Two things:

• Keep it simple, stupid.
• "Premature optimization is the root of all evil." -Donald Knuth

[hasty prawn]

Could make an item builder method

Or class

Whatever floats ya boat

[quaint mantle]

not a bad idea lol

[lavish hemlock]

(Full quote is: "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%")

[hybrid spoke]

BasicCrateMaker BasicKey

why is the B uppercase

[lavish hemlock]

Basically, JD

Optimize when you can tell there's a problem with performance

[hasty prawn]

^

[quaint mantle]

alr

ill leave it be then lol

[hybrid spoke]

nooo

never

don't do that

[smoky oak]

guys?

[hybrid spoke]

optimize where you can when it works

dont try to optimize while making it work

[lavish hemlock]

That's what I meant

[hasty prawn]

I mean the quote does say that given an opportunity, you should optimize the 3%

But it's not the most important thing

[lavish hemlock]

Although actually

[hybrid spoke]

optimization can already be the simplest refactoring what has in the most cases nothing to do with the performance

[lavish hemlock]

It is kind of a good idea to fix some performance issues when they arise, since they can affect testing

Like

If it takes 5 minutes to test something when it should only take 30 seconds...

Yeah

[hasty prawn]

I suppose that depends on a case by case basis though

[viral crag]

you mean the remapped -mojang ?

[ivory sleet]

Yeaa

[fallen agate]

yeah I found the solution

. (no ping)

[smoky oak]

can someone answer my question now...

[viral crag]

sure

[opal juniper]

he does

[hasty prawn]

Probably the releases page

[viral crag]

do you have another one? 😆

[hybrid spoke]

i dont

[smoky oak]

if releasing on spigotmc, use github releases or github download link as resource link?

[viral crag]

what are you trying to pull from github? - oh

[hybrid spoke]

just upload the jar 🤔

[viral crag]

releases would be the better choice

[smoky oak]

thank you

[viral crag]

do you have github setup for it though?

[smoky oak]

yes

[viral crag]

there you go, then it should handle updates for you - or atleast that is the purpose of github releases

[fallen agate]

Is there any api where I can check the latest version of spigot and build it when it releases?

[ivory sleet]

GitHub actions 😌😌😌

[fallen agate]

Oh yeah

[ivory sleet]

Oh yeah that wasn’t to you specifically

[fallen agate]

lol

[ivory sleet]

But just needed to shout GitHub workflow out

[visual tide]

public static 
        void main(String agrs [])

[hasty prawn]

agrs... How dare you.

[fallen agate]

also... strange question but can I not use NMS? I'm trying to spawn a village

It's annoying

[hybrid spoke]

[visual tide]

oh wow

[smoky oak]

dont think so

unless you use libraries

[visual tide]

isnt there some structure api thing

[smoky oak]

oh on that topic

[lavish hemlock]

Funnily enough, the stdlib uses This shittyStyle[] pretty commonly.

[smoky oak]

anyone knows why datapacks suddenly broke from 1.18.1 to 1.18.2?

[viral crag]

forward or backwards?

[smoky oak]

I can't start my perfectly fine 1.18.1 server in 1.18.2 unless i remove the datapacks

one sec imma dig up the logs

[viral crag]

I mean were they built against 1.18.2 or an earlier version?

[smoky oak]

1.18 i believe

?paste

[undone axle]

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

[lavish hemlock]

JDK internals are also fans of 3k line class files :)

[smoky oak]

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

wait

is spigot GPL 2 or GPL 3

[viral crag]

thats just a warning btw

[smoky oak]

no it literally doesnt start

[viral crag]

thats not the cause

[smoky oak]

the only thing i changed was removing the datapacks

[hasty prawn]

Maybe one of the tags got changed? Maybe check the 1.18.2 change logs and see if there were any changes

[dire salmon]

Um
https://paste.md-5.net/ixaqajuxar.java

[smoky oak]

that's literally the last message in the log

[viral crag]

java.util.concurrent.ExecutionException: com.google.gson.JsonParseException: Error loading registry data: Not a tag id a missing tag id itself is not enough to stop from loading

[smoky oak]

this

server crashes after that

no further messages or warns

[viral crag]

and,.... that doesnt mean thats where it crashed

[smoky oak]

dude

there's literally two messages in the log

[hasty prawn]

You almost crashed my phone god damn 🙄

[smoky oak]

[08:40:24] [ServerMain/INFO]: Environment: authHost='https://authserver.mojang.com', accountsHost='https://api.mojang.com', sessionHost='https://sessionserver.mojang.com', servicesHost='https://api.minecraftservices.com', name='PROD'
this and the other

after that

ded server

[dire salmon]

Pog

[hasty prawn]

LOL

How many datapacks do you have Moterius

[tardy delta]

AAAAARGH

[smoky oak]

also is it normal to get 1 download per 3 minutes on your first plugin

[smoky oak]

1

[hasty prawn]

1 file?

[smoky oak]

yep

wel

one zip file

[hasty prawn]

?paste it

[undone axle]

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

[hasty prawn]

The Json files

Or mcfunction whatever it's called idek

[smoky oak]

dont think paste.md is gonna cut it

it's amplifed nether

[hasty prawn]

Oh

[smoky oak]

but again

start message

error message

dead server

and removing the datapack 'fixes' it

[viral crag]

and the system log says java process is being killed

[hasty prawn]

Well, check the change logs then and see if something was modified.

[smoky oak]

it says something about changing from datapack v8 to v9

and about allowing the use of tags instead of id

[dire salmon]

:NotLikeThis:

Ah nonitro

[hasty prawn]

Well that's probably your issue

And you need to update the version

[smoky oak]

thats not my datapack

[hasty prawn]

You can still change it

Either you have to update it yourself or wait for the developer to do it and release it

[crimson terrace]

if you just uploaded it its still on the front page basically so for an hour or so, yeah

[rich inlet]

How do I show a subtitle to a player? This doesn't show anything:
player.sendTitle("", "§6Subtitle!", 5, 12, 3);

[smoky oak]

well i did something super simple

i expected exactly one download

from the person that wanted it

[crimson terrace]

it shows something for a second if you actually call it

[viral crag]

lots of people collect bugs and exploits

[smoky oak]

intentionally made bugs?

