[smoky oak]

is it included now or something?

[eternal oxide]

yeah, you don;t need to specify javadoc dependencies

[tender shard]

if you want to keep the javadoc thing for whatever reason, then use spigot-api

spigot doesnt have javadocs

[eternal oxide]

javadocs are API only

[smoky oak]

ah

i just thought it screwed up the same way it did with the api

[tender shard]

it's not needed to add the javadocs, just do "Download sources" in IJ

but still, what do you even need CraftBukkit classes for?

[smoky oak]

i just wanted to know if it'd be available if i needed it

i once again forgor to register the event listener

cuz I'm insisting on separating them out

[upper hazel]

how to allow breaking only certain blocks

[tender shard]

no clue what that is

is that a command executor? a listener? your onEnable() ?

[upper hazel]

createRegion

metod

worldguard api

[orchid trout]

cancel block break event when you dont want the block being broken?

cant you check what region it is with worldguard

[upper hazel]

I create a region and I want blocks to not break in this region, but not all

to break those blocks that are in the List

allow

to break

[tender shard]

then listen to BlockBreakEvent, check if the block is inside your region (I'd create a separate worldguard flag for that, instead of hardcoding one region), and then if it's inside your region, check your list?

[upper hazel]

Is it possible to change flag parameters?

flag parameters cannot be changed?

[tender shard]

StringFlags

[upper hazel]

a

[half bane]

what should I use instead of PlayerEditBookEvent.getSlot()? getSlot() is deprecated but I really need to get the ItemStack or the slot

[abstract spindle]

If I want to register a FurnaceRecipe I have the option between RecipeChoice.ExactChoice and RecipeChoice.MaterialChoice is there a way to register it where it only checks the Type and the CustomModelData ?

[tender shard]

method looks fine to me, idk why it's deprecated

it says it's because it might have been from offhand but offhand hsould return -1

it's deprecated since 1.13.1, so very unlikely that it gets removed now

it was deprecated in the same commit that actually added offhand support lol

I'll open a jira issue

[tender shard]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/pull-requests/897/overview if it gets merged, it won't be deprecated anymore

[smoky oak]

can someone explain why setting the cooldown of a material doesnt prevent me from using it -.-
I'm setting the shield cooldown but the player keeps the shield raised, and theres no method in the api to lower a player's shield far as i can tell

searching for shield is 0 results

[dire marsh]

Client-side issue, paper has clearactiveitem which can fix that I believe

[smoky oak]

it needs to work in spigot

[dire marsh]

ok

have fun then

[smoky oak]

hm

is there a stash of paper's patched server file anywhere?

I'm trying to look at the method

[dire marsh]

use plib and send the metadata packet with the active item field

https://wiki.vg/Entity_metadata#Living_Entity

or you can do reflection/nms, calling the method this calls: https://github.com/PaperMC/Paper/blob/master/patches/server/0494-Add-LivingEntity-clearActiveItem.patch

[spare hazel]

 if(blockManager.getBlock(block.getType()) >= account.getLevel()){
            account.setXp(account.getXp() + blockManager.getBlock(block.getType()));
            new RegeneratingBlock(block.getType(), block.getLocation()).runTaskLater(SkyMineCore.getInstance(), 400L);
            if(account.calculateRankup()){
                player.sendTitle(SkyMineCore.getInstance().getTextManager().getText("account.levelup"), null, 30, 200, 70);
                Bukkit.dispatchCommand(Bukkit.getConsoleSender(), "eco give " + player.getName() + " 50000");
            }
        }else{
            e.setCancelled(true);
            player.sendMessage(SkyMineCore.getInstance().getTextManager().getText("block.error.lowlevel"));
            return;
        }```

why cant the player Mine Stone Which Needs Level 1 When He Is Level 2?

oh wait

im so dumb

i know

i should create a RegeneratingBlockManager Class

and asign each block a offTime or something

each 10s i remove 1 offtime from all of them

[upper hazel]

can i make an exception for certain blocks? How

i try create regions

but need allow break blocks in this list

[smoky oak]

does that require nms or just spigot without -api?

iirc handle was part of spigot wasnt it?

yea i aint figuring this out

[grizzled oasis]

How can i load itemstack as items to display into an achievement https://paste.md-5.net/uxazayuriw.bash (currently only supports items only name)

[solar jungle]

HI!! I'm seeking assistance to implement a feature on my Minecraft server. What I aim to achieve is sending a warning message to players attempting to join the server with versions earlier than 1.16.5.

[cobalt thorn]

You can use viaversion there’s something inside configuration

There are examples there

[solar jungle]

But I want to create my own plugin for this.

[cobalt thorn]

You are using viaversion?

[solar jungle]

No

[cobalt thorn]

What are you using

[solar jungle]

I'm just using my plugin, and that's it

[cobalt thorn]

Player cannot join in older version or newer

Only in the spigot version

[solar jungle]

Yes, but now I'm going to add ViaVersion. However, I want to get the code first, and then I'll add the ViaVersion plugin.

[cobalt thorn]

https://www.spigotmc.org/threads/how-to-get-version-of-player.463519/ use the event PlayerJoinEvent

[remote swallow]

via version is open source

[young knoll]

It also has an api to check the players version

[cobalt thorn]

And so what i gave the answer below with viaversion

[solar jungle]

That's what I want.

[cobalt thorn]

Inside the thread there’s the answer on how

[solar jungle]

So, ViaVersion is needed, right?

[cobalt thorn]

Pretty much yes

Via.getAPI().getPlayerVersion(player)

This is how you get it call it when the player is login

[solar jungle]

ViaVersion shows up in red for me.

[cobalt thorn]

Check console for errors

[spare hazel]

@EventHandler
    public void onBlockDropItem(BlockDropItemEvent e){
        if(e.isCancelled()) return;
        
        if(e.getItems().get(0).getItemStack().getType() == Material.ANCIENT_DEBRIS){
            e.getItems().get(0).getItemStack().setType(Material.NETHERITE_INGOT);
        }
    }``` guys will this work? _no i wont try it and see bcz i only have 4GB ram and i cant have 4 things open at the same time_

[undone axle]

https://tryitands.ee/

[spare hazel]

😐

[solar jungle]

I mean in the code, Via shows up highlighted in red.

Via.getAPI().getPlayerVersion(player)

[cobalt thorn]

You need to import the lib

[solar jungle]

How do I import the lib?

[cobalt thorn]

https://github.com/ViaVersion/ViaVersion you can find it here

[gilded granite]

how i can add fake players in tab with nms?

[solar jungle]

No problem, I'm new to this and I don't know where to find it. How about you guide me a bit on where to find it?

[cobalt thorn]

What are you using? (maven, gradle)

[solar jungle]

And how can I check that?

[cobalt thorn]

Do you have in your project a pom.xml?

And plus

[solar jungle]

Yes

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

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

[sterile token]

Which one returns the value if it already exists the key, or in case it doesnt exists create it, to then return the value?? Im dougthing btween computeIfAbsent() or putIfAbsent()

[cobalt thorn]

I recommend you to learn about java and maven too so you don’t have problems

[sterile token]

Totally agree, coding plugins without knowing Java its worst thing you can do

oh right, really thanks morice

Dont lost your time bro, some times people dont really wan tto learn

[cobalt thorn]

Just trying to help as much as possible

[sterile token]

oh perfect, its exactly what i expected. But i was getting an NPE, will see it. Maybe the NPE is caused inside the cooldown itself

Soryr for tagging also, and again thanks

[cobalt thorn]

If you don’t have the knowledge viaversion has already a system

[solar jungle]

Yes, but can I create my own as well?

