[solemn meteor]

Oh does it?

so all I need is to make the class TabExecutor and remove the TabCompleter part?

[jagged monolith]

Remove the getCommand("chud").setTabCompleter(new CoordinatesHUDTabExecutor());

[solemn meteor]

alright

[rough drift]

Should I make the tab api synchronized? (only on main thread), or should I just support multiple threads editing it?

i am trying to look send a message in chat when a player breaks a block.

This is the code i wrote so far but it gave me an error when i tried running it on the server.

[small current]

How can i prevent ghost items in my gui

Whenever i click a ghost item appears

[remote swallow]

the ghost items are pretty much all client side so there isnt really much you can do

[small current]

I dont see it always happening in othet gui plugins

[remote swallow]

wheres the ghost item

on the cursor or in the inv

[small current]

In my cursor

[remote swallow]

you could try and set the cursor to null

[small current]

Lemme try

Thanks

It worked

[quaint mantle]

how do i find event function names? like onPlayerJoin() and onBlockBreak()?

[remote swallow]

normally they are called BlockBreakEvent or PlayerJoinEvent

[quaint mantle]

those are the class names though of the event objects.

[remote swallow]

@EventHandler
public void onBlockBreak(BlockBreakEvent event) {
    event.doSomething();
}

that is without registering the listener

[quaint mantle]

so just get rid of 'event' and prefix 'on'?

is that the convention of spigot plugins?

[remote swallow]

onBlockBreak can be anything

thats custom

[quaint mantle]

oh

ok

oh got it!

appreciate the help!

[remote swallow]

the BlockBreakEvent in the parenthesis should be which event you want

[quaint mantle]

Oh ok!

[remote swallow]

also make sure to register your events

[quaint mantle]

yep.

[sage patio]

How i can place a block with face direction?

[jagged monolith]

Most likely using the BlockFace enum

[hushed pawn]

i want to spawn schematic, and than despawn it, did anyone know methods?

[lethal knoll]

Don't you need to use the WorldEdit API for that?

[hushed pawn]

yes

[lethal knoll]

https://madelinemiller.dev/blog/how-to-load-and-save-schematics-with-the-worldedit-api/

[hushed pawn]

there is no info how to despawn

[lethal knoll]

But what you mean with despawn?

[remote swallow]

remove all the blocks?

[lethal knoll]

You should keep track of where you placed hte schematic

And remove the blocks

^^^^

[hushed pawn]

remove all blocks

[remote swallow]

if you already have the schem you could make a copy of it with all air, then just paste that over the old one

[hushed pawn]

im trying

[lethal knoll]

Yes, so just keep track of the 2 corner locations

[remote swallow]

otherwise you would have to work out a bounding box

[lethal knoll]

What is the part you're strugling with?

[hushed pawn]

i dont even understand how worldedit spawn it

[lethal knoll]

Follow the tutorial

https://madelinemiller.dev/blog/how-to-load-and-save-schematics-with-the-worldedit-api/

[hushed pawn]

SchematicFormat.getFormat(schematic).load(schematic).paste(session, new Vector(0, 200, 0), false);

i do that thing but how to get corners?

[lethal knoll]

Not too sure, you might have to iterate over all the blocks in the clipboard and fetch the corners yourelf

Okay, so let me ask the all knowing AI lol

// Load the schematic from file
File schematicFile = new File("path/to/schematic.schematic");
Schematic schematic = MCEditSchematicFormat.getFormat(schematicFile).load(schematicFile);

// Paste the schematic at the specified location with the `false` option set
EditSession editSession = WorldEdit.getInstance().getEditSessionFactory().getEditSession(world, -1);
WorldEdit.getInstance().getPasteFactory().createPaste(schematic).to(editSession, new Vector(x, y, z)).ignoreAirBlocks(false).paste(false);

so by setting false, it would remove it again the AI say's

not too sure if this is reliable

so I ssume that x y z represents the exact location of where the schematic was pasted

then WE does the rest for you

[hushed pawn]

i already tried, problem is that i use Worldedit 6 version

[lethal knoll]

// Load the schematic from file
File schematicFile = new File("path/to/schematic.schematic");
Schematic schematic = MCEditSchematicFormat.getFormat(schematicFile).load(schematicFile);

// Paste the schematic at the specified location
EditSession editSession = WorldEdit.getInstance().getEditSessionFactory().getEditSession(world, -1);
WorldEdit.getInstance().getPasteFactory().createPaste(schematic).to(editSession, new Vector(x, y, z)).ignoreAirBlocks(false).paste(true);

// Remove the schematic from the world
editSession.remove(schematic.getRegion());

Spigot Server Build Failure

[small thistle]

Hi, would a kind soul be able to point me in the right direction on where to begin with adding a permission to craft my custom item?

The results that I'm finding are from 2015 or earlier and seem to be outdated. Thanks in advance

[vague swallow]

check if the player has the permission if(player.hasPermission("your.permission.path"))

and then log the permission in the plugin.yml

permissions:
  your.permission.path:
    default: op

[small thistle]

Apologies, I meant using a permission check upon the crafting of the item

something like if (recipe === custom item) check for permission permission.example then allow or disallow based on permission

I'm currently looking at the event.getRecipe() but I think this is the wrong one

[sage patio]

How i can set block face to south or smth else in 1.12.2?

[opal juniper]

use the Rotatable Interface

[sage patio]

what is that

[undone yarrow]

Is it possible to change a mobs behaviour, or perhaps even add custom behaviour to a model/armorstand (such as a custom mob following you around and it attacking specified mobs. Basically a wolf but with more custom behaviour)?

[quaint mantle]

hi

how do i iterate through all 16 colors of wool blocks?

i am trying to make an array of blocks with all 16 colors of wool.

how can i do it?

[undone yarrow]

Ever heard of for loops?

[quaint mantle]

i know that

but how do i generate the array?

instead of manually typing out each color?

anyway to iterate all colors?

[undone yarrow]

Hmm good question. In this case I think it'd be easier to just type it out 🤷‍♂️

there are only 16

[quaint mantle]

ok.

[undone yarrow]

it might be possible though, but not that I know of

[undone yarrow]

https://www.spigotmc.org/threads/loop-through-all-possible-blocks-in-minecraft.223157/ This might be of help

[quaint mantle]

also

the Material class represents the type of item a block is, right?

like wheat_seeds or diamond swords or grass blocks, right?

if i got that correctly?

[tardy delta]

ye

[dry yacht]

What version are you on?

