[ivory sleet]

which replaces the value if and only if an existing value matches the “oldVal”

that can be used if u want to do stuff atomically supposing the map is one of those concurrent ones

and the atomic objects I prob dont even need to go through

[silver robin]

So I'm assuming these are javadocs, and only spigot and bukkit have them
In intellij i have two projects set up, one for 1.16.5 and one for 1.20.4, and here are the differences when I view bukkit's LivingEntity interface:

I want to see javadoc instead of decompiled code in 1.20.4, but I'm not able to figure out where's the setting for that (is it in maven or intellij or something else), could anyone help me?

[inner mulch]

I currently have a normal map in a liveobject, i will look into these methods

[smoky anchor]

Have you tried clicking the "Download Sources" button ?

[silver robin]

...

I want to add that there is a sources jar in my folder ~\.m2\repository\org\spigotmc\spigot-api\1.16.5-R0.1-SNAPSHOT, but there isn't one for 1.20.4, it only contains snapshot.jar and snapshot-shaded.jar

[tender shard]

BuildTools should have an option to install sources

[silver robin]

I fixed the problem by enabling these options in BuildTools jar, the sources jar was generated

[silver robin]

That's it, thank you

[charred blaze]

how do i set keepinventory for only one player?

[inner mulch]

Listen for their death save the inv and then give it to them when they respawn

[charred blaze]

how do u save their inv

what is proper way to do this

[inner mulch]

Do you know java

[charred blaze]

what if they leave or something

[charred blaze]

yes

[inner mulch]

Then use ur knowledge, i showed you the way spoonfeeding isnt good

[charred blaze]

i havent meant i need code

[inner mulch]

?

[charred blaze]

yea i can store his items in hashmap or something

but

what if he is dead BECAUSE he left

can you give items to offline people? no

[inner mulch]

Yes you can

[charred blaze]

you can?

[inner mulch]

With a custom inv System, by saving the inv in a DB and changing it

[charred blaze]

how

changing it when

whenever player joins?

[remote swallow]

prob on login

[charred blaze]

does giving items to player work when they have respawn screen and havent been respawned?

[inner mulch]

?tryandsee

[undone axle]

https://tryitands.ee/

[charred blaze]

?trying takes more time than asking

[inner mulch]

If you are concerned just enable to gamerule for insta respawn with no death screen

[charred blaze]

oh PlayerDeathEvent actually has .setkeepinventory

[charred blaze]

how do i make this disappear?

i clicked something on keyboard accidentally and it appeared

[lost matrix]

What are we looking at?

[charred blaze]

i dont know myself

otherwise i would have googled it

[tall dragon]

click on greeneddev

in ur text

[charred blaze]

and?

[young knoll]

looks like git blame?

[tall dragon]

it goes away

[charred blaze]

no it opened this

[lost matrix]

[tall dragon]

did u click this?

[lost matrix]

^

[charred blaze]

oh that one

[tall dragon]

yes that one

[charred blaze]

yea it works

[lost matrix]

This looks like git blame to me as well

[charred blaze]

thanks

[tall dragon]

thats cuz it is

;d

[charred blaze]

git "blame"?

[young knoll]

It tells you who to blame for each line

[tall dragon]

u can see whoever to blame for that piece of work

[charred blaze]

is that a thing

lol

[young knoll]

When something inevitably breaks

[tall dragon]

u know who to fire

super convenient!

[charred blaze]

how do i check for errors after changing something in other classes rather than clicking on each of them?

[tall dragon]

compile untill it works 😂

[charred blaze]

lol

[worldly ingot]

In fairness, I’ve had instances where I’ve named a boolean parameter something similar lol

I avoid it but it happens sometimes

[inner mulch]

why is it bad tho isnt that what a boolean is for?

enabled or disabled?

[worldly ingot]

It is, it’s just that people tend to use more relevant or descriptive names

Either “elytraAllowed” or “state”

[inner mulch]

okay

[river oracle]

Or Like isThisVariavleTrueOrFalseINeedToKnowCuzItsTheElyrtaToggle

[inner mulch]

@river oracle ocp

[worldly ingot]

Honestly not a huge deal though lol. It’s a parameter name. Worst case it shows up in parameter descriptions via Javadocs or your IDE via code mining

[slender elbow]

big disagree

[worldly ingot]

I disagree with ur face

[inner mulch]

choco when will the foraging update release?

[slender elbow]

wow

okay

[worldly ingot]

:((

The real way to do it

[river oracle]

I just name my variables var1 var2 var3 etc

It really cuts down the compile time

[inner mulch]

...

[icy beacon]

I don't name my variables because I don't have variables, they violate the idea of OCP

[tall dragon]

i ussually just use _, __, ___

really helps with readability!

