Then its quite expensive. Get all Blocks around the player (NxNxN dim) and check the distance between the players AABB and every Blocks AABB.
Schedule this. You can greatly improve the performance while losing a little bit of precision by evenly distributing your scheduler over several ticks.

So instead of checking every player every tick you could check 1/3 of all players every 3 ticks in a round robin fashion.

[lost matrix]

Ah thx

Hm you might be able to change the friction of a block type via reflections...

[swift lark]

Sounds pretty complicated but if there's no other way I'll try that. Couldn't I also use the PlayerVelocityEvent? When you touch a honey block you slow down and if I permanently increase the speed of the player the event is called permanently, right?

[haughty granite]

from the config variable, how can I get the withdrawn option?

[remote swallow]

remove the getKeys(true) and make the variable a config section

then you can use .getString(path) etc

[naive bolt]

for withdrawn it would be ##.getBoolean("gizeh.withdrawn")

[haughty granite]

indeed it was all stupid, thank you

[remote swallow]

if its aconfig section you dont need the gizeh.

[naive bolt]

they asked "how can I get the withdrawn option? "

[haughty granite]

but yes it is indeed a boolean

[lost matrix]

    FileConfiguration configuration = ...;
    ConfigurationSection playerSection = configuration.getConfigurationSection(playerName);
    if(playerSection != null) {
      boolean withrawn = playerSection.getBoolean("withdrawn");
    }

[haughty granite]

getConfigurationSection("eventsMenuGUI." + slugItem)

[remote swallow]

yeah

[haughty granite]

I already have the gizeh via the slugItem

[remote swallow]

then call .getBoolean from that variable

[haughty granite]

yes ty

[rough drift]

Understanding it correctly, if I set a Damageable item's damage to 0 it will be at full durability right?

[haughty granite]

no need to set if(config.getBoolean("withdrawn") == true) ?

[rough drift]

nope

[lost matrix]

PS: constantly reading and writing from/to FileConfigurations is bad practice

[rough drift]

you should do config.getBoolean("withdrawn", false) though

[naive bolt]

I dont have the block

[rough drift]

as otherwise you risk checking a null value

[naive bolt]

only a vector

[haughty granite]

it is better to store it in an array at init?

[lost matrix]

You can get the block at a vectors position

[rough drift]

Also, a == returns a boolean, so if you already have a boolean, you can just pass it in

[naive bolt]

im pasting it so it would just be air

im rotating a clipboard

[remote swallow]

FileConfiguration config = getConfig();

just call it once where its needed and make it a variable

[rough drift]

But why?

getConfig doesn't reload it you know that right

it's just a variable

[lost matrix]

Then you have a matrix. Just do a matrix rotation and propagate the rotation to every
orientable / directional block.

[remote swallow]

it does

[rough drift]

It.. it doesn't

[naive bolt]

brain fried

[rough drift]

that's what reloadConfig is for

[lost matrix]

Ah dont worry. Just play around and find your own way. If it works in the end.

[rough drift]

newConfig is set in reloadConfig

[hazy parrot]

That is if config doesn't exist

public class SpawnProtectionHandler implements Listener {

  if (this.protected.contains(event.getPlayer()) event.setCancelled(true);
}

}

forgive me i havent wrote for bukkit api for a long time

but this is how i easily would implement spawn protection for a half a second

[rough drift]

you typed players instead of protected

also you should use player UUID's

otherwise this looks fine

[mortal hare]

why use player uuids for protection

i need player objects which are online only

[quaint mantle]

for half a second it wouldn't matter

[rough drift]

Because if a player disconnects the player object won't be valid anymore

[mortal hare]

it doesnt make any difference in this case

if he disconnects i would cancel the spawn protection anyways

[rough drift]

Also, it removes spawn protection after 0.5s

[mortal hare]

it should be removed

tho

[rough drift]

I mean I guess

That works then yeah

Still would use a UUID because of the hashset

I feel like UUID hash is cheaper to calc

[mortal hare]

true

[eternal night]

I mean, a players hashcode is just the uuids hashcode

but cached

soooo

evil people would say, the hashCode() function of a Player might be faster than a UUIDs

[rough drift]

I mean technically

[mortal hare]

it should be weak hashmap because it fails to clean stale uuids and objects or implement the player disconnect event to clean it up manually

too

its broken code, but i wrote this totally out of my head without any help 😄

[rough drift]

Me on my way to remove a player from spawn protection on spawn:

[mortal hare]

after not doing plugins since august 2022

[mortal hare]

wdym is the uuid hashcode saved inside the private field of player impl class?

[eternal night]

yea

[mortal hare]

is it initialized whenever server constructs an object or whenever you call the hashcode func for the first time

?

[eternal night]

its a lazy value

initialised first when needed

[opal juniper]

im lazy

[eternal night]

[mortal hare]

i actually never knew that hashcode is cached

good to know

but it probably depends on the server software fork too

since its not spec

[eternal night]

that should be spigot level

https://hub.spigotmc.org/stash/projects/SPIGOT/repos/craftbukkit/browse/src/main/java/org/bukkit/craftbukkit/entity/CraftPlayer.java#169

so, any fork should have that

[mortal hare]

man firefox have improved so much

[buoyant viper]

hashbrowns

[mortal hare]

its so snappy for me

and it supports css theming

you can make browser ui however you want

[buoyant viper]

has for a long time now

userChrome.css go brrrr

[mortal hare]

i use dark magic theme

from extension store

pretty simple but so nice looking

[quiet ice]

at the cost of increased chance of hashcode collision

[eternal night]

what

[quiet ice]

You can't easily fit 128 bits of data into a 32 bit integer

[eternal night]

eh

yes

but that same issue is on uuid

[quiet ice]

Oh, you're talking about using Players vs UUIDs on hashtables

[eternal night]

yea

[mortal hare]

collisions on hashtables are inevitable unless you have perfect hashing

[quiet ice]

or your input data is less (or equal to) the output data

And there is this neat little thing called entity id ...

So really one should use an Int2ObjectMap

[mortal hare]

yea but is not persistent afaik it depends on the players render distance, no?

EID is used for packets so it should be only for client syncing

[quiet ice]

I thought it would persist throughout the session, but don't quote me on that

[mortal hare]

im not sure tho

[quiet ice]

Since the server says the EID of the player on login

Or at least used to, no idea if it still does that

[eternal night]

entityId is not guaranteed to persist throughout a session

while spigot right now "ensures" it

vanilla re-creates the player when they change dimensions

issuing a new entityId

[quiet ice]

smh

             }
           }
         }

idk why for some reason It doesn't work

I noticed that bookPages is read as null

but I can't figure out why

[tawdry echo]

getConfig return correctly config?

