[steep nova]

if he's just copying the code word for word

[quiet ice]

It is exhausting to see someone complain that something does not work only to not know what does not work

[steep nova]

there's no hope

[quiet ice]

And what it should really do and what it actually does

[onyx shale]

i mean i think 2 learnjava cmds were used

[chrome beacon]

He is

[onyx shale]

plenty of links to learn java

[daring maple]

Which will probably be the case

[lunar schooner]

So just curious, how expensive is World#getHighestBlockAt()? It's specifically this call that is giving some very heavy performance issues.

[lean gull]

plugin is red

[steep nova]

why

[onyx shale]

tbh not that expensive

[quiet ice]

Did you use EnumSet?

[chrome beacon]

Yeah we know

[daring maple]

Did you get an instance of plugin

[onyx shale]

like you should be able to spam it with little to no effect

[chrome beacon]

Please learnjava

[lunar schooner]

Odd, might be in combination then with nearbyTorches.parallelStream().forEach((l) -> { ? 🤔

[lean gull]

idk what's enumset nor instance

[chrome beacon]

He didn't

[steep nova]

lmfaooo

[onyx shale]

not enough context

[quiet ice]

irrelevant for you

[daring maple]

then learn java

[steep nova]

do you have a plugin variable or not

[daring maple]

He does not

[steep nova]

bruh

[lunar schooner]

Yeah fair point. Maybe I should just not do maths on sync 😂

[onyx shale]

i hink the problem is he is trying to learn java through plugin making

wich is an awful ideea

[daring maple]

The guide he is following assumes you know how to create an instance of your main class, which he doesnt.

[onyx shale]

care as ur working with api so async will require some tricks

[quiet ice]

The bigger sin is not using SO

There is nothing wrong at it's core (of learning java with bukkit), but asking other people every time is wrong

[lunar schooner]

Hm fair point. Not sure if World.getHighestBlock at does too though

actually, I could probably just scrap it alltogether

[onyx shale]

you could grab snapshot of chunk

then work with it async

[lunar schooner]

Hm, could you explain that further?

[lean gull]

https://i.imgur.com/Jc2fcUx.png

[onyx shale]

a snapshot will give you a full copy of the selected chunk

[lean gull]

in main i have

    public String ifConfigValueIsSet(String ConfigValue) {
        return this.getConfig().getString(ConfigValue);
    }```

[onyx shale]

so no more api related to it,meaning you can do async

[daring maple]

I mean, I got into programming because of Bukkit. 🤷‍♂️

[onyx shale]

on it

[chrome beacon]

Please learn Java

[steep nova]

it returns a stringgggggggg

[lean gull]

right 1 sec

[steep nova]

this ^^^

[quiet ice]

Please use StackOverflow

[onyx shale]

think i have a code

1sec

[quiet ice]

Do not ask us, it only wastes YOUR time

[steep nova]

bro fr you won't be able to do this w/o learning java

[lean gull]

https://i.imgur.com/OMD0ZX5.png

[lunar schooner]

Does Bukkit have a snapshot function or would you say just Object#clone the stuff 🤔

[daring maple]

bruh

[quiet ice]

Just using SO is enough

[ornate heart]

Can someone explain to me why you shouldn't name your plugin's main class "Main?" I'm trying to explain to a friend why they shouldn't, but don't entirely know the specifics.

[daring maple]

.getString returns a string

[quiet ice]

not cloning, that far I can say

[steep nova]

isnt main with a lowercase m a protected word?

[chrome beacon]

Just confusing and bad practice

[quiet ice]

not that I think so

[onyx shale]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Chunk.html#getChunkSnapshot()

[lean gull]

and i put that where...?

[steep nova]

dude

[daring maple]

nowhere

[lunar schooner]

O.o that'd work, I can just take the nearest chunks (radius / 16 I suppose, and use that)

[iron condor]

can I compare getOpenInventory() with a custom inventory?

[steep nova]

learn basic coding first

[lean gull]

ok if you're gonna hate / say "learn java", i will block you :P

[steep nova]

lmaoooooo

[onyx shale]

yes,you can grab the chunk and do all the checks async

[stone sinew]

@onyx shale Material.matchMaterial() was causing the lag. Material.getMaterial() works right

[daring maple]

Welp good luck finding any help then

[iron condor]

do me a favor and block me as well please

[chrome beacon]

Maybe we should just block you

[steep nova]

fax

[iron condor]

[ivory sleet]

Floofsys block list extends beyond infinity soon lol

Anyways floofsy what was the issue

[stone sinew]

I mean the whole method is still laggier then on my test plugin but meh...

[lean gull]

conclure just look up in here

[ivory sleet]

Yeah but what were you trying to do?

[onyx shale]

https://www.spigotmc.org/threads/read-me-for-everyone-asking-questions-on-here.72946/#:~:text=Know your Java,bukkit.org/Plugin_Tutorial

[lean gull]

make a stored variable thing

[quiet ice]

sadly discord's block system is scuffed

[ivory sleet]

I mean all variables store stuff

[onyx shale]

plese click that link

[steep nova]

particularly this part

[lean gull]

well on memory

[lean gull]

i want on a file

[ivory sleet]

Sure

[stone sinew]

Testing

[chrome beacon]

It's basically non-static access. And he appears to be copy pasting code without any ideas of what things are

[stone sinew]

And IDK about "fast" clearly xD since the lumbjerack is lagging but clicking the arrow isn't

[onyx shale]

try moving stuff async

[stone sinew]

Im not using async with the arrow

[onyx shale]

i mean not for the arrow

for the checks

[stone sinew]

I'm trying to match the speed

They are using the exact same checks xD

Thats why I'm so confused lol

[shadow gazelle]

Okay, so, I'm making a crafting thing where you drop a custom book and chestplate on the ground and get the enchantment on the chestplate that was dropped. I have the code for removing the custom book if it was dropped with a chestplate, but I now need to edit the dropped chestplate. I don't know how to access the chestplate from what I have here, can anyone at least point me in the right direction?
https://paste.md-5.net/ojasapetad.cs

[daring maple]

He is trying to follow this guide: https://www.spigotmc.org/wiki/config-files/. However he does not seem to know much about code, thus gets stuck on this code not working.

[chrome beacon]

Yeah I'm aware

[daring maple]

Whoops, meant to tag Conclures message

[onyx shale]

please paste somewhere,md5paste throwing ssl error

[shadow gazelle]

Oh

Wait, what?

[onyx shale]

idk why

[shadow gazelle]

Loads for me

[daring maple]

For me too

[chrome beacon]

Works fine for me

[quiet ice]

Strict browser settings

[shadow gazelle]

Any ideas on how to get the item and edit it?

