[wet sparrow]

the error is that it doesn't go back to the original block. it is as if he did not enter the if.

[tender shard]

what is "game.typedBlocks"?

[tender shard]

what is game.typedBlocks?

[chrome beacon]

and where is that

[brisk estuary]

I'd have to check if the player is moving inside the task right? So when a player is stopped the particles stop appearing too

[tender shard]

does it print "Change true"?

[wet sparrow]

no

[chrome beacon]

Store the position and then the next time it runs check if the position has changed

[tender shard]

does it print "Run Task"?

[wet sparrow]

yes. "Run Task"

[chrome beacon]

That's one if statement with a (weak)hashmap

[wet sparrow]

how i can?

[dim adder]

thx

[wet sparrow]

??

[near mason]

whats ConcurrentHashMap

[lilac dagger]

it's a multiple thread hashmap

it can be edited by multiple threads

[near mason]

what theme is this looks so good

oh

[onyx fjord]

hashmap thread safe

[dim adder]

How can i make that a player doesn't loose his hunger

[tender shard]

cancel FoodLevelChangeEvent

if the event's getFoodLevel is less than the entity's current food level

[sterile breach]

hello, in a gui, it's a bad thing to make a
if to check every possibility of what the item might be? I imagine so? Is there a technique to avoid doing this?

[chrome beacon]

https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

[wet sparrow]

so?

[tender shard]

I usually just apply a PDC tag for the "function" of every item

e.g. "next-page" etc

[chrome beacon]

Show your entire code

[sterile breach]

yes I have already done this system, but I have changed it a little because I do not like this button system, I prefer to keep a single function which recovers the click event

[chrome beacon]

Then do a massive switch statement with PDC data 🤷‍♂️

[sterile breach]

else i can make a switch?

[mellow pebble]

how to decide should event handler have high or low priority or does it even matter that much if we specify it ?

[wet sparrow]

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

what do you need to see?

[chrome beacon]

You usally don't need to set it

[ivory sleet]

sometimes ye

[chrome beacon]

The entire class

[mellow pebble]

how do you decide if it should be like highest or high or whatever option

[lusty cipher]

is there no event for when a book is placed onto a lectern?

do I just have to have a special check with PlayerInteractEvent and check if the clicked block is a lectern?

[ivory sleet]

if u want it to run before or after other event handlers

[mellow pebble]

egh

[wet sparrow]

what class. the listener?

[chrome beacon]

Where ever that code is

or just put the entire project on github so we don't have to has for more code multiple times

[wet sparrow]

is a multi modular project

but i need help only whit this event.

[chrome beacon]

eh I'm just going to do smth else

[tender shard]

Lol

[chrome beacon]

I'm not going to waste another half an hour asking for more code

[twilit creek]

Hello, i have a problem,

    private double calculatePrice(User user, double numTreats) {
        double treatPrice = ((user.hasCustomObject("treats") ? user.getCustomObjectInt("treats") : 0.0) * 100.0) + 100.0;

        treatPrice = Math.min(treatPrice, 10000);

        return numTreats * (treatPrice + treatPrice + (numTreats - 1) * 100.0) / 2;
    }

at this line:

return numTreats * (treatPrice + treatPrice + (numTreats - 1) * 100.0) / 2;

I want to add the price + 100 for every treat, but if the price goes higher than 10000 it should be capped at 10000 and every next Treat should cost 10000. I cant use for loops because if my number to buy is like: 1000000000000.0 it crashes the Server.

You can simple use an Proxy System with functions to reset the server after a match ends.

[mellow pebble]

bruh why did you say ich

dont let server save the world so if it is not saved there will be no other blocks after you restart server

[twilit creek]

Sorry, my bad i am a german programmer and the word "Ich" means "i". It was a mistake from me. Translation at a late time is not good for me. xD

[mellow pebble]

or if you would take different approach but idk if it is better you can listen while game is on for block place of each player and save it into a map and on game end event you can just go through maps or arrays or whatever you want to use to store those blocks and just remove them one by one which will be quite fast 🤷🏻‍♂️

[mellow pebble]

yes i know ich is i hahahah i didnt get what are you even trying to make i mean that is too much math for me im not good with it but i would say from text you sent there is no need for such math

[twilit creek]

i know, i show for different code but there isnt any solution for my problem. 7 Hours of life wasted.

[mellow pebble]

i mean if you want to go 100 for each threat you can go in for loop and make it go price go + 100 until price is 10000 and there shouldnt be number like 1000000000000.0 because it will break out of loop once it reaches 10000

[twilit creek]

I know a good friend told it me at the same point. I try it.

[eternal oxide]

just multiply then Math.min

[mellow pebble]

did you go to university if so what did you study ?

[eternal oxide]

no, university is only for indoctrination

[remote swallow]

Did you do cs in college

[eternal oxide]

no cs wasn't a course when I went to college

[wet breach]

just make an if statement that checks the number and returns appropriately

[remote swallow]

Damn

[wet breach]

so that means its good right?

[pulsar parcel]

Hello, I am trying to check if player has broken wool, and that with switch case get what color is it. My code looks like this, but I am not sure about LEGACY_WOOL. I looked on Spigot documentation, but couldn't find any description. So maybe it's not even possible to do it this way. Thank's for any help

if (e.getBlock().getType().equals(Material.LEGACY_WOOL)) {
final DyeColor color = ((Wool) e.getBlock().getState().getData()).getColor();
switch (color) {
case MAGENTA: TeamData.addWool(Groups.MAGENTA);
break;
case LIGHT_BLUE: TeamData.addWool(Groups.AQUA);
break;
case LIME: TeamData.addWool(Groups.LIME);
break;
case YELLOW: TeamData.addWool(Groups.YELLOW);
break;
case BLUE: TeamData.addWool(Groups.BLUE);
break;
case BROWN: TeamData.addWool(Groups.BROWN);
break;
case RED: TeamData.addWool(Groups.RED);
break;
case BLACK: TeamData.addWool(Groups.BLACK);
break;
default:
break;
}

[onyx fjord]

can PlayerJoinEvent message somehow be component?

(setter)

[wet sparrow]

Block break? And getData.

[pulsar parcel]

Yea block break event

[wet sparrow]

Spigot API?

Versión

[onyx fjord]

1.19.4

[tender shard]

no but you could set it to null and manually send it

[onyx fjord]

aight

whats the internal code for it

is it just bukkit broadcast?

[tender shard]

just loop over all online players and do player.spigot().sendMessage

that takes components

[onyx fjord]

broadcast also does

[tender shard]

it does? oh well then that works too

i rarely use components

[onyx fjord]

aight

yeah me too but this is special case

[twin venture]

hi question , iam trying to think of a system to make for my plugin :

• Timed Items , so its a shop , when you buy the item it will have a time in the lore [the time when it will expire]
  after that , when ever you join , interact click , or damage the item , it will check if its expired .
  what's the best aproch to go with , what Time utils i can use ?

