Is there something like a "JsonElementArray" (i cant find one with that name) in GSON? I have a set of objects that I need to adapt to json

river oracle
#

Clear the caches

quaint mantle
#

I see "common" as a popular module name, but should I do the same in my packages for a non modular project

You are probably referring to JsonArray ^

ok thanks then

quaint mantle

np

#

I thought JsonArray was a list of JsonObjects not JsonElements

quaint mantle
#

Nah

#

Everything is a JsonElement

slender elbow
#

it's an array of any json element

#

could be an object

#

could be another array

#

could be a mixture of many element kinds, it doesn't have to be of one type

quaint mantle
#

It could be another list with an object

Does anyone know how to go to a new line after every line of lore when using a variable that isn't a fixed amount of lines? When using \n the next line just doesn't show

I tried finding the solution in this discord & with chatgpt, below is everything I tried but I don't think I understood it right so nothing worked.

            List<String> loreList = new ArrayList<>();
            //logic to add lines of lore

            //what I tried
            List<String> loreLines = Arrays.asList(loreList.toString().split("\n"));
            meta.setLore(Arrays.asList(loreLines.toString()));
            item.setItemMeta(meta);
            
            //also tried this
            StringBuilder stringBuilder = new StringBuilder();
            for (String loreLine : loreList) {
                stringBuilder.append(loreLine).append("\n");
            }
            meta.setLore(Arrays.asList(stringBuilder.toString()));
            item.setItemMeta(meta);```

ohh

alr

bleak eagle
#

i didn't include a pom.xml or anything

#

so your ide doesn;t even know it's supposed to be a spigot plugin

#

read the code and implement it inside your own plugin

#

we could've done some really fancy stuff with enumconverters and shit instead of defining the particle types you want by brute force but again i left it out for simplicity

#

once you understand the code you can implement it so that any particle type works without you having to have a huge switch statement

dont use a stringbuilder, append to your list instead

sand spire

yeah, i know how to get different lines of lore underneath eachother, but the problem is that my lore is within a variable that isn't of a fixed size, and I need to make splits within that variable, so I tried \n everytime I add something to that variable but that doesn't work

yes

  1. did you reload maven?

oh my god i'm an idiot

ive been trying to add dependencies but i havent been reloading maven and syncing

#

a list

#

StringBuilder will generate 1 String, not multiple

tender shard
#

your current lore looks like this

"line1",
"line2"
"line3\nline4"
"line5\nline6"

I had a list before but that didn't work so I changed it to a builder but I will change it back

A user of a plugin of mine tried to change the plugin's messages to cyryllic.

#

But it shows up like that

#

Does anyone know why?

tender shard
#

is the file saved as UTF8? How do you load the file?

grim hound
#

I don't do anything funny with it

grim hound
#

readLine

tender shard
#

then you have to specify a charset

grim hound
#

Is there a universal one?

grim hound
tender shard
#

show your code to load the file

tender shard
# 

import java.nio.charset.StandardCharsets;

  //...
  try (FileInputStream fis = new FileInputStream(file);
       InputStreamReader isr = new InputStreamReader(fis, StandardCharsets.UTF_8);
       BufferedReader reader = new BufferedReader(isr)
  ) {

      String str;
      while ((str = reader.readLine()) != null) {
          System.out.println(str);
      }

  } catch (IOException e) {
      e.printStackTrace();
  }

for example like this ^

grim hound
#

I don't specify it

#

In the InputStreamReader

grim hound
remote swallow
#

yeah

sand spire
slender elbow
#

Files.newBufferedReader ftw

#

utf8 by default api 🀀

grim hound
#

Tis how I do it

slender elbow
#

but even better is utf8 aware system by default 🀀

grim hound
#

But if utf8 supports all chars

#

Then wtf is utf16

wet breach
#

utf8 does not support all characters

tender shard
grim hound
#

It's an old piece of code

grim hound
#

So

#

How do I make it read what's actually there?

