development

[atomic trail]

It's installed on server startup into the server directory called libraries

The PluginLoader is the only way right?

Or does that even download it into the libraries directory? Isn't that just for the jar

[dusky harness]

no - you could also do it even before the spigot libraries feature existed

such as by using slimjar

[dusky harness]

you can choose whatever directory so that it doesn't always download it every time the server starts

you could binary search the plugins

• delete libraries folder
• remove half the plugins
• see if kotlin appears
• if so, bring back half of the remaining removed plugins, and if not, remove half of the current plugins
• repeat

until you narrowed it down to 1 plugin

[atomic trail]

Yeah I wanted to avoid doing this, but it's probably necessary

[dusky harness]

wait hold on

why do you care about kotlin being installed

are you sure this is necessary

[atomic trail]

Having linkage errors, loader constraint violation

Basically it's a system of plugins where they MUST get the kotlin version from the core, which shades it, but they get it from somewhere else

I'm assuming the libraries from server as it's downloaded there and I've disabled all plugins that shaded kotlin

[dusky harness]

I'm pretty sure paper has isolated classloaders, and I assume spigot isolates the libraries as well (unless the plugins depend on each other)
if you remove all other plugins, then does the error occur?

[atomic trail]

Nope, it works when they're the only 2 plugins on the server

Wdym by isolated classloaders?

[dusky harness]

huh, interesting
I don't have enough knowledge about this stuff to figure out why 🙃

oh wait or maybe a plugin shades it without relocating

[atomic trail]

Well, it happens because EcoCrates must use the instance of kotlin which is provided by Eco (the core), but it gets it from the server libraries

[atomic trail]

I've disabled all plugins that shades kotlin, other than Eco

[dusky harness]

why not just have them all have kotlin in the server libraries?

[atomic trail]

Looked through all the jars and disabled all with the org.jetbrains.whatever package

[dusky harness]

kotlin uses the kotlin package

[atomic trail]

Some of the are premium plugins, which is very annoying

[atomic trail]

Yeah that's it

I think it's kotlindsl or something but yeah

I found the ones that shaded kotlin and disabled them

I think I'll just have to binary search for the issue and then work from there

And then hope that it's an easy fix

[dusky harness]

alr yeah for now that'll probably help identify the issue
but I just realized that this is a public plugin 🥲 so just saying "this plugin won't work with x" I feel like shouldn't be the final solution

but finding the problem plugin is a good step to finding the real issue

[atomic trail]

Yeah, because the plugins do work by themselves, it's when using them with more plugins that's the issue

[atomic trail]

Yeah probably the best plan

[dusky harness]

wait then how do EcoCrates get kotlin access

or wait

nevermind

[atomic trail]

It uses kotlin but doesnt shade it, it requires the instance from eco

[dusky harness]

I need someone who is experienced at php to help me add a login system to my litebans interface

[river solstice]

50€ and I can do it for you

[crystal reef]

i dont got that type of cash sadly

help a brother out man

please

[plain lagoon]

its very unlikely that you will find someone to do it for free

[crystal reef]

😔

[torpid raft]

time to learn some php it sounds like

php is a very marketable skill you wont regret learning it tbh

[crystal reef]

ye

any good sources to learn from that you know?

[river solstice]

yeah, internet

[torpid raft]

i dont know php, but in my experience you should not be overly concerned with finding the best source when learning something new

this applies to anything

[river solstice]

there is an abundance of information out there nowadays, your job is to pick one and start from there

WHAT IS THIS

This video has been removed for violating YouTube's Terms of Service@stiff cape

[shell moon]

(It was a fake Free nitro with scam link)

Yeah, his account was hacked xd

[swift portal]

I'm using Skript to make "soulbound" items with a specific lore line not drop on death and be returned after respawn. The skript saves and gives the item back correctly — that part works.

The problem is: the item still drops when the player dies.

    set {_uuid} to victim's uuid
    clear {soulbound.items::%{_uuid}%::*}
    loop all items in victim's inventory:
        if lore of loop-item contains "&8(&7Soulbound&8)":
            add loop-item to {soulbound.items::%{_uuid}%::*}
            remove loop-item from victim's inventory

on player respawn:
    loop {soulbound.items::%player's uuid%::*}:
        give loop-value to player
    delete {soulbound.items::%player's uuid%::*}```

can anyone help solve this issue?

[weary finch]

remove loop-item from drops

@swift portal

https://docs.skriptlang.org/expressions.html#ExprDrops

[swift portal]

Could you fix it for me, I'm confused

[weary finch]

    set {_uuid} to victim's uuid
    clear {soulbound.items::%{_uuid}%::*}
    loop all items in victim's inventory:
        if lore of loop-item contains "&8(&7Soulbound&8)":
            add loop-item to {soulbound.items::%{_uuid}%::*}
            remove loop-item from drops

on player respawn:
    loop {soulbound.items::%player's uuid%::*}:
        give loop-value to player
    delete {soulbound.items::%player's uuid%::*}```

Victim is already dead so the item has dropped

so it went into the items dropped method

[swift portal]

Ok thank you ill try htis

It still drops

@weary finch

[weary finch]

    set {_uuid} to victim's uuid
    clear {soulbound.items::%{_uuid}%::*}
    loop drops:
        if lore of loop-item contains "&7Soulbound":
            add loop-item to {soulbound.items::%{_uuid}%::*}
            remove loop-item from drops

on player respawn:
    loop {soulbound.items::%player's uuid%::*}:
        give loop-value to player
    delete {soulbound.items::%player's uuid%::*}```

Try now @swift portal

[swift portal]

still drops and now it doesn't go back to my inventory after death.

@weary finch

[weary finch]

Ok, go back to that previous

[swift portal]

Any idea on why this doesn't work?

[weary finch]

You could ask skript discord

[swift portal]

Alright will do thank you!

Same problem — when you go to the repository in browser, it says "Not Found."

Where should Maven find the file when there's nowhere to download it from?

[hushed badge]

in browser u need the /#/ to view the index, maven will find it from the link above

okay, i downloaded and will add with local lib

why?

the repo is literally there

ok

did u refresh the dependencies after adding the new repo?

[neon pewter]

I already assign default value to the interface but why there still warning that calling fetch can return null ?

[sterile hinge]

The warning isn’t about the return value of the fetch method but of the getAnnotation call

I guess it‘s not smart enough there to understand the previous if covers that

[neon pewter]

oh i checked and get annotation is nullable so i guess that is where the warning is

Hello im currently coding and doing a texture pack to go with some custom items that i am making im running it all on 1,21.4 so doing texturepack since the change this is a first and its invisble wonder if anyone cant help https://paste.helpch.at/vabalojago.json and heres how its all laid out https://imgur.com/a/Tjqa6fY

[peak flame]

Hello everyone,

I'm not sure if this is the correct channel for my question .. please let me know if I should post elsewhere.

I'm trying to disable the highlight for inventory slots, or ideally, make it so that the highlight appears only over the item itself within the slot (see this example: https://gyazo.com/8c0f6208a12bdda3e8041569a84514af).

I've seen several Minecraft servers implement this, but I haven't figured out how to achieve it. Any guidance would be appreciated!

[quaint sequoia]

Are you using https://itemsadder.devs.beer/ ?

Cause that pic is 100% made with ItemsAdder

[peak flame]

No Thats a screen shot from a server (not mine) and for my own gui I am not using itemsadder

[quaint sequoia]

I'm saying that the server you took the screenshot on is using ItemsAdder

[peak flame]

I am using my texture pack with my own plugin that I am developping

[quaint sequoia]

That's how those servers are making custom GUIs like that

They're not just changing the texture of the inventory

[peak flame]

Oh so the item highlight thing is linked to itemsAdder?

