[echo basalt]

honestly I might not even need screens

it's cool for management but I can write my own system for logging

[eternal night]

spin up vms

[echo basalt]

what about cloudnet hmm

[eternal night]

firecracker style

[echo basalt]

would cloudnet be a viable solution

docker yucky

might go with it honestly

either that or I charge 1k$ and make my own

might charge 200$ to set it up tho

[tender shard]

just hire someone to spin up those servers for you

just get a butler

[echo basalt]

lmao yeah but

no

[novel ocean]

does anyone know how to repair an item bc something has changed and you can no longer cast an ItemStack to a Damageable
and casting ItemMeta to Damageable also doesn't work

[tender shard]

you imported the wrong Damageable

[opal juniper]

ive heard you can get child labour pretty cheap

[novel ocean]

nope

[tender shard]

there is one for itemmeta and one for entities

and you can definitely cast it if it's the correct one

[novel ocean]

im using one for itemmeta

[tender shard]

what error do you get?

[novel ocean]

i dont get any errors it just doesnt work

[tender shard]

yeah that's my go to solution for many things

[novel ocean]

import org.bukkit.entity.Player;
import org.bukkit.inventory.ItemStack;
import org.bukkit.inventory.meta.Damageable;
import org.bukkit.inventory.meta.ItemMeta;

public class RepairUtils {

    public static void repairall(Player p) {
        for (ItemStack items : p.getInventory().getContents()) {
            if (items != null) {
                ItemMeta itemsMeta = items.getItemMeta();
                Damageable item = (Damageable) itemsMeta;
                item.setDamage(0);
            }
        }
        for (ItemStack items : p.getInventory().getArmorContents()) {
            if (items != null) {
                ItemMeta itemsMeta = items.getItemMeta();
                Damageable armor = (Damageable) itemsMeta;
                armor.setDamage(0);
            }
        }
    }
    public static void repairHand(Player p) {
        ItemMeta itemMeta = p.getInventory().getItemInMainHand().getItemMeta();
        Damageable handItem = (Damageable) itemMeta;
        handItem.setDamage(0);
    }
}```

[tender shard]

you also have to set back the itemmeta to the itemstack

[opal juniper]

^

[novel ocean]

omg true

[opal juniper]

yeah i really hate the whole item meta API

the whole item api honestly

• material

[novel ocean]

its ass

[opal juniper]

god i wish i could re-write bukkit

wish i was about 10 years older

[tender shard]

i also dont like it but meh, it works fine

[opal juniper]

could have been there at the inception

[tender shard]

i wish I was 10 years younger lol

[eternal night]

I mean, item meta kind of stuff is okay in terms of API itself

what it does below the hood is trash

[opal juniper]

the backing is bad

yeah

[eternal night]

Well, its def somewhere on the paper goal thingy

there is always the decision on what is better as well, ye you could keep it all as a plain wrapper around a CompoundTag

but if you use a single item a LOT parsing its contents first might be nicer

[quiet ice]

If I had been there when it started I would def. have questioned the enchantment naming scheme severely

[opal juniper]

oh yes

like i understand the want to not tie things to vanilla naming, but errrr

DIG_SPEED my ass

[eternal night]

👀

[quiet ice]

The same goes for the material API

[opal juniper]

the material enum has just gotten too big, there should have been an attempt to split it out sooner than for it to get to here where accidently opening the source might crash your IDE

[eternal night]

that PR has been around for a while xD

maybe 1.20

🙏

[quiet ice]

Having it as an enum was an okay descision at the time (do note that back then mods were almost unheard of) but at least there should been enum entries for everything, including the things with the "magic" data values

[opal juniper]

i think it was implied in the last couple of updates to not use EnumSets anymore

[tender shard]

yeah NMS has two classes, Item and block

no idea why spigot decided to mix both

and imho they should also remove all those LEGACY materials

fuck old versions

[eternal night]

breaking backwards compat 🙀

you cannot

[opal juniper]

i think that 1.20 should be the fuck it version

like just break all compat

[tender shard]

I wish md5 would just say "fuck everything prior to 1.16"

[opal juniper]

with a big commumity re-write

[vocal cloud]

Then I can add my @since :D

[eternal night]

[buoyant viper]

fuck it we ball

[tender shard]

I like this idea

[buoyant viper]

1.20 mojang adds all the mobs that lost in the mob votes

[opal juniper]

what is 1.20? i forget

[buoyant viper]

we finally get copper golem and the yellow cow

[vocal cloud]

I still have to ping md_5 about it but I'm on vacay till tomorrow

[quiet ice]

No idea, even hmod didn't do it

[eternal night]

1.20, mojang adds a bunch of packets servers can use to make cool stuff

[buoyant viper]

1.20 mojang deletes the game

[opal juniper]

well, it was bukkit no?

[tender shard]

1.20, people still use 1.8

smh

[opal juniper]

put kennytv at gunpoint to drop 1.8 for all the via* plugins

[buoyant viper]

i mean 1.8 > 1.2

[paper bone]

Minecraft 2.0 when

[buoyant viper]

[tender shard]

second thursday in october

[buoyant viper]

we already have the custom message plugin

what

[paper bone]

I think they are talking about server transfer packets

[buoyant viper]

plugin message packet there we go

thats what i meant to say

[eternal night]

I mean

[paper bone]

I wanna see via version hack their way through that

[eternal night]

gimme a proper interaction packet

give me change server packet

[buoyant viper]

just use bungee lolez

[paper bone]

Bedrock already has server change packets

[eternal night]

shitty ones

but yea

[paper bone]

If geolocation is your main concern

Then bungee won't cut it

[buoyant viper]

what can i say

[paper bone]

You need multiple bungee cords

[buoyant viper]

death to aussie pings

[paper bone]

And do DNS shenanigans

You can setup multiple bungee cords

And vaguely target players in the same region to nearby subpools

But that's overkill

It would allow for good ping though

Without server transfer packets

[tender shard]

round robin lol

funny name

[paper bone]

Not round robin

[tender shard]

what else did you mean then?