[lean gull]

oh sorry i meant these links:

[quiet ice]

Highly browser dependent if it works or not

[onyx shale]

post the code m8

..

[chrome beacon]

Malwarebytes does flag paste md5 as a trojan

;/

[shadow gazelle]

The link works for everyone but you

[onyx shale]

i do have malwarebyte active..

well im the one willing to help

so idk

[chrome beacon]

Whitelist paste md5 that's what I had to do

[shadow gazelle]

    @EventHandler()
    public void onItemDrop(PlayerDropItemEvent event) {
        Player player = event.getPlayer();

        if (event.getItemDrop().getItemStack().getType() == Material.DIAMOND_PICKAXE || event.getItemDrop().getItemStack().getType() == Material.NETHERITE_PICKAXE || event.getItemDrop().getItemStack().getItemMeta().getDisplayName() == ChatColor.LIGHT_PURPLE + "Telepathy Core") {
            for (Entity entity : player.getNearbyEntities(5, 5, 5)) {
                if (entity instanceof Item && event.getItemDrop().getItemStack().getItemMeta().getDisplayName() == ChatColor.LIGHT_PURPLE + "Telepathy Core") {
                    entity.remove();
                    
                }
            }
        }
    }

[onyx shale]

hmm beside ur problem i see some bad things

you should use the dropped item the pickaxe as the main entity the loop will be done

not the player

[chrome beacon]

Use an EnumSet

[onyx shale]

also u are working with entities

[chrome beacon]

Will look much cleaner

[lean gull]

this is the new code for the Main class:

    public boolean ifConfigValueIsSet(String ConfigValue) {
        if (this.getConfig().getString(ConfigValue) != null) {}
        return true;
    }```

[onyx shale]

so you should be able to simply do Item chestplate = (Item) entity;

[shadow gazelle]

I mean, it's dropped items

[lean gull]

no red lines, but the second class still has red lines

[chrome beacon]

That code does nothing lmao

[dusk flicker]

?conventions you should be following naming conventions

[undone axle]

Java Coding Conventions: https://www.oracle.com/java/technologies/javase/codeconventions-namingconventions.html

[onyx shale]

so you should be able to simply do Item chestplate = (Item) entity;

[daring maple]

this always returns true no matter what

[chrome beacon]

Ye

[lean gull]

oh yeah 1 sec

[stone sinew]

I hate that you can post more then one attachment

[onyx shale]

so nms block checking fkin ya?

[lean gull]

fixed it,

    public boolean ifConfigValueIsSet(String ConfigValue) {
        if (this.getConfig().getString(ConfigValue) != null) {
            return true;
        }
    }```

[onyx shale]

afaik there are like 5-6 ways each with different speeds

[stone sinew]

No the lumberjack just has more lag with the same methods xD

[onyx shale]

hmm strange

[daring maple]

this code will not work

it wont compile

[shadow gazelle]

You mean something like this?
Item chestplate = (Item) event.getItemDrop().getItemStack();

[lean gull]

for some reason the last curly braces are with red line below them

[daring maple]

yes because you dont always return something

[onyx shale]

depends... however i would take another approach

i wouldnt rely on the drop event

[lean gull]

fixed it

    public boolean ifConfigValueIsSet(String ConfigValue) {
        if (this.getConfig().getString(ConfigValue) != null) {
            return true;
        } else {
            return false;
        }
    }```

[ivory sleet]

btw floofsy this.getConfig().isSet(String path) exists

[onyx shale]

i would instead check every X ticks,each entity in the world,check if theyr items,check the type,check the nearby(a max range of 1),remove both,get location drop ur item

so this way if a item is alrdy on ground from a while

and you come and drop the rest

it will work

[shadow gazelle]

eh

[lean gull]

nope, it's red

[onyx shale]

rather than locking yourself to

the drop event

[lean gull]

i mean red line below it

[shadow gazelle]

hm

[onyx shale]

hopefully makes sense

[lean gull]

oh nvm fixed it

why does ifConfigValueIsSet have a red line below it? if (Main.ifConfigValueIsSet(uuid)) {

[chrome beacon]

..

[onyx shale]

also this will pretty much work for everything,even if a dispenser

does it

[daring maple]

If you hover over it, it will tell you

[ivory sleet]

Floofsy what about yeeting every static in your plugin

why do you keep spooning him ffs

[lean gull]

was just about to say "i don't even know what static is ¯_(ツ)_/¯"

[chrome beacon]

Yeah we know no need to show us

Now take the advice and learn Java basics please

We're not here to write you a plugin

[onyx shale]

the harsh truth

[lean gull]

also i can't help but notice that people that are blocked for me are talking (about this, i assume) and you guys do realize you're blocked which means i cannot see your messages, right?

[burnt current]

Hi, I have a quick question: What is the best way to store a PlayerInteractEntityEvent that is passed in a method in a variable that can be accessed throughout the class? I know I can do this somehow with public but I don't know how exactly to do it because everything I've tried has given me an error message. I also know that this is part of the basics in Java but although I have learned it, I unfortunately have no idea how to do it right now.
Thanks in advance

[onyx shale]

i mean soon

you will be kicked

if you continue

[novel lodge]

Is there an armor euip event?

[quiet ice]

You do realize that you deny help for other people by your presence

[onyx shale]

sadly rn nope,md is working on one,but in the meanwhile you can only use libraries

[lean gull]

wdym

[chrome beacon]

Could you show us what you tried?

[daring maple]

if you'd want to use it anywhere in your class you could use a private field

doesnt have to be public

[quiet ice]

Can't you pass it in a DI-style way throughout the methods of the class?

I sense static abuse otherwise

[onyx shale]

what is the outcome ur looking for?

[shadow gazelle]

If I use Bukkit.getOnlinePlayers, would I have to getPlayer before I can check a player for something?

[onyx shale]

getonlineplayers will return a collection wich you can loop

[shadow gazelle]

So I don't need getPlayer?

[onyx shale]

for(Player player : Bukkit.getOnlinePlayers())

[shadow gazelle]

I mean for something like this

                Player player = (Player) Bukkit.getOnlinePlayers();
                for (Entity entity : player.getPlayer().getNearbyEntities(3, 3, 3)){

                }

[onyx shale]

nope

not gonna work

you need to do a loop over the collection

[lean gull]

which player doe

[shadow gazelle]

So I don't need getPlayer?

[quiet ice]

no

[shadow gazelle]

https://tenor.com/view/nick-young-question-marks-what-excuse-me-huh-gif-4486363

[quiet ice]

getPlayer basically returns the player instance

[lean gull]

you're getting 1 player from a list, which player are you trying to get

[quiet ice]

the implementation is probably

public Player getPlayer() {
  return this;
}

[shadow gazelle]

...

