[young knoll]

You probably have to set the children first

But I have no idea

[tight compass]

😮‍💨

[primal island]

Anyone who can help me 🙂

[wet breach]

why would you use skript if you can use java?

[primal island]

For like scoreboard or something, just so i can easy get it. But do you think it's easier just to make a scoreboard in a plugin and take the placeholders in that?

[young knoll]

Just use an existing scoreboard plugin

[primal island]

True, but still know how to use it in script it just says it can't understand the expression...

[earnest girder]

If I have a custom item that launches a projectile (snowball) and it hits a player and I detect it and damage the player, how can I make it so that the shooter of the projectile is equal to PlayerDeathEvent#getEntity#getKiller if the player dies from the damage I give them?

In other words, how can I know the killer of a player if it is from a custom projectile and custom damage?

Is it possible to assign a killer in ProjectileHitEvent?

[vital ridge]

I'm having a problem with placeholders. I'm creating my custom placeholder with PlaceholderAPI (extending the PlaceholderExpansion class).

Heres my code:
https://paste.md-5.net/zanenakayu.java
Here is the code of me registering it in the main class:
https://paste.md-5.net/mawirituda.cpp

Ingame when i run /papi list, "glarkourparkour" shows up.

But whenever I try using the actual placeholder with commands like:

/say The best food is %glarkourparkour_featured_course_author%

It doesn't work. I even have a debug message under #onRequest(), but this does not print out aswell.

[young knoll]

DamageSource (specifically the builder) to construct a damage source that has the player as the causing entity

[earnest girder]

I figured out that I can send in a damage source entity when damaging the player

[primal island]

Do you mby know how to use it in skript? Or are you also trying to fix so it works in general?

[vital ridge]

I don't know how to use it in skript, I'm just trying to create a custom placeholder that works ingame.

[primal island]

Ooh, okay. Don't know if you can do it in that way tho

You can use /papi parse me %glarkourparkour_featured_course_author%

Then see what the output is

[vital ridge]

whats un1bande?

[primal island]

Ooh sry didn't remove it mb

[vital ridge]

/papi parse me %glarkourparkour_featured_course_author%
THis didnt work

just printed out unparsed placeholder

[primal island]

But it's a plugin i work on. It's like gangs, it's "bande" in danish. It's something that many danish prison servers has.

[primal island]

Okay, idk then 😦

[vital ridge]

MAIN.getLogger().info("Requested placeholder: " + params);

Is what I'm using under onRequest() function

And this does not run.

So yeah something is fked up

Idk what doe

[primal island]

I have tried the last 3 hours i think to get my placeholders to work in skript. But don't know how 😦

[golden turret]

any ideas on how to fix this? I can get the file manually without problems, but gradle at github actions is giving this

[vital ridge]

Okay wtf, I started using onPlaceholderRequest() and it works now
So why tf didnt onRequest() work...

[primal island]

Could it be the reason why my placeholders dosen't work in skript you think?

[sullen marlin]

Guess he's blocked GitHub

[vital ridge]

Idk, I watched kangarkoo video, he used onRequest() and it worked for him, the API also specified that I can override either onRequest() or onPlaceholderRequest()

I'm too lazy to break my code again but probably onRequest() runs if a console tries to access the placeholder or sht like that.

[primal island]

Mine just give me error at @Override

@Override
    public String onPlaceholderRequest(OfflinePlayer player, @NotNull String identifier) {
        if (player == null || player.getUniqueId() == null) {
            return "N/A";
        }

I have more than that tho.

[vital ridge]

Show me your code

That's everything `

[vital ridge]

Ur having an error because you are overriding the method with wrong parameters

Change OfflinePlayer to Player

[primal island]

Ooh mb haha

I'm tired, it's 2am man

[vital ridge]

3AM for me

[primal island]

Damn

[primal island]

Okay, so dumb question, but how do i turn on UTF-8 if that's possible in Intellij Idea. Can't use the danish letters "Æ, Ø & Å"...

[rough ibex]

It should be default

whats wrong

[primal island]

Just my letters that's looks weird cause i use some of the danish letters.
It should say "Indsæt Penge" "Tryk for at tilføje penge til Bande Banken"

In English:
"Deposit Money" "Click to deposit money to the Gang Bank"

Mby it's because i use a config.yml to set it...

It could be the error i think

But i'm pretty tired so i think i will fix it later. Good bye

[golden turret]

you should set utf-8 on whatever build tool you are using

[primal island]

I guess i could just make a encoder or something in the plugin, that goes in the config when it's used and then edit the letters. Could be a idea i think. Could try and see if it's possible.

Don't know if it's called encoder but my english is pretty bad..

[primal island]

I can try and look on it before i go too bed. But goodnight man

It's already set to UTF-8, think it's because it's from the config.yml...

[golden turret]

https://google.com/search?q=how+to+use+utf8+on+maven
https://google.com/search?q=how+to+use+utf8+on+gradle

[primal island]

It's set to UTF-8 everywhere so i think it's because config.yml is stupid aha

But thanks tho

[golden turret]

could you show us your pom.xml or build.gradle please

[primal island]

The whole file?

[golden turret]

yes

[dawn flower]

how do i return a variable in a Supplier?

i don't want the value of the variable when the supplier was made, i want the current value

int value = 1;
Supplier<Integer> supplier = () -> value;
value = 2; // supplier will now return 2```

[rough ibex]

supplier.get()

[worldly ice]

AtomicInteger, class field, do logic inside supplier instead of outside

honestly sounds like a bit of an

?xy

[undone axle]

https://xyproblem.info/

[dawn flower]

i got a loop section that basically just executes abunch of actions x amount of times, these actions could want to access some values like what iteration we're currently in and to do that i use suppliers which would always return 1 until i used AtomicInteger

it might seem like just more steps to make a for/while loop but it's just a simplified explanation

[worldly ice]

could you not have a local variable that stores the number of iterations (or whatever else you need) and just access that whenever needed?

[dawn flower]

it's an abstract class of loopsection that other sections extend like for loop and while loop, for loop would also want to register some loop values like the current object being iterated

[worldly ice]

not sure what loopsection is but i assume it's something along the lines of

public abstract class LoopSection {
  public abstract boolean tick();
}

? because in that case using an atomic int wont even be needed

like so a for loop implementation could have a constructor that takes in a consumer<T> and an iterator or something and pass in the current object being iterated into that consumer every tick

[dawn flower]

public abstract class LoopSection extends Section {
  public void executeSection() {
    // executes the section's body, in this case calling executeIteration unless shouldExit() returns true
  }

  public void exitSection() {
    // called after the section is executed to then continue execution of the parent section, in this case do executeIteration is shouldExit() is false
  }

  public Object getLoopValue(String name) {
    // returns loop value
  }

  public abstract void executeIteration();
  public abstract boolean shouldExit();

  protected void registerLoopValue(String name, Supplier<Object> supplier) {
      // register loop value
  }
}

is a minified version that explains how it works

[worldly ice]

ah so the supplier in #registerLoopValue is the supplier you need the atomic int for?