[sterile token]

You are giving to many rounds, if someone dont know Java and want to code, best way is to tell just to learn java. Because if not its a mess helping them, because people here doesnt explain things in a none technical context so you wont understand nothing

[solar jungle]

And yes, I am using Maven

[sterile token]

But also why trying to create your own via version? There is no need to reinveint the wheel when it was alreadt invented

[cobalt thorn]

Not is own but just checking if they are under a version that already viaversion has integrated (https://viaversion.atlassian.net/wiki/spaces/VIAVERSION/pages/54100070/Configuration) as explained here, block-versions : “<1.16.5”

[sterile token]

oh right, i think i have something for that 1m

I will check into the tab api i have, which get the version from the client

[cobalt thorn]

I mean if the plugin has already that feature why code it

I sent even an example

[sterile token]

he?

[cobalt thorn]

?

[sterile token]

You cant get user version without libraries? Such as protocol lib or via version

[cobalt thorn]

I mean he wants to block users under a version using viaversion inside configs of it there’s blocked-version and you can do “<1.16.5” and all under it are blocked

[sterile token]

oh

but that isnt for #help-development, must be #help-server

[cobalt thorn]

He wanted to develop it but its for me not needed you can already do that and he hasn’t the knowledge so i recommend that

[grizzled oasis]

anyone?

[tender shard]

it always uses the lowest priority goal that returns true for canUse()

[sterile token]

You can use Random class*

what? I didnt catch what you mean with that

[tender shard]

you could just one wrapper goal that then randomly runs one, sometimes th eother goal

[sterile token]

When using scoreboards or tablist, is it better to handle them via threads or instead use bukkit tasks?

[gilded granite]

how do i add fake players to the scorebord?

[sterile token]

You mean to fake them in the counter?

[gilded granite]

in the tab yes

[sterile token]

scoreboard != tablist, different things

Scoreboard is the one on the right of screen

Yeah, best option is to use ProtocolLib because messing without its a disaster and you will lost much time

[lilac dagger]

to be honest, i find it much easier without it

[tender shard]

Same

ProtocolLib is much more complicated and messy than the NMS packet constructors

[sturdy heron]

Best option is packetevents

[slender elbow]

eh

[near mason]

naah

ProtocolLib is hard

without wrappers

and i think wrapper is outdated

[gilded granite]

I use nms for packets

but idk which packet is it

?

Im using mojang mappings breh

[slender elbow]

I mean, if you're using nms just see how vanilla/craftbukkit does it?

[lost matrix]

1. ClientboundPlayerInfoUpdatePacket with Action.ADD_PLAYER
2. ClientboundPlayerInfoUpdatePacket with Action.UPDATE_DISPLAY_NAME

For hiding simply send a ClientboundPlayerInfoRemovePacket

[half bane]

[lost matrix]

My guy, this project looks absolutely bombed

[bleak nacelle]

its actually working

i just cant import it to eclipse

[tender shard]

Ah yes, eclipse and maven

Always fun

[bleak nacelle]

https://ufile.io/y1i12xpu

this is the working plugin

[lost matrix]

Delete your target folder completely and try again

Und run mvn clean as well before compiling

Btw how do you compile?

[eternal oxide]

um, thats not a maven project imported

looks more like you decompiled a jar

[lost matrix]

*building artifacts incoming

[bleak nacelle]

@remote swallow made this plugin for me and im trying to fix bugs since he wont help anymore

[scenic onyx]

whot is?

[lost matrix]

Did you... import a zip file?

[bleak nacelle]

yes

[tender shard]

Lol

Have you tried extracting it indtead

[lost matrix]

How about you extract this zip and open the resulting folder as project.
No wonder the compiler cant create a folder inside your zip file project...

[bleak nacelle]

eclipse has option for importing zip file i used it

ill try manually copying the folder

[lost matrix]

You also have meta-inf files. Are you sure that this is a project and not decompiled garbage?

[tender shard]

Blame epic

[bleak nacelle]

i decompiled the .jar i need to edit the code to add functionality

[tender shard]

Didnt epic send you the source or a github repo link

[bleak nacelle]

he sent the jar

[tender shard]

@remote swallow send source

[bleak nacelle]

i dont think its needed since i can already decompile it

[tender shard]

And then?

You create the pom yourself?

[bleak nacelle]

no its in meta inf folder

[tender shard]

Well ok

[lost matrix]

Have fun recompiling this into a jar.
Editing an already compiled jar file is a really bad idea and will lead to problems.

[bleak nacelle]

why i can already see full source code not obfuscated

[eternal oxide]

decompiling is always a last resort

[lost matrix]

Thats not really the source code. This is what your decompiler thinks the source code could have looked like.

[tender shard]

decompiled code is like if you get a cake and try to turn it back into flour, sugar and eggs

the compiler is the blender and oven

[quiet ice]

Can affirm

[sterile token]

Totally agree, worst ide i have seen ☝️

[lost matrix]

eclipse, old man ide confirmed

[quiet ice]

IJ is the worst, yes.

[eternal oxide]

I like old 🙂

[quiet ice]

Cannot even have more than one project open in a single window

What is this? An IDE from 1995?

[lost matrix]

Ive also started with eclipse. Its fine.

[sterile token]

i mean is not issue if people like to broke their header using a nasty, outded and 2.000s IDE

[bleak nacelle]

im switching to codeblocks

maybe it will work

[lost matrix]

Look what you did Verano...

[bleak nacelle]

oh it doesnt support java

[quiet ice]

We had another person that was adamant about using VI for java ... although A) it was a troll and B) it was ages ago

[sterile token]

i mean eclipse for starting is well not that bad, fbut for huge projects forget about it. It takes ages to compile Maven, its a mess to install maven with it, etc

[lost matrix]

Why?

[eternal oxide]

Its better for large projects. Smaller memory footprint

[quiet ice]

Eclipse's only weakness is kotlin gradle

I feel like you used Eclipse for Java EE

[eternal oxide]

Yeah I can;t comment on Kotlin/Gradle, I don;t use them

[lost matrix]

Or kotlin alone. Or gradle alone.

[quiet ice]

That one does not come with Maven attached.

[bleak nacelle]

can i code in kotlin with eclipse?

[sterile token]

Imagine installing an IDE and having to install compiling tools apart, doesnt make sense haha

[eternal oxide]

For java you don;t have to install anythgin in Eclipse

[lost matrix]

Looks like someone didnt write any low level code before.
This is actually the norm.

[quiet ice]

Eclipse has great support of Groovy gradle - if you never touch any groovy files that is

[lost matrix]

XD

[quiet ice]

Technically yes but I wouldn't dare

[tender shard]

on mac you can

but on windows you indeed cannot

[quiet ice]

wut. what is that of an arbitrary limitation

[lost matrix]

That was the biggest obstacle that held me back from switching from eclipse to IJ.
And then i started using build tools...

[eternal oxide]

This would be a nightmare forIJ

[bleak nacelle]

i need name changer plugin which changes tab list name and name above head also in chat name can pay 20$ it already has some things done https://ufile.io/y1i12xpu

[sterile token]

Also why ppl till using build tools? When there are public repos which they already have artifacts up. And in remote!!