[tardy delta]

do you have java experience?

[quaint mantle]

i know java, yep.

i making a 1.19.2 plugin.

[undone yarrow]

Coming back to this, all I want to do (for now) is make a wolf run away when it's low health. I found the function called .setTarget. Would it possible to set the target of the wolf to the player when it's low health, so that it runs away from the enemy?

[quaint mantle]

i am making a small minigame.

[vague swallow]

This will prolly help you: https://www.youtube.com/watch?v=e55PHe3hiuY

[tardy delta]

just make a list with all of the wool colors in

Arrays.asList like

[dry yacht]

for (Material mat : Tag.WOOL.getValues()) { }

Then this should be available to you, try it please.

[tardy delta]

or that, didnt even know wool had a tag too

kinda stupid that specific tools dont have a separate tag too

[dry yacht]

Well, where would you draw the line? There are an infinite amount of tags you can create, based on all kind of needs. I'm already happy that this concise list of Tags is being maintained.

[sage patio]

ow codedred

i learned coding spigot from that guy

[quaint mantle]

oof, i already typed them all out lmao

[vague swallow]

yeah he's one of the best

[sage patio]

he's the best* (for me)

[vague swallow]

agreed

[quaint mantle]

how does spigot run on paper?

[undone yarrow]

Damn, that's sicks. Thanks!

[vague swallow]

giv incoming

[quaint mantle]

by that i mean, how well does spigot run on paper?

[vague swallow]

all spigot plugins I tried on paper worked perfectly

[quaint mantle]

ok

[dry yacht]

I'd still advise you to use my solution, as you thus don't have to maintain this manual list. What if a new version adds a new color block? :)

[tardy delta]

paper is a fork of spigot so all spigot plugins should work on paper

[quaint mantle]

hm, okay then!

[tardy delta]

ah floating point division

[humble tulip]

000000000001

[tardy delta]

when using a float as divider it only becomes worse: 0.12300000106915832

could also use a double but then i have overflow after around 10 digits behind the comma

[humble tulip]

Can i see current()?

[dry yacht]

Damn dude, what java version is that?

[tardy delta]

17

[dry yacht]

That loop label got me good, haha

[tardy delta]

otherwise it breaks the switch and not the loop so cant do anything else

[dry yacht]

Of course, I just didn't know that was a thing.

[dry yacht]

Could've just returned result tho

[tardy delta]

ok thought i'd have overflow but no

[subtle folio]

what is your theme?

[tardy delta]

one dark

[subtle folio]

ew

[humble tulip]

This seems lile it's easier to just convert to a charsrquence, put a 0. To the start and parse a double

[tardy delta]

then dont ask it

[subtle folio]

haha

[round finch]

*asked

[humble tulip]

Did you compare times between those?

[tardy delta]

Double.parseDouble is slow

[dry yacht]

Halcyon is better.

[undone yarrow]

Why does this not work?```
@EventHandler
public void onXPBottleBreak(ExpBottleEvent event){
Block block = event.getHitBlock();
block.breakNaturally();

}``` event.getHitBlock() always returns null (it also didn't work in the tutorial)

[tardy delta]

and it tests for a bunch of things like NaN which i dont need

[subtle folio]

i have nothing against it

[humble tulip]

Did you compare to your method?

Ah ok

[quaint mantle]

Null check it?

[tardy delta]

ye i did, forgot how much slower it is actually

[undone yarrow]

I can check for a null but I know it returns null

[hushed pawn]

why worldEdit spawn schematics witch are exact same size with the same code in 2 different places?

SchematicFormat.getFormat(schematic).load(schematic).paste(session, new Vector(20, 64, 0), false);

[quaint mantle]

You need to null check it

return if null

[undone yarrow]

how will that solve the issue

it will just prevent it from giving an error

[tardy delta]

all parser i tested seem to have the same rounding issues

[undone yarrow]

but it won't fix the thing will i

[chrome beacon]

Why would there be two different sizes?

[round finch]

if it doesn't return null everytime
null check is the option

[dry yacht]

Guess why...

[tardy delta]

6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4 + 6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4 + 6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4 + 6.5*7.8^2.3 + (3.5^3+7/2)^3 -(5*4/(2-3))*4 guess why

[quaint mantle]

You need to null check

[dry yacht]

Has nothing to do with the parser, at all.

[undone yarrow]

fine

[hushed pawn]

i do that code for 2 same sized schematics

[tardy delta]

ye ik it just sucks

[quaint mantle]

Idk what you're trying to achieve but you always have to null check something that can be null, that's how it works lol

[undone yarrow]

Like this? public void onXPBottleBreak(ExpBottleEvent event){ if(event.getHitBlock() == null) return; Block block = event.getHitBlock(); block.breakNaturally();

[chrome beacon]

So what's the problem

If you spawn two of the same sized structures with the same code and they're the same size

then there is no problem

[tardy delta]

Optional.ofNullable(event.getHitBlock()).ifPresent(Block::breakNaturally) :)

[undone yarrow]

what the heck is that

[tardy delta]

the short and weird way

[undone yarrow]

Can you explain what it is?

[chrome beacon]

I got you covered: https://www.youtube.com/watch?v=vKVzRbsMnTQ

[hushed pawn]

i thought one will replase another, but they spawn like with 3 blocks offset

[tardy delta]

wraps a nullable thing and executes a consumer when its present lol

[undone yarrow]

right...

[dry yacht]

Noooo, don't create a new object to abstract the null check away, this is insanity!

[quaint mantle]

oooh

[tardy delta]

lemme guess that jit will optimize it

[hushed pawn]

   static public void spawnFinish(Location loc) {
        try {
            EditSession session = worldEdit.getWorldEdit().getEditSessionFactory().getEditSession(new BukkitWorld(Bukkit.getWorld("world")), 999999);
            File schematic = new File("plugins/WorldEdit/schematics/finish.schem");
            SchematicFormat.getFormat(schematic).load(schematic).paste(session, new Vector(20, 64, 0), false);


        } catch (DataException | IOException | MaxChangedBlocksException e) {
            throw new RuntimeException(e);
        }
    }

    static public void despawnFinish() {
        try {
            EditSession session = worldEdit.getWorldEdit().getEditSessionFactory().getEditSession(new BukkitWorld(Bukkit.getWorld("world")), 999999);
            File schematic = new File("plugins/WorldEdit/schematics/voidfinish.schem");
            SchematicFormat.getFormat(schematic).load(schematic).paste(session, new Vector(20, 64, 0), false);
        } catch (DataException | IOException | MaxChangedBlocksException e) {
            throw new RuntimeException(e);
        }
    }

[tardy delta]

whatever, thre are people who code like that

[dry yacht]

Who's jit?

