[mellow comet]

and how?

[ivory sleet]

explain what you mean

Team::getEntries

it will return a set of strings

[mellow edge]

will this get online or offline players?

[ivory sleet]

it will get all registered strings to the team

for instance a team can contain the "player name" $ or sth

[mellow comet]

I would like to be able to change the default / fallback of the bungee cord with a bungee cord plug-in during operation.

[ivory sleet]

yeah that should be possible

[mellow comet]

Do you know how?

[ivory sleet]

not exactly but it depends on what you're doing in the operation you mentioned

[mellow edge]

                        a.forEach((offlinePlayer -> {
                            Player plr = offlinePlayer.getPlayer();
                            if(offlinePlayer.isOnline()) {
                                plr.sendTitle(ChatColor.DARK_RED + "BED DESTORYED", "", 123, 6000, 123);
                            }
                        }));```

i did that

[tardy delta]

what's the point of the user factory when it's every time User::new?

also i dont understand why using an Optional 😄

[young knoll]

Optional is nice

Because you can chain ifPresent

[spiral light]

has anyone an idea on how to prevent stackoverflowerror while replacing all lava in a chunk with air ?

[mellow comet]

I only want to set a server that has already been registered, for example with the name as the default server.

[tardy delta]

yea but in this case idk

[young knoll]

Split up the task

[spiral light]

thought about that but that sucks ^^

[ivory sleet]

avoiding nullable return types

it makes it more explicit that the return type might intentionally be null

thats to decouple User creation from instantiation (the factory)

but probably unnecessary

[solid cargo]

is there any plugin that rigs your tps? i need to test my plugin on low tps

[ivory sleet]

I mean the rigging the visual tps wont do anything

however if you wanna rig the tps, could just use Thread::sleep

[solid cargo]

i want the server to act like 15 tps

any simple plugin to do that?

[hybrid spoke]

#help-server

[solid cargo]

ehh ok

[ivory sleet]

hmm unsure actually and yeah probably a question for the hs channel

[buoyant viper]

is there a way to make sure ur plugin gets unloaded last

[solid cargo]

lets move over there

[tardy delta]

conclure, what do you mean with humblestorage (that makes the most sense of those two) and delegatingstorage?
the first one is the super type where the second one is designed for more specific uses?

[chrome beacon]

Don't think so. Why do you need this?

[tardy delta]

also i havent thanked you 💗

[ivory sleet]

no, the humble one takes away/decouples anything with concurrency and multi-threading

[tardy delta]

ah in that way

[ivory sleet]

then we have a wrapper which just incorporates and wraps it around a future

[olive lance]

i feel like if it was a depend in spigot then it would handle accordingly in unloading but nothing says that specifically

[ivory sleet]

its quite a good practice to avoid poor concurrency and multithreaded designs

of course you shouldnt follow it blindly like any good practice but yeah

[urban bramble]

I have a custom block populator that's not using the world generation API (for various reasons), and it seems like Block#setBlockData(data, false); is still causing nearby chunks to be generated, even though I'm specifically against that. Any clue why it might be, and how I might mitigate it? https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/block/Block.html#setBlockData(org.bukkit.block.data.BlockData,boolean)

[spiral light]

what version ? currently have had the same issue with updaing neightbor chunks ... i now just use getBlock().setType(material, update=false)
in 1.18.1

[tender shard]

Statistic.html#TIME_SINCE_REST

returns the time in ticks, right?

I know I could just check it but I thought maybe someone knows

[urban bramble]

but setType doesn't set the BlockData unfortunately

[spiral light]

could be probably seconds too ... but i think its ticks

[tender shard]

hm

Ill have to check it then 😄

[spiral light]

good way to check is ingame-cmd /data entity get .... ^^

[spiral light]

what blockdata do you set ?

[lone jacinth]

Do your self a favour and use the new BlockPopulator api if you are on 1.17 or 1.18

[tender shard]

how does that work for stats?

[spiral light]

there should be an value in the player data for that too ^^

[urban bramble]

blockData copied from another block elsewhere

[urban bramble]

unfortunately I cannot

I really want to, but constraints and how stupid the idea I'm working on make that impossible

[spiral light]

the problem with blockpopulator is the limited region where you can set blocks :/

[lone jacinth]

You have a 3x3 chunk area to work this should be enough for normal chunk populations.

[spiral light]

there is always something called nms ^^ bad idea to use but if you dont care about light updates you can use nms ...

[urban bramble]

I want it to support multiple versions

and I'm way to lazy to use reflection

[tender shard]

it's indeed ticks

[spiral light]

that way i would need to check if my structure will generate something out of the 3x3 area and move it back into the region ^^

[urban bramble]

anyway, it seems like the API should do what it promises to do

instead of straight up lying

[vale ember]

will there be an exception if i try to unregister listener via HandlerList.unregisterAll(Listener), if listener isn't registered?

[urban bramble]

maybe I'll make a spigot PR

[buoyant viper]

i dont see why it would tbh

[spiral light]

also sadly generating worlds in nms is a lot faster then using api ^^

[lone jacinth]

If you have structures which are bigger than 3x3 chunks than you should split them up. (Which also minecraft vanilla those with bigger structures)

[spiral light]

i wish i had an idea to get where structures ended and need more generation if the chunks load ^^

[sacred mountain]

can anyone help create some code for me? I need a small snippet of pseudocode made in java.

[spiral light]

ok:
if question.isbad || question.hasnoinformation
// dont answer
else
// try to help

[sacred mountain]

?

[spiral light]

you want pseudocode but dont describe about what

noone will know if he can do this for you since the task is unclear

[sacred mountain]

when a player places bucket of liquid:
add location to list
if it gets removed by the plugin regen, remove it from the list
if it gets picked up again, remove it from the list
if it gets blocked by a block then remove it from the list
on pickup water, check if water location is in list of player placd water, if it is then return? and if it sint then cancel and send a message "You can only pickup liquids placed by a player•

[spiral light]

you bassically look for
PlayerBucketFillEvent and PlayerBucketEmptyEvent
and also BlockPlaceEvent

[tender shard]

Warning: question.hasnoinformation will always be true

[sacred mountain]

im bad at java lists

since im used to python more

how would i add and remove coords from a list

or a storage method

[visual tide]

theList.add(location)

[sacred mountain]

and to check it to a playerbucketfill event would be something along the lines of

if pla yer bucketfill location is in mylist

[visual tide]

well check if the list contains the location

[sacred mountain]

or would i have to loop it to check

[tender shard]

though be aware that locations are exact

[sacred mountain]

in visual basic i do smn like

for c in mylist:
if location = c

[visual tide]

block location then

[sacred mountain]

how would i check coordinates not exact

[tender shard]

for(Location loc : myList) {
  if(loc.equals(someOtherLocation)) { ... }
}

[tender shard]

I have my own class for that, called SimpleLocation

[bitter fulcrum]

Are there any ways to perform bytecode modification

[visual tide]

asm

[sacred mountain]

oh right

can you share it?

or how to store coords instead of exact locations

[bitter fulcrum]

How would I go about using it in a plugin

[visual tide]

as dependency

[bitter fulcrum]

Alright

[tender shard]

package de.jeff_media.test;

import org.bukkit.Location;
import org.bukkit.World;

import java.util.Objects;

public class SimpleLocation {
    
    private final int x, y, z;
    private final World world;

    @Override
    public String toString() {
        return "SimpleLocation{" +
                "x=" + x +
                ", y=" + y +
                ", z=" + z +
                ", world=" + world +
                '}';
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        SimpleLocation that = (SimpleLocation) o;
        return x == that.x && y == that.y && z == that.z && world.equals(that.world);
    }

    @Override
    public int hashCode() {
        return Objects.hash(x, y, z, world);
    }

    public int getX() {
        return x;
    }

    public int getY() {
        return y;
    }

    public int getZ() {
        return z;
    }

    public World getWorld() {
        return world;
    }

    public SimpleLocation(Location location) {
        this.x = location.getBlockX();
        this.y = location.getBlockY();
        this.z = location.getBlockZ();
        this.world = location.getWorld();
    }
}

[bitter fulcrum]

Do I need to include it in the jar?

