[proper cobalt]

HEADS never contains any values

[cinder abyss]

no because I'll use custom model data, so I need to use an ItemDisplay

[proper cobalt]

is bukkit yml busted

[chrome beacon]

contact-gui-letters is not a list

So you can't use getStringList on it

[proper cobalt]

oh what is it

just a section?

[chrome beacon]

yes

[proper cobalt]

                for (final String key : MESSENGER_FILE.getConfigurationSection("texts.contact-gui-letters").getKeys(false)) {
                    HEADS.put(key, MESSENGER_FILE.getString("texts.contact-gui-letters." + key));
                }

[chrome beacon]

You can loop getKeys(false)

[proper cobalt]

so like this

aight

[chrome beacon]

yes

[eternal oxide]

using ItemDisplay the one you want is alwasy going to be a positive Y distance

from the broken blocks location

[cinder abyss]

what do you mean ?

ooh okay

and what about the X and Z ?

[eternal oxide]

the display you want should always be +0.4 on all axis from the broken block

[cinder abyss]

so I substract -0.4 ?

[eternal oxide]

block location + 0.4

[cinder abyss]

here are the locations for this configuration

[eternal oxide]

shoudl give you the ItemDisplay location

[proper cobalt]

ye that worked thanks Olivo

[cinder abyss]

when breaking the top left one, it breaks the bottom right one

[cinder abyss]

okay thanks

[eternal oxide]

it may be +0.5 but try it and see

[cinder abyss]

okay thanks

[eternal oxide]

Block location is based on its corner, ItemDisplays are centered

[cinder abyss]

I see

[eternal oxide]

so shoudl alway be +0.4 or +0.5 to find the correct display

[cinder abyss]

so I need to make it's position like a block/BlockDisplay

[eternal oxide]

block.getWorld().getNearbyEntities(block.getLocation().add(0.5,0.5,0.5) ,0.1 ,0.1, 0.1)

you can also predicate for an ItemDisplay too, then you'll only get teh one

[young knoll]

You can also tag your item displays with some pdc

To be extra safe

[stuck oar]

can i make like huge itemdisplays just in spigot

[cinder abyss]

I already done it

[cinder abyss]

okay thanks

[blazing ocean]

yeah just change the scale

[stuck oar]

rn im using armorstands is ther another way to do itemdisplays

[young knoll]

Item displays

That’s literally the entity name

[stuck oar]

oh ye just found it on the api lol

thanks

[proper cobalt]

why doesnt it work

the inventory stays open

[wet breach]

believe you can't force close the player inventory

since its always open

[proper cobalt]

no its like a custom gui

chestgui from Inventory framework

[worldly ingot]

They probably have some listeners that prevent inventory closing

[river oracle]

Should work if it's open is it really open when you call the close?

Is it flickering?

[proper cobalt]

nah they dont

[proper cobalt]

literally nothing

u can close it normally if u want

but when u call that method

nothing

[river oracle]

What version?

[eternal oxide]

are you calling close in a click event?

[proper cobalt]

1.19.4

[river oracle]

You're doing something wrong here

[proper cobalt]

yes

[river oracle]

Ohppee

[proper cobalt]

InventoryClickEvent consumer

[eternal oxide]

do it 1 tick later

[proper cobalt]

aight thanks g

[proper cobalt]

wheredd u find this

link that

[eternal oxide]

in the javadoc for the click event

[remote swallow]

?jd-s

[proper cobalt]

ye the inv closed

nice one

[dawn plover]

Hey hey, i updated my spigot api for my plugin from 20.1 to 21.3
in this update, i noticed that Enchantment.DURABILITY seems to not be a thing anymore. and it now is Enchantment.UNBREAKING. But i currently found out by breaking my code,
However, i was wondering if there is a changelog where i can find everything in a nice list just like mojangs changelog?

[proper cobalt]

is it possible to make itemstacks amount like 1, but like actually show the number 1

[dawn plover]

no

[proper cobalt]

swear ive seen it before

[dawn plover]

but that probably is a mod and not a plugin

[proper cobalt]

na obv not

[dawn plover]

plugin is only server sided, while that number is client sided

[proper cobalt]

kk

[dawn plover]

The visual number i mean

not the quantity ofcourse

[river oracle]

Resource pack probably could do that

Just retexture every item with a 1 kekw

[dawn plover]

if you are going to do that, i would just retrexture the base model to have a second layer that contains the 1 if i where you. saves a lot time since you dont have to texture them all individually

and besides, its also pretty much the only way to do that for the 3d items

But before you do that, If yea want the 1, you can also think in alternative ways. Is there for example an empty item slot nearby (below, or on the right for example)
What you can do is in that itemslot, place an item that you retexture to be the one, and make the texture with such an offset that it apears to be 1 slot highter / 1 slot to the left

a good example are these locks and checkmarks for example. Those are not actually part of the item below it, but instead are in a slot above it

[quaint mantle]

hey, i made a new project on IntelliJ but instead of showing life com.fourseven.skyblock like a package it shows as separated directorys, also i can't create packages, i just can create directories

[remote swallow]

Use a build system. And reload it

[quaint mantle]

wdym?

like adding maven?

[remote swallow]

Maven or gradle

[quaint mantle]

i thought abt that, but i wasn't that sure, it does work

ty

so i'm doing a plugin recode and copied the pom.xml, reloaded IntelliJ and now i have my proyect skyblock-recode like this

sorry if it's a stupid/easy-to-solve question

[north nova]

ur module name is different from directory

[quaint mantle]

I know, how can i un-do that?

I just copied the proyect i want to recorde pom.xml but that happened

[north nova]

u can move things where they need to be lol

[quaint mantle]

My module name turned into the other plugin name

and the directories i created for the recode are now inside the module

[chrome beacon]

See the developer notes on the release post

It usually gives a brief overview on the major changes

[cinder abyss]

Hello, what is the wiki to see how is made the packet for PacketType.Play.Server.ENTITY_DESTROY ? (I want to get the entity involved)

[quaint mantle]

https://wiki.vg/Protocol

[cinder abyss]

thanks

[quaint mantle]

np

also

https://mappings.dev

wiki.vg has mojang mappings, you can search spigot mappings in mappings.dev

[chrome beacon]

Wiki vg doesn't really use any specific mappings

[quaint mantle]

Well yeah you right, i forgot it uses packet ids

i'm sorry

[cinder abyss]

okay thanks

[quaint mantle]

no problem 😉

[waxen acorn]

Did Attribute constants got renamed in latest API? My plugin code seems to be broken after the update to 1.21.3

[pliant topaz]

seems like the pom created (in its sense missing) directories/modules for it. Personally I redo the pom manually in such a case just to update everything and often its not too much work. I would just move/rename your packages to desires place/name, update the pom accordingly and call it a day :)

[chrome beacon]

A couple of things got renamed

but your old plugin jar should continue to work

[quaint mantle]

Yeah, but it results i forgot the directory "java" so i wasn't able to do a lot of things, then reloaded maven and all good

[chrome beacon]

Or if you're trying to compile against the newer version you'll need to change the code

[waxen acorn]

I know the server will do some ASM magic for me. Uh I'll have to face the tough renames in code...

tysm

[quaint mantle]

How do patches work?

Maybe a idiot question ik 😭

But i never understood them

[chrome beacon]

A patch usually just stores a diff

Or a difference between two files

[pliant topaz]

afaik basically do what the name says, patch some stuff over other stuff, like patching a road and putting new stuff ontop of old

olivo said it better

[quaint mantle]

But what do they exactly do?

