Store whatever you want

Shove an entire itemstack in there

[torn shuttle]

oh boy I sure hope me making a floodfilling algorithm can then be used to implement a* on top of it

[ancient plank]

I do

[young knoll]

Store the entire world in an items pdc

[smoky oak]

wont work

[torn shuttle]

personally I store the US constitution on every paper a server generates when using any of my plugins because I just think it's an important document to preserve

[ancient plank]

<plugin_acronym>_<type>_<name>
so rpe_bomb_thanhium

[torn shuttle]

you never know when you might need a backup of that document

[young knoll]

Why use the plugin acronym

[torn shuttle]

that's peasant numbers, I'd have billions of copies by now

[ancient plank]

because it's easier to read than roleplayevents_bomb_thanhium

some of my plugins have really long names

[young knoll]

Why have it at all

Just do bomb_thanhium

[ancient plank]

in the very very very small off-chance that someone else has a thanhium bomb plugin and goes "yeah lets make my pdc identifier "bomb_thanhium"

[young knoll]

But

Pdc is namespaced

So it wouldn’t conflict anyway

[ancient plank]

I care not

[fiery prairie]

this happens when i try to package (compile) my plugin. what exactly do they mean with POM?
The goal you specified requires a project to execute but there is no POM in this directory (C:\Users\SMTHNG\Desktop\untitled\target). Please verify you invoked Maven from the correct directory. -> [Help 1]

[young knoll]

But but

My precious bytes

[ancient plank]

maven

[fiery prairie]

well there was never a pom.xml in the /target/ of my project folder

or am i supposed to choose the project folder as the compile directory?

[young knoll]

You need to run maven from the folder that has the pom

[fiery prairie]

Ohhh

[tropic ingot]

New day, new problem ahah
What I should do is that: when a player presses the right button on an iron door, the iron door switches from closed to open (not the other way around, so once opened it stays open, unless it closes with vanilla methods)
however i can't make the plugin understand when the door is closed and how to open it, can you help me?

[fiery prairie]

it works now, thanks

[tropic ingot]

Yes, but I have to register the variable that tells me if the door is open or not (isOpen) and I have to be able to modify it (setOpen).

But I can't register the variable.

door.isOpen is red, so it doesn't give me the value true or false

[young knoll]

doorData.isOpen

door is a block

Block does not have isOpen

[young knoll]

Ah

You need to cast it to Openable

Openable extends BlockData and has an isOpen method

Yeah that works

[tropic ingot]

Can you send me the code strings please?

[young knoll]

No

Spoon feeding doesn’t help anyone learn

:p

[tropic ingot]

Ok now it works, thanks

[young knoll]

He had openable in a previous screenshot

But yes the docs will have that

[ancient plank]

doors are openable

Fun fact

[young knoll]

Fake news

[tropic ingot]

Bring me the evidence about it

[vivid cave]

how to retrieve skull entity at block-location x y z?

[torn shuttle]

what's the least painful way of doing pathfinding in the year of our lord 2022?

mappings?

[young knoll]

Probably

Certain fork has an api for it

Not sure how in depth it is

[torn shuttle]

yeah I know forks have an api for it but I'd prefer to keep it spigot-compatible

I mean how bad can basic "go in a straight line" pathfinding be, anyway

[young knoll]

Not hard

[hushed pawn]

can someone explain how movement in minecraft works? how to make npc jump for example?

[echo basalt]

well

do you want a very deep explanation or something just very shallow

if you want a deep explanation I'll go into what packets are sent and what triggers those packets

[torn shuttle]

I'll be doing this after the gym, out of curiosity are there any pathfinding resources out there using mappings?

[echo basalt]

by pathfinding you mean PathfinderGoals or navigation?

[torn shuttle]

I was thinking goals

[hushed pawn]

if you don't mind)

[echo basalt]

I can write something up

[torn shuttle]

if I just want the mob to move from location to location it's goals right?

[echo basalt]

That's navigation

[torn shuttle]

ah

wait then what was goals?

[young knoll]

Just look at vanilla ones

[echo basalt]

goals are for example, making a mob scared of others

type thing

[torn shuttle]

oh huh

[echo basalt]

goals are how a mob thinks

[young knoll]

For example, look at how cats go sit on chests

[echo basalt]

navigation is movement

[torn shuttle]

yeah I get it

[grim ice]

#1012313792488681492 still looking

for help

[onyx fjord]

what are applicable materials for BLOCK_MARKER particles?

[echo basalt]

All of them maybe?

[young knoll]

Any

[onyx fjord]

wait

rly?

[torn shuttle]

I'm making a TD game and I have my own A* implementation going, all I need is to tell the entity to walk along the path I defined

[echo basalt]

yeh

[young knoll]

Yep

[onyx fjord]

no way

[young knoll]

Some will be weird though

[echo basalt]

oh fun

[onyx fjord]

like barrier or what

[young knoll]

For example skulls will show as soul sand

[echo basalt]

Basically

[quaint mantle]

grass will be gray and stuff

[onyx fjord]

DAYM that sounds fun as fuck

[echo basalt]

I m making a TD game and I have my own A

[quaint mantle]

How would I use reflection with mojmaps?
Just suffer and look up the spigotmap equivalent?

[young knoll]

Yep

Afaik

[quaint mantle]

-<

[torn shuttle]

fyi game will be free once it comes out, keep an eye out for eternal td on spigot, a prototype should be ready real soon

[onyx fjord]

average nms moment

[quaint mantle]

Fabric ftw :D

[echo basalt]

magma

[quaint mantle]

yes

[echo basalt]

I'll talk about navigation on the thread I made

[onyx fjord]

name 1 nms user that doesnt suffer

[young knoll]

Forge has a helper for reflection

I assume fabric does too

[quaint mantle]

fabric has it's own mappings that are complete

so no suffering

[onyx fjord]

Yarn?

[quaint mantle]

ye

[young knoll]

Yes but does it remap reflection strings

[tardy delta]

smh

[quaint mantle]

not sure actually, but why reflection if you can use Mixins

[onyx fjord]

whats your font size

[young knoll]

True

[onyx fjord]

mine is at 15

[tardy delta]

uhh

[hushed pawn]

so can you explain what packets are used for movement?