[dawn flower]

yep

it has a constructor that registers an "iteration" loop-value with supplier () -> iterations.get()

[worldly ice]

im wondering if you could just return the current loop value in #executeIteration and storing that where needed rather than having a separate method and supplier for it

im assuming the loop value is just the current "value" the loop is on

[dawn flower]

loop value is the current value that a for loop would be in rn and it could be the amount of iterations already done, depending on the given name

there's multiple loop values

[worldly ice]

oh right yeah i didnt see that

even then you could have like a record that contains data about the loop value

then executeIteration would return that record

you could add a generic too like

public abstract class LoopSection<T> extends Section {
  // ...
  public abstract T executeIteration();
  // ...
}

and a for loop implementation could have the T set as

public record ForLoopValues<T>(int iteration, T value)

forgor syntax of records i think that's right

[dawn flower]

the thing is the section's body has no idea what the executeIteration returns since technically executeIteration is the one that executes the body

it's possible but it'd just add complications

[worldly ice]

does the section need to know what executeIteration returns? you could make an interface depending on what the section expects from the return value of executeIteration. because currently, are you just inputting magic strings and checking null in section?

[dawn flower]

it's currently like this:
root section -> multiple actions and inner sections
inner section -> multiple action and more inner sections

action knows what section it's currently in so if it wants to know what iteration it is in it could first check if it's in a LoopSection then cast the section it's in to a LoopSection and then do LoopSection#getLoopValue("iteration")

[worldly ice]

if it's expected to always have an iteration property, you could just make an interface with like a #getIteration method

if not you could cast the return type ig

and do something different depending on what it returns

[dawn flower]

you mean make a getIteration method in LoopSection?

[worldly ice]

i mean having executeIteration return like a T extends LoopValue

where LoopValue is an interface that contains a getIteration method

so whenever you execute on that section you get its current loop value

and other properties depending on the implementation

[dawn flower]

i could try doing that

Does anybody know since they added string for CustomModelData, how i would use that when the method is forced to integers?

[acoustic shuttle]

Use NBT Api

[worldly ice]

use PDC instead since you're using 1.14+

[worldly ice]

?xy potentially? if its for a resource pack just change the tag to use integers instead of strings

[undone axle]

https://xyproblem.info/

[inland agate]

I get your point, but i rather dig into the option of using strings, since this is a new feature and will make many of the upcoming tasks a lot easier. Thats why i wanna find out how i use string for the metadata.

[worldly ice]

use PDC then it probably better suites your use-case

I am attempting to make it so packets for only certain chunks are sent to the client, giving the effect that only certain parts of the world have loaded (on client side)

i tried tinkering with protocollib but failed miserably, anyone got ideas?

[smoky oak]

any obvious issues with this? its some string manip https://paste.md-5.net/ikadirusav.cs

[upper hazel]

i need someone in my team who know how work with byte code

i need use it for remove reflection 🙂

[pseudo hazel]

wtf does that even mean

that sounds cursed

[upper hazel]

sec i translate for more information

for those who don't know, I'm doing a project. Combining Spring with Bukkt api. In short Spring is a framework that provides convenient mechanisms for developing backend sites. DI, JPA, Controllers and all this is based on anotations for convenience. And to leverage all this Spring uses byteCode generation instead of reflection to optimize searches

i trying create DI too

so i want find someone who know how work with bytecode and help me with it

[blazing ocean]

and why do you need it to "remove reflection"

[eternal oxide]

byte code manipulation is more difficult than reflection

[blazing ocean]

spring just uses cglib

[upper hazel]

optimize code

reflection is long

[blazing ocean]

And writing bytecode won't help with that

[upper hazel]

i will have many annotations

[blazing ocean]

you still cannot access private methods with bytecode

[upper hazel]

oh sorry i mean ASM

[blazing ocean]

Okay?

ASM is just a bytecode lib

[upper hazel]

yes and this help with remove reflection code where is possable

[eternal oxide]

I did a LOT of work with IDA and ASM modding NeverWinter Nights. Avoid it if at all possible

[blazing ocean]

No it won't

Where do you think that will remove reflection?

[upper hazel]

reading class?

create proxy i gess

[blazing ocean]

Proxying is still some reflection iirc

Yeap

[upper hazel]

you sure?

[blazing ocean]

https://github.com/adoptium/jdk/blob/master/src/java.base/share/classes/java/lang/reflect/Proxy.java

java.lang.reflect

[upper hazel]

i think this not mean you cant create proxy class with ASM

i was hear this better then reflection

[blazing ocean]

???

ASM is just a bytecode lib

You need reflection in some places and using ASM will not help you

Unless you really wanna transform the base JDK's classes at runtime

[shadow night]

Are you even able to properly do that

Something tells me no

[blazing ocean]

Mixins can

[shadow night]

Mixins cannot afaik

[upper hazel]

yes reflection need but the less the better.

Spring framework based in MANY annotation

just image what will be if you will use only reflection

[blazing ocean]

I believe I have mixin'd into String before

[blazing ocean]

I think you just have zero clue what bytecode injection even is

[shadow night]

Are you sure

[blazing ocean]

not entirely

[shadow night]

Last time I asked in fabricmc they told me no

[blazing ocean]

https://git.frohnmeyer-wds.de/JfMods/QuickMath/src/branch/master/src/main/java/io/gitlab/jfronny/quickmath/BytecodeTransformer.java

Ah yeah you can't do mixins but ASM directly

[upper hazel]

Like I said I'm not very good at using byte code to create and read classes so I want to find someone who is good at it. Only what i know use byte code this better then reflection

end i need it

[blazing ocean]

Using bytecode is not better than reflection

[upper hazel]

why spring use it then

[blazing ocean]

How would I know

Ask spring

[upper hazel]

and why is not better

[blazing ocean]

Because it does not allow you to do more than reflection

if you are not overwriting existing classes

And the only way to get annotations of something is reflection lmao

You could write bytecode to call the reflection but it's just pointless

sir this is help-dev

[rough drift]

rad I'm stupid

[blazing ocean]

I know

[upper hazel]

so you mean i not can create class ? And reading class with reflection is faster then byte code?

lets say ASM

ASM not faster reflection ?

[blazing ocean]

You can create classes but can only load them in another classloader iirc

But what the fuck do you even mean reading a class

[upper hazel]

readig class

[eternal oxide]

are you trying to actually create new classes on teh fly and not just instances of existing ones?

[upper hazel]

proxy classes

and connection

read all annotations, methods, constructor

[blazing ocean]

That does not explain anything

And reflection also isn't slow at all as long as you cache it

[upper hazel]

ASM allow you read class like file if i remember

[blazing ocean]

It makes zero sense to parse and read a class file that's already loaded at runtime

[shadow night]

Ye lol

[eternal oxide]

yeah I don't see any point in what you are doing

[upper hazel]

so this mean you think reflection is faster

[eternal oxide]

why is speed an issue here?