[quaint mantle]

whats the size of Bukkit Maps?

i used 128x128 but thats gives OutoufBoundsException

[lost matrix]

Minecraft maps have a resolution of 128x128

[quaint mantle]

uh

[native ruin]

Usually it's 128 (0-127) so I have no idea

[quaint mantle]

    at sun.awt.image.IntegerInterleavedRaster.setDataElements(IntegerInterleavedRaster.java:297) ~[?:?]
    at java.awt.image.BufferedImage.setRGB(BufferedImage.java:1016) ~[?:?]
    at io.github.unjoinable.whosthatpixelmon.MapCommand.onCommand```

oh 0-127

xD i used 1-128

i sometimes forget things start with 0 in this game

[native ruin]

It's everywere

[quaint mantle]

1 question

when u use bukkit renderer , does it execute for every player that loads the same map or is it only for 1 map

[shadow owl]

Hey guys, does anyone have tips for using GSON to serialize native Spigot objects (like Location and an ItemStack[]) to strings that can be stored in an SQL database? I currently get errors about fields that are inaccessible, like Location's world Reference (java.lang.Reference)

[young knoll]

Custom adapter

[tall dragon]

yea make a type adapter to make it use the world uuid

[minor lark]

Hello everyone, I am getting this error on plugin load:

java.lang.IllegalArgumentException: unknown world
I have a location saved in the config, the plugin loads the world referenced in the location as soon as it loads, but the error still shows up... Any idea how to fix?

[lost matrix]

Yes, i can give you a simple example on how to write a custom serializer.

[shadow owl]

Would this be a custom typeadapator for the Reference, or for the Location?

[tall dragon]

for the location

[shadow owl]

That'd be helpful! I just haven't created a custom type adaptor before but I can probably find code on the web, that works too.

[minor lark]

If I add multiverse and softdepend it then mv loads the world before my plugin enables, but I don't really want to use mv

[tall dragon]

i always fix this with just having my own location object

only converting to bukkit's object when i need it

meaning the worlds already going to be loaded

[minor lark]

Ah, yeah wanted to avoid that

But if that's the only way

rip

[lost matrix]

public class LocationAdapter implements JsonSerializer<Location>, JsonDeserializer<Location> {
  
  private final Type typeToken = new TypeToken<Map<String, Object>>(){}.getType();
  
  @Override
  public JsonElement serialize(Location src, Type typeOfSrc, JsonSerializationContext context) {
    return context.serialize(src.serialize());
  }

  @Override
  public Location deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
    return Location.deserialize(context.deserialize(json, typeToken));
  }
}

You can use this adapter for any ConfigurationSerializable like ItemStacks.
It also works for Location[] or any Collection<Location> automatically.

Registering it on a Gson instance:

    Gson gson = new GsonBuilder()
        .disableHtmlEscaping()
        .registerTypeAdapter(Location.class, new LocationAdapter())
        .create();

There is another approach where you simply register a TypeHierarchyAdapter for the ConfigurationSerializeable interface, which simply
lets you auto serialize every Spigot object. But it requires reflections because your need to get the classes and then fetch a static method.

[shadow owl]

Interesting, thank you! It's good to note I can just use the serialize and deserialize methods. Also, what does "requires reflections" mean?

[lost matrix]

It means that you would have to use java reflections to wire a TypeHierarchyAdapter.
They can be tricky, slow and unsafe.

[icy beacon]

I normally write my gson deserializers fully by myself because I'm extra

[shadow owl]

Could I also just make a generic typeadapter for ConfigurationSerializable and then use casting when deserializing to map it back to the original object?

[lost matrix]

Nope, you dont have access to the static deserialize method that way

*Would need reflections

I mean... you could pass a Function.
Hm, let me just write something

[remote swallow]

not all classes are public, like item stack/item meta is package private so you would need reflection to access it anyway

[shadow owl]

So an adapter like this wouldn't work?

import com.google.gson.*;
import org.bukkit.configuration.serialization.ConfigurationSerializable;
import org.bukkit.configuration.serialization.ConfigurationSerialization;
import java.lang.reflect.Type;
import java.util.Map;

public class ConfigurationSerializableAdapter implements JsonSerializer<ConfigurationSerializable>, JsonDeserializer<ConfigurationSerializable> {

    @Override
    public JsonElement serialize(ConfigurationSerializable src, Type typeOfSrc, JsonSerializationContext context) {
        // Serialize the ConfigurationSerializable object
        Map<String, Object> serialized = src.serialize();
        return context.serialize(serialized);
    }

    @Override
    public ConfigurationSerializable deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
        // Deserialize the JSON element back to a ConfigurationSerializable object
        Map<String, Object> serialized = context.deserialize(json, Map.class);
        return ConfigurationSerialization.deserialize(serialized);
    }
}

[lost matrix]

ConfigurationSerialization.deserializeObject(serialized) this method doesnt exist

[remote swallow]

niether does deserialize

[lost matrix]

This is the best i could come up with, without using reflections.

