ooooh

dem

i was create 2 plugins in 1 pacage

but i was can do this...

what the bukkit derictory? i mean it doesn't look like the icons below

[quaint mantle]

I have not tested code yet I’m just implementing a system’s packet listeners for preventing block breaks and stuff in regions and I don’t want to use the bukkit api

[ripe moat]

didn't work

the version under /ver?

[young knoll]

Idk why you don’t want to use the api but okay

[quaint mantle]

I don’t want anything else to happen before I do my checks

[young knoll]

That’s what event priorities are mainly for

[quaint mantle]

But what if there are other listeners at the lowest

I’d like to prep for those cases if they exist

[young knoll]

Well then they are probably protection plugins too

Or they could just be dumb and using the wrong priority

Anyway idk if cancelling events will inform the client, probably not for most cases

[undone pebble]

Right, could you link the error? It could provide some insight as to why it's not working

[ripe moat]

yes sure

[undone pebble]

Be sure to @ me too otherwise I might miss it

[ripe moat]

i am working on a skin maker with Graphics2D, but i have some problems with drawing the hair. the hair is not geting drawed on to the skin that is chosen at Graphics2D g2d = imageskin.createGraphics(); it also does not work when i change it to this g2d.drawImage(imagehair, 64, 64, null); hope you can help me.

no error in the console

[halcyon hemlock]

There is wiki.vg/Protocol

[young knoll]

It’s not official

Nor is it a guide on NMS

[halcyon hemlock]

It's for mc protocol

Nms is packets basically and it has data on it

[young knoll]

NMS is a lot more than packets

[trim lake]

anyone some idea? I need to change block hardness or just breaking time for block. Best way would be probably get custom block hardness every time when player will start destroying and than calculate the breaking process. Maybe there is some better way to do that? I just used minecraft wiki to calculate that but seems to be wrong or I just made mistakes somewhere. Idk Im geting kinda weird output. I just assume canHarvest means if its a crop but that does not make sense... if its like that, because the efficiency enchant would never be applied. Probably it means something else. Code: https://paste.md-5.net/tasizofizo.java and my output:

[devout kite]

it is intresting that i get the error image == null! when i try to get just the imagehair

[river oracle]

you can't change block hardness you'll ned to spoof this

you can probably just fuck with the BlockDamageEvent iirc its called

and send the damage packet to the player

^ is build into spigot so no need for nms

[trim lake]

If I edit block breking process with NMS I think I can, but I would like to keep the tool mechanics.

[river oracle]

could be wrong but iirc hte only way is spoofing it

then you need to readd efficency and haste manually by runnign the calculations yourself

[trim lake]

I just get inspiration here https://www.spigotmc.org/threads/why-custom-block-breaking-change-block-hardness.531825/ but there is set duration for every block and tool, thats why Im tring to calculate breaking time on my own with changed block hardness.

I just need to get correct calculation idk how thats why Im here xD

googling allready for some time

Or maybe I will just need to set breaking duration on every block for every tool... that sounds like pain xD

[young knoll]

If you modify the block hardness server side it won’t change for the client

[thin iris]

how do i make a triangle

[worldly ingot]

You should probably start with three sides

How so? How do you want to make a triangle? What type of triangle?

[river oracle]

make sure all angles add up to 180 degrees

or pi

[thin iris]

https://tenor.com/view/screaming-demogorgon-stranger-things-scary-monster-gif-26253940

jk i’m trying to cut his face and put it onbthe ground

only rhing i can think of is 5 triangles

like a venus fly trap for players

json

[trim lake]

I will change the whole process of breaking block with packets. Like its on the forum post which I mentioned. So now I need to get correct calculation for block breaking speed/time just something xD

[nova notch]

why would you send this here

[umbral marsh]

How do I see if a falling block and player collide?

[trim lake]

Oke I found something new... canHarvest if you can get drop from the block. For ex. if you are mining obsidian with stone pickaxe this is false. It has nothing to do with crops.

[short pilot]

ah! Of course!

not really a problem yet but just an idea

i want to be able to sync faction like groups to a database back and forth and when the server starts it'll load those factions back into the manager

and when events happen like new creations or a name change, the database will update to reflect that

[mighty mason]

Hi, sorry to repeat myself

But is there any a good way to cancel a Cow milking?

Im currently removing the milk from the player after the PlayerInteractEntity event

But i dont think thats the best way

This is my current code:

if(this.CurrentMilkingCoolDown == 0){
                player.sendMessage("You just milked " + this.Name + ". Cooldown now is: " + this.MilkingCooldown);
                this.CurrentMilkingCoolDown = this.MilkingCooldown;
                player.getInventory().remove(new ItemStack(Material.MILK_BUCKET, 1));
                ItemStack item = this.giveMilkBasedOnQuality();
                player.getInventory().addItem(item);
                this.taskID = Bukkit.getScheduler().scheduleSyncRepeatingTask(ZooFee.getInstance(),
                        this::LowerCooldown,
                        0,
                        20);
            }

Actually, im going to post the whole code for the handler that i got:

    public void onPlayerMilkEvent(Player player, Entity MilkedEntity){
        if(this.entity.equals(MilkedEntity)){
            if(this.Sex.equals(ZooSex.Male)){
                player.sendMessage(ChatUtils.setColorName("&lYou can't milk a &r&9&lMale"));
                player.getInventory().remove(new ItemStack(Material.MILK_BUCKET, 1));
                return;
            }
            if(this.Age.equals(ZooAges.Baby)){
                player.sendMessage(ChatUtils.setColorName("&lYou can't milk a &r&d&lBaby"));
                player.getInventory().remove(new ItemStack(Material.MILK_BUCKET, 1));
                return;
            }
            if(this.CurrentMilkingCoolDown > 0){
                player.getInventory().remove(new ItemStack(Material.MILK_BUCKET, 1));
                player.getInventory().addItem(new ItemStack(Material.BUCKET, 1));
                player.sendMessage("The Cow: " + this.Name + " has been milked already. Cooldown now is: " + this.CurrentMilkingCoolDown);

            }else if(this.CurrentMilkingCoolDown == 0){
                player.sendMessage("You just milked " + this.Name + ". Cooldown now is: " + this.MilkingCooldown);
                this.CurrentMilkingCoolDown = this.MilkingCooldown;
                player.getInventory().remove(new ItemStack(Material.MILK_BUCKET, 1));
                ItemStack item = this.giveMilkBasedOnQuality();
                player.getInventory().addItem(item);
                this.taskID = Bukkit.getScheduler().scheduleSyncRepeatingTask(ZooFee.getInstance(),
                        this::LowerCooldown,
                        0,
                        20);
            }

        }
    }

[wet breach]

Only other event i can think of which probably doesnt get fired for this is the playerfillbucket event

[mighty mason]

Thats the one im trying rn

[wet breach]

Could try it doubt it will work. Otherwise the way you are doing it is the only way

Without resorting to nms of course

[mighty mason]

It actually works!

@EventHandler
    public void onPlayerBucketFill(PlayerBucketFillEvent e)
    {
        System.out.println("Converted");
        if (e.getItemStack().getType() == Material.MILK_BUCKET)
        {
            e.setItemStack(new ItemStack(Material.BUCKET));
            e.getPlayer().updateInventory();
        }
    }

[wraith dragon]

hey so I got it working but I kind of have to give the player the map item itself for it to render properly, do you know any fix?

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

this is myt code rn

[mighty mason]

Ey, Quick Question. I got a Mob that has custom holos that i made. Using the DPC (Data Persistent Container) can i save this mob and the holos and reload it after?

