[young knoll]

The server also does that

[timid berry]

sure things the player can see that move more then 20 ticks in a sec will be bugged

yes

but

why did the spigot authors

continue?

wouldnt the server be more efficent

[young knoll]

Why would they not?

[timid berry]

if it was higher?

games llike csgo use 64

ticks

[young knoll]

Sure, if the server could magically handle that

[timid berry]

well

its not like

we cant modify it

[young knoll]

Sometimes hitting 20 is a struggle

Of course now we have the /tick command anyway

[timid berry]

oh yahn

[mortal vortex]

Because CSGO isn't procedurally generated, with multiple chunks being rendered concurrently.

[remote swallow]

To properly have a higher tick rate you have to modify a lot, path finding is tick based and a lot more

[timid berry]

is the way of making configs in bungee the same as

spigot?

[young knoll]

Hey it still works at higher tick rates

They just go zoom

[mortal vortex]

Based on the amount of questions you're asking, I'm assuming you haven't properly read the docs?

In BungeeCord, you use net.md_5.bungee.config.Configuration and net.md_5.bungee.config.ConfigurationProvider instead of Bukkit's FileConfiguration.

[timid berry]

chat how do i make sure i can get the player count without it error when trying to get it from turned off servers?

[timid berry]

u right

[eternal oxide]

a "turned off server" will have no players

[timid berry]

will it show errors tho?

when it tries to get the size of a

turned off spigot server?

[eternal oxide]

I'm guessing you are getting an NPE?

[young knoll]

Presumably it just won’t be in getServers()

[mortal vortex]

Yeah, getServers() returns all the connected Servers. It simply won't have an entry if it's offline.

[timid berry]

Object apiurl = ConfigurationProvider.getProvider(YamlConfiguration.class).load("config.yml").get("apiurl");

is this how i

get values from the config

and set as variables?

[mortal vortex]

um

no.

[timid berry]

i see

how i feel when pressing tab on idea does not make things work

[mortal vortex]

Here I'll dm you what I normally use. Just like the Config Util class I setup.

[timid berry]

okay!

[mortal vortex]

Look over it. It'll help

But tbh I haven't used bungeecord in ages. Other than that I can't help much

[mortal hare]

so i've just started thinking about relational databases lately and im very stuck on the idea of putting business logic on the database, basically creating headless application of your logic on the database with procedures triggers using SQL.

Here's my point on this:

• Sure this could induce vendor-lock in, but knowing that there's plenty of good relational open source database servers, i dont think that's an issue anymore.
• You and your business wouldnt need to reinvent the wheel in the long run, when you want to migrate your app to some kind of other technology like moving from Laravel to Java and backforth, as if you write standard SQL procedures and triggers, you can make cross compatible code between SQL databases. Also SQL code from 20 years ago would work just fine in today's world.
• You eliminate the latency of multiple SQL statements to access the same data for calculations within the client. Its just more performant overall
• Its not as if your project doesnt utilize the database technology anyways, so why not embrace it?

What do you guys think? I personally now then i think about it i adore the idea of creating headless low level version of business logic application in the database and leaving the clients to build the best user experience around it, acting like thin clients around low level database logic.

well unless your computation is very very expensive to compute on the database server i dont see a reason, to not compute it. Its not as if big corporations run all the database operations from one big dedicated server. they use bunch of caching technologies and CDN's to deliver to the clients, thus you can scale the SQL code from cache databases too.

In that case, I think tying business logic with particular protocols which are open to the public use is kinda bad (like HTTP, since it still has to follow MVC approach to handle business logic). Isolating logic as much as you can from external technologies in a way of blackbox design which computes the results you want from a database and then spits back to the technology you want to open to the public, like an API sounds like a good approach.

[warm mica]

You are suggesting to turn a sql into a http server?

I'm not really sure what you are suggesting, but graphql is probably what you are looking for

[mortal hare]

not really. Im proposing an idea to to move as much of business logic from technologies which open your business logic to the public (like http servers)

SQL servers is just one of the solutions for this as most of the applications rely on them anyways and they can be pretty scalable and maintainable to run at least.

using SQL server for your business data logic handling or general purpose language with low level interface to get the computed results from database seems to me the most robust approach for handling maintainability in the long end, since you wouldnt need to touch business logic code if protocol related stuff changes, you would maintain only the glue code between your business logic black box application and the technologies which you are using for UX

another way of thinking is that you should treat your business logic as as a shared object (.so) or dynamic linked library (.dll) file within your project

you use that .dll in the glue code that invoke that particular logic wherever you want (HTTP services, RPC, etc)

[wet breach]

What you are wanting is a custom sql client

Which is a thing

[mortal hare]

we have procedures and triggers, which are basically more than enough for basic business needs

[wet breach]

Right but you still need something to allow communication. Its not like you can just connect to the database directly and it start doing things like front end. A sql client could show front end and simultaneously be directly connected ie logged in to the db server.

[mortal hare]

well yeah, what you referring as a "sql client" i was refering as a glue code in whatever technology you want, it doesnt need to be particularly web based tho

you develop thin clients around headless SQL application

[wet breach]

Otherwise your alternative is restful api's

But amazon aws is basically your calling though

What you describe is basically what it tries to do and provide lol

[mortal hare]

i just dont kind of get it why people use SQL servers only for storage and data integrity, its just wasteful

SQL can do procedural programming in itself

[wet breach]

Because at its core that is the purpose of things like mysql

[mortal hare]

so why bother introducing latency with multiple requests

when you can develop couple triggers and procedures

and store the business logic there

and most importantly you implicitly ensure the data integrity from outside factors too, you wouldnt need to rely on separate application to input the data properly most of the time

[wet breach]

Well it depends how well you know what you are working with. Mysql supports unix sockets and literally can handle millions of queries with just a few hundred megs of ram

There is virtually no latency with unix sockets

[summer scroll]

Hey guys, need a little help here. I'm developing a hunger game minigame plugin and I wanted to glow teammates only, but I encounter a problem where everytime player's metadata got updated (changing running state, sneaking state, etc.) the glow got removed and I found a way to reapply the glow by simply listening to those events, but it doesn't feel smooth at all because of the flickering, what would be the best approach to this to avoid the flickering issue?

[echo basalt]

packet interception

Here's a very old example of how to do so: https://paste.md-5.net/ruyetifure.cs

Might not work due to async entity getting but whatev

[mortal hare]

its more of a maintainability part that gets me. SQL syntax has been stable for a while now. You can run 10-15yr old SQL on multiple DB's and get the same result, as long as its standard SQL syntax.

If you have custom sql client which then gets used within multiple technologies that fine, as long as you wouldnt access database externally.

but i just dont get why would you write code in Web based technologies like PHP or JavaScript with bunch of libraries which tend to break quite constantly as web technologies improves at rapid pace. Its not as if your business code should tell what HTTP status code return. Its your custom sql client's responsibility to do that, not your business logic application's.

[summer scroll]

Thank you. I'm using packetevents, but I kinda get the idea.

