@limber owl I want to make it change colors so why isnt it working:

                Color[] colors = {Color.RED, Color.ORANGE, Color.YELLOW, Color.GREEN, Color.BLUE, Color.PURPLE};
                int index;

                @Override
                public void run() {
                    if (index >= colors.length) index = 0;
                    Color color = colors[index];
                    index++;
                    leatherArmorMeta.setColor(color);
                    e.getItem().getItemStack().setItemMeta(meta);
                }
            }.runTaskTimer(plugin,20,20);```

[limber owl]

then do you want help or not?

[subtle folio]

a*

[ivory flume]

don't have to be so rude, I just want to know how long it should take to be considered "performing good"

[distant fern]

No progress

    public void onClick(InventoryClickEvent e) {

        ItemStack clicked = e.getCurrentItem();

        if (clicked.getType().equals(Material.DIAMOND_HOE)) {
            Bukkit.broadcastMessage("1");
            if (e.getCurrentItem().containsEnchantment(Enchantment.MENDING)) {
                e.getCursor().setType(Material.AIR);
                e.getCurrentItem().setType(Material.AIR);
                Bukkit.broadcastMessage("2");
            }
        }
    }

[quaint mantle]

did you have to sign a NDA?

[limber owl]

java garbage collector does everything for you, you should be good

[ivory flume]

my laptop takes ~30 ms to run it, according to my tests.

[tardy delta]

if you dont show what you're doing i cant advise you

[ivory flume]

i hope thats not too long

[tardy delta]

to run what

[quaint mantle]

30ms?

honestly not that much time but still, that's a bit long?

[ivory flume]

it does have mutliple SQL queries

[chrome beacon]

SQL should be done async

[tardy delta]

do them in the async pre login event

after you checked if the player is allowed to join

[quaint mantle]

Bukkit#getScheduler#runTaskAsynchronously

or that yeah

[green prism]

    public void onPlayerCommandPreprocess(PlayerCommandPreprocessEvent event) {
            String[] args = event.getMessage().split(" ");
            if(args.length == 2) {
                if(args[0].equals("/creditcardconfirm")) {
                    event.setCancelled(true);
                    Player player = event.getPlayer();
                    CardConfigStep configStep = plugin.getCardConfigStep().getOrDefault(args[1], null);
                    new CardConfigStepTask(configStep, args[1], player, plugin);

                }
            }
        }
    }```


Doesn't works for hide command-log from console

[ivory flume]

well if I try to get stuff async won't that not update it in the main thread?

[limber owl]

do it like this

long task1 = Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new BukkitRunnable() {
            Color[] colors = {Color.RED, Color.ORANGE, Color.YELLOW, Color.GREEN, Color.BLUE, Color.PURPLE};
            int index;
            @Override
            public void run() {
                if (index >= colors.length) index = 0;
                Color color = colors[index];
                index++;
                leatherArmorMeta.setColor(color);
                e.getItem().getItemStack().setItemMeta(meta);
            }
        }, 0, 20);

[grim oak]

Hi so im making a custom GUI, and i want to make it so that when the user exists the gui (uses a chest gui) it returns the items they put in there back to their inventory, how would i do that?

[limber owl]

?spoon

[undone axle]

Spoonfeed a newbie for a day and they'll come back with more questions. Teach them to find their own answers and you'll both be better off: you won't get stuck answering the easy questions and they'll be much more productive than before.

[limber owl]

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

[green prism]

?helpmebro

[quaint mantle]

nice

[limber owl]

you should find everything in here

[quaint mantle]

its saying that:
'scheduleSyncRepeatingTask(org.bukkit.plugin.Plugin, org.bukkit.scheduler.BukkitRunnable, long, long)' is deprecated

[chrome beacon]

Listen to the InventoryCloseEvent and loop all the items in it. Then add them to the player inventory

[limber owl]

minecraft version?

[quaint mantle]

1.18.2

[chrome beacon]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[chrome beacon]

Read this ^^

[quaint mantle]

ok

[limber owl]

what's CardConfigStep

[quaint mantle]

Reason it's deprecated is because spigot recommends to use "Runnable" instead of their own "BukkitRunnable" @quaint mantle

[quaint mantle]

so how do we fix it

[limber owl]

this should work and not be deprecated

[quaint mantle]

So, basically you want to use Runnable instead of BukkitRunnable

[limber owl]

@quaint mantle

[quaint mantle]

ok I got it

[green prism]

a task, nothing to do with the operation of the log etc as the event has already been deleted

[chrome beacon]

You can use the BukkitRunnable directly that's fine

[quaint mantle]

ok

[limber owl]

and what does it do?

like

[green prism]

Creates a card after the click

[limber owl]

put Bukkit.getLogger().log(Level.INFO, "if statement working");
to the if statement

[green prism]

with some checks

[limber owl]

and see if it works

[quaint mantle]

I get this error:
[14:56:28] [Server thread/ERROR]: Could not pass event EntityPickupItemEvent to Magic_Armor v1.0-SNAPSHOT

[limber owl]

because i suspect that the / in the equals is unnecessary

[limber owl]

this has nothing to do with the runnables but with event

show us the whole log

[quaint mantle]

stacktrace

[chrome beacon]

Unchecked cast going by things posted earlier

[green prism]

[20:58:34 INFO]: if statement working

[limber owl]

i see

[green prism]

kydoky

[limber owl]

does the command work?

[green prism]

yep

[20:58:34 INFO]: Jaamin issued server command: /creditcardconfirm aZIQ8h4RMy
[20:58:34 INFO]: if statement working

[limber owl]

but if the command does the code you made

[green prism]

yep

[limber owl]

what does it do

[green prism]

starts the task
at the moment, it sends a message: "Jaamin you don't have enough money in your account"

[limber owl]

okay

[green prism]

?paste

[undone axle]

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

[green prism]

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

[limber owl]

i dont need this, paste a listener class

that you use

especially the part with that event

[green prism]

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

[limber owl]

move the logging after the new card config blah blah balh..

[green prism]

huhuh

guess

[limber owl]

move Bukkit.getLogger().log(Level.INFO, "if statement working"); to the 33 line

[green prism]

yeah, it works normally

[ripe owl]

can i ask 1.8 minecraft dev question?

[limber owl]

yes

[green prism]

sure

[ripe owl]

paper community don't allow 1.8 question

ah

ok

i have some problem: players are damaged when spam blockhitting, they keep their sword blocking state so every damage they have reduced by sword blocking though they are not sword blocking state (no holding right click)
bukkit versions: 1.8.9

[limber owl]

try doing the event.setCancelled(true); at the start on line 25, that should show us if it shows any command in console

[limber owl]

well, this is not a dev question

[ripe owl]

ok

so is there any way to set player's sword blocking state?

[limber owl]

if you need help with code, come back and we can help but I'm not sure how to help with this

[limber owl]

well, by right clicking in game but im not ure if its in a event, try looking it up in a google

[green prism]

nothing

as always

[limber owl]

okay, now we know that it doesnt hide it in console

[green prism]

[21:07:58 INFO]: Jaamin issued server command: /creditcardconfirm aZIQ8h4RMy
[21:07:58 INFO]: if statement working

[green prism]

HUHUHU

cool

[limber owl]

try doing event.setMessage("");

and remove event.setCancelled(true);

[green prism]

java.lang.IllegalArgumentException: Command cannot be empty

[limber owl]

? that fast, you implemented it, build the plugin restarted the server and tested it?

