[tender shard]

huh weird, no clue

[sterile token]

i will try to look at the java versions

i have installed java 17, but i dont think thats causing the issue

[dry hazel]

alternatively you can disable the epoll with use-native-transport in server.properties, don't know whether it'll have a measurable performance impact

[sterile token]

right thanks, i will try that

[tender shard]

spigot 1.16.5 won't even start using java 17

[sterile token]

okay, this definitly not okay

not sound as troller but the server is starting with no problem

just start to spam the stracktrace when pinging or trying to connect the server

[tender shard]

java -version

[sterile token]

there is no way server starts from what you said before

[sterile token]

okay this is not okay

no idea for sure whats happening

[tender shard]

btw 9fb885e-af1a232 is latest 1.16.5

you're using some other version?

[sterile token]

oh lmao im too stupid

i upload the wrong spigot

[tender shard]

yeah isn't that a 1.8 verison?

[sterile token]

yeah lmao

that why it was starting but no giving any version message

okay, know not understanding why is not being server executed with path specified

[tender shard]

?

[sterile token]

really thanks mfalex, i already figured everything. I appretiate your help as always you helping me

[sterile flicker]

is it possible to create several custom data models in a resource pack for one item? I now have several items that contain a custom date model, is it possible to make only one item, for example, a stick, have several models and the texture of the item itself, as in my case, was not broken

for example

{
  "parent": "minecraft:item/generated",
  "textures": {
    "layer0": "minecraft:item/stick"
  },
  "overrides": [
    {
      "predicate": {
        "custom_model_data": 1
      },
      "model": "ak47/ak47"
    }
  ]
 "overrides": [
    {
      "predicate": {
        "custom_model_data": 2
      },
      "model": "mp5/mp5"
    }
  ]
}```

[shadow night]

Hmm

Maybe you should not make two "overrides" sections

[sterile flicker]

but even if it is possible, why is the stick texture itself broken?

[sterile flicker]

And then what?

[shadow night]

The overrides is an array, but your second override there

I bet the reason for thr Stick breaking is an invalid model json

[sterile flicker]

if model is invalid, then why is the stick with custom model data displayed correctly

[halcyon hemlock]

smash

[shadow night]

¯_(ツ)_/¯

Well, you also forgot a comma after the first overrides array

[sterile flicker]

I see a problem.

[shadow night]

Yes, you have two elements with the same key in your json and you also forgot a comma

[sterile flicker]

I have to add to the atlas texture of the item itself right?

    minecraft:textures/atlas/blocks.png:minecraft:item/white_wool```

[halcyon hemlock]

smash

[shadow night]

The atlast texture? Man, you should make a correct model file first

[halcyon hemlock]

md_5 smash

[sterile flicker]

{
  "parent": "minecraft:item/generated",
  "textures": {
    "layer0": "minecraft:item/stick"
  },
  "overrides": [
    {
      "predicate": {
        "custom_model_data": 18
      },
      "model": "ak47/ak47"
    }
  ]
}```

[shadow night]

Also, as far as I'm aware thr atlast stuff is done automatically

[sterile flicker]

I have the right one, I don't see any mistakes.

where ,

?

[shadow night]

You had two overrides before

[sterile flicker]

I showed this as an example to ask if it is possible to do this

But I don't have it like that

[shadow night]

Hm

Well, the right thing would be to add a new element to the overrides array with other custom model data values and another model location

[sterile flicker]

Honestly, I didn't understand anything from your words.

you mean

"overrides": [
    {
      "predicate": {
        "custom_model_data": 18
      },
      "model": "ak47/ak47"
    },
    {
      "predicate": {
        "custom_model_data": 2
      },
      "model": "mp5/mp5"
    }
  ]```

?

[shadow night]

Yeah

[halcyon hemlock]

ak47??

[shadow night]

That should work, as far as I'm aware

[sterile flicker]

and what about the problem of the broken texture of the item itself

[shadow night]

No idea what could cause that

To me the file looks fine

[wooden frost]

Hello, could anyone help?
Im trying to make a tnt stick that can be ignited using a flint and steel. Because it is imposible for me to make it unstackable, i made the tnt stick change its state from ignited to non ignited when thrown, while working on it, i noticed that it runs both of these functions at the same time.

public static void playerInteract(PlayerInteractEvent e)
    {
        World world = Bukkit.getServer().getWorld("world");
    if((e.getAction()==Action.RIGHT_CLICK_AIR||
            e.getAction()==Action.RIGHT_CLICK_BLOCK)&&
                e.getPlayer().getInventory().getItemInMainHand().getType()==Material.SCUTE&&
                    e.getPlayer().getInventory().getItemInMainHand().getItemMeta().getCustomModelData()==1&&
                        e.getPlayer().getInventory().getItemInOffHand().getType()==Material.FLINT_AND_STEEL)
        {
            e.getPlayer().swingOffHand();
            e.setCancelled(true);
            ItemMeta meta = CustomItem.tntStick.getItemMeta();
            meta.setCustomModelData(2);
            e.getPlayer().getInventory().getItemInMainHand().setItemMeta(meta);

            world.playSound(e.getPlayer().getLocation(), Sound.ENTITY_TNT_PRIMED, 1, (float) 1.2);
            world.playSound(e.getPlayer().getLocation(), Sound.ITEM_FLINTANDSTEEL_USE, 1, (float) 1.2);
                return;
        }

        if((e.getAction()==Action.RIGHT_CLICK_AIR||
                e.getAction()==Action.RIGHT_CLICK_BLOCK)&&e.getPlayer().getInventory().getItemInMainHand().getType()==Material.SCUTE&&
                    e.getPlayer().getInventory().getItemInMainHand().getItemMeta().getCustomModelData()==2)
        {
            ItemMeta meta = CustomItem.tntStick.getItemMeta();
            meta.setCustomModelData(1);
            world.playSound(e.getPlayer().getLocation(), Sound.ENTITY_SNOWBALL_THROW, 1, 1);
            e.getPlayer().getInventory().getItemInMainHand().setItemMeta(meta);
                return;
        }
    }

Any idea what i could do?

[young knoll]

You can make it unstackable

Add a random uuid to pdc

[tribal zephyr]

What is the windowClick packet?

[chrome beacon]

depends

[wooden frost]

can it overlap?

[chrome beacon]

why do you need it

[tribal zephyr]

There are crashes with it on 1.20.1, (I think)

[chrome beacon]

Just update

[tribal zephyr]

I just wanted to know what it was for

[chrome beacon]

It's for when clicking in inventories

[tender shard]

No, then they‘d be stackable

Just add a pdc tag with name „unstackable“ and value random uuid

[wooden frost]

ok

super strange

i even changed the order in which the functions are executed (the function that requires changed custom model data comes first and the one that changes it comes second)... IT STILL RUNS WRONG WTF

@EventHandler

        }

    }

probably a stupid mistake, i tend to do those

but how

...