[viral crag]

yup

[smoky oak]

well then

[rich inlet]

For me this does not show anything

[crimson terrace]

well the error is not in the code you sent, so you will have to supply more info or code

[rich inlet]

Everything else around this line works just fine, there is also no console error

[viral crag]

where are you sending it?

[crimson terrace]

what did you assign player to yeah

[rich inlet]

public void onRightClick(PlayerInteractEvent event) { Player player = event.getPlayer(); //.... }

[crimson terrace]

any if statements?

send the entire method if possible

[rich inlet]

Yes, but every other line of code within the if statement gets executed perfectly

[viral crag]

Sends a title and a subtitle message to the player. If either of these values are null, they will not be sent and the display will remain unchanged. If they are empty strings, the display will be updated as such. If the strings contain a new line, only the first line will be sent. All timings values may take a value of -1 to indicate that they will use the last value sent (or the defaults if no title has been displayed).

might want to put a space or non display char for title

[rich inlet]

I can try that

[crimson terrace]

well its not a null value but an empty string

so it should still work

[rich inlet]

I thought so too

[viral crag]

should, i do not trust java in that respect though

[rich inlet]

Works with " " :)

Thank you all! :)

[viral crag]

your tick times are also awfully short

[rich inlet]

I know but thats intentional

[viral crag]

okay, 1/2 a second might not show on some clients

[crimson terrace]

its a full second

[rich inlet]

20 ticks = 1 second

[crimson terrace]

including fade in and out

[viral crag]

ah yeah

i was only looking at the stay

[rich inlet]

Thanks @crimson terrace and @viral crag :)

[crimson terrace]

np, couldnt expect an empty string to be equal to null in that method

[viral crag]

well ...

In Java programming, null can be assigned to any variable of a reference type (that is, a non-primitive type) to indicate that the variable does not refer to any object or array.

A String in Java is actually a non-primitive data type, because it refers to an object. The String object has methods that are used to perform certain operations on strings.

so based on that you can assign a null to a string

[crimson terrace]

you can assign null to a string

[lavish hemlock]

Strings are just ✨ special types

[crimson terrace]

but "" is not null

[lavish hemlock]

Yeah

[crimson terrace]

"" is an empty String

[viral crag]

I do not see any rule that actually says that

[lavish hemlock]

Well

[crimson terrace]

its an object of the type String

which is not null

[lavish hemlock]

Any string literal should never return a null value

[crimson terrace]

unless im returning to monke

[lavish hemlock]

That would likely be a fault of the compiler

(I don't even know how the compiler would mix up ldnull and ldc)

So, even if it's not bound by the JLS/JVMS, it is still practical that "" is not null

[crimson terrace]

String string = null; //a null object, string == null returns true
String string = "" // an empty String, string == null returns false

[lavish hemlock]

If "Hello, World!" can't return null, neither should "" as "" is no more special than "Hello, World!"

[viral crag]

"We consider a string to be empty if it's either null or a string without any length." is from Baeldung

[lavish hemlock]

Yeah but that's empty, not null.

It's not "String is null if without length"

[crimson terrace]

that says that a null String can be considered empty, not that an empty String is null

[lavish hemlock]

^

Also a lot of shit would break if "" returned null

It is typical to use an empty string when one wants to avoid nullability issues but also pass an empty value

[viral crag]

From Java 7 onward, the recommended approach is to use the String.isEmpty() method to check for an empty string in Java. To avoid NullPointerException

[lavish hemlock]

isEmpty() does not avoid NPEs

[viral crag]

i am aware

[lavish hemlock]

Neat fact though

Kotlin's type system allows isNullOrEmpty() to exist

[crimson terrace]

i think that String.isEmpty() method is just there so that its neat XD

[lavish hemlock]

Yeah, I'm pretty sure it's the equivalent of s.length() == 0

Later versions of Java have isBlank() as well iirc

[crimson terrace]

s.equals("")

[lavish hemlock]

which also applies to situations like " "

[viral crag]

it is likely there because I cant find a rule in java that actually states what it is supposed to be

[ancient plank]

null is my love life

[crimson terrace]

in one sentence you described perfectly what I couldnt in like 5

[crimson terrace]

I feel that, fellow gamer

[smoky oak]

to the guy who invented null

thanks for nothing

[viral crag]

all I really know is that empty may or may not be null, but it will never be false

[smoky oak]

in true programmer fashion

i stole it

nah most of that is original at this point

oh scrape

[viral crag]

true programmers concurrently develop

[smoky oak]

im getting creative

[crimson terrace]

no need to get creative, just /gamemode creative

https://media.discordapp.net/attachments/620576156613345310/940806269286105158/medium.gif

😂

[smoky oak]

can't tell if you just found that randomly or are a brony

[crimson terrace]

I saved that crap, its pure gold

[smoky oak]

which answers the question not

[crimson terrace]

saved that gif along with this next one

[raw ibex]

what's the event for when someone right clicks a bock

[viral crag]

that was book and not block ?

[raw ibex]

lmao

[ancient plank]

doesn't matter if its a book or a block

either way it still uses the interact event

[viral crag]

true but i wanted to know

[smoky oak]

there's a lotta stupid things in CS

ASCII everyone

[crimson terrace]

wait is that true?

I think someone is laughing their ass off every day for having done that

[smoky oak]

probablz

on a more serious note

how do i initialiye an emptz emum set

[crimson terrace]

damn you slipped over a letter didnt you

[smoky oak]

_

wait

someone changed mz kezboard language

better

[viral crag]

the bock broke em

[crimson terrace]

nice

[smoky oak]

anyways

empty enum set?

[crimson terrace]

the power of bock compells you

[viral crag]

https://docs.oracle.com/en/java/javase/17/docs/api//java.base/java/util/class-use/EnumSet.html

[smoky oak]

yep

i think that's the first time i used SomeClass.class in code

[viral crag]

@smoky oak is that your clone in help-server?