[mortal hare]

Separation of concerns should be applied in such cases. "Glue code" for bridging the gap between HTTP server and your business logic should be developed as separate packages

[echo basalt]

I feel like the vendor lock-in problem is mostly applicable here. I write my code to support as many database types as possible because realistically some are more fit as a solution than others

Switching from SQL -> Mongo should be as painless as possible

As something like MySQL -> Postgres -> Planetscale would

[mortal hare]

well in that case, yes, but developing a custom headless client could be still beneficial to isolate most of the logic that's needed for the application to function at bare minimum

[echo basalt]

SQL is made to operate as a persistent storage server. Making your SQL server do most of your business logic introduces strain in the database that could be shifted to the application. Scaling your application consumes a different ratio of resources than scaling SQL

For example if your operations rely on processing a lot of data you'll probably allocate more compute power to your application and at a large scale you might run your application on purpose-built boxes with that in mind

Where you might, for example. use a small HDD / Flash drive and keep everything in memory

Attempting to scale SQL like that can cause issues as you need more compute but you're building for storage

[mortal hare]

yes i get that, but some people just straight up tie-in their apps with web technologies instead of totally isolating the code that could just work in "headless" mode in the first place

[echo basalt]

Microservices

You get to scale the parts of your application that need to be scaled with the hardware they need and the database acts as a database with no vendor lock-in

[mortal hare]

well yeah, if they don't get vendor locked-in from the application logic part

[echo basalt]

You can then run them on whatever cloud provider you want

[mortal hare]

with certain frameworks or libraries

[echo basalt]

You can easily switch database types as long as your code isn't complete garbage and you get pretty much no latency if you run the database in the same datacenter as the microservice

Private bandwidth is pretty much unlimited and latency is astronomically low

Price is slightly steep but not as steep as serverless and you can turn it up and down based on demand

[wet breach]

Idk what bunch of libraries you are referring to for php since there is really only one library for mysql in php which is a native component. For javascript there might be more libraries but this is because javascript was never intended or designed to run backend rather front end so there isnt really a standard for such things.

[umbral ridge]

Hi frostalf

[echo basalt]

hi frosty imma order lego

[wet breach]

While sql may support what you are talking about you are forgetting you need to have something designed for the things you are talking about. mysql for example is something made already and is well known and works quite well for what it was designed to do. To make somethin like what you are talking about you either need to find it or make it and making it might seem easy but maybe not if scaling is a concern or optimizations etc

[mortal hare]

i think stating sql in this convo is a mistake here since i dont think that's the point here really is. The point is that i wanted to make its seems pretty reasonable in the long end to make your business logic as an application which acts like a blackbox and develop custom clients for it to suffice for different cases you need, if you need to expose it under web technologies, develop a client for HTTP server with custom routes, need RPC, develop a client for it etc

the main point i'm trying to make is that your business logic code part shouldnt depend on the protocols you have no control of

and only the "glue code" part should be maintained

[echo basalt]

I feel like your business logic should rely on standard protocols, not proprietary ones

[wet breach]

And which protocols do you not have control over?

[echo basalt]

You get the benefit of being able to hire people that don't want to immediately rewrite your entire project

You also don't have control over the database implementation you're using, do you?

[wet breach]

I guess what you are asking is why people dont develop custom servers or applications? Answer to that is time and money.

[echo basalt]

Make sure to optimize for engineering time and money $$

Hiring engineers to maintain your proprietary mess is gonna cost more than to run it the traditional way

[wet breach]

Or take a lot more time

[mortal hare]

lets say i've written my business using HTTP server technologies like PHP, and now business wants to use that logic on some kind of thing which completely doesnt need HTTP protocol, and now that thing needs to depend on http protocol to properly run that business code. Now you need to rewrite your code in something else or make a wrapper around that application which is really a workaround around a problem which wouldnt have existed if you separated your code from the protocol itself

[wet breach]

Depends on the protocol. Php is protocol agnostic

That it is, it does not rely on a protocol to operate

[mortal hare]

well kind of, but its web oriented

you usually run php with Laravel which uses MVC design but fair point

[wet breach]

I dont use laravel

If laravel is the limiting factor then it would be that framework at fault not php itself

But i dont use frameworks with php exception being maybe bootstrap as i dont like making auth myself

I have used php for ssh and other protocols. It just depends what it is you want it to do and php can serve content over those protocols as well not just obtain data.

But it also depends on the server you are using to serve php too

But then we get into other things that can sudo replace a web server entirely

Like routers

Routers can do a lot with protocols as long as you program the protocol into the router which is not difficult. I have done it with mc and you can let the router handle what to do with the packets directly

So i have used a router to basically be a bungee without bungee

But you would never know the difference lol

Since php has a cli and is not entirely dependent on a web server you could just remove the web server entirely if it doesnt serve your purpose with whatever you are doing with php

[mortal hare]

php is just a bad example my bad, it can stand at its own thing, but when you add frameworks to your code and tie in HTTP request controllers, middleware with your serverside business logic, like laravel or with next.js framework, it gets messy. that's what im trying to prove

unless you expose your framework app as a http service in such cases, you cant do much

you just cant run such applications in "headless, standalone mode" thats independent from http

i meant it just a compromise over dev speed

but it backfires in the long end

[wet breach]

Ok, well i wont disagree with that last point but most of that stuff is unnecessary and are used because that is what someone with php knowledge only would know how to use and setup. Reason why system admin is a job title and even specific courses in school to learn how to do lol

Reason not everyone goes the router protocol route is because not everyone has control over the firewall and even if you do you need a person who is knowledgeable in networking. So you have other stuff that gets used instead. Mainly because of limitations lol

[mortal hare]

it might sound like conspiracy but i believe why there's frameworks like these is kind of a planned obsolesence from the companies who use such flashy tech which design the products so that they can milk the money out of the customers for the maintenance of the product

[wet breach]

Well it isnt a conspiracy that they want to lock in customers to their tech. However there is another side to it which involves contracts

Most companies cant offer support for stuff that isnt theirs or if they do its limited support

Its not a good business practice to offer guarantees if the guarantee is on something you dont make or have control over the final product of it

So you end up with frameworks that are company specific. But then you also have the free market trying to make it easier on the developer so you end up with more and other frameworks lol

[granite pasture]

Hey! I'm trying to make an ArmorStand look at player, so I used setRotation but seems that the pitch is ignored, yaw works good. Also I used setHeadPose and that worked perfectly, I don't want to use setHeadPose because I want that the position of the entire ArmorStand to look at the player. I'm using Spigot 1.21. Pitch is really important to me.

[mortal hare]

i believe using frameworks for business logic is just bad overall, isolating it as much as you can from frameworks and only using frameworks or protocols for glue code should be really ideal. Unless your trying to push product to the consumer fast or the product should be mediocre at best, in the long term you would spend more time maintaining the business logic due to changes in the framework. Isolating it from the UX part could save lots of time updating the app to be deployed properly, due to how much less code would be touched, since only the glue code would only need to be fixed

im repeating myself, but i get your points

imho things like a next.js or laravel might work for short-time, but after a while you get constant need to update your codebase to be compatible with the latest framework versions

it becomes a burden where it shouldnt if you separated the logic from the framework itself and left only the code thats reponsible for bridging the gap between the app and the framework

[earnest girder]

Is it possible to update an item’s meta (lore & custom data container specifically) without causing the item update animation when a player is holding it?