[smoky anchor]

please take a look at early return
or guard clause

[valid burrow]

can u use ?paste instead

cant read this

[wooden frost]

what

[valid burrow]

?paste

[undone axle]

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

[valid burrow]

put your code in there

[wooden frost]

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

ok

[valid burrow]

okay what exactly is the problem

[wooden frost]

so it runs in a wrong order

[wooden frost]

like it executes both of the ifs at the same tick

that should not happen

[valid burrow]

both of what

[wooden frost]

if statements

yet it should not be possible

[valid burrow]

why not

a code can run through 2 if statements

[wooden frost]

I dont want it to... tho

[valid burrow]

put return; at the end of your 1st statement to prevent that

[wooden frost]

i tried using return; it still did not do that

[valid burrow]

return; will make the code stop

[wooden frost]

yeah it didnt ima try again

it maybe will work

[valid burrow]

where did you put it

[wooden frost]

in the end

@EventHandler
    public static void playerInteract(PlayerInteractEvent e)
    {
        World world = Bukkit.getServer().getWorld("world");
        if((e.getAction()==Action.RIGHT_CLICK_AIR||

            return;
        }

    }

[valid burrow]

well

you want to only run the first statement or tthe second statement

so

you need to stop the code after the first statement

put it before the first if statement ends

or do else if

like this https://paste.md-5.net/eyijibalid.java

[wooden frost]

Yeah

no i copied it

still executes both

[hushed spindle]

how do you remove plugins off of spigot again? i got a couple i don't maintain any more

setting them to premium right

[shadow night]

you report them and say to delete I think

[quaint mantle]

I would do something like

@EventHandler
public static void playerInteract(PlayerInteractEvent e) {
  World world = Bukkit.getServer().getWorld("world");
  org.bukkit.event.block.Action action = e.getAction()
  Player player = e.getPlayer();

  if (!(action.equals(Action.RIGHT_CLICK_AIR) && action.equals(ACTION_RIGHT_CLICK_BLOCK))) return;
  //If the interaction is not a right click to air or block, do nothing

  ItemStack item = player.getInventory().getItemInMainHand();
  if (item == null || item.getType().equals(Material.AIR)) return;
  //If the item is null or air, do nothing
  
  Material type = item.getType();
  ItemMeta meta = item.getItemMeta();
  if (meta == null) return; //Just in case, don't really needed

  int modelData = meta.getCustomModelData();
  if (modelData == 2) {
    e.setCancelled(true);
    world.playSound(player.getLocation(), Sound.ENTITY_SNOWBALL_THROW, 1, 1);
  } else if (modelData == 1) {
    ItemStack off = player.getInventory().getItemInOffHand();
    if (off == null) return;

    Material typeOff = off.getType();
    if (type.equals(Material.SCUTE) && typeOff.equals(MaterialFLINT_AND_STEEL)) {
      player.swingOffHand();
      e.setCancelled(true);
      ItemMeta meta = CustomItem.tntStick.getItemMeta();
      meta.setCustomModelData(2);
      player.getInventory().getItemInMainHand().setItemMeta(meta);

      world.playSound(player.getLocation(), Sound.ENTITY_TNT_PRIMED, 1, (float) 1.2);
      world.playSound(player.getLocation(), Sound.ITEM_FLINTANDSTEEL_USE, 1, (float) 1.2);
    }    
  }
  //If you end up adding more, I would recommend a switch structure instead
}

[shadow night]

if you end up adding more, you should make some system to do that

[quaint mantle]

Yes, that's a better solution

[shadow night]

I have a registry system that works with namespaces stuff, so I could make that in like 2 classes

[quaint mantle]

That's way better, the code would look cleaner than that

[shadow night]

yes, probably

[proud badge]

What would be the best way to do this:
For the next 5 seconds (while the hologram is alive) I need it to be teleported to 2 blocks above the player's location, so its constantly there, even if the player moves.

Maybe something like this would work?

uh oh, server crashed

[tender shard]

yeah because you kept it stuck in the while loop

[proud badge]

what could I do to not make it stuck then?

[tender shard]

use a scheduler to teleport the entity every tick

also why are yo uchecking the command's name in the onCommand method?

[proud badge]

so I know its the right command

[tender shard]

did you register this executor to a ton of different unrelated commands, or why do you need to know that?

the proper way is to simply only register the executor to the correct command o0

[proud badge]

so... wait... you're right

[tender shard]

and then:

?scheduling

?scheduler

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[tender shard]

use runTaskTimer with a delay of 1 tick that teleports the entity every run

[quaint mantle]

Bros can do async I think

Holos are mostly IO stuff

[proud badge]

no because hologram (armour stand) is being teleported

also, how would I make the runtasktimer only run whilst !holo.isDeleted()?

[tender shard]

create a class that implements Consumer<BukktTask> and takes in the entity as constructor parameter, then once it's dead (or isDeleted or whatever) call BukkitTask#cancel()

e.g. like this

        Player player = null;
        Entity hologram = null;
        Bukkit.getScheduler().runTaskTimer(myPlugin, task -> {
            if(hologram.isDead()) {
                task.cancel();
            } else {
                hologram.teleport(player);
            }
        }, 0, 1);

or with a declared class

public class HologramTeleporter implements Consumer<BukkitTask> {

    private final Player player;
    private final Entity hologram;

    public HologramTeleporter(Player player, Entity hologram) {
        this.player = player;
        this.hologram = hologram;
    }

    @Override
    public void accept(BukkitTask task) {
        if(hologram.isDead()) {
            task.cancel();
        } else {
            hologram.teleport(player);
        }
    }
    
}

[proud badge]

ok epic thanks

[hushed spindle]

is there some app or plugin that trims a world size by removing chunks that haven't been changed by a player

[worthy yarrow]

so dynmap has this thing where if you hold compass and a sword you are invisible on the map, squaremap has none of these things, would it be possible to implement it on squaremap? If anyone has some experience with squaremap api please let me know!

[native surge]

@hushed spindle Try looking in to https://docs.pufferfish.host/plugins/trim-minecraft-world-mcaselector/

[hushed spindle]

ah sick

thanks man

[quaint mantle]

Anyone know good chart image generator libary for java?

(I want to do something with maps)

[wooden frost]

OH WAIT @valid burrow I realised what the problem was. If you have two items in (off and main)hand it uses the interaction event twice. Any way to prevent that?

[hazy parrot]

Char.Js, they have wrapper for java

[icy beacon]

Chart.js?

[hazy parrot]

Yes

[icy beacon]

Tyty

[hazy parrot]

Or smth along those lines

[icy beacon]

Also need that lol

https://github.com/mdewilde/chart/

I think it's this

[hazy parrot]

They have official one

[icy beacon]

As official as it can get, no?

[wooden frost]

thereee i fixed it. found the event has a method Gethand :)

[worthy yarrow]

Anyone have some experience with squaremap’s api? I want to implement something that dynmap has where a player holds both a Diamond sword and a compass making them invisible on squaremap

[quaint mantle]

Is that IO thing?

Or it just runs js code

[icy beacon]

I have no idea

I looked it up in 40 seconds

[hazy parrot]

Oh, cool then

[valid burrow]

arl nice

[karmic mural]

Anyone ever had an issue with BlockFertilizeEvent being cancelled but the bonemeal still being used?

Or am I targeting the incorrect event to detect and cancel bone_meal application?

[clever lantern]

how do i get the world player got into from PlayerChangedWorldEvent

[young knoll]

It's their current world

[clever lantern]

ah okay

[slate tinsel]

If I want to draw a straight line between point a and point b, which are two locations, what is the easiest thing to use? Between these points I also want to retrieve all locations.

