[lilac dagger]

they should work just fine

they'll have the same internal and therefore they'll be stackable

[lost matrix]

In that case you should store custom data in your ItemStack, and check if the interaction ItemStack has this custom data.

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[lost matrix]

Dont store ItemStacks and check for .equals() or .isSimilar()
It will often times be messed up by small differences like durability or the name.

[surreal wind]

ok

[lilac dagger]

plus mutability might give you weird bugs somewhere in the code

[wary harness]

What version was e.getEntity().getItem() added to ExpBottleEvent

I ask for backwards compatibility

[lilac dagger]

you can skim through spigot api to see

see which of the abstraction has getitem

[wary harness]

like what go to each version of java docks?

[lilac dagger]

yeah

[wary harness]

lol

[lilac dagger]

or just lower your maven version till it stops working

[wary harness]

is there no any logs or something were we could check when was something added

[lilac dagger]

probably on the repository

[tepid flicker]

does anyone know how I do this? https://www.spigotmc.org/threads/how-to-build-a-gradle-project.592728/ I need to build from a plugin's gradle

Like anyone to specify in detail

and what program I need to use

[lost matrix]

If ./gradlew build isnt enough to compile it, then you should not touch it

[tepid flicker]

sorry to ask this but where do I run the command?

[abstract iron]

    @Override
    public void onEnable() {
        ItemStack pooScraper = new ItemStack(Material.WOODEN_SWORD,1);
        ItemMeta pooScraperMeta = pooScraper.getItemMeta();
        pooScraperMeta.setDisplayName("§6Poo Scraper");
        pooScraperMeta.setLore(List.of("The legendary weapon of old"));
        pooScraper.setItemMeta(pooScraperMeta);

        ShapedRecipe recipe = new ShapedRecipe(new NamespacedKey(this, "Scraper"), pooScraper);
        recipe.shape("CCC","CXC","CCC");
        recipe.setIngredient('X', Material.WOODEN_SWORD);
        recipe.setIngredient('C', Material.COCOA_BEANS);

        Bukkit.addRecipe(recipe);
    }

Hey learning how to mess with custom recipies rn
how do I specifically make it use a full durability wooden sword for the recipe

[tall dragon]

pooScraper? 😂

[abstract iron]

Cause I dont want them to be recrafting the same sword over n over

[abstract iron]

baldurs gate reference shush

[lost matrix]

RecipeChoice.ExactChoice is the best you can do right now.
But this limits the choice to exactly the ItemStack you put in.

[wary harness]

Could I extend ExpBottleEvent and make custom one

[tepid flicker]

im very new to plugins and I don't want to waste anyones time

[wary harness]

which I could my owne method of adding itemstack

?

[tepid flicker]

but I dont know where to put the command

[lost matrix]

Run the command in your terminal while being in the projects root folder.
Shift + right click -> open terminal here

[tepid flicker]

in the core folder?

https://github.com/IntellectualSites/PlotSquared

[lost matrix]

I dont want to discourage you, but compiling this plugin wont help you getting started with development.
This plugin is open source to help other developers. If you are a user, then you should consider just buying the plugin and supporting the devs work.

[tepid flicker]

yeah I was afraid I'd get this response

[abstract iron]

        ItemStack plainWoodenSword = new ItemStack(Material.WOODEN_SWORD, 1);
        RecipeChoice.ExactChoice woodenSwordChoice = new RecipeChoice.ExactChoice(plainWoodenSword);
        recipe.setIngredient('X', woodenSwordChoice);

@lost matrix so something like this?

[lost matrix]

Yes, but keep in mind: This will also block out any modifications like lore, enchantments, name etc

[tepid flicker]

could you please tell me which one is the projects root folder

[tall dragon]

bassically the one where you see all the files from gradle.

[abstract iron]

hmm right okay so if its renamed it doesn't work still got it
has to be the super exact one

[lost matrix]

Here are some things to search for:

• How to install git
• How to clone a github repository to my computer
• How to compile a gradle project

Research away

[tepid flicker]

thanks

[lost matrix]

Im currently contemplating on a more granular system for 1.20.5 when the components are introduced.
It might allow for better predicates.

[tacit arrow]

cket

[tepid flicker]

oh so you run the command in the git?

[lost matrix]

#help-development message

[tepid flicker]

Everything went well except I can't find the gradle.git

https://github.com/IntellectualSites/PlotSquared/tree/main

[lost matrix]

There is none. gradle.git is not a thing.

[tepid flicker]

so what file do I need to clone using git?

[lost matrix]

I wont give any more specific steps for this.
Tell me what you researched and what you need help with. Ill gladly answer general programming questions.

[tepid flicker]

Like most Spring Getting Started guides, you can start from scratch and complete each step or you can bypass basic setup steps that are already familiar to you. Either way, you end up with working code.

To start from scratch, move on to Set up the project.

To skip the basics, do the following:

    Download and unzip the source repository for this guide, or clone it using Git: git clone https://github.com/spring-guides/gs-gradle.git