public class SpigotTypeAdapter<T extends ConfigurationSerializable> implements JsonSerializer<T>, JsonDeserializer<T> {

  private final Type typeToken = new TypeToken<Map<String, Object>>() {}.getType();
  private final Function<Map<String, Object>, T> spigotProxy;

  public LocationAdapter(Function<Map<String, Object>, T> spigotProxy) {
    this.spigotProxy = spigotProxy;
  }

  @Override
  public JsonElement serialize(T src, Type typeOfSrc, JsonSerializationContext context) {
    return context.serialize(src.serialize());
  }

  @Override
  public T deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
    Map<String, Object> data = context.deserialize(json, typeToken);
    return spigotProxy.apply(data);
  }

}

Then register with:

    Gson gson = new GsonBuilder()
        .disableHtmlEscaping()
        .registerTypeAdapter(Location.class, new SpigotTypeAdapter<>(Location::deserialize))
        .create();

[tall dragon]

then u would just register one for each one u wanna use ? 😂

[shadow owl]

i know i was just updating it to match the deserialize methods i know do exist for certain concrete classes

[tall dragon]

i mean yea that works

[remote swallow]

they are static methods

static methods dont exist on interfaces

[lost matrix]

Yep, at least you dont have to create a new class for each

[shadow owl]

Neat, thanks!

[lost matrix]

    Gson gson = new GsonBuilder()
        .disableHtmlEscaping()
        .registerTypeAdapter(Location.class, new SpigotTypeAdapter<>(Location::deserialize))
        .registerTypeAdapter(ItemStack.class, new SpigotTypeAdapter<>(ItemStack::deserialize))
        .registerTypeAdapter(BoundingBox.class, new SpigotTypeAdapter<>(BoundingBox::deserialize))
        ...
        .create();

Looks fine

Hmm. ItemStack might need a registerTypeHierarchyAdapter because the impl is scuffed

[slender elbow]

wait until you find out none of those classes are final :^)

[worldly ingot]

Wait until you find out I extend ItemStack

[slender elbow]

Auxilor? Is that you?

[young knoll]

Just snbt it

:D

[sterile flicker]

why does it not work in inventoryclickevent to cancel the drop of an item from inventory java if(event.getSlot() == -999 || event.getSlot() == -1 || event.getAction().toString().contains("DROP")){ player.sendMessage(ChatColor.RED + "Cancelled!"); event.setCancelled(true); }

1.12.2

[shadow owl]

What makes you say that? It looks to have the same serialize/deserialize methods as others like Location

[young knoll]

Wait until you find out there are 2 ItemStacks

[shadow owl]

https://tenor.com/view/huh-cat-huh-m4rtin-huh-huh-meme-what-cat-gif-27377993

[lost matrix]

Just call registerTypeHierarchyAdapter for ItemStack.class instead.

[shadow owl]

Ok 👍🏼 I'd like to know why if you have the patience/time to explain

[lost matrix]

In short

[young knoll]

CraftItemStack

[icy beacon]

Has anybody worked with Commons Compress? I'm trying to read the contents of files in a tar archive. But entry.getFile() (entry.file) is null so I cannot read them. What am I doing wrong?
(trigger warning: kotlin)

private fun InputStream.asPack() = TarArchiveInputStream(this).use fullUse@ { tar ->
  var entry = tar.nextEntry

  while (entry != null) {
    println("Iterating over ${entry.name}. File null? ${entry.isFile} | Directory? ${entry.isDirectory}") // for pack_metadata.json gives "File null? true | Directory? false

    if (entry.isDirectory) {
      entry = tar.nextEntry
      continue
    }

    if (!entry.name.endsWith(".json")) {
      entry = tar.nextEntry
      continue
    }

    // irrelevant logic

    entry = tar.nextEntry
    continue
}

I'd like to avoid temp files if possible too ^^

[lost matrix]

The problem is, that the runtime class wont always be the bukkit ItemStack. It mostly is CraftItemStack.

This means that Gson looks for a TypeAdapter on the CraftItemStack.class which it wont find.
Registering a TypeHierarchAdapter instead of a TypeAdapter, lets Gson scan the entire TypeHierarchy for a viable adapter.

[echo basalt]

why do I feel like itemstack should've been an interface with a static factory method

[worldly ingot]

It should have been, yes

They all should have been direct proxies to NMS stacks

[shadow owl]

Ahh okay, thanks this makes a lot of sense

[worldly ingot]

Basically unless it's a new ItemStack(), it's a CraftItemStack

usually*

[shadow owl]

I assume there's a reason for the distinction?