It has thing like right click action, amongst other things

[wet breach]

Oh nice. Maybe someone can update to add more entity related methods instead of just blocks

Glad it worked for you

[umbral marsh]

Can someone help me? How do I detect when a player gets touched by a falling block?

[worldly ingot]

EntityDamageByEntityEvent

There's a cause for FALLING_BLOCK

[mighty mason]

Question; To create custom items that will be use to interact with entitys (Ex: Cow food) is it better to use inheritance from ItemStack or just use the customize the MetaData

[pseudo hazel]

use metadata/pdc

[upper hazel]

how create this?

i dont think map api help here

text in block lol

[lost matrix]

2 ways to achieve this:

• Maps
• Text display entities

[upper hazel]

this is an invisible Map?

I don’t see volume, the text is literally in blocks

[lost matrix]

Probably, if its a newer server then it could be display entities as well

[upper hazel]

1.20.1

[short raptor]

Neither of these work to ban player.. first one throws "nosuchmethod" and second one doesn't even compile as you can see

victim is a Player

red squigglies say "cannot resolve method addban.........."

[slender elbow]

cast to ProfileBanLisy

then addBan

[short raptor]

No such method on this as well

At runtime

Its fine in IDE

intellisense shows it

[slender elbow]

server version?

[short raptor]

1.20.1

[slender elbow]

disregarding the fact you are running paper and this is spigot, you are running a build prior to that method being added

tldr update your server

[short raptor]

Even tho its the same api version?

damn

I will try update

[wraith dragon]

ok to fix this I gave the player an item then ran a task async where I remove the item from their inv

[quaint mantle]

why r u calling fields with upper case first letter

[umbral marsh]

Can someone PLEASE HELPPP

[quaint mantle]

dont ask to ask

just ask

[umbral marsh]

How do I check when a falling block hits a player?

I am dum

And new

Hello?

lmfao peoples just given up

[lilac dagger]

Probably entitydamagebyentity

@umbral marsh

I'm pretty sure falln blocks deal damage

[umbral marsh]

Not all the time

[shadow night]

what's the greatest vertical velocity a player can possibly have in vanilla?

[glad prawn]

then byblock

[umbral marsh]

???

[placid moss]

its probably infinite until server dies

[shadow night]

not what I meant

wait

what's the greatest vertical velocity a player can possibly reach in vanilla?

[glossy venture]

bro WHAT

ithats the thing tho its not

v is like legit some special value or smth

jvm bug?

this is the java.lang.StringConcatHelper#stringOf code

the null check just doesnt work lol

i can also not replicate this on my machine with the same data

[lilac dagger]

If value is equal with null returns true

Maybe write a print above the return to see whsy your value is

[placid moss]

you should make the code a bit longer, because some things may not work as expected when you shorten everything into one line

just seperate the if statements

[glossy venture]

this is jdk code

i didnt write this

this is from openjdk

but i can easily see that if the value was actually null as defined by the jvm it would work as intended

my value is some kind of special null it seems like because checking == null doesnt do shit

[glossy venture]

i also cant print it

trying that throws the error i showed above

[tall dragon]

a special null huh

[glossy venture]

since the jdk string concatenation code can not handle the value

but the jvm still thinks its null when you attempt to deref it

[glossy venture]

yeah lmao istg

i made a special null value

i fixed it though, im pretty sure i made it with Unsafe

it was trying to get the boolean field from the Boolean class which somehow resulted in a corrupted object value or smth

but now that i made a special case for it it works

[tall dragon]

i wonder why its deemed unsafe

[slender elbow]

it's easier and safer to just --add-opens and use reflection regularly lmao

[glossy venture]

yes but slow as fuck

unsafe is faster than bytecode

like i generated bytecode for the serializers which used GETFIELD and shit and it was slower than using Unsafe

and im not gonna require ppl to add flags ill just use Unsafe and method handles to remove encapsulation

java security is bullshit when its so easy to break it why even have it

its just annoying

[lilac dagger]

Well, there's a reason why security manager is deprecated

[glossy venture]

true

its been deprecated since like java 14 or smth tho

also will something replace it then or what

[lilac dagger]

No

It expects you to give proper permission from the os

[slender elbow]

before C2 hits, sure, but no-one's running with -Xint lmao

reflection is slow if you don't optimise for it

[glossy venture]

wdym if you dont optimise for it

[glossy venture]

also yeah a good JIT will prob make it faster, doesnt it have to do access checks though

[slender elbow]

not once it has asserted it's visible

[slender elbow]

the JVM aggressively inlines constants (static final fields), and that is especially true for core reflection and MethodHandle/VarHandle invocations

[glossy venture]

oh it prob does that when resolving the reference from the constant pool yeah

but why tf is it still so slow

[lilac dagger]

Imagine writing final static fields just for jvm to just inline it anyway

[glossy venture]

VarHandle might work yeah but i still think Unsafe should be faster

[slender elbow]

have you properly benchmarked it.., like, jmh

[slender elbow]

VarHandle is the literal API replacement for Unsafe lmao and it uses it under the hood

which is inlined

[glossy venture]

oh sick

[glossy venture]

nah im also exaggerating but i did warm up rounds and repeated it a couple times and it was consistently slightly slower than Unsafe

its some goofy benchmark system tho so the results might be off

slightly

also idk if i could do any optimizations in the bytecode

i dont think so

[slender elbow]

we're talking nanoseconds here, the point of bytecode is to be simple, not optimiseable, that is for the runtime to do

[glossy venture]

nvm now the asm version is faster

couldve been java version but i think my benchmark system mightve just done some weird shit

[quiet ice]

Unsafe is generally faster due to intrinsification

[glossy venture]

at least its faster than ObjectInputStream

[quiet ice]

ObjectInputStream isn't great...
That is like comparing Windows XP to Win 98

[glossy venture]

i know but i was using that before

so im happy it was at least slightly worth it

[quiet ice]

Do you at least have strong enough protection against malicious data?

[glossy venture]

idk

[quiet ice]

Half of Javas exploits come from ObjectInputStream

[glossy venture]

its for internal communication tho

closed network

so im not too worried about that

[glossy venture]

how did this happen tho

also here is the unoptimized write method the loop and switch is prob the reason why its slower https://pastes.dev/2busIxU3Ra

fuck i forgot to handle booleans again

[quiet ice]

Gotta love net connection speeds that are slower than modems

[fallen lily]

Refer to my private messages for a business enquiry 🙏

[quiet ice]

Also I am bewildered at your ability to write Java code that looks like C code

[glossy venture]

lmao

[fallen lily]

fr

My initial thoughts

[glossy venture]

do you think wt(stream, type).write(val) is faster because it returns the stream on top of the stack or { wt(stream, type); stream.write(val); } because the compiler can just DUP the stream on the stack and reuse it

or will the jvm do that

[slender elbow]

bro it literally does not matter

[glossy venture]

i need the nanoseconds

[slender elbow]

don't run in interpreter mode then

[glossy venture]

it doesnt

[slender elbow]

then don't worry

profile first, act after results

proper profiling is key

[scenic onyx]

?paste

[undone axle]

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

[scenic onyx]

https://paste.md-5.net/kuleqatela.cpp get error "Location loc1 = new Location(v1.getX(), v1.getY(), v1.getZ());" because the sintax is new Location(World, x, y,z ) how i can do?

[echo basalt]

pass null

[scenic onyx]

ok

[echo basalt]

actually just pass a world context

param

what you're writing is weirdly structured

[scenic onyx]

i do it now

how i can do entity.getEyeLocation().getDirection();???

[young knoll]

What

[scenic onyx]

how i can get vector of eye

[young knoll]

The position vector or the look vector?

