The scheduler isn’t bad

[opaque scarab]

Is there a way I can get the type of tool a block needs to be mined with, efficiently?

[young knoll]

You just need a plugin instance

[inner mulch]

i dont know, maybe a switch(material) and you set it up for every block in the game

[lilac meteor]

I only knew of sleep from when I messed w vanilla multithreading when I was in school

[pseudo hazel]

im assuming they mean efficient to write, not efficient for the computer

[young knoll]

There are tags which tell you which tool to use on a block

[lilac meteor]

didnt know Bukkit had such weird stuff going on when you use traditional multithreading

[pseudo hazel]

blame mc

[young knoll]

There’s also isPrefferedTool in the block class

[opaque scarab]

Dude thank you so much

[inner mulch]

switch case is nice too :D

@echo basalt

now that's what I call code

I'm ready to be paid by the character

[young knoll]

Paid by the byte

[lilac meteor]

okay.. so now im running into the issue of being able to pass in a plugin into the runTaskLaterAsynchronously function

since my handler is in its own class

[edgy crystal]

anyone knows, how i can set the port on theholywaffel ts dependency?

config.setHost("000.00.000.00:0000"); (hiding mine)

config.setQueryPort(10011);
config.setFloodRate(TS3Query.FloodRate.UNLIMITED);

this doesnt work

[steep scroll]

I am trying to code a plugin that makes the last player to get hit or spleefed to get kill credit(I do not know where to start )

[worldly ingot]

Why don't you just call the nested class EventCaller?

[ivory sleet]

ru u making a web api?

where u use java for backend?

ah

s u're making a java wrapper lib

there are many ways to do this

well basically u wrap rest/graphql calls

make java representational classes of REST json objects

have u used jda?

yeah well u probably wna do sth similar to what they do

[lilac meteor]

I used the runTaskLaterAsynchronously function with a delay of 1
now its still occasionally happening, but it seems that on the occasions that it would ORIGINALLY function properly now throws an error

java.lang.IllegalStateException: Asynchronous block remove!
        at org.spigotmc.AsyncCatcher.catchOp(AsyncCatcher.java:14) ~[spigot-1.20.1-R0.1-SNAPSHOT.jar:3836-Spigot-3374045-08ec344]```
and the line of code from me that this is triggering on is the only one in this function

void replantCrop(Block blockBroken, Ageable targetCrop) {
blockBroken.setBlockData(targetCrop);
}

[ivory sleet]

no

but u wrap it

[lilac meteor]

    @EventHandler(priority = EventPriority.HIGHEST)
    public void BlockBreakHandler(BlockBreakEvent event) {

        //TODO: Add permissions for who can use the plugin
        Player actor = event.getPlayer();
        //get permissions
        //if not allowed, ignore

        //Allow user to ignore when pressing shift
        if (actor.isSneaking()) { util.debugMessage("Player sneaking, handler ignored"); return; }

        //If block is not a crop, ignore
        Block blockBroken = event.getBlock();
        BlockData blockData = blockBroken.getBlockData();
        if (!(blockData instanceof Ageable)) { util.debugMessage("Block is not a crop type"); return; }

        //Complete the final checks of when this handler will control the event
        Ageable targetCrop = (Ageable) blockData;
        int currentAge = targetCrop.getAge();
        int maxAge = targetCrop.getMaximumAge();
        if (currentAge < maxAge) { util.debugMessage("Crop was too young " + currentAge + "/" + maxAge); return; }

        //https://bukkit.org/threads/asynchronous-block-remove.202491/
        //SET PRIORITY TO LAST????

        //Cancel event as to prevent the block breaking after replanting
        event.setCancelled(true);

        //Drop the items that would normally drop
        dropAllItems(blockBroken.getDrops(), blockBroken.getLocation(), blockBroken.getWorld());

        //"Replant" the crop, really just setting the age back to 0 to look like
        targetCrop.setAge(0);

        //Need to wait a tick or two before replanting to let any break event misfires to pass
        Runnable replantSequence = () -> replantCrop(blockBroken, targetCrop);
        BukkitScheduler scheduler = Bukkit.getScheduler();
        scheduler.runTaskLaterAsynchronously(plugin, replantSequence, 1);
    }

[ivory sleet]

here is an example https://github.com/HypixelDev/PublicAPI/blob/master/hypixel-api-core/src/main/java/net/hypixel/api/HypixelAPI.java

[lilac meteor]

    void dropAllItems(Collection<ItemStack> AllItems,Location location, World world) {
        for (ItemStack item : AllItems) {
            world.dropItemNaturally(location, item);
        }
    }

    void replantCrop(Block blockBroken, Ageable targetCrop) {
        blockBroken.setBlockData(targetCrop);
    }

sorry for big code block, adding the async stuff is giving me even more grief than not delaying the replant

[ivory sleet]

whats so confusing

u fetch from the rest api

u get a json object

and then u turn that into a java object

[quaint mantle]

Hi , is good idea for make file scanner for making a simple anticheat ? a file scanner for cheat files !

[quasi berry]

Does someone know why this isn't properly saving to config.yml?

[lilac meteor]

@young knoll @sullen marlin any thoughts?

[quasi berry]

Line 51

[ivory sleet]

sure

yes in simple terms

but then for instance jda is complex

because it provides caching alternatives

custom executors etc

i dont like jedis

its just good as a quick jedis java test setup

[quaint mantle]

but i think server spoofer can stop this so Can i make a file scanner without stopping by server spoofer ?

[ivory sleet]

lettuce is better

[rare rover]

are skip lists poor for performance?

i need a thread-safe list

[ivory sleet]

define poor performance

hmm

ttl isnt time based tho

its just to avoid endless circularity

no?

[sullen marlin]

You need a syncronous task

Do you really need redis caching

Unless your API is slow and you have multiple servers it's pointless

Redis is just a complicated map

Honestly I don't you're at the scale where you need any caching

[steep scroll]

how to code spleef kill credit plugin

I want to check if a player is standing on a block that is broken by another player

[sullen marlin]

You probably don't need caching

Do your thing without caching

If you need it add it later

Why

How many is a lot

What does the API do

So 0.5/second

Your API can't handle 1 request every 2 seconds?

Sure

Or Guava cache

[eternal oxide]

I remember it was place not break that undoes.

