right before this line in the manager

                consoleLogger.addHandler(consoleHandler);
#

add

#

consoleHandler.setLevel(Level.ALL)

heavy fulcrum
#

alright

zinc iris
#

that should fix it

eternal oxide
#

Pretty sure .setLevel no longer works. It broke long ago when Bukkit changed the backing logger

zinc iris
#

damn

#

did not know that

eternal oxide
#

yeah its a bitch

heavy fulcrum
#

I can set something like.. if the int value of the level is greater than or equal to that of info, send the message to discord

#

Here's some kind of warning
[17:14:06 WARN]: Nag author(s): '[]' of 'DTMBridge v1.0' about their usage of System.out/err.print. Please use your plugin's logger instead (JavaPlugin#getLogger).

zinc iris
#

oh ye thats just cause we were using sout to debug

heavy fulcrum
#

ah right

heavy fulcrum
zinc iris
#

ill look at it some more but its 6am and im tired af so ima sleep and hopefully while i sleep someone else can help or knows the answer

heavy fulcrum
#

always works when i reload the server instead of restart

zinc iris
#

like /reload

heavy fulcrum
#

yep

zinc iris
#

weird

heavy fulcrum
#

maybe i could set some sort of delay after the bot is initialized..

smoky anchor
#

Sorry, can you tell me what ConsoleDiscordHandler is supposed to do ?

heavy fulcrum
#

Its a Handler for the Logger which is supposed to log to a Discord channel

smoky anchor
#

So, anything that would be shown in the server logs, should be sent to discord

heavy fulcrum
#

yes

#

caught this while using /reload:
[net.dv8tion.jda.api.requests.RestRateLimiter] Waiting for 1 requests to finish.

smoky anchor
#

Can you, as a test, create a Filter and add it to the Logger ?
Just sout the LogRecord or something.

heavy fulcrum
#

Well, I'm kinda tired now. I'll see if I get some time later. Thanks for all your help

zinc iris
#

When I wake up ima clone your hit and mess around myself

heavy fulcrum
#

Thanks dude

#

In the mean time, I'll see how the dev of DiscordSRV did it.

zinc iris
#

Like 10 mins ago

#

He uses log4J basically

smoky anchor
#

Seems it uses Filter as well, but from log4j

heavy fulcrum
#

Could you name or link the classes which he used?

#

I'm kinda having a hard time.

smoky anchor
#

(actually I might be completely wrong)

heavy fulcrum
#

I'm gonna have to deeply study logging if I want this to work correctly. Thanks though.

zinc iris
heavy fulcrum
#

The main class is really, really big. Wow.

#

ye

and then he uses another thing he made

I need help to replace a deprecated method in order to provide support for 1.21.4

#

Why has Biome.values() been deprecated and made unavailable?

young knoll
#

Because it’s not an enum anymore

#

Use Registry.BIOME

native bison
#

bruh

young knoll
#

You can then use the stream method and whatnot

#

Thanks... not a fan of Regitries

Why not

It allows for custom biomes uwu

so have a few dumb questions, made a second module in my project for api so third party plugins can hook. My question is, how do I compile the api in the core module? atm the api is <package>pom</package> do I need to shade it into the core or what's the process?

remote swallow
#

shade it in the core or shade them both in the parent

Nice, ill try shading it in the core 🙂 ty

Is there a way to transform a JAR file into a IntelliJ Project?

#

I'm restoring an old private project which original code has been lost, except its .jar

remote swallow
#

you can decompile it but you wont get the exact code

#

it will be decompiled code which can be very broken sometimes

Question is there an event for when a player loads a chunk into render?
I am using nms and packets to spawn npc's and I need it so that when a new player loads a chunk with an npc in them they get sent the packet so the npc shows up for them

chrome beacon
#

There isn't

#

You'd need to use nms for that part as well

#

or you know not reinvent the wheel and just use Citizens

pliant topaz
oblique igloo
#

I'm not reinventing the wheel, I'm doing very specific things with npc's that citizens and their api doesn't allow for and I really don't want to use 50+ api's in a plugin.

