    private HashMap<UUID, Long> cooldown = new HashMap<>();
    @EventHandler
    public void onAsyncPlayerChatEvent(AsyncPlayerChatEvent e){
        Player p = e.getPlayer();

        if (!cooldown.containsKey(p.getUniqueId())) {
            cooldown.put(p.getUniqueId(), System.currentTimeMillis());
            return;
        }

        long timeElapsed = System.currentTimeMillis() - cooldown.get(p.getUniqueId());

        if (timeElapsed >= getConfig().getInt("chat-cooldown")) {
            cooldown.put(p.getUniqueId(), System.currentTimeMillis());
            return;
        }

        int remaining = getConfig().getInt("chat-cooldown");

        e.setCancelled(true);
        timeElapsed = remaining - timeElapsed;
        p.sendMessage(Utils.color(getConfig().getString("chat-cooldown-reached").replace("%seconds%", String.valueOf(Math.round(remaining/1000)))));
    }```



it doesnt work correctly and when i am on cooldown and i send a message it actually cancells the event but doesnt say anything except for this error in the console https://pastebin.com/wARyV11H

anyone know why?

[sterile hinge]

it exactly tells you what's null

[urban temple]

Yea but idk why it is

in the config everything is correct

https://pastebin.com/EN09q2Zb

this is the config

[merry knoll]

whats at row 229?

[urban temple]

        p.sendMessage(Utils.color(getConfig().getString("chat-cooldown-reached").replace("%seconds%", Integer.toString(Math.round(remaining/1000)))));```

[merry knoll]

^ thats where the null is

maybe your config in your server is not updates?

updated**

[urban temple]

it is, also i had it in the config for a long time but im just recoding the cooldown system

[sterile hinge]

the path is messages.chat-cooldown-reached

[merry knoll]

ah yes

[urban temple]

Ohh, thanks!

[nimble vale]

hey i have 2 projects that each depends the other one

both projects have errors because project A use some code from the B but
also project B uses A i need to use publishToMavenLocal but i can't because projects have error again

i don't know what to do rn

maybe i can remove all imports from a project but it's the last option

also using gradle for both

i guess the problem can be easily solved by ignoring errors when i run publishToMavenLocal but how can i do that

[high edge]

Why do the projects depend on eachother?

[nimble vale]

actually 2 plugins

well it depends because

idk if the structure is wrong

but it seems that it makes sense

[high edge]

If they depend on each other, then it doesn't really make sense

[nimble vale]

one of them is a plugin for a minigame all stuff inside it
and the other is a weapon plugin

for example
i need to give weapon in minigame plugin and check teams for weapon plugin

[high edge]

the weapons plugin shouldn't rely on the minigame plugin at all

[nimble vale]

well i need to check shooters and the victims teams

maybe i can create a custom shooting event for that but yeah

[high edge]

Your weapons plugin should provide everything necessary, but not handle it

[nimble vale]

i can divide it into like 3 plugin and create a new one to handle common things

but thats not really practical rn

yeah i guess i need to make a common plugin and events for the weapon plugin

[lyric gyro]

weapons plugin should provide weapons functionality only

minigames plugin should take advantage of the fact the weapons plugin is present and make use of it, adding all the minigame-related features to it

rather, bringing weapons into the minigame uh ecosystem (?)

[nimble vale]

so i just need to add an event for the weapon plugin and check the teams in minigame plugin

[lyric gyro]

it's probably gonna be more than just "an event"

anything that makes one plugin interact with it to make things works smoothly

what that is and how you do that depends on how you've structured the weapons plugin, nothing I can really tell you

[nimble vale]

yeah i was just trying to ignore the errors for a while to add dependencies

but i need to change the structure first

[queen plank]

How do I support multiple different versions for a plugin? I for example have a way of filling an area with a material entered in the chat, the material is selected via Material.valueOf(). How would I do this with say 1.18 and 1.19 since they include different materials? I assume I list them both as dependencies in the pom and then use different classes for it. Would I then have a "place block" function that takes in a string, gets the spigot version and redirects to the correct class from there? And does that mean I have to rewrite the same chunk of code for each version?

Pls ping if you respond :>

[lyric gyro]

Material.valueOf(String) doesn't work any different between versions

If the player types "STONE" then stone will be on every version, if the player types "COPPER_ORE" then it'll work if the server version contains copper ore, it won't work if the server version doesn't contain copper ore

At most put the valueOf inside a try-catch block, catching IllegalArgument in case the entered text is not an enum constant

[trail burrow]

I'm getting errors I can't figure out, I may of found the issue, this should not return null right? getLogger().warning(String.valueOf("mainclass = " + this.getServer().getPluginManager().getPlugin(Library.AURELIUM_SKILLS.getInternalPluginName()))); [21:11:54] [Server thread/WARN]: [Autorank] mainclass = null

[forest jay]

depends on what Library.AURELIUM_SKILLS.getInternalPluginName() returns

also, what are you trying to achieve?

[trail burrow]

internal name of plugin called Aurelium Skills

maybe I'm not getting that info right

[forest jay]

Why not just put a string literal?

Something like Aurelium Skills or, if this is getting your own plugins instance, I would suggest creating a static instance, and set it in your on enable, along with a static getter.

[trail burrow]

I need to see if the plugin is installed or not

[forest jay]

this is how I do that when registering my papi expansion: ```java
if (Bukkit.getPluginManager().getPlugin("PlaceholderAPI") != null) {
new PAPIExpansion().register();
}

[trail burrow]

thats what I have but don't work

[forest jay]

then the plugin name is wrong

are you sure that Library.AURELIUM_SKILLS.getInternalPluginName() returns the plugin's actual name, that is defined in the plugin.yml?

[trail burrow]

I know why it is null I need to install the plugin

[forest jay]

yeah, if it isnt there, it will return null, if it is there, it will give you a JavaPlugin instance

[trail burrow]

making to many mistakes, will be done soon

[forest jay]

all good, I still make mistakes like that lol

[trail burrow]

he has AureliumSkills vBeta 1.3.6 for internal name

[leaden sinew]

So I'm having issues with generics (again).

Shouldn't this work? Or is it not known at compile time?

final DatabaseColumn<String> column = DatabaseColumn.builder("first_column").
        // Required type: DatabaseType<java.lang.Object>
        // Provided: DatabaseVarChar
        type(DatabaseTypes.ofVarChar(32)).
        key(DatabaseKey.PRIMARY).

public static class Builder<T> {

    private Builder(String name) {
        this.name = name;
    }

    public Builder<T> type(DatabaseType<T> type) {
        this.type = type;
        return this;
    }

// class is 
// public class DatabaseVarChar extends DatabaseType<String>

// DatabaseType class is:
// class DatabaseType<T>

public static DatabaseVarChar ofVarChar(int length) {
    return new DatabaseVarChar(length);
}

Please ping me if you know the issue, thanks!

Nvm I'm dumb

Had to do DatabaseColumn.<String>builder("first_column") and I was going DatabaseColumn<String>.builder("first_column")

[sterile hinge]

hey it makes sense this way besides the missing type inference

[queen plank]

I want to prevent players from dropping items in creative. It works fine if the player has their inventory closed and clicks q (ctrl + q works too), however if the player has their inventory open and clicks q or ctrl + q on the item it just disappears. Any idea how to fix it? I currently just listen for a PlayerDropItemEvent and cancel it. However when I drop it from the inventory the event is not called for some reason, and I can't use a InventoryClickEvent as the click type will be CREATIVE and I don't want to block slot change.