[inland dust]

how can i do more commands in a single class file?

[scenic onyx]

look vector

[glad prawn]

getEyeLocation#toVector ?

[pseudo hazel]

wtf is the Distance class

[young knoll]

That is the look vector

Entity.getEyeLocation.getDirection

[scenic onyx]

dont exist

[glad prawn]

huh

[young knoll]

Might only be on LivingEntity

[scenic onyx]

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

[scenic onyx]

ok

[pseudo hazel]

right

looks kinda like a raycast

but anyways, I checked and it is on livingentity

[inland dust]

how can i async blocks?

[young knoll]

What

[sullen canyon]

? He just wants to async blocks

what didn't you understand

[young knoll]

-_-

Do you want to edit them async, read them async, turn them into a sink?

[remote swallow]

an asink

[inland dust]

how can i async like the wood block

[worldly ingot]

Okay how do we explain this? lol

You cannot just "async a block". That means nothing

[lilac dagger]

Getdirection instead of tovector

[young knoll]

I want logs to have their own thread

[lilac dagger]

That's doable

[young knoll]

Lol what would that even do

Logs don't tick or anything

[lilac dagger]

But isnt the file already written async

[worldly ingot]

Asynchronousy is taking a task and performing that on a thread separate from the server's main thread. The wood block doesn't do anything. There is no task to accomplish. So what do you want to do with this wood block? Do you want to change it to some other block? If so, asynchronous world writes are not supported and can leave the world in an irrepairable state

[inland dust]

i want to async because someon told me the runTaskLater take a lot of prestaction of the server

[worldly ingot]

Someone was probably talking out of their ass

It depends on what you're doing

[inland dust]

that is the code i done with runTaskLater

    public void onBlockPlace(BlockPlaceEvent event) {
        Player p = event.getPlayer();
        Block under = p.getLocation().clone().subtract(0.0D, 1.0D, 0.0D).getBlock();
        if (event.getBlock().getType() == Material.OBSIDIAN) {
            p.sendMessage("hai piazzato un blocco di obs!");

            new BukkitRunnable() {
                @Override
                public void run() {
                    event.getBlock().setType(Material.AIR);
                    p.sendMessage("Il blocco e' stato rimpiazzato in aria!");
                }
            }.runTaskLater(plugin, 200);
            if (under.getType() == Material.OBSIDIAN) {
                p.sendTitle("Sei sopra un blocco di obs", "OSSIDIANA!");
            }
        }
    }```

it's tthe change of a block after an amount of seconds

[worldly ingot]

Yeah, don't run that asynchronously. You're changing a block. It's not supported

[lilac dagger]

Just learn about time complexity and memory complexity and in 99 % of cases your problems resolve themselves

[worldly ingot]

You're changing a block type which will take you nanoseconds to do. Probably less than that 😛 You don't need it async

[lilac dagger]

From within the main thread

[young knoll]

You may want to make a single task that handles replacing blocks later instead of making a task for each

But I doubt it matters much

[inland dust]

then if like 10/20 players do that in the same time will do nothing right?

[lilac dagger]

Yeah, you can always spread the block placing over many ticks

It'll spread the load and you won't feel it

[worldly ingot]

You have to keep in mind that a significant majority of Minecraft is run single threaded

[young knoll]

You won't feel it anyway

It's 20 blocks being changed at once

[worldly ingot]

Every single entity, block entity, particle, sound, block logic, containers, literally anything and everything in Minecraft, is being processed synchronously

Your single block change will not affect it lol

[lilac dagger]

That's nothing then

[young knoll]

Spigot async everything when?

[inland dust]

oh ok thx a lot ❤️

[echo basalt]

ehh

[lilac dagger]

If it wouldn't be so difficult why not

[echo basalt]

particles not really

[worldly ingot]

anything and everything [...] is being processed synchronously
massive generalization

For all intents and purposes, this is true though

[echo basalt]

Well

[inland dust]

can i ask another question?

[worldly ingot]

FOR ALL INTENTS AND PURPOSES

THIS IS TRUE

lol

[echo basalt]

I guess the packet thread is only a single thread per player

a lie it is not

[lilac dagger]

Probably less

[worldly ingot]

We are not getting into packet level details here or the specificities of asynchronization of the server when he's just trying to set a block 😛

[lilac dagger]

I heard something about netty thread pool

It must spread the load across those threads

[inland dust]

how can i put 2 or more command in the same .java file but let they get executed from diffrent command like i want to lock the command /plugin / pl how can i do it within a single fie?

file*

[echo basalt]

alias?

[inland dust]

i want to do differnt actions too

[young knoll]

I think the main thing that would benefit from being async atm is entities

[echo basalt]

does it really need to be on a single file

What's the benefit other than just having a file with 5000 lines

[inland dust]

u are true XD

thx a lot ❤️

@worldly ingot the guy told me the think of RunTaskLater said :"Distributed workloads or an asynchronous task with a map of blocks and times"

[worldly ingot]

Yeah it doesn't need to be async. They're high

You can create a single task to replace a list of blocks at specific timestamps, which Coll also suggested (and is probably going to save you from creating tasks over and over again), but it definitely doesn't have to be async

And in fact probably shouldn't because you're modifying the state of the world

[remote swallow]

distributed workloads would only be needed for an insane amount of block changes

[young knoll]

No modifying the state of the world async

Meanwhile FAWE

FAWE really doesn't need to exist

[inland dust]

then it's a good think if i change from RunTaskLater to workloads right?

[lilac dagger]

Usually you shouldn't be doing large block manipulation on a production server

[worldly ingot]

You're A-okay using the task you're using now, Phonk. lol

[young knoll]

ooh shots fired

[inland dust]

what A-okay mean?

[worldly ingot]

In the clear. Good to go

Nothing needed to change

No, Choco is not real. I was not programmed to say this by Sam.

JIT compiles stack operands well. I'd say returning void is actually better

[hushed spindle]

putting an enchantment level of 0 results in level I right or was that just a potion effect amplifier thing

[young knoll]

just potion effects

[hushed spindle]

gotcha thanks

[shadow night]

does block break event trigger on any block break or only the player?

[echo basalt]

player

[shadow night]

hm

[young knoll]

I'm still thinkin about makin that block remove event

[shadow night]

ig then blockbreak and explosion should work

[shadow night]

good idea

[zenith gate]

So, I am working on character skills rn, and I don't know how to upgrade the skills based off their level. My current thought process was to use if statements check for level and do the stronger variation of the ability.

if (currentLevel >= 11) {
    .....
} else if (currentLevel >=22 ) {
    .....
}
......

But doing this makes everything else unreachable, and im just drawing a blank, don't know how to structure this.

[echo basalt]

Algorithms!

Let's say you have a "strength" skill that has levels from 1 - 100

And every 5 levels you want to give health to a player

You can just do something like
int healthToAdd = level / 5

[young knoll]

We love math

[echo basalt]

yep

[zenith gate]

Yeah, I understand that, the thing is, these skills can be used over and over and whenever, so the player could be a different level. there are certain sections in the levels where everyone has access to certain things. e.g beserk skill gives buffs, but it cost less mana and last longer the higher level you are. I don't know how to structure when to give what variation of the buff.

if (currentLevel >= 11) {
    .....
} else if (currentLevel >=22 ) {
    .....
}
......

This here only the first if statement runs nothing else will, because the first one will always be true. i dont know how to make this idea work in a sense.

[glad prawn]

i dont

[echo basalt]

So skill tiers?

More math!

Or if you want to be quirky you can use uhh

[zenith gate]

Yeah. i just dont know how to think of it.