[mortal vortex]

I've seen it done with NMS

But without NMS, I do not believe it to bbe possible

[summer scroll]

Is there an api to check if the block can be stripped using axes?

[blazing ocean]

There might be a tag for that

[echo basalt]

🤔 applying a translation to a text display causes it to just disappear.. hm

[blazing ocean]

What's the translation?

and are you sure you're setting it as a translation and not rotation/scale?

[echo basalt]

pretty sure I am yeah

0, 2, 0

[blazing ocean]

are these numbers from wiki.vg?

[echo basalt]

Yes

[blazing ocean]

what version?

[echo basalt]

and from https://gitlab.bixilon.de/bixilon/pixlyzer-data

1.21.1

[blazing ocean]

they're outdated

oh hm

[echo basalt]

23 works fine

if everything's shifted it'd break

Best I can do is use reflection to fetch the display entity data synchronizer and use it to create the value

feels like overkill

[blazing ocean]

does it show up in f3+b?

[echo basalt]

zero hitbox, pretty sure it doesn't

might be worth spamming more packets

I do send add entity / name packets like every second

[blazing ocean]

i mean it's what I do ```kt
DataTracker.SerializedEntry(
DisplayEntityAccessor.getScale().id,
TrackedDataHandlerRegistry.VECTOR_3F,
Vector3f(0.1f, 0.1f, 0.1f)
),

or, mixins at least

I'd probably try that just to be sure tho

[echo basalt]

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

what I got rn

[blazing ocean]

also, why not just use the API for this? hideByDefault or sth

[echo basalt]

Need these do be per-player

and that's a lot of entities to manage with bukkit

which can cause world leaks if I'm not handling it with care

and lots of setPersistent(false) calls

chunk saving etc

cba

hm, seems like my customer found an error that's completely unrelated

I'll take that ig

[summer scroll]

Guys, how can I make the player's name to follow the color from the prefix?
I'm using scoreboard team.

[lilac dagger]

ChatColor.getLastColor

altho it doesn't support hex

there's getDisplayName but i couldn't get it working

ohh

you need team.setColor

[summer scroll]

Like where can I put that? it's separated between prefix, display name, and suffix.

ohhh

Damn that will definitely break something on my plugin because of how I set it up xd.

How does plugin like TAB modify that, the player name can be bold or whatever?

I think this one? https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#setPlayerListName(java.lang.String)

[lilac dagger]

i'm not sure if you can have it both bold and colored now

sure, but this won't edit it above the player

[summer scroll]

This one maybe? https://hub.spigotmc.org/javadocs/spigot/org/bukkit/scoreboard/Team.html#setDisplayName(java.lang.String)

[lilac dagger]

i'm not entirely sure how tab does it

i think it might be set display name but it didn't work for me int he scoreboard

[summer scroll]

You're right, setting it with Player#setPlayerListName will not set it on the nametag.

[lilac dagger]

i think tab is open source no?

i think they use nms not sure

[summer scroll]

Yeah either packets or nms.

[lilac dagger]

both are nms

the color being reset is only a bukkit thing

i have this code that changes the player name

[summer scroll]

So the only way to done this is through nms?

[lilac dagger]

i guess so

you can learn from tab

maybe the developer found a way around this

[lilac dagger]

is it normal for Player#getCompassTarget to return null during player join?

even tho the method is marked as non null?

[summer scroll]

You can try to add a delay

[lilac dagger]

i just skip it if it's null right now

the delay is not worth it, causes some other problem

[summer scroll]

even a tick?

[lilac dagger]

yup

i have a method that does some thing when the party leader joins

it is also an issue that on join i don't have direct access to this method to delay it only

it'll be nice for this to work during join that's all

[sonic goblet]

Just to add an option for you, you can add a TextDisplay as the passenger of a player, and set the Text of the display

[lilac dagger]

pretty much lol

[upper hazel]

why wrong with this error? Invalid key. Must be [a-z0-9/.-]: snowdrop:location_key-75_64_69_world_snowdrop-block

i not have forbidden chars

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

[eternal oxide]

_ is not in that list

[pseudo hazel]

it is

but discord is using markdown

[eternal oxide]

ah

[upper hazel]

lol

[eternal oxide]

Your sanitizeKey method looks a little broken

[smoky anchor]

new NamespacedKey(plugin, this.key + "_" + suffix)
And the key is private final NamespacedKey key;
which will include the : character

I think this is the error ?

[upper hazel]

oh

yea

thenks lol

[smoky anchor]

Also, I see no reason for this keys.computeIfAbsent(sanitizeKey(keySuffix)
Could just use the keySuffix, no need to do regex stuff in this case, which I believe is fairly slow

[upper hazel]

regex is slow?

[smoky anchor]

I've been taught it is :D
Or at least doing Pattern.compile or whatever
Which I assume the replace method might do, I do not really know
But the point is that you're doing something pointlessly

[upper hazel]

i see

package name protection simular to namespaceKey protection?

if someone will create forbidden package name for world

[boreal wedge]

can anyone tell me where can i find spigot api docs for 1.18.2? I only find 1.21.3

[summer scroll]

https://helpch.at/docs/1.18.2/

[boreal wedge]

tysm

[boreal wedge]

so I'm a newbie and learning to develop spigot plugins so by the following code i expected that whenever i right click on poppy flower it will be changed to diamond but unfortunately it doesn't change and even didn't throw any error in console how can i achieve this behavior

    public void onInventoryClick(InventoryClickEvent e) {
        if (e.getWhoClicked() instanceof Player player) {
            var clickedItem = e.getCurrentItem();
            if (clickedItem.getType() == Material.POPPY) {
                player.sendMessage("You clicked the flower!");
                if (e.isRightClick()) {
                    clickedItem.setType(Material.DIAMOND);
                    ItemMeta diamondMeta = clickedItem.getItemMeta();
                    diamondMeta.setDisplayName(ChatColor.AQUA + "DIAMOND");
                    clickedItem.setItemMeta(diamondMeta);
                }
            } else if (clickedItem.getType() == Material.BEEF) {
                player.sendMessage("You clicked the beef!");
            } else {
                player.sendMessage("You clicked something else.");
                player.sendMessage(clickedItem.getType().toString());
            }

        }

    }```

[valid basin]

Non spigot related question.

How would one go on securing the Java application (client side anticheat for a server) so it can't be reverse engineered and bypassed by modifying the source code of the application

I'm looking to create it in Java not C based languages

[boreal wedge]

umm i was watching a youtube video and it just worked for him

[lilac dagger]

set the slot with the modified item stack

[boreal wedge]

let me try

tf it worked in survial but not in creative??