[wet sparrow]

Use a date

Date

Of java

[twin venture]

what i was thinking is a :

[cinder abyss]

Mojang mapping is incredible...

thanks @chrome beacon

[onyx fjord]

would be better if they didnt obfuscate at all 🙂

[wet sparrow]

Expired time? In the end time this will be deleted?

[twin venture]

yes indded

[tender shard]

yes

[tender shard]

yes

[cinder abyss]

well, yes but the mapping "patch" this problem

[twin venture]

it will check , when player join if its expire , when player damage the item , when player do other stuff with the item ..

[onyx fjord]

why obfuscate when you give mappings anyway tho

[tender shard]

except for the fact that the mappings change with every version

[chrome beacon]

File size

[onyx fjord]

how big the difference is

[wet sparrow]

Mmm

[cinder abyss]

well, not really a problem with multi-module

[chrome beacon]

No idea

[onyx fjord]

isnt it like 10 megs

[wet sparrow]

Looks good

Mmmm

[cinder abyss]

obfuscated, it's a problem, remapped it isn't really

[tender shard]

well you then have 10 times the same code in your plugin, just with different mappings

I find this quite annoying

🥲

[cinder abyss]

craftbukkit's elements are a little annoying

[wet sparrow]

Add only most version used

[tender shard]

i got people who complain if something doesn't work on 1.16.2

no idea why they use 1.16.2

[cinder abyss]

for having brute piglins without bug fixes

[tender shard]

this dude is using 1.16.3

[wet sparrow]

Delete support for this version

[lilac dagger]

support only the latest of each major version, problem solved

[wet sparrow]

Yes

[chrome beacon]

Then you get 1 star reviews

[cinder abyss]

the guys who makes me angry

[wet sparrow]

Hahahahah

What is this plugin?

[chrome beacon]

CombatLogX keeps getting 1 star reviews from rule breakers in our discord

[tender shard]

ChestSort https://www.spigotmc.org/resources/chestsort-api.59773/

[cinder abyss]

POV : my plugins

[chrome beacon]

They 1 star because they get muted for a bit

[cinder abyss]

[quiet ice]

I haven't recieved a review in a looong time

[tender shard]

this happened yesterday on my server lol

"yeah sorry" lol

[quiet ice]

Isn't that plugin OS?

[tender shard]

no

[cinder abyss]

pterodactyl

[quiet ice]

ah

[cinder abyss]

1 star : crack recognition

[tender shard]

it was open source but once I removed the github link and raised the prices, much more people bought it lol

[cinder abyss]

🐀

[chrome beacon]

I Will delete
... they won't

[tender shard]

their cracked version only supported 1.16 anyway

[cinder abyss]

A little question :
Do Herobrine is autorized in spigot public resources ?

[tender shard]

that's why they had 2 versions, the free 1.20 version and the cracked 1.16 version

[chrome beacon]

?

[cinder abyss]

because Mojang don't want things with Herobrine

I think I'm not sure

[wet sparrow]

Hahahaha

Lol

[chrome beacon]

They don't care

[cinder abyss]

perfect, I'm adding herobrine in my plugin

using nms

[tender shard]

just call it Heroacid

[cinder abyss]

HeroBrain

HeroBring

[tender shard]

[chrome beacon]

Steve

[wet sparrow]

Dude's I need to make a regeneration system for a arenas like block to block. Anybody can help me?

[chrome beacon]

Not without any information

[wet sparrow]

What information? Only need the use. And proposed

I need to make API for plugins like bungee multi arena world

[cinder abyss]

Where can I find the 1.19 equivalent of 1.18's ClientboundPlayerInfoPacket ? (a doc for this ? a tip to find it ?)

[tender shard]

it's still called like that

[cinder abyss]

(I know it's ClientboundPlayerInfoUpdatePacket but something to find it easily will be better)

[tender shard]

oh wait I only checked 1.19.2

[cinder abyss]

there are different

so I need to do it for 1.19.2 and 1.19.1 ?

with BuildTools ?

(who is making my pc burning)

[wet sparrow]

😂

[cinder abyss]

maybe I need to enter a -Xmx value

but I think it's the processor

[chrome beacon]

Yeah it's the CPU having to decompile

[tender shard]

20 seconds on m2 max 🥲

[cinder abyss]

how can I speed it up or saving my processor life ?

not generating docs and sources

I'll remove this parameter

[chrome beacon]

Get a better cooler?

[cinder abyss]

"C:\Program Files\Java\jdk-17\bin\java" -jar BuildTools.jar --rev %Input% --generate-docs --generate-source %remappedArg%

[cinder abyss]

a better motherboard, compatible, and after a better cpu

and losing 500$ for this

just to compile

[chrome beacon]

You don't need a new motherboard for a new cooler

[cinder abyss]

cooler isn't the problem

I used burning for dying

[chrome beacon]

If it's just the CPU being slow then just go do something else while it's running

[cinder abyss]

well, my english is bad so I need to contourn the path

[cinder abyss]

I don't have any friend...

[chrome beacon]

I usually just watch youtube or smth

My i5 3470 could handle it just fine

Your CPU probably can too

[cinder abyss]

...

we aren't in the same group

[chrome beacon]

Laptop 💀

[cinder abyss]

3* faster without overclocking for you

[remote swallow]

you are not havinga good time are you

[cinder abyss]

true

I saw you and I have the answer... idk

[chrome beacon]

Just go do smth else. Watch youtube on your phone 🤷‍♂️

[cinder abyss]

I think without generating docs and sources it will work

[remote swallow]

add more sysouts or see if its any issues with the url building or something

[chrome beacon]

That won't save much time

Majority is the decompile, patching and recompile

[remote swallow]

making stuff thread safe is hard tbh

its either something throwing an error that isnt caught or its some jank

[cinder abyss]

but I have ~10 minutes of generating docs and sources

[remote swallow]

kek

add a impl some form of a queue

probably?

[thin venture]

Is it possible to detect when someone is unbanned? or what ways could I go about doing that?

oh yes i am using opera GX

so yes

thank you

[pseudo hazel]

if you are not aware of using a vpn you likely arent xD

oh or that

[twin venture]

hi uhh , i have weird problem :

why it does not work ?

this check does not work .-.

should i do a for loop in the lore list and check each line?

[river oracle]

why are you using lore and not PDC

[young knoll]

You would need to have the full line to use contains

[river oracle]

you have to loop through the list and use contains

[young knoll]

Otherwise you need to loop each line and use String#contains

But yeah just use pdc

[river oracle]

or if you're on older versions NBT

[twin venture]

PDC?

[young knoll]

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[twin venture]

yes iam on older versions .