[paper bone]

Redirecting people to closest bungee cord

[tender shard]

oh that's what you meant

[paper bone]

Having multiple bungee cords all access the same pool of spigot servers

[tender shard]

I didnt read the prior chat

[paper bone]

And for the bungee to always prioritize servers closest to itself

[tender shard]

im watching "who wants to be a millionaire" and only spam my weird messages here inbetween from time to time

[paper bone]

But we're talking a 20+ dedicated machine setup for good world wide coverage

And there are no public solutions afaik

But some ANYCAST shenanigans might work

That or regional DNS

But that's beyond me atm

[river oracle]

[warm galleon]

which of the explosion types is 6 blocks in radius? explosion, explosion huge, or explosion large?

[glass mauve]

with Java Valhalla 👀 👀 👀

[tender shard]

yes mine

[dry forum]

how can i create a fallingblock using nms? using new FallingBlock it asks for a properties object, what is that and how do i make it

[hasty prawn]

Why would you want to make it using NMS?

[tender shard]

just use the API?

[dry forum]

so only 1 person sees it

what api

[tender shard]

Bukkit

[dry forum]

.

[tender shard]

ooh ok

you can still do that

[hasty prawn]

Yeah but you don't have to make an NMS entity for that do you

Just send the packet to that single person

[tender shard]

use World#spawnFallingBlock and then do Player#hideEntity for all others

[hasty prawn]

or that

[dry forum]

uhhh

id rather use nms though since im already using nms armorstands also its less laggy

id be using quite a lot of fallingnlock

[ancient plank]

Kappa

[hasty prawn]

How is it less laggy

[dry forum]

idk it just is

[ancient plank]

API isnt any slower than nms

[dry forum]

oh?

[hasty prawn]

Even if it was it would be negligible

[ancient plank]

The API is legit just some code over the top of nms to make it easier to use

[visual tide]

unless youre dealing with setting millions of blocks the difference is negligible

[ancient plank]

?jd-s

[undone axle]

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

[quaint mantle]

Helo, I am making a signature plugin; Players can use a command so sign an item.
It adds a lore line to the item, and sets a value in the persistentState.
Now, when a player wants to remove that signature, cool, I can get rid of the entry in the persistentState, but, I cannot remove the line added to the lore, because I don't know which item in the lore list it is... ( also this can change in between )

This issue is for more stuff to do with custom items.

You don't have access to the individual ItemStacks, meaning everything has to be done from the outside.

[jade roost]

any recommendations for sites to learn java

[ancient plank]

?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.

[jade roost]

whats the best

in ur opinion

[topaz cape]

yk in new versions you can put water in the middle of some blocks which is annoying af for me because i now can't set the waterblock to air or it will remove the whole thing

is there any workaround to remove only the water?

[young knoll]

Yes

[ancient plank]

waterlogged

[young knoll]

BlockData -> waterloggable

(Waterlogged?)

One of those

[ancient plank]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/data/Waterlogged.html

[topaz cape]

can i just setWaterlogged false to when the block has only water?

🤨

[young knoll]

What

[ancient plank]

use your head

is water waterloggable

[young knoll]

Wouldn’t the question technically be is air waterloggable

[topaz cape]

yes

it's simply that

[ancient plank]

you're trying to make a question which is similar to "is water wet"

[topaz cape]

and i don't know if it's in Minecraft because dear god i can tell it's possible

[ancient plank]

https://tryitands.ee/

[topaz cape]

ugh smh

[ancient plank]

2$ water & air isn't waterloggable

[topaz cape]

I'll just check if blocktype is air or water

and will set it to air

[brave goblet]

what is nms again?-

[ancient plank]

net minecraft server

the minecraft server source code

[brave goblet]

ah ok

[brave goblet]

what is the advantages of that over spigot api?

[ancient plank]

there are some things which don't have an api in spigot but you should always use the api over nms

[brave goblet]

thanks makes sense

ty

[ancient plank]

since nms is per-version, it makes it harder to maintain your plugin across versions etc

[feral sand]

Hello. I'm trying to generate a block outline, however, right now, we are using an invisible shulker to get the outline. this works for most blocks, but for blocks like redstone, sugarcane, you see the shulker head. Is there another approach to get a block outline?

[ancient plank]

and nms isn't any faster than the api

[feral sand]

[sturdy frigate]

What is the max inv GUI size?

[agile anvil]

I guess 6 lines

[young knoll]

54

[wary harness]

would it be possible to do bigger with packets

[agile anvil]

No

[young knoll]

Maybe

[wary harness]

because exception for size is in bukkit

part

before 1.13

[young knoll]

But they are visually a mess anyway

[wary harness]

I think it was worjubg

[agile anvil]

Well if you succeed ping me please

[wary harness]

well if is possible

you can use custom

texture

[young knoll]

It overlaps the inventory iirc

[wary harness]

thru RP

[jade roost]

link

[sturdy frigate]

me too lol

I need an 8x8 inventory size

[wary harness]

time to do push up ladies

[agile anvil]

use a custom texture pack, and overlap it with the player's inventory

or try creating a slider

[sturdy frigate]

Wouldn't it be just a graphic rather than something you can store stuff in?

[agile anvil]

Well you'll need to do some code behind it to make it able to store things

[agile anvil]

muscle up*

[sturdy frigate]

What do I have to audit/change? Could you perhaps give me a rough guideline?

[wary harness]

I need a bar

[agile anvil]

Well this would be a mess for your player inventory cause it will remove two lines so you'll have to find an alternative for that

My best advice is to create a scroll inv

or make multiple pages

And then just listen to inventories events to do so

[sturdy frigate]

Gotchu, how do I make this?

[agile anvil]

well the easiest way is to create a paged gui
Create an inventory, put an item somewhere to change the page.
Listen to that item with InventoryClickEvent and whenever the player clicks, change the page.

For each page save the items as you wish, like a list or a map. And each time inventory is closed, save it

[sturdy frigate]

Ah I see, so it'll be like going through pages, thanks

[agile anvil]

right

good luck

[sturdy frigate]

my bad lol, i tried to react it

[tender shard]

GUIs are such a pain lol

[tender shard]

not only in MC but in general

[agile anvil]

Imagine how the world would be with bedrock's GUIs

[crimson scarab]

how can i check how close to the players center of screen a given entity is

[tender shard]

thb I never used bedrock so I have no idea

[agile anvil]

Well, are you good at geometry?

