[lavish wing]

Yeah, there s no spigot for 1.3.2
But spigot contains bukkit repo, which has 1.3.2

[sly topaz]

but my question is, why would you want Bukkit for 1.3.2

[lavish wing]

I have very big community for these versions

And I need to make my own fork to fix a lot of bugs and expolits

[sly topaz]

it didn't have much of an ecosystem back then, and all the plugins that support that version are probably lost to time. Chances are you are going to have a better time just running LegacyFabric which has an active community (very small, but active nonetheless)

[lavish wing]

I m using my own plugins (excluding CoreProtect)

Never heard about LegacyFabric, will check it later

[sly topaz]

welp, if you already have plugins developed for that version then it'll be a chore to port

so you're stuck with Bukkit I guess

[lavish wing]

Does LegacyFabric need custom client?

modded*

[sly topaz]

it is just fabric, but for legacy versions

fabric can load mods both on the server or the client, what determines if you need a mod on the client side as well is just whether you do something that's out of the scope of the vanilla protocol

[lavish wing]

I got it. Then it's better to use bukkit, my players using forge and vanilla clients

[sly topaz]

I don't think you understood what I meant. You don't need a modded client as long as you don't do anything that would break the protocol

[lavish wing]

oh

[sly topaz]

that's pretty much what plugins are in the end, server mods

[violet wave]

Will spigot 1.21.11 be completely embracing mojang mappings or will it be keeping custom spigot names?
I hope for the former.

[shadow night]

I don't see a reason to stay with spigot names

This goes on for about.... an hour or two.. Any big thoughts about this?

[eternal oxide]

Asynchronous chunk updates!

you have a bad plugin. Or one which is not compatible with Spigot

[wet breach]

they are running a modded client

I assume they have two types of servers. One forge and another spigot and connected to the one they thought was forge

[slender elbow]

huh

[wet breach]

a mod that is known for causing that specific error is Better Compatibility Checker

[sonic goblet]

I see, it says "Forge Server Log" but we only have a Spigot server and I've been running the same plugins for ~2 years now. Nothing new.

[wet breach]

you sure you don't have a modded client?

[sonic goblet]

Like that player is a modded client joining?

[wet breach]

There is only two likely things causing that error. Either they have a modded client or their player data is corrupted

[eternal oxide]

Its a server side error about an Async world modifcation. A modded client can not do that. Its a plugin not compatible with Spigot. Likely a worldguard for paper or something silly

[wet breach]

a modded client indeed can do that and I just told you a mod that causes that error

[sonic goblet]

I see, It's concerning that they were able to bring the server to a halt with that. I had to restart it completely

Essentially a ddos lol

[wet breach]

Yeah corrupted player data wouldn't cause the server to halt

it would just cause the player to not be able to join along with that error

a modded client can indeed cause a server to do weird things sometimes and thus why you should invest in packet inspection related things

Server does alright most of the time, but sometimes not good enough

also, you can do nefarious things sometimes with just packets alone so always good to have packet inspections anyways lol

[young knoll]

How does a modded client trigger a server to modify the world async

[wet breach]

the server isn't trying to modify the world async, its trying to load/spawn the player in

but it can't because the data the client is sending is not correct

[slender elbow]

lol

[slender elbow]

yeah from what i can tell this is just a good old spigot bug, enabling the code of conduct just triggers that on spigot, gj

[wet breach]

the code of conduct is doing that?

guess, I should make note of that as something else to cause that error that is quite vague

[sonic goblet]

That’ll do it lol, ty for looking into it

[wet breach]

well now you also know some other things that would cause it too lol

[sonic goblet]

Ya haha

[wet breach]

well, now I have that added to my notes

[mortal hare]

honestly i think im ditching intellij in favour of just vscode

eclipse jdts lsp server is more than enough for me and i do most of the things in cli (like maven or gradle tasks) anyways

[quaint mantle]

honestly i think im ditching vscode in favour of nvim

[mortal hare]

nah

that's too far for me

the reason why its too far is not because of nvim's nature of being cli, but because its not popular enough to get first class support of LSP's

[quaint mantle]

Honestly I sometimes use mouse instead of memorizing a key in nvim

[mortal hare]

all LSP's nvim provides in extensions are mostly ports from vscode

thus they work less optimal than they would on vscode

also vscode can be run in the cloud

https://vscode.dev

its nice to have quick notepad in the cloud just to do configuring or replacement logic with regex

[mortal hare]

why do people not write assert in java? I know that there's unit/integration testing but having something something like this allows to produce debug builds where you can easily reproduce the bug sounds... awesome?

i feel like it should be supplementary to the unit tests

[idle condor]

im trying to detect a right click but no matter what i do it doesn't work anyone got any idea?
Paste Dev Link

[eternal oxide]

assert does nothing at runtime

^ not the correct place to advertise. Post it on teh spigot site

[mortal hare]

exactly and that's what's powerful about it

its awesome for cases where there might be a bug due to impossible case (like nullability, invalid state, etc.)

by adding asserts for invalid states, you can produce stack traces with a debug for a cases which might be not needed if the behaviour was correct in a first place

public static Email from(final String address) {
    assert address != null: "Provided address argument is null";
    ...
}

lets say someone passes null into that method, you get github issue mentioning some kind of regression

you ask the OP to enable assertions and produce a stack trace

that like saves a lot of debug time just by enforcing strict checking which might not exist in production in a first place

it doesnt replace unit or integration tests

it adds a layer on top of them

to allow for easier manual testing

[modest vine]

ok

[mortal hare]

package lt.gathertime.server.value;

import java.util.Objects;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public final class Email {
    private static final Pattern PATTERN = Pattern.compile("\\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,}\\b", Pattern.CASE_INSENSITIVE);
    private final String value;

    private Email(final String value) {
        assert value != null;

        this.value = value;
    }

    @Override
    public String toString() {
        return this.value;
    }

    @Override
    public boolean equals(final Object value) {
        if (this == value) return true;
        if (!(value instanceof Email email)) return false;
        return Objects.equals(this.value, email.value);
    }

    @Override
    public int hashCode() {
        return Objects.hash(value);
    }

    public static Email from(final String value) {
        Objects.requireNonNull(value, "Email address value cannot be null");

        Matcher matcher = PATTERN.matcher(value);
        if (!matcher.matches()) {
            throw new IllegalArgumentException("Email address value is not of valid format");
        }

        return new Email(value);
    }
}

for example lets look at this email class. Public API (static smart constructor method) checks for nullability, but internal implementation uses assertions just for development purpose only to debug something in case there might be a need for at runtime.

[thorn isle]

I agree, asserts are an underutilized feature

[mortal hare]

this is a simple example, but if you lets say have multiple smart constructors with different varying levels of impl, this can save lots of debug hours

[thorn isle]

My guess is that people avoid them because as newbies they're told to never use asserts

In the same way we often hear "static bad" here

Both are tools for their jobs but you have to decide where to use asserts vs exceptions judiciously, and it's not a judgement call that's easy to explain to a beginner

So you end up telling them to just not use asserts

the other part is that, if you've bothered writing up validation logic, even if it's just for your internal affairs and "shouldn't" be needed outside of testing, you might almost as well just keep it there outside of testing anyway

the only downside is there being a performance impact from the actual validation logic, which in some cases can be negligible even for relatively hot code

e.g. that null assert on the email might as well be replaced by an exception, and the behavior of the program would only improve or remain unchanged at worst, never degrade

specifically, someone introducing the regression would have the code fail-fast immediately without the need to tell the end user to enable assertions

so although i do use asserts, i only usually use them for very hot spots, or for complex validation checks that'd have a real world impact on performance if shipped to prod

[mortal hare]

well yeah the cost of statements is neglibible on production, but i see it more like a semantic highlight for a developer too. If i know that something is exposed public, i use if statements with exceptions, if something that's internal that might go bad, i just use assertions just because it instantly implies for me that hey, theres might be the bug with the code you're looking at and not from some external source misbehaving

[thorn isle]

that's valid as well

[mortal hare]

it allows me differenciate internal misbehavings from external ones

[thorn isle]

there's never a clear-cut best way of doing these things; when in rome

[mortal hare]

iirc it also gives some sense to the IDE's of what data needs to be passed, so if you have private methods, it can also help the IDE catch the bugs for you

but so does annotations but annotations are less flexible to the demands of the domain though

[thorn isle]

one funny thing i use assert for it static flow control analysis

[mortal hare]

there's @Contract in jetbrains but who tf uses that and its very hard to really write them properly

[thorn isle]

it's a bit backwards, but suppose you have a bunch of if else spaghetti and other flow control, and you want to statically ensure that e.g. a != b, a and b being values modified somewhere within the flow control in easily unintuitive ways

[mortal hare]

that's a cool exploit for an IDE hinting lmao

i'll take that in mind

[thorn isle]

add the condition as an assert, and if it shows up with a warning saying "a != b is always true", you know your logic is right 🤡

the downside is that now you have a warning in your code

[mortal hare]

that's actually so smart

[quaint basin]

How should I create an RTP plugin? If x can be the minimum to the maximum value in the world, won't that use a lot of disk space/load many chunks?