[tardy delta]

just in time compiler

glad you didnt ask 'whos joe'

[hushed pawn]

bru

[chrome beacon]

Make sure you don't have an offset in the schematic

Schematics save the relative position where you are when creating them

[undone yarrow]

So what should I do?

[chrome beacon]

A normal if statement

[hushed pawn]

relative to what?

[chrome beacon]

To the schematic

[dry yacht]

You meant by the bytecode runtime? Sorry, but JIT was a bit vague for me.

[dry yacht]

if (value != null) value.doSomething()

[chrome beacon]

0, 0, 0 in a schematic is one of the corners

[tardy delta]

well it optimizes the performance of an application by compiling hot java bytecode

hot meaning thats its called often enough or smth

[dry yacht]

Ah, you mean the "JIT optimizer", so to say. Alrighty. But still, it first has to get hot. Why make it hot, if you can just do != null. I think that's just wrong.

[tardy delta]

probably 2nd time it runs it will be considered hot

got the same thing for my parser

a simple '1+1' executes in 12000µs without taking jit into account, second time that becomes a magically 30µs or smth

[undone yarrow]

Can I also just return null?

[dry yacht]

Are we really starting to get into the age of brainless coding because our machines get smarter than the average programmer? Ouch.

[quaint mantle]

Yeah just say if its null return;

[chrome beacon]

You can't return null if the return type is void

[dry yacht]

I don't know what your code looks like, you could show me the troubling method and I can give you a specific answer.

[chrome beacon]

Just keep that in mind

[undone yarrow]

@EventHandler
public void onXPBottleBreak(ExpBottleEvent event){
if(event.getHitBlock() == null) return ;
Block block = event.getHitBlock();
block.breakNaturally();

}

[tardy delta]

ok not 12000 but whatever :)

[dry yacht]

Right, that works out, doesn't it?

[quaint mantle]

Yeah that's fine

[undone yarrow]

k

[rotund ravine]

@EventHandler
    public void onXPBottleBreak(ExpBottleEvent event){
        Block hitBlock = event.getHitBlock();
        if(hitBlock == null) return;
        hitBlock.breakNaturally();
    }

[chrome beacon]

Change that last block to hitBlock

[rotund ravine]

I did haha, no proof

[jade roost]

how do i give items to player on join?

[quaint mantle]

PlayerJoinEvent

[rotund ravine]

What he said

[hushed pawn]

i just save schematic, than do //set 0, than save another one
so i hoped one will clear another
but it spawns with few blocks offset

[dry yacht]

By subscribing to PlayerJoinEvent and calling player.getInventory().addItem()

[jade roost]

alr

[quaint mantle]

Is subscription expensive?

[rotund ravine]

the first time it can be

[quaint mantle]

Damn

Money grabbers man

[undone yarrow]

only 5$ a month

[rotund ravine]

I paid some onlyfans chick and she didn't even pose without bikini. Very dissapointed.

[undone yarrow]

...

[quaint mantle]

What a bitch

[dry yacht]

Very expensive, you have to go through a whole bunch of bad-code-writers before you can let that packet finally do it's job, because they all subscribed to the event.

[undone yarrow]

why tf would you pay for onlyfans if it's leaked and free

[tulip drift]

Hello, no matter how hard I try I cannot use craftbukkit dependency. I have run buildtools and it has generated the jars.
I am using maven for my dependencies. Even when i add the craftbukkit dependency manually as a jar with systempath it still doesn't allow me to import anything from craftbukkit.

Does anyone know how to help me?

[chrome beacon]

Don't depend on CraftBukkit

[dry yacht]

Why would you ever rely on that tho.

[quaint mantle]

Yeah use spigot

[rotund ravine]

it wasn't leaked.

[chrome beacon]

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[chrome beacon]

Also this ^^

[tulip drift]

I should have mentioned im using 1.8.8, and I need craftplayer to try and remove arrows stuck inside players

[drowsy helm]

optionals are hella overrated

[undone yarrow]

Well no errors, but it still doesnt fix my issue of it not breaking the blocks

[dry yacht]

Are you sure you're importing from your local maven repo? Have you got any references to the spigot repo?

[chrome beacon]

True. I never use them

[quaint mantle]

I swear you're using expevent? What you trying to achieve?

[undone yarrow]

break the block which the expbottle hit

[dry yacht]

Does it work?

[undone yarrow]

...

[quaint mantle]

Why you using expevent then? Or am i tripping

[tulip drift]

need help importing craftbukkit using maven dependencies 1.8.8 (sending again to create a thread)

[undone yarrow]

Because I want to break the block which the bottle hit when the bottle breaks

[quaint mantle]

ohh i see

Send code again

[dry yacht]

?

[chrome beacon]

@dry yacht

[quaint mantle]

how do i get the overworld dimension?

[dry yacht]

Right, thanks, I'm just all over the place again.

[quaint mantle]

World overworld = getServer().getWorld("overworld");
is this going to work?

whats your world called

[chrome beacon]

if you have a world named overworld yes

[quaint mantle]

"world" probs

[chrome beacon]

Otherwise no

[quaint mantle]

i need the overworld.

[tardy delta]

Bukkit.getWorlds().get(0)

[quaint mantle]

yes whats it called

[tardy delta]

0 is always overworld, 1 is nether and 2 is end and all others are custom worlds

[quaint mantle]

the world folder is named "world".

[chrome beacon]

It's called world by default

then use getWorld("world")

[quaint mantle]

oh ok

then put world in the string args

okay.

[undone yarrow]

@EventHandler
public void onXPBottleBreak(ExpBottleEvent event){
if(event.getHitBlock() == null) return ;
Block block = event.getHitBlock();
block.breakNaturally();

}

[quaint mantle]

Any new errors?

World overworld = getServer().getWorld("world").get(0);

[undone yarrow]

no

[quaint mantle]

you don't need .get

the get() method is red.

[chrome beacon]

No

[quaint mantle]

oh ok.

[chrome beacon]

Don't combine the two

[tardy delta]

Bukkit.getWorlds().get(0), Bukkit.getWorlds() returns a list of all worlds on the server

get(0) gets the first one remember

[quaint mantle]

have you debugged does it get stuck anywhere

oh ok.

