[maiden thicket]

ike reminscing abt manhunt rn

[lost matrix]

Also checking equals like that will randomly fail.

[maiden thicket]

multiply the vector by direction

i believe

[rough drift]

location.clone().add(location.toVector().normalize().multiply(5));, do i just add location.getDirection() or smt do the normalized vector?

[maiden thicket]

i usually do

[snow compass]

The issue is when bukkit/spigot do the look up of the class or more precise when it "look up the method via reflections" So don´t this way stop with only the method bu also read whole class.

[maiden thicket]

vector.multiply(direction.multiply(whatever))

[lost matrix]

Check the diff between the inventory during and one tick after the event.
You can also go through all the click actions of the event and predict the outcome. This however is very labour intensive and error prone.

[maiden thicket]

so like i.e. when u wanna send a player forward in the direction theyre facing

[eternal oxide]

Thats wrong. java location.clone.add(location.getDirection().multiply(x));

[charred blaze]

do it please

[maiden thicket]

it would be

player.setvelocity(player.geteyelocation.getdirection.multiply(...));

sorry parentheses too annoying on mobile

cba

😭

[somber sequoia]

Ok thank you

[lost matrix]

Im currently indexing. Gradle being a slow poke again.

[rough drift]

not moving the player @maiden thicket

[maiden thicket]

well what are u trying to move

[rough drift]

I'll try this

[rough drift]

A position

[maiden thicket]

just a location in general?

[rough drift]

Just need for particle spawning, I got everything apart the movement for that lol

[maiden thicket]

ah yeah try elgar's then

are u doing something for foolish lmao

[rough drift]

once the movement is done then yeah i am finished

[rough drift]

nah

Messing with particles

[maiden thicket]

ahh

i had my particle fun for 10 minutes every 2 months

its fun kinda

[rough drift]

Well and making a shape renderer :D

[maiden thicket]

i used the tutorials all over spigot's page

theres this one guy

who has like so many helpful resources abt vectors and particles

[rough drift]

ye it's been a while since I did vector maths

[maiden thicket]

https://www.spigotmc.org/threads/tutorial-lets-learn-a-thing-about-math-first-steps-in-animations.111238/

this broski

[rough drift]

well I almost got it working

I am encountering some issues with my particle spawner, but that's fine

I know how to deal with it

[maiden thicket]

ah

W

[rough drift]

This needs to be cleaned up lol

[quaint mantle]

Never say that again.

[rough drift]

Messed something up somewhere

[old sail]

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Player.html#setResourcePack(java.lang.String)

Can I put the local file as url parameter?

It doesn't seem to work
p.setResourcePack("root/server/texture.zip")

[quiet ice]

I do not think so because that would not be recieveable by the client

[ornate heart]

If I were to set it to false would it just give them 5 hearts? I don't understand this at all. I just want the player to have 5 hearts.

I've done this before and I haven't had to mess with health scale at all.

just the attributes.

[red sedge]

how would i set the drops of a entitydeathevent

[ornate heart]

I think you can manipulate e.getDrops

[lost matrix]

Im not sure if ProtocolLib has proper abstractions for this packet.
Its very convoluted.

[ornate heart]

Yea, I was right. There was a plugin conflict... Don't have to mess with the health scale at all.

[rough drift]

no

it needs to be a url

[charred blaze]

so cant i change title of it?

:<

[rough drift]

the client downloads it

[old sail]

Just created a direct download link and it worked

[lost matrix]

Ill do it in nms first and then ill see if it is even possible. If yes then ill see how to approach this using ProtocolLib

[hidden kestrel]

I'm still seeking potential solutions to this, should there be any takers 😁

[charred blaze]

ok. what is nms

[hidden kestrel]

Okok I fixed the part with the spawn location. Still seeking an event for entering the fountain portal though??

[golden turret]

is there a way to simulate the EntityDamageByEntityEvent to get the final damage?

[ivory sleet]

Technically you could call it manually altho that could be dangerous

[maiden thicket]

net.minecraft.server

the internals

[red sedge]

entity.getAttribute(Attribute.GENERIC_MAX_HEALTH).setBaseValue(entity.getAttribute(Attribute.GENERIC_MAX_HEALTH).getBaseValue() * 5);
why doesnt this work?

like the health doesnt change

[ivory sleet]

believe you need to update it manually perhaps?

(basically use setHealth as well subsequently (if its higher))

[red sedge]

Oh

I also need to set health?

i guess it makes sense lol

[sterile token]

How i can fix the issue between Mongo codec and shity Location object?

[sterile token]

Im exausted because shity location doesnt use native types like double, int, it uses Double

[quiet ice]

Yeah, event constructors are not public API

For whatever reason

[hexed rover]

Hey, is this just some inaccuracies with System.currentTimeMillis() or is the join even on the 2nd server actually calling before the quit event on the 1st server, when switching servers on a bungeecord?

I'm essentially just trying to figure out what the best way and event would be to save and load data again inbetween server switching, AsyncPlayerPreLoginEvent wouldve been my preferred option as it makes the other stuff wait while async loading the data, but that seems to call way before the quitevent, which kind of makes sense.
Now back then without thinking about it i had a redis - sql setup which was saving data to redis on quit and loading it on asyncplayerpreloginevent again but according to this logic, the data loaded from redis on asyncplayerprelogin event shouldnt have been the most up to date one, but it always was

[echo basalt]

redis has a better latency than mysql

like

it's faster

[sterile token]

OH lmao for one second i read redis is slower

😂

[hexed rover]

Yea i know that, that was the entire point of that setup back then, but if we're looking at this, the quit event is called after the asyncplayerprelogin event, which does make sense

[quiet ice]

Yep - join is called before quit

[hexed rover]

so how would the data have been up to date?

[echo basalt]

prelogin -> fetch data -> quit -> save data -> fetch data request received -> response

[sterile token]

Catching it

[quiet ice]

I am not too sure if the PlayerJoinEvent is called after quit though

[quiet ice]

catching what?

[hexed rover]

what i did back then was loading the data on asynclogin and saving it to redis on quit
when switching inbetween servers like this, it was working without any issues.
But since quit is called after asynclogin this doesnt quite make sense to me anymore

[echo basalt]

latency

I have a data syncing plugin that does that redis + mysql stuff

[sterile token]

Proxy:

1. Join -> Load data
2. Redis cache
3. Quit -> Save data

[hexed rover]

Is there any recommended event to save/load the data in then? cause im honestly not confident in using any of the Quit/Login/Join events if quit is seemingly called after the joining ones

[echo basalt]

autosaves and caching data on other servers is ideal

[sterile token]

Yeah its really diff and mostly when should be all up to update on less time posible

[echo basalt]

I have a cache that makes it so that all the connected servers receive the data and hold it for 30 seconds, so that it's pre-loaded when the player joins

[hexed rover]

but when do they hold them for 30 seconds?

when do they receive the data?

