development

[lyric gyro]

yeah well

[merry knoll]

just checked the repo

[lyric gyro]

that's the significance of major versions

[merry knoll]

those are the latest there

https://maven.enginehub.org/artifactory/repo/com/sk89q/worldguard/worldguard-bukkit/

https://maven.enginehub.org/artifactory/repo/com/sk89q/worldedit/worldedit-bukkit/

[lyric gyro]

https://maven.enginehub.org/repo/com/sk89q/worldedit/worldedit-bukkit/7.2.12/

[merry knoll]

ah its the formatting

ye mb

[lyric gyro]

i mean tbf this is a rule of thumb in general for all kind of development (especially cuz "public" stuff can change between individual snapshots)

but bukkit did ya bad

[merry knoll]

what are you using for dependency handling?

maven? gradle?

[sonic quartz]

maven

[merry knoll]

then put it there

<dependency>
<groupId>com.sk89q.worldedit</groupId>
<artifactId>worldedit-bukkit</artifactId>
<version>7.2.9</version>
<scope>provided</scope>
</dependency>

[sonic quartz]

<dependency>
<groupId>com.sk89q.worldedit:worldedit-bukkit</groupId>
<artifactId>worldedit-core</artifactId>
<version>7.2.9-SNAPSHOT</version>
<scope>provided</scope>
</dependency>

[merry knoll]

you gotta add repo too obv

[merry knoll]

there is nothing such as worldedit-bukkit:worldedit-core

if you want core then you need to do

<dependency>
<groupId>com.sk89q.worldedit</groupId>
<artifactId>worldedit-core</artifactId>
<version>7.2.12</version>
<scope>provided</scope>
</dependency>

https://maven.enginehub.org/artifactory/repo/com/sk89q/worldedit/worldedit-core/

you can explore the repo yourself

https://maven.enginehub.org/artifactory/repo/com/sk89q/worldedit/

here exactly

but if you are developing for bukkit

then use the bukkit implementation, not core

[sonic quartz]

It works now, thanks

[sonic quartz]

What may be the reason I don't get the item in the shulker after this code?https://paste.helpch.at/egasigodus.java

[sonic quartz]

I should've used getShapshotInventory

[dusky harness]

Haven't looked in the code as I'm on phone rn but snapshot can't be modified

[proud pebble]

getState return a copy, that wont update the original shulker

[sonic quartz]

Anyway I changed getInventory to getSnapshotInventory in the code and it worked

[proud pebble]

fair

[queen plank]

I have a class with the generic <T extends Number> and want to test a predicate Predicate<T> with the absolute of T val. How do I do this the best way? Is it even possible or do I have to change Predicate<T> to Predicate<Double> or something?

[lyric gyro]

huh

class Foo<T extends Number> {
  T number;
  Predicate<T> pred;
}

[merry knoll]

you probably need to write your own math method to suit Number

i am not sure if abs works with Number

[queen plank]

public class Foo<T extends Number> {
  public boolean test(Predicate<T> pred, T val) {
    return pred.test(Math.abs(val));
  }
}

[queen plank]

It does not :/

Guess I'll have to do my own wrapper or smth then

[merry knoll]

then you need your own method for taking abs of number

with all the subclasses

so.. int double float etc

[queen plank]

Ik :V

Thx tho

:>

[lyric gyro]

I mean given that Number is a freely extendible abstract class, you can't possibly consider all implementations

[merry knoll]

in his implementation, he probably can though

[lyric gyro]

how come?

[merry knoll]

as in, unless the method is open he knows what types are going in there

[lyric gyro]

I suppose, though a "proper" solution would be to do the abs inside the pred itself given that it is type aware

[merry knoll]

kinda the same issue though i feel like

[lyric gyro]

how come?

[merry knoll]

its type aware but its still freely extendable

guess you could just throw an exception

[lyric gyro]

not sure what you mean

new Foo(BigDecimal.TEN, bd -> bd.abs().compareTo(BD.ZERO) > 0)
new Foo(-7L, l -> Math.abs(l) > 100L)
etc

[merry knoll]

ah, thats what you meant

yeah thats cleaner

actually might yoink for my vector classes

[lyric gyro]

lmao

[merry knoll]

for block vectors

i normally just extend this to make a separate block vector

[lyric gyro]

could also take a UnaryOperator<T> abs so new Foo(num, Math::abs/BigDecimal::abs/etc, predicate)

that's probably the best approach

[icy shadow]

yeah

[merry knoll]

still gotta check how the :: thing works

👀

im guessing its similar to C++ one?

okay, apparently its quite different just a shorthand for lambda one liners?

[icy shadow]

it's a method reference yeah

[merry knoll]

hm, kinda useful i guess

a bit more concise than going{ x.foo(bar) }

[lyric gyro]

point-free code 😌

[icy shadow]

relieved

now give us composition as an operator

[lyric gyro]

. pleasing face

[icy shadow]

or at least a::b.then(c::d)

[lyric gyro]

pleasing

[icy shadow]

pleasing

[lyric gyro]

pleasing

[icy shadow]

fuck that

i hate casting i hate casting

[lyric gyro]

pensive

[merry knoll]

has it too nice

[icy shadow]

looks shit

[merry knoll]

actually allows me to lift the {} out of the method

way better than this

how can i replace a specific word or line in a lore? i've tried iteratiing through it but to no avail

[dense drift]

Get the lore, put it in a variable, replace the string, set the lore and meta back to the item

[sonic quartz]

If I use getPlayer with UUID parameter, will it get me the player if he's offline?

[broken elbow]

getPlayer's return type is a Player. Which can only represent an online player.

if you use getOfflinePlayer then yes.

[dense drift]

Yeah

[proud pebble]

the docs do say that if the player is offlune then getPlayer returns null

[floral beacon]

Hello
for PlayerInteractEntityEvent bukkit/spigot event, how can i detect if player's hand is empty / no items in his hand?
i know how to check if he is holding with hand he's interacting with a specific item, but not no item

 if (player.getInventory().getItemInMainHand().equals(Material.DIAMOND_SWORD))

so how to check if his hand is empty

[stuck hearth]

d; spigot Player#getInventory

[uneven lantern]

org.bukkit.entity.HumanEntity#getInventory

@NotNull
PlayerInventory getInventory()```

Description:

Get the player's inventory.

Returns:

The inventory of the player, this also contains the armor slots.

