thank you

Hey I got a protocol Lib question, I currently have this for sending a "fake item" packet saying that the user has x mask on but I need it to update all the masks for the player that just joined the server

@Override
    public void onPacketSending(PacketEvent event) {
        Player player = event.getPlayer();
        int slot = event.getPacket().getIntegers().readSafely(1);

        if (slot != 4)
            return;

        PacketContainer equipmentPacket = new PacketContainer(PacketType.Play.Server.ENTITY_EQUIPMENT);
        ItemStack item = equipmentPacket.getItemModifier().readSafely(0);
        System.out.println(player);
        if (item == null || item.getType() == Material.AIR)
            return;

        NBTItem nbtItem = new NBTItem(item);

        if (!nbtItem.getBoolean(NBTConsts.GLITCH_ITEM))
            return;
        String type = MaskUtils.getMaskType(item);
        int level = MaskUtils.getMaskLevel(item);
        Masks.Mask mask = MaskUtils.get().getMask(type, level);

        if (mask == null)
            return;

        equipmentPacket.getIntegers().write(0, player.getEntityId()).write(1, 4);

        equipmentPacket.getItemModifier().write(0, mask.getMaskItem());
        event.setCancelled(true);

        // Forward the modified packet to all online players except the sender
        for (Player targetPlayer : Bukkit.getServer().getOnlinePlayers()) {
            if (!targetPlayer.equals(player)) {
                ProtocolLibrary.getProtocolManager().sendServerPacket(targetPlayer, equipmentPacket);
            }
        }

    }

brub

[split gull]

thats for big pieces of code right? if its small it should be ok

[tender shard]

change "spigot-api" to spigot with classifier "remapped-mojang". but as mentioned above, you don't need to do that, you already got the CBD to get a context from

[static ingot]

yes

[split gull]

alr

[tender shard]

just another self promotion since you already use my CBD lib, maybe you also find this useful:

?morepdc

[undone axle]

You can create custom persistent data types on your own, or use one of the many libraries available which have implemented those which match your needs. Learn about more persistent data types here: https://www.spigotmc.org/threads/more-persistent-data-types-collections-maps-and-arrays-for-pdc.520677/

[tender shard]

it allows to use maps, arrays, collections etc, e.g. to save a Map<EntityType,List<ItemStack>> and other fancy stuff in PDC

[split gull]

yeah i'll be using that soon

im implementing all the standard stuff first

then i'll add all the custom ones

ty for making these ❤️

[small holly]

currently I am considering just using an PlayerJoinEvent but if you got lots of players online thats a lot to do

[split gull]

actually, this wont work, what i mean is creating a standalone PDC, without having to use another's context

well it would work, but it's not what im looking for

[tender shard]

then you indeed need the craftbukkit classes

[split gull]

alr

[tender shard]

like this ^

you can cache the registry and context and reuse it btw

Player#showParticle(...)

or sendParticle, idk

[split gull]

there's no spigot-api in what i've just sent

or did i miss it

with classifier i assume you mean <remappedClassifierName>remapped-obf</remappedClassifierName>

[tender shard]

noo

        <dependency>
            <groupId>org.spigotmc</groupId>
            <artifactId>spigot</artifactId>
            <version>1.20.1-R0.1-SNAPSHOT</version>
            <scope>provided</scope>
            <classifier>remapped-mojang</classifier>
        </dependency>

[split gull]

ohh

ty ill try it

[tender shard]

did you read the blog post I linked earlier? you need to run buildtools for this to work java -jar buildtools.jar --rev 1.20.1 --remapped

otherwise maven won't find spigot

well check the javadocs

[split gull]

yeah my bad, i usually dont understand these commands

[tender shard]

you download buildtools, and then run it with the --remapped parameter

?bt

[undone axle]

https://www.spigotmc.org/wiki/buildtools/

[tender shard]

https://www.spigotmc.org/wiki/buildtools/#running-buildtools

[split gull]

do build tools work across multiple versions?

like does 1.19.4 work with upper and other 1.19 releases?

[tender shard]

buildtools works for every 1.8+ version, but your code will be version dependent because the craftbukkit classes have the version in the package name

e.g. the CraftPersistentDataTypeRegistry on 1.20 is in package org.bukkit.craftbukkit.v1_20_R1.persistence

[split gull]

well thats an issue for me

i see

[tender shard]

then you gotta use reflection or a multi module project

[split gull]

oh god fancy words

is any of what you've mentioned going to require me to update the plugin whenever a new minecraft version drops for it to work on it?

[quaint mantle]

yes

sometimes

[split gull]

then it's not worth doing, i dont want it to be version dependent

[quaint mantle]

well

not necessarily version dependant its just for certain updates the class may change its signature or functionality

[split gull]

for starters, what does creating a new pdc with a context do? whats the relationship between this new pdc and the context?

[split gull]

bruh

[quaint mantle]

you may be able to hope that each new update doesnt change any of that

reflection is your friend there

[tender shard]

        try {
            String packageName = Bukkit.getServer().getClass().getPackage().getName(); // Will be org.bukkit.craftbukkit.v1_20_R1
            Class<?> craftPersistentDataTypeRegistryClass = Class.forName(packageName + ".persistence.CraftPersistentDataTypeRegistry");
            Class<?> craftPersistentDataAdapterContextClass = Class.forName(packageName + ".persistence.CraftPersistentDataAdapterContext");
            Object registry = craftPersistentDataTypeRegistryClass.getConstructor().newInstance();
            PersistentDataAdapterContext context = (PersistentDataAdapterContext) craftPersistentDataAdapterContextClass.getConstructor(registry.getClass()).newInstance(registry);
            PersistentDataContainer myPdc = context.newPersistentDataContainer();
        } catch (ReflectiveOperationException ex) {
            throw new RuntimeException(ex);
        }

this works in all versions

[split gull]

oh damn

[tender shard]

you should cache the "context" object somewhere

[split gull]

yeye

[quaint mantle]

wtf is context

[split gull]

trust me i have no clue

it's just something that exists

[quaint mantle]

whats all in this 1.20 update

[split gull]

it's been a thing

[quaint mantle]

oh

[tender shard]

eg like this

public class MyPlugin extends JavaPlugin {
    private static final PersistentDataAdapterContext dummyContext;

    static {
        try {
            String packageName = Bukkit.getServer().getClass().getPackage().getName(); // Will be org.bukkit.craftbukkit.v1_20_R1
            Class<?> craftPersistentDataTypeRegistryClass = Class.forName(packageName + ".persistence.CraftPersistentDataTypeRegistry");
            Class<?> craftPersistentDataAdapterContextClass = Class.forName(packageName + ".persistence.CraftPersistentDataAdapterContext");
            Object registry = craftPersistentDataTypeRegistryClass.getConstructor().newInstance();
            dummyContext = (PersistentDataAdapterContext) craftPersistentDataAdapterContextClass.getConstructor(registry.getClass()).newInstance(registry);
        } catch (ReflectiveOperationException ex) {
            throw new RuntimeException(ex);
        }
    }

}

[tender shard]

PersistentDataTypeAdapterContext, exists since 1.14.1

[quaint mantle]

ive never touched that shit and hopefully i never have to

didnt even know that existed and i thought i memorized the entire API at one point

[split gull]

the // Will be org.bukkit.craftbukkit.v1_20_R1 comment is just you assuming im using 1.20 right?

[tender shard]

no

[split gull]

oh

[tender shard]

it will be v1_19_R3 in 1.19.4 for example

[split gull]

ohhh alright

perfect, thank you very much

[tender shard]

Bukkit.getServer() returns the interface "Server" but getClass() on the actual object returns its implementation class

hence you will always get the correct package name, no matter which version

[split gull]

you're a savior 🙏

[tender shard]

np

it's like Bukkit.getPlayer(...) seems to return a Player, but it's actually a org.bukkit.craftbukkit.<version>.entity.CraftPlayer or sth, which just implements Player

[split gull]

what about this btw?