[blazing ocean]

premature optimisation

[upper hazel]

you say me or him?

[blazing ocean]

I was replying to elgar

[eternal oxide]

creating Proxies at runtime is not going to have a speed issue using ASM or reflection

pick whatever is simplest to do

[blazing ocean]

Reflection isn't slow as long as you cache it

[upper hazel]

hm

[eternal oxide]

I'm only guessing but I have an idea hes trying to inject new classes from file or even through db queries

basically tryign to script runtime actions

[blazing ocean]

me when I store a classfile in postgres

[eternal oxide]

yep 🙂

[rough drift]

method handles are faster than directly invoking a method sometimes, too

[wet breach]

if you are making your own implementation of the server, you don't need reflection or annotations as you could just modify the code as you see fit. If you instead mean to say you are creating a plugin and need to make methods that are private or whatever accessible annotations is not going to fix this. Annotations is a processing mechanism that either happens at compile time or at runtime which neither of which will change how the server code runs because annotations doesn't bypass the JVM mechanisms which is what reflection does. If this plugin is not going to be released for the public and instead just your private server then once again you could just modify the server code directly that you are needing access to without all this complex unnecessary stuff. Proxying classes is a method that can be used but its not more optimal then reflection nor is it inferior as it depends on the scenario. With spigot most times reflection is going to be the best

[upper hazel]

alr

thenks

[misty ingot]

when i remove BELL using EditSession#removeBlocks in a selection, only one of these bells gets removed
using FAWE

i would ask in the FAWE discord but their support is basically dead

es.replaceBlocks(select, new BlockMask(es.getExtent(), new BaseBlock(BlockTypes.parse(material.toString()).getDefaultState())), BlockTypes.AIR);
the material is BELL

[blazing ocean]

still ask

[misty ingot]

i have asked

never got a reply

[blazing ocean]

it's because you're replacing the default state

which also contains the rotation

[misty ingot]

how would i replace every state then

[blazing ocean]

BlockType is a mask or whatever it was called

nvm, use a SingleBlockTypeMask

session.replaceBlocks(region, SingleBlockTypeMask(session, BlockTypes.BEDROCK), BlockTypes.AIR)

[misty ingot]

it works

wonderful thanks

[smoky oak]

how often do you need to access a array[index] before it's worthwhile to put it into a temporary variable?

[rough drift]

depends, as long as you stay under 4 local variables they have the fastest access

[smoky oak]

can you elaborate on the why for that?

and no i def aint below 4 lol

your code makes it required.

so...???

don't code it like that then

[sly flint]

"This plugin is required"

for this

?

[sterile axle]

💀

yes...?

[sly flint]

the video show it

no

no

its github

[blazing ocean]

I'm so confused

[sly flint]

?

[rough drift]

the JVM has 5 specialized instructions for the first 5 locals iirc (or was it 4?) one is always occupied by this, and thus

[sly flint]

@blazing ocean

[chrome beacon]

Why did you ping him

[sterile axle]

bc it's fun

@blazing ocean

[slender elbow]

that is not going to make a performance difference...

[blazing ocean]

@sterile axle

[sly flint]

hmmmmm

[chrome beacon]

Pings rad again 💀

[sly flint]

@blazing ocean

NO

[blazing ocean]

no you're not

[sly flint]

What is going on

[smoky oak]

Caused by: java.util.regex.PatternSyntaxException: Dangling meta character '?' near index 0
?

can you not split by "?" or something?

[chrome beacon]

Escape it

[blazing ocean]

invalid regex

[smoky oak]

ah yes of course bleh

regex in a nutshell

the problem i have is that this is a string input

how do i tell regex 'hey split by this string'

[chrome beacon]

Escape the ?

[slender elbow]

Pattern.quote(String)

[blazing ocean]

String#replace(CharSequence, CharSequence) doesn't do regex does it

[smoky oak]

i have the split string as variable input. sure, i can escape the questionmark where i call it, but thats kinda not the point

hm, delmimter("", split) maybe?

no thats an int

[slender elbow]

zzz

[smoky oak]

ah

im blind

ty

hey new error!

[sterile axle]

pretty sure this dude barely knows java, or quite possibly barely knows his way around a computer

this is pretty pointless

[slender elbow]

are you sure? they have "JAVA" in their name tho

[chrome beacon]

In my experience in this chat the more people advertise their java skill in bio (and now name) the worse they are at Java

Having Java dev in bio is big red flag that they do not know Java

[slender elbow]

JAVA PROFESSIONAL (started this weekend)

[sterile axle]

meh it's usually just kids who watched some videos and wanna make stuff, which is fine. but it's like, meet me half way. the stuff like "not working", "theres an error", upload random text and ask for help bs gets tiring after well over a decade (for me) at this point of seeing it

[inner mulch]

haha true

[sterile axle]

like, ask a full question, show your entire code, what did you try, do you have any ideas about what the issue might be...what can you contribute to this discussion? i am not google. or better, in 2025, i am not chatgpt.

if you can't bother to meet me half way to the finish line, then i am not going to entertain you, gud nayt

[slender elbow]

so what you're saying is one is better off asking chatgpt than you

runs

[chrome beacon]

💀

[sterile axle]

yes

actually, unironically, ask chatgpt before you ask me plz

[misty ingot]

is that allowed here

i think theres a forum for that

[chrome beacon]

This smells like scam

[smoky oak]

its a request, not a requirement i guess? in the rules

[misty ingot]

it does

[smoky oak]

hes asking for your country of residence and his answer to asking why he wants to know is 'i dont have time for this' lol

[orchid furnace]

How can I send all arguments because I did a silly and accidentally only made the command send back the first argument

using args[0]

[smoky oak]

can't you just concatenate them?

[sly flint]

help

[smoky anchor]

You've already been helped.
Stop being annoying before the whole server blocks you.

[sly flint]

no one helped me

[sly flint]

this is help?

[pseudo hazel]

yes

you still havent explained what the actual issue is

[nova notch]

legendary message

[smoky anchor]

Please don't tag random ppl when.

You can reply without the tag.