[tender shard]

IJ mac supports different projects in one window but they're split up into tabs

[lost matrix]

I know someone that might be able to write this
@remote swallow

[tender shard]

idk why would you need BungeeTest and FakePlayer and GroupManager open in the same window though

[eternal oxide]

because BT is the ONLY legal method of getting Spigot

[tender shard]

because we don't trust arbitrary illegal sources

[eternal oxide]

too lazy to have multiple workspaces or IDEs open

[bleak nacelle]

sure

[sterile token]

Dont you trust on io.codemc repo? Isnt the one from paper

[eternal oxide]

I also often work across multiple projects, if a bug is found It's there already and simple to open.fix

[tender shard]

no I don't, I only trust repos that host things legally

[lost matrix]

Im certain that paper has no public repos with an edited minecraft version on it.

[eternal night]

[lost matrix]

right?

[smoky oak]

I'm trying to get around that shield glitch where its apparantly not possible to manually disable it. I've been told to use https://wiki.vg/Entity_metadata#Living_Entity this packet, but can't seem to find much information on doing the protocol manually or protocollib.
Same person mentioned that https://github.com/PaperMC/Paper/blob/master/patches/server/0494-Add-LivingEntity-clearActiveItem.patch its fixed like this in paper, so I tried looking at the paper code, but if i throw the paper.jar into a decompiler it just spits out a list of patches.
Any ideas? I've been stuck for a while now

[willow yacht]

What is the best way to pathfind for an arrow to reach a player?

[shell robin]

Can anyone help with WorldGuardAPI knowledge? How do I check if the area where the player is walking is included in the region?

[eternal night]

indeed we don't redistribute jars containing copyrighted mojang work

codemc is a giant repo a shit load of people that did not make it into maven central can host their stuff in

[tender shard]

But literally everyone can upload to central

[icy beacon]

it takes brains

[quiet ice]

I should start uploading my plugins to central one of these days

[eternal night]

Yea, but that means you gotta upload content not breaking copyright protections

[tender shard]

Ah thats what you mean lol

[lost matrix]

Do you want to create aim assisted arrows or arrows that can go arround corners and hit a player in the buttocks.

[eternal night]

they also come with a public jenkins instance

so like

[willow yacht]

Create aim assisted arrows

[quiet ice]

The most difficult part is getting code signing to work otherwise it is dead easy

[eternal night]

so like, jitpack

[sterile token]

why microsoft would care if people publish their compiled sources. Why didnt they oblise all the devs containing to delete it from their OS? I always asked that to myself

Why they appeared public first of all, if they were protected by right licenses

[lost matrix]

https://worldguard.enginehub.org/en/latest/developer/
This should have enogh information to solve your question

[tender shard]

Isnt that only adding an execution for the sign-jar plugin and thats it?

[icy beacon]

oh speaking of that, I've always been able to sign my API properly but recently my gpg just broke and I've spent like a week trying to fix it lol. in vain

[eternal night]

not enforcing a copyright is a dangerous idea

[quiet ice]

Yeah but you also need to gen the keys and all that

[tender shard]

Yea sure

[eternal night]

smh, generating keys lol

a difficult operation

[quiet ice]

But it is still straightforward (at least under maven, didn't yet do it under gradle) - yes.

[tender shard]

Actually… someone who cant create a gpg key probably isnt able to write any useful dependency anyway lol

[sterile token]

What do you mean by that? Im interested in the topic now, i wanna learn more about it

[lost matrix]

Step one: Create a very precise impact prediction.
You need to know how faw away the arrow is about to land from your target
before your can correct the trajectory.

[quiet ice]

And if you don't have gpg.skip set to true in the pom it can get difficult for others to work with your project

[shell robin]

Oh, please don't do this to me. I have studied them many times and I do not know which one to base and how to use it. I would appreciate it if you could guide me as if to say, first do this, then this, and finally this. (Don't worry, I don't wanna spoonfeed.)

[tender shard]

If you knowingly allow people to do illegal things you‘re basically doing illegal things yourself

[quiet ice]

So if you want to do stuff properly it isn't completely straightforward

[lost matrix]

Do you just want to know which regions a player is currently in?

[sterile token]

Yes i know that if you break a license you are doing illegal things. But why the server jars were filtered / leaked, if they were protected by copy rights?

[eternal night]

what do you mean why

[tender shard]

https://github.com/JEFF-Media-GbR/JeffLib/blob/b2cea2f681d7ba382e03fb5fc27108d696e3a80e/core/src/main/java/com/jeff_media/jefflib/pluginhooks/worldguard/WorldGuardUtils.java#L67 check this and WorldGuardHandler

[sterile token]

to the fact that server jars where filtered. The reason itself

[eternal night]

filtered ?

[sterile token]

or leaked /published same thing

[eternal night]

I mean, they are leaked because mojang has to ?

how are you going to run a server

they permit you the right to have a copy of their work

[shell robin]

this guy is all over the spigot..

[eternal night]

you just aren't allowed to redistribute

[sterile token]

Why you cant if you made of fork, in theory with including their license you shouldnt have problems? So why spigot did i cant find a really clarify explanation

[shell robin]

Yes but I think it's been answered 😅

[eternal night]

there is no OSS licence, the minecraft server internals are not open source

[lost matrix]

Player player = ...;
// Get global region container
RegionContainer container = WorldGuard.getInstance().getPlatform().getRegionContainer();
// Get all regions which are applicable on a specific location
Location loc = player.getLocation();
RegionQuery query = container.createQuery();
ApplicableRegionSet set = query.getApplicableRegions(loc);

Too late. Here comes the spoon 🥄

[eternal night]

they explicitly do not allow redistribution

[sterile token]

right, but wont you be able to redistribute something they made it public. Its like a clown idea i mean, doesnt make sense tho

[tender shard]

Their license says „no“

[eternal night]

but it isn't public and allowed for redistribution

[lost matrix]

[smoky oak]

PacketContainer resetPacket = new PacketContainer(PacketType.Play.Server.ENTITY_METADATA);
resetPacket.getIntegers().write(8,0);```
`Caused by: com.comphenix.protocol.reflect.FieldAccessException: Field index 8 is out of bounds for length 1`
welp I'm out of ideas

[icy beacon]

because if stuff is yours and you allow others to use it you can set restrictions on how it can be used

[eternal night]

they have the ability to provide a public jar and still prevent you from redistributing

[shell robin]

😅 looks like an example I've seen in the docs, thank you

[icy beacon]

First of all: This is a byte field and not an integer

[smoky oak]

so do i put a 7 in there? or a n where n is the number of previous existing bytes

[sterile token]

Yes i know that, that why license or ToS exists to setup rules on it

But in theory you cant be punished for redistributing something that is already public, do i explain my point?

[tender shard]

Why not just use the actual nms packet‘s constructor, then you dont have to deal with any stuff like this

[lost matrix]

Next: Those indicies do not correspond to the packets fields but the index inside the wrapped metadata.

[icy beacon]

yeah you can. you can't resell my phone if I left it in a cafe

laws enforce that you can't

cuz i know neither

    dataValues.add(new WrappedDataValue(15, byteSerializer, armorStandTypeFlags));

    // Write the wrapped data value list into the packet
    packet.getDataValueCollectionModifier().write(0, dataValues);

    // done
    return packet;
  }

[sterile token]

Is that native packets?

