brb

for hub server i mean bungeecord server
i will save this

• globalmoney (special money for all server in bungeecord)
• rank (rank for all server in bungeecord
• last join
• bantime
• mutetime
• isafk

for games in bungeecord

• money
• level

which one am i need cache with hashmap ?
am i need control some data query for hub server ?

[eternal oxide]

you can safely store all this on bungee

nothing is that time specific you could not query bungee as you need

[quaint mantle]

i don't need cache datas in hub server ?

and i need cache money ?

bcs money

all time changing

[eternal oxide]

constantly changing?

[quaint mantle]

This database also makes continuous queries.

[quaint mantle]

money players can change moneys everytime on buy sell pay

[eternal oxide]

for those values I'd not cache anything on the spigot server

[quaint mantle]

The database will always work.

[eternal oxide]

just send/request values/changes to bungee

if they sell something you send the amount of money they gain to bungee

[quaint mantle]

money isnot for bungee

is for server in bungeecord

but globalmoney is for all server i mean all server in bungeecord

[eternal oxide]

if they want to buy something you must already have some UI or something open so you should already know how much money they have.

yes

but they don;t have different money in each server

[quaint mantle]

it will be different on each server

i mean money

but not globalmoney

wait

choco said this

i will find

[eternal oxide]

if its only relevant for a specific server then it shoudl be stored on/by the server

if its global then store on bungee

[quaint mantle]

yes

i save this datas in mysql

instead of constantly changing the money in the database

I should have added hashmap to money

after player on left server i need add money in hashmap to database

[eternal oxide]

the only issue you are going to have with caching values on a server is when switching servers

[cinder abyss]

Hello, how can I make a packet-based entity with ProtocolLib ?

[eternal oxide]

when using bungee and switching servers teh player will join the other server before you have finished processing the disconnect event

[echo basalt]

I got a gist on that

[quaint mantle]

Error occurred while enabling Skyblock v0.2AlphaBuild (Is it up to date?)
java.lang.NullPointerException: null

[icy beacon]

hey there, I've been working on my network with many custom written plugins for a while, and I've recently started questioning whether mysql databases are good for scalability and performance. I'm mostly storing generic player data like locales and per-gamemode stuff, and I only work with loaded caches, so performance is not largely problematic for me, but I'm worried that if the network ever takes off, I might need to learn more about scalability. are there any good resources and comparisons for databases MySQL vs NoSQL and where generally can I learn more detailed and technical information about databases? please provide your trusted resources and links, I'll be happy to get into it tomorrow morning 🙂

[quaint mantle]

oh that is i wasnt think this

[cinder abyss]

full error ?

[quaint mantle]

how do I check for null thing?

[quaint mantle]

rest is error at line 133

[cinder abyss]

thanks

[quaint mantle]

so what u prefer ? wait i will not add my money plugin to bungeecord btw

[cinder abyss]

copy paste the full error

[quaint mantle]

cmon I just got of the pc

fine

[cinder abyss]

all the stacktrace

[quaint mantle]

?paste

[undone axle]

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

[eternal oxide]

for me I'd only cache server specific money. global (bungee) money don't cache, read direct from bungee

[austere cove]

MySQL will most likely suit your needs unless you're talking about an incredibly large playerbase

[icy beacon]

I don't think I'll grow to the sizes even comparable to say hypixel of course, but even so, I'd like to be prepared for the worst case scenario all the time. if you've got any place from where I can learn deeply about databases, I'd be happy to hear that

[hazy parrot]

Actually a lot of people shit so much on mysql (even tho I don't understand hate), calling it awful performance, unreliability etc

[icy beacon]

haha, I've seen the hate yeah, but I don't want to be influenced by it

[quaint mantle]

well, if i create cache hashmap in bungeecord server and if i get globalmoney from hashmap
is it will be a problem ?
that was a last question

[eternal oxide]

no, caching on bungee is great

[quaint mantle]

alright ty

[hazy parrot]

There is even tag in jda ahahag

yes I know 1.8 is 200 years old

but

[cinder abyss]

Hello, I found this code:```java
private void spawnEntity(Location location, Vector vector, EntityType type) {
int entityId = 10000;

PacketContainer packet = new PacketContainer(PacketType.Play.Server.SPAWN_ENTITY);

// Crucial data, do not remove
packet.getIntegers().write(0, entityId);
packet.getUUIDs().write(0, UUID.randomUUID());
packet.getEntityTypeModifier().write(0, type);

packet.getDoubles()
        .write(0, location.getX())
        .write(1, location.getY())
        .write(2, location.getZ());
// -- section end --

// Velocity, remove this code section if you want to default to 0
packet.getIntegers()
        .write(1, convertVelocity(vector.getX()))
        .write(2, convertVelocity(vector.getY()))
        .write(3, convertVelocity(vector.getZ()));
// -- section end --

// Pitch and yaw, remove this code section if you want to default to 0

packet.getIntegers()
        .write(4, (int) (location.getPitch() * 256.0F / 360.0F))
        .write(5, (int) (location.getYaw() * 256.0F / 360.0F));

// -- section end --

// Send the packet to all players
try {
    for(Player player : Bukkit.getOnlinePlayers()) {
        ProtocolLibrary.getProtocolManager().sendServerPacket(player, packet);
    }
} catch (InvocationTargetException e) {
    e.printStackTrace();
}

}```For creating a packet-based entity, but idk what to put into int entityId
Any idea
(I think if I use two times this code with the same entityId, there will be an error

[tender shard]

what's SItem line 483?

[quaint mantle]

meta.setDisplayName(statistics.getRarity().getColor() + specMaterial.getDisplayName(variant));```

[tender shard]

meta is null or statistics is null or statistics.getRarity() is null or specMaterial is null

add some debugging output to figure out which of those is null

probably it's the meta since ItemStack#getItemMeta() is nullable

[cinder abyss]

use System.out.println before this line (best manner)

[echo basalt]

something tells me I wrote this code

[quaint mantle]

could be statistics

  {
            if (material.hasClass())
                material.getStatistics().load();
            return;
        }```

[tender shard]

if you'd be using a recent java version, the stacktrace would contain the name of the variable that's null

[quaint mantle]

what is this platforms ?