[quasi berry]

Someone able to explain why this isn't working? It creates the config file but doesn't set the data

relevant main class:

    public void onEnable() {

        ConfigUtil config = new ConfigUtil(this, "syndicate-data.yml");
        getConfig().set("hello", "world");
        config.save();
    }```

relevant ConfigUtil class:
```public class ConfigUtil {
    private File file;
    private FileConfiguration config;

    public ConfigUtil(Plugin plugin, String path) {
        this(plugin.getDataFolder().getAbsolutePath() + "/" + path);
    }
    public ConfigUtil(String path) {
        this.file = new File(path);
        this.config = YamlConfiguration.loadConfiguration(this.file);
    }

    public boolean save() {
        try {
            this.config.save(this.file);
            return true;
        } catch(Exception e) {
            return false;
        }
    }
}```

[ivory sleet]

think u might have to create the file also

on disk

unsure how exactly save() worked

CHM works just fine, no?

[quasi berry]

I'll give that a go, but the plugin generates the config properly upon running it

Just doesn't add the hello: world

[drowsy helm]

what click event

inventory click or player interact

but pretty sure you will receive all 25

[inner mulch]

how do i add dependencies into my project (apis)

[drowsy helm]

are you using maven or gradle

[inner mulch]

maven

[drowsy helm]

the api should give you a maven dependency just copy paste it into your pom xml

[inner mulch]

it is red :(

errors

[drowsy helm]

show it

[inner mulch]

<dependency>
<groupId>com.lkeehl</groupId>

</dependency>

errors

red :(

[drowsy helm]

the whole thing

and whats the error

[inner mulch]

idk thats why im here

[lilac meteor]

synchronous instead of async is what you mean right?

[drowsy helm]

we cant mind read lmao

how are you getting an error but dont know what the error is

[inner mulch]

the id version groupid is red

it just is not a depency of the project

[drowsy helm]

show your full pom xml

[inner mulch]

its not that its copied wrong

the name is red

not the pom xml stuff

[drowsy helm]

have you relaod maven

[inner mulch]

i didnt know that i need to reload it :)

thank you

how can a player stand on something that isnt there

and you are using player name

and then trying to convert it to a uuid

[steep scroll]

yes

[river oracle]

so idk if you are aware

but

if a player has the name, "Bob", that is not a UUID

[ancient plank]

Ex.
My username is: Adelemphii
but my UUID is: 501b25af-98c7-4807-8f4f-7d257a75d55d

[steep scroll]

aaa

I see

just fixed it thx

[sullen marlin]

Yes

[lilac meteor]

I decided that when the event triggers and that the replant should be done, it adds the location to a list of locations, then if that event is triggered again, it checks if the location is in the list and cancels the second event and returns if that is the case

so in short, I mutex the location
and I call a function to unlock it 2 ticks later

Hello, i want do a confirmation gui. How to do? When my player click on a button, Open the confirmation gui with callback ?

[gritty cradle]

hey yall can someone tell me how i can decrease the minimum height for fall damage using spigot api?

[buoyant viper]

u can probably? start setting their fall distance based off of ur own calculation @gritty cradle

like Player#setFallDistance or w/e iirc

[barren oak]

Hello. I want to make the building system where constructions is made out of multiply blocks, and contains various variables such as material and durability.
For example, when player places certain block, there will appear new construction, and when any of its block damaged, durability of entire construction will decrease.
Also i need it so player can upgrade the construction and demolish it.
How can i make it, with taking into account that there will be many of constructions, and they needs to be saved even on server restart?

i can provide an youtube video with example

[gritty cradle]

well I want it to make it so that the player gets fall damage regardless of how high they fall

like for example just falling from 1-2 block height will give fall damage

[hybrid spoke]

you would need to save them somewhere and either provide them or provide a constructiom creator

[barren oak]

thats the point, where i can save them?

[quaint mantle]

Whats a good website to find chars to use for font files in resource pakcs

[barren oak]

thanks for response anyway

[hybrid spoke]

wherever you want. on the server as files f.e.

[tacit drift]

show your code lol

[shadow night]

Lmao

[grim ice]

fast question - do you know something about obfuscation?

[tender shard]

i'm using allatori, why?

[tender shard]

one of my plugins lol

[grim ice]

allatori can be deobfuscated though

[tender shard]

everything can be deobcusfacted though

[grim ice]

yeah, but some are very hard to

e.g ZKM costs 250$, no one has ever deobfuscated it yet

currently

im not looking for the standard way of obfuscation

im trying to come up with a new method

something about linking the code to a user's device

in which the code wouldnt run if its in another person's device or something like that

[pseudo hazel]

what do you mean, on the MAC adress or somethin?

[eternal night]

[tender shard]

string encryptoin is completely pointless

[tender shard]

and then how do you want to sell this to hundreds of people?

by giving everyone a unique .jar or what lol

[grim ice]

Yes

i can make a jar generating mechanism or something like that

still, im very lost currently

[hazy parrot]

Again this convo

[tender shard]

it's useless

i just happened to have bought allatori anyway, so I use it, but it's literally pointless to invest any more time than just using whatever you already got

even thinking about your weird custom encryption is already a total waste of time you could better spend on adding some new features

[grim ice]

the people in my commuity

are the most annoying humans ever

[tender shard]

Then dont sell anything to them?

[grim ice]

you ever had a dedicated group of 200+ people just trying to make a copy of your work and give it away for free

out of spite

[grim ice]

they would bribe my customers to give them a version of it

💀

[tender shard]

Your plugin must be the best plugin ever made

[eternal night]

if you are going to deal with that group, your self made obfuscation or keylike checks are not going to stop them lol

[grim ice]

it isnt a plugin

[grim ice]

yeah it gives me such an ego boost

but still, this is reality

well its a mod

[tender shard]

I doubt that you can think of any better obfuscation than the people at allatori or other available obfuscators

[grim ice]

and its by far the biggest mod on the certain community im in

[grim ice]

True

but the thing is

what allatori and the other obfuscators did

just obfuscated the code

is there no possible way of like

ughh nevermind thats impossible

you cant have code being ran without the client seeing it

damn it

[tender shard]

PaaS lol

Sounds like a very bad idea

[quiet ice]

Packet analysis as a Service?

[tender shard]

Plugin

Or whatever

[grim ice]

its a client side mod

meaning it doesnt interact with the server

[tender shard]

I wouldn’t invest time into it

[grim ice]

so in short, its meaningless to pursue obfuscation any further?

[tender shard]

it doesn'T hurt to run allatori or similar on it if you have bought it already anyway

especially since you can tax deduct the cost of any available obfsucator

[grim ice]

i dont have allatori but there are so many free deobfuscators for it

[quiet ice]

Plugins as a service is doable but it is just about as easily reverse-engineerable in java space

[grim ice]

what even is that

[tender shard]

try to run this through a deobfuscator and see if you can get any useful code, and see what it produces. 100% it won't be even close to the source code on github

[grim ice]

aight

[pseudo hazel]

if you want code noone can see you shouldnt make minecraft addons

[warm light]

how can I set sound on skull with setNoteBlockSound?
anyone can give me an example code?

[vivid lion]

You need a block then check if block.getState() is instanceof Skull

If it is cast state to Skull

[warm light]

I am confused with NameSpaceKey

how to use that to setNoteBlockSound

[tender shard]

sounds use namespaced keys, e.g. minecraft:ambient.crimson_forest.mood

