development

[royal hedge]

pretty not heavy

heaviest bit would be calling the event handler

[merry knoll]

you can just use squared distance

[river solstice]

yeah, but its for displaying it to the players

[torpid raft]

you'll be fine

imo

it's just math, as long as you arent trying to do it hundreds of thousands of times a second youre probably safe

[merry knoll]

should still be fine honestly

[river solstice]

hmm, i suppose will have to find out manually

[dense galleon]

Been told off from using Redis for crucial permanent network-wide data from the velocity devs

Better off accessing the database directly

[spiral prairie]

Supposing each player does 20cps, you'll have 800 roots per second, which is nothing. It doesn't make sense to worry about performance here while a regular PC can crunch 100s of gigabytes per second

Okay maybe not hundreds but when not limited by a drive or ram lanes/connections, it's not little

[dusky harness]

Players can also only damage 2 times per second

So 40 players is only 80 max

Just saying :))

[spiral prairie]

okay well then don't even think about it haha

my ancient Ti83 overclocked could do that

actually probably not even overclocked

considering it can play doom

[merry knoll]

it entirely depends on the type of data, permanent yes just use sql. if you need to "sync" constantly redis works the best

[hoary scarab]

Damage is just minimized if its not a hit after cooldown. It still does damage.

[torpid raft]

sus

my ti84 ce can probably only take a few dozen square roots a second at most

at least using tiBasic, maybe its a different story using z80 asm

[atomic trail]

Does someone know how this is not an instance of the reference? (Using IntelliJ debugging tool)

The result is an instance of SQLiteDatabase and the reference is the SQLiteDatabase class

[torpid raft]

reference is type Class

i think you're asking if a Class object is an instance of itself which doesnt make sense

or am i wrong idrk

[atomic trail]

I don't think it's type Class. I used the parameter as SQLiteDatabase.class

[torpid raft]

yes

that is type Class, what else would it be

[atomic trail]

type SQLiteDatabase? Not sure how else to setup the parameter

[torpid raft]

https://stackoverflow.com/a/10076748

oop big link

[atomic trail]

Lol

But shouldn't it be an instance of both?

Instance of class and SQLiteDatabase?

It also implements an interface called Database which it should also be an instance of right?

[torpid raft]

this is the interesting bit

note that your reference argument in your getConfig method is type Class<T>

[atomic trail]

But this is a comment on that comment

[torpid raft]

yes

they are both correct

or i guess yeah the comment is more right

but the idea that Class represents classes is correct

[atomic trail]

But this can't be setup using an Object. I need some sort of Type

Not sure how else to do it

[torpid raft]

what exactly are you trying to do

[atomic trail]

This might explain it better https://paste.helpch.at/ebejejowud.typescript

public class SQLiteDatabase extends Database implements LocaleReference {

[dense drift]

reference.isInstance(reference)

[torpid raft]

is there a reason you have to do this fancy Class stuff at all? it seems like you just want to provide different implementations to storing a config

[dense drift]

you want to check if Object result is an instance of reference

[atomic trail]

bruh I'm so dumb

Ofc

or well if reference is instance of result

[torpid raft]

other way around

[atomic trail]

wait both would work actually

[torpid raft]

result is an instance of the class represented by reference

[atomic trail]

reference.isInstance(result) and result instanceof reference would both work no?

[torpid raft]

no

since reference is a "Class" object that represents an actual java class

[atomic trail]

This works how I want tho

    public <T extends LocaleReference> T getConfig(Class<T> reference, String name) {
        Object result = configs.get(name).get();
        if(!reference.isInstance(result)) {
            return null;
        }
        return (T) result;
    }

[spring crescent]

Is there an easy way to make my SQL queries compatible with SQLite? I feel like I have to rewrite my entire connection code to support both 😢

[ocean raptor]

mostly they should work

and almost every time if a statement don't exists in sqlite there is an alternative for it that works for both mysql and sqlite

[spring crescent]

Sweeeet I had only one situation where I had to handle some oddity. SQLite support implemented 👍

[atomic trail]

What's the correct SQLite query for checking if a table contains a specific value that is not marked as the primary key?

