The reason is that local variables reside on stack and is visible only in local method context, unlike instance variables which resides on heap and has scope throughout the program.

no idea if that's a good explanation but it's the only explanation I found

[smoky oak]

so if i were to make them into variables of the object they would be null?

[tender shard]

yes

[smoky oak]

k

[tender shard]

and primitives will be 0, or false if a boolean

[smoky oak]

kinda sorta null

[humble tulip]

What are they then if not null?

[smoky oak]

they are 'nothing'

apparantly thats different from null

refer to alex explanation above i guess

[humble tulip]

Btw don't u wanna separate right wing vs leftwing?

[smoky oak]

im still working on that

[humble tulip]

https://math.stackexchange.com/questions/274712/calculate-on-which-side-of-a-straight-line-is-a-given-point-located

Check first answer

The line will be the direction of the location of the dragon

[smoky oak]

eh i got a completely different issue right now

see my plan was to part the dragon

part here part there

but apparantly you cant remove single parts of the dragon

[humble tulip]

rio

Rip*

U might have to use nms then

[smoky oak]

welp im an idiot

[tender shard]

you still can't remove parts of that

[smoky oak]

darn

can i somehow trick the game into applying potion effects to dragon parts

[tender shard]

I think you can only apply potions to LivingEntities. ComplexEntityPart is not a livingentity

[smoky oak]

yeah i suspected as much

damn

so its a modded thing

unless i want to mess with custom block models

which i really dont have the energy for

[limpid bronze]

Hey, I want to filter all declared fields in a interface class that have the type Tag<Material> and I don't know how to do it, here my possible idea:
Arrays.stream(Tag.class.getDeclaredFields()).filter(tag -> //verify if tag has Tag<Material> type)
Here's the interface class: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Tag.html#PLANKS

[tender shard]

you can't

the generic type gets erased at compile time

in the bytecode, those fields will just be "Tag" and not "Tag<Material>"

[smoky oak]

is the dragon animation handled by the server or the client?

[limpid bronze]

oh, thanks

[tender shard]

you could only get the Tag, then do getValues() and check if any of those values is instanceof Material

[limpid bronze]

Okay thanks

[tender shard]

e.g. like this (haven't tested it though)

        Set<Tag<Material>> materialTags = Arrays.stream(Tag.class.getDeclaredFields()).filter(field -> {
            try {
                return ((Tag<?>)field.get(null)).getValues().iterator().next() instanceof Material;
            } catch (Exception e) {
                return false;
            }
        }).map(field -> {
            try {
                return (Tag<Material>) field.get(null);
            } catch (Exception e) {
                return null;
            }
        }).collect(Collectors.toSet());

[limpid bronze]

Thank you very much

[eternal oxide]

Why are you trying to list all members?

[ebon topaz]

is it possible to make a plugin that stops endermen from teleporting onto bottom half slabs?

[eternal oxide]

Without messing with the AI you could listen to the teleport event and cancel it for any Endermen where the location below them is half slabs. https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityTeleportEvent.html

[brave goblet]

Is it possible to have a resource pack with a custom sound file and make the plugin play that sound?

[earnest forum]

no

u can only modify existing sounds

[brave goblet]

Is it possible to make a new sound id or sum so i don't have to replace current sounds?

Like how does ItemAdder do it and i seen some resource pack in 1.12 add a new song without replacing anything but not sure how it works

[eternal oxide]

p.playSound(p.getLocation(), "name.of.sound.has.set.in.resourcepack", 20F, 20F); I believe

[brave goblet]

ah ok so name of sounds would be the file name?

like this minecraft:ambient.customsong.1 or just ambient.customsong.1

ill just watch a yt :P and look at docs

[eternal oxide]

[brave goblet]

thanks! much appreciated

[glossy venture]

is there a way to load classes which can be accessed between plugins?
because you can access other plugins from plugins so i wondered why this was not working.
im currently using

URLClassLoader ucl = new URLClassLoader(
        new URL[] { pkgCUrl },
        JavaPluginLoader.class.getClassLoader()
);

// ...

Class.forName("c.pkg.PackageC", true, ucl)
        .getMethod("loadPackage")
        .invoke(null);
``` where `pkgCUrl` is a url to a jar file

accessing this from plugin B, throws java.lang.NoClassDefFoundError: c/pkg/PackageC

^ in B

[wary harness]

any one could tell how to use boss bars

[wary harness]

I got Tab plugin which uses boss bar already

I want to be sure my plugin is the one which takes

first bar positon

so like multiple boss bars

is it possible to know at which positon is my boss bar

is there any good BossBar lib

[golden turret]

maybe if you use some reflection and craftbukkit

[wary harness]

So psitening of my boss bar is important

[golden turret]

but i think it is handled by the client

[wary harness]

Because I am trying to use boss bar to display custom gui over custom font

and then all goes in trash bin if boss bar positon is in wrong place

[golden turret]

as i said, it may be handled by the client

so you can control it

one thing you could do is to use reflection and craftbukkit and clear all bossbars and display all of them in the order you want

because the bossbar dont have a priority system

[agile anvil]

Why using multiple boss bars ? Just using the action bar is way enough

[mortal hare]

Why someone would make bossbar api in 2022

[daring egret]

Why is a string variable I set null?

[mortal hare]

Bukkit bossbar api exists since 1.9 (2016)

[mortal hare]

Dude. You Are Genius.

And i know how to solve that problem

[golden turret]

code

[mortal hare]

Use negative spaces font made by AmberWat on github

And it would allow you to position the font without using multiple bossbar

[daring egret]

public class StaffCommand implements CommandExecutor {
    
    String msg;
    
    @Override
    public boolean onCommand(@NotNull CommandSender sender, @NotNull Command command, @NotNull String label, @NotNull String[] args) {

        if(!(sender instanceof Player)) return false;
            Player player = (Player) sender;
        if(!sender.hasPermission("lukaessentials.staffgui")) {
            player.sendMessage(ChatColor.RED + "You can't do that!!");
        }
        
        msg = args[1];

        //GUI CREATION
        Inventory staffGUI = Bukkit.createInventory(player, 54, ChatColor.RED + "Staff Menu");

        //GUI ITEMS
        ItemStack playerHead = new ItemStack(Material.PLAYER_HEAD);
        SkullMeta playerHeadMeta = p;
        
        player.sendMessage();
        return false;
    }
}
``` @golden turret

[mortal hare]

Also ascent in font.json can help you vertical align it

[golden turret]

what is null there

[daring egret]

String msg

also player.sendMessage(); is player.sendMessage(msg);

[golden turret]

ok

do you know java?