[lost matrix]

Nope

[smoky oak]

looks like protocollib

and the conversation was about that sooo

[sterile token]

Yeah i was going to ask if was ProtocolLib or a custom lib

[lost matrix]

This is how the nms impl looks like

  private ClientboundSetEntityDataPacket createDataPacket() {
    SynchedEntityData data = nmsArmorStandBackbone.getEntityData();
    return new ClientboundSetEntityDataPacket(nmsArmorStandBackbone.getId(), Objects.requireNonNull(data.getNonDefaultValues()));
  }

[smoky oak]

that looks worse lol

[lost matrix]

You literally just pass your armorstand to the packet. Done.
I think this is easier.

[tender shard]

Its only 2 lines vs 30

[slender elbow]

just gonna throw my $.02 and say that that is usually code smell and an xy solution

[smoky oak]

well considering that code allows me to use protocollib and i still have no clue how to do nms :/

[tender shard]

I know, its not great

[smoky oak]

also its a player im resetting, not an armorstand

[slender elbow]

generally you should be using flags instead

[kindred sentinel]

How to make tab complete like this?

<message>

[smoky oak]

implements tabCompleter gives you a method that returns the list of stuff thats shown there

[tender shard]

Yes but some people want to have a plain old „blacklisted-regions“ setting, dont ask me why

[slender elbow]

bleh

"configure your regions correctly" - close as not completed, label as question 😛

[kindred sentinel]

yeah but in tab completer when you click on it it's replacing your argument, but this is not like a choice to complete it's like description of argument

• the color of argument yellow

[smoky oak]

oh idk then sorry

[tender shard]

Brigadier

Or any command framework that supports brigadier

[kindred sentinel]

oh ok thx

is there any way to disable minecraft command?

[tender shard]

Dont give permissions for it

[kindred sentinel]

[tidal kettle]

Hello i have a problem but i didn't understand the error ... can you help me...
https://paste.md-5.net/ewujutenot.cs

[lost matrix]

Recompile your jar

[lost matrix]

And from now on: never call any class/field "main" again pls

[tidal kettle]

the main.getConfig.get....

??

[quaint mantle]

Do like KitsPlugib

Or Kits

Or smth

Main is too ambiguous

[tidal kettle]

why lol

[quaint mantle]

Because Main does not mean anything

[tidal kettle]

for me main = class with onEnable and onDisable but ok

I'll take your advice

[remote swallow]

Why do i have 3 pings here

[lost matrix]

Because you are the renaming plugin master it seems

[remote swallow]

Same person i updated a plugin for earlier

[remote swallow]

Didnt say i wouldnt help, i just went to bed and didnt check discord

[tender shard]

naming the field main is fine, it's private anyway

[remote swallow]

I didnt write it lol

I just decompiled the outdated plugin and changed the nms

That's why it looks and is so horrid

[smoky oak]

can i ask for some more help? I'm doing this

initPacket(PacketType.Play.Server.ENTITY_METADATA); //this being an init method
packet.getIntegers().write(0,player.getEntityId());
addValue(8,Byte.class,(byte)0);//this being a helper method

and then send it to the player hit and the players observing said player, but apparantly its not doing anything?
Shouldn't telling a player 'ur not doing anything with your hand' make them lower the shield?

theres not even a console error

and im running on log = all

[tender shard]

is Server the same as Clientbound?

[smoky oak]

uh good question

[lost matrix]

Clientbound -> bound for client / sending to client

[smoky oak]

no, but there's no entity_metadata apparantly

[ivory sleet]

<Receiver>Bound<PacketName>Packet :)

thats how I remember it

[tender shard]

yeah but IIRC protocollib does it the other way around

thats why I asked

[ivory sleet]

haha thats so troll

[sterile token]

yeah another reason for not using asshole libraries

[tender shard]

yeah lol

[tender shard]

ok that means Server is Clientbound

[ivory sleet]

now idk if thats how I would describe it but yea plib is yikes

[tender shard]

agree

[lost matrix]

You cant just do this for an existing player. It would result in every single metadata value being overwritten.
All metadata values of the actual player need to be copied first. After that you can modify them.
But be aware that every little change in a players metadata will result in a new meta packet being sent by
the server, resulting in your packet being overwritten again.

[smoky oak]

so you're saying it didnt actually hit the player, or you saying I've been deleting metadata accidentally?

[lost matrix]

Your metadata packet is probably so ridiculously invalid that the client just ignored it.

[kindred sentinel]