[green prism]

yep

I had already imagined

xd

[limber owl]

okay, do this, add the event.setMessage("/creditcardconfirm"); after the new credit card something and add the event.setCancelled(true); before creating that

wait

let me show you

    @EventHandler
    public void onPlayerCommandPreprocess(PlayerCommandPreprocessEvent event) {
        String[] args = event.getMessage().split(" ");
        if(args.length == 2) {
            if(args[0].equals("/creditcardconfirm")) {
                Bukkit.getLogger().log(Level.INFO, "if statement working");
                Player player = event.getPlayer();
                event.setCancelled(true);
                CardConfigStep configStep = plugin.getCardConfigStep().getOrDefault(args[1], null);
                new CardConfigStepTask(configStep, args[1], player, plugin);
                event.setMessage("/creditcardconfirm");
            }
        }
    }

like this

[green prism]

[21:14:05 INFO]: Jaamin issued server command: /creditcardconfirm aZIQ8h4RMy
[21:14:05 INFO]: if statement working

[limber owl]

remove the event set cancelled

or add the event set cancelled after the set message

[green prism]

that's beautiful

Unknown command + Command Works

[21:15:06 INFO]: Jaamin issued server command: /creditcardconfirm oAesqbNrgv

and obv

[limber owl]

frick

[quaint mantle]

pretty sure that only sets the command you execute

Not sure if it's possible without hooking into packets

[limber owl]

on spigot someone said: AuthMe hides login from console. It's open source, so you can check how they did it.

https://github.com/AuthMe/AuthMeReloaded

try looking deeper into that, but this is what they use:

@EventHandler(ignoreCancelled = true, priority = EventPriority.LOWEST)
    public void onPlayerCommandPreprocess(PlayerCommandPreprocessEvent event) {
        String cmd = event.getMessage().split(" ")[0].toLowerCase();
        if (settings.getProperty(HooksSettings.USE_ESSENTIALS_MOTD) && "/motd".equals(cmd)) {
            return;
        }
        if (settings.getProperty(RestrictionSettings.ALLOW_COMMANDS).contains(cmd)) {
            return;
        }
        final Player player = event.getPlayer();
        if (!quickCommandsProtectionManager.isAllowed(player.getName())) {
            event.setCancelled(true);
            player.kickPlayer(messages.retrieveSingle(player, MessageKey.QUICK_COMMAND_PROTECTION_KICK));
            return;
        }
        if (listenerService.shouldCancelEvent(player)) {
            event.setCancelled(true);
            messages.send(player, MessageKey.DENIED_COMMAND);
        }
    }

[slate mortar]

why isn't the Forward message going to like any server?

        Bukkit.getMessenger().registerOutgoingPluginChannel(this, "test:some_test_channel");
        Bukkit.getMessenger().registerIncomingPluginChannel(this, "test:some_test_channel", new de.cxlina.locallobby.Listener());

            ByteArrayDataOutput out = ByteStreams.newDataOutput();
            out.writeUTF("Forward");
            out.writeUTF("ALL");
            out.writeUTF("test:some_test_channel");
            ByteArrayOutputStream msgbytes = new ByteArrayOutputStream();
            DataOutputStream msgout = new DataOutputStream(msgbytes);
            try {
                msgout.writeUTF("Some kind of data here");
                msgout.writeShort(123);
            } catch (IOException exception) {
                exception.printStackTrace();
            }
            out.writeShort(msgbytes.toByteArray().length);
            out.write(msgbytes.toByteArray());
            e.getPlayer().sendPluginMessage(this, "test:some_test_channel", out.toByteArray());
            System.out.println("Sent Plugin Message.");

tried every combination of channels, server-names/types, even tried BungeeCord itself, nothing is apparently received on the second server.

and yes, there is a player on each server online

@green prism @limber owl

https://bukkit.org/threads/logging-filters.433571/ @green prism

how do i save an inventory into a config file?

[tardy delta]

that code looks meh

save the contents

[limber owl]

yes

[tardy delta]

an itemstack is (de)serializable

[tender shard]

turn the inventory contents into a list and then just do config.set("inv",myListOfItemStacks)

[slate mortar]

are you guys trying to hide specific contents from console or what

if so, i like seeing Zombie_striker lying to us :(

[thorny dawn]

Getting IllegalArgumentException: location.world on the "sender.teleport()" method. Could it be because the world has not been created yet? (I am duplicating a world file before teleporting the player)

[slate mortar]

oh god, my eyes lmfao

again

[thorny dawn]

LOL

[slate mortar]

why you do this to me again

IVE DONE NOTHING TO YOU

[thorny dawn]

im evil

[tardy delta]

aa kotlin

[slate mortar]

:(

[thorny dawn]

kotlin is for the real chads

java is for the weak

[tardy delta]

kotlin is a very funny language

[slate mortar]

LIES EVERYWHERE

[thorny dawn]

NAH

[slate mortar]

kotlin is ugly af imo

my eyes are bleeding rn

[thorny dawn]

"public static main void(String[] args)" 🤓

[ivory sleet]

I mean kotlin kinda sucks but at the same time, its splendid

[slate mortar]

what?

[ivory sleet]

I mean verbosity isnt necessarily bad

[green prism]

TextComponent ClickSpam

[thorny dawn]

well

[ivory sleet]

for enterprise, verbosity has been proven quite effective

[green prism]

that's the only reason

[thorny dawn]

u get away from javas boilerplate with kotlin

[tardy delta]

what does verbosity mean?

[ivory sleet]

many words

[tardy delta]

👉👈

[ivory sleet]

Like classes named AbstractObserverVisitor or sth

yk

[ivory sleet]

yes but verbosity and boilerplate is not the same thing

[thorny dawn]

anyone who knows kotlin who can help?

not looking at @slate mortar

[slate mortar]

ofc not

my eyes are still bleeding

[ivory sleet]

this has minimal boilerplate public static main void(String[] args) unless we're talking in terms of functional programming

[thorny dawn]

sorry next time ill convert it to java so u can see

[humble tulip]

you need to use the bungeecord channel

[ivory sleet]

the only paradigm that still allows for one letter variable names

[slate mortar]

read please

[ivory sleet]

ceryth still

[slate mortar]

the bottom of the message

[thorny dawn]

well

ive done some android development before

so it was easier for me to adopt with kotlin

[ivory sleet]

I think we told you already about the issue

[thorny dawn]

wait where

[ivory sleet]

oh im not complaining about kotlin

[thorny dawn]

im confused

😭

[twilit pulsar]

https://gyazo.com/5065815be6571c469476497f3b85d5fd so im just confused of what i have done wrong

[green prism]

I've tried like that but nothing

    public void onPlayerCommandPreprocess(PlayerCommandPreprocessEvent event) {
        String[] args = event.getMessage().split(" ");
        if (args.length == 2) {
            if (args[0].equals("/creditcardconfirm")) {
                event.setCancelled(true);
                Bukkit.getLogger().log(Level.INFO, "if statement working");
                Player player = event.getPlayer();
                CardConfigStep configStep = plugin.getCardConfigStep().getOrDefault(args[1], null);
                new CardConfigStepTask(configStep, args[1], player, plugin);
            }
        }
    }```

[ivory sleet]

the world is null

[thorny dawn]

have u even imported this

[slate mortar]

uhmmmmm

[twilit pulsar]

here

[ancient plank]

kekw

[slate mortar]

i honestly have no idea if i want to even answer this

[thorny dawn]

the thing is the world isnt corrupted i can join it normally idk why its doing that

[ancient plank]

red things in intellij (base theme) are errors, fun fact

[ivory sleet]

ceryth what does GetWorldToQueue().getWorld() do?

[slate mortar]

base theme? who tf uses a theme that changes the error color

[ancient plank]

the person above your message does

[slate mortar]

._.

imagine

[twilit pulsar]

https://pastebin.com/vK7qZdSb

[ivory sleet]

feels like you could make that into a companion object and put the function inside the companion, but besides that what world name does it yield?

like if you were to debug/print

[slate mortar]

is this a joke or is it real?

[twilit pulsar]

its not a joke

[slate mortar]

in that case please

where do you expect to get the sender from

[tardy delta]

from the matrix

[slate mortar]

i feel like this channel slowly gets worse every day

idk

[ancient plank]

I like how nobody's mentioned the

if(player.hasPermission("permission"));

[thorny dawn]

im the main issue

with posting kotlin code

[slate mortar]

i'm the main issue
for not beeing funny enough

i'm sorry people

i'm trying to be better the next times

[tardy delta]

😞

[echo basalt]

I've had people reply to some old help requests with php code

[iron glade]

wtf?

[twilit pulsar]

Im sorry

eminem.

[iron glade]

if(player.hasPermission("netcore.fly"));``` What's up with this

[twilit pulsar]

whats wrong?

[iron glade]

;

[tender shard]

it makes no sense

[iron glade]

why is there ; at the end

and no {

[twilit pulsar]

cause im better.

[tender shard]

it's valid syntax but it makes absolutely no sense lol

[twilit pulsar]

the plugin works fine tho?

[iron glade]

Just cause it works doesn't mean there's no room for improvement

[tender shard]

    public NamespacedKey getKey(String name) {
        boolean $$ = true;
        if($$);
        if(false);
        else;;;
        {{{{{ return KEYS.computeIfAbsent(name, __ -> new NamespacedKey(this, name)); }}}}}
    }

I like this

[twilit pulsar]

so you want me to nchange to that?