[undone yarrow]

It just returns null each time

that's the issue

event.getHitBlock()

it just returns null

every single time

[quaint mantle]

put null check after the block variable declaration and check if block == null

[tardy delta]

testing smth new is always fun

[quaint mantle]

How do you know its returning null did you debug?

[undone yarrow]

I-...

I'm just going to go

[dry yacht]

Wait, I'll send you a solution in a second

proguard just eliminated my events as unused code and I was wondering why the heck nothing works, damn dude

need a better conf

[remote swallow]

i would say theres something up with your server jar

been as yesterday using player#damage would crash the server then this

[dry yacht]

Why the hell can't i paste code into the chat bar without it being ruined... Stupid ass app.

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

[dry yacht]

That's legit all you need to accomplish your goal

[chrome beacon]

That won't drop items

[quaint mantle]

He wants natural drop

[dry yacht]

Oh, didn't read that

[chrome beacon]

Depends on what your goal is with that task

[dry yacht]

Well, not that hard either once you got the right event

[quaint mantle]

I think he gave up anyway

rip

[chrome beacon]

Then onEnable is fine

[dry yacht]

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

[undone yarrow]

Ill give it a test

[undone yarrow]

Seems to work. Now I'm just wondering why the previous code didn't work

[quaint mantle]

The event probs

[dry yacht]

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

Block can be null, added a check, please update the code.

[dry yacht]

Good question tbh

[undone yarrow]

you just made the code 3x as long by adding a null check?

[dry yacht]

?

[chrome beacon]

Personally I think the block is just null so the code isn't running

[dry yacht]

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

Btw, no need to drop the item manually, I'm not familiar with these APIs.

[chrome beacon]

I've seen you discuses this for a while now but you haven't actually checked if it passes the null check

[dry yacht]

You're right: logged: ExpBottleEvent.hitBlock=null

[dry yacht]

Btw, thanks for being that appreciative, :).

[dry yacht]

Why even have the property then?

[undone yarrow]

Sorry, didn't mean to come over that way. I was just a bit pissed because everyone asked the same question 10 times over. Thanks for helping, I appreciate it a lot 🙂 I'll share the code in the comments of the video (the dude who made the vid also wasnt able to get it working)

[chrome beacon]

Sounds like a Spigot bug if it's always null

?jira You can report it here

[undone axle]

https://hub.spigotmc.org/jira/secure/Dashboard.jspa

[dry yacht]

It depends on whether you want to drop the block type or the actual material you'd get when mining it which dictates whether breakNaturally or dropItemNaturally is to be preferred. Otherwise, I think the ProjectileHitEvent is the only solution, as the ExpBottleEvent never provides you with an actual target block value.

[undone yarrow]

I can but will they fix bugs from a previous version? Won't they just continue fixing bugs for only the current versions?

[chrome beacon]

ExpBottleEvent extends ProjectileHitEvent

So it would supprise me if the event fired is the same instance passed to different listeners

[dry yacht]

I asked that often because this chat is way too active and I'm working on a project on the side, so I missed a lot.

[chrome beacon]

Then it's simple fix it yourself or update

[undone yarrow]

Well I wasn't talking about just you lol. But I get it, the chat can get cluttered

[dry yacht]

Here's your reason

The API's confusing as hell tbh.

So this is intended, don't file anything, btw.

[chrome beacon]

It's still an improvement you can still create an issue

or make a PR

[undone yarrow]

I don't get it

[chrome beacon]

It's always null in the spigot code

[dry yacht]

When they call the event in CraftBukkit, they use the constructor (ThrownExpBottle, int), which internally calles the super-constructor of the ProjectileLaunchEvent, as every ExpBottleEvent is a ProjectileLaunchEvent, because it inherits from it. But that super constructor invokes a constructor of the ProjectileHitEvent where the block as well as the thrower have null as their default values.

[undone yarrow]

ahh alright

[tardy delta]

why cant java do defaults args like in kotlin or c++ smh

[dry yacht]

I think the information should be available, if the NMS MovingObjectPosition represents the position when hitting, which this would kind of suggest.

No idea why you wouldn't call the event with it. Seems like a weird decision to me.

[chrome beacon]

That's not Mojmaps

[dry yacht]

Who cares about mappings?

[chrome beacon]

It's called HitResult in Mojmaps

So yes that appears to be the information required

[ivory sleet]

Mojmaps are nice tho

[dry yacht]

I just grep -rni around within the build tools folder, not really thinking much about anything, just want to get my information.

[chrome beacon]

If making a PR was easier I would have fixed that

Doesn't seem like a hard thing to fix

Yes, use the spawn method that takes a consumer

(modify the armor stand in the consumer)

[spice shoal]

?

[undone yarrow]

?

[vague swallow]

Does anyone know why this:

player.addPotionEffect(new PotionEffect(PotionEffectType.WITHER, 2, 3, true, false, false));

adds the effect but doesn't damage the player?

[fluid river]

is wither supposed to damage player

oh true

[undone yarrow]

Wither: "
Deals damage to an entity over time and gives the health to the shooter."

[dry yacht]

Does the player have the effect? That's a short ass duration tbh

[chrome beacon]

That duration is 2 ticks, not enough to damage the player

[undone yarrow]

oh right thats it

[dry yacht]

Yep, it's in ticks, so at least a multiple of 20 i'd say, for you to see it

[undone yarrow]

duration is in ticks, not seconds

[fluid river]

ticksamount

[undone yarrow]

But usually wither is given to a player by a different entity (or the other way around) so now there's no entity to gain the health taken away from the player

perhaps that can cause problems, but Im not sure

cant we just make a thread for it

#spigotcraft isn't really the right channel either is it

[ivory sleet]

Dont think the bot works in threads

[undone yarrow]

lets try

[tardy delta]

no

[ivory sleet]

Yes, but its better than doing it here

[remote swallow]

spigotcraft is just our shitposting channel

k it doesnt work in trheads

[humble tulip]

Is there anyway to send a bytebuf as a packet?

[undone yarrow]

lol

[vague swallow]

yeah thanks

[undone yarrow]

cc list command doesnt work in other channels tho

[ivory sleet]

Its not supposed to work here also afaik

[dry yacht]

Not sure what you mean. A packet by definition has to travel across the network, so you can only send bytes. It would be best to destruct the ByteBuf into it's real byte[] before sending and reconstructing it at the receiver's endpoint. If you're talking about the client, there's a plugin message packet which offers you a way to transmit raw bytes.