[nova notch]

I'm sorry if this guy is just using a translator or something but "ther is a proplem" is so funny

[pseudo hazel]

no translator is that bad

[pliant topaz]

Yes

You are using the PlaceholderAPI

so it is required for you to run code from it

Your plugin only softdepends on it, which doesnt make sure PlaceHolderAPI is loaded before your plugin, so if your plugin loads first it cant find the code from the API making it error

If you don't want it as an dependency, don't use it

[sly flint]

it`s depend

and i run it on the server but it's the same

[smoky oak]

is this the x coordinate of the chunk corner, or the actual chunk coordinate? I can't tell

[slender elbow]

chunk coordinate

[smoky oak]

k

[pseudo hazel]

the actual position can be calulated easily

[smoky oak]

nah im asking coz i need mediumint

having actual coords would need to be shifted to fit

on a different topic, why does this error appear? the previous code cannot not return something

(its a switch on a enum with all branches filled, all returning something)

[slender elbow]

return the switch expression

[smoky oak]

im doing my returns in the switch

guess i do yield now

[slender elbow]

return switch(foo) {
  case Foo.FOO -> 123;
  case Foo.BAR -> 456;
  case Foo.BAZ -> {
    yield 789;
  }
};

[smoky oak]

what

[slender elbow]

i mean, i can't see your code

[smoky oak]

no like

?????

wym this aint a switch bruh

is it the lambda thing?

[slender elbow]

more code

i ain't a psychic

[smoky oak]

why would seeing the full switch statement help here? its complaining that it's 'outside a switch expressions' which i doub is affected by the other cases
genuinely curious lol

[slender elbow]

i need to see the code to know what intellij is seeing to see how you can fix it

[river oracle]

You're annoying just fork it over context almost always helps

[slender elbow]

otherwise i literally cannot help

[smoky oak]

ah thats fair enough

?paste

[undone axle]

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

[smoky oak]

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

[river oracle]

It's because you're yielding instead of returning

[slender elbow]

well, it's not exactly a switch expression, that's the thing

yield can only be used in a switch expression

[smoky oak]

the lambda, then

wait

[slender elbow]

like this, returning the switch expression; once the code is adjusted as such it'll be fine

[smoky oak]

what the fuc
that error is misleading as hell

[river oracle]

Not really you just mixed yield and return and never return from the function

[slender elbow]

eh, it's not wrong

[smoky oak]

i read that as 'switch is not switch'

[slender elbow]

switch expression

[smoky oak]

yeeeeah

aware now

[primal island]

Hi! Is it possible to make a encoder or something like that, that checks the config.yml when in use and then change som letters so UTF-8 works on them? Cause i'm from Denmark so i use some danish letters that won't work in the config when i use them ingame from the config? Hope you understand my english aha

[chrome beacon]

Save the file in UTF8 with your text editor

[primal island]

The thing is that in the config the letters is right but ingame it's not...

[chrome beacon]

Did you save it with UTF8

[primal island]

Yep, it's all saved in UTF-8

[chrome beacon]

Try starting the server with the -Dfile.encoding=UTF-8 flag

[smoky oak]

ok this is cursed
case STRING -> object instanceof String string ? string : null;

[blazing ocean]

JS ahh

[primal island]

In the start.bat right? I'm using localhost to test on

[chrome beacon]

yes

[primal island]

Alr will try that

Like this?

@echo off
java -Xmx1G -Xms1G -jar server.jar nogui
-Dfile.encoding=UTF-8
pause

[blazing ocean]

No, java -Xmx1G -Xms1G -Dfile.encoding=UTF-8 ...

[primal island]

Oooh

Ahaha

Thx that worked

[chrome beacon]

Thankfully Java 18 and above always uses utf8 by default so that environment dependent issue doesn't happen

[primal island]

But why not java 8? I'm just trying to make a plugin for 1.8.8, but then UTF-8 isn't set for configs and that 😦

[blazing ocean]

Because ancient

[eternal oxide]

If your original config is created as UTF8 it will be saved/loaded as UTF8

[digital basin]

Hello! I am very new to spigot and I've been searching through the discord but couldn't find any great examples. Could you in theory register a custom block natively in spigot and then have a client using a mod fill in the gaps?

Looking for an example for registering the block on spigot specifically!

[eternal oxide]

No

Your mod would do it, or you use a platform which supports both Spigot and mods

[fathom island]

Hey, since 1.21.2 you can no longer define the effects in a FoodComponent, how should you do it now? I can’t find anything similar to a ConsumeComponent

[chrome beacon]

ConsumeComponent is missing from the api

[eternal oxide]

The platform injects custom blocks into Bukkits Materials

[chrome beacon]

Need to use nms

or make a PR 🙏

i am going to bring forth exactly one pr

[eternal oxide]

I did a pr once. It was rejected 😦

[smoky oak]

i want to swap the call order for two events in the player logout lol

[digital basin]

Hmm, not sure if this will help but I am trying to create a system that allows Chunker to read the custom blocks on Java. I can't seem to get Fabric to do it so I was hoping another plugin loader would. Thanks for the insight though, perhaps this approach isn't the right one.

[eternal oxide]

It was to Bungee not Spigot though

[eternal night]

Happens to the best PRs

[worldly ingot]

PR exists already

[eternal oxide]

I only wanted to expose teh Map behind the Config

[worldly ingot]

Is just stuck in serialization hell

[smoky oak]

oh hi choco, have you seen my question the other day?
ive been told u know about spigot internals

[chrome beacon]

ouch

[primal island]

Everything is right in my config and checked if it's UTF-8 and it is, it's just when i use it in a GUI ingame it isn't but it's fixed now

[chrome beacon]

What's the problem exactly?

(can't see PRs without account)

[eternal oxide]

It it an actual yml config you are using? If it is you may be suffering from teh system code page. I see its fixed for you though

[worldly ingot]

I think Doc updated it a few days ago so it just needs another review

[primal island]

I'm using a file i called config.yml. But someone gave me a line to type in my start.bat, so it's fixed now..

[misty ingot]

is there a way to create a sort of invisible wall that projectiles can pass through but players cannot?

[mortal hare]

my new rule of wisdom: never abstract away method parameters using default value overloads

foo(bar a) {}
foo() { foo(defaultA); }

this might work for simple case like this, but after a while you will get combinatorial explosion of function parameters that need to be default

instead be more verbose and just have pass the default value through parameter itself

foo(Bar.DEFAULT)

or smth

[worldly ingot]

You do that only when the default behaviour is obvious and documented. There's a reason we have Javadocs

[mortal hare]

tbh those overloads are kinda evil because it might make your code cleaner but then you're gonna scratch your head of how to decouple the code

[mortal hare]

i would rather not even provide such thing even if it was documented

it just that such methods succeptible to deprecations in the future

[worldly ingot]

All methods are susceptible to deprecation

[smoky oak]

.equals aint

[mortal hare]

again kotlin moment

kotlin allows to pass default values however you want

by using parameter names lol 😄

[eternal night]

Still pretty ass

That doesn't fix ABI

[mortal hare]

fair enough,

[misty ingot]

man i want optional arguments to be a thing in java
i dont want to learn kotlin just for one thing

[mortal hare]

kotlin is just a hack on top of JVM

mostly everything you can write in Kotlin, you can do it java

albeit in such a nasty way

[blazing ocean]

Kotlin is also a multiplatform language

[mortal hare]

Gradle supports C++

but i've never seen anyone use C++ with gradle

[blazing ocean]

Gradle also supports x86 assembly

[mortal hare]

and ARM

[blazing ocean]

Right, there's a huge community for kotlin multiplatform

KMP is amazing for app dev

There's even https://klibs.io/

[misty ingot]

ion wanna have to learn another language just for optional arguments in methods
i think ill stick to java

[blazing ocean]

You know, Kotlin has lots of other features too!