For example I want to check if items contains an item with given name

"CREATE TABLE IF NOT EXISTS items (" +
                        "uuid VARCHAR(36) PRIMARY KEY, " +
                        "name VARCHAR, " +
                        "price INTEGER" +
                        ");"

[dense drift]

just do a select query?

[sterile hinge]

why would you do that in first place

like you can do it, but if you don't specify an index for the affected columns, you might run into performance issues

[atomic trail]

It's basically just to warn the user that an item with the selected name already exists, but it should definitely just be cached instead

Or idk, SQLite is pretty fast, is caching it in the jar worth it?

[sterile hinge]

probably not, but the scaling factor of the db depends on the indexes you're using

SQLite can't magically search through n strings in O(1)

[atomic trail]

How does it handle it based on primary key then? There's some efficiency way of checking that right?

[sterile hinge]

primary key means unique, combined with the data type it can create a unique index for that column

[torpid raft]

if you index the item name column it should be bearable

still depends on exactly how many items you plan on having stored though

you can do some benchmarking of your own to see how long it takes

[dense drift]

Does spigot have an api for getting the base64 texture string of a skull? PlayerProfile only has methods for getting the URL 😦

[atomic trail]

I just used this when I needed it https://github.com/deanveloper/SkullCreator/blob/main/src/main/java/day/dean/skullcreator/SkullCreator.java

[dense drift]

yeah well, I need to get it

[atomic trail]

Yeah true but it's just one class

[dense drift]

Not the nicest code but it does its job D:

if (ServerVersion.HAS_PROFILE_API) {
    val profile = (meta as SkullMeta).ownerProfile ?: return null
    val textureUrl = profile.textures.skin ?: return null
    val json = "{\"textures\":{\"SKIN\":{\"url\":\"$textureUrl\"}}}"
    return Base64.getEncoder().encodeToString(json.encodeToByteArray())
}```

[spiral prairie]

Me and a friend of mine are doing a coding project that includes frontend/backend and I just made the endpoint diagramm containing stuff like /api/laps or /api/teachers or /api/classes etc. Now he's telling me that we decided on a REST API and thus everything should have one endpoint and the resource you want to access is put into the body of the request. I have never seen such an API, nor ever thought about REST APIs in that way. Can somebody tell me that his thoughts aren't exactly right?

[dusty frost]

yeah that sounds like a GraphQL API lol

REST is all about having different resources mapped to different urls, using like GET POST PUT PATCH etc. to confer different meanings about those resources

[torpid raft]

curl -X GET me.com/api/v1/bitches

[spiral prairie]

Imo doing that with HTTP requests is worse than sending the status code as a field in the response body and with an HTTP status code of 200

[dusty frost]

I mean there's pros and cons to both

but having a single endpoint and doing routing behind that is a big part of GraphQL, which is maybe what they're confusing it with?

[spiral prairie]

I don't think so

[minor summit]

inb4 response is 200 but body is a nicely done 404 html

[spiral prairie]

They sent me a redhat link called "what is a rest api" and said "where is it written that you have multiple endpoints"

[dusty frost]

https://aws.amazon.com/what-is/restful-api/

send him this

The server identifies each resource with unique resource identifiers. For REST services, the server typically performs resource identification by using a Uniform Resource Locator (URL). The URL specifies the path to the resource. A URL is similar to the website address that you enter into your browser to visit any webpage. The URL is also called the request endpoint and clearly specifies to the server what the client requires.

that part is the most useful lol

[spiral prairie]

Okay they meant RPC

[dusty frost]

ah

[spiral prairie]

is that like controlled RCE?