[visual tide]

yes

[sacred mountain]

thanks :)

[tender shard]

Just wrote it new, I didnt find the original one lol

[sacred mountain]

ur quick

[tender shard]

you can now just do SimpleLocation simpleLoc = new SimpleLocation(location)

then compare them using equals()

[sacred mountain]

so how would i yse that

to chdck where a player placed

water

do i use the playerbucketfill thing to

[glossy marsh]

Hello! I've got a question. I have a plugin in which you can craft custom clocks which have an enchantment attached to them, these clocks have a different colored name when you craft them (the name is green). If you go to an anvil and rename the clock the color of the name will turn to blue instead of green. Is there an easy way to keep the color of the name of the renamed item green (also in the suggested name part of the anvil?)

[sacred mountain]

i think thats texturepacks

maybe im wrong but i dont think plugins can change colors of items

[visual tide]

after it's renamed, get the name, strip the color and then recolor it

[glossy marsh]

I'm talking about the color of the name

[sacred mountain]

ohh

translatealternatecolorcodes?

[visual tide]

use PrepareAnvilEvent then do what i said earlier

[visual tide]

.

[sacred mountain]

okay nvm lmao

[glossy marsh]

I was thinking about this as well by making a listener, do you know if this also makes it possible to keep the name in the name suggestion part of the anvil the same color?

[visual tide]

not sure what you mean with name suggestion part

[lethal knoll]

If I would iterate over all worlds using bukkit.getWorlds() , is that going to be acceptable in terms of performance?
more specific this:

        for(World world: Bukkit.getWorlds().stream().filter(this.sleepService::isEnabledAt).collect(Collectors.toList()))

If I do that every second

[glossy marsh]

I'll try this, I was just hoping there was an easier way, like when you rename an enchanted golden apple the color in the anvil part remains purple

[lethal knoll]

if I do that every second*

[visual tide]

because that's a part of minecraft and not a custom name

[glossy marsh]

I'll try my best to recreate it for you

[misty current]

unless you have thousands of world (which should be questionable on its own) or execute any complex/network stuff per world it's fine

[lethal knoll]

Every second right? so a repeating task like this every second

[misty current]

yes

we live in 2021

[lethal knoll]

Alright, thanks for the info

Yea, but sitll

[misty current]

computers are not doo doo

[lethal knoll]

I tried to think of different solutions

But there is no for now

[visual tide]

😬 depends

on the context

[fathom cobalt]

Wrong, they really are doo doo sometimes

[misty current]

most people tend to underestimate modern computing power

[lethal knoll]

yea well

[visual tide]

define modern

[glossy marsh]

Is it possible to upload a video in this channel?

[fathom cobalt]

Don’t think that’s resource heavy at all tbh

[lethal knoll]

I have no idea how heavy it can be

[visual tide]

is a 2018 mac modern?

[misty current]

i'm not saying modern computers can execute any calculation instantly but

[lethal knoll]

Alright, great 🙂

[misty current]

sure they can make pretty hard ones in matter of milliseconds

[lethal knoll]

I'll run it every 20 ticks and I should be good

AIght, thanks!

[visual tide]

sha4096 go brr

[misty current]

example, i had a plugin that had to check when a player entered or left a custom claim zone

there was like a claim block that had a certain radius

so on entity move i looped all of these claim blocks

[waxen plinth]

And you did spatial partitioning, right?

Oh boy

That's not good at all

[misty current]

checked the bounds

it was probably not the best way but with 50+ players it had a minimal impact on performancew

because all it did was basic math at its core

[waxen plinth]

It's O(n*m) with n players and m claims

[misty current]

more like O(n) where n is the sponges per each player movement

in worst case scenario

[waxen plinth]

Might not be terribly problematic until you realize that since the number of claims is directly related to the number of players, it's essentially O(n^2)

Talking about per tick here

Because player movement is processed once per moving player per tick

[misty current]

iirc player move events can be called multiple times per tick

so it might have been even worse

[waxen plinth]

And it's incredibly easy to set up spatial partitioning for that

[glossy marsh]

https://imgur.com/a/prM0SgJ

[misty current]

i'm not sure what is spatial partitioning tbh

[waxen plinth]

https://github.com/Redempt/RedLib/blob/master/src/redempt/redlib/region/RegionMap.java

Basically this

[glossy marsh]

I made a video to show what I mean. If you rename an enchanted golden apple the suggested name remains pink/purple, whereas if you rename an item with a custom name and a custom color the color will just change to white again. I was wondering if there was some kind of NBT tag which sets the color name of an item causing the golden apples name to remain purple when suggested

[waxen plinth]

Basically just a map for approximate location -> things near that location

[visual tide]

nope, that's hard-coded into the client for special items like enchanted golden apples

[waxen plinth]

So you can quickly determine what is near a location and do your extra checks from there

[glossy marsh]

😦

[misty current]

so it's like dividing the world in subsection

getting the subsection a player is in

[visual tide]

as i said you could listen for anvilPrepareEvent, if it's the item you want to keep the color on, strip all color off with ChatColor.strip and then recolor the stripped new name

[misty current]

and then checking the elements in that subsection

yeah that sounds much more efficient

[glossy marsh]

Yes, I'm thinking about doing this

[solemn aurora]

Hey everyone, I'm stuck on an issue regarding villager trades.
I spawned in a villager with custom trades (diamond for a book).
It does spawn and behaves like a normal villager but when I want to trade the screen shows up for a couple of milliseconds and then disappears.
Does anyone happen to know what might cause this?

[chrome beacon]

What version of Spigot?

[solemn aurora]

for 1.18

[spiral light]

maybe the trade screen will close if the villager has no job or smth

[solemn aurora]

I tried giving it a profession but then it just shakes it head

https://tenor.com/view/villager-real-life-minecraft-villager-long-nose-gif-16026583

I found the solution.
The vilager checks on spawn if there is a profession block nearby. If not it just reverts to a normal villager.
Somehow normal villagers are not allowed to trade anymore but by setting the experience to an arbitrary value it stays as the profession.

setting the level works too

[proud basin]

Anyone know if FileWriter creates a file when when you instantiate it?

[waxen plinth]

Doubt it, but check the docs

Why are you using FileWriter though?

[proud basin]

because it's the best

and

[waxen plinth]

I prefer nio

[proud basin]

I need to use it

[waxen plinth]

Files.writeString

[buoyant viper]

i believe it only creates once u call .write

[buoyant viper]

Files.readAllLines is a godsend

it does lack the ability to directly write bytes tho iirc

ig it makes up for that by having .newBufferedWriter

[waxen plinth]

Pretty sure you can write bytes directly but I could be wrong

[buoyant viper]

iirc theres no writesBytes or plain .write

im also just kinda browsing its javadoc rn

[dense heath]

This isn't spatial partitioning :thonk:

[waxen plinth]

How is it not lol

[dense heath]

It is a map, not at all even close to a partition tree

[waxen plinth]

It's mapping things spatially so you don't have to iterate over everything to find an object near a given location

The concept is the same

[dense heath]

Factually incorrect

[waxen plinth]

It's not a k-d tree but it doesn't need to be

[dense heath]

The implementation is not idea

[buoyant viper]

oh hmmm

[waxen plinth]

And yes, the concept is the same

[dense heath]

Nope xd

[waxen plinth]

To split things up based on approximate location to make it easy to find them

[dense heath]

It is log2(n)^2 * x * z insertion efficiency

Not even close to how good a k-d tree is

[waxen plinth]

x and z being what

[dense heath]

The size of the square you define

I didn't see any support for a third dimension in your implementation

[buoyant viper]

oh im dumb it's right there

[waxen plinth]

Yeah it uses x and z only since the y axis is so tight

[dense heath]

You should have support for y-axis anyways, but that's a separate issue

[waxen plinth]

But insertion is O(1)

[dense heath]

Definitely not

[waxen plinth]

How not

It determines where to insert, with simple division, O(1)

Then inserts into a set, also O(1)

[dense heath]

A hash set

The insertion time for hash sets and hash maps are longer

[waxen plinth]

Yes a hash set has O(1) insertion too lol

[dense heath]

That's bullshit

[waxen plinth]

Bruh

[hybrid spoke]

its not

[waxen plinth]

It's literally how it works I don't know what you want me to say

Look it up

[young knoll]

"For HashSet, LinkedHashSet, and EnumSet the add(), remove() and contains() operations cost constant O(1) time."