[nova notch]

yo, offtopic but this looks really good

[chrome beacon]

On their own nothing much, but they're used to apply the changes they contain on to another file

Basically turning the old file in to the new file you want

A patched file if you will

[quaint mantle]

Ohhhh like they modify the file

[chrome beacon]

For example Spigot uses patches to take the decompiled code and apply their changes on top

[quaint mantle]

Ohh i see

[pliant topaz]

Microsoft restricts others of constributing modified software of them, so by having patches the original source code is used as a base and only modified at the users end, basically a way of altering software without breaking their policy

[chrome beacon]

Legal gray zone

[quaint mantle]

But why do forks use that? can't they just grab the code in java and manually code it? (sorry if im so wrong)

[pliant topaz]

nope

Because theres still some copyrighted code from microsoft in there

[chrome beacon]

You cannot redistribute Mojangs code

So you just distribute the changes

[quaint mantle]

Oh yeah i totally forgot about that

[waxen acorn]

changes does not work without original code

they are just patches

[quaint mantle]

But is it possible? maybe if i want to do a private fork

[chrome beacon]

Yes but you're not distributing the original

[pliant topaz]

which is what i said, they use the original source code as a base which is then modified

[quaint mantle]

Afaik you can use microsoft code just for you, right?

[waxen acorn]

True as buildtools download it from Mojang server, which is legal

[chrome beacon]

Yes but just a bad idea

[quaint mantle]

Oh alright

[pliant topaz]

kinda funny how it can get really messy easily

[waxen acorn]

that is what Hypixel does

they have Hygot

[chrome beacon]

Doubt

[quaint mantle]

Yeah, that's why i thought abt that

[pliant topaz]

for example, paper is patching spigot which is patching bukkit which is patching the original source

[chrome beacon]

No need to go that route

[waxen acorn]

yeah that is a chain....

[chrome beacon]

You can just use the patch tooling on your private fork too

[quaint mantle]

Yeah LMAO

[remote swallow]

The chain is infinite

It's all forks, always has been

[waxen acorn]

yeah as well as your fork users could access your patches according to GPL license?

[quaint mantle]

And it will ever be

[waxen acorn]

it is interesting to have GPL on Bukkit

it totally does not work with Mojang code but still exists so what is the meaning of it

just protect Bukkit itself?

[quaint mantle]

I wonder what's CraftBukkit creator doing right now

[waxen acorn]

I had no interest on these legal issues as current dev env had solved this for us but interesting to learn why

[chrome beacon]

Bukkit is just the API so it works fine

[pliant topaz]

until the number climbs to a point, where we have a 10 adic numbers eventually representing 0 ;--;

[chrome beacon]

CraftBukkit is a bit different

[waxen acorn]

dinnerbone still works for Mojang and idk where is EvilSeph

[quaint mantle]

Bukkit is API CraftBukkit is server

[quaint mantle]

yeah i wonder bout evilseph

[waxen acorn]

yeah so is GPL applicable on CB code?

I remembered that CB uses LGPL

[quaint mantle]

awww

i'm so glad evilseph and md_5 didn't forget about the project after EULA update

[pliant topaz]

yea

[quaint mantle]

yeah

[pliant topaz]

then we wouldnt have spigot, paper, purpur, pandaspigot and all the other forks out there all depending on each other

[waxen acorn]

yeah Spigot is where the modern MC server plugin modding begins

[pliant topaz]

altough spigot isnt used much anymore its one really important piece of software we have to keep going

[quaint mantle]

If spigot is discontinued every fork is too

[pliant topaz]

basically

[waxen acorn]

will not but will lack of a strong dev power

[kind hatch]

Well... not if paper hard forks and becomes their own thing.

[pliant topaz]

i know paper had some plans on hardforking, but thats not really a good option, spigot is really the backbone of everything

[waxen acorn]

so Spigot is still important for everyone

[quaint mantle]

Minecraft servers would not be that famous without craftbukkit

[waxen acorn]

yeah really not good as devs will have pain on incompatible changes

but what incompatible change will happen if hardfork really happens?

will all Deprecated Spigot methods in Paper got removed?

[quaint mantle]

in the case craftbukkit and spigot got discontinued on EULAs changes, servers would still in 1.7.10, servers would not be popular or they would be so many forks out there

[kind hatch]

Probably :kek:

[waxen acorn]

I don't like incompatible class change errors, really painful haha

[pliant topaz]

Sometimes I think back to mojangs 'Modding API' which has never seen the daylight because 'theres so many community option available so an official api is not necessary but then on the other hand, just these immense constributions like spigot, forge, paper, bukkit, fabric etc etc, im kind of glad they never did it, especially as we're now basically capable of doing what their api would allow us to without their api

[cinder abyss]

Hello, I want to reproduce EntityRemoveEvent for before 1.20.4 by using Protocollib
Everything is working except the fact that the packet is sent after the entity was deleted, so how can I get the entity before it's deleted ?

[quaint mantle]

i recommend using last spigot version

[cinder abyss]

I want to support a bit of other version

1.20.4 is REALLY young

[quaint mantle]

i mean you can use viaversion

[waxen acorn]

just give it a try first, if it work then you can do backports

[quaint mantle]

and viabackwards

[cinder abyss]

I already gave it a try

[waxen acorn]

so it works on 1.20.6 but not on 1.20.4?

[cinder abyss]

I want to support more, but EntityRemoveEvent doesn't exist before

[cinder abyss]

it works on 1.20.4 because EntityRemoveEvent already existed

[pliant topaz]

then you may have to implement it yourself

[waxen acorn]

have you ever checked CraftBukkit source?

[cinder abyss]

but I want to support before 1.20.4

[quaint mantle]

what's entityremoveevent

[spice cove]

i can post a paper plugin as a resource under spigot right?

[quaint mantle]

imma go read javadocs

[quaint mantle]

no

[cinder abyss]

I need to do some nms tricks ?

[spice cove]

where would it be posted

[waxen acorn]

if it is Paper-only then go hangar

[quaint mantle]

?whereami

[undone axle]

https://cdn.discordapp.com/attachments/864180468680360027/944415049462714469/whereami.mp4

[cinder abyss]

it's when a Entity die, instead of a Living one for EntityLivingDeath or smth like that

"Called when an Entity is removed.
This event should only be used for monitoring. The result of modifying the entity during or after this event is unspecified. This event is not called for a org. bukkit. entity. Player."

[spice cove]

what makes it paper only

[pliant topaz]

you can look at the patches applied in the newest version and try to recreate what theyve done in your desired version

[pliant topaz]

using any paper-only methods

[waxen acorn]

if you have only paper-plugin.yml as the plugin descriptor then it is

[quaint mantle]

why not to use EntityDeathEvent?

[waxen acorn]

that is how I define Paper-only plugins

[spice cove]

cuz i've seen paper plugins posted as a resource

[kind hatch]

Why not use the EntityDeathEvent

[quaint mantle]

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

[cinder abyss]

Because my entity is a ItemDisplay

[quaint mantle]

that's an entity

[cinder abyss]

it's not a LivingEntity

[kind hatch]

It's not a living entity

[waxen acorn]

They may just have better functionality on Paper as they could support Spigot for basic option

[quaint mantle]

yeah right

[cinder abyss]

patches are files or directly in code ?

[quaint mantle]

saw it, sorry

[waxen acorn]

files containing patch code

[pliant topaz]

diff files, they tell you what was removed, added etx

[cinder abyss]

interesting

[waxen acorn]

But it will be tough to read patches instead of patched code

[cinder abyss]

where can I find them/patched code (so what I need basically) ?