[echo basalt]

Whenever I save any data

including autosaves

[sterile token]

I forward recommend something like Redis cache and pub-sub for doing that

[hexed rover]

hm, issue with that is low key, i would most likely only ever be saving any data to redis like every minute for redundancy, and when someone leaves after a save has been made but inbetween their data has already changed again, then it would still be off

[sterile token]

No because you can use pub-sub for pushing updates

[echo basalt]

Save operation:

send packet to all servers saying: <player uuid> is saving
save data
send packet to all servers saying: <player uuid> is done saving, followed by the saved data

Load operation:

Check if the uuid is still saving, if so, await for the following packet and use its data
If it's not being saved, safely fetch

If we're still fetching, and receive the save packet, we cancel the fetch operation and go back to load step 1

https://github.com/IllusionTheDev/DataSync/blob/master/src/main/java/me/illusion/datasync/handler/PacketCache.java

[sterile token]

Oh lol never seem that

[echo basalt]

It's kinda wonky but it accounts for delays and all

[dim palm]

Hello, i have a question, im recoding my StaffMode plugin Items, i want create a class for all strings, i want to automatic add the lore in the same class without creating a "public method" (Im new to java and spigot api)

[hexed rover]

This all seems good and all, but i still wonder what happens when a save has happened, the other servers cache the data
the data on the server the player is on changes, now he switches servers, and the data on the other servers would be wrong, no?

[echo basalt]

the autosave isn't the only save operation

[tall dragon]

ive done something similar before with a standalone system, servers can "loan" playerdata from the system. where other servers can only get it when the system has it back

[hexed rover]

when do you save then

[echo basalt]

onPlayerQuit

and on an autosave every like 5 mins or something

[hexed rover]

yea, but as we learned quit is called after asyncpreloginevent

apparently

[charred blaze]

aaa

[echo basalt]

ehh

[sterile token]

No no

[echo basalt]

I'm doing PlayerJoinEvent instead of prelogin

prelogin can still be cancelled

[hexed rover]

yea i can account for the cancel tho, thats not really the issue, but i need some of my data on join already

[echo basalt]

then uhh

timestamp everything

your problem is that you're doing it too fast

You can delay it a bit on the proxy side or something to account for that delay

[eternal night]

or you delay moving them from server a to server b on server a until write is done 🤔 not like they can get to server b without server a initializing it

[hexed rover]

since asyncplayerpreloginevent is called before quit tho, the save wont be happening until the preloginevent is done

[eternal night]

Well you don't save on quit

[hexed rover]

when would i save then

[echo basalt]

before moving

[eternal night]

you save when server a initializes a move to server b

[hexed rover]

is there an event for that?

[eternal night]

wherever you start that ?

e.g. if you have a server selection gui

or /leave commands

or whatever

[hexed rover]

I don't, happens when they switch servers using /server or any GUI that might not even be from my plugin

[echo basalt]

usually it's a bungee plugin message

so PluginMessageEvent

[hexed rover]

does /server also call the PluginMessageEvent

[echo basalt]

uhh

[eternal night]

Hmm, I mean PluginMessageEvent is proxyside

[echo basalt]

bruh

add a plugin message listener

[hexed rover]

the only practical idea i could think of to make it "easier" is to save the data to redis everytime a change happens to the data

that would keep it up to date

but would also seem like a bit of waste

[echo basalt]

how to spam database 101

[hexed rover]

yes

[echo basalt]

all of that magic because you can't wait that extra tick

[eternal night]

that is the wrong way around tho. That listener is run on recieve

not on sent

[echo basalt]

fucking hell uh

[hybrid spoke]

lynx

[eternal night]

mhm ?

[hexed rover]

I mean yes and no, I would've tried doing it on login or anywhere else basically, but since the Join according to my timestamps in console is also called before the quit I'm heavily confused on what to really do

[hybrid spoke]

you are pretty familiar with the internals of craftbukkit arent you?

do you know a way how to access the palettedcontainer async?

[eternal night]

on spigot ?

[hybrid spoke]

yup

or to avoid it and still get chunksnapshots async

[eternal night]

Well, I'd give you the "use paper and be happy"

I don't know what spigot does 😅

[hybrid spoke]

meh but thanks

[eternal night]

Yea sorry I cannot help here

paper mangles around the paletted container a bit so eeh

don't think the code looks similar enough

[hybrid spoke]

do you have a reference?

anything i can look at?

[eternal night]

for paper ?

or how to use it on spigot

[hybrid spoke]

how paper handles it and what we could try on spigot

[eternal night]

iirc paper syncronizes the write access to the internal data ? Like synchronized

Where vanilla and spigot used to call a lock / error on double lock

[hybrid spoke]

so we have to take down spigot to do our stuff and then allow it to access it again

got it

[eternal night]

yea, just have your plugin download paper

I presume, you could hack your way into the lock ?

[opal juniper]

now that is geenious

[eternal night]

btw @opal juniper the "accessing paletted from multiple threads" thing, is that on paper ?

[hybrid spoke]

can you elaborate on that a bit more

[opal juniper]

no lol, i didn’t realise that god was running spigot at that point

that’s what you get on spigot

[eternal night]

Ah xD Yea I was looking through paper and was confused 😅

[hybrid spoke]

^^

[opal juniper]

i dev on paper so never encountered this issue lol

[eternal night]

Well, let me open the forbidden texts, my spigot workspace

But yea, the ThreadingDetector is the lock used by the PalettedContainer to basically error on any access from multiple threads

instead you might be able to either completely yeet the lock or replace it with a waiting lock

with a bunch of reflection and a child class of the ThreadingDetector you write yourself

Could also just try to unlock forcefully

[hybrid spoke]

that sounds kinda aids

[eternal night]

it will be

I mean, paper's synchronized will also just forces the thread that wants to write data to wait if the data is already locked

[opal juniper]

get to it god ^^^ :))

[hybrid spoke]

its your lib ¯_(ツ)_/¯

[opal juniper]

:))

[eternal night]

I mean, in the end you can also just wait on the underlying lock

which might be better anyway

[opal juniper]

should have brought my school provided laptop away with me for the weekend

chrome book

[eternal night]

like, internally it just a Semaphore with a single unit of capacity

Tho

that won't work, minecraft would then error

[opal juniper]

🎉

i think getting rid of the lock is probably a bad idea, so yeah waiting is probs the only way

[eternal night]

Yea, but waiting is kind of fucked too

[tardy delta]

think i finished it

[eternal night]

you'd have to lock it manually again while you write off main thread

but if that shit is locked while minecraft wants to write, that shit will blow up again

[opal juniper]

we aren’t writing

only reading

[hybrid spoke]

but all of that isnt guaranteed to work, isnt it?