[dense drift]

There's ClickType.DROP for InventoryClickEvent

[queen plank]

Yeah ik, but that is replaced with ClickType.CREATIVE if the player is in creative and has their own inv open

For some reason

[dense drift]

I see

[proud pebble]

creative inventories are irritating af

i wish they were serverside

or atleast sends more packets

[sudden sand]

Why my custom model data removes itself when I got creative mode ?

(it's an armor item)

nvm it was because of exploitfixer

[trail burrow]

I have tried many combos and can't get this error to go away https://paste.helpch.at/disogicaqa.md it only happens after a minute a player joins, then spams every minute after that.

[dense drift]

code?

When I try to click that same phantom membrane to reopen the inv, inv doesn't open either.

I am sorry for such long message

But i have gotten it down to that what i am saving to PDC is nothing- so most likely that is causing the Exception when it tried to deserialize it.

[lyric gyro]

I'm your close inventory listener stop using getItemMeta all the time, gIM returns a copy of the ItemMeta, so this line heldItem.setItemMeta(heldItem.getItemMeta()) is effectively doing nothing; put the meta in a variable, modify it all you want and then use it in setItemMeta

Also for deserialising you are using a BukkitObjectInputStream, don't, use a regular ObjectInputStream

@obsidian sonnet

Although in reality ObjectStreams should not be used either, and use a DataInput/OutputStream instead but it's not the end of the world because of that

[obsidian sonnet]

Alrighty, I will try what you have suggested. Thank you.

[trail burrow]

@dense drift that's the weird part the cause don't point to my plugin, unless I'm reading it wrong, when I updated to the latest Aurelium Skills to Autorank and everything works fine as long as server has Aurelium install

        return isPluginAvailable(Library.AURELIUM_SKILLS);
    }

    public boolean hook() {
        return isPluginAvailable(Library.AURELIUM_SKILLS);
    }``` for checking if plugin is installed

[dense drift]

what does that method do?

[trail burrow]

checks skill levels, stats and mana

[dense drift]

I'm talking about isPluginAvailable

You might access a class from AureliumSkills before checking if it is enabled

[trail burrow]

I thought it was a bukkit think guess I will find that method

        Plugin plugin = Bukkit.getServer().getPluginManager().getPlugin(library.getInternalPluginName());
        if (plugin == null) {
            return false;
        } else {
            return !library.hasMainClass() || plugin.getDescription().getMain().equalsIgnoreCase(library.getMainClass());
        }
    }```

[obsidian sonnet]

Hmm it seems that something with my ByteArrayInputStream bis = new ByteArrayInputStream(bytes); ObjectInputStream ois = new ObjectInputStream(bis) is causing the [20:30:34 INFO]: java.io.EOFException as it still happens when I apply the changes you have suggested, but now the byte array actually has information in it.

[queen plank]

How do I get the direction a living entity is looking as a Vector?

[lyric gyro]

entity.location.direction

[lyric gyro]

Alright I'll check in a few minutes, it seemed like it should work

[queen plank]

I thought that was a Vector pointing from 0, 0, 0 to the location :V

🧠

Thnx

[lyric gyro]

Well, Location as a Vector itself is that, but Location also has yaw and pitch, that's what its direction is :d

[queen plank]

I just realised that that makes so much more sense. I thought that was stored in the entity for some reason

lol

[lyric gyro]

Well you see, in the vanilla code, it is

But Bukkit is stupid

[obsidian sonnet]

Alrighty, jus ping me once you have a suggestion or solution.

[worn jasper]

Uhm, If I use the holograhpic display's api, when you create a hologram, you name it, does that also show in /hd list? Cause like, I want to create A LOT of holograms, and I don't wanna spam the list and hide actual holograms that may need to be changed

[dense drift]

most likely not

[merry knoll]

just test?

but honestly, if its not per person (aka placeholders etc) just use armor stands with ticking disabled

[worn jasper]

setCanTick(false)?

[worn jasper]

k thx

Uhm, any ideas why this might be not working?

Consumer<Chunk> consumer = chunk -> {
  ArmorStand as = (ArmorStand) chunk.getWorld().getEntity(uuid);
  if (as != null) as.remove();
};
loc.getWorld().getChunkAtAsync(loc, consumer);

Like, I am 100% sure the armorstand with that uuid exists.

And well, it only gets executed when the chunk is loaded right?

so, what could be causing issues

quite confused

[lyric gyro]

println(armorStand)

[sterile hinge]

What part isn’t working as expected?

[lyric gyro]

yes

[worn jasper]

deletion

[worn jasper]

eh I can't rlly replicate it since it happens sometimes with players on the server

not always

tried replicating it and didn't work soo

unsure if adding that will help much

[sterile hinge]

So the entity is null or does it call the method?

Also, does it only happen if the chunk isn’t loaded?

[dusky harness]

println(armorStand)

[lyric gyro]

it's called debugging

Also, entities are loaded separately from the chunk

There's a EntitiesLoadEvent now

Maybe that's why? No idea

But please print stuff, it's called debugging, it helps everyone help you

[worn jasper]

I am aware of what it is lol. Also, if entities are loaded separately then how can I load them? Cause if they aren’t loaded, I can’t get them

[sterile hinge]

IntelliJ Debugger 😌

[sterile hinge]

pretty sure it should work if you delay it by one tick

[worn jasper]

Delay what exactly, the deletion? I mean, it only doesn’t work sometimes so how would that change anything?

[sterile hinge]

the getEntity call

I assume it works when the chunk is already loaded

[worn jasper]

Yes

But everything is sync, shouldn’t it wait for getEntity to return? Lol

Quite confused on how a delay could do it

[sterile hinge]

meh the methods to get the chunk directly only if it's loaded aren't exposed as it seems :/

[sterile hinge]

that's not the problem, but the entities aren't added to the chunk in the tick the chunk is loaded

[worn jasper]

Oh, so why does it works sometimes and sometimes it doesn’t?

[sterile hinge]

.

I'm not the one sitting in front of it, so you'll know better what's going on

[worn jasper]

Nono, even after that

I already tested it

[sterile hinge]

I can only tell you what I remember from 2 1/2 years ago

[worn jasper]

Sometimes it works as intended

And it loads the chunk

And gets the entity

[sterile hinge]

how do you know the chunk wasn't loaded?

[worn jasper]

Well I left it, no one was loading them for like 30 minutes, just a plain chunk with nothing in it

[sterile hinge]

so you assume the chunk wasn't loaded?

[worn jasper]

I suppose yes.. good point….

How do i fix said java.io.EOFException

[lyric gyro]

hmm

can you change this

try (ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(bos)) {
  writeInventory(inventory, oos);
  return bos.toByteArray();
} catch (IOException e) {
  System.out.println(e);
  return null;
}

to this

try (ByteArrayOutputStream bos = new ByteArrayOutputStream()) {
  try (ObjectOutputStream oos = new ObjectOutputStream(bos)) {
    writeInventory(inventory, oos);
  }
  return bos.toByteArray();
} catch (IOException e) {
  System.out.println(e);
  return null;
}

@obsidian sonnet

[obsidian sonnet]

Yeah sure one sec.

