    @EventHandler
    public void onRedstoneChange(BlockRedstoneEvent event) {
        Block block = event.getBlock();
        Bukkit.getLogger().info("powered 1");
        if (block.isBlockIndirectlyPowered() || block.isBlockPowered()) {
            Bukkit.getLogger().info("powered 2");
        }
    }```
why does this event get called like 5-20 times when i just power a block on/off once

[chrome beacon]

I'd assume it's triggered for every redstone update

[dry forum]

i only have 1 redstone circuit on my server though and its where im testing

[chrome beacon]

yeah so the thing with redstone is that it does a LOT of updates

[dry forum]

oh so when i turn it on/off its doing some random updates that arnt "visible"?

[chrome beacon]

yeah

[dry forum]

ohhh ok thanks

is there a better way to detect power on/off then?

[chrome beacon]

I know there's a good video that visualizes it

but I'm having a hard time finding it rn

[chrome beacon]

Not really

but there might be something that can be done depending on what block you're looking for or something else specific

[dry forum]

its a sign, ill keep trying stuff ty though

[thorn isle]

look at whatever craftbook does

craftbook did powerable signs before most current plugin devs were out of their diapers

[chrome beacon]

true

https://tenor.com/view/aging-getting-old-gif-9803364

Yeah they just use the BlockRedstoneEvent https://github.com/EngineHub/CraftBook/blob/master/src/main/java/com/sk89q/craftbook/bukkit/MechanicListenerAdapter.java#L184

You basically have two ways to go about it; BuildTools or Paperclip

If you're forking Spigot you can probably just fork BuildTools and make it build yours

[round finch]

whats the legal way of making modification like spigot?

[chrome beacon]

Don't distribute Mojangs code

(Not legal advice. Ask a lawyer*)

[wet breach]

technically decompiled code is not source code at least in the US

Everyone in the industry has not allowed that issue to go before the supreme court because odds are the supreme court will not rule in their favor in that decompiled code is the same as source code when it is not lol

Therefore, copyrights do not apply to decompiled code 🙂

[chrome beacon]

It'll be real expensive to defend yourself

[wet breach]

no

the person who brings forth a lawsuit is the one that has the burden of the majority of the cost

second, if you can't afford a lawyer the court will just appoint one for you as they are required to especially if you are not able to adequitely defend yourself

[lilac dagger]

isn't it a derivation anyway?

might not be source code but it's still their property

rockstar goes after those who make cheats

i also see this

[wet breach]

No. As I said not a single entity has allowed this to go before the supreme or circuit courts.

However if you want to treat it as such you can, which is perfectly fine. Just as long as you don't use everything you are generally fine

[wet breach]

cheats are not the same thing as going after someone who decompiled code. Cheats typically fall in the category of bypassing DRM

or can also be classified as illegal as you are accessing the system in an illegal way

Reverse engineering is legal in the US

No one can 100% argue that decompiled code is a derivative work simply because you are using software to interpret software

you also can't argue that method names being the same is enough either. Also, you can't copyright API methods from Java either(mainly because there is limited or a single way you can really write something to access a particular api as well as you can't copyright someone elses work just because you rely on it) and can only copyright code that you solely created. So you have to use code that is in the methods which may not be exactly the same in the decompiled or at all.

this is why all cases that involved decompiled code solely has stopped short from going any higher because the odds that it is ruled that decompiled code is not covered under copyright is really possible

so because of this, many of those for legal purposes just say yeah its covered under copyright to protect themselves, but reality is its just a big grey area because copyright doesn't address this and there is no official rulings on it from any high courts. IE no one really knows. I am on the side that, well its not specifically addressed therefore its legal simply because there is more precedent for things not being specifically addressed as being legal or not covered by a law.

closest we got to a case is AI generated stuff. Anything generated by AI can not be copyrighted

simply because AI can not be an author nor own anything

supreme court in the US ruled on that last year

As for other countries, I can not say though as I don't particularly care for laws in other countries

[lilac dagger]

i see

[chrome star]

ai can create somethings, the government won't mind

You can try

[wet breach]

not sure what you mean with this

[chrome star]

xD

[chrome star]

It's not the Ai that creates something, but the person who uses it

It is a tool for development assistance

[wet breach]

supreme court in the US ruled that anything created by AI can not be copyrighted

[chrome star]

ai this a not real developer

This is the assistant

!

[chrome star]

How will they prove it?

What was created by AI

?

The answer is: they won't prove it

[wet breach]

Not sure what you mean

but ok

knowingly filing a copyright that is fraudulent is a much worse offense then violating a copyright

and when you sue on copyright basis, you have to prove your copyright is valid

not that someone violated it

[chrome star]

I am using a Russian-English translator to speak with you

You may not understand me.

[wet breach]

I see so not even someone in the US

[chrome star]

I'm trying to get across to you that the court will be shown the source code without any markings or other things, and they won't be digging into whether it's Ai or not.

[wet breach]

This is not how it works in the US

[chrome star]

It's stupid to bring up this topic at all.

[chrome star]

How?

[wet breach]

when you sue someone, the burden of proof lies on you. Also, the defense can subpoena any evidence in your possession to include materials on computers and development environment as well as subpoena your employees or anyone else that may be witness

you are required to hand over any evidence already that may help the defense as well. You can't exclude evidence because it hurts your case lol

[chrome star]

You don't see a difference between the law and how it actually works.

[wet breach]

Except you don't know how it actually works since you are not from here.

[chrome star]

Can you find me any cases like this?

[wet breach]

Supreme court case in 2025

[chrome star]

send a link

[worldly ingot]

I mean let's be honest, even if he sent it, you would have read only the headline lol

But it wasn't the SCOTUS, it was the Supreme Court of D.C. whose ruling was challenged in the SCOTUS but has yet to be heard

Thaler v. Perlmutter, case No. 1:22-cv-01564

Unsure where the disagreement lays, but you're both correct. You can create something with AI and the government won't care, but you cannot copyright that work in the United States according to the Supreme Court of D.C. ruling against it

[random grove]

Does Spigot/craftbukkit include sqlite?

[slender elbow]

yes

[livid thorn]

Does ItemFlag#HIDE_POTION_EFFECTS still work to hide "Interact with Spawn egg:" on spawners?

[slender elbow]

idk about that, but ItemFlag.HIDE_BLOCK_ENTITY_DATA should do it

[livid thorn]

Still there

[chrome beacon]

Try HIDE_ADDITIONAL_TOOLTIP

[livid thorn]

That will hide whole lore right?

[chrome beacon]

No

[slender elbow]

if hide_block_entity_data doesn't do it, that's a spigot bug

[livid thorn]

It does not even do anything lol something weird is happing

[slender elbow]

sounds like you are misusing the itemstack/itemmeta or something idk

can't really tell without seeing any code

[livid thorn]

public ItemStack createSpawnerItem(String type, int amount, int level, int stack) {
        ItemStack item = new ItemStack(Material.SPAWNER, Math.max(1, amount));

        ItemMeta meta = item.getItemMeta();
        if (meta == null) return item;

        meta.setDisplayName("Test Spawner");
        meta.setLore(List.of("Line 1", "Line 2"));

        meta.addItemFlags(ItemFlag.HIDE_ADDITIONAL_TOOLTIP);

        item.setItemMeta(meta);
        return item;
    }```

created it just for testing

[livid thorn]

HIDE_BLOCK_ENTITY_DATA does not exist for me

[torpid blaze]

Hey,
I am currently developing a Minecraft Minigame Plugin of which I want to combine the base classes into a API Plugin to use in all my minigames. So I started creating generic classes. But now I have a problem with circular dependencies as I pass the used types through.
Now I am only confused anymore and don't know how to fix it without loosing type safety...
https://github.com/KesSaft/EnderGames
The problem is in the GameStateManager and other connected classes.