[daring egret]

not really lol

[golden turret]

🤔

[daring egret]

i'm still learning

[golden turret]

?learnjava

[undone axle]

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

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• 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.

[golden turret]

ok

first you need to check if the lenght of the args is what you want

/command args0 agrs1 args2...

[daring egret]

yeah i know, i just quickly recreated it for you because it's my friends problem not mine

and he did chec

[golden turret]

/command args0, args.length = 1
/command args0 args1, args.length = 2

[golden turret]

here you are getting the args1

[daring egret]

no

[golden turret]

and probably you are typing /command or /command agrs0

array indexes starts in 0

so 1 is the 2nd index

[daring egret]

I know that bro

i just quickly recreated my friends issue

package ajo_29.testplugin.testplugin.commands;

        if (!(sender instanceof Player)) return false;
        Player plr = (Player) sender;
        if (args.length == 3) {
            Player target = Bukkit.getPlayerExact(args[0]);
            if (args[2] == "prefix") {
                plr.sendMessage("ur bad");
                prefi = args[2];
            }
        }
        return false;
    }

    @EventHandler
    public void onPlayerChat(PlayerChatEvent event) {

        Player plr = event.getPlayer();
        String msg = event.getMessage();

        event.setCancelled(true);

        Bukkit.broadcastMessage(ChatColor.translateAlternateColorCodes('&', prefi  + " " + plr.getDisplayName() + " " + msg));
    }
}```

this is my friends code

he sent it to me

[golden turret]

aaa

[daring egret]

String prefi; is null

[golden turret]

now you sent the error

he is not initializing prefix nor suffix

[daring egret]

he's not?

[golden turret]

actually he is

[daring egret]

lol

[golden turret]

but not suffix

[daring egret]

he's not using suffix yet

[golden turret]

ok

first, use AsyncPlayerChatEvent, it does not fix it but this is a better event

[daring egret]

okay

we changed it to PlayerChatEvent to try to fix

[golden turret]

2nd, probably he is chatting before running the command

so the prefix will be null

as he only initializes the variable after running the command

[daring egret]

but it's null after running the command

[golden turret]

does the command even work?

[daring egret]

yes

[golden turret]

just a question

[daring egret]

everything works but the variable is not being set

[golden turret]

im not seeing any agrs[1] there

[daring egret]

and?

[proper saffron]

mf

wizardly

[golden turret]

could you send me the full command he is typing pls

[proper saffron]

ur not helping

i found the problem

its nowhere near what u were saying

thanks for the help <3

[daring egret]

oh

[golden turret]

🤔

[daring egret]

he's typing /customchat dein0man prefix TEST

and TEST is null

[golden turret]

well, in the code you gave there, i did not see any args[1]

[proper saffron]

yeah because we tried that

[daring egret]

why does it need that though

[proper saffron]

that didnt work

[golden turret]

because what you were doing is

[daring egret]

Ohh no i get it

[proper saffron]

is

[daring egret]

we changed to args[2] to see if it worked

[golden turret]

/command args0 args1 args2 but the args1 wasnt being used

[daring egret]

i know

cause in that code we changed it

to see if that was the issue

[proper saffron]

yeah but args1 didnt work at first

[golden turret]

ok

could you send me the current code

[daring egret]

sure

[proper saffron]

[golden turret]

is that working now?

[proper saffron]

no

[golden turret]

ok

could you test your code and print the console log pls

[proper saffron]

mk

[20:43:27 INFO]: null dein0man a```

[golden turret]

the command is working right?

sending the message

[proper saffron]

yeah but it doesnt set the prefix

[golden turret]

aaaa

ik

ik

just to be sure

print the code you are using to register the command and listener

[proper saffron]

    public void onEnable() {
        getServer().getPluginManager().registerEvents(new customchat(), this);
        getCommand("customchat").setExecutor(new customchat());
    }```

this one?

[golden turret]

yea

exactly what i tought

the variables you created are only for 1 object

so

[tardy delta]

Conventions pls

[golden turret]

you creating 2 objects

and updating the variable for only 1 of the objects

a fix for taht would be using only 1 object

by using customchat chat = new customchat();

and passing chat in the setExecutor and registerEvents

[daring egret]

OHH

YOUR A GENIUS

(if it works)

[proper saffron]

@daring egret "i know java" my ass

[daring egret]

?

[golden turret]

or you can set the variables as static

or you can use oop

[golden turret]

that is an advanced option

and a better one

once you learn oop and how to apply it, back to your plugin and use oop

[daring egret]

what is oop

i'm kinda stupid alright

[golden turret]

object oriented programming

[proper saffron]

[20:49:39 INFO]: TEST dein0man TextComponentImpl{content="hello there", style=StyleImpl{obfuscated=not_set, bold=not_set, strikethrough=not_set, underlined=not_set, italic=not_set, color=null, clickEvent=null, hoverEvent=null, insertion=null, font=null}, children=[]}

[daring egret]

oh

[golden turret]

you should use event.setFormat

it is better

[daring egret]

oh

u right

WizardlyBump17

how do u access the message as a raw string

because the only thing close is event.message() which doesn't work

[proper saffron]

man

[golden turret]

event.getMessage?

[proper saffron]

setFormat is PlayerChatEvent

AsyncChatEvent or not?

[daring egret]

doesn't exist in AsyncChatEvent

[golden turret]

it does

[undone axle]

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

[golden turret]

?jd-s

[proper saffron]

man u good?

it doesnt

[daring egret]

but then why is it red and not auto-correct

[daring egret]

but it doesn't work

[proper saffron]

thats not for asyncchatevent

[golden turret]

which version are using

[daring egret]

@golden turret it probably doesn't exist in AsyncChatEvent?