It works, can you explain what exactly you changed that caused it to work? So I know for future reference.

[lyric gyro]

Some output streams buffer/store data you put into them before "sending" it to the other stream (in this case, the object stream buffers/stores some of the data before sending it to the byte array stream)
Output streams can be flushed, meaning it will send immediately any data they might have buffered; what using a try-with-resources does is, when your code exits the scope of the twr it will be flushed (and also closed)

  try (ObjectOutputStream oos = new ObjectOutputStream(bos)) {
    writeInventory(inventory, oos);
    // inside the scope of this try-with-resources
  }
  // outside of this scope of that twr, oos is flushed and all its buffered data is written to the bos

So moving it that way you basically ensure the data you need from the "outer stream" is actually written into it once you're done with the "inner stream"

[obsidian sonnet]

Ahh alright, thank you for the help!

[lyric gyro]

I didn't know OOS buffered stuff lol

[formal crane]

I am trying to Iterate through a hashmap, but all things that i found online don't work for me (when i hover over it it says its abstracted and cant be used)

example of what i tried:

        if (x < 0 || map.size() < x) {
            throw new IndexOutOfBoundsException();
        }

        Iterator<Map.Entry<String, Location>> it = new ListIterator();

        for (; x > 0; --x) {
            it.next(); // ignore the first x values
        }
        return it;
    }```

(btw i am trying to get the next item in the hashamp from a specific index)

[dense drift]

HashMap doesnt preserve order btw

[formal crane]

so if i do this

map.put(k1, v1);
map.put(k2, v2);
map.put(k3, v3);

it will not stay like that?

[broken elbow]

it will, if its a hash map

[formal crane]

i meant the order

i am gonna use a linkedhashmap because the order is important

[broken elbow]

oh yeah. yeah. my bad

linked hash map not hash map

[sterile hinge]

if order is important, you might need to reconsider your usage of a map

[queen plank]

Can someone tell me why this takes three seconds for my PC to do? I'm not doing anything else on my pc when I run it. https://paste.helpch.at/zupahiruru.cs. The time is printed using System.currentTimeMillis()

[icy shadow]

🤨 🤨 🤨

all you're doing is calling a constructor?

[queen plank]

Yeah, I had more code there b4

To validate some variables n stuff

[icy shadow]

double check you're not using old code

[queen plank]

But how can it take 3s

wdym

[icy shadow]

this

there is absolutely no way that a single constructor call takes 3 seconds

even if you're using a potato

Conditions.assertNotNull could also be doing something funky but i doubt it

[lyric gyro]

that function seems to be as fast as it gets, look at the times lol

[icy shadow]

yeah so something else is severely wrong

[lyric gyro]

inb4 allocated 64GB to the JVM and it's time for a GC cycle

[queen plank]

public static void assertNotNull(Object o) {
if (o == null)
throw new ConditionException();
}

That is it lol

Idk what it all is abt

This 3s time

[icy shadow]

thats the only thing i can think of

nothing else makes sense

[queen plank]

???

What Emily said

What does it mean :V

[icy shadow]

you dont have any free memory and so the jvm needs to free some up

this is extremely unlikely

[queen plank]

Very

I allow it to use 32 GB, and all 8 files I load that way all take 3.5s exactly there

[icy shadow]

hang on hang on

"load"

are you actually reading the files at all

[queen plank]

I am

But I did not include the code in the paste

I read it further down

After the 3s delay

[icy shadow]

are you sure

[queen plank]

Yeah

[icy shadow]

then i have no idea

run a debugger / profiler maybe

[trail burrow]

is jstat Kotlin?

[icy shadow]

no...?

it's literally made by oracle and part of the jdk lmao

and has "J" at the start not "K"

[trail burrow]

for some reason it is not in my JDK then

[icy shadow]

old version?

[trail burrow]

jdk 16

it just started to work, go figure

watching a video on nested classes and wanted their code to play with till I understood it

[trail burrow]

ok now that I have hit a brick wall I need a little help I'm working on Nested Class a local inner class I can't call the method on main class https://paste.helpch.at/ixewecijod.java nested class https://paste.helpch.at/ewudivipoq.java

[proud pebble]

there is no reason to nest classes

judt use them as methods

[trail burrow]

either way I want to try to see if this will fix my issue

[lyric gyro]

those aren't nested/inner classes

they are local to the method

they only exist within the method they are declared in

if you want to access them from the outside, either make them inner classes

class Outer {
  class Inner {
  }
}

or just a whole separate class altogether

[sterile hinge]

(did you know you can have local interfaces, local enums and local records too since Java 16?)

[queen plank]

I want to allow for the use of alias commands. As default I have a command that is /cage, say the owner wants it to be /walls, how do I make it register? I can't include it in the plugin.yml as I don't know the commands when I compile the plugin.

[merry knoll]

you can register it through reflection most likely

not sure if the internal bukkit command map is public

[flint kernel]

the commandmap is public on paper but not on bukkit or spigot

[wheat carbon]

have a feeling the command needs to be entirely dynamically registered if going that route

iirc you can't modify entries already in the command map?

idk matt knows more about it

[merry knoll]

could just register a new command with the alias

and hook them up inside the plugin

[trail burrow]

@lyric gyroI re-watched the video and realize I was to tired the first time I watched it

So my if statement will activate for things such as if you name a dispenser in an anvil called backpack and open and close it. which then throws an error bc of null item meta etc. Is there a way to get around this from happening?

[trail burrow]

https://paste.helpch.at/cuwecadoti.java this works as long as I have Aurelium Skills install, I get this error when I don't have Aurelium installed https://paste.helpch.at/usunawilul.md

[merry knoll]

whats at library 88

[trail burrow]

an enum

AURELIUM_SKILLS("AureliumSkills", AureliumSkillsHook.class, "Archyx"),

[merry knoll]

you cant use a class from a package you dont have

AureliumSkillsHook.class this wont work if you are lacking the dependency

wait, is that from the dependency even

[trail burrow]

I have 21 other hooks setup this way and they work fine

[merry knoll]

just realized its your class name

[trail burrow]

this one worked before they changed their API

if I remove all code that checks the data required in the plugin it works fine, with or without the plugin. it hooks or dont hook

[merry knoll]

you are trying to access com/archyx/aureliumskills/skills/Skill

somewhere

[trail burrow]

nowhere in my code I have that, it's com/archyx/aureliumskills/skills/Skills

[merry knoll]

me.armar.plugins.utils.pluginlibrary.Library.getHook(Library.java:88) its here

[trail burrow]

that is only ``` public Optional<LibraryHook> getHook() {
if (this.hook == null) {
try {
this.hook = this.libraryClass.getDeclaredConstructor().newInstance();
} catch (NoClassDefFoundError | Exception var2) {
Bukkit.getLogger().info("Could not grab hook of " + this.getHumanPluginName());
var2.printStackTrace();
return Optional.empty();
}
}

    return Optional.of(this.hook);
}```

no imports in that class for Aurelium

[merry knoll]

well there wont be since you are using this.libraryClass

this.hook = this.libraryClass.getDeclaredConstructor().newInstance(); cant do this on an dependency you dont have