[quaint sequoia]

What they do is that they change the way a font looks for special characters and then they just show those characters
So instead of fx.
$ being $ it would show an image

does that make sense?

[peak flame]

Coz I know how to add a custom texture ... it's just that the slot highlight is annoying and ruining the menu I made (ok leme reread what you wrote)

[quaint sequoia]

so the menu is actually the inventory title text that is covering the whole inventory

and thats why the highlight isn't shown

since the "image" from the custom font from ItemsAdder is covering it

same way that ItemsAdder can give you custom emojis in chats. It's just a special character that they've changed the font of

This is an example from their docs

smile:
  permission: smile
  show_in_gui: true
  path: "font/emoji/smile.png"
  symbol: "鄿"
  scale_ratio: 9
  y_position: 8

then here the symbol is changed to the image

so the image is shown when you type the symbol in chat or show it in the tablist etc

as the font itself is changed

They change it with a resourcepack tho, so you could technically do it yourself

[quaint sequoia]

https://itemsadder.devs.beer/plugin-usage/adding-content/font-images-advanced

[peak flame]

I know how to add custom textured Items and the texture for the gui. All I'm struggling with right now is the hover animation on an inventory slot that is limited only to the borders of the item's texture. And not the whole item slot.

here is another example of me hovering the sorting button https://gyazo.com/ab326625ccff48e0fa76b69f9af8be06

[quaint sequoia]

Imagine you have a font, and you wanna change how the letter A looks

now imagine that you put a picture on that A instead of a normal bitmap font looking A

Now imagine if you scale that image so it's way bigger than what the A originally was

Now you got a font with an A that looks like an image, and this way you can cover the whole menu with just a symbol

the image you sent is the exact same. Here I'm just guessing that they're ofc still putting a ui over the inventory so that the vanilla highlight is being covered, and then they just put an item in the menu with that texture and move the item around

Notice how big the gap is from the coin and up to the "infinibag"

that's cause the top row of the inventory is in between

[peak flame]

Damn okay I am not sure I understood you fully. I don't know how I'll be able to implement that in my own plugin + texturepack without relying on itemsadder

[quaint sequoia]

It's not the easiest thing no

Does anyone have experience with/know if its possible to have custom models (something like ModelEngine) appear on bedrock with geysermc?

Hi

[dense galleon]

When trying to use Protoweaver in my paper backend server, I get this error here: https://paste.helpch.at/ajeyoxofoh.php

Does it look like it would be an issue with the plugin itself, or could it be something with my docker containers?
Just by a quick glance
i tried investigating, and when looking into https://maven-central.storage-download.googleapis.com/maven2, it does give an error
So could it be that the dependency's repository has been moved?

[weary finch]

Can we see how you are importing the maven in your gradle?

[dense galleon]

It's not my plugin, and the issue is with a library of that plugin

[weary finch]

The issue is with what you said. If you try to go to https://repo1.maven.org/maven2/org/bouncycastle/bcpkix-jdk18on/1.81/ - it posts. However if you go to https://maven-central.storage-download.googleapis.com/maven2/org/bouncycastle/bcpkix-jdk18on/1.81/ it does not

No such object: maven-central/maven2/org/bouncycastle/bcpkix-jdk18on/1.81/

[dense galleon]

I don't understand what I am meant to be doing then, I'm sorry

[weary finch]

You can ask the dev to fix it. Only real fix

Which plugin is it

[dense galleon]

Right, he's MIA though

Protoweaver

[weary finch]

What version and what platform are you using?

[dense galleon]

Paper, 1.21.7

[weary finch]

Im going to import the project on my intellij and see if any issues arise

[dense galleon]

Yeah I have been trying to do that too

There isn't any issues whatsoever though

From what I can tell

I've been at it for two hours, if you find anything lmk

[weary finch]

Did you try building it? it might be an issue with his maven

[dense galleon]

Yeah I have

It builds fine

[weary finch]

same error?

[dense galleon]

Nope, no error whatsoever when building

[weary finch]

No I mean when running the build

[dense galleon]

Oh, yeah it's the same errors still

[weary finch]

Ah, Its a paper issue

[weary finch]

Simple issue is to require the libraries but import from the jar

[dense galleon]

What do you mean? Like, have the .jar in the plugins folder?

[weary finch]

No

[dense galleon]

What do you mean then?

[weary finch]

Nvm, I found the library

https://repo.papermc.io/#browse/search=keyword%3Dbcpkix:3328a896b4babfd0bca068bdf208b48b

bouncy_version=1.81

papermc is on 1.75

change that to 1.75

https://repo.papermc.io/#browse/search=keyword%3Dmrnavastar:45682caac9e36bf388a7af773925bd5c

and well his is uhhh blank

so it wont work even with the fix

https://repo1.maven.org/maven2/me/mrnavastar/r/1.0.9/
as you can see paper hasn't added his repo correctly

[dense galleon]

Are you saying to rebuild it changing the version to 1.75?

[weary finch]

in plugin.yml and gradle.properties, Change it to 1.75

Like I said, That wont fix it though because his repo on paper does not include his library

[weary finch]

as you see here, Its only the pom.xml

[dense galleon]

Right, so I should just wait for him to fix it then? :/

do any1 of you have bitcoin mining programs to mine ? or any people actually mining ?

[true ember]

I’m still a beginner Java coder but is passing the main plugin instance as static as bad as people make it out to be?

[torpid raft]

it wont cause your house to catch fire

it's just against best practices / oop

[crisp star]

Don't do it it's going to create a supermassive black hole in the center of the planet

[dry summit]

i dont recommend this to u have much other options as getting it in a static way

[torn heart]

general "issues" with static/Singleton patterns

but tbh like

it doesn't really matter

it's literally against best practice to reload the server anyway or to mess with plugins being disabled at runtime

which is when this would cause an issue anyway

[torn heart]

like I wouldn't really necessarily say any of these apply to JavaPlugin instance

you already don't have control over its lifetime

[dense galleon]

If I have 5 plugins that all depend on a Core plugin, and all five of those also require TriumphCMD, am I better off shadowing it in my core plugin's API jar or shadowing it in each plugin?

[peak stirrup]

I guess you could try to shadow it, some plugins cause massive JAR sizes when shadowed, for me when I shadowed PacketEvents into a core, the jar was 4MB when standalone its like 240kB. I'm not as experienced as a lot of people here, but personally I don't like it cause as I said it causes massive jar size increases

[torn heart]

look at shadow documentation

you can exclude everything you don't need

and you can legit js unzip jar files to see what got included if you're not sure

don't even need decompilation

[dense galleon]

Does anyone know if BaseCommand has been removed from triumphcmd in 2.0.0-BETA-3?

[peak stirrup]

how much extra work is it though? as ive said I am no expert still learning so tips are welcome 😄

[torn heart]

google it

[proper hull]

What is the way to register a simple %example%?

(I have the placeholderAPI 2.10.9 dependency LATEST)

[icy shadow]

it's something i try to avoid

sometimes you need a Plugin instance but you should always try to avoid needing your plugin class

3500 lines so far and zero dependencies on my JavaPlugin instance

[broken elbow]

1. 2.10.9 is not latest version of PlaceholderAPI.
2. You can find documentation on how to create a placeholder, right here: https://wiki.placeholderapi.com/developers/creating-a-placeholderexpansion/

[proper hull]

thanks

[torn heart]

why

is there like a concrete reason

don't just throw SOLID at me 😭 cause that shit controversial

[icy shadow]

Well because of the reasons you mentioned for one thing

[torn heart]

which ones

I said they were invalid with java plugins

[icy shadow]

These

Nah I disagree

[torn heart]

how do any of these apply here

[icy shadow]

It’s really easy for your plugin class to end up being a god object which is inherently bad design

[torn heart]

#1 and #2 I don't think apply to the literal Java plugin instance

[icy shadow]

Especially when trying to do automated testing

[torn heart]

what do you need to get exposed that's different with automated testing

like what do people use that for

[icy shadow]

well if you avoid needing an instance of your plugin then you don’t have to worry about getting an instance in a testing environment

[torn heart]

also @icy shadow do you never use Kotlin Objects then (if you write Kotlin)

[icy shadow]

I try to avoid it where possible

[torn heart]

well I mean

I actually don't get this

why does that change with static vs. passed plugin instance

[royal hedge]

you can't easily provide a test double if its static

[torn heart]

why are you hardcoding numbers

I'm specifically talking about plugin instance

[torn heart]

this is the issue in that scenario that I see

[royal hedge]

hm?