[quaint mantle]

how do I send a string message as a player?

[daring egret]

1.19

[golden turret]

use AsyncPlayerChatEvent

[proper saffron]

you said async chat event

we've been running around in circles

[daring egret]

this hurts lmao

[golden turret]

print the event.getMessage on the ide

[proper saffron]

nah we got it now

it workin

[daring egret]

thanks man

[golden turret]

👍

event.setFormat(prefix + " %s: %s"); is a better option btw

[daring egret]

ohg

thanks!

[quaint mantle]

I took message string, edited my targeted elements, now how do I send this string so it appears as if the player sent it?

[grand magnet]

Can someone please help me with this? I want to send a message to every player who is on the server, but not to myself. My code looks like this so far. for(Player all : Bukkit.getOnlinePlayers()) { all.sendMessage(new String(message)); }

[lost matrix]

You can let the player write something in chat

[quaint mantle]

using what function

[lost matrix]

Bukkit has a broadcast method

[lost matrix]

    String message = "Hi to everyone";
    Bukkit.broadcastMessage(message);

[grand magnet]

I know that but then the message goes to me anyway and I don't want that.

[tardy delta]

Then do a for loop and skip yourself

[grand magnet]

How does it

[tardy delta]

Learnjava moment

Just continue if the player has your uuid

[lost matrix]

    Player player = ...;
    player.chat("Im dirt.");

[grand magnet]

The message should go to all players who are on the server, just not to the sender

[lost matrix]

Then do that. create a for loop with a conditional statement (if) in it

[grand magnet]

How does it?

[lost matrix]

How does it what?

And what is "it" referring to?

[grand magnet]

What do I have to write in the If query

[tardy delta]

Smh

For player player : all player
If not you then send message

[lost matrix]

(pseudo code)

For player in Bukkit.getOnlinePlayers()
  If ( player is not sender )
    player.sendMessage(message)
  EndIf
EndFor

[tardy delta]

Continue 😋

[glossy venture]

anyon e?

does anyonem lkmwoiw

[lost matrix]

Are you depending on the other class?

[twilit roost]

any way to make this?

[glossy venture]

i have one plugin that loads the class, and i want to make it usable from another one

[grand magnet]

Thank you very much

[lost matrix]

Then do that. I dont understand what the problem is. They are both on the same jvm so you
can reflectively access every class of every plugin.

[glossy venture]

it does look like it

it doesnt work

and i dont want to have to use reflection

[lost matrix]

What is the actual purpose of this?

[glossy venture]

the point is dyanmically loading modules for other plugins

and i know that plugins can access other plugins

[lost matrix]

Who is loading the modules?

So plugin A loads "modules" from plugin B

[glossy venture]

no i have
loader plugin A

user plugin B

and package C

A is supposed to load C, and then B is supposed to be able to use C

no reflection

[lost matrix]

Ooh... that will be very hard because every plugin has its own classloader

[glossy venture]

yeah but they are all parented to JavaPluginLoader.class.getClassLoader()

[twilit roost]

bump

[frosty tinsel]

Yes

[twilit roost]

and do you know how?

[frosty tinsel]

Probably packets

Don't think there's an API for that

[lost matrix]

Did you make sure that plugin A loads package C after plugin B is loaded?

[glossy venture]

A is set to load: STARTUP

and the loading happens in onLoad

so its basically the first thing that happens

[lost matrix]

So even before B has any chance to load?

[glossy venture]

bruh i gtg now

yeah

i think now

[tacit dagger]

why isn't setInvisible imported into my plugin? I'm quite confused about the import

[lost matrix]

What version?

[lost matrix]

Do you have vault in your pom?

[tacit dagger]

i add the vault on plugin lib

[tacit dagger]

1.16.2

[tender shard]

1.16.2?!

LivingEntity#setInivisible was added in 1.16.3

[tacit dagger]

ahh yeah, i just deleted some files and it made some import from my plugin error instantly

[tender shard]

if you really want to use 1.16.2 for whatever reason, you have to set the flag on the NMS entity. There's a field called "persistentInvisibility" (in 1.16, the name will be different) and then set the shared flag 5 to true

[tacit dagger]

but how do i can change it from 1.16.2 to 1.16.5 ?

[tender shard]

are you using maven?

[tacit dagger]

yep

[tender shard]

then change the version of your spigot dependency from 1.16.2-R0.1-SNAPSHOT to 1.16.5-R0.1-SNAPSHOT

[tacit dagger]

its already 1.16.5, what

[daring egret]

punishMenu.setItem(0, placeHolder); i know this is a stupid question but how do i set more than 1 slot with the same item? I've tried creating arrays and things

[lost matrix]

for loop and and set the same item on different indices

[daring egret]

ohh

you right

i didn't think of that lmao

[twilit roost]

Does anyone know a good site for Retexturing Skull with higher resolutions?

[tacit dagger]

alr its fixed now, i need to change the .iml to 1.16.5 too

thank you

[tender shard]

actually you don't need that, unless you manually added spigot as dependency, which you should never do when using maven

[tacit dagger]

ahh i see, im still dumb on maven and importing like that

[limber marten]

Hey! I'm trying to create a plot with my own custom generator in a new void world. Ideally i would like a method like generatePlot(int chunkX, int chunkZ) which generates a plot of 4x4 chunks at the given chunks coordinates (chunkX and chunkZ) using my own ChunkGenerator. Rn, i just finished created my ChunkGenerator and i'm wondering how can i use it to create my plot?
My ChunkGenerator (screenshot) : https://media.discordapp.net/attachments/600329318559776781/991671068362280970/2022-06-29_13.45.28.png?width=1276&height=671
What i want (this is something i built as an example) : https://cdn.discordapp.com/attachments/600329318559776781/991460006748758076/2022-06-28_23.42.11.png

Maybe i can use ChunkGenerator#generateNoise(WorldInfo, Random, int, int, ChunkData) manually, but i don't know how to do that.

[desert tinsel]

How to insert a string array directly in method?

[limber marten]

Arrays.asList() ?

