2 or a 1.8.8 version of minecraft from the decompile-latest folder after running BuildTools, there are a few files that have decompile errors with seemingly no patches associated with those files. The one file I'm really stuck on right now is the PlayerSelector.java file, is there something else that spigot does other than patch files that I'm not aware of?

[sullen marlin]

Spigot doesn't use all the files

So if you're adding a new file you need to fix the error yourself

[maiden thicket]

i was highkey waiting for someone ty say 🤓 we don't support 1.8.8 and 1.12.2 here

[inner mulch]

can you reallym ake eggs invisible i tried everything, but .setinvisible doesnt seem to work on entities which arent livingentity

[river oracle]

^ probably even more so in older versions you need to make your own patches

[sullen marlin]

Decompilers aren't perfect

[tender shard]

what?

[sleek estuary]

bro ahahh

[inner mulch]

i cannot make eggs inviislbe

[sullen marlin]

Hide entity / set visible by default

[tender shard]

which version? (client AND server)?

[young knoll]

Can’t you theoretically set their item to air

Or does that explode

[inner mulch]

i cannot hide it because then i cant make it setpassenger

[sullen marlin]

Though if the method is on Entity it should probably work, although that's like the invisibility potion type of inviaibit

[inner mulch]

latest version

1.20.4

[sullen marlin]

So if you can't splash potion it Mojang probably doesn't support it

[sleek estuary]

Even the computer barely detects the difference. you can create Integer.MAX_VALUE of variables and display them in the console and you will not see an increase in memory

[grave notch]

right, so if I just don't include that file it will still compile? I'm sorry I do not know about the custom POM setup Spigot likely uses to accomplish that and I'm just trying to set up a server that I can directly mod for quick experiments, and am not sure how Spigot can get away with not fixing those decompile errors despite BuildTools logging that it decompiled the class

[sullen marlin]

Because it uses the compiled class

Spigot patches like < 20% of the server or something

[tender shard]

people commenting mfnalex' 2018 code:
"huehue mfnalex writes bad code, his code sucks, he does noob mistakes"

mfnalex sends code he wrote this year:
(no answer anymore)

[sleek estuary]

md_5 are you the dev of velocity?

[inner mulch]

so eggs cant be invisible?

[tender shard]

no

[inner mulch]

is there any entity with not hitbox which can be invisible

[sullen marlin]

Idk test with a /summon command in vanilla

[young knoll]

Did you try setItemStack

[sleek estuary]

oh ok thx

[inner mulch]

im not using dropped itemstack

[young knoll]

Or setItem or whatever it is

[inner mulch]

i have a real egg

[young knoll]

Yeah but projectiles have a method for that too

[grave notch]

ok so what makes Spigot use compiled classes in place of source files during jar creation? There's like 10 POM files and I am not good with Maven lol

[inner mulch]

hmm

ok

i will try

[tender shard]

md_5 = spigot and bungeecord
everything else = someone else

[young knoll]

ThrowableProjectile#setItem

[sleek estuary]

I'm not just "someone else", okay?

[inner mulch]

i will set it to air, good idea

[tender shard]

ok

[sleek estuary]

When they ask you this, include my name with my projects

[sullen marlin]

A dependency on the original jar

[sleek estuary]

Thank you for your attention

[inner mulch]

setitem doesnt seem to do anything

[young knoll]

Try with something other than air

[inner mulch]

it works

[young knoll]

Alright then it doesn’t like air

[inner mulch]

maybe it would work but the itemstack creation doesnt work?

can i create a itemstack of air?

[young knoll]

Yeah

[inner mulch]

yo what is Material.CAVE_AIR

[young knoll]

Cave air

[rough ibex]

its air that generates in caves

theres also VOID_AIR

just use AIR

[inner mulch]

it doesnt work tho

air itemstacks dont work

it just defaults to snowbal

l

[young knoll]

Well if you had a resource pack you could solve that

[inner mulch]

any ideas to create an entity with no hitbox, which can be invisible, but not hidden? invisible but still exists client side?

[young knoll]

Marker armor stand

Display entities

Interaction entity

[inner mulch]

problem is it has to be a perfect size like the snowball, so that i can make my hologram have lines

i need entities in between

i cannot use display entities as im supporting bedrock

[young knoll]

F

Bedrock sucks

[inner mulch]

i hate bedrock too, but crossplay servers are better as every1 can play on them

[young knoll]

Well with enough effort you can just use bedrock stuff for bedrock players

[inner mulch]

yes but there is no bedrock stuff

for this

or is it

*there

[young knoll]

Bedrock can have custom entities

[maiden thicket]

fr?

i saw that being done from the server side and i was like huhhh

[swift void]

oes anyone know of an plugin that can do something like the dungeons in the game Trove, where they are randomly generated around the world and have mobs placed inside them?

[drowsy helm]

a custom world generator with structure support can do this

[worldly ingot]

I'm sorry

import de.jeff_media.daddy.Daddy_Stepsister

Nobody's gonna mention this?

[rough ibex]

nope

[valid burrow]

ive seen worse

[worthy yarrow]

public class PetRegistry {

Any suggestions for more methods? I was thinking of refining the registry to take / store any instance of a pet class but didn't have the time to actually mess with it

[spiral bramble]

Hey there, I haven't touched plugin development in 5 years so I'm looking for some help with saving Player Data.

I've made PlayerData and WandData classes, and the yaml is saving as:

[[REDACTED]]: !!com.starfluxgames.basicwands.configurators.PlayerData
  wands:
  - amplifier: 1.0
    appliedPotion: BAD_OMEN
    cooldown: 10.0
    duration: 10.0
    self: true
    wandType: DIAMOND_SWORD

Although upon either reloading the config, it complains that Global tags aren't allowed !!com.starfluxgames.basicwands.configurators.PlayerData

I'm not sure if I'm missing something here. Any pointers are appreciated. Thanks

[worthy yarrow]

I may be 100% incorrect, but pdc should be your fallback for persistent data. 1.14+, not too difficult

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[spiral bramble]

Thanks, wasn't aware of that I'll have a look into it.