wet breach
# grim hound But if utf8 supports all chars

in utf8, characters take 1,2,3,4 bytes(8,16,24,32 bits) to encode a character. With UTF-16 its either 2 or 4 bytes. (16, 32 bits) and utf32 always uses 32bits to encode a character

grim hound
#

So I should use utf32

#

That doesn't seem to be a standard charset tho

wet breach
#

only if you know that the characters you are going to use will always take 32bits, IE chinese characters for example always do

#

and I think some emojis

wet breach
#

the number after UTF is how many bits minimum it uses

grim hound
slender elbow
#

just use utf8

eternal night
#

just use utf8

slender elbow
#

idk

you have to add that

I mean those a 3 separated maven projects but at the same folder

read the info at the top of the pom and add it to a dep

Each time I update the lib I need to change the dependency?

wet breach
#

hmmm

#

it is interesting that suddenly recently people have issues with using maven

#

you would think by now there is plenty of info out there in using it

wet breach
#

technically yes they are separate maven projects on their own

#

but if you use the parent pom, it should pull all of them up

or you can compile all of them using the parent pom

KISS, use as little external dependencies as you can

#

i'm sure there is some 'particle api' out there but there are many reasons as to why you shouldn't use dependencies for very simple things like that

you're counting on some random guy outside of your code maintaining it

hm is there a way to force a player to place a block

#

fuck it imma call bukkit events

#

im feeling angy

worldly ingot
#

There is not a way to force this, no

grim hound
worldly ingot
#

I've considered it a few times but I think there was a reason why it wasn't possible

grim hound
#

But you can't really physically force him

echo basalt
#

well

#

not necessarily force but call all the right events n stuff

#

or like get the block state, create a context n call the thing

#

but creatin a context is annoying as shit

grim hound
echo basalt
#

I think imma just call BlockPlaceEvent with a hacky injected block

echo basalt
grim hound
#

Tf is that

echo basalt
#

hm CraftBlock is not a final class

#

I think I've made a hacked craftblock before

worldly ingot
#

Oh dear

#

I don't see why you would ever need to do that though? PandaThink A block is literally nothing more than a set of coordinates and a world

#

It's a glorified Location object

echo basalt
#

to call a BlockPlaceEvent and see if things worky

#

basically this idiot customer configured her "custom block" as a feather and feathers can't be placed

#

and they can't change it from a feather because stuff breaks idk im not an expert

#

so imma hack something in so they can place a feather

#

it's just hacking in a new block, calling the event for region checks n placing it

#

no big deal

#

just a pain in the ass

#

I wonder if Location is final think3d

#

what if I extended the location class so location.getBlock returned the hacked block

#

it's not final let's go

river oracle
#

That means a block is just 3 numbers the truth is scary

hi, so I'm trying to make a task that runs basically every single living instant of a plugin, but anyways im trying to assign it to a variable known as scoreScheduler, now upon looking at the bukkit classfiles, it appears that this should work but it doesn't... can someone explain what im doing wrong?

the runTaskTimer variant that takes a Consumer yields void

replace task -> with () ->

bleak eagle
#

it's fairly simple - find their address, pull up to their house and hold them at gunpoint telling them to place the block

junior anvil

with intellij i go to project structure, artifacts and there i put my jar output dir
then i build the project

river oracle
#

if you compile with intellij it simply ignores your pom.xml configuration

junior anvil
#

OOOOOH

lost matrix
#

Alright, this will result in the pom to be completely ignored because you arent using maven.
When using maven you can only compile through the maven goals.
And never manually add any jars to your project when using maven. If you did -> remove them again.