[lethal python]

guys if you had an item which had an ID number in its lore which do you think would look better:
№39
#39

which character looks better

[iron glade]

-> #

[ivory sleet]

or some key tag like ID: 678

[tender shard]

I'd use a full sentence like
"The item to which this lore belongs to has an ID of 39. Have a nice day."

[tardy delta]

does Class::isAnnotationPresent checks all the variables and fields for the annotation or only the class declaration?

[ivory sleet]

only latter

[tender shard]

the class

[lethal python]

xdxdxd

[tender shard]

you'd have to loop over all declared fields and methods if you want to know whether that annotations appears SOMEWHERE in the class

[tardy delta]

ah

[tender shard]

sth like this

    public static boolean doesContainAnnotation(Class<?> clazz, Class<? extends Annotation> annotation) {
        if(clazz.isAnnotationPresent(annotation)) return true;
        for(Field field : clazz.getDeclaredFields()) {
            if(field.isAnnotationPresent(annotation)) return true;
        }
        for(Method method : clazz.getDeclaredMethods()) {
            if(method.isAnnotationPresent(annotation)) return true;
        }
        return false;
    }

although I wonder why someone would need that

[tardy delta]

vewy important

[lethal python]

they are

[tardy delta]

ah i get it

[ivory sleet]

remember the annot needs to be set to runtime retention

[quaint mantle]

How do I fix this:

                Color[] colors = {Color.RED, Color.ORANGE, Color.YELLOW, Color.GREEN, Color.BLUE, Color.PURPLE};
                int index;
                @Override
                public void run() {
                    p.sendMessage("hhh");
                    if (index >= colors.length) index = 0;
                    Color color = colors[index];
                    index++;
                    leatherArmorMeta.setColor(color);
                    e.getItem().getItemStack().setItemMeta(meta);
                }
            }, 0L, 20L);```
its sending (hhh), bu its not chaning the color of the item

[ivory sleet]

yep

because p.sendMessage("hhh");

[silent topaz]

fax

[thorny dawn]

oh no

[hybrid spoke]

maybe because you set the color of leatherArmorMeta but set meta?

[tardy delta]

ye

[thorny dawn]

@ivory sleet figured out the issue i had to do Bukkit.createWorld(WorldCreator($worldname))

cause the world wasnt loaded

[humble tulip]

Lol

[ivory sleet]

ye

makes sense

[echo basalt]

idk why but on 1.18+ using the WorldCreator class to load worlds just crashes the server

[tardy delta]

why are they doing this to me

newt time its going to be UwU i swear

[ivory flume]

whats the fastest way to check if a player is online

[tender shard]

by what? by their player object? by their name? UUID? ...

[ivory flume]

their name

[tender shard]

Bukkit.getOnlinePlayer("name")

it will be null when they are not online

[tardy delta]

.isOnline

[echo basalt]

¯_(ツ)_/¯

[tender shard]

erm

just getPlayer

not getOnlinePlayer

[tender shard]

good luck. the player is null when not online

[echo basalt]

it internally loops through all players anyways

[tardy delta]

wait my bad

thought you had a player obj

[hybrid spoke]

technically that will cause to not run the code

mission failed successful

[tender shard]

btw better use Bukkit.getPlayerExact

otherwise e.g. "mfn" would return the "mfnalex" player even though you wanted to look for "mfn"

[tardy delta]

i always forget 🥺

[ivory flume]

so getPlayerExact + null check? thank you 😄

[thorny dawn]

how do i detect when a player changes worlds?

[echo basalt]

PlayerWorldChangeEvent

or EntityWorldChangeEvent

[thorny dawn]

when does it fire?

[echo basalt]

seems like the actual one

when an entity changes the world...

[tender shard]

yep

[thorny dawn]

before or after world change?

[echo basalt]

pretty sure it's pre-world change

[thorny dawn]

oh

is there a way to get the destination world?

[echo basalt]

I'd need to look at the nms internals for that

[echo basalt]

it provides both worlds

[tender shard]

sure, just look at the event's javadocs

`jd-s

?jd-s

[undone axle]

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

[tender shard]

oh wait

yeah it's weird

it fires AFTER the player changed the world

[green prism]

Solved with

            @Override
            public Result filter(LogEvent event) {

                if (event.getMessage().getFormattedMessage().toLowerCase().contains("/creditcard confirm")) {
                    return Result.DENY;

                }
                return Result.NEUTRAL;
            }
        });```

That was the only solution

[tender shard]

so player.getWorld is the new world

and event.getFrom is the old world

[thorny dawn]

👍

[echo basalt]

yeah NMS seems to give me a similar answer

[limber owl]

lol, log4shell

[tender shard]

yeah it's quite obvious that it gets called after the world change because

1. no way to change the destination world
2. no way to even get the destination world
3. no way to cancel the event
   so yeah

but

[thorny dawn]

this is odd

its not logging out when the event fires

[tender shard]

you could probably just cancel it or change the world in playerteleportevent

[thorny dawn]

wdym?

i want the event to fire

but for some odd reason it isnt

and yes ive registered it

[tender shard]

I wasn't replying to your screenshot

[thorny dawn]

oh okay

[tender shard]

what's "send"?

[thorny dawn]

oh its just a quick custom logger ive made

[ivory sleet]

@EventHandler tho

unless you're registering a custom event executor

but doubtful thats the case

[tender shard]

lol I didn't check the annotation because they said "and yes ive registered it"

[thorny dawn]

lmao

i forgot ab it

well its 3am my brain isnt braining rn

[sterile token]

We dont need to use @EventHandler for listening to events?

If i dont use it them they are not listened

[tender shard]

I#m thinking about what's the best way to store custom enchantments. Maybe just a Map<String.Integer> as PDC on the itemmeta?

I came up with this: https://paste.jeff-media.com/?cb11c58a4343be68#CWhrbazAKv7SMMDEobrwM6Q8MsoXcjpADPRmYGPxh8KE

Of course I could replace the String key with a CustomEnchantment object but that's not important right now. I just wonder if there's any better way?

[ivory sleet]

?

wat

[sterile token]

Jeff

[ivory sleet]

did you even read the entire convo verano

[sterile token]

Im not convo

[tender shard]

bruh

[ivory sleet]

convo - conversation

[sterile token]

ohh ok

Sounds badly on my lang

[ivory sleet]

myea figured you might not know the abbreviation

anyway

[sterile token]

As usual

Conclure do you remember my menu lib?

[ivory sleet]

nope

[sterile token]

The one we dicuss more than 1h

In fact with the help of redempt i finally fixed it

[ivory sleet]

ye

[warm saddle]

How would I got about making a dropper inventory?

[tender shard]

Bukkit.createInventory(..., InventoryType.DROPPER)

[warm saddle]

thank you :)

[tender shard]

np

[grim oak]

If i have a chest inventory GUI is there a way i can check 2 slots for inputs and produce an output in another slot for all things that can be combined in an anvil. idk if i explained that very well

[tall dragon]

so bassically u want to recreate anvil mechanics in a custom gui

[grim oak]

yep pretty much

[river oracle]

you can it'd just be a tad hacky

[tall dragon]

or u can take the long way

and see how mc did it

[grim oak]

and what way is that?

[river oracle]

just some if checks and stuff

recipe handlers etc

I trust you can figure it out

[grim oak]

aight

[humble tulip]

I feel like this is the way

[tall dragon]

it will probably be much more clean and easier to add stuff to yea.

[humble tulip]

Yeah just copy paste the mc code

[grim oak]

where would i find the mc code for an anvil

[humble tulip]

In the server.jar

In mns

[grim oak]

aight thanks

[humble tulip]

Or however you get nms code now

[tender shard]

in net.minecraft.world.inventory.AnvilMenu

and in ItemCombinerMenu

(same package)

good luck in "copy pasting" that though lmao

[humble tulip]

Is it obfuscated?

[atomic flax]

Hello ! I'm trying to create a scheduled task like this :

Bukkit.getServer().getScheduler().scheduleSyncRepeatingTask(Plugin plugin, new BukkitRunnable() {
            public void run() {
                getLogger().info("Managed Task !");
            }
        }, 0L, 400L);

but the "Plugin plugin" appears in red and I don't know how to solve it... Otherwise, I can't find how to get a scoreboard value from a player who is not one like the players: Red for the number of remaining lives.