[tender shard]

waterfall is the paper version of bungeecord

[quaint mantle]

assert statistics !=null;
        meta.setDisplayName(statistics.getRarity().getColor() + specMaterial.getDisplayName(variant));```

what this do?

[tender shard]

nothing

[cinder abyss]

nooooo

[tender shard]

assertions are disabled by default

[quaint mantle]

hmmm

[cinder abyss]

then, do I need to leave it default ?

[echo basalt]

The entity ID is a number that represents the entity's lifecycle

Like

If you say "Entity abc is 123" in the spawn packet and refer to it as 123 from there on, the client understands what entity you're talking about

And that's pretty much how entities work in the protocol

You just send a spawn packet with a numerical id and then reuse that id in later packets

I like to just start from 50000 and just increment for each new entity

[quaint mantle]

bungeecord projects only for bungee events ?
i mean if i add plugin non bungeecord to bungeecord plugins will work fine ?

[cinder abyss]

okay thanks 😄

[echo basalt]

oh god you have no clue what you're doing

[tender shard]

bungeecord API has nothing to do with spigot API

spigot plugins won't run on bungee at all and vice versa

?jd-bc

[undone axle]

https://ci.md-5.net/job/BungeeCord/ws/api/target/apidocs/index.html

[tender shard]

these are the bungeecord javadocs ^

[gleaming grove]

I had same issue today. To resolve it you should use ItemDisplay instead of BlockDisplay to display blocks. I know that sounds weird, but BlockDisplay has rotation origin at the bottom left block corner (0,0,0) while ItemDisplay origin is at the center point of block/item (0.5,0.5,0.5)

[quaint mantle]

but some plugins works on bungeeand spigot

like luckperms

they using two lib

in project ?

[echo basalt]

That's because they wrote multi-platform code :p

[tender shard]

ItemDisplays show the item, not the block though. one could have just fixed it with a proper translation

[gleaming grove]

they does

[echo basalt]

They just write "generic" code and a bunch of interfaces and at the end make a "platform" for each server type

[tender shard]

pleaaaase use the consumer when spawning entities like that D:

https://blog.jeff-media.com/use-consumers-when-spawning-custom-entities/

[gleaming grove]

good to know

[quaint mantle]

i wanna make api plugin for my other plugins
but my api is for bungeecord
and other plugins non bungeecord this will work fine ?

[river oracle]

does Chunk#getChunkSnapshot forcibly load a chunk given its not loaded already

doesn't look like it probably. Checked CraftBukkit code

[lilac dagger]

i didn't know about item display 😮

they're so cool

[quaint mantle]

Anyone know how imagine fun handles so many entities, (more information past what Matt wrote on his blog)

[shadow gazelle]

How who/what handles so many entities?

[quaint mantle]

Imaginefun, you can google it

[lilac zenith]

Hello, does someone know if there is a way to show a player's 2d face in their screen using a Texture pack and a plugin? I know about negative spacing and such, but idk how to retrieve that player's face to show them in the screen.

[echo basalt]

You need to query mojang's servers

or use happyhud :)

[river oracle]

Okay so I have a little bit of a predicament I kinda am Having a hard trouble wrapping my brain around atm.

Essentially I need a bunch of ChunkSnapshots because I need to scan chunks for specific blocks. Doing this on the main thread would be rather expensive which is why I'm using Chunk Snapshots to search for all instances of these blocks. However you have to take ChunkSnapshots synchronously to my knowledge. So i setup some work distrobution from 7smile7's thread so I can run as many Chunk#getChunkSnapshot calls as possible without lagging the server. On each one of these calls I need to operate on the ChunkSnapshot asynchronously. To do this I added a method to my Worker interface which is called void completed(Object object) essentially its a consumer that executes after the Worker finishes getting the ChunkSnapshot. This approach is pretty flawed and I can shoot holes through it all day. I'm just not sure a better way atm my brain is busted and I haven't really taken any breaks on this

[eternal oxide]

you could push your finished data to a queue and process it in a single thread

[river oracle]

honestly I was thinking of something along the lines, you think after the data is finished I add it to another queue that sends data in for Asynchronous processing

[eternal oxide]

if you are going to be making any changes to a chunk based upon that data you will have to be sync

[river oracle]

I'm only reading data

from the ChunkSnapshot

so everything I do with it can be processed asynchronously once I grab it

[eternal oxide]

what do you do with the end data?

[river oracle]

I push it into my own Databases

[eternal oxide]

then just do as you are. multiple threads running async is not an issue

your system likely has a few thousand running at all times

[river oracle]

my main struggle with this design is thinking of how to funnel all the data back into one BigInteger which eventually happens at the end. like how do I sync all of those asynchronous tasks into one number 🤔. I mean pushing the finished data into the Queue makes sense to me, but how am I supposed to know when every single ChunkSnapshot has finished processing in the queue

[eternal oxide]

count them

you can see how many snapshot you took

[river oracle]

yk sometimes you overlook the simple things lol

[eternal oxide]

you shoudl have an equal number of resultsd

[river oracle]

yeah that's a completely valid point I have the beginning number of chunks I need processed just keep holding the task until they all finish

thanks 😆 to think my issue had such a simple solution well its clear as day now

I tend to overthink these things huh

[eternal oxide]

I've written some terrible code in the past, many many lines.

only to replace it with a handful the next day

[ivory sleet]

same

extends to every dev

[echo basalt]

yeah p much

I've written shitty code

now it's all enterprise

[quaint mantle]

am i need connection.close and statement.close methods in hikaricp ?

[eternal oxide]

wrap in a try with resources and you won't

[quaint mantle]

What is the equal of "long" in sql?

i save discord user id with number

[eternal oxide]

INT or BIGINT, depending

https://dev.mysql.com/doc/refman/8.0/en/integer-types.html

[quaint mantle]

ty

what is float in mysql workbench ?

[echo basalt]

are you blind

[wet breach]

its another number just like in Java

[quaint mantle]

i can't saw in docs

[wet breach]

Double is equivalent to float, just double precision or double wide

[quaint mantle]

float is like double ?

like this

5.1 ?

[lunar wigeon]

yes, it is floating point number. You can do 3.141f

[wet breach]

double is 2 floats. Basically its the long variant of floats

[quaint mantle]

omg

i thought the float was a variable
above int and long

._.