[dusky harness]

isn't RCE remote-code-execution 🥲

[spiral prairie]

ye

[dusky harness]

ohh

oh thats why you said controlled

[dusty frost]

I mean it's just different ways of framing APIs lol

RPC is better for stuff that doesn't fit the resource model of REST well, like doing complex actions and stuff

but like meh, tons of web tooling is centered around what is basically REST, so it's not super worth it imo to do something like that

especially if other people are going to be consuming it or anything

[spiral prairie]

But like simple resources and get/put/patch/delete requests are more REST than RPC I'd say

[dusty frost]

I mean by definition they are yea lol

[atomic trail]

Is this as efficient as using a combined future?

        for (Quest quest : registry.getAll()) {
            this.update("INSERT OR REPLACE INTO quests(identifier, type, icon) VALUES(?, ?, ?)",
                    statement -> {
                        statement.setString(1, quest.getIdentifier());
                        statement.setString(2, quest.getType().toString());
                        statement.setString(3, quest.getIcon().toString());
                    });
        }

[minor summit]

consider using batches

updateBatch("insert blah blah", statement -> {
  for (quest ...) {
    statement.setString(...);
    statement.addBatch();
  }
});

updateBatch would be basically the same as update, but instead of calling statement.execute() it'd call statement.executeBatch()

[atomic trail]

Ohhh, never heard of batches for cf before

Will look into it, thanks!

I changed it to this, which does basically the same tho I think

    public CompletableFuture<Void> save() {
        CompletableFuture<Void> combinedFuture = CompletableFuture.allOf(
                registry.getAll().stream().map(quest -> this.update(
                        "INSERT OR REPLACE INTO quests(identifier, type, icon) VALUES(?, ?, ?)",
                        statement -> {
                            statement.setString(1, quest.getIdentifier());
                            statement.setString(2, quest.getType().toString());
                            statement.setString(3, quest.getIcon().toString());
                        })).toArray(CompletableFuture[]::new)
        );
        combinedFuture.join();
        return combinedFuture;
    }

[minor summit]

uhhh

except that it's worse

[atomic trail]

Oh lol

[minor summit]

batching like this will use a single connection once, as if it was a single operation

the query itself is "compiled" once in the server and then the params are sent following it

[minor summit]

doing this you're just doing the same thing over and over again, + depending on what thread pool you're using under update you might thread-starve or take an absurdly long time which is no bueno

[atomic trail]

Does executeBatch work for updates as well as queries? As in executeQuery() and executeUpdate()

[atomic trail]

Ahhhh I see

[minor summit]

yes

[atomic trail]

Why is there a difference between executeQuery() and executeUpdate() then?

[minor summit]

they are more so "helper functions" around execute()

[atomic trail]

Ohhh wait I can't use executeBatch for queries tho, only updates

As I need the resultset

[minor summit]

you can

[atomic trail]

Which is only returned from executeQuery

Oh

[minor summit]

you need to get the result set separately

[atomic trail]

Just

                statement.executeBatch();
                ResultSet resultSet = statement.getResultSet();

?

[minor summit]

but, insert doesn't return a resultset afaik? not sure why you'd need that?

[atomic trail]

This is not for the insert part

I just have general query and update methods

[minor summit]

uh

[atomic trail]

https://paste.helpch.at/sesedimese.java

Could probably get a lot better

Or idk

Got help from BM with it

[minor summit]

you don't need batching when doing regular select queries

batching is for update/insert basically

[atomic trail]

Oh okay, so I can remove the executeBatch rly

[minor summit]

i mean

queryBatch in general sounds like not useful

[atomic trail]

Alright, perfect, thank you :))

It made the code a lot cleaner as well yeah

    public CompletableFuture<Void> save() {
        return updateBatch("INSERT OR REPLACE INTO quests(identifier, type, icon) VALUES(?, ?, ?)",
                statement -> {
                    for (Quest quest : registry.getAll()) {
                        statement.setString(1, quest.getIdentifier());
                        statement.setString(2, quest.getType().toString());
                        statement.setString(3, quest.getIcon().toString());
                    }});
    }

oops

forgot the addbatch

[minor summit]

make sure whatever registry.getAll() returns is thread-safe, as it's gonna run on a separate thread, or copy it beforehand, the same goes for Quest

[atomic trail]

It's just this, so I'd assume so

    public Collection<Quest> getAll() {
        return quests.values();
    }

quests is a HashMap

Oh HashMaps are not thread safe

Ahhh ConcurrentHashMap

Will this be thread-safe then?

[merry knoll]

looping is nearly never thread safe

you can copy a concurrent hashmap

then loop over it though

[atomic trail]

I only need the values from the map tho

[minor summit]

you can copy the values before calling updateBatch, then use that copy inside it

List<Quest> quests = List.copyOf(registry.getAll());
updateBatch(.... {
  for (... : quests)
});

[atomic trail]

So List is thread-safe?