[river oracle]

use NBT

[young knoll]

Then use NbtAPI

Or just NMS

[river oracle]

if you don't use NBT you will end up shooting yourself in the foot

Lore is such a bad way to keep data

[twin venture]

yes i know NBT

[river oracle]

turns out you can have abstracts in enums like wtf how did I not know this, this is genuienly useful

[young knoll]

You what

[glad prawn]

wat

oh

[twin venture]

lets say i want to use NBT

[river oracle]

    ADD('+') {
        @Override
        public double apply(double x1, double x2) {
            return x1 + x2;
        }
    },```

this is valid java code

[twin venture]

here is where i add the lore

[river oracle]

when you add the data? just focus on making the lore look good not on data storage

add the raw data no conversions necessary to the NBT

[nocturne vine]

Anyone know what 7x9 is i need help

[young knoll]

Probably like

12

[remote swallow]

you fuckin what mate

show me more

[nocturne vine]

What is 7x9

[glad prawn]

    CAT {
        public String makeNoise() { return "MEOW!"; }
    },
    DOG {
        public String makeNoise() { return "WOOF!"; }
    };

    public abstract String makeNoise();
}```

[river oracle]

63

[twin venture]

so i can do this right?

[compact haven]

wait what?

that's

I had no fucking idea

that's actually crazy

[remote swallow]

that is great

[young knoll]

Why use a Boolean and not a long

With the timestamp of when it expires

[twin venture]

i can do that too?

[tender shard]

Why should it not be valid?

[young knoll]

Well with a long you can store the expire time in a simple format

[river oracle]

just didn't know that you could add abstracts to Enums is all

[tender shard]

Oh yeah sure

[worldly ingot]

At the end of the day, your enum boils down to just this, which is probably a little more understandable as to why it works

public abstract class MyEnum extends Enum<MyEnum> {

    public static final MyEnum EXAMPLE = new MyEnum() {
        @Override
        public void example() { }
    };

    public abstract void example();

}```

[river oracle]

ahhhhh interesting

[worldly ingot]

Spigot actually uses this syntax for ChatColor

[river oracle]

interesting

didn't know

[worldly ingot]

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/spigot/browse/Bukkit-Patches/0010-BungeeCord-Chat-API.patch#36

Although not abstract

[young knoll]

Could you not have just used a field

[worldly ingot]

Yeah I kind of question that as well. It's not like the enum constant itself isn't already being removed. A { is added anyways

[young knoll]

¯_(ツ)_/¯

[twin venture]

the system is working and it does remove the item after the time usage expired .

need to improve it now :p

[inner mulch]

When is it smart to store data in the player NBT data and when / how can i create my own data files (if they are better)?

[opal juniper]

ugh why using nbt when you could use pdc

[inner mulch]

thats what nbt data of the player is

personaldatacontainers are the nbt data

[opal juniper]

yeah, are you using them?

Why use NBT directly

[inner mulch]

im using pdc, but i feel like a bad developer and it would be better to create a data base

[worldly ingot]

I mean if you can use a database you probably should. It will end up being more performant at the end of the day

[young knoll]

He’s on an old version

[worldly ingot]

If it's trivially simple data then it's fine

[inner mulch]

no

[worldly ingot]

Up to you, really

[young knoll]

Not you

[inner mulch]

is there a way for me to learn how to create data bases, i tried but failed miserably everytime ?

[opal juniper]

yes

[worldly ingot]

Practice mostly. There are different flavours of database. If you want something simple and flatfile you could look into SQLite, but if you want something remote and more robust, MySQL (or MariaDB or Postgres) would be good ones to look into as well

[opal juniper]

https://docs-c18a6sf35-papermc.vercel.app/paper/dev/misc/dev/using-databases Outlines it a bit

[worldly ingot]

tf is that link?

[young knoll]

📄

[opal juniper]

it’s a staging deployment

auto deploys pr’s lol

[inner mulch]

i want to store the clan a player is in, what would be the most fitting for this?

[worldly ingot]

Definitely a DB

You won't be able to access that data unless the player's logged in otherwise

What if you want to get all players in a clan?

[opal juniper]

and you can do some cool sql lookups to get all people in clans

[worldly ingot]

Or kick a player for that matter?

[opal juniper]

does offline player not impl PDH

[young knoll]

Not yet

[opal juniper]

huh

[inner mulch]

guys i dont really understand what you are talking about

[opal juniper]

doesn’t matter, just use a database

[inner mulch]

yes, but i dont know how to do it? do you know a good tutorial?

[opal juniper]

read the link i sent, you will need to learn some basic sql though

[twin venture]

mysql database you would need :

• 2 tables

• a table for clan info itself [ID, NAME, TAG, COLOR, LEADER, KILLS, CLAIMS] this is just an exmaple.

• a table for players it use the ID for each guild , this is how i created my system UUID , NAME , ID , GUILD_RANK PRIMARY KEY (UUID, ID) , [this is also an example.]

its a bit hard and its goona take allot of time to finish but the result in the end is great .

[inner mulch]

thank you for the response, but what does sql mean?

[twin venture]

i think you mean sqlite?

[opal juniper]

it’s the language used to interact with databases

[inner mulch]

so i need to learn another language?

[young knoll]

Yes

[opal juniper]

it’s very simple

[young knoll]

It’s fairly simple tho

[twin venture]

updated .

[worldly ingot]

SQL is mostly English keywords

Syntax is rather self explanatory, but yes, it is a different language

[inner mulch]

okay, i will look into this

[worldly ingot]

And there are different flavours of SQL too. SQLite's SQL isn't 1:1 with MySQL's SQL

[young knoll]

Because heck you

[twin venture]

hi am i doing anything wrong ?
when i buy the item it should set it to the current time of buying :
i bought it now but it set it to 1:24 , now its 1:45 ..

[worldly ingot]

LGTM. Could just be setting the wrong value on your item

[wet sparrow]

Set a format

[twin venture]

each item have diffrent data :

[wet sparrow]

Like this dd/mm/yyyy

Or hh/mm/ss

Date format

To see 01:33 s

Or 01:10:33

[twin venture]

yes i see

oky

let me test it

i only need to put hourly items , you know i won't be using a day or a week or smth .

the value is 1 for the hours

but for some reason its give 2 hours , 53 minute this .-.

[quaint mantle]

How should I go about having a mob never despawn?

[young knoll]

Set it to be persistent

[quaint mantle]

will try

[warm mica]

Whats up fam

[twin venture]

trying to work harder .. ❤️ thx for asking

[warm mica]

And you likely should use OffsetDateTime instead of LocalDateTime as winter/summer time could mess up your logic

[twin venture]

the problem now :
when ever i buy an item from the shop , it set the time to 3 hours , 4 minutes , 20 seconds ..

all items have 1 hour only :

[wet sparrow]

Get te par of hour

Part

Or add only 59 min

No 1 hour

[twin venture]

well some items can have 6 hours in the shop

only hours ..

[wet sparrow]

And get de part in minutes

Ok

You can use getMinutesPart

Or partMinunes

[twin venture]

oky thanks ..

[twin venture]

yeah didn't work ..

[wet sparrow]

Don't work?

[lost matrix]

Dont populate within the constructor. The approach in this tutorial was meant for very dynamic guys that might change every
time a player opens it. If you want to define GUIs that are only initialized once because they are static then you need to externally decorate them.

My actual system deviates quite a bit from the tutorial. I have an implementation for GUIs that are static and one for GUIs that are dynamic.

[wet sparrow]

This version work fine?

[twin venture]

yes and no , it set the incorrect time .

i set it only 1 hour in the config file

but its set it to 3 hours ..