[worldly ingot]

Just being able to create an instance of it as an interface is all

The implementation isn't exposed to Bukkit so you can't create instances of it

But really it's not doing much under the hood aside from passing through the type registry, https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/persistence/CraftPersistentDataAdapterContext.java

[split gull]

oh alright

[tender shard]

i wonder why all classes (Entity, ChunkAccess, etc) have their own CraftPersistentDataTypeRegistry, why don't they all use the same instance?

choco, any idea?

[shut sphinx]

hey i hate to have to ask this here,
i was wondering how i can detect which chunks are taking the longest to tick

[quaint mantle]

How can I convert a spigot gradient to a mojang gradient when I just use a nms Component.literal it becomes this §x§3§e§4§2§f§6
(&#3e42f6 is the gradient)

[worldly ingot]

¯_(ツ)_/¯

I didn't implement it

[tender shard]

damn this class is getting more and more ugly in every commit

[shut sphinx]

oh, dude

why is it so light?

[glad prawn]

💀

[quaint mantle]

💀

[quaint mantle]

anyoe know

[tender shard]

huh is this really the correct form to mention constructors in javadocs? ClassName#ClassName() ?

[shut sphinx]

how would u go about detecting lag machines?

what methods have u guys come up with?

• looking for where players are during lag spikes and honing in on - those chunks?

• ruitine scan of all chunks tick speeds to see which ones are taking the longest to tick?

• something else?

interested to hear ur guys thoughts as fellow developers

[small holly]

Anyone able to help me with some protocolLib stuff?

PacketUtils class https://sourceb.in/0vLrfGkAAs
Method that calls the setHelmet method https://sourceb.in/weVuaNfXVr
Issue: Packets only get sent sometimes but unsure if thats just a stroke of luck of something up with the code
Ideal outcome: Player 1 puts on a helmet with a mask "bound" to it and all players excluding player 1 see the mask instead of the helmet

its so annoying because It can work one second then bam not work again

[manic delta]

I want to make a personal plugin to send commands to the minecraft servers of my network, separately, I already have the logic and everything, I will use mysql for it, but my problem is that "I don't know how to optimize it", there are 200 users at the same time by server but with the code as such it ends up exploiting the server, can someone help me? I tried to use Scheduler Programming but I don't see any change

[flint coyote]

Why do the commands depend on the amount of players? Is it the same command times each player?

[manic delta]

To who u are talking

[flint coyote]

you

[manic delta]

The data query will be done every 5 minutes, but when the players enter the server starts to die, regardless of whether I'm asking for data or not

I mean, just by connecting it, everything starts to explode.

[flint coyote]

Are you doing your query on the main thread?

[quaint mantle]

How can I convert a spigot gradient to a mojang gradient when I just use a nms Component.literal it becomes this §x§3§e§4§2§f§6
(&#3e42f6 is the gradient)

[manic delta]

Probably, I'm not really sure, it's the first time I've done this, but in theory based on what I did, I made a thread with scheduler programming to do it.

[flint coyote]

Show me the scheduler. It has to mention "async"

[manic delta]

sure 1sec

[manic delta]

public static void insertInv(StaffInventorySQL staffInventorySQL) throws SQLException {
        BukkitScheduler scheduler = Bukkit.getScheduler();
        scheduler.runTaskAsynchronously(Main.getPlugin(), () -> {
            try {
                PreparedStatement statement = Main.getPlugin().getConnection().prepareStatement("INSERT INTO staff_" + getDatabaseType() + "(uuid, inventory, armor, fetched) VALUES (?, ?, ?, ?)");
                String inventory = Base64.itemStackArrayToBase64(staffInventorySQL.getInventory());
                String armor = Base64.itemStackArrayToBase64(staffInventorySQL.getArmor());
                statement.setString(1, staffInventorySQL.getUuid());
                statement.setString(2, inventory);
                statement.setString(3, armor);
                statement.setString(4, staffInventorySQL.getFetched());
                statement.executeUpdate();
                statement.close();
            } catch (SQLException e) {
                e.printStackTrace();
            }
        });

    }

I clarify that it is only an example and some tests lol

||and that he was not very sure how to use the schedule programming with this||

[flint coyote]

hmm "runTaskAsynchronously" looks alright

[manic delta]

BukkitScheduler scheduler = Bukkit.getScheduler();
        scheduler.runTaskAsynchronously(this, () -> {
            try {
                DatabaseManager manager = new DatabaseManager("", 3306, "s2", "ud", "+1");
                this.connection = manager.getConnection();
                manager.createTable();
            } catch (ClassNotFoundException e) {
                Chat.sendConsoleMessage("&a[DB] &cError to connect");
                e.printStackTrace();
            } catch (SQLException e) {
                Chat.sendConsoleMessage("&a[DB] &cError to create the main table");
                e.printStackTrace();
            }
        });

I have this on onEnable()

[flint coyote]

So you used it that way aswell? Since you said this is just an example. The asynchronous part is important

[manic delta]

yes

[flint coyote]

Well since the server is not dying after your plugin, what are you doing in the PlayerJoinEvent?

[manic delta]

nothing

[manic delta]

well its

[flint coyote]

Where do you execute your query?

[manic delta]

every five minutes

[flint coyote]

where

do you run it asynchronous aswell?

[manic delta]

At the moment I did not put it but it still crashes

just by loading the plugin

[flint coyote]

Oh so you load the plugin and even without players on the server it crashes again?

[manic delta]

sure

First it starts with very bad tps, then it gets worse

[flint coyote]

does this happen without you trying to connect to the db? E.g. commenting that part out?

[manic delta]

and finally it gives a thread error and explodes

[manic delta]

Nope

I will make the plugin again from 0 so I am open to suggestions

[flint coyote]

Are you 100% positive on that statement? It does look right to me. An asynchronous thread should never lock the main thread

[manic delta]

Yes

I'm going to redo the plugin so I'll be testing things anyway but I know what's going to happen

[flint coyote]

Well in that case you should check your crash dump for the line of your plugin that's causing the crash

Check if it's actually that part, too

[manic delta]

It's just that I tried that a long time ago and gave up, but I want to get back on it, I'm energized again 💪

[flint coyote]

Sounds cool. Can you

[manic delta]

I am making the table in the database and then I will make the plugin

[flint coyote]

?paste your crash dump?

[undone axle]

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

[manic delta]

i'll do it when i'm done

[flint coyote]

Sure, I just can't offer more help with your crash before I see it :)

[manic delta]

There is no more optimal way to use?
BukkitScheduler scheduler = Bukkit.getScheduler();
scheduler.runTaskAsynchronously(this, () -> {});

[manic delta]

yep is ok

[manic delta]

I mean I don't like to repeat it all the time

[flint coyote]

You can always create a function to have less copy&paste or work with CompletableFuture

[manic delta]

Uhm I don't know much about asynchronous stuff, I'm not sure how to do it

[flint coyote]

https://www.spigotmc.org/wiki/asynchronously-working-with-a-database/

[small holly]

been stuck on this for legit like 2 days now

[flint coyote]

well it's mostly about creating a function that does what you need and returns the object you wanna work with

[small holly]

Imma grab something to eat so if someone responds please ping

[quaint mantle]

How can I convert a spigot gradient to a mojang gradient when I just use a nms Component.literal it becomes this §x§3§e§4§2§f§6
(&#3e42f6 is the gradient)

[small holly]

Anyone?

[river oracle]

that's how its supposed to look

[quaint mantle]

but it doesnt display as a hex code

it only displays as the &6

[river oracle]

idk then you'll have to figure it out yourself, NMS isn't very well documented

you shouldn't ever really need to use mojang components anyways

[quaint mantle]

I'm sending a packet that requires a nms component.

[rapid gust]

I have a very strange issue, to begin with, my plugin cannot access some parts of the config file, but it can access others... however if i use /reload this completely fixes it?? Anyone have any idea what this could be? Thanks 🙂

[flint coyote]

Do you change those entries manually while the config is already loaded?

[rapid gust]

nope, at this point nothing has been changed at all

[flint coyote]

So you load the config, try to change values and it can't access them?