[river oracle]

no, no there is not

well the reason is bad design I suppose

[shadow owl]

https://tenor.com/view/fell-gif-11242683397767497522

[worldly ingot]

One is a wrapper around an NMS item stack for more direct modification of item data, other is API

[dry forum]

is it possible to have a leash go between 2 locations

[young knoll]

Let's just uhh

Fix it

[river oracle]

atleast we got ItemMeta right and that's just NMS

that way ItemMeta can eventaully be fixed without destroying the API

[young knoll]

We just turn ItemStack into an interface

[river oracle]

Bytecode

[young knoll]

And then cry because of the constructor

[lost matrix]

You mean like this?

I used packets, which spawned invisible slimes. Then i made one the holder and the other one the leashed.

[dry forum]

yea

[muted dirge]

how to set a position for EntityArmorStand?? i cant find the method

Spigot NMS 1.20.4 (obfuscated)

[worldly ingot]

To be fair, could easily ASM that to ItemFactory calls

[worldly ingot]

It's either move() or setPos()

Depends on your mappings I suppose

[muted dirge]

neither exists

based on https://nms.screamingsandals.org/1.20.4/net/minecraft/world/entity/decoration/ArmorStand.html

[worldly ingot]

Yeah it should be moveTo()

NMS uses moveTo() anyways

setPos() might not send a packet to update the client. Unsure of the difference off memory

[gray holly]

Hey, is rhis message normal?
** „Reminder! All resources are the sole responsibility of individual authors and not SpigotMC. Access may be removed at any time. Please refer to the premium resource guidelines.“ **
And do i get it gernerally, or because someone took permissions to a plugin from me?

[worldly ingot]

Just a general reminder that plugins are not immutable and can be deleted from the website at any time

Be sure to download and keep up to date frequently if you want to continue using it

[young knoll]

Are you volunteering?

[worldly ingot]

No :)

[gray holly]

But, can the owner of the plugin, remove my Access? Also if i didn‘t do anything

[worldly ingot]

I don't believe they can

[gray holly]

Ok, because today at 10 am (mez) when i saw this in school, i was afraid, and had fear, that someone took me perms from a plugin, or thag i didnt had acces anymore to one plugin

[worldly ingot]

Oh, Yarn's mappings seem to imply that moveTo() does in fact refresh the position :p

setPos() does not

[young knoll]

They can only remove you manually if they added you manually

iirc

[muted dirge]

thank you so much, i think that would work for me

btw getWorld is called dM right?

[young knoll]

boo obfuscated

[worldly ingot]

¯_(ツ)_/¯

[young knoll]

Use remapped :c

[remote swallow]

looks like it

https://mappings.cephx.dev/1.20.4/net/minecraft/world/entity/Entity.html

[worldly ingot]

I can assure you that nobody here is going to remember obfuscated names by heart

[remote swallow]

illusion probably knows a handful

md probably knows them all from 2014

[muted dirge]

im lazy

im a dumb fu#k

[chrome beacon]

It would be less work to use remapped

[muted dirge]

I used
new EntityArmorStand(EntityTypes.d, nmsPlayer.dM());
instead of
new EntityArmorStand(nmsPlayer.dM(), loc.getX(), loc.getY(), loc.getZ());

😭

idk

[sterile flicker]

why opening an Inventory can call InventoryCloseEvent??

[rotund ravine]

If another is open

[young knoll]

If you already have one open

[sterile flicker]

I don't have inventory open, before opening a new one

[icy beacon]

I have resolved this by, unfortunately, resorting to temp files. I extract the entire archive to a temporary folder and read its files instead of archive's files

[sterile flicker]

can i force intellij to compile and to stop caring about errors?

[mellow edge]

when a player re-joins, is the new player object created or is the old one kept? if it changes I must literaly recode everything

well buckle up

cuz its a new one

[tall dragon]

the old one is stale after a re join

[mellow edge]

yeah...

[tall dragon]

why would u wanna do this ;dd

[inner mulch]

im refractoring stuff and just want to test while doing it but there are so many erros

[tall dragon]

pretty sure this is not an intellij thing

Javac simply wont allow it

iirc

[inner mulch]

😠

[mellow edge]

should I change everything to name strings or UUIDs

[tall dragon]

uuid's

[quiet ice]

Use eclipse

[mellow edge]

feel you xD

I haven't found the solution...

[chrome beacon]

Eclipse can just replace uncompilable methods with a throw statement

though I recommend just fixing your code

[quiet ice]

Eclipse will replace methods with invalid code with stubs to it's best effort, so evidence of a superior IDE here

[inner mulch]

i just want to test something while replacing stuff

fixing it is not an option currently

[tall dragon]

i mean. that is assuming you even should wanna do this

which is debatable

[quiet ice]

I mean you shouldn't use eclipse to build production builds anyways

So this behaviour won't sneak into prod at which point it is fair game

[eternal oxide]

You shoudl be using Maven so your underlying IDE doesn;t matter

[inner mulch]

yo guys which path do i need for hibernate configs?

src/main/resources/hibernate.cfg.xml <- this one good enough?

or does it look for the full path?

[eternal oxide]

that path is invalid at runtime

[inner mulch]

which path then?