[golden turret]

guys, i need a help in this logic

[eternal night]

oh

[golden turret]

i thought in using recursive

reveal(x - 1, y)

etc

but it throws StackOverflow

[eternal night]

you would want to not reveal neighbours if your field is already revealed

else your fields keep revealing each other

[golden turret]

oh yea

i have that info

[sterile token]

org.bson.codecs.configuration.CodecConfigurationException: Property 'x' in Vector, has differing data types: TypeData{type=Integer} and TypeData{type=Double}.

Please what i can do?

[golden turret]

i will try again

[vague drift]

Hi, has anyone here used Kyori? I can't find a solution for this...

example
String text = "&a&lExample text <gradient:#5e4fa2:#f79459>with gradient</gradient>" TextComponent serialized_message = LegacyComponentSerializer.legacyAmpersand().deserialize(text);
and send to player audience.sendMessage(serialized_message);
the problem is that it encodes the legacy text but doesn't send the gradient so I need to pass that to the MiniMessage.miniMessage()... but minimessage only accepts String as input.
How can I pass TextComponent (inherited from legacy) to MiniMessage (also encoding <> tags)?

[sterile token]

Any recommendation?? Because i have been with this hsit more than 1h

[sterile token]

Paper has specific support discord

[agile anvil]

Code ?

[sterile token]

Yeah 1 sec

[golden turret]

thank you!!!!!

[eternal night]

👍

[sterile token]

https://paste.md-5.net/coxevovazo.javaHere here you have

[sterile token]

Please let me know if you understand what happening

Here is the exception:

org.bson.codecs.configuration.CodecConfigurationException: Property 'x' in Vector, has differing data types: TypeData{type=Integer} and TypeData{type=Double}.```

[golden turret]

that is from bukkit?

[agile anvil]

That's also my question. If not please show us your class

[sterile token]

Yeah

Im having troubles with bukkit one

[golden turret]

hmm

[sterile token]

Also wait i will see the location class

[golden turret]

how are you reading the vector?

[sterile token]

Maybe its using the java one

Im not using vector

I explain

[golden turret]

you are

but

maybe

you are reading 1 instead of 1.0

[sterile token]

My Claim class, contains locations object references. So if i dont add Location to codec then i get an issue "that a codec for location is not found"

[agile anvil]

Let us see everywhere there is a variable 'x'

[sterile token]

So once i add Location to codec i started to get tha exception

Maybe Location doesnt use bukkit Vector so that the issue

🤔

I ill check that now

[wild reef]

Hey guys, is there a way to check if a block for example is able to drop xp or a mob? For example I would iterate through a list of entities or blocks and would be able to check if they would drop xp when I kill/break them?

[sterile token]

I think you can use xp drop event

[eternal oxide]

Location uses Bukkit Vector but it doesn;t store any Vector. The error is not from Location

unless you used a Vector in your TypeAdapter

[sterile token]

Elgarl i dont know what happening

Because i never use Vector

[eternal oxide]

?paste your type adapter for Location

[undone axle]

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

[sterile token]

TypeAdaptor

?

He

Im using Mongo codec

Explain that please

[eternal oxide]

mongo 😦

[sterile token]

Yes

[wild reef]

how is the class exactly called? Can't find it rn

[sterile token]

I dont know if it exists i didnt find too

[eternal oxide]

I've not used Mongo, but I do know for Gson to serialize Locations it requires a TypeAdapter

[sterile token]

Yeah but im neither using Gson

[eternal oxide]

Mongo uses Gson

[sterile token]

But im using Mongo codec!!

[eternal oxide]

org.bson.codecs.configuration.CodecConfigurationException: Property 'x' in Vector, has differing data types

[sterile token]

BSON != GSON tho

[eternal oxide]

ah I read wrong, sorry

[sterile token]

Na dont worry

I just trying to discover what happens

Because i never using vector lmao

Claim contains references:
-> Location
-> Cuboid

Cuboid contains references:
-> Location (Corner 1)
-> Location (Corner 2)

So im really 🤡

[wild reef]

I don't think it does..

[eternal oxide]

?paste your two clases

[undone axle]

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

[sterile token]

Have you checked? Because im never using Vector on my pl

Claim contains references:
-> Location
-> Cuboid

Cuboid contains references:
-> Location (Corner 1)
-> Location (Corner 2)

[snow compass]

Seams you can´t even have missing classes Inside that class you shall use #deserialize(). I think it have to do with the methods bukkit use to find #deserialize() method inside the class. #serialize() don´t have same issue.

Of some reason, don´t know if they add some ignore to that method so you don´t get java.lang.NoClassDefFoundError if you add classes some not exist in older minecraft versions in that method, because if you add other method in the class (you implement ConfigurationSerializable) you directly get java.lang.NoClassDefFoundError (don´t test if order of method matter).

[sterile token]

Allright

[eternal oxide]

Is this error when you make a query to Mongo?

[sterile token]

Once it try to apply the codec to the driver

[wild reef]

So anyone got an idea on that?

[eternal oxide]

You'll need an expert with Mongo I guess

[crimson terrace]

is your question how to check whether killing a mob or breaking a block would drop xp?

[hidden kestrel]

How do I set a player's sleep ticks so that the night doesn't skip??

[golden turret]

🤔

what is happening

[sterile token]

That the error Elgarl

[lost matrix]

If you save a vector, make sure to use doubles only. Done.

[sterile token]

Smile

Im not using Vector

That the issue

[eternal oxide]

what is Main.java:38?

[lost matrix]

Transitively you do

[sterile token]

StorageManager#open()

[sterile token]

So what i can do?

[eternal oxide]

is that all?

[sterile token]

😂

[wild reef]

yea that's the question

[eternal oxide]

that can;t be the whole line

[sterile token]

Smile im just keeping track of Location on my Claim class

So how i can solve it?

[lost matrix]

Show your code

[wild reef]

like besides using entitydeathevent and bockbreak, some attribute to check. Like if material X or itemstack X would be able to drop xp

[sterile token]

Which? StorageManager? Claim?

[lost matrix]

Yes

First the data

[sterile token]

Data?

The claim right?

[lost matrix]

Every entity drops exp.
For blocks i think you would need to use nms.
I dont know of any property that is exposed by the spigot api.

[sterile token]

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

There you have smile the manager and the claim

[lost matrix]

Show Cuboid

[sterile token]

Allright

[wild reef]

but are u sure there is something with nms? otherwise I would need to make some static list where all of them are placed

[sterile token]

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

[lost matrix]

Yes im sure this can be looked up in nms.