native bison
pliant topaz
oblique igloo
#

Awesome I seen ChunkloadEvent but not PlayerChunkLoadEvent on the javadocs. Thanks

chrome beacon
#

That event is not part of the Spigot API

#

It's Paper only

remote swallow
pliant topaz
#

oh f

#

been in the wrong docs again sorry

#

wait

#

but in Chunk

oblique igloo
#

Damn I really don't wanna use paper's api for just that.
My other option was to listen to the player move event, and check when they enter a new chunk if it contains my object. But that feels kinda bad for performance

pliant topaz
#

theres a method to get all the olayers seeing the chunk

chrome beacon
#

^^

#

You'd need to check that every couple of ticks

#

for every chunk

#

Which uhh is not great for performance

oblique igloo
#

Yea that still kinda feels bad imo

pliant topaz
#

yep

#

but seems to be kind of the only api-only way

#

except the move event ofc

entity-tracking-range
Default: (display: 128, players: 48, animals: 48, monsters: 48, misc: 32, other: 64)
Type: Integer
Description: Controls the range in blocks that entities will become "visible" or otherwise known as "tracked" to the client. Entities outside of this range will be invisible as they are not being rendered to preserve CPU usage and bandwidth. This is particularly useful for PVP servers, as turning down the player range will 'nerf' wallhacks and radar to some extent. Miscellaneous controls the range for item frames, paintings, dropped items, and experience orbs. Other is a general maximum limit for all entities on your server.
Does not impact server performance much to change these values. These will mainly help client-side lag when lowering these.

#

you should read this config value and calculate the distance between you and the npc

#

it shouldnt be handled on chunk basis

Any ideas how to deepcopy a ConfigurationSerializable and change a value that is final during that?
I tried it by serializing and then deserializing but that is just a shallow copy.

My next attempt was to use gson but it turned some of my nested ints into doubles, breaking the config

My last attempt (see below) was to create a temporary yaml configuration, write the object, save and read the object again, this however won't let me change values before reading it again as the commented line causes the whole Object except the freshly written field to be removed.

    public Integer duplicateActivity(int id) {
        ConfiguredActivity activityToCopy = getById(id);
        YamlConfiguration tempConfig = new YamlConfiguration();
        tempConfig.set("copy", activityToCopy);
        //tempConfig.set("copy." + ActivityBaseField.ID.configKey, currentHighestId++);
        tempConfig.saveToString();
        ConfiguredActivity newActivity = (ConfiguredActivity) tempConfig.get("copy");
        addActivityInternal(newActivity);
        return newActivity.getId();
    }

If you have a question, please just ask it. Don't look for staff or topic experts. Don't ask to ask or ask if people are awake or available. Just ask the question to the channel straight out, and wait patiently for a reply. Make sure you use the right channel regarding the topic of your question.

# final sapphire Just wondering if anyone could help me with this small plugin I am making, I've ...

Rough Idea:

So I want to make it so that when you join the server, the plugin will check if you have one of the following permissions 'ascension.team' or 'abyss.team'

If you have neither, a command will run to give you a luckperms group (either ascention or abyss) and the way it does it is by balancing the players in each group. If 10 people join, there will be 5 people on Ascention team and 5 people on Abyss team.

The plugin should check Luckperms to ensure the teams don't change size when players log off the server or should adjust the size of teams if players switch teams using another plugin.

Issue:

When a player logs on or off, the team size of what ever team they are on keeps on increasing.

I have never coded in my life before so and am using ChatGPT to code so I have most likely done something wrong. It would be greatly appreciated if someone could help me out!

Ping or DM me if you can help. Thank you (will be gone for about 1-2 hours)

flint coyote
#

But of course it needs a new ID so it's more than just a copy

#

I guess I'll just do a copy constructor that also allows the new ID

north nova
flint coyote
#

I mean I have that but since the Class contains maps it's not as simple as to just reach the map from the other object in because that would just hand in a pointer

north nova
#

new HashMap<>(oldMap)

flint coyote
#

So I have to specifically deepcopy those, but I can do it in a seperate constructor

#

yeah

north nova
#

so whats the problem

# 
Constructor(Map<Object, Object> map) {
    this.map = new HashMap<>(map);
}```
flint coyote
#

Nothing, I was just hoping for something less bloaty since there's quite a few fields and I have to nullcheck a bunch of fields

#

And I thought "Oh I can already serialize it, so maybe I can just serialize and deserialize somehow"

flint coyote
north nova
#

why would it not go well with null wdym

flint coyote
#

if you call that with null it will give you a nullpointer

# 
        Map<Integer, Integer> failureActions = null;
        if (failureActionIdsWithDelay != null) {
            failureActions = new HashMap<>(failureActionIdsWithDelay);
        }

So I basically have to do this all the time before calling the constructor

north nova
#

this.failureActions = failureActionIdsWithDelay == null ? null : new HashMap<>(failureActionIdsWithDelay) is a cleaner one liner i guess

flint coyote
#

yeah true, saves some lines. I'll take that

#

thanks

north nova
#

no worries

inner mulch
flint coyote
#

While this is true for just one field, it would require me to do that for all possible combinations and have a bunch of constructors that have call constructors. I decided to go with a non constructor based approach which is just

objectToCopy.copyWithNewId(newId);
#

And then calls the constructor internally with the one line null checks

Hey there, I am trying to create the effect of a player dying and dropping his inventory without actually killing the player.
I want to do this because I prevent the player from dying and instead instantly make him a spectator.