[ivory sleet]

What exactly is the point of the generic types params in this case?

[vagrant stratus]

Sounds more like a ground up rewrite is needed to properly take into account having an API

[ivory sleet]

well abstract class BaseGameData<E extends Enum<E>, P extends BasePlayerData<T>, T extends BaseGameStateManager<E, BaseGameData<E, P, T>>>, not saying this isn't needed, but this is a lot of generic type params

do u really need this kind of type awareness to shine through and propagate the rest of the code base

[vagrant stratus]

they probably don't lmfao

[ivory sleet]

😅

[lilac dagger]

i have very little generic stuff in my game engine

i just take advantage of polymorphism

[ivory sleet]

yea that can I understand

[vagrant stratus]

Something like this would be better lmfao

public abstract class BasePlayerData {
}

public abstract class BaseGameData {
  private BasePlayerData data;

  public BaseGameData(BasePlayerData data) { this.data = data;}

  public BasePlayerData getPlayerData();
}

[vital umbra]

Hey, um. I got a problem with my unity game could you help me please?
-# jk, don't kill me

[vagrant stratus]

Unironically probably to an extent

$$$$$$$$$$

I gave up on unity due to their dumb decisions though lol

[torpid blaze]

I want to put these base classes into a api plugin which I can use in all my plugins and so that the base class returns the right type, I want to pass it. else I would have to cast it everywhere right?

[vagrant stratus]

That is cleaner than.... whatever the fuck you're doing

[torpid blaze]

yea, it is like a infinite loop. But I am not sure how to do it properly.

[ivory sleet]

idk if u actually need like

[vagrant stratus]

If you're programming the implementation plugins correctly, you'll only have to cast once anyways

[ivory sleet]

type params at all in ur case

[torpid blaze]

yea, then I would need to cast it everywhere as most of the stuff I need will be in the extended class

[lilac dagger]

you can technically have a simple cast at getGameManager(Class class)

and from there you can access game specific methods

[vagrant stratus]

Nope!

[ivory sleet]

could u not just make an abstraction where u don't need to do so many casts

[vagrant stratus]

Only the implementation plugin has to cast, and if you program correctly you're only casting once lol

[torpid blaze]

😄 ok

[lilac dagger]

SpleggManager manager = registry.getByClass(SpleggManager.class);

[ivory sleet]

you can probably scope ur types kess-apps

[vagrant stratus]

e.g. This is how casting in Java works. Note the first line

TriggerZones plugin = (TriggerZones) pluginManager.getPlugin("TriggerZones");
RegionManager regionManager = plugin.getRegionManager();
Location minCorner = new Location(getServer().getWorld("world"), 100, 50, 100);
Location maxCorner = new Location(getServer().getWorld("world"), 110, 60, 110);
TriggerZone trigger = new TriggerZone("example_zone", minCorner, maxCorner);
trigger.addAction(TriggerZone.TriggerEvent.ENTER, new SendMessageAction("You have entered a zone");
regionManager.addRegion(trigger);

[lilac dagger]

totally fine to do the cast manually as optic did 😄

[torpid blaze]

true

[vagrant stratus]

You'd just store TriggeZone variable and pass that around w/o needing to cast every time

[lilac dagger]

but the game engine shouldn't care about game specific stuff

[vagrant stratus]

^

[ivory sleet]

for example, if u have some player data in a specific minigame, then just have a player data type for that minigame

[lilac dagger]

only enter point should be a generic method where you up cast

[torpid blaze]

well of course

[lilac dagger]

and that's all the generic you need

[vital umbra]

Lol. Well, I prolly actually have a problem with the last app I mate using unity. But that was months ago, and I can't remember much of the problems I had/fixed 😅

[torpid blaze]

ok, I will try. probably a lot easier

thanks

But for the GameState Enum I would need a type right?

[ivory sleet]

either way kess apps, you can think of generics as type constructions, you can have a list of ints and list of strings and they're different types

[torpid blaze]

that would only be one type so not that big of a problem ig

[ivory sleet]

you wouldn't want to create a list type for every other type yk

[lilac dagger]

polymorphism wins here too 😄

[vagrant stratus]

I mean, if the GameState enum isn't shit you don't need to polymorph or cast

[lilac dagger]

this is my impl of game state, i name them phases

this is in the base library and i can switch them up if a game needs something different

[torpid blaze]

don't quite understand. you can't extend a enum...

[vagrant stratus]

public enum GameState {
    CREATED,
    WAITING,
    RUNNING,
    ENDING,
    ENDED
}

Kinda covers everything you'd need for a basic GameState system

[ivory sleet]

I mean I do understand the idea of generalizing game states since different minigames might have different state machines

[lilac dagger]

yeah

an enum isn't enough

[torpid blaze]

similar to mine. but you don't have an enum too?

[lilac dagger]

i actually do for my auto join system

[vagrant stratus]

Aye, but you don't want to over complicate things if you don't know it has to be so complicated

[ivory sleet]

yea

[torpid blaze]

yea, but they change for every minigame in my situation. makes it cleaner I think

[lilac dagger]

this is what i have

[vagrant stratus]

Uh... why? A lot of those will be standard for every mini-game

[ivory sleet]

you might want to have external and internal game states then, like common game states you could probably expose to the api, but then each mini game might have a set of internal states perhaps?

[vagrant stratus]

State does not necessarily mean Phase

[lilac dagger]

yup

😄

[torpid blaze]

for endergames I have LOBBY, PREPARE_MAP, SPAWN, GRACE, PLAY, END,
but for getdown I have LOBBY, PREPARE_MAP, JUMP, JUMP_END, SHOP, DEATCHMATCH_PREPARE, DEATHMATCH, END

[vagrant stratus]

You might have a

public abstract class GamePhase {

  public abstract void onEnter();

  public abstract void tick();

  public abstract void onExit();

}

class, for example

[torpid blaze]

I think it is a bit cleaner when I do it this way

[vagrant stratus]

Two of those can be done better w/ internal handling, not states

You'd just have a GameType.DEATHMATCH and then use GameState

[ivory sleet]

Yea thats for the internal ones, but those are encapsulated more or less to each minigame, you might wna map
for example:
LOBBY --> PRE_GAME
PREPARE_MAP, SPAWN, GRACE, PLAY, --> RUNNING
END --> POST_GAME
and then let pre game, running and post game be for api where its shared for every minigame

[vagrant stratus]

Regardless they're implementing it from the very beginning really poorly

[ivory sleet]

yea, I do like the honest attempt with generic type parameters

[torpid blaze]

then I would have two state mashines inside another. not sure if that would make more readable

[vagrant stratus]

GameType & GameState are like the bare minimum

or perhaps turning it from an enum to a proper abstract class

public abstract class BaseGameType
{
  private GameState state;
  // Other variables

  // constructor & other code
}

[torpid blaze]

well, thats what I have

[vagrant stratus]

Which is one of the cleaner ways to do it lol

You're trying to over complicate things

Sometimes simple is better lol

[torpid blaze]

probably

thank you very much. I will try and simplify it a bit 😄

[ivory sleet]

here is where difficult choices come in play, you're going to have to choose between how complex you want your code base to be
what features do you find necessary? (from a library point of view and from a framework point of view)
when does it get too much for you (how simple do you want to keep it)?