[misty ingot]

none of which i will ever use!

[blazing ocean]

Doubt that

[misty ingot]

only times ive really learnt a new language is if it enables me to start doing something new

or if its far better than what i already use

[blazing ocean]

Does your java have kotlin's amazing null safety and chaining

[misty ingot]

no but we can type

[blazing ocean]

Right but a lot of people don't use optionals

i.e. spigot

Spigot doesn't use optionals so you're gonna just end up with a trillion not null checks and shit

[misty ingot]

for custom methods

[blazing ocean]

whereas with Kotlin you have actual nullable types

[misty ingot]

just write your code properly

[blazing ocean]

?

[misty ingot]

nvm im cooked

disregard that sentence it made no sense

ive been IntelliJ-ing too much

[orchid kernel]

does anyone know how I can make a mob drop xp if it wasn't killed by a player?

[valid burrow]

someone explain this to me

[blazing ocean]

are you sure you are using the latest jar

[orchid kernel]

I've gone through the documentation and I'm assuming entityDeathEvent is the right place to be messing with, but i can't find any method that would let me decide whether the mob drops xp or not

[valid burrow]

yes

i even changed the name of the class just to be sure

[blazing ocean]

look at recaf

[valid burrow]

its there most definetly

[rough ibex]

Correct package name?

[valid burrow]

yep

intellij doesnt complain either

[blazing ocean]

do you have it loaded twice

[valid burrow]

it only happens when i actually run it

😭

nope

[orchid kernel]

?

I'm wasting my time aren't I.

[smoky oak]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/entity/EntityDeathEvent.html check and change the drops of this i guess

[flint coyote]

Is there a way to get the "best" possible drop of a block?
I want to remove a block by code but I still want whatever block that is to drop the "best" possible default drop. E.g. stone instead of cobblestone or ice instead of nothing.
Blocks that don't drop anything (e.g. reinforced_deepslate) should not drop anything as well.

[bronze robin]

can I get some help developing my Minecraft server it runs on purpur and I’m pretty sure that runs spigot stuff

[flint coyote]

Not sure if there are blocks where a silk touch pick won't be able to yield something, otherwise I can just use that by default

[chrome beacon]

?fork

[undone axle]

SpigotMC maintains the Spigot server. If you are using a fork of Spigot (such as Paper, Airplane, Purpur, or other derivative works), you should seek support in the appropriate Discord servers.

[smoky oak]

actually

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Block.html#getDrops(org.bukkit.inventory.ItemStack)

• silk touch pick

should do it

[flint coyote]

Alright lets hope it will stay like that and they won't decide that Grass blocks need silk touch shovels specifically, thanks

[smoky oak]

it doesnt

[flint coyote]

I wasn't sure if there's any material where it is like that. So for now I'll just pray they don't change it

[smoky oak]

reason i said pick is bc 90% of the time im holding it and when i randomly mine a grass block its still grass

i know silk touch on picks works on more or less anything affected by silk touch

[torn shuttle]

someone on the internet just accused me of being old because I played civ 3 on release

if you have that kind of power go after the people that actually should bleed money lol

You're just old

alright one sec let me leave smth

[misty ingot]

.

[smoky oak]

project blocks to the player AND move them back if they move into it

[rough ibex]

how do people end up being in 100 servers

you cannot possibly need to know 100 sources of information like that

[wet breach]

about half of them are for the emoji's/stickers/gifs

the other half is for informational purposes for variety of stuff

for example, I am in paper but I don't actively engage in that discord

mainly because they would probably ban me if I did 😛

[misty ingot]

well the wall has to be invisible

[smoky oak]

🚫

[misty ingot]

players from either side shouldnt be able to move to the other

so push the player back is the plan then

with a barrier block wall

[echo basalt]

I think I'm in 50 servers max

and I can prolly leave half of them without even noticing

[bronze laurel]

How do you do teams but with packets?

And ProticolLib

[blazing ocean]

there is no reason to do scoreboard-related things without using the API

[bronze laurel]

I want prefixes that are automatically done

And tab sorting

with luckperms

so if I ever add ranks nothing happens

[chrome beacon]

So why can't you do that with the api

[bronze laurel]

What API and how?

I can't find much information on it.

[bronze laurel]

The Spigot API?

[chrome beacon]

yes

First thing that pops up lol

[fast jasper]

hello. I am making a minigame Spigot plugin. in my Spigot plugin I'm trying to show a player's name in chat. however, it does not display the way I would like. I've tried player."getName()", "getDisplayName()", and "getListName()". all of these are returning the same value for me. they are returning a plain white text only version of the player's name. however that is not what I would like. I would like the version of the player name that shows up on the tab list, and in chat, such as with death messages and such. in my minigame, there are multiple teams, each with their own color and prefixes. when a player is shown on the tab list, or the scoreboard sidebar, or the chat in a death message, their username has their color, and their team prefix automatically shown by Vanilla Minecraft. I would like to "get" this string, but I cannot seem to find a method that returns this version. does anyone know what method to use to get that built in vanilla formatting instead of the plain version?

[young knoll]

I don’t think there is a method for that

[fast jasper]

really? huh, I'm surprised there doesn't exist a way to obtain this vanilla data. I guess I'd have to make a system to recreate it from scratch

[young knoll]

You’d probably have to get the players scoreboard, figure out what team they are on, and get the prefix and colour from there

[fast jasper]

that's definitely what vanilla is doing already. wish we had access to that method

but alright I'll try that thanks

[chrome beacon]

You could probably make a PR if you want to

[wet breach]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#setDisplayName(java.lang.String)

add color in here and it will change their color of their name

this is only used in plugins and chat. There is another method to change their playerlist name as well

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#getPlayerListName()

this is the method to obtain the version you are most likely seeking

it helps if you would just search the Javadocs as it does have a search bar other then just looking at the interfaces

[young knoll]

They did say they tried getListName

Considering getListName isn’t a thing I assume they meant getPlayerListName

[wet breach]

idk, but it will include color in it as it grabs the exact data that is set. The only way it wouldn't is if you are making use of packets to do all these things instead and thus the server is unaware of these things

so if they are using packets to show a custom player list to players for example and they modify how the names are shown using only the packets

then the server wouldn't have any information in regards to color since it was never set using the api

[fast jasper]

I am using 1.8.8

[rough ibex]

Why

[fast jasper]

but appreciate the resource

[rough ibex]

Luckily it will work

but 1.8 in 2025 omegalul

[wet breach]

those methods exist on 1.8.8

and hasn't changed in functionality

[fast jasper]

oh sorry i didn't realize you sent me documentation

I thought you sent me an API or external plugin

okay, I tried all these methods already btw

they all return the same thing

[wet breach]

are you using spigot and do you have any plugins modifying packets?