[smoky oak]

im unsure what you mean so probably no

[viral crag]

same tag-id error from datapack

[smoky oak]

could be

dont remember

[kindred valley]

how can i take the dropped item in dropevent

[smoky oak]

event.getItemStack or something like that

[undone axle]

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

[kindred valley]

this does not work with isSimilar method

[viral crag]

you should link us to the 1.7 api so we know what exists

[crimson terrace]

masochists

[kindred valley]

https://helpch.at/docs/1.7.10/

[viral crag]

aha!

[tardy delta]

is there some class that wraps a number and a timeunit?

[kindred valley]

?

[crimson terrace]

just make one

[viral crag]

couldnt find it on spigotmc.org

[smoky oak]

can you escape an if?

[crimson terrace]

break;

I believe

[tardy delta]

escape?

return?

[smoky oak]

that ends the function

[crimson terrace]

I think break; might work

[kindred valley]

alr imma make it on 1.8

[tardy delta]

if else is something

[smoky oak]

tried

nope

[tardy delta]

you can only use break in a loop

if else lol

[kindred valley]

dont use while 🥴

[crimson terrace]

continue;?

[tardy delta]

thats loop thing too

[undone axle]

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

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[quiet ice]

continue is perfectly valid

though I am new to the convo so idk

[kindred valley]

🥴

[quiet ice]

If there is any context to this disregard my statement

[viral crag]

i do not even see a drop even in that api

[kindred valley]

there is

[tardy delta]

lol while(false) is an unreachable statement but if (false) is not

[crimson terrace]

thanks but no thanks, just never had to use continue, so never knew it only worked on loops

[kindred valley]

but limited

[crimson terrace]

i know

anyway, an attemptto answer it

[tardy delta]

😳

[crimson terrace]

int?
thats a powerplay

[quiet ice]

at that case you could just go with a while(true) loop

[kindred valley]

🥴

[quiet ice]

"" is a blank string and null is a null object

You cannot invoke any methods on the latter

But I think you know that already

[kindred valley]

do you recommend 1.8

yes, actual minecraft arenapvp on 1.18.2

cool

[viral crag]

well, i belive at least spigot 1.8.8 is patched against log4j

[quiet ice]

If 1.8 wasn't to crash that often I would recommend it - but right now I cannot

And custom clients make the crashing even worse. Like seriously, how can one fuck up that hard

You have like an entire decade to develop a stable application on a stale codebase and yet they fail doing that

like not crash minecraft but crash ALSA

[kindred valley]

how can i equal the dropped item and custom item

or do i can?

[quiet ice]

(I have no idea how mc manages to crash ALSA however)

Should report it to the maintainers but eh, too lazy

[quiet ice]

no idea. I bet you could if you were to read the documentation

PDC or other metadata (NBT?) comes to mind here

[viral crag]

in 1.8.8 you might be able to utilize the CustomName - and then manipulate teh itemstack i guess

[crimson terrace]

Oh Oh I know this one! I usually use the PDC to store any PersistantDataType and then check wether the itemStack.getItemMeta().getPersistentDataContainer().has the NamespaceKey I defined in my Items enum 🙂

[quiet ice]

On spigot that is

[crimson terrace]

lore comes to mind, so does the ScoreboardTags

[quiet ice]

Some forks probably have backported that api

lore isn't a good idea, even if it can be used for that thanks to legacy strings

[tardy flame]

Shouldn't that be a bool?

[quiet ice]

Probably not as that looks like a C-style enum constant

[tardy delta]

writing a discord bot kekw

stopped using the api for months and now i have to relearn everything 💀

[crimson terrace]

just remember to .queue() the messages you send via the bot😛

[glossy venture]

is there a way to include a folder following

+ libraries // root, i want everything in this folder to be included
  +- com
    +- example
      +- foo
        +- foo-6.9.1.jar

as a repository in gradle?

[ivory sleet]

jda yikes

[glossy venture]

the problem is that there are no poms

so i dont think a maven repo is possible

[ivory sleet]

yep

[tardy delta]

ye that hurt me for a while

[ivory sleet]

you can declare a flat directory repository

[viral crag]

wdym?

[crimson terrace]

im glad I had a friend explain that one to me XD

[glossy venture]

but will i be able to use it like

dependencies {
  compileOnly 'com.example.foo:foo:6.9.1' 
}

[quiet ice]

a repo does not require a pom

[glossy venture]

oh

[ivory sleet]

uh well

[quiet ice]

Poms are totally optional depending on your resolver

Of course it is better to have them however

[tardy delta]

my previous bot is from when i was a java noob so lets redo that 😌

[glossy venture]

ok thanks ill look into it

[ivory sleet]

this.dependencies {
  this.flatDir {
    this.dirs('com')
  }
}

this.dependencies {
  this.compileOnly name: 'FileWithoutDotJar'
}```

unsure if it works for nested dirs

[viral crag]

why dont you pull the maven into gradle the normal way?

[ivory sleet]

but else just walk the directory down and add each as a flat directory

[glossy venture]

ok thanks

wait is there a way to create a custom repository

with a custom resolver

[quiet ice]

why do you think that this isn't done this way?

gl, don't try that

[glossy venture]

ok i will try

[quiet ice]

Either you are writing tons of groovy or create a gradle plugin

[viral crag]

seems like a lot of extra monkeying to pull/put a project locally and then access it directly

[ivory sleet]

kotlin dsl x)

[glossy venture]

i want to include the libraries folder from the minecraf tserver directly

i have a 1.18.1 dev server

so i can just get it from there

[ivory sleet]

I mean gradle doesnt have a java dsl

and the groovy dsl just straight out is ass

[quiet ice]

compileOnly files("build/obftools/intermediary.jar")
^ but calls such as this one allows to include any arbitrary file

[ivory sleet]

ofc it could be good, but intellij made it suck sorta

[quiet ice]

yes. Though kotlin is also nonsensical to me

[glossy venture]

oh yea

[ivory sleet]

I dont like kotlin a lot, but when it comes to gradle I have to use it

[glossy venture]

i can just make a function that maps a string like com.example.foo:foo:6.9.1 to <dir>/com/example/foo/foo-6.9.1.jar

[quiet ice]

Sadly eclipse does not support kotlin gradle (WHYYYY)

[glossy venture]

and then use that

[ivory sleet]

yeah orby

[ivory sleet]

ah that also sucks

[tardy delta]

i forgot but is HashMap#put overriding older pairs with the same key or not?