(If it's possible to instead add velocity to change direction so it's just not a straight stretch that would be great)

[tender shard]

create a vector between A and B, normalize it, multiply it with the desired gap between locations, and then keep adding it to to Location A until you're at B

[misty current]

hello, small question about code design. I am making a proxy composed of multiple instances and I need to handle player data loading. To prevent data duplication and desyncronization, should I only allow the proxy to load data and then send it to the server where the player is connecting to through plugin messages/a socket or should I use something such as redis to cache online player data and send it to the server requesting it?

[quaint mantle]

MySql

[misty current]

and in case I use redis, how can I prevent data duplication? Is there some sort of lock to block access from a certain value until the lock is released?

[quaint mantle]

Have permissions

And unique keyword

[misty current]

I am already using mongodb for data storage, I am not asking about suggestions for data storage, i'm looking for suggestions about caching the data and sending it to where it is needed

[quaint mantle]

Dont use the socket if servers are not in one machine

[astral scroll]

when doing player.inventory.contents (in kt) if an item is empty on the inv is it air or null

[quaint mantle]

Redis for sure

[remote swallow]

normally i think we use air but theres still null in places

[astral scroll]

im getting kinda fucked with that

cause idk if its air or null

lol

[quaint mantle]

Craftbukkit ❤️

[astral scroll]

its null

but there's a 41

item?.type is 41

nvm

said nothing

[astral scroll]

can i delete a world?

like in code

[ivory sleet]

How much experience do u have with caches?

[misty current]

not much i'd say

i know what caching is, but i have never used any external program such as redis

[ivory sleet]

I mean the obvious answer is that you probably want a read through and write through code implementation

But like

There is more to it if you’re willing to go deeper

[lean pumice]

public class BetterHitbox {
    private final Entity entity;

    public BetterHitbox(Entity entity) {
        this.entity = entity;
    }

    public boolean areLookBy(Player player) {
        BoundingBox hitbox = entity.getBoundingBox();
        return player.getLocation().getDirection().isInAABB(hitbox.getMin(), hitbox.getMax());
    }
}

Return always false, because?

[misty current]

not sure what you mean with that

[lean pumice]

get if the player is looking the entity

[young knoll]

Players look vector will almost certainly not be in an entities bounding box

Unless they are very close

You need to raytrace

[misty current]

i was replying to conclube

[lean pumice]

in paper dont go, i want use it in spigot and paper

[misty current]

right now i cache player profiles in an hashmap and i pull data from mongodb

but i've figured out i probably need a better caching system to do what i described

[ivory sleet]

Alr I found it

This is a good read

https://docs.oracle.com/cd/E15357_01/coh.360/e15723/cache_rtwtwbra.htm#COHDG5177

Its not entirely up to date i believe but it gives you the basics

Assuming you’re planning on using redis

[misty current]

so what i was thinking was pulling data from mongo when a player joins the proxy, store to redis and when the player moves to a server, make the instance read from redis and parse the profile

when a player leaves a server, serialize the data and send to redis

when a player moves from a proxy to another, data is saved to the cache and then pulled again

[misty current]

lemme read that rq

[young knoll]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html#rayTraceEntities(org.bukkit.Location,org.bukkit.util.Vector,double,double,java.util.function.Predicate)

[lean pumice]

i know it

but i want use the AABB

because PaperMC is very poorly made and there aren't any useful things

[misty current]

are you suggesting i use Coherence to cache data?

never heard of it

but a read-through cache sounds like something i would need

[obsidian drift]

I'm trying to update a plugin from 1.19.2 to 1.20.4, and Registry.BIOME_REGISTRY doesn't exist anymore

WritableRegistry<Biome> registryWriteable = (WritableRegistry<Biome>) dedicatedServer.registryAccess().registryOrThrow(Registry.BIOME_REGISTRY);

Anyone know what I can use instead?

[young knoll]

?mappings

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[young knoll]

net.minecraft.core.registries.Registries

[obsidian drift]

How did u find it so quick?

[young knoll]

magics

[obsidian drift]

How tho

because u cant search up field names

[young knoll]

I just searched Registry and found RegistryKeys in yarn mappings

Which was correct

[ivory sleet]

The issue with a fully read through write through system is that you may be bound to double lock your system

[quiet ice]

Really stupid question but is there any way to express boolean return = obj instanceof clazz as a method handle? clazz can be a java.lang.Class object but other things work. Of course I could directly call Class#isInstance via a method handle but I figured that ought to be better ways around it

[chrome beacon]

obj.getClass().isAssignableFrom(clazz)

[quiet ice]

Well that is the same thing as using clazz.isInstance(obj)

might be even worse honestly

[chrome beacon]

ah right I miss read your question

[river oracle]

if you're using MethodHandles you should really know what they are returning tbh

just blind cast the result if you're wrong you aren't using the correct version of the library / code you are reflecting

[quiet ice]

Problem is that I give it an interface and call a method on it. Instead of throwing some random exception I'd rather print the exact cause of the issue. The other parts were rather easy to set up, but I wasn't able to find a neat drop-in replacement for instanceof.

[ivory sleet]

Id say isInstance is best

[quiet ice]

Basically right now I have

            if (modJar instanceof SoftwareComponent) {
                if (!(modJar instanceof DefaultAdhocSoftwareComponent)) {
                    throw new IllegalStateException("Only implementations of SoftwareComponent that are an instance of DefaultAdhocSoftwareComponent can be used as a mod jar.");
                }
                for (UsageContext usageCtx : ((DefaultAdhocSoftwareComponent) modJar).getUsages()) {
                    // ...

Problem is that gradle moved the package of DefaultAdhocSoftwareComponent, so I'd need to make use of reflection or method handles regardless in order to still keep compatibility with older gradle versions. Figured it might be neater to learn method handles.

[ivory sleet]

Remember instanceof is a bytecode instruction afterall, not sure how method handle-able that is

[fallen grove]

any ideas why this doesnt work on 1.20.4
PotionBrewer potionBrewer = this.getServer().getPotionBrewer();
getPotionBrewer() cannot be found, how am I supposed to get the brewer?

java: cannot find symbol
symbol: method getPotionBrewer()
location: interface org.bukkit.Server

[minor junco]

imagine java was fully type erased 💀

ala typescript style

[ivory sleet]

that’d be sad

[quiet ice]

I mean method handles do support other instructions like array element getters/setters and constructors

[ivory sleet]

yea fair enough, well i was just unsure regarding that

[fallen grove]

🗿

[quiet ice]

I'd even guess that method handles generate bytecode directly (if not even skipping that step) given that you can construct loops and other stuff with method handles

[river oracle]

because their is no method getPotionBrewer in Server in 1.20.4

@fallen grove and their never was afaik

I went back to 1.19.3 no such method
no such method in 1.18.2
no such method in 1.17.1

I could keep going but I feel like 2 years worth of updates is enough

[eternal night]

[dry hazel]

the jdk also uses isInstance, it's fine

[slender elbow]

the jdk can suck it

slorp slorp

[astral scroll]

cluster name is database name in mongo, right?