[lost matrix]

What does the duration contain (in millis) in the constructor? Debug msg it pls

And show the code where you add the expiration string in the lore

[twin venture]

ok i figured out why its bugging .. it should set the time of buying [when player accutlly buy it , and not in the Item Constructor

kind of got it xd

[twin venture]

i dont save it in milis .. :
date: 10
time: m

so that mean its 10 minute .. this is how iam trying to make it

[wet sparrow]

works now?

@twin venture

[twin venture]

naah still a bit buggy ,-,

i will fix it tomrrow iam sleepy now its very late 3:18 am :p

[inner mulch]

poland? / spain?

[twin venture]

iraq :p

[echo basalt]

1:19am here

[young knoll]

Wut

[twin venture]

hi i have a question , when this event is triggered?
PrepareItemEnchantEvent

[young knoll]

But it’s 8:29 here

[young knoll]

When the item is placed in an enchantment table

Not sure if it requires that enchantment options actually appear

[echo basalt]

something tells me my sleepy ass can't read

[twin venture]

well iam trying to do is :
if player enchant the item from the itemframe [bought it ] he can drop it or it will drop from him when he die

i only need to check if item is enchanted .

is there a event for that?

[young knoll]

Either that or you time traveled 10 minutes

Which is fun

[twin venture]

ItemSuccedEnchantEvent xd?

[young knoll]

ItemEnchantEvent iirc

[echo basalt]

4500 lines of code, 11 interfaces

can do better

[twin venture]

welp i don't have that

is there another way?

[young knoll]

EnchantItemEvent

[twin venture]

yes that's the correct one , i just found it from google :p

should i do remove key?

if i want to remove a nbt tag?

USING this one ..

[echo basalt]

Hmm I wonder how I can make an extensible "custom data" system that still has full database support

I'd make a Map<String, Object> but that is funky to serialize when it comes to sql and mongo

Maybe an interface but then each one needs to have serialization logic for literally every single type of database that exists

I think my best approach is to probably just fire events and let plugins handle its own loading logic

[wet sparrow]

lol

[young knoll]

Hmm

My expert analysis concludes that cow

[quaint mantle]

Can you call World#save async?

[wet breach]

for sql you can always do blobs

[echo basalt]

Yeah but what if the data isn't serializable?

[buoyant viper]

personally i think data can always be serialized if u try hard enough

[echo basalt]

Well

good luck serializing a socket

[buoyant viper]

oh no i didnt say im going to try it..

[wet breach]

all data is serializable

[wet breach]

sockets are not data

they are a transport layer

but you can however serialize a socket object

[echo basalt]

A java socket object

[wet breach]

Just turn the object into a byte

and then store those bytes into the blob

you could then reverse it

[echo basalt]

Ehh not a fan of that

Because I can't do queries on that object

[wet breach]

why not?

[echo basalt]

Let's say I want to add 2 fields

Level and points

I can just store that in a collection and serialize that into a blob

[wet breach]

what does that have to do with socket objects?

[echo basalt]

But it won't play nice if I want to get the players with the most points

[echo basalt]

Socket objects are not going to serialize nicely either

[wet breach]

no because ideally you wouldn't do that at all

[echo basalt]

Yeha that's what I'm thinking

[wet breach]

since there is typically nothing in the object you don't already know

[lost matrix]

Im using a custom Gson adapter to serialize literally anything to bson for mongodb

[echo basalt]

Yeah but I'm not limited to mongodb

[lost matrix]

Drawback: It heavily relies on reflections

[echo basalt]

I do that at work too

[slender elbow]

serialize a socket... what kind of fever dream is this

[wet breach]

just fyi, blobs can hold files too. So if its easier to store the data in a file like structure you could just toss that into a blob as well

[echo basalt]

I'm working on a sharded skyblock system and I like the idea of having plugins being able to append their own data to islands but it'll be a pain to actually do the IO for the 19 database types I support

[lost matrix]

Well if you want to support different databases then you need to first serialize
your data into a common format (json for example) and then write an adapter
from your common format to the different data stores:

• json -> json [FlatFile]
• json -> bson [MongoDB]
• json -> SQL Model [SQL]

[echo basalt]

Right now my database stuff is just an interface with the methods I want and each driver does its own query logic

[wet breach]

and you can query file types and names as well to make your queries easier

just to give you an idea how versatile a blob really can be lmao

[echo basalt]

But I see some idiot trying to hook a shitty little plugin and trying to append a whole bukkit player

[wet breach]

lol

thats part of fail safe logic

[echo basalt]

And that just won't play nicely

[bitter rune]

I am saving a number as a double by .01, and when increasing said number at times it's pretty ugly (0.023434) type ugly. Is there anyway with a double to round to the nearest hundredth?

[echo basalt]

So my idea is to just write events for everything and let plugins do their own logic

[lost matrix]

Yeah i feel like you will end up with Entity, Player, World etc fields in objects.
In this case recursive reflection serializers just break.

[echo basalt]

That way they can adapt their database drivers to have the most optimized queries

[wet breach]

yes

[echo basalt]

Instead of some fancy algorithm written by an idiot (me)

And I don't get the blame when things break

who am I kidding I'll still get blamed

Maybe I could make some sort of transient map for placeholders

But that's about it

[lost matrix]

I think the best performance would be to just truncate the number by casting.
You can add 0.5 to round it to the nearest full number

[young knoll]

So you’re telling me I can’t stick the entire server into your database?

[echo basalt]

Nope

[young knoll]

;(

[river oracle]

just tried to serialize CraftServer into your database any reason why its failing???

[echo basalt]

All fun and games until that one degen tries to serialize the whole world and push an 18tb blob to an sqlite database

[wet breach]

do you just want to round without caring about precision or do you want to round any number to nearest hundredth?

I will just give you both ways

[lost matrix]

    double num = 0.00255;
    double rounded = ((int)(num * 1000)) / 1000.0;

    System.out.println(num + " -> " + rounded);

Out

0.00255 -> 0.002

[wet breach]

double x = 1.234;
double y = Math.round(x * 1000.0) / 1000.0;

BigDecimal a = new BigDecimal("1.234");
BigDecimal b = a.setScale(2, RoundingMode.DOWN); // => BigDecimal("1.23")

[echo basalt]

So yeah I might just avoid that problem entirely

[wet breach]

oh 7smile7 got the first way nice

[bitter rune]

Sorry using Google as well.

[river oracle]

this is exactly what i do for my database

granted I use this database called Nitrite so I didn't have to fuck with SQLite

no MySQL support for my system yet though

[echo basalt]

I got all forms of sql and mongo in atm

I was gonna do an indexed flat file but it was getting ugly

[young knoll]

Doesn’t sql have a json type

Or is that only some flavours of sql

[river oracle]

I don't have to use my database much though. Since I don't usually work with Data heavy plugins I can usually store in PDC or sometihng with minimal issues

[river oracle]

I believe it has an official json type

[wet breach]

you would need something like an xml file or some similar type for that

for binary, it would be something like csv

[echo basalt]

I still need to add prometheus support to my metrics abstraction

[inner mulch]

Is there a way to remain the name tag, even tho the player is invisible?