[vagrant stratus]

for me personally the implementation is

public class BedwarsMinigame extends AbstractMinigame {
  public BedwarsMinigame(GameContext context) {
    // Context handles max players and stuff
  }

  // everything else
}

though you could do the following too

public abstract class AbstractMinigame { /* Code */}
public abstract class SingleplayerMinigame extends AbstractMinigame {
   private Player player;

   // Code
}

public abstract class MultiplayerMinigame extends AbstractMinigame
{
   private TeamManager teamManager;

   // Code
}

[torpid blaze]

👍

[vagrant stratus]

I'm not releasing my library though lmfao

Only part of it that I have released though is https://www.spigotmc.org/resources/triggerzones.132905/

[lilac dagger]

alright, keep your secrets 🥲

[vagrant stratus]

It's for my own server KEKW

oh and there's there too https://www.spigotmc.org/resources/actionlib.117241/

[topaz cape]

how do i tell if BlockExplodeEvent is caused by Wind Burst

[lilac dagger]

the only thing that comes to mind is on attack or interact if player used a mace with windburst to add it to add the player to a set, and on explosion check if said player is there

[topaz cape]

that sounds horribly hacky

[lilac dagger]

i can't think of a better way

maybe there's a better event

does explosionprimeevent triggers?

if so it has the entity who triggered the event, you'd only have to check the hand for a mace with wind burst

[topaz cape]

good question

let me check

but its an entity event and i highly doubt its called here

[lilac dagger]

worth a try

oh

there's EntityExplodeEvent

[topaz cape]

EntityExplodeEvent is not called

[lilac dagger]

ah

did you try explosion prime event?

[topaz cape]

still on it

[lilac dagger]

alright

still have a hope

😄

[ivory sleet]

btw @lilac dagger what kind of caching strategy do u usually resort to when u deal w lets say user/player data and state

[lilac dagger]

hashmap?

or for database stuff

it's the same for database too actually

[ivory sleet]

oh I more meant like write behind, write around etc

[lilac dagger]

i'm not familiar with the terms

let me see

i'll tell you how my system works in bedwars

[ivory sleet]

go for it ^^

[lilac dagger]

when the player joins their data is pulled from the database into local memory, after that when the data changes or needs to be sent i use a method like this to update the database

i'm yet to find time to do this system in frconomy

[vagrant stratus]

Yea, I just do it all in local memory & save on quit, disable, and every x amount of time lol

[ivory sleet]

ah nice, how do you deal w offline users for example? do u just serve them directly from a db request?

[lilac dagger]

that's how i did it in frconomy because vault doesn't have async callbacks

[vagrant stratus]

Good thing I don't use vault for my server LMFAO

[lilac dagger]

but i have a solution in mind

[ivory sleet]

vault is... vault yeaa

[mystic sky]

This is hard when you dont have java skills

[lilac dagger]

confirmation based transactions

[vagrant stratus]

I do though 😎

[mystic sky]

I'd say lot of plugins use vault dependency

[ivory sleet]

yea sadly so

[lilac dagger]

you try to send data once, and then it tells the user if it's not cached to try again in a few seconds

[ivory sleet]

or well I mean sometimes sadly so

[lilac dagger]

so the database has time to cache that data async

[mystic sky]

I avoid using vault and protocolib for example, but this is hard

[vagrant stratus]

I just have a simple

public class User {
  private UUID uniqueId;
  private BigDecimal balance = BigDecimal.ZERO;

  public (UUID uniqueId) {
    this.uniqueId = uniqueId;
  }

  // code
}

[vagrant stratus]

And I use 0 of them lol

[ivory sleet]

ah okay, but then even for offline users you'd cache the user for a short period of time in case of subsequent calls?

[vagrant stratus]

I code almost everything from scratch for my server

[lilac dagger]

of course

20 minutes by default sounds like a good amount

[ivory sleet]

yea, I mean luckily packetevents have become more standardised

[mystic sky]

I prefeir using NMS

[ivory sleet]

but vault is still a bridge many servers use

[vagrant stratus]

fuck vault lol

[ivory sleet]

yea but for packet listening it can be nice w packet events

[lilac dagger]

i'm actually gonna spend some time tomorrow to fix fr conomy

i really like that project :d

[ivory sleet]

:)

[lilac dagger]

it deserves some time and love

[vagrant stratus]

I'm privileged enough to just fork paper lol

#YayForBeingProgrammerNerd

[mystic sky]

If you are interested on that you can give a check to https://github.com/Winds-Studio/Leaf/

[vagrant stratus]

Don't need packet events when i can just add patches to paper lmfao

[ivory sleet]

yea

[umbral ridge]

why is vault so popular though, if you make your own system, you dont need it

[vagrant stratus]

Only use I'd have for Leaf is pulling patches

[ivory sleet]

its an eco system bridge

[mystic sky]

Well most of people does not know java as i've said

[vagrant stratus]

It's SUPER fucking old and used everywhere, which means it continues to get used

[mystic sky]

This implementation is cool, but folia exists too https://github.com/MultiPaper/ShreddedPaper

[umbral ridge]

whats an eco system bridge? i feel like this could be much simpler, economy at the end of a day is just a number and doesn't need 2 mb of code

[vagrant stratus]

Don't need that either

[umbral ridge]

you could do an economy plugin with api in a few classes and be done with it

why is vault so big

[vagrant stratus]

Gotta remember this is a plugin from 2011 @umbral ridge

It's old

[mystic sky]

Old plugin, gives api

[umbral ridge]

ohhh compatability

[vagrant stratus]

Times were different back then, which gave vault an edge which made it standard decade later lol

[mystic sky]

True

[ivory sleet]

because independent of what chat, permission and economy plugin u use, vault acts like an interface

[vagrant stratus]

Only use I have for paper forks is just pulling patches, and most servers won't even need Folia or a fork of Folia lol

[ivory sleet]

placeholder api, or any plugin that consumes economy balance

[vagrant stratus]

Also helps it's old as fuck. Roughly around the transition to BukkitDev, if not older

[ivory sleet]

true

[vagrant stratus]

It's simple. It's old as fuck. It's cemented as a core API and likely will be for years

[mystic sky]

same as protocolib or citizens by the way

[vagrant stratus]

Are there better libraries? Yes
Are they as supported as Vault? Hell no

It would take a lot for there to be a new standard library for that kinda thing

[umbral ridge]

I made my own system and didnt use any existing plugins, economy, permissions, ..

[vagrant stratus]

Similar situation to LP.
It's the most feature complete, pex died, groupmanager stagnated, and the other alternatives just aren't as good

[umbral ridge]

made a cool database hikari wrapper plugin

then built permissions and economy on top of it

its really cool

both perms and economy plugin have an api to events, methods etc

[mystic sky]

You have to put yourself in the shoes of someone who configures plugins and doesn't make them; they want something that works well and has support

[vagrant stratus]

Most of my stuff is custom, but I won't waste my time making a custom permissions system lol

[vagrant stratus]

Not important if it's private use, not public lol

[umbral ridge]

its really simple to make, but it works only with the custom system... i dont have intention of it working with any other plugin than mine

[vagrant stratus]

Almost all of my plugins are private, for example. This means I don't have to rely on third-party libraries and can make everything from scratch to properly suit my needs

[vagrant stratus]

They're really simple to make, yes. It's just not worth the time and effort personally, as LuckPerms has everything I'd need from a permissions plugin

[umbral ridge]

really simple..