[torn heart]

I mean that this is only an issue if you're hardcoding numbers in the first place

like again I'm still kinda missing a concrete reason for not having just a static plugin instance

like the whole point of statics is they exist once throughout the lifetime of your application

this is something that other things shouldn't really be touching in bukkit in the first place

I read someone mentioning that if you don't do that then it's easier for GC to clean it on reload, but looking at the actual data, that object is usually tiny

[icy shadow]

I think kotlin objects are different though because they’re kind of a separate thing entirely, compared to a singleton class with funky initialisation logic that literally can’t exist in some environments

[torn heart]

kotlin object is in practice just a Singleton

i don't know if their logic is actually different?

[torn heart]

like for example this is independent of whether plugin instance is static or not

[icy shadow]

Ideally you shouldn’t need a plugin instance at all

[icy shadow]

But constructors are almost always better than static access because they make the graph of dependencies much more obvious. Suppose you’re running a unit test on some class which statically accesses the plugin. Your test fails at runtime (maybe not consistently) because the plugin static is null because you’re not running it in a bukkit environment. Compare that to if it was needed in the constructor: clear, obvious, compile-time error because it needs a plugin instance

[torn heart]

this is fair

[torn heart]

well I mean in this case though

the only difference is you waste time testing something incorrectly

cause you're using that instance there either way

but

Ohh

no I see your point

[icy shadow]

again, you should avoid needing a plugin instance as much as possible

In cases where you do need it then you should inject it because then you can mock it etc for testing, or provide a different implementation for different platforms

[torn heart]

I don't get what you mean by "different platforms"

why would plugin instance differ between those

[icy shadow]

Other server platforms

[torn heart]

Ohh

yeah makes more sense

[icy shadow]

You can make one codebase compatible with forge and spigot and bungee and whatever else

[royal hedge]

test doubles as in mocks

or stubs

[torn heart]

yeah

don't have it hard-coded anyway

or just... vary the object that provides those numbers

[torn heart]

this and testing is actually a very compelling reason, you abstract over Bukkit in all your code as well?

cause then this is like

if we're telling people not to use static plugin instances, tell them to abstract over Bukkit as well

[icy shadow]

Yeah you should try to do that too although it’s often harder

Making a fully platform agnostic implementation is a big task don’t get me wrong

It’s not always worth the effort

[icy shadow]

Doing proper inversion of control to avoid referencing a static variable is much simpler than abstracting away all the server logic, so it’s more digestible advice to give

[royal hedge]

1 sec

[torn heart]

yeah but in practice when most people aren't running an external testing suite nor multiple platforms, it's not a hugeee deal

[dusky harness]

Ngl I kinda realized this before but was too lazy to fix it 😭
But maybe now that you mentioned it as well, it's time to fix my habit...

[torn heart]

it's really easy to keep doing forward

cause J's... initialize the constructors

but lwk like

kotlin objects are really cool twin 😭

and having a lateinit field seems sketchy cause it's not enforced by compiler

well technically that's the case anyway

[dusky harness]

I can't remember the last time I used lateinit

[torn heart]

I js have lateinit plugin instance in companion object of main class

I don't actually know why I do that

I don't remember

I don't think JavaPlugin can be object?

[dusky harness]

You could simplify it a bit with JavaPlugin.getPlugin

Or avoid it entirely 🤩

[torn heart]

probably yeah

[dusky harness]

Yeah it can't

[torn heart]

is there a performance cost on this

[dusky harness]

On startup? No

[torn heart]

ah yeah you right

[torn heart]

I wonder if this works consistently in Kotlin object

it should right?

[dusky harness]

Wdym

[torn heart]

in an object can you have like val instance = JavaPlugin.get....

I don't remember when initialization there is exactly

[dusky harness]

getPlugin(Class) is a static method on JavaPlugin

iirc

[dusky harness]

Although you might have to make it lazy

[orchid otter]

What about things like the Logger

[torn heart]

I was thinking this

but actually still like

[dusky harness]

Val instance by lazy { Java Plugin. GetPlugin(My Plugin::Class.java)} ignore formatting I'm on phone

[torn heart]

but there's no difference between this and static

[orchid otter]

If you only need plugin instance for the logger, does it not make sense to make it static

[dusky harness]

Well yeah

[torn heart]

there's still no abstraction

[dusky harness]

It just makes your static code a bit nicer

[torn heart]

it's completely identical

[torn heart]

😭

I disagree at that point

[dusky harness]

That's why I said you could alternatively not use static

[torn heart]

like tbh the only good argument here so far is when you have platform independency

[torn heart]

yeah but what's the difference there still except for what I just mentioned

[torn heart]

like this makes perfect sense to me

[dusky harness]

Difference between the code I put or not using static?

[torn heart]

not using static

I'm not tryna be circular mb J's tryna understand

[dusky harness]

Bm already explained basically what I would say ig (altho I really just quickly skimmed the convo)
And I'm on phone

But I guess it's also about building a good habit for when you do other things other than create plugins

Sure, bukkit makes it kinda unneeded in some ways

But I assume you're going to code on other stuff other than bukkit someday

[torn heart]

latter is actually a very fair point yeah

it's good practice ig

but I'ma still say it's definitely not the biggest sin new devs commit

I remember someone being cautious about putting an if statement in a tick loop cause they thought it was too performance intensive 😭

[dusky harness]

Oh boy
Premature optimization...

[torn heart]

lwk the root of all evil

[icy shadow]

I still think it’s a good habit to get into

[torn heart]

that's fair

[icy shadow]

Even if it doesn’t do MUCH practical difference it teaches you how to do it right

[peak flame]

Does anyone knows ow to achieve this : https://gyazo.com/cb9091db5e8a6542a55c623e05e0aa3c

Hovering over a model gives you this item tool tip and if you click on it you get the gui to buy it

[torn heart]

resourcepack to show tooltip via title text / actionbar / bossbar

raycast to see when player looking at furniture / clicking on it

[tacit timber]

Has anyone ever encountered deluxemenus not registering menus that exist within the gui_menus folder?

for example, i have a menu called "scene_townsfolk_cook_edit.yml", but when i'm in game and type, "/dm open scene_townsfolk_cook_edit", it tells me that the menu does not exist

[weary finch]

Did you register the menu in the config.yml?