[glossy venture]

how hard can creating a custom repo be tho

:)

[ivory sleet]

like kotlin got some god ascend features as well as some questionable things, its like yatopia basically

[quiet ice]

there is apparently a plugin that adds support for it, but last time I installed it everything has gone south.
Nowadays I am starting to maintain my own build tool anyways so now it's only an issue with 3rd party repos at which point using intelliJ can't be that bad

[tardy delta]

owh right it is

[quiet ice]

if you want one that doesn't you are looking for putIfAbsent

[simple anvil]

how do i read the contents in a txt file and put them in a book?

[crimson terrace]

BufferedReader I believe

[river oracle]

Buffered Reader would be a good option for reading from a text file

[worldly ingot]

Eclipse does have a Kotlin plugin which should allow you to write gradle files in Kotlin

Though really if you're writing in Kotlin, you're better off using IJ anyways

and that's coming from an Eclipse user

[simple anvil]

how do i use it, is it a dependincy?

[crimson terrace]

standard java

[river oracle]

Nah it's pure Java

[simple anvil]

kk

[river oracle]

Look it up google is your bestie

[crimson terrace]

StackOverflow is great

[simple anvil]

kk danke

[river oracle]

Hmhm

[quiet ice]

java.io.BufferReader or something like that

If you want to use nio, there is Files.newBufferedReader(Path)

[rich inlet]

Hi, my PlayerInteractEvent (when stepping on a pressureplate) is called way too often, I want it to call only once when you step on it. If you leave the pressure plate and step on it again it should be called again. But right now it spam-fires the event when you're standing on it. Is there a simple solution?

[quiet ice]

player move event perhaps

[rich inlet]

`
private final HashSet<UUID> activated = new HashSet<>();

@EventHandler
public void OnPressurePlateStep(PlayerInteractEvent event) {
if(event.getAction().equals(Action.PHYSICAL)) {
Player player = event.getPlayer();
UUID uuid = player.getUniqueId();
if(event.getClickedBlock().getType() == Material.LIGHT_WEIGHTED_PRESSURE_PLATE) {
if(!activated.contains(uuid)) {
activated.add(uuid);
//code
}
}
}
}`
Thats my code so far

[rich inlet]

I think that is considered very laggy

[vivid parcel]

Hello, I'm starting with spigot and a little with java and I don't understand where this error comes from, could you help me pls

public CommandMap getCommandMap() {
        try {
            if (Bukkit.getPluginCommand() instanceof SimplePluginManager) {
                Field field = SimplePluginManager.class.getDeclaredField("commandMap");
                field.setAccessible(true);

                return (CommandMap) field.get(Bukkit.getPluginManager());
            }
        } catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }```

[crimson terrace]

what is the error

[tiny wolf]

if I send a packet of setting an item in an inventory, I assume that none of the events of bukkit would work with it right ?

[quiet ice]

why would it?

It's only called at most once a tick per player

And the event handling overhead it minimal

[vague swallow]

what's the error?

[rich inlet]

As you see, I have a hashset where I add the UUID of a player when he steps on the pressure plate, and if he calls the event again and he is in the activated set, it doesn't execute the rest. now how do I remove him again, when he steps away from the pressure plate?

[crimson terrace]

as soon as you get a couple of lines of code going and have a bunch of players it uses a lot of resources

[vivid parcel]

says that if (Bukkit.getPluginCommand() instanceof SimplePluginManager) { is always false

[crimson terrace]

well

because it is

inconvertible types I assume

[quiet ice]

Even thousands of lines can compute stuff in sub-millisecond ranges

[vivid parcel]

So what i have to do XD

[crimson terrace]

you get 50 milliseconds per tick, thats not a lot when you think about it

and it always depends on how many players it runs for

[quiet ice]

You are underestimating the speed for a CPU

[crimson terrace]

youre underestimating the amount of plugins people have on their servers

[quiet ice]

With minimal amounts of allocations and carefully chosen data types everything is really fast

[ancient jackal]

I know it says you should not access Bukkit API when async but... is calling an event from another thread bad?

[viral crag]

https://javadocs.olziedev.com/spigot/1.18/org/bukkit/material/PressureSensor.html#isPressed()

[quiet ice]

It depends

Also, in this case checking whether a player moved from a pressure plate is going to be a call that takes a few nanoseconds at most

[rich inlet]

Ideas on completing this?

[glossy venture]

why is it complaining

about the variable

[quiet ice]

Player move event or just a scheduler

[glossy venture]

it says no candidates found for method call 'minecraftLibraries'

[smoky oak]

that doesnt look like java

[glossy venture]

groovy

in build.gradle

[quiet ice]

there is probably no FolderArtifacts#find method

[glossy venture]

there is

i made it

ok it works now

i love gradle :)

[ancient jackal]

okay it just doesnt work lol

[rich inlet]

okay, thanks

[viral crag]

are you not only affecting the objectives you set?

so you would only get the objectives you want on/for each

[ivory sleet]

^

ugh

from what I know you use one scoreboard instance

but you create more than one objective

and then change display slots for each one of them

[glossy venture]

it worksl

[ivory sleet]

[vivid cave]

hey guys, i'm using an interpreter called beanshell to debug java code interactively
But why do all the spigot/bukkit/paper methods are inherited from craftbukkit/nms kinda classes?
They do implement the same fields (more or less) in general, but still sometimes it's different

I'm assuming that this is made possible thanks to reflection right

So is there a way to reflect the actual classes (and not the underlying ones)?

maybe setting the classpath for beanshell or sth would do the trick? I really don't know

here is an example https://i.imgur.com/NumPWQL.png

as you can see it returns a CraftPlayer, instead of an org.bukkit.entity.Player

[tardy delta]

org.bukkit.entity.Player is an interface

[quiet ice]

CraftPlayer implements Player so no issue there

[vivid cave]

yeah, this was just an example

[quiet ice]

You can act as if it is a regular bukkit class

[vivid cave]

sometime it's annoying though cuz it misses fields

[sacred mountain]

currently i have a problem with dealing customized damage to all entities hit by a fireball.
my code works for the functionality part but i dont know how to cancel/remove the damage taken from the original explosion and then set the damage to my custom amount.