Do people create local chat using

for(Player player : Bukkit.getOnlinePlayers()){
    Location playerLoc = player.getLocation();
                        if(playerLoc.distance(sender.getLocation()) <= chatRadius){
                            player.sendMessage(message);
                        }
}
```?

[worldly ingot]

The recipients list of the chat event can be altered, although I'm unsure if that's still the case in modern versions with chat signing

Also, distanceSquared() > distance() to avoid a square root operation

[river oracle]

not a big fan of square root choco?

[worldly ingot]

It's just unnecessary and not fast

[river oracle]

personally I think its fun to make those crazy ass numbers

[river oracle]

Its kinda crazy how bad computers are with decimals

[ivory sleet]

well we arent much better

[worldly ingot]

Just square root computations because there aren't any specific instructions on it on most architectures

[kindred sentinel]

So what other option do people use?

[worldly ingot]

I mean you can try it. It may work

If not, then yes your only option is to do what you proposed

[river oracle]

a little bit is all that counts

[kindred sentinel]

I'm not sure that i can understand what you meant

[ivory sleet]

:>

[livid dove]

Tiny side project go brt

[lost matrix]

Qeue up all messages and as soon as a player gets near another player, you simply
dump all messages you havent read from him because of distance.
Use a scheduler every tick to check the distance of each player to everyone else.

[lost matrix]

Pretty neat

[river oracle]

wouldn't it be easier to check within a players radius every message instead of every tick?

[lost matrix]

You cant dump the messages this way

[river oracle]

why would you want to dump them though?

ig if you want true local chat history

[lost matrix]

And you would really want to read 50 messages you had nothing to do with, dont you?

[valid burrow]

i keep getting this error for too many chas in a prefix but how is this "§4§l[Owner] §4" more then 16 chas

am i just dumb

am i missing something

[tender shard]

Its basically equally fast on modern CPUs

[worldly ingot]

You're assuming modern CPUs

[tender shard]

Yeah well i think modern is like last 15 years or so

I only tried on my i7 9700k and m2 max so yeah no clue about otherd

[livid dove]

Next job is an inventory menu with a central activate button and 8 surrounding icons that cycle through X symbols (one cycle per click) to do adresses to other portals :L

[tender shard]

imho using distanceSquared is unncessary especially for the chat

[livid dove]

imho distance squared not mattering in the modern day and age is fair, but it doesnt hurt when we're dealing with a single threaded duct tape machine that we call a game.

Every little helps as they say in tesco lol

i.e. if someone signs off their letter with a curly fancy f rather than a normal f, then who the hell is gonna complain its "unnesecary" ? lol

Its like when folk go OTT with the "Enterprise code" issues.

Once had a guy get upset because I javadoc'd one of my plugins fully

Like, my brother in code, I decided to add a little extra effort in, why are you mad xD

[valid burrow]

anyone got a clue?

[ivory sleet]

what version ru on

[valid burrow]

i know that 1.8 limits characters

BUT THERE IS NOTHING THATS 30 CHARACTERS LONG

LIKE

[livid dove]

Someone do the funny how old is 1.8 comman d

[young knoll]

Someone get the quake 3 devs

https://m.youtube.com/watch?v=p8u_k2LIZyo&pp=ygUYZmFzdCBpbnZlcnNlIHNxdWFyZSByb290

[valid burrow]

it says theres something 30 characters long and i have no idea where

like

it doesnt exist

[kind hatch]

Don't use 1.8 ¯_(ツ)_/¯

Those limits were removed in later versions.

[valid burrow]

i know

i like the new versions too

[tender shard]

yeah but I doubt that it's actually faster at all

[valid burrow]

but i also like 1.8 pvp and i like making plugins for that too x)

[tender shard]

the code only gets more messy

[valid burrow]

where does the data for the teams get saved

is there a way i can delete all existing teams

[tender shard]

I'll just run JMH and check whether distanceSquared is actually faster. Should take 33 minutes

[valid burrow]

i think that might be causing the problem that theres still a team existing with too many chas

[wild mica]

What should I use instead? https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/material/class-use/Redstone.html

[river oracle]

all usage of MaterialData is deprecated and subject to removal. Use BlockData.

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/data/type/RedstoneWire.html

[tender shard]

guys look at this https://github.com/coordinates2country/coordinates2country/tree/main

isn't that kinda a genius way to turn coordinates into country?

it just uses a grayscale image and then uses that to get the correct country

[wild mica]

Redstone class has button, hopper...

[tender shard]

AnaloguePowered

i think

or Powerable? sth like that

[river oracle]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/data/Powerable.html

[tender shard]

yeah Powerable are the "end consumers" of redstone, AnaloguePowerable are the wires etc (things that don't just have yes/no power, but a value between 0-15)

[lost matrix]

Ah.. was about to do the same...

[river oracle]

kinda crazy how long jmh benchmarks take

I did one the other day that took an hour and a half

[quiet ice]

I mean that is the idea

[river oracle]

ik I just didn't expect them to take that long

I thuoght maybe like a couple mins per not basically 10 or more minutes per

[wild mica]

Actually, I want to control the blocks that the player can interact.

[river oracle]

PlayerInteractEvent Plus Material check?

you don't even need block data for that

[wild mica]

Yes, but I want to control the redstone materials it can interact with.

[tender shard]

do it too, maybe we get different results

[lost matrix]

Already on it 😄

[tender shard]

how does your code look like though? we should be using the same i guess

if anyone else is bored: git clone this and gradle jmh https://github.com/mfnalex/Bench-DistanceSquared

[lost matrix]

Different testing methods might be more beneficial

https://gist.github.com/Flo0/007f86d5599f9d2ce6ae48c49338fdf2

[valid burrow]

how can i get the team a player is in

[lost matrix]

Ah ok so you get the invocation time per 1k and i the throughput

[tender shard]

yeah I thought maybe it's easier for JMH if the method takes longer than 0.0000000000001 second lol

[lost matrix]

But my result look pretty conclusive currently...

[tender shard]

Benchmark                         Mode  Cnt     Score    Error  Units
DistanceTest.testDistance         avgt   25  1645,770 ±  4,010  ns/op
DistanceTest.testDistanceSquared  avgt   25  1635,375 ± 11,381  ns/op

exactly the same

well almost

[lost matrix]

i would be sceptical on this one

[tender shard]

why?

[lost matrix]

Increase the number of positions and change the setup level to @Setup(Level.Iteration)
You are burning the same numbers into the cpu cache.

[tender shard]

the number of positions?

[lost matrix]

Yes, and change the positions every iteration

[tender shard]

it does that

[lost matrix]

Benchmark                          Mode  Cnt    Score    Error   Units
DistanceOverhead.distance         thrpt   10  471,200 ±  5,791  ops/us
DistanceOverhead.distanceSquared  thrpt   10  582,115 ± 10,796  ops/us

But for me it comes down to very similar results.
Squared is only slightly slower.

I mean still ~20% slower

[tender shard]

squared is slower?

[lost matrix]

Yes 20%

Wait

Huh?

Ok this needs a more intricate benchmark. brb

[worldly ingot]

That's literally impossible

distance() calls distanceSquared()

Unless you wrote your own impl

[lost matrix]

Well we had a more low level impl. Maybe there is some cpu magic that detected a vector distance calculation
and uses some specialized instructions for that. But now im curious.

[tender shard]

I'll now run it again with @Setup(Level.Invocation), so caches cannot have any impact anymore

[lost matrix]

Ill do two tests. One with volatile primitives

[tender shard]

here's my updated version that, like spigot, just takes the return value of distanceSquared and throws it into Math.sqrt https://github.com/mfnalex/Bench-DistanceSquared/blob/main/src/jmh/java/test/DistanceTest.java
It also creates new random doubles for each single iteration (so a loooooot of times)
and it also compares distanceSquared and distanceSquaredStandalone (which doesn't use a "nested" method)

[lost matrix]

Be careful with Invocation levels. Only makes sense if your tests last beyond 1ms

[bleak nacelle]

Is it possible in minecraft spigot to simulate ball moving?

like when looking from the sky

it will look like football is moving

20 ticks per second

[lost matrix]

PS:

  @Param({"50000"})
  private int numberOfElements;