    cd into gs-gradle/initial

    Jump ahead to Install Gradle.

``` I can't find a similar file in the plotsquared similar to this https://github.com/spring-guides/gs-gradle.git

[tall dragon]

thats because its not a file

thats the repo itself

[tepid flicker]

do I use this? https://github.com/IntellectualSites/PlotSquared/tree/main/gradle

[lean pumice]

Who could come to the phone to give me a bug that I don't know how to solve?

[tall dragon]

no

[tepid flicker]

and copy that?

Im unsure what to copy

[echo basalt]

isn't this as simple as cloning the repo on intellij and pressing build

Could be that the version is invalid

[late sonnet]

or maven cache issues

[tepid flicker]

thanks

[wide coyote]

what jar

[echo basalt]

that's a damn old version of authlib iirc

[tepid flicker]

now that I have copied it, what is the next step that I need to research?

[tall dragon]

how to compile it

[tepid flicker]

so I compile it in the git?

[wide coyote]

probs from 1.5.2 lol

[tall dragon]

yea in the main directory

[echo basalt]

solid chance yeah

[wide coyote]

ah man i am going insane

i swear to god i've seen some message about authlib

[tepid flicker]

it says I just put the command" gradlew.bat build" into the git? but it doesn't work

[flint warren]

i did send an authlib but i deleted them

[wide coyote]

ah

thats rude

[flint warren]

😦

[tall dragon]

./gradlew build

[wide coyote]

anyway use system scope and set the systemPath to the path to authlib jar

[flint warren]

nono its fixed

[echo basalt]

am I tripping or is crafty compiling without an ide

[wide coyote]

aight

[tepid flicker]

no directory found it says. also is the main directory in the git command thing

[tall dragon]

i think they are yea

[echo basalt]

or just don't use a 10 year old version of authlib?

[wide coyote]

that works too

[flint warren]

i mean it works

[tepid flicker]

so I put the command in my ide?

[tall dragon]

do u have intellij?

[tepid flicker]

yea

[tall dragon]

open the project in intellij

[tepid flicker]

the clone?

[tall dragon]

jup

[tepid flicker]

where is the clone in my computer

[tall dragon]

-,-

wherever u ran the clone command i suppose

[slender elbow]

just pay for the project

[tepid flicker]

I opened the whole files in intellij including the other files(every file that was in the hub)

[tepid flicker]

https://tenor.com/view/cartoons-fox-poor-gif-10729250

🥲

[slender elbow]

https://tenor.com/view/image-pic-pic-perms-image-perms-gif-22063115

[tall dragon]

then u should be able to double tap ctrl, a "run anything" prompt should come up, where u can input ./gradlew build

[tepid flicker]

works but how do I get it into a jar?

[tall dragon]

it made one

[tepid flicker]

gradle bin zip I got

[echo basalt]

jesus this is a 5 second thing

[tall dragon]

??

[echo basalt]

click here, paste the git url and it'll open the project for you

Then on the far right click on gradle and run build

that's it

[tall dragon]

pretty sure they just cant find the output jar now

;d

[echo basalt]

Gradle makes a build folder

The jar's on the libs folder

[tepid flicker]

I dont have a spigot folder :/

[echo basalt]

that's my module

it's like a sub project

PlotSquared uses modules too

[tall dragon]

yours will be called Bukkit

[tepid flicker]

the only thing in it is the src

and build.gradle.kts

[tepid flicker]

cant find tasks folder

[tall dragon]

then it has not compiled successfully

[echo basalt]

gradle my beloved

[tall dragon]

2 minutes!

[tepid flicker]

what is gradle daemon lol

wait

I think I got it

thanks for the help but the plugin doesn't work :/

but I am really thankful for the time you guys spent helping me

[lilac dagger]

is that normal for gradle?

[echo basalt]

it likes to build caches

Usually the first build of the day takes minutes and any following ones take seconds

[slate surge]

Thnx, adding a wait of 20 ticks fixed it, it was just that the server was shutting down before the player gets transferred to another server

[lilac dagger]

ah that makes sense

wait, what are the advantages of gradle?

i'll use chatgpt

[minor garnet]

does anyone know how rotate the head of an armor stand based on 2 vectors, one for direction and one for inclination ?

[eternal oxide]

you mean pitch and yaw?

[minor garnet]

not necesarilly, those blue and green line are diferrents vectors, let me show a video

[eternal oxide]

why do you have two vectors?

[minor garnet]

you will understand in the video

[lilac dagger]

well, do you want to sum the 2 vectors and make the head look in the direction the vector is pointing if the head is the origin?

[eternal oxide]

there is no tilt on a head

tilt = roll

[slate surge]

Why no one uses artifacts builder?

[lilac dagger]

oh so one vector is for roll?

[slate surge]

Maven>>>Gradle

[echo basalt]

Personal preference

Man came here and decided to choose violence

[tender shard]

why

[lilac dagger]

oh

[minor garnet]

basically it is a cube that rotates, and one has a steering phase and the other an inclination phase

[lilac dagger]

you can transform the vectors into blockfaces and then apply rotations based on the blockfaces

the magnitude can be transformed into the initial rotation speed

[eternal oxide]

I have no idea what that video was showing

[echo basalt]

wtf is youtube recommending me

[minor garnet]

basically it is a physics cube that rotates, one has a vector on one side and the other side of the face which involves the orientation and direction

basically it's a physics cube that rotates, one has a vector on one side and the other side of the face that involves orientation and direction, irrelevant, think about the cube, I want to make the head of the armor stand have a block and that its rotation would fit inside this cube

[minor garnet]

does anyone have an idea what I can do?

[rapid vigil]

Which way is preferred for registering a listener in another class https://paste.md-5.net/yanabimoma.java

[tender shard]

ah

[tender shard]

i would always register the listener in the class that created it. a listener instance shouldnt be responsible to register itself imho

[lilac dagger]

i have an idea of phisics in mind but it's not that same as yours so i can't really help

[eternal oxide]

I like the self registering, but it's not the correct way

[tardy delta]

listener shouldnt be aware of its surroundings

[rapid vigil]

aah alright ty :>

[minor garnet]

I would just need to know if somehow I could fit those 2 vectors with a rotation in vector3f

[slate surge]

Ez make all listeners in one class lol

[lilac dagger]

what does the vector 3f in an armor stand stand for?

[echo basalt]

3 floats

[slate surge]

aka

[lilac dagger]

if it's x, y, z rotation then you should have a good idea about how you can fit your vectors

[slate surge]

3 floating people

[lilac dagger]

you just need a formula to see how much of the vector can rotate your cube

[minor garnet]

setHeadPose

[lilac dagger]

i think i worked with it, i think it's in radians?

is there anything you struggle with? is it the formula to convert a vector into one of the vector 3f coordonate?

the direction vector does not convert easily into a head rotation

you can only infer based on the direction how the head rotates

i also assume when your objects collide you'll want to change the head rotation

how to remove the original minecraft enchantment lore from the item?

The class is Whatever

It has a field named whatever of type int

bad example you never initialized the final int meaning their will be a compile time error

[lost matrix]

.txt best config format, dont change my mind

[echo basalt]

if your input is invalid the entire spreadsheet changes to red

and all text colors change to the background color

so you can see it's invalid

also if you type "clear" in any of the fields it clears the whole config

lol

[ocean hollow]

what do I need to enter in Damageable#setDamage. Does it mean how much durability or how much is left? or does it damage the item for that number?

[lost matrix]

setDamage, sets the damage on the item.
damage on an item means that it is damaged for that amount.

[ocean hollow]

thanks

[lilac dagger]

0 up to maximum durability

the maximum is held by material

[lost matrix]

*for now

[forest moss]

How can i make "event.setTotalCookTime(1)" also cook or consume the charcoal properly? because, for example, 64 iron and 64 coal consume 1 carbon for every 1 iron ore? @EventHandler
public void onFurnaceStartSmelt(FurnaceStartSmeltEvent event) {
if (autoSmeltEnabled && event.getBlock().getState() instanceof Furnace) {
event.setTotalCookTime(1);
}
}

[lost matrix]

This is basically a property of the ItemStack which is put into the Furnace.