that'd be ```java
NamespacedKey.minecraft("ambient.crimson_forest.mood")

if you got sounds from a resourcepack, e.g. "mypack:some_sound" you'd do NamespacedKey.fromString("mypack:some_sound")

[warm light]

thanks

but where I can get the list?

[tender shard]

I just use /playsound and search through with tab completion

[warm light]

thanks again ;)

[tender shard]

the name is usually the same as in the Sounds javadocs, except that for example ENTITY_ARMOR_STAND_HIT becomes e.g. entity.armor_stand.hit

[warm light]

got it :)

[sterile breach]

hello, if I have a player open an inventory when one is already open, will it call the closing vent?

[sullen marlin]

Yes

[warm light]

ambient is the sound that the mob made normally right?

[onyx fjord]

yeah randomly while living i think

[short raptor]

In what situation could this produce null pointer exception?

Only if the UUID doesn't correspond to a valid player?

[echo basalt]

Bukkit.getPlayer returns null if the player isn't online

[short raptor]

Oh, okay

[echo basalt]

the .isOnline method on Player is somewhat useless as it's inherited from OfflinePlayer

[short raptor]

I misunderstood it, I thought it would return offlineplayers for any valid uuid

[echo basalt]

That's getOfflinePlayer

[short raptor]

Ok cool ty

[mortal hare]

lol i thought i was the only one who are this lazy and does this 😄

[undone axle]

Not verified? Upload screenshots here: https://prnt.sc/

[placid moss]

have you built the project

[echo basalt]

Yeah so you're running your project instead of actually building it

[placid moss]

why are the logs a jda bot

also are you using a build system? if not i recommend you use one (maven or gradle probably)

[eternal night]

you have to try-catch that

I mean, only really required around the .sleep call

https://www.baeldung.com/java-interrupted-exception

[umbral ridge]

It's not recommended to throw exceptions within the try-catch block and it's not a good practice

[kind hatch]

What in the name of?

[wet breach]

if it doesn't work the first time

do it the second time

[echo basalt]

wallah wtf

[wet breach]

not sure what that is for, but it seems just like an easy way to skip the first element

[kind hatch]

This is JDA's javadoc bot parsing code.

[kind hatch]

Ohhh, that would make sense now.

They have some weird element in their docs that they use to mark something. They must be skipping that one specifically.

[wet breach]

first setting, would be first element, the second one would move it to the next, and the loop would just advance it from there

[wet breach]

yeah was about to say, maybe the first element is just always some garbage thing

this is a common thing especially from the web develpment side of stuff

you would commonly skip the first elements lol

[kind hatch]

Don't know why they didn't just use :nth-child() instead.

Pretty sure JSoup supports those kinds of selectors.

[wet breach]

because that requires different method calls and would actually be slower

this is just one of those things where its a nice trick to skip the first one

its easy, doesn't hurt performance etc

[kind hatch]

Well my retrofitting hacks were working up till this point. :p
Guess I'm gonna have to rewrite this method since there is no weird elements in the spigot javadocs.

That and the structure is different between JDA & Spigot.

[mortal hare]

can someone explain why bukkit configuration api loads the file into deserialized string type

and then parses it through snakeyaml?

snakeyaml Yaml object allows you to read from input stream via Yaml.load()?

https://tenor.com/view/why-tho-cute-kid-gif-17937097

[kind hatch]

Probably because spigot was using a really old version of SnakeYAML for the longest time. They only recently updated it to something relatively newer.

[lilac dagger]

i've noticed it too, they added comments 😄

@Override
    public void onEnable() {
        ProtocolManager manager = ProtocolLibrary.getProtocolManager();
        manager.addPacketListener(new PacketAdapter(this, PacketType.Play.Server.NAMED_ENTITY_SPAWN) {
            @Override
            public void onPacketSending(PacketEvent event) {
                PacketContainer spawnEntity = manager.createPacket(PacketType.Play.Server.SPAWN_ENTITY);
                WrapperPlayServerNamedEntitySpawn playerPacket = new WrapperPlayServerNamedEntitySpawn(event.getPacket());
                WrapperPlayServerSpawnEntity spawnPacket = new WrapperPlayServerSpawnEntity(spawnEntity);
                
                spawnPacket.setUuid(playerPacket.getPlayerId());
                spawnPacket.setX(playerPacket.getX());

                event.setPacket(spawnEntity);
            }

it gives me java.lang.NoClassDefFoundError: error

[echo basalt]

The packet wrappers aren't included in protocollib and you'd need to shade them

[near mason]

wdym

i added it to pom.xml

do i add it to plugin.yml's depend?

[quaint mantle]

Fat jar

[young knoll]

You need to use the maven shade plugin

[near mason]

Failed to create shaded artifact, project main artifact does not exist.

[wise pumice]

add to your pom.xml maven shade plugin and execute goal maven package

[onyx fjord]

@near mason packetevents has wrappers built in

[tender shard]

paste your pom.xml

[tender shard]

mvn clean package should work fine

but why did you disable the dependency-reduced-pom?

also you gotta shade PacketWrapper

i think

[quaint mantle]

Remove provided scope from com.comphenix.packetwrapper

[young knoll]

Isn’t packetwrapper like

Really outdated

[tender shard]

I'd also update maven-compiler-plugin to 3.11.0 and maven-shade-plugin to 3.5.1

[tender shard]

from what i know, yes

[onyx fjord]

it is outdated so i recommend packetevents instead

or making your own wrappers

but thats meh

[tender shard]

or just use NMS

[remote swallow]

okay so mojank are fuckin dicks and have 3 sounds to one namespace, how can i guarantee its always the 2nd sound

[eternal oxide]

3 to 1? explain

[carmine mica]

you have to specify the same seed for the sounds

[stray nacelle]

how to send image 💀

[tender shard]

a sound that has 3 different sound files

[mortal hare]

maps

[tender shard]

variants

whatever its called

[gray talon]

is there anyway to send chiptune to the client

used noteblock and its terrible

[onyx fjord]

shitty to maintain

[young knoll]

You would need a resource pack to do anything more fancy than noteblocks

[onyx fjord]

i hate using nms

[gray talon]

making a gameboy emulator

but lacking sound because yes

[tender shard]

ClientboundSoundEntityPacket. the last field is a long, where e.g. 0 should always be the first defined sound, etc

[remote swallow]

packets

pain

[tender shard]

actually all you gotta do is change the version in pom.xml and recompile

[onyx fjord]

i know everyone loves having 10 modules

[remote swallow]

normally packets wouldnt be an issue except this plugin is for 1.18 upwards and has configurable sounds so i would need to have a field for it

so fun

[tender shard]

you can only have one if you stop supporting outdated versions

[young knoll]

Do we not have api for the sound index

[onyx fjord]

but with a library you dont need to give up on older versions

[tender shard]

is there even a protocollib version for 1.20?

also who cares about older versions

[onyx fjord]

yes ofc lmao

[tender shard]

where?

spigot says "1.17 native, tested up to 1.19"

[remote swallow]

why does the uk own this tiny part of land

[young knoll]

Dev build

[eternal oxide]

The Falklands Isles

[onyx fjord]

thats for release

not builds

[tender shard]

where is that from? on github the latest is also 1.19.4

[onyx fjord]

CI

[upper hazel]

Using abstract classes and the "strategy" pattern, I'm trying to find a way to effectively manage textures that distract the player from teleporting in the game. These classes have similar logic, but in some ways they are different. I have created an abstract rtp class and an rtpManager class which contains all the classes that inherit the abstract rtp class. However, one of the rtp variants has its own unique check, and the manager does not know which class it is working with. I need advice on how to solve this efficient problem.

[bitter rune]

It's like asking why does the USA own Hawaii

[tender shard]

took them over a month for 1.20 0o

and it's nowhere to be found "officially", the jenkins also says "latest is 1.19"