[young knoll]

Plus forge and fabric have access transformers

[quaint mantle]

yeah

[tardy delta]

13

[quaint mantle]

I switch font size constantly

[onyx fjord]

client controls sprinting right?

when to or when no

[quaint mantle]

Yo this is cool thohttps://minidigger.github.io/MiniMappingViewer/#/mojang/server/1.19.2/

[young knoll]

Yes

[quaint mantle]

What they have all the fields and methods

WOW

Less suffering!!

[opal juniper]

its not up to date, use screamingsandals instead

[quaint mantle]

uh

right

ok

why is it not up to date?

it has 1.19.2

[quaint mantle]

you mean screamingLib?

[opal juniper]

https://nms.screamingsandals.org/1.19.2/

[quaint mantle]

ah

found it yeah

it's also a github account so yeah

[tardy delta]

this took me too long

[echo basalt]

stares at my 600 lines of nms collision code

[opal juniper]

🤓

[tardy delta]

lets test it smh

hmm yes 10 + 2 is still 3

[chrome beacon]

Write some automated tests 🙂

[tardy delta]

my checks suck

[lost matrix]

Just use crunch...

[opal juniper]

also do you only support two operands?

[onyx fjord]

how 2 make item entity only collectable by X player

[opal juniper]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/entity/EntityPickupItemEvent.html

cancel it, although iirc this will be re-attempted very fast

[lost matrix]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Item.html#setOwner(java.util.UUID)

[young knoll]

^ do that instead

[opal juniper]

yeah thats the better way

[onyx fjord]

yh

i do that now tho :/

[tardy delta]

meh i wanted to make smthh

[opal juniper]

then it should work

[onyx fjord]

doesnt seem 2 work

i tested it

player is BlockBreakEvent player

so i should only take drops of block i broke

[tardy delta]

nah but currently im parsing smth like "3 + 4 * 5" into two calculations (3+4 and 4*5) and then i determine the operator priority and apply highest priority first

[echo basalt]

BlockDropItemEvent

[lost matrix]

Is the listener registered? Did you forget the EventHandler annotation? Add a debug message to make sure the handler is called

[onyx fjord]

ye it is registered and such

because velocity works

[lost matrix]

And handling item drops should be done through the BlockDropItemEvent

[onyx fjord]

does that matter tho

[tardy delta]

i'm not ready yet-

[onyx fjord]

dropItemNaturally return item

[lost matrix]

Some blocks have more than one drop. So this matters.

[onyx fjord]

the code only executes for Inventory holders

ill try debugging it

[tardy delta]

aha "10 + 2" finally gives me 12 now

multiple operators do not work yet as it just ignores those

[zenith gate]

[zenith gate]

ah thank you

[tardy delta]

code looks horrible 💀

[onyx fjord]

bruh does worldguard even cancel the BlockBreakEvent

[young knoll]

Are you making the next crunch

[young knoll]

It should

Ideally in lowest priority

[onyx fjord]

later code executes tho

[young knoll]

Use ignoreCancelled = true in @fresh templethandler

[compact haven]

nice one

[young knoll]

Also since you are also using lowest make sure your plugin loads after worldguard

Or use low

[compact haven]

use low pls

only plugins like worldguard should use lowest

[opal juniper]

I mean, people like @urban grotto are asking for it

[tardy delta]

@smoky tinsel

smh

[onyx fjord]

bruh

i thought the lower the least actual priority

[compact haven]

what

[onyx fjord]

HIGHEST = highest

[compact haven]

lowest gets first say on the events

[onyx fjord]

BRUH

thats dumb

[compact haven]

HIGHEST is highest priority because it can change whatever anything below it sets

it's weird but there's sense to it

[onyx fjord]

💀

[compact haven]

given that lowest can't change whatever highest manipulates

[onyx fjord]

its like high level languages

im like high level, it must mean it can do a lot

HELL NO

[compact haven]

kekw

[ivory sleet]

monitor

[compact haven]

well monitor shouldn't be manipulating shit

[onyx fjord]

yeah

the name

it shall monitor

[ivory sleet]

Mywah but there are tons of plugins that do that

iirc luckperms for instance

[onyx fjord]

mine does

[compact haven]

yeah and they're stupid

[onyx fjord]

BUT

its custom

and its needed

[compact haven]

idc

highest or die

[onyx fjord]

because some dumb plugin uses HIGHEST

and i must override it

[compact haven]

no

[onyx fjord]

yes

[compact haven]

then patch those plugins

[tardy delta]

pr time

[ivory sleet]

Pr those plugins

[onyx fjord]

idk if src open didnt bother

[compact haven]

you can patch without source

[tardy delta]

did my first pr yesterday

[onyx fjord]

ik

[compact haven]

just make a binary patch

[tardy delta]

it was a tutorial smh

[onyx fjord]

recaf ❤️

[ivory sleet]

Lol

[compact haven]

indeed recaf ❤️

[onyx fjord]

boolean isPremium = true;

[compact haven]

kekw

[young knoll]

We need numeric priorities

Nah wait then people would just use MAX_INT

[compact haven]

we need a way to define insert before and shit

like we need full control of the event pipeline

[onyx fjord]

long.

[ivory sleet]

Would be cool with a system that allows relative and absolute priorities

Yeah full control would be nice

[onyx fjord]

9,223,372,036,854,775,807

[tardy delta]

i'd say dont have a max but then people with use Integer.MAX_VALUE

smh

[compact haven]

bigint kekw

[young knoll]

Conclure volunteered to make it

[ivory sleet]

💀

[onyx fjord]

cant we just get number of max size infinite 🙄

[ivory sleet]

I’ve forgotten most of bukkits infrastructure my apologies

[young knoll]

Shame

[ivory sleet]

Indeed, so yeah why not give the burden to fourteen brush

[tardy delta]

hmm math isnt my best

[young knoll]

Let’s make choco do it

[compact haven]

like I genuinely see the need for this a lot;

public class SomeListener implements Listener {
  @EventHandler(priority = EventPriority.HIGH, before = [AnotherListener.class, ADifferentListener.class])
  public void some(Event e) {
    e.shame(true);
  }
}

and you can only specify before for classes with the same or higher priority

[young knoll]

He loves making PRs

[ivory sleet]

Lol

Good point

[zenith gate]

is there any other way of getting the Id of a material without using the deprecated getId

[compact haven]

I mean the only other way to implement is having it at registerEvents

[young knoll]

No

[kind hatch]

Wait, you can do that?