[mystic sky]

To a certain extent, I see the point. Imagine having a completely customized server and being the only one who has to update it. It's crazy

Plugins like LP, WorldEdit, ViaVersion hell

[vagrant stratus]

Not really crazy, a lot of large servers are like that

[mystic sky]

With the difference that they're a team

[vagrant stratus]

Still makes no difference. How often do you think core plugins get updated lol

[mystic sky]

Still crazy

[umbral ridge]

that's kind of my dream

i own my plugins and the systems i have

[mystic sky]

I have several custom plugins, so for me it would be more of a nightmare

[vagrant stratus]

Debatable. I can make a moderation plugin and then never have to update it again

[umbral ridge]

i dont want someone elses work in my stuff

I make things

i'll make sure its good

[mystic sky]

I don't think you want a custom viaversion

[umbral ridge]

I dont need it

[vagrant stratus]

Then there's me. Too many plugins which do roughly the same thing.
Easier to just make my own stuff from scratch lol

[umbral ridge]

i dont need via version

or any of that stuff

[mystic sky]

Latest MC version?

[vagrant stratus]

That's the only version I support, personally lol

[mystic sky]

Because if you want multiple protocol support you will need it

[umbral ridge]

yeah the server is always the latest, and specific version only

if you dont wanna play or dont have that version... just dont play

[mystic sky]

That explains why you want all custom, imagine 1.8+ to latest

[umbral ridge]

yeah that would be a pain to do

i hate 1.8

[vagrant stratus]

You can do all custom even with ViaVersion lol

[umbral ridge]

item ids were weird

[vagrant stratus]

You'd just have a wrapper API or something

[umbral ridge]

no

i dont need viaversion

[vagrant stratus]

Never said you had or needed too, just saying it's possible lol

[mystic sky]

I love that version I played it for many years when I was a kid. I still maintain the 1.8 paper a lot.

[mystic sky]

hell ☠️

[umbral ridge]

use viaversion and make a wrapper around it?

they have an api?

[vagrant stratus]

For me personally, I could never work with anything lower than 1.13 for free lol

[mystic sky]

Yes

[umbral ridge]

EH

no more wrappers

[mystic sky]

I use it to display on name tags protocol version

[vagrant stratus]

I think that's the version where every item and block got its own material 🤔

[mystic sky]

xmaterials intensifies

[umbral ridge]

my next project is probably a kingdoms plugin... that will be fun :DD

also have to do custom npcs for town shops

that will be pain in the ass

[mystic sky]

I can recommend you ZNPCplus or FancyNPCS

[vagrant stratus]

Mannequins at least makes that easier lol

[mystic sky]

Both need 0 dependency

And are packet based

[vagrant stratus]

w/ it being private & custom, you can ignore any sort of compatibiltiy risks with public resources lol

[umbral ridge]

thank u i could take a look. but my goal is to make everything by myself so i know exactly how it works... because i have everything custom..

[vagrant stratus]

as previously stated lol

Just build off of Mannequins since you're on a version which has em

[umbral ridge]

how well does it work?

[vagrant stratus]

As long as you're not needing pathfinder goals or anything you won't have to use NMS or anything

[umbral ridge]

any bugs?

[vagrant stratus]

Don't believe so

[umbral ridge]

is it open source?

[vagrant stratus]

No, the actual NPC thing minecraft added lol

https://minecraft.wiki/w/Mannequin

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/browse/src/main/java/org/bukkit/entity/Mannequin.java#92

[umbral ridge]

oohh i didnt know about this

[vagrant stratus]

Yea, it's a 25w36a thing

[umbral ridge]

I need to think it through

i might need path goals

[vagrant stratus]

part of 1.21.9

[umbral ridge]

because i dont want the town to be dead

i want the npcs do to something

need to make a plan for it

[vagrant stratus]

In that case, you'd just hook into NMS and go about it as one normally does with pathfinder goals

[umbral ridge]

i haven't done nms for a long time

[vagrant stratus]

or if you're using paper then their ai goal thing. not that i know how to use it

but the new Mannequin is the better way to do it from scratch nowadays lol

[umbral ridge]

what takes most of the time is to make it customizable.. like.. little things.. i did a config class which auto synces values to its values class and has an event, when config reloads

[vagrant stratus]

w/o that you'll have to do it via NMS like Citizens and stuff

[vagrant stratus]

It takes a PlayerProfile and works the same as any other entity.

The only thing you'd have to add support for yourself if you're using spigot is pathfinder stuff

[umbral ridge]

im using paper because i like their Components

XD

[vagrant stratus]

Yea, then just learn their AI Goal api and you're golden most likely

[umbral ridge]

hmmm ill see how well its documented

ty optic

[vagrant stratus]

no clue lmfao

[mystic sky]

Probably you should use FancyNPCS is really easy with the api

[vagrant stratus]

They won't

they'd prefer to have everything from scratch lol

[umbral ridge]

I'm tempted to use it

I'll look at it over the weekend

the thing is, i like the process of learning new things... not just getting everything instantly

[mystic sky]

When I make a plugin or modification, it's usually because something is lacking, not because it's mine, at least in my case

[mystic sky]

That's a good point of view, but is a headache

[vagrant stratus]

Your best bet for this is Mannequin & Paper AI Goal API then lol

[umbral ridge]

its a good headache

XD

[lilac dagger]

the caching strategy in my minigames is write back

i write instantly to the cache and then send it asynchronously to the db

[vagrant stratus]

Mannequin#setDescription(String) // The "NPC" part of the name
Mannequin#setCustomName(String) // The player name
Mannequin#setCustomNameVisible(true);
Mannequin#setPlayerProfile(playerProfile);
Mannequin#setImmovable(true);

Bare minimum

[umbral ridge]

what about the pickaxe on the right near the oak log?

How do you do that

[vagrant stratus]

Invisible armor stand or something along those lines iirc

There are a lot of shenanigans with custom models and invisble armor stands and stuff

[umbral ridge]

yeah

[vagrant stratus]

THere's a plugin, somewhere in this discord which shows all that stuff. Lemme find it lol

Mod*

also https://modrinth.com/mod/server-pack-unlocker

[umbral ridge]

cool cool

eh, i was never a fan of resource packs

[vagrant stratus]

Yea, used that on a server to see how they do things. It's just item & armor stand shenanigans lol

[young knoll]

Skyblock doesn’t use one

Those items are just armor stands

[vagrant stratus]

see my previous messages lol

[umbral ridge]

if its armor stand.. I didn't know you can display an item on it

[vagrant stratus]

It's just holding the item & invisible

[umbral ridge]

ohhhhhh

[vagrant stratus]

You're just setting the location to something that looks good

[umbral ridge]

its an entity with an item but entity is invisible

[vagrant stratus]

Yes. It's just holding the item in one of it's arms, set to be invisible and unmovable, and positioned somewhere

[mystic sky]

Works with channel stuff? For example if i want to send to another server

[vagrant stratus]

Similar to how balloons and stuff work

[umbral ridge]

cool

[vagrant stratus]

This uses invisible item frames, items, and barriers + a resource pack

[umbral ridge]

can it cause lag?

fps drops?