[remote swallow]

thats somewhat near them

[onyx fjord]

ci is official

wdym

[tender shard]

i'd just use NMS, it's like one line

[remote swallow]

not down by brazil

[eternal oxide]

The UK occupied 2/3 of the world at one point

[onyx fjord]

that commit was for 1.20.1 not 1.20

[remote swallow]

british empire was great

[onyx fjord]

build for 1.20 is cleared i think

[remote swallow]

can we get it back

[tender shard]

it says "recommended versions 1.19.4" and you only find out that a 1.20 version is available if you manually go through the latest builds until you find the one that has "1.20.1 support" in its changelog

[bitter rune]

And USA has Alaska

[onyx fjord]

that version is recommended for 1.8-1.19.4

i dont see what you dont understand

[tender shard]

so how does one find out that it supports 1.20? by going to the jenmkins page, then manually click on build 661, read it, go back, read build 660, go back, etc, until you find the build that mentions 1.20?

[young knoll]

You could just download the latest one and try it

[bitter rune]

You could probably just Google 1.20.1 protcollib and Google will direct you there

[gray talon]

why even bother to use protocollib

[tender shard]

yeah but why would I even try to download something that mentions both on the jenkins page and on the spigot page that the recommended version does not support latest

[tender shard]

this ^

[gray talon]

just make your own

it took less than 15 minutes

[onyx fjord]

seems like people have no issues finding it

i use packetevents because i can shade it

[gray talon]

spend 30 more minutes and you have a decent library

[onyx fjord]

idc about a megabyte bigger jar

[onyx fjord]

a bit more lol

but you dont even need nms

you can do it purely with netty

[gray talon]

this is just netty

i mean i dont say i use netty whatsoever

at the end a server is just a ping pong machine

[mortal hare]

finally 1.8.8 is being defeated

[young knoll]

1.8 was defeated long ago on bStats

[gray talon]

but the reality is

for classic minigames server

1.8 is no brainer

[young knoll]

Meh

[mortal hare]

https://minestom.net/ looks ideal for minigames

[young knoll]

Just use old PvP in new version

[onyx fjord]

i wonder how much time it takes to develop a working stable server on it

[gray talon]

most people doesnt gone through that much effort

minestom is not plugnplay

if there is one then most of the functionalites are missing

and exploit vary from one to another implementation

[grim ice]

It's quite obvious that time is not with 1.8.8's side lol. but it's still the most famous version pre-1.19

[gray talon]

and 1.13+ scaling is absolute horrible

most performant server still relies on 1.8 or even a heavily modified version of 1.7 (hypixel)

[young knoll]

You know you can just

Remove the stuff you don’t use from modern versions

[gray talon]

sound easier said than done

you remove one and another one breaks

[gray talon]

so whats the point of continue using it

budget gamers still play on 1.12-

[young knoll]

Good for them

[gray talon]

1.12 imo is the best non 1.8 version

[tender shard]

the best non 1.8 version is 1.20.1

[grim ice]

I personally dislike 1.8 pvp and 1.20 crystal pvp

[young knoll]

You can just remove crystal PvP

[tender shard]

what even is crystal pvp lol

[grim ice]

1.8 pvp is legit just buying a good mouse and developing Arthritis

[tender shard]

or a macro

[young knoll]

End crystals do a lot of damage

[river oracle]

Nah it's 1.19.4 because registry api hasn't been merged yet

[kind hatch]

It's where you place down an obsidan block, and end crystal on top of it and then break it.
All within the span of .5 seconds.

[grim ice]

1.20 crystal pvp is disgusting, simply put, you most definitely are obese or stinking, or a child molester if not all of the above if youre main goal in life is 1.20 crystal pvp

[gray talon]

hypixel uses 1.7.2 and never left for a reason

[young knoll]

1.7.10

[gray talon]

because newer version is a bloat

[river oracle]

Yeah

[gray talon]

BIG bloat

[young knoll]

And that reason is they have too many patches to update

[river oracle]

It's impossible to fucking upgrade a monolithic system

[grim ice]

No

[young knoll]

They would have no trouble removing any bloat

[grim ice]

hypixel is planning to move to 1.20

sometime in 2024

[river oracle]

They patched so fucking much upgrading is impossible

[gray talon]

LMAO

they DONT

they just add support for it

[grim ice]

💀 if thats what u wanna hear

[tender shard]

imagine playing an 8 year old version that's missing all the new features

[young knoll]

They have talked about moving skyblock to newer versions

[gray talon]

they can add custom protocol

[young knoll]

But only skyblock

[river oracle]

I love when people point out hypixe like they wanna be on 1.7.2

[grim ice]

Yeah

barely anyone plays anything other than skyblock except bedwars

[gray talon]

you see, the entire minecraft server and client is just a ping pong machine

the server send a packet

[grim ice]

so its basically 50% of the playerbase moving to 1.20

[gray talon]

the client receive it

and see

[young knoll]

Yes that’s how multiplayer games work

[grim ice]

💀

[gray talon]

they add 1.20 support by explicitly disallowing older version

and add packets corresponding to 1.20 client

[grim ice]

the reason hypixel didnt move completely to 1.20 isnt because they love 1.8 lmao

[gray talon]

you cannot merge a huge codebase to a newer version without breaking the entire system

[grim ice]

its because they have already built so much in 1.8

[gray talon]

1.7.10

NOT 1.8

[grim ice]

and its gonna take a long time to move to 1.20

[gray talon]

they never use 1.8

[onyx fjord]

idk why people praise velocity so much

[gray talon]

hypixel IS 1.7

[river oracle]

Im losing braincells

[onyx fjord]

most major servers use bungeecord with not issues

[grim ice]

Same thing, outdated, somehow famous software

[onyx fjord]

wynncraft, hypixel

[ivory sleet]

na bro not true

[gray talon]

proof?

[ivory sleet]

they have migrated over time to newer software

[kind hatch]

Can someone please provide proof as to where someone on the hypixel team said what version they are based on?

[ivory sleet]

ask any of their admins lol

like their smps for instance

[onyx fjord]

hypixel smp is a joke

[ivory sleet]

maybe

[onyx fjord]

instead of paying for rank just buy some cheap hosting

[river oracle]

Hypizel smp iS funny

[onyx fjord]

at least you wont have 100+ ping

[river oracle]

I love it xD it makes 0 sense and that's why it sso good

[ivory sleet]

there is proof in the paper disc iirc

agentk did bring it up at some point

[gray talon]

here

[young knoll]

Difference is you only need to pay once to use hypixel smp

[gray talon]

this is the proof

this is from hypixel discord server

you can search it too

they would do the same thing to support 1.20

disallow older version

and stuff newer stuff in

[ivory sleet]

well thats not what ive heard nor read

[kind hatch]

They day they do that is the day 1.8 finally dies.

[gray talon]

look it up in hypixel discord

cecer used to be a hypixel admin

[grim ice]

hypixel works on 1.8.9

if you think otherwise, youre severely mistaken

[gray talon]

because they protocol hack

[grim ice]

https://support.hypixel.net/hc/en-us/articles/360019634940-How-to-Change-Your-Game-Version-for-Hypixel

They updated to 1.8 long ago

[gray talon]

their base is 1.7, they simply emulates 1.8 features

[grim ice]

The misconception that Hypixel is built on 1.7.10 may have come from the fact that the server was originally released in 2013, when 1.7.10 was the latest version of mc

[gray talon]

im p sure this message is not 8 yearsold

[tender shard]

that doesnt mention at all which version they actually use

[gray talon]

as i said

[kind hatch]

They must go through hell to support the newer versions if they are based off of 1.7.

[gray talon]

look it up on hypixel official discord server

[young knoll]

Not really

[tender shard]

but who cares which version they run anyway? what difference does it make whether they use 1.7.4 or 1.8.8 or 1.12 or whatever lol

[gray talon]

they can do everything at this point

armorstand and custom skull textures dont exist on 1.7

they still managed to add them in and use them frequently