[fallen grove]

I was looking at this example to do something similar

https://gitlab.com/bdotsamir/hastepotion/-/blob/main/src/main/java/dev/akii/hastepotion/HastePotion.java?ref_type=heads

[quiet ice]

I suppose it's getting inlined then

[astral scroll]

no... 💀

[fallen grove]

but you are right its not under server

hhhhhmmmm

[quiet ice]

this is cmarco you are talking about

[river oracle]

sounds like a paper moment

[eternal night]

is it (it is)

[river oracle]

@eternal night does paper have such a method

[eternal night]

yea xD

[dry hazel]

something like MethodHandles.publicLookup().findVirtual(Class.class, "isInstance", MethodType.methodType(Boolean.TYPE, Object.class)).bindTo(clazz) should work fine

[fallen grove]

oh? so what does that mean?

[river oracle]

why? Is it useful in some way> seems kinda random is it like some mock registry type deal

[quiet ice]

Yeah already did so

[eternal night]

helper method iirc

[fallen grove]

paper has the potionmix class which i am also using, i just cannot figure out how to get the brewer

[eternal night]

spigot exposes theirs on Potion

[fallen grove]

i am crying

[eternal night]

if you want to use paper-api stuff anyway, you'll have to use paper-api lol

[river oracle]

^

[eternal night]

at which point, that method would exist

[river oracle]

I mean nothing wrong with it if you use Paper already too

[quiet ice]

Although I used boolean.class, but I guess it's equivalent even if it won't get inlined by javac

[fallen grove]

i am using the paper api, i am using the potionmix class

[ivory sleet]

boolean.class and Boolean.TYPE is the same thing

[fallen grove]

getPotionBrewer is a mystery though

nothing on docs

[eternal night]

then something is pulling in spigot-api

[river oracle]

if you're using paper api though you should seek help at discord.gg/papermc

[ivory sleet]

(He did actually)

[eternal night]

[river oracle]

us spigoters can't help with the mysteries of the random missing paper classes and methods

[inner mulch]

is there a reason why i should use placeholders, even thought i can insert the object directly into the string?

[eternal night]

depends ?

if you are talking about like SQL it would be a different answer than talking about printing something to console

[inner mulch]

So it depends on whether i use sql or not?

[ivory sleet]

And when it comes to placeholders it can be niece for configs or other types of configurable stuff :)

[inner mulch]

So readability?

[minor junco]

i mean it can theoretically attribute to having clearer readability, but it depends again

[ivory sleet]

^

[minor junco]

you should use placeholders only then, when a thing within your string is variable

then you can opt into using string#format

or default concatenation

or string builder

or whatever you want

[inner mulch]

Is "my string" + number + "afgfssa" bad practice ?

[eternal night]

Well if you use SQL, placeholders are needed because your inputs are escaped. If you just concat via a + in an SQL query you might expose yourself to SQL injection

for just plain text output, concatination is fine /shrug

[inner mulch]

Oh ok, so placeholders stop SQL injection in queries?

[eternal night]

well thats why you have setParameter on statements

[quaint mantle]

It happens when you passed user input

[ivory sleet]

YourSalvation, yk how bad websites have an input field, and then u can end up inputting some sql thingy and it ends up working

[quaint mantle]

Otherwise it does not matter

[inner mulch]

Yes

[ivory sleet]

Prepared statements as its called, is a way of compiling the sql statements you have, such that when u get the input data from whatever input field, we will already know what data, how much data and where it should be since we compiled the statement, thus arbitrary data becomes impossible to input. I think pHp had a tragic history w this type of vulnerability.

[quaint mantle]

Quick question:
I have a function which returns a CompleteableFuture<Void> and now I have a different function which calls the prior function X amount of times. How would I check that everything was completed?
Do I really make a collection of the futures and everytime one completes check every other if they are complete or not?

[quaint mantle]

await?

Do get() or join()

[zealous osprey]

But if I #get on all of them, won't it only wait for one, then the other, then the other, etc.?

can't you use CompletableFuture.allOf

[tidal kettle]

hello i try to make a square of particule, i use this code but i don't work can you help me?

like the particule go everywhere

[quaint mantle]

Locations are mutable

[tidal kettle]

yes and ? 😅

[quaint mantle]

try ploc.clone().add

[tidal kettle]

just like this it work...

so simple...

thank you...

[quaint mantle]

No problem

Locations are mutable, so everytime you use .add, it changes the location

[tidal kettle]

also when i .add a numbre <1 the particule spawn on me

any idea why?

[young knoll]

You should cast the 2 to a float

Otherwise it'll do integer division

[tidal kettle]

oo i see

[young knoll]

You can just do 2f to cast it

[sterile token]

Something is wrong with my output debugs from my command api

21:13:35 INFO: argument(faction.points.*)= false

Im not sure why i get the debug message 2 times

For debugging im running the /faction points info command and getting the output on top

[rotund ravine]

?nocode

[undone axle]

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

[sterile token]

Oh sorry the link wasnt sent it, my bad

[sterile token]

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

[rotund ravine]

argument.execute

[sterile token]

what do you mean?

I must apply recursion, because a ParentCommand command can be parent of another command

Like Tree strcutures works

• faction => ParentCommand
• list
• points => ParentCommand
  • info

[clever lantern]

someone knows why this doesnt work in nether (didnt test in overworld)

                lodestone.getBlock().setType(Material.LODESTONE);

                CompassMeta meta = (CompassMeta) itemStack.getItemMeta();
                meta.setLodestone(lodestone);
                meta.setLodestoneTracked(true);
                itemStack.setItemMeta(meta);```

compass is still spinning

[rotund ravine]

So you get two outputs

[sterile token]

yeah exactly when executing the info command from points. I get 2 differents outputs

One of them is correct, which the second one

argument(faction.points.info)=true

[rotund ravine]

.

[sterile token]

okay, but can you detail more please

im not really understanding

I dont wanna sound as troll, but i dont catch where you trying to go with the argument.execute()

cuz, argument execute calls the execute method from the command class itself?

🤔

[rotund ravine]

Execute debugs

U call it more than once

U get more debug statements

[sterile token]

the argument.execute() is calling that execute method

[rotund ravine]

I guess it is not

[lost matrix]

Try setting setLodestoneTracked(boolean tracked)

[sterile token]

im struggling because yesterday after removing the debug message to add the permission check started to happen this issue i posted. Because before touching the code, the debug was giving just one output and with the correct info

[sterile token]

remember i nee to apply recursion, that why im calling the argument#execute(). Because ParentCommand can be parent of another ParentCommand, just like how a LinkedList works tho

[clever lantern]

yeah there is a line setting that to true

[sterile token]

@rotund ravine sorry for tagging but this is not normal

i just removed all debug messages, created just argument.bla() debug and is okay

Can I create a ServerSocket if the port is already used?

[ivory sleet]

no, i mean it’s still possible to create a server socket and not have it binded

But like, if a port is used, then na

[grim hound]

But like listen to the connections?

[ivory sleet]

you mean when the clients connect?

yeah multiple clients can connect to the same server socket

[grim hound]

Yeah but like

When I tried doing it with netty instead

I got the PortBindedException or smthg

[ivory sleet]

What did you try?