Requested by: Doctor Zod • spigot

[stuck hearth]

If I had to guess it would probably be Material.AIR since it shouldn't return null

Alternatively, just log what the empty item is

[floral beacon]

tested, doesn't work

[floral beacon]

how do you mean this

ok i logged as

Bukkit.getConsoleSender().sendMessage(" " + player.getInventory().getItemInMainHand())

it outputs (when i interact with hand)
ItemStack{AIR x 0}

[proud pebble]

your checking if ItemStack is equal to Material.

so try player.getInventory().getItemInMainHand().getType().equals(Material.AIR)

getType() returns the material that the itemstack is.

if its air, then its empty

[floral beacon]

this worked

thank you very much

[proud pebble]

when comparing something in the future, make sure that the 2 things you are comparing are of the same type otherwise it will always return false.

i bet someone will now tell me thats not always the case for whatever reason and ill become the stupid one lol

[lyric gyro]

well

it isn't strictly true

but it's "true enough"

[proud pebble]

i bloody knew it

[high sigil]

    @Override
    public String onRequest(Player player, String params) {
        if(params.equalsIgnoreCase("towny_kasaba")){
            if(PlaceholderAPI.setPlaceholders(player, "%advancement_has_town%")) == "true") {
                return "sa";
            }
        }

how i can do this?

[proud pebble]

how can you do what exactly?

[high sigil]

i trying get %townyadvanced_has_town% output

but idk how can i get it

[merry knoll]

you cant compare strings directly

like that

[high sigil]

how i can do that?

theres a example or

[merry knoll]

.equals kullan onun yerine

[proud pebble]

wouldnt it make more sense to hook into towny and use the towny api rather then using papi?

[merry knoll]

dm for turkish lets not spam here with another language

[merry knoll]

yeah proper solution

[worn jasper]

any ideas if it's still possible to send a message above the actionbar?

Aka you have the actionbar, then that message and only then title and subtitle.

I think it's where item names are displayed.

[dense drift]

no

[worn jasper]

Oh okay, I can't remember when that was possible, think 1.8

thanks anyways

[dense drift]

I dont think it was ever possible?

[worn jasper]

it was.

[hoary scarab]

You can probs send a switch item packet.

[worn jasper]

let me see if I can get a screenshot

[dense drift]

it was probably done by replacing the item in hand for a tick

[worn jasper]

yes but wouldn't then when switching back to the other item, override the name?

[dense drift]

[worn jasper]

aka it would also only display the name for only a tick

[hoary scarab]

Maybe you can find the held item packet and set the name If the switch item packet isn't what you're looking for.

[worn jasper]

tbh never worked much with packets but will check it whenever it's a priority xD

thanks

[hoary scarab]

Yeah with the spigot api it's missing things like that and then they complain when you don't use the api lol

[sonic quartz]

how can I destroy pasted scheme with worldedit? I want to remove all the pasted blocks but leave other blocks within scheme area which were placed manually. It's like pasting a scheme without replacing existing blocks with air, but replacing blocks that belong to the scheme with air

[trail burrow]

been looking for a place to read up on how to upgrade my plugin to minimessage, anyone know of such a doc?

[merry knoll]

[trail burrow]

thanks

[merry knoll]

is the player location in playerRespawnEvent

the death location?

[proud pebble]

i would say no?

[merry knoll]

there is a seperate spawnlocation defined

so i am not sure honestly

[proud pebble]

hmm

id say try it and find out

[merry knoll]

lemme be lazy

What error

[trail burrow]

did you look at the link?

[winged pebble]

ngl, assumed it was the code in pastebin form

[trail burrow]

I will label next time to be less confusing

[winged pebble]

How are you providing Adventure at runtime?

[trail burrow]

? I don't always understand the language, the above code is in my main class

[winged pebble]

The issue you're having is that the code doesn't know how to find adventure at runtime

[trail burrow]

I thought I followed the video's instructions

[winged pebble]

It seems like you've shown the IDE how to see what library you are using, but the library isn't available at runtime

Which video?

[trail burrow]

https://www.youtube.com/watch?v=NYb08bC_fOo

[winged pebble]

Are you using maven?

Also, are you using spigot or paper?

I'm going to assume you're just using spigot

[trail burrow]

server is paper, or did you mean in code

[winged pebble]

the server

[trail burrow]

paper-1.19.2-142

[winged pebble]

let me see your pom.xml

[trail burrow]

https://paste.helpch.at/yoqobuluge.xml

[dense drift]

You dont need buķkit platform if you will always use paper

Paper has native support for adventure, e.g. you can just do Player#sendMessage(Component)

[trail burrow]

OK, what if the plugin is run on Spigot servers?

[icy shadow]

then it wont work

without shading

and the bukkit platform

[trail burrow]

if I make it work on Spigot then it will work on Paper also?

[icy shadow]

yes

[dense drift]

        <dependency>

        </dependency>```
make this `compile` and shaded it to a package

and you also need adventure-api I think

[lyric gyro]

it's transitive

[dense drift]

great

[worn jasper]

if I use #sendRichMessage() I don't need to deserialize it anymore right?

[worn jasper]

ok so yes, thx

[shell moon]

If a player with a custom health amount (using setMaxHealth or modifying attribute) dies

it resets back to normal? (after death)

[dense drift]

No

I believe it will start from 20hp (or max if it is lower than 20) though

[shell moon]

ahhh so to remove custom health i need to set max to 20 then

[sonic quartz]

is there a better way to replace specific blocks in the area with air? Mine makes the server lag https://paste.helpch.at/rekohexuqi.java

[sterile hinge]

Don’t do all that Bukkit.getWorld stuff all the time

[merry knoll]

can also use nms replacing

[proud pebble]

bukkit setblock should beable to do like 60k blocks a second and that doesnt look like more but tbh it depends how often the blocks are changed

nms is definitly the way to go if your gunna be doing somelike like prison mines for example

[merry knoll]

tbf i didnt check the code posted, on phone atm

isnt there a normal bukkit method to setting blocks without light updates?

[sonic quartz]

you mean what I used?

[merry knoll]

or physics

[sonic quartz]

what is nms?

[merry knoll]

then defo dont do it through nms

you access internal mc server

and set block directly

instead of doing through the api

[proud pebble]

depending on the method it can update up to like 14million blocks a second

[merry knoll]

it avoids all light - physics updates

but you need to care to not set blocks on unloaded chunks etc

so not for the inexperienced

[proud pebble]

i always got stuck cus of the 2048 long bitsets

i just gave it null

[merry knoll]

does getWorld just take from a hashmap?