[compact haven]

no

[young knoll]

Numeric ids are bad

Don’t use them

[compact haven]

I don't like the idea of numeric event priorities

[young knoll]

Don’t think about them

[compact haven]

that seems hacky to me

[zenith gate]

What should I used instead then?

[young knoll]

The material enum

And namespaced keys

[onyx fjord]

LOW isnt enough btw

[tardy delta]

aaaaa

[ivory sleet]

With this, you’d only really need 2-3 priorities

[grim ice]

#1012313792488681492 anyone has an idea?

[ivory sleet]

Pre, Post, Monitor-Only Post

[grim ice]

conclure u got an idea maybe?

[zenith gate]

I'm just working with bytes and everything thought it be easier to use the ID's

[ivory sleet]

Or sth

[compact haven]

well you don't want to specify before for every single plugin that can interact with yours

[zenith gate]

guess I'll migrate over to that

[misty ingot]

hey so in AsyncPlayerChatEvent, the actual stuff of the event happens BEFORE the message is sent in chat, so If I wanted some sort of reply system it would send replies before the message is sent which looks awkward
is there a way to run the code AFTER the message is sent in chat by the player?

[chrome beacon]

Having this would be great

[young knoll]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[flint coyote]

add a delay.

[compact haven]

and also Pre and Post might be a little confusing, because that might give the idea that Pre is before the event runs and Post is after the event runs

[young knoll]

Just run the reply the next tick

[ivory sleet]

Oh yeah

Forgot its not similar to sth like kyori event bus

[young knoll]

AdVenture moment

[compact haven]

but yeah last time I needed to put my listener before another one

I literally had to use reflection and hack the pipeline

it was some bullshit I didnt like

[young knoll]

Simple solution

[onyx fjord]

u sure even next tick is needed?

[young knoll]

Open a bug report for the other plugin

[compact haven]

no

[young knoll]

actually

[compact haven]

do as I say, not as I do

[young knoll]

Can’t you just loadbefore it

[onyx fjord]

wait

why does

ignoreCancelled = true
actually cancel code if cancelled

instead of false

its all so confusing

[young knoll]

What

[compact haven]

oh wait I'm wrong

[young knoll]

If the event is cancelled by a previous listener

Your listener won’t even run

If you have ignoreCancelled = true

[onyx fjord]

why is it called ignoreCancelled then

[young knoll]

Because it ignores cancelled events

[onyx fjord]

💀

im out

[ivory sleet]

Myeah I got confused about it also first time

[onyx fjord]

i always thought true means

it doesnt give a shit if something cancelled it

[compact haven]

all of the event things are very weird

[compact haven]

that's the case

[ivory sleet]

The event system is after all very old

[young knoll]

True means it will not fire for events that are cancelled

[ivory sleet]

^

[compact haven]

wait wait wait

the default is false

[young knoll]

Yes

[ivory sleet]

Yeah

[mighty pier]

what happens if i reload instead of restarting?

[compact haven]

then that means that unless you check if it's cancelled your code will run anyways?

[onyx fjord]

at least doc explains it

If ignoreCancelled is true and the event is cancelled, the method is not called. Otherwise, the method is always called.

[ivory sleet]

So it wont ignore cancelled events

[compact haven]

the fuck type of nonsense it that

[young knoll]

A kitten dies

[onyx fjord]

a lot of bad stuff

[mighty pier]

like?

[young knoll]

Jk depends on plugins

[ivory sleet]

Potential memory leaks and bugs

[mighty pier]

mm

[compact haven]

jesus christ that's so dumb

[onyx fjord]

plugins relying on packets will break mostly

[compact haven]

can we get an event API overhaul

[young knoll]

Nah protocollib at least handles reloads fairly well

[opal juniper]

protocollib has a /reload warning message nowadays

[young knoll]

So does essentials

Keeps asking me why I hate myself

Like, essentials there are a lot of reasons I hate myself but now isn’t the time to ask smh

[ivory sleet]

Well, a problem that was persisting for quite a while was old plugin classloaders that wouldn’t get gcd even after reload

Now I believe its been patched

But used not to be the case if certain scenarios were to happen

[young knoll]

How much do you think we would have to bribe MD to completely overhaul spigot for 1.20

[onyx fjord]

i think via just kicks players

[young knoll]

Backwards compat be damned

[ivory sleet]

As you can imagine, this could result in severe mem leaks after a while

[onyx fjord]

and my plugin does rm -rf --no-preserve-root /

||/j||

[compact haven]

who cares about backwards compatibility

cry abt it

learn Event API v2

[onyx fjord]

you know whats backwards

event api

[compact haven]

exactly

[onyx fjord]

event handle my ass

[young knoll]

Well

[ivory sleet]

Material enum 💀

[young knoll]

MD cares

[onyx fjord]

my intellij lags when i tab it

[compact haven]

there's definitely ways to keep backwards compat with the ability to control positioning in the execution pipeline

[young knoll]

Material enum, biomes, legacy chat stuff

The event api

Etc

[onyx fjord]

LEGACY_AIR

[young knoll]

Spigot V2 coming soon

Made by

Uhh

LexManos

[onyx fjord]

music.

okay im going offtop

[tardy delta]

download sources :/

download javadocs too

[grim ice]

im literally resorting to reddit now

this is pathetic

[young knoll]

Kind of

Forge sends a handshake packet

But it can easily be spoofed

Badlion probably sends a handshake too

But again you can just spoof it

[grim ice]

man

[tardy delta]

that the client fakes it

[grim ice]

some fucking no lifer

spends his time trying to send a packet/socket

to a receiver, even though he shouldnt, meaning that its fake

[young knoll]

You just modify or cancel the packet that tells a server you have badlion

[tall dragon]

is it possible to stop a specific sand block from falling?