[eternal oxide]

it depends on how you are packaging yoru jar

at runtime there would be no path, all resources are copied to your jar root

[inner mulch]

ok

i wasnt the guy asking the question so ping him

okay which is a correct statement, if u are using entities as reference have fun with your memory leaks, uuid's are better and this is not to discuss

yes im dumb

entity references are fine in 99% of cases

[pseudo elm]

guys one class per command or one class for every command?

[young knoll]

Yes but refrencing the entity/player prevents it from being GCed

[inner mulch]

one class per

[eternal oxide]

depends, but generally one per command

[young knoll]

And a entity/player not being GCed is more expensive than a UUID not being GCed

[pseudo elm]

isnt that gonna look stupid on a big plugin

[inner mulch]

no its not, single responsibility

[pseudo elm]

like one class for an /discord command

[inner mulch]

yes

1 class per command

[pseudo elm]

lua better

[inner mulch]

keeps it clean

[pseudo elm]

java too hard

[bleak eagle]

gotcha.. so that's why Player doesn't have a Player#setProfile but PlayerProfile had a PlayerProfile#setPlayerTextures

okay, still type erasure bad

okay nerd

yes but other languages have better generics

with no type erasure

[inner mulch]

everything except games I'd say?

[bleak eagle]

why no game

[bleak eagle]

they're such a mess

after working in several languages with generics pretty heavily

I mean you can make games in java if you really want to

[hushed spindle]

java just isnt good for games, minecraft should have never been made in java

My plugin creates custom worlds but when the server restarts they are unloaded. and if a player disconnects and logs in after a restart, they will be placed on the default world because the world they disconnected on is unloaded.

I've made all the code to load the world when you teleport to it and such and I know MultiverseCore loads every world on server start but I don't want to load every world right away, only if needed.

I tried loading the world on PlayerJoinEvent but I still get teleported to the default "world" world, where should I load the worlds instead or should I load all of them on server start? I'm afraid this might cause unnecessary lag to the server.

[young knoll]

You'd have to load them before the join event

[frank kettle]

PreLoginEvent is deprecated

[remote swallow]

async pre join event

[young knoll]

Maybe start the loading in AsyncPlayerPreLogin and block until it's done

You can block that event for up to 30 seconds before the client gives up

[hushed spindle]

i would assume world loading isnt fast enough to be doable on a playerjoinevent, you could teleport em to that world when its loaded or alternatively keep track of all the custom worlds players are in and only load those worlds

or asyncpreloginevent sounds good

[frank kettle]

ok i will try asyncpreloginevent

[frank kettle]

It seems the player location on AsyncPlayerPreLoginEvent does not save the world(It's saved as null so I can't use it to find which world to load), i will need to setup a local yml file most likely with which world each player disconnected on and then know which world it is to load on PreLogin 🤔

[young knoll]

There is no player location in that event

use the UUID with getOfflinePlayer and get the last location of said OfflinePlayer

[frank kettle]

I created a OfflinePlayer with it using the UUID

and then checked the location of the offlineplayer

yes, its what i did

wherever you initialize hibernate

ClassLoader old = Thread.curentThread().getContextClassLoader()
Thread.curentThread().setContextClassLoader(plugin.getClassLoader())
// .. initialize hibernate
Thread.curentThread().setContextClassLoader(old)

whether that be in onEnable or wherever

[inner mulch]

okay, plugin has to be hibernate in this case?

[slender elbow]

uh yeah, whatever thing is shipping hibernate

alternatively, hibernate might have a way to configure the classloader it uses

but idk about that

[inner mulch]

its a module, im not sure how i can access that

[slender elbow]

then just do getClass().getClassLoader

[inner mulch]

in onenable?

[slender elbow]

well, if it isn't a plugin it doesn't have an onEnable

that's just a way to access the current classloader

you'd do that in that separate module

[inner mulch]

i accessed the class loader and now i have an even bigger error

It's trying to use the hibernate reactive api

It's a separate dependency and you've probably told it to use it somewhere

How can there be a memory leak if you restart the application?

How exactly are you restarting

if you're using the spigot restart method then make sure to delay the startup a bit in your script so the server has time to stop

Please refrain from using single letter variables. Having descriptive names for your variables and methods is essential for clean code.
I would also reuse your variables instead of calling get-chains every second line.
It will make your code look much cleaner.

I usually only use single variables for things that either cannot be mistaken "p" or things that are used once "c"

[rough ibex]

p tells the user nothing

As an aside, call getItemMeta() once and hold it in a variable. It clones the ItemMeta each time you invoke it so invoking it twice just creates an unnecessary copy

It's also nullable for air, but if you're instanceof checking it to LeatherArmorMeta that's already covered

[rough ibex]

Yes, with a language

[rough ibex]

You set the key for it to ""

can you tell me what it's called

this inventory

[rough ibex]

no

Cant be that hard to find...

