Enable the mock first

[clever lantern]

how

[grim hound]

how do I allow aternos users to install my plugin?

[shadow night]

you gotta submit it to their system and they will have to either accept or decline it

[grim hound]

where can I send it?

[shadow night]

last time I saw that feature, you had to make a server, select bukkit or paper as your server software, navigate to the "Plugins" section and there somewhere there is a button "Can't find a plugin?" or something like that

[quaint mantle]

Enable the mock first

[grim hound]

for it to be added I think I need 1k downloads

[shadow night]

well, oof

what's your plugin?

[grim hound]

https://www.spigotmc.org/resources/alixsystem.109144/

[grim hound]

an antibot and login/register

[shadow night]

wow that's crazy

[grim hound]

is this sarcastic?

[shadow night]

no

it's insane

very cool plugin

[grim hound]

appreciate it man

[quaint mantle]

Cool plugin

[shadow night]

I shall put this to the test when time's sweet embrace permits.

[grim hound]

Poetry.

anyway, I'll add a bot attack detection algorithm today, since I had some issues with the AsyncPreLoginEvent

[shadow night]

oh

well, nice

[grim hound]

how will you test it, if I may ask?

[shadow night]

just put it onto some testing server, join, check configs, maybe invite a few friends

[onyx fjord]

i do i was afk at the time

[umbral ridge]

lies

xDD

[onyx fjord]

?

[remote swallow]

thought so but he got me to fix it

you missed the fact of enchantment storage meta and you always set the cap instead of only setting when its higher

[onyx fjord]

im p sure i fixed that like 2+ hours ago

[remote swallow]

kekw

[remote swallow]

outdated moment

[onyx fjord]

something looks off visually tho

table shows 3 and i get 2

oh

[remote swallow]

gotta change it in the prepare event too

[quaint mantle]

Increaste the cap

[onyx fjord]

table has its own logic

yea

[quaint mantle]

Change cap to 100

No one likes enchant cap

[onyx fjord]

its configurable

but not above vanilla

[quaint mantle]

Imagine player having netherite axe with sharpness 100 and with strength potions

[quaint mantle]

I did the maths and it would require 1.000.000 sharpness 1 books to reach that

884.736 Sharpness 5 books

[shadow night]

lol

[grim hound]

why does AsyncPreLoginEvent return ALLOWED even if the player's join is disallowed because of a ban?

[eternal oxide]

preLogin is before teh actual login so no ban has been checked yet

[patent horizon]

would anyone know why i can't inherit the ItemBuilder class? nothing inside of it is final, so im not sure where this error is coming from

[slender elbow]

in kotlin classes are final by default, you need to mark it as open (open for extension)

[patent horizon]

ah ok tyvm

does everything within it need to be open, or just the class itself?

the error doesnt go away but i can't tell if it's just an ide thing

[quaint mantle]

Bytecode optimization

[dry hazel]

only the class needs to be open for it to be capable of extension

[patent horizon]

ah looks like an ide problem, restarting fixed the error

[peak depot]

can I change the default unknown command message with bungeecord so I dont have to put a plugin on every single sub server?

[umbral ridge]

hey, there can't be multiple players with the same name on the server right? Eg. Player1, playER1, plAYeR1

[peak depot]

maby could work on cracked but I dont think it would work on online servers

[quiet ice]

Well, the UUID is the only really unique aspect of a player

I would not rely on the name being unique

Especially given that there are actually duplicate usernames out there, albeit being very rare

[umbral ridge]

yes, so that would work? if I joined with Player1 and then playER1 would also be able to join?

I'll change my algorithm a bit to parse the parameter as a player and then compare their uuid

[quiet ice]

If you just want to select players from the arguments of a command, use bukkit's selector API

for everything else: what are you doing?

[umbral ridge]

I've got a /teleport <player> command, and im checking if the command executor isn't the same as parameter name (args[0] takes in a player name)

So I should still check the UUID for that?

[quiet ice]

Yes

[umbral ridge]

alright

does Bukkit.getPlayerExact() throw an exception if player isnt found?

[quiet ice]

And use https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Bukkit.html#selectEntities(org.bukkit.command.CommandSender,java.lang.String) to select your player

[umbral ridge]

thanks, with that I should still pass in the UUID? xD

[quiet ice]

You will still need to check whether the player has selected itself, but that is just a simpe if (sender != entity)

[umbral ridge]

how about this

[quiet ice]

You might also be able to do targetPlayer == player to upset quite a few people out there

targetPlayer.equals(player) is the best approach tho

[ivory sleet]

I’d assume just returns null

[umbral ridge]

thank you

works

making a teleport command is rather complicated

have to handle everything, what ifs

(teleport command with delay countdown)

[ivory sleet]

Yeah, even the simplest of things become complicated when you do it properly at times

[umbral ridge]

yes exactly xD

So how do you send a clickable message to the chat?

[ivory sleet]

Player.Spigot::sendMessage

[deep herald]

can someone help me check if a player is in a map from a spigot server?

im doing the map in bungee

[young knoll]

?pmc

[undone axle]

https://www.spigotmc.org/wiki/bukkit-bungee-plugin-messaging-channel/

[deep herald]

i wanna do bungee bukkit

might just use redis

[warm mica]

Redis is more effort to set up and more resource hungry for simpler projects. Bungee messaging however requires a player to be online, and there is no 100% promise that your message will be delivered, as with e.g. the player leaving

[deep herald]

this isnt a simple project

[warm mica]

Well, then redis is possibly better suited. You also have the benefit of being able to deal with the data on a separate thread, instead of the main thread, as with bungee messaging

[ivory sleet]

Its fine, i mean u can just grab a nice redis container and get it all setup for u in principle

[warm mica]

that is if you are using containers in the first place and know what you are doing. and it's already more than doing nothing :p

[ivory sleet]

Yea, tho for anything manageable at a larger scale docker and kubernetes becomes almost an implied standard

[quaint mantle]

public class CustomItemManager {

    private final Plugin plugin;
    private final Map<String, CustomItemListener> listenerMap;
    private final Map<String, ItemStack> itemStackMap;

    public CustomItemManager(Plugin plugin) {
        this.plugin = plugin;
        this.listenerMap = new HashMap<>();
        this.itemStackMap = new HashMap<>();
    }

}```

for these two hashmaps, should I find a way to combine them?

[ivory sleet]

Not necessarily needed

[quaint mantle]

they will both have the same keys

[ivory sleet]

Then maybe yea

[quaint mantle]

maybe I can combine them in like a CustomItemProvider?

[lost matrix]

Docker. Sure. Kubernetes. Overkill unless you need to really scale.

[ivory sleet]

Well its not always to make it scale

Sometimes its just easier to manage and is convenient if you learnt it

Ofc if you’ve no interest in expanding your knowledge then yeah prob not sth u wna touch

[lost matrix]

What else would you need orchestration for, if not horizontal scaling? 🤔

[lost matrix]

Yeah this looks like you should create a new class for both.
What is the purpose of the ItemStack?