[humble tulip]

book:
pages:
radompage:
- 'stuff in page'

Config looks like this?

Send ur config

[quaint mantle]

I didn't check that honestly

book:
pages:
- "page1":
- "line1"
- "line2"
- "page2":
- "line1"
- "line2"

my config

it's created on enable, by the saveDefaultConfig method ...

[sharp gorge]

Feel like this is a dumb question but i cant figure it out.
When i try to do this

                    String world = data.get(buttonworld, PersistentDataType.STRING);

I get an error in console

The found tag instance cannot store String as it is a NBTTagInt```

Its 100% saved as a string not an int.

[humble tulip]

That's a list of lists

It's not config sections

Wait no

That's not losts of lists

I'd advise you use a for loop and get string lists like book.pages.page + i

i starts frm 1 not 0

[quaint mantle]

thats what My code does actually

[humble tulip]

No it doesn't

Those aren't configuration sections

[quaint mantle]

for (String page : bookPages.getKeys(false)) {
List<String> lines = this.getConfig().getStringList("book.pages." + page);
for (int i = 0; i < lines.size(); i++) {
meta.setPage(i, lines.get(i));
}

I don't treat them as config sections

pages is a section

but it seems like the code is not entering the foorloop because bookPages gets assigned as null

[humble tulip]

-"page1" is not a key

A key has : after it

[quaint mantle]

can't it be a string key?

[remote swallow]

idk why you even have it setup like that

just add a string, it auto formats it per line

[humble tulip]

Just use sections that are a number

[quaint mantle]

a good idea

book:
  pages:
    - 1:
      - "line1"
      - "line2"
    - 2:
      - "line1"
      - "line2"

like that?

so numbers are treated as inetgers or sections?

[quaint mantle]

I need to control the content of each page separately

[dim bluff]

from https://www.spigotmc.org/threads/a-guide-to-1-14-persistentdataholder-api.371200/#:~:text=Custom PersistentDataTypes and,found here.

Custom PersistentDataTypes and how to use them ?
If you have bigger objects you want to store on your PersistentDataContainer, like UUIDs. For this you can simply create an class that implements the PersistentDataType and use an instance of that class as your PersistentDataType. Note that the returned primitive type has to be of one of the originally provided types in the PersistentDataType interface.

Why can't I just use a String?

to store the UUID in this case

[humble tulip]

Yes

[regal scaffold]

https://github.com/JEFF-Media-GbR/MorePersistentDataTypes
Use that instead

[dim bluff]

but again, why can't I just use a String?

[regal scaffold]

You can if you convert UUID to a string but storing UUID is not the same as storing a string

[quaint mantle]

i will try thanks

[dim bluff]

isn't UUID just a String?

[regal scaffold]

You have a bunch of choices, convert UUID to a string and store that, convert UUID to json object string and store that, store the UUID like it shows you in that guide you posted, or use the library I sent

It's not

[regal scaffold]

Otherwise you would be able to just store it "as a string" and there wouldn't be additional tools to do so

[hazy parrot]

Uuid is basically just bytes with string representation

And may also be representated with 2 longs

[dim bluff]

I was reading about that

[hazy parrot]

As its 128 bits

[dim bluff]

so I could convert

[regal scaffold]

These are all your options I’m pretty sure

[dim bluff]

do you know which one of these the library you sent use?

[regal scaffold]

The one I sent honestly the best you can store the UUID directly

https://github.com/JEFF-Media-GbR/MorePersistentDataTypes#:~:text=PersistentDataType<%3F%2C UUID[]> uuidArrayDataType %3D DataType.asArray(new UUID[0]%2C DataType.UUID)%3B

[dim bluff]

but the library should use one of this methods, right?

since the last one is just an abstraction

[hazy parrot]

Alex is converting uuid to byte array

[regal scaffold]

yes

Byte array

Ty goksi

[humble tulip]

Uuid is also 2 longs

[dim bluff]

so I can just convert UUID to a byte array than just go new String(byteArray, StandardCharsets.UTF_8) to convert it back to string when needed?

[humble tulip]

Yes

Or u can store 2 longs

[dim bluff]

To you more experienced friends: do you think this is overcomplicated or it's ok?

[humble tulip]

But if you wanna store in 1 key, go the byte[] metjod

No it's ok

[dim bluff]

you usually use it for what?

comparison? maths?

smth else

what's the good uses for the UUID, that's what I mean

[vagrant stratus]

HashMap<UUID, PlayerData> instead of HashMap<Player, PlayerData> is one use case, but you can use it for comparison in general e.g.

player.getUniqueID() == UNIQUE_ID instead of checking the name or display name

[winged anvil]

?paste

[undone axle]

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

[quaint mantle]

@humble tulipit still returns null hmmmmmm

[dim bluff]

just to clear out as I'm new to java, HashMap<UUID,PlayerData> prevents PlayerData changing if player change nicks, right?

[hazy parrot]

it will still be linked to same key, yes

[dim bluff]

I'm particularly traumatized by this because I lost a 50 dolar VIP once because I changed nicks...

[vagrant stratus]

Correct, UUID is constant regardless of player name changes or display name changes

[hazy parrot]

that is why you want to use uuid 😄

[dim bluff]

I'll start to aways use it instead of display name, when possible

[winged anvil]

does anyone have a price format function?

like that ex

[dim bluff]

I think java got one built in

[lost matrix]

I also remember some NumberFormat for currency

[lost matrix]

NumberFormat format = NumberFormat.getCurrencyInstance(); // Should probably a constant
double value = 120.50;
String formatted = format.format(value);

[haughty granite]

awesome I had almost the same thing, thank you very much

the fuck???

what is this currency symbol??

[lost matrix]

For a dollar sign you probably want the US locale.
"English" does not have country specific data. For that you would need UK or US

Locale locale = new Locale("en", "UK");

Should have a pound symbol

[haughty granite]

so it displayed me this symbol by default not finding the symbol of the locale "ENGLISH"?

[lost matrix]

Yes because ENGLISH is not country specific. Its just a language.

And languages have nothing to do with currencies. Countries do.