[sterile flicker]

container.inventory=Inventory?

or key.categories.inventory=Inventory

[agile anvil]

You should try both

But the problem with that is that you may remove the "Inventory" from every other inventory

One way could be to rename your chess inventory with a special character of which you assign a texture of a whole inventory, and maybe that can override the "Inventory" in the middle

[sterile flicker]

container.inventory=```

this is how to write in a .lang file?

or set to ""

[white root]

This is probably the better way to do it

You can't do that

can I set a texture for an item in the inventory?

the texture will be very large and will cover the entire inventory

[agile anvil]

As I remember you can't do that before 1.13 or so

The itemtexture would match the size of a slot

But I'm no expert, maybe you can try

atleast with the name as primary key you can't have copies but otherwise not much benefit

if i just do "new Case(player)", the case opens, everything is working. but if i remove it, the server crashes?

hi. I've imported NMS with mojang mappings to my project and used it, however, it says NoSuchMethodError when the method I've created which has NMS in it

[echo basalt]

oh cool the trap exception

[edgy crystal]

i dont know, it just crashes if i remove the item

[echo basalt]

been a while since I've seen it

[edgy crystal]

but the item is removed in the end

[drowsy helm]

                itemStack.setAmount(1);
                if (player.getInventory().containsAtLeast(itemStack, 1)) {
                    player.getInventory().removeItem(itemStack);``` bit of a conflict of interest

you're setting count then removing the item in the same tick, should do one or the other

[edgy crystal]

it was like that before:

                itemStack.setAmount(1);
                player.getInventory().removeItem(itemStack);

[drowsy helm]

why?

that doesnt really make sense whats the goal

[edgy crystal]

it only should remove 1 item

not the whole stack

[drowsy helm]

not how that works

you have to set the stack size

[edgy crystal]

ah, does it automatically remove the item if stack size = 0 ?

than i could do this:
itemStack.setAmount(itemStack.getAmount() - 1);

[drowsy helm]

no, itll look for an item stack in inventory that is 1 stack size

it doesnt remove just 1

yeah that should work

[edgy crystal]

ill try it

ah nice, now it works - thanks @drowsy helm

[quaint mantle]

now trying to set block using NMS, but I got this error
IllegalArgumentException: Cannot get ID of Modern Material

    public void setBlock(@NotNull Location location,
                         @NotNull Material material) {

        val x = location.getBlockX();
        val y = location.getBlockY();
        val z = location.getBlockZ();

        if (y < 0 || y > 512) return;

        val worldServer = ((CraftWorld) world).getHandle();
        val chunk = worldServer.getChunkIfLoaded(x >> 4, z >> 4);
        val chunkSection = chunk.getSections()[y >> 4];

        val blockState = Block.stateById(material.getId());
        chunkSection.setBlockState(x & 0xf, y & 0xf, z & 0xf, blockState);
    }```

[echo basalt]

val yikes

pretty sure you gotta createBlockData and get an nms version of that

I have something somewhere

Yeah

[quaint mantle]

how to convert it to nms thing

BlockData is a Bukkit class

[echo basalt]

val blockState = ((CraftBlockData) material.createBlockData()).getState();

[quaint mantle]

okay

thanks

[edgy crystal]

nvm, it works if i only have 1 item in hand, if there are 2 items (i mean the amount), server crashes

[echo basalt]

good ol' 1.16

[quaint mantle]

now it gives no error, but it doesn't place the block

    public void setBlock(@NotNull Location location,
                         @NotNull Material material) {
        val world = location.getWorld();

        val x = location.getBlockX();
        val y = location.getBlockY();
        val z = location.getBlockZ();

        if (y < 0 || y > 512) return;

        val worldServer = ((CraftWorld) world).getHandle();
        val chunk = worldServer.getChunkIfLoaded(x >> 4, z >> 4);
        val chunkSection = chunk.getSections()[y >> 4];

        val blockState = ((CraftBlockData) material.createBlockData()).getState();
        chunkSection.setBlockState(x & 0xf, y & 0xf, z & 0xf, blockState);
    }```

[echo basalt]

what if you relog

[quaint mantle]

still the same

does your code work?

[echo basalt]

Print out blockstate

if it prints something other than air it works

[quaint mantle]

Block{minecraft:diamond_block}

[echo basalt]

Then yeah it works

[inner mulch]

does someone know if hibernate operations are async or do i need to use completablefuture and stuff?

[quaint mantle]

so why am I not seeing it?

[edgy crystal]

for someone who also get this error, this is the solution:

                ItemStack itemStack = event.getItem();
                itemStack.setAmount(itemStack.getAmount() - 1);
                if (itemStack.getAmount() >= 1) player.getInventory().setItemInMainHand(itemStack);

[echo basalt]

Probably something changed in nms

[quaint mantle]

could you send your code?