[echo basalt]

data classes for this kind of stuff

[zenith gate]

lets stick to the norm lol

[echo basalt]

public abstract class ActiveSkillData {

  private final int skillLevelRequirement;
  private final int manaCost;
  
  protected ActiveSkillData(int levelRequirement, int manaCost) {
    this.skillLevelRequirement = levelRequirement;
    this.manaCost = ...;
  }

  public int getLevelRequirement() {
    return skillLevelRequirement;
  }

  public abstract SkillType getSkillType();

}

public enum SkillType {

  STRENGTH,
  ...
  ;
}

public class BerserkerActiveSkillData extends ActiveSkillData {

  private final float damageBoost;

  public BerserkerActiveSkillData(ConfigurationSection section) {
    super(section.getInt("level-requirement"), section.getInt("mana-cost"));

    this.damageBoost = (float) section.getDouble("damage-boost");
  }

  public SkillType getSkillType() {
    return SkillType.STRENGTH;
  }

  public float getDamageBoost() {
    return damageBoost;
  }
}

something like that

rest is up to you

that's just one way to do it

[zenith gate]

How would this fix the different level for skills thing? if someone is level 11 they can have the first varation but once they get to level 21 they get an upgraded, but it checks for the level everytime, and i want them to have the first varaition until they reach 21. then the 2nd unclocks and they can continue using the 2nd varation until level 27, where the 3rd unlocks. I don't really understand what that does.

[echo basalt]

you kinda need to loop on the opposite way

ActiveSkillData is a "variation"

You can do something like

loop through all the variations, from the highest level to the lowest

And if the player's level belongs to that variation, stick to it

[zenith gate]

Okay, that makes a little more sense.

[upper hazel]

who knows why annotations are needed? I mean, there is inheritance of interfaces, etc.

reflection is very resource intensive

only disadvantages

[hazy parrot]

you don't have to use reflection during actual runtime

its usually during aplication startup

as startup time usually doesn't matter

[upper hazel]

hm

[hazy parrot]

also reflection is pretty much faster in newer java versions

[upper hazel]

and for this reason people decided to give more importance to convenience than speed?

[fossil flax]

i want to replace a default minecraft command with a custom one that i created in my plugin, how can i do?

[hasty prawn]

Yeah I mean as with any other thing, if you're not just calling it tons of times for no reason, you probably wouldn't be able to notice any performance hit

[upper hazel]

hm

Well, if you look at it from this side, will registering commands be convenient and at the same time not resource-intensive in the process if you use annotations?

The lengths people are willing to go to avoid comparing arguments

[warm mica]

Spigot doesn't force you to use annotations, you may also i.a. register your listener method manually https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/HandlerList.html#register(org.bukkit.plugin.RegisteredListener)

However, I believe that the overhead you get from reflection is negligible and possibly not something that you'd actually notice in practice

[wicked quail]

Does anyone know a way to automatically get the getMappingsVersion() string during the plugin compilation and, for example, save it to a maven property or put it in a file (like what com.google.code.maven-replacer-plugin does)? This would be very helpful working with NMS since the checking of getMappingsVersion() would be automatable.

Also, doesn anyone know what that string means? Or if it even has a meaning or it's just random

[warm mica]

I'd guess that this is a version number that is given by Mojang

[inner mulch]

what do i need to type in my pom.xml that it save my plugins into the file i want them to be?

[worldly ingot]

It's a randomly generated hash. And no, I don't think there's a way to get that with a Maven plugin

[quaint mantle]

also reflection is pretty much faster in newer java versions

[full holly]

Why am I getting this error: java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_19_R3.block.data.CraftBlockData cannot be cast to class org.bukkit.material.PoweredRail (org.bukkit.craftbukkit.v1_19_R3.block.data.CraftBlockData and org.bukkit.material.PoweredRail are in unnamed module of loader java.net.URLClassLoader @759ebb3d) when casting this: PoweredRail rails = (PoweredRail) clone.getBlock().getState().getBlockData();

[spiral light]

material and data is not the same

try Block#getBlockData()

[full holly]

same error

[spiral light]

can you provide code ?

[full holly]

Location clone = ...; clone.getBlock().setType(Material.POWERED_RAIL); PoweredRail rails = (PoweredRail) clone.getBlock().getBlockData(); location.getBlock().setType(Material.POWERED_RAIL); PoweredRail secondRail = (PoweredRail) clone.getBlock().getBlockData(); secondRail.setDirection(rails.getDirection(), rails.isOnSlope()); location.getBlock().setBlockData((BlockData) secondRail);

[spiral light]

what version do you use ?

[remote swallow]

PoweredRail is deprecated

[worldly ingot]

You're deprecated

[chrome beacon]

Did you forget the new keyword: new Color(int, int, int)

[remote swallow]

bot shut up

[spiral light]

Rail is from org.bukkit.block.data

but i wonder how i would check if its a powered rail

Thank you! I think I'll just try implementing one myself then (I'll make a post on the forum when it's done).

[chrome beacon]

https://ci.md-5.net/job/BungeeCord/ws/chat/target/apidocs/net/md_5/bungee/api/ChatColor.html

You probably imported the bukkit ChatColor instead of the Bungeecord one

[remote swallow]

check the material

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/block/data/Powerable.html

[spiral light]

nah thats not what i wanted ... i was searching for #IsPowered()
but its packed into Powerable ^^

[full holly]

The JavaDocs page says Rails extends MaterialData, so PoweredRail rails = (PoweredRail) clone.getBlock().getState().getData();. Or am I wrong?

[spiral light]

wrong

there is no PoweredRail anymore

if you want to check if your Rail is powered or not (and its a Material.POWERED_RAIL as well) you need to check the
Powerable power = Block#getBlockData()

[full holly]

and how can I check the direction and apply it to another rail too?

[spiral light]

Rail rail = Block#getBlockData()

[full holly]

thanks!

[spiral light]

Rail has getShape() and also getShapes (valid shapes that can apply) and a enum for all Shapes

[full holly]

java.lang.ClassCastException: class org.bukkit.craftbukkit.v1_19_R3.block.data.CraftBlockData cannot be cast to class org.bukkit.block.data.Rail (org.bukkit.craftbukkit.v1_19_R3.block.data.CraftBlockData and org.bukkit.block.data.Rail are in unnamed module of loader java.net.URLClassLoader @759ebb3d)

It's not possible to cast a powered rail to a rail

why?

[spiral light]

you could try RedstoneRail as well

[echo basalt]

powered rails can't turn

redstone rails can't either

[spiral light]

buttttt the BlockData says it can O.o

[echo basalt]

p sure

it's just regular rails that can

[spiral light]

they still have a shape O.o

[echo basalt]

well

they're directional

huh

[spiral light]

they just have not all shapes available ^^ but still have a shape

[glossy venture]

holy shit finally

[worldly ingot]

That's a lot of nested method calls

idk why

the husk and spider does have the tag

[chrome beacon]

Why are you using scoreboard tags instead of pdc

[chilly hearth]

actually

dont ask me why 😦

[ocean hollow]

I understand that you have made datapacks before?))

[chilly hearth]

nah

actually

i was trying to do smth with screoboard tags

and i had used them all diff classes

now its gona take ages to replace with pdc yk

but it should work with tags its working untilll ravager

[valid burrow]

If i have a data that i want to save in a db but that data updates like every second for each player is it smart to just temp save it in a var and update the data once the player disconects? or update it like very 10 seconds?

[quaint mantle]

there seems to be a bug with blockdata Leaves

[remote swallow]

cache it and save every 15-60 min

[quaint mantle]

Oak and Birch Leaves in particular thinks that it is waterlogged

[valid burrow]

alright

[remote swallow]

and on leave

[quaint mantle]

mangrove works as usual though

[chilly hearth]

.................