[worthy yarrow]

It's the modern way to persist data nowadays so have some fun

[spiral bramble]

I'm guessing config files are still using FileConfiguration? Or has that changed too

[worthy yarrow]

iirc, yes should be fine

I still use fileconfiguration with no issues

[spiral bramble]

Brilliant thanks

[worthy yarrow]

No worries!

[worthy yarrow]

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

Could I get some notes / suggestions on this structure/implementation?

[sullen marlin]

maybe an AbstractPet for uuid, name, level

[worthy yarrow]

The logic for each pet ability would still have to be written individually no?

[sullen marlin]

yes but only the pet specific stuff

[worthy yarrow]

Right right yeah you're right

Considering the abstract bit, would I still implement the interface?

[sullen marlin]

yes

[worthy yarrow]

Ok and I'm doing this to keep common methods among all pets I assume?

Right

Alright let me work on the abstractpet

and then probably just chicken abilities for now

I want to go for something similar to the saicopvp chicken pet where you take no fall damage and I'm pretty sure it changed your gravity iirc

[glad prawn]

naming it Pet is fine not need to AbstractPet

[worthy yarrow]

only reason it's abstractpet rn is because the interface is currently called pet lol

my psychology book says it's most likely because you eat when you think about that

or have in the past

[glad prawn]

So make your Pet class abstract?

[worthy yarrow]

If you're thinking about it that much then that's your likely answer lol

[worthy yarrow]

I'm working on it man jeez

[spiral bramble]

Apologies if I'm misunderstanding PDC here,

I've got myself setup with

public class PlayerData implements PersistentDataType<byte[], UUID>

This is just storing a UUID correct?

Are there any examples on storing an entire serialized class? ie.

public class WandData {
    public String wandType;
    public String appliedPotion;
    public float duration;
    public float amplifier;
    public float cooldown;
    public boolean self;
}

^ Reading the examples for toPrimative and fromPrimative it looks like it's serializing the byte[] directly

[worthy yarrow]

https://pastebin.com/JJnLDU2V
There's this string array example from the pdc link if it helps

[spiral bramble]

I'll take a peek thanks

Yeah, so this is essentially breaking the string down into it's bytes directly

Oh boy this is gonna be fun

[sullen marlin]

put each value as a different pdc key and assemble it that way?

theyre all primitive typs

[spiral bramble]

I'm looking to store a List<WandData>

Ah I get what you're talking about now

https://pastebin.com/G8eyBMg9

Is this what you mean? 😅

Obviously I'd need some helper methods, but that's my idea

[sullen marlin]

yeah something like that

[worthy yarrow]

Looks fine to me

[spiral bramble]

I miss my JSON serialization 😂

Thanks, I'll see what I can get going

[worthy yarrow]

I was made aware of a cool thing with the namespacedkey: private static final NamespacedKey chickenPetKey = NamespacedKey.fromString("coolpets:chicken_pet_key"); requires no real instance of the main

this convo

[worthy yarrow]

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

How does this look?

[tender shard]

it's been mentioned more than once lol

[tender shard]

pls don't name the api "API" but rather "PetsAPI" or "CoolPetsAPI" or sth

[worthy yarrow]

haha it was just temp

[tender shard]

ah ok. besides that, looks good

[worthy yarrow]

i was refactoring everything to implement pet, interface was originally called pet

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

How about the two util classes, the taskManager is only written out to handle chicken pet rn

[tender shard]

why is your TaskManager a singleton? Why not just static methods?

And you're still not caching the namespaced key in line 20 of that paste

oh and what's runChickenTasks? 🥲

[worthy yarrow]

I think I forgot, only had like half hour before work when we were talking

[worthy yarrow]

singleton cuz it was originally to just manage chicken pets, but now I implemented an abstract pet class so I'm just gonna use it to handle all pets

[worthy yarrow]

And finally, I uh haven't done a lot with tasks

private final NamespacedKey chickenPetKey = ChickenPet.getChickenPetKey();

private static boolean isPetInsideInventory(Player player, UUID petId){
        for (ItemStack items : player.getInventory().getContents()){
            if (!(items != null && items.hasItemMeta())){
                return false;
            }

            ItemMeta itemMeta = items.getItemMeta();
            PersistentDataContainer container = itemMeta.getPersistentDataContainer();

            if (container.has(chickenPetKey, PersistentDataType.STRING)){

                String petIdString = container.get(chickenPetKey, PersistentDataType.STRING);

                if (petId.toString().equals(petIdString)){
                    return true;
                }
            }
        }
        return false;
    }

So is this fine?

I'll put it into a flat file later when I get to that bit

[trim lake]

Im working on custom autopickup plugin and how can I handle mending enchant? I kinda dont want repair item with own method and want to keep PlayerItemMendEvent to be called and let MC repair that item, is there any way? I want exp to be autopicked up (give to player) as well

[tender shard]

you can't just call an event and expect the server to do vanilla stuff

that's not how events work

[trim lake]

hmm, so it will not be possible in that case probably?

[tender shard]

you'll have to actually recreate the original mending behaviour. I'm currently greping my IntelliJ folder to find how I'm doing it, because I also had to do this once

[trim lake]

Im making that for server with using own custom durability of items and kinda want to be ezy to hook to it ideally true MendEvent. This custom durability is one of reasons Im making that autopickup plugin so 😄

[trim lake]

that will help a lot. basicly I need to "naturally" let player pickup xp.

[tender shard]

ok weird - in my Drop2InventoryPlus plugin, I have commented out MendingUtils and it still seems to work somehow lol

[trim lake]

u are giving xp from breaking block directyl to player with Player#addXp (or how its called) method?