Thanks to you !

[humble tulip]

Lol

U cant define plugin there

[tender shard]

obviously it also accesses like 20 tons of otherNMS classes etc

[tall dragon]

copy paste those too 😄

[humble tulip]

Why does mojang still obfuscate the server.jar?

[tall dragon]

i have no idea. they obfusate it

then release an deobfuscate map

[tender shard]

you can't just "copy paste" the whole NMS anvil logic into a bukkit plugin lol. no matter whether it's obfuscated or not

[clever musk]

Do spigot nms mappings change with each major update, or minor update?

[humble tulip]

U really just need to see what checks it makes etc

[tender shard]

the mojang names keep the same unless mojang changed them

[clever musk]

Do spigot names stay?

[river oracle]

of-course

[tender shard]

there aren't really spigot names anymore, just the obfuscated ones. and yes, they obviously change everytime

[clever musk]

Rip

Ok

[tender shard]

why rip? that's what mojang mappings are for 😄

there is no reason, EVER, to NOT use mojang mappings

[clever musk]

I'm backporting my plugin and want to know if I need 6 modules for 1.16

For 1.16.0-5

[tender shard]

no, 3

1_16R1, 1_16R2 and 1_16R3

[clever musk]

Oohhh I see

Okay

[tender shard]

although tbh who the heck uses 1.16.1 or 1.16.2?

I'd only care about 1.16.5

[warm saddle]

are inventories indexed from 0 or 1?

[river oracle]

0

[chrome beacon]

?scheduling Read this

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[chrome beacon]

Also plugin is a reference to your main plugin class that extends JavaPlugin

[warm saddle]

is there a way to get custom player heads other than using HeadDatabaseAPI?

[chrome beacon]

Yes

[tender shard]

obviously. if that API would be the only way, then how would that API work?

[river oracle]

Yep. I use personally GameProfile and base64 strings, but you can also use Player UUIDs

[tall dragon]

they could be made all of those textures themself ? 😄

[river oracle]

take a look at mfnalex skull utils

[tender shard]

Create a new ItemStack. Cast the Meta to SkullMeta. use "setOwnerProfile" or "setOwningPlayer". A PlayerProfile can contain custom Textures

[tender shard]

or that, that's probably easier lol

https://github.com/JEFF-Media-GbR/JeffLib/blob/master/core/src/main/java/de/jeff_media/jefflib/SkullUtils.java

[fierce salmon]

does anyone know of any way to use both JDK and Spigot inside of one class

[river oracle]

what

[tall dragon]

that makes zero sense

[river oracle]

^

[fierce salmon]

For example, I want to be able to have a discord bot do something when a minecraft event takes place

[river oracle]

you mean

JDA

[tall dragon]

lol yea

jda

[fierce salmon]

oh

LMAO

[river oracle]

very different from the java JDK lol

[tall dragon]

well ye thats possible

a plugin is still a java program

[fierce salmon]

how can I implement both jda and bukkit listener to one class

[tender shard]

why would you ever want to do that?

that sounds like pretty stupid choice

anyway, where's the problem? make your class extend the JDA listener class thingy and implement Bukkit's Listener interface

no problem at all

just plain stupid

[fierce salmon]

alright

[tender shard]

you should definitely have separate classes for those

[fierce salmon]

Now I have one JDA class that checks for a message to be received in the discord server. How do I make it so once that happens, the variables are broadcasted through the server

Like how do I make the minecraft server issue a command once this event takes place

[tender shard]

simply call Bukkit.broadcastMessage or whatever you want to call from inside your JDA listener

[tardy delta]

listen for the jda event and dispatch a command using the spigot api

[fierce salmon]

oh u right u right

[tender shard]

for example

@Override
    public void onMessageReceived(@NotNull MessageReceivedEvent event) {
        if(event.getAuthor().isBot()) return;
        Bukkit.broadcastMessage(event.getMessage().getContentRaw());
    }

[fickle crater]

can someone help me with a simple question?

I am currently trying to spawn an npc, and my code so far is this:

MinecraftServer server = ((CraftServer) Bukkit.getServer()).getServer();
        WorldServer world = ((CraftWorld) Bukkit.getWorld(player.getWorld().getName())).getHandle();
        GameProfile gameProfile = new GameProfile(UUID.randomUUID(), ChatColor.GOLD + "" + ChatColor.BOLD + "Soldier");
        EntityPlayer npc = new EntityPlayer(server, world, gameProfile);```
And i am trying to set its location, but when i type npc.setLocation nothing shows up. What am i doing wrong?

[lethal python]

when my plugin teleports a player it says they moved too fast will this cause problems

[fierce salmon]

last thing, how do I register this class in my main file?

[tall dragon]

no

[lethal python]

epic

[tall dragon]

i suspect it also does not happen everytime

does it?

[lethal python]

it do b happening every time i think

[tall dragon]

server version?

[tawdry finch]

anyone know how i can like do a command that makes a custom world that i have as a file?

[lethal python]

paper somethin something

idk

i don't mind atm

i've got a location with a yaw/pitch and i want to translate that location 1 block along the view axis

how do i do that

[tall dragon]

anyway pretty sure u can just ignore that message

[lethal python]

how do i move a position's xyz 1 block along the location's view vector

[tall dragon]

soo u want to teleport the player forward 1 block?

[lethal python]

i just want to get the location of the block immediately in front of another location

[tawdry finch]

. can anyone help?

[lethal python]

no

[tall dragon]

wdym "in front"

[tender shard]

the JDA listener?

[humble tulip]

callen try block.getLocation.add(player.getLocation.getDirection.normalise.multiply(1.5)).getBlock

[lethal python]

thanks minion

[tender shard]

jda.addEventListener(new MessageListener());

[lethal python]

why 1.5?

[tawdry finch]

can someone point me in the right direction for this?

[humble tulip]

enough to reach the next block but not enought to reach the block past that

[lethal python]

ok thanks

[violet mauve]

As in import a world?

[humble tulip]

actually make it 1.8

because sqrt(3) is 1.73

@lethal python

[tawdry finch]

so i have a custom world and i want to run a command that like makes it load and kinda like multiverce the world gets added into the server

then another command that can tp ppl into that world!

if that makes sense

[fierce salmon]

I want to add the jda event to my main javaplugin file

[humble tulip]

if u dont have it as a file

u want the plugin to tell u that?

[violet mauve]

Use multivercore plugin? and use essentials or cmi to warp/tp ppl to that world

[tawdry finch]

no no

so

in my plugin

i want to have a world that you can "load" in then once its loaded it works like anyother world

does that makes sense?

[humble tulip]

https://www.spigotmc.org/threads/create-a-new-world.384473/

[tawdry finch]

im not trying to make a new world

im trying to make the plugin load a world that is a file

[humble tulip]

This loads one itnit exists as well

U can check if there is afolder woth the world name

[tawdry finch]

ahh okay

wait so how lol

[humble tulip]

And check if there is a level.dat file

https://www.w3schools.com/java/java_files.asp

[tawdry finch]

okay so

WorldCreator wc = new WorldCreator("world name"); << where "world name" is do i need to like add the look for file code there?

[tender shard]

you can simply put your world into the server directory. e.g. C:\MyServer\myCustomWorld

then just do Bukkit.createWorld("myCustomWorld")

then it loads your existing world or creates a new one if there is no folder called "myCustomWorld"

[tawdry finch]

ahh then it sees it as that

sweet

[tender shard]

exactly :3

[tawdry finch]

tysm!

[tender shard]

np

[tardy delta]

:o

[humble tulip]

Ur in the future man

[tender shard]

yay my vacation starts in 1 month and 30 minutes

[uneven fiber]

time traveler 😳

[fierce salmon]

how can I register a jda event inside of the main javaplugin file?

the jda event is from another class

[river oracle]

if it extends you can't

if it implements idk how touse JDA

[crimson scarab]

how can i make it possible for full hunger player to be able to eat

[fierce salmon]

eat what?

I think you need a mod for that

but idk

[tender shard]

I already told you - simply add an EventListener

jda.addEventListener(YourListenerInstance)

[fierce salmon]

it gave me an error

[15:13:41] [Server thread/ERROR]: Error occurred while enabling DiscSpigot v1 (Is it up to date?)