[shadow gazelle]

I know, what he's saying makes no sense when I'm going through every player

[vital ridge]

Getting the block player is looking at needs raytracing right?

[quiet ice]

You are not

You are casting a Collection<Player> into a Player

[daring maple]

I think its a method of player

[quiet ice]

Which will CCE

[ebon siren]

you have to state the skull's owner, aka which user's head will be rendered on the skull

[vital ridge]

I mean i need to use raytracing for smthing

[burnt current]

I wanted to create a villager where, when you click on it, an inventory opens in which you can change various settings by clicking on items. One of them should be that this villager is killed.
On another Discord server I got the suggestion (because the PlayerInterActEntityEvent is in a different method than the one I need) to store the PlayerInteractEntyEvent in a variable and then call it at the respective place.

[quaint mantle]

Pretty much

[vital ridge]

so i basically need to add bunch of numbers to the players direction x y z

and then getting the block at that x y z?

[quaint mantle]

You can copy client code tho and implement it

Into your plugin

[vital ridge]

Id just like to learn raytracing myself lol

[quaint mantle]

That will teach you

You can optimize it how you wish

[eternal oxide]

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

[quaint mantle]

Don’t be passing your event around

Store data based off the event @burnt current

Then you can access it in other places

[vital ridge]

that doesnt work with water tho

Thats why i thought bout raytracing

i need to check if player is clicking water

I watched few tutorials and I think I got some kind of understandment of how raycasting works

so i just wanted to ask here

[quaint mantle]

Yea just do the raytracing it’s ez

I recommend

[vital ridge]

So raytracing is just adding a specific number to players direction x y z and then getting block at that x y z?

[burnt current]

How can I do that?
Do I need to have dealt with databases in Spigot for this?

[quaint mantle]

No you can store in memory

And @vital ridge look at the client it’s your best source of knowledge

[vital ridge]

You mean minecraft src?

[quaint mantle]

Either the client or the server

[chrome beacon]

Not sure why he's recommending that

[quaint mantle]

??? Why wouldn’t you go look at where all the knowledge sparks

[vital ridge]

How should i find raytracing snippets tho

[burnt current]

and how would I have to do that in that case?

[chrome beacon]

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

Use that

[vital ridge]

i cant check if targetblockexact is water

if i click on water it returns nothing

[chrome beacon]

You can

Use the FluidCollusion setting

[vital ridge]

Okay but im just wondering

[vital ridge]

is this even close to raytracing?

cuz i watched bunch of videos

[lean gull]

i still need help

[chrome beacon]

And we've yold you what to do

[burnt current]

@quaint mantle ?

[chrome beacon]

Store it in a variable

[burnt current]

yes but how exactly?

[daring maple]

Here we go again

[shy mortar]

Is there a way to apply a BaseComponent to the name of an itemstack?

I can't see a method for it

[dusk flicker]

Why do you need to?

Just use a string

[shy mortar]

because I'm converting from Adventure a minimessage parsed component into basecomponents, which can't be changed into strings

[chrome beacon]

Yep

[shy mortar]

paper 1.17 isn't out

hence why I asked

[chrome beacon]

NMS is the only way sadly

[shy mortar]

bruh

[chrome beacon]

Spigot API is a bit lacking with text components

sorry but I've already learned the Java basics but for whatever reason I just can't figure out how exactly to store this variable from the method so that I can use it in other methods. I don't want you to write my plugin, I'm just looking for help for this one line of code.

[paper viper]

learned the Java basics

can't figure out how exactly to store this variable from the method

these two don't go well together

sorry

¯_(ツ)_/¯

[granite stirrup]

LMAO it says Outdated server! Im still on {0}

when viaversion isnt loaded yet

[burnt current]

I don't want to argue with you now either. Thank you for your help

[dusty herald]

what else is it gonna do

[gaunt hatch]

oOOOo switch expression are nice

Good stuff going form 8 to 16

[dusty herald]

switch expressions are awesome

[daring maple]

switch expressions were also in 8

[granite stirrup]

no i meant it doesnt say what version

[gaunt hatch]

i never saw then in 8 or never recommended them

[dusty herald]

that's not what they meant beast

or not

you can directly put it into a variable iirc

[gaunt hatch]

Either way they are pretty 🙂

[daring maple]

yeah that is true

[gaunt hatch]

time to re-code some stuff lol

[dusty herald]

I've just started to use ResourceBundles

😳 I like them

[gaunt hatch]

omg my OCD!!!

its on the left ugh!!!

[unreal quartz]

tilt your monitor vertically then

now it's on the top

[gaunt hatch]

hahahaha

or change the location in the GUI

[unreal quartz]

i prefer my method

[proud basin]

nice one

[somber patio]

Yes hide the evidence, nobody needs to know 😛

[proud basin]

?snipe

[gloomy edge]

I'm tireddd

lol

Ok, so my code looks like this but it makes this

But

I don't want that I want

[gaunt hatch]

Bro pre-increment, please.

[paper viper]

you are checking if its a modulo of two

that is why its every 2 blocks

like the second block, 4th block etc

Instead, check that it isnt the first or last row, and not the first or last column

like for example

actually i cant give an example atm i dont got my ide open 😦

[gloomy edge]

I'm trying to comprehend this

[paper viper]

Well lets write the logic

here you know what maybe writing it would make more sense

for (int i = 0; i < 3; i++) { // column
  for (int j = 0; j < 3; j++) { // width
    if ((i == 0 || i == 2) && (j == 0 || j == 2)) {
      setdiamondblock stuff;
    } else {
      setironblock stuff;
    }
  }
}

as an example

[gaunt hatch]

pre-increment, its faster on the loop

[paper viper]

what?

[gaunt hatch]

for (int i = 0; i < 3; ++i) { // column

[paper viper]

The performance is negligible

[somber patio]

How is that any faster?

[gaunt hatch]

the way its grabs the value and returns it

[somber patio]

I can almost guarantee that the JVM optimises it to be the same

[gaunt hatch]

it does double the work on post then pre on the value increase

[paper viper]

this

the JIT does it for you

there is no point of doing it tbh

[gaunt hatch]

it doesnt lol

[paper viper]

even so, it is a negligible difference

[paper viper]

source?

[gaunt hatch]

Google it

[paper viper]

for the JIT not optimizing it

[somber patio]

What extra work would it be doing?

[gaunt hatch]

++i increments i and evaluates to the new value of i.

i++ evaluates to the old value of i, and increments i.

[paper viper]

Ah i see, I will be wasting 1 nano second

Mhm

this isnt even a micro optimization lol

[gaunt hatch]

it all adds up

[dusty herald]

one nanosecond?? ARE YOU CRAZY??