[daring lark]

guys, how could i set max durability of an item?

[crimson scarab]

not particularly but im down to learn

[tender shard]

damn that's going to be hard I guess

do you still have your math book from school? lol

[noble forge]

look at projective space

this is exactly how rendering works

[feral sand]

any thoughts?

[noble forge]

transforming a 3d point to 2d space

[tender shard]

well well well

it definitely is faster

the question is "how much faster" it is, and whether it's worth it to worry about it

e.g. setting blocks can be done waaaaay faster using NMS

[buoyant viper]

haha gluProject go brrrrr

[humble heath]

weard error any idea

[buoyant viper]

recursion issue

[floral drum]

uwu

[tender shard]

you keep calling your method from your method

[crimson scarab]

recursive

wrong reply

mb

[tender shard]

what's line 206?

[floral drum]

hi alex ❤️ ily

[tender shard]

happens to me all the time haha

I always reply to the wrong msg

[tender shard]

henlo ❤️

[humble heath]

how do i fix

[crimson scarab]

anywayi doubt i will be able to do the maths

[noble forge]

https://www.scratchapixel.com/lessons/3d-basic-rendering/computing-pixel-coordinates-of-3d-point/mathematics-computing-2d-coordinates-of-3d-points

[buoyant viper]

why do u keep calling getPlayer().getPlayer()

[noble forge]

this is a step by step guide

its for rendering but the math is the same

[humble heath]

that is how jobs do it

[noble forge]

treat the centre of your entity as 1 vertex

[noble forge]

i didnt know steve jobs knew java

[tender shard]

because getPlayer() probably returns a JobsPlayer, and another gerPlayer() will get the bukkit player

[buoyant viper]

damn

[floral drum]

oh my-

[buoyant viper]

also what is the code for EnderliteMasyer.luck()

[tender shard]

get out

[floral drum]

LOL

[tender shard]

https://tenor.com/view/get-the-fuck-out-gtfo-get-out-go-away-gif-8055436

[crimson scarab]

so i treat the player as a vertex

step 1

[humble heath]

any idea i am trying to get when you join a job it puts them in the rank of luckerms that maches the job

[floral drum]

weird thing to say - but I think I just cracked my hip and it felt so FUCKING weird 👀 wtf

[tender shard]

as said, what's line 206?

[buoyant viper]

and whats the code for EnderliteMaster.luck() method

[humble heath]

all in the picture i sent

[tender shard]

I can dislocate my hand

lemme send a video

[floral drum]

BET

[buoyant viper]

i think i can do it with my right shoulder

[quaint mantle]

I have a feeling I'm asking too hard questions xd

[buoyant viper]

the code for EnderliteMaster.luck is not shown there smh

also u dont have the actual line numbers shown

[noble forge]

actually theres another thing u could do which is way easier

[buoyant viper]

theres ur issue

[humble heath]

what the issue

[agile anvil]

Create a Vector between player and entity, create a vector in player direction, then find the vector to create an orthogonal triangle (pi/2 rad between the the one you create and the player-entity vector)

[buoyant viper]

ur calling luck inside luck

[floral drum]

I'd try and store the line in the PDC and then retrieve it when you're removing it to remove that line in the lore ❤️

[floral drum]

also, that's so fucking cool

never seen anyone do that before

[humble heath]

it works in other classes

[tender shard]

yes, very useful

lol

[floral drum]

Lmaoo

[agile anvil]

When you got this last Vector, compute it's projection to get the length on the screen (simple ratio)

[tender shard]

no

[humble heath]

it douse

[tender shard]

no

[buoyant viper]

not possible

[agile anvil]

Get the norm of the Vector, and compute the distance with the entity to find the length on screen

[tender shard]

public void luck() { luck(); }
this will ALWAYS cause a stackoverflow, I mean just look at it

[quaint mantle]

ohmm yeah that is a good option. not fullproof however which my perfectionist brain doesn't like xP

because line numbers can change

if you insert

[crimson scarab]

that seems so much lol i thought the api would have something

i just want to target entites that are closer to the crosshair

well i should learn some maths

[floral drum]

wrong ping

[agile anvil]

Ohhhhhhh you mean you want which entity the player is looking at ?

[floral drum]

Only if you insert above

[tender shard]

they wanna know which entity is closest to the crosshair, so raytrace wont help

[buoyant viper]

isnt there a method for that

[tender shard]

no

[noble forge]

another thing you could also do is compose a line shooting out of the players eyes. Then find the distance between that line and a point, being the entity’s pos. That would be high school math so probably the easiest

[agile anvil]

Lmao I went onto computing the "on-screen distance between crosshair and an entity"

[tender shard]

yeah ubt that's kinda what they need

[crimson scarab]

lemme draw diagram

[humble heath]

how do i fix then

[tender shard]

dont call luck() in your luck() method

[agile anvil]

Yeah for sure, but mine was to compute the onscreen distance lmao

[noble forge]

get vector between entity and player, use distance formula between line an point (look it up) ez pz

[noble forge]

at first mine was as well lmao

guess we both misunderstood

[tender shard]

how would that solve their problem?

[crimson scarab]

i have a homing weapon

[noble forge]

u want the closest entity to the crosshair right?

[agile anvil]

Fact is: which point ? 🙂

[proven falcon]

do you know how i can create a building who can produce like a barrel of the plugin brewelry but changin bloks or givin the item in the owen or in a chest
im on the voice chanel

[crimson scarab]

i want to target the creeper in the middle rather than the skeleton on the right

[noble forge]

entity pos

[crimson scarab]

programatically

[tender shard]

they want to get the entity the player is "trying to look at" even if they dont exactly look at it

[floral drum]

NICE PC

[crimson scarab]

THANKS

[floral drum]

❤️ ❤️

LMAO

[noble forge]

exactly what that method can do

get distance and sort to the nearest entity…

[humble heath]

when i remove return luck it gives red line

[tender shard]

then you get the closest entity to the target location, that's not what they wawnt

[glossy scroll]

dont u mean like

distance?