[fast jasper]

yes I'm using Spigot

and everything else is 100% vanilla

[wet breach]

then not sure what you are doing wrong because I never had an issue in regards to chat where their color is not being set unless you have some other plugin interfering

it has always been a thing you use SetDisplayName to change their name/color in chat

or if you wanted to show their name in color in a message you would grab their display name

the only way the server wouldn't know about a players color is if you weren't actually using the api to set the color of their name to begin with

[young knoll]

They aren’t

They are using vanilla scoreboard teams

[fast jasper]

you're probably using PaperMC

[wet breach]

I don't use paper

don't make assumptions about people

I am probably one of the biggest supporters of using only spigot

[fast jasper]

sorry. my mistake

I should've worded that differently

[wet breach]

I went from CB to spigot. I have tried paper, but I don't like the development of it and some of its staff

I was once a BukkitDev staff member just like md_5 was long time ago 😛

[fast jasper]

I see. well that's pretty neat

[wet breach]

indeed, but that aside the api methods should work. Even though you are making use of scoreboards maybe try using the api methods to set their names too?

[fast jasper]

sorry for making an assumption out of nowhere. anyways yeah I'm on regular Spigot, 1.8.8, my plugin, and world edit are the only things in the server

[wet breach]

not sure if using the api methods would conflict but I don't think it would as the scoreboard should temporarily override even if you are setting the same colors

[fast jasper]

I am using Spigot to create and set the scoreboards as well

[wet breach]

I meant, using the api methods to set their displayname even though scoreboard overrides it

[fast jasper]

as well as the teams, their color, and prefix

[wet breach]

so that later you can use the api methods to obtain their color

[young knoll]

Like I said, grab the players scoreboard, get their team, and then get the color and prefix of said team

[wet breach]

or do that

that sounds lot better

[fast jasper]

yeah that's what I'm working on rn

I'll probably just do that approach tbh

[wet breach]

either way, the api methods do work, just can't expect it to grab data it doesn't know about

with that, I am off to work now 🙂

[wet breach]

in case you need a way to look at the javadocs better for that version even though I don't like people using outdated versions

here is this link

https://helpch.at/docs/1.8.8/

unfortunately doesn't have the search function

[fast jasper]

that's fine I can control + F. thanks for that resource. I think I may have visited this before at some point

[tranquil stump]

Does anyone know how I can change the keybind to accept autocomplete answers using ctrl+y in IntelliJ?

[river oracle]

do some people really use ctrl+y 💀 mine is just tab

it'll be under hotkeys

[tranquil stump]

it's vim

[river oracle]

probably "Complete Command"

under keybinds

vim has the most wild hotkeys lo

though if you want vim hotkeys just use the vim hotkeys extension

[tranquil stump]

i'm trying to but the ctrl y doesn't work idk why

[river oracle]

i'd seek support from the intellij forums or support page

[tranquil stump]

alr i figured it out

it was called choose lookup item

[wet breach]

Is this your twin @blazing ocean

[mortal hare]

this is why inheritance sucks

it works fine until you get shit like this

[river oracle]

Yeah

Uhuh

[torn shuttle]

I think I broke deepseek

[torn bough]

How would I go about making a plugin that removes dolphins needing to go up for air?

I know how to "make a plugin" with commands and modded items but what I'm asking for is the logic that controls the dolphin mob

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/LivingEntity.html#setMaximumAir(int)

Probably just set these to Integer.MAX_VALUE or smthing

[smoky oak]

is it possible to return the ResultSet of a SQL query, if within the method you try-with-resources the prepared statement?

[eternal oxide]

Not really. pass a consumer into your method to process the ResultSet

[smoky oak]

bleh

return List<Object> it is

oh btw assuming a List<Integer> is stored in a List<Object> can you just cast it like you would primitives?

ie (ArrayList<Integer>) arrayList

[eternal oxide]

casting would be unsafe. Probably better to stream.map

[smoky oak]

well, i have a check that guarantees it's in that format

i just want to deduplicate the function

specifically, there's a final field that guarantees its, for example, ArrayList<String>

(aka: what about it is unsafe? the way my code is structured might be able to circumvent it)

[eternal oxide]

The returned Object may not be a parsable String to an Integer

[smoky oak]

ah

im not tryina cast string to int

i have a List<Object>, which i have a final field stating of what type 'Object' is

so i was wondering if i could just go if(field == STRING) -> (ArrayList<String>) cast

(workaround to not have to copy and paste the same function for every type it can be)

[eternal oxide]

If your original is a List<?> yes, but unsafe cast. If it is List<Object> no

[smoky oak]

uh
how does ? work again

[eternal oxide]

its anything

Object means it IS an Object

[smoky oak]

wait

primitives arent objects

riiiiight

can this be done with generic signatures somehow?
ideally I'd have one method spitting out List<T> but i cant figure out how to input the desired T atm

[eternal oxide]

I'd still recommend you downcast using stream

if you are passing a Type (Integer) you can .map(type::new)

however ARE you talkign about Integer or int?

[smoky oak]

resultset can spit out Object in place of int i guess?

basically im trying to do this

just.. yknow, working

bc the alternative is to duplicate this function for every possible SQL type instead of just having to put the values into the switch

or as before, return object which also isnt ideal

[eternal oxide]

Yeah you can;t easily cast T so your return is goign to be problematic

[smoky oak]

thats the crux. since my generic is Class<T> i wouldnt get primitives so i could have an intermediary in List<Object> but how tf do you cast to T lol

[eternal oxide]

if I were you I'd return the List<Object> and stream cast once returned

[smoky oak]

i mean i could but the idea is to have this data manipulation in here, so you dont have to deal with those casts upstream lol

[eternal oxide]

then there is no need to pass in T

[wet breach]

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
    try {
        return clazz.cast(o);
    } catch(ClassCastException e) {
        return null;
    }
}

[smoky oak]

that could work. Assuming o is instanceof clazz, can this throw the exception?

because if not, ill throw a runtime exception stating to not use reflection bc with the checks in place it cant hit it otherwise

[wet breach]

example how the above would look when using it

final Class<int[]> intArrayType = int[].class;
final Object someObject = new int[]{1,2,3};
final int[] instance = convertInstanceOfObject(someObject, intArrayType);

[smoky oak]

does this work for collection datatypes too? i could return an array, but the situation is much more suited to arraylist

(im assuming yes but at this point i dont trust java as far as i can throw it lol)

[wet breach]

it should work

anything passed to that method I gave above will have the compile time type Object

if you are still unsure I can show you the byte code of it

[smoky oak]

nah thats not why im asking, its just that java is jank

[wet breach]