[heady spruce]

[desert tinsel]

Incompatible types. Found: 'java.util.List<java.lang.String>', required: 'java.lang.String[]'

[limber marten]

String[] str = {"lore1", "lore2"};

[lost matrix]

Most games (minecraft included) use a noise algorithm. I suggest OpenSimplexNoise. It generates a double[][] (range 0.0 - 1.0) which you can tune and use as a height map

[lost matrix]

You cant use BungeeCord features on Spigot. Those are two completely different applications.

[limber marten]

I already created and used a simplex noise algorithm. The issue is to use my ChunkGenerator manually

[desert tinsel]

Array initializer is not allowed here

error

[lost matrix]

Where is this method from? It should use varargs here. Looks like a design flaw.

[desert tinsel]

actually it's my method

[heady spruce]

is there still a way to use them?

[lost matrix]

Implement the
ChunkGenerator#generateNoise(WorldInfo, Random, int, int, ChunkData)
method and just go through the ChunkData by using some nested for loops.

[lost matrix]

What are you trying to do?

[heady spruce]

just testing some things. i want to broadcast just a message. if its not possible thats ok too

[limber marten]

Oh ok, I thought ChunkData could only be accessed during the gen state of a world. Thanks, i'll try this out ^^

[lost matrix]

Its possible. But Bungeecord and Spigot are two separate applications. If you want to execute code on Bungeecode then you need to send a message
from spigot to bungee and let it know that it should execute something. This is usually done through the plugin messaging channel.

[golden turret]

which only works if there is online players

at least 1

[heady spruce]

ok i'll try that thanks

[lost matrix]

example:

  @Override
  public void generateNoise(WorldInfo worldInfo, Random random, int chunkX, int chunkZ, ChunkGenerator.ChunkData chunkData) {
    for (int x = 0; x < 16; x++) {
      for (int z = 0; z < 16; z++) {
        double height = noiseGen.at(x, z);
        int mcHeight = (int) (255 * height);
        for (int y = 1; y < mcHeight; y++) {
          Material material = y == mcHeight - 1 ? Material.DIRT : Material.GRASS_BLOCK;
          chunkData.setBlock(x, y, z, material);
        }
      }
    }
  }

mcHeight is between 0 - 255
This just generates dirt with one layer of grass on top

How to force player to hold a specific Item in hand?

and make him not able to scroll over

[lost matrix]

Listen to the PlayerItemHeldEvent and cancel it

And the swap event too. He might press F to swap off and main hand

[golden turret]

and click event too

[lost matrix]

Oh yeah. ItemFrames <- player interact event

And drop too

[golden turret]

he might interact with the item in the inventory

[twilit roost]

uhh

right

[golden turret]

and

if on 1.19

dont forget the allay

[twilit roost]

but how to set it to Main Hand?
even tho if all Hotbar slots are occupied

[golden turret]

the PlayerInvrntory have a getItemHeldSlot method

or something like this

?jd-s

[undone axle]

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

[twilit roost]

when I click it now it gets duplicated

[golden turret]

acutally this would be better

setItem(EquipamentSlot.HAND, item)

[twilit roost]

yep thx

[hushed spindle]

i hate to ask but how long does it typically take for issue reports on jira to get looked at

[golden turret]

you can simply cancel the event if the clicked slot is the current slot

[lost matrix]

anywhere from some days to months

[hushed spindle]

allrighty

[golden turret]

and check if the keyboard slot is the current slot

if (event.getRawSlot() == player.getInventory().getItemHeldSlot() || event.getHotbarButton() ==player.getInventory().getItemHeldSlot()) {
  event.setCancelled(true);
  return;
}```

[shy shadow]

Hey guys, could someone tell me what's wrong here ? It doesn't trigger at all (whether it's the 1st time the player die on the x time)

public class DeathListener implements Listener {
    @EventHandler
    public void onPlayerDeath(PlayerRespawnEvent e) {
        Player player = e.getPlayer();
        int deathCount = player.getStatistic(Statistic.DEATHS);
        if (deathCount == 0) {
            player.getInventory().addItem(new ItemStack(Material.BREAD, 16)
                    , new ItemStack(Material.STONE_SWORD)
                    , new ItemStack(Material.STONE_PICKAXE)
                    , new ItemStack(Material.STONE_AXE)
                    , new ItemStack(Material.STONE_SHOVEL)
            );
            player.sendMessage(ChatColor.GREEN + "Tu as reçu le kit de la honte, tu ne l'aura qu'une seule fois !");
        }
    }
}```

[tender shard]

you can always duplicate items in creative mode

[twilit roost]

ye I didn't realize that :DD

[tender shard]

what doesn't trigger?

the whole event? or the deathCount == 0 part?

[shy shadow]

The whole event

[tender shard]

did you register it?

[golden turret]

^

[shy shadow]

Yep, it worked when I was listening to the playerDeathEvent, but it was giving items before the player respawns

[twilit roost]

I was spamming key the treasure was at and it went thru

[shy shadow]

So I switched to the PlayerRespawnEvent, and it doesn't work anymore

[golden turret]

there is another event i guess

[tender shard]

if you just print a message at the first line in that code, does it get printed?

[golden turret]

?jd-s

@lost matrixty for the post it's starting to make some sense

[shy shadow]

Yup

[golden turret]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/inventory/InventoryDragEvent.html

[severe turret]

but when i join and leave the json is always null

[golden turret]

@shy shadow

[shy shadow]

I put a sout in the 1st line and it does appear in the console yes

[golden turret]

wrong ping

[shy shadow]

No worries 😄

[golden turret]

@twilit roost

[twilit roost]

thx

[golden turret]

it is a subclass from InventoryClickEvent

i guess you can use the same code then

[lost matrix]

Which json?

[severe turret]

with the playerdata

[twilit roost]

smhw I need to get slot int
Maybe getting itemstack and then checking on which slot has the item?