on all minigames across the platform

[river oracle]

As long as it's old it's an argument for 1.8 users and etc it's a bad thing if they ever update those versions will likely die

[gray talon]

if you are a skywars veteran

you will remember once there is a specific NCP 1.7.x bug

that kills you for fall damage on slime blocks

they're a company

merging a 6 figure codebase to a completely different platform without knowing if it will blow up or not is not something a company would do

they never used any standard bukkit API

[young knoll]

That part is false

[gray talon]

keyword "standard"

[young knoll]

Even if they heavily modify the server they do still use the api for some things

[gray talon]

im sure as shit that there're 2 things they have ditched completely: entities and blocks

[upper hazel]

who know russ help pls

[onyx fjord]

russ?

[gray talon]

russian

[warm mica]

ian

[narrow flare]

Hey i've question on Hypixel Server the custom heads are big how did they do it? the heads I put on my armorstands are small

[gray talon]

thats just the armorstand head

try to put your character head near it

it will fit roughly

[kind hatch]

ArmorStands are dead.
Long live Display Entities.

[narrow flare]

What can I do?

[kind hatch]

If you use display entities, you can apply a transformation that scales the block to whatever size you need it to be.
If you use armorstands, you could try ArmorStand#setSmall()

[inner mulch]

    public void onJoin(PlayerJoinEvent event) {
TextDisplay entity = (TextDisplay)       player.getWorld().spawnEntity(player.getLocation(), EntityType.TEXT_DISPLAY);
            entity.setCustomName("Hello, I am a text display!");
            entity.setCustomNameVisible(true);
            entity.addPassenger(player);

        }```
why doesnt the entity apear / entity name apear above the player head?

[chrome beacon]

Why are you mounting the player on your text display

[inner mulch]

oooh

wait let me test the reverse

[chrome beacon]

Also use the spawn method that takes a consumer

And modify the text display there

Right now you're spawning the text display and then changing it's values

instead of setting the values and then spawning it

[inner mulch]

ok, but it still doesnt apear to be in the player

[stray nacelle]

lets listen to rotation and moving packet and send entity moving packet too

[inner mulch]

i have never used packets

[chrome beacon]

No need for packets

[stray nacelle]

don't try it, i write my message for rofl

[fluid river]

jree

fava

[chrome beacon]

Use https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/TextDisplay.html#setText(java.lang.String)

[stray nacelle]

uj

[chrome beacon]

Since it's a text display

[stray nacelle]

what is that

[fluid river]

fr

guy changing name instead of text

[green prism]

Has an API been developed for configurable inventories that allow the addition of predefined actions to Inventory GUI elements through configuration?

[fluid river]

999 apis

[green prism]

wdym

[fluid river]

oh you mean spigot api

[echo basalt]

deluxemenus ?

[green prism]

No, something similar to what you showed me the other day

[echo basalt]

yeah so

What I showed you was my own

[green prism]

I know, don't worry, I was asking if they ever created something similar public lmao

[echo basalt]

uhh no clue

That's why I wrote my own

[fluid river]

then yeah

just google some

i'm sure there are lot's of apis for that exact purpose

[quiet hearth]

ow do I make an ender dragon perch to a specific location?

[green prism]

I just created it actually but I don't like the system I used of Reflections, I think it's too heavy

heaviest class (in my opinion):
https://paste.md-5.net/lugacugode.java

How it works:

@LabAnnotations.Inventory(inventoryName = "example")
public class ExampleMenu extends CustomInventory {

    public ExampleMenu(InventoryHandler inventoryHandler) {
        super(inventoryHandler);
    }

    @LabAnnotations.ClickAction("example_action")
    public void onExampleAction(InventoryClickEvent event) {
        // Define what happens when the player clicks an item with the action "example_action"
        event.getWhoClicked().sendMessage("You clicked an example item!");
    }

}

[echo basalt]

Yeah there's no need for reflections

In my case I just have everything as a "menu element"

And those elements can have click handlers associated to them

There's also a main Menu#click where you pass the event and it gets whatever element was clicked on and runs the click tasks

[green prism]

Hmh, could you please suggest an alternative approach for linking an element to a task based on the configuration? Your input would be appreciated 🙂

Annotations seemed to me the easiest and most intuitive method (unfortunately heavy)

[echo basalt]

getElement("example_action").onClick(event -> {});

lambdas

[inner mulch]

    public void onJoin(PlayerJoinEvent event) {
TextDisplay text = (TextDisplay) player.getWorld().spawnEntity(player.getLocation(), EntityType.TEXT_DISPLAY);
            text.setText("test\n2test\n3test\n4test");
            text.setBillboard(Display.Billboard.CENTER);
        }```

why doesnt the entity apear / entity name apear above the player head?

[green prism]

So "simply" you created an "Element" class that contains all the item stack values and the action value for an element, like this one:

@Data
@Builder
public class Element {

    private Material material;
    private String displayName;
    private List<String> lore;
    private String action;

    // more stuff

    private int amount;
    private int customModelData;

And then on click you check what element was clicked and if it has an action?

[echo basalt]

Ideally element would be an interface

And instead of all of that crazy stuff you just pass an itemstack and a Consumer<InventoryClickEvent>, as well as any placeholders you'd want

[green prism]

The piece I am missing is this:

How do you formulate a Consumer<InventoryClickEvent> from an "action" value given in the config? I'd have an idea but I'd like to know yours as well

[echo basalt]

There's no specific action value in the config, I just link it to the "item name"

When reading the config each item is given a name

Which is the name of the section where the item is defined

So I make an element with that item and put it in a map

[icy beacon]

in ACF, how do i get the previous argument in command completions?

commandManager.commandCompletions.registerAsyncCompletion("culture-level") { context ->
  val previousArgument = ???
  val someValueBasedOnPreviousArgument = ...

  return@registerAsyncCompletion someValueBasedOnPreviousArgument
}

[green prism]

So in addition to the char, you also use another String identifier

right?

[echo basalt]

The char is the identifier

[green prism]

Oh, WOW! That's great!

[echo basalt]

anyways I forgot how mongo codecs work

ah it's in the client settings

[tender shard]

getContextValue(Class, Integer)

[icy beacon]

integer represents what?

[green prism]

Then you simply split any string in the List<String> by spaces, right?

To find elements

[echo basalt]

uhh

it's a bit convoluted

[tender shard]

if your command has a signature CommandSender, String, String, String
then int 1 (or 0?) is the first string, 2( or 1?) is the next one, etc

[icy beacon]

ty, i'll test it now

[echo basalt]

but you can do it without spaces as long as the string is 9 characters long

and split it by each character

so I do have checks and support both

It's some icky code

but it works

[quaint mantle]

I can't find org.bukkit.OfflinePlayer.getLastSeen() in the docs

what does it return?

[echo basalt]

paper method maybe

[quaint mantle]

any examples?

[echo basalt]

yeah it's paper

probably an epoch

[tender shard]

because it doesnt exist

[green prism]

Thank you very much for your advices 😄

[echo basalt]

¯_(ツ)_/¯

[fluid river]

imlusion gives free bukkit lessons fr

[icy beacon]

it was 1 for the 1st arg 🙂

[quaint mantle]

OfflinePlayer offlinePlayer = getServer().getOfflinePlayer(username);
if (!offlinePlayer.hasPlayedBefore()) {
                res.status(404);
                return "Invalid";
}
res.type("application/json");
Map<String, Object> playerData = new HashMap<>();
playerData.put("username", offlinePlayer.getName());
playerData.put("last_seen", offlinePlayer.getLastSeen());
``` hmm im not importing any paper stuff here