[manic delta]

i think i managed to do it

[rapid gust]

literally just saveDefaultConfig(); (in enable) and then plugin.getConfig().getBoolean("settings.debug") (which works) and then plugin.getConfig().getConfigurationSection("designs").getKeys(false); (Which does not work until after a /reload

[manic delta]

is ok for now

[flint coyote]

That sounds odd, can you send some code? And pls doublecheck that the config on the server is the same as the one in the jar.

[rapid gust]

even stranger?! after enabling spigot debug and rebooting its now working fine?!?

let me reboot a couple more times and see if it stays the same

[flint coyote]

/reload can cause weird issues. It works fine 95% of the time. If you have weird issues you should however always do a full reboot

[rapid gust]

yeah i have been rebooting, however /reload seems to fix the issue...

[flint coyote]

that should not be the case

[rapid gust]

exactly... thats whats confusing me so much lmao

one sec

the issue seems to be with this line (seprate class)

[flint coyote]

why do you call "getInstance()"? That's probably not an issue but plugin.getConfig() should work just fine

can you show me where you are calling the saveDefaultConfig()?

[rapid gust]

thats used to get the plugin from the main class

[rapid gust]

(Main)

[flint coyote]

and what's plugin?

[flint coyote]

inside the class you are calling it I mean

[rapid gust]

thats reffering to the main class

i had just renamed it to try something else and should have probably put it back before taking that ss lol. sorry about that

[flint coyote]

Is your main class named "plugin"? Because if "plugin" in your other class is already an instance there isn't really a reason to call getInstance

[flint coyote]

Anyways, that should not be the reason for your problem.
What does this line return when it fails? null?

or basically, is it a nullpointer because you call the getkeys?

[rapid gust]

null I believe, as it doesn't actually produce any errors, however when I then try to get the size (and use this in an rng - this is where the error was actually thrown as cant be 0) the size is 0

[flint coyote]

If you don't get an error it won't be null. Otherwise .getKeys would throw a NPE

its so annoying because It can work one second then bam not work again

[rapid gust]

if i remove getInstance()

[flint coyote]

Wait, plugin is a public static variable? Why?

Actually your function seems to be in a static context aswell. Maybe that's why your config is fucked up

You should never be in a static context unless you are calling some utility class

You can however create a static function in your main class that returns "this" and then do YourMainClass.getInstance().getConfig() ...

[eternal oxide]

You can;t actually return this in a static context. You have to set an instance variable and return that

[flint coyote]

oh, true. I guess I should go to bed some time soon

[eternal oxide]

🙂

[flint coyote]

already hit the 24 hour mark 😅

[eternal oxide]

I'm at the other end, not awake yet

[flint coyote]

Time flies when coding. Especially when it's not searching for annoying bugs for hours on end

Good morning btw

[eternal oxide]

Morning 🙂

[rain patio]

I'm trying to use a GUI to select a color and for some reason setCancelled(true) isn't working because I can pick up the item and put it in my inventory and when I reopen the gui the item is missing and I can just put it back like a player vault, can anyone help me? I've registered the listener and I don't know why its doing this

[rapid gust]

Thank you so much for your help, I managed to work it out I think... It seems it only happens if the config file has just been generated. Still not completely sure why it happens, might be a mistake in my code (likely) or could be a strange bug w spigot (less likely) edit: I think it matters where exactly in the load saveDefaultConfig(); is placed. I think it wasnt working as I had it too far down?

[shadow night]

Hey, I want to make some machinery like in tech mods. My idea is to add custom crafts that give renamed blocks which on placement write to the block pdc and start a timer that runs every tick for checks. But I thought of storing it and using config files or databases just feels wrong. What should I use, in your opinion?

[placid moss]

just change block nbt

and store the blocks on runtime in a list f some sort

or you can like lazy load them

[shadow night]

But if I restart the server, won't it all be gone?

[placid moss]

but you can just reload them using block nbt

because im pretty sure that is store inside the chunk?

or am i tripping

[shadow night]

Yeah

But do I like check every loaded chunk?

[placid moss]

thats probably the best way

[shadow night]

Ig

[placid moss]

in like some sort of chunk load event

[shadow night]

I'll do that that way then, thanks

Been stuck on this for almost 3 days now

[placid moss]

with that code wouldn't new players who join after the helmet is equipped not be able to see the helmet?

also players who disconnect and rejoin will not e able to see it

[small holly]

got something else for that

[placid moss]

oh ok

[small holly]

I tried with a packet listener but for some reason it sets the mask on all the other players

public class PacketListener extends PacketAdapter {



    public PacketListener(Plugin plugin, ListenerPriority listenerPriority, PacketType... types) {
        super(plugin, listenerPriority, types);
    }

    @Override
    public void onPacketSending(PacketEvent event) {
        Player player = event.getPlayer();
        int slot = event.getPacket().getIntegers().readSafely(1);

        if (slot != 4)
            return;

        ItemStack item = event.getPacket().getItemModifier().readSafely(0);
        if (item == null || item.getType() == Material.AIR)
            return;

        NBTItem nbtItem = new NBTItem(item);

        if (!nbtItem.getBoolean(NBTConsts.GLITCH_ITEM))
            return;

        if (!nbtItem.getBoolean(Consts.maskBound))
            return;
        String type = MaskUtils.getMaskType(item);
        int level = MaskUtils.getMaskLevel(item);
        Masks.Mask mask = MaskUtils.get().getMask(type, level);

        if (mask == null)
            return;

        PacketUtils.setHelmet(player, mask.getMaskItem());

    }
}

[placid moss]

your setHelmet method sets the helmet for some player, so if you are sending the equipment packet to all the other players, that will setHelmet on all the other players

[small holly]

so how would I do it then? Ive not touched protocol lib in like 4 years lol

[placid moss]

I guess you could store the player / helmet status in some sort of map and every time a player joins, you would loop through this map and send a packet that tells this new player all the helmets of the other players. For this, you would just do what you did up there with entity equipment packets, one for each player with a helmet.

[placid moss]

I am pretty sure the only way to do this is using PrepareItemCraftEvent and CraftItemEvent

and then manually do math

[small holly]

I am still having an issue where for some reason the sending of the packet wont work 90% of the time

[dire bluff]

Can u help me a bit with that

[small holly]

dont both just use Material not ItemStack?

[placid moss]

Yea just use ExactMaterial and then use PrepareItemCraftEvent to check if the slots have enough items, if so add the result to the result slot

And then on itemcraftevent simply subtract the right amounts from each slot

[placid moss]

Are you certain that the packet sending code is being called every time

i.e. its not the nbt checks for glitch item that are causing the issue

[small holly]

Yep added the System.out.println(player.getName() + " -> " + targetPlayer.getName()); gets sent every time

[placid moss]

Also istg that helmet is number 5

lemme check wiki.vg

[small holly]

I thought so too

but nope its in the armor slots

[placid moss]

🤔

ok anyways

[small holly]

1.8

[placid moss]

ah ic

[small holly]

no off hand

I love being stuck in 1.8 for this server ;-;

thankfully the cannon Jar dev is making a 1.20 version so we can finally do 1.20

[placid moss]

is this code running or is it just like a test

[small holly]

it runs but doesn't work as intended

[placid moss]

aren't the two code pieces colliding

one is changing the packet sent

and results in the packet being sent more

[small holly]

when I test the packet listener one I comment out the other one

[placid moss]

uhh

ok

[placid moss]

The equipment packet is sent to the viewer, so idk if this code makes sense

cuz its listening for the entity equipment packet

and then making it so that the player who is viewing the armor

gets the armor

[small holly]

ye that is what I was getting

[placid moss]

you should just use the interact listener

and then keep that code

and then just use a hashmap and send on join

because I don't see an issue with the code

if the packets only work like sometimes, is there like a pattern to when it does not work?

[dire bluff]

idk whaat to do i cant do it...

[timid hedge]

How do i import something from my other plugin to my plugin?