[thorn isle]

what now

i'm not sure what you're asking exactly, but the way how rtp plugins typically work is by picking a random position, validating it, and retrying it if it isn't valid

depending on how strict your validation is, this can require few or many chunk loads

[quaint basin]

But is this random location between the minimum and maximum x and the same for z?

[thorn isle]

if it's a truly random tp, sure; personally i use a ring with a gaussian distribution tapering off the farther out/in you go from the ring

use whatever distribution fits your use case

[quaint basin]

wdym

[thorn isle]

i mean i don't pick a position from an uniform random distribution

some locations are more likely than others

[quaint basin]

In that case, I think I need to make the scenario that covers the entire world because, since it's going to be a resource-based world, it's good to spawn in a place that has resources and hasn't been explored yet (although this world will be reset daily)

[thorn isle]

if this is vanilla, i'm not sure if that's necessary; even if one or two players chop trees or mine ores, the area won't be completely exhausted

[quaint basin]

yea it is vanilla

[thorn isle]

if you really want to avoid sending players to locations that players haven't visited already, you can keep track of the areas where players have gone and check that in your location validation logic

do it asynchronously and ahead of time and you won't have to delay the teleport for the search

[quaint basin]

I didn't understand why async

Ah, right, I understand now. It's to perform the verification in a "single tick" - in this case, there is no tick because it's async

[thorn isle]

and if the world is large enough, a purely random distribution is probably good enough; the chance that any two players get sent to the same location is fairly low

[quaint basin]

Is there a risk of killing the async thread, even if the probability is low?

If I implement this validation using a while loop logic (as you're suggesting, but async) instead of splitting the validation into different time points

In my view, I can kill the async thread even if the probability is low

[thorn isle]

kill?

[young knoll]

Just make the world smaller and reset it often

[quaint basin]

the thread sleeps for enough seconds to kill the thread

[thorn isle]

threads don't die by sleeping

either way, i would use an ExecutorService rather than a while loop in a dedicated thread

[quaint basin]

So if I have a while look loop that takes 5 minutes to iterate, the thread doesn't die

[thorn isle]

this way thread lifecycles aren't your problem and even if they "die" from being idle in the executor's thread pool, the pool will create new ones on demand

[quaint basin]

I think that's overcomplicating things

[thorn isle]

threads die when

• the jvm dies
• another thread kills it via the deprecated kill/stop methods
• an uncaught exception reaches the top of the call stack

[quaint basin]

I think it's simpler to just validate each tick in the main thread and try for a valid location per tick

[thorn isle]

none of these should happen in normal operation

[ivory sleet]

@mortal hare a problem w assert is that it yields AssertionError not sure if that was mentioned

well it’s both a problem and a benefit depending on how u look at it I suppose

[thorn isle]

if it's used what it's supposed to be used for, it's a benefit

errors typically shouldn't be caught, so an assertionerror will terminate whatever is going on

[quaint basin]

I think this is bad because a person can go to RTP 10 times and not have done anything in all 10 of those times

[thorn isle]

aside from actually logging players breaking ores/harvesting resources in areas, there's no way around that

it does guarantee, however, that the area a player teleports to is untouched

the downside is that if you don't reset soon enough and your world is too small, you may completely run out of valid destinations

but again, i think just throwing everybody into purely random locations within a range is good enough; it's fairly unlikely for two players to teleport to the same place

[quaint basin]

What I was initially going to do is set the location to x = minX of the world + random.nextInt(maxX - minX + 1). The same for Z. I don't know if this will cause a high resource overhead due to spawning the player in very different locations

[thorn isle]

that looks like a purely random distribution, i.e. an uniform distribution yes

[quaint basin]

This is because in small ranges there is still a probability that 2 players are loading the same chunks but in different caves and thus mining different ores. But with very large ranges, it's the scenario where more chunks are loaded per tick in the world

[thorn isle]

i don't expect the distribution itself to have a large effect on performance; chunk loading is chunk loading no matter which order you do it in

[quaint basin]

So you don't see a problem with RTP with the range I mentioned?

[thorn isle]

if your validation fails, it may be cheaper to pick a position to retry with somewhere near the first, but i wouldn't this to be very significant

[quaint basin]

yea this is smart

[thorn isle]

what i do in my rtp plugin is i have a whitelist of biomes i teleport players to

computing the biome of a location can be done from noise asynchronously, so the first validation step occurs entirely off of the main thread

from there iirc i take a chunk snapshot of the location and try to find a valid position within the snapshot

if there isn't one, i try elsewhere

[quaint basin]

In my case, I won't have a biome whitelist, so I don't need that. I don't think a biome whitelist is necessary

[thorn isle]

well

do you want your players to teleport into an ocean?

no trees to chop there; bad start

[quaint basin]

In that case, I would check the highest block to see if it block is water at a random location

[thorn isle]

that requires a chunk load, which must be sync, and is slow

[quaint basin]

A biome can contain water and not be of the ocean type

[thorn isle]

checking the biome from noise is orders of magnitude faster

yes, you still need to check for water

but checking the biome will reduce chunk loads by about half, considering about half of the world is oceans

[thorn isle]

same applies to a lesser extent to deserts

[quaint basin]

never heard about noise

I'll see how I can do that

[thorn isle]

it's what minecraft generates its terrain from

[ivory sleet]

Yea and for that reason it’s also a shame that it’s only enabled through a flag suggesting you have a different set of errors in prod vs ur test/dev env (which is kinda why it sucks)

[thorn isle]

there should be a method on the World class for it

myeah, assertions do have their drawbacks

[thorn isle]

the rtp positions are stored in a ring buffer ahead of time, so when a player requests to teleport, i can just pop one from the buffer and teleport them instantly, and then queue a new position to be found and added into the buffer asynchronously

this means i can be quite strict with my position validation without having to worry about players running into shit like "sorry, couldn't find a position to teleport to in time" like many other rtp plugins do

[quaint basin]

I have no idea how to do this

[thorn isle]

i think World::getBiome does it, i'm not 100%

[wet breach]

seems you missed one. Threads die when they complete which is the normal way they should die. Hence a while loop keeping a thread alive as the the while loop condition is never met but when it is, it will die 🙂

[thorn isle]

some of the biome methods return biomes computed from the noise, others from actual chunk data, and i don't know if it's even documented which does which

[thorn isle]

yes, it seems like i overlooked the obvious 🤡

[quaint basin]

/**

// Paper end

I don't know which one I should use.

[thorn isle]

honestly me either

This is computed by looking at the noise biome at this and surrounding quarts
this makes me think this is what you should use

The computed Biome is the Biome as seen by clients
this makes me think this isn't what you should use

[ivory sleet]

@quaint basin what version ru using?