[somber patio]

but the value isn't ever used, so it just won't bother doing it

[paper viper]

ikr

one NANOSECOND

omg

[regal dew]

if i++'s return value is not directly used then it can be optimized, which is like 99.99% of the time

[eternal night]

but how does that prove the JIT doesn't optimise it o.O

[dusty herald]

it's so un optimized omg

[eternal night]

yea, I'd expect the JIT to just optimise it away

[dusty herald]

are u even a developer! No!

[regal dew]

the difference is with i++ the old value has to be copied, before it can be returned

but you really shouldnt care about this lol

[paper viper]

and also people who use ++i are actually cursed

for loops

[granite stirrup]

who cares??

[quaint mantle]

^

[dusty herald]

++i; looks so fucking wrong

[granite stirrup]

if u want to use ++i so then use it if u want to use i++ doesnt matter it isnt gonna be a big difference

[somber patio]

Also, you could argue that i++ gives better developer performance since it's more ubiquitous which is generally something that companies care a lot about

[paper viper]

And also you are using ++i in the wrong place anyways lmao

it makes other people think you arent using it correctly and/or dont know what it does

[granite stirrup]

i personally think i++ looks more nicer

[paper viper]

cause nobody writes code like ++i

in a loop

[dusty herald]

if it was that evil I bet my sonarlint would scream at me

[granite stirrup]

yeah whoever uses ++i is probs gonna be mojang

[dusty herald]

it screams at me for everything

[paper viper]

they use public fields too

lmao

like pretty often too

[granite stirrup]

lol

[paper viper]

i aint kidding if you look at their NMS

[somber patio]

Didn't someone need actual help before this tangent?

[paper viper]

you find a ton of public fields

[granite stirrup]

im not saying ur kidding

[dusty herald]

🤷

[granite stirrup]

im just saying that its pretty funny

[granite stirrup]

tbh idk

[dusty herald]

was it you Ivan?

[regal dew]

nothing wrong with public fields

[granite stirrup]

i just came here

[regal dew]

non-final public fields are a bit cursed though ;-)

[granite stirrup]

uh yes they are

[dusty herald]

private final void

[paper viper]

for the context of class properties

you shouldnt use public lol

[granite stirrup]

i like to use getter and setters

other than public

[paper viper]

only for singletons or utility methods

or class definition

use public

tbh

[dusty herald]

I usually have private shit for my secret classes

😉 😉

[gaunt hatch]

nothing is secret

[eternal night]

just as a heads up, the i++ and ++i generate the same bytecode

[dusty herald]

yes it is

[eternal night]

lmao

[paper viper]

Lol

[dusty herald]

yeah but one nanosecond

apparently

[eternal night]

inside the forloop end

[somber patio]

@gloomy edge this is probably the thing you care about. Replace the 2s and 3s appropriately. Also out of interest, where'd you learn to code? That code style is quite abnormal.

[granite stirrup]

package;
public class Jochyoua {
  private final String isSlow = "yes";
}```

[dusty herald]

my cars into some kinky shit

[granite stirrup]

what if u have a private class

package;
private class Jochyoua {
  private final String isSlow = "yes";
}```

[dusty herald]

if you reflect into my classes I will be angry

[gaunt hatch]

reflection is a killer lol

[granite stirrup]

i cant since 16 made reflection harder

[dusty herald]

bullshit?

is that bullshit

please tell me it is

[granite stirrup]

yeah u need a flag to use reflection?

[paper viper]

Nah hes not kidding

you cant modify final fields anymore

[dusty herald]

fuck java

😦

[granite stirrup]

lol

[eternal night]

well, only final fields

[paper viper]

thats why retrooper is pissed lmao

[eternal night]

also only static final fields

[paper viper]

cause his packet events i think

uses reflection

[eternal night]

which you couldn't even edit prior because they can/might have been inlined

[dusty herald]

have I reached heaven

[granite stirrup]

theres one fix to it isnt there but ur not allowed to use it really

also it might get removed

[paper viper]

where do you get this

[granite stirrup]

cuz isnt there that flag

[paper viper]

lmao

[dusty herald]

someone just called me "hello ma'am good day" -fucking ends the call-

[granite stirrup]

joch whAt country?

[paper viper]

just take the whole damn thing

[dusty herald]

india

[paper viper]

just take the whole thing

lol

[dusty herald]

oh

local store

[granite stirrup]

lol take all of them

[dusty herald]

I want to but I don't have any spare cash atm

[granite stirrup]

XD

u should come back there later

and take the whole lot then

[dusty herald]

they're like 4$

[granite stirrup]

f

[dusty herald]

I'm gonna apply at subway

get that crisp 7$ an hour

[granite stirrup]

does mc donalds do worse?

or better

[dusty herald]

better

[paper viper]

that whole thing costs 69 dollars

all the chick file sauce

no cap

[dusty herald]

Thats not too bad

I could sell it on the streets for 4.50

[paper viper]

each one 4 bucks, then 4 * 2 = 8. Then 8 * 4 rows = 32. Then 32 * 3 shelves

= 69

lmao

[granite stirrup]

thought it was $104

cuz i counted each of one in that picture

and thats 26 i saw

my mom has sunburns

on her skin

:(

poor her

they really bad to

[daring maple]

how did 32 * 3 convert to 69?

[paper viper]

Oh shoot

Uhhhhhhh

Yeah nobody say nothing

[granite stirrup]

96

[paper viper]

I meant 96 obviously

lmao

[daring maple]

so close lmao

[paper viper]

lol

[granite stirrup]

he flipped the numbers

oh wait

he must of looked the wrong way

while using the calculator

and he thought he saw 69

@paper viper is that correct?

[last sleet]

How are item lore stored? String, array...?

[granite stirrup]

List<string>

[last sleet]

Thanks.

[granite stirrup]

i think

[paper viper]

i read 23 instead of 32

[granite stirrup]

lol

[young knoll]

So with modern java you can no longer change private static final fields with just reflection, correct?

[ivory sleet]

I mean true constants could never be changed in the first place since they're inlined at compile time

[young knoll]

It's a map

I was hoping I could hook into Mojang's structure system with just a plugin, but alas it appears I cannot

[rich topaz]

Hey can anyone tell me if the Hexcolor codes work in 1.17 it doesn't work for me but there is also no error showing

[young knoll]

Are you using the spigot format

Or the common format other plugins use

[quaint mantle]

?paste

[undone axle]

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

[rich topaz]

nevermind im dumb

xd

[quaint mantle]

Idk, Item Durabiloty dosen?T work :c

Knowes somone an alternative for a repair command?