Those values are currently hard coded.

Something something fuel value

[ocean hollow]

why does it give me this?

[lost matrix]

What... try allocating a String variable and see if this changes the warning

[ocean hollow]

?

[wet breach]

are you using @PrintFormat annotation?

[ocean hollow]

no

[wet breach]

what is the symbol on the left?

[ocean hollow]

?

[wet breach]

probably shouldn't use that

since you can't guarantee it not being null

and you are saying its not null

well given you don't check

[ocean hollow]

so if I add NotNull it will also throw an error

[wet breach]

no, but if it that section is in fact null, using that annotation will hide the problem that is the case

and misleads you on the issue because it starts throwing trap errors

now your annoation is useless if you do that, anyways the purpose of such annotations is mostly for api's where you are saying this thing here is not null and should never be null and if it is we have big problems 😛

shame the IntelliJ tries to get everyone to use it without knowing its purpose

but anyways, your unsubstituted expression is happening because of a string

"Unsubstituted expression" means that IntelliLang isn't able to analyze the string being passed/assigned to a variable because it's neither compile time constant nor annotated with an @Subst annotation. There's also an option in the inspection configuration (Settings -> Errors -> Pattern Validation -> Validate Annotated Patterns | "Flag non compile-time constants expressions") that allows to exclude such expressions from static checks.

this also relates to @PrintFormat annoation as well if something were to pass something to it

[forest moss]

and then how can I do it

: (

[lost matrix]

Hm, either you wait for 1.20.5 to come around or use nms

[granite owl]

can someone redirect me to the documention for commands? i know that i can inherit some command base class to create a new instance and register the command at runtime

which allows for fancy things like auto completion

but its like 3years ago i did it and i lost my old projects

[ember dew]

What's the procedure for specifying a custom directory such as "mod/config/errors.yml" instead of just putting it in its default directory(/mod/errors.yml)

        customConfigFile = new File(getDataFolder(), "custom.yml");
        if (!customConfigFile.exists()) {
            customConfigFile.getParentFile().mkdirs();

If you want to keep using saveResource() then simply recreate the subdirectory structure in your jar

[hollow vessel]

when PlayerFishEvent is called? Because when I'm trying to figure it out i can't

or what is the best event to do some actions when player uses fishing rod and bobber is on the ground

[lost matrix]

For all of those cases

[ember dew]

Out of curiosity, is there a more efficient/better way of handing custom config files

[tardy delta]

ini file

[lost matrix]

Its all a preference. I personally completely dropped the idea of including config files in my plugins.
They are all generated from classes.
But you should be completely fine with using the default spigot configuration api like that.

[hollow vessel]

it is working my bad sorry for problem

[ember dew]

So you hardcode everything, or leave it customizable ingame?

[lost matrix]

Let me find an example

[surreal wind]

how can i make a custom potion item?

[lost matrix]

Cast ItemMeta to PotionMeta and then look through here:

Im using a library called Ambrosia for this

Which i wrote

[ember dew]

Damn, okay

[echo basalt]

Not a fan of that style of config

[lost matrix]

Which part bothers you? 🙂

[echo basalt]

The fact it hides code flow

I hate anything that does runtime generation or reflection-based hackery

I worked for a server where every command and listener was initialized automagically

[lost matrix]

Serialization without reflections is an absolute nightmare

[echo basalt]

Codec 🗿

[lost matrix]

I dont use reflections or code generation for anything else than serialization

[lost matrix]

My codec uses marshalling. Which is perfectly viable imo

[echo basalt]

Im past my days of gsoning out entire pojos and praying the database knows how it works

And then crapping the bed because it faced an abstract class

[lost matrix]

Im past my days of writing my entire code twice. Once for the object itself and once to manually searilze each field.

My serializer can serialize interfaces and abstract classes

guys i tried finding if i can do brewing stand custom recipes but i cant find anything, can i make brewing stand recipes?

[lost matrix]

BrewingStands work in a unique way. iirc there are no recipes for them.

[surreal wind]

So technically it is possible it is just really hard?

[lost matrix]

I think you just tinker with the brew events

[surreal wind]

It's too advanced for me im trying to make wine

i think i will just use a crafting table recipe

[lost matrix]

Another idea:
Use barrels to ferment berries and sugar 🙂

[surreal wind]

so i put the berries inside and wait?

[wanton comet]

this public?

[lost matrix]

Pretty much. Add a hologram on top to show progress.
And spawn some particles.
Create a custom recipe for a brewing barrel.
Only those can be used for brewing then.

[surreal wind]

ok thanks for the help

[lost matrix]

https://www.spigotmc.org/threads/ambrosia-easy-to-use-storage-library-for-mongodb-files-pdc-and-redis.640405/

in 1.0.2 im releasing the yml and config api.
The public branch doesnt have it currently.
It can only be used for general serialization to files etc.

[lost matrix]

Btw this is quite advanced.
Maybe consider brewing stands for now.

[surreal wind]

dont worry i think i will be fine

the holograms are the only thing i dont know how to do

[wanton comet]

Show your code

[ember dew]

Could you give me an example, I'm losing my mind

[eternal oxide]

paper

[surreal wind]

@lost matrix It doesn't let me pass ItemStacks as an ingredient for a recipe...

[lost matrix]

You need to pass a RecipeChoice
An ExactChoice if you want it to be NBT aware (full match needed).
Or a MaterialChoice if it just needs to match the material.

You are not developing a plugin so this is the wrong channel

[surreal wind]

where do i specify the recipechoice

[lost matrix]

#help-server

[lost matrix]

You just declare a variable and initialize it with a new instance

[lost matrix]

Te make the lingo clear:

Declaring a variable:

int x;

Initializing a variable:

x = 10;

Defining a variable: (Declaring + Initialization)

int x = 10;

Creating an instance of a class (often synonymous to Object)

new SomeObj();

Declaring a variable and initializing it with a new instance of a class:

SomeObj something = new SomeObj();

[surreal wind]

ty, im new to java i only know python and c#

[ember dew]

Nevermind, I stopped being incompetent

[surreal wind]

it's way harder

@lost matrix do you know how i can make a berry bush that when it grows it gives me grapes?

[flint warren]

best way to naturally spawn entities would be to increase spawn rate and replace the entity in an entityspawnevent given a certain chance right?

but only when a grape bush grows not all berry bushes

[surreal wind]

what event is used when i right click a block?

[worthy yarrow]

Uhhhh

Don't quote me, but I believe you have to derive that from playerInteractEvent

[lost matrix]

PlayerInteractEvent

[surreal wind]

and the one that happends when an inventory pops up?

cause i want to cancel that for the brewing barrel

[worthy yarrow]

InventoryOpenEvent

[surreal wind]

ty

[worthy yarrow]

btw, spigot api in google will give you the answers to "what event does what", just try searching for (action)Event

[surreal wind]

oh

ty

[worthy yarrow]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/inventory/InventoryOpenEvent.html
This documentation specifically

[surreal wind]

how can i find out from the InventoryOpenEvent if i clicked on a brewing barrel and not any barrel?

[worthy yarrow]

Again don't quote me, but I think you check the inventory type

[surreal wind]

i tried but i can only check if its a barrel inventory

or a chest's

[worthy yarrow]

Then you're probably gonna have to get into block states

Unless I'm just wrong ofc

[lost matrix]

You need to get the holder and check if its an instance of BlockInventoryHolder.
I would honestly just cancel the PlayerInteractEvent and open my own inventory instead.

*if you want a custom inventory for that

[surreal wind]

no, i want to right click once with a berry and once with a sugar, no gui needed

[young knoll]

Why use the open event then

[acoustic pendant]