[compact haven]

^ they speak English in many countries

There’s plenty of stack overflow posts going off of the difference between Locale.ITALY vs Locale.ITALIAN

ok hold on, I need to make sure it's not erroring

[buoyant viper]

why wouldnt u check for errors before asking?

smh

[shut field]

how do you spawn an entity that you can make shift

Ohhh you do setSneaking, my bad

I was searching for "crouching" or "shifting" or smth

my bad

[idle loom]

this was an issue for a couple of days, I forgot to ask until now :(

ok
player.getInventory().remove(player.getInventory().getItemInMainHand());
Does definitely work, but I'm only trying to remove 1 from the player's hand

not the entire stack

ItemStack itemInMainHand = player.getInventory().getItemInMainHand();
itemInMainHand.setAmount(1);
player.getInventory().remove(itemInMainHand);```
Also removes the entire stack, instead of 1

[buoyant viper]

this is what i do in my plugin to just remove 1

item.setAmount(item.getAmount() - 1);
event.getPlayer().getInventory().setItem(event.getHand(), item);```

[idle loom]

Thanks, I'll try it

[shut field]

actually you can't spawn a player, so how does Hypixel do it that on that one win effect the entities are shifting?

I don't know of any other entity that can shift other than players?

[sterile token]

Players are entities, also mobs too

[shut field]

but you can't do like world.spawnEntity(loc, EntityType.PLAYER)

[sterile token]

What are u tyring to do?

[shut field]

I want to spawn an entity that can shift

[idle loom]

Thank you, that works perfectly

[buoyant viper]

they probably just make fake players with packets

or use Citizens to make npcs

[shut field]

hmm

[sterile token]

Yeah you ill have to use packets or depends on a npc plugin

[dim bluff]

how can I make p.setFlying(true); persist through death with pcd?

pdc?

[sterile token]

my bad, i forgot about them

[dim bluff]

so, any idea?

[remote swallow]

make a method that sets it setFlying true and a pdc key to true then on join/world stuff get the value of it and set it

[dim bluff]

gezz that's ugly

k

thanks

thought it had a better option like inbuilt player permissions or smth

[sterile token]

Why player permission 🤔

[dim bluff]

permission to fly

[sterile token]

Its an api, apis doesnt work like that

[remote swallow]

verano have you smoked today

spigot has permissions

[sterile token]

yes i know that

But why will be a flying permisison in an api 🤔

[dim bluff]

I mean, it's a game api

wouldn't be surprising

[sterile token]

Yeah but is suppoused to use it coding

[dim bluff]

it has a flying permission on the api actually

[dim bluff]

.

[sterile token]

That is not a permission, its a player property

[dim bluff]

so change permission to player property lol

sorry

[sterile token]

I mean the property is okay, i dont understand ur point - sorry tho

[dim bluff]

nvm

hey, what else can trigger property deactivation besides death and relog?

[remote swallow]

world change iirc

[vale cradle]

does bukkit pickup interact events on air? Like right clicking air

[dim bluff]

Any idea on why this code isn't working? It's reaching friend.setAllowFlight() correctly, it's just not working, on the same code I wrote p.setAllowFlight() and it worked, so it's not a setup problem

}catch(NumberFormatException e){
    String friend_name = args[0];
    if(Bukkit.getPlayerExact(friend_name) != null){
        Player friend = Bukkit.getPlayerExact(friend_name).getPlayer();
        if(args.length == 1){
            if(!friend.getAllowFlight()){friend.setAllowFlight(false);}
            else{friend.setAllowFlight(true);}
            return true;
        }

[winged anvil]

you should invert your conditions to do an early return for your if-statements lol

[dim bluff]

wdym?

[hazy parrot]

your current code is doing if friend cant fly, set fly to false, if he can, set to true

which makes no sense

[winged anvil]

example if (Bukkit.getPlayerExact(friend_name) == null) return blah;

code readability things

[dim bluff]

jesus christ that must be the problem, I'm coding for 12 hours, i'm so sorry

[torn shuttle]

rookie numbers

[hazy parrot]

don't be sorry, happens to everyone 😄

[dim bluff]

but can return return such a big code?

[winged anvil]

hm?

[dim bluff]

i think i didn't get what you saying

[hazy parrot]

he said that instad of nesting your if, you can just add early return to stop code from executing

[dim bluff]

that was the problem

[dim bluff]

ohhh got it

[winged anvil]

    public void onBellRing(PlayerInteractEvent event) {

        Player player = event.getPlayer();

        if (!playerIsInGame(player)) return;
        if (event.getClickedBlock() == null) return;
        if (!interactedWithBell(event.getClickedBlock())) return;

        onPlayerScore(player);
    }``` another example maybe?

[torn shuttle]

always stop the code from executing as soon as possible and never indent code if it's not absolutely necessary

[dim bluff]

nice tip @winged anvil

[winged anvil]

yes, this is what it would like like inverted ``` @EventHandler
public void onBellRing(PlayerInteractEvent event) {

    Player player = event.getPlayer();

    if (playerIsInGame(player)) {
        if (event.getClickedBlock() != null) {
            if (interactedWithBell(event.getClickedBlock())) {
                onPlayerScore(player);
            }

        }
    }
}```

[torn shuttle]

aka the hadouken school of programming

[winged anvil]

yes

[hazy parrot]

->

[dim bluff]

String friend_name = args[0];
if(Bukkit.getPlayerExact(friend_name) == null){ p.sendMessage(ChatColor.RED + "Player not found"); return true;}
Player friend = Bukkit.getPlayerExact(friend_name).getPlayer();
if(friend.getAllowFlight()){friend.setAllowFlight(false);return true;}
else{friend.setAllowFlight(true);return true;}

looking better?

[winged anvil]

yes!

[dim bluff]

haha, thanks again!

[torn shuttle]

you don't need that else statement

[dim bluff]

now i'll do this to the rest of the code... tomorrow... 23 PM now

[dim bluff]

oh sure

[winged anvil]

im hoping the braces n stuff is just cause discord lol

[dim bluff]

what?

[torn shuttle]

the formatting sucks

[dim bluff]

oh yes it sucks

[winged anvil]

yeahh i assumed so

[torn shuttle]

if you are using intellij you can download the sonarlint addon

which will yell at you until you either stop caring or become a better programmer

[dim bluff]

okay

[winged anvil]

yes

[dim bluff]

is this good enough?

[winged anvil]

yes

[torn shuttle]

yes

[dim bluff]

thank god lol

[winged anvil]

nothing major just small bits that'll make code much more manageable

will be helpful in the long run

[torn shuttle]

now you just need to learn to optimize it

[dim bluff]

you talking about what I just made or something else?

[dim bluff]

any books or youtube videos ( preferably)?

[winged anvil]

uhh just in general, making code easier to read

[torn shuttle]

probably tens of thousands, yes

[dim bluff]

i mean, any recommendation?