[mystic sky]

Surely for bad hardware

[vagrant stratus]

As long as you don't over do it it won't

[mystic sky]

Any ways clients always can disable stuff

[umbral ridge]

Yeah

[vagrant stratus]

Better example lol

[umbral ridge]

cool stuff

[vagrant stratus]

Note the characters in the player name for the status & rank name as well

You can get real fancy with resource packs, albeit they ain't safe LOL

[umbral ridge]

yeah that's just a different symbol/character

or a resource pack i guess

[vagrant stratus]

resource pack + character in a language you'll never use + other stuff

[umbral ridge]

I need to rewrite my nametags functionality... planning to use TextDisplay and don't use teams at all

[worldly ingot]

Better, in a font you'll never use

[mystic sky]

Unlimited Name tags similar stuff

[umbral ridge]

and also use the packets a little

[worldly ingot]

You can provide a font in components, which you should do instead of replacing the vanilla font characters

[vagrant stratus]

You can see the full thread here https://discordapp.com/channels/690411863766466590/694661573125472256/1101563685689884713 lol

[young knoll]

You should but spigot doesn’t have good api for that

[mystic sky]

He's using paper

[umbral ridge]

https://cdn.discordapp.com/emojis/723936238993801257.gif?size=96&quality=lossless

[young knoll]

If only there was a PR to add component support to everything that wasn’t dead

[worldly ingot]

If only

[sly topaz]

I honestly don't understand why that PR is dead

[mystic sky]

[vagrant stratus]

I don't even know what's on the JIRA lol

OH choco did anything come about when it came to our talk about implementing that random teleport api lol

[sly topaz]

the only negative review it got was MachineMaker's comment about the bad interopability with the old methods

[worldly ingot]

Yeah at which point I gave up

[vagrant stratus]

I already had the RIP prepared for that reaction LOL

[sly topaz]

I don't believe that was enough to just disregard merging the PR, but welp

[worldly ingot]

I don't either

[vagrant stratus]

how many dead prs are there xD

[sly topaz]

well, some are dead with actual reasons, this one in particular just got enough friction in it to leave it in the limbo state that it is now

same deal with the material to itemtype/blocktype conversion

[vagrant stratus]

https://tenor.com/view/dance-coffin-meme-rip-gif-16909625

one day we'll get a modern itemstack api

https://tenor.com/view/skeletor-one-day-mad-pissed-gif-16945426

[wet breach]

just fyi, clients can use jvm arguements/flags just like the server does. Should play around with these as they do in fact help the client more than you think 😉

[rotund ravine]

If you just heard of client flags you should leave it as default. You won’t be able to do better than default without proper knowledge, even if your skript is 1 thousand lines long

[ivory sleet]

yea didnt they recently change the vanilla client to run on gzgc or also

or well not recently

but not too long ago

[merry swallow]

where do i access the legacy version of https://hub.spigotmc.org/javadocs/spigot/index.html ?

[chrome beacon]

That's still in the snapshots so pretty recent

[ivory sleet]

oo right right

[chrome beacon]

Help chat has them

[merry swallow]

oops sorry

[chrome beacon]

With helpchat I mean the website

https://helpch.at/docs/

[merry swallow]

found it , awesome

[young knoll]

Wasn’t gzgc made the default in a certain java version

[ivory sleet]

iirc generational mode by default

for zgc

[chrome beacon]

G1 is still default as far as I'm aware

[ivory sleet]

yea

oh well would u look at that, j24 seems to have removed non gen mode for zgc

[fading drift]

is there a way to determine what world a player joins when they join a server before theyre sent to the world

[summer scroll]

Maybe you can use PlayerSpawnLocationEvent

[fading drift]

yes thank u

I have a duels server that has a couple of duels, and each duel requires some different login in some listeners. is there a smarter way to go about this rather than checking what duel the player is in in each listener. I feel like this isnt expansive as the listeners would just become slabs of code growing with each new duel type.

I am thinking about having a sort of "ClassicDuelListener", "UHCDuelListener" etc class, or is this overengineering?

[buoyant viper]

no such thing as overengineering

simplicity is your enemy

[drowsy helm]

The performance difference will br negligible, but from a clean code perspective you should have separate listeners

Separation of concerns

[thorn isle]

doesn't make a difference performance wise

at least not on paper where they do evil asm bullshit rather than reflection for calling eventhandlers

on spigot there might be a difference you might be able to measure with a microbenchmark harness or something, it would indeed be negligible

[slender elbow]

huh

[thorn isle]

yeah you generate classes/bytecode at runtime to directly call eventhandler methods, while spigot does it reflectively

or did you both switch to methodhandles now?

[slender elbow]

pretty sure we replaced all that asm bs with a much simpler constant methodhandle approach

spigot still uses a non-constant foldable Method afaik

yippee

[buoyant viper]

lambdametafactory bs my beloved

[thorn isle]

i didn't really mind the asm nonsense but i remember someone complaining about it

i guess it did allow billy to create his EntityMoveEvent without killing the server just with the reflection overhead

[slender elbow]

nope

[slender elbow]

the problem is that the code was all over the place, difficult to read and all that

the current code should be at least just as fast

and is far simpler

[thorn isle]

yeah probably not nice to maintain

[slender elbow]

there were straight up whole classes of dead code

it was so funny

[buoyant viper]

sadge

looking at it now

similar-ish approach for using LMF but more interesting, never seen defineHiddenClassWithClassData

[short pilot]

public void onPlayerMove(PlayerMoveEvent event) {
    if (event.getFrom().getBlockX() == event.getTo().getBlockX()
        && event.getFrom().getBlockY() == event.getTo().getBlockY()
        && event.getFrom().getBlockZ() == event.getTo().getBlockZ()) {
        return;
    }
}

[slender elbow]

thank you

[buoyant viper]

?paste

[undone axle]

Looking to paste something? Try a code block or one of the following websites:

• https://pastes.dev/
• https://sourceb.in/
• https://mclo.gs/ (best for server logs)

[buoyant viper]

https://pastes.dev/KHIYgEtNP6 this aint exactly the prettiest it could look, but lambdametafactory ftw

both basically give u a POJO that gets called rather than a reflect call ig

based on an event bus that isnt as strict about input types however, iirc lmf is picky about param types otherwise

[short pilot]

asm sounds nostalgic

[grave sandal]

Hello there, i am sorry for this request, this is not publishing or advertisement i am just looking for someone can help me

[umbral ridge]

is there an event when that happens or is that totally client side? when glass attaches to blocks next to it

[grave sandal]

I know basics but very basics of java and I am interested at learning how to make plugins... at the moment i am looking at a developer teacher can teach me how plugins works and how to give a structure to those, because i am a beginner i had in my intention to pay for those lessons

For more info please just direct message me, and I thank you all for your availability

[chrome beacon]

Try the BlockUpdateEvent

or whatever it was called 💀

[umbral ridge]

nice

there isnt one

[worldly ingot]

BlockPhysicsEvent

[chrome beacon]

^ that's the one

though might not work 🤷‍♂️

[umbral ridge]

great

[worldly ingot]

Just be careful with what you do in that listener. It's called very often

[umbral ridge]

idk if glass connecting to the block next to it is considered a physics

but ill try

[worldly ingot]

I believe it's "physics" in the Minecraft world :p

[umbral ridge]

hahaha right

[lilac dagger]

i'm really close to making an async economi api

vault api just doesn't cut it

it wants data now

doesn't matter if it's in a blocking database

🙁

[ivory sleet]

and just falling back to 0 whilst loading isnt an option?

[lilac dagger]

there's also has account checks

with no way for players to know

that they have to wait a bit

if there's an offline player shop

this would be annoying

there's withdraw and deposit with an economy respone

where i could embed a message to wait

but if the plugin does if economy.has first

[worldly ingot]

Tried to get one natively into Bukkit. Problem isn't making an economy API, the problem is getting economy plugins and API consumers to adopt it

[lilac dagger]

there's no way to let players know

[lilac dagger]

i'd adopt it tomorrow

i have already made the futures

[lilac dagger]

I think i'll implement 2 vault hooks

One that's blocking and one that you can click twice to buy

And let users choose which one they want more

Also about caching offline players i have to worry about players on a different server being online with a changing balance

In mysql mode

[thorn isle]

vault really doesn't lend itself to anything blocking

i you can, i would recommend just writing against your eco backend/plugin directly

[umbral ridge]

good

ill just cancel everything

XD

[thorn isle]

clearlag "stop-lag" mode in a nutshell

[onyx fjord]

actionbar native api would be nice to have in bukkit

the issue has always been action bars overriding themselves

lets say you have a 24/7 actionbar with some stats

but another plugin sends a notification thru actionbar

next tick its gone

bukkit could have a priority based system

[ivory sleet]

similar to hide/showEntity where u pass in the plugin instance?