[chilly olive]

Does anyone know how I can make my server for usa,europe,asia. I think I need 1usa,1europe,1asia proxies and I need to connect them to my lifesteal server with one domain

[orchid otter]

Why bother? I dont think you will actually get any latency benefit

itll just show better ping in the server browser, but ingame ull still have the ping that comes from the actual paper server

[chilly olive]

I thought it would help because I wanted to be like this server but thanks for the information

https://minecraft-mp.com/server/179012/ping/

[orchid otter]

Well yea ull connect to the proxy faster, but the connection still has to travel to the real server

so it just gives the illusion of better ping

I dont think theres an actual way to reduce ping, cause speed of light, only way to improve ping is to get a better route to the client, you could set up a proxy near the client and hope that ur proxy recieves better routing than the client, but will that be the case, doubt it.

if im wrong id be glad to know

[minor summit]

multiproxy is only really helpful for, like, minigames or skyblock, where you can actually run a proxy and servers in the region, so you'd have minigame/skyblock servers in NA, EU, Asia, and a proxy in each region that connects to their regional servers

anything like a SMP, Factions, Towny, roleplay, where you'd want one server for everyone to share is kinda out of the question unless you want to have different SMP/Factions/etc servers per region as well but that stinks

[orchid otter]

Im not really sure how proxies behave under the hood but ive heard that after the initial connection, you are just connected straight to the actual server and data gets sent directly to it, or do all the packets still get passed thru the proxy?

[minor summit]

no, you are still connected to the proxy

unless you are transferred, but that only works for semi-modern clients, idk when the transfer packet was introduced exactly

neither the transfer packet nor a proxy are a replacement for each other, they are both useful to what they do, and can work in conjunction

[orchid otter]

Fair makes sense

[rare echo]

Hey yall is there a way to set items in the player's inventory using https://github.com/DevNatan/inventory-framework ?

I get an out of bounds error since it tries to set it in the main inventory

[leaden sinew]

Does anyone know the @SuppressWarnings name for Unsubstituted expression warning when using @Pattern?

[dusky harness]

does it not show up in like the quick actions?

[leaden sinew]

No it doesn't

[minor summit]

it should, but alternatively you can @Subst("example string matching pattern") the variable or whatever

[dusty frost]

does the second response help? https://intellij-support.jetbrains.com/hc/en-us/community/posts/206313549-What-Does-PrintFormat-Unsubstituted-expression-Mean

looks like it's a non compile-time constant expression that it can't analyze

[leaden sinew]

Yeah I'm using Adventure Keys and I'm storing / reading the string value which is what causes the issue

I'd rather not turn off the inspection completely, but I also haven't been able to find a name for the suppress warnings

[leaden sinew]

Yeah it just feels weird doing that because it would just be a completely random string lol, but if I have to I'll just do @Subst(suppresswarning")

[dusky harness]

out of curiosity, what's the code that's creating this warning?

since I feel like you should use a valid example value instead of "suppresswarning" 🥲

woah wait @Pattern is pretty cool

didn't know this existed

wait it doesn't work :(

oh nevermind it just doesn't work in kotlin :(

[leaden sinew]

This is an example

public void loadSomeData() {
  String keyString = getStringFromDatabase("some_key");
  Key key = Key.key(keyString);
}

[dusky harness]

ohh

[minor summit]

yeah just slap a @Subst("some_key") on the variable

[royal hedge]

u can suppress any editor warnings like this

or u can disable it from flagging non constant values which is what i did

[sterile hinge]

u r a bad inspection

[royal hedge]

☹️

[sterile hinge]

generally there is a reason why people use the pattern annotation

[royal hedge]

this disables the no @Subst inspection

not the @Pattern inspection

see the option

[sterile hinge]

still it would make more sense to carry over the pattern to the source whenever possible

[leaden sinew]

Oh thank you, I thought that the option appeared on its own, I didn't realize it could be done that way

[leaden sinew]

Yeah it's just nice being able to suppress it in some cases, like loading a string from a database that you know has the correct pattern, but there is no way for the code to know that

[royal hedge]

depends on the context imo

its fine with adventure cuz it @KeyPattern annotations are easy to use

but sometimes its annoying like if its not a parameter

[leaden sinew]

It's also really aggressive about how many warnings it gives, like sometimes it warns on 5 separate lines for one method call

[dense drift]

wasn't there a gradle plugin for paper that allows to start a test server or I remember wrong?

nvm found it https://github.com/jpenilla/run-task/tree/master

Hey, how can I use text colors in deluxemenus config, for displaynames, lore, etc? I want to be able to use any color in hex or rbg or any other format

[river solstice]

probably just minimessage format, like most of the plugins nowadays

[dusky torrent]

Hi, I'd like to know how to buy and sell custom items with Deluxe Menus. Could someone tell me how to do it? Thanks. ^^

[orchid otter]

most of the times ud just take money and use the plugins give command for that item

[dusky torrent]

What I'm really looking for is that some custom items are necessary to be able to execute a teleportation command, for example.

[orchid otter]

you want deluxemenus to create custom items for you?

[dusky torrent]

That you need 3 custom coins to enter a dungeon for example

[dusky torrent]

3 custom coins created with mythicmobs

[orchid otter]

thats a fun one

[dusky torrent]

But I don't know if there is any click requirement in deluxemenus that includes those custom items.

[orchid otter]

You can use the CheckItem-Expansion for a good enough way to check

and i assume u wanna remove the coins too, not really sure how to go about that

[dusky torrent]

Of course, that's exactly what I want

Same as with vanilla items, but they must be custom, if someone could give me an example I would be very grateful. 😊

[orchid otter]

yea not sure, you can try writing a minecraft:clear cmd with the data for those items only

but its all kinda messy

ideally ud have a plugin providing a placeholder for the item amounts and removing

but maybe im wrong

¯_(ツ)_/¯

[dusky torrent]

Well, thanks anyway for responding.

[noble loom]

I've tried that format, its not working tho :/

[wanton terrace]

Does anyone here have experience working with core shaders? I'm currently trying to modify my hotbar away from the vanilla standards

[torn heart]

it's googlable

[ripe gull]

hello

        Bat bat = (Bat) world.spawnEntity(location, EntityType.BAT);

        bat.setAI(false);
        bat.setGlowing(true);
        bat.setInvulnerable(true);
        bat.setPersistent(true);
        bat.setRemoveWhenFarAway(false);

        return bat;
    }``` when i spawn the bat its falling through blocks because its in the "hanging state" how can i make it actually fly in place?

[broken elbow]

I believe there's a setAwake method you can use

[ripe gull]

right im an idiot thanks
XD

[proud pebble]

Currently working on a treecapitator imitation plugin, its working mostly but its giving kinda spotty results of the max amount of blocks its actually broken, currently got what feels like a bandaid fix by double checking the locations to make sure they arent trying to rebreak an already broken location.
basically my code that generates the next blocks to check and then break seems to be giving alot of duplicate coordinates and im not sure if theres something i can do to make it not have those duplicates
i was original using a List<Location> to store the points. switched to a Set<Location> to make the locations not be applied for whats already in the list but it was doing the same thing, so i tried using a Triplet of the x y and z coordinate but it also gave the same result of around 29-32 blocks broken even tho my max block break cap is 35.

https://github.com/lunaiskey/ABP/blob/master/src/main/java/me/lunaiskey/anotherbadplugin/item/tasks/TreeFellerTask.java

mainly wondering if theres a better way to do this or where my code is flawed and giving these duplicate coordinate locations

the idea of my logic is to take a block location, check 1 block around it so 26 possible coordinates, add any coordinates that match that block type to a list, break the original block and then repeat till either it runs out of blocks to check since there isnt enough connected or hits a max block break cap of 35 blocks, tho the max cap is dynamic. i have noticed that theres alot of duplicate blocks being checked and wasnt sure if there was a better way to do it so that it only checks the block's location once

im mainly wanting to filter them just for the fact that it might be laggy to check the block's data for ones that are already air but im probs doing it at such a small scale that its a nonissue

[torn heart]

if you're getting duplicate coordinate locations in a Set, use a record instead of a Triplet

your overall approach is fine

js standard iterative BFS

[torn heart]

i don't know java Triplet specifics tbh but i js suspect they don't override the hashCode() and isEquals() functions properly, record should do that

[ripe gull]

is looping every player every 1 tick and getting values from cache is better than per-player runnable that is every 1tick? like 100 runnables (1 per player) vs 1 runnable that loops all players?

i am making a speedrun timer

the single runnable with player loop is checking if player isSpeedrunning()

the per-player doesnt do that

its cancelled immediately on onFinish

[icy shadow]

1 runnable is likely better

but it depends

[ripe gull]

on?

i just update the actionb ar

[icy shadow]

literally everything, it's the kind of question that isnt really a yes/no answer

java performance is difficult to reason about like that

best thing to do is try both and benchmark

[broken elbow]

Side note, but do you need to update the action bar every tick?