[quaint basin]

1.21.8

[ivory sleet]

Ah ok

[quaint basin]

That's the same method lol

But you thought exactly what I thought

[thorn isle]

yeah that's why i'm conflicted

it says one thing and then another

i think what it means to say is it does read the biome from the chunk data, rather than noise, but uses the same interpolation as the client uses to determine where the possible biome borders between the quarts are

[quaint basin]

gpt explained it to me and maybe he's right xd

He seemed convincing to me

[thorn isle]

try World::getVanillaBiomeProvider

note that this approach doesn't work if you're using a world generator or a plugin that changes where biomes are after the world is generated

[quaint basin]

https://imgur.com/a/7R2B66B idk if this is right

[thorn isle]

e.g. it won't work on most earth maps where the biome is part of the map data

[quaint basin]

But it seems so xd

[thorn isle]

i think it's confusing between the two different meanings of noise here

there is noise that's used in world generation, and then there's noise used by the client to draw the biome borders after world generation

since the biome storage resolution in chunks is 4x4x4, using that data directly would make ugly straight lines

so what the client does is it adds some noise to that data so the borders twist and turn a bit at random

[quaint basin]

The computed version uses client-side noise. I thought this would be a problem if the client could manipulate the data to say that the biome at certain coordinates was BIOME X, while on the server it was Y, but that's impossible

[thorn isle]

either way, this should be 100% noise based and not need a chunk

[quaint basin]

i dont have this method

[thorn isle]

https://jd.papermc.io/paper/1.21.9/org/bukkit/generator/WorldInfo.html#vanillaBiomeProvider()

should exist on 1.21.8 as well

it's just on the WorldInfo interface which World extends

[eternal oxide]

Does not exist on Spigot

[quaint basin]

oh u said get

[thorn isle]

judging by the docs/sources he's looking at, he's on paper

[quaint basin]

yea im on paper

[thorn isle]

oh i maybe made a typo

[quaint basin]

now it is provider#getBiome?

[thorn isle]

also check the regular biomeProvider() and see if it's null i guess

myeah

[quaint basin]

eturn the Biome which should be present at the provided location.
Notes:
This method must be completely thread safe and able to handle multiple concurrent callers.
This method should only return biomes which are present in the list returned by getBiomes(WorldInfo)
This method should never return Biome.CUSTOM.
Params:
worldInfo – The world info of the world the biome will be used for
x – The X-coordinate from world origin
y – The Y-coordinate from world origin
z – The Z-coordinate from world origin
Returns:
Biome for the given location

why must lol

[quaint basin]

it is @nonnull

@NotNull BiomeProvider vanillaBiomeProvider();

[thorn isle]

i mean the regular biomeProvider()

world generators can set their own biome provider, which that will return if set

if not set, world gen falls back to the vanilla provider, which is always present

so we should do the same; prioritize the one set by the custom generator, or if not set, use the vanilla one

[thorn isle]

because of callers like us who're using it asynchronously

i.e. we require it to be thread safe

[quaint basin]

Yes, but for me, saying "must" means that it might not be thread-safe, but in principle it is thread safe

[thorn isle]

the notes are for the devs implementing the interface

telling them that they must make it thread safe

[quaint basin]

oh ok

[thorn isle]

because devs like us expect it to be thread safe

[quaint basin]

make sense now

[quaint basin]

You say to use the regular getProvider. If it's null, then should I use the vanillaProvider?

[eternal oxide]

is teh getProvider marked as not null?

prfetty sure its never null

nope you are correct, it can be null

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#getBiomeProvider()

[quaint basin]

How can I obtain WorldInfo through World?

[thorn isle]

World extends WorldInfo

if you have a world, it is your worldinfo

wouldn't be accurate, but generally it shouldn't lol

Is there's another way to compile it without BuildTools? I have 1.6.4 compiled minecraft_server POM's by my friend, but he forgot how he did it
Now I need to make 1.3.2 minecraft_server POMs

[buoyant viper]

ModCoderPack also exists for some older versions if u need to decompile or modify the client and/or server, but its mappings werent the greatest sometimes

idk about workin on anything earlier than 1.7 tbh

[thorn isle]

for the record pom is the build metadata file that maven uses to configure a project build, and isn't related to this

[buoyant viper]

if u just need an older (pre 1.8) server jar u could try scouring the umbral plane

or @wet breach probably has every build known to man

    // Calculate the direction from the shooter to the entity
    Vector direction = hitEntity.getLocation().toVector()
            .subtract(shooter.getLocation().toVector())
            .normalize()
            .multiply(20); // Adjust for strength

    // Apply the knockback
    hitEntity.setVelocity(direction);
}

[young knoll]

Probably too strong

The server doesn’t like players moving too quickly

[fading drift]

idk why this cant find it, but my other project can find it when I specify a library

I havent touched this in over a year, is there something I'm forgetting?

[young knoll]

spigot-api is just the api

If you want the server internals too just use spigot (and run buildtools for that version)

[fading drift]

I forgot what buildtools is

is there a guide somewhere

[young knoll]

?bt

[undone axle]

https://www.spigotmc.org/wiki/buildtools/

[fading drift]

so am I correct in saying that to use server internals in code, I must provide a spigot jar

[abstract fox]

Hi, I'm having a problem with my Minecraft server. Sometimes I can't move my inventory. If anyone knows why this is happening, please let me know. I'd really appreciate it.

[young knoll]

Buildtools will install it into your maven local

[fading drift]

yeah sorry I just figured that out

so if I wanted to collaborate with others, they would either need to run buildtools themselves or I would supply the jar

[sly topaz]

they would run buildtools themselves

supplying the jar sounds annoying given they'd have to put it at the right place

[fading drift]

not if I just have it in the git repo and use <dependency> <groupId>org.spigotmc</groupId> <artifactId>spigot-server</artifactId> <version>1.8.8-SNAPSHOT</version> <scope>system</scope> <systemPath>${basedir}/../../libs/spigot-1.8.8.jar</systemPath> </dependency>

[eternal oxide]

you need the non snapshot repository for the api, don't use system paths

Hi guys.

I am making a prison core for my server and wanted to ask smth related to the libs that amma start.

Text color utils
Config file loader
Command manager
Item builder
Simple GUI builder
Cooldown manager
Small event utilities
Database service (MySQL, Mongo)
Economy wrappers
Cache utilities
Json adapters
File utilities```

What else should I add in the Libs, never made Libs so idk what to add XD

Also the prison core is gona be like OPLegends/EMC etc

[wet breach]

you should limit the amount of libs

if you are making a core plugin, that core plugin should be primarily the lib to rely on to provide stuff. Therefore, the core itself you should limit the amount of outside libs it itself. Otherwise your core is at the wim of these libs or you are waiting on these libs to provides updates/fixes or when they do it throws everything you have out of whack. So, you really should limit to what you really need.

If all you are doing with these libs is just making use of a single feature or just a few methods, it would be wise then to just create your own feature/methods into the core of the plugin yourself. This also removes the amount of excess code your core ends up having or unnecessary stuff in general.

@azure escarp

[quaint basin]

If I do item = world.dropItemNaturally; Map.put(viewerUuid, item.getEntityId), can I intercept the SpawnEntityPacket and then, if the player's UUID from that packet is on that map and the entity ID of that packet is the value with the key of the player's UUID on the map, will cancel sending the packet to the client work? My fear is that the packet will be sent before Map.put.

[chrome beacon]

if it runs before or after depends entierly on where you call map.put

[thorn isle]

i dislike "core" plugins

and libraries

they tend to become an endless dumping ground for difficult-to-maintain garbage that then ends up dragging everything else down

if i had a cent for every plugin that'd died and was abandoned because the core it relied on became unmaintainable, i wouldn't be a millionaire, but i would have many cents

[quaint basin]

I use map.put after the dropItemNaturally call

[quaint basin]

There was a missing semicolon (;) before Map.put

[thorn isle]

a way to get around this is to modify the map before adding the entity to the world

you can use the World::spawn method with Item.class, then in the Consumer<Item> which runs before the entity is added to the world, apply a random drop velocity to the item (this is all the dropItemNaturally method does), and put it into the map

i think it's at least in principle possible for the packet to get sent before the main thread gets to the map.put, but i don't remember if i've had that happen in practice

for reference, here is the actual impl of dropnaturally

    public Item dropItemNaturally(Location loc, ItemStack item, Consumer<? super Item> function) {
        Preconditions.checkArgument(loc != null, "Location cannot be null");
        Preconditions.checkArgument(item != null, "ItemStack cannot be null");
        double xs = Mth.nextDouble(this.world.random, -0.25, 0.25);
        double ys = Mth.nextDouble(this.world.random, -0.25, 0.25) - (double)EntityType.ITEM.getHeight() / 2.0;
        double zs = Mth.nextDouble(this.world.random, -0.25, 0.25);
        loc = loc.clone().add(xs, ys, zs);
        return this.dropItem(loc, item, function);
    }

however, it turns out that it has a consumer that's run before the entity is added to the world as well, so you can just call this instead of world::spawn

[quaint basin]

Yes, thank you

[minor garnet]

nmsPlayer.playerConnection.sendPacket(new PacketPlayOutCamera(cam));

im trying to make it so that when the player enters the view of an entity (like when spectating it), the entity keeps rotating its camera based on the
player's camera movement. However, iim not finding a way to detect the player's yaw and pitch while spectating. PacketPlayInFlying does not contain any yaw or pitch values. Is there any way to detect the player's camera rotation (yaw and pitch) in this situation?