[sonic quartz]

after my question I thought that maybe I can just send a few commands from WorldEdit in the console for each type of block like set 2 edges of the area and then /replace

[merry knoll]

then use world edit api

why are you using commands

https://worldedit.enginehub.org/en/latest/api/

[sterile hinge]

It’s work that can be avoided while also making the code more readable

[merry knoll]

yeah, i am just asking if they are hashed

[sterile hinge]

I think so

[merry knoll]

my guess would be that its hashed against world uuid

[lyric gyro]

it's funny because world uuid is just a bukkit construct, not a vanilla thing

[sonic quartz]

I just don't know how to convert //pos 1, //pos 2 and //replace into code and how to find this information on the site

[merry knoll]

^ try reading

[merry knoll]

i am willing to bet that getWorld(name) is used way more than the uuid version

uuid use case is quite rare i feel like

and its hashed against the name

apparently

[lyric gyro]

oh 100% yeah

but like there is no world uuid in vanilla, idk why it's a thing in bukkit

[hoary scarab]

Well you can't have 2 worlds with the same name. (Pretty sure) so there is no point in a uuid

[merry knoll]

uuid in general is a bit better imho as an actual id

size is known etc

but on use cases, where user needs to put something in as name it becomes kinda impractical

at least they are still hashing against the name

[lyric gyro]

it's just a dumb introduction

[dense drift]

Bukkit moment

[queen plank]

How does this make any sense? I get Type mismatch: cannot convert from element type Object to Player from the method. The class Driver has the generic <E extends Event>. I've suppressed the rawtypes warning on Driver d

[stuck hearth]

Smells like Type Erasure, but more importantly you probably shouldn't suppress errors if they're fixable, which I imagine in your situation is very doable.

[queen plank]

I can´t set d to the type Driver<?> as then I can't call getUsers(<E extends Event>) at all. I don't know what type/class the event is.

So idk how to fix it other than not using generics for d

[stuck hearth]

Why doesn't getUsers just take an Event as a parameter?

[queen plank]

Cuz depending on the event I want to use PlayerEvent#getPlayer (or other event-specific methods) and didn't want to cast in the classes where I know the event type. Ig I can change E to Event for that method though

My big fat brain just remembered I can just cast the Set lol (Set<Player>) d.getUsers(event)

Thx any ways :>

[sterile hinge]

that looks really really bad

[queen plank]

Ik :V

But I want to avoid using Event as a parameter as then I'll have to cast the event a billion times in subclasses...

[sterile hinge]

the issue basically is the getKey call, whatever that is doing

[queen plank]

It's way too much for me to explain, but essentially I have a Map<Driver<?>, "CustomDataClass"> which I iterate over using Map#entySet

[sterile hinge]

build a proper heterogeneous container and you're fine

[queen plank]

Ig

[queen plank]

I guess this is an eclipse bug? The top one works, the bottom one does not lol```java
Set<Player> users = l.getUsers(event);
for (Player p : users)

for (Player p : l.getUsers(event))

[lyric gyro]

depends

a) does it compile? b) what does it say?

if getUsers is generic on T and returns Set<T> then it is not a bug

[sterile hinge]

yeah there are rules about when inferences behaves how

[queen plank]

I know, I was unclear. It was a follow-up from before

[sonic quartz]

Why when I put a block in a hashmap and later get this block and modify it, it doesn't get modified?

How can I modify it properly?

[merry knoll]

block returns clone

store location reference

[sonic quartz]

I've tried hashmap.get(..).getLocation and it didn't work

[queen plank]

Inner i gives me the warning Outer.Inner is a raw type. References to generic type Outer<T>.Inner should be parameterized. How do I get rid of it?

public final class Outer<T> {
  class Inner {
  }
}

public class Foo {
  static Outer<String> o = new Outer<>();

  public static void bar() {
    Inner i = o.new Inner();
  }
}

Generics are difficult :<

[icy shadow]

possibly Outer<String>.Inner

idk i dont think ive used inner classes ever

[queen plank]

Yup, that seemed to fix it. Ig I'll go for that one

Tnx :>

I think he meant store the location instead of block and then get the block on that location and do what you want with the block

^ That would be the more recommended way of doing it

[queen plank]

Is there a way to do something like this? Where you create an interface with more than one method in a constructor?

class Foo {
  Foo f = new Foo(
    class X implements Bar {
      void a() { /*Whatever*/ }
      void b() { /*Whatever*/ }
    });

  Foo(Bar b) {}
}

interface Bar {
  void a();
  void b();
}

Or is it just easier to create two SAM interfaces?

[merry knoll]

if they are always paired, i dont see why you would need a single method one

[queen plank]

Because I don't know how to create a double method interface in a constructor. Or what do you mean?

I could make a bunch of inner classes for Foo that implements Bar but I have a lot of Foo constants so I'd rather not

[merry knoll]

you can just pass this into its constructor:

new Bar() {
  a() {}
  b() {}
}

sorry for shit format, typin from phone

just make an anonymous class implementing your interface

and pass it to constructor

[queen plank]

Ahh, that is how you do it. I didn't know how to create a multi-method interface in a constructor. But that solves it, thank you!

[proud pebble]

you install freedomchat or something like that on your server

or you can send the message as a server message instead of a player message

[dusky harness]

or disable chat reporting

in server.properties

[winter nimbus]

Which setting may that be?

[lyric gyro]

Setting enforce-secure-profile to false will disable chat reporting feature and the client will show a warning on joining the server

It's so painful i have to learn blockchain technologies just to send messages using packets... absurd chat reporting feature

that is so wrong

it doesnt disable it what so ever

Location location = null;

Just use the constructor

d;Location#Location

[uneven lantern]

org.bukkit.Location#Location

public  Location(@Nullable World world, double x, double y, double z)```

Description:

Constructs a new Location with the given coordinates

Parameters:

world - The world in which this location resides
x - The x-coordinate of this new location
y - The y-coordinate of this new location
z - The z-coordinate of this new location

[lyric gyro]

Oh yeah you can do that lool sorry it's been a while, thanks again

[tough nacelle]

Yeah, a lot of people write down the whole everything, pitch, yaw, xyz world etc.. in the newer versions they did this so its saves everything in the correct way and if u do it with this method then there will be no errors at all

[sterile hinge]

Oh god I just saw there are two spaces between public and Location

[tough nacelle]

xd

[stuck canopy]

how can I make my plugin work for every minecraft version?

no you didn't

[dense drift]

oh no, two spaces

[sterile hinge]

Thanks

[worn jasper]

any ideas on what could be causing this? (not my server)

I assume it's related to getting an item but couldn't get much more from it

besides it's also related to a player

for reference, this was that player's inventory

[high edge]

Odd

[worn jasper]

indeed very odd

trying to find an explanation lol

[high edge]

What's the nugget item

[worn jasper]

so I think I might know the issue

aka the issue is excellentcrates

my client has an "afk region" which gives an excellentcrates key every x minutes

I assume the issue is with excellentcrates in this case then?