[winged anvil]

heres a video about this situation specifically https://www.youtube.com/watch?v=CFRhGnuXG-4&t=244s

[torn shuttle]

nope

[winged anvil]

basically says the same thing we just had you do but might be more understandable

[remote swallow]

1 nest is acceptable

[dim bluff]

I understood very well

[winged anvil]

0 nesting

[dim bluff]

actually i knew that but i'm kinda rusty

[winged anvil]

i write everything on one line separated by ;

[remote swallow]

You dont null check for loops on an inventory?

[winged anvil]

huh

[dim bluff]

I'd really like to get more tips and talk all night, but I really need to sleep, i'll only sleep 6 hours tonight, please feel free to dm me for tips, i'll really appreciate

[torn shuttle]

I forgot there was even a part of youtube dedicated to learning programming

I always thought that was objectively the worst place to learn anything concrete

[winged anvil]

if youre watching strictly tutorial videos yeah

[torn shuttle]

and he made a video called don't write comments, he's looking to start a war

[winged anvil]

prolly the realest video

[rotund ravine]

?

[torn shuttle]

I write very few comments, but when I do it's because there's a something someone should really be aware of that is not at all obvious

[wet breach]

I would say, you need to ensure comments are stripped when compiling as in some languages it can add to the size

but in regards to working in a team or group setting regardless if its open source or not, comments are really important

maybe you don't necessarily need them, but for others to understand it is

[torn shuttle]

imagine the api docs but with no comments

that would be fun

[river oracle]

I never comment my code, but I almost always document it

[gleaming grove]

This is basically his conclusion in this video, miniature is just an clickbait

[wet breach]

And are your projects being worked on in a group setting?

if not, then sure working by yourself its completely fine although recommended

[river oracle]

when I worked with a server over the summer yes

and the documentation was sufficent enough to ensure the team knew what the code did

no need to go and comment up everything

[wet breach]

I don't advocate to comment everything

but documentation comments and comments are virtually the same thing

I can read javadoc comments in source just as easily as a normal comment

however sometimes a normal comment is needed for things that are more internal

[river oracle]

only thing I usually comment internally are // TODO: [insert todo here]

[torn shuttle]

any annoying enough issue caused by a third party bug usually gets documented on my end

like the existence of fake players

for some of the checks or behaviors

[wet breach]

got to love them fake players

maybe I shouldn't have told people that such things were possible so long ago 🤔

[winged anvil]

thats when you should write comments

[torn shuttle]

I also have consistently regretted not doing more exhaustive documentation of my scripting solution

[wet breach]

at minimum that is what you should do, but in general you should make it a habit to document or comment your code

[torn shuttle]

mind you it hasn't lead to me actually documenting it, but i do regret it every time

[winged anvil]

just comment the code with code

[wet breach]

that isn't always possible or sufficient

[winged anvil]

yes true

then comment

[wet breach]

maybe you have duplicate methods, but the reason for it is because there is a catch somewhere

[winged anvil]

yeah if its not obvious then comment

[torn shuttle]

like my script targets system

that thing can run at least 5 layers deep from what I currently assume

[wet breach]

where I really would like to see more comments when looking at code

[torn shuttle]

but there's probably more ways to hack it together

[wet breach]

isn't so much on methods, but rather when people decide to create static variables

since it isn't obvious sometimes why it is even there

commenting on such things like that for example also helps you determine if what you are doing is even really necessary too 😛

[torn shuttle]

the singleton system for game engines makes me want to cry blood

[ancient plank]

My comments are typically just
// TODO: this sucks, pls fix tomorrow
To remind me what I was doing the day before

And then there's the javadoc comments

[torn shuttle]

godot has a hilarious singleton system too

[wet breach]

why?

unless you mean everything is a singleton

[river oracle]

My best comment on the server I worked for was

// god fuck paper
@SupressWarnings("deprecated")

[wet breach]

in which case that would get annoying

[torn shuttle]

no, not everything is a singleton, the implementation of singletons is just downright whacky

[wet breach]

ah ok

[torn shuttle]

basically in godot everything is a node, and so are singletons, you have to manually tell the program to load them on startup but they are just game objects like any other

they can run behavior on every frame, they can even delete themselves

[wet breach]

you know instead of supressing warnings you could just tailor your IDE to not warn you of those things

[torn shuttle]

they are present in the game hierarchy too

[wet breach]

interesting to have an object delete itself

[torn shuttle]

and if you want to access them you just make a static field of the type the class is and assign it to itself on startup

then you access the static field to interface with non-static data

[river oracle]

I do care about depreciation in most cases though however it's specifically most papers I couldn't give 2 fucks about

[wet breach]

just setup profiles

[river oracle]

I use spigot api for personal projects

[torn shuttle]

so yeah, whacky

also not sure I'm a fan of how godot does node scripts in the first place

it's not ECS, it's straight up inheritance where the script is the node, and therefore there can only be one script per node

dunno, still trying to determine if that's cool or just limiting

[wet breach]

Well interesting that objects can delete themselves

or that it is actually normal

I mean in C++ you can do this, but it isn't really a design principle you should use and only used in certain situations where the object is only needed for a very short time and then is tossed away

in which case an object deleting itself would be advised to just keep resources under control

[torn shuttle]

in game engines it's sort of necessary

we're talking about a scenario where realistically a single bullet projectile is a game object

you have to be able to get rid of these quickly and easily

but then again this scales very poorly in a lot of scenarios as you might imagine

[wet breach]

well sure, but typically you have management systems that would be responsible for such things, also it depends which side we are talking about

client side yes you would remove it from screen when its not needed anymore, that doesn't mean that at the same time the server stopped tracking it though lol

[torn shuttle]

I'm talking about game engines here, not client side vs server side programming

[wet breach]

game engines are for both client and server typically if we are not specifying which kind of engine

[torn shuttle]

I mean sure but I am just talking about games in general, not the specific instance where a computer across the ocean is dictating the game logic on your game

[wet breach]

if we are strictly talking about game engines server side, I can see some instances where an object deleting itself is necessary but your example above fits what I stated though

typically where you would want an object deleting itself is for those short lived ones that are only created for a very specific purpose and then are tossed away almost immediately lol

[torn shuttle]

I don't think I've ever made a script delete anything other than itself in godot

since it's all based on scenes

which are prefabs in unity

[wet breach]

well I am not all that familiar with godot so I can't really say on that

[torn shuttle]

even in a basic scene where you are stabbing an enemy there is an appeal in making it so the enemy handles whether it should still be alive after getting stabbed or not

ymmv but at a very basic level it should usually work out quite nicely

[wet breach]

one day I might look at it

[torn shuttle]

well it's free and it's the easiest install for game engines out there, considering it comes with a built-in code editor and is a fully portable installation