[ripe gull]

Yes, i need to show the miliseconds

smothly

[ripe gull]

            @Override
            public void run() {
                Bukkit.getOnlinePlayers().forEach(player -> {
                    Arena arena = ArenaManager.getArenaByPlayer(player);
                    if(arena != null && arena.isStarted) {
                        long czas = System.currentTimeMillis()-arena.startTime;
                        player.sendActionBar(ChatUtil.fix(getConfig().getString("messages.timerActionbar").replace("{time}", TimeUtil.formatTime(time))));
                        }*/
                    }
                });
            }
        }.runTaskTimer(this, 3L, 2L);```

it looks like that

[icy shadow]

yeah it still depends

[icy shadow]

[proud pebble]

i originally had a List<Locations>, changed it to a Set<Location>, which i thought would stop the duplicates, but it didnt so i tried a Set<Triplet> instead, same thing still had duplicates, i even decided to try manually looping through the set to check for duplicates and still wouldnt get the correct result. so im assuming more then likely its adding to the hashset block locations that no longer have logs in them, which would explain why my check to see if the block is a log or not does actually allow my code to do the full maxblock cap of 35 rather then what it was doing before of 29-32 blocks

also glad to know that im actually be doing it in a good way

ill check out records and see if that stops the duplicates

something else that ive just thought of is that at the end of the loop through the original list of locations, perhaps when im doing getBlock#setType(Material.AIR) its not being processed till the next tick, which means later on if i have multiple block locations having their 1 block radius around them being checked its picking up the blocks that have been queued to change to a different material but havent actually changed yet, another thing that would explain why its having air blocks being picked up since when they were checked they would be a wood log before the next tick which updates them to being air

ill try making another list to check through thatll contain block locations that have been modified already through my code but might not have had their block material updated yet and to skip if that location is the same

Dude Kotlin is already on 2.2.0 and you don't even want to update it to 1.9.0 :')

:(((((

it was supposed to be a quick library update to support 1.21.x

fine, I will do it :((

I feel like kotlin v2 doesn't really have many breaking changes though

[rapid marsh]

hello, the idea of making an homes plugins and a team plugins came to my mind but i don't want to make both in the same .jar i want to make them work one alone of the other but i would love to integrate some stuff of one to the other for example the homes one i want to integrate an item in the gui of the homes that it's the team home how can i make the 2 communicate? (Sorry if it's a stupid question but I'm really new to creating API or whatever can make them communicate)

[dry frigate]

i fixed one thing but its still broken. https://paste.helpch.at/eledowikiw.xml

[dusky harness]

you mistyped github as gethub

[dry frigate]

oh

[dry frigate]

i fixed that but the file is still massive

[dusky harness]

can you send your new pom.xml and also open up your jar file with any unzip program (you might have to rename .jar to .zip first) - what do you see?

[dry frigate]

https://paste.helpch.at/ikusubopob.xml mew pom

https://paste.helpch.at/vifucihila.lua files in jar

[dusky harness]

seems to work fine for me

make sure you're running mvn clean package

if that still doesn't work, try to create a folder and put only the pom.xml in there (that's how I tested it)
then, that should work
you can then slowly add in files until you locate the problem

[dry frigate]

https://github.com/sspacepro/test i created a blank project pasted the pom.xml and it still does not work?

[dusky harness]

https://i.imgur.com/nIT4Hh4.png
this is what I see

but you see all the other files in target/test-1.0.0-Alpha.jar?

from mvn clean package

[dry frigate]

is that the same as running clean in lifecycle?

[dusky harness]

intellij?

[dry frigate]

ya

[dusky harness]

press ctrl twice and type mvn clean package

how big is your jar file

from the test project

[dry frigate]

Ok so not i get that in the target folder do i just always use that instead of the file in the out folder or what do i do with the cleaned file in target

[dusky harness]

no you never use the out folder

[dusky harness]

iirc the original file in the target folder is without any shading

and the other file is with shading - this is the one you want to use

and the out folder I believe is generated by IntelliJ's own build tool instead of maven

[dry frigate]

yo thx your an absolute legend I have been trying to get this to work for days.

[dusky harness]

np
this isn't the first time I've seen this happen, but it's been a while so I didn't think of it - whoops 🥲

If you’re using one of the latest versions you can set the players block break speed attribute to zero and send the block damage packet yourself

Otherwise you do the same thing but instead give the player mining fatigue -1

I have a .sh file I'm running with an intellji configuration, but whenever intellji runs the file it's unable to run java commands, anyone know why?

I'm able to run it fine in terminal

[dusty frost]

bro isn't PATHing correctly

[viscid veldt]

gotta learn somehow

[viscid veldt]

line 1: java command not found

works fine in terminal and normal shell code works but java doesnt work when intellji runs it

[dusty frost]

yeah no it's probably a PATH issue tbh

[viscid veldt]

any suggestions before I google very intensely

[dusty frost]

i mean step 1 would be to just echo $PATH in the beginning of the script

and see what it has

but you might just need to do an absolute path for the java installation

like /usr/bin/javac or whatever

[torn heart]

add java to path

[tame moth]

I'm good :D i wanted to see what fellow devs where up to

[pearl topaz]

oh nice, what one are you working on currently? Or do you prefer to bounce between projects?

[tame moth]

well, im bouncing around between my commission, my open source stuff and the stuff i use for my own network XD

[pearl topaz]

makes sense

[tame moth]

I decided its a good idea to update some of my public plugins as I kinda havnt touched them in a few weeks

[pearl topaz]

i find the things I'm always motivated to work on are the things I want to use

[pearl topaz]

you should give them readmes

[tame moth]

thats why alot of my open source stuff i use for my own network

[pearl topaz]

yep, best source of inspiration

[tame moth]

no idea if i have them or not

[tame moth]

I am the type of person to use very few public plugins and code everything myself for the most part (with my team aswell) there are certain things i will use as im happy with the quality like luckperms for one, fawe worldguard but things like essentials i have fully custom done

[sterile hinge]

I'd be extremely unhappy if I had to touch java 8

[pearl topaz]

it's really not that bad

java 21 feels like java 8 when I've been using C#

[sterile hinge]

[pearl topaz]

someone using something different to you must be very hard to deal with

[tame moth]

java 21 is just better please no java 8 😭

21 is a more fun number than 8 even though i do love 8 im around it too much

[pearl topaz]

21 definitely has nice features

and makes java way better

but the point of EsTools is maximum compatibility

[sterile hinge]

I don't see any point in that, but sounds like a very fun project for you

[tame moth]

Idea

Minimum compatibility plugin

Almost impossible to use

With the users setups

[pearl topaz]

that sounds like something SirYwell would love to make

and then it could get major breaking changes every week

[sterile hinge]

stop talking shit

We generally try to keep compatibility as long as the maintenance burden isn't too high and as long as there are actually people using a version

Otherwise we wouldn't target Java 17/21 :)

Best way to remove "temporary" blocks placed when server restart? (locations are stored in a map)

[river solstice]

loop and remove 🧌

[jagged belfry]

yeah I just remove them in onDisable

[shell moon]

Issue is that when doing that in onDisable as i remember it didnt save it correctly and when forced world save it caused light issues, can you confirm it works as intended?