[waxen acorn]

You can open Spigot-Server as a maven project in your buildtools work dir directly

then just search for references to what you want to see then you'll found how it works

[wet breach]

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

[quaint mantle]

Update spigot

[spice cove]

so i wanna post my plugins on spigot, and i've heard paper has more things and most servers are paper, spigot works in them too. should i use paper or spigot?

[quaint mantle]

look at jd

[cinder abyss]

#help-development message 😌

[waxen acorn]

a really common issue. That is up to you

[spice cove]

what things does paper have that spigot doesn't

is it anything that is used often

[waxen acorn]

Actually my preference is Paper as I'm a minigame dev and Paper acts actually better on minigames

[quaint mantle]

if you wanna post your plugins @ spigot mc page, you need to use spigot api

[kind hatch]

Paper has stuff that spigot doesn't have. So if you utilize those things that paper offers, then your plugin will not work on spigot.

[wet breach]

You need to check some kind of hit or health event

[waxen acorn]

just more API for plugin devs and better performance for users

[cinder abyss]

seems interesting

[wet breach]

When health reaches 0 run your custom event

[echo basalt]

EntityRemoveFromWorldEvent

type shit

[quaint mantle]

What's the difference between 20.0 TPS and *20.0 TPS

[cinder abyss]

there is health for ItemDisplay ?

[north nova]

*20 TPS has a star

[kind hatch]

Approximation

[wet breach]

All entities have health

[echo basalt]

LivingEntity be like

[wet breach]

Items have like .5 if i remember right

[cinder abyss]

yeah but didn't though it was monitored

[waxen acorn]

equals to entity instanceof Damageable

[echo basalt]

non-living entities don't have health

🙄

[quaint mantle]

why does it show 20.0 TPS and *20 tps?

[echo basalt]

they're either dead or alive

[waxen acorn]

so if it is damageable it should have

[cinder abyss]

THIS IS PAPER AAAAHHH 🗣️ 🔥

[wet breach]

They technically do, that is why they can take damage sometimes and instantly die

[waxen acorn]

You can also implement the event specifically in different modules

[echo basalt]

eh

[waxen acorn]

that is common structure for plugin dev

[echo basalt]

Not properly

[quaint mantle]

create event by yourself ¯_(ツ)_/¯

[echo basalt]

They can "die" but they don't track health

Their damage method insta-kills them

[cinder abyss]

but DamageEvent works on them then ?

[waxen acorn]

techinally right but is there a value tracking health?

[quaint mantle]

afaik vehicles have health, and they aren't living entities

[echo basalt]

frosty don't try to debate over this imma just copy-paste the entire nms entity class and whoop your ass

[kind hatch]

Imagine if it was pushed upstream. :3

[cinder abyss]

imagine :O

[waxen acorn]

then see Paper source to know how it works

and implement by yourself, it seems to be tough but really a working way

[cinder abyss]

ik ik

but maybe if I can use DamageEvent that'll be better

[waxen acorn]

So I just wondering if API backports is possible on Spigot?

[quaint mantle]

Bro just do it by yourself

[waxen acorn]

we can just imagine as current API does not cared this situtation....

[cinder abyss]

I'll just try, it costs nothing

[kind hatch]

Wdym?

[wet breach]

Items do have health. Nbt tag says otherwise

Items have a health of 5 and reduces to 0

[echo basalt]

Items have health and they happen to be non-living, this doesn't mean that every non-living entity has health too

For example, marker armorstands

Or area of effect clouds

[cinder abyss]

pretty sad

[sly topaz]

you mean like, spigot accepting API backports? That's a no

[wet breach]

Armorstands have health too. Just if they are invisible they are invulnerable

[cinder abyss]

I monitored 4 killed rabbits

[sly topaz]

you are free to fork Spigot and backport API there though

[cinder abyss]

but not my ItemDisplay

[echo basalt]

Marker armorstands are separate

ItemDisplays don't have health

This is a "marker"

[waxen acorn]

yes so I was just imagining

[sly topaz]

ideally, you use something like Ignite so you could backport API between multiple versions with a single plugin/coremod

[waxen acorn]

Whoah, Mixins on Bukkit?

really hackful but useful on private use, not suitable for distrubted plugins

as I don't think will it work with hybrids as I'm a cross platform dev haha

[wet breach]

But they do have an invulnerable tag lol. But you are right it doesnt appear they have health from the docs.

I would have to look at mc code to see exactly what it does though

[sly topaz]

there's only one hybrid, and that's spongeforge

[echo basalt]

There's also minecarts

Which are non-living but get hurt

[sly topaz]

would barely call that an hybrid considering it was built from the ground up to be compatible with forge

anything else is just a disaster

there's solutions like architectury but it doesn't support bukkit so it is all the same

[cinder abyss]

hum

I've got the patch that I need

but I don't really see what to do with it

should I just loop every tick for killed ItemDisplay entities ?

and check with the old list, and get the killed entity in the old list basically

[sly topaz]

I'd try weak references to the entities

[sly topaz]

just caught up with the whole convo, this should work, more or less

[quaint mantle]

we should have a command like ?downgrade that answers with the md_5 answer to a thread

[sly topaz]

eh, those commands are somewhat aggressive, ideally you just answer their question with a warning that it is unsupported so they'll have to figure stuff out

most if not all of the support threads are for older versions too so it is hard to expect people not asking questions about older versions

discord killed any kind of searchability issues with spigot/paper had

[waxen acorn]

maybe you'll need to see where fires EntityRemoveEvent

[sly topaz]

it's useless to check that kind of thing, since it often hooks into inaccessible code from a plugin

[waxen acorn]

yes maybe tough in that situtation but will be good as a start to understand it

[cinder abyss]

I already done that, it's unreachable from my plugin as said

[waxen acorn]

so it is time to find workarounds

uh really a useless sentence

[cinder abyss]

👍

[waxen acorn]

a good idea for trial, but need optimization

[cinder abyss]

sure

[sly topaz]

-# just hook into the method with CGLib

[cinder abyss]

?

oh

[sly topaz]

I was kidding

runtime bytecode manipulation go brr

[waxen acorn]

their readme said it no longer work well in newer JDK

[cinder abyss]

would have been hell anyway

[waxen acorn]

particularly 17+

[sly topaz]

ah, that's a shame

[waxen acorn]

they had suggest ByteBuddy as fallback haha

[sly topaz]

it made hooking into methods you didn't have access to really easy

bytebuddy is fine, but it isn't as easy

[waxen acorn]

yeah I've used it before but its API confuses me

[sly topaz]

still, if I wanted to do some serious backporting of functionality, I would probably go that route anyway

[waxen acorn]

for private use it is ok but still not good for public plugins

[sly topaz]

eh, it is fine

there's a couple of plugins which do it

as long as it is done for versions that aren't updated anymore that is

since behavior isn't going to change

[waxen acorn]

then I think they have some good way to do so if they really implemented something we can't imagine

[sly topaz]

anyhow, I gotta keep reading this scala book

I can't concentrate more than 5 minutes, my brain is broken

[junior geyser]

Did they change the head rotation packet for 1.21.3?

[quaint mantle]

probably

i'm glad most of ppl r updating

[unborn goblet]

Does anyone know why PersistentDataContainers are not saving any data to the player?

bro this old username

[nova notch]

same and they really want you to pay like $10 to change it

[sly topaz]

what

how is it not saving data, like, you restart the server and it isn't there?