[ivory sleet]

I mean sometimes you do it to automate installations and just if someone got a good setup of a service you can yoink it

[quaint mantle]

so ive been in a little bit of a designing battle

[ivory sleet]

But scaling is a key factor obviously

[quaint mantle]

and it's basically the CustomItem

and then there's the implementation for the customitem which is the CustomItemListener

[ivory sleet]

Max you could presumably bundle the two maps with some sort of record class

Or well their value objects

[quaint mantle]

hm

[ivory sleet]

Record(Listener, Item)

[quaint mantle]

no ik

[ivory sleet]

:>

[quaint mantle]

but then i gotta store the listener in a variable

wait

[young knoll]

Pair<L, R>

[quaint mantle]

record does that

[young knoll]

👀

[lost matrix]

[ivory sleet]

Map.Entry<K,V> :3

[quaint mantle]

oh wait

I can just make it private right

like a private class in the manager

[ivory sleet]

yea

[quaint mantle]

doesn't hashmap do that

it has like a node class

[lost matrix]

I kinda dont like where this is going

[ivory sleet]

yes max

[quaint mantle]

wdym

[ivory sleet]

HashMap code is kinda old tho

Not a primary example to take inspiration from

[lost matrix]

Packing non-data classes into a record just screams design issue to me.
Same goes for listeners in a map.

[echo basalt]

Or maps in a listener

which is a lot more common

[quaint mantle]

ok

well i dont have to use a record

but it's anyways gonna be private

[lost matrix]

Yeah but that is just because ppl dont know "how to pass a value from one class to another"
And if they get it, they start passing around maps and come to us with impossibly convoluted exceptions
because everything is everywhere at all times.

[ivory sleet]

Yeah, tho in this case a record would just act as a bundle/context object

[echo basalt]

I worked on a custom item api today

Just to mess around and see if I could actually learn something

[quaint mantle]

can i see how u did ur system

[echo basalt]

sure I could replace onClick with an event bus thing

[quaint mantle]

how im doing my thing is

u register it to a manager

[echo basalt]

But I just took inspiration from nms

[quaint mantle]

like

[echo basalt]

The manager is still a thing

[quaint mantle]

ok wait hold on

i dont think ima pass an itemstack at all

[ivory sleet]

sounds like a good choice

[lost matrix]

I would have a few notes on this but i should def go to sleep 🙂
But using the PDC to map functionality to items is my approach as well.

[echo basalt]

I still have an abstraction layer on top that grabs the itemstack from the config based on the identifier and passes it on

[echo basalt]

I accept feedback

[quaint mantle]

CustomItemManager#register(String referenceName, CustomItemConfig, CustomItemListener)

[echo basalt]

I'll be travelling in like 6 hours so eh

I should sleep too

[quaint mantle]

is this good

[minor junco]

when was PDC introduced btw?

[quaint mantle]

then to get custom items

[echo basalt]

1.14

iirc

might be 1.13

[quaint mantle]

the only thing which

idk if it's a bad or good idea

is that the configs will be references

[ivory sleet]

wym by that lol

[quaint mantle]

they're all mutable and you can edit them runtime

[ivory sleet]

what is mutable?

[quaint mantle]

the configs

[ivory sleet]

The config data? Or the references to the configs themselves

[echo basalt]

TBh I've never seen the point in modifying and saving configs

[quaint mantle]

both

[echo basalt]

they should be read-only imo

[quaint mantle]

so like

[ivory sleet]

This so much

[ivory sleet]

yeaa go to sleep, gn sleep well :)

[echo basalt]

So like sure you can still have config values

[quaint mantle]

public abstract class CustomItemConfig {

    protected Material material;
    protected String name;
    protected List<String> lore;
    protected boolean unbreakable;

[echo basalt]

That should just be an item builder

and instead of holding all the same fields you just hold meta and modify it

[quaint mantle]

?

oh this is a base for a custom item

[echo basalt]

looks like an item builder to me

[minor junco]

yes but it's very similiar to an item builder no?

[quaint mantle]

things can extend it and have their own values like "int specialDamagePercentage"

[ivory sleet]

Max have you by any chance read the items of effective java?

[quaint mantle]

ive scimmed over it

[echo basalt]

I've only read like 25% of effective java and I've actually adjusted my code style around it a bit

Stuff like static .of methods

[ivory sleet]

A lot of the design points illusion, I and smile point out sorta derive from effective java more or less

Now not everything but a lot of stuff

[echo basalt]

thing is it's like 600 pages

[ivory sleet]

w

[echo basalt]

I'm ~150 in

[quaint mantle]

does this make sense tho or nah

[ivory sleet]

Haha yea, well u can find githubs with summaries

[echo basalt]

i just found the pdf on github

[ivory sleet]

I dont like state inheritance

[echo basalt]

max can you read this real quick

[quaint mantle]

i have it on my phone lol

[ivory sleet]

but if u rly want it, sure that does work

[opal juniper]

real quick

[echo basalt]

Imma be at my grandma's house tomorrow

[quaint mantle]

christmas?

[echo basalt]

am debating if I should code on my laptop or use it to read effective java

[echo basalt]

p much

Might just bring my driving school book and take notes

as I have my exam in a couple weeks

[quaint mantle]

what course

[echo basalt]

it's literally just driving a car

[quaint mantle]

oh

lol

[echo basalt]

I have some hours on the road, need to do this exam so I can sign up for more

[quaint mantle]

what country are you in

wtf

[echo basalt]

Portugal :)

[quaint mantle]

in us you can get your liscense at 16

[echo basalt]

well I'm 18

[minor junco]

yo is there an event for when a player "leaves" a spectator target, as in when they shift out (without actually listening to the shift entity action)

[echo basalt]

well no

scheduler time

[minor junco]

great

[echo basalt]

But yeah I need to do this entire safety course so I can drive

[quaint mantle]

ok maybe i will make the fields final lol

[echo basalt]

and I can sign up to 16 hours of driving before having to do an exam

Once I do the exam I need to do the remaining hours

Once I hit 32 hours I can sign up for a practical exam where I drive around

[ivory sleet]

The fork that shall not be named does have some events for that

well fyi :>

[quaint mantle]

is driving in ur place hard

[echo basalt]

I've got about 7-8 hours right now, my instructor's schedule is completely packed

[quaint mantle]

in the US it's a lot easier

[echo basalt]

It's hilly

narrow roads

[minor junco]

alright :3

[quaint mantle]

yeah in the US it's super easy

[echo basalt]

Went on the highway in my last lesson and nearly crashed because mfs didn't let me merge lanes

[quaint mantle]

there's really nothing hard about driving here lol

maybe unless you're city driving

[echo basalt]

here's the other thing

it's a manual car

[quaint mantle]

lol

gl

lmao

[echo basalt]

noob

not that hard you just need to prevent it from dying

[quaint mantle]

So here is an export of my Mongo collection (kitData)
https://paste.md-5.net/iyeqimotek.json

I am having trouble after converting from using Bukkit YML configuration to store data, to MongoDB

So far i've spent 6 hours trying to make it work for Mongo (it works on saving this data, and renaming the kit tag, and removing the kit, even loading the kit works) The whole issue here is that when i call my #setUpKitEditorInv method that it won't refresh/update the inventory with the respected column of buttons.

It's very simple, when you save a kit a column of buttons (loadKit, renameKit, removeKit) buttons will be added below the saveKit button.