[lost matrix]

Why dont you use spigots BoundingBox?

[sterile token]

Its for support reasons from 1.12x to lastest

Im just trying to understand why im getting that eception

[eternal oxide]

which line is StorageManager.java:33

[sterile token]

CodecProvider provider = PojoCodecProvider.builder().automatic(true).register(Vector.class, Location.class, Cuboid.class).build();

[lost matrix]

Ah PS: Location can not be serialized by the PojoCodec from MongoDB.
It contains a Reference<World> world which cant be serialized easily.

[eternal oxide]

thats different to what you just pasted

[sterile token]

I also try adding Vector to codec because i thought that was the caused

[eternal oxide]

ah ok

you definitely use teh Bukkit vector there?

[sterile token]

Yes

Lmao shity mongo

[ornate patio]

what is a bounding box?

[sterile token]

Idk why it doesnt works like Mongoose :mad:

[sterile token]

Is a class for working with cuboid areas and many things

[ornate patio]

so will block.getBoundingBox().getHeight() > 1 return true for something like a fence?

[lost matrix]

yes

i think so

[ornate patio]

alright

[sterile token]

Smile so what i can do?

:sad:

[lost matrix]

implement a simple codec for Location

[sterile token]

didnt already do it? PS

[wild reef]

Uhm any particular site for checking how this could be done / or could u tell me if you have any clue about it, which class this could be used on?

[lost matrix]

No you are trying to generate a pojo codec for Location. That wont work.

[sterile token]

Ohh ok

So i need to implement a pojo for location

Allr

[lost matrix]

Already searching. I think i got something. One moment.

[wild reef]

thank you

[sterile token]

Simile do you have lot of experience with mongo?

Smile also what do you mean by a location codec?

[lost matrix]

This is really hard. The dropped experience is dependant on the ItemStack that is being used to break the Block.
You wont get any if you break the Block with silk touch for example.

[lost matrix]

yes

[lost matrix]

codecs are used for (de)serialization

[sterile token]

Yeah

So how i would register a pojo?

[lost matrix]

Do you want to predict the experience of a Block or of a Material?

[lost matrix]

Like you did. But Location is not a pojo,

[crimson terrace]

its possible to set the experience in the BlockBreakEvent, so in case other plugins are messing with exp for entities and blocks it would be hard to predict

[lost matrix]

For Location you need to implement

public class LocationCodec implements Codec<Location>

And register an instance of it.

Im this far:

But there is no easy way to get this unless you specify more information

[ornate patio]

@lost matrix For the blockfinder, do I instantiate a new HorseBlockFinder every time the horse moves?

[agile anvil]

Did you tried getting the NMS block ? In previous versions I know the existence of a getExpDrop

[sterile token]

Oh as i thought

[lost matrix]

Nope. You constantly schedule N steps/tick until you either hit SUCCESS or FAILURE.
Afterwards you instantiate a new HorseBlockFinder.
But this finder should probably be inside a goal. If the Horse is already moving to a
source or doing something else then you dont need to tick the finder.

[ornate patio]

yeah its inside a goal

[lost matrix]

So on SUCCESS -> goal should change to moving. On FAILURE -> just instantiate a new BlockFinder.

[ornate patio]

alright

[lost matrix]

There are a lot of ways you can achieve this. Up to you.

[ornate patio]

oh ok yeah i get it now

[lost matrix]

Yes thats the nms block.

getExpDrop(BlockState iblockdata, ServerLevel worldserver, BlockPos blockposition, ItemStack itemstack)

And as stated: You would need to specify more infos to get the exp.

[agile anvil]

Oh my bad. nvm

[sterile token]

Is there a big diff between Location#getX() and LocatioN#getBlockX()?

[eternal oxide]

double and int

[sterile token]

Oh ok

[sterile token]

Something like this?

public class LocationPojo implements Codec<Location> {

This is not a Pojo.
Pojo mean Plain old java object and refers to a very simple
class that only contains primitives and Strings.

What you just wrote is a Codec. So LocationCodec would be the right name.

[sterile token]

Allright

But is it okay?

I cannot find info about this specific

[lost matrix]

Also: You need to start with beginObject and end with endObject.

[sterile token]

Okay

[silver pulsar]

how do you deconnect a variable form a file configuration.
public static List<List<Object>> oreList = new ArrayList<>();
oreList = FileHandeler.getFile().getObject("oreTypes", oreList.getClass());
the problem is when im editing oreList it also edits the file.

[sterile token]

I didnt understand that

[mighty pier]

how do i use unicode characters?

[eternal oxide]

?paste

[lost matrix]

  @Override
  public void encode(BsonWriter writer, Location value, EncoderContext encoderContext) {
    writer.writeStartDocument();

Hi, little question, there is my code ```@Override

    Player p = (Player) sender;

    String nickname;

    if (cmd.getName().equalsIgnoreCase("name")){

        changeName(p, args);
        nickname = p.getDisplayName();

        if (dataConfig.contains("player." + p.getUniqueId().toString() + ".nickname")){
            nickname = dataConfig.getString("players." + p.getUniqueId().toString() + ".nickname");
        }
        dataConfig.set("player." + p.getUniqueId().toString() + ".nickname", nickname);
        saveConfig();

        return true;

Hi, I'm sorry to disturb for something who look stupid for me but I wanted to know how I can make my plugin available for version who go to 1.8 to 1.19

[mighty pier]

make 2 chars?

what that mean

[eternal oxide]

line 13, 51 and 59, 72

[lost matrix]

Your yml is absolutely fked. You should never end up with a List<Object> where each element is of a different type. Thats horrible.

In my case that methods doesnt exists

I dont know why

whatever is appropriate for Bson

[sterile token]

No understand

[lost matrix]

No i mean that you can literally just fill in the unicode char: '♥' '🔥' '👑'

it just converts to unicode3

If you want the dirty, hacky way: Just shallow copy your stuff into a new List.

  public List<List<Object>> copyOf(List<List<Object>> original) {
    List<List<Object>> cloned = new ArrayList<>();
    for(List<Object> subList : original) {
      List<Object> clonedSubList = new ArrayList<>(subList);
      cloned.add(clonedSubList);
    }
    return cloned;
  }

But that is literally so fking unclean its not even funny.

thx

does anyone know how to apply another mobs AI to a mob

e.g. a zombie to a regular villager

[wild reef]

Sorry wasn't there for some time. I want to basically just check if the block can drop xp, for example it would be enough to say like: stone doesn't drop xp, a coal ore instead could drop xp

[lost matrix]

Just write a set of materials and throw those in:

[wild reef]

alright so make an own list which would need to be updated manually correct?

[eternal oxide]

For what reason do you want to know if a block can drop exp?