[grim hound]

try {
    ServerBootstrap serverBootstrap = new ServerBootstrap();
    serverBootstrap.group(bossGroup, workerGroup)

            .childHandler(new Interceptor());

} catch (InterruptedException e) {
    throw new AlixException(e);
} finally {
    bossGroup.shutdownGracefully();
    workerGroup.shutdownGracefully();
}

Made by chat gpt

Or if this is valid, where can I find the ServerBootstrap variable

[tender shard]

seems like you're trying to listen on an already used port

[grim hound]

To add my childHandler

[grim hound]

Figured

[sullen marlin]

What are you trying to do

[grim hound]

Seems it's probably used by the server

[grim hound]

AntiBot

Fast connection refuse

FireWall in other words

[sullen marlin]

Why not, y know, a firewall then?

[grim hound]

For now I'm only using APIs for that

[grim hound]

Is there a way I could add an ip to the server's firewall in java?

[sullen marlin]

Run the relevant command

[grim hound]

Hmm

And will it work always?

Like if the command is correct

[sullen marlin]

What do you mean

[grim hound]

Would every system accept the command?

Does every os have a firewall

Interaction command?

[sullen marlin]

I mean probably?

[grim hound]

Makes sense

[sullen marlin]

Make the command configurable

[grim hound]

Will do 👍

[tender shard]

i doubt that the server has (or should have) root perms 🥲

[grim hound]

Oh yeah

md5, can we execute root commands?

[tender shard]

only if the server has root ofc

[grim hound]

But then

Uhh

[tender shard]

what one could do is to allow password-less sudo for only certain commands, e.g. iptables, with /etc/sudoers

[grim hound]

Why would someone restrict it and someone not?

[tender shard]

ofc that would never work for shared hosters etc though

[slate tinsel]

Hi, when I retrieve the projectile's location in the hit event, it is sometimes up to 3 blocks wrong, i.e. not all the way, mainly this occurs when the projectile travels very fast, for example from a crossbow. Anyone know how I can solve this?

[warm mica]

I guess just listening to AsyncPlayerPreLoginEvent is probably fine for whatever you are trying to do

[grim hound]

Hellll naaawh

That is way after everything

It'd be far more laggy if I were to do that

Or unoptimized, I should say

It'd a shame for an antibot to have it's main firewall be that

[warm mica]

Uh, I don't think it matters. It's enough for a bot that joins every now and then. You are not trying to block a DDoS attack, which you couldn't do anyways on that level

[spare mason]

why if i unload and load an nms entity it is no longer custom and turns into a normal nms entity of it's original type

[warm mica]

Because neither vanilla minecraft nor bukkit were designed for that. It reconstructs the instance using the original class when the entity gets loaded again

[wet breach]

Its not going to make a difference if the connection is halted at the system level or not as the connection reached the system anyways. If you do it at prelogin the server hasnt processed much and you can suspend connections here without causing issues to the server. If you are worried about lag you need to have a box that is further upstream that monitors connections

[grim hound]

That is pretty ignorant

[grim hound]

Same here

[hazy parrot]

I mean, they are both correct

[wet breach]

Its not ignorant just a fact that all you are doing is just changing where in the system the connection is halted. If you add more and more rules to the system firewall eventually you will overwhelm the system which is no different if the mc server is doing it. It is too late to really do much about a connection that has reached a system as it will consume resources regardless. If your goal is to avoid this you need to stop the connection further upstream this is why you can rent firewall boxes

[warm mica]

"on that level" I don't mean that in an offensive matter (if that's what you have interpreted), but rather that you won't be able to stop a DDoS attack on the application level

Thoughts on this? I'm trying to improve minecraft's biomes by adding more color variation to trees. Does the sky color seem good?

Color and sky variation is done through my biome editing system

[sullen marlin]

Never seen a sky that colour irl

[young knoll]

Australia only has gray/red skies because of all the wildfires

Imean what

[opaque scarab]

Yeah working on the sky colors. I do think vanilla’s sky is too blue though

[young knoll]

Is this modifying existing biomes

Or replacing them with custom ones

[velvet hawk]

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

i only extend javaplugin in one class idk what im doing tho

[young knoll]

Make sure you never try and create a new instance of your main class

[velvet hawk]

im pretty sure i dont do that anywhere

What does Techniques.java look like

?paste

[undone axle]

[velvet hawk]

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

It replaces them with custom ones, while containing the default data such as mob spawning

[young knoll]

Hmm that looks fine

What is your plugin.yml

[young knoll]

At worldgen or via packets?

[velvet hawk]

quite simple, i didnt really know how to set it up properly, do I have to like add loadbefore or softdepend idk anything about plugin.yml configuration

[opaque scarab]

On startup, a list of all default biomes within the world are gathered. It iterates through the list creating new registries of the same biome. These new copies have the same path, but a different namespace (specified by the plugin). When a chunk is loaded, it’s checked if the chunk contains the necessary alterations. If it does not, the biome is changed in specific places with the copy, according to a simplex octave generator.

I don’t quite understand simplex octave generators, but I got it working

[young knoll]

So it’s done at worldgen, neat

[young knoll]

Looks alright, you should probably have depend: [worldedit] if you depend on it

[velvet hawk]

this seems to have fixed it

still giving errors but thats my code's problem

Same basic stuff, but just different code

If that made sense LOL

Also releasing a tutorial for custom blocks with GeyserMC

I’ll release the custom biome tutorial on the spigot forums, and MAYBE YouTube

For geyser, IDK

Somewhere. People need to know stuff about geyser because their documentation is completely useless

Sure! It’s Cyrei

Same name

[tender shard]

blue name = verified = same discord and spigot name 😛

it was possible to trick the bot but this got fixed meanwhile i think

[opaque scarab]

You could have discord associated with a past account?

[tender shard]

well ok but in 99% of cases, it should be the same name lol

[grim hound]

What kind of logic is that?

[opaque scarab]

Yes, you can do it through datapacks. I use custom biomes for seasons though (a plugin I’m developing). Adding custom biomes through plugins gives me more control for this. Plus, you don’t need a datapack and a plugin

Yeah great, I can't block 10 million connections per second so I should assume it's 1 bot per 5 seconds and block at most that

Logical fallacy

[tender shard]

CraftItemStack#asCraftMirror or sth similar

[opaque scarab]

I’m not very familiar with data packs, but to my knowledge, biomes must be hardcoded into the pack. My way allows me to make changes on every initialization

[hot reef]

yes and sadly its the only stuff i got, and i tried doing craftitemstack but idk how to get it into my program

[opaque scarab]

Now I’m curious if that would work… I probably won’t try it, but

[tender shard]

one of those, preferrably asCraftMirror @hot reef

Oh I did nice

[hot reef]

do i just copy that and put it in and use it?

I'm using the asNMSCopy

[tender shard]

no, you're usually supposed to understand what it does, then you know what to copy/paste, if anything

[grim hound]

And you want asCraftMirror

[hot reef]

yes

[grim hound]

So replace that in the code

Also, I input ItemStack as the argument

And you want to do the reverse yeah?

[tender shard]

btw shouldnt you cache all those reflection stuff?

[grim hound]

Nms to bukkit

[hot reef]

my brain hurts

but i think i follow

[grim hound]

Do you not see the 50 variables?