[echo basalt]

I hope that's async

[remote swallow]

because its added to the bukkit class

they patch it

[echo basalt]

I wrote a minigame guide last afternoon

[remote swallow]

just because you dont import anything paper doesnt mean you dont use anything paper

[icy beacon]

this is 1.19.4 and it's indeed paper

albeit being in bukkit class

[tender shard]

well if you have paper-api in your pom or build.gradle, then you are importing paper stuff

[quaint mantle]

hmm alright

[fluid river]

you were literally explaining it for an hour in vc yesterday

[native gale]

Is there a way to run something as soon as server shuts down, but while all plugins are still enabled?

[fluid river]

onDisable()

tho not all plugins

but some of them

ig

[tender shard]

what are you trying to do?

[fluid river]

insert malware

😉

[wet breach]

why would you want this?

[icy beacon]

optic is at your doorstep

[tender shard]

why don't you insert the malware during startup

that's how I always do it

[wet breach]

if whatever you decide to run, takes too long the server will force shutdown

[native gale]

I noticed some weird behaviour on restarts, if people are logged in while server shuts down, some plugin data isn't stored correctly. I want to forcefully kick everyone right before plugins start to disable themselves, so the data isn't corrupted

[flint coyote]

Just ask Carlos to insert the malware

[fluid river]

?

[icy beacon]

maybe you should try to find the cause of that instead?

[fluid river]

fbi, open up

[wet breach]

sounds like a design problem

[fluid river]

fr

[native gale]

I mean, I can't debug every plugin out there, it would be easier to handle it on my side

[echo basalt]

someone's not joining their futures onDisable

[flint coyote]

That's an issue in those plugins, tell the authors about it

[icy beacon]

but you kinda should, if some plugin is faulty you should find out which one is

[wet breach]

the problem is more then likely instead of saving data when the server is stopping, they are saving data only at predefined times instead

[fluid river]

optic is cool

[native gale]

Okay, if I ever figure out why, I will, but I have the problem right now and they will implement the fix who knows when

[icy beacon]

then replace the plugin

[flint coyote]

If I were to be reported such an issue I'd fix that within 1-2 days

[icy beacon]

if a plugin is faulty why use it?

you want a high quality server, not a hackishly built one, i reckon?

?ask

[undone axle]

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

[native gale]

You? Maybe. Not you? Who knows. The issue isn't critical, I've seen some plugin authors not fixing critical issues for years

[flint coyote]

Are we talkin about some niche plugins?

[native gale]

I don't know yet which plugin causes the problem

[icy beacon]

find out

[wet breach]

this is why I don't run plugins I don't control

[flint coyote]

So you know the data isn't stored and that causes issues but you don't know which data?