[eternal oxide]

int and long are whole numbers. No decimal point

float and double are floating point numbers

[quaint mantle]

i was think float is number 😄 not decimal point

mb

[echo basalt]

Is there no Configuration#getValues in bungee? I might need to do something recursive

[sullen marlin]

discord float ☠️

[echo basalt]

Mhm there's also no Configuration#getName

I blame you, md

[sullen marlin]

Idk open a feature request

[echo basalt]

can't bother lmao it's much easier to write those 15 extra lines

[sullen marlin]

Wtf is getName anyway

[young knoll]

This is why the api never improves

[echo basalt]

it returns the name of the section

[young knoll]

😔

[echo basalt]

Or empty if it's a fileconfiguration

[lunar wigeon]

there is ConfigurationSection#getName

[echo basalt]

That's bukkit

joe:
  mama: "Hah! GOTEM!"

ConfigurationSection section = config.getConfigurationSection("joe");
assert section.getName().equals("joe");

I use getName for my multi-platform config section thing

[wet breach]

seems a bit redundant to have a getName?

[echo basalt]

It's useful

[wet breach]

couldn't you just extract that from the path

[echo basalt]

In context, yeah

So what I'm doing in my bridge class is just add a name param

Mhm there's no saveResource method on bungee

funkjy

[orchid gazelle]

I have it too, it's great. I really enjoyed the bait of them with the hair on one of the first pages

[quaint mantle]

someone check my codes to tell my mistakes
hikaricp class
https://paste.md-5.net/zuzijiqupe.java
and this dbmanager sry i can't paste this to md5

package me.vasir.manacore.database;

import org.bukkit.ChatColor;

import java.sql.SQLException;
import java.sql.Statement;

import static org.bukkit.Bukkit.getLogger;

        try (Statement statement = HikariCP.getConnection().createStatement()){
            String sql = "CREATE TABLE IF NOT EXISTS global(uuid varchar(36) primary key, username varchar(16), discord int, crystals int, boost boolean, bantime int, mutetime int)";
            getLogger().info(ChatColor.GREEN + "Connected database");
            statement.execute(sql);
        }
        catch (SQLException ex){
            getLogger().info(ChatColor.RED + "There was an error in database -> ");
            ex.printStackTrace();
        }

    }
}

my sql code is right ?

for discordid do i int ? or bigint ?

[hazy parrot]

Discord ID go far more then 4000000000

[compact haven]

bigint

[quaint mantle]

for unixtime ?

[compact haven]

anything LONG in java -> BIGINT

[echo basalt]

bruh is there seriously no way to disable a bungee plugin

[eternal oxide]

unixtime is also long (ignoring other time data types) so bigint too

[quaint mantle]

ty

[quaint mantle]

yes i can't use

where can i see hikariconfig default properties ?

i mean maxidletime

[eternal oxide]

you don;t call close ever using hikari

try with and thats it

[hazy parrot]

Also this looks a bit like static abuse, search for imillusion search index static in this channel, it's pretty well explained

.

[quaint mantle]

but statics is cooll 😄

i only write class name after dot method or object

😄

[young knoll]

With Hikari you are meant to close connections

And presumably statements too

[quaint mantle]

wdym ?

am i n eed ?

hikari don't close auto ?

[hard socket]

how can I stop particles from going crazy I used flame particle btw

[eternal oxide]

add a speed

[young knoll]

Hikari uses a special connection object where the close method returns it to the pool

Rather than actually closing it

[hard socket]

speed?

[eternal oxide]

in the spawn

use the method which accepts a speed value

[hazy parrot]

Yeah it sure is, but read whole post

[hard socket]

ok

[calm pasture]

yo does anyone know bungeecord and how to make it so whenever u get kicked from a sub server it sends u to like the lobby or smth idk how to do it

[quaint mantle]

is that right ?

am i need do this ?

[sullen marlin]

There's plugins, hubkick, movemenow

Probably lots more

[young knoll]

No

[calm pasture]

i've tried movemnow, didnt work will try hubkick tho.

[quaint mantle]

but someone was write

[young knoll]

Your connection is already closed by the try-with-resources

[quaint mantle]

ah

closing statement btw ?

[young knoll]

Actually you should make the connection a variable inside try with resources

[quaint mantle]

wdym

😢

[eternal oxide]

Statement statement = connection...;) { /* code */```

[quaint mantle]

I do one thing and something else pops up.

[calm pasture]

hubkick doesn't work... do you know how to set it up? do i put the plugin in my bungeecord server or sub servers?

[eternal oxide]

never call close yourself, the try with resources does it all for you

[quaint mantle]

i was used this

        return ds.getConnection();
    }``` in hikaricp

so other way better

[eternal oxide]

no thats fine

[quaint mantle]

but at this method

i can't close connection

[eternal oxide]

How many times are we goign to type, you do not close the connection

[eternal oxide]

NEVER call .close()

the try with resources does it for you

putting it in try (...) makes it auto close if it can when finished

[quaint mantle]

coll consufed me

[eternal oxide]

he was saying to do as I showed above

get connection and statement in the ()

two variables it will try to close on both

the id is NOT in the table already, the table is brand new and ive deleted it and remade it

[river oracle]

duplicate entry you need to update if the entry already exists

[dry forum]

the id is NOT in the table already, the table is brand new and ive deleted it and remade it

[river oracle]

the error says otherwise there wouldn't be a duplicate entry error if the key wasn't in the table

my guess is you could be accidently running the code for the ID twice or you just aren't actually deleting the database

[dry forum]

that is 100% not in the database, ive tried deleteing the entire database and remaking it, same error

and its not being run twice so idk

[river oracle]

duplicate entries only happen if theirs a duplicate entry so you have falty logic somewhere

couldn't say more without more code. This section itself seems fine as their are no loops

[eternal oxide]

my guess, you are calling the method twice

You are calling it twice or it's already in teh database, those are your only options

i use hikaricp to read/write from code and mysql workbench if i need to check content

[cedar brook]

does anyone know if it's possible to embed my plugin's download count (or even the whole information panel) from spigotMC onto my website? 🤔

[inner mulch]

mysql workbench for servers?