[waxen plinth]

Hashing an element is O(1)

And the array write is O(1)

So inserting an element into the region map is O(1)

[dense heath]

I got to go fact check this right now, I'm looking at the implementation

[waxen plinth]

Lmao

[dense heath]

I might actually be retarded

There is a chance here

[waxen plinth]

I have literally implemented these days structures before and it's common knowledge that insertion is O(1)

That's the entire point of hash sets/maps

[dense heath]

FACTUALLY INCORRECT

[waxen plinth]

This region map is not as precise as a k-d tree but it's good enough for the vast majority of use cases

[dense heath]

This is so factually incorrect

I have checked the implementation

[waxen plinth]

.-.

[dense heath]

You would expect the average insertion time to be O(1)

[hybrid spoke]

dont feed the troll

[waxen plinth]

Yes worst case is O(n)

[dense heath]

But the worst case insertion time will be O(n)

[waxen plinth]

Just like quick sort has a worst case of O(n^2)

[dense heath]

Always operate your assumption of efficiency on the worst case

[waxen plinth]

But you don't call quick sort an O(n^2) algorithm

You fucking dingus

[dense heath]

Yes I do

That's what it is.

[waxen plinth]

...

[dense heath]

Expected may be better *, but it is still at that level.

[waxen plinth]

Quick sort is only O(n^2) if it picks the worst possible pivot every single time

The odds of that happening for a large data set are so astronomically low

[dense heath]

but never zero

[waxen plinth]

Much like the odds of a hash collision on every element are astronomically low

If you're worried about that you should worry about me mashing random buttons on a keyboard and guessing your password first try

[dense heath]

Regardless, O(n) on the hashset, O(n) on the hashmap, x*z for the insertion on every single address

[waxen plinth]

Or getting struck by lightning whenever you go for a walk

Or a UUID collision every time you use UUID.randomUUID()

[dense heath]

Or having a Minecraft developer be a capable individual >:)

[waxen plinth]

We call it O(1) because that's what it's always going to be unless you got odds better than winning the lottery multiple times in a row

[dense heath]

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

[waxen plinth]

So please understand why you come across as insufferable when screaming "FACTUALLY INCORRECT" in the face of common knowledge

I'm going to call my region map O(1) on insertion because under all reasonable circumstances that's what it is

[dense heath]

I'll take the L and admit that I'm retarded with most of my claim, but I'm not going to set the fact down that what you have made is, in fact and reality, not a spatial partitioning algorithm.

You are inserting objects into a hashmap, that's not partitioning at all.

[waxen plinth]

If you have 100k elements in your HashMap, the odds of them all having colliding hashes and the runtime being O(n) is 1 in 100k^100k, an unfathomably small chance; you'd have better odds of picking a random particle in the observable universe and having it be the same particle 3 times in a row

And yes, this is a form of partitioning

[dense heath]

Factually incorrect

[waxen plinth]

It's one way of dividing up the space and mapping objects within it

[dense heath]

"wow look at these buckets! partitioning!"

[waxen plinth]

Yes, it's partitioning

Cry about it

[dense heath]

You're simply not partitioning anything at all

[waxen plinth]

It divides the space into equally-sized parts

It's partitioning

Chunks are a form of spatial partitioning

Quit being a pedant

[dense heath]

This is simply not some silly little thing, though

You're using a hashmap and calling it spatial partitioning

There is no elegance there

[waxen plinth]

How not

[dense heath]

That's not an algorithm, dude

[waxen plinth]

It doesn't need to be "elegant" to be spatial partitioning

And sure it is

[dense heath]

You're making a map wrapper

[waxen plinth]

Everything is an algorithm

Yeah

I am

[dense heath]

You have successfully made a map wrapper

[waxen plinth]

Again, cry about it, it's spatial partitioning

[dense heath]

Definitely not

[waxen plinth]

It's not like I'm claiming something super impressive

[dense heath]

Do you think Google is using hashmaps to position things in their pathfinding algorithms?

[waxen plinth]

I'm claiming to have made something which partitions a space by subdividing it

Which is true

[dense heath]

You haven't subdivided anything at all, though

[waxen plinth]

Yes I have

It subdivides worlds into equally-sized horizontal regions

[dense heath]

LMAO

No way that you're going to tell me using an integer coordinate system is subdividing the space

[waxen plinth]

Chunks work very similarly

And that's also spatial partitioning

[dense heath]

.

[waxen plinth]

It literally is lmao

[dense heath]

"The world is a partitioned space because of the atoms in it"

Same level brain assertion

[waxen plinth]

I'm grouping areas

[dense heath]

No, no you aren't

[waxen plinth]

PARTITIONING them into horizontal regions

[sacred mountain]

r

[waxen plinth]

Where do you get off?

Why are you being an elitist about the pettiest thing

This is one way of doing spatial partitioning

All you're doing is being an asshole here

[dense heath]

Okay, I'll play along here.

Let's say this is spatial partitioning

Give me all of the areas associated with a certain group.

[ivory sleet]

whats up

[waxen plinth]

Hi conclure

[dense heath]

For instance, I say that coordinates (10, 10) to (20, 20) belong to some string, "A"

[ivory sleet]

hello Red

[waxen plinth]

Care to tell this guy to quit being a pedantic condescending asshole?

[ivory sleet]

hmm well surrounding what?

[dense heath]

If your algorithm, in its current state, can give me all of the coordinates associated with the string "A" in comparable time to other real spatial partitioning algorithms, I'll PayPal you US$20

[ivory sleet]

or yk Ill just read for myself

[waxen plinth]

Good place to start

[dense heath]

Better place to start

[ivory sleet]

btw

[waxen plinth]

Sure

[ivory sleet]

big O notation only denotes worst time complexity

[dense heath]

^^^^^^^^^^^^^^^^^^^^^^

[buoyant viper]

@waxen plinth r u as sexy as redlib is?

[ivory sleet]

I mean bk that was to you

[waxen plinth]

You generally refer to average case when talking about these things but sure

[dense heath]

:thonk:

O(N) is worst time complexity for a hashset

[waxen plinth]

We never consider quick sort as n^2

[waxen plinth]

You tell me

[buoyant viper]

idk i like women

nice pillow

is that from uhhh

i forget the name

[ivory sleet]

Big O notation means worst time complexity
theta notation means average
omega notation means best

[waxen plinth]

Atla

[ivory sleet]

so saying average O(blah) is kinda wrong

[tender shard]

that's sexist

[buoyant viper]

what

[hybrid spoke]

This class offers constant time performance for the basic operations (add, remove, contains and size), assuming the hash function disperses the elements properly among the buckets

[ivory sleet]

anyways O(1) for insertion, contains and removal iirc

[waxen plinth]

Kinda but it's what everyone does because nobody wants to type theta

Ye

[ivory sleet]

idk why u'd say O(n) insertion

[quaint mantle]

Hey, Does anyone know what the DataWatcherObject id of customNameVisible boolean is? (1.18.1)

[buoyant viper]

wait red what r yu

[ivory sleet]

sure, the internal array must be resized from time to time

[waxen plinth]

He/him

[buoyant viper]

oh oki

[waxen plinth]

Well the technical worst case would be if all the hashes collide

So everything ends up in the same bucket

[ivory sleet]

yeah

[waxen plinth]

That would be O(n) but is so insanely unlikely that there's no use worrying about it

[ivory sleet]

yeah

[young knoll]

Are you saying I shouldn’t just return 1 for my hash codes

[waxen plinth]

lol

Technically a valid hash function

[ivory sleet]

insertion might be O(n) also if we consider bucketing

[buoyant viper]

yo mama so fat, sorting her is O(2^n)

[quaint mantle]

🙄

[waxen plinth]

Anyways the main argument was about whether my basic region map implementation is spatial partitioning

He says it's not when it's literally subdividing a space, which is what partitioning means

[dense heath]

He's trying to tell me that simply putting something into an integer coordinate system is subdividing it.