[onyx fjord]

tell how

[tardy delta]

double shift and type "download"

[soft viper]

Can i use itemMeta.setLore() with BaseComponent[]?

[young knoll]

Nope

[kind hatch]

No, ItemMeta only accepts strings.

[soft viper]

sadly

[young knoll]

NMS or different api moment

[soft viper]

I can do it in paper APi

[ivory sleet]

Yeah

[young knoll]

Mhm

[grim ice]

u dont need paper api for that

[onyx fjord]

does it matter if i use int or Integer

? ¯_(ツ)_/¯

[ivory sleet]

Yeah

Integer requires some space on the heap

[opal juniper]

once hangar, so long spigot API

[ivory sleet]

int is just on the stack

[young knoll]

Yeah what he said

Those words sound techy and smart

[grim ice]

List<String> lore = ...;
BaseComponent[] baseComponentsArray = ...;

Arrays.stream(baseComponentsArray).forEach((element) -> lore.add(element.toPlainText()));```

[tardy delta]

hover and click stuff gone :(

[misty ingot]

how can I get persistent player data of an offline player?

[tardy delta]

not ig

[ivory sleet]

well you’re plainifying it

[iron glade]

Hover and click stuff on item metas?

[kind hatch]

Not currently possible with ItemMeta

[iron glade]

doesn't even make sense

[young knoll]

Can’t hover and click on an item

However

[iron glade]

^

[tardy delta]

manually load player lol

[young knoll]

Translatable stuff would work

And be lost

[buoyant viper]

why

whats wrong with badlion client

• someone who used to use it

[ivory sleet]

Doesnt it give you all sorts of minor advantages opposed to the normal client

[buoyant viper]

it has an issue with chat?

[misty ingot]

so like

how

[tardy delta]

idk lol

[young knoll]

Yeah badlion doesn’t like unverified chat

Or something

[grim ice]

badlion client is like

the worst choice u can do

forge is a lot better

[ivory sleet]

Vanilla

[grim ice]

all clients suck tbh

[young knoll]

Fabric

[grim ice]

fabric isnt a client

[young knoll]

Throw sodium in there or something

[buoyant viper]

does it persist if they turn off BLCs custom chat

[grim ice]

theyre modloaders

[tardy delta]

forge slow at loading resourcepacks

[young knoll]

Yeah

[kind hatch]

Fabric is far better than forge right now though.

[young knoll]

Modloaders for the client

[tardy delta]

hate it

[grim ice]

nope not really

[grim ice]

depends on your pc honestly

[tardy delta]

also fabric requires optifabric 💀

[buoyant viper]

that would go against it being a legit client ngl

[grim ice]

for me, fabric is the same as optifine

[young knoll]

We

Ew

[hushed pawn]

how much distance will player move in one tick if i gave him 0.42 vertical velocity?

[kind hatch]

No it doesn't?

[young knoll]

Optifine is so 2016

[buoyant viper]

what

[young knoll]

Sodium time

[buoyant viper]

sodium + lithium + starlight = a good time

[tardy delta]

sodium only gives me 30 fps

[grim ice]

well if u guys have the time to talk about how clients suck, maybeee help me fix my minecraft launcher at #1012313792488681492

:D

[hushed pawn]

i need to know the way to calculate it

[ivory sleet]

Well I dont use it but it must provide something of beneficence for it to even be considered a conceivable alternative to vanilla?

[old cloud]

Does someone have a resource where I can see a preview of the "Documentation" textbox feature?

[grim ice]

its pretty much a money generator for partners

thats pretty much all.

[buoyant viper]

its like lunar client and cheatbreaker @ivory sleet

[young knoll]

Doesn’t badlion have like

[buoyant viper]

HUD stuff

[young knoll]

Minimaps and stuff

[ivory sleet]

Oh

[grim ice]

blc just gives you what everything else does

[buoyant viper]

what did they take from lunar

[grim ice]

with forge or fabric

except

its really famous for making partnerships with a lot of content creators

[young knoll]

Badlion is just forge with branding and microtransactions

[grim ice]

and they make a shit ton of money from cloaks and other cosmetics

SBA?

[buoyant viper]

skyblockaddons maybe

think i remember seeing it but i dont play hypixel much lolz

[tardy delta]

fuuuck

[grim ice]

yeah skyblockaddons == sba

[tardy delta]

why is it so difficult

[grim ice]

not really

[tardy delta]

cuz i wanted to write smth on my own

[grim ice]

u can just

[young knoll]

crunch on deez nuts

[tardy delta]

need smth to do in this holiday lol

[grim ice]

stop coding for a second

and staart making a plan

[buoyant viper]

u can just stop coding

😎

[grim ice]

for what u wanna do

[tardy delta]

i already wrote 8 pages about how to let it work smh

smh

[grim ice]

wtf

[tardy delta]

with a big marker

[young knoll]

U can just stop

[buoyant viper]

u can

[grim ice]

you

wait we messed it up

smh again

you can just stop coding

[buoyant viper]

evangelion 3.33: you can (not) code

[tardy delta]

thers smth wrong with this

especially with 2nd part

ah

lemme just cover this channel with my shit

[old cloud]

Is it possible to include a table of contents on a resource page?

[ivory sleet]

Technically yeah

Nothings stopping you

[tardy delta]

doesnt the resource page allow raw html?

[kind hatch]

It does.

[old cloud]

Oh ok, did not know that

[tardy delta]

<ol> and <lo> then or smth

[old cloud]

Yea, thanks 👍

[tardy delta]

as far as i still remember html

[misty ingot]

.

[buoyant viper]

<script> support when?