But Collection isn't right?

Not sure what determines whether or not it's thread safe sry

[minor summit]

no that's not how it works

the map can be modified anytime from the main thread since you're running on another thread

if you copy the values, the copy won't be modified

[atomic trail]

But with this, the map should still be concurrent right?

[minor summit]

no

since you are copying the collection before using it in another thread

using getAll directly in another thread runs the risk of the main thread modifying the map (removing/adding a quest) and the query can blow up

by copying the list, you basically take a snapshot of the collection, so subsequent additions/removals are not going to alter the copy

[atomic trail]

Ahhhhh yeah now I understand what you mean

That makes sense

[dense galleon]

If an event is called asynchronously, does an error or warning show up?

I have been troubleshooting one of my plugins for ages, and I found out I am calling an event async accidentally, and that was what broke most things though there was no error or warning in the console

[hoary scarab]

Not always. Some events will respond with an error others won't.

[dense galleon]

Mine is a custom event

How would I implement an error or warning for that?

If it is possible?

When calling an event, should I do Bukkit.getPluginManager().callEvent(event) or event.callEvent()?

[dense galleon]

Got it, they're the same 🥲

[atomic trail]

Use Thread.currentThread() I guess

Not entirely sure but that would do the job I think

[pulsar ferry]

callEvent(event) already does the check, if an event is set as async it can only be called async, if the event is set as sync it can only be called sync .. on paper at least

But if you really need to check, Bukkit.getServer().isPrimaryThread()

[dense galleon]

yeah it was a whole separate issue

To do with completable futures

[dense galleon]

⚠️ noob question incoming ⚠️

    @Override
    public void spawnCrystals(Player player, int amount) {
        SpawnCrystalsEvent event = new SpawnCrystalsEvent(amount, player);
        Bukkit.getPluginManager().callEvent(event);
        if (event.isCancelled()) {
            return;
        }
        amount = event.getAmount();
        player = event.getPlayer();``` to make sure my custom event can be cancelled and also allows to change the values of `amount` and `player`, is this appropriate?

I haven't really messed around with custom events much in all my years of plugin development lol

[dense drift]

I would avoid overriding the method's parameters, but yeah, that's how you usually do it

[dense galleon]

Okay thank you

[abstract gate]

can i make a config.yml file and have that used as the default config?

[hoary scarab]

yes. Default of what though?

[abstract gate]

my default plugin config

[abstract gate]

instead of config.addDefault()

can i just create a yml file that created by default with the plugin?

[dense drift]

Yes, call JavaPlugin#saveDefaultConfig() somewhere

[hoary scarab]

Yeap. Add it to your project and use JavaPlugin.getConfig().options().copyDefaults(true); true will force write paths.
Or what gaby posted.

[abstract gate]

where do i put the config.yml though?

[hoary scarab]

In your project. Usually in resources.

[abstract gate]

ok

[abstract gate]

is it possible to get custom heads without using a name or GameProfile?

[hoary scarab]

[dense drift]

org.bukkit.profile was added in 1.19

[dense drift]

Well, what other options are there??

[abstract gate]

what about 1.12 because i dont have a GameProfile in my autofill menu

[spiral prairie]

[mild stirrup]

How can i set the the itemMeta for a player_head so i can set the Skull Owner ? or change the texture of it ?

[terse osprey]

can you add data to an itemstack that can't be seen my the player?
like custom key, values?

[dusky harness]

btw technically, I think NBT/PDC can still be seen by clients if they have like a mod, so don't put something that absolutely shouldn't be shared
haven't confirmed it tho

[ocean raptor]

yeah they can

but not with vanilla client

it should be fine in many cases but just be sure you don't hide any passcode or smth

[minor summit]

encrypt it

[dense galleon]

Hmm question

If an item spawns in a world through a glitch which duplicates it, will that be caught in an ItemSpawnEvent?