[placid moss]

add plugin as a dependency

so add as depend in plugin.yml

and then use either a) the api for the plugin if its available as a repo b) use the jar as a dependency

then you can just grab the plugin instance with Bukkit.getPluginManager.getPlugin(name)

[timid hedge]

I dont understand

[obsidian plinth]

with bedrock packs is it possible to replace some chars with imgs like java

[hollow beacon]

yo, is there a way to get the configurationSection.getKeys(false) in order of the actual config

[chrome beacon]

Why do you need it in the correct order?

[hollow beacon]

saves me an extra field to get the order I want

[chrome beacon]

It's a lot more work to get it in the right order

[hollow beacon]

aw

[brazen violet]

java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'EXITS spieler_sprache(uuid String, sprache string)' at line 1

need the code?

[chrome beacon]

EXITS

Typo ^

[shadow night]

how can I set the state of a furnace? Like, the amount of fuel it already used up from the total. I want to be able to control how long it burns and stuff

[brazen violet]

sorry can you explain first time with mysql xd

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Furnace.html

[shadow night]

thanks

[chrome beacon]

You probably want EXISTS

[brazen violet]

yes

[brazen violet]

thats what i want

"CREATE TABLE IF NOT EXITS spieler_sprache(uuid String, sprache string)";

[chrome beacon]

Yup

So fix the typo

[brazen violet]

and what is the typo

[chrome beacon]

._.

[chrome beacon]

.

[quaint mantle]

would pdc be the best way to make some blocks interactable, like a chest or sm shit to open a different gui

[chrome beacon]

PDC is a good way to identify your blocks

[quaint mantle]

so is that a yes or is there another better way

[placid moss]

plugin.yml has a section called depend

add the dependency name in the list

[chrome beacon]

That is a yes

[brazen violet]

okay thanks know i know the typo but i dont really know what to fix there...

[chrome beacon]

?

Use the right word?

[brazen violet]

and what is the right word

[chrome beacon]

.

[brazen violet]

OH

I WROTE IT WRONG WTF AM I BLIND

[brazen violet]

thanks mate

[glad prawn]

you're not blind, just bad eyes xd

[brazen violet]

true

java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ' sprache string)' at line 1

did i wrote something wrong again?

the S big or

[chrome beacon]

String isn't a valid type

Use varchar or text

[brazen violet]

what would be better

depends on what i do or

[chrome beacon]

With varchar you can define a max length

[brazen violet]

then i use text

[chrome beacon]

Sure

[brazen violet]

like this´?

String sql = "CREATE TABLE IF NOT EXISTS spieler_sprache(uuid String, sprache text)";

[chrome beacon]

Yeah

Does MariaDB have uuids though

Maybe not so make string text again

[brazen violet]

java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ' sprache text)' at line 1

something went wrong

[vivid cave]

Some questions about PrepareSmithingEvent

[chrome beacon]

.

Did you do that

[brazen violet]

so the uuid String to uuid text

[brazen violet]

yep that worked big thanks to you Olivio

[timid hedge]

Okay and what should i write here?

[placid moss]

the name of the plugin you are depending on:

depend:
- "Plugin1"
- "Plugin2"

[timid hedge]

It dosent work
I have a plugin named "FormatAsMoney" for making 1000 to 1k

depend:
  - "FormatAsMoney"

[chrome beacon]

You need to import the plugin in to your project if you want to access classes from it

[placid moss]

yea

you need to add the plugin jar as a dependency

or use maven api if available

[placid moss]

^

[timid hedge]

But i dont understand what you mean with a and b

So i need to add it to my pom.xml right?

[chrome beacon]

Yes

[timid hedge]

But what should i switch out with what to add my other plugin?

      <dependency>
          <groupId>org.spigotmc</groupId>
          <artifactId>spigot-api</artifactId>
          <version>1.8.8-R0.1-SNAPSHOT</version>
          <scope>provided</scope>
      </dependency>

[placid moss]

just add the built jar as a dependenc

or use maven install i think?

[chrome beacon]

???

[placid moss]

and then use local dependency

right

[chrome beacon]

Yeah mvn install

No need for jar depend

[placid moss]

lol i dont use maven ;-;

yea

[chrome beacon]

Same goes for gradle

[timid hedge]

.

[drowsy helm]

what are you using instead

[placid moss]

you dont have to change the other plugin

just run mvn install in the root of the other project

an then add the local dependency

[timid hedge]

How?

[placid moss]

is this library yours or not yours

[tawdry echo]

i want to get all stone from player inventory but it must be divisible by 4 then remove how can do it?

[timid hedge]

Dude what are you talking about?
I just want so i can use my FormatAsMoney in my other plugin so i can make 1000 to 1k

[drowsy helm]

check if amount % 4 == 0

[drowsy helm]

this sounds like a method you canm just copy paste over

why does it need a whole dependency

[timid hedge]

Becuase i also need to have the method in other plugins
And i dont see any reasons for taking this method into every plugin

[placid moss]

i dont think you should have a library for one function lmao

[drowsy helm]

that would make sense if it was some mult faceted method but its a util method

[quaint mantle]

whats the best way to do like a raycast/linetrace out of the player's eye until i hit an enemy?

[drowsy helm]

unless therei s some config that it depends on in the plugin you are just wasting time importing it

[chrome beacon]

Use the api

[placid moss]

raycast with raycastresult

raytrace with raytraceresult sorry

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/util/class-use/RayTraceResult.html

[shadow night]

how do I check if something is usable as fuel in furnaces?

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Material.html#isFuel()

[shadow night]

and how do I check burning time?

[placid moss]

i dont think theres api for that

use an enum to manually list i think?

[shadow night]

._.

[drowsy helm]

no there is

[shadow night]

oh thank god

[drowsy helm]

im trying to read my horrendous code

[chrome beacon]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/FurnaceBurnEvent.html#getBurnTime()

You could check it in the event

[drowsy helm]

    private int getSmeltTime(Material mat) {    
        return getFurnaceRecipe(mat) != null ? getFurnaceRecipe(mat).getCookingTime()/20*1000 : 0;
    }
    
    private float getSmeltExp(Material mat) {
        return getFurnaceRecipe(mat) != null ? getFurnaceRecipe(mat).getExperience() : 0;
    }
    
    private FurnaceRecipe getFurnaceRecipe(Material mat) {    
        Iterator<Recipe> iter = Bukkit.recipeIterator();
        while (iter.hasNext()) {
            Recipe recipe = iter.next();
            if (!(recipe instanceof FurnaceRecipe)) continue;
            if (((FurnaceRecipe) recipe).getInput().getType() != mat) continue;
            return ((FurnaceRecipe) recipe);
        }
        return null;
    }```

[placid moss]

wow cool

[shadow night]

I have nowhere to use that event

[drowsy helm]

have to get the recipe then the time form that

[placid moss]

i think thats the time remaining right

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/InventoryView.Property.html#FUEL_TIME

[placid moss]

that is unrelated

[eternal oxide]

lots of values there

[placid moss]

that is the progress of the little bar

not the fuel time of the fuel

[eternal oxide]

there is also burn time ticks for fuel etc

[drowsy helm]

TICKS_FOR_CURRENT_FUEL

is the one

but that only works when afurnace is populated with a fuel item

cant just get it from the material

[chrome beacon]

That would require the furnace to be burning already

[shadow night]

and my furnace won't be burning by itself

it does that from code

[vivid cave]

Do armor types have an actual impact on the stats ?
or is an armor entirely described by its attributes ?
(which ofc are initially given based on the type of the armor)

My question can be rephrasd:
If two armors, whatever their types, have the same attribute modifiers/data besides the type (gold / diamond etc), are they just a copy of each other ?

[drowsy helm]

just use the recipe method its much easier

[placid moss]

i think material matters when comparing armors

so they wont be a copy

but stats can be changed without changing the armor type

so you can have two different types of armor with the same armor stat using attributes

[chrome beacon]

Durability is hardcoded

[vivid cave]

yeah ik about that but i already have my own durability class

https://i.imgur.com/l8760GI.png

do you guys think that what i did in the screenshot is sufficient ?