[shell moon]

#development message

at least last time i tested it was like that

[jagged belfry]

hmm it worked fine the last time I tried. but its been a while so not sure. The only issue with that is if the server force crashes, your onDisable method won't get called.

[torn heart]

just save it to disk continuously and check it again on startup

or have a command for it

[leaden sinew]

What are the temporary blocks? You might be able to get away with just sending the blocks as packets depending on what you need the blocks for.

[river solstice]

something like ixume said, you could save them in a persistent state, such as a file, and then delete them in onEnable instead
this way you avoid it not working when your server crashes too.

[shell moon]

Blocks that players can place and interact with them as real blocks (for minigame like ffa)

[shell moon]

Maybe a yaml file?

[leaden sinew]

If it’s a mini game, you could just not save the world

[shell moon]

It's for a ffa, not an skywars and I was trying to avoid that tbh xd

[minor summit]

I mean, the map is meant to be ephemeral, no? then not saving (or having a template world you copy over and load the copy on each start) is what makes sense the most

[grizzled sundial]

Hi, you can add a command to reset the metadata specific to all players, like the remove command, msi with an all in the player args

Thanks if you think about doing it, I don't have time to modify the source code myself !

Struggling to understand the concept of callbacks with CompletableFutures

I've been reading articles left and right to no avail

for a CompletableFuture "cf1":

cf1.thenApply(fn).thenAccept(csc).thenRun(run)

^ what will that pipeline actually do?

[minor summit]

it's probably better with a more realistic example than just cf1, fn, csc, and run

[torn heart]

you can js ask AI for simple stuff like this

[feral raptor]

I did.

[torn heart]

what is the issue

[feral raptor]

It arguably made me understand it less

lmao

[torn heart]

can't get much simpler 😭

[minor summit]

CompletableFuture.supplyAsync(() -> "oop sucks")
    .thenApply(string -> "wisdom: " + string)         // "oop sucks" -> "wisdom: oop sucks"
    .thenAccept(string -> System.out.println(string)) // prints "wisdom: oop sucks"
    .thenRun(() -> System.out.println("completed"));  // runs and prints "completed"

you are basically "scheduling" tasks for when the future completes with a result, the thenApply will prepend the string "wisdom: " to the resulting string once the first future completes, then it will take that transformed result and print it, once that completes it will run the final runnable

[feral raptor]

I mean this makes sense at a surface level, I just don't get whats actually going on under the hood.

why is each thenX method creating a brand new CompletableFuture, and how is the scheduling actually handled?

[torn heart]

you should just read the docs

[feral raptor]

I would have understood if it was returning the same CompletableFuture and it was just popping a stack post-completion

[torn heart]

hell, read the source code

you'll get a better explanation and deeper understanding than from others telling you

[feral raptor]

I didn't show up here not trying to learn it in advance. I'm coming here to ask after exhausting all options you've already suggested me to do

[torn heart]

not understanding the documentation means you didn't try hard enough to understand it

[feral raptor]

do you have something to contribute or are you just here to ridicule

[minor summit]

to put it bluntly, it just stores your function/runnable/etc in a list of "run after this completes"
it returns a new one because you might be changing the type of the future (e.g. Future<String> to Future<Integer>), for that you need a new object, and so you can attach multiple callbacks to one future without affecting the result others take; if you are performing more work asynchronously then the first future will complete first, but the second future will complete after that other work is done, etc

[torn heart]

I think you're taking a bad approach to learning

[minor summit]

i'd be intrigued if it didn't return a new future

i don't think you're helping

[feral raptor]

thanks for the unsolicited observation, now let me actually respond to/read from the person here whos actually trying to help me

[torn heart]

struggle in learning is fine, and this is something that has abundant resources online about it

and what do you do when it's something more niche and there are fewer resources on whatever you're learning

[minor summit]

do you really think you are being helpful in saying "go read the source code" "you'll get a better explanation than what others are telling you" "you're taking a bad approach at learning"

[torn heart]

I could have been nicer yeah that's my bad

but if the sentiment makes him less likely to ask others for help and instead try to figure it out himself in the future then that's a good thing I think

almost anyone can learn almost anything

in a 1st world country

programming is especially one thing which has an abundance of places to do that

also, if since wanted to know what's under the hood, were you gonna explain the whole pipeline to him?

like this genuinely is the type of thing that is better googled

[minor summit]

if the sentiment makes him less likely to ask others for help [...] then that's a good thing

i...

sure

whatever makes you sleep at night

[torn heart]

I feel like I backed up what I said pretty reasonably 😭

I don't think asking others for help on things that have better resources should be done

yes it can sometimes be more efficient

but as soon as you're asking someone to write paragraphs for you, especially on this, it's likely you'll find a better resource online

like if I asked in chat "how does the network protocol work? like behind the scenes"

[minor summit]

i don't think there's anything wrong with asking someone else with a different wording or a little assistance to help clear things up

[feral raptor]

how did you conclude that I didn't try to figure it out myself first? Why did you immediately assume that I did no due dilligence before asking here?

Also, by your logic this channel is pointless and should be closed

[torn heart]

are you not understanding something with the methodology of how completable futures are architected? or with how asynchronous tasks are done in general?

I feel like your initial question was unclear

[torn heart]

don't strawman me 😭

I think there's lots of things that are really useful to ask about, often because they are quite domain specific and have less information online

but also a lot of the questions here shouldn't be asked yeah

lots of people simply don't google

there was a conversation here about static plugin references and I learned a good bit there, that was a good discussion for example because it was more complex and domain specific

[feral raptor]

thats one way to look at things -- "it was useful to me so its relevant"

[torn heart]

I don't think youre evil or stupid or something for asking the question

[torn heart]

man

I'm like genuinely trying here

you strawmanning me so hard 😭

[torn heart]

😭

[torn heart]

you never even answered this either

genuinely asking

[feral raptor]

I think I get what you mean--what I understood when I read an article this morning was that this "list" structure works by every "Completion" instance containing a reference to the future before it (or after it)

So basically, cf1 finishes executing and runs postComplete which will then invoke its Completion instance, which in turn invokes its associated future which in turn invokes its completion instance etc etc.

So basically what happens is when you do thenX on an existing future, and assume the initial task has finished already:

• you are setting its Completion field to be a new Completion (lets call it thenCompute) which actually has a new CompletableFuture as state

• it then calls postComplete() which will then invoke the Completion instance which will invoke its attached future (either inline or async). This attached future can also have a Completion instance that it invokes etc etc

[tight junco]

I'll bite actually, It's incredibly dismissive and unhelpful when someone comes to a place for questions and support, to tell them to go elsewhere and find the support all by themselves and just a worthless contribution, I don't think they're asking for the whole declaration of independence to be explained but if someone can spare the time to explain something in a way someone else is actually able to/more effectively understand, there's no actual issue there

If you really want to push for self sufficient research, give them a vague explanation and provide links to sources for them to research in case they haven't, while also answering the question, even if vague (#development message this wasn't very complicated or longwinded of an explanation and neither was this #development message), Pushing someone away from actually receiving help has a significant longrunning negative impact

300 people a day would come in here asking how to make commands or do whatever with plugins, the solution was never to just tell them to learn java and come back later, It was always give them the answer, while also giving them resources to look into it more

Personally, I can write stuff all day, do circles on people but if i have to sit and read lengthy, in depth documentation, i literally cannot do it, i do not absorb any of the information at all. In reality, You don't know any of the people who are asking for help, nor the ways they learn things the best. Sitting at your chair with drool down your face, crusted on the desk, reading books and source code might work for you. It doesn't work for everybody else

https://tenor.com/view/lick-tongue-out-white-cute-gif-18364172895364882269

[feral raptor]

Going back to the CompletableFuture (CF) topic, what I currently understand is that callbacks will actually instantiate and assign a Completion object as a field of the CF instance. After the CF finishes its execution, it calls CF#postComplete which will in turn invoke Completion#tryFire(SYNC/ASYNC), which will in turn invoke that Completion's own CF (for simplicity, lets just go with a synchronous callback).