[remote swallow]

if its cli i just open the db and run the commands to show data

[river oracle]

Is there anyway to get an EntityType of a spawner asynchronously or am I about to put myself through nested asynchronous synchronous multithreaded hell

[sullen marlin]

if you have the blockstate you can do whatever async

but you cant get a blockstate async

[river oracle]

🥲 ChunkSnapshots only get you so far

[sullen marlin]

your internet is broke and cant reach mojangs servers

[river oracle]

what version you tryna get

[sullen marlin]

if you want the api, its all on nexus

[remote swallow]

?maven

[undone axle]

[river oracle]

What's the difference between BlockData and BlockState I feel like CreatureSpawner should be in BlockData but its in BlockState

ahhh ic

nothing but the good old docs yk I was hoping this wouldn't be painful

[young knoll]

State contains the NBT data of block entities

Data contains the states

Because confusion

[river oracle]

no doesn't State Contain the Data and Data doesn't contain anything

[young knoll]

Well for a spawner

There are no states so yeah

[river oracle]

you can only create empty block states with BlockData

[river oracle]

I wonder do you think it'd be easier to read the raw NBT asynchronously with NMS or would that break to

[young knoll]

/shrug

[remote swallow]

epic /shrug fail

[young knoll]

I don’t know if you can read the BlockEntity from the world async

Which contains the NBT data

[river oracle]

so I'd be forced to sync either way huh

well pain

time to start over again at square one

[young knoll]

Why not pass all the states along with the snapshot to your async stuffs

[river oracle]

that would be an unbelievably expensive operation

[young knoll]

How so

[river oracle]

how can I realistcally pass the states of thousands of blocks without causing lag

I need to do work dist on the block states as I'm doing with ChunkSnapshots atm

[eternal oxide]

you get them from teh snapshot. lag shoudl not be an issue

[river oracle]

you can only get BlockData from a snapshot

[eternal oxide]

you don;t use teh snapshot to read chunk data

[river oracle]

not BlockState

[young knoll]

You can easily get all the tile entities with Chunk#getTileEntities

[river oracle]

true didn't think about that

[river oracle]

can you safely read chunk data async otherwise?

I thought that was kinda the whole point

I frozen in time capture of the data in the chunk that ensures ThreadSafety

[eternal oxide]

Why do you want to read from teh chunk and not the snapshot?

[river oracle]

I would prefer to only read from the snapshot but the snapshot isn't able to get BlockStates

[eternal oxide]

correct, it gets BlockData

[river oracle]

unfortauntely blockdata is useless for my current issue which is getting spawner type

which is stored in the BlockState

since spawners are a TileEntity iirc

[eternal oxide]

ah yes, you can only get a default BlockState

[river oracle]

so if a Block is a spawner I'll need to queue a task on the main thread and retrieve the block state for the continual operation

[young knoll]

Yeah just grab all the spawners before hand and pass them along with the chunk snapshot

[eternal oxide]

there will not be many TileEntities, you could get them and pass at teh same time you do the snapshot

[river oracle]

do you think that won't be an issue. I mean I feel like it'd be more graceful to go with my solution. Let's say I have to scan 1,000 chunks (idk how big towns can get in towny), but wouldn't passinng through all those tile entities be a waste if I won't use 90% of them most of the time I guess I could make some data class and have my mainthread task scan for spawners as well 🤔 , but idk how future proof that is if I start considering other tile entities as well. I'm open for feedback I'm kinda new to these levels of asynchronous logic lol

your main class

put the path to it

[eternal oxide]

you are scanning claimed chunks to do?

[river oracle]

just get a count of specific block types

[eternal oxide]

is there a reason?

[river oracle]

kinda like /is value in a lot of Skyblock plugins if yk what I'm talking about

[eternal oxide]

no clue

[young knoll]

You could also make your own snapshot that contains spawner data

[river oracle]

it counts up all of the "value blocks" you have on your island and adds them to a total score and you're placed on a leaderboard based on that

I wonder if I could actually use NBT here instead 🤔 though I'd have to scan initially anyways

[eternal oxide]

Well I'd suggest just grabbing all the tile entities you need and passing with the chunk. It's really simple ```java
public List<Chest> getAllChests(Chunk chunk) {

    return Arrays.stream(chunk.getTileEntities()).filter(Chest.class::isInstance).map(Chest.class::cast).collect(Collectors.toList()); //newer Java .toList();
}```

[river oracle]

yeah fuckit I'll do it like that 😮‍💨 its ashame I have to go back to square one here with a lot of my logic though I completely overlooked that ChunkSnapshots can only get BlockData

thanks for all your help

[remote swallow]

your main would be main: com.mcorsen.main.MainClass

ur missing a java and a main class

do you use maven

k, this is what the setups should look like

you should have one

are you not using an ide

@young knoll this is ur issue now

maven or gradle usually helps

[young knoll]

You don’t have a main/java when you aren’t using maven or gradle

Okay

[quaint mantle]

can't you just track whenever they place a block and add that to the island data ?

store like a Map<Material, Int> // int representing the amount of that type

[young knoll]

Decent until a block gets placed by some other means

(Or removed)

[river oracle]

Yeah I was about to think about that but it gets flawed asf quickly

[lavish hemlock]

To what degree does Mojang's anti-distribution licensing apply? If I were to maintain a non-public repository containing decompiled code, would that be against their policies?

Obviously publicly distributing a compiled jar is bad, but if one can privately "distribute" a compiled jar (from one of their servers to the next), should the same apply for code?

[manic crown]

I made it now like this, but I do have the shadow there, is there a way to remove the shadow somehow?

[lost matrix]

Probably with a core shader

[manic crown]

uhhhmmm XD

[manic crown]

like this?
https://github.com/McTsts/mc-core-shaders/blob/main/remove text shadow/rendertype_text.fsh

[lost matrix]

Yes, now you just need to set the opacity of your text that should not have any shadows to 254 instead of the normal 255

[manic crown]

you mean the white dots?

[lost matrix]

Yes

The text, not the image (if i read this correctly)

[sweet sonnet]

What exception is thrown if reloadConfig(); fails?

[lost matrix]

Depends on what went wrong

[sweet sonnet]

So this should be fine?

try {
    SnowReports.getInstance().reloadConfig();
    sender.sendMessage("§aConfig reloaded!");
} catch (Exception e){
    sender.sendMessage("§cConfig reload failed! Check console for errors.");
    Bukkit.getLogger().warning(e.toString());
}

[lost matrix]

But there are not too many cases where it throws an exception.
One could be InvalidConfigurationException if the user just wipes the yml file with empty text.