(only for protection wise)

[echo basalt]

1 - what the actual fuck is that color scheme

[vivid cave]

with testing it feels like armors are the same but i ain't entirely sure

[chrome beacon]

Screenshot of code 💀

[drowsy helm]

oh my god

are you coding with hyperlinks

holy fuck

[vivid cave]

😢

[chrome beacon]

Don't send text as images

That's just a waste

[vivid cave]

but i didn't wanna shove the wall of china up your eyes

😢

[chrome beacon]

?paste

[undone axle]

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

[vivid cave]

mk

[vivid cave]

https://paste.md-5.net/nanunudapu.cs ?

wait don't mind the CompoundTag stuff (its unrelated to my question)

i only talk about sheer protection, not damage/durability

[chrome beacon]

That probably wouldn't enough

Armor has protection values by default. I'm not sure if those are included in your calculation

Do test and see if it works

[vivid cave]

well my test seems to be pretty satisfying tbh but i feel like i'm coding with the ass rn and fluking stuff you know what i mean

till i have no proof this is exact testing won't convince me

but for example, each need the same amount of hits till player dies

and i fear of not covering every scenarios too tbh

maybe it's just a luck that my testing work for the specific armors i took

[chrome beacon]

Then test some other combinations

Or write an automated test

[vivid cave]

hm, idk what to test too tbh, i have tested basic armors, armors with same enchants,

all that in my manual testing seemed to work fine

[chrome beacon]

Then it's fine

[vivid cave]

mk

will prolly move to packets tho tbh

idk

[chrome beacon]

Not worth it

[vivid cave]

yeah

anywawy thx!

[glad prawn]

[drowsy helm]

oops

[glad prawn]

wat

[slow temple]

im new to java plugin making, is there a way to create a custom mob class that extends the zombie class

[drowsy helm]

yes it's somewhat complex though

are you new to java in general

[slow temple]

i know c# well and they're basically the same imo

[drowsy helm]

on the surface, yeah

[slow temple]

i know the basics of java

[shadow night]

they're similar but not the same

[drowsy helm]

https://github.com/MitchGB/MinecraftEnhanced/tree/main/src/main/java/com/buoobuoo/minecraftenhanced/core/entity

https://github.com/MitchGB/MinecraftEnhanced/blob/main/src/main/java/com/buoobuoo/minecraftenhanced/core/entity/impl/ViciousWolfEntity.java

[slow temple]

the syntax is similar, so i can read java

ty

[drowsy helm]

thats some implementations ive done if you wanna try and decipher it

there are a few tutorials on the forums aswell

[slow temple]

where do i get the net.minecraft import

[drowsy helm]

ah yeah that is the remapped jar

[shadow night]

you have to get the api using maven or gradle, you should look at some beginner guides

[slow temple]

ok

[keen jolt]

I have a plugin that's reading some values from my config file, however my title string always comes back as null and is never read properly.
Method loading config:

public static void LoadFromConfig() {
    configTitle = plugin.getConfig().getString("scoreboard_title");
    configEntries = plugin.getConfig().getStringList("scoreboard_entries");
}```
Config:
```yaml
scoreboard_title:
  - §3Title Here§r
scoreboard_entries:
  - " "
  - "§6Phase: §e$phase_display_name"
  - "§e$phase_time_remaining §6Remaining"
  - "  "
  - "$team_player_count"
  - "   "
  - "§2§lBTekGuild Events§r"```

[drowsy helm]

you'll either have to get the remapped jar or use the nms equivalent

[drowsy helm]

why is it static

just pass the plugin instance

and use & instead of §

[keen jolt]

its called from a static method

[drowsy helm]

definitely static abuse

it may be calling before getConfig is intializing properly

[keen jolt]

no, i've taken extra care to make sure it's not

[drowsy helm]

does scoreboard_entries load properly?

[keen jolt]

yes

every time

[shadow night]

why do people abuse static so often

[drowsy helm]

and where are you debugging it

could be in between the loading and debugging where it is messing up

[keen jolt]

what do you mean?

[drowsy helm]

like how are you verifying that it is null

[keen jolt]

It is initialized with a string value in the class, that method is called and should overwrite the value with whatever is in config

[drowsy helm]

can you show full code

just do a quick sout(plugin.getConfig().getString("scoreboard_title"))

[keen jolt]

sure hang on

[keen jolt]

Ok I changed the config from § to & and did sout in the main class as well as that method and it works in both places

maybe the symbol was the problem

[drowsy helm]

yeah just use alternate colourcodes

that character can fuck alotta things up

[keen jolt]

shoot it's still the same thing in game, scoreboard title shows up as my predefined string

[shadow night]

could getting and setting persistent data container every tick multiple times heavily mess up performance? Or is it pretty much okay?

[slow temple]

are there any tutorials you could send me

[drowsy helm]

its all on mem so its fine

but sounds like that could definitely be optimised

[shadow night]

I remember on spigot there was some guide for newbies I followed but I don't remember where and what, you might just google

[shadow night]

do you know how?

[drowsy helm]

https://www.spigotmc.org/threads/1-18-creating-custom-entities.538519/

[drowsy helm]

depends, what is your usecase?

like why are you updating it every tick

[shadow night]

you know the mod ic2?

[drowsy helm]

yup

[shadow night]

basically, I'm trying to remake ic2 machinery using plugins

[drowsy helm]

gotcha

well i mean in isolation it wont be bad but if theres hundreds of PDCs updating every tick

that could be pretty bad

consider batch calculation and on-request calcs

[shadow night]

I rn have a furnace, the fuel slot is for fuel, the cooking time and fuel time is for fuel time and the result will be a glass pane (red, yellow, green) which name is the amount of energy stored from max

[drowsy helm]

name?

why name

[shadow night]

like, when you hover over the pane it tells you xxx/xxx (Energy Units) or something

[drowsy helm]

oh gotcha

and that has to update each tick

[shadow night]

yeah, checks and stuff

[drowsy helm]

Okay so hear me out, might be much more complex but if you REALLY want perfomance.
Keep track of last interaction with the block, if the player is currently interacting with the block update each tick, if not PAUSE the calculation, and next time they interact get the time between now and last interaction and calculate the energy produced between interactions

can be made into a formula, and means you only every have to calculate it once when the block is not being interacted with

and every tick only when the player is viewing it

idk if that makes much sense

[shadow night]

but if it's connected to anything that takes energy wouldn't that break?

[eternal oxide]

or update ticking machines every second, unless being viewed, then per tick

[shadow night]

hmm

[drowsy helm]

if oyu calculate the output per minute or something

then you can just pass that into others' calculations

it can all be reduced to one or two equations and not have to do it per tick

[shadow night]

hmm, makes sense

[drowsy helm]

pretty sure thats how games like factorio and satisfactory do it

iterating through every single machine, every tick would add up exponentially

[shadow night]

so, instead of doing stuff every tick, I just calculate a formula to see how much its producing and use that?

[drowsy helm]

yeah, and if its something with limited runtime keep track of how long the fuel will last for example

[shadow night]

you read my mind, I just wanted to ask about fuel

[drowsy helm]

so

lastInteractionMillis = last interaction in time milliseconds
maxLength = how long fuel will last in milliseconds

output = min(lastInteraction - nowMillis, maxLength) * energyPerMillis

something like that

[shadow night]

hmm, that makes sense

[drowsy helm]

thats probably the most performant way to do it, but more work to figure out calculations

but will be hundreds of times faster than calculating each tick

[shadow night]

couldn't I count the time in a way to know how much fuel is spent if it's more than 1 and if it's more than the total amount of fuel just calculate it at that point?

[drowsy helm]

i dont understand sorry

could you rephrase

[shadow night]

its hard to explain

hmm

I'm confused now

oh no

[drowsy helm]

so with your furnace example does is the fuel worth x energy

or the furance constantly output x energy and the fuel powers it for x ticks

[shadow night]

🤔

[drowsy helm]

im confused with how the system works

[shadow night]

im generally confused

[drowsy helm]

okay so the furnace has xxx/xxx charge right

[pseudo hazel]

start by just making the machines run at 1 second per tick

[drowsy helm]

so it acts as a battery aswell as a generator

[shadow night]

yes

just like in ic2

[drowsy helm]

never played ic2 just know what it is so im pretty fresh on this

[pseudo hazel]

you would almost certainly need something that coordinates all updates

if you arent going to be updating every tick

[shadow night]

o.o

[drowsy helm]

hold up im watching a video lol

[pseudo hazel]

since if you only update every so oftern, you would have to wait for some kther machines output

[next stratus]

Hey, I'm trying to remember the name of something but I can't remember it for the life of me, it allows you to spawn different items with different sizes etc. I think it's a 1.120 thing?

[tender shard]

Item Displays?

1.19.4

[slow temple]

im running buildtools.jar but no jar files are created, only java source files

[tender shard]

did it say "BUILD SUCCESS" at the end?

[next stratus]

Hero!

[drowsy helm]

then you end up running into circular dependencies and many more htings i would assume

[tender shard]

there's also block displays and text displays btw

[pseudo hazel]

yes

[slow temple]

dont think so

[drowsy helm]

ends up making life harder

[pseudo hazel]

but I dont see another way to do it

[tender shard]

well what does it say?

[next stratus]

Thank you for that mfn 🙂

[drowsy helm]

the way i was describing before

[tender shard]

np

[shadow night]

oh gosh

[pseudo hazel]

unless you have the generator pushing ticks to other machines

[slow temple]

already closed cmd

[drowsy helm]

calculate it on request instead of per tick

[tender shard]

then run it again

[drowsy helm]

just calculate averages on request

[next stratus]

You know when you know exactly what you want but you can't work out what it's called? 😅

[drowsy helm]

its one calculation maybe every 10 seconds vs 100 a tick

[shadow night]

true

[drowsy helm]

okay i see how it works now

bare with me im gonna write something up

[pseudo hazel]

when is the request though

[drowsy helm]

when a block is queried (i.e player interaction or outputs an item) it causes a chain of queries to other connected blocks

meaning calculations are only being executed when they are required

[pseudo hazel]

yes I guess

but what about something that does not take item input or output

but then ither machines rely on it

[shadow night]

solar panels?

[drowsy helm]

the other machiens which rely on it will query it

the queries are chained

[pseudo hazel]

okay

[shadow night]

kinda like

• hey, I need some energy
• here, take 300 units
  ?

[pseudo hazel]

how does that not result in circular updates

[drowsy helm]

Fuel{
  amount
  energyPerConsumption = energy once fuel is consumed 
  consumptionTimeTicks = time in ticks which it takes to consume
}


lastInteractionTicks = time in ticks when last queried
lastInteractionEnergy = energy amount when last queried
maxEnergy 


on query ->
  currentInteractionTicks = time now in ticks
  
  currentEnergy = min(maxEnergy, lastInteractionEnergy + min(Fuel.amount, floor((currentInteractionTicks - lastInteractionTicks)/Fuel.consummptionTimeTicks)) * Fuel.energyPerConsumption)

then amount of fuel used is just

min(Fuel.amount, floor((currentInteractionTicks - lastInteractionTicks)/Fuel.consummptionTimeTicks))

[pseudo hazel]

okay that makes sense

[shadow night]

holy wheat

[pseudo hazel]

so what about a chain of machines that could run in a circle

[shadow night]

like?

[pseudo hazel]

idk some process

but with the recipes you can go back and forth and convert the same item etc

[drowsy helm]

letes say a furnace generates power, which powers a coal miner which feeds back into the furnace

[pseudo hazel]

which will inevitably happen with enough recipes and machines

yeah

[ionic terrace]

With making a bungee plugin, I presume you have to put the file in the plugins folder of the server?

[drowsy helm]

each time the miner generates coal, it will update the furnace

and queries it befoer it updates it

[shadow night]

lag machines go brrrr

[pseudo hazel]

okay so generators never update on their own

[drowsy helm]

so yeah you would have to have some limiter

[shadow night]

yeah, the built jar

[drowsy helm]

yeah thats a hard one steaf

i still feel updating every x time can be really detrimental

[pseudo hazel]

and how do you know when item machines should update if not being checked by the player

or do you just not

and only update retroactively

[drowsy helm]

this makes me want to try and write one of these lmao

[shadow night]

this shits confusing