I'm trying to get the item clicked from a menu which is a head, above 1.13 works fine but when I'm in a lower version and try to click that item and check if it is the same than the item in a hashmap (Which is the same) it says that the hashmap is null I already have a method that detects the version and sets "PLAYER_HEAD" or "SKULL_ITEM" so the error only happens when the item is the SKULL_ITEM id from 1.12 and less, does someone know why this happen?

[young knoll]

Just use the interact event

[worthy yarrow]

^ , but he also needs to specify the inventory being a brewing barrel

[surreal wind]

to cancel it

how would i use the interact event?

[young knoll]

Cancel that

[worthy yarrow]

Check that the interaction is with your brewing barrel, cancel the vanilla action(s), and proceed with whatever logic you want

[surreal wind]

i cant do the checking for the barrel i cant find a block name or anything to identify the brewing barrel

[young knoll]

Well it probably identifies itself somehow

PDC maybe

[worthy yarrow]

The interaction event should be enough to return what block was interacted with

[surreal wind]

event.getClickedBlock() gives me a block but i doesnt have a name

should i compare this to the brewing barrel itemstack?

[worthy yarrow]

Right you're not checking for a name

you should be checking for a block/block type I believe

[surreal wind]

do i need to make a custom block for this to work?

[round finch]

do you mean casting?

[worthy yarrow]

Uh no, you just check if the block is a brewing barrel

[worthy yarrow]

then proceed down the line

[surreal wind]

like this?

[lost matrix]

A Block object will never be equal to a String object

[surreal wind]

ye ik

just a placeholder

[ocean hollow]

how can I iterate this values from config?

[worthy yarrow]

Now you should just be able to check for the block

[surreal wind]

i only have an itemstack of a brewing barrel should i cast it to a block and check?

[worthy yarrow]

Yk I don't even know what a brewing barrel is...

[surreal wind]

its an itemstack i made

a barrel

with a custom name

[worthy yarrow]

Mmmm

[young knoll]

You should add PDC to it when placed

[worthy yarrow]

So it's a custom block, when clicked with sugar / berry it does something?

[surreal wind]

it's just an itemstack

no block

do i need to make one?

[young knoll]

.

[worthy yarrow]

Itemstack can mean literally any material

Just do what coll said when it's placed

[surreal wind]

ok

[worthy yarrow]

It seems you are trying to make a custom / interactive BLOCK, so just continue with what you're doing now, when it's placed add pdc to the block as to maintain the fact it's a custom block

also make sure to note that these are two different functions so keep your concerns separated

[hollow vessel]

is there maybe some event like TridentThrowEvent? or i just must use PlayerInteractEvent? what would be the best event to check when player throw trident?

[young knoll]

ProjectileLaunchEvent

[hollow vessel]

thanks

[hollow vessel]

but I need to get from event player, this event doesn't have any method that returns player

is there any other event?

I need event that is called when player throw trident

[tall dragon]

ProjectileLaunchEvent#getEntity()#getShooter

[lost matrix]

You can get the ProjectileSource from the Projectile and check if its an instance of Player

[hollow vessel]

thank you very much guys!!

[granite owl]

if i want to write my commands myself without using the plugin.yml for it to create and register them at runtime, should i work with the BukkitCommand class or the CommandExecutor interface and why?

[lost matrix]

You would have to inject your commands directly into the command map.
I would probably just use an existing command api.

[granite owl]

so the plugin.yml?

there are methods to register the commands without injecting them with reflection though

from the docs i assume that BukkitCommand calls its superclass Command which registers them to the map already?

by name

[lost matrix]

If you have questions regarding adventure, then the paper discord is probably a better place to ask

[surreal wind]

guys can i add pdc to blocks?

[young knoll]

?blockpdc

[undone axle]

Learn about CustomBlockData here:
https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[young knoll]

Unless it’s already a tile entity

Then you can

[surreal wind]

is there any other way

cause idk how to use this

or just mark a block

[eternal oxide]

Sharpie

[lost matrix]

If its a TileState (Like a Furnace, Chest, Barrel etc), then they automatically have a PDC.
You just need to get their BlockState and cast it to TileState.

[surreal wind]

ok

[granite owl]

apparently i do need to get the map via reflection

should i then register it using the plugin.yml and set this commands executor instead?

[lost matrix]

You dont need the plugin.yml at all if you just throw your commands into the command map.

[granite owl]

yes

but im using reflection rn

isnt that discouraged?

[junior anvil]

how to get nms entity from bukkit entity

[young knoll]

Cast to CraftEntity and getHandle

Obligatory: why tho

[inner mulch]

is there an event for when the server is fully initialized and players are able to join?

[eternal oxide]

1 tick after your onEnable finishes

[lost matrix]

ServerLoadEvent

[inner mulch]

thanks

[junior anvil]

i wanted to set a mob's target to a random entity from a list of nearby entities that i get at a specific range

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Mob.html#setTarget(org.bukkit.entity.LivingEntity)

[young knoll]

^

[junior anvil]

yeah, i got it

List<Player> nearbyPlayers = getNearbyPlayers(entity.getBukkitEntity().getLocation(), range);
        if (!nearbyPlayers.isEmpty()) {
            Player randomPlayer = nearbyPlayers.get(new Random().nextInt(nearbyPlayers.size()));
            bossEntity.setTarget(((CraftPlayer) randomPlayer).getHandle());
        }

i hope this is right

getNearbyPlayers returns a List of players

[lost matrix]

Write an aggro system. Attack the player that does the most damage and let it cool down a bit every tick 🙂

[junior anvil]

Ooh, interesting idea

[lost matrix]

Map<UUID, Double> should be enough to track damage dealt

[echo basalt]

call of duty zombies style where it just attacks the nearest player

[young knoll]

That’s just normal mob behaviour

[echo basalt]

eh

Don't mobs have a cooldown?

[autumn ingot]

does anyone know why setTongueTarget on Frog doesn't work? i expected it to stick its tongue out at the specified mob; but its not doing anything

not sure if im misusing the method or something

[inner mulch]

how do i get the port and host of my minecraft server? (with the api)

[drowsy helm]

as in spigot api?

[inner mulch]

yes, i guess?

[drowsy helm]

Bukkit.getServer().getAddress(); but doesn't really mean much if you are behind a proxy or rerouting the port

why do you need to get it through the api?

[inner mulch]

dynamic proxy

i dont want to have it all in the config

do you know the event for when the server is disabled? is there something called after ondisable?

[drowsy helm]

if its dynamic you would probably benefit more by having some orchestrator

pretty sure onDisable is the last event called

[lost matrix]

Btw this prints the IP specified in the server.properties iirc
(which might be absent)

[drowsy helm]

if you use docker or kubernetes you can have all servers on 25565 then just use that api instead

[lost matrix]

Yeah

[drowsy helm]

yeah it does, there wont be any solid methods that give public ip

unless you ping an outside server

even still, a proxy or router could reroute the port to another external port, making any port thats given through api useless (unless everything is on the same LAN)

[torn shuttle]

I have a very important question

which fornite dance would play best with a mc model

serious answers only

[sullen marlin]

Flossing

What other dances are there even

https://tenor.com/view/backpack-kid-backpack-kid-dance-floss-floss-dance-gif-18264451

[torn shuttle]

fucked if I know, I never saw any media about it

I just want to meme with my new custom model plugin

alright as per requested by md5 I'll make a flossing animation for a showcase

md5 can I put a quote on there with you saying this dance is lit af?

[sullen marlin]

This dance is lit af

[torn shuttle]

perfect

alright off I go to make models floss

[sullen marlin]

Instructions unclear, dentists pleased with tooth hygiene

[torn shuttle]

my dentist is very happy with me

I just paid him 4k for braces

and change

[echo basalt]

mine quoted me 5k

told him to eat shit

[torn shuttle]

damn

I paid that guy 2k to quote you 8k

he ripped me off!

[worthy star]

is it possible to get the file.yml node from the key of it?

[lilac dagger]

why is file.yml a node?

[worthy star]

no i mean like

something: 'id'
```, i want to be able to get the 'something' from the 'id'