KitManager class methods:
https://paste.md-5.net/gevebitaha.coffeescript

KitListener (so you can understand how this is being used):
https://paste.md-5.net/jametakowo.java

MenuUtils (where i control the inventory and want to update/refresh) #setUpKitEditorInv is called in KitListener
https://paste.md-5.net/cotizogeze.java

Please help me, i don't know why this is giving me trouble, i've tried literally everything and I think it's about damn time i ask for some help on this

[fair crest]

hey

how do i check a item display name

for a gui

[echo basalt]

Well, you don't

?pdc

[undone axle]

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

[quaint mantle]

if(ItemStack.hasItemMeta && itemstack.getItemMeta().getDisplayName

[echo basalt]

The main thing I'm noticing is that all your code is quite coupled and hard to expand

Which in turn becomes hard to debug

[quaint mantle]

Hmm, could you throw me any tips peer to peer?
How can i make it better to understand?

Im so frustrated i just want the MenuUtils to work correctly

[fair crest]

Umm how do i make the variables for this.

im still new to this. not 100% sure on how to make variables

[quaint mantle]

ItemStack item = new ItemStack(Material.YOUR_MAT);

[fair crest]

oh wait

[echo basalt]

For your GUI you should follow a structure like this
https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

I'd also go over the main problem areas and refactor them following this guide

Split your database logic up and return completablefutures for stuff

[fair crest]

alr so. i have that for a crossbow. but the bug is whenever i click one. it duplicates

[echo basalt]

For your database, I'd make a KitLoadout object

It can just wrap all the params on the other methods but it helps to make the logic a bit simpler

[civic apex]

how can i detect when a player sends a bungeecord command? Like any bungee command, but not any spigot command/chat message

[echo basalt]

And then you can do something like

public interface KitsStorage {

  KitLoadout getLoadoutSync(UUID playerId, String loadoutId);
  void saveLoadoutSync(UUID playerId, String loadoutId, KitLoadout loadout); // display name would be on the loadout object

  default CompletableFuture<KitLoadout> getLoadoutAsync(UUID playerId, String loadoutId) { // You should override this and make sure the futures finish running on shutdown
    return CompletableFuture.supplyAsync(() -> getLoadoutSync(playerId, loadoutId)); 
  }

  ...
}

@quaint mantle

[quaint mantle]

Sorry was reading the forum, im so overwhelmed. But im sure i'll be okay.

[echo basalt]

Which means you can do stuff like saveLoadoutAsync(...).thenRun(this::updateMenu)

[quaint mantle]

Woow smmart

[quaint mantle]

What class would implement this interface?

[echo basalt]

your mongo

and your yml reader

If you want to migrate you can read all the data from one and save to the other

[quaint mantle]

I dont think ur understanding though, I eliminated the use of YML i am only using Mongo

[echo basalt]

Still it's a decent approach that lets you future-proof your stuff

[quaint mantle]

Do you have time for a call? Im not 9 years old i swear. I just am having a lot of trouble understanding, and i've had it with staring at this code.

[quaint mantle]

u should suggest what luckperms did with theirs

I think it's pretty nice how they handled their data

[echo basalt]

uH it's like 3am so I might be quiet

[quaint mantle]

thats fine, ill add you

[echo basalt]

Give me like 15 mins

[quaint mantle]

Sweet!

interface - StorageImplementation
class - handles async stuff and exceptions with the StorageImplementation

[echo basalt]

Yeah that's basically what we're doing here

[fair crest]

so how do i make a right click event

[quaint mantle]

Added you just ping me when you are ready

[quaint mantle]

Listen to InventoryClickEvent and e.isRightClick() i think

@EventHandler
public void InventoryClick(InventoryClickEvent e){

}

[fair crest]

alr

[quaint mantle]

their u go that should help

[fair crest]

can i change e to FireClick?

[quaint mantle]

lol if you wanted to but its just a variable so it doesnt matter

[echo basalt]

give full names to your variables

it's in the good habits list

[quaint mantle]

Yeah i should, but i know e represents events in my code.

[echo basalt]

I mean yeah but do other people know that

[fair crest]

yea im going to see if i can make a basic gun plugin

[quaint mantle]

Great point

[quaint mantle]

I believe in you

[echo basalt]

waiting for your ahh to join the call

discord about to disconnect me at any second now

[quaint mantle]

Well u said 15 minutes, pardon self. Joing now

[fair crest]

thanks, 2 things.
How do i cancel a crossbow shooting a arrow
and how do i make the particles shoot/damage

[quaint mantle]

does anyone know why i can do if() thing; while() thing; but not catch() thing;

[fair crest]

or create particles that do that i guess.

[quaint mantle]

and the same with the else keyword

[wet breach]

catch is for try statements. The correct thing is an else statement

[quaint mantle]

?

no i mean like the syntax

like

[wet breach]

for while statements instead of else its do

[quaint mantle]

if (true) doSomething();
else doSomethingElse();

while (true) doSomethingForever();

try
  throwAnException();
catch (Exception e)
  handleException(e);

@wet breach this is what I mean

[fair crest]

yo guys

how do i cancel the crossbow shooting a arrow

[quaint mantle]

event.setCancelled(true)

[fair crest]

also which button makes the crossbow shoot

[quaint mantle]

I'm assuming you're new so you should learn how to find the event and register it yourself

[wet breach]

the reason it works is because if is a statement and else is just another fancy way of doing if but allowing the if to just jump to a false boolean statement

try catch can only exist inside of a code block

because its purpose is to catch exceptions that arise

[fair crest]

yea im new. im just trying to get a base system of code done for a plugin i want for some friends.

[quaint mantle]

hm

[echo basalt]

@quaint mantle

[quaint mantle]

yo illusion

[quaint mantle]

what do u think of this

[waxen plinth]

eh, try/catch is just terrible

[quaint mantle]

@waxen plinthi am thinking of a new design lmk what u think of it

[waxen plinth]

I think it would be nice if they had better ways to handle nullability and exceptions inline

[quaint mantle]

so i got rid of passing itemstack completly

instead it's something maybe like this

[waxen plinth]

like something to convert it to an Optional, or if you could do a prefix try? to turn something from fallible to nullable

[ivory sleet]

I think switch (x) {
case throws Exception e -> …
}
could B cool

[waxen plinth]

hmm

yeah that would be an improvement

[quaint mantle]

CustomItemManager#register(String referenceName, CustomItemConfig config, CustomItemListener itemImpl)

something maybe like this

[waxen plinth]

it's just so terrible to handle exceptions

verbose

[ivory sleet]

But yeah Optional is also a bit limited, as its not as powerful as rust Option, Haskell Maybes or yk anything else thats properly addressing nullability

[quaint mantle]

idk abt yall but i kinda like handling exceptions

[waxen plinth]

yeah seems reasonable

[waxen plinth]

it's good practice to, but java gives you pretty terrible tools for it

[ivory sleet]

I think its also really hard to choose between null, exception and result objects at times, its not made easy to understand when to use what on a deep level

[quaint mantle]

lol

[waxen plinth]

yeah exactly

[quaint mantle]

imagine java but no runtime exception

[waxen plinth]

it was too late when null was baked into the language

[ivory sleet]