[icy beacon]

remove half of them, then if it didn't help, remove the other half, etc

[icy beacon]

^^ except for stuff like papi/protocollib/etc

[wet breach]

I don't use any of that stuff

[native gale]

Oh come on

[flint coyote]

frostalf with his own WE and WG

[icy beacon]

even better haha

[wet breach]

I have a variation of WE and WG

[native gale]

Okay, the question was "how to run something before plugins start to disable themselves" and the solution you propose is to "debug every plugin I use"

I don't care right now, I want to implement a quick fix

[wet breach]

typically you do it in the onDisable() but as I said, you can't totally rely on it if it takes too long

but its strange you know data is missing, just don't know who owns that data

[flint coyote]

Even in the onDisable() his plugin is not guaranteed to be unloaded first

[wet breach]

correct, they are unloaded in the order they are loaded usually

if all you need to do is kick players before shutdown, then why not make a plugin that does this then

it doesn't need to happen during the shutdown

[native gale]

That's exactly what I try to do

[wet breach]

just kick all players, and set whitelist temporary

then you are free to shutdown

I typically have scripts that handle my shutdowns, but there isn't really a command you could do and get its output easily from script

so at minimum, just make a plugin that has a command to kick all players

and then you can run that command from script and then the shutdown

but as I said earlier your issue is one of the reasons I have all custom plugins. Very rarely do I run a plugin that isn't under my control

[flint coyote]

I mean you can always run a fork but remaking everything is definitly a long and tedious process

[hallow jackal]

Is there any chance of Player.getLocation().getWorld() returning null? IntelliJ says it may produce NullPointerException but i'm guessing that would only happen if, for example, I were to do something like (new Location(null, 0, 0, 0)).getWorld(). Is this correct?

[flint coyote]

Yes, a players Location will always have a world

All IntelliJ does is listen to the @Nullable annotation

[hallow jackal]

Awesome, thank you!

[wet breach]

I don't run forks because its not like I will be able to pull changes from upstream without issues. Its far better to make your own because it will contain the features you need not stuff you don't need

as well as if there is any issues you can update it at will

not all plugins are open source either

[echo basalt]

There are some plugins that are huge lifesavers but there is also a lot of filth that needs a proper rewrite

There's no need to reinvent the wheel but you should always engineer your own solutions if the current ones available are below your standards

[wet breach]

because I run custom plugins, its not like I have a million of them and usually end up having overall less plugins needing to be loaded

and they work together more seamlessly instead of some cobbled together system XD

[wet breach]

while true, I don't use software or code outside of my control

I don't use anything where I have to wait for some outside entity to fix and then even if I could fix it, it creates issues when it comes time they decide to update

since the solution is a fork of those that are open source I may as well just make my own

only way to get value from mysql with java is sql codes ?
is there any other way?

[onyx fjord]

huh

you mean sql statements?

[quaint mantle]

i mean

[remote swallow]

you want to get sql out of mysql, without sql

[quaint mantle]

i tried to use mongodb

and mongodb has custom api

[remote swallow]

correct

[quaint mantle]

so i can do that

[onyx fjord]

oh you want something like that for sql?

[quaint mantle]

db.getvaule("money")

[onyx fjord]

thats called an ORM

[quaint mantle]

but mysql works only sql codes

[onyx fjord]

google java ORM

[quaint mantle]

i mean i create custom objects at mysql

[onyx fjord]

its a type of library that makes working with SQL easier in object oriented languages

[quaint mantle]

but depends mysql ?

idk

wait

i will explain this

you either use iterator.remove() while iterating a loop

[timid hedge]

Sorry i dont understand what you mean

[mortal hare]

or you're running code in multiple threads which is not threadsafe

[charred blaze]

i was running an async task

[remote swallow]

you are missing a bracket

thats what you need

you have 1 missing

[charred blaze]

ProxyServer.getInstance().getScheduler().runAsync(plugin, task);

like this

[undone spindle]

👀help

[mortal hare]

what's inside of that task?

give us some code

[remote swallow]

just add another bracket before the .start

[charred blaze]

it fails on plugin.saveConfigIntoData();

which is method i screenshoted above

[mortal hare]

i believe underlying implementation of snakeyaml that bukkit configuration api uses is not threadsafe

afaik

so just i cant use asnyc?

[undone spindle]

hey i was wondering if someone could help me with what this error is.

[charred blaze]

uh ok

[mortal hare]