[undone yarrow]

?cc list

oh

it only works in #bot-commands

[quaint mantle]

[humble tulip]

I'll explain in a bit

[dry yacht]

Command not registered in plugin.yml

[humble tulip]

Make sure the command is in your plugin.yml

[quaint mantle]

oh ok.

where is plugin.yml?

[chrome beacon]

Depends on how your project is setup

[quaint mantle]

its running a paper server.

[dry yacht]

in your resources folder

[chrome beacon]

Since you don't know where it is I assume you used the Minecraft Development Plugin for Intellij to create your project

[remote swallow]

server type doesnt mean project setup

[quaint mantle]

Anyone know how to get working placeholders on your own scoreboard? I parse them in game and they work but on my scoreboard they don't?

[chrome beacon]

so this

[chrome beacon]

Show your code

[chrome beacon]

?paste

[undone axle]

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

[quaint mantle]

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

[dry yacht]

Do you mean PAPI placeholders on your own, custom written scoreboard? Or is it a public scoreboard plugin?

[quaint mantle]

My own scoreboard

commands:
  blockparty:
    description: Creates a block party game.
    usage: /<command>
    permission: FirstPlugin.operator```

is this looking right?

[chrome beacon]

Show your CC class

[quaint mantle]

That's just colour converter

[dry yacht]

You need to call placeholderAPI to substitute values in, how else would it know about your code.

[quaint mantle]

i am trying to make it so that only a player with /op can run the command

[quaint mantle]

I've never done papi with my own scoreboard so no idea.

[humble tulip]

All packetplayoutblabla instances have a method that accepts PacketDataSerializer and writes the contents of the packet to a bytebuf.

[quaint mantle]

um

[chrome beacon]

So you have no placeholders?

[ivory sleet]

You have to define the defaultness of the permission

[quaint mantle]

did i get the thing above correct?

[chrome beacon]

ofc it isn't working

[quaint mantle]

Yes I do

[remote swallow]

https://github.com/PlaceholderAPI/PlaceholderAPI/wiki/Hook-into-PlaceholderAPI

[quaint mantle]

I have placeholders...

[humble tulip]

I'd like to send a packet that i wrote without having to turn it back into a packetplayout

[quaint mantle]

.

[remote swallow]

you need to use PlaceholderAPI.setPlaceholders

[quaint mantle]

They work in game when i /papi parse me

[quaint mantle]

um, could you elaborate more?

[chrome beacon]

Not in the code you've sent

[remote swallow]

you just use CC.translate

[quaint mantle]

I have a seperate class for them of course

[chrome beacon]

Anyways use this

[quaint mantle]

Okay so i need to set as placeholder

Will do

[chrome beacon]

PlaceholderAPI won't magically change strings for you

[quaint mantle]

should it be /<command> or do i have to put the command name there?

[ivory sleet]

In ur plugin.yml

permissions:
  firstplugin.operator:
    default: op

[chrome beacon]

You need to tell it to replace placeholders

[quaint mantle]

oh ok!

[ivory sleet]

basically saying, this permission will be by default inherited to all OP players

[dry yacht]

Just add papi to your dependency list and call this method. Also, add a depends entry to your plugin.yml

[quaint mantle]

permissions:
  firstplugin.operator:
    default: op

commands:
  blockparty:
    description: Creates a block party game.
    usage: /<command>
    permission: firstplugin.operator```

[dry yacht]

So you're writing a custom client?

[humble tulip]

Nah

[quaint mantle]

should the usage be /<command> or /blockparty>?

[humble tulip]

Just wanted to know if it's possible

[remote swallow]

<command> just shows the command

[quaint mantle]

Do I do this in papi class where I created the placeholders or in scoreboard class?

okay

[chrome beacon]

You need to replace the placeholders in the string just like you need to replace the colors

[quaint mantle]

kk

[dry yacht]

What are you trying to achieve then

[quaint mantle]

um

[humble tulip]

Send a packet but without creating a packet object

[quaint mantle]

i am still getting an error.

[chrome beacon]

You will need an object. You can use reflection to create said object

[humble tulip]

I know

I want to write the packet myself

[dry yacht]

io.netty Channel#writeAndFlush can write Objects, you'd need to inject the player using my code to gain this type of direct access. But again, you need to modify the client or it'll either crash or drop the packet.

[tardy delta]

ah right you cant extend records \😢

[humble tulip]

To a bytebuf

[humble tulip]

And send it

[chrome beacon]

So you're making custom packets?

[dry yacht]

Please use pastes

[humble tulip]

Nope regular packets

[dry yacht]

.

[chrome beacon]

What's the point of rewriting them?

[quaint mantle]

um, what?

[dry yacht]

?paste

[humble tulip]

The chunk packet

[quaint mantle]

?paste

[undone axle]

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

[dry yacht]

You just spammed away my message with your mile long stacktrace, haha :,D.

This is why pastes are preferred.

[quaint mantle]

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

[quaint mantle]

sorry!

[humble tulip]

I'd like to send modified chunks to certain players by sending a chunk packet

[chrome beacon]

So use the vanilla one

[humble tulip]

But using mc to send a chunk packet is slow

[remote swallow]

does the plugin.yml actually get added to the jar, use 7zip or winrar to check

[dry yacht]

All good, just wanted you to understand the reason of pastes, rather than to just tell you to use them.

[chrome beacon]

Your chunk packet isn't going to be faster

You will still need to follow the exact same format containing the same information

and the client will process it in the same way

[humble tulip]

Lol yes but i won't have a lock on the palette

To modify it

[tardy delta]

nah records are final classes, forgot that

its stupid

[quaint mantle]

everytime i compile, the contents of plugin.yml seem to get deleted.

[humble tulip]

The problem is modifying the chunksection is slow

Not writing the packet

[chrome beacon]

How are how changing the plugin.yml

And what plugin.yml are you changing

[quaint mantle]

the one in the resources folder

[tardy delta]

how does it make sense, immutable data carier ok i understand that

[quaint mantle]

OH

i was using the one in the orange resources folder lol!

[chrome beacon]

ah yeah that's the wrong one

The target folder is the output from when your plugin is built

[quaint mantle]

yay, the command works!

[dry yacht]

How are you gonna modify it tho? Intercept real chunk packets and then create your own carbon copy and modify that? This effectively duplicates the memory burden and also takes some time.

[ivory sleet]

Non final makes it non transparent

Fourteen, don’t forget that they’re not only immutable data carrier, but also transparent

[subtle folio]

Can I use spring boot in a spigot plug-in ?