Yeah

Well they want to address null partially with valhalla

Which is a step in the right direction

[quaint mantle]

yk what this reminds me of

[waxen plinth]

god I might need to make a jvm lang

[quaint mantle]

when u get armor of an entity with bukkit it can return null

but if you set the armor of an entity u cant use null

[waxen plinth]

if I could make elude target jvm that'd be sick

[waxen plinth]

yeah there's a lot of inconsistencies like that

[ivory sleet]

Well Max I firmly believe in minimizing the amount of null state, but null can be advantageous to exceptions as they’re way less resource intensive

[quaint mantle]

ok

i wasn't even talking abt nulls

i was just wondering why java had syntax like that lol

[quaint mantle]

what if I wanted to access the config in the impl

maybe I can pass in the manager within each event?

im pretty sure JDA does that

[ivory sleet]

Java goofy

[quaint mantle]

class FileConfigServiceTest {

    @Test
    void testExceptions_loadAndRegister() throws IOException {
        ConfigService<TestConfig> configService = setUpNewConfigService();

        assertDoesNotThrow( () -> configService.loadAndRegister(new ValidConfigWithObjects()) );
        assertDoesNotThrow( () -> configService.loadAndRegister(new ValidConfigWithPrimitives()) );
        assertThrows(IllegalStateException.class, () -> configService.loadAndRegister(new ValidConfigWithObjects()) ); // Loading an existing config.
        assertThrows(IllegalStateException.class, () -> configService.loadAndRegister(new NotValidUnAnnotatedConfig()) );
    }

    @Test
    void testFileContentIsCorrect_loadAndRegister() throws IOException {
        FileConfigService<TestConfig> configService = setUpNewConfigService();
        Gson gson = configService.getGson();
        configService.loadAndRegister(new ValidConfigWithObjects());
        configService.loadAndRegister(new ValidConfigWithPrimitives());
        String contentOfConfigWithObjects = Files.readString(configService.getConfigFolderPath().resolve("ValidConfigWithObjects.json"));
        String contentOfConfigWithPrimitives = Files.readString(configService.getConfigFolderPath().resolve("ValidConfigWithPrimitives.json"));

        assertEquals(new ValidConfigWithObjects(), gson.fromJson(contentOfConfigWithObjects, ValidConfigWithObjects.class));
        assertEquals(new ValidConfigWithPrimitives(), gson.fromJson(contentOfConfigWithPrimitives, ValidConfigWithPrimitives.class));
    }
}

am i doing unit testing correctly

[echo basalt]

no

[ivory sleet]

Your tests are arguably a bit too complicated almost

Or well not complicated

But like

[quaint mantle]

why

doing too much?

[ivory sleet]

You do a ton of shit in ur unit tests

yea

I reckon you could mock some of the logic

With…. mockito ⭐

[quaint mantle]

first one is making sure it's throwing proper exceptions and second one makes sure the saved contents are correct

idk what mocking means

[quaint mantle]

Hey can you please just send me those classes so i can have them as reference?

[river oracle]

can someone explain how Gradients Work/ what they are and what an implementation would look lik

most of the resources I found on line just use AWT which really doesn't explain a lot as its abstracted behind API

[warm mica]

You are simply performing a linear interpolation for each RGB color

[echo basalt]

In short, yes

You can have a gradient going over multiple colors in the spectrum

So you'd need to interpolate between each color for each character

For example, if you have 3 colors, you divide the string up in 3 parts

[quaint mantle]

Bro what time is it for you

[echo basalt]

6:20am

[quaint mantle]

Did you even sleep

[echo basalt]

no

family's travelling in an hour

I'll just down 15 red bulls

[river oracle]

yeah but how do you get the color transition effect

what sort of math is it

[echo basalt]

you just interpolate

lerp all 3 colors

[river oracle]

wtf is an interpolate lol

[echo basalt]

start + (end - start) * progress

[river oracle]

so. do i gotta

change it

[echo basalt]

write some actual code yeah

[fair crest]

it was ment to be.

[fair crest]

wait so how do i check the meta data

facts

[fair crest]

so how would i make it so i can check metadata.

then find the display name and cancel event

im still new to this

[echo basalt]

you don't check metadata

you just check a tag

can you read the actual post

[fair crest]

alr

so i don't have the variables to do that

ummm

[fair crest]

i read the post

[fair crest]

how do i create a tag tho. still new im not 100% sure and the code the guy showed i didn't fully understand

[quaint mantle]

I know that, but I never knew why it is so, do you know why

Like why is it returning a clone and not directly the ItemMeta of the item

[river oracle]

🤷‍♂️ I suppose the rational is you mass commit the changes to NBT, but that doesn't hold for Bukkit Item Stacks

[fair crest]

hey yall, whenever i use this code to give a item. it doesn't show errors but instead everytime it gives you another crossbow when you try to remove one.

this is the code i used
`public class ClickEvent implements Listener {

@EventHandler
public void ClickEvent(InventoryClickEvent e){

    Player player = (Player) e.getWhoClicked();

    if (e.getView().getTitle().equalsIgnoreCase(ChatColor.RED + "Extreme Gun System"))
        e.setCancelled(true);
        if (e.getCurrentItem() == null){
            return;
        }
        else if (e.getCurrentItem().getType().equals(Material.BOW))
            if (e.getView().getTitle().equals(ChatColor.RED + "Extreme Gun System"));
                player.closeInventory();
                ItemStack arrowItemstack = new ItemStack(Material.ARROW, 1);
                ItemStack item = new ItemStack(Material.CROSSBOW);
                ItemMeta itemMeta = item.getItemMeta();
                itemMeta.setDisplayName(ChatColor.WHITE + "M4A1");
                itemMeta.setUnbreakable(true);
                CrossbowMeta meta = (CrossbowMeta) item.getItemMeta();
                meta.addChargedProjectile(arrowItemstack);
                itemMeta.addItemFlags(ItemFlag.HIDE_UNBREAKABLE);
                item.setItemMeta(itemMeta);
                player.getInventory().addItem(item);

Learn if statements oml

this seriously hurts my eyes

[undone axle]

https://www.spigotmc.org/wiki/creating-a-gui-inventory/

[fair crest]

sorry if it does. but it gets the job done. so ima just test and make sure i got a baseline system backbone

[quaint mantle]

Multiple issues:

• This isnt python. your if statements are totally wrong.
• Duplicate if statement: Checking if title is "Extreme Gun System" twice. Also equalsIgnoreCase doesnt need the chatcolor.
  You arent evening removing a bow, so i dont understand why you expect it to be removen

[quaint mantle]

It doesnt get the job done

your if statements make no sense

oh

so.

thats the issues

ima test 1 thing then take ya advice

wanna see if this wokrs

I don't use IJ so can't advise

clear caches and restart?

[orchid trout]

what is start_server.command or start_server.bat

iont get where it is

[shadow night]

It's in your server directory ig

[orchid trout]

in my project folder?

[eternal oxide]

why are you not doing IDE as a local debug server?