[waxen plinth]

You're dividing it up

Much like chunks do

And again, chunks are another form of spatial partitioning

[buoyant viper]

isnt subdividing dividing the divisions? 🤔😎

[waxen plinth]

I don't know why that is so hard for you to grasp

[quaint mantle]

How to check if a player is flying on elytra or with a fly?

[waxen plinth]

What

[dense heath]

We're bordering on spherical brain level ideas at this point

[waxen plinth]

Oh elytra

[buoyant viper]

how to tell if flight is isFlying or elytra

[waxen plinth]

isGliding vs isFlying

[quaint mantle]

thanks

[waxen plinth]

Look, you're just being so condescending for no reason. Grouping nearby objects together in equally-sized regions is spatial partitioning, and if the definition of partition doesn't convince you then I don't know what will. You're really getting on my nerves by being so pedantic about it, especially screeching FaCtUaLlY iNcOrReCt like it helps your case

[solid cargo]

anyone has an experience in the plotSquared API here? which event do i use to check if the player is trusted?

[tender shard]

event? there's some method for that

https://github.com/JEFF-Media-GbR/InvUnload/blob/master/src/main/java/de/jeff_media/InvUnload/Hooks/PlotSquared6Hook.java check this

I also have a class for PS4 and PS5

[solid cargo]

now tell me where lol

[tender shard]

check the class I sent

[solid cargo]

ok

[tender shard]

it uses reflection though

because I didnt know any better back then

[solid cargo]

my client is on p^2 v5 tho

same thing?

[tender shard]

then check the other class

as said I have classes for PS4, 5 and 6

[dense heath]

#help-development message

[waxen plinth]

That's the opposite of spatial partitioning

That would be a Map<String, Set<Location>>

Mine lets you get objects of an arbitrary type mapped near a given location

And I don't want your money

[dense heath]

Nope, it is apart of spatial partitioning

If I insert a box I ought to be able to figure out where the box is later

[waxen plinth]

A reverse map is a separate thing

[vale ember]

Required type:
capture of ? extends Event
Provided:
PlayerInteractEvent

whyyyyyyyyyyyyyyyy

[ivory sleet]

yeah areg

whats the code behind that

pretty sure we can solve it

[vale ember]

package com.aregcraft.delta.item;

import lombok.NonNull;
import org.bukkit.event.Event;

@FunctionalInterface
public interface EventConsumer<T extends Event> {
void handle(@NonNull final T event);
}

[ivory sleet]

and then?

[vale ember]

package com.aregcraft.delta.item;

import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NonNull;
import org.bukkit.event.Event;

import java.util.List;

@Getter
@AllArgsConstructor
public class TypeInteractionHandler {
@NonNull
private final List<EventConsumer<? extends Event>> eventConsumers;
}

[radiant estuary]

How can i get tools that work like the Elytra? they stop at durabilty 1 and are then unuseable?

[ivory sleet]

EventConsumer<? extends Event> makes no sense

[vale ember]

why

[ivory sleet]

well any class with a generic type parameter is a type of a type constructor

Lets say we construct the type EventConsumer<Event>

this type is different from EventConsumer<PlayerEvent>

(just as an example)

usually when we have consumers we are callbacking on a specific argument

in this case an instance of Event

if you have ? extends Event

it means any a capture of any subtype of Event

now if we had ? super Event it'd make more sense, as you'd be able to pass an EventConsumer<Object>

[opaque plaza]

is there a way to get the full nms source code with the mojang mappings

[ivory sleet]

if you have an EventConsumer<PlayerEvent> an instance of this type might do operations only the type PlayerEvent would support

so then its very risky to pass an object to an EventConsumer<? extends Event> as you don't know which subtype is the correct one

[quaint mantle]

how to check if the player is rotating the mouse?

[ivory sleet]

So your design might be a bit flawed in this case

[quaint mantle]

@ivory sleet

[ivory sleet]

PlayerMoveEvent maybe

idk if there are more suitable events for that tho

[quaint mantle]

I use PlayerMoveEvent

[ivory sleet]

alr

well check if the location's x,y and z are the same

[quaint mantle]

When I go, I get a message

[opaque plaza]

running build tools just returns me the one with the spigot mappings

[ivory sleet]

but if the yaw and pitch are different

[opaque plaza]

which is obfuscated

[ivory sleet]

what build tool do you use?

[quaint mantle]

thanks

[opaque plaza]

maven

[ivory sleet]

oh idk then

maybe elgar or mfnalex can help ya

[opaque plaza]

but I can use gradle too

[ivory sleet]

ok

then you'd stick with paperweight-userdev plugin probably

[eternal oxide]

--generate-source --remapped

switches for BT

[north trench]

i still do not know? can you help?

nothing works i am using PlayerInteractAtEntityEvent event

[lucid bane]

does this #help-development channel help kinda resourcepack problems?

[north trench]

Yes

[opaque plaza]

checking /work/decompile-latest still has the spigot mappings

[eternal oxide]

there are no spigot mappings in 1.18

[lucid bane]

I tried to make an gui, so i tried to add an gui-model to diamond_hoe and it kinda worked, but texture being darkened.

minecraft/models/guis/upper_section.json:
https://paste.md-5.net/agugizonap.json

minecraft/models/item/diamond_hoe.json:
https://paste.md-5.net/bubatejenu.json

[lucid bane]

i can't find why it darken like this

[sacred mountain]

it looks like the other gui is ontop of that gui

and the whole screen darkes

is that gui a texture? the diamond hoe one

[spiral light]

is this even server programming related ?

[sacred mountain]

because when you open your inventory maybe it darkens everything around it including the diamond hoe texture

[lucid bane]

i dont know what it acually means programming-related but
probably yes

[sacred mountain]

its not anythingn to do with plugins or code tho

[spiral light]

sad 😐

[lucid bane]

i made an gui-texture and links to diamond_hoe like this

[tardy delta]

how does this looks?
https://github.com/FourteenBrush/MagmaBuildNetwork/blob/main/src/main/java/io/github/FourteenBrush/MagmaBuildNetwork/database/Database.java

[proud basin]

How can I grab every single line in a text file with bufferedreader?

oh wait

nvm

got it

[tardy delta]

split it by \n would be my guess

[solid cargo]

how can i check if the plotsquared player is trusted?

[late sonnet]

get the trust list of the plot?

[solid cargo]

idk how to get the plot the player is in tho

[late sonnet]

https://javadoc.io/doc/com.plotsquared/PlotSquared-Core/latest/com/plotsquared/core/plot/Plot.html#getTrusted()

you can get the Plot using location https://javadoc.io/doc/com.plotsquared/PlotSquared-Core/latest/com/plotsquared/core/plot/Plot.html#getPlot(com.plotsquared.core.location.Location)

[mental moon]

What event gets called when a block is broken by forces other than the player? Like Water breaking a torch.
BlockBreakEvent and BlockDropItemEvent are only fired when the Player triggers them.