[noble forge]

distance to what target location?

[agile anvil]

Distance between a point and a Vector means nothing

[floral drum]

You need to return an instance of LuckPerms.

[noble forge]

why wouldnt it

[humble heath]

how

[crimson scarab]

distance from crosshair

[glossy scroll]

otherwise use world.rayTraceEntities in the direction of the player, and expand the entity hitbox by like 2 or so

[agile anvil]

@crimson scarab Do we agree on that statement: you want to get the entity the player is looking at, even if he's looking not directly at it ?

[floral drum]

What exactly would you want it to return? as the distance?

[glossy scroll]

then get the hit entity if one exists

[floral drum]

just the closest one?

[glossy scroll]

and use that entity

[glossy scroll]

@crimson scarab btw

[agile anvil]

Take a paper, draw a line, draw a point, and tell me what's the "distance between the line and the point"

[noble forge]

compose a line coming out of the crosshair, basically a vector. For every entity get the closest distance to that line. Sort to the nearest and voila

dude

the distance between a line and a point is defined as the closest distance

its basic high school maths

Let me find a link for it

[agile anvil]

Then we're talking, be precise, we're in a tuff world 🙂

[crimson scarab]

yes

[tender shard]

Imagine both the jägermeister and my phones (the white box) are entities. In this case im trying to point at the phones. If you just go by distance, it would return the jägermeister which is the wrong entity

[agile anvil]

No need x)

[noble forge]

https://en.wikipedia.org/wiki/Distance_from_a_point_to_a_line

[crimson scarab]

but not raytrace as i want to sort all the nearby entites

[floral drum]

TOE

[tender shard]

yes, I do have toes

[crimson scarab]

by how centered they are in the players vision

[tender shard]

would be weird if I hadn't any

[noble forge]

look at the link above. Your line is the player look at and the point is each entities position

[floral drum]

beautiful toes

[glossy scroll]

ok then

i have an idea

[humble heath]

how will i do that because anything i put in there dont work

[quaint mantle]

Basically, we want distance in 2d space so time to math

[glossy scroll]

take the displacement vector of the entity to the player

[agile anvil]

In any case I'll return the jager

[glossy scroll]

(entityLoc - playerLoc)

and then use the player's looking direction

and find the angle

smaller the angle, closer the entity to the crosshair

[noble forge]

to make it more performant just check for dot product

[agile anvil]

Best method, congrats

[crimson scarab]

so entity.getlocation - player.getlocation

what is the equation for angle

[floral drum]

damn never thought of that 👀

fucking nerd

[crimson scarab]

im not a math guy

[glossy scroll]

Vector.angle()

ive taken 4 years of calculus so im a bit familiar lol

[opal sluice]

Hi, can someone help me understand hows that even possible?

Error: https://pastebin.com/fXe31NZ2
Code: https://pastebin.com/vfHCh9dY

How it can make an access violation when I encapsulate all :/

[floral drum]

ah fair enough mart ❤️

[crimson scarab]

you are an inspiration to me lol

that is some commitment

[glossy scroll]

lol

ty

[floral drum]

martoph? more like marry me

[noble forge]

actually checking the dot product between the player look at and the vector between entity and player could be better for performance, since no trig. The dot product closest to 0 is the entity you want

just make sure both vectors are normalized

like rolyn mentioned earlier

I think

[glossy scroll]

You’re absolutely right

Well

[agile anvil]

Not sure about performance, but dot product is easier to accomplish

[glossy scroll]

Normalization is also pretty intensive

[noble forge]

fair enough

[glossy scroll]

sqrt

[noble forge]

its a cos vs sqrt

[floral drum]

just figure out a way to do it asynchronously!

LMFAO

[noble forge]

from my own testing a sqrt usually is less cycles than a cos

[crimson scarab]

"my own testing"

[tender shard]

sqrt is nothing to worry about unless you do it 10000 times per tick

[noble forge]

but who cares

this is minecraft

[agile anvil]

Complexity speaking it's slower x)

[noble forge]

its nothing high performance

[agile anvil]

Minecraft doesn't need to care about that kind of performance

[daring lark]

        setType(Material.IRON_SWORD);
        setAmount(1);
        ItemMeta meta = getItemMeta();
        meta.setDisplayName(ChatColor.WHITE + "Miecz z Wytrzymałej kości");
        meta.setCustomModelData(1000000000);
        AttributeModifier modifier = new AttributeModifier(UUID.randomUUID(), "generic.durability", 0.101, AttributeModifier.Operation.ADD_NUMBER);
        meta.addAttributeModifier(Attribute.GENERIC_MOVEMENT_SPEED, modifier);
        meta.getItemFlags().add(ItemFlag.HIDE_ATTRIBUTES);
        setItemMeta(meta);
    }``` why is this code not hiding attributes?

[noble forge]

just use whatever is easiest honestly

[glossy scroll]

Dot is tricky cuz itta hard to visualize what it means

[noble forge]

the dot product tells you how similar two vectors are

[glossy scroll]

angle uses acos i think

[noble forge]

thats just it

[glossy scroll]

Wait

I think to use angle

[noble forge]

atan2 actually

[humble heath]

can any one plz help me

[glossy scroll]

You also need to normalize anyways… it takes the magnitude of the two vectors

[noble forge]

no you dont

lookat is already normalized

[glossy scroll]

Well i mean

[noble forge]

and converting vector to angle doesnt require normalization

[agile anvil]

In all case angles and dot are linked

[glossy scroll]

The angle function

Honestly just use dot

Im almost certain its “faster”

[agile anvil]

In term of simplicity use dot

[noble forge]

at this point were nitpicking lol

weve handed them 2 different ways of solving it

they can decide what to use as either of them have pros and cons

[agile anvil]

Hope we haven't got him lost

[noble forge]

a little high school vector math doesnt hurt

[glossy scroll]

if theyre still paying attention that is lol

angle is definitely more intuitive

[noble forge]

i agree

[crimson scarab]

entity.getLocation().subtract(player.getLocation()).toVector().angle(player.getLocation().getDirection())
does this look ok mathmatically wise

[weary cobalt]

What would the prepared statement be for creating, and adding to an array in SQL? I've found ARRAY_APPEND, but not sure how to use it in this context.