Guys! Why can't I create an inventory named like this: §1§9§2§3§7Menu

[valid burrow]

cache in what? a simple file or just variables?

[chilly hearth]

bruh

[remote swallow]

map or ur favourite choice

[chilly hearth]

just use one color code

[valid burrow]

alright thx ebic

[remote swallow]

thats not the format for hex codes

[quaint mantle]

Not "bruh". I'm trying to make an identifier for inventory titles.

[remote swallow]

add §x to the start

[river oracle]

I was about to reccomend components but then I remembered you need NMS for that

[remote swallow]

pr it

[river oracle]

choco already did

[remote swallow]

do it better

[quaint mantle]

You don't understand what I'm trying to do. I want to create an invisible identifier. It can be created for itemstacks, but I don't know, why I can't do the same for inventories.

[river oracle]

we are waiting on bungeechat array remover being merged

[remote swallow]

because that isnt hex format

[river oracle]

don't do that

identifying inventories by names is beyond dumb

[remote swallow]

you cant add an invis hex component without the right format

[quaint mantle]

How to do that then?

[remote swallow]

instance of the view inventory

[river oracle]

infact recently setTitle was added xD really shows you, you really shouldn't be identifying inventories by the title

[river oracle]

instance of the inventory not the view

[remote swallow]

forgot

[river oracle]

every inventory event provides you with an Inventory oyu can use

[remote swallow]

i havent done invs in a while

do you have the 7smile7 thread I'm on my laptop so can't send

[remote swallow]

heres an example

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

heres the spigot forum

[river oracle]

^ this is how you really should be doing it. Obviously I wouldn't expect you to copy this 1 for 1, but its a good guide on what idea you should be using

[quaint mantle]

But I am creating a menu of multiple inventories. How can I add an identifier, so that the plugin knows, that those are a part of a specific menu?

[remote swallow]

instance of the inv

[river oracle]

pagination is fun. Read the thread epic posted its really easy to go about it

remember Inventories override hashCode so Hashmaps will be useful here

[remote swallow]

you can see how i handle my invs here, it uses the same principle of the spigot forum but no class just for buttons

[river oracle]

alternatively https://github.com/Y2Kwastaken/Suketto/tree/master/bukkit-core/src/main/java/sh/miles/suketto/bukkit/menu something like this also works it has the same fundamental idea

[remote swallow]

suketto on deez nutz

[river oracle]

helper on deez nuts?

[remote swallow]

shut up

its not funny translated

[river oracle]