Does anyone have an idea how I can do this with the lowest possible performance impact?

I already considered to loop through the players inventory and spawning the items piece by piece as entites but that seems like too much brute force from my point of view.

inner mulch
#

at the same location

eternal oxide
#

you can call dropItem on the player

flint coyote
#

isn't that just for the item in the players hand?

grim dock
eternal oxide
#

thers lots of them

#

if you really want to simulate teh player dying then world#dropItemNaturally

flint coyote
#

I would personally go with respawning the player and setting the respawn location to their position as this causes the least amount of noise for other plugins

#

But if compatibility is not an issue then it's just looping the items. It's not even 50 iterations, that shouldn't cause any performance issues

grim dock
eternal oxide
#

just getcontents/armor and drop each item

flint coyote
#

Don't you wanna drop all items?

grim dock
flint coyote
#

Oh. No you can't. You'll have to loop and do World#dropItemNaturally. Either that or you'll have to loop and set the item in the players hand to then drop it.
The latter would cause the PlayerDropItemEvent to fire for each item, which is probably not wanted.

#

And don't forget to clear the players inventory afterwards

grim dock
north nova
#

cancelling the event & dropping the items afaik will not have the death animation

fierce salmon
#

Just curious, what would someone use runtasklaterasynchronously for?

inner mulch
#

examples are chat, tablist, scoreboards

#

or anything else

fierce salmon
#

Oh okay

#

And whats the difference between something being on and off the main thread?

inner mulch
#

it can run in parallel and you make use of the cores of ur pc, altough im not sure what runtaskasync does internally

fierce salmon
#

Ok

young knoll
#

It offloads it to a thread pool

#

As for how those threads are managed, that’s up to the OS and the JVM

mortal hare
#

when you're building a texture atlas, does it usually needs to be inside a grid (just like minecraft did prior to resource packs, they sill iirc build texture atlases dynamically) or can you make it gridless and hardcode the positions of the texture itself onto the object?

#

what's the best way

grim dock
drowsy helm
ebon topaz
#

ok so i can use tool component to set the mining speed right?

ebon topaz
#

also yk how if you try and put sharpness on a pickaxe and it doesnt work or if you use command and it says unsupported enchant for that item, how do i add enchants to that list? so for example make it so my itemstack cant be enchanted with fortune

rough ibex
#

You cant afaik

#

its based on the id

smoky anchor
ebon topaz
smoky anchor
#

iirc you can simply change the attribute

ebon topaz
#

is that with setAttributeModifiers?

smoky anchor
ebon topaz
#

yeah ive been looking at the docs but i think i seem to make a new tool component instead of editing the oringnal one because after i change it i cant mine blocks

smoky anchor
smoky anchor
#

Why do ToolComponent.ToolRule methods return Float and Boolean ?!
edit: should have read the full description

ebon topaz
# 
public ItemBuilder setMiningSpeed(double speed){
    ToolComponent tool = meta.getTool();
    tool.setDefaultMiningSpeed((float) speed);
    return this;
}
smoky anchor
#

read docs of getTool
Gets the tool set on this item, or creates an empty tool instance. The returned component is a snapshot of its current state and does not reflect a live view of what is on an item. After changing any value on this component, it must be set with setTool(ToolComponent) to apply the changes.

#

so at the very least you'd have to do meta.setTool(tool);

ebon topaz
smoky anchor
#

No you're not

#

If you can, please paste the whole ItemBuilder class
But I doubt you are if the setMiningSpeed is complete

undone axleBOT
robust helm
#

when using markers for spawnlocations of specific minigame events like player spawn points or item generators, should i use customname or metadata?

smoky anchor
#

Neither, use PDC for the Marker entity

chrome beacon
#

?pdc

undone axleBOT
ebon topaz
#

so i think what ive found out is that there is no tool components on itemstacks unless you specifically set one which means there is no default to go off

smoky anchor
ebon topaz
#

yeah attempting to set the mining speed of a default pickaxe

smoky anchor
#

If you were to do it somewhere else, you would have no access to that modified ToolComponent, each getTool returns a new copy. As stated in docs.