[tender shard]

tbf I have no idea what I am or was doing regarding XP

auto pickup plugins are a mess

tbh I really have no idea how I'm doing it in Drop2Inv. I only know that I'm only calling giveExp and somehow it works. I have searched the whole project for the "mending" string and I found nothing, but somehow it still works

I also looked into CraftPlayer#giveExp and there's no mention of mending either

[worthy yarrow]

ghost functionality 😄

[trim lake]

loooks like u are saving the ExperienceOrb from events (witch will be problem bcs Im cancelling exp drop) and probably mending will edit that orb and what left will add to player? Im kinda confused. But I was thinking about same method kinda... but will be pain to do it anyway lol

[flint coyote]

Well the mending is probably tied to xp increase instead of xp pickup. Therefore you don't have to explicitly do anything

[tender shard]

yeah but all I'm doing with that map is this

[trim lake]

nah, medevent is not called when u give XP to player with method

[flint coyote]

oh alr

[tender shard]

was Enchantment.MENDING renamed at some point or sth maybe?

[trim lake]

nop

[tender shard]

then sorry, i have no clue how I was doing it

[trim lake]

no worries, so u are not seting xp drop in BlockBreakEvent for example? bcs Im setting it to 0 and before that I will do event.getPlayer().giveExp(event.getXp()) to prevent double pickup of them

I will try to find a way to let player pickup exp naturally somehow

[tender shard]

These are the base listeners of my auto pickup plugin

https://paste.jeff-media.com/?a9680384be1d391b#6CExGcQZ6YWVRnVHt1dmkJPvNZb3SHKkXGfmT6ooCqz4

it references EventManager.giveAdjustedXP which I already showed above

EventManager: https://paste.jeff-media.com/?bef3f4d9a3fc08be#2i219SW5kzECDCLVwj2kY3eiucBMXGLSAsAbZPSWuRvw

[trim lake]

perfect I probably got it how I will do it, just spawn orb at player and should be good lol, kinda looks like u are doing that way

it shouldnt be picked up by another player hopefully

[tender shard]

oh yeah probably that's what I'm doing haha

[tender shard]

pretty sure that it'll take the closest player

[trim lake]

I appreciate it that u shared the code! u are always soo helpful! thanks man

[tender shard]

np!

https://repo.md-5.net/content/repositories/snapshots/ appears to be down

[dawn flower]

yo what's a good method to try to fix ghost blocks? if it's even possible serverside (i'm not asking for code i just want a method)

my idea is send block updates more frequently but i'm not sure if that's a good way

like maybe if you can ask the client for the blocks visible to it using nms

[sullen marlin]

thanks, fixing now

ram requirements for everything just keep increasing

[mint marsh]

Thanks for the quick fix 🙂

[onyx fjord]

shouldve used reposilite

i think it needs like 48MB of ram

[ivory sleet]

Yea reposilite isnt such a bad software

[pliant topaz]

How would I get the the item a player has placed into a custom gui? Cause I cannot figure out how I'd get the item as when the event (InventoryClickEvent) is triggered it is still null

[lost matrix]

InventoryClickEvent is the way to go.
And there are multiple ways of bringing an item into your custom GUI (eg shift clicking).
Do you need the item to be detected immediately? Otherwise i would just scan the Inventory for added items in the InventoryCloseEvent.

[pliant topaz]

yes, i need it to be detected when the item is placed in the inventory

the problem is i cannot get the slot where the item was placed and even if it'd be null apparently

[lost matrix]

Because the item is still on the cursor of the player at that point in time.

[pliant topaz]

ik

is there any way I could check in which slot the player wants to move th item into?

[gleaming frost]

Hello does anyone know how i can stop furnaces from dropping xp when broken? setting the blockbrokenevent exptodrop to 0 doesnt work.

[ocean hollow]

how can I remove 100 itemStacks from inventory?