[tender shard]

bro

it tells you exactly the problem

your jda field is null because you never created any JDA instance

it literally says that

"this.jda" is null

with a stream or a regular for loop?

List<Player> players = getConfig().getStringList("players").stream().map(Bukkit::getPlayerExact).collect(Collectors.toList());

the list will contain "null" for every player who's not online

[tender shard]

bump anyone any ideas? :>

[humble tulip]

Filter

Map then filter

[tender shard]

no, that will a create a list like this

- CraftPlayer{name=mfnalex}

well depends what you want to store in the list lol

if you want to store their names, then yes, using getName() would be helpful lol

well what do you need it for? sometimes a name is better, sometimes a UUID. it depends on what you're trying to do at all

I have no idea what that is but it sounds like UUIDs are better for this

what is a tnt tag event?

[ivory flume]

Hello, i am trying to do this using NMS
Field field = Class.forName("net.minecraft.world.item.WrittenBookItem").getDeclaredField("MAX_PAGES");
but it says the class doesn't exist
java.lang.ClassNotFoundException: net.minecraft.world.item.WrittenBookItem
when it clearly does

[tawdry finch]

can someone point me in the right direction, Im trying to run a command that then spawns a portal ( neather portal ) That then tps a player into a custom world

[tender shard]

it doesn't clearly exist. that's just the mojang mapped name

the server doesn't use the mojang mappings

you should do WrittenBookItem.class, then the specialsource plugin translates it to the proper class name

[ivory flume]

so how would I go about doing it correctly then

and what about the field?

[tender shard]

you'll have to check the obfuscation map for that

[ivory flume]

won't that also cause some mapping error

[tender shard]

one second

[eternal oxide]

specialsource plugin for maven

[tender shard]

also wait whut

MAX_PAGES is a public field

no need to use reflection at all

[ivory flume]

i uh

want to change it

[tender shard]

oh okay

well two possibilities. both are dirty

[ivory flume]

no matter 🙂

[tender shard]

first:
WrittenBookItem.class.getDeclaredFields, loop over it until you found a field that's int and has a value of 100

that's your field

second way: hardcode the obfuscated field name and change it for every NMS version

[ivory flume]

the first one sounds better, thank you

[tender shard]

    public static Field getMaxPagesField() throws IllegalAccessException {
        for(Field field : WrittenBookItem.class.getDeclaredFields()) {
            if (field.getType().equals(Integer.TYPE) && ((int) field.get(null)) == 100) return field;
        }
        return null;
    }

Something like this. Haven't tested @ivory flume

alternatively you could get the field by it's index

it probably won't change anytime soon

public static Field getMaxPagesField() throws IllegalAccessException {
        return WrittenBookItem.class.getDeclaredFields()[4];
    }

this probably works too but it could break between updates. however the first method will break when the value isn't 100 anymore because you e.g. changed it yourself. so I'd get simply cache the result of the first method

[crude cobalt]

Give please advice. What is the best way to implement such a scale so that the colors change sequentially. Red - reduction of the scale, yellow - the normal state of the scale, green increase the scale. The scale depends on the value of the variable. I think it can be implemented with if , if else and server threads. Are there other options?

https://www.veed.io/view/db05a626-5479-40db-a93d-c7431f50313a?sharingWidget=true

[ivory flume]

oh wow thank you

[tender shard]

I'd probably do it like this

    private static final Field MAX_PAGES_FIELD;

    static {
        Field tmp = null;
        try {
            for(Field field : WrittenBookItem.class.getDeclaredFields()) {
                if (field.getType().equals(Integer.TYPE) && ((int) field.get(null)) == 100) {
                    tmp = field;
                    break;
                }
            }
        } catch (IllegalAccessException ex) {
            Bukkit.getLogger().warning("Couldn't get WrittenBook's MAX_PAGES field");
        }
        MAX_PAGES_FIELD = tmp;
    }

is there anyway to find out the <Class> of a Supplier<?> without actually calling get() on the supplier? I doubt there is

I basically want to get rid of the part I marked in red

[tawdry finch]

 Objects.requireNonNull(getCommand("Loadusd")).setExecutor(new Loadusd(this));``` Why does this give me a NPE error?

[tender shard]

because getCommand("Loadusd") is null

[tawdry finch]

it shouldnt be tho

how can i correct it?

[tender shard]

add that command to your plugin.yml

[tawdry finch]

it is lol

[tender shard]

?paste your plugin.yml pls

[undone axle]

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

[tawdry finch]

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

[tender shard]

okay then you're either editing the wrong plugin.yml or something

open your plugin .jar file with winrar and check the included plugin.yml

[tawdry finch]

nvm it works now

thats so weird

LOL

[tender shard]

what was the problem?

[tawdry finch]

honestly dont know

i just restarted the server

strange

[tender shard]

¯_(ツ)_/¯

huh isn't TypeToken part of Guava?

[tawdry finch]

?paste

[undone axle]

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

[tawdry finch]

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

can anyone tell me what this means lmao

ive been reading over it for like 5 mins now

[tender shard]

the player isn't online

you do something like Bukkit.getPlayer("notonline").teleport(...)

so Bukkit.getPlayer(...) returns null so you can't call teleport on it

[tawdry finch]

AHH

boolean p = Bukkit.getPlayer("notonline").teleport(loc); --- smtn like this lmao

[delicate lynx]

only teleport if getPlayer doesn't return null

[paper viper]

write a conditional to check if its null or not

and if it isnt just teleport

[tawdry finch]

errrrrr

so

i get what you mean

[tender shard]

Task:

Write a generic method to count the number of elements in a collection that have a specific property (for example, odd integers, prime numbers, palindromes).

Am I stupid or is the solution this simple? Am I misunderstanding the question?

    private static <T> int task1(Collection<T> collection, Predicate<T> predicate) {
        return (int) collection.stream().filter(predicate).count();
    }

[paper viper]

That should work

After all filter takes whatever is in the predicate and that is the property part ig

and you just count all the occurrences

[tender shard]

yeah of course, I mean, is that really all that is to the question? 😄

it seems way too easy

[paper viper]

Wheres the question from

lol

[tawdry finch]

        if () {
            p = p.isOnline() = false;
        } else {
            
        }```

not sure this is right LMAO

[tender shard]

oracle docs / exercises lol
https://docs.oracle.com/javase/tutorial/java/generics/QandE/generics-questions.html

[paper viper]

You want to first do a null check on Bukkit.getPlayer

[tender shard]

seems like all those questions are that easy

[paper viper]

oh lmfao

Player player = Bukkit.getPlayer(...);
if (player == null) { // player isn't online 
...
}

If the player returned is null, the player is not online

[tawdry finch]

        if (p == null) {
            sender.sendMessage(ChatColor.RED + "PLAYER OFFLINE");
        }
        else {
            
        }```

[crisp steeple]

did some testing, turns out you can but only if the supplier isnt a lambda
example:

public static void main(String[] args) {
        
        Supplier<String> sup1 = new Supplier<String>() {
            @Override
            public String get() {
                return "hello";
            }
        };

        Supplier<String> sup2 = () -> "test";
        
        System.out.println("Supplier 1: " + getClassOfSupplier(sup1)); // java.lang.String
        System.out.println("Supplier 2: " + getClassOfSupplier(sup2)); // java.lang.Object
    }

getClassOfSupplier method:

public static Class<?> getClassOfSupplier(Supplier<?> supplier) {
        try {
            Method supplyMethod = supplier.getClass().getMethod("get");
            return supplyMethod.getReturnType();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
            return null;
        }
    }

kind of odd

intellij is a liar

[tender shard]

oh lol interesting. however that doesn't help me because people can pass any supplier they want to my class :<

[tawdry finch]

ugh still getting that error lol

        if (p == null) {
            sender.sendMessage(ChatColor.RED + "PLAYER OFFLINE");
        }
        else {
          p.teleport(loc);
        }```

[crisp steeple]

yeah, dont think its possible with lambda since it doesnt seem like the function only has a generic return type

[tender shard]

yeah that's what I thought. then people will just have to live with the fact that I'll call their supplier once lol

[crude cobalt]

Hey, dudes, what you thing about this?