[orchid trout]

how

[eternal oxide]

option 3

[orchid trout]

ok

[mellow edge]

I fixed it by just deleting /.m2/org.spigotmc-api and then reinstalling it

[eternal oxide]

I sure hope not

[half arrow]

Can anyone advise on the best way to update countdowns in item lore for example you see it on auction house plugins, the lore updates dynamically every second? I creating runnables feels wrong for this especially if there’s a ton of items

[shadow night]

You could have one runnable looping through all items but that doesn't sound very convinient either

[half arrow]

Yeah sounds messy, trying to find a open source plugin that does it just to get an idea

[vocal cloud]

If you store an item in a list and then add it to an inventory and update it in the list does it update it in the inventory or does add create a copy?

[shadow night]

It should update

From what my java knowledge tells me

[vocal cloud]

I can't remember if it's a copy or a reference

[shadow night]

I can't either, but ig you could just try it or assume

[vocal cloud]

I'd test it but I'm in bed and it's comfy.

[shadow night]

Oh lol

For such cases I have vnc running on my laptop and on a vm too, so I can test things from my phone

[vocal cloud]

I could do that. Idk if they already have the code for an AH they could just test it easily

[dry forum]

im doing stuff with guis and i wanna get players input but anvilguis are limited to how much text you can have in them and chat wouldnt work for bungee, is there anything else?

[shadow night]

book and quill?

[chrome beacon]

You could use chat with bungee if you wanted to

[half arrow]

any ideas?

[chrome beacon]

You'd need a runnable

[chrome beacon]

.

^^ this or just loop the inventory

Some actions do copy the item so it might be worth looping inventory

[quaint mantle]

if the player does not interact with it, it stays, if he does, the one in the list is just a clone.

I learned this the hard way

[chrome beacon]

Does it get cloned if you cancel the event?

[quaint mantle]

that is something that i didnt try out

what i did to fix it is use

?pbd

?pdb

ah

[chrome beacon]

?pdc

[undone axle]

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

[quaint mantle]

?pbc

yes

that

so i used persistentdataholder to give the item a UUID

and then looped trough the inventories to update

[quiet ice]

And that is why you don't embedd someone's webclient in your software.

[umbral ridge]

really?

[eternal oxide]

So long as it keeps workgi

[grave plover]

Hello everyone,
I am searching for a way to let players from every version (maybe every 1.20.* version) connect to a spigot server with a plugin. I think I have to use packets, but I am not sure how... I do not want to rely on any other API than spigot / nms itself for security reasons.

[chrome beacon]

Just use ViaVersion

security through obscurity is just a bad idea

[quiet ice]

I think I have to use packets
That is a ... rather optimistic guess

[grave plover]

There were cases where Spigot MC plugins got compromised...

[chrome beacon]

If you want to do it yourself you'll need to convert every packet yourself

[quiet ice]

Then build from source?

[chrome beacon]

https://wiki.vg/Protocol

^^ Here's the protocol information

Good Luck

[grave plover]

Yep...

[grave plover]

Why every packet?

[quiet ice]

Because every packet has a use somewhere

[grave plover]

I want to understand it myself and not just use a blackbox

[chrome beacon]

You can always read the code yourself

[grave plover]

I thought it might be something like a join packet and a server kick response or smth

[quiet ice]

It's like translating english to french. You need to be able to translate every word, not just "Hello", "Goodbye" and "Food"

[grave plover]

Haa I really have NO overview about it, there are too many classes and I cannot just click through every single of those...

[quiet ice]

So, what if a player wants to break a block? Here too the packets have slightly changed over time. Even if it is just a change in IDs

[chrome beacon]

Writing it yourself won't be much faster

[grave plover]

OH soo you mean the protocols change with every version? that the client cannot recognise older/newer ones? that's a another problem then

[quiet ice]

Yeah?

[grave plover]

I didn't know, then it is out of my matter xd

[grave plover]

I thought there would be similiar / identical ones for basic things like login, because there isnt really much to change from version to version

[quiet ice]

They don't change drastically yes, but noticably enough that you can't just plug and play

Again it is much like french and english. Many words are the same, but over time those two languages diverged so much that they aren't compatible [though here my comparision falls apart because french is latin and english germanic, but you get the drill]

[grave plover]

sad

[grave plover]

yep, then I have to rely on people that already bothered with it

I really thought that it could be easy-going... seems like I have to use protocollib / viaversion... do you have any record on their performance on a server? are they raising cpu load or anything?

[chrome beacon]

They're good enough

[grave plover]

ok, thank you

[glossy venture]

?mappings

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[grim hound]

they really are not

[grim hound]

don't you dare use protocol lib

packet events is the way

but they still won't be able to process different client to server versions without via version

[pliant topaz]

How would i go about making a specific item unmovable in the player's inventory?`This is my code currently but the event doesn't even get triggered

        System.out.println("MOVED");
        if (Objects.equals(CreateBoard.gameState, "RUNNING")) {

            System.out.println(event.getItem());
            if (Objects.equals(event.getItem(), PlaceVillageBlue.get())) {
                event.setCancelled(true);
            }