[trail burrow]

that code above is in Library.class

[merry knoll]

this is fine though no?

your code returns an empty version i assume if it doesnt exist

and the "error" is just the stacktrace

var2.printStackTrace(); from here

[trail burrow]

I didn't write this part of the code, I am trying my best to understand it

[merry knoll]

if you dont want it printed (and you handle that dependency not existing) then stack trace is not needed

try {
// get a new instance of the class provided
catch // class doesnt exist {
// do stuff if class doesnt exist
}

thats what it is doing

and it returns return Optional.empty();

whatever this is

if you dont want the stack trace on the console

remove this line

var2.printStackTrace();

but make sure you that you dont use the hook (aka the dependency) anywhere else if it returned an Optional.empty()

otherwise, you will get the exact same error again

[trail burrow]

I went on the assumption I didn't something stupid with imports and I delete the class and remade it

nope still give error

[merry knoll]

imports wont cause that

you need to use the class to get that issue

as in the code needs to run

[trail burrow]

when I remove the imports and any errors that come from doing so the error goes away, my guess the issues is with Aurelium Skills not my code

[merry knoll]

yes, since then you dont actually "hook" to their code

[trail burrow]

I put a check in the stacktrace to ignore aurelium skills

no it still hooks, just don't get the data required for the checks

[merry knoll]

data?

if you could share the code it would be way easier to diagnose

[trail burrow]

yes like xp for a skill

[merry knoll]

obviously

you cant pull the xp if the plugin doesnt exist

[trail burrow]

I'm done, testing for timing issues now, so far none

[merry knoll]

alrighty

[trail burrow]

I was thinking of adding a new feature in AR if a server owner was to change Lang file to be blank how do I get it not to send to chat? I assume it has to do with a if then or maybe something even eaiser

[broken elbow]

just an if I guess? have a custom send message method, and just check if message is not empty, and if it isn't send

[trail burrow]

guess I should make a custom send message so there would be less trouble shooting in future

[broken elbow]

it will save you from bad memory, and also from a lot of duplicated code

any ideas why? or am I just stupid?

yes you are

look closely at the itemList type

I'm trying to send email from java and for some reason I get this execption

Please ping if you fine think you know what caused this exception and how to fix it.

[dusky harness]

☹️ I'm having that issue too

|| I just overrided the implementation so that it doesn't check that 🥲 ||

[obsidian abyss]

but this is not secured and puts your machine at risk

[dusky harness]

ik but its for a private project and I spent way too many hours on getting this to work with cloudflare

[obsidian abyss]

is there another way?

to get that certification?

[dusky harness]

probably, but I couldn't find any

I think it means that the certification is invalid

or something

¯_(ツ)_/¯

[obsidian abyss]

ik but how can I get one..? anyone?

[slim estuary]

Hello, I'm looking for some advice.

I've developed a plugin which collects stats about the player as they play (what blocks are broken / placed, etc.). I'm storing all of this information of my mySQL database. Now, if I wrote to the database every single time a player interacted with the world, the server wouldn't like it too much. So instead, I've decided to store all of the SQL statements to a temporary list (stored as a string), and every so often, a task would iterate through the list and execute each of these SQL statements. This seems to work fine; however, as a result of this the data can sometimes take a little bit to update. Also, if the server were to shutdown or crash for any reason, some of these statements wouldn't get executed,

Is this solution good? Or is there a better way to manage many inserts and updates to the database at any given time.

I'm using HikariCP if that helps any.

[merry knoll]

instead of doing an interval

you could count the changes and update every x changes made

but the interval solution is what people use usually

(or if the data is not that important, load on player join and save on player leave and plugin disable)

[merry knoll]

one thing thats actually an issue though is storing the sql statements as string, keep the player data in a wrapper class of sorts and update using that

its usually not an issue, but using prepared statements is highly recommended

which you cant do with just sql statement as string

[mental cypress]

Couldn't you just store that data on the PDC of the player and then on an async interval task update the DB with those numbers?

Assuming you're using a more recent version of the game.

[merry knoll]

i never understood the reason for PDC personally, wouldnt a hashmap/set serve the exact same purpose?

[slim estuary]

I don't have many players, so updating every x amount of changes or on a join / leave event would be noticeable, since in addition to storing these stats, I have a tasks system that shows the users which blocks to interact with to complete it (for example).

I am making use of PreparedStatements, and I just build it with the string I store in the list.

Here's how my table is setup.

+--------------------------------------+----------+-----------------------+--------+
| user_uuid                            | type     | material              | amount |
+--------------------------------------+----------+-----------------------+--------+

Could I even store all of these things in a persistent data collection?

[mental cypress]

I mean yeah, it's just it'll come back if the player logs out or whatever. It just sticks to them.

[merry knoll]

guess you dont really need to handle it yourself with pdc, kinda trivial but eh

[mental cypress]

Correct

It's just up to the person

[merry knoll]

async timer is what you want to go with most likely

but, i would hold the data instead of the sql statements

[mental cypress]

I have a server that removed the need for chests because we implemented our own chests that don't tick so it helps server strain and fps to the players.

Utilizes PDC

[slim estuary]

Does this work?

 Bukkit.getScheduler().scheduleSyncRepeatingTask(this, () ->
            Bukkit.getScheduler().runTaskAsynchronously(this, SQLDatabase::executeQueries), 20, 200
        );

[merry knoll]

10 seconds is a bit too fast honestly

most wont cry over 5 - 10 minutes of data lost

but if you absolutely want to use fast updates

then keep using hikari or any other pooling solution

since opening connections can be quite heavy

[merry knoll]

you want async not sync

[slim estuary]

Inside of the executeQueries() I just open 1 connection and use connection.prepareStatement(string) inside of the loop.

Closing each statement

[merry knoll]

if you are using hikari then you dont open or close anything

close returns the connection to the pool and open just gets one from the pool

they stay open

[slim estuary]

Even closing the PreparedStatement?

[merry knoll]

thats closing the statement

not the connection

once you close the statement and call .close() on your connection

that connection is returned to the pool

[slim estuary]

Okay yeah

[merry knoll]

you also want this

.scheduleAsyncRepeatingTask

no need to create another scheduler

[slim estuary]

It says its deprecated

[merry knoll]

runTaskTimerAsynchronously is the new one i think?

[slim estuary]

Yeah that one works

[slim estuary]

Could you elaborate a little further?

[merry knoll]

you can either store the data in a PDC

on each player

or just create a class to hold it

and store it against uuid in a hashmap

So my if statement will activate for things such as if you name a dispenser in an anvil called backpack and open and close it. which then throws an error bc of null item meta etc. Is there a way to get around this from happening?

[rigid mountain]

Hey guys question, so im saving an array of itemstacks to mongo, but when i load the object i get this error: java.lang.RuntimeException: Unable to invoke no-args constructor for interface org.bukkit.inventory.meta.ItemMeta. Register an InstanceCreator with Gson for this type may fix this problem. anyone know how to fix?

[dusky harness]

don't serialize itemstacks directly

probably

[rigid mountain]

Hmmm, so i shouldnt just save the array?