[echo basalt]

I don't have anything to set blocks fast :)

last time I messed with blocks in nms it was uh

either client-sided blocks or hacky craftblock impls

I only have the top and bottom of the board displayed correctly

[echo basalt]

try making it a 1:1 ratio

[sterile flicker]

256x256?

[slender elbow]

sure

[quaint mantle]

I figured it out

here is the code if you want:
https://pastes.dev/P3ZOrdEGzN

[echo basalt]

yikes updating individual blocks

[quaint mantle]

280M blocks/s

tested it

[echo basalt]

I mean the block update packet

there are packets to update entire chunks

[tardy delta]

val in java?

[quaint mantle]

yeah, basically you have to cache the blocks and update it

[quaint mantle]

lombok

[echo basalt]

chunk update / multi block

[tardy delta]

since when can lombok introduce new keywords, compiler plugin?

[dry hazel]

compiler hack

[tardy delta]

and what does it expand into?

[echo basalt]

var has been a thing since java 12 iirc

[tardy delta]

im talking about val

[quaint mantle]

val is something like var

[tardy delta]

probably final var then

[quaint mantle]

oh really?

but is that okay for a single block though

[echo basalt]

it works

[lost matrix]

Maybe add a multiblock change method which lets you change multiple blocks and sends the chunk update packets

[young knoll]

Cries in api

[echo basalt]

maybe we could make a full multi block change api

and maybe add support for fake blocks

[young knoll]

I mean there is a multi block change api

[echo basalt]

there is api that wraps the multi block change packet

[lost matrix]

Isnt it about to be deprecated already?

[echo basalt]

but no proper 5 trillion blocks per second api

[echo basalt]

I pray

[sterile flicker]

if a player has taken an item from the inventory to the cursor, then inventoryclickitem should be called and inside I can get this item player.getItemOnCursor() or event.getCursor right?

how do I accurately determine when a player takes something into the cursor?

[shadow night]

Please don't compare items by name

[sterile flicker]

1.12.2 pdc?

there is no

[lost matrix]

You should create a layer on top of this.
Create a ChessBoard and an abstract ChessFigure, a ChessRuleset etc.
It will help you a great deal.

[shadow night]

Yep

And if you have a chess board class, you might be able to use it to not compare stuff by name

[sterile flicker]

I already have everything divided into many classes and there is no abuse of static fields

[lost matrix]

I dont see any use of those classes here.
Btw using a custom InventoryHolder is a pretty expensive way of handling custom inventories, because on every click the method getHolder() will clone the entire inventory again.

[sterile flicker]

what's wrong with comparing by name, i can't select an item in the inventory that is not a figure, and absolutely all pieces have a displayName

[rough drift]

someone can just name an item like that and put it in

[sterile flicker]

this is not allowed. I have a lot of conditions that disallow making "unacceptable moves"

[rough drift]

oh you can just make an acceptable move but add a new piece

there is nothing stopping that

[sterile flicker]

to add a item called as piece, need to close the inventory to take it, and the game will stop at the same time

[rough drift]

you don't need to close the inventory

[sterile flicker]

inventory clears at game start

[lost matrix]

Anyways. You should link this inventory to a custom ChessBoard class. And then create an instance of ChessPiece for every ItemStack on the field.
ChessPiece should be abstract so you can create all the other classes like Pawn, Queen etc. You should also give them a color this way.
Then do your entire logic with Board positions, ChessPieces and a fixed set of rules for the chessboard.

The spigot logic should be linked to this in a way that lets you write it once and never touch it again.

[rough drift]

you can pickup items

[sterile flicker]

I will cancel this event

[rough drift]

¯_(ツ)_/¯

[sterile flicker]

Thanks for the tips

[lost matrix]

PS: writing a proper chess ruleset is actually quite tricky. I would honestly just shade a chess library and simply link a board state to your spigot inventory.

[sterile flicker]

I have a chessmodel class that analyzes the list of available moves + stockfish

[rough drift]

WE MAKING IT OUT OF THE POSITIVE TPS WITH THIS ONE 🔥 🗣️ 🔥 🔥 🗣️ 🔥 🗣️

[sterile flicker]

It's justified, moreover, stockfish does everything asynchronously

[rough drift]

it was a joke

[young knoll]

/tick freeze

[blazing ocean]

hey, i'm trying to create a splash potion with an effect, i'm trying this:

            private val healthPotion = ItemStack(Material.SPLASH_POTION, 1).apply {
                val meta = itemMeta
                if (meta is PotionMeta) {
                    meta.apply {
                        basePotionType = PotionType.INSTANT_HEAL
                        customEffects.add(PotionEffect(PotionEffectType.HEAL, 1, 2))
                    }
                }
            }

and this just gives me these:

[rough drift]

you need to set the item meta after editing it

[blazing ocean]

thats what meta.apply does

[rough drift]

does it?