        }

    }```

Another option I tried was InventoryClickEvent which would be:
```public void InventoryClickEvent(InventoryClickEvent event) {

        if (Objects.equals(CreateBoard.gameState, "RUNNING")) {

            if (Objects.equals(event.getCurrentItem(), PlaceVillageBlue.get())) {
                event.setCancelled(true);
                System.out.println("Cancelled");
            }

        }

    }```

Still, both options don't seem to work. The first doesn't get triggered and the second one makes the item duplicate itself when picked up and it's movable with shift-clicking and also hotkeying.
Anyone knows what I've done wrong?

[peak depot]

can I change the default unknown command message with bungeecord so I dont have to put a plugin on every single sub server?

[chrome beacon]

InventoryMoveItemEvent is for hoppers

when they transfer items

[lost matrix]

InventoryMoveItemEvent is fired by hoppers, not players.
You need to cancel the InventoryClickEvent and drop event.

Ah and keeping it on death

[chrome beacon]

and DragEvent

[lost matrix]

Well this is covered by the click event

[chrome beacon]

better safe than sorry

[pliant topaz]

But cancelling InventoryClickEvent sometimes doesnÄt work

[lost matrix]

When?

[chrome beacon]

That would probably be because the drag event is firing

[pliant topaz]

When I shift-click it, it gets cancelled but after that I can just take it and nothing happens

Same with hotkey

[rotund ravine]

Are you in creative

[pliant topaz]

yes, why?

[lost matrix]

I havent cancelled this event in a year or so. Im pretty certain that cancelling the click event will completely the drag from being initiated.

[rotund ravine]

Creative is client handled mostly

So there is an InventoryCreativeEvent to try

[pliant topaz]

Yea, i jheard of it

[chrome beacon]

ah yeah player inventory and creative mode

[rotund ravine]

But otherwise creative breaks every inventory shit

[chrome beacon]

That's a pain

[pliant topaz]

K, I guess I'll try that

thank y'all

[grim hound]

since the BanList is not thread-safe, how can I asynchronously check whether a name is banned?

I cannot do it sync, since it's in the AsyncPreLoginEvent

and the PreLoginEvent is a menace to performance

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/scheduler/BukkitScheduler.html#callSyncMethod(org.bukkit.plugin.Plugin,java.util.concurrent.Callable)

[grim hound]

so I guess blocking the User Authenticator thread is fine because a new one is created on each join?

[lost matrix]

Yeah you can load user related data there for example.
Or check if someone is banned. Why are you trying to access the BanList there in the first place?

[grim hound]

I don't want to register the join attempt into my system if the user is banned

[ivory sleet]

Can’t you even read off it?

[grim hound]

what?

[ivory sleet]

I mean, sure it may not be 100% up to date

[quiet ice]

Async reading

[ivory sleet]

But usually even in a concurrent environment reading should be 100% fine

[grim hound]

have any of you ever worked with HashMaps?

[ivory sleet]

Yep

[quiet ice]

A bit dangerous, but as long as you aren't iterating it shouldn't be too bad

[lost matrix]

No, pls explain to me what it does

[ivory sleet]

I’ve implemented a couple as well in java

[ivory sleet]

This btw :)

Anyway I wasnt sure if you were talking about the existing banlist or ur own, custom one

[quiet ice]

You just may need to take a few precautions to make sure that you actually obtained the right entry in case the hashmap is getting rehashed when you obtained the value. But I think that should be rather easily possible in your case

[ivory sleet]

If its ur custom one, then its pretty fine to just load relevant data in APPLE from ur database or so

[lost matrix]

*PS: BanList is not a HashMap

[grim hound]

what?

[ivory sleet]

yeah, and if you use concurrent hash map then you’re basically gucci ganging

[grim hound]

1.20.2

[lost matrix]

Yeh the StoredUserList is backed by one. Doesnt mean you can infer thread (un)safety from it

[quiet ice]

Or you know, if the banlist is a singleton: Just sneakingly change the value of the map on the main thread via reflection or unsafe

[grim hound]

so the 1% of all situations

[lost matrix]

Here is the main problem. Even reading might trigger a bulk operation.
This means reading cant be done async. (Which is usually the case for normal HashMaps)

[grim hound]

yeeee

I knew I once found a problem with this

never actually got the error, but that doesn't mean it can't happen

[quiet ice]

Yeah then you need to read via reflection, at which point you might as well use reflection to make it thread-safe, at which point you might as well use your own banlist impl (probably possible I guess?)

[grim hound]

implementing my own banlist is a piece of cake

but I wanna remain full compatibility with the bukkit one

[lost matrix]

Or just callMethodSync and read from the list on the main thread while blocking the login for a few millis

[grim hound]

so I guess I'll just have to forcibly synchronize them

[quiet ice]

Well I was talking about also registering it to bukkit and substituting bukkit's banlist with it

[grim hound]

btw, since a few big boys are already here

how can I intercept the incoming connections, even before the async pre login event?

[lost matrix]

Just inject your own list with a concurrent hashmap instead 🙂

[grim hound]

oooo

[quiet ice]

But mah unsafe hackery

[grim hound]

you mean like

setting it to a ConcurrentHashMap

via reflection

[quiet ice]

Yes. And then get the value of the map

[lost matrix]

In the handshake. But there is not a lot of useful information coming from there.

[ivory sleet]

Or just dont use bukkits banlist at all

[quiet ice]

You probably need unsafe and not reflection though, given that it is a final field

[ivory sleet]

And have ur own system

[grim hound]

but how could I listen to it?

I only need the name and ip

[quiet ice]

You'll only get ip in the handshake iirc

[lost matrix]

Spigots earliest event is the AsyncPlayerPreloginEvent. Everything before that needs a packet listener or earlier interception on a proxy.

[grim hound]

and the name in LoginStart?

[grim hound]

I'll do the second one

or I'd do if I knew how to hook it up

can anyone lend a hand?

[quiet ice]

Isn't that AsyncPlayerPreloginEvent?

[grim hound]

nope

[quiet ice]

when is that handled then?

[grim hound]

I tested it

after the Encryption begin

so I think at the very end of the LOGIN phase

[young knoll]

Technically you can look up name via uuid

[grim hound]

is it sent in the handshake?

[ivory sleet]

W mojang api?

[grim hound]

my plugin aims at cracked servers

[ivory sleet]

Ah

Well I still don’t get why you don’t just have your own banlist thingy

Why do u need to base it on bukkit

Just curious

[grim hound]

to allow /unban and stuff to work

[ivory sleet]

Oh, I mean you could just simply have ur own commands

[grim hound]

I don't know whether it's better to

have it called sync via the bukkit scheduler

or override it with reflection

[ivory sleet]

The callSyncMethod is a bit meh as its bound to the game tick loop

[grim hound]

I tried that, but many people said they rather use Essentials and other command providers

[ivory sleet]

Hmm, I see

[grim hound]

I can add my own implementation since I already made a custom scheduler for bukkit

[grim hound]

(or rather Paper)

but it'd still need to wait for the tick loop

[ivory sleet]

If its sync, its pretty much bound to be following the game tick loop… yea

[grim hound]

since that's how synchronization works

[grim hound]

but a new thread is created on each user join

[ivory sleet]

Thats right

[grim hound]

blocking it shouldn't be a big problem

[ivory sleet]

No it’s completely fine to block it

I mean else I really liked the others’ suggestions about injecting some CHM in it all

but yes, you could simply do that

[grim hound]

CHM?

[ivory sleet]

CoconutHashMap

Concurrent*

[grim hound]

same thing

[ivory sleet]

Lol yea

[grim hound]

I guess I could do that at start-up

then I'll do just that

but one more thing

[lost matrix]

https://tenor.com/view/coconot-gif-22190312

[grim hound]

how do I add the connection interceptor?

like straight up a player requests to join

before the new thread is created

[ivory sleet]

I believe u can prob inject the netty pipeline before it all happens

Or something along those lines

[grim hound]

wouldn't it be still after the new thread is created?

also

how do I get their ip

[ivory sleet]

Unsure

[grim hound]

and how can I do it on spigot?

since on Paper there's some afterChannelInit stuff

[ivory sleet]

Doesnt APPLE have the ip stuff?

[grim hound]

apple?

[ivory sleet]

AsyncPlayerPreLogin

Event

[grim hound]

NICE

[ivory sleet]

Like it has an inet address so… thats the ip I reckon :>

Yea

[grim hound]

I know that

but that is WAAAAAY after the handshake

[ivory sleet]

True

[grim hound]

and the thread creation

hmmm

makes me wonder how ViaVersion does this stuff

[grim hound]

the user sends the server address?

not their own?

[dry hazel]

well the server already knows the user's address from the incoming connection

[lost matrix]

Wouldnt be very interesting for the server as TCP already has a source property, containing the sender address

[grim hound]

but why would they even bother sending the server's ip?

[grim hound]

how can I listen to that connection?

[lost matrix]

So the server knows from which sub-domain or proxy the client connected.

[dry hazel]

inject a handler onto the pipeline

[grim hound]

where

can you

elaborate?

[lost matrix]

I would probably use a packet library which already does this

[grim hound]

where can I get the pipeline?

@dry hazel ?

[quiet ice]

Somewhere in the nms player class I assume

[lost matrix]

Handshake is a bit different as the there is no actual client yet

[quiet ice]

Ah right yeah

There you'd somewhere need to find the global pipeline of the server socket

[dry hazel]

MinecraftServer#getConnection() and there you can inject your handler into the channelfutures, stored in a field iirc

https://github.com/ViaVersion/ViaVersion/blob/0e31664bfe4962c85fae6677bb17122f95c61616/common/src/main/java/com/viaversion/viaversion/platform/LegacyViaInjector.java#L43

[quiet ice]

why on earth did you ping me of all people?

Quite the opposite. Though I have no experience at all with bungee, so I can only give you the advice that you just throw things at the wall and see what sticks

Do beware that not every spigot plugin can be migrated to bungee/velocity (if you make a new stack from scratch, I'd recommend going with velocity, it seems like the better option of the two. Though arguably noone will go away anytime soon)

[lost matrix]

Highly depends on what your plugin does.
Spigot is an actual game server. Bungeecord is just a proxy which routes packets from A to B.
They are fundamentally different from each other.

[quiet ice]

Basically, if a plugin interacts with the world - then it is better that it is done via bukkit, not bungee.

[sterile sapphire]

It says “illegal start of type”

[quiet ice]

that can probably be migrated to bungee - simply change the bukkit/spigot dependency to bungee and fix all the errors that are caused by doing so.
However, I recommend going with a solution that already exists and learning how to work with bungee some other way.

[lost matrix]

This... does IO on the main thread if im not mistake. Not sure if i would want that on my server.

[quiet ice]

Porting generally requires good knowledge of both the source system and the system you are targetting your port at

[lost matrix]

Then there is a 0% chance of you converting this to bungeecord.
This can be ported but it will lose some of its functionality.

[sterile sapphire]

Could u guys help me with this error? It says “illegal start of type” and if u want I can send a pic of the code

[quiet ice]

Just send the actual code

[lost matrix]

Sounds like a simple syntax problem. Send code plox

[quiet ice]