[echo basalt]

Just got influx atm

[bitter rune]

In 2 weeks I'm going to start messing with NoSQL I understand the very basics of databases but I need to expand my knowledge

[wet breach]

you would need to use entities for that I believe

use an armor stand and what not or if on new version you could try out the display entities for it

[inner mulch]

ok

[echo basalt]

Are there any other low-latency caching databases other than redis?

[lost matrix]

I urge you to write your data into files first for a while

[wet breach]

MySQL

[lost matrix]

Kindof Hazelcast

[echo basalt]

Dragonfly hmm

[bitter rune]

It's not for Minecraft although I'm using Minecraft as a learning playground.

[keen zinc]

Can anyone help

[echo basalt]

Bruh

[lost matrix]

?ask

[undone axle]

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. Create a thread in case the channel is already in use!

[keen zinc]

I created a smp like hypixel but I want that my lifesteal npc have the only access to the lifesteal plugin

Plss

Someone suggest me this server

[lost matrix]

Show us some code

[young knoll]

I don’t… think they are writing any code?

[keen zinc]

Which code

[echo basalt]

Scylladb huh

[lost matrix]

Just realized lol

[echo basalt]

Grr

[keen zinc]

Didn't understand??

[compact haven]

what in the world

[echo basalt]

Someone explain

[wet breach]

there is also memcached as well

[lost matrix]

#help-server
PS: Keep creating hypixel like smps. We dont have enought of them.

[echo basalt]

Yeah I might just hook into all those

[compact haven]

[echo basalt]

I've had that one mf asking for amazon s3 support

[lost matrix]

lol

[bitter rune]

I used to like denizen plugin that works with citizen, it was a good stepping stone to understanding how to make my own plugin

[lost matrix]

Buckets. Just throw it in there.

[echo basalt]

Don't laugh it was your employer

[wet breach]

well aws does have their own caching mechanisms too

[lost matrix]

Which one?

[echo basalt]

Minecrypto

[wet breach]

but I generally don't incorporate such things since they cost money to use lol

[lost matrix]

Ah lol

[echo basalt]

I'm on my journey to support more database types than luckperms

Might even write a web app where you fill out a form and it provides the perfect config files lmao

I'm bored :/

[young knoll]

Can I store it on GameCube memory packs

[echo basalt]

Uh

Good luck

[young knoll]

https://m.youtube.com/watch?v=JcJSW7Rprio

If you can’t provide those storage options I don’t want it

[echo basalt]

Harder drive sounds like my mental state atm

[young knoll]

He stores data on Tetris

And Covid tests

[lost matrix]

I wanna write my own obscure database in Ruby, make it popular with your
users and create a horrible serialization workflow.

[echo basalt]

Bet

[wet breach]

you would need like 100,000k to just have 800GB

[echo basalt]

But yeah I'm thinking of a webapp that does all the logic locally

Like a static page with a bunch of js

[lost matrix]

Just efficiently compress your data 😄

[wet breach]

I suppose 1,000 of them for 8GB would suffice for a small DB

but the problem is going to be how you how you hook up 1k or more of them to use them

[echo basalt]

I do want to fix my sleep schedule but this sounds fun

[wet breach]

compliment it with terrible support and always in a polite way tell them they are wrong indirectly

[lost matrix]

Image having to split a single object onto multiple cards and then having
to write additional data on other cards to keep track of which cards contain
correlating data

[wet breach]

this would get really interesting XD

[lost matrix]

Im currently on a very weird 4h 3h 1h split... exams fked me up this year

[wet breach]

would end up needing more cards because of the extra data needing to be saved lol

[echo basalt]

I finished school

I made a presentation of a product that didn't exist and claimed the datacenter I had it on had a network outage

91.5%

[wet breach]

well now you have to elaborate on this

[young knoll]

4 hours of sleep, 3 hours of awake, 1 hour of N A C H O?

[echo basalt]

So we had to do a final project

And we were aware of this for like 3 years

Anyways I did some poor choices and got a massive project and simply didn't manage my time well

[wet breach]

for 3 years you didn't manage your time?

[echo basalt]

It was like a webapp that did spatial audio based of your position in-game

[wet breach]

alright continue lol

[echo basalt]

Nah we only had approval like

in december of the final year

But we had 3 years to plan and think

anyways I had no fucking idea what to do

and just thought of this in like february

hired my brother to help me finish it in like may

Dude spent a month sitting on his ass and on the last week he tells me he had nothing done

So I was like "fuck it, I'll present next year"

Went there just for shits n giggles and my hardcode network teacher just went to me and said

[wet breach]

this exists btw

[echo basalt]

"go home, sleep, wake up and drink like 5 red bulls"

and basically told me to make a "theorical presentation" which means I had no product but the research alone was worth a lot

So I made this entire powerpoint in like 7 hours

Got it looked at by the teacher like 30 minutes before, did last-minute fixes and presented

Had like the top 3 grade or something

[wet breach]

so much for hired help

[echo basalt]

yeah he's basically disowned now

left there hella happy, went to domino's, got home and passed out at like 3pm

[wet breach]

but yeah spatial audio stuff exists though as product related things especially with games

[echo basalt]

woke up at 6am the following day

[echo basalt]

OpenAudioMC or whatever

hadn't heard of it back then

but the idea was that it was a plugin and a web app

And all the spatial audio logic happened with the WebAudio API

lot of sockets, wrote a whole protocol

It was a spring server talking to all the minecraft instances and doing all the audio routing for the web clients

[bitter rune]

Thanks worked like a charm

[echo basalt]

Also all the images I had of the web app were made in photoshop

[wet breach]

still, kind of funny you did a presentation on something you believed to not exist. Either way still cool you got a good grade without presenting a physical thing

[echo basalt]

it was a really beautiful presentation

I talked about multithreading, security, firewalls n shit

Even gave pointers that I wanted to do internal metrics and pulled the work grafana dashboard

and they just bought it

[wet breach]

lol

when you spend more time on the presentation to fool everyone then the actual thing 😛

[bitter rune]

Speaking of, irl I'm not someone who is good with people, somehow communications was my gpa, on top of that the last presentation I scored 5 points above for creativity

[echo basalt]

Nah I did put in the work

[wet breach]

good thing this wasn't some sales pitch

[echo basalt]

7 hours on the presentation and like 12 trying to do the project

people worked like 6 months on their projects and got shit grades

but there were also a lot of shit ideas

there was this dude that made an AI with a human-sounding name so it tripped on most conversations

[wet breach]

what was the theme for the finals?

[echo basalt]

You picked your own project

programming-related

[echo basalt]

Anyways the way for his AI to signal it was listening was to just overlay a stretchy low-res image occupying half the screen like it's some kind of arabfunny meme

[wet breach]

lol

[echo basalt]

https://tenor.com/view/imdagawd-gawd-allah-praise-osu-gif-17933270

reminds me of this gif

And it had like 3 commands

worst part is that it was just a fork of a github project with like 2 subcommands

One of them was to open spotify, which had the .exe path hardcoded

And I don't remember the other one which means it was useless

[sharp cargo]

Hi guys, sorry for the inconvenience. I'm making a Plugins in Spigot 1.20.1. But it seems to me that a lot of things have changed. Is it possible to get help? (Sorry, I'm a beginner..)