[unborn goblet]

Mb, it just doesnt save at all

[sly topaz]

that just leaves me more confused lol

when you set into the PDC, it should save the data to its respective playerdata

though I don't know if it does so as soon as you write it, or it is done in batches to avoid doing too much IO

the way minecraft handles saves is rather (unfortunately) undocumented

[unborn goblet]

Is there a method I have to call to initialize the change maybe? 😭

[sly topaz]

/save probably works? lol

or was it /world-save, something -save

it should do that automatically, but maybe you're closing the server before it has the chance to

though if you close it the proper way, it should definitely save before close

[unborn goblet]

Is it possible to save pmc and get those new changes in the same method?

[sly topaz]

how are you using PDC

because what you're saying isn't making sense

[unborn goblet]

Ah I’ll just send my spaghetti code which isnt working

https://pastebin.com/VJNx6teZ

Alright so I’ll briefly explain what I’m doing to test this.

I’m adding a player using /trust add (player) but when I then do /trust list it shows an empty list

[unborn goblet]

More context - this is part of a command class 😭

[sly topaz]

I mean, your list command only seems to be sending whether the key exists or not, unless you've cut up the logic that actually sends the contents of the list

I gotta ask even though unrelated to your question, why in the lord's name is there an atomic reference there

[unborn goblet]

That might be dead code holup

[unborn goblet]

Nvm it’s in a foreach loop of a list of all the player’s online

[sly topaz]

what does that have to do with an atomic reference

did you use it so IDE wouldn't complain about the perceived lifetime of the variable?

you can just use an array with a single element if that's the case

an atomic reference however has thread-safe checks which are overkill for whatever you're doing there

[worldly ice]

or just use a regular for-loop

[unborn goblet]

It was a suggestion from Intellij yes 😭

[unborn goblet]

Not sure exactly 😭

[unborn goblet]

Oh alrighty

[worldly ice]

String playerName = null;
for (Entity entity : worldEntities) {
  if (entity.getName().equals(strings[1])) {
    playerName = entity.getName();
    break;
  }
}

you should just be able to do that

no reason to use a foreach there

[unborn goblet]

Ohh ty

[worldly ice]

as for you issue PersistentDataContainer#get might return a copy of the list

so you'd have to set it back after you mutate the list

and i will also say your (im assuming) limit of 30 trusted players is done in a very convoluted way

just check if the length of the list is >= 30 or something

if it is don't add the player

[unborn goblet]

Ohh ik dw 😭 I just for some reason didnt want to set the list size to something like 255 for some odd reason

I’ll change that later

[worldly ice]

lists can be any size?

[unborn goblet]

Ohh alrighty

[worldly ice]

they allocate memory dynamically

[unborn goblet]

I’ll try that when I can

[unborn goblet]

Using list.add on the list gotten from pdc.get throws an UnsupportedOperationException

[worldly ice]

oh i see why

its because #get returns an immutable view of the list

changes to the original list are reflected but you aren't able to make any modifications yourself

[unborn goblet]

For that I would use pdc.set?

[worldly ice]

create a new ArrayList<>(trustedPlayers)

modify that list

set the pdc back to that list you just created

[unborn goblet]

Ok tysm 😭

I’ll try this out once I can but thank you regardless !

[worldly ice]

yeah np! if you encounter any more issues feel free to ask again

[unborn goblet]

Ty !🙏

[quaint mantle]

what's the best way y'all know to make a singleton

[rough ibex]

Enum

Effective java

Item 3

// Enum singleton - the preferred approach
public enum Elvis {
INSTANCE;
public void leaveTheBuilding() { ... }
}

This approach is similar to the public field approach, but it is more concise,
provides the serialization machinery for free, and provides an ironclad guarantee
against multiple instantiation, even in the face of sophisticated serialization or
reflection attacks. This approach may feel a bit unnatural, but a single-element
enum type is often the best way to implement a singleton. Note that you can’t
use this approach if your singleton must extend a superclass other than Enum
(though you can declare an enum to implement interfaces)

[sly topaz]

please don't do this

the benefits of this over just doing a normal singleton with a static final class are not worth the unreadability of that code, the intent isn't clear at all here

[vagrant stratus]

@chrome beacon
I saw this re-linked in general
https://hypixel.net/threads/dev-blog-6-keeping-up-with-the-masses.2251554/
We added an ID to the NBT compound, then when we first compare items, if they are equal we sync up their IDs and we know for certain that they’re the same, we also track the parent of each NBT Tag, so when something changes within it we change the ID and thus the process begins again, this makes it much faster for us to do just as many comparisons.

How possible do you think this would be for the item monitoring plugin? There'd definitely have to be a bunch of checks (and NBT calls, obviously) so that vanilla functions as expected, but I think that it would make things easier?

[quaint mantle]

:)

[chrome beacon]

Hm what does that have to do with me?

I've never said they don't mess with nms

What I did say is that they most likely still use the patch tooling

[vagrant stratus]

recreating it with spigot & NMS calls. Think that's relatively better than maintaining a completely separate list of items & stuff

[vagrant stratus]

Couldn't modify spigot directly so there'd be some pain to it but if it would be better done this way then it could be worth writing all the utilities and listeners needed

[smoky anchor]

well it looks like you're not setting the Lore tag if it does not exist

Are you just modifying vanilla code ?
With MCP or something ?

Well I wish you the best of luck with whatever you're doing
'cause that version is incredibly limited and has shitty code as far as I know

Can anyone tell me why the final "You are no longer in combat. You may leave the game now" message won't show up for 20 ticks after the countdown

[blazing ocean]

what are you trying to do

[near furnace]

an action text countdown, 15 seconds to 1, then it says "You are no longer in combat" in green text

i made it a method so i can use it in my combat thingy

[blazing ocean]

and why the weird fade thing?

[near furnace]

yeah

ill remvoe it

i thought it was going to act like a fade effect like in titles

but action bars are stiff, they dont have any fade effects

[blazing ocean]

They do?

You just can't change it

[near furnace]

yea, no need for fade effects

but can you help me with the problem

the final message wont show

[near furnace]

public void sendActionBarWithFade(Player player, String message) {

        int defSecondsLeft = 15;

        for (int secondsLeft = defSecondsLeft; secondsLeft >= 0; secondsLeft--) {
            int delay = (defSecondsLeft - secondsLeft) * 20;
            int finalSecondsLeft = secondsLeft;

            Bukkit.getScheduler().runTaskLater(plugin, () -> {
                if (finalSecondsLeft > 0) {
                    player.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent(ChatColor.RED + message + " (" + finalSecondsLeft + " seconds left)"));
                }
            }, delay);

            Bukkit.getScheduler().runTaskLater(plugin, () -> {
                player.spigot().sendMessage(ChatMessageType.ACTION_BAR, new TextComponent(ChatColor.GREEN + "You are no longer in combat. You may leave the game now"));
            },(defSecondsLeft + 1) * 20);
        }
    }```

Here is the code without the weird fade thingies

[blazing ocean]

just run a timer task lol

[near furnace]

timer task? those exist??