After that: Click on your maven pannel and run package

You can sporadically run clean before package

okay so after working it out abit more, im aware that serializing class instances and transmitting them via the internet is generally considered a vulnerability for arbitrary code execution, is this still a major concern when the serialized object is transmitted encrypted like this: ```java
public class DataPackage implements Serializable
{
private static final long serialVersionUID = -6766450200075478944L;

protected PublicKey responseKey = null;
protected byte[] dataKey = null;

protected byte[] data = null;
protected byte[] hash = null;

<T> DataPackage(RSAEncrypter rsa, AESEncrypter aes, Serializer serializer, T data) throws InvalidKeyException, NoSuchAlgorithmException, NoSuchPaddingException, IllegalBlockSizeException, BadPaddingException
{
    this.responseKey = rsa.getPublicKey();
    this.dataKey = rsa.encrypt(serializer.serializeToBytes(aes.getSecretKey()));
    this.data = aes.encrypt(serializer.serializeToBytes(data));
    this.hash = MessageDigest.getInstance("SHA-512").digest(serializer.serializeToBytes(data));
}

PublicKey getResponseKey()
{
    return this.responseKey;
}

byte[] getDataKey()
{
    return this.dataKey;
}

byte[] getData()
{
    return this.data;
}

byte[] getHash()
{
    return this.hash;
}

}

altough the package itself is not encrypted?

How does one implement vanilla-like enchants in 1.20+ ? I've seen other plugins are able to add vanilla-like enchants to minecraft and have them appear in the enchant table and work fine with the anvil.

river oracle
#

have them appear in the anvil??

#

that's not even possible

#

@young knoll the lang files for enchantments are hard coded right I'm not going insane here?

wet breach

#

as if they were just another enchantment

river oracle

work in the anvil would include displaying the lang files in my mind

#

There is a method for inline comments too

vital sandal
#

is there any existed way for it

river oracle
young knoll
#

The lang files are not hard coded

#

But enchantments are sent over the network by numeric id

river oracle
young knoll
#

Sure but you can still change the names of enchantments

river oracle
#

since the registries aren't synced it has no clue what your enchantment even is on the client regardless of the numeric ID system

bright pelican
#

what would be the class name for a strength or like health tipped arrow?

river oracle
wraith apex
#

Can I just intercept the packet then? and change the name of the enchant?

river oracle
#

no

#

the client doesn't even know your enchantments exist

#

it can't interpret them in any capacity

bright pelican
#

can someone help me?

river oracle
#

still the only way to add them is to use the vanilla registry, unfeeze it and register your enchantment

Or use PDC and events for the table and anvil

You can just manually add it to lore

#

But if it gets picked as the hint in an enchantment table it’ll just appear blank

wraith apex
#

aye aye but then you need to restructure the lore

#

if lore already exists

young knoll
#

Just add it to the start of the list

river oracle
wraith apex
#

So in otherwords, adding an enchant to the registry is only good as a method for identifying the enchant on it

#

it's basically useless at displaying itself?

#

oh and adding the glow effect

Hello everyone! I am currently building a server with Mohist Bukkit and creating plugins.
When I modify the plugin, build it, and reload it, an error occurs. How should I resolve this?

where r the logs?

dapper scarab
#

maybe

the build task was failed

try to rebuild the plugin

Furthermore, my plugin operates normally again after I turn off and restart the server.

SpigotMC maintains the Spigot server. If you are using a fork of Spigot (such as Paper, Airplane, Purpur, or other derivative works), you should seek support in the appropriate Discord servers.

dapper scarab
#

instead of reload the plugin by PlugMan

river oracle
#

Mohist isn't support

Nor Is reloading

You can't expect stuff to work if you're using unsupported software and an unsupported feature

does anyone happen to know which packet updates the armorstand head post rotation on a client?

Rotation is part of EntityData, yes

Its this hybrid pos+rot packet

pos+rot is yaw/pitch

euler angles are in entity data

Ah he means specifically for the AS component

same for transformations on display entities

p sure you can use yaw+pitch on top of the quaternions

not on this setup

they're all mine and this is the first time I'm doing stuff with packets

echo basalt

look at this fool

prob only crashed his client like twice

torn shuttle
#

it looks like the packet is getting sent

#

I actually crashed my client exactly 3 times today

lost matrix
echo basalt
#

the answer is no, I can't place and the packet doesn't get sent unless the button is actually clickable