ebon topaz
# 
public class ItemBuilder {
    private final ItemStack item;
    private final ItemMeta meta;
    private final ToolComponent tool;


    public ItemBuilder(Material m, int amount){
        item = new ItemStack(m, amount);
        meta = item.getItemMeta();
        tool = meta.getTool();
        getLogger().severe(String.valueOf(tool.getDefaultMiningSpeed()));
    }

    public ItemBuilder setItemName(String name){
        meta.setItemName(name);
        return this;
    }

    public ItemBuilder setMaxDurability(int durability){
        Damageable damageable = (Damageable) meta;
        damageable.setMaxDamage(durability);
        return this;
    }

    public ItemBuilder setMiningSpeed(double speed){
        tool.setDefaultMiningSpeed((float) speed);
        return this;
    }

    public ItemStack build(){
        getLogger().severe(String.valueOf(tool.getDefaultMiningSpeed()));
        meta.setTool(tool);
        item.setItemMeta(meta);
        return item;
    }
}
smoky anchor
ebon topaz
#

when i get the pickaxes tool component there is nothing set such as the blocks it can break

smoky anchor
#

ok, your ItemBuilder looks correct.
You can still try using the attribute, I do believe there is a way of getting default attributes, so overriding them should not be much problem.

ebon topaz
#

yeah its looking like the attribute way is the easier way

Guys, I want to have an object (of a class that doesnt implement AutoCloseable) saved in an array, but when I access that object via a method I want it to return a class that has the same methods as the first class but it also implements AutoCloseable. Is that possible?

chrome beacon
#

xy? Why do you want to do it that way?

glossy laurel
#

cuz the only way I can imagine that is breaking inheritence logic lol

eternal oxide
#

So long as you use a getter you can cast it

glossy laurel
#

like, that's not possible right?

eternal oxide
#

You specified no limitations in parent/child design

glossy laurel
#

well thats how I imagine it should be done

ebon topaz
# 
for  (AttributeModifier am : meta.getAttributeModifiers(Attribute.MINING_EFFICIENCY))
  getLogger().severe(am.getName());

Cannot invoke "java.util.Collection.iterator()" because the return value of "org.bukkit.inventory.meta.ItemMeta.getAttributeModifiers(org.bukkit.attribute.Attribute)" is null

eternal oxide
#

Why do you want one auto... and the other not?

glossy laurel
ebon topaz
#

im checking a pickaxe though

smoky anchor
glossy laurel
smoky anchor
#

Well, you're sorta correct, I jumped the gun
You need to get the default attributes of the item

glossy laurel
eternal oxide
#

I see no reason for it

glossy laurel
#

fr

eternal oxide
#

Why not just have it auto... it makes no difference if it implements and is not used

eternal oxide
#

you are doing all this to avoid an IDE warnign of unused methods?

#

how safe is .clone()

#

can I use it out of the box

eternal oxide
#

depends on your Object

glossy laurel
#

which parts of it specifically?

eternal oxide
#

what field types it has

#

mostly its quite safe

glossy laurel
#

what field types are bad

eternal oxide
#

Can't remember. Its been many years since I used cloneable

glossy laurel
#

alr thx

hazy parrot
#

just use copy constructor

#

whole cloneable api is shit

ebon topaz
glossy laurel
eternal oxide
#

clone is fine, at least it does a shallow copy so will not clone other object references

#

I've done both in the past and it really depends on your object and requirements

hazy parrot
#

effective java have a good chapter about it

smoky anchor
hazy parrot
#

Given all the problems associated with Cloneable, new interfaces should not
extend it, and new extendable classes should not implement it. While it’s less
harmful for final classes to implement Cloneable, this should be viewed as a performance optimization, reserved for the rare cases where it is justified (Item 67).
As a rule, copy functionality is best provided by constructors or factories. A notable exception to this rule is arrays, which are best copied with the clone method.

#

Is there any attitude among the plugin development community towards <nullException vs null check> ? which is better?

eternal oxide
#

check over Exception. Exceptions shoudl not be used to control teh flow of code

#

at least that was teh idea a few years ago, unless its changed

upper hazel
#

“Nullexception” is less productive than ‘if’ but if I make an api it gives the convenience of understanding the error for api users

#

idk what to do

#

especially for intermediate objects

smoky anchor
#

I think it's better to yeet an error when user does something wrong than to just silently fail and leave the user to wonder what went wrong. In the API case.

upper hazel
#

so many factors

slender elbow
#

if you are making an api that its method mustn't take null arguments then do note in the javadoc that it throws NPE if the params are null and just slap a Objects.requireNonNull(foo, "foo is null"); at the beginning

#

if null is a valid argument value then annotate the parameter with some @Nullable annotation and handle that as a value

#

you'd probably have to create your own personal database for that for tracking that

the world on which all offline players are located

chrome beacon

Use getLocation

kind hatch
#

You can get that info from the OfflinePlayer object.

#

Oh hey, I added that method. lol

cedar turtle
#

So I don't have to read out every single player file with NBT? As I said, it's about old data

kind hatch
#

Unless you need more data that the world they are in, no.