[blazing ocean]

task timers

[near furnace]

thank you so much

i thought for loops was the only way

❤️

[fading drift]

good idea i’m going to use timer task for myself

[inland hemlock]

I want to give players Enderman vision via packets.

                man.setAI(false);
                ClientboundSetCameraPacket cam = new ClientboundSetCameraPacket(((CraftEnderman)man).getHandle());

                ServerPlayer cp = ((CraftPlayer) p).getHandle();
                ServerGamePacketListenerImpl ps = cp.connection;

                ps.send(cam);
                man.remove();```
Problem is that this will teleport the player into the entity and even removing it makes the player unable to move afterwards.. It's liike being in Spectator mode without being in spectator mode. Only way to come around this is killing the player, afterwards he is able to move + has the vision.
Anyone know a possible workaround?

[fading drift]

possibly just packet log the packets that are sent when you exit endermen from spectator mode and send those

[inland hemlock]

Sounds promising, gonna try that ty.

[blazing ocean]

And why not just use the API?

[inland hemlock]

Didn't know spigot had it

[blazing ocean]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#setSpectatorTarget(org.bukkit.entity.Entity)

[inland hemlock]

Player has to be in spectator mode for this.

[blazing ocean]

Setting the camera in other gamemodes is extremely buggy and is rather UB

[quaint mantle]

hii

[pseudo hazel]

UB?

[inland hemlock]

Well I want that vision in any gamemode with free movement for the player.

[blazing ocean]

This is pretty much what can happen when you do this

[blazing ocean]

undefined behaviour

[pseudo hazel]

alr

[blazing ocean]

Not possible I believe, since the players camera needs to be set to an enderman which also locks the position

[inland hemlock]

If you kill the entity + the player it does work.

Problem is just that I want to avoid the "killing" the player.

[blazing ocean]

Well hard to kill em without killing em kek

[pseudo hazel]

that still sounds very buggy lol

[inland hemlock]

Yes thats why I am looking for an alternative way?

[pseudo hazel]

shader in a resourcepack

[blazing ocean]

Not without UB

none of that is supported

[blazing ocean]

Honestly just do this ^

You can copy the vanilla shader into your shaders and trigger it based on game time

[quaint mantle]

so i saw this deprecated, is there any method i can use instead?

[pseudo hazel]

go through the entries of a team

and match the player name

[quaint mantle]

oh alr ty

[pseudo hazel]

iirc player teams are just entries with the players getName()

[mortal hare]

i've just realised that hybrid of both spaces and tabs is the best imo

prove me wrong

for example i have such table:
Name\tType
Foooo\tCat
Bar\w\w\w\tDog

this would allow me to adjust spacing between columns but wouldnt alter leading padding of the Name column with Bar as a Name

[slender elbow]

that's such a stupid deprecation reason lol

[mortal hare]

i mean it doesnt really represent the intial purpose of the scoreboard system in minecraft's nms code

but yeah

[slender elbow]

just because teams can contain more than just players doesn't mean that method should be deprecated

why not let me get the team of a player? players are valid team members

[mortal hare]

i guess spigot is trying trying to thin out the line between Bukkit API and NMS lately

[eternal night]

"lately"

that deprecation has existed forever

[slender elbow]

yeah lol

[mortal hare]

ok

im wrong then

https://tenor.com/view/idk-shrug-tarryn-gif-22143231

[eternal night]

Now, the question is, if I open paper, will we have fixed that

Good job mm

[slender elbow]

getEntityTeam isn't deprecated, so I can pass an Entity, but i am not allowed to pass an OfflinePlayer? 🙃

sigh

[eternal night]

damn, yea that method is deprecated since 2015

[slender elbow]

nvm me i'm lookingat the wrong jd run

Hello, how can I do a synchronous bukkit task from an asynchronous task ?

[river oracle]

Use the scheduler runTask

[cinder abyss]

okay thanks

seems logical

[mellow edge]

Hello I wonder whether there is a way to place a sponge to not soak up water, like any property or something. I already tried:
-sending block change to the player that the sponge is there (even if it is not), but this works weirdly for example if I send another block change on top of the previous one
-setType(Material.SPONGE, false /*Physics*/)

but none work

I know I can cancel the absorb event but I wonder whether I can just somehow switch off this behaviour

the actual thing I am trying to do is to immidiately place the sponge down, but make it absorb water in stages (customly)

[river oracle]

You need to use the event

[thorn crypt]

Hey, I have this code using NBTApi to put a NBT on an item (made for blocks especially) and i can't pass a door (1.12.2) (Material.WOODEN_DOOR or any type of doors)

public void giveTierBlock(Player player, Material material, int amount, int tier) {
        ItemStack item = new ItemStack(material, amount);
        ItemMeta meta = item.getItemMeta();

        int life = getConfig().getInt("tier." + tier);
        List<String> lore = new ArrayList<>();
        lore.add(" ");
        lore.add("§8[§7Tier§8] §c" + tier);
        lore.add("§8[§7HP§8] §c" + life);
        lore.add(" ");
        meta.setLore(lore);
        item.setItemMeta(meta);

        NBTItem nbti = new NBTItem(item, true);
        nbti.setInteger("Tier", tier);
        nbti.setInteger("Life", life);

        player.getInventory().addItem(nbti.getItem());

[kind condor]

Hi can I make my plugin carries a datapack just like mod?

I want to make wither no able to break blocks, so I want to add all blocks to #minecraft:wither_immune

[young knoll]

Probably easier to just use a plugin for that

EntityExplodeEvent/EntityChangeBlockEvent iirc

[bold plume]

Do I have to stop using creaturespawnevent for my mob plugin because I need to spawn mobs on blocks like clay?

When is creaturespawnevent called? Is it called when the chunks are loaded (chunkloadevent) or is it simply a runnable that goes through all players and selects a coordinate for each nearby player and calls the creaturespawnevent for that player?

[near furnace]

can someone help me with my code? i made this countdown thingy for my combat log plugin, and im having trouble with the countdown. I want my countdown to restart everytime a player hits someone but it only registers the first hit.

[proper cobalt]

yo

can text displays have more than one color

like background color

or if i wanted more than one background color i would have to use more than one text display

all i see is this

[chrome beacon]

You'd need more than one text display

[bold plume]

int y = world.getHighestBlockYAt(x, z);

    Location randomLocation = new Location(world, x, y, z);
    player.teleport(randomLocation);

[bold plume]

Will this suffocate the player?

[vast ledge]

No...

[blazing ocean]

why would it....

[vast ledge]

Since, it's getting... The highest Block at that location?

[bold plume]

I don't need to add +1 to Y?

[vast ledge]

What would they suffocate in air?

[bold plume]

so the returned block is always air?

[vast ledge]

If you want them to be on top of the block yes

Last time I check my feet to suffocate

[bold plume]

wdym

[vast ledge]

The players feet will be inside said block

[bold plume]

getHighestBlockYAt corresponds to the coordinates of an AIR always?

[vast ledge]

Since ur getting the location of the block

[vast ledge]

It's going to return the highest Block, that most likely, don't quote me on this is transient

Isn't*

So a solid

[bold plume]

So the players feet will be inside the solid block?

[vast ledge]

Yes

Do + 1 if you want them above, but they won't suffocate either way

[bold plume]

I don't know why this isn't happening

[vast ledge]

What is happening?

[bold plume]

my feet are in AIR

and the block below the feet is a solid block

[vast ledge]

Without the + 1 or with?