Example of how I'm setting integers: setInt(String uuid, String category)

PreparedStatement ps = connection.prepareStatement("UPDATE " + table + " SET " + category.toUpperCase() + "=? WHERE UUID=?");
ps.setInt(1, value);
ps.setString(2, uuid.toString());
ps.executeUpdate();

Any sort of help would be appreciated

[agile anvil]

Depends on the level, 3D angles need to introduce a plan so can be harder sometimes for some...

[glossy scroll]

yes but please designate some of these to variables

[dense geyser]

I'm using a DAT file to save data, how can I clear the data in the file to save it again without erasing the file? Or is there a way of editing lines of those files with data already in it without just making more lines?

[glossy scroll]

DAT... as in nbt?

[crimson scarab]

i would but its gotta be used inside an optional predicate

[glossy scroll]

i mean

you could expand it

o -> {
    return true;
}```

or make it a function

[buoyant viper]

not scientifically posible

[glossy scroll]

private boolean myPredicate(ObjectInPredicate) {
    return true;
}```

and then this::myPredicate

[crimson scarab]

is it possible to use multiple min statements in an optional

[agile anvil]

Show your code

[river oracle]

don't reccomend using optional's in java

just use null checks the only reason you should ever really deal with them is in java streams

[agile anvil]

it makes the code sexier

[river oracle]

it also makes it 3x slower (at low frequency)

[crimson scarab]

Optional<Entity> optionalEntity = nearbyEntities.stream()
                .filter(entity -> entity instanceof LivingEntity && ((Projectile) arrow).getShooter() != entity)
                .filter(entity -> ((LivingEntity) entity).hasLineOfSight(arrow))
                .min(Comparator.comparing(entity -> entity.getLocation().distanceSquared(arrow.getLocation()) * entity.getLocation().subtract(player.getLocation()).toVector().angle(player.getLocation().getDirection())));

graphs

[river oracle]

holy my eyes

?paste

[undone axle]

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

[river oracle]

discord formatting really fuckeed that

[agile anvil]

I'm interested in reading some explaination about it, is it a personal test or something known?

[river oracle]

well if you think about it an Optional is just another object in java's back end

so all your doing is creating another object to do the null check for you

[agile anvil]

Yeah I understand, more memory, more time to allocate memory, and (little) time to do checks

[river oracle]

if you use Optional's all the time its going to be creating lots of Optional objects for every var to manage nulls that stacks up

[candid shoal]

How to I delay a function in ticks

[river oracle]

Bukkit#getScheduler#runTaskLater

[candid shoal]

I’m still new to this what does this mean

[crimson scarab]

Bukkit.getScheduler.runTaskLater(plugin, task -> {
     do stuff
}, 20L, 1L);

Thats how its done i think

[river oracle]

learn java :/ but the # are just dots

Bukkit.getScheduler().runTaskLater(Plugin, task)

[crimson scarab]

sorry for spoonfeed but i found scheduling difficult when i started it out

it just takes time to understand i think

[candid shoal]

Thanks

[crimson scarab]

private Location playerLocation;
is this bad naming

[agile anvil]

No

Why would it be ?

[crimson scarab]

i assume i am wrong

most of the time

personal opinion:
should targeting for homing projectiles be:
100% closeness to crosshair
100% distance to potential target
50% distance 50% crosshair
other ->

[humble heath]

how do i uncapitalise messages

[eternal oxide]

.toLowercase()

[crimson scarab]

learn java message incoming

[agile anvil]

I don't understand

[crimson scarab]

so i have a homing weapon how should the automatic targeting for entites be based off

like should the closest enemy be targeted

or should the enemy most visible by the player be targeted

[agile anvil]

I'd say the player should select the entity at launch, and then it will keep the same entity

[vocal cloud]

Well, if you want frustrating make it closest. If you want a more enjoyable mechanic it should be targeted

[agile anvil]

I imagine a kind of cool glow effect to select the entity to reach

[crimson scarab]

thats a really good idea actually

[agile anvil]

Free ideas tonight

[crisp forum]

Can I make a unenchantable item enchantable on enchanting table

[rough drift]

Maybe highlight in hex the closest enemies that the player can see

[vast raven]

How to add a default configuration section?

[rough drift]

so not likely to be targeted in red

basically the target in 0xff0000

using colored glow

anyways gtg

[crimson scarab]

cya

[agile anvil]

https://letmegooglethat.com/?q=spigot+add+default+configuration+section

[vast raven]

I've already searched up

Really funny

[agile anvil]

I love this website

[vocal cloud]

If you've searched it how did you not find it

[vast raven]

I am not stupid, not at all, searching on Google it's the first thing I do.

[vast raven]

Great question.

A sec

None of these answers can help me, except the last one, that suggested instead to create the section if it doesn't exist.

[agile anvil]

So now, step 2 if you didn't find your answer, explicit it more clearly, more precisely

[vast raven]

You should skip on 3rd step since I've already done that, but I'll do it again so: "How do I create a default section in a config?".

[agile anvil]

That's exactly the search you've done, so you're still on step 1

Open your mind, try to think more deeply

[eternal oxide]

What do you mean by "default section"? Do you mean set default values? or simply create a section via code?

[vast raven]

searching_stuff != ask_to_some_one;

[agile anvil]

Look ElgarL questions, that's the one you need to explore

[vast raven]

The exact same thing you do when adding a default Value to a config, but with a section, so basically create a section if doesn't exist.

[torn shuttle]

you're right, 5G DOES mean the earth is flat

how else would the waves travel?

[agile anvil]

You just opened my mind

[torn shuttle]

thanks rolyn

[eternal oxide]

all you do is set with whatever data you want to put in

[sturdy frigate]

how do i rename item stacks?

[onyx fjord]

earth IS flat

[torn shuttle]

this is fantastic, we really managed to empty our minds thanks to Rolyn

[vast raven]

Does it override if it already exists?