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
        try {
            return clazz.cast(o);
        } catch (ClassCastException e) {
            return null;
        }
    }
    public static void main(String[] args) {
        String k = convertInstanceOfObject(345435.34, String.class);
        System.out.println(k);
    }

byte code of this is as follows

public static <T> T convertInstanceOfObject(java.lang.Object, java.lang.Class<T>);
    Code:
       0: aload_1
       1: aload_0
       2: invokevirtual #2                  // Method java/lang/Class.cast:(Ljava/lang/Object;)Ljava/lang/Object;

    Exception table:
       from    to  target type
           0     5     6   Class java/lang/ClassCastException

    Code:
       0: ldc2_w        #4                  // double 345435.34d
       3: invokestatic  #6                  // Method java/lang/Double.valueOf:(D)Ljava/lang/Double;

      18: aload_1
      19: invokevirtual #10                 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
      22: return

[smoky oak]

i... think i understand it?

been a while since i looked at anything low level

btw, would it be better to cast the list directly or to stream it?

ie return results.stream().map(e -> genericCast(e, clazz)).toList();

[wet breach]

depends, but streaming it might make it easier to understand in case you forget about it lol

doubt there is any significant drawbacks to either method

[smoky oak]

i think it makes more sense to direct cast it th en

uh

how do i get the class of a list lol

[wet breach]

List<String> myList = new ArrayList<>();
Class<?> listClass = myList.getClass();

[smoky oak]

im clearly doing something wrong here

and it wasnt forgetting to make it an arraylist

[wet breach]

I don't have my IDE opened, so can't really check lol

but, it seems you have an array list already from your above code

you have ArrayList<T>

so just grab the class from there

[smoky oak]

thats a ArrayList<Object> unfortunately

[wet breach]

well I guess you would have same problem, replace ? with T

should work I think

[smoky oak]

nope

[wet breach]

lol

and this is why I hate messing with generics

[smoky oak]

yeeea but i really dont want to have to write O(n) functions lol

map it is i guess

btw sanity check, its Integer.class coz getObject from set returns Object, right?

or do i need to make separate calls for integer entries

[wet breach]

Class<? extends Object> clazz = items.getClass();

the annoying part with generics is the type erasure which in this case T gets removed

and without using reflection, it isn't a very straight forward way to get what you want XD

[blazing ocean]

did you write this by hand

[wet breach]

no

[wet breach]

javap -c com.mypackage.MyClass

[blazing ocean]

ah yea

[wet breach]

this will show you the bytecode for a given class

[blazing ocean]

I just got confused because you said you didn't have your IDE open

but yea I always forget about javap

[wet breach]

right, I just used notepad to make a simple class

since I wasn't making anything complex lmao

[misty ingot]

how could i go about making an API for my plugin that other plugins can plug into and interact with the plugin in some specific ways?

[remote swallow]

Add methods that plugins can interact with inside your plugin or create an api module that has the backing for this that they can get from your plugin

[sinful iron]

hello i got questions on prepareAnvilEvent where my result item stuck in the result slot when trying to get them out

[smoky oak]

public static methods

s what i use at least

[echo basalt]

I expected better

[misty ingot]

i dont think public static methods is the best way to do it....

[smoky oak]

illusion its been two days lol

[misty ingot]

an API module might be the way, but how would people use it? ive never exactly made any sort of package

[echo basalt]

You're still breaking my expectations every day

[smoky oak]

do you know if jeff by chance has a post about doing library modules?

[misty ingot]

com.siliqon.pluginName.api.aReallyFancyMethodWow

[echo basalt]

The fancy proper way is having an API module full of interfaces and inject them using something like bukkit's service system

[misty ingot]

jeff might have something about APIs

[misty ingot]

thats cool and all but like
how would i do that

any tutorials or guides?

[smoky oak]

(jeff doesnt seem to have anything, its multiple nms versions using modules is the closest on his website)

[smoky oak]

would that change how you use those api methods? or could you still just go 'scope provided' and call the methods

[sterile axle]

this is way super old, but, like, yeah. it still works this way

https://bukkit.org/threads/services-api-intro.26998/

[bitter crater]

[smoky oak]

?nohello

[smoky oak]

?ask

[undone axle]

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question. Create a thread in case the channel is already in use!

[sterile axle]

basically make your interface, register it in your plugin and provide impl class. then anyone who wants to use your service just depends on your plugin in plugin.yml, adds your api pom as a dependency to their project, and gets your impl from the bukkit service manager while declaring your interface as the type

[wet breach]

https://github.com/frostalf/servertutorial

[sterile axle]

dis is da wae (TM)

[echo basalt]

Exposing the api is simply for hiding code flow and building something long-term

[wet breach]

the link I provided has an api module

the api module for it to work your main plugin has to implement it

otherwise the api never gets values etc

[echo basalt]

Here comes frosty sharing that one repo he has

[sterile axle]

we're talking about the bukkit service manager

your repo does not show that, so it's not applicable here

[wet breach]

oh service manager

thought we were talking about providing an api module and how you do that

[smoky oak]

well more like how to do api properly in general lol

[echo basalt]

Interfaces n shi

[sterile axle]

alright well, if you wanna go outside of service manager, then sure look at frost's repo

anyway im going back to netflix bai

[bitter crater]

i have a question, i'm hosting a server in my community. i was wondering if how can i integrate the fog and ash effects in basalt biome in nether onto a world and not affect other worlds. i'm specifically doing this in my lobby, and exlude the smp world.

[echo basalt]

Practice dependency inversion and just throw the interfaces into a separate module

[smoky oak]

you might get mileage out of changing the biome

[wet breach]

I wouldn't necessarily say my repo follows strict proper stuff, but it shows you how to provide an API for others to use

[echo basalt]

Fog and ash are biome related

[bitter crater]

although i can use resourcepack, or /particles. resourcepack affects all world, and /particles is too complicated to setup with skript.

[wet breach]

also its open source that if you want to copy it you can as long as you give credit, think that is the minimum MIT requires

[echo basalt]

[bitter crater]

is it possible to change the biome on a world without changing the actual world

?

[echo basalt]

✨ packets ✨

[warm mica]

I don't think there is a packet to change the biome dynamically, whereby you would have to painfully modify the chunk packets

[bitter crater]

my vision was the lobby is a ship, and the fog and ash on the basalt biome really fits the theme. like a ghost ship

if it's not possible, is there anymore way to make a weather fog on minecraft? any server sided plugins?

in just a specific world?