[worthy star]

a node from file.yml

[lilac dagger]

getsection .getkeys false

returns the key list

[worthy star]

its not a section

[lilac dagger]

in yml everything is a section

[worthy star]

oh

anyway

[lilac dagger]

if you are in the root just do config.getkeys(false)

[worthy star]

i mean
i have the key, but i don't have the node.. how can i get the node from the key? each node has its special key

[hazy parrot]

You get lists of key

Iterate trough it

If value == your value

[lilac dagger]

and then get the section ^

[hazy parrot]

Return that key

But tbh that design doesn't sound right to me

[lilac dagger]

i assume node = section

[worthy star]

can i get the list of sections, and check if section's key = the key i have?

[worthy star]

yea

i see some people calling it nodes

[lilac dagger]

yeah, it all depends but in bukkit they go by sections

[torn shuttle]

man it's not easy to make a steve model floss

[lilac dagger]

3d model?

or you're trying to animate the skin somehow?

[torn shuttle]

3d

[worthy star]

for(String section : config.getConfigurationSection("linked").getKeys(false)) { is the section here the path? because not really interested to test it out xd

[lilac dagger]

oh, that's nice

it should be doable

[worthy star]

hm?

[lilac dagger]

you'll get

linked:
test1: a
test2: b

you'll get test1 and testb as strings

[worthy star]

oh nice

    public static Object getSection(YamlConfiguration config, Object key) {
        for(String section : config.getConfigurationSection("linked").getKeys(false)) {
            if(config.get(section) == key) {
                return section;
            }
        }
        return null;
    }``` i got this so far

not sure if its good

[lilac dagger]

assuming the key is alright it should be good

[worthy star]

ighty thx

i'll test it

[lilac dagger]

oh wait

you might wanna consider equals when dealing with objects @worthy star

[worthy star]

what?

wdym?

ohy wait

if(config.get(section).equals() you mean?

[lilac dagger]

objects can be different and therefore == would fail

yeah

[worthy star]

can i ask JDA related things here?

[lilac dagger]

it should be fine

i tried jda but not really that familiar with it

[worthy star]

if i want to get a discord member from his id, should i use User or Member

and whats difference

[lilac dagger]

you can look into what methods each provide

i'm sure one is for some tasks while the other is for others

[remote swallow]

both will return the same thing

they just have different info as one relates to the user as a whole and one relates to then as a member in the discord

[vocal cloud]

The JDA documentation is amazing I highly suggest reading it

[worthy star]

is the member for a member in the dc server or the whole thing?

[remote swallow]

as a member in the discord

the id is the same both ways

[lilac dagger]

i just realised i can up the source compiler version to the highest while keeping the target as java 17

that's nice

i haven't tested it yet

[buoyant jasper]

can anyone help me solve problem with my plugin code its a mess

[lilac dagger]

it depends on how long the mess is

[buoyant jasper]

i tried to get another plugin classes into my plugin

is there anyway i can send the code files and you see it tell me what i did wrong

[lilac dagger]

that might be a problem, you can shade them into your plugin

unless you manually copied them into your plugin

[buoyant jasper]

i manually copied

[lilac dagger]

i don't know if i can help, it might sound like trouble from the original developer

[buoyant jasper]

i made both plugins

[lilac dagger]

you can just copy the source code into your new plugin

or have a common library and use it in either

[buoyant jasper]

i already tried to solve errors with other classes so its all connected with problems

[lilac dagger]

there's no magic button to fix incompatibility issues

[buoyant jasper]

can i send you the code tell me whats wrong

[lilac dagger]

sure

[buoyant jasper]

how can i send the project file

[lilac dagger]

verify then i guess you can zip it and send it, altho if it's large i don't think i'll be able to help you much

[worthy star]

    public static String randomString(int length) {
        String[] chars = new String[]{"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"};
        chars = String.valueOf(chars).split("");

        StringBuilder builder = new StringBuilder();

        for(int i = 1; i < length; i++) {
            builder.append(new Random().nextInt(chars.length));
        }

        return builder.toString();
    }``` is this a proper way to get a random string?

[echo basalt]

You can optimize it a little bit

Let's start by not creating a random for each iteration

That's expensive

We can also use random.nextBytes to generate a bunch of bytes in one go

[lilac dagger]

same for the string array

there's nextBytes?

[echo basalt]

public static String createRandomString(int length) {
    Random random = ThreadLocalRandom.current();

    String characters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
    byte[] bytes = new byte[length];

    random.nextBytes(bytes);

    // transform into char[], no need for StringBuilder
    char[] chars = new char[length];

    for (int index = 0; index < length; index++) {
        // clamp the byte to 0-255, then mod it to the charset length so that it doesn't go out of bounds,
        // and just wraps around
        chars[index] = characters.charAt((bytes[index] & 0xFF) % characters.length());
    }

    return new String(chars);
}

Sure it'll pick some characters more than others

Because uh

[echo basalt]

the mod

[lilac dagger]

i have this

static final char[] STRING_CHARS = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890".toCharArray();

along with this

[lilac dagger]

that's so nice actually

does it help performance that much?

[echo basalt]

Not really

[worthy star]

it worked, thx

[echo basalt]

You can fix the "some characters are more likely than others" by either making your alphabet length a multiple of 2, or just skipping the byte[] generation part entirely and generating an int for each iteration

[lilac dagger]

oh

[echo basalt]

no clue why I mod the byte it's never gonna go past its own limit

[lilac dagger]

so it has issues, i guess i'll stick to new int per each

[echo basalt]

Yea

[young knoll]

Gotta do a full random utf 16 character each time

[lilac dagger]

good luck displaying that in most contexts

[young knoll]

Hey minecraft supports it

Mostly

[lilac dagger]

when i think utf-16 i imagine looking at this

[echo basalt]

avg resourcepack

[young knoll]

Minecraft uses unifont stuffs now so it can display most of them

[rough ibex]

well, minecraft upgraded its unifont

its always used unifont

[echo basalt]

can't wait for minecraft 1.21 to release

[young knoll]

Did they use a version from like

2005 or something

[echo basalt]

change logs:

• added native kubernetes support
• rewrote the whole game in cpp
• minestom's the native server now

actually that's 1.20.6

[rough ibex]

I think they used 9.0

now it's 15

maybe before that

[young knoll]

I swear it only supported like

Base Unicode before

[rough ibex]

wdym base unicode

there is no such thing

you mean plane 0?