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

[rich topaz]

Which spigot are you using

[quaint mantle]

16.5

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/inventory/meta/Damageable.html

[quaint mantle]

1.16.5

[young knoll]

Cast your meta to that

[young knoll]

Do note this is not the same as https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Damageable.html

[cinder timber]

is there anyway to detect a players version?

[proud basin]

how come if the player doesn't have permission they can still break blocks ```java
public void onBreak(BlockBreakEvent e) {
Player player = e.getPlayer();
if (!player.hasPermission("volzo.build")) {
e.setCancelled(true);
} else {
return;
}
}

[quaint mantle]

Could somone please help me?

[rich topaz]

something like this

ah no setDamage()

got the wrong import

[eternal oxide]

Your event is either not annotated or your listener isn;t registered

[proud basin]

It's registered

getServer().getPluginManager().registerEvents(new BreakBlock(this), this);

[eternal oxide]

then its no annotated with EventHandler

[proud basin]

what he said

[eternal oxide]

the only other thing then can be is you are oped

[proud basin]

testing with an alt

and they don't have op

also my annotated you mean @EventHandler correct

[eternal oxide]

then the final two things. They have the permission or your plugin is not on the server

[eternal oxide]

yes

[gloomy edge]

This makes this?

[paper viper]

send code

like your full code

[sage swift]

right here, right now

[paper viper]

[stone light]

I keep getting this error when running my plugin
[Server thread/ERROR]: Could not load 'plugins\TerrorGamesTest9.jar' in folder 'plugins'
org.bukkit.plugin.InvalidPluginException: java.lang.UnsupportedClassVersionError: ``me/TerrorGames/SurvivalGames/Main has been compiled by a more recent version of the Java Runtime (class file version 8243.8224), this version of the Java Runtime only recognizes class file versions up to 59.0
This error only shows up for my Main.class and all my other classes are working fine, also I compiled it in java 1.8 I don't know if there is anything else I need to add but thats pretty much it

[young knoll]

IIRC ViaVersion has an API for this

[granite stirrup]

thats fake right....

theres no such thing as 8243.8224

[stone light]

no everyone thinks it is and thats why I'so confused

yeah ik

[granite stirrup]

unless ur in like 8080

[sage swift]

java 8000 when

[young knoll]

I assume you have tried recompiling it

[stone light]

I've looked through the entire thing and those numbers never show up anywhere

[last citrus]

I have an error when loading the plugin someone made me. Can someone help me? https://hastebin.com/fevezakoki.apache

[stone light]

yeah

[paper viper]

its not inside your code, its whatever java version its compiled with

and idk how, but you must have some corrupt jdk

or something

lmao

[stone light]

Its compiled with javaSE 1.8

[granite stirrup]

it couldnt find a class lol

[young knoll]

Following the current version system, class file version 8243 would be java 8190

[paper viper]

lol

[last citrus]

How do I fix it? Here is the github https://github.com/SushiPython/textgen

[random wedge]

assuming 6 month release periods how many years into the future would that be lol

[granite stirrup]

idk u might have to shade jda in ur project

[gloomy edge]

Sorry but it's,

[somber patio]

You want to || not &&

[paper viper]

Yeah mb

i meant || there

lmao

[last citrus]

? Srry im new to java

[young knoll]

4087 years from now

[granite stirrup]

idk

ima go

[last citrus]

ok

[stone light]

apparently I'm from the future or smth then

[gloomy edge]

Thanks! @paper viper && @somber patio

[somber patio]

@stone light are you 100% sure that you're compiling with java 1.8?

[paper viper]

np

[stone light]

pretty sure I can send a screenshot if you want

[young knoll]

Fix the build path error

[stone light]

wdym?

[somber patio]

Also I'm not sure if that proves that you're using java 1.8 to build. To be honest I have pretty much no experience with programming Java in the context of MC mods, but that looks like a project Java version which I think maven probably doesn't use.

[young knoll]

You have a red X on the project itself

Which usually indicates a build path error

[stone light]

oh okay any clue how I can fix that? This is my first time ever trying to make a plugin

[young knoll]

Check the problems window in eclipse

[stone light]

okay I'll look at it

[hardy valley]

if (SkyPremium.getPlugin().getConfig().getConfigurationSection("Users." + e.getPlayer().getName()).contains(String.valueOf(e.getPlayer().getUniqueId())))) {
            ConsoleCommandSender console = Bukkit.getServer().getConsoleSender();
            String command = "/authme forcelogin " + e.getPlayer();
            Bukkit.dispatchCommand(console, command);
        }

I would like to make like a /premium system but I am not sure if this condition works. Is it correct?

[granite stirrup]

that seemss dangerous

like someone could take someones name

and if they have premium

they could just auto login

[regal parcel]

So what is the proper way to make a Goat ram something? Are we just calling the setTarget() on it or the attack() or is there some kind of "ramming" API that is planning to be added?

[proud basin]

how could I use PlayerMoveEvent with a command?

[granite stirrup]

u have to check for chat i think

idk

what are u trying to do??

[proud basin]

So if someone had typed /blblab and they moved wihtin 50 seconds the command is cancels

[young knoll]

Add their uuid to a set and then check that set in the move event

[proud basin]

ok thanks

[stone light]

okay I think I figured out the whole time traveling into the future thing so now this is the only error I get and I don't know what I need to do
Syntax error on token "module", interface expected
This is the code causing it:
module TerrorGames {
}

[upper vale]

how can i knockback all players in a radius away from a location

with the velocity decreasing as they are further awar from the loc

[somber patio]

This is very speculative since I don't even know what modules are in Java, but I don't think whatever TerrorGames is should be a module.

[vital swift]

        ItemStack item = new ItemStack(Material.LEATHER_CHESTPLATE);
        ItemMeta meta = item.getItemMeta();
        ArrayList<String> lore = new ArrayList<String>();
        lore.add(ChatColor.GRAY + "Health:§c +" + "35");
        meta.setLore(lore);
        meta.setDisplayName(ChatColor.DARK_PURPLE + "Chestplate");
        item.setItemMeta(meta);
        ShapedRecipe recipe = new ShapedRecipe(item);
        recipe.shape("F F", "FFF", "FFF");
        recipe.setIngredient('F', Material.ROTTEN_FLESH);
        Bukkit.addRecipe(recipe);
    }```
Is it possible to use custom ROTTEN_FLESH? like custom ItemMeta **named**, how?

[young knoll]

RecipeChoice.ExactChoice

[stone light]

I don't know how or why but somehow my code was compiled by major class version 8243 still

[somber patio]

How do I go about submitting a change to a NMS patch? I want to change nms-patches/net/minecraft/server/players/SleepStatus.patch, but the documentation I've found doesn't explain how to do that. Maybe I'm just being thick though.