[eternal oxide]

yes

[torn shuttle]

next I think everyone should move their projects to Kotlin

[vast raven]

So it's not what I've asked for..

[agile anvil]

So...

[eternal oxide]

Then test if it exists before adding it

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/configuration/ConfigurationSection.html#isConfigurationSection(java.lang.String)

[vast raven]

So it's the same thing on that page, but I think there is a way of doing it without checking the existence of the section.

Like using one of this method.

[torn shuttle]

oh yeah has anyone played around with setComments already? I noticed that was added semi-recently

[onyx fjord]

yesterday i made so complex if statement that my muscles legit started to hurt

[torn shuttle]

methinks you need to hit the gym or at least get up more than once every year

[eternal oxide]

No, that will still overwrite an existing section

[onyx fjord]

No.

[young knoll]

The defaults system for configs is weird

[vast raven]

Uh, fine, I thought that the "default" word would work as the addDefaul() logic.

[young knoll]

I’ve never actually used it

[torn shuttle]

then you'll have to suffer me flexing on you for the rest of your life. I'm doing it right now, I just came home from the gym

[onyx fjord]

real men use boostedyaml

[torn shuttle]

no one used setComments?

[onyx fjord]

too big? just use plugin.yml libraries

[torn shuttle]

guess I'll try it out myself

[vast raven]

Should I add a config in the resources?

[young knoll]

Yes

[eternal oxide]

Default in the context of a Configuration is simply referring to a value that is provided if no actual value has been set.

[vast raven]

Thanks, that helped, it did the opposite someone else. (coff coff)

[eternal oxide]

ie, you can define a whole yml as the Default and its values will be returned unless you set your own

[crisp forum]

Should I open a thread about my question?

[eternal oxide]

I didn;t see any question, sorry

[agile anvil]

What is it ?

[crisp forum]

.

[eternal oxide]

an example item?

as you can apply any enchantment to any ItemStack

[quiet ice]

On spigot? Not reliably

[eternal oxide]

you can addUnsafeEnchantment

[crisp forum]

I don't want to enchant it, I want players to be able to enchant it on enchanting table

Like a steak that is enchanted by a player will give more saturation

[young knoll]

Yes

PrepareItemEnchantEvent and manually create offers

[crisp forum]

Oh, I'll listen the event and change it's content?

[bronze night]

I have been playing with some code and wanted to use one entry from stringList #1 and add the entry from the stringList #2 to it and i used 2 for loops and got the output i wanted, but there's an issue that it pastes 4 messages instead of 2. Could someone give me a tip how can i fix it? (codes is below)

[crisp forum]

I'd probably make plugin a static variable first of all

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[crisp forum]

If I have lots of event & command handler classes I do the plugin static, it works Fine

[grim ice]

bro

do u mean public static?

i didnt assk u

i asked him

lol

mb

but well

i asked him

and btw

di isnt better than that

theyre seriously the same. except that a singleton pattern is better in this case

[coral oyster]

Hi when I set a displayName for an itemStack, the intellij linter says method invocation for"setDisplayName" may produce "nullPointerException"
its not really affecting my plugin as it is working as it should, but out of curiostiy, what could this mean?

[grim ice]

since a plugin main class is a singleton in the first place

[grim ice]

if the bookmeta is null

itll return an error

e.g

ItemMeta meta = null;
meta.setDisplayName("hello");

this will throw an npe

[coral oyster]

ah ok, thanks!

[buoyant viper]

it means bookMeta could be null

[tame bay]

Hey there.
Im trying to add a command that gets the displayname and lore of an item and saves it to a config

However since the displaynames are colored using & they get replaced in my yaml file.
In order to make yaml not replace those reserved symbols I would need to escape them using ' at the beginning and end of the string

How can I add those ' plugin sided?

I already tried adding "'" before and after it but that only resolved in this ''' in my yaml file

[iron glade]

Can I simplify this even more?

String singularPlural = newDelay == 1 ? newDelay + " second" : newDelay + " seconds";
String finalOutputMessage = newDelay == 0 ? "none" : singularPlural;```

[grim ice]

String outputMessage = newDelay == 0 ? "none" : (newDelay == 1 ? newDelay + " second" : newDelay + " seconds);

[quiet ice]

Pft, how inefficent

[grim ice]

just do

newDelay + "s"

tbh

[iron glade]

That would be an easy solution I guess, but I want "seconds" to be spelled out

[grim ice]

then do what i sent

thats the shortest way u can do it

[iron glade]

Yeah, looks a bit ugly but ur right, thanks!

[tame bay]

2Hex? Do you by any chance have a solution to my question aswell? 😄

[grim ice]

well

the string ur trying to save

has "&" in it, right?

[tame bay]

Yup

It grabs the displayname of the item. So it has &6Displayname in it

for example

[iron glade]

What's the problem with the config?

& symbols saving fine for me in yaml files

[grim ice]

same

is it that german SS symbol?

ß

this?

[tame bay]

no 😄

[iron glade]

§?

[tame bay]

wait

let me check

[grim ice]

§

[valid folio]

Umh??

[grim ice]

this?

or is it "\xa7"

[eternal night]

looks like you fucked with the jar while the server was running

[iron glade]

Use ChatColor#translateAlternateColorCodes in that case before saving to config I guess

[grim ice]

if its so then do replaceAll("§", "&"); to the string before saving

[grim ice]

nope

[iron glade]

ahw ait ur right

[grim ice]

u should do the opposite of that

ye

[iron glade]

yeah I confused them for a sec lel

[grim ice]

lol

[desert frigate]

How do I make two chests connect to a double chest?

Cause I tried and they don't connect

[iron glade]

Usually I just take them and place them next to each other funny

[tame bay]

yup

my bad

displayname returns with §

instead of &

thanks 😄

[grim ice]

did u do what i told u to

[iron glade]

What exactly are you doing? Setting 2 blocks to chest next to each other?

[grim ice]

replaceAll("§", "&");

to the string

before saving

[tame bay]

thx for the hint ❤️

[bronze night]

anyone got a clue why the output is being doubled when i use for loop inside of a for loop?