I imagine the answer is 🤷‍♂️

[hoary scarab]

@mild stirrup, @abstract gate

ItemStack skull = new ItemStack(Material.PLAYER_HEAD);
SkullMeta skullMeta = (SkullMeta) skull.getItemMeta();

if(ServerVersion > 17) {
    PlayerProfile profile = Bukkit.createPlayerProfile(UUID.randomUUID(), "<Name>");
    PlayerTextures profileTextures = profile.getTextures();
            
    profileTextures.setSkin(<TextureURL>);
    skullMeta.setOwnerProfile(profile.update().getNow(profile));
}else {
    GameProfile profile = new GameProfile(UUID.randomUUID(), "<Name>");
    byte[] encodedData = <Base64>.getBytes();
    profile.getProperties().put("textures", new Property("textures", new String(encodedData)));
            
    if(field_profile == null)
        field_profile = new ReflectField(skullMeta.getClass(), "profile");
            
    field_profile.setValue(skullMeta, profile);
}
```This should be ran async. Also make sure to adjust accordingly. This can't just be copied and pasted.

I've been using LAMP for all my projects, really noce

[hoary scarab]

Full code at the time was ConsolOutput.instance.debug("Generation (" + (uuid != null ? uuid.toString() : data) + "), Skull: " + skull.toString());

I do use eclipse.

[sterile hinge]

Well you either found a bug in the eclipse compiler then or the exception occurred somewhere else

[hoary scarab]

That's the line the stack trace posted lol

That's why I was confused since it cleary checks null.

Why would the compiler be the issue? The code is fine.

[sterile hinge]

because compilers can have bugs

if the code is fine, what else would it be

[hoary scarab]

🤷 Java
Idk it was only debug code that didn't even help with the problem I was debugging.

[oak vessel]

https://www.spigotmc.org/threads/methods-for-changing-a-massive-amount-of-blocks-up-to-14m-blocks-s.395868/

Is there an updated post on this for later versions since they changed to using mojang mappings.

As a lot of the methods in here uses spigot mappings and some methods no longer even exists anymore.

[sterile hinge]

just use paperweight and don't care much about mappings

or use an API to do the work

[hoary scarab]

Just look up the new mappings or using spigot/papers maven plugin to convert mappings.

[oak vessel]

The issue is uh half the methods don't exist as far as I can see, e.g. Chunk(the nms on)#a which returns a ChunkSecion(spigot mappings) I could not even find a method that returned a ChunkSection (or LevelChunkSecion)

[hoary scarab]

Because they are named differently per version. Which is what most people use the maven plugin for.

[oak vessel]

Doesn't paperweight use some sort of mappings as well? (I've never used paper weight before)

[sterile hinge]

it uses mojang mappings

[oak vessel]

Yes, but Ive gone to https://nms.screamingsandals.org/1.20.4/net/minecraft/world/level/chunk/LevelChunk.html and checked for return values and no return gave the thing I needed.

[oak vessel]

Then I'd have to convert them into mojang mappings still.

[sterile hinge]

what

you simply write the code

[oak vessel]

😭

[oak vessel]

Did not find that but thanks i guess.

[sterile hinge]

yeah the mappings viewer doesn't show inherited methods

[oak vessel]

That's why I see so likely checking decompiled is better.

[sterile hinge]

no, just writing code is better

auto completion basically already does everything you want

                </div>

[shell moon]

idk if you have vertical-align: middle already

[broken elbow]

Am I missing something here? What exactly is class d-flex. Is this a class made by you? If you're using TailwindCSS, why are you creating custom classes?

Also, I think you want to use content-center not align-items-center.

[river solstice]

d-flex is bootstrap iirc

[river solstice]

maybe add some padding?

[broken elbow]

Oh. First time I see someone mixing tailwindcss with bootstrap.

[void orchid]

Mind clarifying what you mean by fallsafe's Retry policy not allowing custom entry logic like entry4j did?

[sharp cove]

Yes sorry, didn't know i had that installed.
I used jetstream and it was automatically in it xD

But it was fixed

The h1 had a margin-bottom

Just set it to mb-0

[broken elbow]

Yeah. My bad. Before I do that though, I just want to clarify that I've just ended up writing my own little retry service.

Retry4j has a method called retryOnCustomExceptionLogic which takes a Function<Exception, Boolean> which lets you decide if you want to retry or not.

From what I've seen, failsafe specifically states that only specific exceptions can be handled. So you have to give it the exception types you want it to retry on.

[spring crescent]

Yeh it turns out the reason I was getting the problem was because I had my dependency listed as “provided” and included it in plugin.yml under “libraries”. Which removing that and violating it works. However now I have an issue that my plugin is 11MB. Any idea how to reduce that size down, but still have access to the hibernate dependency?

[void orchid]

Ah, gotcha. Yeah, you're right. Thanks for the clarification

[minor summit]

By default, policies handle any Exception that is thrown. But policies can also be configured to handle more specific exceptions or conditions
https://failsafe.dev/policies/#failure-handling sounds like you don't have to specify any particular exception, but that you can handle specific exceptions in a specific way

[broken elbow]

Oh. You are right. I somehow missed that completely. Well, it is a bit late for this but thank you!