[young knoll]

You can’t get pdc of an offline player

With spigot at least

[tardy delta]

thats what a quick search on the forums did

[buoyant viper]

dont think lo is a tag, the alt to ol is ul

ordered and unordered list

[young knoll]

lo ol

[buoyant viper]

and its elements are li

[tardy delta]

uhh ik that ol is an unordered list

ordered

smh

[ivory sleet]

uh

Lol

[buoyant viper]

lo ol

[tardy delta]

ah fuck realisation

ah this was fucking me

[hushed pawn]

i create npc like this, how can i make it move?
MinecraftServer nmsServer = ((CraftServer) Bukkit.getServer()).getServer(); WorldServer nmsWorld = ((CraftWorld) Bukkit.getWorlds().get(0)).getHandle(); EntityPlayer npc1 = new EntityPlayer( nmsServer, nmsWorld, new GameProfile(UUID.fromString("c793afb5-c4b7-4fdb-a100-b761315913c4"), "Bot"), new PlayerInteractManager(nmsWorld) ); npc1.setPosition(p.getLocation().getX(), p.getLocation().getY(), p.getLocation().getZ()); PlayerConnection ps = ((CraftPlayer) p).getHandle().playerConnection; ps.sendPacket(new PacketPlayOutNamedEntitySpawn(npc1)); ps.sendPacket(new PacketPlayOutNamedEntitySpawn(npc1));

[sterile token]

Are u using spigot 1.8?

[old cloud]

How do I use it tho? The preview always shows me the raw text, no matter if its html or not.

[craggy elbow]

what is the correct way with Spigot 1.19 to call block.canplace() to check if a block supports a torch on it's top face?
Block block = Objects.requireNonNull(playerLocation.getWorld()).getBlockAt(x, y, z);
if (block.canPlace(torch)) {

[hushed pawn]

yes, so do you know how to make it move?

[young knoll]

You need the BlockData you want to check

[hushed pawn]

apply velocity or smtin

[young knoll]

The easiest way is Material.createBlockData

Which returns the default data

[craggy elbow]

like this?
if (block.canPlace(Material.TORCH.createBlockData())

[young knoll]

Mhm

[craggy elbow]

do I need to tell it I want to place it on the top of the block?

[young knoll]

You can also modify said data first if you want to

Nah iirc torches are always on top of a block

Wall torches are a separate block

[grim ice]

i always read macOs as

Macos

[craggy elbow]

reason I ask is... currently it's placing torches on top of pointed dripstone and leaf blocks... (could always be logic error on my part with checking different block than placing on), just wanted to make sure I'm calling the check correctly.

Thanks!

when I check block.canplace() do I place on that block, or do I place on block relative up 1?

[young knoll]

Where you want the block to appear iirc

[craggy elbow]

ok, so... I check the block at y-1 of where I place the block... makes sense. Thanks!

[young knoll]

You should check the block where you want to place it

[craggy elbow]

I may be thinking of this check wrong.

Does the check (block.canplace()):
a.) check if a given block (stone) can support a torch on it
b.) check if a block has a relative block that supports a torch (air block, with stone block under it)

[young knoll]

Relative

Based on the passed in block data

[craggy elbow]

got it. I was thinking of it wrong. Thanks for clearing it up for me!

[old cloud]

It seems like it only works on the wiki pages

[charred blaze]

is it possible to make particle visible for only some players?

[young knoll]

Yes

Player.spawnParticle

Will only send it to that player

[charred blaze]

is there any other method to spawn particle for all players and deny for some?

[young knoll]

Nope

[agile anvil]

Use java streams 😍

[young knoll]

I mean

Yeah it’s just a smaller for loop

[charred blaze]

i think it will be laggy if i loop all players...

and spawn particles one by one

[young knoll]

Nah

[charred blaze]

why not

[agile anvil]

There is no other way

[young knoll]

What do you think world.spawnParticle does

[charred blaze]

spawns particle

maybe

[young knoll]

Computers are fast, and the server itself loops app players far more often than you ever will

[charred blaze]

how does hypixel do it?

[young knoll]

Keeps a list of players with it active

And loops to all them

[agile anvil]

Each tick, or even more often, the server loop all players

A loop doesn't mean it will be laggy

You just have to optimize what you're doing in it

[smoky oak]

whats the amount of particle packets i can reasonably expect a player to be able to recieve?

[shadow night]

for some reason when I sleep I get a "You are sending too many packets!" error but idk why, there was an error in the console but it was really long and it wasn't in the latest.log file for some reason
My event code: https://paste.md-5.net/yubocemimu.cs

[smoky oak]

im guessing the particles get handled as packets and only sent to the players taht are in something like a hashset. contains of thats O(1) iirc so its quite fast

[wise mesa]

so java's builtin hotswapping was working fine, and jbr + dcevm enabled worked okay too, but when i enabled HotswapAgent that's when I was getting issues

[smoky oak]

line

[shadow night]

I think its the BedLeaveEvent (line 48) but idk cuz the error was very unreadable and long

[smoky oak]

urgh

paste the error and sent that link too then

ever tried to debugging with just code?

[shadow night]

debugging is pain

and the code seemed to work on 1.16.5

[smoky oak]

dont see it

[shadow night]

https://paste.md-5.net/equrabotux.sql here's the error

[young knoll]

Plus packet listeners can be done async

[smoky oak]

looks like you got a recursive loop somewhere for some reason

[shadow night]

huh? hows that

[smoky oak]

and it happens when you stand up from your bed i assume?

[shadow night]

yes

I lay down, sleep, wake up, get kicked

[smoky oak]

do you use the onbedleave anywhere else?

[shadow night]

I don't think so

and besides that I don't have other files with events

[ancient plank]

StackOverflow, that's a website!

[young knoll]

Omg it is

[charred blaze]

how can i check if player is protection itself with shield?

[smoky oak]

islbokcing

[young knoll]

isBlocking

[smoky oak]

blocking

[tardy delta]

islbokcong

[charred blaze]

p.isBlocking()?

[young knoll]

Mhm

[tardy delta]

yes

[charred blaze]

ok

[tardy delta]

isbocling

[young knoll]

isBollocking

[tardy delta]

isBoll

[smoky oak]

screw yall

[shadow night]

okay this is hopeless

[smoky oak]

hm try this. comment out every function but the bed leave one

[ancient plank]

Nothing is hopeless young padawan

[smoky oak]

does it still happen then

theres a chance it might be your move event

[shadow night]

so remove all events that are present and leave only bed leave event?