[thorn isle]

i'm not certain if the client even sends any "look around" input in that state, since the client can't look around while spectating

you can get keypresses with the input event/packet, but i'm not sure about mouse input

[chrome beacon]

It doesn't but there's a bit of a trick to get it do so anyway

If you make the player ride on the entity it's currently spectating it should start sending movement packets

[minor garnet]

you can get keypresses with the input event/packet, but i'm not sure about mouse input

yeah i can do that

[thorn isle]

mmm i remember this trick

[minor garnet]

thats true

but camera rotation ?

[thorn isle]

i don't recall it being used to capture mouse input, but it could work if it actually sends proper movement packets

i'm just not sure if the player would just send the spectated entity's pitch/yaw or its deltas, since the screen is locked to those

worth a try at least; i do vaguely recall someone doing something like this before, so it might be possible

[chrome beacon]

^ I'd give it a try

Do let us know if works

[minor garnet]

sre

[quaint basin]

how can i get a chunk spanshot

[thorn isle]

Chunk::getSnapshot

do use the javadocs though

[quaint basin]

no exists

oh nvm

But what should I use this for?

[thorn isle]

it's an immutable and thread-safe snapshot of the chunk's state

use it to find a valid position to place the player in within that chunk

[quaint basin]

What if a player places a block?

between the time I receive the snapshot and the tp

[thorn isle]

this way you're not bogging down the main thread with your checks

that is highly improbable; but i suppose if you really want to avoid that, load the chunk before the tp and verify that the space isn't occupied, and pop another location from the buffer if it is

[young knoll]

The overhead of taking a chunk snapshot probably isn’t worth saving the overhead of getting the highest block at a location

[thorn isle]

if your checks are very simple, like just finding the topmost block in a column using the heightmaps, and making sure the block is safe to teleport on, you can forgo the chunk snapshot

i do relatively complex checks, so rather than loading another chunk if the checks fail, i go through multiple positions within the chunk asynchronously

[quaint basin]

what checks

[thorn isle]

that the position is valid

[quaint basin]

like what

[thorn isle]

you don't want to teleport the player into a lava lake or at the bottom of a ravine

i also avoid placing the player on top of trees, searching underneath foliage instead

[quaint basin]

The tallest block in the world will never be under a cave

[thorn isle]

cave != ravine

[quaint basin]

Yeah, I need that too

[quaint basin]

Oh, right.

i need that too

xd

[thorn isle]

the upside of taking a snapshot is that you are much more likely to find a valid position somewhere in the chunk and won't have to load another chunk

[quaint basin]

Is your code public?

[young knoll]

Shoutout to the MOTION_BLOCKING_NO_LEAVES heightmap

[thorn isle]

no

[quaint basin]

what is it

[young knoll]

Sadly you could get unlucky and end up picking the column with the tree trunk in it

[thorn isle]

records the highest position with a block in a block column, ignoring leaves

[young knoll]

A block that has collision

[quaint basin]

no idea how can i use MOTION_BLOCKING_NO_LEAVES

[thorn isle]

chunk snapshot has getHighesBlock(Heightmap) or something

so does chunk

world maybe too

[quaint basin]

and can i do that async

[thorn isle]

on the snapshot, yes

on anything else, no

hence taking the snapshot

[quaint basin]

the problem with this is a player placing a block meanwhile

[young knoll]

I think you technically can read the world async

[thorn isle]

you can, and it's actually quite safe and performant on paper

[quaint basin]

wdym buffer

[thorn isle]

on spigot i think it will just schedule a task that wraps the get to run at the start of the next tick, so you'll impose a latency up to 50ms

[quaint basin]

why chunksnapshot then

[young knoll]

Well if it does schedule a runnable a chunk snapshot will allow you to do everything in the same tick

Instead of check -> wait -> check again -> wait -> etc

[quaint basin]

it does not have

[thorn isle]

just use the javadocs

all the methods are there

open the chunksnapshot page and ctrl-f height or something, or just read the methods

i'm not a search engine

[quaint basin]

I still don't understand, but okay

[quaint basin]

I thought you already knew these methods

[quaint basin]

i alr read evertyhing about chunksnapshot

[thorn isle]

i do, and i know it's there

[quaint basin]

and doesnt have anythin about heightmap

[thorn isle]

but i'm not 100% about the name

[young knoll]

Yeah wtf vcs2 you don’t know every spigot method signature off the top of your head?

[quaint basin]

You don't know about player.sendMessage?

[thorn isle]

despair

okay upon further inspection of the javadocs, it seems like the chunksnapshot is actually ass and forces you to use a specific heightmap type

[quaint basin]

What if all positions are unsafe in the buffer?

[thorn isle]

the data for all the heightmaps is recorded on it, but there's only api for querying the "highest taken" one

[thorn isle]

shouldn't happen; have a big enough buffer

in the off chance that they are, you can tell the player to try again later

[quaint basin]

For me, the buffer would be a maximum of 16*16 locations

[thorn isle]

you'd need like 300 players to use the command within a few seconds to run it dry

[quaint basin]

I'm not understanding anything 😭

[thorn isle]

put a reasonable cooldown on using the command and it shouldn't be a problem

[quaint basin]

Does the buffer represent safe locations for only one chunk?

[thorn isle]

serverwide

or no, worldwide; or whatever other domain you want, but worldwide makes the most sense

every position in the buffer should be interchangeable

[quaint basin]

But my range is 50000x50000

[thorn isle]

so if you want to rtp in the nether, you pop a position from the nether world's buffer

[quaint basin]

I'm not going to have a buffer of enormous size

[thorn isle]

it can be 30 million by 30 million, it doesn't matter

[quaint basin]

A list of 30 million size?

[thorn isle]

no

the buffer is a list of pre-calculated safe rtp destinations

it's called a buffer because it bufers the output of the producer thread (finding the safe positions) and the consumer thread (teleporting players to them on demand)

it allows you to dispatch teleportations instantly rather than have players wait until you find a position for them

[quaint basin]

And the list of safe positions will be at most 16x16 in size, which is the area of ​​a chunk at a randomly chosen location?

[thorn isle]

and once you do, you pop it from the buffer and tell the producer to find a new safe destination to put in the buffer

no

it can be any size you want, depending on how many rtp positions you think you'll need to "burst" through

[young knoll]

Make it dynamic :p

[thorn isle]

e.g. if you have 100 concurrent players and you expect they might all decide to run /rtp at the same time, your buffer should be 100 positions long

[young knoll]

If it ever gets down to 0 increase the capacity by 10 or something

[quaint basin]

When is the buffer created?

[thorn isle]

at startup, and then topped up as needed

in principle you could persist it so you don't need to recompute it at startup, but in practice that's not worth the effort

[quaint basin]

And when should I reallocate the buffer?

[thorn isle]

this isn't c, you don't have to reallocate it manually if you have to resize it

or are you intending to ask when you should refill it?

[quaint basin]

Either I'm stupid or you're explaining things badly because I don't understand anything

[young knoll]

You hold a list of valid teleport locations

If its size is < howManyYouWantToHaveBuffered then you calculate a new one

[quaint basin]

From what I understand, you're telling me to have a list of safe locations in the startup, but these safe locations will eventually run out, so I'll have to add more safe locations but I don't know when, and to my liking, this is just complicating the basics because I don't understand anything

[quaint basin]

when

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA

[thorn isle]

despair

you hold the list forever

when you use a location, you remove it from the list

when the list becomes too small, you add new ones to the list

[quaint basin]

wtf

[thorn isle]

okay

conceptualize this

you have a fridge

yes?

[quaint basin]

yes

[thorn isle]

the fridge has food in it

[quaint basin]

no

[thorn isle]

what happens when you get hungry?

you take something out of the fridge and eat it

[quaint basin]

I'm going to have dinner soon

[thorn isle]

now the fridge has less food in it, yes?

[quaint basin]

yes

[thorn isle]

so at some point you look at the fridge and go "hm, i don't have much food left"

and at that point you go to the grocery store to get more food

and you put it in the fridge

the fridge is your buffer

the food is teleport locations

[quaint basin]

Are you suggesting creating a list of safe locations in onEnable?