[tender shard]

I can't decide on what generic names to use. opinions?

public class MapDataType<M extends Map<K, V>, K, V> implements PersistentDataType<PersistentDataContainer, M> {
    // ...
}

public class MapDataType<MapT extends Map<KeyT, ValueT>, KeyT, ValueT> implements PersistentDataType<PersistentDataContainer, MapT> {
    // ...
}

public class MapDataType<MapType extends Map<KeyType, ValueType>, KeyType, ValueType> implements PersistentDataType<PersistentDataContainer, MapType> {
    // ...
}

Here I actually like the K,V thing most since you see that in lists all the time. But what about collections then? Just call those C,T?

public class CollectionDataType<C extends Collection<T>, T>  implements PersistentDataType<PersistentDataContainer, C> { ... }

it feels weird to call it C

[tall dragon]

C seems fine to me tbh

[tender shard]

C,T sounds like hospital lol

but yeah probably better than those overly verbose names

[ivory sleet]

by convention the first one looks best, but the last one is fine as well altho not conventional

[tender shard]

yeah I found those "naming schemes" by googling generics naming conventions and seems like every company does it totally different lol

google for example uses the second one but I don't like that at all

[ivory sleet]

ye

[tender shard]

I'll just back to the one letter things

[ivory sleet]

but google has weird style inspections

like srsly

[tender shard]

no idea, didn't really read anything about ther style things

[ivory sleet]

well for one they prefer 2 space indents to 4

[tender shard]

eew

[ivory sleet]

which is Ig fine, but almost everyone uses 4, thus it gets a bit unorthodox ye

[fierce salmon]

I have a question. I had to make a second main constructor for my jdk stuff inside of my java plugin. How do I register this inside of my onEnable function?

I will send code in a second

[tender shard]

jdk stuff?

[fierce salmon]

i was gonna send all of it

[tender shard]

yeah that's a good idea

?paste it pls

[undone axle]

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

[fierce salmon]

oh yeah

[tender shard]

I only see one constructor though?

btw

delete that link

I don't think the webhook url is supposed to be public?

[fierce salmon]

rly?

[tender shard]

I don't know

[fierce salmon]

oh well i guess ur right

[tender shard]

doesn't knowing that URL allow people to send stuff to your server?

[fierce salmon]

ye

its a test server so if they have it, it doesn't matter

[tender shard]

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

here's the same with link removed

okay so what exactly is the problem?

[fierce salmon]

theres the same error before with the this.jdk being null

i assume its because the constructor isnt registered or something

[tender shard]

?paste the full stacktrace again

[undone axle]

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

[fierce salmon]

hold up

i need to start my server again to get the error

[tender shard]

oki

[fierce salmon]

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

idk why it registered as coffee script

but here lol

[tender shard]

nope, can't be. the error isn't from the code you sent, but from another version

there is nothing in line 23 in your code

the code you sent isn't exactly the one that threw this error

[fierce salmon]

ok lemme upload my latest version and see where it is

[tender shard]

pls use exactly the code that you pasted

[fierce salmon]

i mustve made some changes since the last time i added the plugin to my server

?paste

[undone axle]

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

[fierce salmon]

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

[tender shard]

ah, that's a totally different error

[fierce salmon]

updated error

ye

[tender shard]

your error is now in GuildMessageReceived.java

send that class pls

[fierce salmon]

yes sir

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

[tender shard]

okay I guess your JDA is simply missing the proper GatewayIntents

it should at least have GatewayIntent.GUILD_MEMBERS

[paper viper]

assert user != null; dont use ide suggestions always pls 🙂

[tender shard]

        JDABuilder builder = JDABuilder.createDefault(confBotToken.getBotToken());
        builder.enableIntents(GatewayIntent.GUILD_MEMBERS); // Add this
        jda = builder.build();

add the GUILD_MEMBERS intent and see if that helps

[fierce salmon]

oh add this to my main?

[tender shard]

yes, where you build your JDA instance

[fierce salmon]

Cannot resolve method 'enableIntents' in 'JDA'

[tender shard]

instead of this: JDA jda = JDABuilder.createDefault("-").build();
do this: JDA jda = JDABuilder.createDefault("-",GatewayIntent.GUILD_MEMBERS).build();

[fierce salmon]

Oh ok

is this line still necessary?

[tender shard]

no

[fierce salmon]

ok

[tender shard]

that was an example from my code

[fierce salmon]

oh mb

[tender shard]

I have it on separate lines because my builder is a bit longer

[muted sand]

@tender shard your custom block pdc thing, what if i delete the block and place it somewhere else? Does that block contain the data?
What if I place a new block, does the new block get its own data or does it retain the data of the old block?

[fierce salmon]

didn't error 😄

[tender shard]

you have to take care about that yourself. I have a beta version that handles this for you but it's not public yet. Right now, my library simply provides one PDC per block LOCATION. If that block gets broken, you have to manually remove the data at that block location, etc, right now

[muted sand]

Oh alright. I'll keep that in mind! Thanks for this library!

[tender shard]

np & you're welcome!

as said, right now the data is totally indepent of the actual blocks so yeah. block place, block break, block moved by piston, won't affect the data at all

[muted sand]

oh and, as far as i know, tile entities have their own built in pdc correct?

[tender shard]

(and that will of course never change, even in future versions. but I'll add a method like "CustomBlockData.keepTrack()" or something and only then it will automatically take care of this, so it'll always be backwards compatible)

[tender shard]

yep

[muted sand]

.. what if i move that and place it somewhere else :D

[tender shard]

TileEntities, Entities, Chunks, Worlds and ItemMeta all have their own PDC

[tender shard]

it'll be gone

[muted sand]

Ah i see

[muted sand]

ohh

[tender shard]

the TileEntities "dies" and spawns a totally new Item with fresh ItemMeta

(although I am not 100% sure on that - you'll have to try it out if you want to be sure 😛 )

I never used any TileEntity's pdc

[vocal cloud]

Some tiles (shulkie bois) keep their data on break but most don't.

[tender shard]

but not the whole PDC data, right?

[muted sand]

onblockbreak
if shulker boi
clear pdc

[fierce salmon]

it says that the constructor that I made for jda isn't used

how do i register it in onEnable

[tender shard]

huh you know what? PDC on shulkerboxes doesn't work for me at all

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        Block block = ((Player)sender).getTargetBlockExact(20);
        TileState state = (TileState) block.getState();
        PersistentDataContainer pdc = state.getPersistentDataContainer();
        switch (args[0]) {
            case "get":
                if(pdc.has(new NamespacedKey(this, "test"),PersistentDataType.STRING)) {
                    sender.sendMessage("HAS CUSTOM DATA");
                } else {
                    sender.sendMessage("No custom data");
                }
                state.update();
                return true;
            case "set":
                pdc.set(new NamespacedKey(this, "test"), PersistentDataType.STRING, "asd");
                sender.sendMessage("Added custom data to " + state.toString());
                return true;
        }
        return false;
    }

Always prints "No custom data"

oh I am stupid

[humble tulip]

Because it behaves just like other tiles

[tender shard]

I updated the state in the wrong case

so I just checked, and TileEntities definitely lose the custom PDC data when the block gets broken @muted sand

(I simply used the TileState's PDC, so plain spigot)

[muted sand]

Oh

as expected i suppose
else you can't really stack items

[tender shard]

yeah I expected this but wasn't 100% sure

[muted sand]

Thank you for checking though!

[tender shard]

np

[ancient plank]

sometimes I forget if you can break a shulker with your fist and it scares me when I do it

[tender shard]

lol sure you can

they are soft and squishy

cute little shulker boxes

[humble tulip]

Lol someone loves shulkers

[next zinc]

Anyone know by chance why the mob isn't getting 1000 health?

        Main.createBossBar(fKnight, ChatColor.GOLD + "Fire Knight", BarColor.RED, BarStyle.SOLID);
        max_health.setBaseValue(1000);

        fKnight.setSize(5);
        
        
        
    }

[tender shard]

okay most of you people know my CustomBlockData class. Now I'm adding the function to keep track of data, e.g. automatically remove the data when a block gets broken, etc.

However, I wonder - probably most people do NOT want the custom data to also be added to the block's drop when the block gets broken. So I intented to make this configurable, using something like this:

public static void registerListener(Plugin plugin, CustomBlockDataOption... settings);

So when no options are given, it simply removes the block data on block break or when the block gets replaced with a new one. However, I am now wondering - how could I call the options that basically apply the broken block's data to the dropped item? I can't think of ANY proper name lmao

CustomBlockDataOption.APPLY_DATA_FROM_BLOCK_TO_DROP
and
CustomBlockDataOption.APPLY_DATA_FROM_ITEM_TO_PLACED_BLOCK
are both a bit overly verbose lol

[elfin tusk]

Does anyone know if there's a way to get all NamespacedKeys? I tried a few heavily scuffed ways of doing this but none worked which is why I'm wondering.