public static void removeAmount(Inventory inventory, ItemStack itemStack, int amount){
    ItemStack cloned = itemStack.clone();
    itemStack.setAmount(amount);
    inventory.removeItem(cloned);
}

``` I wrote this, but it doesn't work

it only takes one item

[mint marsh]

Use Inventory#remove instead https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/Inventory.html#remove(org.bukkit.inventory.ItemStack)

[ocean hollow]

it does nothing, if I do it using Inventory#remove

[ocean hollow]

It says that it only works in the case of amount = itemAmount

but I have 64 items, but I need to remove only 5, for example

[mint marsh]

for loop? 😅

[ocean hollow]

oh. ok 😦

[mint marsh]

I've never worked with inventories

[lost matrix]

This should work. Did you debug the method and made sure that the amount isnt set to 1?

[ocean hollow]

I did it using for, and everything works just fine

what is the difference between yaw, pitch and direction. One is in the angles, and the other is like a vector, don’t they describe where the player is looking, for example?

[lost matrix]

So you simply wrote the same logic which already existed again...

[lost matrix]

Yes

[echo basalt]

Yaw is your left-right rotation

So if you look right your yaw increases type deal

The default value is 0 which is facing +Z iirc

Pitch is your up-down head rotation

So if you look up, the pitch increases

The default value is 0 which is facing straight ahead

[ocean hollow]

if I change the vector, will yaw and pitch change?

[echo basalt]

Your direction is what happens when you grab your yaw/pitch angles and you convert them to a Vector

So if you look up it's 0,1,0

The only way to change yaw/pitch is to teleport the player to the new position

That has the new angles

(Or force the player to spectate an entity that's being teleported)

[ocean hollow]

    private static Location addLocation(Location location, double x, double y, double z){
        Location result = location.clone();
        double cosPitch = Math.cos(Math.toRadians(location.getPitch()));
        double sinPitch = Math.sin(Math.toRadians(location.getPitch()));
        double cosYaw = Math.cos(Math.toRadians(location.getYaw()));
        double sinYaw = Math.sin(Math.toRadians(location.getYaw()));

        double newX = x * cosYaw * cosPitch - z * sinYaw * cosPitch - y * sinPitch;
        double newY = x * sinYaw * cosPitch + z * cosYaw * cosPitch + y * cosPitch;
        double newZ = x * sinPitch + z * cosPitch;

        return result.add(newX, newY, newZ);

        Location bulletLoc = addLocation(location, dX, dY, dZ);
        Bukkit.broadcast(Component.text(location.toString()));

        Vector oldDir = location.getDirection().clone();
        Vector newDir = new Vector(oldDir.getX() - dX, oldDir.getY() - dY, oldDir.getZ() - dZ);

        bulletLoc.setDirection(newDir);
        Bukkit.broadcast(Component.text(bulletLoc.toString()));
        return bulletLoc;
    }

I wrote this, but nothing happens. locations continue to be identical

[lost matrix]

What are you trying to do?

[umbral ridge]

don't use chatgpt

[ocean hollow]

i am trying to offset it

[lost matrix]

To achieve a random spray pattern?

[ocean hollow]

so that the "display entity" flies out from the muzzle, and not from the player's eyes

[lost matrix]

This will depend on the client setting as well. Keep in mind that some people are left handed.

[ocean hollow]

I can ignore that other people are left-handed)

[gleaming frost]

Is it possible to access a furnaces inventory on the block break event ?

[lost matrix]

Here is what you should do:

1. Trace the impact Location
2. Change the origin Location to your gun
3. Calculate the vector from impact to origin (convert to vectors and subtract [impact - origin])

This will give you a new Vector which points from your origin (the gun) to your impact.

[lost matrix]

Sure, the Block isnt broken yet so you can still get its BlockState and modify it.

[rapid vigil]

uhm a question that gets me curious, if all events happen before the action is done whats the point of having "Pre" in some event names, its always gonna be pre

like pre command preprocess or pre async join etc

[lost matrix]

Probably just for clarification

[rapid vigil]

then they should add Pre to all event names :p

[echo basalt]

or what I usually do

change the original eye location's yaw and pitch by a tiny amount before tracing

that's random spray

as for the gun thing yeah you need uh magic

[quaint mantle]

https://paste.md-5.net/jajiyexiwu.cs
was wondering if someone can help solve this invName and invtype area i can't figure out what to put there

[echo basalt]

Looks AI generated

?gui

[undone axle]

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

[gleaming frost]

how would i specifically display its inventory in console im finding it difficult to find the corrects methods

[echo basalt]

You shouldn't compare inventory titles in the first place

[quaint mantle]

not really my friend gave it to after mine failed after trying a million times

[echo basalt]

Get the block state, check if it's Furnace and get the inventory after casting

[gleaming frost]

casting to furnace?

[lost matrix]

1. Get the BlockState
2. Cast to Furnace

Here are all methods like getting its inventory etc:
https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/Furnace.html

[ocean hollow]

It turns out that if I change the direction, then the pitch and yaw will automatically change, or do I need to calculate it manually?

[lost matrix]

No you dont. The direction is literally defined by the pitch and yaw.

It only difference is that it also has a length

[echo basalt]

Which is usually 1

[ocean hollow]

so code may be look like?

[lost matrix]

What is dx dy and dz?
This looks a bit weird

[gleaming frost]

anyone know where the internal xp is stored of the furnace block?

[ocean hollow]

deltaX, deltaY, deltaZ, for offset for bullet start Location

[lost matrix]

  public Location calculateBulletPath(Location gunLoc, Location impactLoc) {
    Vector direction = impactLoc.toVector().subtract(gunLoc.toVector());
    Location bulletLoc = gunLoc.clone();
    bulletLoc.setDirection(direction);
    return bulletLoc;
  }

[ocean hollow]

thank you, now it works

[ocean hollow]

lol, but how can I find start gunLoc?

        Location result = location.clone();
        double cosPitch = Math.cos(Math.toRadians(location.getPitch()));
        double sinPitch = Math.sin(Math.toRadians(location.getPitch()));
        double cosYaw = Math.cos(Math.toRadians(location.getYaw()));
        double sinYaw = Math.sin(Math.toRadians(location.getYaw()));

        double newX = x * cosYaw * cosPitch - z * sinYaw * cosPitch - y * sinPitch;
        double newY = x * sinYaw * cosPitch + z * cosYaw * cosPitch + y * cosPitch;
        double newZ = x * sinPitch + z * cosPitch;

        return result.add(newX, newY, newZ);
    }``` I have this, but it is incorrect

if there is -1 for x or -1 for y, then it will shift down

moving forward is not a problem, but right/left, down/up

[lilac dagger]

did you try Vector direction = location.getDirection();?

assuming it's the direction you want

[lost matrix]

  public Location getGunLocation(Location eyeLocation) {
    // The hard part is finding those magic numbers.
    double forwardOffset = 0.5;
    double rightOffset = 0.3;
    double downOffset = 0.3;