[thorn isle]

the grocery store is the position finding algorithm

yes, that's what "at startup" means

[young knoll]

You create it at startup

[thorn isle]

and as the list over time shrinks, you add more positions in it so you don't run out

[young knoll]

You fill it over time, as needed

[quaint basin]

Having this list doesn't make sense because 10 seconds later all those locations on that list could be unsafe locations

[young knoll]

You could actually have the producer be its entire own thread as long as you use a thread safe list and make use of BukkitSchedular#callSyncMethod to get your chunk snapshot

[quaint basin]

This is unlikely, but I want to avoid it, but I think you're complicating things

[thorn isle]

this is what i do, i have a BlockingArrayQueue and a thread blocking on add on it; it'll run whenever there's space

[young knoll]

Well if you want to do it the way extreme lazy way

Just teleport the player way above the surface and give them slow falling for a bit

That pretty much means you only need to check you aren’t teleporting them into an ocean

[thorn isle]

if this is your first plugin and the concept of a buffer is difficult for you, you can just do the lazy thing and tell the player "you will be teleported soon" when they run the command

and find the destination in real time, and teleport as soon as you find it

[quaint basin]

Why would I be slow-moving, wtf?

[quaint basin]

Do you want to see the latest plugin I made?

[thorn isle]

okay now you are just clowning on him

[young knoll]

Slow falling

So they don’t take fall damage and can steer themselves away from lava or ravines or whatever

[quaint basin]

https://hastebin.com/share/exofoxelos.typescript

Based on this code, do you think this is my first plugin?

[thorn isle]

brother i have been trying to explain to you what a buffer is for the past half an hour

[quaint basin]

I know what a buffer is; you're the one who doesn't understand my question

There's clearly a simpler way to do this than what you're talking about

[young knoll]

This is the simple way

And unless you have a really bad algorithm for finding a safe location or the player is really unlucky

It won’t take that long

[quaint basin]

Wouldn't it be easier to generate a random location when the player types /rtp and check if the chunk contains a safe location, and if it doesn't (16*16 attempts) tell the player to try again?

[young knoll]

Sure

[quaint basin]

I didn't understand why a buffer would be advantageous here

[young knoll]

Means you can teleport them instantly

And never have the command fail

[quaint basin]

If there are no safe locations in the buffer, you will not be teleported instantly

[young knoll]

There should always be safe locations in the buffer

If there aren’t, you need a bigger buffer

[quaint basin]

There might be a moment when the buffer is empty and the person types /rtp - so they are not teleported instantly

[young knoll]

Like I said, the buffer should never get empty

If it does that means you should make it bigger

[quaint basin]

So I'm going to be checking the buffer every tick?

[young knoll]

You could, or you can do as vcs2 said

[mortal hare]

https://www.youtube.com/watch?v=QT13kk8HDDo

[wet breach]

you can have an external program doing this just fyi

to blow your mind that not everything has to run in the server

[sly topaz]

unless your world is pregenerated and you only teleport to generated areas, that wouldn't be possible

[buoyant viper]

IPC go brrr

[wet breach]

yeah, be quite dumb if you don't have a pre-generated world. Lag galore otherwise

[sly topaz]

I mean, you can only pre-generate so much and random teleport makes it easy to go out of that bound in order to avoid teleporting players too close to eachother

[wet breach]

you can pre-generate the entire map?

[sly topaz]

is this for a minigame? If that's the case then yeah

[wet breach]

what is stopping generating a survival world?

not understanding here

[sly topaz]

compute lol

[wet breach]

compute?

[sly topaz]

pregenerating a world can take weeks if the range is big enough

[wet breach]

no

only takes hours

unless you have a potatoe

[sly topaz]

it definitely does not, and besides file size is a concern too

[wet breach]

why is that a concern?

we have terrabyte drives.....which MC is not going to fill up

10milx10mil generated world without doing anything takes up like 10GB and it takes something like 3-4 hours to generate

[sly topaz]

takes about 17gb if no nether and end, and probably more like 12 hours

[wet breach]

not sure what you are using that it takes so long for you o.O

[sly topaz]

you can check size with chunky's calculator, it scales pretty badly: https://onlinemo.de/world

[wet breach]

what do you mean scales pretty badly? Every region file is going to be relatively the same size

if we are not factoring in any modifications being done

[sly topaz]

just take a look at the calculator as you increase the radius, it is pretty insane

and you can check pretty much any chunky guide about how much time it takes, they warn people about it possibly taking a day if not multiple days

[wet breach]

50k blocks is not 500gb

[sly topaz]

it is radius

would be 50x50k

[wet breach]

yeah obviously wrong

[sly topaz]

it isn't though

[wet breach]

but it is because most of your world is air blocks

sorry, there is not 500gb worth of data in 50k by 50k

[sly topaz]

you can pregenerate a world with chunky and see for yourself

we are not in 1.8 anymore where the worlds wouldn't go past 100gb

[wet breach]

even setting it to 1.8 that site says there is 200gb+ in 50k by 50k

so yeah, not trusting it. Obviously whatever math it is using is very flawed

[sly topaz]

your perception of how big worlds usually are is just wrong

[wet breach]

its not. ran servers before. In terms of amount of storage space minecraft worlds are small

[sly topaz]

most servers won't pregenerate past 10-20k radius, since that's plenty for a survival for a few years

[wet breach]

I have always done 10mil by 10mil

[sly topaz]

yes, and that would be around 10gb

it just scales really badly

[wet breach]

I said this

there is no way that if 10mil by 10 mil is 10gb, that 50k by 50k would be significantly larger

[sly topaz]

actually 16gb if it is 10x10, you were probably doing 5x5 actually

[wet breach]

no

[sly topaz]

again, if you don't believe it then go pregenerate a world, see how much it takes and what size you end up with

[wet breach]

it averaged out to 10gb. IT could be larger now, but there is no way from 1.8 to 1.21 that the same dimensions would be an order of magnitude of 50 times larger in space

when ever I feel like setting up a server I will. on pc that size will take a while, but on a server box it takes only a few hours

[sly topaz]

10x10, probably about 12 hours using spigot, that's at least how much it took me last time I did it (in 1.21.5)

[wet breach]

10x10? as in 10k or 10mil?

[sly topaz]

10k radius

wait, you were talking about millions? Lol

because radius in the millons take weeks

[wet breach]

radius in the millions is not slower then a cube

cube is larger then a circle =/

[strong forge]

you obviously haven't ever generated a world before lol

that site provides a very accurate estimate for world size, it's been sampled over hundreds of worlds from the guy that created it

it's kind of ignorant to just write it off as "the math must be wrong" when you can literally just test it once and see immediately that it's correct

[silent river]

Just from a mathematical standpoint: Disregarding the Y-axis, radius means that from an origin, assuming a square, it extends out by radius blocks in each direction. So 10 blocks radius results in a 20x20 square. Adding together those results in 400.

Let's do the same for 10k (5k rad): 10,000 * 10,000 = 100,000,000.
Again for 20k (10k rad): 20,000 * 20,000 = 400,000,000.

As you can see, a 2x increase in radius results in a 4x increase in the amount of blocks that need to be generated (this is the same case in chunks btw; you'd simply divide the radius by 16 and the result by 256). This means shit scales fast.

Let's do the same calculation for 10 million:
10,000,000 * 10,000,000 = 100,000,000,000,000

That's a ton of blocks, don't you think? And you suggest that you can put 100 trillion columns of blocks in just 10 gigabytes of data? You must be insane.

[solid cargo]

Yep, same thing is 3d printing actually. When you increase your model size by 10%, the time to print doesnt increase by 10%, instead its closer to 30% ish

[silent river]

Well, it increases by 10% cubed, which is about 33.1%

[solid cargo]

Yes, thus ish

Anyways the point stands, the increase is not linear

[ivory sleet]

ignoring time complexity, how did u get 10^7 x 10^7 to fit in like 10^10 bytes?

ig u get 10^2 also if ud consider height

so 10^16 blocks in 10^10 bytes

[smoky anchor]

compression babyyy

[ivory sleet]

and all that in 4h

[wet breach]

most of the world in minecraft is air

air blocks don't take up space like you think it does

[smoky anchor]

That sounds wrong
MC does have some optimizations for single block sub-chunks, is that what you mean ?