[tender shard]

from where?

[elfin tusk]

anything

[tender shard]

no

[elfin tusk]

datapacks, plugins, default

[tender shard]

you can basically create as many as you want

everytime, everywhere

the question is a bit like "how can I get all the strings"?

there are basically unlimited amounts of strings and namespacedkeys

[elfin tusk]

Can't you get the registered ones though?

[eternal oxide]

yes

[tender shard]

namespacedkeys do not get registered

what you can do is to get the namespacedkeys of all registered recipes

all registered biomes

etc etc

[elfin tusk]

So I could technically get a list of all of the advancements or something and get the keys that way?

I know the advancement iterator returns all of the advancements disregarding the namespacedkey

[tender shard]

yes

for example, for all registered recipes:

    public static List<NamespacedKey> getRecipeKeys() {
        List<NamespacedKey> list = new ArrayList<>();
        Bukkit.recipeIterator().forEachRemaining(recipe -> {
            if(recipe instanceof Keyed) {
                list.add(((Keyed)recipe).getKey());
            }
        });
        return list;
    }

[elfin tusk]

I will try it, thanks so much :D

[tender shard]

np 🙂

https://paste.md-5.net/esozixapom.xml I love enums

[tender shard]

no ideas? :<

[elfin tusk]

I do not know your CustomBlockData class :(

[tender shard]

it provides a PersistentDataContainer for every block

so basically a library to store data in blocks

[elfin tusk]

my ideas are longer than yours 😅

[tender shard]

😄

[elfin tusk]

Just looked up another way to say sentence generator....

apply information from square to drop

maybe APPLY_FROM_ITEM and APPLY_FROM_BLOCK?

although it is pretty difficult to piece together the message you want to get across

[tender shard]

yeah that's definitely better lol

    private static final PersistentDataType<?,?>[] PRIMITIVE_DATA_TYPES = new PersistentDataType<?,?>[] {
            PersistentDataType.BYTE,
            PersistentDataType.SHORT,
            PersistentDataType.INTEGER,
            PersistentDataType.LONG,
            PersistentDataType.FLOAT,
            PersistentDataType.DOUBLE,
            PersistentDataType.STRING,
            PersistentDataType.BYTE_ARRAY,
            PersistentDataType.INTEGER_ARRAY,
            PersistentDataType.LONG_ARRAY,
            PersistentDataType.TAG_CONTAINER_ARRAY,
            PersistentDataType.TAG_CONTAINER
    };

    public static PersistentDataType<?,?> getDataType(PersistentDataContainer pdc, NamespacedKey key) {
        for(PersistentDataType<?,?> dataType : PRIMITIVE_DATA_TYPES) {
            if(pdc.has(key, dataType)) return dataType;
        }
        return null;
    }

This should definitely be builtin to spigot

[elfin tusk]

So I have run into a slight problem with my code. I probably should have been more clear last time, but I am trying to get an advancement and delete it without having to specify its namespace. I have the code that you kindly gave me in order to get the namespacedkeys, but how would I get the advancements from those without going through them one by one?

[elfin tusk]

agreed

[tender shard]

well if you don't have the key, how would you actually identify the advancement to delete?

I mean you must at least have ONE information about it

[elfin tusk]

I have the key from the code you gave to me which works but I just need to use that key to get the advancement which won't work.

[tender shard]

hm I still don't really understand

is there any specific advancement you want to delete?

btw I don't think you can remove advancements at all, at least not without NMS

Bukkit.advancementIterator returns an UnmodifiableIterator

[elfin tusk]

You can with Bukkit.getUnsafe, although it is depreciated

[tender shard]

oh okay

good to know

TIL

I mean Advancements basically only have a List<String> and a NamespacedKey

[elfin tusk]

I want to delete any advancement from a datapack or something but the keys for each of these advancements would be different. I have the code to get the namespacedkey so I used a for loop in order to go through each of these keys and check which ones have it, but for some reason it doesn't work.

So theoretically could I get a list of all of the advancements and get the value of that advancement in the list then delete it using that?

I should probably try it 1 moment

[fierce salmon]

@tender shard how would I register the main constructor I made for jda into the onEnable method of the Java Plugin?

[tender shard]

if you only want to delete all non-vanilla advancements, you can simply filter them by namespace. example:

    public static List<NamespacedKey> getAllNonVanillaAdvancements() {
        List<NamespacedKey> list = new ArrayList<>();
        Bukkit.advancementIterator().forEachRemaining(advancement -> list.add(advancement.getKey()));
        return list.stream().filter(key -> !key.getNamespace().equals(NamespacedKey.MINECRAFT)).collect(Collectors.toList());
    }

[tender shard]

you don't and you don't have to

JDA has nothing to do with your main class constructor or anything

[fierce salmon]

But it doesn't seem to be running

[tender shard]

yes, your empty Constructor will never be called

you shouldn't do it there anyway

you should instantiate and build your JDA in your onEnable directly

no need to create a new useless constructor

[muted sand]

@tender shard sorry for another mention
But your PDC is for the location of the block right?
I can get the BlockBreakEvent -> event.getBlock() -> pdc stuff -> clear it?

[tender shard]

public class MyPlugin extends JavaPlugin {
  JDA jda;

  public void onEnable() {
    jda = JDABuilder.createDefault(...).build();
   }
}

[tender shard]

exactly

although I'm currently working on doing this automatically

[muted sand]

alrighty!

[tender shard]

it's a pain in the ass though to handle all events lol

[elfin tusk]

So when using NamespacedKey.fromString() do you have to mention the namespacedkey or the actual advancement as well. I am using Bukkit.getAdvancement(NamespacedKey.fromString()) so in fromString() do I put fromString("namespace:advancement/name") or fromString("advancement/name")

[tender shard]

let me check

?jd-s

[undone axle]

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

[tender shard]

it definitely doesn't hurt to add the namespace

you also have to provide it for custom stuff

but I think you can omit it for minecraft: stuff

[elfin tusk]

alright thank you

[tender shard]

you HAVE to provide the full name

datapack:advancements/someadvancement

if you don't, it creates a minecraft default key

[elfin tusk]

ah okay

let's hope this works

[tender shard]

ugh

took me two minutes to find the actual error

quite misleading error message

[vocal cloud]

Nice semi

[tender shard]

yeah fuck intelliJ

why didn't it just say " a semicolon doesn't belong there" lol

[vocal cloud]

It looks to me like it thinks you ended the constructor early

[worldly ingot]

What an absolute Chad.

1. Creates a new List and adds to it all values of an Iterator
2. Proceeds to filter that list with a Stream
3. Creates a new List to hold it

https://tenor.com/view/clap-clapping-applause-applaud-cheerleader-gif-12591824

    public static List<NamespacedKey> getAllNonVanillaAdvancements() {
        List<NamespacedKey> keys = new ArrayList<>();

        Bukkit.advancementIterator().forEachRemaining(advancement -> {
            NamespacedKey key = advancement.getKey();
            if (key.getNamespace().equals(NamespacedKey.MINECRAFT)) {
                keys.add(key);
            }
        });

        return keys;
    }```

[tender shard]

hm I am confused

does anyone know why lines 120 and/or 125 always throw a StackOverflowException whenever I move a piston? https://github.com/JEFF-Media-GbR/CustomBlockData/blob/e199da4cb193fc710eae9a3d858821177ebdfeea/src/main/java/com/jeff_media/customblockdata/internal/CustomBlockDataListener.java#L120

nvm. I forgot that I only recompiled the library, but the plugin used to test it >.<

@muted sand I think I can release this tomorrow, seems to be working fine 🙂 (the "keep track" of block data in mined blocks, moved blocks, exploded blocks, etc thingy)

it can be enabled with CustomBlockData.registerListener(plugin);

[muted sand]

Wooo!!!

[tender shard]

:3

is there a way to automatically add links to javadocs in intellij?