[young knoll]

Sure

[rough ibex]

minecraft used to only have glyphs for <= U+FFFF

plane 0, BMP

the unifont update brought Unifont's plane 1 glyphs

10000 .. 1FFFF

[young knoll]

Not even all of those worked

[rough ibex]

no, the unifont support back then was also limited upstream

[young knoll]

I remember miscellaneous symbols and pictographs never worked

[rough ibex]

only some of it

well, misc symbols & pict is plane 1

you may be thinking of Misc Symbols

2600 26ff

https://en.wikipedia.org/wiki/Miscellaneous_Symbols

[young knoll]

Is 2600-26ff not < ffff

[rough ibex]

it is < ffff

but misc symbols and misc symbols & pict are not the same block

the former is plane 0, the latter is plane 1

[young knoll]

Ah I see

Dingbats is plane 0, those also never worked

[rough ibex]

the latter has a lot of emojis

only some of dingbats

upstream unifont at the time was not complete

[young knoll]

Yeah makes sense

It’s nice having the expanded character set, even if I don’t need nearly that many

[rough ibex]

meh, I made my own font

-with these characters, before minecraft imported unifont 15

I just don't really have a name for said font.

[young knoll]

Unifont

Wait no that’s taken

[rough ibex]

the first name was EUCF

extended unicode character font

and then it was EXTD, EXTenDed

now I'm trying on Rhos but I'll likely renege

[young knoll]

I didn’t realize we now have like

100k+ private use characters

[rough ibex]

mhm

and some people still use chinese

[young knoll]

Lol

I think OR does

[rough ibex]

hypixel does

I think I might go back to EXTD

[young knoll]

Tbf hypizel only has the 6400 private use characters

But that should still be plenty so

[rough ibex]

I don't think so

[young knoll]

?

[rough ibex]

Why can't hypixel use plane 15?

[young knoll]

I don’t think you could address those back then, even with the surrogate pair stuff

Could be wrong tho

[rough ibex]

I don't think that's correct

UTF-16 works on surrogate pairs.

that's how it exists

by using surrogates to encode points > FFFF

all UTF encodings are lossless

UTF-16 can encode all 10FFFF

[young knoll]

Yeah but Minecraft just didn’t support it

[rough ibex]

why not

[young knoll]

Or at least I never saw it used before like, 1.18

[rough ibex]

Well, custom fonts only existed really in 1.13+

so it wasn't very relevant

since you couldn't retexture

but I think you could still send the actual character, it should just show as tofu

[young knoll]

Tofu

[rough ibex]

yes

https://en.wikipedia.org/wiki/Noto_fonts#Etymology

[young knoll]

I just called em a rectangle

I guess you could compare that to tofu

[rough ibex]

notdef is another name

[young knoll]

[]

[rough ibex]

I think I'll stick to EXTD

[torn shuttle]

@sullen marlin I hope you're happy with your request for the best fornite dance

[rough ibex]

now speed it up

[remote swallow]

where sound

[young knoll]

That’s still in blockbench

In game or riot

[echo basalt]

make it default dance

https://tenor.com/view/shaggy-default-dance-victory-gif-14972422

[remote swallow]

can it teach me how to dougie

[trim lake]

Can I somehow dettect if item was taken after CraftItemEvent? Im modifying results of event if item is not taken Im modifying that modified item again and I dont want to show that modified item in results slots it it is not takne. I want show modified item when is not taken as restuls to player inventory. I want to display not modified item.

[torn shuttle]

@remote swallow @rough ibex

[rough ibex]

the kids are having fun

[remote swallow]

no i want swish swish bish

[torn shuttle]

buddy I ain't an animator, I make the systems that let you animate

this already took way longer than it should've

[inner mulch]

r u creating emotes in minecraft?

[torn shuttle]

no

[inner mulch]

ok

[torn shuttle]

this is just to showcase FMM

[sullen marlin]

looks good, nice work

[torn shuttle]

well let's see how it looks in-game

[livid dagger]

Hi, I have a question. Is there any plugin for skyblock where can I make my own style of island and then people who just write /island create or something for creating, it would just make them the one I made?

[torn shuttle]

I think it's a bit too fast for it to cope lol

this is interesting, I wonder if there's a value leaking somewhere

[echo basalt]

https://tenor.com/view/bedwars-roblox-bedwars-merchant-marco-marco-gif-26534988

[lilac dagger]

yeah, it's a bit too fast

[torn shuttle]

it's weird too because it supposedly resets all the data every time

but it's clearly rounding something in here

[young knoll]

I kinda want to see what it would look like with mine

[lilac dagger]

and it looks 2d as well

the main body i mean

[torn shuttle]

it's an accurate recreation of the exact mc model, just adding a segment for the arms and another for the legs

not my fault mc is the flattest 3d game ever made

[lilac dagger]

true

[torn shuttle]

how weird

I need to figure this out

[young knoll]

He’s not looking so good

[remote swallow]

it looks like the arms are glitching on the out push

[civic sluice]

Is he ill and has lepra?

[young knoll]

I think he has more than that

[torn shuttle]

I think it might be the way it's supposed to loop the animation but it's kinda weird

the loop shouldn't be cumulative

[grave vale]

probably a stupid question but does anyone know how I can get NMS? I need to use the ServerLevel class but I don't seem to have it all

[worldly ingot]

ServerLevel is WorldServer

[grave vale]

is OpenInv's code outdated then?

they're using ServerLevel

[worldly ingot]

They're using Mojang mappings where you're not

WorldServer is CB mappings, ServerLevel is Mojmaps, but they're the same class

?mappings

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[worldly ingot]

I mean not quite what I was looking for, but a useful resource nonetheless lol

[grave vale]

oh I forgot to use them

I built them with buildtools but I haven't put them in all my projects yet

[remote swallow]

I think ur thinking of switchmappings

[grave vale]

works much better, thank you

[echo basalt]

Command isn't on plugin.yml

[deep herald]

oh im using extend command

[echo basalt]

go figure

Then you need to register it on the command map

[deep herald]

oh the tab completions?

[grave vale]

and now I seem to be missing ClientInformation in the same package, is it a class that was removed?