(cause the location where the player was, was inside the afk region)

[high edge]

Possibly

[worn jasper]

have an idea on a way to test if it's rlly it, thanks for the help either way, will update ya afterwards if ya want

[high edge]

Go to the location he was, and stay there for a bit, if you can turn on debug for the crates if it has any

[worn jasper]

Uhm would a method checking if a player has a permission or is console be able to be static without issues?

[lyric gyro]

yeah

[queen plank]

I have a class roughly like this. What is the best way to avoid the massive else if chunk?

public class Foo<T> {
  public static final Foo<Boolean> BOOLEAN = new Foo<>();
  public static final Foo<Integer> INTEGER = new Foo<>();
  public static final Foo<Double> DOUBLE = new Foo<>();
  /* etc.. */

  public void something(T t) {}

  public static void whatever(Object o) {
    if (o instanceof Boolean)
      BOOLEAN.something((Boolean) o);
    else if (o instanceof Integer)
      INTEGER.something((Integer) o);
    else if (o instanceof Double)
      DOUBLE.something((Double) o);
  }
}

[wintry grove]

what is even your goal here

[dusky harness]

unless you have like 20 of those that's the best way I can think of

[queen plank]

I do lol

Guess I’ll do that, will look great

[queen plank]

Hmm?

[lyric gyro]

Map<Class<?>, Foo<Object>> map

map.get(o.getClass()).something(o)

ye that was what i was thinking at first

but

you could do something else that doesn't have the unchecked cast warning

[queen plank]

Yeah

[dusky harness]

wait idk if you can actually

[coarse gulch]

Hello guys
How can i make a item glowing?
without adding enchantments

[dense galleon]

                    Location loc = new Location(world, clickLoc.getX() + x, clickLoc.getY() + y, clickLoc.getZ() + z);
                    Block block = world.getBlockAt(loc);
                    world.spawnFallingBlock(loc, block.getBlockData());
                    block.setType(Material.AIR);```

Trying to make any block I click on be affected by gravity, though I notice that the fallen block entity that spawns spawns in a slightly wrong location

I'll show you a short video in a sec

Like this

The block seems to spawn with an offset, causing it to not place properly when hitting the ground

[modern warren]

Offset is consistant so you could probably just add x and y to the location so its correct again

[dense galleon]

It works when clicking

Now the issue is that I want that to happen when a player moves

https://paste.helpch.at/lezaviloso.java

That's the code I have, in a PlayerMoveEvent

I'm just doing this to test falling blocks, i know it's very slow on the server

The offset seems to be completely random

[proud pebble]

you cant

i pwrsonally give an item protection 0, dows the same job and doesnt boost an item.

tho can cause a fewissues potentially

[stuck hearth]

Custom enchant moment

[dense drift]

Fr

Good thing about custom enchantments is that they dont even show in lore

[hoary scarab]

Or just add the hide enchantments flag.

[coarse gulch]

Yo guys, any way to edit how enchants look in tools & stuff?

https://imgur.com/kE7Lae6

Something like this

[worn jasper]

that's just editing lore

you hide the enchants and display them in the lore with your formatting

[coarse gulch]

?

[worn jasper]

or whatever ya want

[coarse gulch]

It would become to much complicate

[worn jasper]

?

what's complicated about that?

[coarse gulch]

handle everything regarding enchatments & stuff

you would need to pay attention the the grindstone too

[worn jasper]

not complicated lol

[coarse gulch]

iirc there's no event for the grindstone

i mean

isn't there a easier way with a resource pack?

[dusky harness]

no clue about resource packs but you could also check a player's item every tick

[worn jasper]

that seems harder than without resource pack lmao

[worn jasper]

eh that can be tricky for performance

but yes

[dusky harness]

it should all be "cached" although idk what would happen if you had like 200 players

[coarse gulch]

yeah we'll probably have around 150 players online

[dusky harness]

and also if you do this make sure that you check if the lore is not equal to whatever you want to set it to

[dense drift]

yeah

[tired olive]

you could just do it on inventoryclickevent

[coarse gulch]

what's that? maybe we want to move to another chat i suppose

[dense drift]

you just have to add the symbol before enchantment name

[coarse gulch]

that's exactly what i wanted

[coarse gulch]

easy peasy

[dense drift]

idk if it supports colors, but worth a try

[coarse gulch]

love you mate

[dusky harness]

OR
inventory click event and inv open event

[dusky harness]

ah

[dense drift]

https://www.planetminecraft.com/texture-pack/enchantment-symbols/ looks like you can use section symbol or its unicoded code \u00a7

https://mcasset.cloud/1.19.2/assets/minecraft/lang

you only need to override the enchantment keys @coarse gulch, the pmc link is a texture that does the same thing, you can follow that

[coarse gulch]

yeah i figured it out

thanks!

[dense drift]

np

[coarse gulch]

yessir

thanks

[dense drift]

nice

[coarse gulch]

What about color?

Do you think it's possible to use colors?

[dense drift]

\u00a7 and then the code (a-f 0-9) - \u00a78<star> \u00a77Efficienza

[coarse gulch]

yeah that's perfect

does R works as in minecraft

so it reset the color?

i mean, can i do something like \u00a7r

[worn jasper]

confused is this texture pack or not?

[dense drift]

that is minecraft's coloring system, so yes, it does

[coarse gulch]

you can do it by editing default minecraft files

[coarse gulch]

perfect

Love ya, thanks again

for real

Is it normal that opening it back from the pack it just fucked up all the lines?

o.o

[dense drift]

uh not really

but don't keep all keys

override only the enchantment names, anything else will have the default value

[coarse gulch]

Like this?

[dense drift]

yes

[coarse gulch]

let's see if it breaks again

[worn jasper]

of the server or client?

[coarse gulch]

server resource pack

client files

both

you can do it both way

[dense drift]

yo wtf is swift sneak

[coarse gulch]

?

tffffff

that's probably something they wanted to add and the thrown in the bin

no

wait

that's a thing

[dense drift]

what is a thing?

[coarse gulch]

like

it does exist

[dense drift]

yes, it was added in 1.19

[coarse gulch]

i didn't know it existed

[dense drift]

Added Swift Sneak. It is currently applied to boots, and is not compatible with Frost Walker, Depth Strider, or Soul Speed.
F

ah nvm, it was later moved to leggings

[coarse gulch]

are you supposed to go faster when sneaking with it?

can someone help with maven shading

[dense drift]

wrong channel, dont you think @sonic wedge

what do you need help with @trail burrow

[trail burrow]

trying to shade kyiro adventure-platform-bukkit

[dense drift]

do you have this in your pom? https://maven.apache.org/plugins/maven-shade-plugin/examples/class-relocation.html

and make sure you build the project using package

[trail burrow]

I have that in my pom, build using package?