    Vector direction = eyeLocation.getDirection();
    
    Vector adaptedForward = direction.clone().multiply(forwardOffset);
    Vector adaptedRight = direction.clone().crossProduct(new Vector(0, 1, 0)).normalize().multiply(rightOffset);
    Vector adaptedDown = new Vector(0, -1, 0).multiply(downOffset);

    return eyeLocation.clone().add(adaptedForward).add(adaptedRight).add(adaptedDown);
  }

[lost matrix]

Not a development related question i would argue

[spare prism]

i wasnt sure where to post it because i generate this command in my plugin sorry

[young knoll]

Use McStacker

[acoustic pendant]

How can i have a string like this: 1,2,14,15,19 and split it to get every number? I'm thinking on using #split and a loop but not sure

[worldly ingot]

You’re thinking right

[lost matrix]

You should def not generate this command in plugins. Spigot has a perfectly fine API for that.

[acoustic pendant]

i''l try then

[spare prism]

wdym?

got ya

but

i have to get all the nbt from an item

and apply it to the command

[young knoll]

Why do you need the command tho

The api is perfectly capable of giving an item to a player

[spare prism]

I'm making a plugin that would generate a /give command from an item in hand

it should support all the nbt data

PDC is not enough, cause it doesn't cover all the nbt

[spare prism]

its a good website as i see, but it doesn't help with my case

[young knoll]

Well all the data will be part of the api

But it might be a bit of a pain

[spare prism]

i get NBTCompound with a library and just parse it to a json

[acoustic pendant]

 String boughtPets = plugin.data.getConfig().getString("Available." + player.getName());
                    String[] ids = boughtPets.split(",");
                    int number = ids.length;
                    if (plugin.data.getConfig().getString("Available." + player.getName()) != null) {
                        for (int k = 0; k < number; k++) {
                            if (Objects.equals(ids[k], String.valueOf(petManager.getId()))) {
                                //code
                            }
                        }``` something like this?

[spare prism]

i just dont get why is the item a default one

[lost matrix]

You can save and load a List<Integer> btw. Saves you all this parsing.

[acoustic pendant]

Yea, can do that as well

thx!

[young knoll]

Seems you have an item tag within your item tag

Also wtf is the thrive enchantment

[modern plank]

how do i make an entity look at a certain location?

[ruby ermine]

How can I make enchantments on essentials kits such as from efficiency 5 to efficiency 9? If I enter 10 I only get efficiency 5

[young knoll]

You may have to enable the unsafe enchantment config setting

[ruby ermine]

            );
            sendPacket(player, packet);```
what's the alternative to this in 1.20.4

[chrome beacon]

Just use the API?

[lost matrix]

Player#sendBlockChange()

[dawn flower]

yeah my little brain didn't realize that

just found it on accident

[undone axle]

Please paste your pom.xml file, or build.gradle (or build.gradle.kts) if you're using gradle on the following website: https://paste.md-5.net/

[dawn flower]

so uh i sent a fake block update to the player and i want to listen for when he breaks the fake block, i used my tiny brain and thought of a packet listener but the thing is it sends 2 packets, one for when you start digging and one for when it's broken and i'm really confused, i tried to use my last 5 brain cells to debug the fields maybe there's a field that tells you if the block was broken was attempted to be broken but there are 0 fields

what should i do?

[kindred sentinel]

Is there any pom.xml tutorials?

[dawn flower]

why do u need a tutorial for pom.xml..

[lost matrix]

If you install the minecraft development plugin in Intellij and let it generate a default spigot maven project, then the pom is quite good.
pom.xml is basically a configuration file for your maven project.

[dawn flower]

yeah and if you need dependencies 99% of the time they provide a copy paste

[kindred sentinel]

but there are enough useless stuff

like shading

I wanna try to make it by myself

[dawn flower]

you don't have to worry about shading tbh

pom.xml is usually covered on basic java tutorials so look for that

[kindred sentinel]

oh ok thanks

[ocean hollow]

the same with Random

[dawn flower]

?

[ocean hollow]

but it takes argument

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

and if you are stuck at one point ask here

thats way more efficent than looking for a tutorial you will forget 2 days later anyways

PlayerSpawnLocationEvent does not change the rotation

[alpine urchin]

good morning

[grim hound]

like it's a Location, you change everything BUT rotation?

[grim hound]

ohayo

retroopaj

h

make em array instead of maps for your packet listeners

[alpine urchin]

you tell me to do a lot of stuff hm

[grim hound]

just this

cuz it hurts me knowing the performance could be this enchanced

[alpine urchin]

@grim hound i could optimize it kind of using EnumMaps technically

[grim hound]

okay lemme just rewrite that whole class for you

[alpine urchin]

no

do not

[grim hound]

array

is

speed

map is also speed

but array is more speed

[alpine urchin]

why u keep telling me what to do

[grim hound]

like I said

[alpine urchin]

go make ur own project

[grim hound]

I am

[grim hound]

this ruined my plans

cuz now I have to TELEPORT the player

which is slower

than a location set

PERFORMANCE NOOOO

[alpine urchin]

having readable/understandable code is also important

and your idea makes it more difficult for people removing and adding listeners

later on

so i say no to your idea

[grim hound]

ehhhh does it really?

but it

s like 7 times faster

[river oracle]

I'm so confused what the fuck

        registerSubcommand(object : Command(CommandLabel("deserialize", "test.test")) {
            override fun execute(sender: CommandSender, args: Array<out String>?): Boolean {
                val player = sender as Player
                val deserialized: ItemStack = GenericAdapters.INSTANCE.deserialize(serialized, ItemStack::class.java)
                player.inventory.addItem(deserialized)
                player.sendMessage("Deserialized Stack")
                return true;
            }
        })```
`TestCommand.kt:25:13 'execute' overrides nothing`

it literally overrides something, I feel like I need to nuke gradle

[eternal oxide]

setting a location and teleport are the same under the hood

[alpine urchin]

yes, really think through your idea gain

again

but its already a no from me to accepting it

you can use reflection to replace my event manager with your idea on your own platform

[river oracle]

fixed it smh had to remove out and ? because its not nullable and just a string array fml kotlin

[alpine urchin]

and override my methods

[grim hound]

that'd be disrespectful

am just finishing

i'll send you the class

[alpine urchin]

no

i dont want it

[grim hound]

think it through

[alpine urchin]

bruv

[grim hound]

too late

[alpine urchin]

on your own plugin that shades packetevents you can overide methods in my event manager

simple

does it the way you want

[river oracle]

but he wants you to instead to adopt his listener platform!

[alpine urchin]

that's a red flag

[river oracle]