[grim ice]

https://www.spigotmc.org/threads/help-spawning-a-double-chest.351667/#post-3260174

ok yall gn

[bronze night]

or rather why is it output in 1, 1, 2, 2, 3, 3? instead of 1, 2 ,3

[desert frigate]

yes

[dense geyser]

yes, sorry

[eternal oxide]

https://www.spigotmc.org/threads/help-spawning-a-double-chest.351667/

wrong ping

[desert frigate]

doesnt work

[iron glade]

displayName.length() == ChatColor.stripColor(displayName).length()```
Does this make sense to check if a string contains a chatcolor?

[worldly ingot]

It won't be equal

[iron glade]

Or is there some method I'm missing

[worldly ingot]

Oh you're checking if it has any colour

Yeah in theory that would work

[young knoll]

Can’t you just use .equals

[worldly ingot]

I'd personally opt for an equals() check too

[iron glade]

alright then I'll try that

[desert frigate]

no idea

[rough blaze]

how would I play a sound a player's location?

does thread.sleep work as a timer

why

[young knoll]

Because it halts the thread

And most of the server runs on that thread

[night torrent]

ohh

so i have the use schedules?

Im trying to make a slight delay between click and check

because when you equip the helmet in game its not registering

you have to click somewhere in your inv

alr, ill check it out!

[crude charm]

Why not just use #runTaskLater

...

[night torrent]

thats fine

thanks

is it possible to add items to the creative inventory?

[young knoll]

No

[night torrent]

ok

and could i get a little help intergrating runTaskLater into this code?

I want a delay before the check is done so it waits a little and then sees if he has a helmet

[crude charm]

first off, fix your brackets, thats ugly af

Why so many plugins

also #help-server

[halcyon pumice]

got it thank you wasnt sure :D

[night torrent]

nah
{
}
is better

[crude charm]

This is java not c#

It's not

[night torrent]

difference?

[crude charm]

In java you don't place the bracket on a new line

In c# you do

[night torrent]

so prefrence

[crude charm]

No

[night torrent]

???

[crude charm]

Practice

[quaint mantle]

it's all just personal preference

[night torrent]

mhm

[crude charm]

wait...

[young knoll]

As long as you keep it the same throughout the project

Then meh

[desert frigate]

how can i get the killer in PlayerDeathEvent

[crude charm]

Ah yes

[night torrent]

yeah i usually do capital method names i just didn't for that one

[crude charm]

Thats objectively wrong

[night torrent]

?

[desert frigate]

alrught

[crude charm]

Yup

[young knoll]

Java names are meant to be lowerCamelCase

[night torrent]

Player killer = event.getPlayer().getKiller();

[crude charm]

variables are atleast

and packages are all lowercase

classes are CamelCase

[young knoll]

Variables and method names

[crude charm]

^

[young knoll]

Except for static final variables

[crude charm]

yup

then it's STATIC

all capital

[rough blaze]

How would I play notes at a player?

[crude charm]

Depends what u mean exactly

[night torrent]

???

[crude charm]

like a piece of music?

[crude charm]

"this" is supposed to be an instance of main

[night torrent]

ok but runTaskLater isn't recognized

[crude charm]

what does it say

^ unless thats what you defined "scheduler" as

then it should work

as well

[rough blaze]

yes, I plan to use the wait feature to make a string of notes

[crude charm]

NoteblockAPI

[young knoll]

Don’t sleep the main thread

[crude charm]

^

[night torrent]

        scheduler.runTaskLater(Main.getPlugin(), () -> {

        }, 20L, 20);```

this is the code you gave me

[crude charm]

Why define a variable, takes up a line for no reason, not like you're gonna reuse it and if u do then u can make one

[night torrent]

I tried that to fix runTaskLater

yeah, got that now

Thanks!

[eternal oxide]

runTaskTimer

[crude charm]

Also PLEASE look at your naming conventions, not only makes you code look amateur but is objectively wrong, see;

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

No idea, they keep taking mine for some reason.

i dont think maven affects .java files on compile

[coral oyster]

ah ok yes that was my intent. I wanted to have a loading message outputted to the console displaying the version of the plugin.

you can use maven to set the plugin version in plugin.yml

just sync that and read it

how could I sync that?

sorry but I just don't get what is wrong here

            }
        }
    }

Even in a server with only one player, it sends the welcome message for that player twice, as in
name JOINED!
name JOINED!

[tulip nimbus]

Why do it that way? You can do Bukkit.broadcastMessage("");

Unless you're purposely only broadcasting to the players in that world

[boreal sparrow]

Yea

I am

But I don't get why it executes twice

[tulip nimbus]

You can avoid the loop entirely if you're not on older version of Java, maybe world.getPlayers().forEach(player -> player.sendMessage(""));

[boreal sparrow]

ok, ill try that, thanks!

[drowsy helm]

just use Bukkit.broadcastMessage

[tulip nimbus]

He only wants to broadcast to players in the specific world

[drowsy helm]

ah didnt see that

[boreal sparrow]

I will try this, but can someone explain why my code above didn't work? It seems logical to me

[boreal sparrow]

still displays two times

[frosty tinsel]

Maybe the event gets fired twice

[boreal sparrow]

I though so too, but how? ChangeWorld event only fires once when a player changes worlds?

Hi i made this code with protocollib one thing how i can get the message sent by the server?

[sturdy frigate]

How do i change spawn point orientation?

[ornate zinc]

hello . i want to make a plugin when i kill a zombie summon a nother zombie and when i kill secend one , do an action

public class spawn implements Listener {

    @EventHandler
    public void onDeath(EntityDeathEvent event) {
        if (event.getEntity() instanceof Zombie) {
            if (event.getEntity().getKiller() != null) {

                World myWorld = Bukkit.getWorld("world");
                Entity entity = event.getEntity();
                Location spawnLocation =entity.getLocation();
                Entity spawnnedZombie = myWorld.spawnEntity(spawnLocation, EntityType.ZOMBIE);
            }
        }
    }

[crude charm]

Rename ur class

[brave goblet]

maybe custom name your second zombie so u can test for it

[crude charm]

bump

[ornate zinc]

tnx

How can I get the numbers of players in a given world?
I use this but it's giving me problems

public static int getPlayerCount(String world) {
        World converted = Bukkit.getServer().getWorld(world);

        assert converted != null;

        int count = 0;

        for(Player p : Bukkit.getOnlinePlayers()){
            if(p.getWorld() == converted){
                count++;
            }
        }
        return count;
    }

wait im dumb

(Bukkit.getServer().getWorld(world)).getPlayers().size();

[brave goblet]

No idea sorry

[boreal sparrow]

... this doesn't really work

is there a better way to get the amount of players in a world?