[shy shadow]

public class DeathListener implements Listener {
    @EventHandler
    public void onPlayerDeath(PlayerRespawnEvent e) {
    System.out.println("test event player respawn event");
        Player player = e.getPlayer();
        int deathCount = player.getStatistic(Statistic.DEATHS);
        player.sendMessage(String.format("You have died %d times", deathCount));
        if (deathCount == 0) {
            player.getInventory().addItem(new ItemStack(Material.BREAD, 16)
                    , new ItemStack(Material.STONE_SWORD)
                    , new ItemStack(Material.STONE_PICKAXE)
                    , new ItemStack(Material.STONE_AXE)
                    , new ItemStack(Material.STONE_SHOVEL)
            );
            player.sendMessage(ChatColor.GREEN + "Tu as reçu le kit de la honte, tu ne l'aura qu'une seule fois !");
        }
    }
}```

With this, the sout does print in the console, and the player receive the message You have died x times 🤔

Edit : Found the solution, had to put 1 instead of 0, since the previous event was trigger before the "event", but this is now triggered after, so it's not 0 but 1 ! Thanks for your help !

[severe turret]

it creates the file with the uuid

like 48ff3303-e9e0-301e-a7b1-e3d2d39b171d

[golden turret]

just try copy the same code from the InventoryClickEvent

[severe turret]

and this is the content

{}

it should put the uuid and name on the map

[lost matrix]

Well... then you didnt write anything into the PlayerData while the player was online...

[twilit roost]

InventoryDragEvent doesnt have getSlot or any other method for getting slots

[golden turret]

yes it does

it extends InventoryClickEvent

so it have

[twilit roost]

not in my case therefore

all I can get is rawSlots

[golden turret]

oh yea

sk

getInventorySlots

and check if it cointains the held item

so something like this @lost matrix

[stark carbon]

why noClassDefFoundError in gradle compile ?

at the top of your build.gradle where it says plugins {} add id 'com.github.johnrengelman.shadow' version '7.1.2'

and then shadowJar {

[tardy delta]

kekw

Sure. But you wouldnt create a PlayerDataPersistenceHandler every time a player logs in. You can

This is the full code

[stark carbon]

@lost matrix

[golden turret]

i guess you dont need ()

No need to cast them to floats. Sql can handle doubles.

[golden turret]

if something is not specified

[young shell]

I already know that thats what's in the Javadoc, I've read it, but that doesnt answer my question

Example?

[golden turret]

if you have a block that dont have the waterlogged property

[lost matrix]

For MariaDB you might need to remove the brackets.

UPDATE locations SET locWorld=?, locX=?, locY=?, locZ=?, locName=? WHERE UUID=?

Try that

Hi! Is it possible to broadcast using PluginMessageListener? (to entire Proxy)

[quaint mantle]

eclipse is very annoying

[glass mauve]

click "Add 'requires spigot api' ..."

[tender shard]

spigot doesn't even properly support modules

[quaint mantle]

I tried that

heres what happens

[tender shard]

btw why do you use eclipse if you find it annoying yourself? 😄

[quaint mantle]

Name of automatic module 'spigot.api' is unstable, it is derived from the module's file name.

[quaint mantle]

idk is was recommened

[tender shard]

intelliJ is much easier to use and also way better imho

[quaint mantle]

🤷‍♂️

maybe ill switch later

[tender shard]

but tbh I never saw eclipse complaining about modules. what JDK version are you using?

[tender shard]

just use java 8 and you don't have to worry about modules. 1.8.8 doesnt support anything newer anyway iirc

[wary harness]

well but you need to have diferent font ascent for every boss par positon

[quaint mantle]

java version "1.8.0_331"

Java(TM) SE Runtime Environment (build 1.8.0_331-b09)

Java HotSpot(TM) 64-Bit Server VM (build 25.331-b09, mixed mode)

[tender shard]

wtf

modules were added in java 9

eclipse at its best again I guess

[quaint mantle]

erm

idk

how do i fix it

[tender shard]

no idea. is eclipse also set to use java 8 in the project settings or however its called there?

[quaint mantle]

its the only java version on my computer

soooo

hm I can only speak for intellij, but that one brings its own JDKs too

maybe eclipse also does this? idk

Hey, I've discovered a bug in my custom crafting gui, I can't craft sticks or wooden pickaxe if I use Birch Planks or Spruce, only Oak Planks are accepted
Here is the ingredient map of the wooden pickaxe
{a=ItemStack{OAK_PLANKS x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC, Damage=32767}}, b=ItemStack{OAK_PLANKS x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC, Damage=32767}}, c=ItemStack{OAK_PLANKS x 1, UNSPECIFIC_META:{meta-type=UNSPECIFIC, Damage=32767}}, d=null, e=ItemStack{STICK x 1}, f=null, g=null, h=ItemStack{STICK x 1}, i=null}
We can see when it's a slot where you have to put a Oak Planks there is UNSPECIFIC_META:{meta-type=UNSPECIFIC, Damage=32767}
What I have to add to my code to accept other types of planks or what can I do to verify if the item required has UNSPECIFIC_META:{meta-type=UNSPECIFIC, Damage=32767}?

but i guess you could use that

and you will just check

[limpid bronze]

Yeah but I need to verify if the item required has UNSPECIFIC_META:{meta-type=UNSPECIFIC, Damage=32767} to use them

@severe turret

[severe turret]

you can do

ItemStack[] planks = new ItemStack[number of elements]

[lost matrix]

Are you registering recipes for your custom crafting?

[severe turret]

and then add the custom planks

ig

[lost matrix]

To accept multiple types of wood you simply need to register the recipe for every type of wood.
There is sadly no way to specify custom predicates for crafting at the moment.

[limpid bronze]

I do Bukkit.recipeIterator() for getting the recipes

[lost matrix]

And doing what with them?

Every ItemStack that has no ItemMeta has an unspecific one

[sweet pike]

I'm really confused on how I am supposed to load a config.yml from the resources folder, into the plugins's data folder and have it loaded. bungee api btw

[limpid bronze]

No, I tested it and for exemple Polished Diorite recipe ingredient map is {a=ItemStack{ANDESITE x 1}, b=ItemStack{ANDESITE x 1}, c=ItemStack{ANDESITE x 1}, d=ItemStack{ANDESITE x 1}} and there's no UNSPECIFIC_META

[limpid bronze]

I'm verifying if the items in the craftings slots are the right one

[lost matrix]

How?