[chrome beacon]

Yes ofc

[subtle folio]

To host a rest api

[chrome beacon]

Yes you can do that

[tardy delta]

wdym by transparant

[chrome beacon]

If you just want a rest api try Javalin

[tardy delta]

they should make record classes to avoid writing a bunch of fields and getters

meanwhile lombok 😬

[subtle folio]

Never heard of it, can you link me it?

[chrome beacon]

https://javalin.io/

[ivory sleet]

Not only that

[subtle folio]

yeah no not for me

I use JPA

never will i ever 😂

even rust is better than go

[ivory sleet]

Just read the jep fourteen

That says everything

[tardy delta]

mmmh

[ivory sleet]

Well sort of zacken

[tardy delta]

which one tho

[ivory sleet]

395

In this case transparency as in that for all terms X of record type T, all fields are known for X

If we suppose T is non final, a subtype S could presumably add additional fields

And that’d remove the transparency

[tardy delta]

got it, its still annoying tho

[ivory sleet]

So you’re gonna become a lomboker?

[tardy delta]

i dont dare

[ivory sleet]

🥲

[tardy delta]

ill see

[chrome beacon]

Lombok is fine tbh

[dry yacht]

I'm a proud lomboker

[tardy delta]

probably in the future

[ivory sleet]

Mye, just dont find its usefulness personally

[tardy delta]

annotations just look brr

[chrome beacon]

I usually use @Data

[ivory sleet]

Ah

[chrome beacon]

Basically a record thing

but for older java

[tardy delta]

i always find it confusing when you find just a few annotations instead of a class' impl

[ivory sleet]

Yeah, sounds like kotlin data classes

[chrome beacon]

I've also used @Delegate

[rotund ravine]

exactly like them

[tardy delta]

that comes in handy

[rotund ravine]

lombok is the poor mans kotlin

[ivory sleet]

Oo right

[tardy delta]

is there a way to specify what methods to delegate or does it just delegate everything?

[remote swallow]

does anyone use intellij on linux and know if i can access other storage devices in the file browser thingy

[ivory sleet]

Kotlin + lombok must be a death sin then

[tardy delta]

wdym file browser thingie

[chrome beacon]

You give it a class or interface to delegate

[remote swallow]

this

i cant access the other partition on my ssd or my other hdd

[rotund ravine]

i think lombok will just spass out

since kotlin already does everything lombok does

[tardy delta]

maybe try pasting it the path in the box above?

[remote swallow]

idk what its location would e

be

[chrome beacon]

I don't use it very often either

Just when I really need it

I usually write my own getters and setters

[tardy delta]

@remote swallow you can

accessing my windows ssd

just do /media

[remote swallow]

ah its /media

thanks

[tardy delta]

ye i was thinkign about /dev/sda whatever too

[remote swallow]

do you ever just open all of your intellij projects at once to have them available to use

[tardy delta]

no

i have 2 projects open at most

[ivory sleet]

I did once but my pc crashed so never doing it again

[remote swallow]

im most likely never gonna use them all at once or most again

i just like having them there

so incanse i need them

[remote swallow]

how many projects do you have, damn

[ivory sleet]

It was maybe 10 or less

[tardy delta]

my pc once crashed when i opened a txt file optic sent me with a few thousand lines and it tried rendering it 🤔

[remote swallow]

you what

[ivory sleet]

But yeah, that was a year ago

IntelliJ is probably more optimized now

[remote swallow]

ive just opened 43 projects

and my computer is fine

it seems

[tardy delta]

just why

[ivory sleet]

Yeah lol

[remote swallow]

so i can open them if i need them in the future

[hushed pawn]

why i set this block as vector, but schematica spawned like this?
https://imgur.com/a/ikg0CLf

[remote swallow]

might need code out of them

[tardy delta]

bruh just open them when you need them

[ivory sleet]

Just have it on github?

And browse the code there

[tardy delta]

or open the whole project structure on vsc

ya

[remote swallow]

but that means having to find them

[tardy delta]

💀

[remote swallow]

also takes too much effort to upload them all

[ivory sleet]

Lol

[ivory sleet]

It takes like 3 seconds

[remote swallow]

i could upload the entire folder but meh

[tardy delta]

you cant be a git noob for that

[ivory sleet]

Well, you are a developer so I assume laziness is prevalent in you

[remote swallow]

if you ask me to code something thats fun ill do it in an hour

[tardy delta]

imagine having discipline

[remote swallow]

everything else i need atleast 4 working days

[tardy delta]

i got out of my bed at 11am this morning

[ivory sleet]

Havent for some months

But used to swim, and go to the gym

18 now

[tardy delta]

:o

didnt know we were the same age

[ivory sleet]

Yea

Gymnasium?

Teknik

Or like technology whatever

Ye

Epic

Ah

[chrome beacon]

Nice

[quaint mantle]

games.put(name, new BlockParty(x, y, z, length, width, sender.getServer().getWorld("world")));

public static HashMap<String, BlockParty> games;

[tardy delta]

whats with the world

[compact haven]

why this so true tho

[ivory sleet]

This static variable is null

Or well it points to null

So using any method on it, games.someMethod() results in an exception

You’d have to assign it to some value, probably a HashMap

[compact haven]

mfw they only post code but no error

[tardy delta]

exposing maps hehe

[chrome beacon]

or problem

[compact haven]

and also explicit typing of HashMap

:(

[tardy delta]

and static abuse

basically my first plugin

[compact haven]

🤣 so true

[grand magnet]

I have a question. Why is the player name not displayed in the desired color in the tablist? This is my code

[compact haven]

why do I feel like there’s a better way to do that

oh that’s because there is :C

[tardy delta]

💀

[rotund ravine]

Omg waht the fuck

[tardy delta]

oh i remember again, my first plugin was an ode to static abuse

[compact haven]

mate hasn’t learnt about lists or arrays yet

it’s like so funny in my hs coding classes how they teach stuff like that late

and you end up seeing like 20 variables each numbered

[tardy delta]

oh we learnt about arrays like 4 weeks ago in college 💀

we learnt the arraylist before

[compact haven]

they taught lists before arrays?

💀 in Java?

[tardy delta]

arraylist ye

[compact haven]

that’s just too funny

[tardy delta]

it was so stupid, using lists where a map should be used

[compact haven]

mfw arraylist is just an expanding array

[grand magnet]

Can someone help me?

[tardy delta]

no

?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!