🙂 Might not be useful here but is always a good idea to track

[livid dove]

Or hear me out, it won't make a difference so it doesnt matter? Maybe some people dont wanna work with squared roots as they are stinky to debug? Maybe some people hate using the Math methods or maybe I they are just scared of Squares (and, like cultured developers, love hexegons and the humble octogon more).

We have 2.4 billion seconds in an average life time, use em to make cool stuff rather than prove a point that , in the grand scheme of things, doesnt make a difference eitehr way :L

[tender shard]

I changed it to Iteration

[slender elbow]

smile's test is measuring throughput and the score is higher, see ops/us

[kind hatch]

Should be more than possible with Display Entities and a resourcepack.

[lost matrix]

Ah you are right

Facepalm

[slender elbow]

i mean that's still a good measure

just take the inverse :kappa:

[livid dove]

But was the measure squared?

lel

[tender shard]

for me it was basically equally fast

1645 vs 1635

[livid dove]

Excelent

job done

its fine

[tender shard]

let us be, it's interesting

[lost matrix]

But that doesnt pass the reality check for me...

[tender shard]

maybe it's m2 max magic

I'm running it again with Setup set to Iteration

[livid dove]

How about a compromise. If you carry on with it @lost matrix has to make a new thread guide on the topic 😉

[tender shard]

that's ok

[livid dove]

Well volunteered smile

[lost matrix]

no?

[livid dove]

lol

Too late

[lost matrix]

[tender shard]

[bleak nacelle]

[lost matrix]

jokes on you, im an undecent, imbecile pleb

[livid dove]

YES NEW THREAD HERE WE GO

Give Mfnalex credits in it 😉

[tender shard]

are you using gradle while throwing all logic into subprojects {} or what?!

because that is the definition of imbecile

i really stopped hating gradle but the kotlin-dsl thingy is really bugged in intellij

[lost matrix]

You are doing that, dont you...

[tender shard]

nope! I use separate buildSrc scripts even for stuff like spigot-dependency

[lost matrix]

Ok i dont think this makes sense with the average time setup

Benchmark                         (numberOfElements)  Mode  Cnt    Score    Error  Units
DistanceOverhead.distance                      50000  avgt   10  230,759 ± 15,473  us/op
DistanceOverhead.distanceSquared               50000  avgt   10  238,201 ± 19,281  us/op

[tender shard]

see? I got nothing to hide https://github.com/mfnalex/PAPI-Replace

[tender shard]

why not?

[livid dove]

Witgh the error it makes perfect sense

[valid burrow]

okay maybe something else is wrong here i cant even connect when i delete every single plugin from the server it still trows that error what else could it be

[livid dove]

There is an over 10000 overlap

[lost matrix]

How is this your full build.gradle file?

[quiet ice]

the buildSrc folder?

[lost matrix]

Was this about the closed zip stream?

[valid burrow]

about the character maximum

i took down every plugin and it still trows that error

[lost matrix]

Ah

[tender shard]

because I iknow how to properly structure gradle builds lol

[valid burrow]

what do i do at this point

pray?

[lost matrix]

This just means its stored somewhere regardless of plugins. Maybe in a scoreboard or something.

[valid burrow]

i ran something that shouldve cleared all existing teams

where would that be stored? can i manually delte it from a world file or somethng?

cause its getting really annoying

finally

i found it

incanse anyone ever needs to

its located in data/scoreboard.dat

[tender shard]

?paste

[undone axle]

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

[tender shard]

i now used the ALL option for the benchmark annotation @lost matrix
https://paste.md-5.net/cuqodafade.java

as expected, distance is the slowest, but distanceStandalone is only a tiny bit faster than squared

so that means, the most significant overhead isn't Math.sqrt but actually the nested method call lmao

@worldly ingot isn't that funny

[slender elbow]

choco is funny sometimes yeah

virtual dispatch bad

/jk 🤓

[tender shard]

choco should change his name to chicken

[slender elbow]

McFly

[tender shard]

1.21 gigawatts

[lost matrix]

Yeah i came to the same conclusion.
Would be interesting if we could start an jmh instance on a running server to see the actual overhead.
But this is honestly so much better than i believed it to be. I was under the impression that it would 2x the
calculation time.

[tender shard]

Yeah distanceSquared is overrated

At least today

Would be interesting to run this in kvm with as little passed through cpu flags as possible

[quiet ice]

That being said people must not ignore the fact that performance is stacking. A bit of slow code on it's own isn't bad but when it is bundled with other slow code it actually gets slow

[tender shard]

Yeah but normally you dont run it millions of times per second if you only use it to code a local chat plugin

[lost matrix]

True. But we are speaking about millions of invocations per tick here before a noticable difference can be seen.

[tender shard]

Because that’s how we came up with this lmao

How to waste time 101

[quiet ice]

I mean given that we are only working with primitives there is no serious performance impact

[tender shard]

Benchmark distanceSquared for a fucking chat plugin

[quiet ice]

Primitives are really really fast

Objects are fucking slow

[tender shard]

My neighbour is pretty primitive and he‘s quite slow

His name is Marvin

but not on purpose

[lost matrix]

[lost matrix]

Same. And im in the middle of munich so a ride could take me pretty far if i wasnt careful.

[worldly ingot]

but muh precious clock cycles

I've been C++ing too much lately

[tender shard]

we can make a deal. a compromise

class Location {
  // Protects Choco's precious clock cycles and mfnalex cannot complain about readability anymore
  public boolean isDistanceLessThan(Location other, double distance) {
    return distanceSquared(other) < distance*distance;
  }
}```

[lost matrix]

Ive seen a video from some C crack who said to not use if clauses anymore to save clock cycles

[candid galleon]

branchless programming does exist

[river oracle]

what else are you supposed to use

[lost matrix]

Thats what he was on about, right. Branchless programming

[tender shard]

did somebody mention crack

[candid galleon]

[lost matrix]

no, bad alex

[candid galleon]

it's generally not worth using unless you know what you're doing

https://www.youtube.com/watch?v=bVJ-mWWL7cE

[worldly ingot]

I mean jumps do use quite a few clock cycles 👀

[candid galleon]

that vid helped me learn about it

[lost matrix]

It makes the code so fking painful to read as well

[worldly ingot]

but yeah, unless you're writing software in the 1960s and trying to send something to the moon, you don't have to follow that technique lol

[tender shard]

reminds me of the time when we did stuff like that only to avoid using semicolons

[candid galleon]

if you're coding in java you shouldn't be worrying about that kind of optimization

brooooo why can't we use external emojis

[river oracle]

you can if you boost

[quiet ice]

That technique is actually more and more relevant today

[worldly ingot]

[candid galleon]

have yall seen the java programmer that tried out python

It took me a bit to write proper pythonic code

[tender shard]

avoiding if statements?
Here's a full featured configurable death chest plugin that only uses 15 semicolons (minus imports)
https://github.com/GodCipher/the-cipher-project/blob/master/src/main/java/we/are/project/cipher/AngelChestListener.java

[candid galleon]

only 31 lines

:poggies:

[tender shard]

it has more config options than actual lines of source code lol

[candid galleon]

should just import *

[lost matrix]

Are you really coding if you dont have a horizontal scroll bar?

[tender shard]

no ofc not, but the rules were "everyone must use no more than 3 semicolons per line, and use a maximum of 15 lines in total"

[candid galleon]

i've been coding wrong my entire life! all those lines wasted

[lost matrix]

We should host some coding challenges here in spigot 🙂

[tender shard]

yeah

but with a caveat

[river oracle]

Coding Challenge write a basic plugin and following OOP correctly

[candid galleon]

99% of people fail!

There is no crown truth to this.

[river oracle]

Gotta have a longer time limit if this is gonna be the case. lmao

[lost matrix]

Ill write a gradle plugin that simply uses a pom file.
Then my gradle file will have 2 lines

Things within the meaning of the law are only physical objects.

bad translation

basically it says " a computer program is not a thing because you cannot touch it"

[river oracle]

I see

[tender shard]

same like water, unless it's physically "contained" within a container like a glass

[candid galleon]