#

Now, let's see if any inventory events fire

#

cool the inv click event fires

torn shuttle
#

not going to lie this is the least fun way of developing this

echo basalt
#

now let's do a pro gamer move

torn shuttle
#

all nms and packets are doing in a library that gets shaded in

#

so I have to clean and restart everything every time

#

wait... radian to degrees maybe?

echo basalt
#

maybe

#

the angles I was setting are in radians

torn shuttle

I am pretty sure I'm using radian but

#

I think this might be requiring degrees

And windows is gonna update fuck

it's working

it's full async

and packet-based

#

so stop asking me to add that

#

now just missing using display entities

echo basalt
#

cool so @delicate obsidian @lost matrix Done some testing. While the slot is restricted in vanilla, it still fires the InventoryClickEvent

image.png
#

Unfortunately, if the item's not in the list, the button won't be marked as available

#

And it won't fire any confirm packets

#

I might be an idiot and need a bunch of iron blocks though

#

Ok yeah with iron blocks this works

#

cool

#

You'll still need to emulate all the slot functionality with the inventory click event

This is really cursed but achieves your goal so whatever

oh sit you're right

my bad

echo basalt

torn shuttle

hey I'm a man of laser focus, I was doing armorstands

I'm trying to make it so that the system scans for bedrock player automatically and serves either display entities or armor stand entities depending on that

fuck I gotta handle item merging

torn shuttle

oh that's blockdata? pretty sure I have to look at itemdisplay for horse leather armor right

#

never used these before

echo basalt

the transform

you fool

but yeah I use block data

torn shuttle

what's up with having a left and a right rotation anyway

echo basalt

No clue

smoky anchor

iirc it allows for something called "shear?"

" left rotation is applied before scaling and right rotation after scaling" says reddit

ok then

upper hazel

are display entities like armor stands in that it's a different packet to show items on the entity?

probably

you're setting it on the nms entity right

with like a craft mirror

oh I'm actually only doing craft for the itemstack, the entity is nms

wtf is that formatting

But yeah no you shouldn't use the equipment packet for items

btw fun fact in 1.19.4 the methods commented out give a class missing error but exist in the decompiled code, don't even ask me

echo basalt
#

imports

#

or sumn

#

cool I need to do shift click logic now

#

this is a fucking pain in the ass

torn shuttle
#

there's something busted with this

echo basalt
#

you're prob just sending the wrong packet

torn shuttle
#

basically the same thing runs for armorstands and that one works, all I did was remove the equipment packet

#

(and I tested it with that packet on too)

#

oh the plot thickens

#

I can see it on my test command

echo basalt
#

you're prob just doing something stupid

torn shuttle
#

starting to think it might be the scaling adjustments I was doing for armorstands, going to have to retest that

bleak eagle
#

one question: the formatting in spigot is all over the place
i've seen both

if ( condition )
{
  System.out.println( condition );
}

and (in my opinion better and more standard)

if (condition) {
  System.out.println(condition);
}

which one is actually preferred?

lost matrix
#

The first is primarily used if you have issues and just wanted to show that to everyone

smoky anchor
#

For Java it is usually the second one
(Also, I've never seen if ( condition ) with the spaces)

smoky anchor
bleak eagle
#

the entire builder class here, for example, has those weird spaces

#

i tried to follow it in my pr and work against my ide which prefers the second one

hybrid spoke
bleak eagle
warm mica
warm mica
bleak eagle
#

yeah same

#

i could do another pr to fix it though it might be deemed as unnecessary by md

warm mica
#

That's likely, it could also break existing prs

#

Bungeecord is similarly formatted if i remember correctly

bleak eagle
#

md himself probably writes that then

#

the funny thing is that Code Requirements in the craftbukkit readme propose sun/oracle coding standards, and those propose the second method without the weird spaces and line breaks

#

i'm assuming (at least that part of) the craftbukkit readme is kind of universal to all the other projects too

hm actually what do you guys think of isCompostable() api for Material

#

yay or nay / useful or useless

#

I could totally implement it in bukkit but I just don't know if it would ever get merged

tender shard
#

it should return the "level up chance" i guess, where 0 is not compostable

image.png
gritty current
tender shard
#

because you invoke "org.bukkit.inventory.ItemStack.getType()" although the return value of "org.bukkit.event.inventory.InventoryClickEvent.getCurrentItem()" is null

gritty current
#

it what file

tender shard
#

in line 27 of ReviveInventoryListener

bleak eagle
gritty current
#

what is wrong with the code?