            PlayerInventory playerInventory = event.getPlayer().getInventory();
            ItemStack itemInHand = playerInventory.getItemInMainHand();

            if (itemInHand != null && itemInHand.isSimilar(new ItemStack(Material.DIAMOND_AXE))) {
                String itemName = itemInHand.getItemMeta().getDisplayName();
                if (itemName.equals("§4Reload")) {
                    event.getPlayer().sendMessage("Vous avez cliqué avec un item nommé '§4Reload'");
                } else {
                    event.getPlayer().sendMessage("Vous avez cliqué avec une hache en diamant !");
                }
            }
        }
    }
}

[echo basalt]

Yeah you don't compare items with their name

And isSimilar does meta checks, only skips amount checks

ItemStack#getType and

?pdc

[undone axle]

https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/

[echo basalt]

Are your homies

[young knoll]

Comparing the event action with a string is… interesting

[echo basalt]

I'd use it to see if it's a RIGHT_CLICK because it can either be block or air

but yikes

[young knoll]

I just use an ||

It’s 2 conditions I’m sure the cpu will live

[remote swallow]

go make an abstract class that has util methods for events

if(isRight(event))

[young knoll]

Or just

PR it into the enum/event

[remote swallow]

no

[lost matrix]

if (event.getAction() == Action.RIGHT_CLICK_AIR)

if (itemInHand.getType() == Material.DIAMOND_AXE)

But you should check custom items by tagging them and then checking for this tag.
Look at the persistent data container link from above.

Hm item in hand cant be null iirc

[echo basalt]

Depends on the server version

I still do nullability checks

Because ancient versions sometimes give issues

Better safe than sorry

[sharp cargo]

It gives me this error:

}

[young knoll]

You can also just use event.getItem to get the item involved in the event

[lost matrix]

That would be the proper way actually. And check which hand the event was fired for.

[young knoll]

What the heck is ItemType

[lost matrix]

I was just looking at the javadocs

[livid dove]

Hey smile whilst ur around. Ever thought of taking ur modern approach article for guis and doing a custom inventory one? 😁

Very closely aligned approaches I'd imagine

[lost matrix]

What do you mean by custom inventory?

[livid dove]

E.g a custom barrel that can age brews.

A custom inventory that can make custom items (that works with in panel itemstack buttons) etcs

E.g: not just a menu, but an inventory with additional functionality depending on what's done in it

[sharp cargo]

Its giving me this error with the code

Caused by: java.lang.NoSuchMethodError: 'org.bukkit.inventory.ItemType org.bukkit.inventory.ItemStack.getType()'

        ... 23 more

[lost matrix]

That... sounds like a GUI to me 🙂

[livid dove]

I mean there is added subtlety.

Persistsncd for one

[drowsy helm]

thats more of the underlying system behind it than a gui itself

the gui is just the fascia for the system

[young knoll]

You’ve got some weird dependency in your development environment

[livid dove]

I mean that's fair to an extent , but utilising the ability to pin down what inventory an event is dealing with using a simnilar approach to the modern gui approach could be a shout.

[lost matrix]

Inventories are merely a way of letting the user interact with, and modify data.
You can create a Barrel, store some data like brewing content and different settings
inside its PDC and simply use an inventory to let the user modify this data by placing
items in it or changing the brewing temperature etc.

[remote swallow]

the new pr right

[young knoll]

Yeah I guess that is from the new PR

[sharp cargo]

I only have spigot-api-1.20.1.jar

[lost matrix]

Inventories or GUIs itself should usually not store anything. They should be stateless
in most cases and just provide functionality in a UI

[young knoll]

But the heck are they doing with that build

[livid dove]

Oh aye I figured that's the approach don't get me wrong. I was asking if ud ever considered an article about it.

Ur a good teacher and I admire your work 😁

[lost matrix]

Hm. Im currently updating my plugins and afterwards i might write something in the forum again.
Not sure what topic since ive done mostly machine learning and image processing in the last months...

[young knoll]

How to ASM

Kek

[river oracle]

Keep that away from spigot peoples

[lost matrix]

How to break everything beyond comprehension in the hackiest way possible (ASM)

[young knoll]

But it’s fun

[lost matrix]

Yeah especially if you do meta programming

[livid dove]

I mean tbh considering ur thread style, maybe a guide on using async properly?

[lost matrix]

I got "threading for beginners" but halfway through i realized that this is a huge topic
so it kind of cuts out at the end

[livid dove]

Ooor one that I'd love to collab with a few authors on as a dream pet project:

OOP Design Patterns: Taught through examples of their utilisation in spigot plugins.

[sharp cargo]

Was this post a response to mine?

[young knoll]

Mhm

[livid dove]

Hey throw it my way and I'll finish it :L

[young knoll]

Where did you get your spigot api jar

[river oracle]

Threading for beginners more like slapping CompleteablFuture around everything and go full yolo

[lost matrix]

To be honest CF are very nice. I mostly use them when doing multithreading.

[river oracle]

I've never used Thread from Java

I only sue CF

[young knoll]

Oh fuck don’t sue

[lost matrix]

I sometimes use executor services

[river oracle]

Used those in my last plugin

[lost matrix]

But then again, you can just pass them to a CF and have a nice reactive pattern instead

Fk it has been so long. What did i forget?

Ah just read remapped and then it came. Need to run bt with the remapped flag. Woops

[river oracle]

Reminds me bt gui coming soon woohoo

Just gotta finish my part:( I'm a slave

[lost matrix]

What gui framework?

[young knoll]

Swing

/shrug It’s cross platform and doesn’t make the jar huge

[lost matrix]

Has been a while until i realized you can stylize swing components with css

[sharp cargo]

On a site, I don't remember, but where am I supposed to install it?

[young knoll]

?bt

[undone axle]

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

[young knoll]

Or since you just need the api you can use the maven/gradle dependency

[lost matrix]

[river oracle]

Hope it wasn't malware fingers crossed

[lost matrix]

"ItemType"

Idk man

[river oracle]

Thats official

You must not be up to date on the registry pr

It's in an experimental branch of spigot atm

[young knoll]

What site is distributing that

[lost matrix]

Nope im not. Pretty much 4 months behind

[young knoll]

https://tenor.com/view/cat-fall-ground-drop-oof-oop-die-play-dead-gif-18928206

[river oracle]

Prob the site that shall not be named at the top of search results

[young knoll]

Yeah but why tf are they

[lost matrix]

Anything cool coming from 1.20?

[young knoll]

Sigh it’s best to not question it

[young knoll]

Hopefully the component PR

[river oracle]

I'm biased but InventoryView#setTitle already merged

Sorry I use setTitle way too much not to be happy about it lol

[young knoll]

Lol

Not much new in 1.20 yet

[lost matrix]

Interesting. Does it send the inventory + items to the player again?
Or is renaming an open inventory now possible.