[lost matrix]

Meh, not really. I would not catch an exception here.
Just let it throw.

Unless you need to handle exceptions in a special way here

This line will create potentially very confusing log messages

Bukkit.getLogger().warning(e.toString());

[manic crown]

do the shaders need optifine?

[lost matrix]

No they are core shaders

[manic crown]

okay

can I specify a font for the shader?

[opaque scarab]

What packet tells the client health of the mount being ridden?

[lost matrix]

I would assume that the client gets this information from the metadata packet. No reason to
send additional packets if the client already knows the health of the mob.

[lavish hemlock]

And actually to elaborate, this repository would technically be accessed by multiple people.

[manic crown]

I can not manage it to work because the colors are sometimes lighter sometimes darker I think, but that far, thank you
But it seems like I am not the only one:
https://user-images.githubusercontent.com/32773961/202585468-50f7663d-9df2-4ff1-b8ee-7beab1140783.png

[opaque scarab]

If I set the health to 0, can the entity still appear alive to the client? I want to remove the health info.

[lost matrix]

Add credentials to the access. With multiple people its kind of a gray area.

[lavish hemlock]

Okay so to reiterate, I can store decompiled Mojang server code in a private repository but it's a gray area so I should try and protect it?

Sorry for being repetitive, it's just an important topic, of course.

[buoyant viper]

im fairly certain this is a yesn't

as long as ur not distributing it u should be in the clear

[lavish hemlock]

Alright.

thats for the animation though

the ability to pull mobs

judging the fact you run these 2 methods every tick forever, it doesnt surprise me why its crashing

[lost matrix]

Ok but why do you clone the location and then add 0 to it?

[quaint mantle]

hmm

[lost matrix]

You should not create a Runnable for every yaw. Create one Runnable that handles the whole circle.

[lost matrix]

He has a cancel safeguard for the runnable

[remote swallow]

oh i didnt see the cancel

[quaint mantle]

but is the issue with the cacheLocation or

the bukkit timer

[lost matrix]

Im seeing quite a few things that can crash the server or seriously tank the performance here.

The whole loops logic makes little sense to me

            System.out.println("d1.2");
            Location cacheLocation = sloc.getBlock().getLocation();
            for (int y = cacheLocation.getBlockY(); y > 0; ) {
                if (cacheLocation.add(0.0D, 1.0D, 0.0D).getBlock().getType() != Material.AIR) {
                    y++;
                    continue;
                }
                for (int i = 0; i < 40; i++)
                    a(cacheLocation.clone().add(0.0D, 0.0D, 0.0D), (i * 12));
                pullingMobsTo(cacheLocation.clone().add(0.0D, 0.0D, 0.0D));
            }

[quaint mantle]

I mean I added the d1.1 thing to debug
so only d1.1 is executed and the server then shits itself

[lost matrix]

Let me show you how i would tackle this

[lost matrix]

Ok you need to explain to me what you are trying to achieve in this loop. The more i look at it the more scuffed it gets.

[quaint mantle]

the cachelocation right?

[lost matrix]

Explain to me in plain text what "startGyrowandAbility" should achieve.

[quaint mantle]

oh right

it should do something like this

https://www.youtube.com/watch?v=37_R7ahD6A4

the animation and pulling the mobs into the thing

[lost matrix]

Ok. So the first thing you need is the block the player is currently looking at.
This is done through a ray trace because the distance to the block will fluctuate greatly.

You can not just assume 10 as a gixed distance.

You are using 1.8 so ray tracing is not supported by spigot (The version is a decade old soon, why tf you use it at all)

[quaint mantle]

do I try cancelling the event

with taskID

bukkit.getSchedsaiosdio().

[lost matrix]

You are taking a step back and breaking down this ability into smaller pieces.
The first problem you need to solve:

• How do i get the Block, a player is currently looking at.

After that we can continue with how to implement the effect

Do you have BlockIterators in 1.8 already?

Fk i hate this old garbage version. Why do people insist in using it?

[lost matrix]

Tell me when you solved the first problem. Afterwards ill explain to you how to properly create the effect
without any lag or crashes.

Hi, on spawner break i need to check if it is registered on the db.

What i do?

Load all data at start?
Just load spawner at chunkload?
Request the db at spawner break?

[tender shard]

i'd just use CustomBlockData to store your data in PDC

?blockpdc

[undone axle]

Learn about CustomBlockData here:
https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[sterile breach]

What is PDC?

[tender shard]

PersistentDataContainer

https://blog.jeff-media.com/persistent-data-container-the-better-alternative-to-nbt-tags/

[sterile breach]

Yes but i need to store it il db for other interaction when my bloc hot breaked

[tender shard]

then I'd just use a Set<Location> on startup

[desert tinsel]

but how do I get who crafts the item? Does that work: java Player p = (Player) e.getViewers().get(0);

[tender shard]

however I don't see any reason why you couldn't use the PDC

you could also listen to chunkloadevent, then get a set of all blocks with custom PDC and add the spawners to your set then

[sterile breach]

Yeah can is a good idea

Byr i want know, excepted PDC. How to do?

[torn shuttle]

if my laptop keeps telling me that keeping my screen on hight brightness increases carbon emissions I'm going to have a conniption

            PlayerInventory playerInventory = player.getInventory();
            player.sendMessage(playerInventory.getItemInMainHand().getType().toString());
        }

        return false;
    }```

[tender shard]

you didnt set an api-version in plugin.yml and hence have legacy material support enabled

set an api-version in plugin.yml

no

Hi, on spawner break i need to check if it is registered on the db.

What i do?

Load all data at start?
Just load spawner at chunkload?
Request the db at spawner break?

[tender shard]

I already answered this exact question

[sterile breach]

yes but as I am still learning spigot, I preferred to avoid going through your system.

[vast ledge]

@tender shard What was ur suggestion?

Delor

[sterile breach]

PersistentDataContainer

[vast ledge]

What are you tring to make

Yea

Persistentdatacontainer

would be the best approach

[tender shard]

CustomBlockData or to just load a Set<Location> from their DB on startup

[vast ledge]

i a green with mfnalex here

agree**

Another suggestion would be creating an Array wouldnt it?