[compact haven]

oh fourteen

he did ask

we just mocked him first

[tardy delta]

If you have a question, please just ask it.

hmm

[compact haven]

he’s the scoreboard dude

with the 14 copies

[chrome beacon]

Error handling was the last part of our school Java course

[compact haven]

instead of a list and loop

[tardy delta]

ah wait he asked first and then asked if someone could help

[dry yacht]

Have you tried to print some debug messages to for example check what the value of your team string actually is, and if the code even executed?

[tardy delta]

maybe try creating a method dude

[chrome beacon]

They even taught basic Swing before learning how to read and handle stacktraces

[tardy delta]

whats spring

[chrome beacon]

mb

Spring is for web stuff

I meant Swing

[compact haven]

honestly I can’t with coding classes, that’s such a problem

how do you teach a library before the actual language

[tardy delta]

ah in the beginning of the year they showed us some graphical stuff and then said oh we arent gonna tackle that this year 💀

[chrome beacon]

I'm not sure if anyone actually understood how the stacktraces work

[tardy delta]

a few people of my class cant even properly write a class

and im just bored in class

[dry yacht]

I'm sure they get plenty of occasions to study them in their natural habitat, lol.

[compact haven]

I’ll be going into ap csa next year (Java class)

can’t wait to see how that’s taught 😏

[tardy delta]

lol

[chrome beacon]

The course is already over

[dry yacht]

Yeah, but the stacktraces are gonna haunt them at home if they'll ever code again.

[chrome beacon]

A few of us started web dev and they're completely lost with js

It's back to the basics

[compact haven]

tbf I can only imagine what Swing stacktraces look like

probably a shit ton of internal methods

[fluid river]

dis is disgustin'

[compact haven]

correct

[dry yacht]

https://github.com/EsotericSoftware/reflectasm

Wait, this only works for public members?

That would suck, actually

[chrome beacon]

Well if you're generating actual code you can't bypass that

So normal reflection is required

[hearty wedge]

Here is my code in spigot 1.16.5 :

package best.lahuiss.linkedinventory.listeners;

import org.bukkit.Bukkit;
import org.bukkit.OfflinePlayer;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerPickupItemEvent;
import org.bukkit.inventory.Inventory;
import org.bukkit.scoreboard.Team;

import java.util.Set;
import java.util.UUID;

public class InventoryListener implements Listener {
    private void syncInventories(UUID id, Set<OfflinePlayer> targetPlayers) {
        Player initPlayer = Bukkit.getPlayer(id);
        Inventory inv = initPlayer.getInventory();
        for(OfflinePlayer player : targetPlayers){
            initPlayer.updateInventory();
            //Bukkit.getServer().broadcastMessage(initPlayer.getInventory().getContents().toString());
            Player p = (Player) player;

            p.getInventory().setContents(initPlayer.getInventory().getContents());
        }
    }
    @EventHandler
    public void onItemPickup(PlayerPickupItemEvent e){
        Player p = (Player) e.getPlayer();
        p.updateInventory();
        UUID uuid = p.getUniqueId();
        Bukkit.getPlayer(uuid);

        Team team = Bukkit.getScoreboardManager().getMainScoreboard().getTeam("bleus");
        Set<OfflinePlayer> players = team.getPlayers();

        syncInventories(uuid,players);
    }
}

It's sensed to be a listener that listens to every change in an inventory and sets the content of the inventory to every people in the team "bleus". But every change is offbeat ; for example, if player 1 gets a diamond block, the inventory of player 2 is empty, then when player 1 gets an emerald block, player 2 gets the diamond block but not the emerald block. How can I fix that ?

[fluid river]

why is there so much unused code

[compact haven]

my guess is that it’s a cancellable event and it’s dispatched before the inventory object is updated

you can put it into a schedule if u want

[fluid river]

just sync inv 1 tick later

[dry yacht]

First of all, I'd advise a few code changes to you in order to clean the code up and not perform unnecessary actions, but the reason is simple: The pickup event is called before the inventory is actually modified in order for you to have a chance to cancel pickup. Delay the code in the event by one tick (runTask on Scheduler) and your problem should be solved

[quaint mantle]

is paper multithreaded?

[compact haven]

negative

[fluid river]

is java multithreaded

[compact haven]

only chunk generation iirc

[quaint mantle]

is each command run in its own thread, asynchronously?

[compact haven]

is it?

[fluid river]

AsyncPlayerChat comes in

[opal juniper]

nope

only chat really

[quaint mantle]

okay.

[compact haven]

forgot about the chat event kekw

There might also be an async player join event

iirc, but I’d not take my word for it

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/AsyncPlayerPreLoginEvent.html

that’s what I meant

[spring minnow]

Would this change the compass direction with only That Compass?

because the player.setCompassTarget changes it for every compass

i would it only with that one

[dry yacht]

Packet I/O happens asynchronously, but bukkit often times synchronizes to the main thread in order for you to not have to do so before - for example - manipulating the world. I'm sure commands are parsed asynchronously and then the executor is invoked within the main thread. If you want async commands, you need to listen to the AsyncPlayerChatEvent (or whatever it's called), cancel it and continue to operate out of that async context.

[dry yacht]

The lodestone property of the CompassMeta of an item only affects that Item, yes.

[spring minnow]

ok thanks

[fluid river]

yes

well, im quite sure this code won't work

cuz modified itemmeta is not set back to an item after that

[compact haven]

this

[dry yacht]

Remember that getItemMeta always returns a new copy, representing the ItemStack's NBT, in essence. Modifying that copy does nothing until applied by calling setItemMeta again.

Error: A JNI error has occured...

[dry yacht]

The hardcore version of that would be to intercept the PacketLoginInStart and just close the pipe without any warning if they're banned, lol.

[fluid river]

JREE FAVA LESSONS

[fluid river]

Bukkit.getBanlist().addEntry(...)

[compact haven]

I actually never used the JNI before

🤔

well, directly at least

[fluid river]

you can just run 1.19.3 spigot on java 8 to get JNI erorr

[compact haven]

Can you invoke JNI manually? Is that like a thing

[fluid river]

like this one

[fluid river]

wdym

you can call a JNI method of course

[compact haven]

but actually, place a handler first in the pipeline and check the type manually using the byte buffer

[fluid river]

you just do System.loadLibrary(...) and run an associated native method

[compact haven]

interesting, will need to fuck around with that someday

[fluid river]

and well, code a .dll on c++ 64bit

to work with this method

i have a guide to hello world somewhere on my telegram java channel

native version

[compact haven]

I’ve never used telegram before 😂

[fluid river]

no worries, my channel is on russian anyways

[compact haven]

ah ic

[fluid river]

public class JNIExample {

    static {
        System.loadLibrary("exampleLib");
    }

    public native void helloWorld();
}```
```java
public class MainClass {

    public static void main(String[] args) {
        var jnie = new JNIExample();
        jnie.helloWorld();
    }

}```
```cpp
// c++: some generated shit after you run javac -h

[tardy delta]

what kind of exception do you get when you call a native method that isnt implemented?