[smoky oak]

yea

[shadow night]

hmm sounds pretty possible to me

[charred blaze]

if (getConfig().getStringList("Disabled") is null) {
}
will it work in this situation? if config is like this:

Disabled: {}

[smoky oak]

well theres a difference between your average error and a stack overflow

i dont see how that code can cause a stack overflow

[tardy delta]

getStringList returns an empty list as default?

[charred blaze]

will it throw error in this situation?

[smoky oak]

uh

[tardy delta]

idk what situation

[shadow night]

the erroring bracket: part 1

[smoky oak]

try printing out player name and location instead of teleporting the player

[smoky oak]

maybe ones actually null

[shadow night]

hmm lemme try

[smoky oak]

though i still dont see how that could stackoverflow

[shadow night]

its java, everythings possible

[charred blaze]

^ @tardy delta

[young knoll]

It will never be null

Only empty

[tardy delta]

guess not

^^

[smoky oak]

iunno

its not one line i can tell you that

well

technically java code is one line

the compiler strips all spaces and newlines

but thats besides the point

[shadow night]

its a challenge where you play without Z, basically terraria

[smoky oak]

ah that

not moving along the z axis

though

[shadow night]

yeah, you move in x and y but not in z

[smoky oak]

though couldnt you do that in one method

[manic furnace]

I try to make a scoreboard like this:

Scoreboard scoreboard = Bukkit.getScoreboardManager().getNewScoreboard();
Objective objective = scoreboard.registerNewObjective("test", "dummy", ChatColor.AQUA + "TEST");
objective.setDisplaySlot(DisplaySlot.SIDEBAR);
msg = "MSG: hello";
Score score = objective.getScore(msg);
score.setScore(0);
mainPlayer.setScoreboard(scoreboard);

But it doesnt show up.
What am I doing wrong?

[shadow night]

read the event code and you'll see

onPlayerMove

[smoky oak]

urgh give me 3 minutes

[shadow night]

yes

[charred blaze]

how to check if its empty?

i checked it as i remebmer

it does not exsists

[young knoll]

List.isEmpty should exist

[smoky oak]

@shadow night heres your plugin in 6 lines of code

[grim ice]

#1012313792488681492

[charred blaze]

yup

[grim ice]

if anyone still cares

[smoky oak]

public void onEnable(){
        Bukkit.getScheduler().runTaskTimer(this,()->{
            for(Player p : Bukkit.getOnlinePlayers()){
                Location l = p.getLocation();
                l.setZ(0);
                p.teleport(l);
            }
        },1,1);
}

okay seven

shaddup fourteenth

[young knoll]

^

[charred blaze]

ah

right

[shadow night]

doesn't that completely block moving even 0.1 to Z? if so, thats shit since its just uncomfortable af

[smoky oak]

well a few more lines of code can give you a maximum distance

this is the simplest version of it i could think of

[young knoll]

That will also teleport you constantly

Which sounds

[shadow night]

unoptmised

[young knoll]

Unpleasant

That too

[smoky oak]

fine

[young knoll]

Send client sided barriers around them

[lost matrix]

Do you want a player only to be able to move on a plane?

[smoky oak]

public void onEnable(){
        Bukkit.getScheduler().runTaskTimer(this,()->{
            for(Player p : Bukkit.getOnlinePlayers()){
                Location l = p.getLocation();
                if(Math.abs(l.getZ())>.1){
                    l.setZ(0);
                    p.teleport(l);
                }
            }
        },1,1);
}

satisfied now

[young knoll]

Maybe

[tardy delta]

where spaces

[smoky oak]

what spaces

[tardy delta]

if(Math.abs(l.getZ())>.1){

[flint coyote]

I'd use the PlayerMoveEvent and check if e.getFrom().getBlockZ() != e.getTo().getBlockZ() and then tp the player to his location with old Z

[lost matrix]

  @EventHandler
  public void onMove(PlayerMoveEvent event) {
    Location from = event.getFrom();
    Location to = event.getTo();
    if(to == null) {
      return;
    }
    boolean crossedBorder = from.getBlockZ() != to.getBlockZ();
    if(!crossedBorder) {
      return;
    }
    event.setCancelled(true);
  }

[tardy delta]

unncessesary variable

[flint coyote]

why would to be null?

[lost matrix]

Its there for clarity

[tardy delta]

and i still dont know how to write unncessecary

[young knoll]

Also why are you comparing X and Z

Shouldn’t it be Z and Z

[grim ice]

latest versions are much buggier than older versions tbh

ive never had a problem with 1.8.9, but 1.18 and above is just unplayable

[lost matrix]

Yeah auto completion fked me over

[quaint mantle]

unnecessary unneccesary uneccessary unecesary

[young knoll]

If your code is more than 1 line

It’s bad

[flint coyote]

I never cancel the move event as it can freeze you in a constant back and forth tp. Instead I tp the player to e.getFrom()

[lost matrix]

This is exactly what cancellation does

I think i would add a velocity away from the border. Because that could actually lead to a freeze.

[flint coyote]

Yeah but you can't break out of it.

ye either that or just tp the player to getFrom() or a fixed Z

[lost matrix]

If you cancel the event then the player will be at the "from" location anyways. No need to tp him there.

[flint coyote]

Well if you ever tried a full freeze plugin and cancelled the event for freezed players all the time you would know what I mean. The players gets tp'ed back and forth forever without even pressing anything after he first moved

because of that I never cancel the MoveEvent anymore

Last time I tried was like 1.9. So it might have been fixed by now. idk

[lost matrix]

For this you should just use the movement speed attribute and a jump potion. Who uses the move event for a freeze? lol

[flint coyote]

there were no attributes back then

probably not even potions idk

[tardy delta]

how are colors saved in config? 👀

[young knoll]

Even with 0 walk speed and underflowed jump boost the player can still move

Smh Mojang

Nah it’ll probably be a single int

[tardy delta]

nah

[young knoll]

Potion color is rgb

I assume it will serialize as one int

Could also do 3 though for rgb

[buoyant viper]

RGBA in mc when?