[gleaming grove]

I guess armorstand.remove() is example of self deleting object

[wet breach]

No, that method tells the world object to remove an entity. The world object has final say

[gleaming grove]

So unity and Godot works in that way

[torn shuttle]

unity isn't exactly the same

sort of

there's some nuance

[wet breach]

the only way the entity object could decouple from the world object is if the entity object had direct access to the map that the world was maintaining or if the entity object removed its own pointer/reference

the latter is basically what is being referred to as a self deleting object

where it removes its own pointer/reference in memory

[torn shuttle]

tbf we're getting into semantics here over whether the armorstand is not removing itself if it's deferring map access but has a method to do so inside of the object vs it holding a reference to the map and removing it itself

[wet breach]

lol

[torn shuttle]

who knows, maybe somewhere in the source code the free method for godot also defers access

[wet breach]

well at the very least you understand though 😛

[torn shuttle]

actually it probably does because some of the safer variants of it wait until a frame is done and it would just be silly to leave that up to the object all on its lonesome

[wet breach]

that would make more sense

but then again, I don't know godot or what exactly its purpose of creation was for. For all I know maybe someone liked the idea of self deleting objects that they made that it a normality of the language lol

[torn shuttle]

I can tell you they are losing sight of what made them rise to popularity imo

[wet breach]

that sometimes happens as languages mature

[torn shuttle]

I could be wrong because I just got to the party but it seems to be full of people new to game dev and mostly focusing on creating simple 2d experiences, but 100% of the focus for godot 4 thus far seems to be placed entirely on 3d capabilities

I guess they can't be known for being a good 3d engine until they develop those capabilities but man they are just not on the same playing field as something like unreal or even unity

and it would be weird if they were, considering unreal basically has infinite money at this point and isn't shy about dumping it into making the best engine they can

[wet breach]

don't see anything wrong with that except maybe how they might be going about 3d capabilities. Example being Minecraft. Minecraft doesn't have 3d models, it uses 2d models to then create 3d ones.

if that is how they are going about in regards to the engine stuff I could totally see me using such a thing

[torn shuttle]

well the focus on 3d came at a cost, you can't focus on everything at the same time

they used to support 5ish different programming languages, they dropped 3

including their homegrown visual scripting language which some of the art-focused devs were relying on

[wet breach]

well obviously not, but there is a gap in regards to 3d engines that use 2d models though because like some of the games if I were to make them really wouldn't require a heavy 3d engine and wouldn't really need to have 3d models. And just because you have 2d models doesn't mean you still can't make them look good 3d albeit you have some limitations of course. But the advantage of such an engine like this is you get more performance.

but these days though its all about them 3d heavy engines

sure they could support 2d models, but like now you have this entire bulky engine for such things that doesn't require all the bulk XD

but then again I come from a different era in regards to programming too

where optimizing for performance and size was a necessity and I believe it should still be so lol

[torn shuttle]

I mean it's still a necessity, people go for the heavy engines because a lot of the optimization work is deferred to the engines themselves

I've played around with some prototypes in unity and implementing LOD was as easy as following the naming conventions for the level of detail of my models

and it seems like in unreal you don't even need to do that anymore, they automatically handle LOD for you on a single base high quality model

that's a huge time saver, you can even go much higher detail without really having to worry too much about performance if the automated systems work

which by the way minecraft really should look into implementing LOD for far away chunks, there is no reason not to do it

there's even mods that do it for minecraft and they get stupid high view distances

[wet breach]

Technically minecraft already implements it

since LOD is something that shaders typically support

part of the problem with view distance in minecraft is that it is multiplayer and the fact that the server now has to accommodate these large chunk areas for each player. In most games they typically have pre-defined boundaries as well as pre-defined things going on in said boundaries

[torn shuttle]

I don't care if far away chunks have lazy loading that isn't instantly representative of changes, i'd take 200 view distance where things far away might've changed over 8 view distance of 1:1 representation

[wet breach]

I agree, but have to remember these modders have more time then the developers do in regards to any one specific thing

[torn shuttle]

if only this multi billion dollar franchise could hire the modders huh

[wet breach]

if I were to implement it, I would do lazy loading of chunks where entities don't spawn in until like view distance of 10 or something

but everything else could be visible

[torn shuttle]

I'm thinking of starting a kickstarter so mojang can afford to add more than five features a year

[wet breach]

its not a case of hiring the modders, you still have the same problem. In fact Mojang has purchased code rights to some things however not everyone wants to give up their rights to a project, as was the case for optifine

Mojang offered them a great deal on purchasing said project, but the developers ultimately declined

Mojang wanted to include optifine automatically into the client

[torn shuttle]

they don't need to buy the rights to modded code, they can hire developers to make their own in-house alternative to said code

[wet breach]

No they can't, this is how you end up with lawsuits

[torn shuttle]

optifine wasn't created by expending the one ring, you can apply the same kinds of optimizations optifine has without ever even looking at it

[wet breach]

so to ensure lawsuits don't happen it is actually typical to purchase the rights and possibly hire the one or ones that created it

[wet breach]

Sure, but why spend time on something that is already created and solves a problem that you needed solving in a better way.

[torn shuttle]

because it was solved for a single platform and only for people who mod the game in a specific way, which affects <.1% of your userbase

[wet breach]

but simply hiring the modders doesn't really solve the problem either, they could have budget requirements that may not allow for such things

and its a gamble in bringing in a modder. Just because the modder created something decent, doesn't necessarily mean they know how to work in a more professional setting or environment

[torn shuttle]

they are a multibillion game studio owned by a trillion dollar business

I think they can find some change in the sofa of their lobby

[wet breach]

doesn't mean they have multi-billion dollars to spend

remember, most of that billions went to mark/notch

doesn't mean minecraft re-made those billions since then

and yes, its owned by a trillion dollar valued company, doesn't mean microsoft has a trillion dollars, but regardless it has a lot of money it doesn't mean within the board they approve tossing a few billion at a game lol

or should say another few billion, technically the game didn't cost Microsoft that much

all Microsoft allowed was for Notch to take what Mojang had in its account really

which still counts as purchasing

so reality is the Mojang entity probably only has a few million in its accounts to actually really do anything, not factoring in payroll and other bills etc