[wild reef]

I need all these blocks in a list. So question is if I need to create a static one or if I can generate it through spigot-api / nms just so it's dynamic and not based on a fixed version

[iron glade]

Why a list?

[eternal oxide]

Yes, but for what reason?

Why do you need a List of blocks that can drop exp?

[pastel relic]

how do I check if the plugin folder exists?

[eternal oxide]

plugin.getDataFolder.mkdirs()

or plugin.saveDefaultConfig()

[eternal oxide]

I ask because depending on what you are doing you may not need a List at all

[wild reef]

I have custom amounts of xp for some blocks. To make the check simple I want to check if block X drops xp, if yes I will get the value just from a map where the custom xp for the block would be stored in

[eternal oxide]

There is https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/block/BlockExpEvent.html

[wild reef]

ah alright

thank you

[eternal oxide]

just get the Block there, see if it's in your list, if it is, get the value and set it

[wild reef]

but there is nothing overall right? cause I maybe want to check for stuff like breeding xp as well

[eternal oxide]

No

[pastel relic]

I made a reload command for the config file and i ckeck if the config.yml exists, if not it creates one but if the entire folder is deleted i get an error so i need a way to check if the folder the plugin is in exists and if not again create one.

[kind hatch]

File#exists()

[pastel relic]

I know how to check for the config file

i need to check for the folder thhe config.yml is stored in

[kind hatch]

Use the same method. A file can also be a directory. You can use the additional File#isDirectory() method to check that.

[pastel relic]

something like this?

File pluginFolder = new File(main.getDataFolder());

[kind hatch]

Yep. Then you just check if it exists.

[pastel relic]

okay

[gritty urchin]

How do I apply a mob's AI to another mob

[onyx fjord]

does java have something similar to canvas js?

[lost matrix]

You mean for swing components or for web frontends?

[lost matrix]

Dont use statics at all. Statics should contain constants or singletons. Nothing else. Having public mutable statics like normal maps, set and lists is
a very bad coding style and will lead to fragile code.

[onyx fjord]

i just want to manipulate images

create canvas, set some background, some text all thru code

[kindred valley]

wdym by constants and singletons?

[lost matrix]

You can do all of this through awt.

    String imagePath = "path/to/your/image.jpg";
    BufferedImage myPicture = ImageIO.read(new File(imagePath));
    Graphics2D graphics2D = myPicture.createGraphics();
    and so on

[onyx fjord]

😵‍💫

thx

[crimson terrace]

Constants as in a "public static final NamespacedKey CUSTOM_ITEM" kinda thingy

[lost matrix]

Classes of which only one instance is ever created are called singletons.
All you manager classes should be singletons.

[crimson terrace]

or private static final

[lost matrix]

This is a constant, not a singleton.

[crimson terrace]

they did also ask about constants

ew

[lost matrix]

The max possible health on default is 2048

You can increase this in the spigot.yml

[gritty urchin]

Health must be between 0 and 100.0, but was 150.0. (attribute base value: 100.0)

[lost matrix]

What version are you on?

[gritty urchin]

one you dont like

1.8.8

[lost matrix]

Well... too bad i guess.

Did they already have attributes back then? I thought you would have to use nms for that.

[onyx fjord]

no

they didnt

at least i think so

[gritty urchin]

how do I set health in NMS

[onyx fjord]

why do you do this to yourself

[gritty urchin]

not my choice

someone else wants 1.8.8

cant see any other way to do it

[lost matrix]

EntityLiving nmsEntity = ((CraftLivingEntity) entity).getHandle()
Then see what methods you got there.

[gritty urchin]

thanks mate

[hybrid spoke]

you need NMS to set the health in 1.8.8?

[gritty urchin]

above 100

yes

[pastel relic]

btw, weird thing with this is that it created the folder in the plugins folder but it also creates a folder with the same name in that folder it creates

anyone know why?

[onyx fjord]

arent plugin folders auto generated once theres some config file?

[pastel relic]

they are

[pastel relic]

read this ^^

[crimson terrace]

well you did call the file "DeluxeWelcomer"

[pastel relic]

and?

[crimson terrace]

is that the name of your plugin?

[pastel relic]

it is

[hybrid spoke]

you are creating a folder inside your datafolder, which is named like your plugin

[crimson terrace]

welp

[hybrid spoke]

the datafolder is not the plugins folder

its the plugins/YourPlugin

at least the plugin you are calling getDataFolder from

[crimson terrace]

first is the folder the file is in, then is the file name in the File constructor

[pastel relic]

yes but i need to create that folder if it doesnt exist

[crimson terrace]

mkdirs()

that does what you want

[lost matrix]

      File pluginFolder = plugin.getDataFolder();
      File subFolder = new File(pluginFolder + File.separator + "subFolder");
      if(!subFolder.exists()) {
          subFolder.mkdirs();
      }
      File file = new File(subFolder, "data.yml");
      // save to file here

[crimson terrace]

mkdirs() creates all folders needed for the requested path

[pastel relic]

ok but this will create a folder inside plugins/MyPlugin/NewFolder, right?

[lost matrix]

Yes

[pastel relic]

I dont want it to do that though

[crimson terrace]

then tell us what exactly you want to do please, I am also confused

[pastel relic]

i need to create the folder for the plugin where the plugin config is

[quaint mantle]

in the plugin folder?

[eternal oxide]

new File(getDataFolder(), "subFolder")

[quaint mantle]

that should be where the config is

[crimson terrace]

that gets auto created when making a config afaik

[pastel relic]

yes, in the plugins folder

[pastel relic]

yes but OMFG

[quaint mantle]

now im confused and i just want help with my question 😵

[pastel relic]

read this

[quaint mantle]

i feel like maybe learn a little more about java file stuff idk

[pastel relic]

ur not helping

[quaint mantle]

¯_(ツ)_/¯

[crimson terrace]

the getDataFolder() is the folder youre looking for. thats where the config file will be. I think youve been trying to go one level too deep

[quaint mantle]

^

[lost matrix]

Do you want

/plugins
    /YourPlugin
       config.yml
       somedata.yml

Or do you want

/plugins
    /YourPlugin
       config.yml
       /CustomData
          somedata.yml

[quaint mantle]

your config should be made there

[eternal oxide]

If your config gets deleted just call saveDefaultConfig() It will create teh folder if its missing and save your default config from the jar

[quaint mantle]

this

[pastel relic]

first one

[quaint mantle]

then your question was already answered

[pastel relic]

the default folder that gets created with your plugin that contains the config files

[quaint mantle]

with this

[lost matrix]

      File pluginFolder = plugin.getDataFolder();
      if(!pluginFolder.exists()) {
        pluginFolder.mkdir();
      }
      File file = new File(pluginFolder, "data.yml");
      // save to file here

[quaint mantle]

^

[crimson terrace]

^

[lost matrix]

Unless you have a default config.yml because then you can just call saveDefaultConfig() and it will create the plugin folder.

anticheat question w/ speed check
how should i use Material#getSlipperiness() so i dont have to cancel the check entirely if the player is on ice, or a block that messes with the default friction?