You can just iterate over #getOfflinePlayers() and use #getLocation().getWorld().getName();

I tried explosion and that’s too small and not how large explosion used to be. It would suck if I only have those two, but I’ll compare them later

I don't think hasPlayedBefore() will ever be false because getOfflinePlayers() is going to get a list of players that have played on your server

fossil cypress
cedar turtle
eternal oxide
#

IF you have a LOT of players, yes

#

depends what you are going to use it for

worldly ingot
#

tbh I'd do it async anyways. It does lots of file IO

slender elbow
#

you can also not consent for it to do file io

#

very good strategy

worldly ingot
#

Just say no and it legally can't do IO

cedar turtle
# slender elbow you can also not consent for it to do file io

I didn't understand that correctly. So I mainly need it to know who is on it if I want to renew a world. Or recently when I changed a multiinv plugin that I could inform players to go into a world to not lose the inventory. I hope that makes some kind of sense 🙈

It's a read only operation, so no, you cannot change the location of the offline player.
Not sure what you mean by that second question.

#

Setting the player location could be added in another PR, but I feel like there are more challenges/things to consider with an addition like that.

cedar turtle
#

there is also no other method to change the location of an offline player? with the second question I meant dependencies such as a multi inv plugin. That this is also taken into account when changing the location.

Hi everyone,

I’m currently trying to understand how the underlying Minecraft and Bukkit code works by going through a stack trace to see what’s being called in the background. While doing this, I noticed something strange: the line numbers in the stack trace don’t match the lines in the decompiled code.

and why not just clone the spigot repo and apply patches?

#

The bytecode contains line numbers

#

but decompilers won't try to match the code exactly

#

well match the line numbers*

zenith bobcat
#

but why is the decompiled code at the wrong linenumbers

chrome beacon
#

Because it's decompiled

#

It tries to generate java code that matches the behavior of the bytecode

#

It does not have access to the source code so can't it know what types of syntax sugar you used when compiling

#

or if you decided to combine multiple lines of code

zenith bobcat
#

so it don´t accually contain the line numbers

chrome beacon
#

The bytecode does contain line numbers

graceful meadow
#

Just run the BuildTools and load spigot project in IJ

zenith bobcat
chrome beacon
#

It contains the line numbers of the source

#

yes

#

That's how java knows what to put in the StackTraces

Note that due to the nature of explosions, BlockEvent.getBlock() will always be an air block. getExplodedBlockState() should be used to get information about the block state that exploded.

You want to check what exploded not what's being broken by the explosion

Hey, so I have a little problem that the world is null but the world really does exist. Could anybody help me?

Based on the context from my codebase, it seems that I am having an issue with the teleportToLastCheckPoint method in the CheckPointSystem class. The issue is that the teleportToLastCheckPoint method is trying to teleport a player to a location that has a null world.

Main Class: https://hastebin.com/share/tejosoqaya.java

gotta kidding me right? Did I screw up when I copied and then pasted and changed ver numbers from 1.21.1

wet breach
#

Lol

remote swallow
#

its always the simple issues that cause the most trouble

shy belfry
#

it's always a stupid mistake that causes you the most trouble now to twiddle my thumbs for a minuet while it builds and hope for no red

#

aye build success thanks y'all

remote swallow
#

we never expect simple issues anymore, np

shy belfry
#

here I was deleting my 1.21.4 build folder in m2 home and rebuilding thinking maybe I forgot a command argument

remote swallow
#

i was gonna say did you run bt with --remapped and then read the error and saw it and thought that might cause a few issues

kind hatch
#

I think I saw someone use maven variables for that section so they wouldn't have to change the version numbers every time.

#

Might try to set that up in my multi-module projects. :3

shy belfry
#

I would forget it if I didnt make a build script where I just type the version number and it goes

#

versionBumper.sh is what I have for staffplus a little script I made with the help of google lets me type what version I want staffplus to be and it goes through and does it so I dont have to go thru 15 modules and do it by hand

remote swallow
#

afaik you could do something like ```xml
<properties>
<minecraft.version>1.21.4</minecraft.version>
</properties>

<srgIn>org.spigotmc:minecraft-server:${minecraft.version}-R0.1-SNAPSHOT:txt:maps-mojang</srgIn>

#

then just use ${minecraft.version} everywhere instead of changing 50 variables

shy belfry
#

for that yes but I need each module to have the same project number as far as I know