[dusky harness]

well I think there's like ItemStack#serializeToBytes or something

then serialize that

might be a paper method though

[obsidian abyss]

how can I send an html email with css?

not embedded css

a file or either a link

[dense drift]

The css has to be in the same document, or hosted somewhere I believe

[obsidian abyss]

ok

it is working with a static html page or a website but when sending a mail as that html the styling disappear

[dense drift]

Maybe is just the client that doesnt render it

Also, make sure you set the content type to text/html or whatever is for html

Hey, got some gradle questions

I have two modules:
clans-plugin and clans-plugin-legacy
clans-plugin-legacy depends on clans-plugin.

clans-plugin has a lots of dependencies, which has to be relocated. The problem is, when i build clans-plugin-legacy dependencies from clans-plugin are not being relocated. how can i have common relocations between two modules?

I think implementation(project(":clans-plugin", "shadow")) should do it

it's uh mentioned somewhere in the gradle docs

err, shadow* docs

you are my life saver

Hi, if I have this switch:

var material = string.split("-");
switch (material[0]) {
    // Code here     
}

If material doesn't contain any "-", it won't split, will it cause any errors or will the switch statement run default (If I add it).
Asking this here cause I can't really test it rn. I don't have minecraft installed rn.

[worn jasper]

Hmm, so it just returns 1 string okay... so I would have to check if material[1] exists for example, to know if it was split or not.

Thanks.

[honest bronze]

if this is user input check the length of the split too, a string containing only - will return an empty array

This is my code

        WrapperPlayServerEntityMetadata playOutEntityMetadata = new WrapperPlayServerEntityMetadata();

        WrappedDataWatcher watcher = new WrappedDataWatcher();

        if (this.sneaking) bitMask = 0x02;

        System.out.println(bitMask); // works

        watcher.setObject(0, serializer, bitMask);

        playOutEntityMetadata.setEntityID(this.entityID);
        playOutEntityMetadata.setMetadata(watcher.getWatchableObjects());
        playOutEntityMetadata.sendPacket(player);

Uhm is there any Map that sorts the data by well, when it was added? unsure how to explain, just like a list where .get(0) would get the first item that was ever added to it.

which welp, isn't what I wished for

[icy shadow]

LinkedHashMap

[worn jasper]

ok ty

[stuck canopy]

hey

Is there a way to change player's uuid?

[sterile hinge]

the reason for UUIDs was to be able to change names while keeping a unique identifier

[stuck canopy]

so what else can I use to re-create Hypixel's Skyblock Profiles system

[sterile hinge]

I mean you can tell the server whatever you want, but you'll most likely want to do that on a proxy so the servers only get the data provided by you

[lyric gyro]

You have to use a bunch of nasty reflection stuff if you want to change the uuid

but yeah it is possible, just really really hacky haha

You'd have to access the uuid field in the player object using reflection, then modify it to whatever, save the original uuid somewhere and restore it on player quit

Then restore whatever their last fake uuid was on join.

[stuck canopy]

ohh thanks for the info

[tired olive]

why would u need to change a player's uuid for profiles?

[stuck canopy]

coz I want to separate player's stats for each of the profiles

[merry knoll]

how does uuid interfere with that anyway?

keep the uuid as primary key

and add as many profiles as you want under it

[stuck canopy]

I want to make it work with other plugins and I want other plugins to think that its a new player when they create a new profile

[merry knoll]

ah, those other plugins arent yours i assume?

[stuck canopy]

yea

they depends on uuid

[merry knoll]

you have to do this #development message (not as hacky as claimed honestly)

but you would need to do it on prelogin most likely

most plugins load on player join

[rare charm]

ItemStack item = new ItemStack(Material.INK_SACK, DyeColor.LIME);

How do i fix that?

[lyric gyro]

brother, if changing the uuid of a player is not hacky I don't know what is xD

maybe I'll make a dummy plugin to see

[lyric gyro]

This isn't a valid constructor

Also its INK_SAC without the k

Ink sacs don't have any 'DyeColor' data on them, they're just regular items

[rare charm]

no

then it wont work

[rare charm]

and how do i get any dye then

im making a gui and wanna have lime dye innit

but lime dye isnt in 1.8.8

[lyric gyro]

oh, 1.8.8

Yeah, can't help with that sorry lol

but if an item doesn't exist in the version then you can't add it?

[rare charm]

no

it exists

but not with MATERIAL.blah

[lyric gyro]

yeah well you figure that out. Hard to get any support for a 7 year old version

[rare charm]

sagde

xd

[merry knoll]

its damage values usually

for colors of items

[merry knoll]

changing uuid itself isnt that hacky, but they probably need to register new players to the internal map to make it work

thats gonna be a bit more messy

[rare charm]

that makes 0 sense but ok...

xd

[merry knoll]

thats 1.8 for ya

[proud pebble]

you wouldnt change the player's uuid for it

and you shouldnt try

because overall changing the player's uuid is a bad idea

[merry knoll]

no, for what they want to do its necessary

they want to create fake users for players to use

and that can be used by any external plugin

[merry knoll]

this is 100% true, but eh

[dusky harness]

they just said that they want to recreate hypixel skyblock plugin
but if it's not their plugin, and it's not open source

[merry knoll]

hypixel can do it since they just use their own plugins

[dense drift]

I don't think anybody bothers to change player's UUID

[merry knoll]

yeah, its just not needed in your own ecosystem

dont see how they would create fake profiles in other plugins without changing name + uuid though

[proud pebble]

arent they better off just patching the other plugins, if its not public then just using something else that is or something like that?

or just scrap multiple profiles

[merry knoll]

if its public

doubt its possible

cant go around changing all plugins

[proud pebble]

well really its the only way

[hoary scarab]

new ItemStack(Material.INK_SACK, <AMOUNT>, <DURABILITY>)
Change durability to the data for lime.
If you have essentials hold lime dye and type /itemdb

[proud pebble]

its probably easier to just scrap the profiles idea since its probably unlikely people will actually try to use them or use them enough to be worth dealing with

I talk about spigot and not PaperMC

or in this case Waterfall

[dense drift]

that is a bungee class

[somber gale]

And? Still not Spigot... Otherwise would I not mention ProtocolLib here

[dusky harness]

Hostname or IP, e.g. localhost or 127.0.0.1, that was used to connect. The Notchian server does not use this information. Note that SRV records are a simple redirect, e.g. if _minecraft._tcp.example.com points to mc.example.org, users connecting to example.com will provide example.org as server address in addition to connecting to it.

do you think this would fit?

if so, it's handshaking serverbound (PacketType.Handshaking.Client.SetProtocol) and ```java
packetContainer.getStrings().read(0)

[dense drift]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerLoginEvent.html#getRealAddress()
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerLoginEvent.html#getHostname

[dusky harness]

you can also experiment with that, I doubt it's only accessible via packet

[somber gale]

Downside of these are the fact that they are only on join, while I need during ping.
The structure you mentioned doesn't seem to fit... It's probably getServerPings, but I'm not to sure about that.

[dense drift]

Ah you said ping

I mean, there's ServerListPingEvent

[somber gale]

Only has getAddress which is the player's address

[dusky harness]

why doesn't it seem to fit?

users connecting to example.com will provide example.org as server address in addition to connecting to it.