The aforementioned event will repeat recursively.

[tame moth]

crazy

i didnt know about it XD

now in it XD

[torn heart]

you're right I should have provided an article or resource instead of being that dismissive

[torn heart]

i find this to be a changeable thing for people, learning styles, but I get how it's difficult

I don't know if I necessarily agree with "pushing away people from getting help has a long running negative impact" in a field like programming specifically

it's definitely a negative in some circumstances

but I am trying to push for self sufficiency

though I understand why I didn't do that well above

[torn heart]

my point was kinda that this thing right here was not hard to clean by just looking at the implement in code

like genuinely not trying to be condescending, but in this case his question seemed to be like directly answered by just looking at the implementation, and not even necessitating anything deep

I agree I was rude and unamicable, but I genuinely feel like this was the simplest way for him to get his question answered

if I'm wrong please tell me how

like if your question can be answered by looking at a (simple, which is true here) function implementation, is it wrong of me to say that you should do that before asking other people?

[icy shadow]

Controversial take but I think trying to make an understanding of the implementation to understand the high levels is not very helpful

Just like the stream api, it’s designed in a way that you don’t need to understand the implementations

You’re more or less correct but I’m not sure if it’s helping your understanding of the type as a whole

[torn heart]

I agree w this ^

unless you're performance maxxing, you don't usually need to know these specifics

[leaden sinew]

I like to minimize my performance

[torpid raft]

i like to maximize my minimizing

[feral raptor]

I get what you mean -- I just have this pedantic thing where I want to at least know how it broadly works before I use it. I know enough about how the stream api works under the hood such that I can dismiss the full intrinsics of it

I just don't want it to feel like magic per se. Like when I was studying reflection, I just needed to know the general idea of how it works, that is, that it uses JVM intrinsics to pull data about classes from the metaspace at runtime--I don't actually need to know how it does it exactly, but having an understanding of it helps in ensuring that I'm not just applying mindless libraries with no understanding

[graceful hedge]

I think that depends very much on the library, some libraries are easier to just apply in a brain-dead fashion, whilst other libraries require more profound knowledge.

[hexed crag]

good day everyone, if someone includes the deluxmenus plugin once, please help, I need to hide on the leather bib *painted, I use nbt_int: 'HideFlags:63' for this, but then Hide_attributes: true disappears. also with potion, help, hide it effect

If I wrote in the wrong chat, I apologize.

[tight junco]

heyyyyy #general-plugins

[feral raptor]

I feel like I have to "earn" the privilege of applying libraries mindlessly. If I can't at least to a degree implement the code im leveraging, then how am I learning to be a better programmer at all?

[graceful hedge]

I mean yea thats fair and ofc it depends on how exactly u see the term better, i think a problem with being pedantic about knowing+understanding everything is that it can at times compromise on for example productivity

[pulsar ferry]

Why?

[torn heart]

null checks were slowing down part of my code by 50%

I could have rewritten that (and eventually I'm going to, not for this reason but for performance) but physics engine is intensive, so release builds should avoid any sort of unnecessary safeties, as those can be checked in debug builds along with other invariant checking

also Kotlin coroutines are actually so awesome

they're ~10% more performant on my machine than fixed thread pool for CPU bound tasks

Hello everyone, please advise best way to use MiniMessage#deserialize with placeholders in a string. Does parsing Component each time to insert placeholders create unnecessary load? Is it better to use TextReplacementConfig, or can I just use MiniMessage#deserialize? Thank for answer

[minor summit]

using mm each time is fine

unless you are parsing tens of thousands of components every second or something ridiculous

[torn heart]

you can minimize performance cost by just checking if previous string is equal to current string

very simple optimization that will probably cover you

if you have repetitive rapidly swapping states you could technically cache it but like

[torn heart]

remember to benchmark if you're unsure!

[tame moth]

I need some feature suggestions. Im making an alternative to tebex, its already gonna be 50% cheaper any features people would want to see included

[long raptor]

Thanks for answer!
I heard that replacing will be faster than parsing, that's just why I wanted to ask about it

[torn heart]

test it out :)

[minor summit]

well, you'd also need to keep track of placeholders, which if you are doing anything mildly dynamic (such as piping PAPI through MiniMessage) is not all that feasible

[torn heart]

I was assuming their usecase is something like text -> papi -> MM, so I was saying to only regenerate MM if previous output from papi is different from current

I may have misunderstood though

[minor summit]

i was thinking a minimessage string containing a <papi:foo_bar> tag

[torn heart]

ah ic

I lied. It depends. As always.

the updateGameObjects and the removedGameObjects are where update or remove call end up in. does these two list thread save enough for me to do a copy and clear when i run update or do i need to use synchronized list ?

[torn heart]

are you sure you need the game objects as a list

queues are much better for concurrency

[torn heart]

since you're talking about rendering i'm assuming you're having gameobjects be updated from outside of this thread. for this the easiest thing is to have the gameobjects list be private and have a "queueRemove(GameObject go)" and "queueAdd(GameObject go)" or something of the sort which adds to a threadsafe structure like a ConcurrentLinkedQueue, and then in your render loop you can iterate through it at the start/end of your tick

you want these queues separated from your main object list because you don't want objects to be added or removed during stepping

also CopyOnWriteArrayList is probably the best concurrent list implementation IF you NEED to use a list in a game context since its doubtful you have elements moving in and out more than youre reading them. but prefer Queues because they are an inherently better data structure for concurrency (the "index" nature of lists make them unreliable for concurrency)

[neon pewter]

the queue list is updated via method call so the problem im worry is that when the batch update started some object might be send to remove need update or addition , which will affect the live list the the renderer is iterating over

[torn heart]

avoid having anything outside of that class accessing the queue

it's fine if an object is added to one of the queues while it's being iterated over - that's the safety with concurrent structures

[torn heart]

however you do need to make sure that in the queueRemove and queueAdd methods here, that the objects are obtained and cleared from that queue atomically

otherwise they might not get removed / added

something like this (getAndClear must be atomic)

    private fun processToRemove() {
        val ss = bodiesToRemove.getAndClear()
        for (body in ss) {
            kill(body)
        }
    }

i don't know 100% if this is the best implementation but i have never had any issues with it and it works, i just use an AtomicReference<List<T>> in my physics engine

so i can write stuff like this very easily

    fun getAndClear(): List<T> {
        return items.getAndSet(emptyList())
    }

w full safety

[neon pewter]

well im currently doing this:

    public void queueObjectForAddition(GameObject go) {
        queueObjectForUpdate(go);
    }

    // Add a game object to the removal list and remove it from the update list.
    public void queueObjectForRemoval(GameObject go) {
        updatedGameObjects.remove(go);
        if (!removedGameObjects.contains(go)) removedGameObjects.add(go);
    }

    public void queueObjectForUpdate(GameObject go) {
        if (!updatedGameObjects.contains(go) && !removedGameObjects.contains(go)) updatedGameObjects.add(go);
    }

    private void addGameObject(GameObject go) {
        List<SpriteRenderer> sps = go.getComponents(SpriteRenderer.class);
        for (SpriteRenderer sprite : sps) {
            addSprite(sprite);
        }

        List<TextRenderer> ts = go.getComponents(TextRenderer.class);
        for (TextRenderer txt : ts) {
            addText(txt);
        }
    }

the renderer doesnt care about the object itself, it end goal is to extract renderable component out of the object.