[worthy yarrow]

Common issue

Gotta handle for when the player is in creative as well

[sly topaz]

creative inventory doesn't send all the necessary packets, so it is unreliable

[boreal wedge]

hmm noted tysm

[sly topaz]

there's InventoryCreativeEvent or something for creative inventory clicks specifically

[boreal wedge]

really

let me check

[worthy yarrow]

^ it's still a little wonky

but should work with your code

[boreal wedge]

yup it worked

[worn totem]

I donated 10 dollars how can I change my name

[worthy yarrow]

?support I assume?

[undone axle]

[e-mail]

[sly topaz]

?name

[worthy yarrow]

Maybe when optic or choco is around they can handle that

[sly topaz]

?changename

[worthy yarrow]

Ah nice

[sly topaz]

if you're willing to work with the server, I'd do server-side integrity checks as well as code signing

[wet breach]

you can't secure java applications

nor can you prevent reverse engineering

otherwise don't you think mojang would have done that with MC by now?

[slender elbow]

tbf it isn't in mojang's best interest given that they are open about letting people mod the game either way

[wet breach]

well its microsoft, never know

but yes you are right

[valid basin]

Ah code signing so anticheat app can't be tempered with. Alright

[wet breach]

that isn't how that works

[slender elbow]

but ultimately, anything a client can get their hands on cannot be fully trusted and will eventually be tampered with

[valid basin]

What about using launch4j after creating the Java app?

[quaint mantle]

Rootkit

[wet breach]

jar signing just lets an application know that the jar has most likely not been modified and can be trusted

it doesn't prevent modification

[lilac dagger]

there are pretty damn good obfuscators

[valid basin]

Yh but experienced hacker could crack it easily. Obfuscsted or not

[slender elbow]

but ultimately nothing is impenetrable

experienced hackers will always get in your way

it's just an arms race

[wet breach]

no matter the obfuscator it will never hide the java bytecode

[valid basin]

I believe better protection needs to be done but idk if it's possible with Java

[lilac dagger]

well, you can just ask nicely to not get your stuff hacked

[quaint mantle]

Then do server side ac

[valid basin]

Server side ac is horrible bro

[wet breach]

depends how you implement it

[valid basin]

Maybe it'd be good if it works together with client side

[wet breach]

everyone assumes you must run everything in java in the server

[slender elbow]

you cannot trust anything a client gets their hands on, so the solution is to not let that happen at all

[valid basin]

But even polar (best ac on the market) has bypasses

[worthy yarrow]

So doesn't every ac

[wet breach]

it depends

not everything can just be bypassed lol

[worthy yarrow]

Debatable imo

There's always a loophole

[wet breach]

not always, it just depends what kind of server you are trying to put ac on

everyone wants hardcore pvp, which is probably the most difficult to do ac on

however, since I don't care about pvp that much, I set limits lower 😉

[worthy yarrow]

I meant more in a general context, whatever your game might consider cheating I'm sure there are ways to hop over the ac

[wet breach]

well for some things, but not everything

also, heuristics are your friend in regards to AC

[valid basin]

But I suppose even if I create memory integrity check. Some good hacker could bypass it with a custom driver or hardware

[wet breach]

especially if pvp is involved

[valid basin]

Like arduino

[wet breach]

have a large enough data set and its almost impossible to get passed heuristics

[wet breach]

what are you making in java that would require memory integrity check?

[chrome beacon]

Clientside anticheats will get bypassed

You can never trust the client

also forcing your users to install some random program to join your server???

[lilac dagger]

but how hard can you make the job of a hacker so he can't bother anymore?

[wet breach]

depends how bored they are

[chrome beacon]

Some people find breaking systems like that fun and a challenge

[wet breach]

as well as it passes the time

[valid basin]

Checking if memory of the application running eg Mc client and client side anticheat wasn't tempered with

In Java it's harder but not impossible

[wet breach]

since we are dealing with java I can make it to where it doesn't run such things

[valid basin]

Like traditional memory scanning

[valid basin]

Wdym?

Bro I'll make it and you try to crack it

[wet breach]

anything you make in java can be modified to where it doesn't run

[valid basin]

If you crack it props to you

[wet breach]

I can read bytecode and do bytecode manipulations

so I guess good luck getting around hiding bytecode and prevent bytecode from being intercepted and changed

also, you don't have control over which JVM gets used either

to include custom ones

[valid basin]

Runtime integrity check and code signing helps with that

[wet breach]

no it does not

[quaint mantle]

Bro client can do literally anything

[wet breach]

you can't do a runtime integrity check if I modified your code to simply never get the opportunity to launch it

[valid basin]

I could force which one is required to run the game

[wet breach]

not even

[valid basin]

Otherwise you can't join the server

[wet breach]

I can fake the data 🙂

[shadow night]

And I can too

[wet breach]

I get it, you don't want to accept that Java simply isn't a language that was never designed to prevent reverse engineering and the sorts

but that is just how it is

[valid basin]

I could create ByteCode hash check to see if it's modified and then it doesn't run the program

[chrome beacon]

Then you just remove that check

[shadow night]

Anything that runs on my computer is something that I can modify
If it has a check that checks whether something has been modified, I remove the check

[wet breach]

there is no check you could put in place that I wouldn't be able to remove before the client runs

[chrome beacon]

or spoof the data sent like frostalf said

[shadow night]

In short: you cannot control the client

[valid basin]

Bro what if I create a loader and make it so it verifies it externally on my vps for example?

And if there's no connection it doesn't run

[vagrant stratus]

yo nerds, quick question. Any idea on if there's a python lib to render a skin?
Need it for something

[eternal night]

[shadow night]

Doesn't change anything kek

[chrome beacon]

Could just spoof the data

[shadow night]

Exactly

[wet breach]

https://github.com/Sindercube/Skindentity

[valid basin]

Damn alright

I guess c++ is the way then

[vagrant stratus]

An entire website just to render stuff? Yikes

[wet breach]

you were not specific in your request

[shadow night]

Wait till the reverse engineering, assembly master comes

[vagrant stratus]

It's README's also fucked KEK

[valid basin]

Yeah bro go crack vanguard then

[shadow night]

Crack what

[wet breach]

someone probably already has

[chrome beacon]

^^

It already has been

[shadow night]

Just wanted to say that

[valid basin]

Nobody has completely. Unless it's private

[shadow night]

Most cracks like that will stay undisclosed, available only to certain groups of people so the developers cannot easily fix it

[valid basin]

Publicly no

[shadow night]

Ofc

If you post your crack publicly, you are gonna get it patched very quickly

[blazing ocean]

Gotta love when people say that Java is immune to cracking KEK

Me when recaf:

[shadow night]

Remember that one plugin we removed the license check for?

[valid basin]

Who said that bro? I just said that I want to make it harder to crack

[blazing ocean]

Yeah cus the dev said it's uncrackable kek

[wet breach]

anything that runs on my system is under my control fyi. You can't stop me from doing memory dumps, poking at the binary code or using disassemblers to get an idea of some of the things it does etc.