[quiet ice]

Why would it ever miss any fields?

[sacred mountain]

the event im using is the EntityExplode as i need to get total values for one explosion.

[quiet ice]

Bukkit is mostly built around interfaces so there are going to be few of them. And the few fields that you do have are private

[sacred mountain]

i tried using entitydamagebyentityevent but i couldntget it to work properly

[vivid cave]

I don't know, okay here is another example
When i use nms on beanshell, its fields are obfuscated, but as you know with mojang mappings, obfuscation is almost removed, just like when i code the plugin

[quiet ice]

cancel the event?

[sacred mountain]

that would cancel the fireball explosion not the damage

could i just get the entities last damage cause and remove that from the total damage dealt? idk

[quiet ice]

You can cancel the damage event

[sacred mountain]

how

[vivid cave]

anyway guys do u know how to fix this or do you at least know what's causing this

[quiet ice]

Which kind of fireball are you talking about?

[sacred mountain]

livingEntity.damage(truncatedRandomDamage - livingEntity.getLastDamageCause().getDamage());
prolly wrong but just an idea

[sacred mountain]

custom

[quiet ice]

Also why not rethrow the explosion event?

[sacred mountain]

i dont get what u mean

[quiet ice]

?jd-s

[undone axle]

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

[sacred mountain]

rethrow the event? why would i

[sacred mountain]

how does that help

[quiet ice]

Actually, I thought that there is a entity damage boolean there

Turns out there is only a fire boolean

[sacred mountain]

for htis ?https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityExplodeEvent.html

[quiet ice]

However still https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityDamageEvent.DamageCause.html#ENTITY_EXPLOSION

[sacred mountain]

yeah the isincendiary

[vivid cave]

okay i'm having the same issue than this guy https://www.spigotmc.org/threads/mojang-mappings-and-reflection.540538/
but no one answered the thread

[sacred mountain]

so what would i do with this?

                            livingEntity.setLastDamageCause(damageEvent);```

[quiet ice]

Oh, you are complaining about fields being obfuscated?

[sacred mountain]

im already using something like that for my event but

[quiet ice]

Do you want to damage entities or not damage entities?

[sacred mountain]

damage them

with my own damage amount

[quiet ice]

?jd-s

[undone axle]

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

[sacred mountain]

but i want the original damage from the fireball to be cancelled

but when im using the entityexplode event it has nothing to do with damage so im wondering if theres a way to get the damage dealt from the entities idk

[quiet ice]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityDamageEvent.html#setDamage(double)

[runic gyro]

how can i install datapacks for spigot to work on aternos?

[sacred mountain]

damageEvent.setDamage(truncatedRandomDamage);
this

[lost matrix]

[sacred mountain]

so that would damage the entity>?

bruh ok im dumb

[runic gyro]

how can i install datapacks for spigot to work on aternos??

[sacred mountain]

erm what

[lost matrix]

#help-server

[quiet ice]

TinyRemapper could help there

[runic gyro]

no one is responding

so sadddd

[sacred mountain]

1. aternos brh
2. datapacks arent spigot
3. plugnis are managed by aternos iirc

i dont think you can add custom ones

[runic gyro]

what server like not aternos are u recommending>

[sacred mountain]

i might be wrong its been years since ive used aternos idk

[sacred mountain]

your pc

is better than aternos

[runic gyro]

what?

[sacred mountain]

100%

[runic gyro]

hiw

how

[sacred mountain]

aternos gives you 2gb bro

[ancient plank]

#help-development is not the place for server help

[quiet ice]

But really unless you deobfuscate the jar (TinyRemapper) or obfuscate your reflection calls (probably not tiny remapper, but the same idea still applies) you aren't going to solve your issue @vivid cave

[sacred mountain]

i highly doubt you have less than 2 gb of ran

[quiet ice]

2 gb is quite a lot actually

[sacred mountain]

not for newer versions

[ancient plank]

my dev server runs on 2GB

[vivid cave]

but do u know what's causing that reflection modifies my objects classes in general? It feels like every of my objects is one abstraction level higher or sth

[sacred mountain]

yeah dev but i think they arent making stuff

[runic gyro]

okkkk i was just asking but anyways how to play with my friends with my pc

🤨

[sacred mountain]

port forwaring

ding

[quiet ice]

What exactly do you mean there?

[sacred mountain]

theres like 600 thousand tutorials on youtube just search it

[runic gyro]

ok then

[ancient plank]

used it as an smp with 40 ppl on 1.16 and used it as an smp with 10 ppl on 1.18 I'm just magic

[vivid cave]

as i told you, using beanshell doesn't output me the same object types that i would code them in; example Player is returning CraftPlayer
And the nms classes i'm using seem to be one abstraction higher in the sense that they are obfuscated, as the nms classes in my code work very fine with their new mapping

[lost matrix]

pf. Back in my day we still installed borderline virus virtual networks

[vivid cave]

so i'm wondering whats causig that

[woeful crescent]

will setting the meta of an item in a player's inventory update that item?

[ancient plank]

true that

[river oracle]

Fr

[lost matrix]

I forgot its name... Something with an H or M at the beginning...

[ancient plank]

hamachi is one

that's what I used most

[lost matrix]

Yes. That piece of invading garbage

[quiet ice]

The player <-> Craftplayer example is a bad one as you have already told.
And spigot reobfuscates the jar but you should already know about that if you are using beanshell.
So really what is your issue?