[torn heart]

if you wanted full thread safety, queueObjectForUpdate isn't technically safe because those lists could get modified between the if statement and updatedGameObjects.add(go), you need to either synchronize or make it atomic

w concurrent stuff you have to remember that you cannot ever trust the state of something between 2 statements without some other guarantee

[neon pewter]

i could minimize the risk by limit where the logic server can access the renderer call right ? Currently object add remove or update operation on the logic thread is queue into the scene, the scene collect the queue then process it at the end of each loop cycle. So for now the the access is sequential so it should be ok?

[torn heart]

if you don't have different threads accessing it concurrently then it's safe yeah, I don't exactly I understand your architecture so I can't give a very detailed answer

[neon pewter]

i use server system, where a task like logic and renderer task is assigned a thread for the engine's entire runtime

[torn heart]

if they're on different threads you have to synchronize/atomic in places like this

the risk is you randomly don't have objects added into the scene

or removed

or whatever the thread does

if you're not modifying the list a crazy bunch and want smth simple just use AtomicReference

https://github.com/Ruskei/Udar/blob/main/src/main/kotlin/com/ixume/udar/AtomicList.kt

no synchronization needed and perfectly safe

& very easy to implement

[neon pewter]

i'm glad that the scene is a logic thing

[river solstice]

why so many collections

I am sure it does the job but it looks like a fragile design to me

[minor summit]

what do you know about fragile design anyway

[sterile hinge]

uuid = string is more concerning tbh

[worn jasper]

tbf I wonder how unoptimized Runway is lol... I convert components to string, replace text, parse PAPI (maybe) and convert to MM again lmao

and that being for each component

for each packet

[river solstice]

nothing 🐸

[torn heart]

root, added, removed, are 100% necessary, first one is necessary (though it should be UUID, not Strong)

last 2 I'm not sure but seems reasonable

other than it being String

if all of them are managed in a few methods w high locality of behavior it's pretty fine

[river solstice]

well, I don't know the whole context and how are they used, so it's difficult to tell

[torn heart]

concurrent rendering

so you need those extra queues for processing either way

[neon pewter]

why it is concerning ?

the uuid is actually stored as string for the object

the value is generated and converted to string when the object first created and it is serialized when save and on load

[sterile hinge]

yeah but why

stringly typed is generally a bad sign

[neon pewter]

i don't see why it is a bad sign right now could you explain?

[neon pewter]

2 added and removed queue are essential, the root collection is for quick access (so you don't have to filter and stream everytime), and the component collection is for path access (similar to the $CollisionShape2D thing you can do in gdscript)

[sterile hinge]

Why aren’t you using UUID?

[icy shadow]

componentsByUUID.put(“not a uuid”)

[neon pewter]

if the component carry a uuid that is not a uuid, wouldnt the system use the malformed uuid to get the component with malformed uuid ?

[icy shadow]

it’s still a bad practice to allow malformed ids in the first place

Also using UUID will be faster because it has a much more simple hash function

[neon pewter]

i see, thanks for clarify that

[river solstice]

public class MyCoolUUID {
    private final String original;
    private final UUID uuid;

    public MyCoolUUID(String possiblyMalformedUuid) {
        this.original = possiblyMalformedUuid;

        UUID parsed;
        try {
            parsed = UUID.fromString(possiblyMalformedUuid);
        } catch (IllegalArgumentException e) {
            // Oops
            String sanitized = sanitize(possiblyMalformedUuid);
            try {
                parsed = UUID.fromString(sanitized);
            } catch (Exception ex) {
                // Whatever lol
                parsed = UUID.randomUUID();
            }
        }
        this.uuid = parsed;
    }

    private static String sanitize(String s) {
        // Force it into the "8-4-4-4-12" UUID format B)
        String hexOnly = s.replaceAll("[^0-9a-fA-F]", "");
        hexOnly = (hexOnly + "00000000000000000000000000000000").substring(0, 32);
        return hexOnly.replaceFirst(
            "(\\p{XDigit}{8})(\\p{XDigit}{4})(\\p{XDigit}{4})(\\p{XDigit}{4})(\\p{XDigit}{12})",
            "$1-$2-$3-$4-$5"
        );
    }
}

[sterile hinge]

💀

[dense drift]

I would not use the string unless the id is exposed to an user (config, database, commands) tbh

[tame moth]

i just made a discord bot that uses ai to read your promt and sets up an entire discord server roles channels catagories ect for you in 5 seconds

[neon pewter]

well i do need to serialize that to a file with gson....

[dusky harness]

gson supports UUIDs

it will automatically run UUID#toString and UUID.fromString() for you

[dusty frost]

i was gonna say bro, any serialization framework will do that for you

SQL libraries serialize it to/from bytes if your SQL server supports it

[dusky harness]

not kotlinx.serialization 😐

recently found https://github.com/sksamuel/hoplite tho which looks nice

[dusty frost]

yeah i'm the #1 Hoplite lover bro lol

[dusty frost]

to be fair, I think they now automatically support the Kotlin-native UUID

they just couldn't do the JVM UUID for multiplatform reasons

[dusky harness]

ah

oh that makes more sense now

[dusky harness]

making up half of hoplite mentions in this server 🙃

[dusty frost]

on god bro

that shit is peem

[dusky harness]

I guess making a jvm specific module for just serializers would be a bit overkill

[neon pewter]

oh it does? the more you know i guess

[minor summit]

you mean the opt-in experimental Uuid?

like bruh it's just two u64 how hard can it be

[pulsar ferry]

Which isn't serializable by default either
As for why it's experimental, basically any Kotlin feature has to be experimental for a few releases before it's marked as stable even if it is as simple as a class :')

Ah wait quick update on that, it's not @Serializable but it is internally serializable by kotlinx.serialization, i guess it makes sense

[worn jasper]

imagine not using polaris smh

[pulsar ferry]

Do you use it? lol

[worn jasper]

I used it in some past plugin I had done

kinda like it

[pulsar ferry]

Oh interesting

[worn jasper]

I am gonna rewrite Runway, still checking what I will use

since I technically do have my own config system xD

but might go with yours as it is probably much better/safer than mine

I don't trust myself xd

I also need to see how in the world I am gonna optimize runway's parser

I have no idea how I will do it... caching? idk

I never did benchmarks in the current way, but I'd assume it sucks at performance in bigger servers

[snow grove]

oo this kinda cool

[worn jasper]

https://github.com/xMrAfonso/Runway/blob/master/src/main/java/me/mrafonso/runway/util/ProcessHandler.java#L56 this does not look pretty xd

[snow grove]

meowza

[worn jasper]

?

[snow grove]

idk

[minor summit]

setting config values :(

[worn jasper]

don't question it

that's the least of my worries

[unkempt kiln]

Hi guys, am I able to ask for help regarding java stuff here or just MC specific?

[dusky harness]

yeah java stuff works too

[unkempt kiln]

Regarding constructors and Inheritance, if I have a constructor in a subclass am I able to use a this statement in a constructor and a super() in the next constructor?

[river solstice]

If I understood your question correctly, this is allowed, for ex.:

class Parent {
    Parent() {
        // Parent constr
    }
    Parent(String msg) {
        // Parent constr with args
    }
}

class Child extends Parent {
    Child() {
        this("Child without args");
    }
    Child(String args) {
        super(args); // super();
        // Child with args
    }
}

[unkempt kiln]

hmm i see

[worn jasper]

actually, I have never seen "this" being used like that

[river solstice]

that's just constructor overloading/chaining

similarly

public void methodWithoutArgs() {
   methodWithArgs("Hello");
}

public void methodWithArgs(String arg) {
  // ...
}