[torn shuttle]

estimates put the revenue of minecraft at about half a billion yearly, not accounting for merchandising nor other games released under the minecraft banner

just game sales

and I can guarantee they make more from merch than from the game

I think they can spare some change and hire a few more developers

I wouldn't be surprised to find out all in all mc made > 1.5bil last year, minecraft merchandise sells really well

[wet breach]

not sure where these estimates got this, when Microsoft reported 69,447mil in revenue from their game division

Mojang falls under that branch, and if it was pulling half a bil or anywhere close I would expect it to be reflected in their annual report

instead total revenue before factoring anything else in was 198,270mil

that is the entire gaming division

anyways, I don't disagree with you though in regards that Mojang should implement some stuff, but at the same time when you don't have the funds to spend time on it because priorities lie elsewhere in Mojang, then not much the devs can do. Hiring some modders doesn't really fix the funds part

however what is easier to do is buy things though as those are single cost and not perpetual

so it makes more sense to buy optifine then to hire the developers of optifine to implement something like optifine. Since the code is already licensed the optifine devs wouldn't be allowed to use the same code from optifine in the MC code base and doing so introduces some legality issues. Like does that mean the developers don't retain the rights of their project anymore because they used code from it in another project they were hired to work on? This is why you buy the rights for a project so that if that does happen its a non-issue anyways as you own it 🙂

Anyways, enough of the technical talk in how game businesses get ran especially the larger ones as there is a lot of nuances to it. If anything, you are better off creating a custom MC client then you are hoping that Mojang fixes everything wrong lmao

who knows maybe they might make an offer to buy your custom client from you and start using that instead 🙂

[tender shard]

anybody got any idea why this regex doesnt match the empty line?

^\s*$ also doesnt match

[kind hatch]

It works for me. Although there isn't any highlighting. If that's what you were expecting.

It's valid regex, but I guess IntelliJ doesn't have any way to show it.

[tender shard]

lol yeah I am stupid, it even said "19 results". idk I expected it to mark the line anyways, because that's what it does when you select lines 282 to 284

then it marks the whole 283 lines as selected and I expected the search feature to do that too

[kind hatch]

I was also expecting it to highlight things and was confused when I didn't see anything. Then I started clicking the arrows to go through the results and realized.

[wet breach]

while it might seem you have found your issue, due note there is other tab characters that \t will not catch

fortunately it doesn't appear intelliJ is using those

[echo basalt]

They make a lot from merchandising

Source: I've probably spent a couple hundred bucks

[wet breach]

typical tab character is \09 however that is if you go by OEM codes. ANSI however has tab listed as \0160

regex typically doesn't catch tab as 160

fortunately however you can add character codes to your regex

^\t\o{0160}*$
^\t\160*$
^\t\x160*$ (sometimes doesn't work)
the preferred way is using \o{} as you can define multiple character points in the curly braces

due note if you use a character point code, it is case sensitive too, so like if you think it is a smart way to detect f well the character point for f isn't the same for F lol

[wet breach]

https://www.microsoft.com/investor/reports/ar22/index.html

if you want to see the real numbers

one of the handy things of corporations that have public stock is the fact they have to disclose earnings

downside is they don't have to make it easy nor do they have to separate the revenue of the divisions anymore then what is necessary

so you have to use some estimating

Then just do the index -> ahead method

Yeah but in engines like unity and godot there is no component for primitives. So you would
probably need to manually draw vertices there

it's 9:40 am, I was up all night and for some reason I am trying to figure out how to programmatically generate 3d meshes now

I should've just gone to bed hours ago

[lost matrix]

oof

3D only works if you have a proper scene setup with a position, direction and FOV. From then on its just
some maths and defining objects in space. But a "3D Mesh" sounds weird

[torn shuttle]

just a plane

with several vertices

[lost matrix]

Sounds pretty 2D to me

[torn shuttle]

it sure is, until I start animating the plane in 3d because that's the whole reason I need the vertices

[wide coyote]

why beetroots dont trigger the BlockGrowEvent? which event should I listen to

[earnest forum]

dont you need like a projection matrix

this thing

[torn shuttle]

no? in theory all you need is three points

at least for the most basic form of it

[drowsy helm]

if you are doing 3d you 100% need a projection matrix

keep in mind EventPriority.HIGHEST goes last

not first

[wide coyote]

yeah ik

[lost matrix]

Also check all your if statements. The code could stop at any of them

[drowsy helm]

so does the method not call at all?

do a quick println

nevermind user misinformation

it works

Also i would recommend:

    @EventHandler(ignoreCancelled = true, priority = EventPriority.HIGHEST)
    public void onGrow(BlockGrowEvent event) {
      this.autoHarvestManager.handleBlockGrowth(event);
    }

For single responsibility

Your listener does more than listen

Maybe some checks are fine but the bulk should be propagated

[dim bluff]

I wanna ask something aswell, should I write if (sender instanceof Player p ) as normal or should I make something to make it looks like if (isSenderAPlayer) and then Player p = (Player) sender;

[lost matrix]

former but without abbreviating the player

[tender shard]

TIL I learnt how CraftLegacy & Commodore works

[dim bluff]

k

[tender shard]

kinda interesting and so simple at the same time

[lost matrix]

Whats CraftLegacy? Never heard of that

[lost matrix]

Ah yes. Another fork. Haven't enough of those already.

[tender shard]

it's what makes e.g. 1.8 plugins that use 1.8 biome names still work in 1.19.3

or that lets old plugins that use WOOL instead of GREEN_WOOL continue to work

[lost matrix]

Always dreamed of that

[tender shard]

it's been in bukkit since 1.13

it's what prints this "Enabling Legacy Material support..." on startup when using old plugins or when forgetting to define an api version

[lost matrix]

"I whish i could write all my plugins using the 1.8 API because its simply superior" <- Me every day

Ah i see what you mean now

[tender shard]

basically it reads the whole class file's bytecode (e.g. EntityType or Biome, the bukkit that the plugin accesses), then translates certain constants, and then when a plugin gets loaded without an api version set, the bukkit classloader will throw the modifier version at the plugin's classloader

[lost matrix]

Yes i remember skimming that code.

[tender shard]

it's so simple but also so genius

is this proper english? lol

[lost matrix]

Makes sense to me

But im also from schländ

[sullen marlin]

Yes

[glossy venture]

yeah

[austere cove]

md do u know how the magic data values work for potions in ancient versions? 👀

[winged anvil]

lol this is the channel i sent @dim bluff earlier, such a fire channel

[dry yacht]

I had no idea that the NMS class MaterialMapColor existed, which basically stores all base colors from which you can generate the shades yourself. This is probably the most version-independent way of approximating map colors without the use of a deprecated, magic-numbers utility, xD.