[bold plume]

without the +1

idk why

[bold plume]

i'm using getHighestBlockYAt but is the same thing ig

[vast ledge]

That's what the API says

[bold plume]

Maybe Minecraft itself handles unsafely teleports

[bold plume]

everything is ok then

[bold plume]

You said it was a solid but it's an AIR

[vast ledge]

If you don't add + 1 it should be a solid

That's at least what the API says

[pseudo hazel]

if thats incorrect, it sounds like a bug

[vast ledge]

Try logging the location and look what's at that location

[proper cobalt]

yeah makes sense

btw do u know the method to make the text bigger

on a text display

cant find it

[chrome beacon]

The transformation has scale

[proper cobalt]

ah yeah

        final Transformation transformation = header.getTransformation();
        transformation.getScale().mul(10);
        header.setTransformation(transformation);

its not getting any bigger

[chrome beacon]

I would assume scale isn't mutable

so mul returns a modified copy

[proper cobalt]

theres no setter for setScale tho

[chrome beacon]

Make a new transformation

[proper cobalt]

yh

        final Transformation transformation = header.getTransformation();
        final Transformation transformation1 = new Transformation(transformation.getTranslation(), transformation.getLeftRotation(), transformation.getScale().mul(10), transformation.getRightRotation());
        header.setTransformation(transformation1);

idk doesnt do anything

[spiral light]

Is it possbile that if you cancel the InventoryClickEvent because of swapping a item in the inventory to the offend does not work 100% and displays a ghost item in the off hand ?

[bold plume]

switch is faster but uses more processing than if (condition || condition || ...) ?

[slender elbow]

they are two entirely different things

[proper cobalt]

I'm doing this
display.setAlignment(record.isLocal() ? TextDisplay.TextAlignment.LEFT : TextDisplay.TextAlignment.RIGHT);
And putting the text display at a location, but the location is still like the center of the text display

not the allignment

I'm guessing its cuz when I spawn it, this isnt taken into consideration

only after ofc

so what can i do?

[vagrant stratus]

Aight before I go copying NMS classes directly into my plugin, any idea on if spigot has something similar to the DifficultyDamageScaler class built into it already? It handles calculating difficulty stuff, used for things like if zombies should pick up loot & stuff like that
NMS class code: https://paste.md-5.net/olosehujoc.java

[proper cobalt]

can anyone help with this please

[outer river]

hello, a death a equivalent to a world changing (according he respawn in a different world) or i need to use the PlayerDeathEvent in addition of PlayerChangeWorldEvent ?

[bold plume]

In my mob generation plugin that is being made to replace vanilla mob generation, should I run entity#setRemoveWhenFarAway(false) and do my own task to despawn the mobs? If I leave it true, I can't control the mobs that were despawned because they were far from the players, or can I?

[proper cobalt]

guys is it possible to make text displays too long text only downwards instead of up and down??

[bold plume]

For me to control all the mobs that I spawn, can I store them with a List<LivingEntity> or do I have to have a list of all the ids?

[sonic goblet]

I would store them in a list of their UUIDs

[quaint mantle]

if i have a brigidier command how can i register it so it can show up in /help with the info

[river oracle]

Nms

And then make your own help command

[eternal night]

wat

[river oracle]

Bukkit draws from the command map

[quaint mantle]

awhh

can i add my comamnd to the command map

[river oracle]

Which I belive should include brig

[eternal night]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/help/HelpMap.html

grab the servers help map, smack an entry in there

[river oracle]

Top 10 things I didn't know existed

Wtf

Well there's your answer

[quaint mantle]

when i register a command through the plugin.yml it shows the description and the aliases and the usage

where would i put that in the helpmap

[river oracle]

Read the docs

The HelpMap is the correct solution

[quaint mantle]

what is a amendment

[river oracle]

Amendment means to add

[quaint mantle]

nvm i was looking at helptopic

[eternal night]

[river oracle]

You've been coding minecraft stuff longer than I've been using a computer

Hush

[eternal night]

👴 fair

[river oracle]

Let that set in old man

i forgot how to add nms for spigot

[young knoll]

?nms

[undone axle]

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

[undone axle]

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

[quaint mantle]

ok thakns

[sly topaz]

too bad the topic factory requires of a Command subclass

one could create a dummy Command that delegates to brig but eh

[sly topaz]

ig everyone just believed it was some obscure bukkit feature and would rather replace the help command with a custom one anyway

I did know it existed, but forgot of it for the longest time

update your Java version, and make sure Maven is using the same version as your project

also, don't use the target/source entries, you can use the release entry nowadays to replace these two

<groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>

  <configuration>

...

like this

[soft cairn]

this is my run config: https://i.postimg.cc/x1y3Tz1w/image.png

[bold plume]

Why am I seeing the name "ANIMAL"?

entity.setCustomName("ANIMAL");
entity.setCustomNameVisible(false);

[young knoll]

You’ll always see it when looking directly at them

[bold plume]

but I would like to set a name without being visible

[sly topaz]

you're using JDK 20

[young knoll]

You’d have to mount a passenger on the entity

However this sounds like

?xy

[undone axle]

https://xyproblem.info/

[sly topaz]

Ctrl + Alt + Shift + S, and where it says project version change it to jdk 21

[soft cairn]

there is no jdk 21 option here(just amazon corretto), there is openjdk 23, is that ok?

[river oracle]

Use Java 21

Not 23

You should download 21

[quaint mantle]

Java is not C#

[young knoll]

Why not

[blazing ocean]

Okay but is it Rust?

[river oracle]

keen observation

[quaint mantle]

Why bro deleted the messages 😭

[river oracle]

to make you look dumb

it totally worked btw!

[stuck oar]

            
            CustomFish caughtFish;
            do {

                if (caughtFish == null) return;
            } while (!canCatchFish(player, caughtFish));
            
            handleCatch(player, caughtFish);
            int xpReward = calculateXpReward(caughtFish.getRarity());
            plugin.getPlayerLevels().get(player).addXp(xpReward);
        }```

how can i cancel the vanilla drops from this?

if i use event.setCancelled it doesnt allow the player to reel in the rod

[quaint mantle]

e.getCaught().remove() ?

[stuck oar]

perfect thanks

[sly topaz]

why not 23

does Spigot also do ASM shenanigans which aren't forwards compatible?

[young knoll]

Yes

[sly topaz]

sadge

hope someone smart enough comes along to standarize stuff like that across the various server platforms so that it stops being necessary to explicitly support newer jdk versions

[young knoll]

You won’t see ASM leave spigot any time soon

It’s done for backwards compat

[sly topaz]

it isn't about it leaving, it is about figuring out a way to do it without it being a show stopper for newer java versions

[young knoll]

Ask the ASM library devs :p

[slender elbow]

i mean, they can't

classfile api 🙏

[river oracle]

they could if they hired me on

I mean I made inventory PR I can pretty much do anything

[slender elbow]

too bad they don't hire

[river oracle]

yep precisely the issue

meanwhile I'm on a downstream spigot forks payroll to stop the production of the greatest bukkit competitor ever conceived redacted

[eternal night]

I thought we wanted to keep that private

[river oracle]

My bad totally redacted that statement

I mean theoretically it could be a possibility

But definitely isn't

[eternal night]

Exactly certainly isn't

[river oracle]

Uh oh I just got a visit from John NDA

He's holding a photo of my message

Oh god

[eternal night]

Good, next time itll be john lawenforcement

[eternal oxide]

or john concrete shoes

[young knoll]

Speaking of John

[eternal night]

john horse head comes around first

[young knoll]

What happened to John paper

Aka aikar

[eternal night]

enjoying steaks

I presume

[young knoll]

Fair

I thought maybe he ate so many he turned into one

[eternal oxide]

He'd start mooing before that happens.