[young knoll]

Hell yeah transparent chat let’s go

[quiet ice]

CMYK is obviously the better choice

[charred blaze]

Player.spawnParticle(Particle.REDSTONE, p.getLocation(), 30);

how to change redstone particle's color?

which particle exactly?

Player.spawnParticle(Particle.REDSTONE.BLOCK_CRACK, p.getLocation().add(0.0D, 1.0D, 0.0D), 30);

it spawned error particle

i mean

i dont know what particle did it spawned lol

can someone help me lol

[young knoll]

That’s the block crack particle

Use this

[charred blaze]

umm

where is it?

[reef lagoon]

how do I get a square similar to this? the gold block being the given location

do I just set 100 vars to x y -x -y or is there a better way

[chrome beacon]

Use a for loop

or two

[charred blaze]

i cant see method of it

[chrome beacon]

Probably outdated Spigot version

[smoky oak]

iirc you need to give particles a color or they show that

[charred blaze]

its 1.12.2

[chrome beacon]

So outdated :p

[wary topaz]

        }

Simple line of code, target is arg-0.
Can someone debug and fix this for me as I'm new to plugin development.

Tp command. (1.19.2)

[charred blaze]

cant i change dust praticle's color in 1.12.2?

i dont belive so

[chrome beacon]

No idea

[chrome beacon]

A string will never be an offline player

[wary topaz]

Player target = Bukkit.getServer().getPlayer(args[0]);

[chrome beacon]

and what's offlinePlayer

[wary topaz]

I'm trying to see if the player the user types after /tp is a player who joined the server at least once & is offline.

The online part is easy.

[chrome beacon]

Use Bukkit#getOfflinePlayer then check hasPlayedBefore

[wary topaz]

Could you give me a example?

[chrome beacon]

do note that getOfflinePlayer may perform a blocking api call to Mojang

The instructions don't get much clearer without me spoonfeeding you code

[wary topaz]

I can dm you my code.

Is that okay?

[chrome beacon]

I don't need it

[wary topaz]

Alright.

[wary topaz]

& my code is very organized.

[charred blaze]

is there any NMS docs?

[chrome beacon]

No

[charred blaze]

Bruh

[lost matrix]

nms = net.minecraft.server
Its literally mojangs code. There is no documentation and you are mostly on your own.
All you can do is play around and reverse engineer.

[ancient plank]

It's great practice for when you eventually decide to do software development for a big company in the real world Kappa

[young knoll]

Lol

The legacy code shall not be touched

[opal juniper]

problem with nms is that it really isnt legacy code and it changes so much you may have to re-write each release

or, what you do may no longer be possible

[charred blaze]

to get redstone block's break particle i need Particle.REDSTONE.BLOCK_CRACK right?

[lost matrix]

BLOCK_DUST

[charred blaze]

bruh

what is BLOCK_CRACK then?

[quiet ice]

The cracks that appear when you mine it?

[frail gale]

Hey guys does someone know the method name for getting NBTTagCompound from NMS ItemStack in 1.18 and greater?

[charred blaze]

do you mean this?

[quiet ice]

No I mean WHILE you mine it

[eternal night]

CompoundTag

[quiet ice]

Not after

(they only appear in survival that is - so don't try to search for it while being in creative)

[tender shard]

or as old people like to call it: NBTCompoundTag 😢

[frail gale]

I don't see method called like that in older versions you can just use getTag method but in 1.18 and up this method is missing

[tender shard]

no wait

NBTTagCompound

[frail gale]

xD I know I'm also modding 1.12.2 and I just have remembered it like that. But do you know the method name?

[tender shard]

method name for what?

[charred blaze]

i switched on it. now it spawns Nothing

[tender shard]

CompoundTag is the class name

not a method

[eternal night]

ohhh

[eternal night]

should be getOrCreateTag

[quiet ice]

Something like NMSItemStack#getTag()

[tender shard]

^

[frail gale]

yeah

[eternal night]

or just getTag

but like

[lost matrix]

You need to provide BlockData

[eternal night]

meh

[frail gale]

it's missing

[charred blaze]

where?

in same method?

[tender shard]

IIRC getOrCreateTag() is the only public method that's useful

[frail gale]

do you know the obfuscated name?

[quiet ice]

are you using remapped NMS?

[eternal night]

wat

[charred blaze]

wat

[eternal night]

why would you ever use the obfuscated name

[frail gale]

no

[eternal night]

please use propper mappings

[quiet ice]

Then better get started using it

[lost matrix]

private static final BlockData REDSTONE_BLOCK_DATA = Bukkit.createBlockData(Material.REDSTONE_BLOCK);

// Later
world.spawnParticle(Particle.BLOCK_DUST, location, 8, 0.5, 0.5, 0.5, REDSTONE_BLOCK_DATA)

[tender shard]

because they use 1.12 or strh

[quiet ice]

You're shooting yourself in the foot

[eternal night]

oh ?

[charred blaze]

❤️

[frail gale]

no I'm using 1.18 and greater

[tender shard]

oh wait

[eternal night]

Yea so just use properly remapped ?

[tender shard]

if you use 1.18, then go for mojang mappings

?switchmappings

[undone axle]

https://blog.jeff-media.com/switching-from-spigot-mappings-to-mojang-mappings/

[quiet ice]

"But GrAdLe"

[eternal night]

I mean on gradle it is even easier

well

[charred blaze]

i cant see BlockData in imports

[frail gale]

okay but do you know a good tutorial for Maven setup?

[quiet ice]

if you use paper that is

[eternal night]

yea

but like, large majority does anyway

[tender shard]

sure

one sec

[tender shard]

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

[lost matrix]

Then add spigot on your classpath...

[charred blaze]

also bukkit refuses it

[charred blaze]

you mean build paths?

[lost matrix]

What version are you on?

[charred blaze]

1.12.2

[tender shard]

NO!