[granite stirrup]

u have to learn how to use patch files and stuff

theres probs like a patch file editor or something

idk

[eternal oxide]

have you messed with your java JDK install?

[last citrus]

Can someone please tell me how to fix this: https://hastebin.com/fevezakoki.apache Im new to java

[eternal oxide]

INFO java.lang.NoClassDefFoundError: net/dv8tion/jda/api/hooks/ListenerAdapter

[paper viper]

you need to shade it in

[eternal oxide]

you are missing a dependency

[vital swift]

i think you need maven or gradle

[last citrus]

How do I shade

[vital swift]

Do you use eclipse?

[eternal oxide]

You may not have to shade. All depends on what the lib is

[vital swift]

jda

[last citrus]

I use Intelij

[vital swift]

i recommend watching https://www.youtube.com/watch?v=tlwn2YMnbrw&t

and then watching the next episode

It shows how to use JDA and etc

its this: https://www.youtube.com/watch?v=D211Wrj6VTA

[last citrus]

Intelij is putting warnings on these what should i do?

[vital swift]

bump

[somber patio]

You should probably know the difference between floating point and integer division if you're asking for help here.
Warnings should mostly be fine to ignore though.

(And to actually answer your question, change the 2 to 2.0 (or I think 2f should also work)

[last citrus]

A dev made me the plugin. Here is the source code. I had to compile it. Maybe I did it wrong?

https://github.com/SushiPython/textgen

[somber patio]

The developer probably should have shown you how to actually use their code. Is this something you paid for?

[last citrus]

They showed me how to use it. I just think im doing something wrong. They sent me a java lib to import so I imported it. I dont know if I did it right though

How to plugin works is when someone in discord does !normal {message here} it will build it in game. It wont connect to the bot though

[somber patio]

Are you actually getting any compilation errors? Warnings should be fine to ignore.

[last citrus]

No

Just these errors i think

[somber patio]

So you have a .jar file that you can put in the plugins folder? What happens when you open the server with the plugin in the plugins folder?

It should print out "Plugin Starting" at some point

[last citrus]

It gives me this error in console https://hastebin.com/raw/fevezakoki

[somber patio]

OK again I have very little experience with this but I think you might have to install the JDA plugin.

[gaunt hatch]

well that is a first i have npc's spawning for npc's lol

[last citrus]

Can I get that in inteliJ

[granite stirrup]

i think what he needs to do is shade jda into his jar

[last citrus]

Idk how to shade

I didnt make the plugin

[granite stirrup]

maven shade plugin ?

[last citrus]

I paid a dev to make it for me

They said I needed to compile it and add the discord bot token to the code

I did both but I get that console error

[granite stirrup]

well jda isnt a lib in mc

so u do need to somehow get it into there

like it cant find the jda classes

so u probs need to shade them into your plugin jar

[somber patio]

Do other plugins use libraries? How are those added to servers? For forge mods you just copy the library's jar file into the mods folder, are bukkit/server libs the same?

[granite stirrup]

no

[indigo iron]

can someone please look over my code
it is not giving me the item when i run the command
https://hastebin.com/yejazehasi.typescript

[granite stirrup]

jda isnt a mc plugin

[last citrus]

I have no other plugins on the server I am trying to use it on

[granite stirrup]

its a lib for java

[somber patio]

Oh you're right I really am just being thick.

[granite stirrup]

u need to rename onDaily to onCommand

actually idk

thats not how u do things

[dusty herald]

your class also needs to extend CommandExecutor and that method needs to be @Override

it's very messy but it would work

[last citrus]

I added the lib

[indigo iron]

then it says I need to rename my second onCommand

[dusty herald]

King, make multiple classes for each command

[granite stirrup]

^

[dusty herald]

well one class for each command

[eternal oxide]

he need override but he doesn;t need to extend. JavaPlugin does that

[granite stirrup]

thats easier to handle to

and u wont get confused which command is which

https://www.spigotmc.org/wiki/create-a-simple-command/

[last citrus]

I added the JDA lib. Now what

[dusty herald]

🤔 didn't realize you could register a command through just JavaPlugin

[lean gull]

can someone help?
https://i.imgur.com/vWRHSs5.png
(in Main)

    public boolean ifConfigValueIsSet(String ConfigValue) {
        return this.getConfig().isSet(ConfigValue);
    }```

[eternal oxide]

it is automtically registered to your main class if you don;t redirect it

[somber patio]

GIve people some time to reply.

[granite stirrup]

i think hes talking about the onCommand event

or something

[somber patio]

I don't think the way you've added the library has actually added it to the build environment

[last citrus]

oh

how do I add it

[lean gull]

i do not know what an instance is / static abuse

i have

i have watched a long tutorial and i am following the code academy java tutorial

[somber patio]

Are you compiling using maven? It looks like it's already adding it as a requirement at https://github.com/SushiPython/textgen/blob/main/TextGen/pom.xml#L79-L84
so I think if you're compiling with maven it should auto-add the stuff?

[vast sapphire]

you aren't going to know a lot of things at the start, things should click however within a year for plugin development. I'm in the same position as you right now but i do enjoy making little plugins.

[last citrus]

I’m compiling using intelij i think

[granite stirrup]

install maven

and do mvn package

[last citrus]

Ok

[lean gull]

people find it hard to understand that i enjoy making plugins and learning along the way

[granite stirrup]

actually

click the maven tab

and find the package command

[last citrus]

?

[indigo iron]

ty so much guys ❤️

[vast sapphire]

It's the best way to learn, I learn by example mostly.

[granite stirrup]

i learn from forums

[last citrus]

Ok

[vast sapphire]

    @EventHandler
    public void onFireballHit(ProjectileHitEvent event) {
        Fireball fireball = (Fireball) event.getEntity();

        ItemMeta meta = item.getItemMeta();
        String name = meta.getDisplayName();
        Location fireballLocation = fireball.getLocation();
        World world = player.getWorld();
        if (name.equals("§6CUSTOM STICK")) {
            if (item != null) {
                world.createExplosion(fireballLocation, 10, true, true);
                world.playEffect(fireballLocation, Effect.MOBSPAWNER_FLAMES, 10);
                world.playEffect(player.getLocation(), Effect.BLAZE_SHOOT, 10);
            }
        }
    }``` should I have ProjectileHitEvent for this?

[granite stirrup]

click on the copyright in mc and hold space and ctrl lol

[lean gull]

it's unlikely, but a player can switch a world between the time they fire the fireball and when the fireball lands

which could cause some big problems to your world

[vast sapphire]

what event should I have?