im not sure if it would work but try wrapping plugin.saveConfigIntoData() inside

synchronized {}
``` block

[charred blaze]

hm

ill try to

but

i dont have many opportunities to test the code

is there anyone who can confirm that will work

[remote swallow]

?paste the method

[undone axle]

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

[charred blaze]

btw today we received some sort of bot attack

maybe errors were printed when attack was ongoing

[mortal hare]

i would say dont touch the async part if you dont know what youre doing

[charred blaze]

and that caused some thread things

[mortal hare]

it would lead to fatal corruption

of the data

if you dont handle it properly

[charred blaze]

ok ill not use async

i dont think its necessary when saving config

[remote swallow]

just the method

saving config in async should be fine unless saving it from multiple threads

do you call save() method inside main thread?

[fathom basalt]

I am implementing a plugin that wants to use the API of the EssentialsX plugin but not fail if EssentialsX is missing. At the moment I'm getting a NoClassDefFoundError because the Essentials class is not on the classpath. Are there examples of how this can be done gracefully?

[mortal hare]

or just in this runnable?

[charred blaze]

how can i check

[remote swallow]

add depend: Essentials to plugin.yml

[mortal hare]

do you call saveDataInConfig() outside of the runnable?

[grim ice]

https://github.com/xxDark/SSVM whats the point of this again

[eternal oxide]

^ will prevent yrou plugin loading if no Essentials

[charred blaze]

in the same event listener? no

[mortal hare]

anywhere

not in the listener also

[charred blaze]

yeah i use it in some command classes

[remote swallow]

    private void activitySwitcher() {
        (new Thread(() -> {
            scheduler.scheduleWithFixedDelay(new Runnable() {
                int previousIndex = 0;

                @Override
                public void run() {
                    Random random = new Random();
                    int index = 0;

                    while ((index = random.nextInt(activities.length - 1)) == previousIndex) {
                        System.out.println(index);
                    }

                    shardManager.setActivity(activities[index]);
                    previousIndex = index;
                }
            }, 0, 10, TimeUnit.SECONDS);
        }.start()
        );
    }

[mortal hare]

jvm inside jvm

wtf

[charred blaze]

is it problem?

[mortal hare]

its probably can you try to execute the command and somehow invoke that listener

it should throw ConcurrentModification exception

probably

[charred blaze]

and if it does then what

[mortal hare]

you know where's the problem

[charred blaze]

and?

how can we fix it

i mean

error is already there

in logs

[mortal hare]

the runnable that you're calling is on the separate thread from the main thread, and if you're using the same configuration object inside the main thread and the separate thread you need to synchronize the method you need do synchronization

try adding the synchronized keyword on saveConfigIntoData()

[charred blaze]

uhhh

[mortal hare]

public void synchronized saveConfigIntoData()

[charred blaze]

this is getting very far

ah

[remote swallow]

it worked for me

[mortal hare]

that way if you calling this method from separate thread, another thread will wait till it executes

[icy beacon]

i think context is lacking

[charred blaze]

can i just remove async from the code? i dont think saving config will impact that much server's performance

[icy beacon]

maybe you missed a bracket before or after this function

[remote swallow]

oh i did miss one ```java
private void activitySwitcher() {
(new Thread(() -> {
scheduler.scheduleWithFixedDelay(new Runnable() {
int previousIndex = 0;

            @Override
            public void run() {
                Random random = new Random();
                int index = 0;

                while ((index = random.nextInt(activities.length - 1)) == previousIndex) {
                    System.out.println(index);
                }

                shardManager.setActivity(activities[index]);
                previousIndex = index;
            }
        }, 0, 10, TimeUnit.SECONDS);
    }.start()
    ));
}

[mortal hare]

you can, but if you have hard drive with big latency or you're saving lots of data, it could take a hit

usually hard drives are kinda slow to save data

so you can have some spikes

but it depends actually

new error while installing https://paste.md-5.net/qufuvadepe.sql

[charred blaze]

error was literally spamming btw

alots of time

[mortal hare]

try adding synchronized as i already said

or remove async

[charred blaze]

ok.

[mortal hare]

from runnable

[charred blaze]

so like this?

[mortal hare]

yes

[charred blaze]

ok thanks

[mortal hare]

try it and see if that solves it

[charred blaze]

will try it tomorrow. cant restart rn

[mortal hare]

im not really good at multihreading stuff but im quite sure i know what's going on but without much of a code i cant do much so

if error persists you can contact me

tomorrow

but its really not safe to keep this running

on the server

[charred blaze]

im not really sure i understanded correctly. when does error happen exactly? like when player trys to join & some other player tries to execute command at the same time?

[mortal hare]

trust me, you can ruin your data

[grim ice]

maybe?

[mortal hare]

that's my guess

[mortal hare]

since you save config from main thread by executing the command and when joining from the separate thread

data race happens and boom, concurrent modification exception

[remote swallow]

thats something ur end then

[mortal hare]

because two threads try to modify something they couldnt do at the same time

[charred blaze]

yes but error was literally spamming like 2 in a second. i dont think someone was using the command too much

[remote swallow]

why are you even creating a thread just to do stuff in a runnable in the first palce

place

idk, but its multithreading issue, that should be solved ASAP. its critical and can lead to corruption of your data that you're saving instantly.

[charred blaze]

its just friends plugin data

i dont care much about it

[mortal hare]

good to know

[charred blaze]

thanks for trying to help ❤️

i suggest saving things on the database tbh

that way multiple platforms can access your data (web forums can read your game data, etc)

[modest bolt]

I want to create a listener in response to an event, then handle said event

so for example a player hits another player

that triggers an onDamage event, then the main listener creates more listeners to apply the effects

I want to somehow run the onDamage handler for the secondary listeners

how can I do that?

[chrome beacon]

Sounds like you want one listener that does a couple of method calls

[modest bolt]

well yeah, but I don't want to write an interface

as the result would look very similar to the Listener interface that already exists

[eternal night]

you 100% do not want to dynamically register new listerns during the runtime

[modest bolt]

makes sense

[eternal night]

the server has to rebake the entire handlerlist when you register a listener which, doing that every time a onDamage happens is pretty not smart

[modest bolt]

i see

so how can I call the onDamage event of this secondary listener

for context im trying to implement custom enchantments

and on a damage event, ill parse out the item lore of the sword

[remote swallow]

have an interface or an abstract class with a handle method that takes the event as aparam

[icy beacon]

bungeecord question: is there any way to get the player's uuid in PreLoginEvent? according to the docs, This will NOT contain many attributes relating to the player which are filled in after authentication with Mojang's servers. Examples of attributes which are not available include their UUID.. or can I use another event, that has the player's uuid, to prevent the player from joining?

[modest bolt]

then instantiate the corresponding custom enchantments and run their onDamage events

but ofc it doesn't have to be ondamage

[modest bolt]

i see, that makes sense, thank you!

[chrome beacon]

LoginEvent?

[hazy parrot]

How can you prevent them from joining if you don't know who they are. There is Login Event but not sure if it's cancelable, try and see, if it's not you might just want to kick player

[chrome beacon]

Login Event is cancellable

[hazy parrot]

Cool then, just cancel it

[icy beacon]

are you sure that it's just cancelling? for example, in bukkit for AsyncPlayerPreLoginEvent you can do Event#disallow

and also there does not seem to be an uuid in LoginEvent

Get UUID from the connection

[narrow flare]

I have a question about hypixel the box is a customHead on an armorstand?
I made a custom head on an armorstand and it is smaller than the hypixel custom head why?

[icy beacon]

that was my initial thought too, but there's also PendingConnection in PreLoginEvent, which does not supply an UUID, which means that PendingConnection's UUID is something else

am i wrong?

i just started with bungee lol

[chrome beacon]

The connection uuid can be empty

[icy beacon]

ohh, that makes sense

alright, thanks!

[chrome beacon]

Small armor stand?

[eternal oxide]

You can get the UUID from the connection in Bungee LoginEvent.
You register an intent in the LoginEvent, get all your processing doen, including db access, then set the cancel state and reason (if banned) then completeIntent

https://ci.md-5.net/job/BungeeCord/ws/api/target/apidocs/net/md_5/bungee/api/event/AsyncEvent.html#registerIntent(net.md_5.bungee.api.plugin.Plugin)

it forces the LoginEvent to wait (async) until you completeIntent

[icy beacon]

so in between registration and completion i can get the uuid from pendingconnection?

[eternal oxide]

if you don't need to do any db access you don;t need to register an intent

[icy beacon]

i do

[eternal oxide]

intent is to make it wait

alright, cool

then register an intent and pass the event off to whatever code you need to run

[icy beacon]

event.registerIntent(plugin)

// :snip:

event.completeIntent(plugin)

correct?

[eternal oxide]

The Event will not continue until all intents are completed

[icy beacon]

ok maybe i'm a bit confused, how exactly do i execute my code after registering an intent then?

[eternal oxide]

you can do it in the event, or pass the event off to a future

[icy beacon]

so would this code be valid?

[eternal oxide]

so long as you tidy up when your code finishes or your future returns

yes

[remote swallow]

its a bug someone else had and most likely wont be fixed

alright then, thx! i'll wrap it into a future

its already async so you probably don;t need to use a future