[lost matrix]

https://www.spigotmc.org/wiki/using-the-bungee-configuration-system/

[sweet pike]

That only created a blank config.yml, not one loaded from my resources folder

[severe turret]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/persistence/PersistentDataType.html

you can use this to create a new Tag<Material>

[glossy venture]

i assume you mean Polished Andesite
or is your recipe system broken

[lost matrix]

Then you missed this part:

        FileOutputStream outputStream = new FileOutputStream(configFile); // Throws IOException
        InputStream in = getResourceAsStream("config.yml"); // This file must exist in the jar resources folder
        in.transferTo(outputStream); // Throws IOException

[limpid bronze]

oh yeah polished andesite

[lost matrix]

No

[lost matrix]

And no

[glossy venture]

use nbt yeeee

[sweet pike]

I do not have an InputStream#transferTo method

any alternatives?

[lost matrix]

Is there a way to change the bungeecord chat type back to chat?

[lost matrix]

2 outcomes

1. An exception is being thrown
2. Your file is being copied

[sweet pike]

i mean like, my bungee plugin is running language level 8, so that method doesnt exist, so what should i do.

ah nvm, maybe i can do something with the bytes

[glossy venture]

read with buffer and then write that

[lost matrix]

Have you tried both methods? The post specifies two approaches. One for older versions.

[glossy venture]

byte[] buf = new byte[1024];
while (input.read(buf) != 0) {
    output.write(buf);
}

idk if thats how that works but whatverr

might have to change the condition to smth else

[lost matrix]

eh. buffering. I'd just read all bytes and then write them in one batch

[glossy venture]

that might use a lot of memory depending on file size

[limpid bronze]

Depends on the type of Recipe, if it's a ShapedRecipe I create a list of possible of positions and verify for every position if all the items is positioned good, if it's not we go into another position and do the same thing, if no position matched we can't do a craft, if a position matched we set the result slot
To verify if the item is good, I do: (specifiedItemStack and neededItemStack are null/air || specifiedItemStack and neededItemStack are similar) && specifiedItemStack's amount is higher or equal to neededItemStack's amount

[glossy venture]

and this works too
i think this is how the transferTo method is implemented internally

[lost matrix]

(sarcastic voice) Yeah. Because someone has a 2MB config file with 20k lines of code.

[glossy venture]

yes

nah but for other files you may need to copy buffering is the way to go

might want to copy an icon or image or smth

or extract a native

[lost matrix]

So you are not using the RecipeChoices?

[glossy venture]

i did something similar

for a default crafting inventory

the code is on github

could take a look at it

[limpid bronze]

No, do I have to use that?

[lost matrix]

A multi material choice could look like this
[STONE, COBBLESTONE, ANDESITE]
When you just get it as an ItemStack then it will be only
STONE
Checking on equality by simply calling isSimilar() on this ItemStack ignores the other two.

[lost matrix]

Create an Inventory.
In a manager you define a Map<UUID, YourInventory>
When someone opens the ender chest you check if they have a mapped inventory and open it instead.
You can map 2 UUIDs to the same Inventory instance.

[limpid bronze]

Yeah but ShapedRecipe's ingredient map don't have array or list of itemstack that can be used for a slot

[lost matrix]

They have RecipeChoices

Which are of type Predicate<ItemStack>

Huh?

ok...

[glossy venture]

use a multimap for infinite ender chests

per player

[lost matrix]

ew

[minor fox]

Does anyone have experience synchronizing inventories across multiple server instances?

[limpid bronze]

Yeah I see that, I've printed getChoiceMap() and print list and that's good
But it's list of ItemStack or Material?

[lost matrix]

Concurrent sync or data transfer sync?

[lost matrix]

No

[limpid bronze]

No what

[minor fox]

Data transfer

concurrent could potentially work too

[lost matrix]

You would need to serialize the inventory and store it in a place that is accessible for every instance.
For example a DB.

[minor fox]

Are there any built in solutions when it comes to serializing it?

[lost matrix]

There is just one big issue with transferring between instances because the writing into a DB is slower than the actual transfer

[lost matrix]

Kind of. You can use the BukkitObjectOutputStream to serialize an ItemStack[] to raw bytes or a Base64 String

[limpid bronze]

So it's a list of Material?

[lost matrix]

Its not a list of ItemStacks or Materials.
getChoiceMap() returns a Map<Character, RecipeChoice>

[quaint mantle]

I'm trying to add a new item into the game called TNT Wand, with an enchantment glint. I added the code with no errors, following a tutorial, and the is listed in /help , but when I type /givewand , it shows up in chat, and isn't showing the suggested usage

[minor fox]

Yeah I'm worried the player changes server before the DB is updated... I've thought about doing a server switch cooldown whenever their inventory is updated, but not sure if that's the only approach

[quaint mantle]