[dense drift]

yeah, use the package task, not build

if you use intellij, from the maven tab, go to lifecycle and select package

[dusky harness]

they've got ClassNotFoundException which means that it's not being shaded at all for whatever reason

I haven't looked line by line to see if there's some small mistake or typo but in general their pom looked fine

@trail burrow just to make sure - does the jar have the dependencies in the jar? And make sure you're using the shaded jar, not the normal one

[trail burrow]

it only creates one jar, Not sure where lifecycle is

[dusky harness]

gaby why you using maven >:(

[dusky harness]

oh
can you resend pom.xml?

so that someone here can look through it

someone who uses maven instead of me just scanning through it

[dense drift]

old project

[dusky harness]

or maybe ill look deeper into it later

[trail burrow]

https://paste.helpch.at/novopapeni.xml

[dense drift]

<pattern>net.kyiro</pattern> this should be net.kyori

[dusky harness]

💀

I'd recommend just opening up the jar and relocating everything you see

that's what i do

[dense drift]

and don't relocated to shaded.net.kyori, that will cause problems if you/someone else use the same package in other plugins

[trail burrow]

I hate typos

[dense drift]

use something like <group>.<project name>.libs.kyori

[dusky harness]

@trail burrow pinging since you haven't responded with any other details and it's been a while
Can you upload the project, or a separate project meant to just reproduce this issue to github?

[trail burrow]

somehow I broke my project and trying to fix it

[dusky harness]

💀 i guess show the bug or when you get it back to the "original" state try uploading a test project for us to reproduce

also seems like mbaxter in kyori discord is also willing to help - so if they do end up getting the solution plz update here too (so that people don't waste their time looking into an already-solved issue)

[trail burrow]

it will not build correctly, jar is 1/3 the size now

maybe but the code for minimessages is all gone

how do i make mobs hostile at each other (ex: skeletons)? but only if the other mob tests positive for a predicate
i have 2 skeletons, one is on blue team, one is on red. there's also 2 players, one on blue, one on red. currently, the blue skeletons will only shoot red players, and vise-versa (so the skeletons r friendly to their "teammates"). however, i want the skeletons to be able to shoot each other so that they are besties: https://media.srnyx.xyz/java_6wMSp6dvzX.png

also, while writing this, i noticed some of the skeletons despawned, even though they were in my render distance (not in view tho, i just saw their glow) and set to persistent

PlayerMoveEvent.getFrom() returns a Location without pitch and yaw any idea why?

[high edge]

cause it's not relevant information?

[sudden pendant]

it is

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Location.html

[high edge]

For that event it's not really

[sudden pendant]

oh so how would i get it then?

its for a back command i need to set the prev location with pitch and yaw

[dense drift]

what has player move event to do with a back command?

[sudden pendant]

i use getFrom method for getting last position

[high edge]

That's probably not what you should be using

[sudden pendant]

i saw this being used on advanced tp thats why im using it

[warm steppe]

Is it not? Then why is it getting fired when you look around?

[high edge]

You don't

[leaden sinew]

I’m assuming you mean a /back for teleporting? If so, use the teleport event.

[dark garnet]

so i would have to create my own targetting ai basically?

[leaden sinew]

No, you can listen to the entity target event and set a new target

[dark garnet]

wouldnt that only trigger if it sees another target tho, like a player?

cause i want them to shoot at each other even when there arent any players around

[leaden sinew]

How are they being spawned?

[dark garnet]

at the player's location. either when picking up a power-up (item) or when a cmd is ran

[leaden sinew]

You can set their target when you spawn them in then

[dark garnet]

the player could be invisible tho

or move out of the way before the skeletons target them

[leaden sinew]

You said they’re targeting skeletons though

[dark garnet]

ok how?

[leaden sinew]

^

[dark garnet]

what would i set it target to tho? would i have to calculate the closeset enemy that's in range and in view?

[leaden sinew]

Yes

You should store them in a collection

Then loop over those

[dark garnet]

[queen plank]

How tf does this "Diamond Pickaxe".replaceAll("^[\\w]", "") return iamondPickaxe?

and "Diamond Pickaxe".replaceAll("[\\W]", "") return DiamondPickaxe

Isn't D a part of \\w or wat

[dark garnet]

what about after they kill that target?

and there arent any other target in-range until an enemy skeleton walks in front of them

[dusky harness]

because \w = word (letter, number, underscore) and \W is the opposite

D is a "word" and is not a "word"

so the first one removes the D, and the second one removes the non-word

[dark garnet]

LivingEntity#hasLineOfSight(Entity) says

This uses the same algorithm that hostile mobs use to find the closest player.
does that mean it also takes into account invisibility, gamemode, etc...?

[dark garnet]

ok i fixed everything by just using a bukkitrunnable to check the target every second for all the spawned mobs (which i hate)

[leaden sinew]

@dark garnet
Could you explain everything you are trying to do?
It might help me understand how to help more

[dark garnet]

since ive got it working (using runnable, i dont wanna use one if possible) ill show a video

[dark garnet]

how do i override a minecraft command? specifically when registering my own command

cause when i use Bukkit.getPluginCommand("enchant"), it returns null

[dark garnet]

all the forums say to PlayerCommandPreprocessEvent, but im not sure what to do with it besides cancelling the mc version of the cmd

[dense drift]

try to unregister the command by deleting it from the command map

[dark garnet]

command map? 👀

[dense drift]

Yeah it is a class and has a Map<String, Command> field named knownCommands iirc

[queen plank]

It is replaceAll though?

Shouldn't that remove all letters in the first one?

Why only the D

[dusky harness]

No, because you told it to only start from the beginning

so it sees one D (as specified in the regex), and since it can only start at the beginning, it stops

if you remove the ^ (which means to start at the beginning), it works how you want it to

https://regexr.com/ <- helpful website, also has a nice cheat sheet

and the same goes for your second regex

[queen plank]

I placed the ^ before the [ by mistake...

Bruh

[dusky harness]

the [] isn't needed either

[queen plank]

Oh

[dusky harness]

that's for like [abcdefg] so that you don't have to put it in a group like (a|b|c|d|e|f|g)

[queen plank]

Ahh

I see

I understood it as all "collections" (like \w) has to be in []

[dusky harness]

oh

yeah I think it's basically (?:a|b|c|d|e) but shorter and easier (into [abde])

OH and it has ^

so all characters besides abcde

I forgot about that

so like [^abc] will match every letter except for a, b, and c

regex can be pretty fun 😌

[queen plank]

Very...