[crude charm]

Does it work or not?

It shoulkd

[boreal sparrow]

no

[crude charm]

Why not?

[boreal sparrow]

the first player that joins it says 0

the second player 1

[crude charm]

so add 1

[boreal sparrow]

and the third player zero again

[crude charm]

Bukkit.getServer().getWorld(world)).getPlayers().size() + 1; 

[boreal sparrow]

.

[crude charm]

Huh

[boreal sparrow]

i know it makes no sence

this is the method:

public static int getPlayerCount(String world) {
        World converted = Bukkit.getServer().getWorld(world);
        return Objects.requireNonNull(Bukkit.getServer().getWorld(world)).getPlayers().size();
    }

Called like this:

//Player World Change Event
Player player = event.getPlayer();
World world = player.getWorld();

//Send join message to everyone
for (Player p : world.getPlayers()) {
  p.sendMessage(player.getName + Handlers(Dumb class name i know).getPlayerCount() + " has joined the world!"
}

[manic ice]

getPlayerCount needs a world argument, doesn’t it?

[boreal sparrow]

i passed in the wrong arguments

XD

[manic ice]

anyways instead of using the world name use the actual world object

also you should probably use Bukkit#broadcastMessage instead of sending all the players a message manually

[keen obsidian]

Hey folks, I'm having some difficulty with raytracing.

The goal is to raytrace from a block to a nearby player and see if the raytrace hits the player rather than a block in the way.

I've been testing the following code to do this, however, the RayTraceResult is always null for some reason:

Any advice on where I'm going wrong would be much appreciated! ❤️

help !

[ashen quest]

from the code xd

is there a method in the api?

[ashen quest]

?notworking

[undone axle]

"Does not working" is a useless statement. Please describe what exactly is not working, what you expect it to do, and what actually happens. If you get any console errors, also ?paste the entire stacktrace.

[knotty cloak]

Bukkit.getWorld("world ").isHardcore();
(example)

[ashen quest]

ou

ty fam

xdd

[glass mauve]

is there a properly way to indicate optional arguments for a command in plugin.yml

[ivory sleet]

not really

Ig u could do it with command usage

[glass mauve]

yea but how do I show that it's optional?
like /<command> argument doesn't show it as optional

[azure hawk]

how can i get the Integer out of the Hasmap (ik ?learnjava im on it xd)

[ivory sleet]

myes but you can use sth like

[glass mauve]

look into docs HashMap got a get method

[ivory sleet]

usage: /<command> [optional] <required>

[glass mauve]

ok ty

[ivory sleet]

tho I personally use brig directly as that has good support for arguments and literals

[glass mauve]

but it makes sense to put all optional at the end right?

[ivory sleet]

hmm I believe so

or use command flags

if you have a lot of optional stuff

like

[ivory sleet]

-something=value

[glass mauve]

get(player);

so you get the iNteger mapped to the player

[azure hawk]

ohhh ok bruh

[glass mauve]

also learn Java before api's

[ashen quest]

pickup item is a string

not an int

[glass mauve]

the error literally says why it's wrong

[glass mauve]

you prob want pItemCount++

[azure hawk]

BRUH

[glass mauve]

but not enough information

[azure hawk]

I TABBED THE WRONG

HAHHA

shit

lol

sry

and now i wanna put the value back into the hashmap

but how

[tardy delta]

If the player is not present in the map you Will get a nullpointer

[chrome beacon]

You put the value in there once

It's the same the second time

[sturdy frigate]

how can i stop magma block damage? & deny ice slipperiness?

[azure hawk]

ok

[chrome beacon]

Also please learn Java instead of wasting our time here with Basic Java questions

[agile anvil]

Check the entity damage event, and cancel the event. For the ice it's impossible

[chrome beacon]

^^

[sturdy frigate]

Aw man, can i register a new block and steal ice textures? without making a resource pack

[agile anvil]

No :/

[chrome beacon]

You need mods to register new blocks

[agile anvil]

You'll need a resource pack

[sturdy frigate]

Oh really

Okie thanks

[agile anvil]

But resource packs are great, use it!

[sturdy frigate]

Sure!

Wait, since you said i need mods, can i not do it serverside?

Or is my only option to set a random/unused block textures to look like ice

[agile anvil]

What's your version ?

[sturdy frigate]

1.19

[chrome beacon]

This

You cannot add new blocks

[agile anvil]

Then with custom model data you can use a block and change it's texture without affecting others

[chrome beacon]

Blocks cannot have custom model data

[agile anvil]

Oh my bad

[sturdy frigate]

Geez okay

[agile anvil]

I'm not sure but you should check datapacks. I think they allow you with resource packs to add blocks

[chrome beacon]

They don't

[agile anvil]

Ok I stop talking

lmaoo

[sturdy frigate]

:(( it's okay, thank you guys

[noble lantern]

noteblocks are one of the best options for this

easiest too

mushroom blocks are next easiest, but theyre more annoying since breaking adjacent ones change block states (Which is whats used to change the texture)

[marble copper]

Guys anyone know how to make a rotatinf shop with stock using deluxe menu?

[sturdy frigate]

Oh, why are they easier than other blocks?

[noble lantern]

its subjective, but overall its a lot less overhead to work with

[agile anvil]

Go to #help-server for plugin help

[sturdy frigate]

Ah I see

thanks 👍

[crude charm]

BOOP

[chrome beacon]

Did you modify the config file?

And not reload it

[keen obsidian]

Bump

[chrome beacon]

It's null when it doesn't hit anything I believe

[tender shard]

what's the repo for authlib, brigadier etc again?

I thought it was libraries.minecraft.net ubt that's a 403