[sterile breach]

my plugin is simple. When a palyer palce a spawner. The spawner got protected (if the spawner got break, the player can get it in a gui)

so, on spawner break i need to check

yes at the beginning I loaded the whole db in an array at the start

[vast ledge]

@tender shard Would there bea anything wrong with writing an array with the blocks to the Database, and on startup reading the Locations?

[sterile breach]

ah i can stock the owner name i the nbt?

[vast ledge]

You cant touch NBT

You would need nms to do that

[sterile breach]

well the problem is that if there are 1500, I can't load everything when I start and unload when I stop

[vast ledge]

What you could do, is create a custom Object, that stores block Locations, The player that placed it

[sterile breach]

I mean, in the data of the block like the nbt

[tender shard]

PersistentDataContainer basically is NBT but you said you didnt wanna use it

[vast ledge]

You could check if a player places the block then check if the DB contians the coords

[tender shard]

I can only repeat myself: just use CustomBlockData

?blockpdc

[undone axle]

Learn about CustomBlockData here:
https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[sterile breach]

I misunderstood what it was I was looking at.

[vast ledge]

Yea, that would be the smartest

[vast ledge]

It is basically a "containter" that saves data to a certain block, even when the server restarts

[sterile breach]

ok i will try then

if i palce it

on break i can get the owner name for exemple?

[lost matrix]

I had an article about working with data.
Data is transfered from the in rest state (DB, File, etc)
to its in use state, when the session of the data starts.
It is written back to its in rest state when its session ends.
Some examples for sessions are:

Player session

• Starts when player connects to server
• Stops when player quits

Chunk session

• Starts when chunk us loaded into memory
• Stops when chunk is being unloaded

World session

• Starts when a world is loaded
• Stops when a world us unloaded

So in your case i would load the data when the Block (and subsequently its chunk) is loaded.
And saved back when its unloaded.

[sterile breach]

oups

[sterile breach]

you want say
when the chunk's block is loaded?

[lost matrix]

If you want to use the PDC of your TileEntity, the PDC of the Chunk or a Database
is secondary in my opinion.

[lost matrix]

A chunk loads with all its blocks and tilestates. Thats what i mean.

Which method you use also depends on the size of your data and how many instance you expect in one chunk.
Last thing you want is extra data significantly slowing down your chunk loading. This could occur with the PDC of
chunks or Blocks.

[sterile breach]

the problem is that with dozens of players connected, it will sometimes load several dozen chunks per second.

Or in the onChunk load, I loop all the chunk's blocks in async and if there's a spawner, I request? because if I request the db for each new chunk, it's too much.

i just need to store the owner and the location but with pdc i don't need location because the block is placed

[lost matrix]

You should never loop through all blocks.
Get your X and Y of the chunk and incorporate that for your DB accesses.

Why do you need a DB if you store half of your data in the PDC anyways?

Or vice versa.

[sterile breach]

yes, but in this case I have to query the db every time a new chunk is loaded? As I was saying, with 10 players, that would mean several dozen queries per second.

[lost matrix]

Why bother with the PDC if you store everything in a DB.

[sterile breach]

because then I need access to its data so that players know where their spawners are placed.

[lost matrix]

I dont see an issue here. Those queries will take micros (if the DB is on the same machine).
And i sure hope you do them from a different thread.

[sterile breach]

yes in async

so let's say I have 10 chunks loaded per second, that's 60 requests per minute, isn't that a problem?

[lost matrix]

Then create a table with chunkX and chunkY as two primary indicies

[sterile breach]

no in my db

euh

what i say

[sterile breach]

an other table ?

[lost matrix]

And a proper database can handle thousands of requeuests per second

[sterile breach]

ah okay I just learned it.

[lilac dagger]

cache where possible

[sterile breach]

I thought about it

[lilac dagger]

so you don't do db request for some frequent stuff

[lost matrix]

You can always batch request the chunks over the last N seconds. This way you dont have to
send too many requests.

[lilac dagger]

me.mcorsen.main.main

[sterile breach]

how do I go about it?

[lost matrix]

[icy beacon]

hey, i'm implementing a verification system for linking discord to minecraft. it's fine to not use a database if i do not care about losing the codes on restart, right? they only last 15 minutes and i just want to use an ExpiringMap and not bother working with yet another table

[sterile breach]

so it's better to use onchunkload rather than pdc?

[lost matrix]

You simply wait N seconds and then create a batch request of all chunks loaded in those N seconds.

[sterile breach]

ah yes

[lost matrix]

Never said that. I asked you why you want this data in a database in the first place.

[remote swallow]

just store the code in a hashmap and with an expires instant and u'll probably be fine

[sterile breach]

ah okay

[icy beacon]

yeah i want to do that too

[remote swallow]

just make sure you setup the linking mc creates the code and discord recieves it

[icy beacon]

i wanna use the https://github.com/jhalterman/expiringmap though

it's very handy

used it a couple times

[remote swallow]

looks useful

[icy beacon]

yup 😛

[remote swallow]

this is cool too

[icy beacon]

yeah i used it in my previous project and it was really convenient i wanna do it again

[lilac dagger]

is it thread safe?

[lost matrix]

Caffeine?

[remote swallow]

this

[icy beacon]

actually have not looked into that, but there's probably info about that in the docs

[remote swallow]

it says its thread safe

[icy beacon]

yes

[lilac dagger]

otherwise is not that fancy

[lost matrix]

Use caffeine instead

[icy beacon]

A high performance, low-overhead, zero dependency, thread-safe ConcurrentMap implementation that expires entries. Features include:

[icy beacon]

what's that?

[remote swallow]

caching library

[lost matrix]

https://www.baeldung.com/java-caching-caffeine

[sterile breach]

and which paroche would you finally recommend? (you know better than I do). But storing the owner in the pdc would make it possible to retrieve it when the sapwner is broken and send it to the db (or cache) and thus avoid massive chunk loading. This seems more optimized to me.

[lost matrix]

LoadingCache<String, DataObject> cache = Caffeine.newBuilder()
  .maximumSize(100)
  .expireAfterWrite(1, TimeUnit.MINUTES)
  .build(k -> DataObject.get("Data for " + k));

Example

[icy beacon]

hm, that looks handy too

alright, i'll use this

[lost matrix]

A cache that requests data if its not in the local map

[lilac dagger]

wait builder? is it immutable?