[dusky harness]

there should be like a website for regex puzzles

lol

[queen plank]

Yeah lol

[dark garnet]

@queen plank i think you'll find this useful: https://regex101.com/, i use it all the time

[dark garnet]

WordlEx

it could give u start and end words then ask u how to get the end word via regex (from start word) (it replaces matches with "" [empty])

example: start: boat, end: oa, answer: b|t (ok maybe it'd have to be different so its actually hard)

[trail burrow]

I finally fixed my github so I can push and pull, do I select all in commit tab or just the class files?

[dusky harness]

all
later you can learn what to put in the gitignore

intellij also has a gitignore generator

or maybe its a plugin

i have gittoolbox 🤷

anyways just post it on github and we'll see

[trail burrow]

I use intellij and I updated all that has changed, I have many that is Unversioned files

[dusky harness]

do you have a .gitignore file

[trail burrow]

I would assume

[dusky harness]

post it on github

select all files

[trail burrow]

there is a .git folder

[dusky harness]

yes, that is the git repository

[dusky harness]

post it on github and I'll show you how to setup the gitignore

[trail burrow]

I think the unVersioned files are because on how I uploaded the first files

[dusky harness]

open intellij terminal and type git add .

git rm -rf --cached .
git add .
git commit -a -m "Cool Commit"
git push --force

just copy and paste these lines

later it's either ```
git commit -a -m "Cool Commit"
git push

but for now just copy and paste those four lines into the terminal

[trail burrow]

a forced push is the finial thing that fixed it

[dusky harness]

if it worked then send github link plz

[trail burrow]

https://github.com/Ironic8b498/Autorank

[dusky harness]

so seems like you don't have .gitignore so if you want you can create a file .gitignore in your root project directory and add: ```
.idea/
target/
*.iml

Then in terminal type: (in order) ```
git rm -rf --cached .
git add .
```and then from here it'll be like any other commit and push - press Control K (or go to Commit tab if you changed keybinds), select all of the modifications/files, type in a commit message and `Commit And Push`

just letting you know how to do this now for future projects

IntelliJ or a plugin of intellij can also generate .gitignores but I won't go into that right now

[trail burrow]

thanks, I might be able to fix my other repos, will work on them tomorrow

[dusky harness]

https://github.com/dkim19375/DkimCore/blob/master/.gitignore
Here's just the first repo I saw of mine - it's not maven but you can see where the gitignore is and how it's setup (and how I also have .idea/ in there)

atm cloned your repo and building it rn

[trail burrow]

I had .gitignore file before I started this repair they got remove in some of the commands I ran to fix it

[dusky harness]

Ok I think I know why

you had an extra .

at the end of the relocation

actually that should still work though

try without the dot

also you should be getting two jars: ```
Autorank-5.1.6.jar
original-Autorank-5.1.6.jar

[trail burrow]

I uploaded the unversioned files and everything looks normal

[dusky harness]

if you follow this then it should work well

and you can delete world.iml I think

not sure what that's for

[trail burrow]

do I need .gitignore

[dusky harness]

you should

it makes sure that some files and folders are excluded from git

caches and ones that are specific to IDEs should usually be excluded

.idea = IDE stuff
target = cache
*.iml = IDE stuff

[queen plank]

Already got linked one by Kotlin =, thanks though! 🙂

I'm trying to spawn an item frame on the block face that the player click. I currently have this code but the item frame seems to spawn a bit like it feels like randomly all over the place. Why lol?```java
public void onClick(PlayerInteractEvent event) {
if(event.getAction() != Action.RIGHT_CLICK_BLOCK)
return;

Location l = event.getClickedBlock().getLocation();
ItemFrame f = (ItemFrame) l.getWorld().spawnEntity(l, EntityType.ITEM_FRAME);
f.setFacingDirection(event.getBlockFace());
}

[dusky harness]

Wdym all over the place?

[dense drift]

spawnEntity spawns the entity with a random offset I believe

[queen plank]

That explains a bit. Because sometimes the item frame just decides to move one block over.

Hiya. Been trying to make a small plugin for Halloween. Want to create a few animal corpses and have them lie around sideways. Pretty much like this: https://imgur.com/a/HeQ6X6L
Thought maybe setPose(EntityPose.DYING) would be what I'd need but that has no effect.

I'm starting to wonder if it's even possible and if so.. how? 🤔

[merry knoll]

does it?, i am pretty sure i did an implementation that depended on it being the exact location i enter before

[dense drift]

It might have been spawnItem then

[dusky harness]

dropItemNaturally does have a random offset
but also remember that .0 x and z are in the corners of the blocks, not the center (messed me up before, I was so confused)

Anyone know how to convert a bukkit player to a worldedit player using the 6.0 WE API?

this works in the v7.2.x but for some reason BukkitAdapter is not a public class in 6.0

[broken elbow]

@sonic quartz I believe this is what you're looking for

[dense drift]

let's say I need a List#forEachIndexed method that gives you access to each item as well its index trough a BiConsumer<T, Integer> or something like that. Would there be another way to skip to the next element, like you would use continue; in a normal loop, in another way that by using return;?

[lyric gyro]

huh?

what

[dense drift]

public <T> void forEachIndexed(List<T> list, BiConsumer<T, Integer> consumer) {
  for (int i = 0; i < list.size(); i++) {
    consumer.accept(list.get(i), i);
  }
}```

```java
forEachIndexed(list, (element, index) -> {
  if (element does not meet condition) {
    return; // skip to the next element
  }

  // rest of the code
})```

This would work like this, I was wondering if it is possible to skip an element without using `return`

What I want to do with this method, is to avoid a lot of for loops with an index i

[lyric gyro]

that's dumb

you still need a variable for the index regardless

you just called it index in this case

[dense drift]

yeah but it is not defined explicit for each individual loop

for (int i = 0; i < list1.size(); i++) {
  var element = list1.get(i);
}

for (int i = 0; i < list2.size(); i++) {
  var element = list2.get(i);
}

for (int i = 0; i < list3.size(); i++) {
  var element = list3.get(i);
}```

https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/for-each-indexed.html 'source of inspiration'

[lyric gyro]

i don't see how that is different than

forEachIndexed(list1, (element, i) -> {
});

forEachIndexed(list2, (element, i) -> {
});

forEachIndexed(list3, (element, i) -> {
});

[dense drift]

I prefer it over a normal for i loop in this case

[lyric gyro]

well as I said, that's dumb, but you "continue" by returning, because that return exits the consumer function, not the loop, thus skipping to the next element; the downside is you can't break out of the loop without external state (or.. throwing an exception)

[dense drift]

I was hoping I miss something and return is not the only option to skip an element thanks emily

[lyric gyro]

it is in fact the only way

[dense drift]

yeah I know

[lyric gyro]

with that abstraction there is no "loop", it's just a function that takes a T and a number, that's all it sees

[sonic quartz]

is there an easy way to get the player who activated RedstoneBlockEvent?