[atomic trail]

Does anyone have a gson Type Adapter example I can see? I found the official one but it doesn't seem too good

[minor summit]

uh, a type adapter for what exactly?

[spring crescent]

Anyone able to help me figure out how to reduce the size of my plugin? I'm currently 17MB, which is obviously too large. I tried using minimizeJAR true but that only dropped it to 16MB

[minor summit]

what are your dependencies

I mean the answer is "use less stuff" but if your core dependency is big, then it's big, you could use proguard I guess to further get rid of stuff but you need to set it up and idk how

[dusky harness]

if you're using 1.17+ then spigot has a libraries feature

https://www.spigotmc.org/threads/spigot-bungeecord-1-17-1-17-1.510208/#post-4184317

you can load libraries on runtime if it's on maven central

[spring crescent]

So I tried running the libraries and changing it to provided here, but the moment I do that, the dependencies stop working.

[atomic trail]

This basically

And yes, lombok is bad ik, pls just ignore it lol

This is what I currently have https://paste.helpch.at/arafuxiqih.java

Just trying to figure out the next step

Is this bad?

        writer.beginObject();
        writer.name("quest");
        JsonObject object = new JsonObject();
        object.add("identifier", JsonParser.parseString(quest.getIdentifier()));
        writer.name(object.getAsString());
        writer.endObject();

For writing the string

[spring crescent]

Is there some magic I need to perform to get my project to point at the libraries?

[minor summit]

uh yes

you'd want to do something like

writer.beginObject();
writer.name("identifier");
writer.value(quest.getIdentifier());
writer.endObject();

although that won't store any other info besides the identifier, usually you'd do something like

writer.beginObject();

writer.name("identifier");
writer.value(quest.getIdentifier());
writer.name("thing");
writer.value(quest.getThing());
writer.name("other thing");
writer.value(quest.otherThing());

writer.endObject();

etc

or just use records, gson handles them naturally

idk if gson has a way to automatically work with hierarchies when deserializing

[atomic trail]

The issue is inheritance. I have a KillQuest class for example that extends Quest, therefore it didn't really work

[atomic trail]

Also shouldn't I have something to actually identify if the reader actually found data for quest. Some sort of identifier for that?

[minor summit]

what

[atomic trail]

When gson goes through the data it has to recognize that it's a Quest somehow right? How do I identify if it actually is a quest?

[minor summit]

gson.fromJson(fileReader, Quest.class)

[atomic trail]

Oh yeah.... I'm dumb lol

[minor summit]

it doesn't have to be a FileReader, but any other source gson can take

[atomic trail]

Thank you! Will try to make this work

[minor summit]

hmm, doesn't seem like it

jackson does

[terse osprey]

I’m sorry Ms. Jackson 😔

[atomic trail]

Kinda proud of this lol https://paste.helpch.at/ucecijobaz.java

I did get a lot of help, but I think it looks good

The null checks might not be optimal but yeah

[spring crescent]

Anyone recommend a dependency management solution/library that works great?

[dusty frost]

what is a "dependency management solution"? lol

like gradle? or like dependency injection?

[spring crescent]

My plugin is 20MB right now due to dependencies and Maven/Gradle ain't about it. I need a way to remotely fetch them. The "Libraries" feature in plugin.yml somehow breaks the dependencies, I guess they aren't loading properly or it can't be found for some unknown reason.

[dusty frost]

oh I mean yeah that's basically as good as it gets

[spring crescent]

I found a fork of Libby which may be perfect

[dusty frost]

or just stop using 20MB of dependencies maybe? lol

[spring crescent]

I'm trying to use Hibernate to model my DB. It's a worthy cause

[dusty frost]

there's no way Hibernate is 20MB

[spring crescent]

Hibernate + Hibernate HikariCP is somehow

rather hibernate-core + hibernate-hikari

[dusty frost]

oh my god hibernate core is 10MB

what the actual fuck lol

just do raw SQL at that point lmao

[spring crescent]

Lol I currently use RAW SQL with a DAO setup, but it's still too messy for my liking

[dusty frost]

is it 20MB messy? lol

[minor summit]

surely not

[spring crescent]

No not that bad, but maintenance is a pain in my butt. Especially maintaining SQL and SQLite it's very "Ewww"

Seems like I don't really have a choice however, I can't even get a dependency solution of any kind to work. Even Libby isn't cutting the cheese properly. Surely theres a reason that the libraries feature isn't working as expected to load the libraries. Do I have to point them at something somehow for them to work, or just include them in the list?

[dusky harness]

what do you have right now?

in build.gradle/pom.xml and plugin.yml

[spring crescent]

pom.xml: https://paste.helpch.at/ibuwacoguz.xml
plugin.yml: https://paste.helpch.at/civebijore.yaml

[spring crescent]

Heres the error I get as well : https://paste.helpch.at/woduyuzubu.md

The class definitely exists at that package location. The moment I direcly use the dependency without libraries suddenly the error disappears.

[dusky harness]

oh hmm
maybe it seems like spigot made it so that the libraries can not access the plugin's classes?? 🤔

- org.hibernate:hibernate-hikaricp:6.4.4.Final
```this one should hopefully work without issues though