[onyx fjord]

similar goal

but it would require priority like events

[thorn isle]

this would definitely be nice

currently i end up jerryrigging this through protocollib

[echo basalt]

I designed a system like this at work a few years ago

[thorn isle]

it's not very complicated to make happen, issue is mostly adoption; without bukkit forcing developers to register their things with priorities, you have to fall back either with external priorities based on regex or callsites, or treat all plugins not explicitly opt-in as "normal" priority

[ivory sleet]

yea

speaking of adoption, has it ever been brought up as an issue or pr to add async support to vault?

[thorn isle]

probably

but vault is "feature complete"

so it probably isn't ever going to happen

they've been fighting over explicit UUID support for years

[ivory sleet]

:,)

[lilac dagger]

All they had to do is provide an AsyncEconomy interface and deprecate the current one

People would've implemented both and eventually switched to async economy

[sullen marlin]

Is that much different to the caller just running it async though?

[lilac dagger]

The issue is some plugins would still use the old interface

As a economy provider i guess it makes sense to have support for both for a while

An economy caller should definitely be async only

[thorn isle]

the main issue with vault is it doesn't offer any kind of transaction api

it's not an issue with just threading, but also logging and moderation

you can't have a "x paid y to z", you'll have a "x paid y" and "z received y", which you have to stitch together manually

[echo basalt]

didn't vaultunlocked support it

[thorn isle]

neverheard of that

which is kind of the problem; adoption

[echo basalt]

https://www.spigotmc.org/resources/vaultunlocked.117277/

[thorn isle]

vault poisoned the proverbial well with the minimum viable product and now we're stuck with it forever

[echo basalt]

ah no VaultUnlocked is mostly for uuid & bigdecimal

no async

but there are some async econ plugins

[slender elbow]

also yeah, floats, yikes!

[grave abyss]

is NMS like mixins but for plugins? i cant understand it

[vagrant stratus]

no

NMS is the minecraft code itself, no mixins or similar

[grave abyss]

so with NMS i can modify the minecraft code?

-# also enable ping reply

[lilac dagger]

yes

you can do almost everything

sometimes reflections are needed to access private methods and fields

but it can be done

[grave abyss]

oh okay

thanks guys!

[vagrant stratus]

Unless you fork spigot or paper, in which case you can just edit it directly & recompile lol

[lilac dagger]

too much work

[vagrant stratus]

depends tbf

w/ me doing a server with 99% custom plugins, forking it makes things easier lol

[young knoll]

I mean you can’t actually modify the vanilla code

[slender elbow]

well not with that attitude

[young knoll]

You can mess with variables, and hook into certain things, but there’s no equivalent of mixins with spigot

[shadow night]

well...

I have created something like a mixin into code that isn't mixinable when working with neoforge
and I am fairly certain that same trick could work with spigot

to some degree

[young knoll]

What

[vagrant stratus]

Sure, in regular plugins lol

[slender elbow]

what is a "regular" plugin? and what is an irregular plugin

[wet sinew]

In these NMS packages, each version is installed in my local repository and has jars. When I try to set the scope to system, none of the jars work, and ChatGPT tells me that this won't work. It tells me things I don't understand, like multi-module. I'm new to NMS. I'm not sure how to create NMS's between 1.16.5 and 1.21.11 in a single jar. and load or run the NMS accordingly in a single JAR file.

But this is when your plugin or an server issue?

[wide cipher]

Is there a way to hide the saddle and like leash from an invisible horse? cause i want the player to ride an ball of air, but the saddle is still visible.

[mortal vortex]

Why use a horse though

[wide cipher]

inbuilt jumping mainly

is there a different way you would suggest?

[mortal vortex]

A slime idk

[sly topaz]

for the saddle you can probably send an equipment change

for the leash I think since those are now entities, you can just hide the leash entity?

maybe not with the API tbh

[sullen marlin]

I mean you can do both the above with the api

[buoyant viper]

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

[buoyant viper]

is it possible to open the enderchest inventory without needing an actual enderchest near the player?

i see HumanEntity#getEnderChest is just an Inventory that should be useable for HumanEntity#openInventory so like id assume yes right

[sullen marlin]

yep

Like 600 first plugins do that

[vagrant stratus]

too common infact lol

If there's an inventory, there's a plugin that lets you open it without needing the actual block lmfao

[solar slate]

Does anyone have tips for storing/sending complex command usages? It's become quite tedious with some of my plugins

[buoyant viper]

figured lol

[quaint basin]

How can I listen to a packet using nms?

[chrome beacon]

Use PacketEvents or ProtocolLib

it is not worth reinventing the wheel

[quaint basin]

https://pastes.dev/ktOhH0SaDu I received a tutorial on how to do what I want with NMS, and I think it's easier to do it with NMS than with Packet Events

[chrome beacon]

hm? What are you trying to do

Why are you messing with chunk lighting

and chunk packets

[quaint basin]

I have a Skyblock-gamemode server, but instead of islands, it's a normal world with borders; it's one world per player, and I'd like chunks outside the world's border to be intercepted with fake chunk data; so, instead of the world being 300x300 for example, it's 200x200 for example, and this way I use less disk space

The player cannot go to or interact with the chunks, so there won't be bugs like the player flying etc

[chrome beacon]

You can just stop the chunks outside the border from saving to disk

[quaint basin]

And how can I show a 300x300 world to the player, but only save to the disk as 200x200?

https://imgur.com/a/HzdQ8vX I also tried using packetevents but I can't send a chunk from bytes

[thorn isle]

you can either hold those chunks in memory (which is going to be a lot of memory), or recreate them on the fly whenever you need to send a chunk packet (only really feasible for superflat style worlds)

since you're doing skyblock, i assume you'd want them to be sent as air-only chunks, which should be very easy

however, in practice i don't think this is going to make any reasonable difference in disk usage, since air-only chunks are also extremely small on disk

[quaint basin]

It's not a normal skyblock; it has the idea of ​​a skyblock but it's a vanilla world with borders so they aren't air-chunks

[thorn isle]

well you're going to have something to send

if it's a regular vanilla chunk with trees and carvers and shit, recreating that from scratch on chunk send is going to be infeasibly expensive

[quaint basin]

https://imgur.com/a/JxV86Ra

smth like that

[thorn isle]

yea no you're not generating that on the fly for each packet

[chrome beacon]

^ better off storing it

[thorn isle]

you need to generate them ahead of time and store them either on disk or in memory

if you have multiple worlds/servers with the exact same out-of-bounds chunks, you could store the chunk packets themselves in a database/file shared across them all to reduce disk usage

[quaint basin]

https://pastes.dev/ktOhH0SaDu Does this solution generate every time it loads? I didn't understand this solution, that's why I'm asking

[thorn isle]

mcWorld.palettedContainerFactory().blockStatesContainerCodec.parse<Tag>(NbtOps.INSTANCE, Converter.convertTag(section.blockStatesTag)).getOrThrow()

this parses it from nbt

the nbt would presumably come from the disk

it doesn't magically generate a full chunk with all blockpopulators and everything applied

otherwise initialize them as empty: PalettedContainer(Blocks.AIR.defaultBlockState(),mcWorld.palettedContainerFactory().blockStatesStrategy(), null) and PalettedContainer(biome.get(Biomes.PLAINS).orElseThrow(), mcWorld.palettedContainerFactory().biomeStrategy(), null)
this creates an empty chunk

i.e. air only

[thorn isle]

so the first one would be what you would use for this

but unless the file/nbt is shared across multiple worlds or servers, there is no point to doing it over just having the chunks saved in region files normally

[quaint basin]

wdym with this

[thorn isle]

i quoted two parts of the paste

and replied to something i suggested

i mean you would use the first part of the paste that i quoted to do the something i suggested

[quaint basin]

From what I understand, you're saying to have a template world where the chunks outside the border will be shared between all worlds, and the per-player world doesn't have those chunks in the file. The problem is, I have no idea how to do that

[thorn isle]

you use this to create a chunk from nbt

you store the nbt in a file, in a database, or whatever

then you send it in the chunk packet

[quaint basin]

But in this way, am I not generating the chunks every time they are loaded?