[shadow night]

Yup lol

[blazing ocean]

Yeah as frosty said, you cannot make it impossible. You can obfuscate, but it's still super easy

[vagrant stratus]

that's the only repo I can go off of anyways it seems @wet breach
I've got a bunch of downloaded skins & was hoping to do a quick python script so I don't have to suffer w/ looking at the downloading forms lol

[shadow night]

Eh, it's pointless, just leave it as is

[shadow night]

"you cannot control the client"
- me, five minutes ago

[quaint mantle]

Just hire more moderators 🗿

[wet breach]

lol

[valid basin]

Fair

I wish Java had better protection against ByteCode manipulation tho

[vagrant stratus]

I'm not even sure that site handles dealing with the skin texture id KEK

[chrome beacon]

Doesn't need to

[vagrant stratus]

wait no, it can. These aren't B64'd though lol

[shadow night]

doubt that's possible kek

[wet breach]

Java was originally to cater to businesses and schools

hence why it doesn't have said protections because it wasn't needed for that audience

[vagrant stratus]

ugghhh gotta re-b64 them when loading ig
fucking hell

[valid basin]

Wasn't mars rover made in Java?

[shadow night]

and if there were protections, maybe we wouldn't have mc modding rn

[wet breach]

yeah maybe not lol

[valid basin]

Ah makes sense

[blazing ocean]

I don't think the mars rover needs to be better protected against bytecode manipulation

[vagrant stratus]

Actually, I don't think I hate myself that much lol

[blazing ocean]

I think they'd rather need to be able to do that

[shadow night]

lol

[blazing ocean]

So it really doesn't prove your point

[chrome beacon]

Wouldn't surprise me if it was

[valid basin]

I wasn't even trying to prove my point btw. I just said that mars rover is made in Java

[wet breach]

not sure if there was a point they were making, but you are correct it does back up what I said however 😛

[shadow night]

imagine changing the program of the mars rover on the go. That's neat

[wet breach]

the original target audience simply didn't require such things lol

[quaint mantle]

Always worried about mars rover getting bytecode manipulation by aliens

[wet breach]

however Java became popular and more people became interested and its audience grew but there isn't a way now to add such things into java

especially without breaking everything in some update

[shadow night]

we could fork java

[slender elbow]

if anything, the platform makes it easier to do such things

[wet breach]

well if that happens, we can take it as proof that aliens exist

however it is more probable that the mars rover gets attacked by another rover though since at the present moment mars is currently inhabited by nothing but robots

[shadow night]

imagine finding a random System.out.println("hi we are alien for you") in the mars rover code lol

[vagrant stratus]

lol that's not gonna render the http://textures.minecraft.net/texture/ID stuff

I'll just suffer w/ the downloaded forms

[wet breach]

I think we need to focus on space more so that we can have a battle royale of robots on mars

I am sure people would love that

[vagrant stratus]

Some of these are so quite complex, so I was hoping there was a rendering library lmao

[shadow night]

I agree
or imagine "Space Gladiators"

[wet breach]

exactly

[blazing ocean]

This needs funding

[shadow night]

I really wanna see space gladiators

that would be so fucking cool

[wet breach]

could you imagine nasa reporting that their rover was attacked by robots on mars XD

[blazing ocean]

[wet breach]

they can add it to the list of things they didn't think would happen but did

[vagrant stratus]

Found a three.js project which works... just need to somehow modify it so I can just go through the files in a directory instead of supply the file manually
https://github.com/bs-community/skinview3d

[wet breach]

could always make another script

to feed the files for you

[vagrant stratus]

Probably easier to just modify the three.js code lol

Find the code, feed it into ChatGPT, ask it to do the thing

progress 😎

[eternal oxide]

ChatGPT please evolve into SkyNet

[quaint mantle]

bs community 💀

[wet breach]

this would be nice

[blazing ocean]

I've used this one before

[vagrant stratus]

Yea, it's nice. I dunno three.js though kek

or where the code to get the skin even is lol

oh it's in the html.
Hmm

I definitely need to figure something out though, I have 3.7k+ of these lol

Found one which uses JavaFX, gotta install an older version of Java.
Hopefully this does what I need, probably won't support newer skin types but that's (hopefully) an easier fix since I actually know Java lol

[wet breach]

or just install javafx?

[vagrant stratus]

Used maven libraries still errors unless there's an actual install I can use which doesn't massively change stuff lol

[vagrant stratus]

oh I actually read the README entirely, might be useful after all.
Just thought it was the website itself

[sly topaz]

there are distributions that bundle javafx still, like Azul Zulu or Bellsoft

[vagrant stratus]

Eh. Trying to figure out that repo. example didn't work locally.
Guessing I have to throw it under XAMPP

nope 😄

[river oracle]

JFX is a pain lol you can use it as expected but you need to ensure you should probably use their maven plugin

Also don't forget to use Java modules I've run into issues not using then

Idk if that still holds though

[vagrant stratus]

lol already got rid of that repo kek
probably just gonna deal with the downloaded skins. Don't got the money to commission someone for exactly what I need, and I've spent enough time trying to get third-party stuff to work

[rough drift]