    static SlotHolder<SukettoContainer> of(@NotNull final SukettoContainer container) {
        return new ContainerSlotHolder(container);
    }
``` :3 I love this method doens't it look great

I still haven't updated my lib to 1.20.2

[remote swallow]

too compilcated

[river oracle]

I should really script this

[remote swallow]

6/10

i wanna write an nms wrapper

that can function of mojmaps or obsfucated and uses reflections/method handles

[river oracle]

imho my container system is ever so slightly better than spigots though its still a pain I might try to attack it with a diff angle in the nera future

[remote swallow]

eg NMSWrapper.getClass("net.minecraft.server.world.entity.player.EntityPlayer").getVariable("connection")

idk if that package is write

[river oracle]

e.g. right now I'm opening the menu before changing anything when really that should be done after

[remote swallow]

get variable would probably need some form of name cache for across versions and a return type param

[river oracle]

🤔 you'd have to download the map file or sometihng

[restive jackal]

are PDCs accessible through the data command? curious if I could set custom PDC data without needing a plugin

[remote swallow]

yeah

[river oracle]

really this should be done at a compile time in a maven and gradle plugin

[remote swallow]

you can but its painful

[remote swallow]

could do that

[restive jackal]

I'm a fan of pain /s

[remote swallow]

idk what the legality of that is though

[quaint mantle]

Looks good, thanks for the help!

[river oracle]

its definitely the best approach

if you do it at runtime you'd need to load the mappings into memory or you're slowing your nms calls down by having to run them asynchronously (again this doesn't mean on another thread)

[remote swallow]

would mojank or spigot appreciate me putting mappings on central

[river oracle]

💀 nah bruh

mojang lawyers might, they might be boared

give them something interesting to do

[remote swallow]

"hey boss this guy put all the mappings on maven central, what do we do"

[river oracle]

"take it down"

[river oracle]

epic did you know that Player#openEnchating doesn't work if no location is provided

[remote swallow]

no

fix it

[river oracle]

I did :P

[remote swallow]

ill obsfucate the obsufcated mappings

get shit ion

[river oracle]

enchanting tables are so wack

[remote swallow]

its probably for the xp

[river oracle]

like the menu won't work unless the block is in the world but like you could totally just ignore that and create the menu anyways and it works fine

[remote swallow]

wait

no it doesnt drop xp

spawn a table above their head and give them that

[river oracle]

there is a check to see if its placed in the world, but you can legit just ignore it and force create the menu anyways

                        new EnchantmentMenu(i, playerinventory, ContainerLevelAccess.create(player.level(), pos))
                        , ServerAdapter.toMinecraftChat(super.getTitle())```

[remote swallow]

expand the height map at 0, 0 and spawn one there

[river oracle]

providing container access doesn't actually create any block in the world

[upper hazel]

@river oracle godgo dead bro

[river oracle]

?

[remote swallow]

what in the fuck does that mean

[river oracle]

also another fun fact its deprecated so prolly will be removed eventually but every block has a method called getMenuProvider than can be implemented

[remote swallow]

nerd

[river oracle]

that doesn't make any sense, it should just be implemented as needed not used accross every single block

Minecraft Stone Menu Confirmed 😱. I just right clicked stone! You won't believe what happens next

gotta dead bro

his bro is dead?

[young knoll]

Maybe they meant godot

is there any public image to particle converters

[young knoll]

godot is dead

[river oracle]

well that wouldn't make sense

[young knoll]

Hey it might be dead

Maybe they killed it just now

[river oracle]

😭 I feel like it might be bad for the server, so I don't think so

[restive jackal]

I godgo geddaway
I annaflah awayy
yea
yea
yea

[young knoll]

I mean image to particle is pretty easy

[thin iris]

bad, why?

[young knoll]

Could make an executable jar for it

rather than a server

[river oracle]

lol bro meant gojo in my pfp

That would be an interesting headline; Especially in their current situation.

[terse pumice]

How would I go about checking if an item frame itemstack is an invisible item frame? My current thought would just be to get nbt and check if {EntityTag:{Invisible:1b}} exists

Yeah it appears we don't have a meta type for that

[remote swallow]

@worldly ingot add it

[upper hazel]

I encountered a problem when I tried to create an annotation for registering a command. How get commandSize from args (not maxArgsSize)

[river oracle]

you add it :P

choco is a busy man

no

[river oracle]

lazy

[remote swallow]

yup

[terse pumice]

I haven't really messed with nbt too much previously, what would be the best way to check that?

[worldly ingot]

iirc it's covered. Just can't remember what by

[terse pumice]

ooh ok

[young knoll]

Oh boy weird name time

[worldly ingot]

Trying to remember and find it

[river oracle]

is that not covered by BlockStateMeta?

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[worldly ingot]

I think it is, yeah

[young knoll]

It's not a block state

[river oracle]

oh its an entity 💀 worse

[worldly ingot]

It's covered by CraftMetaEntityTag but I don't know what the interface is for it

[young knoll]

inb4 there is none

[left pine]

Hello, I wanted to know if there is an event to save if the player right clicks with an item in the main hand?

[worldly ingot]

There might not be, actually

[young knoll]

kek

I don't see anything that stands out in the javadocs

[river oracle]

PlayerInteractEvent

[worldly ingot]

Honestly Coll, perfect candidate for your virtual entities

Implementation is already there and done

[terse pumice]

I couldn't spot anything either

What's a virtual entity?

[river oracle]

entities the player can see but they dont actually exist on the server

[terse pumice]

ohh

makes sense

[river oracle]

so the player sends the packet to the player saying its there but it really isn't

iirc ^

[young knoll]

No you can't see them

They exist on the server, but not as part of a world

[river oracle]

ahhhh okay

wrong way around :P

[terse pumice]

interesttingg

[young knoll]

Hmm so it's the exact same as spawn eggs

But without the entity type

Question is should it be split up into multiple metas for differnt entity types

[river oracle]

💀 nah bro sounds like a horrible idea we would have like 10 billion meta types

[terse pumice]

there wouldn't be too many right? unless i am misunderstanding

you'd have like item frame and leash(?)

[young knoll]

Item frame and armor stand have this tag

Haven't seen anything else yet

[terse pumice]

that makes sense

[young knoll]

Lead does not have it, neither does boat

[terse pumice]

thought maybe leash knot might

makes sense

invisible boat would be pretty cool lol

[young knoll]

I'm talking about items that make use of this tag

[river oracle]

Unless there are some other special attributes idk I don't see a reason too

[young knoll]

Well armor stand has differnt methods than itemframe

Sure the dev could cast but ehhh

[river oracle]

wouldn't it be best off to have 1 parent type then children type with the other items if needed

[young knoll]

Probably

[river oracle]

e.g. ItemEntityMeta or whatever
then ItemFrameEntityMeta and ArmorStandEntityMeta etc etc or whatever it'd be called

[young knoll]

Probably

Technically spawn egg meta could extend it too

Spawn eggs are special though because you can use entity type with them

[river oracle]

I've always wanted to integrate a better inventory system into bucket but its so messy 😭 and virtual containers are well, awful

[young knoll]

Which means yes, you can have a creeper spawn egg spawn a chicken

[umbral marsh]

anyone know how to detect if a falling block hits an entity?

[river oracle]

seems like a reminant of the good old days when that data mattered :P

[young knoll]

Give it damage and then it should trigger an event

[umbral marsh]

How would I do that

[young knoll]

FallingBlock#setHurtEntities

[umbral marsh]

hmmm

[young knoll]

there's also setMaxDamage

[umbral marsh]

Let me try that

I only want it do damage to the player

[young knoll]

Yeah then set it to hurt entities, set the damage, and then listen for the damage event and cancel it if it's not a player

[worldly ingot]

Fish buckets (cod, pufferfish, salmon), item frames, glow item frames, and paintings

I'd imagine boats and armour stands are included as well but were just never updated

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/inventory/CraftMetaEntityTag.java#15-22

[young knoll]

boats don't have it

According to the wiki

[river oracle]

you;'re on the new wiki right :P

[young knoll]

mhm

[river oracle]

beast

[young knoll]

They also don't show the option on mcstacker

Hmm painting also don't show it on the wiki

Seems to be

[glad prawn]

https://minecraft.wiki/w/Painting wat

[umbral marsh]

letting you know that doesn’t work for falling blocks

I’m compiling rn for the other thing tho

[young knoll]

cod, salmon, pufferfish, tropical fish and axolotl buckets (not tadpole for some reason), armor stands, and both item frames

Will require some testing I guess

So should there be subclasses for the specific entity types?

[worldly ingot]

Want to know the great part about tropical fish needing support? There are overlapping ItemMeta types again 🙃

I had to deal with that bullshit for the first time when adding ArmorMeta

[young knoll]

For some reason tropical fish has 2 tags

wtf mojang

[opaque scarab]

Is the a way to have pistons move unmovable blocks?

[young knoll]

Uhh

Technically yes

[opaque scarab]

I’m sure there is with the API, but I have no idea how

[umbral marsh]

Awww it doesn’t work

Can I send code?

[young knoll]

I did it with ASM

kek

[opaque scarab]

What is ASM?

[young knoll]

ASM is an all purpose Java bytecode manipulation and analysis framework. It can be used to modify existing classes or to dynamically generate classes, directly in binary form.