[misty current]

hey @wet breach, sorry for the ping but i wanted to ask where could I find a version of packetentityapi for 1.8. I have tried to use the latest legacy release i was able to find (0.7.2) but it won't launch because it has inside stuff from later versions. I'm asking because i saw on the spigot page that 1.8 is supported (ping me back when u can reply)

[mental moon]

I might have figured this out. Seeing if a EntitySpawnEvent (instanceof Item) can help me here

[woeful crescent]

does entity.remove() call entitydeathevent?

[mental moon]

I don't believe so

[woeful crescent]

if an armor stand is riding an entity

and the entity gets .remove()'d

what happens to the stand?

[mental moon]

i would assume it would be dismounted and left there, but it could also get deleted

[woeful crescent]

hmm

[mental moon]

check for passangers, dismount, then remove

[woeful crescent]

when tho

idk

[quaint mantle]

Well, not bad, however i'd get rid of plugin/config depenency. Instead, make your constructor accept data you actually need: password, username, database name, and such.

[woeful crescent]

i wanna set armor stands on entities without inserting a line after every time .remove() is called

that's not very dynamic

[mental moon]

something like if(ent.getPassengers.size != 0){ do a thing }

[quaint mantle]

Also, you shouldnt execute code in constructor like you do with insertQueryAsync - you just create the object

[woeful crescent]

but when? .remove doesn't call death event

[mental moon]

It would be a check before the remove. If you want it to call a death event you can instead do livingEnt.damage(9999)

or maybe there's a kill too

[quaint mantle]

Also, do not swallow exceptions: instead of crying in logger, rethrow it by wrapping in RuntimeException. If something went wrong, code should know about this

I also would remove insertQuery async at all. Database mamanger shouldnt throw async tasks by itself.

is there a way that online players can be hidden from tab complete and commands, so that even vanilla commands would not be able to target them?

[spiral light]

is there something to check (packets or api) if a player wants to move a horse while sitting on it for example

[spiral light]

you would need to use nms probably

[mental moon]

Last I remember Horse movement is clientside. If it doesn't fire from PlayerMoveEvent I can't think of where it'd come from

[quaint mantle]

Im definitely sure I would need packets but im not sure what would intercept commands or tabcomplete to make the player appear offline

[spiral light]

hmm sad ... thought an fake player as horse (horse is not fake, but despawned for player and instead the fake player is spawned) will work xD but the client does not want to control the player like a horse 😄

[spiral light]

tabcomple will be packets for sure.... that cmds work would be that you have to remove the player from all registrations in the server ... (thats a bad idea^^)

[quaint mantle]

hm, I guess I'll have to manually handle that with the command preprocess event then

[spiral light]

is it possible that even pigs are client side movement controlled ???
i cant move the pig(disguised as player) with a carrot on a stick

[echo basalt]

Steer_Vehicle packet

PacketPlayInSteerVehicle

Usually contains a forward and side movement inputs, space and shift status

You can then use the ControllerMove's a(float, float) method to strafe any entity as if you were controlling it

(1.12) ->

float forward = ...; 
float side = ...;
boolean jump = ...;
boolean shift = ...;

Player rider = ...;
Entity vehicle = rider.getVehicle();

if(shift) {
  rider.leaveVehicle();
  return;
}

net.minecraft.server.v1_12_R1.Entity nmsEntity = ((CraftEntity) vehicle).getHandle();

if(!(nmsEntity instanceof EntityInsentient))
  return;

EntityInsentient insentient = (EntityInsentient) nmsEntity;

ControllerMove move = insentient.getControllerMove();
ControllerJump jumpController = insentient.getControllerJump();
// ControllerLook look = insentient.getControllerLook();

move.a(forward, side); // strafe

if(jump)
  jumpController.a();

Will be similar for higher versions, just make sure that the ControllerMove's method takes in 2 floats, or its internals reference strafing

If you want to change the strafe speed, you need to access its e variable (often the 4th double) and set the value

Hope that helps @spiral light

[spiral light]

the packet helped a lot
thank you^^

[echo basalt]

Cheers

Horses will be quite buggy FYI

Seems like spigot handles them separate

[spiral light]

yeah there is no api i can see for setting the saddle O.o

[echo basalt]

Also slimes etc will need to have their ControllerMove instance set to something else if you want them to behave like regular entities

[echo basalt]

HorseInventory#setSaddle

Pig#setSaddle

[spiral light]

ah wow ... thank you, i had pig but horse has to be different of course ^^

[quaint mantle]

Does anyone here have experience with packages related to ClientboundSetEntityDataPacket?

I have an armor level and set the nogravity and customname and customnamevisible and the customname stuff doesn't work does anyone know a fix?

[spiral light]

isnt customname for chat ?

[tender shard]

?

[quaint mantle]

customname for a armorstand

[spiral light]

ah ok

[quaint mantle]

I set both correctly and it just doesn't work, yet it has the other properties but

[quaint mantle]

Thats a metadata packet, no?

yes

The armorstand is also spawned but without customname

[sacred mountain]

how do i make an event that when a player places a water/lava source it saves the location to a list and i can later remove the location and add more if i need

WaterBucketEvent(PlayerBucketEmptyEvent bucketEmptyEvent)

is that the right method

[hasty prawn]

It doesn't follow naming conventions but the Event you're using is correct.

[sacred mountain]

ok thanks

[hasty prawn]

Then just call bucketEmptyEvent.getBlock().getLocation() and that should be the location of the source block.

[sacred mountain]

i saw someone say that that would get the Exact location

and not the coordinates

[quaint mantle]

do you know the problem?

[hasty prawn]

What

Exact location of what

[fervent gate]

https://paste.md-5.net/oyowoxeras.java --> Main file
https://paste.md-5.net/vivajusaqe.java --> DataManager file
https://paste.md-5.net/necidevubo.bash --> Error log

I am getting the following error, all of the needed classes are in this message. Why am I getting the error? I tried putting the config inside of the jar file, but that didn't seem to work.

[young knoll]

The config should be in the same place as the plugin.yml

[fervent gate]

oh ok

[sacred mountain]

this look correct?

trying to get the location of a placed water bucket

or is that the face that the water is placed on, so the block below.?

[light parcel]

Does anyone know how to listen for events with MockBukkit?

[ivory sleet]

I believe like normal spigot

[light parcel]

Test class needs to implement listener then?

[ivory sleet]

its only the mocking of calling an event which might be different?

yeah

and for setup you'd register the listener in principle

and tear down you unregister it

[bitter fulcrum]

Does Spigot automatically map the Minecraft jar? If so what mappings does it use?

[ivory sleet]

it used to have those nms mappings

you can use mojmaps now

tho you're not allowed to distribute it iirc so if you're a plugin developer might be sufficient to only depend on mojmaps at compile time

[bitter fulcrum]

Am I able to use yarn?

[ivory sleet]

nope

or well

dont think anyone has taken the effort to implement such a plugin which would support it

[young knoll]

Doesn’t paper run mapped at runtime

[ivory sleet]

yeah

[young knoll]

Therefor requiring you to distribute mapped jars

[ivory sleet]

yeah it patches the binaries

or smtnfg

[visual tide]

is it possible to make a player have potion particles on the without them actually having any effect?

[ivory sleet]

sounds like you'd have to use packets for that

but prolly is since the visual effect is just rendered client sided

[visual tide]

yay

why can you not use external emojis here

sad

wanted to express my happiness to be working with packets

[young knoll]

You need to boost

[ivory sleet]

Hmm, I have an interface with a getter, in implementation A its nullable, but in implementation B its not nullable, do I annotate the getter in the interface with @Nullable still?