for (final var player : Bukkit.getOnlinePlayers()) {
   if(shouldUpdate(player)) { // Checks if the player's UUID is in the "to update" set
     // Edit one item in their inventory 
   }   
}
```Would this be too heavy to run every say 5 ticks

[chrome beacon]

That's fine

[river oracle]

Yes run it async

[chrome beacon]

but keeping a direct reference to the player 🔫

[rough drift]

lmfao

[rough drift]

yeah I wrote that on discord didnt' want to type too much, but yeah no I use UUIDs for everything

[lilac dagger]

getplayer should work too no?

assuming should update has a list of uuids

[rough drift]

yeah, it's an example ig, the actual code is way more lightweight (iterate over an object list and check if one of three bools is true, has an UUID in case I need to get the player and update the inventory), but I figured "if this is light enough then the lighter one is fine"

the actual thing is like

for (final var user : this.userManager.listUsers()) {
    if (user.optionsChanged() || user.languageDirty() || user.themeDirty()) {
        user.updateItem();
    }
}

[lilac dagger]

oh this us cool

[pure dagger]

why final

[river oracle]

Don't worry about it :3

[pure dagger]

why

[river oracle]

It's not necessary

But it's not bad nor is particularly useful or particularly not useful

[pure dagger]

okay

[lilac dagger]

i like the idea of final, but not that much in local variables

i feel like intellij let's you know if a variable* changes

[robust helm]

chat how do u log stuff in a server network? I was going to use log4j with Loki as central log and stdout for everything but got no idea if thats smart.
Also I made a LoggingAPi which simply configures log4j and not sure if its smart

[sly topaz]

that is a fine approach, I haven't used it myself but heard good things about Loki

I like splunk more but only because I have never had to pay their licensing myself lol

[pure dagger]

how to create custom enchantment book? it needs to be added in anvil

[robust helm]

and how do u set the central log host(loki/splunk)?
rn I use an environment variable, but then id have to set that for each container

[teal plume]

any premium plugin ideas?

[eternal oxide]

chess

[teal plume]

D

[worthy yarrow]

Checkers

[eternal oxide]

use no AI mobs for chess pieces

[worthy yarrow]

Use custom modeled pieces

Make it giant chess

[eternal oxide]

Call it "Slave Chess" where you have to beat the pieces with a stick or use a leash to make them move.

[twilit coral]

Chess was done already tho

Jpenilla has a good repo

https://github.com/jpenilla/chesscraft

[eternal oxide]

make it unique, every time you whip a piece to make it move play an oooohhh sound

[nova notch]

[wide cipher]

trying to get custom heads, get this error when modifying item stacks.

        notNull(item, "item");
        notNull(base64, "base64");

        UUID hashAsId = new UUID(base64.hashCode(), base64.hashCode());
        return Bukkit.getUnsafe().modifyItemStack(item,
                "{SkullOwner:{Id:\"" + hashAsId + "\",Properties:{textures:[{Value:\"" + base64 + "\"}]}}}"
        );
    }```

how can i fix?

[sly topaz]

why are you not using the profile API for this

[wide cipher]

its old code, how do i do it now?

[sly topaz]

hm, the API doesn't support using the base64 value directly

[chrome beacon]

https://blog.jeff-media.com/creating-custom-heads-in-spigot-1-18-1/

^^ covers how to do heads with modern api

[sly topaz]

I hate how they're parsing the json lmao

but welp, if it works

[wide cipher]

thanks

[sly topaz]

doesn't the client do caching based on the UUID used there

if that's the case, it's probably better to not use the same uuid all the time, but I don't know for sure

[young knoll]

I generate the uuid based on the texture url

[slender elbow]

I don't

is there an updated guide
on creating custom enchants

[river oracle]

Yes yes there is

[timid berry]

link?

[river oracle]

One sec I stg I posted jt earlier

[chrome beacon]

You can just use a datapack

[timid berry]

no datapack

[river oracle]

NMS easier lowkey ngl especially if you wanna bundle with your plugin

[chrome beacon]

Yeah

Someone really should add a good way to load datapack from plugin

[river oracle]

https://www.spigotmc.org/threads/1-21-3-register-custom-enchantments-with-nms.651347/

[chrome beacon]

So we don't have to resort to nms

[river oracle]

Quite a bit of work to do it right

[eternal night]

[chrome beacon]

Yeah

[river oracle]

Yeah I know a way to do it usi....

Nvm nvm

[chrome beacon]

Spigot plugins might also load too late

Not entierly sure though

[river oracle]

All plugins load to late I mean I know full well how to execute pretty much every aspect of such an api

It's just a ton of work and for me not worth the time or consequences of that work

[eternal night]

dew it, I am sure it'll be merged as fast as chocos component support

[young knoll]

The server itself loads too late

Because Mojang

[chrome beacon]

Can the Paper bootstrapper do it

[eternal night]

yes

[river oracle]

Yes

[young knoll]

I believe so

[chrome beacon]

Alr good to know

[sly topaz]

you'd have to get configuration phase working before even beginning to implement something like this which is kinda annoying

[young knoll]

?

It works fine?

[river oracle]

I gave up on byte serialization I really just wanna push through my 2 things I got rn tho

[eternal night]

I left as a reviewer 💪

[young knoll]

wtf

[river oracle]

I saw -_-

[sly topaz]

heard there were some issues around it in spigot, not sure if it still applies

[young knoll]

Y2K always ruining my dreams

[eternal night]

config stage is indeed fucked on spigot

[river oracle]

It's been there since July

You can always reopen it it's all done

[eternal night]

just, don't use config stage

[river oracle]

I'm just done maintaining it

[eternal night]

because config stage sounds like reloading

[young knoll]

Smh making me maintain your old code

[eternal night]

and it is a tad weird

[sly topaz]

I'd have merged it as it was tbh

[eternal night]

see, thats why you aren't a spigot maintainer

[sly topaz]

Spigot should really try to push more experimental API, PRs list be looking a lot like wayland repo

[eternal night]

[young knoll]

MD doesn’t have time to merge new features anymore

Mojang keeps changing things every 2 months

!!!!!!!!

[eternal night]

Yea, the constant mini feature drops make life a bit rough for the ecosystem

but, eh, its fine

[young knoll]

By fine

Do you mean

https://tenor.com/view/this-is-fine-gif-24177057

[eternal night]

Well, you just might need a team larger than one maintainer for the job

but that is just my opinion

[young knoll]

Hear that @mdee5, he’s volunteering

[sly topaz]

I mean, the important undelying systems haven't changed a lot with these releases, so in the end it just comes to fixing compile time errors as well as adapting a few patches

[sly topaz]

there's a ton of work being done for item components and what not but spigot doesn't have API for that so it shouldn't be a problem lol

[river oracle]

?nms

[young knoll]

Mojang has gone ham with item components

[river oracle]

read the article please

[young knoll]

Not that I’m complaining

[sly topaz]

not trying to undermine md's hard work or anything, just the current state of affairs being rather frustating

[river oracle]

I'm not going to walk you through what it tells you to do

[young knoll]

I can finally make an edible Diamond sword that looks like tnt

[eternal night]

Yea. If I was just one guy maintaining spigot and, yknow, make a living, I doubt there would be more work on the PR queue either

[sly topaz]

I like the new overlay stuff

[young knoll]

I haven’t even looked into that a ton yet

[sly topaz]

I mean, paper has like a gazillion people in their team and their PR list don't be looking all that different

[young knoll]

But I know it’s quite powerful

[young knoll]

Gottem

[eternal night]

ehhh

[slender elbow]

but it also has a ton more activity

[sly topaz]

while it is true that it'd be better with more human resources being able to take a hand at it, it ultimately falls apart when considering one has to have way too much knowledge in order to fairly review and merge these anyway

[young knoll]