[pastel relic]

finaly, tysm

[lost matrix]

Does your anti cheat have a heuristic, statistical or reinforcement learned approach?

[quaint mantle]

it checks if they haven't done stuff that would make their movements normal and then flags them

so if they haven¨t jumped recently, or glided, etc. nto inside vehicle but they are in the air and their Y isn't going down

then fly (theres more than that, i simplified that a lot)

[lost matrix]

So statistical. This just means you need to find out how much faster they are on slippery surfaces and increase the threshold accordingly.

[quaint mantle]

thank u btw bc i didnt actually inderstand what u meant lol

in that case, should i determine threshold on event

or get a threshold from sprinting, and adjust accordingly if they have a speed potion, etc.

[lost matrix]

Wait... you are writing an anti cheat on event level?

[quaint mantle]

no it has handle()

handle(PlayerMoveEvent e)

if(booleans){ return; }

player.flag(check)

it seems to work?

im willing to improve it beyond 1000% if anyone has better ideas than just a handle() method

[lost matrix]

You wont come far with this approach...
A good anti cheat needs a very deep understanding of the protocol it is currently on and handle
the packet transactions between server and client. Relying on events wont cut it for many many checks.

[quaint mantle]

yeaah, i'm adding packets for some checks that rely on them (blink, some exploits, teleport) but for now, Fly seems to flag awesomely and same with my current Speed check.. it's also for 1.19 and im not sure why but packets seem to have gotten vague after 1.13

should ibother making an anticheat for 1.19 or will Microsoft block hacked clients too because they want control? 🤣

[lost matrix]

No they wont. They really couldnt care less. They rather impose vaguely defined speech constraints.

[quaint mantle]

😭

[agile anvil]

I got too much with anticheat... I prefer way more to rely on the other players to detect someone cheating and having mods

(while your server is < 150 players it's ok)

But I had really good time making anticheats back in 1.8

[lost matrix]

Every server with a half decent anti cheat i worked with had a dedicated team of at least 2 devs that did nothing else but
perfect their anti cheat. Its quite the task and you need a ton of knowledge beyond minecraft/spigot as well.

[quaint mantle]

well thanks for the wisdom and advice because it does mean a lot and it helps, i think i'll try out some values while sprinting with various effects to see if i can make up some thresholds and mess around with .getSlipperiness()

[subtle folio]

This is the most craziest thing

Maybe caused of git plugin?

[quaint mantle]

Is there a way to copy the config and save it in a different file path ?

For example:

File file = new File("path goes here");
YamlConfiguration config = YamlConfiguration.loadConfiguration(file);```

[sterile token]

If you mean copy you can get the parent file

[eternal oxide]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/plugin/java/JavaPlugin.html#getResource(java.lang.String) and save

you can get any resource in you jar

[quaint mantle]

Correct, copy the content inside of it.

Inside of the resources/config.yml

[serene fractal]

Path sourceDirectory = Paths.get(config location);
Path targetDirectory = Paths.get(whereto location);
Files.copy(sourceDirectory, targetDirectory);

got that from a quick google search

btw

[quiet ice]

that will not work

Files.copy does not copy directories

You need to walk the tree for that

[serene fractal]

what are you on about

[quiet ice]

Now that I think about it it could also have been an issue with Files#move that I had in mind

[serene fractal]

yeahhhhhh idk what ur on about man

[quiet ice]

Throws:
[...]
DirectoryNotEmptyException - the REPLACE_EXISTING option is specified but the file cannot be replaced because it is a non-empty directory (optional specific exception)

Got a little bit confused with the REPLACE_EXISTING option

[serene fractal]

ah alright

[quiet ice]

Though I believe it throws a similar exception if you try to move a directory into something that does not yet exist or something

But whatever

[serene fractal]

could just check if the file exists in the target directory, if it not then create. to counter that but sure.

• it doesn't throw the exception if the file doesn't exist, it just simply "copies".

although I am exception handling, so you are partly correct

[serene fractal]

    public static void copyFile(String from, String to) throws IOException{ Path src = Paths.get(from); Path dest = Paths.get(to); Files.copy(src, dest); }

[quiet ice]

Ah I now get why you were confused

I thought you copied entire folders, but apparently you just copied a file-file

[serene fractal]

yea, as TheBigDonggggggg only said the config.

not the whole folder.

[lime moat]

How could I use something similar to if (target.getAllowFlight()) { but using the Invulnerable method? Player#setInvulnerable()

[lost matrix]

Player#isInvulnerable()

[lime moat]

Oh, thank you!

[ornate patio]

how hard is this to implement:

the horse can't seem to figure out how through the opening in the wall

instead it just stares at the wall indefinitely

it's trying to reach the feeder (brewing stand) on the right

[lost matrix]

Does the BlockFinder find the block?

[ornate patio]

yes, if i cover up the hole in the wall the horse actually walks away freely

[lost matrix]

So its a problem with the vanilla pathfinder you are using?

[ornate patio]

the thing is while the blockfinder can successfully detect whether a target is reachable, it doesn't really help the horse find its way

[ornate patio]

yes i'd assume so

[lime moat]

Another thing, how would I set the durability of an item?

I see setDurability is deprecated

[lost matrix]

You cast the ItemMeta to Damageable (be careful because there are two different ones)
and set the damage.

Make sure to set the ItemMeta back on the ItemStack afterwards.

[ornate patio]

i've noticed that the vanilla pathfinding to entities is actually a lot smarter compared to blocks

I have a pathfinder goal which makes horses attack other horses, which uses the vanilla pathfinder

and it knows how to walk around walls and everything to reach the target

do you think it might be a good idea to spawn a marker entity on the target block?

[mortal hare]

man its been almost 3 days but I still cant believe technoblade is gone

its not as if I was a fan of him or something

its just that deadly feeling that such a disease can end person's life so quickly

i never really watched him either but i had mad respect for him

ok I've noticed the blockfinder actually returns a success here

but I figured out why

if I make the wall 1 block higher, it returns failure

[hidden kestrel]

I'm getting a NoSuchMethodError when using Advancement#getDisplay() - anybody know why??

[ornate patio]

the finder searches the block thats above, which passes all the checks in the filter

[sacred mountain]

wrong channel

[lost matrix]

Same here. I didnt really watch his videos. Only occasionally. Its a bit weird...

[sterile token]

agree with you

[hidden kestrel]

Anybody know before my question gets buried under talks about our mortality ??