[chrome beacon]

cursed kotlin

[rough drift]

^

[blazing ocean]

💀

[rough drift]

yeah

you should like

set it.

itemMeta = meta.apply

[blazing ocean]

wait does it not do that automatically

[slender elbow]

no?

kotlin doesn't know how to do that

[blazing ocean]

oh 💀

i guess im dumb then

[slender elbow]

apply is just something that's called "scope function"

nothing to do with spigot

[bleak eagle]

any easy way to upload resources to textures.minecraft.net (programmatically) apart from skin uploads ..? I swear there was some weird thing with education edition a while ago.. might be a dumb question though

hdb clearly does this somehow-- as an example https://minecraft-heads.com/custom-heads/head/81948-warden-dye if you decode the base64 in the item data you'll see a valid textures.minecraft.net url

[echo basalt]

mineskin has an api iirc

[young knoll]

hdb makes you do it manually

First you have to create a Minecraft Skin. Focusing on the head portion of the skin.

You can design a completely new skin, or you can use an existing head as a base. You can download an existing head's skin file by going to the head page and selecting Download at the bottom.

To create skin designs, some people use programs like paint.net, Photoshop, and MCSkin 3D. You can also use free skin editors from sites like PlanetMinecraft, NovaSkin and The Skindex.

When your skin is finished, upload the skin to your Java Minecraft account, and generate a give code using our Head Command Generator.

Once you have created the give code, you can change back your skin without it affecting the newly generated head.

[bleak eagle]

ooooh okay

so skin changes is the way tldr

[young knoll]

Either that or you use mineskin

[bleak eagle]

it looks awesome but how do they do it

just a few accounts and then api requests to mojang to change their skins and get the texture value back?

since old textures stay after skin changes iirc

yeah they do, it's at the bottom of the page

there has to be a more convenient way ugh

https://www.reddit.com/r/Minecraft/comments/nv8xkk/comment/h621xvw/ almost certain this is the education edition thing I was thinking of

yeah so the game accepts *.minecraft.net URLs, not just textures.minecraft.net

[proud badge]

if I want to save the items of an inventory (like a player vault) is it best to just save an array of ItemStack

instead of Inventory

[inner mulch]

you can do both

but I'd just save an array of items

as this is the thing you want to store

[umbral ridge]

does ThreadLocalRandom only need to be initialized once? or is ThreadLocalRandom#current() always different and I have to reinitialize it each time I generate a new number?

[proud badge]

ok so I should just do private List<ItemStack[]> vaults; (list cause there are multiple vaults)

[mighty gazelle]

How to set this?

Example: (Please see it not for a AD)

[hazy parrot]

What

How do you reinitialize it

[umbral ridge]

ThreadLocalRandom.current() returns ThreadLocalRandom

since It's a static method It's kind of confusing

[inner mulch]

is PlayerSwapHandsItemEvent in an inventory called, if so seperately of a the clickevent?

[rough drift]

it doesn't create a new one @umbral ridge

[umbral ridge]

ok thanks!!

[rough drift]

it's a single instance, you can also set it by Thread.currentThread().setRandom() iirc

[mighty gazelle]

@EventHandler
    public void setMotd(ServerListPingEvent e) {
        e.setMaxPlayers(/*And here a STRING-Message*/);
    }

How to set this?

Example: (Please see it not for a AD)

[echo basalt]

you need to return an invalid version

[rough drift]

you need packets

also stop spamming

[echo basalt]

and set the invalid version text

p sure the event doesnt allow for that

also stop spamming

[rough drift]

^

[echo basalt]

and follow good habits (check pins)

[inner mulch]

e 😠
event 😃

variable names are important @mighty gazelle

[rough drift]

me naming it ev or the full event name

[echo basalt]

bad

blocked

[bleak eagle]

bukkitEvent

[rough drift]

Calm it was a joke

I wouldn't name it ev

[echo basalt]

name it eve

[mighty gazelle]

Okay

[inner mulch]

not naming it event is kinda cringe

[rough drift]

public void adam(And eve)

LOL

[inner mulch]

event is just the peak name for events

[rough drift]

serverListPingEvent

[inner mulch]

no

[rough drift]

mhm

[inner mulch]

ServerListPingEvent event;

this is peak

[bleak eagle]

you've said it four times

[rough drift]

ServerListPingEvent eventPingListServer;

[inner mulch]

because variable names are important

[umbral ridge]

I agree xD

you can't know what "e" is, but "event" you know that it's an event variable

[inner mulch]

yes

[umbral ridge]

"e" could be a variable for an exception, but I even name exceptions with "ex" or even exception sometimes

[inner mulch]

yeah variables help reading stuff

[mighty gazelle]

How can I make packets for this?

[inner mulch]

i've once seen some1 perform complex math with
double a
double b
double c
no one knows what happened in the method

[rough drift]

Google it

Jeka allows you to

it's a library downloading library