[drowsy helm]

well the easiest way is updating every tick

[shadow night]

lag machines be like

[drowsy helm]

but performance is going to plummit with more than say 200 machines

okay wait

wait

tick buffer

hear me out

[shadow night]

tick buffer?

[drowsy helm]

machiens can only be queried every x ticks

meaning recursive queries wont work

but the calculations will still work as they will still calculate between last interaction

so an infinite loop will work but only update every x ticks which

and the buffer queues the query

[pseudo hazel]

okay o one machine querying another that was already queried in that time will just say the result is incomplete?

[drowsy helm]

there has to be some sort of priority to the queries

[pseudo hazel]

lets say you have 2 coal miners and in between a generator

teh coal miners need energy so they will query the generator

but they cant do it at the same time

since the generator can only push every x ticks

is that what you mean?

priorities will have to work based on direction

[drowsy helm]

yeah you raise a good point

raydan i hope you dont mind if i try and code this myself

i wanna give it a crack

[shadow night]

who am I to forbid it tho?

[pseudo hazel]

and then make a lib out of it

[noble lantern]

done, made it ||/s||

[pseudo hazel]

xD

[drowsy helm]

nah more like give up after a day

[shadow night]

make an bukkit energy library

[noble lantern]

i want to

i wanted to do ae2 in spigot

[shadow night]

thats cool

[noble lantern]

i have a whole idea for it laid out too but... effort

and no one would use vanilla energy tbh, at least thats why i never gave it a crack

[noble lantern]

you can run most machine ticks off thread as well

[shadow night]

maybe if we made the BE library (Bukkit Energy) we'll have more tech plugins(?)

[pseudo hazel]

xD

yeah but it would have to be good

[shadow night]

it should implement what we talked about and some abstract classes

[noble lantern]

would need to be highly abstract like Forge Energy is (or vault)

[ionic terrace]

Also is it possible to create a Spigot plugin that can also be used on Bungeecord servers? I know they have different API's but it could work with the right file structure?

[shadow night]

yep

[drowsy helm]

definitely

[noble lantern]

ngl once i finish oraxen support for musepluse i should take a lok into that idea again since block displays are a thing

[drowsy helm]

i will be back in 20 hours

[noble lantern]

block displays for dah pipes

[shadow night]

that scares me

[noble lantern]

i love it

fuckin love ae2

[drowsy helm]

i just statrted satisfactory a week ago

have 70 hours already

[shadow night]

it's awesome yet scary

[noble lantern]

i wanna give satis a try but myeeeeh

gregtech guys

nomifactory gtceu trust me

https://www.curseforge.com/minecraft/modpacks/nomi-ceu

[shadow night]

make sure you don't get fractureiser

jk

You can get it, I have no problems with that

jk

[noble lantern]

took me like

4 mins to figure what that was

then i forgot cf had that virus a week ago or so lmao

damnit now im all motivated to make a new plugin cause i hopped in here smh

[shadow night]

Relatable

[noble lantern]

https://skmedix.github.io/ForgeJavaDocs/javadoc/forge/1.11.2-13.20.0.2228/net/minecraftforge/energy/IEnergyStorage.html

ngl this would be a stupid easy thing to transfer over to spigot to get working as a vault-style API and you could have people register theyre own energy storage type

[shadow night]

Hmm

[noble lantern]

and you could make it only use referances to blocks (machines), meaning it could almost be entirely async

as 9/10 times ur never gonna actually need main thread stuff when a machines processing stuff like making energy

i hate myself with these ideas

[shadow night]

🤔

[noble lantern]

its the 4am talkin

[shadow night]

1:27 PM for me lol

That's why the internet is cool

[native gale]

Hmm

[noble lantern]

yes you get to hear belligerent american rambling at 4am about stupid ideas xD

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

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

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[gloomy ocean]

can someone please help, I need a plugin that limits the amount of a certain item someone can have on them at one time, but I can't find one

(Example, you could only have 2 totems or 5 golden apples on you and it won't let you get more than that)

[native gale]

That's not what I want

I need to download Java 20 JDK and I kinda forgor

Where do I legally get it

[noble lantern]

oracle site :p

jdk/jre are bundled together in modern versions of java dont need to download 2 anymore if thats what ur thinking

just the one jar from oracles enough for dev + everyday use

https://www.oracle.com/java/technologies/javase/jdk20-archive-downloads.html

you need an account iirc

[glad prawn]

i can download it without login

[noble lantern]

oracle scammed me

[quaint mantle]

okay so, im trying to add an ability system to my custom items, for the items i have a custom class that looks like this for example (HeadItem extends the class "CustomItem")

public class HighlightBread extends HeadItem {
    public HighlightBread() {
        super("http://textures.minecraft.net/texture/c86f7f24d45841c658730f5ea60c206663bbbd62ba67cac223d1483911884e45");
    }

    @Override
    public String getDisplayName() {
        return "%%COLOR_RED%%Highlight Bread";
    }

    @Override
    public String getId() {
        return "highlight_bread";
    }

    @Override
    public boolean isStackable() {
        return true;
    }

    @Override
    public EquipmentSlot getEquipmentSlot() {
        return EquipmentSlot.HAND;
    }

    @Override
    public Rarity getRarity() {
        return Rarity.UNOBTAINABLE;
    }

    @Override
    public List<String> getLore() {
        return null;
    }
}

Now what would be the best way to add an ability? I tried using an interface but before the ability gets used i want to do a check where u have enough "Mana" to use the ability, i want that in every ability, but i cant do that check with an interface since u cant have functions with definitions in there.

[remote swallow]

Openjdk better

[green plaza]

u can have fucntions with definitions

use default key word

[quaint mantle]

o

then interfaces it is

cus thats prob the easiest way to do it

[green plaza]

The easiest way but no the best way is to add method getAbility() that will return Ability object

[ionic terrace]

Is there an easy way of doing it as I've gotten to the point where I'm checking if bungee is installed and then calling completely replaced functions specific to bungee

[green plaza]

And this Ability object can have classes that extends it, for example u can Ability class and then u have WaterAbility instace that allow you to create WaterAbilities

[quaint mantle]

oh yea i could just return null if there is no ability

[green plaza]

or use Optional.ofNullable

[quaint mantle]

the hell is even that

[green plaza]

Optional allows you to check if something is null or not

I'll give u an example

            Optional<User> optionalUser = UserManager.getUserByUUID(player.getUniqueId()).findFirst();
            if (!optionalUser.isPresent()) {
                return;
            }
            User user = optionalUser.get();

And here you are sure that user is not null

[quaint mantle]

but in my customitem class i would add

public Ability rightClickAbility() {
        return null;
    }
    
    public Ability leftClickAbility() {
        return null;
    }

right?

cus i can overwrite m

or Optional<Ability>

[green plaza]

I dont know the whole project structure

So its hard to say

[young knoll]

Optionals are kinda meh

[green plaza]

https://tenor.com/view/mujikcboro-seriymujik-gif-24361533

Optionals:

[quaint mantle]

i mean adding this, whenever i wanna trigger the event i check if the ability is null

[green plaza]

U can do that

[ivory sleet]

Yes but no

In java they’re clumsy (hence why the practice is only to return them from methods)

[solid cargo]

do i need packets/nms in order to prevent a hostile entity suddenly wandering away for a little bit?
https://youtu.be/JmYODjNHy9A?t=89
shown here

[ivory sleet]

Nope

Pathfinding is pretty much server sided

Maybe nms ye

[tall siren]

Hio! I'm struggling to configure NMS..

I heard in a forum post that you need to include spigot-server.jar, but I'm unfortunately unable to get it to work?

I keep receiving error: package net.minecraft.server does not exist, even though I'm using the --class-path argument correctly with both spigot-api.jar and spigot-server.jar.

Can anyb'dy please help meeeeeeeeeeeee.. ? ..

?nms

[undone axle]

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

[eternal oxide]

if you don;t want to use maven the easy way...

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[tall siren]

I don't have Maven.

Or CMake for that matter.

[chrome beacon]

Um this is Java so no need for CMake

[tall siren]

I'm just using make.

[chrome beacon]

For Java?

[tall siren]

M'hm. Make as in build-essential/oldstable,now 12.9 amd64.

I use it for everything.

[quiet ice]

I'm impressed. People generally don't do that

[tall siren]

Why's it impressive and why don't people generally do it?

[quiet ice]

Because we have maven and gradle. If you want it complicated there is ant

But make is very rarely used in java space

[chrome beacon]

I haven't seen anyone use make for Java

[quaint mantle]

wait my math is being dumb, if i wanna draw a line between two points with particles, like from the player's eye to a certain point, whats the best way?

[quiet ice]

Regardless, you don't want to use make in conjunction with NMS. If you really wanted to you'd need to be very aware of the tools you have at your disposal (such as tiny-remapper, mojmap, etc.) but chances are you don't

[tall siren]

Maven and Gradle are bloatware.

Sort of like CMake in a way..

[tall siren]

Why would I need to know about those?

Thus far I've not needed anything other than make?

[quiet ice]

Because otherwise you'll have a LOT of pain going forward

[tall siren]

I technically don't even need make, I could simply use shell scripts like I used to.

[quiet ice]

NMS is obfuscated by default. TR and mojmap helps to get sane names

[shadow night]