no its not you just don't understand how its better. Providing an option to make your own is not good enough

[alpine urchin]

your sentence was written confusingly

but like if someone says no, continually trying to shove it up their throat for weeks or whatever isn't smart

sure you can make an issue on githbu and ill look at it

[grim hound]

my mind is too rotten

[alpine urchin]

show your code idea on github issues

your idea

or whatever

and ill just look at it

and we'll see

But these plugins are best quality... I am a Youtuber

[alpine urchin]

@tidal glacier hi

what u need?

[tidal glacier]

Hey!

I need help in translation of my plugins

[alpine urchin]

fom what language to what

[tidal glacier]

I have purchased these plugins for 150$ each

[tidal glacier]

Turkish to English

[alpine urchin]

i only know english

[grim hound]

like I said

[tidal glacier]

You can use Google translator

[alpine urchin]

i can try using google translate to evaluate

[grim hound]

.

[alpine urchin]

what it should be

okay sure @tidal glacier

lets talk in dms

[tidal glacier]

The problem is not translator

[grim hound]

ADD ME TOO

[alpine urchin]

dont add him

[tidal glacier]

The problem is how to translate the plugin.

[grim hound]

brah

[alpine urchin]

you only use your listeners array

inside one method

[tidal glacier]

@alpine urchin
Accept my request

[alpine urchin]

u didnt incorperate priorities in my event system at all

[grim hound]

I did

[alpine urchin]

no unregister method uses your listeners array

not in this https://paste.md-5.net/aciletuxip.java

some still use the map

[alpine urchin]

okay

[grim hound]

I don't think you understood how that class works

[alpine urchin]

thought your idea was rely on arrays only

and ignore the map

so whats ur idea

who has to die?

[quaint mantle]

i’m trying to make an enchantment called QuickDraw and than another one called SwiftShot, these 2 can’t be on at the same time, can only be on a bow or crossbow, the first level of quickdraw pulls back the bull at 15% more, level 2 is 30% more, and level 3 45% more. SwiftShot makes the bow more accurate so the “bulletdrop” is smaller for when you are farther away.

[quaint mantle]

you.

i have tried to code it but i do all the steps i make the rarity, what it can be enchanted on, and all of that but then for the first one rn i have NO idea how to make the bow pull back faster

[hybrid spoke]

dont think you can fuck around with the bow since thats client sided iirc

but you can manipulate the velocity of the arrow if its shot sooner

[tidal glacier]

Hey!

[quaint mantle]

if i can’t then i will just make a procedure that replaces the bow as soon it gets enchanted with the enchantment making it an exact replica of a normal bow but it says the enchantment

float[] display2Matrix = {1.0000f,0.0000f,0.0000f,0.0000f,0.0000f,1.0000f,0.0000f,0.0000f,0.0000f,0.0000f,1.0000f,0.0000f,0.0000f,0.0000f,0.0000f,1.0000f};

display1.setTransformationMatrix(new Matrix4f(FloatBuffer.wrap(display1Matrix)));
display2.setTransformationMatrix(new Matrix4f(FloatBuffer.wrap(display2Matrix)));

display.addPassenger(display1);
display.addPassenger(display2);

The resizing of display1 works fine, it goes half the width like I would expect. However, I would expect it to be two blocks above display2, but they render inside each other within the game.

What is causing this? It's like the passengers can not exceed the width/height of the display itself, but I tried setting a height and width on the display and this did not help in any way.

Any ideas? Thanks

thats what gemini told me

[warm bramble]

No difference unfortuantely

The matries I provided works just fine via /summon

[hybrid spoke]

do they work without being set as passengers

[warm bramble]

As in as their own individual block displays?

[hybrid spoke]

yeah

[warm bramble]

Hmm, let me see

Looks like they still render the same

[hybrid spoke]

maybe its how you spawn them, their init location could be important as well

im not that experienced in transformation matrix's

[warm bramble]

I'm jusg using the location of the player

[hybrid spoke]

and if you add the y to the one which should be above?

[warm bramble]

I mean, sure I can do that, but that's a bit of a nightmare, I was hoping I could pass in a bunch of matrix to be rendered

[hybrid spoke]

maybe @lost matrix can help with that

i think he has done more than me with matrixes

[warm bramble]

Okay, I look forward to hearing what they say then

For reference, these display entities can expand the boundaries of a normal block just fine - i.e. a 2x1 block

can someone tell me why even though i cancelled the event players can move the blocks in the gui

[hybrid spoke]

well, first of all, dont compare inventories by their name.
second, have you registered the listener? make sure that its actually the name. debug

[peak depot]

but can you give negative levitation?

[hybrid spoke]

isnt levitation the one where you fall smoother?

[peak depot]

slowfalling

that might be it

[peak depot]

levitation is that what shulker give

[quaint mantle]

well how else can i make sure then their name?

May someone help me to understand better how practice servers work for example those arenas they will be objects which will be added to HashMap which will store available ones but like i then need tons of arenas in singular world like idk if i have 50 players i would need minimum of 25 arenas for example ?

[hybrid spoke]

usually you load them dynamically instead of having a set set of arenas

[mellow pebble]

what do you mean dynamically i mean I would personally make arena manager which would load all possible arenas into HashMap which will take Name and Arena as key and value and basically if it is available it will be in that HashMap if not it will not be added but once game in that arena is finished it would be cleared (since blocks placed would be tracked and removed on game finish) and then added back to available arenas

[hybrid spoke]

with dynamically i mean that you have a schematic of the map and generate a new arena once a player needs it

and once he's done it will get removed

with that you can also keep a few preloaded so that they will be available sooner without having to wait until it finished generating

[mellow pebble]

well i never worked with schematics like that to dynamically load them somewhere in worlds

[mellow pebble]

well how much could it take for map like 100x50 to load 🤷🏻‍♂️

[hybrid spoke]

within a few ticks i assume

using fawe, flawless

but depends on your hardware

[mellow pebble]

ill check it out but i always had problems using FAWE on legacy for some reason

[hybrid spoke]

you can come back and ask for help with fawe if you cant manage to do it

[mellow pebble]

but see in schematic how can i know location of map so i can track player spawnpoints etc

[hybrid spoke]

you would have a setup of the map which will be loaded for every generation

for example you build the map at 0,0,0. you can just generate the new one in his own world at the given coords

with that all the location points you might have set stay the same

just the world changes

[mellow pebble]

ill have to see with that really

[dawn flower]

    @EventHandler
    public void onJoin(PlayerJoinEvent e) {
        Bukkit.getScheduler().runTaskLater(PacketInterceptor.plugin, () -> {
            PacketInterceptor.injectPlayer(e.getPlayer());
        }, 1L);
    }```