And then you get differing ideas into the mix

[sly topaz]

and lots of bikeshedding 😛

[young knoll]

That’s why they wouldn’t let me on the paper team, I wanted to rewrite it in JavaScript

But apparently that doesn’t align with their long term goals for the software, smh

[river oracle]

yeah I mean good thing I'm not in charge or we'd all be using ViewBuilders right now for literally everything

want to check if the player joined? Well their is an InventoryView builder for that

[young knoll]

“Why does this potato have an inventory view?”

[river oracle]

MenuType.POTATO.builder()
 .check(player)
 .logic((ItemStack possiblePotato) -> {
 player.getInventory().addItem(possiblePotato);
}).build().open();```

@eternal night sneak peak at CabernetMC Api 😉

just showing you what ya'll are up against

[eternal night]

sorry I was busy with comparing commits in the past 2 weeks

[eternal night]

was just too hurt by this

[river oracle]

surely that can't be hard

you can just hand count spigots

[young knoll]

His feeling are very fragile

Like a piece of

Paper

[eternal night]

indeed

tbf it is a bit unfair because all our update work is separate commits

but in the last 3 weeks, paper is chilling at 50 commits vs craftbukkits 16

[sly topaz]

lol, for the record, I do recognize that the magintude paper works at is completely different when compared to spigot, but it still suffers from much of the same problem

[eternal night]

For now ™️

[river oracle]

yeah wait till they bring in John Developer

[slender elbow]

what are you talking about

[river oracle]

he's going to go crazy

[slender elbow]

spigot is perfection

[eternal night]

tbh, the worst part about paper is the fact that rebasing and reviewing patches is annoying

[slender elbow]

you're annoying

i am sorry, that was mean

i love you

[eternal night]

thanks

[timid berry]

man

buildtools takes ages

[river oracle]

slow computer?

or slow internet?

it only takes like 2-3 minutes usually

[sly topaz]

it takes like 3 mins to me and I run a potato

[timid berry]

i dont know

java -jar BuildTools.jar --rev 1.21 --remapped

[young knoll]

The worst part about paper is they keep releasing builds which means userdev has to run again

[timid berry]

i did this

[sly topaz]

I'm surprised you guys haven't come up with a way to optimize that workflow given y'all got to do it so often

[young knoll]

Smh you better compensate me for all this CPU usage

[eternal night]

Well, not for much longer

[sly topaz]

well, more targeted than it is now, rather, paperweight was a huge step forward I'm sure

[river oracle]

they're going to optimize it with a very soft spoon

[young knoll]

Paper soft spoon

Coming with hytale, elder scrolls 7, half life 3, and me getting a girlfriend

[eternal night]

coll

imma bet you a full minecraft account (not mine, I'll buy you a new one)

that soft spoon will be here before component PR is merged

[slender elbow]

hytale will come after half life 3

i have info

[river oracle]

what comes first heat death of universe or component PR

[young knoll]

Idk you guys have been talking about this spoon for a while

Probably since they hytale teaser tbh

[eternal night]

fair fair

but you gotta think of it that way.
Every update we have to do with spigots ferflower fork is another day we get more depressed and delusional

[sly topaz]

last time I was on Paper's discord, there did seem to be actual progress towards turning off the tap, if one may call it that rather than just the hype around it that has been around for years

[eternal night]

paperweight-core iirc is ready yea

userdev and patcher (fork plugin) are not iirc, but they should be somewhat easy

[young knoll]

Are you prepared for 1000s of people complaining their spigot plugins aren’t working

[eternal night]

Well, see, that won't really happen

hence soft spoon

[timid berry]

uh

[sly topaz]

it won't happen immediately rather

[timid berry]

i did the build tool

stuff

and added it

[eternal night]

Yea

[timid berry]

pom.xml

is no longer

red

[sly topaz]

at least until I make my PR "remove all deprecated spigot methods"

[timid berry]

but my code is still red

[eternal night]

the legacy text methods are gonna be the last ones to go

[eternal oxide]

clear cache and restart IDE

[young knoll]

But when it does happen

Are you ready

[eternal night]

yes

everytime it happens imma pull a coll and

[timid berry]

how can i do that

[eternal night]

https://tenor.com/oZs2ib97vYR.gif

[timid berry]

"clear cache"?

[eternal oxide]

file menu

[young knoll]

Fair enough

[river oracle]

Couldn't you just keep around all the string methods and just YOLO them through MiniMessage kekw

[eternal night]

that would be worse than removing

[young knoll]

Minimessage explodes with the § character

[timid berry]

this?

[river oracle]

its okay § is but a suggestion

[young knoll]

And by that I mean it just yells at you and refuses to do its one job

[eternal night]

We just cope that we'll get hava string templates by then

[young knoll]

Smh

[eternal night]

at which life is good

[sly topaz]

before doing that, did you add special source properly to your pom, and did you sync the changes

[timid berry]

is this concering

[timid berry]

how to sync?

before i compiled and added the spigot1.21.1

it was allred

but now its normal

in the pom.xml^

[sly topaz]

remove the dependency to spigot-api

and you can sync by pressing the floating button that pops up when you change your pom

[barren peak]

how do you get the SkullMeta set for a player head such as this one:
https://minecraft-heads.com/custom-heads/head/4132-steve-gold
when you only have the texture value

[sly topaz]

?skull

[river oracle]

I got it

[timid berry]

before i synced i had this much red but now i have more

from the guide you shuold beable to see what you did wrong

[sly topaz]

the spigot-remapped-mojang artifact gets installed to your local maven repository when you execute buildtools with the remapped flag

[sly topaz]

I can't blame people for skimping through guides like these tbh

[timid berry]

i had it here

like in the guide

[river oracle]

yeah and so why did you switch to spigot-api

[timid berry]

because it was there before

[timid berry]

look here

i had 2

spigot

and spigot -api

[sly topaz]

I said to remove spigot-api not spigot

what about this one guys

[sly topaz]

did you sync again

well, it is recognizing craftserver now at least

is it called MinecraftServer in mojmap or something else

[timid berry]

https://www.spigotmc.org/threads/1-21-3-register-custom-enchantments-with-nms.651347/

im not sure

im following this

[sly topaz]

hm

do you still have the file you added in libraries perchance

if so, remove that

[timid berry]

still there

[grave plover]

lol you got a typo there

see closely

[timid berry]

ine

mine

raft

wow

[grave plover]

[timid berry]

wow

its like a chain of reactions

u fix one thing

and everything else

gets fixed

thanks

[grave plover]

in Germany you would say, "Gänsehaut"

[grave plover]

np

[timid berry]

gansehaut

[sly topaz]

hawkeye in the flesh

would've never spotted that

[grave plover]

haha

[river oracle]

bro how tf you notice that

[timid berry]

on load is on enable right

[river oracle]

method inside of method 💀

do you even know java?

[timid berry]

na

i only know

scratch

anyways

[sly topaz]

onLoad

[timid berry]

hmm?

what is onload?

[sly topaz]

a method that runs on plugin load

override that in your main class and do it there

[timid berry]

huh???

[sly topaz]

you do realize that you put a method inside a method right

[timid berry]

i do

[river oracle]

please learn java before using the API it'll be helpful

[timid berry]

but i need to put it under

onload

[sly topaz]

only the logic that runs on load, not the method declaration/definition itself

[timid berry]

oh i see

do i call

unfreeez

registry

on load

[sly topaz]

yes

you just can't have a method inside a method in java

[sly topaz]

looks good, just follow the rest of the guide now and you should be good

[timid berry]

i dont think this is it

[sly topaz]

getAllTags is one of the methods that was earlier in the guide, you should have copied that too

or if you copied it in some other class, just reference it properly