[opaque scarab]

Oh lovely LOL. I’ll need to modify the class of a block?

[quiet ice]

Whomst dared to mention ASM?

[terse pumice]

Coll is what you're working on a pr for spigot or a separate lib?

[quiet ice]

You've summoned the geolykt

[young knoll]

https://github.com/Jishuna/BetterPistons

[opal juniper]

what does it do

[quiet ice]

Oh apparently nothing of note. I sleep.

[young knoll]

Oof

My feels

[opal juniper]

night night geol

[young knoll]

Lets pistons push any block

[umbral marsh]

hey coll

                Location loc = player.getLocation();
                FallingBlock block = player.getWorld().spawnFallingBlock(loc, Material.GRASS, (byte) 0);
                block.setHurtEntities(true);
                block.setVelocity(player.getLocation().getDirection().multiply(2.0D));
            }```

[opal juniper]

illegal

[quiet ice]

Why would you even need ASM there?

[young knoll]

How else you gonna do it

[quiet ice]

Oh, you are retransforming classes. That is cursed.

[young knoll]

hehehe

[opal juniper]

doesn’t that break like a lot of stuff

[scenic onyx]

how i can get the block lokking of player?

[young knoll]

Might break other plugins that mess with those specific NMS classes

[opal juniper]

ray trace

[remote swallow]

player.getBlockExact

[opal juniper]

nope i mean like piston machines and stuff

i thought that it would mess with that

[young knoll]

nop

Well, if they rely on something not being movable then yes

[quiet ice]

You are aware of https://bugs.openjdk.org/browse/JDK-8306275, right? So does it break on J21 or not?

[young knoll]

It has a config for that

No idea

"Issue warnings when agents are loaded dynamically into a running JVM."

Probably not yet

[umbral marsh]

here is my code

[scenic onyx]

.

[quiet ice]

Ah you are using bytebuddy, in that case it would still work as long as you keep it updated.

But smh, not using raw ASM.

[young knoll]

It is raw asm

Bytebuddy is only for injecting into class loader

[quiet ice]

Albeit that would be equally cursed

[young knoll]

and injecting the transformers

The transformation itself is raw ASM

[quiet ice]

Yeah I know

[young knoll]

Well

Blah to you

[quiet ice]

I find it interesting that most people add a wrapper around the ClassVisitor/ClassNode schema. What is the point in that?

[opaque scarab]

There’s no other way to move a piston LOL?

[umbral marsh]

                Location loc = player.getLocation();
                FallingBlock block = player.getWorld().spawnFallingBlock(loc, Material.GRASS, (byte) 0);
                block.setHurtEntities(true);
                block.setVelocity(player.getLocation().getDirection().multiply(2.0D));
            }```

[quiet ice]

Not in a way that would be good for performance

[umbral marsh]

the falling block still dont hurt entitys

[quiet ice]

So?

[opaque scarab]

Fantastic

[quiet ice]

I wouldn't use setHurtEntities generally

[umbral marsh]

what would you use?

[quiet ice]

Manual proximity checks and more explicit damage handling (in order to not cause overly generic events)

[frosty geyser]

is there a simple way to see if a server version is greater than 1.16? (without NMS)

[quiet ice]

However uh, that is the code that I've been inherited and it is very old code as it stems from pre-1.12 times

[quiet ice]

If you know some class that was added in 1.16 - just fetch that class via reflection and check wether that works

[umbral marsh]

ummm... how would I do that...

as you can tell by my leaf, i am new as heck to this stuff

[quaint mantle]

Anyone know a gradle plugin to code smth using mappings and then deobuscate smth once it’s compiled

[frosty geyser]

yea I don't know any classes that are 1.16 and above specific, was just trying to implement hex colour code support if they used 1.16+

[quiet ice]

The most obvious choice would be to go with a newly added material but that wouldn't actually be great.

[remote swallow]

for nms?

[tribal quarry]

(Adventure)
Hello, does replaceText invocation affects hoverEvents & other stuff, or its just text?:

message.replaceText(b -> b
    .matchLiteral(entry.getKey())
    .replacement(entry.getValue()));

[quaint mantle]

No, the thing I’m working on requires me to obfuscate the jar but I am tryna code without the obfuscated jar

[remote swallow]

do you hav emappings

[quaint mantle]

i would be using proguard mappings

[tribal quarry]

paperweight

[remote swallow]

paper weight is for nms

read what hejust said

[quiet ice]

I'd assume it is the former

[umbral marsh]

hey geol how would i do those proximity checks? and damage handling?

[remote swallow]

uh i cant seem to find anything

it probably exists just i cant findit

[quaint mantle]

Should I just skid paperweight and make my own

[tribal quarry]

sorry

[young knoll]

Dear god CraftMetaSpawnEgg is an abomination

[quiet ice]

I personally do https://github.com/Geolykt/EnchantmentsPlus/blob/4xx/src/main/java/de/geolykt/enchantments_plus/enchantments/Anthropomorphism.java#L120-L145 but as I said that is ancient code

[remote swallow]

if you dont have a deadline yeah you probably would want to make ur own

[quaint mantle]

I don’t have a deadline, also any idea if u can publish private gradle plugins to jfrog

I’ve never made a gradle plugin before

[remote swallow]

isnt jfrog dead and you can publish it anywhere aslong as you give gradle the repo

[quaint mantle]

Wdym dead

[remote swallow]

something j died like last year

cant remember if it was jfrog or something else

[quaint mantle]

Idk my team still uses it

[quiet ice]

No. Unless you are absolutely sure that you want to enter the realm of gradle. It is rumoured that everyone that hasn't turned back was never seen again

[remote swallow]

jcenter

thats it

[quaint mantle]

Must be smth else

[quiet ice]

jfrog shouldn't be used regardless

[quaint mantle]

What? I’d much rather use gradle then proguard

[quaint mantle]

Why

[remote swallow]

it should work with artifactory

[quiet ice]

You'd generally want to roll your own repository for private stuff

[quiet ice]

Gradle is .... let's say it is unique.

[quaint mantle]

It is, it’s a private artifacory is it not

[quiet ice]

Especially gradle plugins tend to be a bit strange in layout that chances are jfrog may block your upload. You are better off going to the gradle plugin center if a private repo isn't viable

[quaint mantle]

Uh we publish the ver to jfrog every time we compile so idk

With a new ver patch obv

[quiet ice]

If you know that you can publish gradle plugins to jfrog then great. Otherwise I cannot guarantee anything

[sterile token]

Is there a way to convert custom "&" for color into ChatColor.Enum?

Because there is bug when you use bungee components and colors via the char. It happens that apply the color to some lines of the whole component

[worldly ingot]

Yeah because you shouldn't be mixing legacy text with components

[sterile token]

perfect, what about this?

public static BaseComponent[] createCustomComponent(String input) {
        Pattern pattern = Pattern.compile("&[0-9a-fk-or]");
        Matcher matcher = pattern.matcher(input);
        List<BaseComponent> components = new ArrayList<>();
        int previousEnd = 0;

        while (matcher.find()) {
            int start = matcher.start();
            int end = matcher.end();

            if (start > previousEnd) {
                String plainText = input.substring(previousEnd, start);
                components.add(new TextComponent(plainText));
            }

            ChatColor color = ChatColor.getByChar(matcher.group().charAt(1));
            if (color != null) {
                TextComponent textComponent = new TextComponent(input.substring(start, end));
                textComponent.setColor(color);
                components.add(textComponent);
            }

            previousEnd = end;
        }

        if (previousEnd < input.length()) {
            String remainingText = input.substring(previousEnd);
            components.add(new TextComponent(remainingText));
        }

        return components.toArray(new BaseComponent[0]);
    }

[lilac dagger]

You can use a method to turn legacy text into a component

And then append it to your components

[sterile token]

isnt that?

[lilac dagger]

It's better that what you're doing

[sterile token]

how? But that will broke, because you mixin componentes with legacy text, what said the staff not doing

[lilac dagger]

Not sure how it was called

It won't, it'll make the hierarchy like you're supposed to

From the legacy text

[sterile token]

What i thought was, the only way color works great is via TextComponent#color() so i said, well i can just create a parser from &<color> obtaining its ChatColor object, to finally apply to the component

What you think choco? I see you typing too much and im really anxious haha

[lilac dagger]

You can do this too

But if it's done for you in the api, why bother?

[worldly ingot]

Just as a general note, please avoid arrays for components. It can be represented as a single component.

public static BaseComponent createCustomComponent(String input) {
        Pattern pattern = Pattern.compile("&[0-9a-fk-or]");
        Matcher matcher = pattern.matcher(input);
        ComponentBuilder builder = new ComponentBuilder();
        int previousEnd = 0;

        while (matcher.find()) {
            int start = matcher.start();
            int end = matcher.end();

            if (start > previousEnd) {
                String plainText = input.substring(previousEnd, start);
                builder.append(plainText);
            }

            ChatColor color = ChatColor.getByChar(matcher.group().charAt(1));
            if (color != null) {
                builder.append(input.substring(start, end)).color(color);
            }

            previousEnd = end;
        }

        if (previousEnd < input.length()) {
            String remainingText = input.substring(previousEnd);
            builder.append(remainingText);
        }

        return component.build(); // You can use #create() if you REALLY need a BaseComponent[]
    }```

Really not much reason to not use a ComponentBuilder here