[tawny remnant]

arrow.setVelocity() acting weird? It shows the arrow going not straight from the player.getLocation().getDirection() but even if a block is not in it's visible trajectory it hits the block. What causes this issue and is it fixable?
Edit: The arrow does travel straight but not it's animation or something like that

[young knoll]

Don’t set it so high

The client doesn’t like it

[tawny remnant]

its travelling from the player's eye level

[eternal oxide]

velocity.length not the height of teh arrow

[tawny remnant]

oh

[bold plume]

Is it more expensive to spawn 100 entities in a location even if there are no players nearby or should I check if there are players in that location to spawn the entities?

[tawny remnant]

wouldnt the entities despawn if there werent players nearby?

[bold plume]

I already do this but I have a spawn mechanism

[bold plume]

And I would like to know the best way to spawn the mobs

[tawny remnant]

define "best". what do you mean by that

[eternal oxide]

only spawn when there is a reason to spawn. No players = no reason to spawn

[bold plume]

I have to go through all the players close to a location since most of the time there are players nearby

and checking whether there are players close to this area is checked quite frequently

[young knoll]

Check if the area is loaded first

Then you can do some distanceSquared checks if you want

[eternal oxide]

and you don;t need precise checks. Just check chuhnk coords of player to the cunk you want to spawn in. +/- X

[young knoll]

That works too

[bold plume]

Checking if the chunk that the mob will spawn in is loaded is less costly than going through all the players? It's just that a world has more chunks than players

[eternal oxide]

much less costly

[bold plume]

can you tell me why

because there are more chunks than players

[eternal oxide]

if its not loaded it means there is no player anywhere near

um

you are doing a spwn system?

[bold plume]

But isn't going through all the chunks more expensive than going through all the players? There are more chunks to go through than there are players online

yes

[young knoll]

You don’t go through all chunks to check if it’s loaded

[eternal oxide]

in all chunks?

[bold plume]

How not?

[eternal oxide]

ie your spawns can happen in any chunk?

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#getLoadedChunks()

[bold plume]

There are more chunks loaded than players too

[bold plume]

Yes, that part is already done. Now I'm making a separate system that has more mobs in a specific area

[bold plume]

All chunks loaded*

[desert aspen]

Hi guys, im trying to make that all the living entities that spawn have a chance to be a life stealer, and when it hits a player it takes away from them 1 heart, and once a timer runs up they give it back, also i wanna make that the mob are invisible until they attack a player, the error is that:
1 The mob takes away the heart but he won't gave it back
2 The mob spawn as invis but when it attacks a player it stays the same
https://paste.md-5.net/icehubahuf.java
That's the code

if anyone could tell me whats the error pls

[young knoll]

World#isChunkLoaded

[slender elbow]

alternatively you could pick a random chunk around a player

if that chunk is in your "special area" then, run that special logic

[young knoll]

My special area? 😳

[bold plume]

but this method loops through all loaded chunks. Through all players is less expensive

[young knoll]

Are you sure it does that

[bold plume]

I suppose so

[young knoll]

I’m going to guess Mojang has some sort of coordinate mapping for chunk lookup

[bold plume]

public boolean isChunkLoaded(int i, int j) {
return this.chunks.containsKey(LongHash.toLong(i, j));
}

Does this hashmap not contain all loaded chunks?

[young knoll]

Yes but hashmap lookups don’t work that way

Yay hashmaps

[slender elbow]

the "hash" in "hash map" is very important

[bold plume]

how they work

Ok, I saw it here and I already got it

boolean isChunkLoaded(int var1, int var2); Are the ints the x and z of the coordinates?

[slender elbow]

chunk coordinates

[bold plume]

How do I get these values ​​through x and z coordinates world?

[young knoll]

x >> 4 and z >> 4

[slender elbow]

there's also a isChunkLoaded(Location) in case you didn't see it

[bold plume]

and is it possible to get a randomly loaded chunk with cost O(1)?

[slender elbow]

sure, generate a random number between 0 and size of array returned by getLoadedChunks, then get the Chunk at that index

[bold plume]

Ok thank you

[young knoll]

Yay efficiency

If only the average developer had more time to care about that these days

[bold plume]

That's why it's average xd

This is the most efficient way, right?

public static Location getRandomLocationInChunk(Chunk chunk) {

    World world = chunk.getWorld();

    int x = chunk.getX() << 4 + random.nextInt(16);
    int z = chunk.getZ() << 4 + random.nextInt(16);

    int y = world.getHighestBlockYAt(x, z);

    return new Location(world, x, y, z);
}

[slender elbow]

looks good

[worldly ingot]

Bonus points for using << because it looks cool 😎

[slender elbow]

actually true and accurate usage of chunk & block coordinates

unbelievably based gigachad

[bold plume]

ok thanks

For some reason this chunk (and there are many) are loaded LOL: mobSpawn: Location{world=CraftWorld{name=world},x=-2240.0,y=69.0,z=-6815744.0,pitch=0.0,yaw=0.0}; type: COW

and the world only has players from -1000 to 1000

[chrome beacon]

You probably loaded it

Certain APi calls will do that for you

[slender elbow]

hold up

you wanna do (chunk.getX/Z() << 4) + random.nextInt(16)

those parentheses are very important lmao

@bold plume

those coordinates looked very strange

[bold plume]

let me see

[slender elbow]

otherwise, + takes precedence over <<, so you end up doing chunk.getX/Z() << (4 + random.nextInt(16))

which is gonna be a lot

[bold plume]

make sense

Now it's working perfectly. Thanks

[eternal night]

[slender elbow]

i was more so pointing out the fact they were using it

ahem

many people just do * 16 and call it a day lol

negative chunks:

[eternal night]

[bold plume]

What's wrong with doing * 16 in negative chunks?

[remote swallow]

you go up not down

[bold plume]

Does the compiler not replace * 16 with << 4 for example?

[slender elbow]

the compiler doesn't really do many optimisations besides constant folding

hotspot does all the cool stuff

[violet blade]

was the infestation potion effect added to the api?

[slender elbow]

iirc the issue isn't with going from chunk to block coords, but from block to chunk coords

except for the edge case where the bits overlap the sign bit but the game will shit the bed before that ever happens

[eternal night]

Yea, your issue basically is that int division -10 / 16 isn't the same as -10 >> 4

[stuck oar]

how do i get methods from a different plugin, ive got the depend: [] in there and the bukkit.getPlugin whatever but im not actually sure on how to get the methods

[bold plume]

But in this case the problem would not be with * 16 but with / 16

[slender elbow]

yeah but it doesn't hurt to be consistent

[chrome beacon]

Add the other plugin to that depends and then import it to your project

After that you should be able to use the other plugins classes

[stuck oar]

I’ve tried it just says something about the spigot repo

[chrome beacon]

Sounds like you didn't put a valid dependency and repo

Send the pom

?paste

[undone axle]

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

[stuck oar]

I didn’t put a repo idk what to put

[river oracle]

Twos compliment goes so crazy

Fucks me up hardcore

[chrome beacon]

Depends on the dependency

[river oracle]

When I'm working with bytes in Java I sometimes forget they're signed

[eternal oxide]

yeah that throws me off at times

[stuck oar]

I’ll send it in a second

[worldly ingot]

Yes

PotionEffectType.INFESTED

[violet blade]

yeah for some reason my gradle wasnt importing it correctly but after restarting the IDE i got it to work ty

[graceful oak]

Idk if im not remembering correctly but I swear I have used mining fatigue at a value of -1 before and it makes it so the player cannot break blocks without a slowdown of swing speed but I cant seem to replicate this in minecraft 1.21.1 am I just crazy or did this used to be a thing?