[mortal hare]

well maybe you're using wrong api version

inside gradle or maven

or you're running older version of minecraft server

[hidden kestrel]

It compiles fine, and I'm using the latest version of paper

[mortal hare]

can you post the whole stack trace via ?paste ?

Yeah one minute

[quaint mantle]

I wanted to copy it from the Resources file inside the plugin

Hello, I have this code for a wild command: https://paste.pythondiscord.com/ukiyasiviw

I'm trying to make the Y value be 1 than the safe location and also have the X and Z value be 0.5 more as I spawn inside the ground in the center of 4 blocks right now.

[mortal hare]

can you show your code snippet

CommunityEventManager line 93

[hidden kestrel]

    @EventHandler
    public void onAdvancement(PlayerAdvancementDoneEvent e) {
        for(Entity loopPlayer : e.getPlayer().getWorld().getPlayers()) {
            if(e.getAdvancement().getDisplay().getType() == AdvancementDisplayType.TASK || e.getAdvancement().getDisplay().getType() == AdvancementDisplayType.GOAL) {
                loopPlayer.sendMessage(ChatColor.of("#ffad1f") + "- " + ChatColor.of("#ffec42") + e.getPlayer() + " has completed " + ChatColor.of("#ffad1f") + e.getAdvancement().getDisplay().getTitle());
            } else if(e.getAdvancement().getDisplay().getType() == AdvancementDisplayType.CHALLENGE) {  // line 93
                loopPlayer.sendMessage(ChatColor.of("#b22deb") + "- " + ChatColor.of("#ff88ff") + e.getPlayer() + " has completed " + ChatColor.of("#b22deb") + e.getAdvancement().getDisplay().getTitle());
            }
        }
    }

I recommend going to the Paper discord or trying with Spigot

[quaint mantle]

RankLoader.config.save("" + GioxRanks.getPlugin().getResource("asdf"));```

Would this save the asdf.yml copied from the resources/?

[mortal hare]

🤔 i see nothing wrong here

[hidden kestrel]

yeah i guess it could probs be a paper bug??

[hidden kestrel]

I know right

[mortal hare]

it seems like a linking issue

[hidden kestrel]

Wdym a linking issue

[mortal hare]

from paper's side

[hidden kestrel]

Owh

[mortal hare]

Your plugin tries to access method which does not exist at runtime

but it should

since its paper bukkit api method

[sterile token]

Its possible to check a boolean condtion uisng Optional but when the result is true run something, if false run another thing

[mortal hare]

Maybe Predicate functional interface?

[sterile token]

Allright

Can i get an example

[ornate patio]

i have a question on how to implement the logic of something

[sterile token]

?as

ask

?status

[mortal hare]

Predicate<String> predicate = (string) -> {
  return string.equalsIgnoreCase("yes") ? true : false;
};
boolean test = predicate.test("yes");
boolean testFalse = predicate.test("noooo");

im not sure if syntax is correct but that's how predicates work

they're mini blocks of code which can be dynamically allocated to test some condition

[sterile token]

Dovidas i need the thing for my menu api, so if the handler contains the player -> open the menu if not stop execution

[ornate patio]

I'm trying to make a function to see whether a block is able to be stood on given only the Block object of the target (in this case, the diamond block)

on the right, it is possible to stand on top of the diamond block. So the function should return true

on the left, it is not possible to stand on top of the diamong block, so the function should return false

How would I go about doing this? I thought it was simple at first but its actually a lot hard than anticipated

[sterile token]

What the heck are you building?

Looks like you are coding custom things

[hybrid spoke]

what do you have so far

[ornate patio]

its just a testing platform

[sterile token]

Not much

I just want to optimize it a bit more

[opal juniper]

is it just me or is there no point to this ternary

[mortal hare]

there's no point

you can even remove code block braces and return in this case

[opal juniper]

:)

[sterile token]

So its possible to do that code better?

[hybrid spoke]

except for the namings, what do you imagine?

[mortal hare]

what about (abs(block's y position) - abs(player's y position)) <= 1 block

[sterile token]

Something more profesional

[hybrid spoke]

we would need more context for that

more code

[ornate patio]

" given only the Block object"

[hybrid spoke]

and with that, what is "professional" for you?

[mortal hare]

how would you then know if player can jump on it

if you dont know its location

[ornate patio]

hmm

well

this is gonna be much harder to implement than i thought

[kind hatch]

Doesn't the Block object have a #getLocation() method?

[mortal hare]

in my opinion without knowing player's coords you cant know if you can stand on it

unless you're comparing blocks

[kind hatch]

I beg to differ. You could figure it out, it just depends on your criteria.

[sterile token]

Using Optional, Predicate

[hybrid spoke]

well, "can stand on it" - do you want to know if there is any block in the way on the top or if the block is just a regular one you can stand on?

[hybrid spoke]

that doesn't make it professional. you just want to have something cool-looking. overengineering. you dont need those in this context

[mortal hare]

i would just create method which compares that block location to the anchor location you specify in the method args

[sterile token]

Allright

so its not neccesary as you said

So its just me that want something well look

[hybrid spoke]

yes

[sterile token]

Thanks

[ornate patio]

yeah but getting that other location will be difficult

[mortal hare]

is it possible to apply generic types to fields

without applying it to class level

[kind hatch]

Would it though? You can get the world object from the block and use that to get other locations.

[ornate patio]

its this pathfinding thing im working on

[mortal hare]

then just store block locations

[ornate patio]

it'll just make it a pain

[mortal hare]

if you're doing pathfinding you will still have second location which defines current pathfind location

[ornate patio]

its just the way its set up right now makes it difficult

[mortal hare]

go architectural refactoring go

[sinful rapids]

                        if (isDouble(args[1])) {

                        }

How do I check if args1 is an integer?

[mortal hare]

Integer.valueof()? or Integer.parseInt() ?

i might be wrong

its out of my memory

[sinful rapids]

if Integer.valueof?

[mortal hare]

Integer.parseInt(args[1])

https://www.freecodecamp.org/news/java-string-to-int-how-to-convert-a-string-to-an-integer/

If the string does not contain a valid integer then it will throw a NumberFormatException.

Integer.parseInt()

try {
  Integer.parseInt(args[1]);
} catch (NumberFormatException exception) {
    
  // If this code block executes, then its not an integer.
  // Handle the error by either printing the stacktrace or sending back the message
}

[sinful rapids]

ok

[lime moat]

I have this code: https://paste.pythondiscord.com/ukiyasiviw

How could I make the findSafeLocation be Y+1 and X/Z +0.5

[quaint mantle]

pythondiscord lol

[lime moat]

lol, I'm a python boi

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

[sterile token]

SpigotMC => Its discord dedicated for minecraft

[lime moat]

xd

[sterile token]

No python support here

Sory man

[lime moat]

'tis not python

[sterile token]

I have a question

Why do you use static methods?