[quaint mantle]

IMO, yes

[light parcel]

Thanks, got it working, but I'm having to introduce another instance variable into the test class. Don't suppose this is avoidable? Ln61 getEvent() used to initialise ln43 tagEvent:
https://www.toptal.com/developers/hastebin/latodebeku.java

[young knoll]

Just uhh

[alpine urchin]

just do it

[young knoll]

Make it an optional so it’s not nullable either way

[ivory sleet]

hmm yeah

Ik checker qual got @PolyNull but meh

[alpine urchin]

i didnt read much context

but do it

[young knoll]

@dark thicketNullable

What

Gosh dangit

[ivory sleet]

well

you probably want to isolate the test class from the actual logic

like the test class shouldnt be a listener itself lol

lol

[young knoll]

@QuantumNullable

[light parcel]

Ah then I'm not sure how to get the "capture" the event in the test?

[young knoll]

It’s both null and not null until observed

[ivory sleet]

oh god lol

[ivory sleet]

well you just use PluginManager::callEvent to invoke an event

[lavish hemlock]

I believe IDEA can differentiate based on implementation but idk.

[visual tide]

bruh the only thing i can find on potion particles is how not to show them 😐

[ivory sleet]

hmm interesting

[visual tide]

maybe EntityEffect packet?

or is that something different

[ivory sleet]

class Test {
  Listener listener;

  void setUp() {
    listener = new MyListnrImpl();
    pluginManager.registerEvents(listener,plugin);
  }

  void givenEventInvocation_doesEventGetCancelled() {
    MyEvent event = new MyEvent();
    pluginManager.callEvent(event);
    assertTrue(event.isCancelled());
  }
}``` @light parcel for instance

tho that might actually test the event instead or well both parties actually

[dense heath]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/Particle.html ??

[ivory sleet]

a bit problematic if you wanna isolate your units

but yeah the way spigot's event system works with explicit types its hard to mock events

[light parcel]

But the test is supposed to be checking that this event is thrown by other conditions, throwing it myself defeats the points of the test

[ivory sleet]

yeah

in that case invoke the according mock methods

and assert that the event ran

or sth

[visual tide]

not sure you read what i sent
i want to show potion particle effects on a player

[ivory sleet]

depends if you're testing the listener or the event

yeah might wanna use a MockListener then

or sth

[dense heath]

I read it lol. Simply spawn the particles?

[light parcel]

Both I guess, I've got one event that triggers a second that I listen for - what's sth?

[ivory sleet]

something

well thing is

[light parcel]

oh lol

[ivory sleet]

you should separate it to 2 different classes

one class testing the listener with a mock event and one testing the event with a mock listener maybe

[light parcel]

Mm yeah it's probably a poorly designed test tbh

[ivory sleet]

well

bukkit and minecraft in combo with unit tests is kinda meh

but it works almost fine

altho its hard to always apply all practices to the letter given the environment

[dense heath]

Instead of unit tests, formally verifying the logic on your code is better

[ivory sleet]

we just have to assert certain things that arent gonna happen

[ivory sleet]

wym formally verifying? like manually?

because the entire point of using unit tests is to automate the process

and then whenever you add some new prod code to your system you run tests and check if everything still passes

[dense heath]

No, no, you can automate the formal verification process. You simply have to write the rules for the code once

Fuzzing is your friend :)

[ivory sleet]

oh you mean that

hows it better tho?

[dense heath]

It is mathematically impossible to break your code if it is formally verified to be correct

[ivory sleet]

is fuzzing the same as mutation tests?

because if its that then sure its not a bad way of testing

[dense heath]

Yes, fuzzing is a special type of mutation test

[ivory sleet]

ah right

well thing is

[lethal oxide]

Hello there! I am currently in the midst of an unworkaroundable error in my code involving remapped NMS, i have consulted many people and many other servers and if this doesnt work idk what to do then. My problem revolves around the Clientboundinfopacket class and it being ig build tooled improperly. i dont know the root of this error and have tried rebuilding my 1.17.1 build tools 5 different ways now and nothing has worked, along with trying various other work arounds. Here is the error and i would EXRTEMELY appreciate any help if it can be provided as i cannot continue development of this plugin i WAS excited for which would suck. Upon maven clean package building and artifact building with inltellij i receive this error D:\Coding\Intellij projects\DownedRust\src\main\java\me\art\downed\downedrust\BodyListener.java:5:43 java: cannot access net.minecraft.network.protocol.game.ClientboundAddPlayerPacket bad class file: /C:/Users/Blake K/.m2/repository/org/spigotmc/spigot/1.17.1-R0.1-SNAPSHOT/spigot-1.17.1-R0.1-SNAPSHOT-remapped-mojang.jar!/net/minecraft/network/protocol/game/ClientboundAddPlayerPacket.class class file has wrong version 60.0, should be 52.0 Please remove or make sure it appears in the correct subdirectory of the classpath.

[bitter fulcrum]

Is there a way to use unmapped?

[ivory sleet]

mutation tests can take considerably more significant amount of time to do

[drifting vault]

using protocollib, is there a way to cancel the digging sound of a specific block?

[ivory sleet]

so its not those tests you run after every function you write or sth

ofc depends if you do tdd or not

but yeah

[lethal oxide]

if anyone could help i would much much much appreciate that

[dense heath]

To be fair, for Minecraft, it is overkill af

[ivory sleet]

hmm maybe

[dense heath]

There are special use cases for it, like if you write an actual spatial partitioning algorithm to store your claims

[visual tide]

wrong java version

[ivory sleet]

I mean you can test your code regardless?

[visual tide]

build it with java 17

[lethal oxide]

been there done that

[ivory sleet]

just that I hate tdd (to a certain extent)

[main dew]

hi I make aspect plugin use AspectJ and I try load this when I eneable spigot
I should write other argument when I eneable server? java -jar -javaagent:C:/Users/MatDr/.m2/repository/org/aspectj/aspectjweaver/1.9.7/aspectjweaver-1.9.7.jar spigot.jar

[dense heath]

TDD is shit tbh

[lethal oxide]

sorry that was toxic but yeah i already tried that

[fathom cobalt]

how can I insert a BaseComponent or any of it's deriving classes into a book?

[ivory sleet]

well yeah I believe the theory and reasoning about writing tests is good

[dense heath]

Imo the only unit tests you should write for your code are the ones where you have special exceptions that should always be accounted for

[ivory sleet]

but tdd became a shit cult people commit to blindly

[dense heath]

I.E. you're doing address parsing and one of the parcels has a special format you'd like to make sure you follow and are able to parse

[ivory sleet]

Idk I usually write unit tests for anything with io and networking todo as well as parsing yeah, and possible concurrency

but for actual design, unit tests is a big no

[visual tide]

i write unit tests when it doesnt work

😐

[drifting vault]

i would like my question to be answered if thats alright

[dense heath]

Link it

[drifting vault]

here

[ivory sleet]

well I believe functional tests and those tests which aren't specifying concrete units are much better as they don't break every other second you decide to change the concretion

[dense heath]

Have you used protocollib before?

[drifting vault]

somewhat. i have used the sample code to disable all sounds but i can still hear the walking and digging sounds

new PacketAdapter(getPlugin(), ListenerPriority.NORMAL,
                PacketType.Play.Server.NAMED_SOUND_EFFECT) {
            @Override
            public void onPacketSending(PacketEvent event) {
                // Item packets (id: 0x29)
                if (event.getPacketType() ==
                        PacketType.Play.Server.NAMED_SOUND_EFFECT) {
                    event.setCancelled(true);
                }
            }
        };

[dense heath]

Me, breaking every unit test I have by restructuring my entire codebase ):

[ivory sleet]

yeah

[quaint mantle]

i write unit tests because my pc cant handle a minecraft + minecraft + intellij idea opened at the same time.

[ivory sleet]

and then there's the "I want to extract a class"

[dense heath]

Solution: buy a better computer

[quaint mantle]

Such an easy and reliable solution

[dense heath]

Great. Here are all of the available packet types. https://github.com/dmulloy2/ProtocolLib/blob/master/src/main/java/com/comphenix/protocol/PacketType.java

I would recommend browsing through them first to see if any catch your eye. Particularly, this section should help you https://github.com/dmulloy2/ProtocolLib/blob/master/src/main/java/com/comphenix/protocol/PacketType.java#L103

[dense heath]

Me when I want to extract a class

Real vim hours

[drifting vault]

NAMED_SOUND_EFFECT

[ivory sleet]

lol

[dense heath]

Alright, any other than that which you think might trigger a sound?