[silent river]

And in average about 80 blocks per column is not air

What's your point

Actually more than 80, it extends in the negative Y as well

[smoky anchor]

was it full or subchunks that have this
I don't remember exactly

[wet breach]

air blocks don't take up space

[strong forge]

generate a world and then come back

[wet breach]

I have over the years.....I am not going to generate one now on my pc as it does take longer on a pc then it does on a server box

[strong forge]

then stop spreading misinformation

[wet breach]

you guys act like I am new to MC or something

[silent river]

real

you seem to be

[strong forge]

you sound like it with how you understand world gen lol

[smoky anchor]

How can air "not take up space"
It is the same as a normal block in a block-mixed chunk
there has to be some "x of air blocks" information
I'll just pull up the chunk spec

[strong forge]

air compresses rather well but it doesn't take up "zero space"

[silent river]

And chunks also don't consist purely of air lol

[wet breach]

air blocks take up no space, you can go look to see how blocks are stored

[silent river]

They have a rather big amount of non-air blocks too

[silent river]

You go look up how blocks are stored

Please

[strong forge]

yeah i know how they're stored because I've written tools for this lol

[wet breach]

I have? I am quite familiar with the anvil storage spec

[silent river]

You pretty clearly aren't

[wet breach]

alright, show me where air is taking up space?

[strong forge]

either way just to stop derailing the original topic, the onlinemo.de site is very accurate for world sizes, and that is accounting for the air blocks

go generate a real world and you can easily confirm it's correct

no need to argue over nothing here lol

[smoky anchor]

I have started generating a world with Chunky
10k x 10k
20% there, will take like 4 more hours
So far at 3GB I think

[wet breach]

what are the 0's? never used chunky

[smoky anchor]

x y for center to generate around

[wet breach]

ah

[strong forge]

technically 20k x 20k then but that should be about 16-17gb according to onlinemo.de

[smoky anchor]

ye 10k radius

[strong forge]

sounds about right from your 20%

[wet breach]

hmmm....seems I am going to have to manually update WorldBorder

[tacit thistle]

You can just calculate how many chunks would be in 10mil*10mil and, as you are quite familiar with the anvil format, use one sector per generated chunk as a lower bound

[smoky anchor]

Ended the little experiment to stop torturing my PC
31% and I have 4.5GB world

[quaint basin]

Yes, and the result = enormous processing load just so the player doesn't have to wait 10 miliseconds to teleport.

Soon you'll be telling me to have a process to set the player's life, kill the player, kick them out, etc.

1001 processes 😎

[wet breach]

no on that last part, and not sure where you get enormous processing load from as well

anyways, it really depends on what exactly you want it to do

the reason an external process would be faster other then most likely being on a different core from the server is that its just a smaller program overall therefore its loop cycle is a lot faster then that of the servers. So even if it did have to process a lot, it would still be a faster cycle

[young knoll]

I mean

You’d still need the server to generate the chunks

Assuming everything isn’t pregenerated

[wet breach]

right, if its not pregenerated

[thorn isle]

The other advantage of a buffer is that you avoid spikes in cpu load by being able to distribute the workload over time

100 players running /rtp at once will make the server shit bricks if it's already under load

With a buffer, it just means a lightweight background process is going to run for some amount of time until the buffer is refilled

The compute used is the same, but it's spread out

[ivory sleet]

Tbh dating back to the original problem, you can also just rate limit rtp on an individual (w a cooldown) and a collective level (not allowing more than x rtp requests per tick), more so if u dont want to buffer, there's probably no harm in letting the player at hand wait a little bit whilst the server is fetching a safe location?

[onyx fjord]

does Bukkit#getPlayer(name) just ignore case or something else ?

[wet breach]

pretty sure it ignores case

[worldly ingot]

It actually does matching if I'm not mistaken

Like if I were to do Bukkit.getPlayer("2008") it would return my player despite the username being "2008Choco". It searches for names that start with the input string and returns the one that's closest

Bukkit#getPlayerExact() doesn't do matching and requires an exact match username. #getPlayer() checks for exact matches first

[young knoll]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/CraftServer.java#595

[hybrid spoke]

so it's case insensitive, but it may not return the player wanted if you're not precise enough

[worldly ingot]

Correct

[worldly ingot]

My summary here is accurate

[wet breach]

well, I was partially right then lol

Yay for choco with knowing the exact thing

[umbral ridge]

hey

this is the new locator bar, is it possible to create these points? in the code?

[smoky anchor]

iirc an entity has to be present
you give it the waypoint something attribute and it shows
I don't remember how but you can retexture the points with custom RP

[thorn isle]

i don't recall there being api to directly create them (though the protocol does support that, even without an attached entity), but you can use the attribute api to make entities have them

basically the protocol just sends some (uuid, x,y,z, icon id) packet for each

[umbral ridge]

oh so the point is an entity like an npc

alright. btw is locator bar always visible? because its invisible right now, in an empty world. my guess is that it only appears if a point or more is/are present?

[smoky anchor]

I believe only when a point is in the fov of the thing

otherwise it switches back to XP

it also switches to XP when the XP changes

[thorn isle]

rather than fov i think it's tied to range

though i'm not 100%

[umbral ridge]

complicated stuff

its complicated to spawn it and then you have to do all kinds of stuff which would probably take me a few hours to figure it out and polish... not worth it

you have to have an entity, then that entity has to have an uuid, then if its an entity, you can attact an attribute to it, but thats just a mess with command blocks.. meh

and on top of that, that only works for singleplayer world. not local server kind of thing

[smoky anchor]

"then that entity has to have an uuid"
I find this very funny, every entity has a uuid whether you like it or not lol

[thorn isle]

i don't get why there's no proper api for it

the protocol supports just sending waypoints directly to the client, no entities involved

there should just be a Player::addWaypoint(UUID, Location, Icon) or something

[sullen marlin]

Maybe you could PR it

[pseudo hazel]

spigot is clearly understaffed

xD

[golden turret]

how do i create a player head based on the texture url?

nvm, found it

                PlayerProfile profile = Bukkit.createProfile(UUID.nameUUIDFromBytes(url.getBytes()));
                PlayerTextures textures = profile.getTextures();
                textures.setSkin(URI.create(url).toURL());
                profile.setTextures(textures);
                meta.setPlayerProfile(profile);

Hello is there a way to get the string of a chat message that was created by console via command?
data get entity @e[type=minecraft:zombie,limit=1]
Outputs a string a chat that I want. I tried all of the chat events, none captured it.

[young knoll]

You’d have to use some sort of system to intercept logging

But this seems like

?xy

[undone axle]

https://xyproblem.info/

[noble saddle]

yes it is lol

Im trying to get nbt of an entity

but I want to avoid using the NBT API

[young knoll]

What NBT do you want

[noble saddle]

Theres a way to intercept logging with bukkit? Like through an event?

[young knoll]

Pretty much all of it should be available through api methods

[noble saddle]

literally an entity's entire NBT

huh ok

[young knoll]

getHealth for health, getEquipment for armor and held items, etc

[noble saddle]

oh right, I was doing that at first which was fine, but the shear amount .... it was getting too much

I just thought its gonna be faster if I can somehow obtain the NBT

[young knoll]

What do you want to do with it

[noble saddle]

duplicate an entity. copy its exact current state at a specific tick and duplicate it at a later point.

[young knoll]

Version?

[noble saddle]

latest

[young knoll]

Entity#copy(location)

Or Entity#createSnapshot

wow it worked thanks!

[native gale]

Does anyone have a clue how to correctly encode or decode this field? The protocol description on the wiki is a bit confusing. I've been lurking on GitHub since yesterday looking for an example, because surely I'm not the first person on the planet who has attempted that, but I didn't find anything particularly useful. My goal is to reach and modify paletted containers in the chunk sections

[sullen marlin]

Presumably it's just a varint plus bytes?