[granite stirrup]

https://discord.com/open-source

[vast sapphire]

ah ok

[lean gull]

isn't he already doing that by setting the variable fireball to the proiectile parsed as a fireball?

how so

yes but he is parsing it as a fireball

[vast sapphire]

true

[lean gull]

um i don't know java and you clearly do but isn't he just setting a variable to the entity and parsing that variable to a fireball?

[vast sapphire]

alright i got the fireball to cause the massive explosion however only when i fire two fireballs

if I fire a single fireball it causes a normal explosion

[gaunt hatch]

hmm do the spigot java doc have more then this?

[lean gull]

PXXD another problem, a more likely one, the player can switch held items between the time they fire and when the fireball hits

[lean gull]

all g 👍

yep

[gaunt hatch]

So it looks like it is hitting a fireball entity

Might need a check to validate the entity hit is not a fireball also

[vast sapphire]

i already have spawn fireball in another function

ok

[gaunt hatch]

i hate concurrent errors lol the worst to fix

[vast sapphire]

how would I do that? if projectile hit event is not fireball or something?

[gaunt hatch]

one sec

[lean gull]

someone pretty plz pls help

[gaunt hatch]

There should be a object in that event that will let you get who you hit, then you check that class isntance to see if its a ball or w/e you want to check

[vast sapphire]

ok

[somber patio]

@lean gull I think we're gonna need more than just that code

Specifically it would be nice to know what's in Main

[spiral roost]

Anyone know if you can color the SPELL_MOB particle in 1.15.2?

[vast sapphire]

if (event.getEntity().getLocation() != fireballLocation ) is that it or something close? still new to java

[spiral roost]

You'll probably want to use ! ...getLocation().equals(fireballLocation), just a heads up.

[vast sapphire]

oh ok

[spiral roost]

But uh, judging by Doc's response, that's probably not correct to begin with.

[somber patio]

Isn't exactly comparing floats generally not a great thing? Would it make sense to check that the distance is larger than some small distance?

[spiral roost]

Yea I have no clue what he's trying to do. I haven't looked at it. But what you're saying is true ye

[vast sapphire]

just a simple fireball stick with stronger fireballs

[plucky comet]

Hey im wondering does anyone have a good sql class to create tabeels get values insert and update

[ivory sleet]

I mean isn't that quite basic?

[dusty herald]

I normally use an enum class for that sort of thing

[gaunt hatch]

something like this

[dusty herald]

very messy but here

[plucky comet]

It is im still very new to java and learning databases today. I have a good one for python but not hava

[ivory sleet]

Ah do you know sql itself?

[gaunt hatch]

    @EventHandler
    public void onFireballHit(ProjectileHitEvent event) {
        
        if (event.getHitEntity() != null && event.getHitEntity() instanceof Fireball)
        {
            
        }
        
    }

[dusty herald]

https://paste.lucyy.me/obetavucup

[plucky comet]

no

[gaunt hatch]

You check if the hit is not null and is fire ball check

[north ridge]

If you dont want to deal with sql directly. Give any ORM a try.

[ivory sleet]

A good tip would be to learn SQL first before learning how to use it in Java

[gaunt hatch]

you can adjust the if checks

[ivory sleet]

🥲

[vast sapphire]

ok thanks

[north ridge]

Ayy, you got accepted.

[plucky comet]

what is ORM

[north ridge]

Object Relational Mapping

[gaunt hatch]

Do you get what its doing?

[ivory sleet]

Yeah very pog ty 🙂

got me thinking of korm

😌

[north ridge]

sx 🥲

Is he still working on it?

[ivory sleet]

Uh no he pretty much abandoned everything when leaving the community I believe

[north ridge]

rip

[ivory sleet]

yeah it had such potential

[vast sapphire]

I can pick it out, you are getting the hit entity and making sure it's not equal to nothing (which is what null is ig) and you are making sure that it is not an instance of fireball

[hardy swan]

wouldn't null not be instanceof Fireball, so you just need the second half anyways

[gaunt hatch]

that is why i said he can change it

[hardy swan]

oh

[gaunt hatch]

sometimes you need to give a little error so they can learn lol

[torn shuttle]

round 2: is there a hard limit on how often a mob can damage different entities (not the same entity) within a tick?

[gaunt hatch]

yes : damage frames

[torn shuttle]

that applies to non-player entities?

[gaunt hatch]

everything that can be damaged

LivingEntity:setNoDamageTicks

[torn shuttle]

but hang on

that's for the entity getting damaged, surely

[vast sapphire]

can I change projectile speeds?

[torn shuttle]

is noDamageTicks for the damager or for the damaged?

[gaunt hatch]

damage frames are a time limit where the entity can take no damage at all

[torn shuttle]

right so that's specifically what I excluded in my question

[gaunt hatch]

Your not getting it

[somber patio]

Does BuildTools set git user.name globally, or am I going crazy?

[gaunt hatch]

EVERYTHING!! there is no one person limit it everything or nothing

[torn shuttle]

round 3: is there a hard limit on how often a mob can damage different entities (not the same entity) within a tick?

[gaunt hatch]

no, cause its everything

[torn shuttle]

what

are you just not reading the question

[gaunt hatch]

once its hit buy one entity the damage frames are enabled and nothing can damage it

[torn shuttle]

I'm asking for the damager

not the damaged

[gaunt hatch]

....

[torn shuttle]

as in

a zombie that hurts 5 different players in the same tick

is there a limiter on that

[gaunt hatch]

oh that is not how that is worded lol

[torn shuttle]

yes it is

[north ridge]

I dont think theres a limit on that Magma

[vast sapphire]

I'm not sure how to change this here?

[gaunt hatch]

is there a hard limit on how often a 'single' mob can damage different entities at the same time. (not the same entity) within a tick?

that would make sence to what your asking

I do not think there is a limit

[north ridge]

how often a mob can damage different entities (not the same entity)

[gaunt hatch]

Yea that does not read the same for me, sorry lol

[hardy swan]

the predicate can be simplified

[north ridge]

lol

[torn shuttle]

well not how often, you can do it as often as you want, I am asking specifically within a tick

[gaunt hatch]

i dont think so

[hardy swan]

i mean, there is sweeping edge

so....

[gaunt hatch]

yea i coded that out day 1 lol

[torn shuttle]

I have some code that iterates through players in a range and damages them but for some reason it keeps only picking up the first player

[glossy scroll]

where can i find the changes to java reflection from 1.8 to 1.16?

what version did those changes take place?

[vast sapphire]

.

[north ridge]

Could you link us to the source?

[vast sapphire]

.