[proud pebble]

so when the player pings the server, you want to get the ms of the ping?

[somber gale]

I found a solution.

[proud pebble]

solution being?

[somber gale]

This one during a onPacketReceiving.
Was a bit confused as IntelliJ for some reason didn't suggest getStrings() and thought it was a bad example

[dusky harness]

oh
but does it compile?

[somber gale]

Yes. It suggested it afterwards

So maybe bad caching/indexing or smth

[dusky harness]

ah alr, intellij being weird 🥲

[hoary scarab]

So I asked before but here is the code that I wanted to put in a switch instead of multiple if's
illegal argument wouldn't help because I'm checking multiple different object instances not instances implementing the same object. I could be wrong though.

public Tag getTagFromObject(Object obj) {

[dense drift]

and the question is? 🥁

[hoary scarab]

How can I make use of switch or clean it up because I don't like the amount of if statements

[dusky harness]

maybe could use Class and switch that

[hoary scarab]

🙏

[dusky harness]

although not sure if that'll work because of unboxing and stuff

since idk if a byte is a java.lang.Byte

[sterile hinge]

you can't use Class in switches

[dusky harness]

you can't?

[merry knoll]

you got spoiled by when

[dusky harness]

🥲

wait but seriously

can you not compare Classes?

[hoary scarab]

So close... Cannot switch on a value of type Class<capture#1-of ? extends Object>. Only convertible int values, strings or enum variables are permitted

[merry knoll]

is the java version of it in production yet*

[dusky harness]

WHAT?!

[merry knoll]

yep

[dusky harness]

You can't compare using #equals on any object?????????

[edgy lintel]

https://tenor.com/view/sad-cement-seal-java-programming-gif-24524699

[dusky harness]

what switch is this?!?!!?!

[sterile hinge]

lol

switch never had anything to do with equals

[hoary scarab]

switch(obj.getClass()) {
case String:
    return StringTag.valueOf((String) obj);
}

[edgy lintel]

dear lord please save all the ignorant souls here they all have been forced to use java
please save all the cute people here, for your eternal kingdom will be glorified

[dusky harness]

case String.class I'd guess

BUT ITS NOT A THING IN JAVA

So

[merry knoll]

i think its a thing

[dusky harness]

try case String.class:

[merry knoll]

just not in production yet

[dusky harness]

Oh

[sterile hinge]

Java switches are mostly what came from C/C++

[dusky harness]

then nevermind

[graceful hedge]

Dont you have switch with pattern matching or whatever its called

[hoary scarab]

Thats not where the error is the error is on switch(obj.getClass()) {

[sterile hinge]

they are way more efficient than weird equals checks, but limited

[merry knoll]

yeah its been drafted in java 17

[edgy lintel]

The expression used in a switch statement must have an integral or enumerated type, or be of a class type in which the class has a single conversion function to an integral or enumerated type.

[merry knoll]

but its not in yet

[hoary scarab]

Well I could switch on class names but IDK felt like that wouldn't be as efficient.

[sterile hinge]

just use a map with functions as values

[hoary scarab]

?

[merry knoll]

apparently current solution is to create an enum

with classes in it

and switch over the enum

[edgy lintel]

use some custom enum class with their appropriate functions
enum.valueOf(obj.getClass().getName()).returnTag();

[dusky harness]