What does the link say

[native gale]

https://minecraft.wiki/w/Java_Edition_protocol/Chunk_format#Data_structure

[thorn isle]

best to check the chunk packet data encoding/decoding methods and just do what those do if you can't make sense of the wiki description

off the top of my head, all that field is is a list of serialized chunk sections

which themselves are just serialized palettedcontainers

if you have access to nms, you can delegate encoding/decoding directly to nms code

otherwise you'll have to put a decent bit of shoulder grease into it, since there are several different types of palette strategies, registries are involved, and you have the whole "block nibbles in longs" logic from the container itself to deal with

       int chunkSectionIndex = 0;
        LevelChunkSection[] var4 = chunk.getSections();
        int var5 = var4.length;

        for(int var6 = 0; var6 < var5; ++var6) {
            LevelChunkSection levelChunkSection = var4[var6];
            levelChunkSection.write(buffer, chunkPacketInfo, chunkSectionIndex);
            ++chunkSectionIndex;
        }

buffer here being a FriendlyByteBuf where the data goes

ignore chunkPacketInfo and i think also chunkSectionIndex, those are paper antixray nonsense

LevelChunkSection::write is very simple as well

    public void write(FriendlyByteBuf buffer, ChunkPacketInfo<BlockState> chunkPacketInfo, int chunkSectionIndex) {
        buffer.writeShort(this.nonEmptyBlockCount);
        this.states.write(buffer, chunkPacketInfo, chunkSectionIndex);
        this.biomes.write(buffer, (ChunkPacketInfo)null, chunkSectionIndex);
    }

states and biomes both being PalettedContainers, for BlockState and Biome respectively

palettedcontainer write directly delegates to PalettedContainer.Data::write

        public void write(FriendlyByteBuf buffer, @javax.annotation.Nullable ChunkPacketInfo<T> chunkPacketInfo, int chunkSectionIndex) {
            buffer.writeByte(this.storage.getBits());
            this.palette.write(buffer);
            if (chunkPacketInfo != null) {
                chunkPacketInfo.setBits(chunkSectionIndex, this.configuration.bits());
                chunkPacketInfo.setPalette(chunkSectionIndex, this.palette);
                chunkPacketInfo.setIndex(chunkSectionIndex, buffer.writerIndex());
            }

            buffer.writeFixedSizeLongArray(this.storage.getRaw());
        }

again ignore chunkpacketinfo, that's antixray nonsense

what this does is write first the palette and then the raw long[] of the data itself into the buffer

this is the part where it gets kind of nasty, because there are 4 implementations of palette

i'd really recommend some library or just straight up using nms instead of rawdogging it if you have to go this deep into it

[young knoll]

Just be lazy and always use the fancy palette

Can someone help me with the protection stones pre 1.13 plugin?
I want it to:

• prevent the actionbar error from appearing
• remove protection from inventory when placed in creative mode

DM for more info

[native gale]

Yeah, I tried the NMS path, and it would be pretty straightforward if I knew how to create an instance of net.minecraft.world.level.chunk.LevelChunkSection. If I were able to do that, I would just feed the buffer into its read method and call it a day

Sadly, .read() is not a static method. I need an already existing instance of LevelChunkSection to decode the buffer, and I can't figure out where to get the parameters needed for its constructor

[thorn isle]

public LevelChunkSection(Registry<Biome> biomeRegistry, Level level, ChunkPos chunkPos, int chunkSectionY)

i assume you're having trouble finding the biome registry?

[native gale]

Yes, as well as Level

[thorn isle]

level is just the handle of a bukkit world

((CraftWorld)world).getHandle()

it'll be a ServerLevel in particular

for the registry, uh

i never remember where their repository is, let me see

it used to be in BuiltInRegistries but ever since they became network synchronized they were moved into some dynamic registry nonsense

you have to use the ResourceKey<Biome> from nms.Registries to retrieve the registry from somewhere

possibly the registry registry

[native gale]

Uh...

[thorn isle]

alternatively

this is a bit of a hack, but you can get an existing chunk in the world of interest, and just get the biome registry it references

it's a public field on ChunkAccess which is the supertype of e.g. LevelChunk, which is the "handle" of bukkit Chunk

[native gale]

I wondered about it, by the way. Wouldn't it be very slow for this kind of packet? I know it might be an obviously naive question, but I genuinely have no idea about the internal kitchen here. It's my first time messing around with the protocol

[native gale]

By the way, I tried to listen for ClientboundRegistryDataPacket to get the registry, and indeed it sends something with the resource key ResourceKey[minecraft:root / minecraft:worldgen/biome], but I was kind of stuck there, because I didn't know how to convert it to Registry<Biome>, so I dropped this idea

[thorn isle]

you only need to get it once per world per session

[native gale]

Huh... Good point

[thorn isle]

ResourceKey[minecraft:root / minecraft:worldgen/biome]
this is the ResourceKey<Biome> in nms Registries

Registries.BIOME specifically

it's a key into the registry registry

i assume you can get the biome registry itself using the key with BuiltinRegistries.REGISTRY.get(Registries.BIOME) or something along those lines, but with the generics involved it's difficult to say for sure without trying it out

choco or md or others probably know better, but if they don't spontaneously manifest with an answer, going with the hack of grabbing it from a chunk should work as well

[native gale]

Yes, I guessed that. It also sends a bunch of entries along the key, but I was kind of lost about what to do with them. I had the hypothesis that since they are sent over the web, and the client needs to decode them somehow, there must be a method to convert those back to Registry<Biome> somewhere, but I gave up looking for it, it's too difficult

[native gale]

So yes, I'll probably try this hack. Thanks

[thorn isle]

those are the palette of the paletted container

basically the way the container works is that, rather than using a fullwidth reference to a value in the blockstate registry, which would be 4 bytes on most systems, it has a smaller palette that it references instead

if there are, say, <=16 different blockstates in a chunk section, the palette will only have 16 entries; and each blockstate reference can be represented with 4 bits, since 2^4 == 16

so to make sense of those references, the client also has to be sent the palette being referenced

[little canyon]

Can someone help me with the protection stones pre 1.13 plugin?
I want it to:

DM for more info

[thorn isle]

i assume you're trying to implement this yourself?

[native gale]

No, I'll use the hack you suggested

Oh, you're not talking to me, sorry

[thorn isle]

just trying to determine whether i should clown emote him or not

[tranquil pecan]

should i use a global task to check if a player holds an item for 5 sec or per player?

(Just making a Lobby PvP plugin)

[thorn isle]

the bukkit scheduler isn't very good

if there's something you have to do every x seconds for y targets, where x is a constant and y is variable, it's better to have one task iterate over y rather than have y tasks in the scheduler with one target

[tranquil pecan]

okay

[tranquil pecan]

then what should i use Executor Service?

[thorn isle]

for asynchronous tasks, yes; for main thread tasks, no, you're stuck with the bukkit scheduler

[native gale]

For async tasks I usually use normal JVM async primitives, and when I need to feed the results back into Bukkit in the end, I schedule a synchronous task inside of async env

I believe it is the intended purpose of scheduling a task without delay

[umbral ridge]

whats the easiest way to copy/place blocks (predefined set of blocks) with code?
I was thinking of placing the existing structure somewhere innaccessible to a player, and then once I need that structure, I would copy each blocks and apply its rotation data etc.. to a new location.

if I have a small house, eg.: 15x15x15... would it take long to copy/paste with code?

i need it to be efficient, but at the same time, I don't want to use worldedit, because it would be kinda stupid to use it just for.. that. I won't need worldedit once the server is in production

[young knoll]

Why not just use the structure api

It’s like schematics but vanilla

[umbral ridge]

Hmm.. I wasn't aware of it :D .. can you give me a class name?

[young knoll]

Structure

[umbral ridge]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/generator/structure/Structure.html?

[young knoll]

Just make sure it’s the right structure class… there’s like 3

[umbral ridge]

this requires me to do a whole lot of things

[young knoll]

Not that one

The one in org.bukkit.structure

[umbral ridge]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/structure/Structure.html

How do I use this

this doesnt take any kind of blocks set

Ill probably have to do it myself... this seems like its over engineered for me

[young knoll]

It can be loaded from a file

Or from a point in the world

[umbral ridge]

But it doesn't take a file anywhere

[young knoll]

StructureManager

[umbral ridge]

ohh I see, so Structure can be a schematic?

[young knoll]

It’s an NBT file

Not the same format as a schematic

[umbral ridge]

how do you create one? if I build a house and want to save it as NBT

[young knoll]

But FAWE can save your selection as a structure file (I don’t think normal worldedit can)

Or you use the structure block in game

[umbral ridge]

with the structure file, are entities and all of the rotation data saved too?

eg. paintings, armor stands

[young knoll]

Yes

[umbral ridge]

perfect

so I have to first load litematic files and then save them as nbt, too much work 😿

[young knoll]

Might exist a converter somewhere

[slender elbow]

yes, it's called Minecraft

load it up, save it as a structure :^)

[umbral ridge]

ill save you as a structure emily

[tight cliff]

PersistentDataContainer is just a part of nbt under minecraft:custom_data right?
and bukkit or spigot can read write that data by PersistentDataContainer.
Then why does it not have a way to use nbt data directly?
It's already doing it in PDC isn't it?
I know I'm miss understanding how it works so please teach me where and why I'm wrong.