commands:
  givewand:
    description: Gives a wand to the player
    usage: /<command>
``` like is this the problem?

[lost matrix]

I made a model for this. One moment.

[quaint mantle]

ok I checked the logs, and my server is registering the command

the problem is that its not spawning in the item

[lost matrix]

So you will def need to bring the proxy into this

Those are the two approaches

[river oracle]

big probelm with your question.
A. We don't know the tutorial
B. You shared 0 code and shared a config
C. You added 0 context other than it doesn't work

[brave goblet]

why does HumanEntity exist? when u could just have player

[river oracle]

HumanEntity can be emulated by NPC's

an advanced NPC could utilize all methods provided by HumanEntity to open inventories and more

[brave goblet]

Ah fun

so could i cast human entity to player?

[river oracle]

The question is the likely hood of such an event occuring if your thinking about casting its generally safe to automatically cast blindly, but I generally wouldn't advise it

your kind of just playing the odds with that one

[lost matrix]

Basically what you need to do is save the players data, wait for the DBs write to be done, and only then you should transfer the player over.

[brave goblet]

sounds cool :/

I'm 14 min into the video

hope thats enough information! 🙂

[limber marten]

What is the new equivalent to read nbt data from a file? NBTInputStream doesn't exist anymore. I'm trying to read a schematic file.

    FileInputStream stream = new FileInputStream(file);
    NBTInputStream nbtStream = new NBTInputStream(new GZIPInputStream(stream));
    CompoundTag nbtdata = (CompoundTag) nbtStream.readTag();

[limpid bronze]

Okay so I replaced in the previous verification the specifiedItemStack and neededItemStack are similar to getChoiceMap().get(cha) != null && getChoiceMap().get(cha).test(specifiedItemStack)
I tested with wooden pickaxe and it's working, when i'm trying to do sticks it's not working I'm searching why

[lost matrix]

This looks better

How can i get players in a certine radius of a location

[quaint mantle]

anyone have good guide on 1.8.8 custom items?

[river oracle]

yea I got you gimme a second

[lost matrix]

Update to a non-ancient version that is actually played and use the PersistentDataContainer

[river oracle]

he just wants enchant glow lol, but that item builder though lmao

thats the weirdest singleton I've seen in my life

[lost matrix]

World#getNearbyEntitites(...)

[naive bolt]

How do i get a BoundingBox

[lost matrix]

You dont need one if you just want to get them in a radius

[naive bolt]

do i just give it a block radius

[lost matrix]

Collection<Entity> players = world.getNearbyEntities(location, radius, radius, radius, entity -> entity instanceof Player);

  public Collection<Entity> getPlayersAround(Location location, double radius) {
    World world = location.getWorld();
    return world.getNearbyEntities(location, radius, radius, radius, entity -> entity instanceof Player);
  }

[heady spruce]

Does anybody know how to play Sounds using PluginMessaging with Bungeecord?

[lost matrix]

You need two plugins. One that runs on the Minecraft servers and one that runs on the Proxy server.
Then you send a message from the minecraft server to the proxy server and the proxy server notifies
every minecraft server, which will then play sounds for their players.

[quaint mantle]

I just want to even make an item xd

cant even do that

[naive bolt]

how can i make an entity a player

[naive bolt]

says i cant give it an entity

[lost matrix]

casting

[quaint mantle]

like its registering the commands

[naive bolt]

needs to be player

[quaint mantle]

(Entity) player

[naive bolt]

Where

[lost matrix]

please add brackets to your loop

and addPlayer((Player) player)

[naive bolt]

ty ty

can i edit a bossbar too

[lost matrix]

You mean the text and progress?

[naive bolt]

yea

[lost matrix]

Sure... just set the text and progress

[naive bolt]

how do i know the bossbar key

im wanting to change it in a diffrent event

so on death it is removed

[lost matrix]

Keep track of the BossBar

[naive bolt]

so i can use the entity id and store the bossbar with it

smart

[lost matrix]

Google what "uuid" is an acronym for

[naive bolt]

i figured

[pastel relic]

Hey, so I get this error https://srcb.in/FwO1qBonSM and i can't seem to fix it, I tried checking if target returns null or not, I tried checking if the users is offline / online but nothing worked, I am still getting the same error. Can anyone help?

[tardy delta]

show code

my first guess it that youre doing if (Bukkit.getPlayer("name").isOnline())

[brave goblet]

public void InvClickEvent(InventoryClickEvent event){
    System.out.println("Fired");
}```
This doesn't fire if i swap hotbars but if I add 
```java
if (event.getAction() == InventoryAction.HOTBAR_SWAP || event.getAction() == InventoryAction.HOTBAR_MOVE_AND_READD || event.getAction() == InventoryAction.MOVE_TO_OTHER_INVENTORY) {
    System.out.println("Fired");
}```
This does fire why is this happening?

[pastel relic]

something like that

wait

This is just the code I'm using

[tardy delta]

Bukkit.getPlayerExact is returning null

and i guess you utils method doesnt lik that

also args[0] can never be null

[pastel relic]

I tried Bukkit.getPlayer and it did the same thing

[tardy delta]

null too lol

[pastel relic]

oh

[tardy delta]

you should check if the target is null instead of args0

[pastel relic]

I did

it didnt work

[crimson terrace]

is there any way to change the path created by ConfigurationSerialization to a different name without moving packages?

[tardy delta]

Player target = Bukkit.getPlayerExact(args[0]);
if (target == null) {
  sender.sendMessage("target isnt online");
} else {
  Location safespot = Utils.findSafeLocationFor(target);

  // other stuff
}```

wheres the code

player is null lol

doesnt make sense if you did what i told

your utils method accesses a possibly null object

not the if else

how do i get the health of an entity on entitydamage event

[mortal hare]

this.changedSlots = Int2ObjectMaps.unmodifiable(modifiedStacks);

one FUCKING LINE

[earnest forum]

cast it to living entity

[mortal hare]

just for this immutability

i need to do reflections for this bullshit

[river oracle]

what u doing

[pastel relic]

oh, that worked

[mortal hare]

packet manipulation

[pastel relic]

ty @tardy delta & @earnest forum

[mortal hare]

im building ui lib

[river oracle]

what type of packet manip you doing

[rough drift]

can you remove the text before a log, like [time] [main/INFO] Something

[earnest forum]

yes

use the system.out.println

[rough drift]

I need it to print some text based ui on start

[earnest forum]

instead of logger

[rough drift]

it auto adds it

it adds even more text

[river oracle]

remove the servers logger

just get rid of it

[rough drift]

yeet

[river oracle]

simple enough

[rough drift]

well no tbf I just need to bypass that in certain scenarios

[river oracle]

little bit of reflection and boom its gone

[rough drift]

well I need it to be there

just not always

actually I am fine with the logger, I just don't want the text behind it

[river oracle]

well i'd just remove it 100% of the time for maximum effectiveness

the date and time?

[rough drift]

date, time, server thread and plugin which printed from

[mortal hare]

why would you want to do that

[rough drift]

I need to make a clean text based UI

and that thing is not great for it

[mortal hare]

but these are logging data

[river oracle]

then read the latest.log and reformat it

[mortal hare]

nots some public chat

its useful for debugging

[rough drift]

well I need to print it to console

not latest.log

[river oracle]

again reformat the latest.log and reformat it

[rough drift]

what?

[river oracle]

its so easy to reformat it and trail real time as well

sending commands is also easy if you use something like tmux or screen

[rough drift]

wdym reformat

[river oracle]

if you trail the latest.log you can remove and add whatever the fuck you want to the lines put in the log file

no messing with the server required

[rough drift]

How would that help me print to the cmd/terminal the server is running in...?