#

so script it

kind hatch
remote swallow
#

the R0.1 bit never changes

kind hatch
#

It used to

remote swallow
#

i dont think thats ever not be R0.1 since like devbukkit days

shy belfry
#

I think it did for like 1.7 and 1.9

remote swallow
#

they dont get any fancy nms so it should be fine to use that or something along those lines

wet breach
#

I will show you

shy belfry
# 
``` is how I do it now the script just goes thru all subfolders \
wet breach
#

So the way i have it setup it currently changes version number in plugin.yml to be same as pom version

shy belfry
#

well that certainly seems easier

wet breach
#

It is flexible in its configuration too

#

You change multiple files in multiple directories and accepts regex

shy belfry
#

Imma have to go look into that plugin

wet breach
#

Token in my example is what it looks for. In this case anywhere it sees maven-version-number it will auto replace

#

You can see my plugin.yml has that specific string lol

wet breach
wide cipher
#

I have this code using org.json ```String decoded = new String(Base64.getDecoder().decode(base64));

// Extract the "textures" JSONObject
JSONObject textures = jsonObject.getJSONObject("textures");

        // Extract the "SKIN" JSONObject and then the "url"
        url = textures.getJSONObject("SKIN").getString("url");
    } catch (JSONException e) {
        throw new RuntimeException(e);
    }

hey guys, I am currently trying to set a lot of blocks within an area (millions), and I got to the point of using nms chunk sections to do the trick. It is INCREDIBLY fast, however, there is a lighting issue that follows when trying to use it. I tried to mitigate the issue using player.sendBlockChange, but that is just a temporary fix. I found some forum threads and they suggested to update the chunk itself, but all of the methods were outdated. Has anyone else gone through this? Thanks for the help!

buoyant viper

nova notch
#

your loss

buoyant viper
#

quite frankly i think i lose nothing

river oracle
# nova notch adventure...?

adventure isn't proper on spigot anyways, the only reason its "cursed" is precisely because there is no native integration

#

the entire concept of audiences is a pain in the ass

echo basalt
#

I kinda need to deal with this at work and it's a lot slower than expected so I might be missing something

#

Running on a 6-core 10 year old xeon

#

For some reason multi-threading block pasting makes it like 50% slower than just running workdistro

wraith dragon
#

its pretty insane

#

just the lighting problem

echo basalt
#

I'm only achieving like 300k ish blocks a second which is fairly small for what I'm doing 👀

#

hoping for at least 10 million

wraith dragon
#

this was the guide I refered to

#

the third one

#

nms chunk sections

#

the last one is EVEN faster

#

but its got a lot of cons

#
  • I dont need it that fast lol
echo basalt
#

yeah I'm basically doing that

#

nvm I'm doing #2

wet breach
echo basalt
#

yeah I can prolly use it

#

I'm assuming it has to do with writing directly to either the data palette or nbt files

#

problem is that this cpu's multicore is doodoo and the guys don't want to invest more in the testing network for now

wet breach
#

If you want fastest speed possible you do it with server off and just modify the region files directly

echo basalt
#

because we're like 4 months late

#

We only need these to be in-memory and I'm pretty sure manipulating ram is quicker than packing ram and unpacking it again

wet breach
#

You can easily modify thousands of region files with direct approach

echo basalt
#

Yeah but is it any faster than modifying millions of blocks in another thread

#

because IO is a thing

#

as long as we keep a thread for each chunk section there's no need to lock stuff

wet breach
#

No locking needed if server is off

#

But ssd's are fast

echo basalt
#

IO is still a thing

#

we're CPU-bound not disk bound

#

this is a low-latency scenario

wet breach
#

On average a region file is like 1mb if empty 10mb if filled with somethings

wet breach
#

Its not like your using some pentium

echo basalt
#

we're using a really old xeon

#

with a whopping 6 cores

#

clocked at like 2.3ghz

#

I bet if we switch to a proper ryzen / threadripper it'll do good

#

but that's not my decision

#

BTW this is for pasting +-12.5 million blocks across a ~1100 x 1100 area

wet breach
#

That is plent good to manipulate thousand of files in one go

echo basalt
#

At the moment pasting a 47x47x47 structure takes +- 200ms

wet breach
#

You will hit your ram limit before you bogged the cpu down with region files

echo basalt
#

don't forget we still need to pack data

#

Switching from just queuing stuff to the main thread -> yeeting it to an executorservice increased the pasting time by 100ms

#

which is crazy

#

context switching is not a homie

wet breach
#

Manipulating files is not slow

echo basalt
#

packing a bunch of bytes, compressing etc is a lil

#

slower than just writing data to a data palette

wet breach
#

Not with direct manipulation

echo basalt
#

I disagree but cba arguing with you at 5am on a saturday

wet breach
#

One of these days i will write a test to show you can do millions in matter of seconds

wraith dragon
#

optimization TO THE MAX

echo basalt
#

seconds is a bit too much

#

I need less than that :)

wet breach
#

You need to leverage what the OS can do for you. If you write it properly your limitation is going to be open file handles