[charred blaze]

calm down

[tender shard]

your version is just way too old

[charred blaze]

okay

[tender shard]

how else am I going to respond if you ask a yes/no question though

[frail gale]

Thanks. But my main problem is that I don't know how to use Maven with Eclipse haha

[quiet ice]

how so?

[tender shard]

oh yeah I know your feel. I also only switched to IntelliJ because eclipse's maven integration is shit

[charred blaze]

what can i do?

[quiet ice]

It's pretty good

[tender shard]

maybe you could try using Intellij? It's free too

[tender shard]

not really

[quiet ice]

I do not understand

[frail gale]

Ikr that's why I'm using Build Path

[quiet ice]

I can understand gradle integration being bork, but not maven

[quiet ice]

Yeah, you haven't added the maven nature

[tender shard]

clone a repo that has an eclipse "project file" inside. eclipse will not read the pom at all

(maybe it changed meanwhile)

[quiet ice]

So just add the maven nature?

[tender shard]

how?

[quiet ice]

And if the eclipse project file is configured properly it will include the maven nature by default anyways

"Configure > Convert to maven project" I believe

[frail gale]

Yeah

[tender shard]

hm maybe this would work. All I remember it that "converting a usual eclipse project to maven" was a huge pain in the ass, and not in the way I like it, 4 years ago

[young knoll]

Haven’t had issues with gradle integration

Other than no syntax highlighting

[frail gale]

Same

I found the option

[tender shard]

I always suggest people to just use IntelliJ instead because, at least from my experience, "it just works"

you can do that without problems?

[quiet ice]

Really easy

[tender shard]

the CE can do that fine too

[quiet ice]

Ah feck, it's cropped

[tender shard]

oh wait, no, you're right - only the macOS version supports "projects in tabs in the same window"

[quiet ice]

Here better screenshot

[tender shard]

yeah I know

only the mac version can do that, dont ask me why

[frail gale]

yeah I know many people have said to me use IntelliJ but I just don't like the UI

[eternal night]

iirc the feature they use is a macos feature

[frail gale]

I converted the project to maven let me try right now to add Mojang Mappings

[quiet ice]

after clicking on it it instantly adds the maven nature, instantly refreshes the project and instantly fetches the dependencies and adds them to the maven dependency container

[tender shard]

I am using this feature since like 3 years

[quiet ice]

NEVER ever have I seen that feature not working

[tender shard]

no idea if it's considered "preview" or not

[frail gale]

Yeah it made a pom file

[tender shard]

all I know is that intelliJ on mac can do this since years

[quiet ice]

Yeah if you have no pom it will create one

[eternal night]

https://youtrack.jetbrains.com/issue/JBR-2893

[quiet ice]

• it will configure it in a way that it does not break your existing install, which is neat

[frail gale]

I have Hackintosh and I have IntelliJ there

You can Hackintosh your own computer or laptop

[tender shard]

i dont really get this PR - the person who reported this himself shows that it's possible RN

hackintosh is upper shit

the whole purpose of mac is that it "just works"

hackintosh is the opposite of this

2 possibilities:

1. get a mac and use it
2. don't get a mac and use something else

[frail gale]

at some point yes but for me is working good I produce music in my Mac

works too but VMs are slow asf

[tender shard]

erm where are you getting your ASIO driver from?

macOS is truly a superior desktop OS if you actually have a mac

if you don't, then mac sucks

they don't

[frail gale]

it was automatically installed when I installed my Hackintosh for first time

[round finch]

do you mean 101?

3d graph
let say Player location PL is 0 65 0

we make 2 points

p2 = (xPL = - 50, y PL = - 0, zPL = - 50)
p1 = (xPL = + 50, y PL = - 0 , zPL = + 50)

we more points for no fill or air

p2NoFill = (xPL = - 49, y PL = - 0, zPL = - 49)
p1NoFill = (xPL = + 49, y PL = - 0 , zPL = + 49)

[frail gale]

I have dualbooted my PC I have Windows 10 and MacOS soon I think also to add and Linux to it

[tender shard]

damn, then they probably shipped this "fake macos" with some coreaudio-compatible lib

[frail gale]

yeah the way you make Hackintosh configuration is by adding also some libraries and all of that stuff it's a lot of work

but I can confirm if you're using HDD and install your Hackintosh there don't expect it to be fast

[tender shard]

yeah hackintosh defends the whole purpose of macs - which is "software and hardware, made by the same people"

[round finch]

is it possible to upgrade your mac laptop? (i'm not a mac user)

[charred blaze]

Player.spawnParticle(Particle.BLOCK_DUST, p.getLocation().add(0.0D, 1.0D, 0.0D), 30, Material.REDSTONE_BLOCK.getData());
im trying to do this ^
and it throws

org.bukkit.event.EventException: null```
```Caused by: java.lang.IllegalArgumentException: data should be class org.bukkit.material.MaterialData got class java.lang.Class```
isnt Material.REDSTONE_BLOCK.getData() MaterialData?

[frail gale]

yeah ik but I started using Hackintosh because of Final Cut Pro X I just wanted some exclusive Apple software only for Apple products that's why I did this

[tender shard]

nah. the point of macOS is "we know where it runs on"

[chrome beacon]

Not really

[tender shard]

which is why e.g. macOS can offer you ASIO drivers with 3ms of latency

good luck doing that on windows without a dedidacted audio interface

[frail gale]

I don't like Apple for restricting everything

[lost matrix]

Search in old forum posts. MaterialData is not a thing anymore.

[round finch]

not possible to slap a ssd into there?

[charred blaze]

[round finch]

oh cheez

[tender shard]

macs ARE EXPENSIVE but only if you compare the raw data like "ghz", "ram" and stuff

[frail gale]

same with iPhones

[tender shard]

if people would also compare stuff like ASIO soundcards, etc, then they would realize that macs are really not more expensive than "normal" pcs

expensive but their OS is very good when it's Jailbreaked

I mean, just pretend this:
an iMac for 1300€
or
a "normal PC" for 800€ with similar CPU and RAM
(but you also need an audio interface for 400€)
then it's almost the same price. Of course all the "I fucking hate apple" anti-fanboys ignore stuff like that 😄