[tender shard]

thx

[twilit roost]

I'm using this to hide player from tablist for some players
but this vanishes them completely

how can I make them still render to client?

[mortal hare]

i believe you can hide players from tablist by manipulating scoreboard teams

but im not sure, since i havent touched anything minecraft related for a long time

that's my bet

[halcyon hemlock]

search tutorial on spawning npcs, it uses like some kind of player teams or such ( as the person above stated ) to hide from scoreboard list. i reckon you can do the same to show it.

[mortal hare]

but if you hide it from tablist using teams of scoreboard api, you hide the physical nametag too

so you need to make some kind of nametag alternative, aka rideable armor stands to simulate nametags

[tender shard]

hidePlayer(...) and showEntity(...) might work

first, use spigot's hidePlayer to hide the player for everyone, then do showEntity (or hideEntity(..., false)) to all players again

that MIGHT work

[rough drift]

hidePlayer showPlayer

[tender shard]

then they would also see them in tab again

[dry yacht]

Regarding the section of "putting types in your names" (I know it was about identifiers, not class names, but still): Would you say that prefixing only a few select types with a single letter in order to instantly be able to know their type without having to go to their definition is bad practise? I usually do the following: E<name> for enums, I<name> for interfaces and F<name> for functional interfaces.

I'm kind of really having a hard time on deciding whether I should drop that habit or continue it, as I personally really like it.

[dry yacht]

Nevermind, just saw the following "Types in your types", lol. Well, I still like it, :(.

[tender shard]

i find it pretty useless. why would you care if something is an interface or a "normal" class, as long you can call the method on it that you need to call?

I mean you'd also need to call records RMyRecord

SFIMyStaticFinalInnerClass

I remember when spigot changed certain classes from interfaces to abstract classes, or other way around. yoU'd have to rename them everywhere in this case

[hazy parrot]

only reason i see for using hungarian notation is when making api to differ api classes (interfaces) and SomethingImpl

[rough drift]

Can I run Bukkit.getPlayer async?

[eternal oxide]

generally yes

[rotund ravine]

maybe, but not a good idea

[rough drift]

Dealing with some blocking operations, and I need to check because if the player disconnects I want to stop the task