While I could help you with like the basic things (e.g. what is the substitution of X), it is a bit pointless of a learning exercise for you

[sterile sapphire]

What are those things u send to make the code into a grey box :0

[lost matrix]

?codeblock

[undone axle]

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {

}

}```
Becomes:

public class MyPlugin extends JavaPlugin {
    @Override
    public void onEnable() {

    }
}```

[quiet ice]

Especially since you will need to get accustomed to a codebase you have not written yourself. Ordinarily both a blessing and a curse, but for porting (especially between systems this different) it just is a curse compared to writing it yourself.

[sterile sapphire]

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.checkerframework.checker.units.qual.C;

import static org.bukkit.Bukkit.getLogger;

public class CommandExecutor implements org.bukkit.command.CommandExecutor {

    @Override
    public boolean oncommand(CommandSender sender, Command command, String label, String[] args) {
        if (command.getName().equalsIgnoreCase("Test")) {
            if(sender instanceof Player) {
                Player player = (Player) sender;
                player.sendMessage(ChatColor.GREEN + "Success!");
            } else {
                getLogger().info( "This Command Must Be Ran By A Player");
            }
        }
            return true;
        }
        return false;

    } ```

[quiet ice]

In that case, just use something that already works. Programming is both easier (for people that already can do it well) and harder (for the laymen) than people expect

[lost matrix]

Which requires a very decent amount of coding experience.
As stated before: Spigot and Bungeecord are two completely different pieces of software that have very little in common.

[quiet ice]

And at what line is said error?

[lost matrix]

You are missing a closing bracket

[sterile sapphire]

so another 1 at the end will fix

[lost matrix]

Wait... no you have enough. Your return false; is just inside your class instead of your method.

[sterile sapphire]

so where should i put it?

Just format your code and it should be obvious.
What IDE are you using.

[sterile sapphire]

maven

[quiet ice]

(For eclipse: Ctrl + A, Ctrl + Shift + F)

[quiet ice]

Since when is that an IDE?

[lost matrix]

IJ its Ctrl + Alt + L

[sterile sapphire]

i think im getting confuised

[quiet ice]

Yeah. Chances are something else does that already - especially for a problem this common

[quiet ice]

Maven is a buildtool. An IDE is the programm you write your code in - so Eclipse, IJ or VS:Code

Please don't tell me you've been using Notepad this whole time

[sterile sapphire]

no

im using intelij

community version

[sterile sapphire]

i think i fixed the error but now i got 2 more im not familier with

me.tom.test.CommandExecutor is not abstract and does not override abstract method onCommand(org.bukkit.command.CommandSender,org.bukkit.command.Command,java.lang.String,java.lang.String[]) in org.bukkit.command.CommandExecutor

method does not override or implement a method from a supertype

[lost matrix]

Let your IDE resolve this. You didnt override the onCommand method properly.

[sterile sapphire]

i didnt see your message re right the code and now its fine 🙂

[marsh hawk]

Is there by any chance a known bug, which makes the player see through instead of invisible when applying invisibility?

[rotund ravine]

No

[chrome beacon]

That can happen with teams

it's a setting

[steel swan]

hey, i have an error telling me my world doesnt exist, even if it does.
here is the proof :

any idea?

[waxen plinth]

is it loaded

the world folder existing doesn't mean it's loaded

[steel swan]

its a single player world that was put here

[waxen plinth]

that doesn't answer whether it's loaded

[steel swan]

how can i load it then?

[sterile sapphire]

I deleted the jar on my project, I go to the lifestyle folder and compile but the jar file won’t remake its self

Could anyone help me?

[remote swallow]

what are you using to compile

well

what task are you invoking

[waxen plinth]

if you're not already, best to just use a world manager

[sterile sapphire]

I deleted the .jar file so I’m trying to re compile it

[waxen plinth]

like multiverse but I'm sure there is something better by now

[remote swallow]

what are you doing to recompile

[sterile sapphire]

I’m clicking compile

But it’s not working

[remote swallow]

run package

[steel swan]

so if i put a world in my server files, i cant just enter it?

[sterile sapphire]

It worked thank you!

[waxen plinth]

no

[steel swan]

so how do i do it ? i dont want to use an other plugin

[lost matrix]

Load the world

[remote swallow]

bukkit.yml might have a way to load it

[steel swan]

i asked how

[lost matrix]

Code

[steel swan]

Do you have any documentation or smth on how to load worlds?

idk how

[lost matrix]

Use a WorldCreator and apply the folder of your world as a name

[steel swan]

WorldCreator world = new WorldCreator(The name of the world);

Would this do it?

[sterile sapphire]

Ik I’m kinda in the middle on this convosation but I’m looking for a replacement of multiverse, what is a world creator?

[steel swan]

and when i do that, what do i do with the worldCreator?

[waxen plinth]

Bukkit.createWorld

[steel swan]

but wont this create a NEW world?

[waxen plinth]

only if it doesn't exist already

if it does it'll load it

[remote swallow]

that is how you get a world creator iirc

ah that just takes the world creator

[steel swan]

ohhhh thx !

it worked really nicely

[grim hound]

I'm just wondering but

If I close the netty connection

It kicks the player out and only shows one kick out message

And if I do it on handshake it can't be spoofed with the disconnect packet

So is there no way to replace it?

[modern basin]

Hello. We are looking for a MySQL money bridge, to save the vault eco balance to a database, and to be able to load that in a different server. Does anyone know such thing, or is anyone able to help me create this? I already found this one https://www.spigotmc.org/resources/ecobridge.94730/ but whenever someone is offline and gets money added, it doesnt save it to their data, so when they log back in it resets them to the old data

[sterile sapphire]

ive got the .jar file but when i put it in a server and star the server it apears red (isnt working) but idk why

[remote swallow]

check console

?paste any errors

[undone axle]

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

[sterile sapphire]

i checked it and it said the plugin disabled

its set to say that when its off

[remote swallow]

it should throw an error then

[pseudo hazel]

usually like a giant piece of red text

[remote swallow]

on paper, its all white on spigot iirc

[pseudo hazel]

oh my bad

[sterile sapphire]

yes i found it

its having a fit about the server being ran on paper but the plugin being spigot, i thought they were cros compatible

[remote swallow]

they should be

?paste the error

[undone axle]

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

[sterile sapphire]

this is the error

[remote swallow]

you didnt add the command to plugin.yml

[sterile sapphire]

i have

[remote swallow]

whats test.java line 11 and send ur plugin.yml

[sterile sapphire]

opps

it apears i have used diffrent names for the yml and the test.java line 11

silly me 😅

atleast i think its that

im gonna try it again

[sterile sapphire]

no its still not working

ill send that now

yml :

[median trench]

Does anyone happen to know why Minecraft custom item names infer that the text will be bold from one text to another (in the json form) when the first one is set to true, but ItemStacks don't, so cloning an item will remove the bold from the text parts that haven't set bold to true

[grim hound]

ItemStacks also do

If you mean custom names

Because I don't really get what you're saying

If one text is given an attribute, the others will also get it unless reset or set to another

[median trench]

Not at all, I have this command:
/give @p iron_helmet{display:{Name:'[{"text":"Ar","italic":false,"bold":true,"color":"#d16736"},{"text":"madura de Bron","color":"#f28e50"},{"text":"ce"}]',Lore:...
and it colours the name the first way.

But when I do e.getCursor().clone() (and put the ItemStack wherever) I get it coloured the second way.

Edit: ItemStack(e.getCursor()) does not fix this issue either

[eternal oxide]

Spigot or paper?

[median trench]

spigot api and paper server

e.g. what is Score mean, CNT etc

[lost matrix]

Depends on your benchmarking mode. Single shot? Average? Throughput?

[river oracle]

SampleTime

@Fork(value = 1, warmups = 1)
@BenchmarkMode(Mode.SampleTime)
@OutputTimeUnit(TimeUnit.MICROSECONDS)

[lost matrix]

Then it is the time measured for a single call on average with a random sampling strategy.
So 6.027 microseconds ber call with an median error of +/- 0.037 microseconds
(us/op = micro seconds per operation)

[river oracle]

ahhh okay

[lost matrix]

Cnt is the Count. So how many samples there are.

[river oracle]

what about score

[lost matrix]

?

-> 6.027 micros +/- 0.038 micros

[river oracle]

mmk

[lost matrix]

p0.50 is the 50th percentile. So the worst 50%
p0.9999 is the 99.99th percentile. Showing the worst 0.001%
p1.00 is therefore the single worst measurement.

[river oracle]

ohhh okay

so the goal would be not to have a large spread or is that kind of just inevitable

[lost matrix]

It depends on what you want to measure. Usually everything beyond the 99th percentile is disregarded as
there will always be outliers like random bit flips, other processes or quantum effects like random tunneling,
making a perfect run impossible.

[lost matrix]

If you want to measure the time complexity of a data structure or algorithm O -> n, then you need to
measure multiple times while increasing n, where n is ususaly the number of elements.

So for measuring

n=1   ->  2ms
n=10  ->  20ms
n=100 ->  200ms
...

you detect a linear increase in time, which means the measured algorithm is O(n)

For a (perfect) hashmap contains it should be constant

n=1   ->  2ms
n=10  ->  2ms
n=100 ->  2ms
...

Meaning O(1) as O is disjunct from n

[shadow night]

what other kinds of time complexety are there

besides O (1) and O (n)

[quaint mantle]

log

nlogn

[quaint mantle]

lmao n!

[river oracle]

technically an infinte amount

as you can modify N in a ton of ways

[lost matrix]

The most common ones are [In decreasing performance]
O(1) constant time
O(log(n)) logarithmic time
O(n) linear time
O(n^2) quadratic time
O(e^n) exponential time
O(n!) factorial time

But there is actually an infinite combination of time complexities because algorithms can be chained.

[river oracle]

thank you

[quaint mantle]

O(n^n)

[shadow night]

my favourite

[quaint mantle]

any algorithm that works like that?

[kind hatch]

Probably

[shadow night]

shit

[quaint mantle]

Every python algo: n^infinity

[river oracle]

honestly anything e^n and above probably shouldn't be used unless their is no alternatives

[lost matrix]

Its pretty much exponential time with e being directly coupled to n.

Recursion usually results in e^n pretty quickly. Combine it with O(n) as a base like a simple iteration and you got n^n

Cant think of anything concrete rn. Probably because its so bad.

[ivory sleet]

Yeah big O notation disregards smaller details, but just denotes the general behavior of a function, like n^2 + 10 is still just n^2

Which is why also time complexity is just a good way of telling how an algorithm scales, if each operation takes 1 minute in an algorithm its gonna be slow even when n= 10 and O(n) for instance

[quaint mantle]

Thinking Big O of bogo sort

[proud badge]

could someone translate to english what this ConcurrentModificationException is
https://paste.md-5.net/itiwawixad.php

[quaint mantle]

You cant iterate and delete stuff at the same time

Like
list.forEach((a) -> list.remove(a))

[shadow night]

List list = new ArrayList();
for element in list:
 list.remove(element)
``` some pseudocode