E.g. when I mention "NamespacedKey" in the javadocs, I need a shortcut that automatically turns it into {@link NamespacedKey}

[minor vapor]

No, if your write the documentation correctly using the @link tag, it will make an href to the class you linked

[willow gull]

Anyone know how to fix bootup time for 1.16+, we are making a huge mini game server and we are trying to find someone who can efficiently fix this problem. The CPU usage on my dedi spikes to around 82% when starting a 1.18.2 Paper server, I tried 1.17 and stuff too, it's fine on 1.12.2 and below, just newer versions have issues. The CPU is Ryzen 7 3800X.

[tender shard]

I know. But that's the problem

I don't wanna type {@half zephyr all the time

sry for ping lol

[muted sand]

"hi"

yo wtf 0420 discrim without nitro

[tender shard]

I want IntelliJ to automatically insert the link tags @minor vapor

[dense geyser]

with a name like that, its semi deserved

[tender shard]

kinda lol

[minor vapor]

I don't believe that's possible. What's wrong with typing the proper documentation tags?

[tender shard]

that I write way too much documentation and I just think that it should be able to do it automatically 😄

[minor vapor]

The IDE can't do everything on it's own

[tender shard]

even in this tiny excerpt there's least 4 links missing and I don't wanna go through everything again all the time to add those links ><

[ivory flume]

how would I change the link it sends you in the demo screen?https://media.discordapp.net/attachments/497832896586055721/981405936663011388/2022-05-31_23.54.32.png?width=1175&height=643

[minor vapor]

If you don't want to use the @link tag multiple times for a single comment, you can use the @see tag instead

However, it still requires you to type it at least once

[tender shard]

yeah I know but I'd rather have a link inside the text itself. but yeah I'll just go through everything again tomorrow lol

[hasty prawn]

"CustomBockData", might wanna fix

[dense geyser]

Saving files in databases

[tender shard]

yeah my L key is stuck sometimes

I'm smoking too much in front of the PC and then ash goes into the keyboard lol

anyway is there any way I can use the parametrized version of PersistentDataType here?

    public static PersistentDataType<?, ?> getDataType(PersistentDataContainer pdc, NamespacedKey key) {
        for (PersistentDataType<?, ?> dataType : PRIMITIVE_DATA_TYPES) {
            if (pdc.has(key, dataType)) return dataType;
        }
        return null;
    }

    public void copyTo(Block block, Plugin plugin) {
        CustomBlockData newCbd = new CustomBlockData(block, plugin);
        getKeys().forEach(key -> {
            PersistentDataType dataType = getDataType(this, key); // <----- HERE
            if (dataType == null) return;
            newCbd.set(key, dataType, get(key, dataType));
        });
    }

in the line where I added the comment

it works fine like this but yeah it's the raw type

when I add <?,?> to the dataType variable, javac isn't happy anymore

I basically need something like ?,? but at the same time tell javac that the second ? is definitely the same type as the first ?

[quaint mantle]

I've been trying to setup action bars for my plugin and every thread online says to do something like this but it always tells me Cannot resolve method 'sendMessage(ChatMessageType, TextComponent)'

        TextComponent text = new TextComponent(message);
        sender.spigot().sendMessage(ChatMessageType.ACTION_BAR, text));
    }
}

nevermind i just had to cast sender to a Player class

[muted sand]

If I were to use CompleteableFutures, should I use the async method within them, or still invoke Bukkit's async thread to call the Future method?

[humble tulip]

Honestly I'm not sure

I was told here that bukkits asymc tasks can still run oj the main thread

So maybe completeAsync is the way to go for especially heavy stuff

[muted sand]

oh-

[muted sand]

okay!

    public static CompletableFuture<Boolean> postWebhook(String message) {
        CompletableFuture<Boolean> future = new CompletableFuture<>();
        future.completeAsync(() -> {
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                throw new RuntimeException(e);
            }
            System.out.println(message);
            future.complete(true);
            return true;
        });
        return future;
    }

I think I am doing this correctly? Intelij just told me to addd that return true; tho-
i could just return null

[kindred valley]

Is it possible we can create a client and that client will install forge mods automatically?

[muted sand]

i mean isn't that forge modding / custom client modding

doubt the server can access the client's filesystem

[humble tulip]

You don't need to call future.complete

Just return the value

[ornate patio]

how can i get NMS to work with Maven?

[humble tulip]

The code in the lambda method thing is what is run async to get your result

[muted sand]

oh

[humble tulip]

So just return the result

[muted sand]

im calling it as-

    @EventHandler
    public void onInventoryClick(InventoryClickEvent event) {
        CompletableFuture<Boolean> player1 = postWebhook("aaaaaa");
        event.getWhoClicked().sendMessage(player1.toString());
}
``` (ignore the event im using for this)

[humble tulip]

Yes

That's not the way to use it

[muted sand]

oh

what would the proper method be then?
and why can't i use it like that?

[humble tulip]

U need to call player1.whencomplete

So u can run code when it's finished getting thebvalue

[kindred valley]

Yeah the launcher is gonna run the client but that forge will be automatically installed and the mods too

[muted sand]

oh..
i was trying to avoid nested code

[ornate patio]

bump

[humble tulip]

Code is gonna have to be nested somewhere

[muted sand]

:( oh well

[humble tulip]

You can have a class that handles all of that though

[muted sand]

oh, alrighty! thank you!!

[little panther]

do anyone know how to use custom items for a recipe?

[humble tulip]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/RecipeChoice.ExactChoice.html

[little panther]

https://i.imgur.com/t9XAJdV.png Im guessing i did it right then?

[humble tulip]

I think nit because you casted?

New ExactChoice(IronStick)

[harsh totem]

I tried to do this and nothing happened

    public void SpawnMob(RaidEvent event){
        if (event.getRaid().getBadOmenLevel() >= 5){
            Illusioner mob = (Illusioner) event.getWorld().spawnEntity(event.getRaid().getLocation(), EntityType.ILLUSIONER);
            event.getRaid().getRaiders().add(mob);
        }
    }```

[little panther]

it was the recommandation my IDE gave me

ill try this then

[humble tulip]

Because you passed an itemstack

[little panther]

yea, thats fair

[humble tulip]

Ide realized that it wasnt a recipechoice and assumed u were right

So it told you to cast

[little panther]

yea

[humble tulip]

Well see if your listener is registered and print the badomenlevel

[little panther]

https://i.imgur.com/qFF1Nce.png Can someone help me understand why this doesnt work btw? Idk if im blind or just did something wrong when i tested

[humble tulip]

What do u see in console?

So i can see which ifs are executed

[harsh totem]

it says this when I reload the server

org.bukkit.plugin.IllegalPluginAccessException: Unable to find handler list for event org.bukkit.event.world.WorldEvent. Static getHandlerList method required!```

[humble tulip]

You don't have a static getHandlerList method

Wait

[harsh totem]

wdym

[humble tulip]

That's a bukkit event

Wtf

[harsh totem]

am

how does that even work

[humble tulip]

Idek

[harsh totem]

the IDE doesn't show any error

lol

org.bukkit.event.EventException: null```
```Caused by: java.lang.UnsupportedOperationException```

[sand frost]

Its not recommended to reload the server. Restart is always better

[tardy delta]

Method names start with a lowercase char

[little panther]

https://i.imgur.com/QRXa07Z.png this happens now lol

[humble tulip]

Symbol doesn't appear in shape

Let me see your code

[little panther]

can you see what call causes it? Cuz ive changed a few things since last time i tested

[humble tulip]

Let me see the recipe

[sand frost]

createUmbrella is the problem

[little panther]

https://pastebin.com/iyggFfDZ

im guessing its the recipe then

[humble tulip]

You're setting s twice

And there is no C

[little panther]

oh right

took an old template 😄

[sand frost]

Also there is a P

[little panther]

this is still not working tho

[humble tulip]

Did u replace C with P

And remove one setting of S

[little panther]

thats fixed, the plugin is working now

[hybrid spoke]

I C U P

[little panther]

but that event is not starting at all

[humble tulip]

Did u register the listener

[little panther]

yupp, it should be atleast

[tacit dagger]

how i can get the circled config?

[humble tulip]

just tes

u wanna get like base?

[tacit dagger]

actually i want to get all of this list

not only "tes"

[crimson terrace]

whats the key you have the list under (if any)

[humble tulip]

Ohh well just do just do getConfig.getKeys(false)

[thorny dawn]

it only displays scores from 3-0 while i have others registered aswell

[hybrid spoke]

probably because you have duplicates

[thorny dawn]

duplicates of what

[hybrid spoke]

scores

[thorny dawn]

score names?

oh

i didnt know it was a thing