var plr = getServer().getPlayer(uuid);
if(plr == null) {
    cancel();
    return;
}
```Basically this

[rotund ravine]

Can just hold a WeakReference to that player and if that is null they left.

Unless some other plugin holds a strong reference obv.

[rough drift]

Don't know, I just figured checking by UUID is best

[ivory sleet]

It should be alright

Since you’re just querying the map

[lost matrix]

In >90% of the cases you dont want to constantly start and stop tasks.
Have one task for all your players and if the UUID isnt in your primary data structure (eg if a player leaves)
then the task doesnt include the player in its iteration. This makes it easier for your initialisation and termination
of players. Usually a manager has onSessionStart(T element) onSessionEnd(T element) which simply
adds or removes the UUID from a data structure and propagates the element to all needed init/cleanup methods.
And you wont have to worry about managing tasks at all. Start once, let it roll.

[mortal hare]

any gradle users here

isnt using implementation dependency mode would be more reasonable when building spigot plugin instead of compileOnly one?

if so why not

[remote swallow]

implementation is the same as maven compile scope

so you would be shading spigot in is the simple answer

[tawdry echo]

can i send infinite title packet or i need to create task because i heare somewhere i can that

[tender shard]

you could use a very long time

however if another plugin sends a title, yours is gone

so you'd want to use a runnable

like once per second with fadeIn and fadeOut of 0, and duration of like 2 seconds = 40 ticks

[tawdry echo]

k

[icy monolith]

   public void onPlayerJoin(PlayerJoinEvent event) {
        Player player = event.getPlayer();
        player.teleport(new Location(Bukkit.getWorld("world"), -65, 75, 33));
    }```
Why would this not tp players to th spot when they join?

[remote swallow]

is the even registered and is it annotated

[tawdry echo]

better way to send actionbar is Player#spigot or packet?

[mortal hare]

both are doing the same thing internally (sending the title packet)

i would suggest player.spigot version since its cross-version compatible

less code to update after each minecraft version = better plugin

[icy monolith]

Wdym registered?

[mortal hare]

you need to register listeners

[icy monolith]

i must register each event?

[mortal hare]

no

you need to annotate each method with @EventHandler tag

[remote swallow]

you register each class

that has listeners in

[icy monolith]

ah ok

[mortal hare]

and register the listener class using PluginManager class

[remote swallow]

you can just register in onEnable

[icy monolith]

Bukkit.getPluginManager().registerEvents(this, this);
Something like this?

[mortal hare]

yes

[icy monolith]

what does "this" mean btw?

[mortal hare]

there are other ways to do that, but this is one of the easiest

[tawdry echo]

class when you do code

[mortal hare]

this keyword gets the instance of the class

you're writing your code

[remote swallow]

well wheres the listener

[icy monolith]

In main class

[mortal hare]

it could be implemented inside the main class

so this is legal

[remote swallow]

yeah that would be correct

[icy monolith]

Ok thx

what would happen if i change "this" to something else?

or a way to use it

is it like an argument to a function?

[ivory sleet]

this is a reserved variable within the scope of a class

[remote swallow]

its an instance of that class, if i have a listener in a class called MyListenerClass i would register the event like #registerEvents(new MyListenerClass(), this)

[ivory sleet]

and it points to objects constructed by that class

[icy monolith]

ok

[ivory sleet]

Welp, lets say that

[remote swallow]

thats exactly what i was thinking

[ivory sleet]

basically rousty

class A{
void method(A this, Object o){

}
}

[remote swallow]

[ivory sleet]

The A this part is inferred or implied

Therefore we usually don’t write it out

[icy monolith]

ok

[ivory sleet]

But its a reserved variable that contains the value as an object of the class

[mortal hare]

this keyword is very roughly just a private final field of the particular class, that has that class instance its currently executing it

[ivory sleet]

Ye

[mortal hare]

its internal implementation is different from fields

but it does the same thing

[ivory sleet]

I had to pick between some other ones, and they all were far worse

[icy monolith]

Ok thx

i think i understand it. Mostly its just there bc it has to be there

[mortal hare]

this literally holds this class object, its currently written in

[tardy delta]

Theyshoulve called it deez

[mortal hare]

private int num = 69420;

public void foo() {
  this.num = 0;
  // is the same as
  num = 0;
}

but with this keyword you avoid naming collisions

[ivory sleet]

anyway roursty its hard to fully understand what this means if you cant grasp the concept of objects and classes

[tender shard]

changing a final field?

[mortal hare]

for example if you have a method or constructor args which have the same names as the fields, this keyword helps you by specifying what field you're accessing

[mortal hare]

fixed

[icy monolith]

Class is like a file where you put the code and then inside of it your do the code which is functions and events and by adding events you must add a listener to thoes events and then register them using that line.

How i understand it

[mortal hare]

that's half way correct

events are not part of class spec

[icy monolith]

well you use a class to define it ig

[ivory sleet]

Yeah in object oriented programming yes

[mortal hare]

its just a way for bukkit api developers to allow you to add specific functionality when something happens

[ivory sleet]

But it doesn’t have to be a class

[mortal hare]

also in OOP we name functions as methods and variables as fields

but both names are really accepted because nobody gives a f

[icy monolith]

ok

[mortal hare]

is specific class runtime classpath used whenever you load the class at runtime from different java application?

lets say i use custom classloader

[ivory sleet]

A class is more or less also a template for creating a bunch of objects, moreover it can also be seen as a category of things, the class Dog is a category of individual dogs, and is the template to create new dogs.
Then for all variables, a variable also conforms to a type, or well category.
Dog dog; here dog is a variable, or some sort of container, that must contain an object/sample/thing from our class/category Dog. (There are some edge cases like, dog could point to null. But yeah)

[icy monolith]

i started learning 3 days ago so idk a lot of stuff but with help of chatgpt i think i know enough to do some on my own. Allready made an ore regen and force texture pack code just by that. Its just trial and error ig. I was using skript before this, prob dont know what that is.

[ivory sleet]

Nice

[icy monolith]

So what if its "BlockBreak"

[ivory sleet]

As in BlockBreakEvent from bukkit?

[tender shard]

a class is a blueprint of an object

imagine a cupcake is an instance/object and the cupcake form is the class

[tawdry echo]

how can i block item modifing in for example anvil by check nbt custom value

[mortal hare]

i started from skript too bro

i gradually transitioned to java tho

[icy monolith]

So its basicly just a blueprint.

[ivory sleet]

Thats one way to look at it

[mortal hare]

i started with skript, then flavoured it with some skript addons like skript-mirror, and eventually ended up ditching it for java

since skript-mirror literally exposes java stuff

[tender shard]

no need for NBT values, just use PDC

[tender shard]

yes

[ivory sleet]

Thing is, its not only just a blueprint

[icy monolith]

is it a blueprint of the code inside of the class or .....

[mortal hare]

1.14+ only

[icy monolith]

or just general actions

[pseudo hazel]

an instance is an actor and the class is its script

[icy monolith]

Instance is the code inside of the class right?

https://blog.jeff-media.com/why-you-should-use-1-8-8 (/s)

[pseudo hazel]

there are no events

[tender shard]

InventoryClickEvent if you want to prohibit taking it out or putting it into the anvil

however PDC tags stay intact when using anvils

oh you just wanna prohibit to use an item in the anvil when it has your data?

yeah then just prohibit it from being put into the anvil

[pseudo hazel]

oh so it like copies the data from the first item and adds the stuff from the second item to it?

[river oracle]

Do it lol

Id love to send that to people

[hasty prawn]

Please do it

[icy monolith]

Ok i understand now, but why would i put lets say onBlockBreak event inside of a class/blueprint and not just put it outside, if i wont need to use ``new <class>()? or are events only possible using classes.

Other than for events idk why i need the class. Can i just do the code without a class if it will not have any events inside of it?

[river oracle]

Uhhh I mean you could make a dispatcher than make a function to call within that dispatcher

But you need to have a listener somewhere

Java is inherently oop so I don't understand howd you do much of anything without objects

[icy monolith]

Well me too

idk

its wierd but it works

so i dont tuch what allready works

[river oracle]

Just stick to oop principles

When you code

[icy monolith]

Is it like classes in python?

Wait nvm

[ivory sleet]

🥲

[icy monolith]

that wouldnt make sense

Is it possible to put all of my code under one class? It wouldnt look good, but just asking so ik if that is possible

[remote swallow]

do it

[river oracle]

I mean sure but like no one would ever use your code and it'd be impossible to maintain

[river oracle]

Do it!

[opal juniper]

whats the best way for saving resources without the annoying:

[river oracle]

Never seen that error before must be because of my amazing s tier config utils

[remote swallow]

saveResource("somethinginresource.yml", false)

[hasty prawn]

Or y'know just check File#exists first

[remote swallow]

that too

[opal juniper]

could do that Ig

[opal juniper]

thats what im doing

wait

[river oracle]

I've never seen that before this is my save method no clue tbh

public static void saveConfig(final Plugin plugin, final FileConfiguration config, final String name) {
        try {
            config.save(new File(plugin.getDataFolder(), name));
        } catch (final IOException e) {

[knotty meteor]

Is it possible to add a enchantment on a player skull itemstack to make it "glow"

[remote swallow]

yeah

[pseudo hazel]

sure

[remote swallow]

just add it like normal

[river oracle]

Add like sharpness 500 to it or something to make it fun too

[pseudo hazel]

lmao

[remote swallow]

doesnt work in 1.17 or higher

they capped it to 255

[pseudo hazel]

i usually just add unbreaking 1 lol

[remote swallow]

its very sad that we lost 32k enchants

[fluid river]

anybody has snakeYaml experience?

[knotty meteor]

Its weird because it is not glowing the skull itself, i use EpicRename with /glow but it dont give the skull glow but it gives kind of the effect because the name is blue

[fluid river]

how can i basically make this work

[knotty meteor]

I also tried another glow plugin, but same iddue

[fluid river]

now it's just meh

[echo basalt]

you can't make skulls glow

it's client-sided behavior

[knotty meteor]

Ooofff

[echo basalt]

I discovered that like

on my first ever commission

YEARS ago

sad that mojang hasn't fixed it yet

[knotty meteor]

I never tought of it until i wanted to make a armor set wit hthis skull non enchanted and enchanted, but the skull wont glow

So oof it is not possible then :(

Objective objective = scoreboard.registerNewObjective("1", "2", "3");
Cannot resolve method "registerNewObjective"

registerNewObjective​(@NotNull String name, @NotNull String criteria)

when i do quick fix

it makes an objective

idk what now after it makes it

Hi, im trying to spawn a sleeping npc but somehow, when i execute the code, nothing happens. I use version 1.19.3 remapped. This is my code:```java
private ServerPlayer spawnNPC() {