#

I wouldnt even use java for the direct approach except to initiate the process

#

But java is sufficient still

#

But your not going to get light speeds out of a computer that isnt using light to process anything

#

But we can get it going fast

#

Anyways, got some tires to do lol

wraith dragon
#

@echo basalt here ya go

#

it might not replicate your situation

#

but here are the profiler stuff

#

#

1 million per second

#

ignore the LearningPlugin

#

#

#

#

#

#

24m blocks

1m per second

#

0.71 ms

#

ill bump up the speed and check it out again

#

@echo basalt btw, do you have any idea on how to fix the lighting issue?

echo basalt
#

there's a way to tell it to do lighting updates

#

something with the light engine

#

serverLevel.getLightEngine().checkBlock(BlockPos)

#

sumn like that

wraith dragon
#

server keeps crashing now

#

I changed the speed to 10m blocks per second

#

just wont work

buoyant viper
echo basalt
#

as long as it beats this 6 core xeon im good

wraith dragon
#

the lighting also crashes me

#

omg

wet breach
#

Better off having a plugin fix lighting when a chunk loads otherwise you are going to have to load every single chunk and then check all params for light conditions lol

wraith dragon
wet breach
wraith dragon
wet breach
#

With spigot if you use the api, most things that interact with the world like that typically have issues with doing certain things async

#

However in modern versions of mc, light updates are separate from the chunks now and have their own file they get stored in

#

So i cant really say in regards to doing the actual light update fixes lol

sullen marlin
#

Why are there light issues anyway? Isn't there a --recreate option built into the server anyway as well

wraith dragon
wet breach
wet breach
wraith dragon

Uh, should be able to look in the world directory and see a directory i think for lighting similar how entity data is stored separately

#

Oh alright, ill check it once I get home, thanks for the help btw

Might be worth investigating that command and how it works internally

#

Might be able to use it somehow for your use case lol

@echo basalt I found something interesting during my playtest, if set the blocks speed enough, it affects the other player's ping more

#

e.g. I set the blocks reset per second to 1m

#

and their ping went to 1k

very odd

They are identical, both getColor from leatherArmorMeta and getDefaultLeatherColor in ItemFactory

However, default is the DEFAULT, it may not be the color you applied

Any1 knows what's the fastest lib for zlib decompression?

proud badge
#

Just use the built in class

#

It runs the native c library, which is fast

grim hound
proud badge
grim hound
#

Same with zlib

#

Just because java uses a native c lib doesn't mean that there doesn't exist a faster alternative

eternal oxide
#

Why? Are you having a performance issue using compression?

#

Just searching for alternatives

#

Like Velocity's lib deflate

#

i was see smth liike this when found plugin for weather

scarlet gate
#

Is it possible to set a default permission for something like plugin.use.*, where * applies to any checked sub-permissions?

eternal oxide
#

it depends

#

Wildcards are not supported by Bukkit natively

#

So you need a Permission plugin that can handle wildcards

#

If you are talkiung about Just your own plugin, then no, you can not create a native wildcard for all variants

#

You could process wildcards within your own plugin though

#

check if the Player has plugin.use.* directly so cover any sub permission

#

if sub permissions are unknown you have to do it yourself

pseudo hazel
#

or just add a permission for plugin.use.all or something

eternal oxide
#

same as using *.

pseudo hazel
#

yeah but you arent fooling yourself

eternal oxide
#

you would still have to check for it

#

LuckPerms handles Wildcards but I don't like recommending it as it hacks Bukkit to do so. GroupManager handles wildcards if you query the plugin directly or check via vault.

#

But if you are writing a plugin that needs to handle wildcards you must do it yourself for compatability

slender elbow
#

I think that as an admin there is a lot of value in a plug and play solution for weighted permission inheritance, context resolution and wildcard resolving without having to scour plugins specifically having to handle those features which might not there be alternatives doing that in the market

eternal oxide
#

Yes, my only reason against LP is that it changes the native behavior of permissions.

The one I have issues with is Bungeecord. My Velocity to paper works fine

#

Is there a dedicated channel for Bungeecord?

eternal oxide
#

yes, this is for both spigot and bungee

#

Many will ignore question which reference paper as its behavior is not always the same as spigots

#

If the issue is repeatable with a spigot server you are likely to get more answers

#

Build against the lowest API you want to support

#

You can use Modules to support higher API versions if you want

#

but the base shoudl be the lowest API version

#

always latest, but depending on what you are doing back as far as 1.18

#

very few servers/players are on lower versions

#

3.7% of servers run 1.8

#

depends what plugin you want to write

#

then you can write it for 1.8 easily

#

1.8 will run on all versions

#

you only need the API so just a normal maven setup

#

yes, but change teh version to 1.8 etc

api-version was introduced in 1.13