[thorn isle]

no, you are loading the already-generated chunk from disk

you are still parsing it which is not free either, but is much cheaper than generating it

[quaint basin]

Well, I'm lost. I don't even know how to listen to a packet with NMS, lol

[thorn isle]

you listen to player join and inject a netty stage into their netty pipeline

but like someone else said, there's no need to reinvent the wheel; just use protocollib or packetevents and get the packet handle from them

[quaint basin]

But that doesn't make sense to me; if I need to inject into the playerjoinevent to listen for packets, then how do I listen for packets before the playerjoinevent is processed?

All the code I sent you uses nms, and with packetevents it's completely different

[thorn isle]

unless you specifically need to put your packet listener at a particular spot in the pipeline e.g. after packets get turned into raw bytes, or before viaversion, there's zero reason to do netty shit on your own, and you should use existing solutions like protocollib or packetevents

again, you can get the nms packet handle from protocollib and packetevents

and use them with nms code

[thorn isle]

anyway, doing this at all is predicated upon this ^ being true

i take it since you're still going for it that it is?

i.e. you have many worlds/servers with the same out-of-bounds chunks

[quaint basin]

yea they are shared

the world is the same for everyone

[thorn isle]

right

[quaint basin]

how can I do this with packetevents?

[thorn isle]

i don't know, i've never used it

with protocllib you just PacketContainer::getHandle, and cast to the nms packet you want

[quaint basin]

Do you have any idea what I might be doing here?

[thorn isle]

the only annoying part is the that PacketType names don't line up with mojang or the wiki or anything sensible so it's a bit of a guessing game

[quaint basin]

In my head, this code makes sense, but for some reason it doesn't work

[thorn isle]

is that bytebuf for the entire packet or the block data

because the nms packet has a byte[]/bytebuf for the block data, and heightmaps and other shit stored separately

i also don't think you can just reuse the same bytebuf like that

have you worked with bytebufs before? they're not exactly like byte arrays; they have read and write indices

[quaint basin]

Are these bytes not enough to send a chunk packet?

[quaint basin]

no

[thorn isle]

to reuse it, clone it and pass a mirror/slice to the future packets instead of the clone

[quaint basin]

But I know that they kind of have indexes and advance something like that

[thorn isle]

i don't know, that's what i'm asking you

[quaint basin]

oh

[chrome beacon]

Just let the chunk be

[quaint basin]

i think is the entire packet

[chrome beacon]

It's not worth messing with

[thorn isle]

one issue i guess is happening here is that the sendPacket(buf) reads the buffer to the end, so after sending that buffer once, it will have no bytes left in it and any future attempts to send it will send nothing

[quaint basin]

This getFullBufferClone method is present in all packets, so I imagine it is entire packet

[thorn isle]

should be then

in that case try fixing the bytebuf issue and it might work

[quaint basin]

I've already tried 1001 different things xd

[thorn isle]

when you get the bytebuf from the first packet, clone it before assigning it to the field

otherwise, when netty reads it, it will be empty

and when passing it to new packets, mirror it; otherwise the first sent packet will again empty it

mirror basically creates a "view" into the buffer, sharing the underlying data, but having its own read/write indices

clone copies the data as well

[quaint basin]

if (buf == null) { ByteBuf buffer = (ByteBuf) event.getFullBufferClone(); this.buf = buffer.retainedDuplicate(); BoxPlugin.plugin.getLogger().info("v2 chunk loaded by first time"); } else { event.setCancelled(true); buf.readerIndex(0); event.getUser().sendPacket(buf); BoxPlugin.plugin.getLogger().info("v2 fake chunk sent"); }

[thorn isle]

you might want to rather than cloning it, copy it manually into a heap bytebuf or you might run out of native memory

[quaint basin]

i alr tried with readerIndex too

but is the same thing

[thorn isle]

pass a .slice() or something instead of changing the index manually

[quaint basin]

i'll try this:

if (buf == null) { ByteBuf buffer = (ByteBuf) event.getFullBufferClone(); this.buf = buffer.retainedDuplicate(); BoxPlugin.plugin.getLogger().info("v2 chunk loaded by first time"); } else { event.setCancelled(true); event.getUser().sendPacket(buf.slice()); BoxPlugin.plugin.getLogger().info("v2 fake chunk sent"); }

https://pastes.dev/zy6pGWgW10 this code results on this

[thorn isle]

what's the writer index on the buffer before you copy/slice it?

[quaint basin]

16:19:24 INFO]: [box-plugin] readerIndex: 0 | writerIndex: 1

[umbral ridge]

hey

what api for voting do you guys usually use?

i just wanna detect votes

i haven't done this for awhile so im asking, i used to use nuVotifier or something, idk if that's still an ok thing

[chrome beacon]

It's probably still NuVotifier

[round finch]

i wonder how i prevent these internet packets

[chrome beacon]

Time to start banning ips

[round finch]

i try!

they use proxies to send incorrect data to fuck with my server

[chrome beacon]

There's not much you can do about that

[round finch]

i need to filter it out
sorry im slightly venting here

[chrome beacon]

Building a filter is doable

but a lot of work

[round finch]

i managed to block vpns on ping

still annoying anyway thank you

[umbral ridge]

you can block them by hiding behind a proxy

proxies dont understand that kind of information and therefore ignore it

[round finch]

ah

[umbral ridge]

well

they dont reeaaally ignore unknown packet info

but yeah i use velocity as proxy

i used to have TCPShield

[round finch]

thanks for suggestions man!!

👍

it could save me some time

[umbral ridge]

these are generally harmless and cant do anything to your server

i never played around with netty much but if you really want to dig deep you could make a netty channel handler

you could inject into netty pipeline before wellll ... minecraft decoding

[umbral ridge]

is there a php nuvotifier api? if you wanna make a voting site?

i found some but they all seem to be almost a decade old XD

[chrome beacon]

Probably still work

if not make your own https://github.com/vexsoftware/votifier/wiki/Protocol-Documentation

[umbral ridge]

made my own

but im getting issues, ill fix it XD

HI OPTIC

[vagrant stratus]

HELLO

QUESTION

[umbral ridge]

I FIXED IT

WORKS CAT-PERFECTLY

[vagrant stratus]

Think Minecraft's AI impl is good enough for modern games, or is there a more modern (or just generally better) apporach to implementing it? I'm making a game & need to know lol 😎

[umbral ridge]

is good enough 😎

[chrome beacon]

Depends on the game you're making tbh

[thorn isle]

take a look at finite state machines and behavior trees

those are the two industry standards

[chrome beacon]

^

[vagrant stratus]

I was just gonna yoink MC's impl if it was good enough for modern games LOL

[thorn isle]

the new brain system is kind of like a behavior tree

using it is fine if you're familiar with it

[vagrant stratus]

https://tenor.com/view/i-guess-well-see-clarence-thomas-saturday-night-live-we-shall-see-its-to-be-determined-gif-25522836