[river oracle]

It uses the client quirk by sending a container with the same ID and different title

[drowsy helm]

you could always do it with packets

[river oracle]

It's done with packets internally

[lost matrix]

Ive tried that in 1.18 and it cleared the item contents

[river oracle]

It doesn't

Tried and tested :P

[young knoll]

Not anymore I guess

[lost matrix]

Alright then. Nice 😄

[young knoll]

This changelog site is great

Phoenix is best

[river oracle]

setTitle is misleading its more like sendTitleChange but the InventoryView stores the new title

[lost matrix]

Woo, dont need to fix my plugins

[river oracle]

Yay

[young knoll]

Api wise 1.20 didn’t change much

Just signs

Actually NMS wise not much changed either

[river oracle]

I love when NMS doesn't change

[young knoll]

Mappings certainly help with that

[lost matrix]

The change to mojang mappings was a good idea

[young knoll]

Shoutout to Mojang for actually making them usable license wise

[lost matrix]

Interesting

[young knoll]

?

[lost matrix]

Just some things ive discovered in Player

You can now open a ton of GUIs via the api

[young knoll]

You’ve been able to do workbench for a long long time

Don’t remember for the others

[timber crescent]

can i hide blocks from certain players? and other people can just go right thru it?

[slate mortar]

i swear i wanna end my life

[slender elbow]

I mean same but for the wrong reasons

[slate mortar]

i somehow dont trust fabric

it says it takes 3ms for this process

i somehow doubt that

and i just realized i'm in help-dev channel

now i wanna end my life even more smh

[slender elbow]

can we hold hands while at it

[slate mortar]

yes, please

[buoyant viper]

can i join @slender elbow @slate mortar

[slate mortar]

oh death?

[sterile breach]

No, there are not static. So Add param in the constructor si bad ?

[slate mortar]

sure

[sterile breach]

Why ?

[lost matrix]

You mean populating within the constructor? Because it breaks inheritance.
The constructor should not decorate the inventory.

[sterile breach]

Ah no, i don't good understan your I thought you were saying don't add arguments in the constructor

So i décorate on open?

[buoyant viper]

well i meant handholding but yeah that too

[sterile breach]

And, why decorating on constructor is bad ?

[lost matrix]

Just do it and if it doesnt cause any problems then you should be fine.
Its only a problem if you want to continue with the abstraction pattern.

[sterile breach]

Okay, but why decorating in constructor break the inheritnace ?

[rare kraken]

I'm updating some old plugins from pre 1.19 to some modern versions.

The main feature I'm updating is some custom command stuff, is there any good guides on what has changed with Brigadier. In the past I was able to get the ArgumentItemStack directly but now it seems like it needs a CommandBuiltContext?

[lost matrix]

Because if you have a child class which relies on the decoration being done at a later time
then you wont be able to undo it because the parent constructor needs to always be called.
Just use it and change it if you have problems.

[sterile breach]

I don't have constructor parents the constructor is in the child

[lost matrix]

Just dont decorate inside the abstract class' constructor

And if you call it in your child class then make it final

[sterile breach]

So if i décorate it in the child is good ? And Why final?

[lost matrix]

So you dont extend it and wonder why it breaks later on.

[sterile breach]

He never breaks.

Menu (abstract)

Testmenu extend Menu

In the constructor of testmenu.

[lost matrix]

But calling it in the constructor is still dirty in my opinion.
Its an implicit implementation detail. You have to remember to
call it in every childs constructor.

[lost matrix]

What if you want another abstraction level?
Then it breaks

[sterile breach]

What do you mean on another abstraction level?

[lost matrix]

Menu
-> PaginatedMenu
-> -> PaginatedBookMenu
-> -> -> BibleMenu / CookbookMenu / TravelersGuideMenu

If you call decorate in the constructor of PaginatedBookMenu
but CookbookMenu relies on the decoration being called after
the constructor, then you are fked.

[sterile breach]

My pagnited menu system is implémented in mu décorate but i understand your raisonnements

[lost matrix]

But more importantly: Its an implicit implementation detail
If you have to "remember to implement it" then thats a bad design.

[sterile breach]

So i add it on the opening? Or on the getter getinventory?

[lost matrix]

If the GUI doesnt change then you should not decorate it every time a player opens it.

[sterile breach]

No, he change

[sterile breach]

so I must not have a constructor in my menu?

[bitter rune]

[lost matrix]

You dont need the name of your class. You need an instance of your class.

[daring schooner]

Guys, is there a nice way to listen to packets in mojang mappings, although i know i should use protocol lib stuff but i would like to learn it without it, where i should start when trying to listen to packets

[sterile breach]

if i don't need I don't need to access/modify the items after the constructor, can I leave it in the constructor?

else I made this code with a method to open it is better?

public void Open() {

    System.out.println("oo");
    this.setMenuItems();
    System.out.println("bb");

    this.owner.openInventory(this.inventory);
}

[sage patio]

is there any events for health generation and hunger?

[daring schooner]

EntityRegainHealthEvent and FoodLevelChangeEvent are they way to go

[sage patio]

thank you

[lost matrix]

You need to inject your own packet handler into the netty pipeline

Its not easy to find out how to do this on your own. But you can grab code from someone.

[daring schooner]

Ok so netty still a thing, cause i found an old spigot post about using it. I'm trying to go deep into how minecraft server communicate and understand more about network in general. Thanks for the help, imma study how they did it and try to get my own solution

[lost matrix]

You need to add your handler before the "packet_handler" component in the current netty pipeline

[daring schooner]

Hm okay, that makes sense

I saw i need to create an reflection to be able to read the packets

[lost matrix]

Only if you dont use NMS

[daring schooner]

Its a pretty extensive topic damn

[daring schooner]

So the reflection is used when i intercept the packets outside the NMS scope? Idk writing my own listener non-minecraft/nms/spigot/bukkit related

[sage patio]

the default walk & fly speed is 1?

[lost matrix]

This is how the pipeline looks like

You will get an Object if you register your own handler before the "packet_handler"
If you have nms on your classpath then you will actually have the nms packet at your disposal.
If not then you just have an Object. In this case you need to use reflections because you
dont know what the packet looks like

[chilly hearth]

e

[daring schooner]

Oh, got it

That's exciting imma go write some code

Thanks for the help @lost matrix

[alpine urchin]

could help to learn basics of netty

[daring schooner]

I was going trough the docs rn lol

[alpine urchin]

good good

you could look into how these projects do it

[daring schooner]

Thought that was a wise ideia to do.

[alpine urchin]

protocollib, viaversion are open source

[daring schooner]

but thanks for the tip

[alpine urchin]

mine also does it

xd

so yeah

but still knowing netty basics works

knowing how to make a handler

[daring schooner]

What project is yours?