[wet breach]

you can just change the biome for a block or set of blocks or chunk or set of chunks only

just fyi

so you could just set your lobby as the appropriate biome and leave everything outside of that untouched

[warm mica]

Yeah. Worldedit's //setbiome command could help you with that

[bitter crater]

i could try that

[wet breach]

you can use that, or make use of the spigot api to do it if you want to make a small plugin to do that lmao

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/Block.html#setBiome(org.bukkit.block.Biome)
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#setBiome(int,int,org.bukkit.block.Biome)

first link is for setting blocks to a specific biome, and the second is if you want to set an entire chunk to a certain biome

[bitter crater]

thanks dude, my friend didn't know this is possible

now we can make it

[wet breach]

have fun and enjoy your creation now

[bitter crater]

and last question, are particles really controlled on command blocks only?

[wet breach]

if you don't want to use a plugin

[bitter crater]

is there a plugin for that?

[wet breach]

otherwise there is a variety of plugins and libraries available as well as various api methods if you want to make something yourself

[young knoll]

There’s even a vanilla command for setting the biome now

[sinful iron]

hello i got questions on prepareAnvilEvent where my result item stuck in the result slot when trying to get them out ?

[wet breach]

oh really?

thats new for me

[young knoll]

Yeah

/fillbiome

[wet breach]

that naming however isn't quite fitting

but good to know lol

[warm mica]

You could try to use InventoryClickEvent for that

[sinful iron]

oh yes, i also have that part in, but still cannot get it work... do we need to handle the exp cost ? cuz i saw all the cost functions are deprecated

i felt like im missing something

[bitter crater]

another hindrances in our build, we want to spice things out. if you know god of war, when going inside the smp world we want to integrate the particles to atleast make some visuals on the portal room.

[wet breach]

just search around on spigotmc or use google. Bound to find some kind of plugin already made that can provide what you are looking for in regards to particles

[misty ingot]

are you trying to make the ghost-ish ship from helheim from GOW5

[sinful iron]

cuz im making a re-roll function on items where only apply when onInventory click, i can tell the inventoryclick event triggered, but the item still stuck ;-;

[wet breach]

if nothing else you can make it yourself

however unlike your biome request particles are bit more involved

[young knoll]

I believe you can’t take the item out if there is no cost set

So you have to set it to at least 1

[bitter crater]

trailing particles on the floor as if it is like a lightning, and after this lightning thingy touches the lectern it shoots out a shulker bullet in the portal. we added custom datapacks that added custom particles.

[bitter crater]

nah its kind of a mix match tbh, mix with pirates of the carribean, god of war, and idk what is

[warm mica]

You could try to remove the item from the result slot and instead set it on the players cursor

[sinful iron]

oh thankss, i was looking into it too but arent the setCost from the event are deprecated ? if so what should i use ?

[bitter crater]

nothing, they are all command based. we could not find sources on plugins

[wet breach]

deprecated doesn't always mean unusable

[bitter crater]

or im very blind

[young knoll]

Use the AnvilView instead

[sinful iron]

imma try out Jishuna method, hopefully that works, if not gonna go for this hahahaha

[wet breach]

also, in case you wanted it to cost nothing, you can set the cost to 1 and this use this event I believe to refund them the cost
https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerExpChangeEvent.html

[young knoll]

Event#getView

[sinful iron]

ahh fax

[sinful iron]

alrighty, thankssss, will try that outtt

[warm mica]

If i remember correctly, that only gets called for dropped exp orb

[misty ingot]

how could i go about getting the current selection that the player has made in FAWE/WE?

[wet breach]

oh, that sucks then the description was a bit misleading then

lmao

[young knoll]

Use their api

[misty ingot]

i cant figure out what to do in their api to get the player's selection

[sinful iron]

YEEEP, it works, thanks ;-;

👍 👍 👍

[young knoll]

https://worldedit.enginehub.org/en/latest/api/concepts/local-sessions/

https://worldedit.enginehub.org/en/latest/api/examples/local-sessions/

Conveniently getting a players selection is the second example

[misty ingot]

nice

and lets say i wanted to save this selection in a file so that it can be retrieved at any time and put into a new world?

[wet breach]

it depends on worldedit, so you would use worldedit api to get the selection

which in WorldEdit, its CurrentSession I think it was? Something with Session in its name.

[misty ingot]

i got the getting part above, but i also want to save it as a file so i can get the selected area any time i want and put it in a world wherever i want

[young knoll]

They have an api for schematics too

[wet breach]

then look at how world edit saves schematics

[misty ingot]

oh i see the example

[wet breach]

and Jishuna beat me to it -.-

[bitter crater]

tried that //setbiome on worldedit and faced with an error "java.lang.NullPointerException: null"

nvm it worked, but idk how to do the fog

anybody know how to do a weathered fog?

[misty ingot]

there should be a packet for that

[bitter crater]

how can i know that?

[misty ingot]

https://tenor.com/view/saucerswap-larry-defi-crypto-hbar-gif-26791945

[bitter crater]

huh?

[misty ingot]

https://www.spigotmc.org/threads/fog-and-packets.563573/

this might help

[bitter crater]

is it still applicable on 1.21.1?

[pseudo hazel]

probably

[bitter crater]

why does java just not make an on and off switch

for fogs

[misty ingot]

i dont think thats how it works

[blazing ocean]

Yea I'm just checking there

where are you seeing said 0x0C

[molten hearth]

0x07 is the actual packet ID for registry data (and im expecting a registry data packet)

for some reason there's 0x0c before the 0x07

(also just saying I disabled both encryption + compression server-side)

[chrome beacon]

Yeah I'd assume that's the length

[molten hearth]

wait a minute

the length can take up two bytes?

i didnt think of this ☠️

It's a varint

so yes

a truly foreign concept to java developers

just making a bot that can log onto servers

it doesnt really need to know of whats going on it just needs to follow the login sequence and then disconnect

but why

[molten hearth]

oh this is for my mc scanner project

i already do netscans but I also want to test the validity of the results

and there's no efficient tool to do so at least that I saw

why cant i player#sendMessage while simultaneously having a conversation with the player

what does that even mean

„having a conversation“

is that a feature you made?

conversation api I assume

[misty ingot]

ok so

inside my StringPrompt, i have a condition so that if the player enters the thing i dont want em to enter i player#sendMessage them a message telling them whats wrong so that next time they enter it correctly
but the message never shows in my chat

[valid burrow]

have u made sure its actually ran

log a console message right before

to make sure it’s actually being called

if that doesnt help make sure its the right player

otherwise

Why do you need to access villagers in unloaded chunks

[manic delta]

i want to make something like shoopkeepers

so i need to acces to the villager after server restart

or wait

i can save the entity id and detect the rightclick?

            @Override
            public @NotNull Prompt acceptInput(@NotNull ConversationContext conversationContext, @Nullable String s) {
                ...
                int teamSize;
                ...
                if (teamSize < 1 || teamSize > 8) {
                    sendMessage(player, plugin.LANG.getEnterValidTeamSize(), true);
                    return this;
                }

                ...
            }

yes it runs.
sendMessage is supposed to send them a message, that method itself works
but i get no message