[rough ibex]

Maybe it wrapped around to 255?

and high effects tend to mess it up

[mortal hare]

there's nothing more worse

than seeing variable naming convention like this

[rough ibex]

they call HEIGHT(c) a lot

[nova notch]

what the fuck

[mortal hare]

that's linux x11 dwm code for you

this code is older than me

its somewhere around 23 yrs old

[blazing ocean]

I knew it

I believe I'm actually changing that code

[grand flint]

If I want to send a player to a limbo when they afk in the backend server should I use the plugin messaging channel?

[slender elbow]

you can do that, yeah

[grand flint]

Is there a better way?

Also do I need a plugin on the proxy for that?

[sly topaz]

I'd just use something like NanoLimbo

can't beat a server specifically built for that

[grand flint]

Yeah that's fine?

How should I send the player to nanolimbo

Also isn't this a bungee error

[fading drift]

I used to get that with run-paper

but I never could fix it

[fading drift]

anyone happen to have a system for player nametag prefixes using teams for 1.8

[spice cove]

is there a way to simulate a player you can control or something

like to test a plugin

or do u need another acc

[sly topaz]

if you don't have another account, just turn online mode off and you can use one of those bot clients to join the server aside from your usual account

either that, or spawn a NPC, but it won't do anything unless you send the packets to make it do things, which is way too much work for testing a plugin

my usual recommendation instead is to just use a different entity other than a player, since that's easier to spawn and control

[spice cove]

does wurst work lol with like the cracked account thing

cuz like i need it to send a command

im trying a plugin and seeing if that works tho first

[sly topaz]

you can make any entity send a command

[spice cove]

can you see like the messages they get

i wanna have like a prompt that says click here and like it runs a command

[sly topaz]

you can probably use /execute as ... for that, yeah

still, why are you not able to test this by yourself

[fading drift]

is there a way to hide a block from a player but show for everyone else

like maybe send the player a packet that the block changed to air

[sly topaz]

Player#sendBlockChange to air

that'll only "hide" the block for the player in question

though since it only sends the block change, you have to be careful of physics updates and whatnot reverting the change

[fading drift]

thank you

how can I change my logger to warn only

[sly topaz]

you mean, to only display warn records, or to make all records warn level

for either choice, you can use a Filter

[fading drift]

first

[sly topaz]

public YourPlugin() {
  super();
  getLogger().setFilter(this::displayingOnly);
}

private boolean displayingOnly(LogRecord record) {
    // or another type of filter...
    return record.getLevel().equals(Level.WARNING);
}

[buoyant viper]

damn, not even running that on onEnable?

just going full force in the constructor?

absolutely wild, buckaroo

[sly topaz]

eh, the place doesn't really matter, the constructor is going to be the earliest so I used that but onLoad/onEnable are just as valid

doing it on the constructor makes the "loading YourPlugin" log dissapear lol

public class VillagerGossips extends JavaPlugin {

    public VillagerGossips() {
        super();
        getLogger().setFilter(this::displayingOnly);
    }

    private boolean displayingOnly(LogRecord record) {
        // or another type of filter...
        return record.getLevel().equals(Level.WARNING);
    }
    @Override
    public void onEnable() {
       getLogger().info("testing if it warns");
       getLogger().warning("should actually warn");
       getLogger().log(Level.SEVERE, "testing");
    }
}

https://pastes.dev/obCiv4YbU1

never realized how sneaky one can be by doing something like this

loading/enabling record should actually be sent from the parent loggger and not the plugin's to avoid this tbh

wonder if behavior is the same on Paper considering they use a completely different logging backend

[proper radish]

how would i go about copying world using another world folder ?

like without using worldCreator ? do i need to use NMS ?

[chrome beacon]

hm? Could you not just copy the folder?

Or do you just want another world with the same seed

[proper radish]

my template worlds path ./plugins/MyPlugin/template-maps/.
lets say i wanna start a game, so i need to create/generate a new world from the template maps folder (making a new copy)
so i would copy the entire world folder from the template-maps folder into the WorldsContainer (which is .)
then i would rename that folder's name (world name) . and everything is good at this point ..
BUT the issue is i can't just load/get this new world using its folder. i need to use WorldCreator then worldCreator.createWorld()
and this method will make a new world folder with the same name only

irdk what i supposed to do, i just wanna make a new copy of the world thats it.

[chrome beacon]

Create the world using the world creator

It will read your folder as long as it has the same name

[proper radish]

this is gonna duplicate the world folder ?

[chrome beacon]

It won't

It will join load the world

[proper radish]

[chrome beacon]

is that your plugin?

[stuck oar]

MainFishingAlgorithm is the plugin i want to use methods from

[chrome beacon]

That didn't answer the question

[stuck oar]

What was the question sorry

[chrome beacon]

.

[stuck oar]

It’s in the pom.xml of my plugin yeah

[chrome beacon]

I was talking about MainFishingAlgorithm

[stuck oar]

MainFishingAlgoritm is the plugin that i want to get the methods from, MainCustomRods is the plugin that uses those methods

[chrome beacon]

yeah I understand that

[stuck oar]

So how do i access the methods

[chrome beacon]

Start by answering the question

is MainFishingAlgorithm your plugin

[stuck oar]

I’m so confused what do you mean? Is it the plugin im getting the methods from or is it the plugin that im using the methods in

[smoky anchor]

I think he's asking if you created that plugin

[chrome beacon]

I am

I want to know if you made the MainFishingAlgorithm plugin that you're trying to depend on

[stuck oar]

Yes i did

I have the source and everything

[chrome beacon]

So you don't have a repo for it

[stuck oar]

No

[chrome beacon]

Run mvn install in that project to use your local one

Alright thanks

yo does anyone know why morepersistantdatatypes stopped working?

> Could not resolve all files for configuration ':compileClasspath'.
   > Could not find MorePersistentDataTypes-2.4.0.jar (com.jeff_media:MorePersistentDataTypes:2.4.0).
     Searched in the following locations:
         https://hub.jeff-media.com/nexus/repository/jeff-media-public/com/jeff_media/MorePersistentDataTypes/2.4.0/MorePersistentDataTypes-2.4.0.jar

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

It worked fine a few weeks ago, now I load the project without changing anything it doesn't work anymore. I compared it to the example on github and its the same

    implementation 'com.jeff_media:MorePersistentDataTypes:2.4.0'
}```
```repositories {
    mavenCentral()

It seems my other projects using morepersistantdatatypes get the same error

[buoyant viper]

@tender shard whatd u break

[proud badge]

does it not work for you either?

[buoyant viper]

idk, just figured id ping him for u

[proud badge]

can anyone with a project depending on morepersistantdatatypes try to compile it pls and tell me if it works

[buoyant viper]

wait how did gradle search alexs repo without it being in ur config

[chrome beacon]

Looks like the repository got removed

[proud badge]

bru

[chrome beacon]

2.4.0 is available on maven central

so just use that

[proud badge]

yeah thats what im doing

2.4.0 from maven central

and it aint working

[chrome beacon]

Error says it's searching mfnalexs site

and not central

You might have a cached failure, force an update

bukkit? I hardly know her!

[misty ingot]

hey, is there a way to tab complete after a custom character instead of only in commands?

[chrome beacon]

You send fake player information with what you want to autocomplete as their username

[misty ingot]

how would i go about doing this tho?
example use case:

@(tab complete all online player names here)

[chrome beacon]

send one fake player info for each thing you want to auto complete