[alpine urchin]

different kinds

order of the pipeline

so you know why you want to be infront of packet_handler

[daring schooner]

Imma jump and trying to develop something using netty to get the feel

[alpine urchin]

packetevents

thing is

mine and viaversion’s project dont want the nms object

[daring schooner]

I got really interested into this networking side of minecraft servers

[alpine urchin]

we want the buffer

so we need to be placed differently in the pipeline

we aren’t next to “packet_handler”

but the reflection code to inject to access the pipeline you can take from us

[daring schooner]

Mainly because of how minecraft anti-cheat works

[alpine urchin]

i see

[daring schooner]

Thats sound really nice, thanks

[alpine urchin]

there’s anticheat communities

[daring schooner]

Just got into your git repo

[alpine urchin]

although sometimes can be toxic

[daring schooner]

Yeah, i don't have good experiences with coding communities in general

[alpine urchin]

my general advice for anticheat development is study the client

[daring schooner]

This one is pretty chill

[alpine urchin]

its reallt digging into mc source

seeing how client behavior works

making checks for it

but writing injection code for packets on your own itself won’t help you anticheat wise

[daring schooner]

Oh, i was diving into a decompiled version of minecraft made by forge for creating a custom client

[alpine urchin]

but if you desire to do that, go ahead

[daring schooner]

Idk if its legal but, old times, old crimes

[alpine urchin]

if you don’t distribute your client jar then its legal

[daring schooner]

Just want to learn how it works.

[alpine urchin]

that would be leaking minecraft

[daring schooner]

Might look at going for anti-cheats after

[daring schooner]

Oh, i'm safe then

[alpine urchin]

aight

[daring schooner]

oof

Thanks for the Help and the Repo

[alpine urchin]

you can modify the client on your computer

for yourself

following the EULA

it asks us to just not make grief mods(cheats) :)

if you have any basic netty questions i can answer

in netty handlers are kind of like listeners

event listeners

[daring schooner]

Sure, imma hit you with some if i can't figure it out in my own

[alpine urchin]

there’s multiple cause they transform the data from one format to another

some handlers decompress

some decrypt

[daring schooner]

Mojang TOS are don't make capes, don't make cheats lol

[alpine urchin]

some convert from buffer to your nms object

so therefore its important to know where to place yours

you be after the handler that converts to nms

but then pipeline has an interesting order

incoming packets are fired from left to right

[daring schooner]

My main goal now, is to listen to when a player interact with a client-side entity.

Basic NPC stuff

[alpine urchin]

outgoing packets from right to left

[daring schooner]

Just to undestand how to intercept it

[alpine urchin]

why not use a packet api

such as protocollib or packetevents xd

[daring schooner]

I'm copying your messages to my nodepad 😂

[alpine urchin]

since its your main goal

[daring schooner]

Oh, yes in the past i used the libs to do some freelancing work

But i want to develop it using no lib to learn how it works

Like an scavenge thing

[alpine urchin]

okk

[daring schooner]

idk lol

[alpine urchin]

the pipeline stuff makes sense?

[daring schooner]

Just out of curiosity and passion

[daring schooner]

Yeah Yeah, i can see it

[alpine urchin]

if we look at this

[daring schooner]

now i need to take the logic to code

[alpine urchin]

most of these should make sense

by the names

left to right is incoming

what do you expect decrypt to do

to the buffer

the bytes

[daring schooner]

I couldn't indentify from what direction was what on my own

but your explanation of it makes sense

[alpine urchin]

splitter splits them up sometimes packets are chunked together when sent

decoder converts from buffer to nms object

[daring schooner]

That sounds like websockets, but i might be tripping

Not the NMS part tho

[daring schooner]

hm, ok

i'll try to get something running here

Thanks for the help dude

[dim adder]

Hello, does anybody know how I can check in the PlayerInteractEvent if the interacted item is a item in the players inventory?

[daring schooner]

I don't undestand your question. You mean like if the player interact with a diamond block if checks if the player has a diamond in the inventory or a diamond block?

Cause if this is your question you can use a code like this

    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        Block interactedBlock = event.getClickedBlock();

        if(interactedBlock == null) return;

        Material interactedBlockType = event.getMaterial();

        Inventory inventory = player.getInventory();

        if(inventory.contains(interactedBlockType)) {
            player.sendMessage("You have interacted with an item that's in your inventory!");
        } else {
            player.sendMessage("The item you interacted with is not in your inventory.");
        }
    }

I didn't run the code to test it

idk if it works 😂

Oh, it wont check the diamond tho only the block

[sage patio]

what is the best way to disable default hunger? canceling FoodLevelChangeEvent makes level change by foods get canceled too

[dim adder]

so if you have a lever in your inventory and your right-click it, function a should run, but if a right click a lever that is in the world, then function b should run

[daring schooner]

  @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        // Get Player and the world block the player interacted
        Player player = event.getPlayer();
        Block interactedBlock = event.getClickedBlock();
            
        // Guard Clause to check if block is null
        if(interactedBlock == null) return;

        
        // Get Type of the block and the player inventory
        Material interactedBlockType = event.getMaterial();
        Inventory inventory = player.getInventory();

        
        //Checks if the inventory contains any stack with the interacted block material
        if(inventory.contains(interactedBlockType)) {
            // Run if the inventory got any similar block
            player.sendMessage("You have interacted with an item that's in your inventory!");
        } else {
            // Run if the inventory doesn't got any similar block
            player.sendMessage("The item you interacted with is not in your inventory.");
        }
    }

I commented the code out

[daring schooner]

If you have a lever in your hand and interact (Left,Right Click) with it in a Lever (Block), it will trigger the first message, if the block isn't the same or you don't have the item in the inventory it runs the second message

You might wanna add some Item Specific Logic to complement the code

I also recommend running this code to understand what it does before start coding with it

[daring schooner]

I don't get why the player need to eat if they don't get hungry? Anyway you can create a bukkit runnable that sets the player saturation to 20 every 20ticks (1 sec)

I think this is a workaround

can't think of anything else rn

imma do some research

[lost matrix]

You can change that in the spigot.yml iirc

[sage patio]

yea i figured out there is a gamerule called NATURAL_REGENERATION

i changed that to false and created a runnable to remove half a hunger each minute

[daring schooner]

True, in the hunger field there are the exhaustion

[sage patio]

because its for a roleplay server

they have to call medic or go to hospital to regain their health

[daring schooner]

Oh, makes sense lol

[lost matrix]

Isnt this for regaining health through hunger?

[sage patio]

no

[sage patio]

what d u think about this? D:

[daring schooner]

lmaoooo, thats so good

[sage patio]

i'm disabling that with EntityRegainHealthEvent too* sorry

[sage patio]

thanks

[daring schooner]

What a nice ideia

You did you customize the UI?, using an Rest API or are those placeholders value?

[sage patio]

i did that with a text shader inside a resourcepack

so the text shader modifies the position of my actionbar

to top-left of every screen in any resolution

[lost matrix]

Making multiple lines is the tricky part

[daring schooner]

That's interesting

[sage patio]

well i move each line to left by their previus line

its complicated

[daring schooner]

Doesn't it change resolution wise?

[sage patio]

i don't understand