What did one interface say to the other?

"Let's keep in touch, but don't call me, I'll call you."

How do you compliment an OOP programmer?

Tell them they have class.

[lost matrix]

The challenge should be a plugin which allows player eine Anzeige nach StGB § 223 Körperverletzung, if he attacks you.

damn I missed the opportunity to include "pushing" it too far, too

[candid galleon]

you're really pushing it

[lost matrix]

Well, get remove contains are pretty much equivalent, no?

For tables

[tender shard]

probably, yeah. we'll see

[tender shard]

huh it's slower for 500 than for 5000

[lost matrix]

Yes. But im only testing a single key. Let me also iterate over all keys like you do.

[tender shard]

imagine jvm pulling a volkswagen and goes into turbo mode when it detects a benchmark

[lost matrix]

XDDD

[tender shard]

JIT compiler: "contains? sure, return true, it's probably there"

[lost matrix]

Quick, compile everything to binaries and use a GraalVM, he is doing a benchmark

[lost matrix]

lol even better

[tender shard]

is it called Graal because of the holy grail?

[lost matrix]

no idea

[tender shard]

i always have to think of indiana jones 3 when I hear "graalvm"

[lost matrix]

dude what

[tender shard]

have you not seen it?

he's looking for the holy grail but then nazis capture his father, sean connery

[lost matrix]

Was this the face melty ij?

[tender shard]

so then he only tries to find his father but to do he actually has to get the holy grail because his father was shot and only be healed through the grail

the nazis are stupid and choose the wrong grail (a shiny one) and then the main nazi dies

indiana jones is smart and chose the most ugly grail because jesus made it himself (and apparently he wasn't very good at making grails)

that's indiana jones 3

Here its scaled up

[tender shard]

but this is still my all time favorite scene of all indiana jones movies https://www.youtube.com/watch?v=kQKrmDLvijo

[lost matrix]

Ive seen this so often

[tender shard]

best scene

[lost matrix]

[tender shard]

lmao

and then someone steals the bad guy's sword

[lost matrix]

How is the benchmark going?

[tender shard]

does it automatically change the "numberOfElements" param?

1 min left

[lost matrix]

Yes. It runs a whole benchmark for each parameter

[tender shard]

ah nice

[lost matrix]

  @Param({"500", "5000", "50000"})
  private int numberOfElements;

[tender shard]

I gotta use that next time too

[lost matrix]

Its really nice if you need to plot the time complexity of a collection.
Simply increase the elements and you get nice plottable data

[tender shard]

okay it's a confusingly long https://paste.md-5.net/udajevekeq.makefile

[lost matrix]

You ran it for all modes?

[tender shard]

yes

check out remove / avgt time

the normal map is twice as fast

but the other things, the difference isnt that big

DistanceTest.remove_ConcurrentHashMap                                         avgt       8      2802,612 ±    60,472   ns/op

[round finch]

if n gotta be 0? when what is the point

[lost matrix]

I guess you dont have to check for locks if you simply want to call contains

[round finch]

10 + 0 = 10

10 = 10

seems pointless variable

You know what would be nice? If someone remade the old lucas arts adventure games like monkey island or manic mansion as mc adventure map

[tender shard]

Haven’t played those

[lost matrix]

[tender shard]

Is that available for scummvm

[lost matrix]

pardon?

[tender shard]

Is it a point and click adventure?

And is it 30 years old?

If yes, then yes its available for ScummVM

[lost matrix]

Yeah, its pretty much not

[tender shard]

I see

How dare you

[lost matrix]

But i almost started writing a deep rock galactic type of plugin for mc.

*on that note

[quaint mantle]

If I want to write a custom functionality for banning, should I make another class for that

like

new BanActionThing(args).issueOn(target);

[gilded granite]

is there any PlayerBanEvent?

[round finch]

https://hub.spigotmc.org/javadocs/spigot/

[lost matrix]

If you have to ask this question then there is a good chance you should create a ton of new classes.
Some could look like this:

• BanManager
• Ban
• BanType
• BanListener
• BanCommand
  etc

But i would def not do

new BanActionThing(args).issueOn(target);

More like

OfflinePlayer player = ...;
Ban ban = new Ban("reason", BanType.TEMP, Duration.ofDays(7));
BanManager banManager = yourPlugin.getBanManager();
banManager.applyBan(player, ban);

[quaint mantle]

hmm

I was thinking about something like a

BanAction

[glad prawn]

Nah create your own then call after u ban him

[quaint mantle]

I might just like

hm idk

new BanScreen().showTo(Player)

lmfao

[quaint mantle]

I have my own little punishment system already

now im just making the "front-end" stuff

[lost matrix]

This looks like a pointless object creation

[quaint mantle]

bruh

yeah ig it is

[lost matrix]

new Something().call(somethingElse);

Creates a temporary object for no reason

[quaint mantle]

I also have this

I just like the more static typed things

instead of

getConig().getString("path.path.path")

[lost matrix]

Which is perfectly valid

[quaint mantle]

I made a registration handler for these so users can edit them

[quaint mantle]

well i dont like it lol

I feel like it's just too prone to mistakes and stuff

[round finch]

or you could make ur code look nicer

[lost matrix]

No, i mean preferring staticly typed value access is perfectly valid

[quaint mantle]

oh

yay lol

[worldly ingot]

You could write constants for your strings instead

[tender shard]

Make-up, smoky eyes, etc

[worldly ingot]

For common paths and values it's best to have them all in one place anyways

[quaint mantle]

no

[round finch]

are you talking about urself? confusion

[quaint mantle]

each one has their own implentation

[tender shard]

Sometimes

[quaint mantle]

Idk if this is bad or good I need opinions

[lost matrix]

smoky eyes 😏

[round finch]

you remain to be an enigma

[quaint mantle]

the only costants I have are permissions

constants

which is an enum lmao

I've never done something like this before

[round finch]

my Ai pf has deepy eyes thb

[quaint mantle]

but it makes it so server owners can set their custom permissions

[young knoll]

Don’t smoke eyes

[round finch]

dont smoke using eyes

[worldly ingot]

Two questions

1. Why doesn't your withPermission() method just accept a CommandPermissions instance?
2. Why are you using an enum to begin with? You can use String constants so you don't have to call .getPermission() every time

[quaint mantle]

withPermission is CommandAPI

and I used an enum rather than String constants is because of how I register classes

[sweet kiln]

Hello! I'm trying to spawn a mob called 'ALLAY' on 1.20.1. But I'm having problems, the problem is this. When I enter the server it spawns, only there comes a time when it stops spawning and not even restarting the server can work. Can anyone help me?

[quiet ice]

That array is funky

Ah because this isn't java

[sweet kiln]

Kotlin

[quiet ice]

The only thing I think may cause this is the fact it despawns but that still makes little sense

[sweet kiln]

I found a bug

[glad prawn]

found

[bold gorge]

I know this isn't a very development issue but I think it would be best to post something like this here? idk shoot me if I'm wrong

What's the best way to advertise a spigotmc library?
I'm making a menus library named Woody and it has some very nice features a lot of libraries don't have (and more creative coming)

issue is advertising and I want to spread the library efficiently.
ping me when responding with some advice

[coarse finch]

hey! im working on a feature for an anticheat, where it tries to detect if someone is spoofing their client. here is my code: ```java
public boolean isLikelySpoofingBrand() {
final String brand = this.getBrand();
final String lunarClientRegex = "^lunarclient:v\d+\.\d+\.\d+-\d{4}$";

return (brand.equals("vanilla") && !this.isVanillaMath()) || // Vanilla doesn't have fast math
        (brand.matches(".*lunarclient.*") && !brand.matches(lunarClientRegex)); // Some clients spoof lunar incorrectly

}```im wondering if there is other methods to detect if someone is trying to spoof their client?

[remote swallow]

Add a config option too

Incase it isnt maintained but new popular clients exist

[ivory sleet]

Its rly hard to detect client spoofing tho

Cuz like, smart devs will make it unnoticeable

[coarse finch]

this is just used as a warning

when someone joins, or you view their profile, it they are suspected for brand spoofing it says (likely spoofed)

[coarse finch]

im banking more on dumb people

like with fastmath

ive had lots of players on my server with a brand of vanilla, yet they are using fast math

or people with outrageously fake lunar brands

[dark jolt]