```java
    public static void injectPlayer(Player player) {
        Channel channel = getChannel(player);
        Interceptor interceptor = (Interceptor) channel.pipeline().get(handlerName);
        if (interceptor == null) {
            try {
                channel.pipeline().addBefore("packet_handler", handlerName, new Interceptor());
            } catch (NoSuchElementException e) {
                e.printStackTrace();
            }
            uninjectedChannels.remove(channel);
        }
    }```

this throws
```[17:56:56 WARN]: java.util.NoSuchElementException: packet_handler```
which makes no sense because it only does it if i try to join but if i was already in the server and i reload the server (it does this onEnable)
            for (Player player : plugin.getServer().getOnlinePlayers())
                injectPlayer(player);

it works normally

[hybrid spoke]

you really dont want to set up 25 arenas and have your players wait until someone is done

[mellow pebble]

yeah if im going to make that i will make 70 arenas or so and thats it

[hybrid spoke]

yeah well no. i mean its up to you, but thats the worst you could do

Hello, what is the equivalent for AbstractCriterionTriggerInstance in 1.20.4 in nms?

[formal egret]

Im starting a new plugin strictly for versions 1.13-current and I am wondering which Java version is best for programming in? I previously used Java 8. Should I stick with Java 8 or move to Java 17?

[hybrid spoke]

java 8, because using a higher java version will make your plugin unavailable for <1.16

[cinder abyss]

to support 1.17 and before, you need to compile your plugin for java 8

but you can dev with java 17

[hybrid spoke]

at least if you use features of higher java versions

you can also use java 17 and only use java 8 features, luckily java is backwards compatible

[cinder abyss]

using java 8 will using spigot-api 1.16.5+ in you code will throw an error, so you can use java 17 to be more confortable

Hey I have the following hashmap

Hashtable<Integer, Material> materialHashMap = new Hashtable();
            Iterator<Material> materials = Arrays.stream(values()).iterator();
            int i = 0;

            while(materialHashMap.size() < 256 && materials.hasNext()) {
                Material material = materials.next();
                if (material.isSolid() && !material.hasGravity() && !material.isInteractable() && !material.equals(FARMLAND) && !this.isTagged(tagBlacklist, material)) {

                    ++i;
                }
            }

Im trying to get the block id aka the integer in the hashmap
getKey() doesnt seem to work any suggestions would be appreciated

blockID = (materialHashMap.getKey(((Player)sender).getWorld().getBlockAt(x, 256 - y, 16 * row + z))).ordinal();

[lost matrix]

Why dont you use an actual java HashMap?
And why are you mapping from int to Material if you want to get the int by Material.
Why not map the other way around?

[noble olive]

Been using a hashtable since the start didn't conisder using a hashmap tbf might re do the entire thing with it if I must
I had some other functionalities where I needed to transform file bytes to int and from int to Material now im trying to reverse this process but im struggling a little with getting from Material to int part

[lost matrix]

Use two maps and map in both directions, or use guavas BiMap which internally maps into both directions.

(What I did is a double click over an equal item that was in my inventory)

[lost matrix]

Cancel the InventoryClickEvent

[eternal oxide]

Cancel inventory drag event

[worthy yarrow]

Cancel all the inventory related events 😄

When it comes to separation of concerns, say you’ve got an event listener that has multiple functions based on properties of said event, would it be better to just split functions into helper methods or perhaps multiple instances of the event listener?

[lost matrix]

Cancelling the InventoryClickEvent will always prevent the InventoryDragEvent from being fired

[eternal oxide]

it doesn't

[worthy yarrow]

As in a sort of manager I suppose you could say that dictates the functionality of the event when it occurs, based on some properties

Hello! How can I get an item which was added to the inventory by /give command? I can't find correct event

InventoryClickEvent, InventoryMoveItemEvent, InventoryPickupItemEvent don't work

[hazy parrot]

what is this language ? scala ?

[worthy yarrow]

I don't think there's any method for this. You'll have to essentially recreate whatever item you're looking for and implement detections for when that item is added to a player inventory @hot dune

[rough ibex]

I think so yes

[hot dune]

well rip

[rough ibex]

= {} is a giveaway

• def

[worthy yarrow]

Is it a custom item or vanilla?

[hot dune]

item that given by vanilla give command, so I think it's vanilla one xd

[worthy yarrow]

Well then depending on how many items you're trying to detect, pretty simple

[hot dune]

I try to check if the item is an equipment (e.g. sword or tool), so they are always are one in the stack

I just write /give @p minecraft:diamond_axe and I need to get this item and then change it's lore and other stuff

[worthy yarrow]

Mmmm

I'd rather just do a custom command that gives an item, then within that class you can define the items lore/meta/etc through pdc meaning you create an itemstack object that has persistent data. This itemstack now holds data that will persist over server restarts and what not

[hot dune]

okay, will try

anyway one day I gonna rewrite some vanilla commands xd

[worthy yarrow]

I'm 99% sure there's no method to access the vanilla commands... meaning you can't really do anything without recreating the command yourself

[acoustic pendant]

Okay so i've done this to get the following string:
effect[FIRE_RESISTANCE,1]

And i was wondering if this is the correct way or maybe other more optimized would work

[worthy yarrow]