[tender shard]

I'd just add craftbukkit as dependency and call CraftItemStack.asNmsCopy directly

        } else {
            banEntry.setExpiration(banTime);
        }
    }

How do I do a tempban thingy?

If change it to this

public static void tempBanPlayer(Player p, int dungeonTime, String reason) {
        long durationInMillis = (long) dungeonTime * 60 * 60 * 1000;
        Date banTime = new Date(System.currentTimeMillis() + durationInMillis);
    
        BanList banList = Bukkit.getBanList(BanList.Type.NAME);
    
        // Note: Use the player's name for ban entry
        BanEntry banEntry = banList.getBanEntry(p.getName());
    
        if (banEntry == null) {
            // The player is not already banned
            banList.addBan(p.getName(), reason, banTime, null);
        } else {
            // The player is already banned, update the expiration time
            banEntry.setExpiration(banTime);
        }

        PlayerProfile profile = (p.getProfile());
        BanEntry<PlayerProfile> banEntry = banList.getBanEntry(profile);  

The method getProfile() is undefined for the type Player

well damn

getPlayerProfile()

And BanList<PlayerProfile>

[vernal oasis]

I am aware this is the Spigot server

[dry hazel]

you are using paper API

[vernal oasis]

ah, depencencies...

Thanks md_5

It would appear that the project was created w/ paper instead of bukkit

[shadow night]

Md 5 has sent more whereami's this hour than I have in my life

[vernal oasis]

Yeah I was confused why the bukkit api wasn't working on that...

That makes quite a bit more sense lol

How to set npc skin using protocollib?

i use this one
profile.getProperties().get("textures").forEach(property -> profile.getProperties().put("textures", new WrappedSignedProperty("textures", property.getValue(), property.getSignature())));

but it didn't show anything

[inner mulch]

Hello im trying to spawn 36 different particles, they are supposed to be colored like a rainbow in order, i dont want to hardcode the color, therefore, does somebody know a reliable way that i could calculate the colors and get them from rgb

[echo basalt]

well the rainbow and the rgb spectrum are two different things

[inner mulch]

okay

[echo basalt]

I'd recommend hardcoding these 7 values and interpolating between them

[inner mulch]

So hardcoding would be the way?

[echo basalt]

you hardcode the rainbow

and you generate all the points between them

[inner mulch]

okay

[wet breach]

you don't necessarily need to hardcode

I recommend sticking with RGB because you can use bitshifting

and with just a shift of a bit or two you can essentially get any color and value you want

[inner mulch]

bit shifting sounds bad

[wet breach]

its not

I have a project that demonstrates it with rgb

basically it compresses 32bit colors to 8bit colors

[inner mulch]

I meant to say it sounds hard

[wet breach]

https://github.com/frostalf-games/ConsoleColors/blob/master/src/main/java/net/frostalf/consolecolors/ColorConvert.java

[inner mulch]

Thanks i will look into that

[echo basalt]

Well yeah you don't need to hardcode you can just have it be configurable

you still need to know the 7 colors of the rainbow as there's like no mathemathical expression to gen it

[terse ore]

If I want to make so certain set of players cant break blocks placed by another set of players, is there a better idea to store the blocks placed in a list and check if that block was placed by another player?

[wet breach]

actually there is, you only need to know red, blue and green

[echo basalt]

is it sumn cursed

[wet breach]

and even then those don't need to necessarily be hardcoded either since you know the limit is 255

[echo basalt]

I'm talking about the starting colors

interpolation is separate

that can be algorithmic

Like there's no obvious pattern for the rainbow

[wet breach]

there doesn't need to be one

as long as you know the ranges for the colors you want

the order is arbitrary really

[echo basalt]

it's not linear..

whatever

[wet breach]

not sure what you mean linear

255,0,0 is red, 255,255,0 is yellow

0,255,0 is green and so forth

127,255,0 is green if I remember right

er not green

0,0,255 is blue lol

127,255,0 is lime green

just because something isn't linear doesn't mean it has to be hardcoded

I will admit non-linear things are not as intuitive to see it though

[echo basalt]

homie I know how colors work

I just don't know how you expect me to create a rainbow algorithmically without having at least 7 colors to start with

public List<Color> createRainbow(int listSize) {

}

[terse ore]

thanks, did not remeber this existed

[wet breach]

you only need 3 colors

and as I said you already know the limits of each

[echo basalt]

That's the rgb spectrum not the rainbow

[wet breach]

you only need the limits of those 3 colors

255,0,0

255,255,0

0,255,0

[lost matrix]

Interpolating in RGB works very poorly

[echo basalt]

frosty talking about the rgb spectrum not the damn rainbow wtf

[wet breach]

I already told you about the raindbow

the rainbow isn't some mystical colors

its a combination of the primary colors

something you learn in school

also so happens to be something easy to replicate with just rgb

[grim hound]

is it possible to have like an already existing Spigot server

but link a sub-server to it?

[grim hound]

with a plugin

[lost matrix]

What does this "link" do?

[grim hound]

like he tries to join this

[grim hound]

gets thrown here

and back at one point

[lost matrix]

That just sounds like a perfect task for a proxy

BungeeCord, Waterfall, Velocity

[grim hound]

would it be possible to do on a Spigot server?

[knotty aspen]

that is the exact task a proxy is made for

so just use that. they are all very lightweight

[grim hound]

then how could I boot up a server

with a plugin?

[lost matrix]

Hmm. That would be extremely hard to do because you would have to use the spigot server as a proxy.

[grim hound]

on like a proxy

creating a dummy server with a plugin

with my own server engine

[lost matrix]

Start a jvm and use a server jar as target. Just like you would in your terminal.

[grim hound]

can't I use the currently existing JVM?

or do proxies have a vm for each server?

[lost matrix]

How do you expect two applications share their stack?

[grim hound]

hmm

I see

[lost matrix]

Proxies dont own any servers. They just reroute packets from client A to server X,Y or Z

[lost matrix]

You mean emulate a server using a plugin on your proxy?

[grim hound]

yep

[ivory sleet]

Its really nice to just isolate each backend server into its own jvm, and then having your proxy on a separate jvm, in practice everything could run on the same jvm, but that sounds like a duct tape hassle

[lost matrix]

Sure, that can be done. You just need to implement the protocol.
But be prepared to write a ton of code. Also proxies are really not meant to have any functionality besides
routing packets.

Maybe explain what you are trying to do. I smell an xy problem.

[wet breach]

technically yes

should you? probably not

[grim hound]

create a server on like BungeeCord/Velocity

and connect the player to it

[wet breach]

you want dynamic servers?

[grim hound]

and have it create from my own server engine jar

[grim hound]

just 1

unchangeable once created

[wet breach]

I am not understanding what it is you want then

[grim hound]

.

[grim hound]

.

[grim hound]

.

[wet breach]

ok, but it still doesn't make sense

or is not very clear in what you are trying to achieve

[grim hound]

Create it

with a plugin

that is placed on the proxy server

and is of my own creation

so I code this plugin

[lost matrix]

How would you run two applications on one jvm? I dont think thats really possible without having an additional layer.

[grim hound]

I'll make a vm

[wet breach]

It is possible to do, just not from a plugin because it is too low in the program process

[grim hound]

can I start another vm from java?