fun Any.getTag(): Tag? = when (this) {
    is String -> StringTag.valueOf(this)
    is Int -> IntTag.valueOf(this)
    is IntArray -> IntArrayTag(this)
    is Double -> DoubleTag.valueOf(this)
    is Float -> FloatTag.valueOf(this)
    is Long -> LongTag.valueOf(this)
    is LongArray -> LongArrayTag(this)
    is Byte -> ByteTag.valueOf(this)
    is ByteArray -> ByteArrayTag(this)
    else -> null
}
```cmon, java 😭

[graceful hedge]

Map<Class<?>,SomeFunctionThingy> (might wanna have an Identity hm)

[hoary scarab]

That might work. I'll test that out when I get back

[merry knoll]

yeah, this is what i used to do

[edgy lintel]

this is even better than enum

[merry knoll]

Map<Class,Handler>

[sterile hinge]

Map<Class<?>, Function<Object, Tag>> map = ...;
return map.get(obj.getClass()).apply(obj);

[edgy lintel]

eclipse: Generic types need to be wrapped with type arguments

imagine java

[merry knoll]

https://stackoverflow.com/questions/29570767/switch-over-type-in-java couple of solutions on here

[sterile hinge]

implementing something like that into the existing switch functionality is just a bit harder than implementing it from scratch :p

[dusky harness]

true

[edgy lintel]

false

[dusky harness]

but i mean the any object part

they should add

and the is

although in java's case it'd be instanceof

[merry knoll]

again, its already being drafted apparently

[dusky harness]

👍

thats nice

[merry knoll]

soon tm that is

[dusky harness]

lol

[edgy lintel]

not good

[dusky harness]

™️

[edgy lintel]

https://tenor.com/view/sad-cement-seal-java-programming-gif-24524699

[merry knoll]

i mean i prefer java honestly

[sterile hinge]

they do with pattern matching, but it's not ready yet

[merry knoll]

but coroutines kinda spoiled me on kotlin

[edgy lintel]

dude im beginning to hate on java with all those tedious typings

i have like 130 wpm but its still too slow for completing work

[dense drift]

java is known for its verbosity

[dusky harness]

🤢

[dense drift]

but that doesn't mean is bad

[edgy lintel]

man i would rather do assembly this way

[dusky harness]

Kotlin can also be verbose if you want

[merry knoll]

i mean github copilot handles most

[dusky harness]

but java forces it

[dense drift]

var is perfect

[dusky harness]

val 😌

[edgy lintel]

auto

[dusky harness]

Java isn't bad, it just can be better

[sterile hinge]

lol what about using an IDE?

[edgy lintel]

im on eclipse man
im about to use notepad++ for java later
Eclipse sucks

[merry knoll]

why would you use eclipse over intellij even

[edgy lintel]

man i will just code on paper

intellij too heavyweight for my potato pc

[sterile hinge]

sounds like a you problem

[edgy lintel]

its a me problem indeed

[merry knoll]

its only heavy on first run i feel like

[high edge]

Man seriously hating a language cause he decided to use a shitty ide kek

[merry knoll]

once its done indexing, it barely uses much

[high edge]

Mate I was running IJ perfectly fine on my old 32bit pc with 4gb of ram

[edgy lintel]

oh is that, i will give it a try lol

[high edge]

You have no excuse

[edgy lintel]

i have intel graphics and i3

[dusky harness]

if you do

download jetbrains toolbox first

[edgy lintel]

on my laptop

[merry knoll]

its using 700 mbs of ram on a big project being open currently

[high edge]

I had an i3 2nd gen I believe

[edgy lintel]

wtf

[dusky harness]

easier to manage JB apps
and also get ultimate if you're a student :))
and github copilot if you're a student :))

[high edge]

So you probably already have something better

[edgy lintel]

oh alr thx for the tip noted

isnt ultimate like paid?

[high edge]

If you're a student no

[merry knoll]

if you are a student

you can get all their products for free

#dev-general tho yes

[wheat carbon]

my ij uses 2.1gb with docdex opened

what is this 700mb magic

wait no ij says 395MB

[edgy lintel]

bro has worked since last life in parallel universe

[dusky harness]

my ij memory meter thing is always diff from task manager

¯_(ツ)_/¯

[high edge]

Mine normally uses like 1gb

[dense drift]

Smh pig

[spiral prairie]

Mine normally uses like 4

[dusky harness]

ah great, just opened it and the first thing I see in task manager is IJ using 2.6gb of memory

well I'll let it index first

[lost flower]

when is deluxetags getting 1.19 updated

[wheat carbon]

does it need an update

[spiral prairie]

3120 a.d.

[broken elbow]

it works just fine on 1.19

[lost flower]

well im using it on 1.19 with the new hex color shits, but when I type in chat the color all messed up

[dusky harness]

Finally indexed, only one window of intellij 🤔

[merry knoll]

Although this could be a factor as to why (38 plugins)

[merry knoll]

[dusky harness]

but after that now it's sitting at an exact 3,843.1mb

not even moving by 0.1

¯_(ツ)_/¯

[dusky harness]

#spigot-linking

prob

[merry knoll]

its peaking at 2.5 gigs for me rn after i cloned a repo

ugh. deluxetags. not deluxechat

[dusky harness]

oh mb

can't read

My average day

IJ takes around 6GB

[merry knoll]

Oh a lot of memory is nice

I've only got 16gb

☹️

[graceful hedge]

Hehe

[broken elbow]

omg

its conclure

[pulsar ferry]

If I only had 16 i'd die

[graceful hedge]

omg its blitz

[graceful hedge]

So cursed

[broken elbow]

hi conclure

[pulsar ferry]

Normally I need to be running 1 to 2 servers on IJ and have 3 mc opened at the same time

[graceful hedge]

hi blitz

[dusky harness]

thought it was a lot until I realized that my pc uses 60% memory on idle 💀

[wheat carbon]

windows user

[broken elbow]

I am dying. Fortunately is better than the 8 gb ddr3 I used to have. xD

[merry knoll]

ah, i just use a seperate mini server for testing

[pulsar ferry]

I love running it on IJ, makes debugging so much easier

[merry knoll]

yeah agreed, it would be pain for me if stuff started to freeze

and i got the server laying around so

[broken elbow]

my problem with running it in IJ, is that I have to set up the build configuration thingy for every project

[wheat carbon]

matt do you use hotswapping?

write something to do it for you then blitz

[broken elbow]

holy shit. 22% with discord open here! and a few other small hings like flameshot that don't really matter

[broken elbow]

I'm not that smart. Well maybe I'm just lazy

[pulsar ferry]

Unfortunately hotswap wouldn't work, too many things in the server like microservices running on docker containers though the minigames don't last that long to be needed

[high edge]

19% with discord and chrome opened, and I have 32gbs 💀

[queen plank]

When is the BlockExplodeEvent called? I get no output despite exploding blocks with both creepers and TNT. The event is registered properly so that is not the problem

The docs just says Called when a block explodes but it isn't called?

[dusky harness]

when a block, such as a bed explodes

EntityExplodeEvent are for entities such as creepers and tnt

oh, 30 minutes late

¯_(ツ)_/¯

[queen plank]

It is fine lol. But I explode blocks WITH the TNT/Creeper, which is why I am confused

[dusky harness]

it's only from the explosion source

[queen plank]

I know the TNT/Creeper won't trigger it, I just assumed that the dirt blocks or whatever would trigger it

[dusky harness]

so if the source is a block, then it will call that event

[queen plank]

Ohhh

That makes sense, thank you

[sterile hinge]

the dirt block doesn't explode itself, it's just affected by the explosion

[lyric gyro]

I'll explode you yourself

[queen plank]

Can anyone explain this?

System.out.println("Changed mat to " + material);
c.setType(material);
System.out.println(c.getType());

[21:00:58] [Server thread/INFO]: Changed mat to GRASS_BLOCK
[21:00:58] [Server thread/INFO]: VOID_AIR

There is no one in the world atm is that why? Am I maybe cancelling some event?

[sterile hinge]

what is c? was it VOID_AIR before?

[queen plank]

c is a block, sry

And yes it was

[sterile hinge]

is the block outside of the world height?

because VOID_AIR shouldn't appear otherwise normally

[queen plank]

ofmg...

I'm so dumb

It is

Thank you lol

[sterile hinge]

happy to help :p

[worn jasper]

Uhm If I have a class and I make it serializable, and lets say I create an object, serialize it into base64 and store it in a file

and lets assume that class, has a constructor with 3 params.

But now I want to add a 4th, how could I do that without causing issues?

how can I migrate it.

Cause data was serialized and stored when the class had 3 params and now it has 4

any ideas?

or well, to spice things up, it has a new param and one of the other params changed type.

[lyric gyro]

it entirely depends on what you're using for the (de)serialisation process

[tacit belfry]

Is it cursed to use java 18 to code a 1.8.9 spigot plugin?

[lyric gyro]

does 1.8 even work with java 18?

[tacit belfry]

I found forum threads saying that it did, and apparently hypixel just updated their server to use Java 17 whilst using 1.8

[lyric gyro]

hypixel is no point of comparison

they have an extremely modified and custom environment

[tacit belfry]

I mean i understand that, but I was wondering because I already have java 18 and its a pain to mess with two different java versions at once

[worn jasper]

public static Object fromString(String s) {
        Object o = null;
        try {
            byte[] data = Base64.getDecoder().decode(s);
            ObjectInputStream ois = new ObjectInputStream(
                    new ByteArrayInputStream(data));
            o = ois.readObject();
            ois.close();
        }
        catch(Exception e)
        {
            System.out.println(e);
        }
        return o;
    }```

if ya wanna go specific

[lyric gyro]

oh yikes, regular java serialisation

[worn jasper]

ye

[lyric gyro]

is this running in a controlled environment / somewhere you have control of? Or is this in some public plugin many servers use?

[worn jasper]

private plugin

so yes, controlled env.

[lyric gyro]

Okay yeah uh because java serialisation isn't exactly meant for storage lol, I strongly, really strongly suggest you migrate this to a proper storage system, either SQL or flat-file (json etc)
But to answer your question, changes in the constructor won't affect that because ObjectOutputStream does not call the constructor; the concern here is added/removed/renamed fields

[worn jasper]

well lets say that also got changed...

what could I do?

[lyric gyro]

cry

[worn jasper]

😭

fair enough

so, if I add fields it will also cause issues right?

[lyric gyro]

you could migrate to a proper storage system that allows you to perform versioned migration or smth before changing the stuff you want to change

but that is a lot of effort with much caution

[tacit belfry]

I have an isOnCooldown() method and it returns a double, which is the current cooldown. I was wondering if it would be better to split it up into two methods, boolean isOnCooldown() and int getCooldown()

[merry knoll]

i would say yes

[lyric gyro]

isOnCooldown doesn't sound like something that would return a number, lol

[icy shadow]

unless you're using C

[worn jasper]

It’s something I didn’t think about at the time I did the plugin, whenever I recode it, I surely will do this

[lyric gyro]

wish you luck, lol

hello how could i get custom hex color in 1.18.2

i tried Chatcolor.of() but is it working for 1.18.2 too ?

[lyric gyro]

should be

net.md_5.bungee.api.ChatColor.of()

[edgy lintel]

hey guys what is usually an invalid bukkit task id

i assume it is something like -1

nvm ignore figured it out

Anyone else having issues with spigot 1.19.1 and maven?

[sterile hinge]

Where do you get the remapped jar from?

[hoary scarab]

I forgot to build it 🤦

[sterile hinge]

Well

[hoary scarab]

Works lol

And.... it wasn't needed because the package names haven't changed 🤦

[hoary scarab]

I thought setting an armorstand as a marker was suppose to stop it from turning the name dark when inside blocks?

[pulsar ferry]

Set it on fire to fix it

[hoary scarab]

If I set to max will it go out eventually?

[dense drift]

2.7b seconds are 85 years

[hoary scarab]

So yes. xD

[dense drift]

yea.. yes

[hoary scarab]

Was hoping if it was at max it wouldn't tick.

[pulsar ferry]

It's in ticks so wouldn't it be 3.4 years?

[dense drift]

ah, ticks

[hoary scarab]

Didn't fix it.

[pulsar ferry]

You sure? How are you doing it?

[hoary scarab]

nmsStand.setRemainingFireTicks(Integer.MAX_VALUE);

[pulsar ferry]

Try setFireTick

[hoary scarab]

doesn't exist for ArmorStand

Its an NMS entity not bukkit.

[pulsar ferry]

Ah, no clue then

[hoary scarab]

nmsStand.displayFireAnimation(); didn't work either.

[dense drift]

https://nms.screamingsandals.org/1.19/net/minecraft/world/entity/Entity.html setSecondsOnFire(int arg0) maybe

[hoary scarab]

Thats how long its been on fire.

Also if I move the armorstand into water it causes the splash particles... Whats the point of setMarker(boolean) again?

[dense drift]

smaller hitbox and probably other stuff

[hoary scarab]

It removes the hitbox, that one I know lol

[dense drift]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/entity/CraftEntity.java#576-579 so it should be setRemainingFireTicks

[hoary scarab]

I did that. Doesn't work

nmsStand.setRemainingFireTicks(Integer.MAX_VALUE);
nmsStand.displayFireAnimation();
nmsStand.hasVisualFire = true;
nmsStand.wasOnFire = true;

[dense drift]

try with only that specific method

[hoary scarab]

I have

With all of those lol

Could it be a 1.19.1 issue?

[quasi wigeon]

The protocollib PacketType.Play.Server.CHAT seems to not be called on 1.19, has something be changed?

[lyric gyro]

lots of things have

[quasi wigeon]

what packet should I listen now for outgoing chat packets?

[lyric gyro]

It depends

idk the plib names, idek if it's updated yes but now there's ClientboundSystemChatPacket and ClientboundPlayerChatPacket, the first one are system messages, like command feedback and those from plugins, the latter are messages sent by players

Uhhh

okay I see nothing

[worn jasper]

don't u dare checking logs.

[broken elbow]

haha already did

[queen plank]

What is the pattern for <RandomStringUsingAnyChars>? It has to start and end with <>

I tried smth like <(.)> but it doesn't match what I want it to

[dense drift]

<[^>]+> this should work, [^>] means "anything except this"

[icy shadow]

<(.+)> works too

i dont think you need the ^>

[dense drift]

it stops at the last >, not first

[icy shadow]

ah yeah

so depends what you want really

likely gabys one

[queen plank]

This Matcher m = Pattern.compile("<[^>]+>").matcher("<Hello> Hi"); gives me No match available

[dense drift]

yeah, if it is only alphanumeric characters, you can just use \w+

do you use m#find() ?

[queen plank]

It isn't I use @ n stuff in the strings

Ohh

No I did not

I just thought that was a method to check if there was a match or not

Didn't read the docs properly

Sry lol. Thanks 🙂

[dense drift]

nah, Pattern#matcher create a Matcher, you have to use #find() to see if it matches and to go trough the entire string while (m.find())

[queen plank]

Yeah, got it! Thank you!

I realised another thing lol. Is it possible to get a pattern once the <> is fully closes. Idk how to explain it, but I need to get B:<C> from a string like A:<B:<C>>. Is this possible using patterns or no?

[edgy lintel]

Pattern.compile("\\<inbetween\\>");

try sth like this

[icy shadow]

I think if you have nested <> then that's pushing the limits of context-free grammars

Or the limits of regexes at least, they can't be recursively defined

[queen plank]

K lol, I guess I'll make a function for it

[icy shadow]

Sorry not context-free

[dusky harness]

I think the only way to use regex with this is to just have a long regex

for each one inside

(each one inside possible)

[icy shadow]

For arbitrarily deep nesting it's impossible dkim

[queen plank]

This isn't really an option as the inside can be literally whatever. Guess no regexes :V

[dusky harness]

wdym

[icy shadow]

the inside doesn't matter

Maybe I'm misunderstanding what you're describing

[dusky harness]

I mean anyways you can't have an infinite amount or as you said recursively defined so I'd just make my own method

[queen plank]

Yup, guess I'll have to. Thanks tho :>

[icy shadow]

Let's say you have a list syntax [1, 2, 3] and you want to parse lists of lists [[1], 2, [[3], [4]]]
This is impossible to parse reliably with a regex because it would involve a recursive definition

[dusky harness]

yes but it probably is possible to make a group in a group etc to sort of replicate it

Sort of

although not infinitely

[icy shadow]

not infinitely yeah

And it would be very difficult to do even with 2 levels of nesting

[dusky harness]

well for example

\w(:<\w(:<\w(:<\w(:<\w(:<\w(:<\w(:<\w(:<\w>|)>|)>|)>|)>|)>|)>|)>|)
```this works (just using letters)