https://paste.md-5.net/emijeqicov.java Here's an example you can use, it's very simple and functions as a way to create a "new" itemstack (chickenpet) each time the command is ran, meaning every single chicken pet acquired with said command is an individual as in it's own persistent data

[acoustic pendant]

I was talking about the split xd

[river oracle]

don't make use of split this can be done in one iteration with a for loop

you have a couple "tokens" here first the [ token which is some sort of arguments then , which denotes the start of a new argument and ] which denotes the end of an argument

[lost matrix]

Is this for loading an effect from a config?

[acoustic pendant]

yea

[river oracle]

if you use a for loop you can use this to your advantage if you want to go crazy and have much more advanced tokens in the future you can use an abstract syntax tree

[river oracle]

ngl bukkits serializations are almost never as ideal as they could be but changing them is also problematic in of itself

[worthy yarrow]

Back when potionEffect.getFromName (or wtv it was) wasn't deprecated D:

[lost matrix]

PotionEffect effect = ...;
FileConfiguration config = ...;

// Saving effect:
config.set("some.effect", effect);

// Loading effect
PotionEffect loaded = config.getObject("some.effect", PotionEffect.class);

[river oracle]

saying use the serializable isn't really as cool as it sounds

[young knoll]

Well you can save the key

[river oracle]

granted their serialization method isn't Ideal either

[young knoll]

But you still need other data

[lost matrix]

But randomly splitting a String and hoping for the best sounds more hip and cool?

[young knoll]

I guess you could do key,duration,level

or
type: type
duration: duration
level: level

[acoustic pendant]

lol

Either that or you use dependency injection (DI) to hand them over. In that case you can use a keyholder class you create a single instance of

My method to see if an inventory has space for a list of items is somehow modifying the item I'm checking. Can anyone see what is causing this and why? https://pastes.dev/QpONvo5UhR

edit: I still have no idea why this is happening but chatgpt said the itemstack is getting split in partial stacks to try and fit them in the inventory and for some reason that modifies the original instance

[kindred sentinel]

btw it didn't solve the problem, "No suitable driver found for jdbc"

[glad prawn]

fine for me

[smoky anchor]

My guess would be that Arrays.copyOf(inventory.getContents(), 36) does not do what you hope it does
it will not copy the objects

[sand spire]

those objects is the original inventory, only the items I'm trying to add get modified. I think it's because of this line
Map<Integer, ItemStack> map = fakeInventory.addItem(itemStackList.toArray(new ItemStack[0]));

actually it sounds like this line on the wiki is explaining my exact problem now I'm just confused if it's a bug or a feature

I guess I will just do this to solve it

List<ItemStack> itemsToAdd = new ArrayList<>();
        for (ItemStack itemStack : itemStackList) {
            itemsToAdd.add(new ItemStack(itemStack));
        }```

or stream idk what is better

Why is it, that when I do setItem in an gui it only updates when the amount is greater than one?

[lost matrix]

What version are you on?

[pliant topaz]

1.21 latest build

read about it in forums too, is this some kind of known bug?

[lost matrix]

Setting the amount to 0 should remove the ItemStack iirc. In older versions it resulted in ghost items.

hey, im getting this error whenever whenever i try to log into my server (it seems to be to do with tab prefixes) and im not too sure what im meant to do to fix it in my code, cus the prefix its trying to load is under 16 chrs

[pliant topaz]

i see, so basically having non-stackables refreshed upon using setItem is impossible, right?

[lost matrix]

Player names are hard capped at 16 characters. Anything more crashes the client.

[lost matrix]

Not sure what that means

[lusty flax]

but arent team prefixes meant to have a 16 chr limit too?

[pliant topaz]

basically that when I use setItem and it is a not stackable (the item) that it won't update the inventory and result in weird behaviour

[lost matrix]

I dont... each Material currently has a maximum stack size. And you cant create stacks with bigger stacks than their current maximum.

[pliant topaz]

ik

[sand spire]

It would be easier to understand the issue if you show some code

[pliant topaz]

okay, wait

player.setItemOnCursor(new ItemStack(Material.AIR, 1));```
activeInventory being the current opened inventory for said player and the item on the cursor being a netherite pickaxe with some metadata

when this happens it results in lots of weird behaviour and inventory bugs/ghost items

[lost matrix]

Ah, the behavior in this also depends on the cancelled state of the event. Its quite tricky.

[pliant topaz]

when cancelled it just doesnt do anything, when not cancelled the weird behaviour occurs

I guess it rlly all just comes down to testing a whole lot of stuff and seeing if it works, am I right?

[inner mulch]

Poor smile getting blasted with 19 questions at once

[echo basalt]

Pre-1.13 16 is the limit for both prefixes and suffixes. Now the limit is around 1024 iirc

[echo basalt]

You can hack in with reflections a bit

[lost matrix]

Or you wait for 1.20.5 🙂

[kindred sentinel]

OHhh

[echo basalt]

Exactly

[kindred sentinel]

It works! Thanks!

What event is this?

[cinder abyss]

Hello, how can I change the name of displayed on a villager trade popup but without modifying villager's name?

[agile quiver]

Hello do you know how to lock the head movement of the player like for a cinematic?

[cinder abyss]

modifying that

[lost matrix]

Set him in spectator mode and let him spectate an armorstand or other entity.
Then move the spectated entity around while keeping the eyes on a focal point.