[torn shuttle]

    private void doDamage(EliteMobEntity eliteMobEntity, double range1, double range2, double range3) {
        for (Entity entity : eliteMobEntity.getLivingEntity().getNearbyEntities(range1, range2, range3))
            if (entity instanceof LivingEntity)
                BossCustomAttackDamage.dealCustomDamage(eliteMobEntity.getLivingEntity(), (LivingEntity) entity, 1);
    }

sure

[vast sapphire]

I'm going to spend some more time learning java

are videos a good learning source?

[torn shuttle]

no

[vast sapphire]

I use pluralsight

[hardy swan]

oracle has a pretty awesome tutorial site

[north ridge]

Pluralsight is great

[hardy swan]

but you have to like reading

[torn shuttle]

?learnjava

[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.

[vast sapphire]

I do have a java book

[torn shuttle]

link #4 was submitted by me

[hardy swan]

trust me, go for the last one

it would take much longer, but with less misconceptions

[torn shuttle]

this is really annoying to diagnose, I can't even tell if it's working or not

[plucky comet]

If only there was a program that converted python code to java

[ivory sleet]

hmm pretty sure a py -> java transpiler exists somewhere

but its probably not very good

[torn shuttle]

they do

they aren't

fuck this

as far as I can tell this works 10/10

idk why some people report it not working

there's hardly any code to it too

[gaunt hatch]

it looks fine

unless something is calling it werid.

[torn shuttle]

it isn't

[gaunt hatch]

yea the loop looks fine

[torn shuttle]

I can test it with zombies and this doesn't run any different, aside from a check to see if they're in creative or spectator mode

[gaunt hatch]

8 point grid

[vagrant stratus]

Might not be that hard to make a decent one, just time consuming 👀

[torn shuttle]

north_east is 8 point north_north_east is 16 right

[ivory sleet]

@quaint mantle

[gaunt hatch]

yea 16 my bad

[quaint mantle]

Ahh that helps visualize

[torn shuttle]

did you not have geography classes

[gaunt hatch]

oof

[ivory sleet]

I didnt learn this in my geography class lol

[quaint mantle]

Last time I had geography was probably 5-10 years ago

[torn shuttle]

you'd think they'd teach compasses in geography classes

[fickle helm]

what is the correct way to run a task on the main thread that is currently inside an async thread?

[torn shuttle]

last time I had geography was 12 years ago but I still remember the stuff that was vaguely useful

[gaunt hatch]

call back to the main thread

[ivory sleet]

Bukkit.getScheduler().runTask(plugin, () -> {

});

[fickle helm]

I tried this:

        Bukkit.getScheduler().runTask(main, runnable);```

[ivory sleet]

nono

[gaunt hatch]

omg no

[ivory sleet]

BukkitRunnable is capable of scheduling itself

no need to use the scheduler to schedule it

[gaunt hatch]

look into SynchronousOperation from a async thread

you can call a await with a SynchronousOperation and have it call back and wait for a response or not and have it just go.

[ivory sleet]

is there even something called SynchronousOperation?

[gaunt hatch]

i might have called it that one sec let me check lol

oh yea oops lol

its the idea of it

Yes the idea is call SynchronousOperation

you can google that to see

[fickle helm]

the main issue is I have an async repeating tasks that calls this:
for (final Player player : Bukkit.getOnlinePlayers()) {
which works great in 1.16 but on 1.17 I get:

java.lang.IllegalStateException: Asynchronous Chunk getEntities call!
        at org.spigotmc.AsyncCatcher.catchOp(AsyncCatcher.java:14) ~[spigot-1.17.jar:3124-Spigot-66f9d3c-384e116]
        at net.minecraft.server.level.WorldServer.getEntities(WorldServer.java:1795) ~[spigot-1.17.jar:3124-Spigot-66f9d3c-384e116]```

[ivory sleet]

yup

u cant do that async

[hardy swan]

do you need that operation to be within the async thread?

[fickle helm]

nope, just need a reoccuring task

[hardy swan]

oh then just lag the server out

lmao

[fickle helm]

ideally it'd be async but looks like I can't enumerate all players that way

[hardy swan]

for cant enum async

I believe you are looking for parallel streams

[hardy swan]

Whats wrong with this tho

[fickle helm]

it is deprecated apparently. I get an error also

[hardy swan]

Try runnable.runTask()

[fickle helm]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/scheduler/BukkitScheduler.html#runTask(org.bukkit.plugin.Plugin,org.bukkit.scheduler.BukkitRunnable)

that was the first thing I did and I still get the Asynchronous Chunk getEntities call! error

[oblique mural]

I am trying to get the block that was hit by a snowball, and looking at the javadoc, ProjectileHitEvent should have a #getHitBlock() method, however in my IDE this does not appear to be the case. What am I doing wrong?

[fickle helm]

What API version are you running?

[granite stirrup]

spigot api version?

[fickle helm]

yup

I'm using 1.17 and have it. Not sure what version they added that function in.

[oblique mural]

Oh, whoops. I'm adding this to an old project that has 1.14 imported

I'll update it real quick I'm sure thats the problem

[granite stirrup]

all i know that its defiantly in 1.16.3 api

https://web.archive.org/web/20200921195554/https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/ProjectileHitEvent.html

it might of been added in 1.15?

i also know it didnt exist in 1.13.2

also now we know its not in 1.14

[ripe marlin]

any1 know how to export to intellij with recaf

[granite stirrup]

?

[oblique mural]

Yup, updated to the latest buildtools build and all is well. Thanks guys

[ripe marlin]

its a decompiler

im tryna put some1s jar file into intellij

[granite stirrup]

yeah idk

this is for spigot stuff

[ripe marlin]

the jar im tryna put there is a spigot plugin

[vagrant stratus]

You'll have to make a project & move the decompiled source to it, assuming intellij doesn't have some built-in method

[granite stirrup]

why cant u use java decompiler

[ripe marlin]

it is

it has like no export function for whatever reason

the export just gives me another jar

[granite stirrup]

http://java-decompiler.github.io/

use that

it has export

[ripe marlin]

ok

[granite stirrup]

it export as a jar tho

so u have to extract the decompiled code

out of the jar

by using something like winzip

[ripe marlin]

how do i do that

[granite stirrup]

winrar

.jar files a legit .zip files

lol

https://plugins.jetbrains.com/plugin/7100-java-decompiler

theres a plugin for it for intellij to

dont think its official

i mean doesnt intellij already decompile jars?

[vagrant stratus]

https://tenor.com/view/elmo-shrug-不造-i-dont-know-gif-5094560

[ivory sleet]

might be adding another decompiler u can choose

iirc intellij uses fernflower be default

[granite stirrup]

intellij does decompile jars if u open one