yep, it will be ignored in prior versions, but its required to prevent a nag warning in newer versions

Assign the items with unique ids and check if they are similar

Client can skip on sending the inventory close packet

im new i have no idea what that means

I already told you what to do like a week ago?

Ik but it didnt work and then i quit

All you need to do is add the annotations

are there any resources for CustomModelDataComponent() outside of the javadocs? i'm really unsure how to set it up

chrome beacon
#

What about it are you unsure about?

harsh surge
#

I feel like an idiot

#

i was replacing the things with notnull

#

not annotating

unborn hollow
chrome beacon
#

getCustomModelDataComponent -> getStrings() -> add (to new list) -> setStrings -> setCustomModelDataComponent

#

or just set strings directly if you don't care about keeping anything that's already there

unborn hollow

kk i'll try that out

#

item model 🙏

#

items are so cool now

chrome beacon
#

Yeah you can make some cool stuff

unborn hollow
chrome beacon
#

You forgot to set the model data

#

Smth like

var modelData = meta.getCustomModelDataComponent();
modelData.setStrings(List.of("bat"));
meta.setCustomModelDataComponent(modelData);
itemStack.setItemMeta(meta);
unborn hollow
#

something went wrong hmm

#

the vanilla command "/give @p mace[minecraft:custom_model_data={strings:['bat']}]" gave me the proper item but not spigot

#

checking the data from the spigot generated one says it has 0 strings attached to it

summer scroll
#

What is that even supposed to do lmao, what is bat, is that like a custom texture?

unborn hollow
#

bat is just the identifying string in the resource pack files to render it as a different texture if the item in-game has it

summer scroll
#

Ah interesting

#

Could you send your code again please

unborn hollow
# summer scroll Could you send your code again please 
ItemMeta meta = itemStack.getItemMeta();

List<String> strings = new ArrayList<String>();
strings.add("bat");

var modelData = meta.getCustomModelDataComponent();
modelData.setStrings(List.of("bat"));
meta.setCustomModelDataComponent(modelData);
itemStack.setItemMeta(meta);

event.getPlayer().getInventory().addItem(itemStack);```
summer scroll
#

Looks correct

unborn hollow
#

that's so weird because the game says the item generated has no string apart of its custom model data

#

"Felinkaa has the following entity data: {"minecraft:custom_model_data":{}}"

summer scroll
#

I wonder why getCustomModelDataComponent() is non-null however you can pass null to setCustomModelDataComponent

slender elbow
#

because ItemMeta is a highly flexible system

unborn hollow
#

hopefully i can find a way for it to work this is so frustrating

summer scroll
#

If I pass null it would just return to its original form?

slender elbow
#

no, it'll create a new, empty one

chrome beacon
#

null would just remove it

slender elbow

that's why you also check for hasFooBar

Oh remove it okay

and there's a way to do that:

For example, I have two worlds

one ordinary world

the second one: donate_world

and it is possible to make it so that in donate_world and world, there were separate homes for example in world to work the command /home

and in donate_world the command /dhome

and each command would have its own functionality?

harsh surge

Still got the prob

turbid crown

which one?

i was on bout my GENERIC_MAX_HEALTH not working

i was told 2 update and it still not working

It's just MAX_HEALTH now

harsh surge
#

ohhhhh

turbid crown
chrome beacon
#

You can keep your homes in a map

turbid crown

like, I need the hams to be separate in each world.

like, I'm gonna have donate_world with no wipes.

and the donate_world will be wiped.

I need to make sure that after a vyp, all the hams in the world are deleted.

but in donate_world they don't get deleted.

can this be done with one plugin essentials?

If you're not making a plugin this is the wrong channel

Hi, I'm having a player spectate a blockdisplay that is teleporting with the .setTeleportDuration() method.
During the blockdisplay movement, if it's too quick, the player triggers 'moved too quickly' in the console, is there any way to disable this for the duration the player is spectating the blockdisplay?

Through nms or something?

I'm currently experimenting with text displays to make custom nametags.

Everything works fine, but when using the see through property it makes the nametag very visible through walls. When disabling see through you can't see it through walls at all.

Is there a way to make it so the text displays work just like player nametags, where it becomes transparent when viewed from behind a wall?

Hello. I've seen a claims plugin in the past, that uses particles on the ground to outline an area. It creates like a square perimiter of the area using particles.

Any idea how this is done, other than just recursively creating particles?

it doesnt need to be recursive

#

just loop over the perimeter

#

you can make a lot of optimizations but only doing particles within the players radius and not doing it so fast

also this prepareitemenchantevent gets fired 3 times when you put a item in?

getItemMeta returns a copy

and I believe getPersistentDataContainer does so too

so make sure you've set them correctly

Only meta

btw the enchant event doesnt say item is null only the anvil event

so basically i just need to make sure the item isnt null then it should be fine