[proud badge]

something like this you think could be causing the problem?

[quaint mantle]

No in for scope

[proud badge]

This code is mostly ran async

[quaint mantle]

Do queue for modifing the list

Sync stuff

[proud badge]

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

[proud badge]

this is in onEnable

[lost matrix]

You cant randomly access other peoples api async and pray its thread safe...

[shadow night]

Yep

Why do everything async, it's such a pain in the ass

[proud badge]

Database lookup

[lost matrix]

Nothing in spigot is thread safe unless specifically stated

[shadow night]

Spigot is spogit

[proud badge]

so by how I understand ConcurrentModificationException happens when you try to delete a list element whilst looping through it?

[shadow night]

Yes

[proud badge]

Ok hmm I'll try to think of something to fix that

[lost matrix]

You should def refactor your code. Im seeing a metric ton of repeated code.
It will make it much easier to separate what can be done async and what can be done sync.
And helping is much more efficient.

[shadow night]

I usually just have a second list, after looping I just do firstList.removeAll(listToRemove)

[lost matrix]

There are two approaches.
Iterating using .removeIf() or creating a second collection, adding elements and removing them after the iteration with .removeAll()

[proud badge]

for those of yall who dont understand what the code is for: I need to check if a block is natural with coreprotect onBlockBreak, instead of opening a new thread for every block I queue them up and async loop through the queue every second

[lost matrix]

[ivory sleet]

Isn’t there like some sort of callback or anything more reasonable you can do rather than polling it manually?