[sterile breach]

it's a kind of hashmap but you can program automatic evactuation

[lost matrix]

You can always evict entries but never live modify its content.

[icy beacon]

it seems like you can make it mutable

[lost matrix]

Not for loading caches

Just the normal ones iirc

[icy beacon]

alrighty, i'll just try to start, if i'll be having problems i'll consult you 🙂

[lilac dagger]

for caching it's pretty good

[sterile breach]

and which paroche would you finally recommend? (you know better than I do). But storing the owner in the pdc would make it possible to retrieve it when the sapwner is broken and send it to the db (or cache) and thus avoid massive chunk loading. This seems more optimized to me.

[remote swallow]

if the spawner is being broken, the chunk has to be loaded doesnt it?

[lost matrix]

You should decide now.
Store the data completely in the PDC
Store the data completely in a Database

No splitting.
And you should have a good reason for a Database because this will make
the system significantly more complex to implement.

[lilac dagger]

you can hold a reference in the db and store the data in pdc

[sterile breach]

the player must be able to access the list of his spawners placed with their coordinates etc... when a command is needed to open a gui.
My idea was to store everything in the db. Just use the pdc on the placed sapwners so you don't have to check with the db if this sapwner has an owner. But otherwise I can just make an async request to the db when a sapwner is broken.

[ivory sleet]

Pdc is fine

I mean if u wanna make a fkn data analysis or sth, good luck pdc trolled you, else its viable

[golden wren]

i’ve got a bounty command that checks if the player has enough money in their account and if they do it’ll remove a given amount via withdrawPlayer(). if the player spams this command, it just stops taking the money out, meaning that players can glitch money into existence. what can i do to fix this? i’m using the vault API with essentials economy - both latest versions.

[tall dragon]

you could add a cooldown to the command

theres no reason for players to spam this command

[golden wren]

yeah that’s fair

is it just vault stopping it from repeatedly executing the same action then?

[tall dragon]

honestly woulnt be able to tell without directly looking at the code

could be a number of things

[golden wren]

yeah of course

alright i’ll just add a 5sec cool-down, thank you lol

[tall dragon]

[icy beacon]

1. you have not registered your command

2. next time please send code walls with a pastebin like ?paste

np

[eternal oxide]

?codeblock

[undone axle]