for 9 letters

(I'd still make my own method but I'm just showing an example)

[queen plank]

It literally could not have been easier :>```java
private static String getBonus(String string) {
int index = string.indexOf('<');
if (index == -1)
return null;
int open = 1;
string = string.substring(index + 1);
for (int i = 0; i < string.length(); i++) {
if (string.charAt(i) == '<')
open++;
else if (string.charAt(i) == '>')
open--;
if (open == 0)
return string.substring(index, i);
}
return null;
}

[sterile hinge]

yeah regular expressions cannot validate bracketing

also regex is ugly

[broken elbow]

this will force parity tho<<>> . Stuff like this <<> won't work. not sure if that's something you want.

[queen plank]

That is what I want 🙂

Otherwise the string is faulty and it should throw an error (return null)

[broken elbow]

alright. just making sure

I didn't read the whole conversation

[queen plank]

I didn't mention it before. But thanks for mentioning it :>

Is there any way to retrieve the texture of a head with a texture? (aka, get the head in my hand and return it's texture)

[dense drift]

        val owner = NBTItem(this).getCompound("SkullOwner") ?: return ""
        return owner.getCompound("Properties").getCompoundList("textures")[0].getString("Value")```

basically the texture base64 string is located at SkullOwner.Properties.textures[0].Value