[vivid cave]

it's not a bad example because i don't get why this happens

understanding this may help me understand my nms issue

[quiet ice]

Player is the interface, CraftPlayer is the implementation

[vivid cave]

in my code i deal with Player, not CraftPlayer

[quiet ice]

Basically any CraftPlayer instance is a Player instance. YOu cannot have raw Player instances due to how java behaves

It is safe to either just checkcast all craftplayer instances to player instances or to just not cast them in the first place since the JVM does not really care about such details

Example for this would be

public interface Itf {

}
public class Impl implements Itf {

}

In this case all Impl instances would be an instance of Itf. It is fully valid to do

Impl var10001 = new Impl();
AnotherClass.itfConsumer(var10001);

if AnotherClass.itfConsumer is

public static void itfConsumer(Itf variable) {}

[silent stratus]

How can I disable the hit-cooldown? I dont want to do it with another plugin i want to implement this in my own plugin.

[quiet ice]

On a java bytecode layer the same applies:

NEW Impl
DUP
INVOKESPECIAL Impl.<init> ()V
INVOKESTATIC AnotherClass.itfConsumer (LItf;)V

is also valid

[ivory sleet]

geol, this almost deserves a pin

very good explanation

[vivid cave]

i see, thx for the explanaation!

[vivid cave]

i see:)

[grim ice]

no

u can user server pro

1gb is more than enough

[quiet ice]

Were you the one to use the celeron or am I mixing up people?

[grim ice]

me?

[quiet ice]

yeah

[grim ice]

u r mixing up

isnt a celeron some cpu thing

idek exactly what it is

wasnt it some cheap cpu thing or smth

[young knoll]

Yes

[quiet ice]

The Intel Celeron is just old

[grim ice]

oh

i dont use celeron

personal preference

[tardy delta]

are there even people coding like this?

I personally avoid such constructs at all times, but there are def. some people out there that do this

[golden turret]

nop

[vale cradle]

I used to run my dev server at 400MB

man, I miss 1.8

[north cipher]

Hello, I am trying to use a MySQL database for my spigot plugin, and I am trying to select many things but I would have to use a while loop, which would freeze everything. how could I avoid using a while loop? the guide on spigot (https://www.spigotmc.org/wiki/connecting-to-databases-mysql/) only selects one thing, but I am trying to select multiple things. my current code: ```java
try (Connection conn = FFDatabase.getConnection(); PreparedStatement stmt = conn.prepareStatement(
"SELECT coords FROM ff_claim_blocks"
)) {
ResultSet rs = stmt.executeQuery();
// can't do while loop here

[vale cradle]

what freezes the server is not exactly the loop, is the actual query. You need to run that on other thread

[golden turret]

bro

you need to do a big shit to freeze a server with a single while loop

[north cipher]

alr ive just been told to never use while loops

[vale cradle]

actually I didn't see the Statement, don't you use WHERE statements on your query?

or are you filtering whatever you want to look for on the loop? 💀

[north cipher]

i dont need to filter anything

its just a list of coords

[viral crag]

learn to use select and join

[north cipher]

ive used basic sql for a while

[vale cradle]

well the efficiency of your query is other topic but if you want to not freeze your server, as I said, do it on another thread

[viral crag]

no, make mysql do the work

there is no reason to parse what the database server can do for you

[vale cradle]

whatever he's doing he needs to learn how to do it on another thread first

if he says it's freezing his server, he needs to do it on another thread

[north cipher]

okay il do it on another thread

[vale cradle]

and learn how to use WHERE statements perhaps?

[north cipher]

theres no parsing involved in this, its just a list of coords?

i know how to use where statements, I just dont need to right now

[golden turret]

while (true) {
  for(;;) {
    new Thread() {
      @Override
      public void run() {
        System.gc();
      }
    }.start();
  }
}```

[viral crag]

poor programming is not going to be fixed by moving it to another thread

[golden turret]

the only while loop that can freeze or server

[viral crag]

that just burns your threads, there are lots of other ways to write blocking code

[golden turret]

Thread.sleep(Long.MAX_VALUE);

[vale cradle]

yeah, but Idk if it's poor programming or what, he hasn't told anything about what he's trying to accomplish

[viral crag]

he says it here

and he only needs 2 coordinates

[vale cradle]

And don't create new threads. Use CommonPools like the one provided by bukkit or the commonForkJoin pool of the CompletableFutures which I really recommend getting into it for comprenhensive Async operations

[golden turret]

it

was

a

joke

[north cipher]

might go with a better approach

if i cant get it working il explain with more detail

[golden turret]

but useful

[north cipher]

thanks

[vale cradle]

ik

[golden turret]

for new people

[viral crag]

all you need are the two diagonal coordinates and you know the rest

if you need multiple connected rectangles you ask for the diagonals of each rectangle

[golden turret]

any ideas on this?

i tried to run the code 1 tick after that

i want to get the killer inside the PlayerDeathEvent

[vale cradle]

I'd recommend just using the EntityDamageEvent

and checking if the entity's health is equal or lower than the final damage

PlayerDeathEvent is usually not as useful as the EntityDamageEvent

depending what are you trying to do

[golden turret]

i just need to get the killer

[vale cradle]

EntityDamageByEntityEvent then?

[golden turret]

actually

i just need generic player death

[vale cradle]

then try to get the killer a tick after the event is called?

[golden turret]

i just need the killer for a special damage

[golden turret]

#help-development message

see #help-development message

the killer is null

even after 1 tick

[vale cradle]

I just saw your code and the amount of times I tried to do something similar I just gave up and ended up using the EntityDamageByEntityEvent as I told you

cancelling the damage

and turning the player into spec

other solutions are just hacky workarounds

like the player.spigot().respawn()

[viral crag]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/profile/PlayerProfile.html#getName()

[vale cradle]

which now I think about It might be because of that

try getting the killer before respawn?