[sterile token]

oh right really thanks, thanks sir

Can i see what yo umean @lilac dagger ?

[remote swallow]

hi chocus

[worldly ingot]

I don't know if your logic is sound by the way. I just converted it to use a ComponentBuilder lol

[lilac dagger]

I don't have my pc on hand to look 😦

[sterile token]

yeah i havent try it, i will have to try it hehe. I dont think it would be fixed to componen ts but idk

[sterile token]

oh rgiht, no problem man. Just tag me if you found it or remover it. Thanks you too

[lilac dagger]

But i am 100% sure there is a from legacy to component somewhere in there

Just search the md components for it

[sterile token]

There is a Component#fromLegacyText() is what you mean?

[lilac dagger]

Try that

Yes

[sterile token]

But that brokes too if im not wrong

[lilac dagger]

It shouldn't i think

[sterile token]

Thats what causing color being apply to some lines and the others get without the color

[lilac dagger]

It actuslly parses the legacy text

And i'm pretty sure it supports bold and underline

[lilac dagger]

Weird

It shouldn't cause issues

[worldly ingot]

I mean yeah if you're insistent on using legacy colour codes that's the method you should be using

But if you're using components you should ditch the notion of legacy format codes entirely

[eternal night]

components

[sterile token]

yeah the problem comes when using config files, you wont be creating components for them

And also you have to make huge configurations for configuring component messages

[worldly ingot]

If you want to use BungeeChat still there's MineDown as a library you can use for parsing, or if you want to use Adventure then there's MiniMessage

[young knoll]

Minimessage

We still need ChocoMessage

[sterile token]

yeah but thats a huge library, has thousens of classes

[river oracle]

ChocoMessage when??

[river oracle]

what do you need components for

from configuration messages? just use MineDown its relatively small, provides nice BaseComponent[] (and I add an extra step and reduce the array into a BaseComponent)

[sterile token]

Being able to apply legacy color coudes, without getting them bug

[lilac dagger]

Yeah, legacy text is still pretty cool

[worldly ingot]

Like I said, MineDown is a good option

https://github.com/Phoenix616/MineDown

[river oracle]

MineDown is perfect for this. If you don't want the array too you can always reduce it into a single component

[worldly ingot]

It's only 5 classes

[sterile token]

yeah only for that. Because if i dont want them to configure just use Component with color already set up, but what if you want to configurable? So there you have to do many and huge configurations

[river oracle]

I shade minedown into all my projects

its great

[sterile token]

Right really thanks to all i will try it

[lilac dagger]

Minedown does sound pretty cool

But i think bungeechat would be cool if it had some way to parse legacy chat for clickable/hoverable

[sterile token]

Yeah my goal is to make a fully and simple library working for both platform 😂

[worldly ingot]

I'm going to figure something out. Whether it's getting MineDown directly integrated into BungeeChat or adopting MiniMessage's language syntax

I want something easy

[lilac dagger]

I feel like choco would say, "you can always contribute"

[worldly ingot]

Paper will inevitably remove BungeeChat. They despise it

It's been deprecated for a long while now, it will go

[sterile token]

Choco if i design a simple and functional components system for spigot would be apply as contribution? How about the probability

[worldly ingot]

We have a component API

I'm finalizing it 😛

[sterile token]

oh you doing one better really nice

[lilac dagger]

I'm not gonna support another component system

[river oracle]

finally I won't have to manually turn BaseComponent[] into BaseComponent 🙏

[lilac dagger]

Imagine if java kept breaking stuff

Not fun

[sterile token]

totally agree}

[worldly ingot]

Yeah I made sure to drop array syntax because it was never really necessary, just conflated with existing API is all

[sterile token]

yeah java, is a broken fucking lang. Just changing 1 line can broke something

[river oracle]

are bungee components mutable or immutable

I've never looked

[worldly ingot]

They're mutable

I need to maybe figure something out for that too? Not sure

[sterile token]

what means mutable?

[worldly ingot]

https://paste.md-5.net/umifufequd.diff full API patch I have ready by the way

[river oracle]

I feel like they should not be mutable

[sterile token]

I dont understand the sense of mutability with texts?

[drifting viper]

Hello, I created a Post thats intention is to Provide Learning Resources to Beggining with Developing a Minecraft Java/Bedrock Anti-Cheat
https://gist.github.com/Snowiiii/2c306f3e8926bc7fb8acaaa8c3c105d7

[quiet ice]

So?

[sterile token]

Such a really nice note, would love to keep it pin

[drifting viper]

thanks ❤️

[sterile token]

I like the introduction where you explain really well about the packets, thats really interesting topic to make about it

I would love to find such a great information fully related to working witth Packets, because we most of here dont really have the best or been friends of packets to use them correctly

[drifting viper]

Ye, I saw there where really not much resources about Macking an Anti-Cheat or something like that most of the knowledge just comes over time

[chrome beacon]

That's an advanced topic

[sterile token]

Yeah, only 10% of developers known about making them correctly. What do you think ppl in general?

[chrome beacon]

Don't expect any tutorials

[sterile token]

Let discuss about the topic

[chrome beacon]

You'll learn over time how the game works internally and then you can work from there

[ivory sleet]

no not even 10%

more like 1% if even that

[sterile token]

Yeah i think understanding the base is the most important thing, but im really stucked around how mojang process the packets with Netty

Because they just use them raw, they dont even use Protobuf so you deal a lot understand fucking data types

[drifting viper]

ye NMS is really ugly, But many Packet Librarys makes your Life alot eaiser

[sterile token]

Yeah, but doest make sense just using a library and thats done

Because if you know how packets works internally, you know to came with solutions

[quaint mantle]

well issue with packet libs is that things become slower

[sterile token]

i just use weird conventions that ppl here uses hahaha

[drifting viper]

I guess its true that like only 1% of Developers are really Heavily into Packets, especially into Anti-Cheats, Thats the Reason there are not many Realy Good Anti-Cheat, I Mean at this Point the Most is just scam Intave, Matrix, Artermis and more costs hundreds of Dollars but are not that Good

[quaint mantle]

lmao

yeah they are a fkn scam

[drifting viper]

The Reason is that there is not an Big competition

[lilac dagger]

I could make a better anti cheat

[quaint mantle]

doubt

[lilac dagger]

In fact i'll just make something for aimbot and post it

[quaint mantle]

even if u are competent it demands a lot of time

[quiet ice]

There is a lot more competitions than with other kinds of plugins

[sterile token]

A really nice example of shity and scam anticheats is called Verus, cost over 120 usd they license for using and doesnt even give exact positives about the "lagging cheat"

[quiet ice]

Multi-currency economy implementations are few are far spread out for example.

[drifting viper]

yes this thing exists too, At this point i would not called it a Anti-Cheat anymore

[quaint mantle]

yes

[drifting viper]

Do you know Spartan Anti-Cheat ?

[quaint mantle]

for u to understand and be able to write anti cheats properly u need to be proficient in nms packet protocol, nms physics, netty and what not

[quaint mantle]

idk

[worldly ingot]

jfc remind me to finish my Economy service API

[quaint mantle]

i just know a lot of mediocre servers use essentials as an impl against vault

[sterile token]

In my case what doesnt help me is the shity and shity Mojang data types, why fuck they dont use plain Buffers without adding shity encoding

[quiet ice]

If you want to commit that to spigot you are a madlad

[worldly ingot]

I do! 🙂

[quiet ice]

Vault by itself is a monolithic currency API.

[quaint mantle]

bro

[sterile token]

madlad? is that russian?

[lilac dagger]

It better support async

[quaint mantle]

api without impl

[quiet ice]

No, it's florida man

[quaint mantle]

and quite poor

[quiet ice]

Yeah, but as the API does not support multi-currency the impls generally don't either

[quaint mantle]

mojang has done a nice job to map out primitive datatypes to more data oriented ones

[sterile token]

💀
And you can even bypass it

[quaint mantle]

idk, i wouldnt dare to touch vault

[drifting viper]

I was writing with the Developer of Spartan and asked him why the Anti-Cheat is Bukkit Events based and if he planning a Packet Rewrite, He told that he never had Problems using Bukkit Events and That if he would make a New Anti-Cheat he would use Packets but at the current State he would must be Rewrite everthing. So hes basicly to Laziy to Rewrite the Premium Plugin which many People use, I don't understand how this Anti-Cheat is so Popular

[quiet ice]

Great!

[quaint mantle]

it looks like a java 6 api

[quiet ice]

So what is the issue?

[quaint mantle]

its not well written

iirc it uses doubles

[quiet ice]

I have a project that is actually compiled with Java 6 - eventually I want to move to Java 5.

[quaint mantle]

and already there I decided to not touch it

the api developer who founded it must have been quite inexperienced when he started it

idk maybe its better now

[quiet ice]

Oh my god - you are one of the people to think that JIT optimizes short-lived objects.

[sterile token]

how much you think hypyxel anti cheat costs? any idea here i really interested on its price idk why

[quaint mantle]

no not rly

but doubles arent great precision wise

[quaint mantle]

oh its expensive

[sterile token]

Java is not precise for working with numbers

[quiet ice]

Only for very high values (read: Multiple billions)

[quaint mantle]

depends but yea