tender shard
rough drift
tender shard
gritty current
#

no i send the code

#

i dont knwo how i can fix it

tender shard
#

you're calling getType() on the return value of event.getCurrentItem() even though event.getCurrentItem() returns null

gritty current
#

how would i then do it?

tender shard
#

check if event.getCurrentItem() returns null and if yes, do not call getType() on it

gritty current
#

ok

#

another problem

tender shard
# 
ItemStack currentItem = event.getCurrentItem();
if(currentItem != null) {
  // Now check if currentItem.getType() is a player head
gritty current
#

i have it so people cant take the items from the gui but i makes it so every gui i cant move stuff

bleak eagle
tender shard
#

no he's also doing some else checks

bleak eagle
#

kk

gritty current
gritty current
tender shard
gritty current
#

but how can i make it so people dont take the items from the gui but can stille from crafting tables and their inv

tender shard
#

by only calling event.setCancelled(true) if the inventory is your GUI

gritty current
#

how?

#

like this ?
if (event.getView().getTitle().equalsIgnoreCase(ChatColor.AQUA + "Revive A Player"))
event.setCancelled(true)

tender shard
#

you should rather identify your inventories by storing them in a set or sth

#

but yeah if you insist on using the title, then move the setCancelled into the if

gritty current
#

how would i make the set

tender shard
#

btw isnt that exactly the same?

image.png
tender shard
gritty current
tender shard
# 
private Set<Inventory> myGuiInventories = new HashSet<>();

then when you create a GUI inventory, add it to the set. In InventoryCloseEvent, remove the inventories from the set again

#

then in InventoryClickEvent you can just check if the set contains the current inventory

#

if yes, it's your GUI

gritty current
tender shard
#

you create the set only once and store it in a field

bleak eagle
#

@tender shard I can only make a PR in bukkit with a new method on Material, no need for anything craftbukkit, right?

inner mulch
tender shard
gritty current
bleak eagle
#

wouldn't something like that not need any implementation code?

inner mulch
tender shard
gritty current
bleak eagle
#

a big switch statement

#

just like for isBlock() and similar

tender shard
#

that stuff is auto-generated iirc

inner mulch
bleak eagle
#

don't habe the lini either

bleak eagle
#

I can't find any CraftMaterial class or anything in craftbukkit

#

although that might just be because I'm being dumb

gritty current
inner mulch
#

Okay, good

tender shard
inner mulch
tender shard
#

this is usually how a Material returns a value from NMS, by moving that method to UnsafeValues / CraftMagicNumbers

image.png
bleak eagle
#

but for my use I wouldn't need that, unless I were to retrieve the composter chance values from some nms class?

tender shard
#

i doubt it'd get merged if you just hardcode it into bukkit

bleak eagle
#

let's assume I was making a simpler isCompostable method similar to something like isEdible instead of something like getComposterLevelUpChance

#

what would that need to be merged?

#

just for examples sake I might make both

tender shard
#

well I'm not md5, i dont know if he'd accept a hardcoded thingy in Material, but I highly doubt it. IIRC all the values in Material are auto-generated and you should get any values like that from NMS. otherwise imagine the pain if MC gets updated

bleak eagle
#

yeah gotchu

#

do you have any clue on how it's generated? because if I just search the entire craftbukkit repo for isEdible which is similar to what I'm trying to do, the only thing returned is some test. so clearly there isn't a craftbukkit implementation for it, rather it's generated within bukkit (which it is, there is a big switch statement that returns true in case of edible materials and false otherwise)

#

I should maybe just look thru commits myself instead of asking you to do my homework but pointers are appreciated anyways

tender shard
#

@worldly ingot are all the values in Material autogenerated? Eg the huge switch/cases etc?