[vale ember]

iirc UnsatisfiedLinkError

[tardy delta]

ah

[vale ember]

Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.

[fast sedge]

help?

anyone

can anyone say how this fix this multiscreen pls

I dont know most of hidden controls of IntelliJ

@ancient plank

@crimson jasper If you can?

@wild nexus ?

@mossy loom

?

Sorry for the Ping but.

[ancient plank]

Don't ping random people/staff for development help @fast sedge

[fast sedge]

Sorry

[rotund ravine]

What a disgusting theme

[wild nexus]

Yes

[rotund ravine]

Press view and look at the settings

[fast sedge]

Ok thanks

[austere wave]

Hello, I have this error when I try to call a kotlin class from a java file

Could not initialize class me.keano.azurite.coins.EconomyKt

[wild nexus]

Close every tab in the right

[remote swallow]

or just close the apps onthe right

[fast sedge]

I am just new to IntelliJ , Cause I used Eclipse.

[fast sedge]

Thank you guys and once more sorry to ping you and disturb you!

[analog vapor]

Ok so this might be a weird question, I wanted to make a quick plugin that would give me data when I input something, just that

[rotund ravine]

Just post and wait for an answer.

[analog vapor]

So I am totally new and totally understand spoonfeeding is illegal

[fast sedge]

ok.

[analog vapor]

is there any help I could get?

[rotund ravine]

It’s not. It’s looked down upon

[remote swallow]

?spoon is the reason

[undone axle]

Spoonfeed a newbie for a day and they'll come back with more questions. Teach them to find their own answers and you'll both be better off: you won't get stuck answering the easy questions and they'll be much more productive than before.

[analog vapor]

Not any good news either

[rotund ravine]

https://www.spigotmc.org/wiki/spigot-plugin-development/

[analog vapor]

Ah no worries 😅, I am newbie but I am in urgent help atm, I also have exams but I cant let the server I work for down

Huh?

[ancient plank]

The multitasking experience

[rotund ravine]

Whatever

[analog vapor]

The multitasking experience

[austere wave]

?

[analog vapor]

ok weird to ask, but can I get spoonfed once? I know its unacceptable but I need to get it done asap

[austere wave]

Does anyone know how to fix it?

[rotund ravine]

Askl chatgpt https://chat.openai.com/chat

[remote swallow]

depends on what

[rotund ravine]

Really can be anything

Where is that at

like do you build it properly

etc.

[analog vapor]

well it is supposed to be a simple minecraft mod where you input a number and get an output number as I can make the parameters to be

Like in the image below, if I enter 450, I want output to be P20 and Degree 45

[austere wave]

I built it with maven package command, the kotlin folder is separated from the java folder

[remote swallow]

mod? this is the wrong place for those

plugins are made with the spigot api

[analog vapor]

aw man

[remote swallow]

fabric or forge?

[rotund ravine]

did u tell maven to build kotlin properly?

[austere wave]

How?

[analog vapor]

fabric

[austere wave]

Kotlin is configured in the project

[remote swallow]

https://discord.gg/f3xhgDG6

[rotund ravine]

idk i use gradle

[analog vapor]

thanks ❤️

[rotund ravine]

fabric is great

hf with it

[rotund ravine]

There's no getNearybyEntities on the location object in spigot.

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

[olive lance]

is there a way to tell which version of spigot a plugin was compiled on?

[ocean hollow]

thanks, i made this

now it doesn`t have errors👍

[rotund ravine]

Hmm, well easiest would be to check plugin.yml for api-version

[olive lance]

right. not sure why i didnt think that

is there no way to get jre 19 without the jdk?

default jre download is 8

[rotund ravine]

well there probably is, but jre is not being bundled seperately anymore.

there is no reason to download it seperately

[olive lance]

why wouldnt there be any reason?

[rotund ravine]

@olive lance Why would there be a reason with the newer java features?

[olive lance]

i thought the jdk was only for development, is it required for running compiled code too?

[rotund ravine]

@olive lance The JDK includes a JRE.

[olive lance]

yeah, i mean all it is is wasted space if youre not going to use the jdk unless im wrong about that

[serene sigil]

hi, i have a question: how do you make a loop that starts whenever u open an inventory and stops when u close it?

[obsidian drift]

Is there a way to set Player.getItemInUse

and make it null

[jade roost]

how do i get a player's skull (heads)?

[obsidian drift]

Using SkullMeta

[serene sigil]

this is what i got until now

[remote swallow]

add a variable outside of that that can be set by 2 locations

in that scheduler check if the var is false

if it is cancel it but on the first run set it to true

[river oracle]

Use a map uuid bukkit task to track session

Make sure it's emptied on inventory close

[serene sigil]

how do i do that?

[river oracle]

You don't know how to make a hashmap?

[serene sigil]

no, i mean..

[river oracle]

Bukkit schedulers return BukkitTask variables just add them to the map with the p l ayers uuid

[river oracle]

Yeah but make it private static final

[serene sigil]

ok

[river oracle]

Also you might beable to store task ids look into that if you can just store the task Id

[ocean hollow]

Can I somehow refer to the collection by index?

[river oracle]

Yeah that's how you get things from a collection lol

[serene sigil]

i dont know how to do the bukkittask part

[river oracle]

Bukkit#getScheduler everything In that class returns a BukkitTask

[serene sigil]

okay

[river oracle]

Highlighted portion returns BukkitTask

[serene sigil]

yes

[ocean hollow]

so, it gives error

[serene sigil]

but like what do i put in here

[river oracle]

[tulip drift]

Using 1.8.8 how can I make a player punch/swing their hand.
On newer versions there is a player.swingMainHand() function.
However on older versions I think you have to send an nms packet, how can I do this and what packet do I send?
Thanks in advanced

[river oracle]

Packets

You won't recieve good support for legacy versions please update you can mimic the api with plugins

[tulip drift]

thats what im asking, how do I work out which packet to send?