This is gonna sound stupid but for Command Execution the one thats not the main one should those be classes in stead of .java

[hazy parrot]

what

[drowsy helm]

huh

all your code will be .java until compiled

[young knoll]

Wtf is fast math and how does one even detect that

[drowsy helm]

and all of those files will have a class in it

[dark jolt]

alr thank you I had a blank moment for a second that I been coding my plugins wrong all this time

[coarse finch]

fast math is less accurate sin and cos calculations (not even beneficial on decently modern hardware)
simulation. simulate a client with & without fast math, and see which is closer

[young knoll]

I see

[quaint mantle]

Ok I have more time to explain now, so

1. I'm using CommandAPI, an API that I did not make. Here's a link to the API: https://github.com/JorelAli/CommandAPI

2. I wanted the String for the permission to be configurable, and I also have multiple groups of permissions. For example "CommandPermissions, PunishmentPermissions". And I want the server owner to be able to change the permissions. Another reason I didn't do that was because I didn't want to use reflection

[candid galleon]

Why do you want permissions to be configurable?

[drowsy helm]

yeah seems like a waste of time to make them configurable

thats something a permission system is supposed to do

[opal carbon]

ok but does anyone actually turn that on

[slender elbow]

fast math still exists? lol

[opal carbon]

also i dont think thats even a good check

iirc optifine reports as vanilla

[coarse finch]

It doesn't

[coarse finch]

Yes

[opal carbon]

who lol

[coarse finch]

Well for one, badlion automatically enables it, and second, people who don't know what they're doing

[opal carbon]

wow badlion is wierd

https://github.com/hibatica/AdagraPlugin/blob/master/src/main/java/me/hibatica/adagraplugin/duels/inventorymanager/DuelInventoryManagerListeners.java

I can't for the life of me figure this out.

If a player is in a duel, I don't want them to be able to move items out of their inventory as they'd be able to dupe duel kits.
also ik, amazing code

[stray nacelle]

why sending item update packet makes item in hand swing :((

[grizzled oasis]

How can i load itemstack as items to display into an achievement https://paste.md-5.net/uxazayuriw.bash (currently only supports items only name)

[livid dove]

So when doing right click interaction events, it continues to proc when holding (and most the time at least triggers more than once) and tends to fire off in pairs. This is nulifying an event where i wish to set on first right click, and nulify on a second right click if at the same location, has anyone bodged together awork around?

[tall dragon]

?interactevent

[undone axle]

The PlayerInteractEvent may be called once per hand. If you only want code to be executed once, you can check the result of https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerInteractEvent.html#getHand(), then decide functionality.

For example, only executing code if the main hand was used:

@EventHandler
public void onPlayerInteract(PlayerInteractEvent event) {
    if (event.getHand() != EquipmentSlot.HAND) { // * if the hand used is NOT the main hand:
        return; // do not progress past this point  |
    }
    // provide functionality
}

[tall dragon]

probably this

[livid dove]

Ahhh

also thank you cafebabe. Best botty boi

Hi im trying to provide this

But in this way its wrong any fix about for this?

[distant wave]

does anyone know how to get hand used in EntityDamageByEntityEvent and the item used?

[grizzled oasis]

the item in the main hand of the user

i would assume

[distant wave]

cant you attack with offhand?

[grizzled oasis]

no for what i remeber

[smoky anchor]

I don't think this is that easy
Throwing potions/shooting bow from off hand might trigger that event (idk by which entity)

[distant wave]

ye im checking if the damager was a player

id assume thrown potions would be the damager in that case

• you have EntityType.ARROW and EntityType.SPLASH_POTION

[smoky anchor]

well in that case it is always main hand
can't recall any instance of it being offhand

[smoky oak]

Is there a way to temporarily disable IntelliJ ordering of autocomplete? I'm creating a partial EnumSet and with non-alphabetical order keepint track is a bit difficult

[distant wave]

can i check for key in pdc like this? or do i need to store the namespacedkey instance somewhere

instance is the plugin instance

[smoky oak]

i hate how it looks but i think that works

[distant wave]

just want to make a quick wrapper so idont have to write the long lines everywhere

[smoky anchor]

You do not need to store it
It will work like this as well
Just keep in mind that it may be using a bit more memory/be slower

[smoky anchor]

I know of at least 2 pdc wrappers
mine and I believe alex's lol

[distant wave]

i dont want ot use external dependencies

[smoky anchor]

well then
I hope you never want to do NPCs

[distant wave]

i mean atleast not a lot of them

[smoky oak]

What's the simplest way to test if it's day/night? I refuse to do math using world.getTime if possible since it returns total time

[echo basalt]

That's fine

[echo basalt]

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

:)

[smoky oak]

nevermind, theres different times lol

[echo basalt]

just % 24000

and do a range

[distant wave]

btw how would you make a custom persistence data type? should i use classic serialization for it?

[smoky oak]

you've two options

the good one and the insane one

Illusion or alex, dunno which of em, made a PDC library that takes any data type if i remember correctly, thats the normal solution

alternatively you can just turn a object into a byteOutputStream, read that as a string, and shove said string into the PDC

[distant wave]

so classic serialization

[smoky oak]

I would really recommend using the library :P

[echo basalt]

was alex

I barely make public libs

and all of my public libs are either on my search index or my gist

[distant wave]

i wrote this simple thing, it should work right?

[echo basalt]

I mean

There's probably a better way

Like the object's yours

You can probably make a byte buffer and write the contents yourself

[bleak nacelle]

why dns takes too long to set up

[onyx fjord]

You mean the propagation?

[lilac dagger]

i had a dns that took a whole day to propagate

and the weird thing was that some friends had access to it

[smoky oak]

takes like 1-2 days

[bleak nacelle]

yes

[onyx fjord]

because of caching etc

but you can always flush manually

[bleak nacelle]

isp also caches so its impossible to login if you dont change ip

it takes time

[onyx fjord]

then use a different dns server

you shouldnt rly use your isps

[bleak nacelle]

i switched to cloudflare warp

[onyx fjord]

1.1.1.1?

[bleak nacelle]

yes

is the dns server and dns resolver is the same thing?

[echo basalt]

I had some issues with call of duty and cloudflare warp

[wary remnant]

You can manually flush cloudflares DNS cache

Reading a file from my jar using Files.readString(path inside jar file) always replaces § with § (it's not like this in the jar file), using UTF-8 for both reading/writing

sure. but as far as i know you will need to define your own list of "bad" potion effects

afterwards you can just loop through and remove them

Okey, thanks!

[native bramble]

want to make inventory rollback plugin and have a question: which is the best way to save the data?
i need to save players info(inventory, location, health, exp and other) when player join, quit, world changes and deaths.

It is plugin InventoryRollbackPlus which saves data in this way:
/backups/deaths/<uuid>/<time_in_long>.yml

But is it a better way to save data? Maybe with sqlite?

[wary remnant]

There are many ways. You could save the (gzipped) NBT data

[quaint mantle]

use nbt

or sql whatever you like lol

you can even use scoreboard

[native bramble]

ok

[ivory sleet]

@quaint mantle u've done modding right? (fabric)

[quaint mantle]

yes

[quaint mantle]

what you want?

[ivory sleet]

so lets say I wanna add some "instance variables" to both LocalPlayer objects and ServerPlayer objects while they are valid in session

[quaint mantle]

tell me it in yarn names

[ivory sleet]

I thought of using another class just and add some mixins here and there, but I assume there are better ways

ugh let me see

[quaint mantle]

you can easily implement a class and add new fields, methods into whatever class you want using mixins

[ivory sleet]

yeah but then comes the issue

[quaint mantle]

look into https://github.com/2xsaiko/mixin-cheatsheet

[ivory sleet]

when I want to write and read

as well as handling respawns

[quaint mantle]

thats mixins

[near mason]

[ivory sleet]

yeah I thought I could inject a data thingy into the dimension data storage

[quaint mantle]

yes you can