gritty current
#

in the forum he wrote Inventory.Handler but i can only find Holder

tender shard
#

that's his own class / interface

#

This means we will create an inventory handler object

lost matrix
gritty current
#

ahh ok

#

where do i put it?

tender shard
#

have you fully read his post?

gritty current
gritty current
tender shard
#

it actually explains everything

bleak eagle
#

in either case I was thinking of having an isCompostable AND getComposterLevelUpChance and then put a precondition into getComposterLevelUpChance to check whether the Material isCompostable. basically making it the programmer's duty to check if a Material is compostable before trying to get its level up chance. getComposterLevelUpChance returning 0 for non-compostable Materials implies that those materials are indeed compostable but don't level the composter up at all, and AFAIK there isn't an item like that in the game

tender shard
bleak eagle
#

thank you, that's quite useful

#

I could write some script to do it I guess

tender shard
#

so you could add sth like getCOmpostChance(Material) in CraftMagicNumbers that calls getItem on the material to turn it into an IMaterial and then just throw that into the static COMPOSTABLES map

bleak eagle
#

but then I'm being counted on to maintain those and what if I get a heart attack one day or something

ohh I see thanks

@bleak eagle are you going to PR the composter stuff?

bleak eagle
#

probably

#

unless you want to do it better than me because you're more experienced xD

whats up with everyone talking about composters today

bleak eagle
#

you started this lol

devout pivot

lol

# devout pivot lol

i was talking about implementing an api inside bukkit for checking whether an item is compostable

#

cuz that's not really possible right now

gritty current
bleak eagle
#

rn you need a big list of compostable items in your own code to check if an item is compostable

devout pivot
#

ye u hv to add an array or what not

Hello good, I hope you are all well and are having a nice day, I wanted to ask if you know of any spigot plugin which connects to Twitch, which serves to someone to donate me a X amount of bits can run a command on my server, so is the command of another plugin, I've been looking and have not found, and the few I've found do not have a good wiki or references, if you can help me I would appreciate it very much

no it gives me an error

lost matrix
#

Show the error then :=

bleak eagle
#

"it gives me an error"
"which error?"
"the error"

tender shard
#

lmao

gritty current
#

never mind

#

fixed it

#

it was bacause i had a lower case "i" XD

# devout pivot ohh I see thanks

casting in java is like converting one type to another. only Levelled types have the getLevel method we need. not all blockdatas are Levelled, so if we've made sure the block is levelled (only some are like crops and a composter, and we've already checked if it's a composter) we can safely cast ("convert") it to Levelled block data with the cast syntax (Levelled) boringNonLevelledBlockData

devout pivot
#

understood thanks

bleak eagle
#

make sure you don't cast if you aren't already 100% sure the BlockData is of a levelled block

#

it will just chuck errors at you

devout pivot
#

ok ill hv to filter out what block is being taken first then

bleak eagle
#

it's already done in the example

devout pivot
#

ye

bleak eagle
#

you just have to check if it's not a levelled block and then return early to stop your code from ever reaching the cast

lost matrix
#

For casting you should check with instanceof in >90% of cases

bleak eagle
#

in this case we only care about composters though

#

so we're checking material

#

not if it's a levelled block in general

lost matrix
#

Sure, but thats still a weak correlation

bleak eagle
#

we can be sure composters are levelled

devout pivot
#

how would i check if a block is levelled block without doing it manually like the example

bleak eagle
#

it's unnecessary adding the instanceof but you can if you'd like to additionally

bleak eagle
#

if (blockData instanceof Levelled)

hybrid spoke
#

just go the right way directly and check with instanceof

peak sapphire
devout pivot
#

ohh i see

bleak eagle
#

but remember that composters aren't the only levelled blocks in the game

hybrid spoke
#

very bad practice to go against the impl

devout pivot
#

ye ik

hybrid spoke
bleak eagle
#

it shouldn't ever lead to any weird behavior in my example, unless mojang randomly decides to make composters non levelled

Its one more check but i think its worth it