[river oracle]

maybe if you're struggling this hard with the code you should try datapacks

[timid berry]

oh id id it

i forgot

to copy

scroll down

should i rename

oh i got it

he made a typo

[sly topaz]

they didn't, just the method name is now bindTag in the newer version, it was bindTags in 1.21.1 though

[timid berry]

i see

[paper viper]

You don’t need or else

Also you should learn about basic stuff at least

[timid berry]

i know basic stuff, i just never did complicated stuff

[paper viper]

Type a period, and then see the methods that IntelliJ shows

Don’t send a screenshot of it to me, figure which method you think would work the best

[timid berry]

im following a guide

but this guy

writes it like that

so idk

[paper viper]

Guides get outdated

Code gets updated

Code changes between versions

Old guides won’t always work

[sly topaz]

the guide is updated rather, since they're trying to adapt a 1.21.3 guide to 1.21.1

[paper viper]

Oh, the same but vice versa

[sly topaz]

I know right, rarely the case lol

[timid berry]

oh okay

do you know what i should

put

instead of or else null?

i have no clue

yes ive scrolled

through

[sly topaz]

the method is called getHolder in 1.21.1 it seems

[paper viper]

When you type a period you need to look at the method name and IntelliJ suggests the methods that would make the most “sense” on top

Look at the ones on top and see the return types and the method name

[timid berry]

thanks

[sly topaz]

I was really confused for a hot second since I was looking at what I thought was the 1.21.1 mappings forgetting that I had switched to the 1.21.3 ones and the method names matched lol

[paper viper]

Yeah

But I guess, why not use 1.21.3?

[timid berry]

hmm

i dont wanna sound dunmb

but

[paper viper]

You need to define a variable for enchantId

[timid berry]

yes

but the other thing

it applies

my enchantment

to those items?

[paper viper]

I just jumped into this conversation so I don’t know the full code but do you mind sending the full code?

[sly topaz]

read the guide, it explains it there

don't just copy the code, read carefully what it says

[timid berry]

im reading

im just wondering

for lines like that

like

i should put it under some event

like anvilenchant

[sly topaz]

that is part of the enchantment definition

all this code goes after the unfreeze call in onLoad

[timid berry]

oh boy

this guide

is gonna drive me crazy

[eternal night]

[sly topaz]

I mean, you wouldn't have all these issues if you were on 1.21.3 lol

[timid berry]

yah

but then the issues

i fixed

[sly topaz]

I asked claude to make an API from the blogpost and it made one kind of similar to Paper's one lol

[eternal night]

best claude

[timid berry]

only if it was this simple

[sly topaz]

if you switched to 1.21.3 you could just ask chatgpt/claude/mistral to encapsulate the logic onto an API like me and then just do that

work smart not hard 💁

[timid berry]

ugh

i just wanted to create a simple sistem

add some sort of meta data to a book

call it enchanted

let players combine the book and sword via anvil

then when they use the sowrd and attack

if sword has meta data custom enchant

give victim

an affect

😭

[young knoll]

And it works?

That’s the craziest part

[timid berry]

yo

what if there was a library

no way someone didnt simply the process

[young knoll]

¯_(ツ)_/¯

Data driven enchantments aren’t that old

[timid berry]

yah

but i still dont get it

the guide is driving me nuts

[sly topaz]

I feed it the whole guide so all it had to do was to create abstractions, LLMs excel at that kinda thing

[young knoll]

Idk sometimes they just hallucinate new functions

At least in my experience

[sly topaz]

I actually had to copy the outerHTML of the post, feed it to mistral and tell it to scrape all the text from it to only then feed it to claude to generate the API, couldn't have done that with just mistral since it does what you just described

claude is pretty good at staying concise

[young knoll]

What’s mistral

We got another player in this game now

[sly topaz]

mistral is the completely free one, no strings attached

so you don't have a limit on how much you can use it

[young knoll]

There’s gotta be a catch somewhere

[sly topaz]

(well, I'm sure there's a limit, I just haven't used it enough yet)

[young knoll]

Computation time doesn’t grow on trees

[sly topaz]

their model isn't as good as the other ones

but is is good enough to give menial tasks like the above one so you don't waste all your claude/chatgpt tokens on a single response lol

also bigger context window

[timid berry]

can u send me the guide

oh is it the same guide

@sly topaz what 1.21.3

[river oracle]

if you're gonna use paper please go to their discord too, https://docs.papermc.io/paper/dev/registries

[timid berry]

i wont

its default

on new

[quaint mantle]

Is it possible to make a plugin add mod like features without making the player download it? (I haven’t started learning programming to make plugins yet) with custom items at least and probably blocks

[river oracle]

Long answer -> Yes
Short answer -> No

Adding custom items, and blocks with plugins is very far from straightforward. It would require a pretty advanced knowledge of the plugin eco system packets, java etc etc. It would be extremely difficult especially for a beginner in programming. While you can hackily execute most things mods can do with plugins, the actual implementation is often times complicated

this also requires combination with resource pack too

These concepts are pretty far from first plugin type of project

as a first step you could maybe start with Custom items they're fairly easy as its just a resource pack with some model data, but blocks would probably hell on earth for a beginner

Hello, I am attempting to create a player head, however, when I add it into my GUI it shows up as without a skin (see code below)

            // Convert the UUID to an offline player
            OfflinePlayer player = Bukkit.getOfflinePlayer(adminUsers.get(i));
            // Create the head of the player
            ItemStack playerHead = new ItemStack(Material.PLAYER_HEAD);
            // Get the meta of the skull
            SkullMeta skull = (SkullMeta) playerHead.getItemMeta();
            // Check if the skull is valid
            if (skull != null) {
                // Format the name of the player properly
                skull.setDisplayName(Placeholders.formatPlaceholders("&c" + player.getName()));
                // Set the owner of the skull
                skull.setOwningPlayer(player);
                // Save the skull's player data
                playerHead.setItemMeta(skull);
            }

I have confirmed that the item meta is updating because the name works, however, the skin is just a default head. Any ideas?

[river oracle]

Lots of player skull questions today huh interesting.

Get the player profile of the admin and update it

Do note this should be done asynchronously so you'll need to set the item in the inventory once the request is completed

[granite burrow]

I tried that. I just found out what the true issue is. The player is offline so the head doesn't show the proper skin (Not the async part but I did the profile thing)

[river oracle]

I gave you solution

You have to get the profile but then update it from the web request

[granite burrow]

oh so you want me to get the profile from an API? or via OfflinePlayer#getPlayerProfile()? Because doing the offline player one doesn't work, even after making it async and spawn into the GUI about 20 seconds later

[river oracle]

Should not take 20 seconds 💀

[granite burrow]

Was for testing cuz the 1 second I put yieled no change

[river oracle]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/profile/PlayerProfile.html#update()

final InventoryView view = ...;
final OfflinePlayer player =....;
final PlayerProfile profile = player.getPlayerProfile();
profile.update().whenComplete((exception, profile) -> {
  if (exception != null) {
    ... properly handle exception
  }

  final ItemStack stack = new ItemStack(Material.SKULL);
  final SkullMeta meta = (SkullMeta) stack.getItemMeta();
  meta.setOwningProfile(profile);
  stack.setItemMeta(meta);
  
  view.setItem(0, stack);
});