I thought about using PlayerInteractEvent to save the player to a hashmap and then use him in RedstoneEvent but It will probably cause problems when handling several players doing the same thing simultaneously

I realized that I can't event use Hashmap

[lyric gyro]

I don't think it's an easy thing to do reliably

I think Sponge does it or something similar like who pushed a piston, and it's incredibly complex, but it can do things that a bukkit plugin can't given it's basically just a mod

[stuck hearth]

You could check Griefdefender to see if Blood tried to reimplement it in his plugin.

I say this because he wrote the notifier system you're referencing in Sponge

[errant pilot]

ahh crap yeah

deleted it, just the anvilgui shade now

[dusky harness]

and you reloaded the maven config thing?

I'm not sure what it's exactly called

but intellij should show like a reload button

[errant pilot]

oml refreshing fixed it

thanks for the help, havent used APIs alot lol

[dusky harness]

👍 np, just make sure you always refresh (it should pop up whenever you modify the pom.xml)

[grand zodiac]

I have this config file for my Bungeecoord plugin, when reading the file, how can I make the plugin store server1, server2, and server3 as seperate values, rather than storing [server1, server2, server3] as one value?

Sorry if that makes no sense I'm not really sure how to word it

[lyric gyro]

how are you saving the config?

[grand zodiac]

    private File file;
    public static Configuration configuration;
    @Override
    public void onEnable() {
        getLogger().info(ChatColor.translateAlternateColorCodes('&', "&a&lMATCHMAKER &8&l» &7Plugin enabled!"));
        registerCommands();

        file = new File(ProxyServer.getInstance().getPluginsFolder() + "/Matchmaker/config.yml");
        // Tries to create & load the file.
        try {
            if(!file.exists()) {
                getDataFolder().mkdir();
                file.createNewFile();
            }
            configuration = ConfigurationProvider.getProvider(YamlConfiguration.class).load(file);
            configuration.set("group1", "[server1, server2, server3]");
            ConfigurationProvider.getProvider(YamlConfiguration.class).save(configuration, file);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }```

[icy shadow]

...

lol

[grand zodiac]

like that

[grand zodiac]

I take it this is a bad way of saving a configuration?

[icy shadow]

funnily enough if you save a string, it will save that string

use a list object instead

[grand zodiac]

oh right good point 🤣

thanks

[icy shadow]

np

[grand zodiac]

as in an array or?

[icy shadow]

any list-like object

but given that i said "list", i was really talking about list

not arrays

[stuck canopy]

I have a list of numbers
and I wanna get x amount of unique numbers from the list
how can I do that

[dusky harness]

Make the list into a set
Make a for loop and put the elements in a new set or list

Also randomize

I forgot

Randomize the set before you loop it

Google like randomize collection java

[leaden sinew]

Hmm

[broken elbow]

why make it into a set if you're already creating another set

[dusky harness]

true

[broken elbow]

there's multiple answers to this question. But yeah most of them will include sets. You can do what dkim mentioned but instead of converting the list to a set, just loop thru the list directly and add the elements to the set until the set size is whatever you want.

[dusky harness]

I wasn't really thinking

but i said set bc it doesn't have duplicate

but i forgot about the ordering thing

[stuck canopy]

just Shuffled the list using Collections.shuffle() method and just got the x amount of beginning numbers of the list

[broken elbow]

[stuck canopy]

        Collections.shuffle(old);
        List<Integer> newlist = new ArrayList<>();
        for (int i = 0; i < x; i++) {
            newlist.add(old.get(i));
        }```

[broken elbow]

umm. that will not guarantee you the numbers in there are different tho. you could have duplicates

[stuck canopy]

the old list doesnt have any duplicated numbers

thats why I wrote "in order"

[broken elbow]

oh... well then java has a sublist method. if all you needed is n elements from another list.

[broken elbow]

you did?

[dusky harness]

🥲

[broken elbow]

I can not find that

[stuck canopy]

how so? never used a sublist

[stuck canopy]

I mean in the code

[broken elbow]

oh. right

[sonic quartz]

How do I change level or duration of the potion effect in potion meta of a tipped arrow itemstack?

I want to get arrows just as they are in creative inventory. Can I get them with proper names, duration and lore?

without using addCustomEffect

[stuck canopy]

you can probably do that by using ProjectileHitEvent

[proud pebble]

setBasePotionData?

[robust flower]

hmm, I will probably be the 549687815 person asking this, but how can I generate a server jar (with shaded net.minecraft in it) of version 1.19+? And no, I don't want to use mavenLocal for this, I'm not building a project, I'm experimenting with classes and decompilers

[hoary scarab]

Add --remapped flag to when you run build tools.
Or just download it from the maven repo

[dusky harness]

paperweight ftw :(

or

sponge thing if you don't want spigot

[robust flower]

so paper is no more?

[dusky harness]

wdym

no paperweight is a thing

sponge also has a gradle plugin

but it doesn't include paper and spigot

I'm experimenting with classes and decompilers

wait what

ok I think I misunderstood

[robust flower]

yeah

[dusky harness]

I thought you meant mc internal

I don't understand

[robust flower]

well, I want the compiled code of net.minecraft classes bundled together with Spigot (or preferably Paper) in a jar file

[dusky harness]

Paperweight - I'm not exactly sure where the jar is stored but I assume somewhere in the build folder

hm I can't find it

oh found it

.gradle/caches/paperweight/ivyRepository/io/papermc/paper/paper-server

I'm not sure exactly what you want

since that's basically a maven repository

[robust flower]

is that paper + vanilla in a single jar?

[dusky harness]

yes

buildtools can also do it but without paper

[robust flower]

how can I build the server jar using paperweight then?

[dusky harness]

https://github.com/PaperMC/paperweight-test-plugin
when you reload gradle it'll run all the stuff

and read the readme

[robust flower]

I don't understand how paperweight-test-plugin related to paperweight, nor why I would need paperweight-test-plugin to have the paper server jar, am I missing something? Is this some kind of "hack" to get that jar?