[umbral ridge]

that's pretty cool now

[vagrant stratus]

Remembered I have a bunch of game dev/design books. Gonna hope at least one of them goes into the AI stuff KEKW

[chrome beacon]

I mean if you want to learn about behavior trees you can watch this https://www.youtube.com/playlist?list=PLFQdM4LOGDr_vYJuo8YTRcmv3FrwczdKg

[lilac dagger]

I'e got this book that i haven't yet read

It's by joshua bloch, i see him often as an author in the impl of the standard java lib

[chrome beacon]

That's a nice book

Covers many good things

[lilac dagger]

Yup 😄

[chrome beacon]

Concurrency in practice is also a good read

[lilac dagger]

I want to get head first java patterns

But it's a bit too expensive

Design patterns

Not java patterns

[lilac dagger]

I'll try to give it a try when i can

[vagrant stratus]

physical books? ew

[lilac dagger]

The feel of paper tho

It's unmatched

[vagrant stratus]

Too much $$$$

[lilac dagger]

Well digital ones are still very expensive

A bit less i think but still

[vagrant stratus]

https://tenor.com/view/that-is-saving-money-joseph-germani-thats-how-you-save-money-that-is-how-you-can-reduce-your-expenses-gif-26966020

Had a look at the old MC AI impl and it's simple enough ig
I should have books that go into other methods, but if anything I can yoink that & ignore the brain impl lol

[lilac dagger]

Yeah

Goal selectors and target selectors go brr

[vagrant stratus]

I could use the Brain impl, but I'm doing this in C++ and that's abstracted to hell and i don't wanna figure that mess out in C++ KEKW

[lilac dagger]

A few buffer overflows never hurt anyone

[vagrant stratus]

I mean ig the Brain could be massively simplified too if it's just kept to has/doesn't have memory 🤔

[lilac dagger]

Yeah of course

Depends on how much functionality you need

There's activities, memories

Not sure it's that hard to come with your own version

[vagrant stratus]

Yea, not really that difficult really

If I have a book that goes into it, I'll use that as a base instead kekw

So far, no LMFAO

[lilac dagger]

i'm pretty sure you can find enough online if you want to save money

path finder

math to look at stuff

and then use those in your brain recreation to give activities to entities

[vagrant stratus]

we'll see what happens lmfao

if anything, ChatGPT's got my back LOL

[umbral ridge]

OpticFusionGPT

[vagrant stratus]

$1000/question

[umbral ridge]

XD

[vagrant stratus]

😎

[umbral ridge]

I'm so happy with this, always wanted to do it, but i was on shared hosting before, couldn't do it

im on vps with root access now

THE best part comes now, making an actual plugin lol

[chrome beacon]

There are plenty of existing ones

[umbral ridge]

no

fuck them

XD

I'm making my own, everything custom

Most of my plugins are much more customizable than existing ones

[vagrant stratus]

each question gives me many snacks KEKW

[umbral ridge]

https://giphy.com/gifs/cats-funny-cat-67-MpnzrE4XcVQKcQf4kc

[lilac dagger]

i still think you should use some public plugins

making everything yourself means you don't have as much time to actually make sure all the features are top quality and bug free

[umbral ridge]

i take the time with my plugins because i love making them

[lilac dagger]

alright then 😄

[umbral ridge]

minecraft offers creativity which i like

XD

right now im thinking where i put my weighted random generator

because

[lilac dagger]

does it use a treemap and a range from 0-1 or 0 to 100?

[umbral ridge]

i dont remember wait

need to find it

[vagrant stratus]

+1 question = many McRibs 😎

[umbral ridge]

+1 free antimalware check

[vagrant stratus]

tbf some plugins just don't need that much debugging or testing

[vagrant stratus]

Nah that'll probably be an invoice at some point considering how much time it can take up lol

[umbral ridge]

XD

[umbral ridge]

i made it for a fishing plugin a few years ago and idk where the plugin is

[lilac dagger]

it has to be somewhere

[vagrant stratus]

well it's true lmfao
That can take ages if it's not a quick scan or check lol

It's usually not even a single plugin, but an entire server's worth

[umbral ridge]

idk where it is

nowhere

[lilac dagger]

🙁

[umbral ridge]

no fishing

[lilac dagger]

search for 'fishing' in files ont he whole computer

might be misplaced somewhere

[vagrant stratus]

Not sure how I'd price the checks though 🤔

[umbral ridge]

not found anywhere... might be on other hard drive

i shouldn't get too distracted...

[vagrant stratus]

I think I have a weightedrandom impl actually lol

[umbral ridge]

i might end up looking for it for an hour

[umbral ridge]

give xD

[vagrant stratus]

gotta wait KEKW

[umbral ridge]

ok ill smoke in meanwhile

XD

[vagrant stratus]

Waiting on Everything to update it's DB

so much better than windows search KEKW

[umbral ridge]

i know linux, but im more used to windows

i do have a mc server and sql server on linux though

[vagrant stratus]

https://www.voidtools.com/downloads/

this lol

[umbral ridge]

XD

ai is everywhere now

[lilac dagger]

i just made one, not sure if it works tho

[umbral ridge]

ty

looks cool

[lilac dagger]

yup 😄

[vagrant stratus]

Mine's a bit more complex than that. Mine supports weighted lists and stuff lol

[umbral ridge]

very nice

[lilac dagger]

weighted list?

[vagrant stratus]

GIVE IT A SEC

[lilac dagger]

cleaned it up a bit 😄

[thorn isle]

this implementation won't work

[lilac dagger]

hmm, what's wrong?

[quaint basin]

PlayerToggleFlightEvent can be called on SURVIVAL mode?

[thorn isle]

you're using the weight as the key, meaning if you have two entries with the same weight, one will override the other

[lilac dagger]

oh

that does sound like an issue

just make a list t then

and then randomly select from the list one element

[thorn isle]

similarly, if you have two entries with weights 0.9 and 1.0, the actual chances to roll them will be 90% and 10%, where you would expect them to be the other way around

the way you make it work is you make the key cumulative

[lilac dagger]

i'll fix them up now 😄

[thorn isle]

for any given entry e with the weight w, you want there to be an exact span of w from its key to the previous key

double weightCumulative = 0.0;
for (var e : map.entrySet()) {
  treeMap.put(weightCumulative, e.getValue);
  weightCumulative += e.getKey() / totalWeight;
}

however, there is another issue, which is that the Map<Double, T> you're taking as a parameter will also cause two entries with the same weight to override one another

so you should switch it to Map<T, Double>

[lilac dagger]

okay, one moment 😄

[quaint basin]

How do I know if a player is pressing two jump keys as if they were going to fly in survival mode?

[thorn isle]

enable the flight capability for them and cancel the toggle fly event

note that this will be ass with high latency

[quaint basin]

have some another alternative?

[thorn isle]

you could try the PlayerInputEvent or Packet

but i don't know if the client reports spacebar inputs midair

worth a try i suppose

[quaint basin]

they report if they are creative mode for sure

now on survival idk

[umbral ridge]

pretty cool XD

cool stuff

[lilac dagger]

okay, here you go 😄

i didn't test this either

[quaint basin]

what's site wtemplate

[umbral ridge]

no templates i made it myself

[thorn isle]

i think you might've misread what i said a bit

[quaint basin]

it is good but

ur vote site is famous?

[thorn isle]

the issue is with the math of how you're building the weights map

[quaint basin]

because vote systems are advantageous if they are famous

[umbral ridge]

im making this for myself

[thorn isle]

it doesn't result in the correct probabilities

[umbral ridge]

XD

[quaint basin]

for ur server ?

[umbral ridge]

yes