hmm, so, I thought a little bit and every time anything accesses the ticking machines it has to updated

[tall siren]

Uhuh..

Couldn't one just use a Java-decompiler?

[quiet ice]

You may (read: you definetely given that you won't use an IDE) also need to use Recaf or if that is bloatware too - Quiltflower and CFR.

[tall siren]

I use vi.

Vim is a little to far on the bloated side for my taste honestly.

[quiet ice]

You seem to not understand me: In NMS almost all methods have names such as a, b, c, etc.

[shadow night]

that's a pain

I've seen and tried that myself

[quiet ice]

I'll bet a wager that in fact your vi install is vim

[shadow night]

what do you think about neovim then

[quiet ice]

I haven't seen anyone ship naked vi installs seperately from vim for a while now.

[shadow night]

I haven't seen anybody use anything lower than neovim lol

[quiet ice]

Also, what the hell are you doing with spigot if that is your concern?

I'm the nano guy if I really need to change anything in the CLI. Though I can make use of basic vi

[shadow night]

nano is weird imo

[tall siren]

I've used ED before.

[quiet ice]

At least I don't have to remind myself of differences between distros

[shadow night]

you look like a person who would use notepad++ for coding tbh

[tall siren]

What's that?

[shadow night]

._.

[tall siren]

I used to use Leafpad but honestly gedit is better.

In regard to GUI Notepad software.

[quiet ice]

Under fedora using :save && :qa! suffices. However under Windows you need to use :wa && qa! which is just ... why

[tall siren]

:wq ; :w ; :q! is fine.

[shadow night]

I always do :wqwhen I use nvim

[quiet ice]

Won't flush all buffers

[tall siren]

Anyway can you stop judging me for what descendant of ed I use?

[shadow night]

maybe

[tall siren]

I need help including nms.

[shadow night]

sure

[tall siren]

If you don't know how, it's fine.

[alpine urchin]

lol

[eternal oxide]

I already told you how to use nms

[tender shard]

the only official way to use NMS in spigot is using maven

the blog post was linked to you above

[quaint mantle]

can i get the endpoint of a raycast without it having hit?

[tall siren]

But maven is bloaattttt!! 😭

[quiet ice]

Either don't (recommended), use maven (next best thing), use gradle with paperweight (if you are really desperate) or follow ElgarL's advice and use the correct (non-bootstrap) jar (if you are suicidial)
Those are your four options. No more no less

[eternal oxide]

I also told you how to use nms without maven

[shadow night]

bruh ._.

[tender shard]

what do you even need NMS for

[shadow night]

I use maven even on my tablet

[tall siren]

It was not obvious for me to see in the very very long tl;dr you sent me. I'm just a 14 year old girl not a leet hax0r..

[tender shard]

if you just use NMS without maven or gradle then you'll only have the obfuscated mappings with method names like a(), b(), c() and they will change on every new version

[eternal oxide]

you can read

[quiet ice]

Trolling pretty much 🤨

[tall siren]

Detecting TPS drops in regions and such.

[eternal oxide]

tps?

[quiet ice]

Bruh, this is spigot. The entire world is running at the same tps

[tall siren]

Yes, but what regions are taking the longest to tick?

[quaint mantle]

nice eye direction, game 👍

[eternal oxide]

games fine, your math is bad

[quiet ice]

And you can't modify nms as-is. If you want that while still keep using bukkit you need to use ignite or other similar transform layers
Which means that you cannot run your plugin under bukkit without these (usually external) transform layers

[quaint mantle]

Location endLoc = event.getPlayer().getEyeLocation().getDirection().multiply(getRange()).toLocation(caster.getWorld());
shouldnt that just get 7 blocks away from where the player looks?

[eternal oxide]

no

[tall siren]

I can detect what regions are taking the longest to tick, I just need to get the most TPS. Which I saw in a post on the forum, however I cannot manage to get it to work.

I keep receiving error: package net.minecraft.server does not exist, even though I'm using the --class-path argument correctly with both spigot-api.jar and spigot-server.jar.

[quaint mantle]

okay then what is the correct math

[eternal oxide]

you multplied a unit vector and made it a Location. You basically tried to draw a vector back to near 0,0,0

[quiet ice]

?bootstrap

[undone axle]

[quiet ice]

Then do /s/1.18/1.20/

[quaint mantle]

im already doing a raycast to check if i hit an entity or block but it returns null when it hits nothing sadly

[tall siren]

I've seen this, to me it seems to infer that one must be using maven.

[eternal oxide]

player.getEyeLocation().add(player.getEyeLocation().getDirection().multiply(7))

[tall siren]

I'm not a genius, okey..

[quaint mantle]

oh yea

[quiet ice]

It really does not

It just means that you need to depend on the ENTIRE contents of the bundler dir

[tall siren]

That's ridiculous.

[tender shard]

imagine asking for help and then ignoring every advice and calling it ridiculous lol

I'm out

[tall siren]

I'm asking for it to be done a certain way.. That's all..

I don't want to use maven, and I don't want to use eclipse.

[tender shard]

it's mentioned in the ?bootstrap message

[quiet ice]

Alternatively do the maven dependency resolution yourself. The org.spigotmc:spigot:1.20.1-R0.1-SNAPSHOT artifact is located under ~/.m2/repository/org/spigotmc/spigot/1.20.1-R0.1-SNAPSHOT/spigot-1.20.1-R0.1-SNAPSHOT.jar @tall siren

[tall siren]

I've done that. But I can't do it with NMS..

[quiet ice]

Did you run BT yet?

[tall siren]

BT?

What on Earth?

[quiet ice]

Oh god.

then you can't do anything on your system

[eternal oxide]

Then stop trying to dev for Minecraft

[quaint tapir]

I have a question about adding lore to items
can I add a line to the lore that is visible and also add a line which is hidden?
to the same item

[quiet ice]

Okay well then. I'll show you how to do it in the gray zone

[tender shard]

why do you want to use hidden lore?

the whole purpose of lore is to be visible

[quiet ice]

(what was that repository again?)

[quaint tapir]

to store data about the item

I'm making custom durability

[tender shard]

use the PersistentDataContainer to store information

[quaint tapir]

basically

[tender shard]

how to store data in items: https://blog.jeff-media.com/persistent-data-container-the-better-alternative-to-nbt-tags/

[tall siren]

I heard in a forum post that you need to include spigot-server.jar, but I'm unfortunately unable to get it to work.

Why won't it work?

[calm robin]

persistent data is too slow to be useful

[quaint tapir]

so theres no way to do it in the lore?

???

[tender shard]

it's not, its as fast as any other NBT tag (which lore is, too)

[eternal oxide]

do you mean how to get bukkit?

[quiet ice]

No the repo that published the spigot nms jars

[tender shard]

no, and it makes no sense

use PDC to store data in items

that's what it was made for

[young knoll]

?

[tall siren]

When inlcuding the spigot jar I keep receiving error: package net.minecraft.server does not exist, even though I'm using the --class-path argument correctly with both spigot-api.jar and spigot-server.jar.

[eternal oxide]

we already answered this one

Hm, I could swear it was https://repo.codemc.io/service/rest/repository/browse/maven-public/ but it doesn't seem as if they have it

[tall siren]

You told me to include the entirety of the builder thingy, yes. But I'm asking if there is a way to do this without having to be so ludicrous.

[eternal oxide]

no

[tall siren]

If perhaps you did answer me I might have missed it, and for that I apologise.

[eternal oxide]

stop being obnoxious and you'd have already had a full maven setup going

[shut sphinx]

you dont need maven lol

whats she trying to do?

[quiet ice]

Also: Maven is portable. You can just delete maven afterwards

[quiet ice]

NMS

[eternal oxide]

of course you don't, but its easier

[tall siren]

Thank you!!

[quiet ice]

Won't accept using bt and gradle either

[tall siren]

Somebody with a brain.

[tall siren]

They're all bloat..

[eternal oxide]

Can;t help then. Buildtools is the ONLY legal way to obtain spigot

[tender shard]

you guys haven't blocked her yet? lol what a waste of time

[shut sphinx]

no lol

[eternal oxide]

yes

[quiet ice]

spigot spigot. Not spigot spigot-api

[shut sphinx]

can get it from spigotmc right?

[eternal oxide]

no

[shut sphinx]

just download the spigot jar?

[quiet ice]

No

[eternal oxide]

no

[shut sphinx]

or u mean something else?

[eternal oxide]

no

[shut sphinx]

like not the server jar?

or the api?

or what?

lol

[eternal oxide]

there is no legally hosted spigot jar

[glossy venture]

ur trolling

[quiet ice]

She wants org.spigotmc:spigot:1.20-R0.1-SNAPSHOT

[tall siren]

No I'm gnot.

[eternal oxide]

She wants to use nms so needs the full spigot

[quiet ice]

Spigot only hosts org.spigotmc:spigot-api:1.20-R0.1-SNAPSHOT

[shut sphinx]

https://hub.spigotmc.org/nexus/content/repositories/snapshots/org/bukkit/bukkit/1.12.2-R0.1-SNAPSHOT/bukkit-1.12.2-R0.1-2

you mean that?

[eternal oxide]

Only legal way to obtain the full spigot is to run buildtools

[tall siren]

That's the API.

I need NMS.

I'm happy to work through obfuscation.

[glossy venture]

two options

1. run buildtools and install it into maven local/include the produced shit
2. use gradle and paperweight userdev for the paper api + nms (remapped automatically)

[tall siren]

What's option #3?

[quiet ice]

@tall siren Just depend on https://repo.rosewooddev.io/repository/public/org/spigotmc/spigot/1.20/spigot-1.20-remapped-obf.jar and get out of here

[glossy venture]

none

[quiet ice]

But beware: I've shown you how to do it illegally.

[glossy venture]

that might get taken down

• you still need specialsource in maven to remap your code

[quiet ice]

Meh it won't. It's publicly indexed at mvnrepository.com

[glossy venture]

oh

[eternal oxide]

md5 does go after maven repos hosting spigot

[glossy venture]

isnt it illegal

[quiet ice]

Ah huh

[glossy venture]

to host built jars

[eternal oxide]

he has to, legally

[tall siren]

I'm still getting the same issue.. package net.minecraft.server does not exist....

[proud palm]

hello I've a problem. I've installed a datapack and it's working in localhost with out op, but in the host it's need op

Because of fractureiser?