[drifting vault]

its probably entity_sound

for walking and digging?

[dense heath]

Probably. Give it a shot!

[dense heath]

Correct. It is very easy, and very reliable.

I have never paid for something and not received it.

[ivory sleet]

the reliability is probably not the issue

[dense heath]

Simple solution: make or have money

[quaint mantle]

simple

[young knoll]

poor = !poor

[dense heath]

Very. Are you of legal working age in your area?

[quaint mantle]

no

[visual tide]

any1 know what the boolean in the ClientboundSetEntityDataPacket constructor is?

[dense heath]

Simple! Wait until you're of legal working age in your area.

[lethal oxide]

new problem how do i make this bat @echo off IF NOT EXIST BuildTools ( mkdir BuildTools ) cd BuildTools curl -z BuildTools.jar -o BuildTools.jar https://hub.spigotmc.org/jenkins/job/BuildTools/lastSuccessfulBuild/artifact/target/BuildTools.jar set /p Input=Enter the version: || set Input=latest java -jar BuildTools.jar --rev %Input% --remapped pause not use java 16 and use 17 instead, bc i dont even have 16 on my pc as a file and dont know why its still using it

[dense heath]

Send the class file

[quaint mantle]

Unit tests is a good practice right

[visual tide]

wat

[ivory sleet]

hmm to a certain extent, the reasoning behind writing tests is not invalid

[dense heath]

Point at a specific java executable file instead of using the one in the PATH variable

[visual tide]

if it wasnt obfuscated i wouldnt have asked and looked myself

[ivory sleet]

however practices like tdd is imo going in the wrong direction

[dense heath]

I specialize in deobfuscating code

[dense heath]

Send the class file for the packet you're unsure about

[lethal oxide]

so im assuming i woyuld use this line "C:\Program Files\Java\jdk-17.0.1\bin\java" -jar BuildTools.jar --rev 1.18... BUUUUTTT i wanna use the buildtools bat i have so where in that bat would i put that line to make it reference that

[dense heath]

???

Don't you:

java -jar BuildTools.jar --rev %Input% --remapped

[lethal oxide]

yeah but i need to point to the java jar somewhere in there right?

to run java 17

like u said

[dense heath]

Wait, hold on, I think I'm missing something here

Are you saying that you don't have Java installed on your PC, and because of this you are not able to run the java executable file?

[lethal oxide]

pretty kucvh i have jdk 17 installed, and dont have jdk 16. but for some reason running that bat uses JDK 16

[young knoll]

You replace ‘java’ with the java install path

[lethal oxide]

and i could just point to java 17

ok

that worked

thanks

[dense heath]

Wait what? Isn't that what you already said? xd

"C:\Program Files\Java\jdk-17.0.1\bin\java" -jar BuildTools.jar --rev 1.18...

[lethal oxide]

i worded it awfully lol

sorry for that

[dense heath]

You're vibing lmao

[lethal oxide]

now we just wait and see if this actually fixes the original problem

[lethal oxide]

which is this

[dense heath]

When are you getting this error?

[vague swallow]

How can I check a specific inventory slot for an item?

[dense heath]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/Inventory.html

[misty current]

i've probably found one of the strangest bugs ever

i have a custom enchant that plays a lightning bolt packet

[dense heath]

People say this before showing code with errors in it lol

[misty current]

and when i swap to peaceful and back to normal the packet (which is just sent to the clients) puts fire in the world

this is the code

sec

Location loc = wrapper.getVictim().getLocation();
wrapper.addPureDamage(level * 0.2);

Utils.playSound(Sound.AMBIENCE_THUNDER, 1, 1, wrapper.getAttacker(), wrapper.getVictim());
PacketUtils.playPacket(new PacketPlayOutSpawnEntityWeather(
        new EntityLightning(
                ((CraftWorld) loc.getWorld()).getHandle(),
                loc.getX(),
                loc.getY(),
                loc.getZ(),
                false,
                false
)), wrapper.getAttacker(), wrapper.getVictim());

(1.8)

[young knoll]

Why a packet

[misty current]

because else it places fire on the ground

which i don't want

[young knoll]

Did strikeLightningEffect not exist in old.old

[dense heath]

Go into the EntityLightning constructor you're calling

[vague swallow]

I can't find it

[dense heath]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/inventory/Inventory.html#getItem(int)

[misty current]

oh sht

ok i saw it

[dense heath]

Let me guess, it actually spawns the lightning bolt into the world? xd

[misty current]

yeah the 4th param should be true

and weird enough it depends on difficulty

[dense heath]

That's gaming!

[misty current]

something i didn't know about minecraft i guess lol

[young knoll]

I’ll take that as a no

Dangit 1.8

[misty current]

dont think so

what class is it from

[young knoll]

World

[misty current]

lemme check

oh yea its a thing

hm

something i didn't know +1

i've tried googling about it and the only answer i've found was about packets

not like it makes any differences for me as it's a private plugin that won't run on modern versions

[spare marsh]

Hi, is it possible to pass an InventoryClickEvent to another class?

the whole event

[young knoll]

Sure

Just pass the object

[spare marsh]

have a listener and if it is a certain inventory, pass it on to another class to manage the logic

[misty current]

yes, put it as a paramter for the constructor or whatever

i have a wrapper that wraps attack events

i'll send the class

[spare marsh]

Well I only need it to handle the logic I don't really needed inside the class so I don't want to put it in the constructor

[misty current]

um it's a bit big

[spare marsh]

It is not very important

wait why on the constructor if the event can change its data?

[misty current]

yeah anyways you can pass it as any object

[spare marsh]

I did but for some reason it won't work.

Is putting the annotation necessary for the method I'm passing it on to?

[young knoll]

No

[misty current]

@EventHandler
public void onEvent(InventoryClickEvent event){
    manageEvent(event);
}

private void manageEvent(InventoryClickEvent event){
    event.setCancelled(true);
}

[spare marsh]

To send it I listened on the actual listener class and then sent it to another class if it is a certain title but for some reason, it won't work.

Something similar to that but it won't work.

@EventHandler
    public void onClick(InventoryClickEvent event){
        if(event.getView().getTitle().startsWith( Resources.colorMessage("&8Edit member &e≫"))){
            getMemberGUI().applyLogic(event);
        }

    }```

[misty current]

are you sure the event was called?

did you register the listener

[young knoll]

And does your if statement pass

[misty current]

^

does strikeLightningEffect play the sound

[young knoll]

Try it

[fleet imp]

how do i define a list w/o it throwing 15 errs and warnings at me

[spare marsh]

Yes, the event is cancelled in that same method but I removed it just now, but yes the event is cancelled so when I click it cancels. I am not sure it is passing the logic part tho.

[misty current]

oke

• 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.

[spare marsh]

Yes the listener is registered and running just not passing it right for some reason

[proud basin]

how can I check if a player is in liquid such as water, lava etc...

[misty current]

it doesn't, just checked the nms class

[spare marsh]

Check the block's type maybe?

[young knoll]

Probably the best way

[misty current]

you need to call t_() that handles logic and also sound

[young knoll]

I think either block or material has an isLiquid

[misty current]

also i love that they have 3 methods that are completely empty

with no implementations anywhere

lol

also yea apparently lightning can only leave fire if the difficulty is above easy

[upper niche]

ah yes
thank you terminal for giving such a useful error report

[19:05:03] [Server thread/INFO]: [pvpPlugin] Enabling pvpPlugin v1.0
[19:05:03] [Server thread/ERROR]: Error occurred while enabling pvpPlugin v1.0 (Is it up to date?)
java.lang.ArrayIndexOutOfBoundsException: null
[19:05:03] [Server thread/INFO]: Server permissions file permissions.yml is empty, ignoring it

i really dont wanna have to test every place that im using an array or List but it seems i might have to

[ivory sleet]

Well

It’s during bootstrap

So that should narrow down where the error origins from a significant amount

[upper niche]

i mean i guess?