You can use the discord code block format to display code or just text in a more pleasing way:
```java
public class MyPlugin extends JavaPlugin {
@Override
public void onEnable() {

}

}```
Becomes:

public class MyPlugin extends JavaPlugin {
    @Override
    public void onEnable() {

    }
}```

[icy beacon]

yeah but it's for shorter codes

if it's a text wall there's no need to block the entire channel with it

just use a pastebin

[eternal oxide]

yep

[sterile breach]

I was going to combine the 2

if i palce a block, on break i can get the pdc?

[undone axle]

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

[shadow night]

When the player crafts something, can I somehow leave a certain item in the crafting slot? Like crafting with buckets

You have set the executor of the command to be the plugin (this)

You need to set it to be the class of the command which has to implement CommandExecutor iirc

It's spigot lol

They only deprecate, they never delete or rename

With what

You need to have the command in your plugin.yml, but you also need to have a command class and register it

[echo basalt]

There is but it's a bit advanced

Relies on reflections

[shadow night]

All I know is how you would do it usually

[sullen marlin]

Surprised there isn't a method for this, although I'm not sure if it only applies to complex recipes. Open a feature request, could be pretty easy

[shadow night]

What the heck is a feature request

[sullen marlin]

?jira

[undone axle]

https://hub.spigotmc.org/jira/secure/Dashboard.jspa

[sullen marlin]

[sterile breach]

Hi, if i understand, PDC is for items. And TitleState for placed blocks?

[echo basalt]

?blockpdc

[undone axle]

Learn about CustomBlockData here:
https://www.spigotmc.org/threads/custom-block-data-persistentdatacontainer-for-blocks.512422/

[echo basalt]

PDC is just a general container that's present in

• Entities
• Chunks
• Items

But projects have been made for blocks as well

[buoyant viper]

then update them

[sterile breach]

what is the differences betwwen this libs and jusste TitleState?

[echo basalt]

TileState is specific to tile entities and doesn't apply to all blocks

It is also only specific for managing that block's data instead of serving as a container for plugins only

A tile state, for example, is a furnace, where it manages burn time and its inventory slots

While with PDC it's basically just a fancy map that's saved in file

[austere cove]

Is there any way to force run all pending tasks for a given plugin

[echo basalt]

uhh

Don't think so

Unless you make your own scheduler

[austere cove]

what a headache

[echo basalt]

¯_(ツ)_/¯

I've been writing multi-platform code lately and now I understand why worldedit has their own class for everything

it's a headache

[icy beacon]

why?

[austere cove]

Suppose I do some db stuff in an async task, and the server shuts/disables my plugin before the task ran, then it will just get cancelled

[icy beacon]

ah

[austere cove]

potentially dropping data

its an edge case but still

[echo basalt]

Easy fix then

For DB stuff just use completablefutures

And put each future in a map/list/whatever

When they complete or give an exception, remove them from the collection

[quaint mantle]

is there a way to register permissions in code (so that it will show up on permission managers like LP)

[echo basalt]

And make a flush method that returns an allOf of the futures, and join it onDisable

[austere cove]

if you define them in plugin.yml they will show up too afaik

[echo basalt]

https://github.com/IllusionTheDev/SkyblockCore/blob/2.0/SkyblockCore-Common/src/main/java/me/illusion/skyblockcore/common/database/cache/redis/RedisSkyblockCache.java

[icy beacon]

Bukkit.getPluginManager().addPermission

[echo basalt]

LP does something funky with permissions

[icy beacon]

it'll show there

[quaint mantle]

I want to import it from a config file

[icy beacon]

i tried

[quaint mantle]

ty ill try it out

[echo basalt]

It has a weird injector thing that every time you call hasPermission it adds it to the possible permissions list

[icy beacon]

Bukkit.getPluginManager().addPermission(Permission("ab.cd", PermissionDefault.FALSE)) off the top of my head

[quaint mantle]

hmm alr

[icy beacon]

when i registered perms like this, they showed in tab-complete for lp

[chrome beacon]

Just don't create a new permission object every time you try and use it

Since creating one should register it

[lost matrix]

I would use my own executor service for stuff like this.
This way you can just call shutdown on it and await execution.

[austere cove]

oh ffs then I have to rewrite so much stuff

[echo basalt]

average concurrency moment

[lost matrix]

Why? This sounds like a design problem. Switching from my own scheduler to
the bukkit one would take me maybe 10mins reimplementing 3 methods with 5 lines or so each...

[echo basalt]

smile still hasn't realized he's a 10x developer

[lost matrix]

Those two

[austere cove]

because currently by data abstraction by design has blocking methods, which I purposely call using async tasks in commands n stuff

[echo basalt]

lmao yeah you're screwed

[lost matrix]

oof

[austere cove]

time for non blocking callback hell ig

[echo basalt]

I should just write yet another guide about how IO should just use futures and not blocking methods

so you can properly join stuff

[lost matrix]

Come to the dark side

[echo basalt]

Dark side

[sullen marlin]

I don't think you need to

You can just send a runnable into the executorservice

Exactly same as runAsync

[echo basalt]

J̴̎͊O̴͑̒I̴͛̑N̷͑́ ̷̿̚U̴̠̎Ś̵

[lost matrix]

If he uses Runnables and not an anonymous or concrete implementation of BukkitRunnable
with some internal cancel() logic then true. He can just pass the runnable to an executor instead
of the BukkitScheduler

So might not be so bad after all

[echo basalt]

le big CTRL + Shift + R

with some regex

and the need to adjust every single number from ticks to ms

[austere cove]

yea it's just runnables atm, but I'm contemplating life choices rn

[icy beacon]

take a break for like an hour, get refactoring when your head is more fresh

coding well is cool but having stable mental health is cooler

i have neither

[austere cove]

coding is my escape, i dont want to go back to reality 👀

[icy beacon]

same 😭

welp then

[echo basalt]

Yo smile I have a minor question

So I made this crappy matchmaking thing for my skyblock core

But I'm not a fan of how I have to do a big query to get all the server data I need for the matchmaking to be accurate

And I feel like it can fill up the ram and be a point of failure

Any better way to do this without relying on a microservice?

I don't think it's going to be that bad

But I'm still not a fan

the big query

[cedar brook]

does anyone know if there's an api for the website? or some way to get the plugin information (specifically the downloads) from the site? 🤔

[icy beacon]

spiget? https://spiget.org/

[pseudo hazel]

spaget

[cedar brook]

thank you 🤩

[icy beacon]

np

[pseudo hazel]

lol

[sterile breach]

I have an other idea on spawner break i just made a request to the db if the spawner is registerded directly ?

[quaint mantle]

i got this error why ?
https://paste.md-5.net/waxiyahejo.sql

[pseudo hazel]

why do you wanna use a db in the first place

[vast ledge]

cross server maybe?

[icy beacon]

?nocode but seems like you're inserting a duplicate value where it's not allowed

[undone axle]

It’s hard to answer a programming question without code
Oh no! You ran into a problem. But no worries, people are willing to help, but first they need to see your code. This is because otherwise, they would be providing help based on guesses instead of concrete knowledge. Whether it be a compile error, runtime error, or an unexpected output, I'm sure that if you were to provide code, you'd receive a quick solution.

[tender shard]

because you can't have duplicate primary keys

[pseudo hazel]

show query

[vast ledge]

You could just get the PDC of the block and check if it has the boolean protected?

[lost matrix]

Im not 100% sure i understand why you need matchmaking for skyblock.
But you probably dont need this map to be a concurrent map.

For your problem: This is a common problem because you have no master server.
Describe to me what the matchmaking is for.

[quaint mantle]

i check

[echo basalt]

This skyblock plugin works as a sort of network, the "matchmaking" part would be for load balancing, to decide what server should be responsible for loading the player's island.

There's no singular server responsible for everyone, just a bunch of instances that load and unload island on demand

[lost matrix]

Load balancing is done on the proxy

[echo basalt]

Correct

I'm just afraid that fetching all the loaded island ids from redis is a bottleneck in scalability

[cedar brook]

ohhhh wow 🤤

I can do sooooooooo much more than i initially though i could with this api for my portfolio website 👀

[lost matrix]

Then your approach sounds fine to me.
Just let all server subscribe to a redis topic and
post their data if the proxy requests it.

But there is a simpler solution: The proxy knows every
connect and disconnect. He can simply keep track of
that locally and apply its load balancing strategy accordingly.

[echo basalt]

Yeah but what if there are multiple proxies

[icy beacon]

haha, good for you 🙂

[echo basalt]

You're telling me that instead of doing a request to get all the island ids, I should have it at all time?

That'd just constantly take up RAM

[lost matrix]

Maybe 2 MB for a thousand players

[echo basalt]

Well

So would my approach

But I don't see any skyblock network with a million players so this isn't a concern yet

[lost matrix]

• the overhead of requesting everything

[echo basalt]

That's like 2ms on redis

maybe 3ms on mongo or whatever

[lost matrix]

Wait... you mean... all ids of all player, ever?

[echo basalt]

No

[lost matrix]

Not the currently loaded ids?

[echo basalt]

Just the ids of the loaded islands

[lost matrix]

Keep that sht in memory

[echo basalt]

Eh

Rather have redis

[lost matrix]

Your approach is fine

[echo basalt]

Or memcached

[lost matrix]

Thats in memory

[echo basalt]

couchdb? idk

Just some other cache database

It's just implementing an interface

But yay I can sleep at night

knowing the network won't explode due to this

[lost matrix]

Doesnt matter if its on the proxy or in redis.
Just a map in redis that knows where every island is loaded.
No need to request it every time a player wants to join.

[echo basalt]

This only runs if the player's island isn't loaded

If it's loaded it just picks that server

I also do some checks on player join to prevent duplicate loads

It's a bit icky because I have a profile system

But it works

(I think)

[lost matrix]

Ok but what prevents you from having a centralized Map<UUID, ServerName> in redis
where you simply let servers write in loaded islands and remove them if they unloaded the island.
Combined with a Map<ServerName, Integer> for the amount of islands which can be used for the load balancing.

[echo basalt]

Right now it's basically just a huge Map<UUID, ServerName> yeah