[smoky anchor]

You can't really use NBT directly. It's save data.
To get the NBT of an entity or something you need to save it, do modifications there and then load it again.
Which would be stupidly slow if you want to do many changes on many entities. For example just setting health.
You have API methods for that, they directly modify the value on the object, no saving/loading.

And NBT can change at mojangs will, for example Health -> health
If that were to happen, your plugin will stop functioning. You use the API that is (somewhat) stable and won't break as easily.

anyone, feel free to correct anything :)

[tight cliff]

I think I got it.
It's logically possible but not stable so api don't give access directly.
Thank you for detailed reply.

You could make it grow with the scale attribute

or can I just do it without .requireNonNull

[eternal oxide]

You can do without. All it does is quiet an IDE warnign about a possible null

[thorn isle]

it changes nothing in terms of program behavior

but it does mean that when another dev looks at your code later, they'll know that you're aware of the static nullability but expect it to never be null in practice

That's not how you register listeners

alright thanks i'll try

Bukkit needs to know the listener exists, if not it will just sit there

Material.matchMaterial

aight thank y'all ill try that rn

[outer ember]

There is something wrong with my block displays
when it goes into a block
it turns to BLACK
it's seems normal
but it destorys everything
i dont want it
what should i do

[thorn isle]

set its light level/brightness manually

an entity inherits its light level from the location it is in, and solid blocks always have a light level of 0, since light cannot go into them

so if you place a block over a display entity, it will appear dark

[outer ember]

what's a block display default brightness

[young knoll]

There isn’t a “default”

It depends on where it is

[outer ember]

whats its full brightness

[thorn isle]

15 sky 15 block

[outer ember]

Ok thanks but how to set the brightness then

[pale lava]

some of the versiions from BuildTool build/compile the wrong version.

"java -jar BuildTools.jar --rev 1.21.2" installs 1.21.3
"java -jar BuildTools.jar --rev 1.21.9" installs 1.21.10

is this intentional or a bug and where should this be reported if so

[eternal oxide]

intentional

[pale lava]

if a plugin uses one of these versions how do i obtain said versions then if i cant from build tools

[eternal oxide]

you use teh released version

deprecated versions are usually removed due to a bug/exploit

[pale lava]

gotcha so the plugin should update those versions then, they support previous versions and have those as dependencies, i guess they should move the version up until it gets to one that isn't deprecated

[eternal oxide]

correct although minor versions are usually code compatible with prior

so a .5 will run fine on a .6 server

I want this to work.

[elder lichen]

[chrome beacon]

well yeah that's not going to work

You can't just randomly cast stuff

[elder lichen]

Do you want to help me figure out how to do it? The easiest way?

[chrome beacon]

I'm not going to write it for you that's what you're expecting

[elder lichen]

Can you at least give me a hint on how to do it, because apparently it's much harder to do it on Spigot on this version than on 1.20.1?

[chrome beacon]

as I mentioned you can't just cast a list of entry to server player

also I'm not sure what "this" version is

[elder lichen]

I don't understand

[chrome beacon]

You said it's much harder to do on "this" version

without specifying what "this" version is

[elder lichen]

version of Minecraft that on 1.20.1 I made a table without problems with fakeplayer and it works, but on 1.21.8 it is much more difficult

[chrome beacon]

I don't recall there being much of a difference

Anyways start by fixing that cast

[tranquil pecan]

List<Entry> entries = new ArrayList<>();

[wide crescent]

What's the normal value for permissionDefault? I want logblock to be accesible for everyone

tool:
leftClickBehavior: NONE
item: WOODEN_PICKAXE
defaultEnabled: true
mode: LOOKUP
dropToDisable: false
removeOnDisable: true
aliases:
- t
params: area 0 all sum none limit 15 desc since 60d silent
canDrop: true
rightClickBehavior: TOOL
permissionDefault: OP

[chrome beacon]

That sounds like a question for #help-server

though in general you'd manage your permissions with a permissions plugin like LuckPerms

Assuming that uses the permission default enum set it to TRUE

[wide crescent]

I took OP from myself and it works so I assume it should be done, thanks

[elder lichen]

this.playerConnection = ((CraftPlayer) player).getHandle().c;```

spigot 1.21.8 what will it be like now?

[thorn isle]

https://mappings.dev/1.21.8/net/minecraft/server/level/ServerPlayer.html

tip: first check the version you're migrating from, find the member's intermediary mapping, and then just ctrl-f for it in the version you're migrating to

[hard socket]

how can I hide this bundle info?

[sacred mountain]

anyone know how mannequin hitboxes work

[chrome beacon]

tried hide additional tool tip itemflag?

[sacred mountain]

1 sec another couple images sending

like what the hell

moyang why

any way to even know when the player clicks on another part of the entity that isnt in it's hitbox

or is this just a limitation

[winged scaffold]

join vc 1 for free development on your server

[chrome beacon]

Don't post in every channel nor advertise your services here

[sacred mountain]

anyone know?

for context this is a sleeping pose mannequin entity

[drowsy helm]

you could maybe modify it's aabb hitbox

but you'd have to calc it yourself

[sacred mountain]

i would need nms for that i assume

[drowsy helm]

uh it might be in api

[thorn isle]

i'd spawn an Interaction entity for that

or manually raytrace clicks near the mannequin

crawling/sleeping/swimming pose hitboxes aren't really representable with aabb's since they can rotate, which aabb's can't

so some manual raytracing is in order if you want to do it accurately

for specifically lying in a bed, where the rotation is guaranteed to be axis aligned, you can still use interaction entities

[sacred mountain]

honestly i don't like the way minecraft does hitboxes in general

so much more annoying than other games i've modded

or made plugins for

[thorn isle]

aabb's make sense for a block game and are cheap and easy to deal with

just they don't work for things that can rotate and aren't approximately the same size in x/z

[sacred mountain]

guess so,

are villager hitboxes the same when they sleep

[thorn isle]

probably

[sacred mountain]

lmao

they dont even have one when theyre asleep i think its a block event to wake them up

[thorn isle]

you can click them, i remember opening the trade gui while they're sleeping, but it's very finicky

[sacred mountain]

i'll probably use an interaction entity in that case, i didnt even know they were a thing lol

[young knoll]

You’ll need 2 interaction entities if you want accurate detection

Since they cannot have a different width and length

[sacred mountain]

good enough lmfao

i might create an algorithm to make custom sizes out of several of these entities

i mean they have tags so shouldnt be too bad

dm me for a fullstack dev if you need help with ur server

bro how many times do you want to post lol

    }

why do i get that subchannel is "premiumvanish:main" and not the one i want?

[buoyant viper]

how are u sending the plugin message?

[ocean gorge]

public void notifyNewTicket(Ticket newTicket, Player senderPlayer){
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        DataOutputStream out = new DataOutputStream(stream);

        try{
            out.writeUTF("Forward");
            out.writeUTF("ALL");
            out.writeUTF(EndlessTickets.TICKET_SUBCHANNEL);

            ByteArrayOutputStream msgstream = new ByteArrayOutputStream();
            DataOutputStream msgout = new DataOutputStream(msgstream);

            msgout.writeUTF("NEW");
            msgout.writeInt(newTicket.getId());

            out.writeShort(msgstream.toByteArray().length);
            out.write(msgstream.toByteArray());

            senderPlayer.sendPluginMessage(plugin, EndlessTickets.VELOCITY_CHANNEL, stream.toByteArray());

            plugin.getLogger().info("Network notification sent for ticket #" + newTicket.getId());
        }catch(IOException e){
            plugin.getLogger().severe("Network message encoding/sending error: " + e.getMessage());
        }
    }

this works, because the log appears

[buoyant viper]

honestly, no clue

from what im [attempting to] read [on my phone], ur subchannel should be Forward?

oh thats a bungeecord messaging channel command, huh

[ocean gorge]

yeah, it's an in-game support ticket system, however i only get that subChannel is "premiumvanish:main"

it doesn't make sense like that

[buoyant viper]

https://docs.papermc.io/paper/dev/plugin-messaging/#plugin-message-types

is VELOCITY_CHANNEL set to "BungeeCord"?