[grave vale]

I giggled really hard

[worldly ingot]

ClientInformation is the same between CB and Mojmaps so unsure why you would be unable to find it

[deep herald]

explain

[grave vale]

I've been having these odd problems all the time

[deep herald]

nms 😭

[echo basalt]

getPluginCommand returns null because the command isn't registered

If you have it on your plugin.yml you should use Plugin#getCommand

[deep herald]

how do i put it in the cmd map

[echo basalt]

If you want to register your own without putting it in the plugin.yml you gotta grab the CommandMap from the bukkit server and register stuff

[deep herald]

like this isnt a thing

[young knoll]

There are no exposed register methods

You need reflection

[echo basalt]

It's usually done in a pretty hacky way :)

reflection go brr

[deep herald]

chat

thats aids

[echo basalt]

(this is my own audience stuff)

[young knoll]

Wtf catch reflective operation exception

Kthx

[echo basalt]

lmao

[deep herald]

why is this aids to do

i just dont want tab completions on my cmd 😭

[grave vale]

I'm gonna try rebuilding spigot 1.20.1 with mojmaps

[young knoll]

You can remove tab completions with the normal command system?

Just return Collections.emptyList()

[grave vale]

oh my god I love the gui

[deep herald]

heh

[young knoll]

Wut

[sullen marlin]

Idk man, sounds too logical

[ember dew]

Is the 1.8.8 documentation currently down?

[worldly ingot]

We don't have 1.8 documentation

[lilac dagger]

about time

[deep herald]

1.8>>

[ember dew]

https://hub.spigotmc.org/nexus/service/local/repositories/snapshots/archive/org/spigotmc/spigot-api/1.8.8-R0.1-SNAPSHOT/spigot-api-1.8.8-R0.1-20160221.082514-43-javadoc.jar/!/overview-summary.html

[worldly ingot]

Oh, via Maven lol

[sullen marlin]

not even via maven

[worldly ingot]

Sorry, Nexus*

[sullen marlin]

via abusing nexus

[worldly ingot]

Yeah that's not how you're supposed to use Nexus

[sullen marlin]

the actual maven URLs still work

[worldly ingot]

If that url was ever browsable I'd be impressed

[ember dew]

¯_(ツ)_/¯

[sullen marlin]

I know the jar download was, I did not know you could get inside the jars

[worldly ingot]

That feels sketchy tbh

[sullen marlin]

https://hub.spigotmc.org/nexus/#browse/search/maven=attributes.maven2.groupId%3Dorg.spigotmc AND attributes.maven2.artifactId%3Dspigot-api AND assets.attributes.maven2.classifier%3Djavadoc

[ember dew]

What

So what was I using as a reference then

I'm so confused

[sullen marlin]

some url that google picked up that no one knew existed

which now doesnt exist

you should use maven https://www.spigotmc.org/wiki/spigot-maven/

[grave vale]

even after rebuilding it with buildtools, it isn't there

[sullen marlin]

failing that, download the javadoc jar you want I guess https://hub.spigotmc.org/nexus/repository/snapshots/org/spigotmc/spigot-api/1.8.8-R0.1-SNAPSHOT/spigot-api-1.8.8-R0.1-20160221.082514-43-javadoc.jar

[coral flower]

Hey guys, I'm still trying to spawn a Custom Zombie. I try it like that:

public class CustomZombie extends Zombie {
    public CustomZombie() {
        super(EntityType.ZOMBIE, ((CraftWorld)Bukkit.getWorld("roguelike")).getHandle());
        this.setPos(0,0,0);
    }
}

@Override
    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        CustomZombie zombie = new CustomZombie();
        return true;
    }

but I just get an error in minecraft: An internal error occurred while attempting to perform this command and the console doesnt give me any feedback. Any ideas how to tackle this?

[ember dew]

So then it'

it's been up for years

And and goes missing now

[sullen marlin]

yep, because nexus got upgraded

[echo basalt]

That message usually occurs when an error is thrown

I'm surprised the console has nothing

[ember dew]

That's really unfortunate timing I guess

[echo basalt]

you still have to add the entity to the world

(level().addFreshEntity(this))

[sullen marlin]

I guess

official javadocs are here

?jd

Spigot

[ember dew]

Yeah ik

Just wanted to be able to sort through everything available and not for 1.8

[coral flower]

hmmm okay I'll try this, thx! but so weird that my console is just empty tho

still nothing happens. Any Ideas how to fix this no error issue?

[valid burrow]

just empty

but you still get startup logs right?

[coral flower]

yuo

yup

[valid burrow]

huh

that is really weird

[coral flower]

like I also get sout logs

[valid burrow]

mh

well yh waht imllusion said was correct thouhg

about adding the entity to the world

[coral flower]

yea I tried that. But I think it doesnt work bc of the error I make somewhere else

[grave vale]

well it seems ClientInformation was added after 1.20.1 because I built and used 1.20.4 with mojang mappings and now it's there

[sullen marlin]

sounds about right

what are you trying to do anyway

[echo basalt]

yo md quick question given you're already here

what's the job of bungee's InitialHandler?

I need to port some stuff to velocity

[sullen marlin]

it handles logging in the player before they are joined to any servers

[echo basalt]

Is it bound to a specific protocol phase or does it do handshake, login and play?

[sullen marlin]

it wouldn't do play, but it probably does all the rest at some point

[echo basalt]

hm

[grave vale]

if you're talking to me, I'm trying to use OpenInv's method of loading an offline player to access data like their inventory

[silent tendon]

Hello, I would like to install the NMS for Spigot so that I can use it. I already have the spigot-1.20.1.jar file, but I don't know how I can use the whole thing in inellij. Can someone help me with that?

[grave vale]

if you built spigot with the buildtools then you already have it

also it depends on whether you're using gradle or maven to build your plugin

[silent tendon]

I use maven

[river oracle]

?nms

[undone axle]

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

[grave vale]

then what Gamernic sent is what you want

[river oracle]

what gamernic sent isn't even a good approach anymore

[deep herald]

why

[river oracle]

use Mojmaps obfuscated now adays is like shooting yourself in the foot for no good reason

[deep herald]

bro no way its the kid from cosmic reach again 💀

[grave vale]

oh yeah I didn't notice remapped-mojang wasn't there

[river oracle]

I have like 60,000 messages here why are you surprised

[deep herald]

fr

[river oracle]

read the blog post above

it walks you through everything

[grave vale]

I don't know how this translates to maven but you need to use the remapped-mojang

[deep herald]

imo, cosmicreach>>

[river oracle]

blogpost goes over it <3 thank god for mfnalex

[grave vale]

yup

[echo basalt]

I got 66k get rekt

[river oracle]