[dusky harness]

it's an example

of how to use paperweight

[robust flower]

I'm not building a project
Nor am I using Gradle, Maven, or any build tool for that matter

I have literally 0 code to be compiled in my hands

[dusky harness]

I guess you could try looking at buildtools source code

and see how that works

well actually

without a build tool you can't deobfuscate it I don't think

assuming you want it deobfuscated

[robust flower]

but I need exactly the obfuscated code

[dusky harness]

then download from minecraft.net

or papermc downloads and run the server to get the jar

https://www.minecraft.net/en-us/download/server

Minecraft for whatever reason has a 1 page load ratelimit 👍

for me

you could also download the paper jar, run the server, and go to versions/1.19.2/paper-1.19.2.jar

[dusky harness]

actually this isn't obfuscated at all

just checked

I'm assuming it uses spigot mappings

[dusky harness]

what's the issue?

[icy shadow]

kotlin

[heavy maple]

my b didn't mean to press enter after just that

so this is the error

[21:25:49 WARN]:  at [Source: (String)"Hat(id=test1, material=FEATHER, displayName=Unnamed, lore=[1, 2, 3, 4, 5], modelID=10000, enchants=[MENDING:1, PROTECTION_ENVIRONMENTAL:4, DURABILITY:3])"; line: 1, column: 4]
[21:25:49 WARN]:     at FruityHats-1.0-SNAPSHOT.jar//com.fasterxml.jackson.core.JsonParser._constructError(JsonParser.java:2391)```

[robust flower]

it could be worse, it could be java

[dusky harness]

I don't think you can read the value as Hat in the deserializer since that's the deserializer

wait

nvm

ignore me

lol

[heavy maple]

that's where im kinda lost lol

[dusky harness]

wait

don't ignore me

[heavy maple]

after that point im not sure where to advance to

[dusky harness]

yeah that's for when the deserializer is registered

[robust flower]

Could we see the whole stacktrace? Because with what you have posted, seems like your problem is elsewhere in the code...

[dusky harness]

so basically I think this is what's happening:

1. it tries to deserialize a Hat
2. the deserialize method calls readValue for Hat
3. repeat

[heavy maple]

yeah sure no problem uno sec

[dusky harness]

note that I've never used jackson before

and all I know about it is that it's a JSON library

so I may be very wrong

and I think I am very wrong

so I think you should be ignoring me

yeah ignore me

lol

[heavy maple]

https://pastes.dev/Vc1mG3FnOB

[robust flower]

oh I think I get it, Jackson is complaining that you gave it this, but this is not a JSON:

Hat(id=test1, material=FEATHER, displayName=Unnamed, lore=[1, 2, 3, 4, 5], modelID=10000, enchants=[MENDING:1, PROTECTION_ENVIRONMENTAL:4, DURABILITY:3])

[dusky harness]

I agree

[heavy maple]

i kinda just went along with this guide 😛
https://www.baeldung.com/kotlin/jackson-kotlin

[robust flower]

yup I was right, see, I made a small, reproducible snippet

fun main(args: Array<String>) {
    val jackson = ObjectMapper().findAndRegisterModules()
    jackson.readValue<Map<String, String>>("TestTILO(dsadasadasdadsa=\"dsadasdas\")")
}

prints

Exception in thread "main" com.fasterxml.jackson.core.JsonParseException: Unrecognized token 'TestTILO': was expecting (JSON String, Number, Array, Object or token 'null', 'true' or 'false')
 at [Source: (String)"TestTILO(dsadasadasdadsa="dsadasdas")"; line: 1, column: 9]
    at com.fasterxml.jackson.core.JsonParser._constructError(JsonParser.java:2391)```

So your fix is: give JSON parsers valid JSONs 😉

[heavy maple]

big brain i like it

OR OR

hear me out

use the actual serializable option for configs amirite
https://i.imgur.com/f07UXRQ.png

[dusky harness]

different purposes

that's for config

jackson is usually for data

[heavy maple]

yeah i used jackson (atleast the object mapper) for writing and reading to a file

hey, i wan't to learn minecraft plugin development, where do i start?

Depends on the video I guess.
For all I know you're looking at cat videos. (Pro tip: cat videos are not up to date)

[warped sail]

im using a bungeecord plugin to store data for every player in a map. is it possible to add placeholderapi into the plugin on bungee, and create a separate expansion for the spigot servers to get data from said bungee? would this have any major performance impacts?

or should i just add mysql support and slap the plugin onto every spigot server? i would still like to know how to do the above though.

[warped sail]

codedred or kody simpson i guess

i hope you know a bit of java, though.

[dense drift]

You can not run papi in bungee

[warped sail]

i am aware.
the bungee placeholderapi expansion is a thing, though.

any tutorial on how that works?

[broken elbow]

it uses plugin messaging. spigot offers you a way to transfer players by just sending a message to bungee

[dusky harness]

also note that plugin messaging is only useful in certain scenarios

since it requires a player on both the receiver and sender server

[broken elbow]

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

[dusky harness]

yeah and it also gives you some specific stuff like PlayerCount which is nice

[forest jay]

I have a item, and I want it to show the pickup motion towards the player, but not go into the inventory. Anything I can use to do this? I tried to remove it from the inventory after picking it up but that made it flash if there was a open slot in the hotbar which I don't want

[dense drift]

you can use packets to play the pickup animation

https://wiki.vg/Protocol#Pickup_Item

[forest jay]

I have no clue how to do that. Should I google it?

Ah

I will take a look, thanks

[dense drift]

packets are game internals, spigot just offers an api for some of them

[dusky harness]

https://github.com/dkim19375/Bedwars/blob/master/plugin/src/main/kotlin/me/dkim19375/bedwars/plugin/manager/PacketManager.kt#L96-L105

this is how I did it

it's not in java though

[dense drift]

https://www.spigotmc.org/resources/protocollib.1997/ this is a library that you can use to use packets easier

[dusky harness]

@forest jay and use https://github.com/dmulloy2/PacketWrapper/blob/master/PacketWrapper/src/main/java/com/comphenix/packetwrapper/WrapperPlayServerCollect.java

you don't have to copy the class - in fact I didn't - but you can see an example of the usage

[forest jay]

thanks!

[forest jay]

Yeah I have heard of it

[dusky harness]

it uses protocollib btw

[dense drift]

packetwrapper is useful

[dusky harness]

very useful

usually wiki.vg isn't needed with packetwrapper for basic things like this

@forest jay if you do use packet stuff in the future, https://wiki.vg/Protocol is very helpful for documentation (and then you can refer to PacketWrapper to see how it's implemented in ProtocolLib since ProtocolLib has some utilities that PacketWrapper uses)

[forest jay]

yeah, I have tried to use packets before, went right over my head lol

[dusky harness]