[ivory sleet]

It’s also strange no stacktrace is printed unless someone just decided to print out the error message of the exception instance

Or sth

[upper niche]

theres so many things i initialize at startup that its like saying "instead of looking in the entire ocean, its somewhere in the mariana trench"

[ivory sleet]

Wat

[upper niche]

im not printing any errors currently

[mental moon]

Anyone know how to grab the base64 string off of a Player Head item?
I have no issues using the PersistentDataStorage on the Tilestate when it's a block, but I'm having an issue that prevents me from getting that tilestate data before it becomes an item.

[ivory sleet]

Vhoyd since you seem to be a lot more knowledgeable than me I can rest assure you that you’ll figure it out yourself

[upper niche]

lol
even if i did have knowledge i definitely dont have the wisdom

what even is knowledge
all i know is stackoverflow and ctrl c/v

[ivory sleet]

A good starting point is to share the code, if you’re comfortable with that btw

[ivory sleet]

Pretty sure you need to reflect the CraftSkullMeta instance

[upper niche]

i mean i can do that but theres just so much inefficient code to dig through
i dont want to be the cause of anyone suddenly finding themselves vomiting

[ivory sleet]

That’s their own fault then

[mental moon]

I'll look into reflection. Thanks

[ivory sleet]

Yeah well reflection should be trivial if you know your Java but I think google got some info on this, at least when I googled it tho that was some time ago

[mental moon]

I've managed to avoid reflection for a long time until now 😅

[ivory sleet]

Yeah well

It’s basically that you can do fun stuff with your java classes at runtime

[upper niche]

lmfao nevermind
the first method i threw a try catch around for error printing was the method causing the issue
now i just have to figure out why

oh cool

the stacktrace was actually logged

it just wasnt printed for some reason

lets go figured it out
i pulled a stupid
changed how a custom inventoryholder was loading so it filled the empty inventory slots with glass panes on initialization but left in another line that did that again
the loop started with the inventory's firstEmpty() which naturally in the second time since it's full would be -1
i am pepega

[lethal oxide]

tried and didnt work

now what

[sudden reef]

about this

I figured it out by..

Testing a bunch of things

it appears that for some reason

It's not enough declaring it 1 time

        obj.getScore("test-player").setScore(20);
        num =  obj.getScore("test-player").getScore();
        console.sendMessage(String.valueOf(num)); //says 20
        obj.getScore("test-player").setScore(55);
        console.sendMessage(String.valueOf(num)); //20
        obj.getScore("test-player").setScore(20);
        console.sendMessage(String.valueOf(num)); //20
        sendConsole("scoreboard players set test-player output 10");
        console.sendMessage(String.valueOf(num)); //20

this, wont work.

obj.getScore("test-player").setScore(20);
        num =  obj.getScore("test-player").getScore();
        console.sendMessage(String.valueOf(num)); //20
        num =  obj.getScore("test-player").getScore();
        obj.getScore("test-player").setScore(55);
        num =  obj.getScore("test-player").getScore();
        console.sendMessage(String.valueOf(num)); //55
        num =  obj.getScore("test-player").getScore();
        obj.getScore("test-player").setScore(20);
        num =  obj.getScore("test-player").getScore();
        console.sendMessage(String.valueOf(num)); //20
        sendConsole("scoreboard players set test-player output 10");
        num =  obj.getScore("test-player").getScore();
        console.sendMessage(String.valueOf(num)); // 10

this does

Any suggestion?

I'm thinking of doing a function

That can be called num() or something like that

And each time it's called it returns a new num

ig that could work

oh wait

I think i have to update the score not the num

let's test realquick

ok yeah it's the num

[proud basin]

How can you get a players mc version?

[subtle folio]

Im trying to make a combat log, java @EventHandler public void onDamage(EntityDamageByEntityEvent e) { if (e.getDamager() instanceof Player && e.getEntity() instanceof Player) { Player p = (Player) e.getDamager(); Player killer = (Player) e.getEntity(); combatLog.put(p, dur); combatLog.put(killer, dur); p.sendMessage(ChatColor.GREEN + "You have been added to combat log."); killer.sendMessage(ChatColor.GREEN + "You have been added to combat log."); } } But whenever I hit someone, I never get the message you have been added to the combat log

[sudden reef]

wait what

it's not the fault of

the scoreboasrd

with
int num = (int) Math.floor(Math.random()*(50-1+1)+1);
it happens the same

[sterile token]

Hello! Anyone know any good website for learning about syncronized methods?

[ivory sleet]

I mean it’s really simple

one thread at a time can run the method

[swift adder]

how would i implement both listener and commandexecutor in the same class?

[ivory sleet]

class X implements CommandExecutor, Listener{…}

[swift adder]

OH YES!

How could I forget that

Silly me

[sudden reef]

ok nvm

[ivory sleet]

Lol no worries

[sudden reef]

I got really confused

this is just like this

[lethal oxide]

Great yet another un finished project due to a major unfixable problem

Time to put this one in the archives and start something new ig

[ivory sleet]

Or fix your issue?

[swift adder]

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if (command.getName().equalsIgnoreCase("stats")){
            if (sender instanceof Player){
                Player p = (Player) sender);
                int value = stats.get(p.getPlayer());
                p.sendMessage(stats.get(value + " You got this many blocks"));
            }
        }
        return false;
    }```
Basically I want it to tell the player the Integer in the hashmap.

```java
HashMap<Player, Integer> stats = new HashMap<Player, Integer>();```

could anyone help?

[ivory sleet]

What the

First of all you can remove the redundant getPlayer() method

[swift adder]

That was an accident

That auto did that and just saw it right now

[ivory sleet]

But yeah you probably want to do something like
sender.sendMessage(Integer.toString(map.get(player));

[lethal oxide]

I don’t know how and apparently a ton of people don’t know either

[ivory sleet]

turns an integer into a string oofergang

[ivory sleet]

Can you link me to the original post

not sure which one but it needs something and it aint telling me what

could you elabrote why?

[young knoll]

Because you defined it as such?

[swift adder]

what's wrong with it?

if it works does it's fine aint it?

[young knoll]

It’s not descriptive

[lethal oxide]

Sure

[ivory sleet]

oofergang depends on definition of wrong but the name p itself doesn’t tell a lot about where the variable comes from, what it’s intent is and so on

instead of repasting your code just wait

You need to add mavenCentral() as a repo

[dusk flicker]

presume its cause maven central isnt listed

Also why depend on both api jar and the real jar

[dusk flicker]

nms

obviously

[ivory sleet]

Well isn’t the real jar sufficient for that?

[young knoll]

Doesn’t spigot already have gson

[dusk flicker]

thought it did

[ivory sleet]

Okay artificial

[young knoll]

Actually

Minecraft itself has gson

[dusk flicker]

my fork pulls gson from minecraft yeah

[ivory sleet]

I am convinced your project can be rescued if we use gradle @lethal oxide so if you’re willing to commit yourself to gradle then sure

[ivory sleet]

Btw incognitostaff how’s server rolling

[dusk flicker]

actually good

finally finished the core

[ivory sleet]

Delightful

[dusk flicker]

gonna rebrand under a new name and finally upgrade to 1.18.1 or whatever latest is, and get a survival server up first

[ivory sleet]

Ah noice

[dusk flicker]

As for v1 of the core some stuff isnt it in, mostly just punishments and vanish stuff, but that will be in post release

[ivory sleet]

Open source for core?

[dusk flicker]

trust me you dont want this open source

Can I get a server UUID?

Server uuid?

[analog prairie]

Because my plugin needs a database

make a uuid then