[wet breach]

you need to use a Java Agent which handles processes in the JVM

[wet breach]

yes

[ivory sleet]

No i mean like, assuming you own the software, its possible to invoke the server socket for both backend servers and the proxy server on the same jvm

[grim hound]

is that like a library or something connecting many jvms?

[ivory sleet]

but you probably shouldnt

[wet breach]

No, its part of the JDK

its designed to be a wrapper around JVM processes

[lost matrix]

And who initializes this agent? You would need an additional application which was written to handle several sub-apps.

[wet breach]

basically you would create a wrapper client which makes use of Java Agent, it can then launch Java processes inside of it

or launch JVM's outside of it

should you do this or is it wise? Not really, the only nice thing of a Java wrapper client is that it can do some utility things for you that make it easy

like letting you know if a server died or something and rebooting it back up

etc

[grim hound]

I want it to be as efficient as possible

[lost matrix]

Are you trying to dynamically start/stop spigot servers, based on demand?

[wet breach]

ok that is fine, but your idea isn't efficient or optimal

[grim hound]

no

proxy starts up

I look for my dummy server

if not present I put the jar file

and start it

and send players to it

just 1

[wet breach]

They want the ability to start up more servers without creating more JVM processes, basically have a single JVM process where everything is in that

[lost matrix]

Ok. But why?

[grim hound]

No.

JUST 1

1 SERVER

a dummy server

[lost matrix]

Then take 2 steps back and explain what your goal is.

We are still doing xy

[grim hound]

Okay let me be clear:

a Velocity server starts up

I want to create a dummy server

[wet breach]

oh you want the proxy server to also be the hub server?

[grim hound]

where I'd send players as the primary one

[grim hound]

not necessarily

[wet breach]

yes this is doable, in fact a world doesn't even need to actually load for a player to connect to it just fyi

[grim hound]

tbf it's for my antibot

[wet breach]

so what you are wanting is completely doable on a proxy

[grim hound]

I plan to develop a server engine

to have it as efficent as possible

[wet breach]

ok, well I don't know what inefficiency you are experiencing

[grim hound]

but I still don't know how I could start a server from within a plugin

[wet breach]

you saying efficient as possible is just arbitrary at this point

[grim hound]

I haven't done anything yet, but I'd like to start from the right point

so that I don't have to recode it later on

[grim hound]

tis

[lost matrix]

Is this public or for private use?

[wet breach]

well you keep explaining dynamic servers, but you keep saying no you don't want dynamic servers despite what you are describing

[grim hound]

public

[grim hound]

like I said, I want only 1 server

and it's unchanging

[wet breach]

yes that is hubs for you

they don't typically change

[grim hound]

no, the server will have it's own hub

[wet breach]

so 2 servers now

[grim hound]

my dummy server will just be for verification

[lost matrix]

Does it need to be a spigot server, or just a "place where a client can connect to"

[grim hound]

2nd

I'm planning on creating my own server engine

[wet breach]

ok what kind of verification is needed?

[grim hound]

so I have the jar, how could I create a dummy server the player could connect to

[wet breach]

because I may have an easy solution which requires nothing but a hub

[lost matrix]

There is no need for a server engine.
You can just emulate the protocol and send a few packets.

[grim hound]

I'll decide on that, but a visual one for sure

[wet breach]

ok that is it?

[grim hound]

yep

[wet breach]

use demoscreen then

[grim hound]

just like netty communication

[wet breach]

when they connect to the hub, give them the demoscreen

you can do all kinds of things with that

[grim hound]

Can you help me with my problem tho?

[grim hound]

For the past 15 minutes I've asking for this

on a proxy

[wet breach]

you can even do visual verification with demoscreen too since there is buttons for the screen 🙂

[grim hound]

I'll decide on that

for now PLEASE

ANSWER THE QUESTION

[wet breach]

then I decide I will go back to my game

since I get to decide that

have fun

[grim hound]

mhm

[grim hound]

oo

[wet breach]

just fyi, you are talking with the few people who are actually highly experienced with dynamic servers

but what you want doesn't need any protocol manipulation or even a second server

can all be done on the hub

[grim hound]

but I want to minimize or remove calculations made by the server

[echo basalt]

that's still the rgb spectrum, just 8 points evenly spread out

[lost matrix]

What does "server" refer to here?

[grim hound]

Go back to your game

[grim hound]

the server the player is currently on

if I had my own server engine I could ensure that

[echo basalt]

Well

[grim hound]

thus why I want to create the server

[echo basalt]

You basically want a cloud system

and that's core java and not plugin related

[lost matrix]

I thought he said no to that...

[wet breach]

which is what makes it all the more confusing lol

[grim hound]

I really dunno what that is

[echo basalt]

You need a "core" service that receives a server creation request and sends it to one of its "workers" (one per machine) that make sure the image is up to date and starts a server out of that

[ivory sleet]

What has he said yes to?

[grim hound]

yeah

[echo basalt]

You want the server allocation part

Well that's a cloud system

If you want an already existing one there's TimoCloud

[wet breach]

which in a nutshell is a dynamic servers setup

[echo basalt]

I don't understand CloudNet enough to recommend it

I'm just making my own because I can

[wet breach]

which is what was asked quite a few times

[lost matrix]

Wait. Initially the player is on no server. And my interpretation was that you wanted a
minimal server implementation without any functionality (no world, no entities, no other players, no chunks etc)
with just a limbo. And that could be done on a separate thread, started by the proxy, simply sending a few packets.

[ivory sleet]

The loadbalancer is basically velocity/bungee

[echo basalt]

The loadbalancer can run on top of the proxies so that no individual proxy gets overloaded

[grim hound]

that'd be correct

The player on login is redirected to an empty server

which my plugin would create

[echo basalt]

So we're talking 2 separate things

[ivory sleet]

Does Shadow really need a hierarchical proxy topology?

[wet breach]

probably not

[lost matrix]

Alright, then just look at the protocol and send a few packets.

[wet breach]

they just want a verification system for their anti-bot thing

[echo basalt]

Instead of having a "plugin create a server" you'd have a matchmaking service and a server management system working together

[wet breach]

and they seem to be going on the path of over engineering right now

[echo basalt]

but we're probably not talking about cloud anymore

[grim hound]

Bruh.

[ivory sleet]

Yea

[echo basalt]

we've reached the holy lands of ?xy

?xy

[undone axle]

http://xyproblem.info/

[echo basalt]

bot pls

[grim hound]

?

I've explained many times what I want to achieve

[echo basalt]

You've thought so hard of an anti-bot solution you've crossed the realms of cloud server management

:)

Maybe what you want to achieve isn't the right solution to your problem

[wet breach]

literally they could make use of demoscreen XD

it is in the API

[grim hound]

Ignorant.