When its recommend to use DI (Dependency Injection)

[lime moat]

I don't really have a good explanation besides for the friend I'm working on this plugin with started that :P

[mortal hare]

is factory class constructing concrete builders a good idea?

[sterile token]

Before start programming on a language you should learn the basics of the language. If not its really diff programming

[mortal hare]

lets say i have a builder implementation that is dependant on the implementation classes i dont want for the client to construct them since it belongs to implementation package

i am decoupling interfaces and implementation as far as I can here

[sterile token]

dovidas

[mortal hare]

?

[sterile token]

They still can do it via Reflection

[mortal hare]

but that's way harder

im trying to encapsulate

to prevent that at least

[lime moat]

Well, what's the benefit of using DI?

[sterile token]

?di

[undone axle]

Guide to dependency injection: https://www.spigotmc.org/wiki/using-dependency-injection/

[mortal hare]

It lets you run tests of your code way much easier

since you dont have any static getters inside your class

[lime moat]

Ah, okay, I use that for literally all of my commands lol

[mortal hare]

also it allows for the client to extend that particular class you're using

[lime moat]

I'll alter my code to make it work with DI then

[mortal hare]

for example to modify the behaviour

it can basically act as a composition

[sterile token]

Also statics methods are heavy to proccess rather than DI

[mortal hare]

I call it plug and play 😄 since it does the same, you plug it, what you're plugging into class, you class will gonna use in runtime

[lime moat]

Ahh, I see

[sterile token]

(Confirm dovidas, maybe im wrong)

[mortal hare]

and by using static getter you're hardcoding that functionality

[lime moat]

Is it quite easy to alter it to be DI or would I need to change a lot?

[mortal hare]

its annoying to deal with DI tho

you need to add the objects you're using inside constructor

and add fields for them to store inside the class

[sterile token]

Do you know menu apis paginated?¡

Im needing diff menus apis that allow pagination for testing pupouses

[mortal hare]

Strategy design pattern is very great example of DI (kinda)

[mortal hare]

SpiGUI iirc

[sterile token]

Allright i wil ltake a look

I have seen many menus apis but they are shity for me

Its like i dont like how they are coded

[sterile token]

LMAOO

Holy shit look that

Sorryforping

[dire marsh]

inventoryframework

[sterile token]

This type of things should be banned from spigot

[dusk flicker]

PaginatedGUI is another one

Prior ver of SpiGui iirc

I use it a lot

[iron glade]

https://github.com/TriumphTeam/triumph-gui

works great

[sterile token]

oh thanks people

[torn oyster]

(bungeecord) how do i get a file in the \resources folder and add it to the plugin's dataFolder

[sterile token]

getResourceAsStream()

You can use it on main plugin class

[torn oyster]

how would i create a duplicate file

[main dew]

Hi I think Packet UseItem can be spoofed. How check it?

How to validate this packet?

and is it possible that a player playing without any modifications without external factors will spoofed this packet?

[mortal hare]

he cant spoof packets if he didnt have any mods on

Vanilla minecraft client doesnt provide you a way to manipulate packets

[main dew]

I know xD

however, can ping cause something to break

[mortal hare]

No matter the ping, vanilla client sends packets correctly

even if gets delayed for the server

the worst case scenario would be that the server handled those packets incorrectly

and desync issues would occur

but that's very rare, unless you use some kind of plugins which manipulate packet handling incorrectly

protocollib (with its dependant plugins), viaversion, protocolsupport etc.

[main dew]

Oke but maybe do you know how validate this packet?

[mortal hare]

NMS ServerGamePacketListener class validates those packets

[main dew]

for modified versions of minecraft

[mortal hare]

do you want to modify protocol of minecraft by supporting mods or what?

[main dew]

I have problem with spoofed packet from modified Minecraft version

my server doesn't check them and it causes undesirable results

@mortal hare could say I'd like to do a little anti-cheat

[vocal cloud]

Well you have to describe the issue and exactly what you think is being done.

[ornate patio]

how do I download the spigot-api jar and input it to jdgui

[buoyant viper]

why do u need it in jdgui @ornate patio

[ornate patio]

trying to decompile and search for keywords in the entire jar

for reverse engineering nms

[buoyant viper]

then ur not gonna get far with spigot-api i reckon

use buildtools and sift through the decompiled output

?bt

[undone axle]

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

[ornate patio]

i have buildtools

wait hold up

[buoyant viper]

look in the work folder

[ornate patio]

net.minecraft isn't here

[buoyant viper]

its almost as if i predicted this would happen 😅

[ornate patio]

so how do i look through entire nms code then?

i do have a built in decompiler in vscode but I can only control-click on existing classes

i wanna search for a specific keyword in the entire project

[buoyant viper]

iirc, run BuildTools with the --remapped argument, and then check ~/.m2/org/spigot/spigot/

[ornate patio]

pretty sure the jar i used is remapped

whats the full command again?

[buoyant viper]

java -jar BuildTools.jar --rev <version> --remapped

the jar youre looking for will be in ur maven local repository

[ornate patio]

where is that

[buoyant viper]

somewhere around this directory

'~' denoting your user home directory

like C:\Users\Username\

or /home/username/

[ornate patio]

is there an env variable for the path

i dont see it

[buoyant viper]

not sure and not on pc to test

[ornate patio]

is it spigot-api-1.18.1-R0.1-20220228.150432-81-shaded.jar?

[buoyant viper]

no

[ornate patio]

spigot-1.18.1.jar?

[buoyant viper]

bingo bongo baby

that should be what ur looking for

[ornate patio]

ahem

[buoyant viper]

oh

uh

wait that wasn't supposed to happen

there is supposed to be a lot more there

[ornate patio]

yeah

[lost matrix]

?bootstrap

[undone axle]

Bootstrap Jar
The main spigot-1.18.jar is now a bootstrap jar which contains all libraries. You cannot directly depend on this jar. You should depend on Spigot/Spigot-API/target/spigot-api-1.18-R0.1-SNAPSHOT-shaded.jar, or the entire contents of the bundler directory from your server, or use a dependency manager such as Maven or Gradle to handle this automatically.

Please read the release notes for further information: https://www.spigotmc.org/threads/9-years-of-spigotmc-spigot-bungeecord-1-18-1-18-1-release.534760/#post-4305163

[buoyant viper]

oh it IS spigot-api shaded?

[lost matrix]

There is no uber jar

[buoyant viper]

trying to find the NMS jar for them

should it not have been something like ~/.m2/<something>/org/spigot/spigot/spigot-<stuff>.jar ?