[viral crag]

unless you are using an old version

[golden turret]

bro

it was

because of the respawn

thanks

the .respawn() was setting the killer to null

_ _

i had no words

[sacred mountain]

me neither

[strange elk]

I'm trying to send to the player a pluginchannel message but I'm not receiving it, but it should be sending it normally because i get also after sending in my logs

beuh pastebin

imagine not centering ur name

idk mine breaks on phone

[viral crag]

why oh why ..

if you are using 1.18 player.getName() isnt a thing

its getDisplayName() or getListName()

yup humanEntity has it

why use player instead of humanEntity? despite most people want the DisplayName anyway

[golden turret]

[strange elk]

this was the only thing in the code that i pasted that doesn't work for some reason:

player.sendPluginMessage(CoreProtect.getInstance(), CoreProtect.COREPROTECT_PLUGIN_CHANNEL_REGISTERED, sendRegistered());

[viral crag]

or are you still getting it in the log/console?

[round finch]

@simple anvil do broadcast p.getDisplayName()

to see what it says

[viral crag]

returns teh default mojang one

[round finch]

do equalsIgnoreCase()

:d

then if you got a lowercase error it will be ignored

[viral crag]

supposedly, yup

[simple anvil]

im gonna leave the server

[round finch]

i knew it

basic rule of programming human error

[simple anvil]

well now forget it

it was never there

nothing happend

[round finch]

Lmao better

[simple anvil]

why

oh ok

uuid dont change

[viral crag]

btw, you could use the prejoin event as well ...

[round finch]

Bukkit.getPlayer(UUID).getDisplayname()

[simple anvil]

would that be better

what does that do

[round finch]

plus you don't need to update name for every time you changed your name

[viral crag]

runs on the initial handshake, would put the message slightly earlier

[simple anvil]

mk

[viral crag]

so you would get the message and spawn in at the same time

[simple anvil]

i think its deprecated

OMG

I SPELT IT RIGHT

[round finch]

if p == bukkit.getPlayer(UUID)

i recommend

[viral crag]

looks like they want you to use async for prelogin now https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/event/player/PlayerPreLoginEvent.html

it looks like all those offline servers need a UUID from now on: AsyncPlayerPreLoginEvent(String name, InetAddress ipAddress, UUID uniqueId)

it looks like all those offline servers need a UUID from now on:

what

[round finch]

e.getPlayer() == bukkit.getPlayer(Your_UUID)

[quaint mantle]

could someone help me in #help-server ?

[round finch]

you can even make a list and loop every UUID

[simple anvil]

821b7c98-9069-4ef4-b3a4-5665d2d01fda
or
821b7c9890694ef4b3a45665d2d01fda

why would i wanna do that

if you've more one uuid

[simple anvil]

no

[round finch]

note there exists a offline uuid 🤷‍♂️

[simple anvil]

whats the diffrence

both are the same one is with out the -

i dont know what to use

[round finch]

use your online uuid

if you're server is in online mode

[simple anvil]

im so lost

its a local server rn

im gonna pubish this so if a server has this pl and i join it says that

[viral crag]

sounds good!

[simple anvil]

sarcasim?

nope

it works and does what you want

[simple anvil]

kk thanke

use 821b7c98-9069-4ef4-b3a4-5665d2d01fda

i guess

thats yours

if you want to make a simple join message just use PlayerJoinEvent

[viral crag]

it was an alternate suggestion

[simple anvil]

ok

your onjoin was fine

yeah the join event, login or prelogin doesnt matter

I mean only benefit is that the async pre login is alr async in case you do some heavy stuff

does nothing, no error

[round finch]

yes

[tall dragon]

because that uuid aint valid like that

[simple anvil]

do it need the -

[tall dragon]

yes

[ivory sleet]

that will never be true

a UUID will never be equal to a string

not the way you're doing it at least

[simple anvil]

then how do i do it

[tall dragon]

either convert the uuid to a string first

[ivory sleet]

^

[tall dragon]

or convert the second one to uuid first

[ivory sleet]

I'd advocate that

[tall dragon]

idk whats faster tbh

[sacred mountain]

is there a difference/preffered between String.valueOf() and .toString()? i know some things cant be converted but should i try to stick to one

[ivory sleet]

String::valueOf is much more powerful

as it is in fact null safe

altho toString will be slightly slightly faster

tho generally, since Java's null is extremely unoptimized (not in terms of speed) you'd prefer valueOf

[tall dragon]

actually i have wondered what is better to do, a null check or use an optional

in sense of speed

[ivory sleet]

I use my own optional

just to avoid shitty null

[tall dragon]

ahh, i see

thats a pretty good idea

[ivory sleet]

I can show you actually if you're interested

nothing of particularity

but ye

[tall dragon]

yea, why not

would love to see how you handled it

[ivory sleet]

yeah j17 thing

(or 16 sth like that lol)

[tall dragon]

ah yea, i dont use that much yet

what does that actually do

[ivory sleet]

compile time enforcement of subclasses

[tall dragon]

Ah alright. Thanks for showing me. I might implement a similar system. This looks really nice

[ivory sleet]

😅 yeah nw, well Im still just trying it out, like code that uses sth like this/optional gets verbose extremely quick

[lost matrix]

bootleg optional?

[ivory sleet]

in principle

I did plan to add a lot more higher order functions

but just dont wanna sit there and guess code

[lost matrix]

Let it implement Stream

myeah true

not a dumb idea

[lost matrix]

Then you can apply mappings and what not

[ivory sleet]

yuh

[lost matrix]

interesting use of sealed. First time ive seen this used in a justifiable way

[ivory sleet]

I mainly made my own to make it polymorphistic towards differentiability for absence and presence

i dont want them to keep inventory

i just want 1 item not to drop when they die

[round finch]

get Drops
get Item

Store Item

remove item in drops

replace it back into inventory then respawning

[simple anvil]

List<ItemStack> drops = e.getDrops();

first step

right?

How can I make a gui someones inventory

like I create the inventory with the the type of player

but how can I make the players inventory and items show in the inventory

[simple anvil]

like /openinv?