[wet breach]

so far everything they asked in what it needs to do

demoscreen provides

and this can all be done on the hub

[echo basalt]

welp I'm done here

[wet breach]

which is just 1 server and no other server spooled up

[echo basalt]

omw to spend my last 20$ at the barbershop

cya nerds

[wet breach]

cya later

get a cool haircut

[grim hound]

okay

then show me how you'd do it

[echo basalt]

imma do my beard and trim the sides n stuff

mostly maintenance so I don't look like a hobo

[wet breach]

ah

[echo basalt]

gotta pass by my school in a couple hrs to sort out some degree stuff

[grim hound]

I get that the people here only act nice and in reality are douchebags

[wet breach]

I am not entitled to be nice to anyone

yeah really depends what kind of bot problem they are trying to solve

[ivory sleet]

Without escalating rudeness, I thought smile gave you a really niece solution

[wet breach]

yeah smiles solution is nice too

if you don't want to make use of the DemoScreen stuff

after looking

it seems the API is a bit lacking on the DemoScreen area though

[ivory sleet]

Obviously the fact that illusion deployed a huge skull emoji sticker is a bit rude, but don’t think any of us meant any harm or rudeness initially

[lost matrix]

I think the Game Event packet handles that. Never used it so far.

[wet breach]

I have seen it used, and there is a lot that can be done with it

it takes the player to like a separate area where you can give tutorials etc if you wanted

its really cool

[lost matrix]

Lecture continues see ya guys

[wet breach]

cya later

[echo basalt]

That was my answer to calling frosty an ignorant

But ye I'm ticked off today

Need my 2 minutes of sleep

[tender shard]

2 minutes are over!

wake up

[wraith dragon]

guys any way to change the blast resistance of a block?

ik its with nms but so far I cant figure it out

[upper hazel]

?paste

[undone axle]

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

[upper hazel]

https://paste.md-5.net/ecerazeyil.cs - why custom craft not adding ? i not find error but crafts not exists. How check this

[wet breach]

the easiest way, is to track the resistance yourself

[upper hazel]

craft registred but not worked

[wet breach]

you don't really need to modify it, just have a list of blocks you want the resistance changed, make use of the events

[echo basalt]

I'm lined up with 1$ to spare

Every time I hit the barber the guy charges me a different price

[wet breach]

mood pricing

[echo basalt]

It's always 17-18$

[rotund ravine]

Same

[wet breach]

if they like you or in good mood, you get $1 discount 🙂

otherwise its full price all the way

[wraith dragon]

how do I track it?

[wet breach]

basically you would make a configuration that has a list of blocks that you want resistance changed to, and their values you want it to be

then its a matter of listening for events and detecting the blocks, if the resistance is to be greater, you just don't let it get destroyed if it should be less then you let it get destroyed

etc

[tender shard]

ItemStack toString() returns the same as /data get entity… SelectedItem right?

Including NBT tags etc?

[echo basalt]

I believe so yeah

[tender shard]

That‘d be great

Then i can tell people to just blacklist items by regexing toString

is there any simpler way to catch exceptions in the lambda thingy? It looks so ugly compared to the rest lol

        this.toStringRegex = config.getStringList(name + ".toStringRegex").stream().map(entry -> {
            try {
                return Pattern.compile(entry);
            } catch (PatternSyntaxException exception) {
                main.getLogger().warning("Invalid regex in blacklist entry \"" + name + "\": " + entry);
                return null;
            }
        }).filter(Objects::nonNull).collect(Collectors.toList());;
        if( main.debug) main.debug("- toStringRegex: " + toStringRegex.stream().map(Pattern::toString).collect(Collectors.joining(System.lineSeparator())));

[green plaza]

this.toStringRegex = config.getStringList(name + ".toStringRegex").stream()
        .map(this::compilePattern)
        .filter(Objects::nonNull)
        .collect(Collectors.toList());

if (main.debug) {
    main.debug("- toStringRegex: " + toStringRegex.stream().map(Pattern::toString).collect(Collectors.joining(System.lineSeparator())));
}

// ...

private Pattern compilePattern(String entry) {
    try {
        return Pattern.compile(entry);
    } catch (PatternSyntaxException exception) {
        main.getLogger().warning("Invalid regex in blacklist entry \"" + name + "\": " + entry);
        return null;
    }
}

[terse ore]

Is it possible to modify the daytime and nightime times?

so daytime is x minutes long and night is y minutes long

[ivory sleet]

Yeah that’s possible

There is an event you probably could use to reset the day time every so often making it feel longer

[terse ore]

hmm https://github.com/foncused/LongerDays/blob/master/src/main/java/me/foncused/longerdays/runnable/Runnable.java

[tender shard]

yeah lol why didnt ithink of that

[terse ore]

interesting

[ivory sleet]

alex I also believe there exists some utility thing in guava to wrap around any functional interface with a sneaky throw

maybe it was apache commons, idr but yea

[tender shard]

I'm trying to blacklist items by regular expressions, which works fine. I also added a command to automatically print out the regular expression to match exactly the item the player is holding, however admins need to throw this into a yaml, and hence I have to correctly escape it. The regular expression might look like this:

^\QItemStack{WRITTEN_BOOK x 1, BOOK_SIGNED_META:{meta-type=BOOK_SIGNED, title="Quoted" Title, author=mfnalex, pages=["\"this book contains double quotes\" and 'single quotes'"]}}\E$

Obviously it would need to be quoted to be store din a YAML. I could ofc just create a YamlConfiguration, use set("dummy", myRegex) and use saveToString(), then substring the "dummy: " part, but I wonder if there's a better way to get a correctly escaped version of this string

[tender shard]

but I also need to print the proper warning

[ivory sleet]

Myea in that case

Yes

Pattern does have a literal regex static factory method

Pattern qoute()

But I think you can otherwise construct a normal regex instance and just pass the Pattern.LITERAL flag also :)

[upper hazel]

how to display item crafts in inventory like mods (visual)

when you click and this opened in inv

[tender shard]

that only quotes the regex stuff as mentioned above (wraps it into \Q and \E) but doesn't allow me to throw it into yaml

It needs e.g. to also escape all quotes inside, all \ chars, etc

[ivory sleet]

oh

[tender shard]

i'll be back in an hour, if someone knows a solution, ping me pls :3

[ivory sleet]

Yeah I think you just mentioned the solution yourself

[hushed spindle]

im getting the following error

java.lang.NoSuchMethodError: 'org.bukkit.generator.structure.Structure org.bukkit.craftbukkit.v1_20_R3.generator.structure.CraftStructure.minecraftToBukkit(net.minecraft.world.level.levelgen.structure.Structure, net.minecraft.core.IRegistryCustom)'

but within the IDE there's no complaints about such a method not existing on 1_20_R3

how would i go about resolving that

[river oracle]

Sounds like your server isn't up to date

I'd just run buildtools for 1.20.4 and try again

[quiet ice]

(why are there even two structure classes anyways?)

[hushed spindle]

i think i got it

seems like this part of the api gets changed rather frequently

[river oracle]

Who knows

Maybe legacy stuff

[quiet ice]

Heck, there are even two structure packages

[river oracle]

Becuase nothing is ever fully removed it seems like you end up with weird artifacts

[hushed spindle]

its spaghettin' time

[quiet ice]

Well good thing is that with the release of Java 26 or so we will see the end of Java 8 - though you'd still be able to run these plugins for god knows how long

[young knoll]

One represents a structure in minecraft

Like a mineshaft or stronghold

The other is about structures you save/load with structure blocks

[quiet ice]

aren't they practically identical?

[young knoll]

kinda

The first one can't be modified or anything

But the second one can

[wet breach]

the only issue you will run into is people might notice the slight reset of the time if they are paying attention to the moon or sun