I do too

lol

you have like 100 more messages than me

[river oracle]

you've been around for less time than me nvm you joined the day of apparently :P I Joined late april

so consider me impressed

[coral flower]

okay even if I do and out of bounds error it doesnt show up in the logs:

int[] arr = {0, 0};
System.out.println(arr[-1]);
``` So it doesnt seem nms related. What else can I try?

[river oracle]

is the code even running

this doesn't provide much context that code 100% of the time will trigger an index out of bounds

[coral flower]

yea the code is running. Like when I change the onCommand like a sout it works.

What context do you need?

[echo basalt]

bro prob has a trycatch ignore

[dawn flower]

is there a sound for firework launch?

[coral flower]

where do I define something likethat?

To save ItemStack object in mysql db, Is serializing the best way?

[coral flower]

I already had a java course, but it didnt covered something like no errors gets printed out

[dawn flower]

?

[dawn flower]

system.out.println takes an object as a value, this might be COMPLETLY wrong but there's a slight chance arr[-1] is returning null and system.out.println prints nothing cuz null is well, null

it's supposed to throw an exception tho

[coral flower]

yea like in minecraft I get the an error. But it doesnt specify what error it is. Just that there is one

and the console is just empty

[dawn flower]

send the error

[coral flower]

In minecraft I just get An internal error occurred while attempting to perform this command what perfectly makes sense cause there is an out of bounds error. But the server isnt giving me any feedback. I assume there is a problem how I setup the server

[dawn flower]

in the console

check the console

[valid burrow]

@dawn flower are you not listening

he said theres no consle error

like 5 times now

[dawn flower]

that's weird

if it's in a try-catch then it wouldn't send that

[valid burrow]

mhm

[dawn flower]

try this

try {
  int[] arr = {0, 0};
  System.out.println(arr[-1]);
} catch (Exception ex) {
  ex.printStackTrace();
}```
if it doesn't print it then there's a problem with ur server

[coral flower]

okay there was some weird issue with the server and not with java. I did setup a new spigot server and now I'm getting errors again :) so back to my zombie problem. I try to spawn a custom Zombie:

@Override
    public boolean onCommand(CommandSender commandSender, Command command, String s, String[] strings) {
        CustomZombie zombie = new CustomZombie();
        return true;
    }

import net.minecraft.world.entity.EntityType;
import net.minecraft.world.entity.monster.Zombie;
import net.minecraft.world.level.Level;
import org.bukkit.Bukkit;
import org.bukkit.craftbukkit.v1_20_R3.CraftWorld;

public class CustomZombie extends Zombie {
    public CustomZombie() {
        super(EntityType.ZOMBIE, ((CraftWorld) Bukkit.getWorld("roguelike")).getHandle());
        Level level = ((CraftWorld) Bukkit.getWorld("roguelike")).getHandle();
        this.setPos(0, -57, 0);
        level.addFreshEntity(this);
    }
}

and I get an java.lang.ClassNotFoundException: net.minecraft.world.entity.monster.Zombie am I using the wrong Zombie class?

[sullen marlin]

did you remap your plugin

[coral flower]

yea I think so. I run buildtools and extended my pom.xml like in this tutorial: https://blog.jeff-media.com/nms-use-mojang-mappings-for-your-spigot-plugins/

[livid dagger]

Hi, I have a question. Is there any plugin for skyblock where can I make my own style of island and then people who just write /island create or something for creating, it would just make them the one I made?

[silent tendon]

Thank you, it works

[river oracle]

You need to use the maven to compile not intellij

You can't build artifacts you must mvn package

Or whatever

[gleaming grove]

Question, how can I dynamically register commands in Spigot> Currently I'm using this hacky way, hovever it only works inside onEnable method. When server is running commands are not longer registered properly (I can not see them in minecraft)

public class CommandCreator {

    public static void Create(String name) {
        FluentLogger.LOGGER.info("Creating command,", name);
        registerBukkitCommand(new TestCommandClass(name));
        FluentLogger.LOGGER.info("cmd created", name);
    }

    private static boolean registerBukkitCommand(TestCommandClass simpleCommand) {
        try {
            var commandMap = (SimpleCommandMap) ObjectUtility.getPrivateField(Bukkit.getServer(), "commandMap");
            return simpleCommand.register(commandMap);
        } catch (Exception e) {
            FluentLogger.LOGGER.error("Unable to register command " + simpleCommand.getName(), e);
            return false;
        }
    }

    public static class TestCommandClass extends Command {

        protected TestCommandClass(@NotNull String name) {
            super(name);
        }

        @Override
        public boolean execute(@NotNull CommandSender sender, @NotNull String commandLabel, @NotNull String[] args) {

            FluentLogger.LOGGER.info("Siema tutaj commenda " + this.getName());
            return false;
        }
    }

}

[echo basalt]

If you register commands after the server's enabling you need to resync them

There's a method for that

[gleaming grove]

provided by API, or I need to use reflections?

[echo basalt]

Reflections, of course

syncCommands is the method you're looking for

No params

[silent tendon]

If you use the exe, activate this under Options in BuildTools:
This is how it worked for me

[gleaming grove]

inside what type?

[echo basalt]

SimpleCommandMap

[coral flower]

I updated the pom and then used maven compile

[coral flower]

yea I checked that one

[gleaming grove]

hmm what version of spigot are you using? I can not see it at 1.19.4

[echo basalt]

Hm, might be new

or paper-specific, go figure

In that case for existing players there's a method to resend commands

the command api is icky as hell

[gleaming grove]

okey, thanks for help

[dawn flower]

can u hide a player WITHOUT invisibility for a specific player without hiding him from the tablist

[waxen plinth]

you need reflection

https://github.com/boxbeam/Ordinate/blob/master/platforms/spigot/src/redempt/ordinate/spigot/SpigotCommandRegistrar.java

[coral flower]

I'm still trying to figure out what is wrong with my project that I get the class not found error. Maybe there is something wrong with my pom.xml, maybe someone can have a look at it: https://pastebin.com/Yy15LKqq

[sullen marlin]

<outputFile>C:\Users\user\OneDrive\Desktop\PluginTestServer\plugins\RoguelikeSpigot.jar
</outputFile>

its your shade config

delete that

[coral flower]

just that line? and how do I export my jar then?

[sullen marlin]

copy it from the target folder

[coral flower]

oh that worked,thx!

[gleaming grove]

ok the syncCommands method is not inside SimpleCommandMap but CraftServer , anyway thanks for help it works 😄

[grim hound]

I'm writing a map data packet like this

but the client disconnects on 1.16.5 with "ArrayIndexOutOfBounds"

on wiki.vg I found this to be the only difference in protocol on 1.19 and 1.19.2

https://wiki.vg/index.php?title=Protocol&oldid=17753#Map_Data 1.19 and below

https://wiki.vg/index.php?title=Protocol&oldid=18067#Map_Data 1.19.2+

so it shouldn't change

and it works on 1.20.1

[lilac dagger]

consider looking in the nms as well

[grim hound]

I did

it just writes false

this is 1.19.2+ /\

this is 1.19 and below

hmm I guess there is a difference

[lilac dagger]

i'm pretty sure you forgot something somewhere

these things are finicky

[grim hound]

yeah, here

[lilac dagger]

as far as i know minecraft uses special byte manipulation in some areas

[grim hound]

the array is not optional here

[lilac dagger]

what about ?

you might wanna look what mojang does different to this

mojang has a friendly byte buffer that extends what you're using

[grim hound]

ye

[grim hound]

netty-provided bytebufs are just as fine to use

also, I can't even use the FriendlyByteBuf class

👍

[lilac dagger]

i know, but it does something different when it extends

so you might wanna make sure it matches