[round finch]

you make a gui like this

Inventory inv = Bukkit.createInventory(null <--- Holder fx Player, 9<--- Size, "Example" <---- Name);

player.openInventory(inv);

@pliant oyster

i dont believe you make a PlayerInventoryGui like e
far as i know

but you can get a players inventory and open it as a chest

[pliant oyster]

I just realized I don't need to make it into a gui

[sacred mountain]

quick question, why do you get banned if trying to create a new spigot account

[simple anvil]

Player p = e.getEntity().getPlayer();
        ItemStack glass = new ItemStack(Material.RED_STAINED_GLASS_PANE);
        e.getDrops().remove(glass);

it is not removeing the glass apon death

How I can update libraries in spigot use BuildTools?

[pliant oyster]

show entire code

[simple anvil]

that is all the code

package HotBarInventory.me.cyberwolfie.Me.Events;

import org.bukkit.Bukkit;
import org.bukkit.Material;
import org.bukkit.entity.Item;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.PlayerDeathEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.ItemMeta;

import java.util.ArrayList;
import java.util.List;
import java.util.Objects;

public class DeathEvent implements Listener {
    @EventHandler
    public void death(PlayerDeathEvent e ){

        Player p = e.getEntity().getPlayer();
        ItemStack glass = new ItemStack(Material.RED_STAINED_GLASS_PANE);
        e.getDrops().remove(glass);

    }


}

[pliant oyster]

does the item even drop?

[simple anvil]

yes

i think its just removing it from the drop list

but idk

[pliant oyster]

oh

[proper notch]

You're trying to remove something you just created, so the drops won't contain that item stack.

[round finch]

probably not the same item

[simple anvil]

oh

so do i need to make a item public?

[proper notch]

You probably want something more like:

for (ItemStack drop : event.getDrops())
  if (drop.getMaterial() == Material.RED_STAINED_GLASS_PANE)
    event.getDrops().remove(drop);```

haven't used spigot in quite a while so that naming might be wrong

[tall dragon]

or List#removeIf 😉

[proper notch]

o yh that's a thing

do that instead ^^

[simple anvil]

?

[tall dragon]

you can use e.getDrops().removeIf()

[round finch]

it is a Item List

[tall dragon]

so?

[round finch]

wait nvm

i thought something else
it was wronng

[faint sage]

🐦

[round finch]

i thought
maybe set Item on Respawn then Die
to test

[simple anvil]

e.getDrops().removeIf(drop -> drop.getType() == Material.RED_STAINED_GLASS_PANE);

this works

[tall dragon]

yea i know.

[round finch]

ofc

 private static ArrayList<ItemStack> Special_Items = new ArrayList<ItemStack>();

  @EventHandler
  public void OnPlayerRespawn(PlayerRespawnEvent e) {
    
  Player p = e.getPlayer();
  
  if(Special_Items.isEmpty()) {
    
  ItemStack Special_Item = new ItemStack(Material.DIAMOND,1);
          
  Special_Items.add(Special_Item);    
  
  }
  
  for(ItemStack item : Special_Items) {
  p.getInventory().addItem(item);  
  }  
  
  
  }
  
  @EventHandler
  public void OnPlayerDeath(PlayerDeathEvent e) {
   
        
  
  for(ItemStack item : Special_Items) {
      
  if(e.getDrops().contains(item)) {
  Bukkit.broadcastMessage("Dont Drop Your Item" + item);
  e.getDrops().remove(item);   
  }      
  
  }         

[hasty prawn]

oh god why

?paste

[round finch]

it was just an Exemple

[tall dragon]

ye dont post big code blocks

Dessie will become unwell :D

[hasty prawn]

[round finch]

oof

[hasty prawn]

Code blocks are fine (sorta), but the initial way you formatted it was...

It's much better now lol

[round finch]

@simple anvil here if you want it

[simple anvil]

it works now

thanks

also

List<Integer> slot = new ArrayList<>();
        int i;
        for (i = 9; i < 36; i++) {
            slot.add(i);
        }

        if (e.getSlot() == slot) {
            e.setCancelled(true);
        }

i wanna make the slots 9-36 all cancel if you click on them

i cant use int with list

and i dont wann have a or statment for all the numbers

imma go eat dinner

bye

[tall dragon]

so guys i have a math question.
i have a list of Materials that each have a certain worth. (these materials are spawned into a generating mine)
now im making minions, and they automatically mine those ores (or at least pretent to) now when i a player opens my menu i need to "simulate" how much that minion has made in the time the player was away. and there are a few factors to take into account. such as efficiency, fortune. does anyone know a good way to go about this?.

My first idea was to calculate how many blocks the minion couldve broken, take the total % chance to get a certain ore and that would be the amount of ores from that type. the problem then is fortune as i probably would have to generate a chance for the amount of blocks the minion had broke. this could be a high number like 1.000.000, that probably would not be very performance friendly, sooo anyone any ideas? let me know.

probably best way to do this if had some formula that can give me the amount of times a chance would return true. with a changing amount & chance

[eternal oxide]

its only math with no in game actions. it doesn;t matter how many blocks

[round finch]

InventoryClickEvent

[tall dragon]

will it be fast enough?

[eternal oxide]

plenty fast enough

[tall dragon]

like generating a random 1mil times for example

[eternal oxide]

you can do all teh calculation async so it won;t matter at all

[tall dragon]

dont know about that, when a player opens my menu. it should be updated then and there

[round finch]

amount of fortune drops

speed of efficiency

time

[tall dragon]

or i could handle that differently?

[eternal oxide]

just calculate at regular intervals, like the minion has to bring the rewards home

[tall dragon]

that would require me to keep the "Mine" object in memory though

[round finch]

config to get it

[tall dragon]

which is something im trying to avoid

[eternal oxide]

mine object?

[tall dragon]

or i would have to read straight from my data file

[eternal oxide]

config should not be used to store player data

[round finch]

it could for numbers

[tall dragon]

worded it badly

[eternal oxide]

as it is player specific data, and only related to a few numbers put it in their pdc

[tall dragon]

its not though