[old sail]

Why doesn't Skeleton entity have GENERIC_ATTACK_SPEED attribute?

[rough drift]

because it uses a bow

and the bow has a fixed attack speed

[old sail]

So there isn't any way to speed it up?

[rough drift]

not really

there might be some events

[river oracle]

https://github.com/Y2Kwastaken/mcpython-panel/blob/master/native_components/server_manager.py

its in python but its my server panel that I scrapped together

[old sail]

How can I change skeleton attack speed using any event? 🤔

[rough drift]

I am talking from a plugin's perspective, no extra software

[pastel relic]

can you make args show up when you type a command without using subcmds?

[rough drift]

can I just print A to the console without the extra stuff

[river oracle]

oh then you have to remove the server logger

[rough drift]

I don't want to remove the entire logger, it should still be used

[river oracle]

I wouldn't see another way to do it

[rough drift]

I just don't want the extra stuff

maybe using terminal thingy

like move back to start of line and \b the shit out of it

[river oracle]

seems like a hastle for literally little to no gain if I wanted a nice format I'd use my own panel as I do

[twilit roost]

any advice on doing so?

[rough drift]

there might be a bow charge event

[mortal hare]

i wonder how protocollib solves issues with paper's packet limiter

[pastel relic]

?

[mortal hare]

since it listens for packets before it reaches paper's packet limiter

[naive bolt]

say i have the health of an entity at 70.75172519683838 and i want to set a bossbar to the health how can i make the number between 0 and 1.0

using the starting health of the mob

[rough drift]

num / 100

would move it to .7

[tardy delta]

i guess you are talking about tabcompletion

[pastel relic]

yes.

I didn't know what it was called ^^

[tardy delta]

override TabCompletor#onTabComplete to return a list which the options

depending on the args length

[pastel relic]

and how do I do that?

[tardy delta]

look at some post

forum post

[pastel relic]

okay, thx again

            }
        }``` Will this `break` break from both for loops or just the nested one?

[mortal hare]

it would break from nested one

[subtle folio]

got it

[naive bolt]

Thats very specific to that health tho

[tardy delta]

this is how im doing it
https://github.com/FourteenBrush/MagmaBuildNetworkReloaded/blob/aa1c94b533647e2e50ebfa36da62107ca6b60e13/src/main/java/me/fourteendoggo/MagmaBuildNetworkReloaded/commands/VanishCommand.java#L88

[earnest forum]

floor it and then divide by 100

[tardy delta]

time to go to my graduation smh

[naive bolt]

what if i have the health of like 489

[subtle folio]

bro

what is this code

so much repeating code

[tardy delta]

shut

[rough drift]

worse than smpcore

[tardy delta]

im using command framework now

[subtle folio]

did you make the framework

[vernal abyss]

I am doing in a SignChangeEvent ```java
Block block = event.getBlock();
Sign sign = (Sign) block;

```[18:39:47 ERROR]: Could not pass event SignChangeEvent to PixliesCore v2.0.0
java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_19_R1.block.CraftBlock cannot be cast to class org.bukkit.block.Sign (org.bukkit.craftbukkit.v1_19_R1.block.CraftBlock and org.bukkit.block.Sign are in unnamed module of loader java.net.URLClassLoader @759ebb3d)```
event.getBlock() should give me an org.bukkit.block.Block, not an org.bukkit.craftbukkit.v1_19_R1.block.CraftBlock so I don't know what's going on.

[subtle folio]

or r u bad

[tardy delta]

hehehe die

undocumented code hehehe

[subtle folio]

bro

i shouldve never came here

[rough drift]

more documented than mine

[mortal hare]

i see nothing wrong with this approach of command managing, its just that its hardcoded more

[tardy delta]

lmao its from my old plugin

[mortal hare]

but the performance is way better

than iterating nodes of command args

[rough drift]

I just make my command framework use hashmaps

won't be as fast as raw if's

but it's fast enough

[subtle folio]

enough

[naive bolt]

That still wont work

if i have a big health of like 400

i will get 4 and it has to be between 0 and 1

tho i gotta write it in disc not yet pushed

[subtle folio]

no cap

[rough drift]

which one do you want, the class based one or the non class based one

[earnest forum]

im not sure if this will work

but divide 1 by the max health

and then multiply by the current health

[subtle folio]

class based

[rough drift]

k

[subtle folio]

non class based is kinda cringe imo

[naive bolt]

i hate math

[subtle folio]

just gets super messy

[rough drift]

Eh i have it because I can

[subtle folio]

yk

[rough drift]

for small things it's useful

[subtle folio]

well yeah i can see that

but if you've heard of crazy crates

i think they have like a 2k line comand listener

a bunch of commands

[rough drift]

o no

[subtle folio]

just in if else's

[rough drift]

https://github.com/IkeVoodoo/LSSMP/tree/v3/src/main/java/me/ikevoodoo/lssmp/commands

[subtle folio]

not even switch 😢

[mortal hare]

(health/maxhealth) * 100 would always return you health from 0 to 100

[rough drift]

that's an example implementation

not everything is 100% finished

[mortal hare]

just make sure that the max health wont have 0 in it

[rough drift]

command system is still a WIP

[mortal hare]

otherwise your computer will blow up

[naive bolt]

so the max health is 500 of a warden

[earnest forum]

dont need the *100 part but yeah

[mortal hare]

if you want health from 0 to 1 then yeah

[subtle folio]

good commit

[rough drift]

yes

I sometimes just make mega commits

they are 20+ files changed in one commit

[subtle folio]

why is there a new package for each class?!?!

[rough drift]

it's a new package for each command tree

[subtle folio]

ah I se

[rough drift]

it's neatly organized

[subtle folio]

thats cool

very neat

[mortal hare]

(450 current health warden/500 max health warden) * 100 would you return 90 health for you

[earnest forum]

hes using bossbar so *100 isnt needed

[heady spruce]

sheesh

[mortal hare]

oh

ok

[subtle folio]

what is SMPCore?

[mortal hare]

then yea dont add * 100

[rough drift]

The entire backbone