idk how big that dependency is

oh nvm its very small

if you're using latest paper, then I think paper-plugins could have something

but I don't really know much about it since I haven't used it myself

https://docs.papermc.io/paper/dev/getting-started/paper-plugins#loaders

[spring crescent]

I am using paper specifically

Hmm

[spring crescent]

Is it possible that I need to add the dependencies, for the dependencies to the libraries list? Like manually enter them all.

[river solstice]

no

[spring crescent]

So just a hot tip, abandoning HibernateORM wasn't a bad idea. Switching to ORMLite was a good idea. Much much much easier to work with and it works great with the libraries feature in plugin.yml. 😄 No more shading/relocating required and my plugin is ultra-lightweight at a very nice 152kb 😄

[spring crescent]

Dude you gotta share some code or something. That question is abysmally generic and very difficult to answer 🤣

I'm guessing, you could parse the placeholder, before giving it to papi, and implement your own functionality for it whenever the placeholder matches a pattern.

[grim oasis]

Did you compile this? @lyric gyro

or did tanguygab do that for you as well?

If you compiled it, then it makes sense to ask for help changing it.

If not, then asking how to edit the code to accept arguments won't do you much good tbh.

And iirc you don't have any experience with java development, so it would make a lot more sense to either: learn at least the basics of java development first OR ask somebody else to do it (maybe tanguygab)

[grim oasis]

This is the same reason I was really confused about your initial question as well

FAQ Answer:

Online Courses:
Online courses are also great for learning java. Some websites that offer them are:

• Coursera - Free unless you want a certificate
• PluralSight - Great courses from what I've seen. Mostly Paid
• Udemy - Never used them myself but they seem to all or at least most be paid.
  My first ever course was one from Coursera. - I can say it was pretty good at introducing me to the programming world as a whole not just java.

Oracle Docs:
Oracle docs can help a lot at learning and understanding java:

• Start with this,
• Breeze through this (skipping stuff that doesn't seem relevant like bitwise operators),
• Hit this.
  They're the first three from this larger thing which you should definitely go through overall. But those three should be enough for slightly better understanding of what is happening here without feeling like a huge time sink.
  That one is a small part of this larger site wherein "Essential Java Classes" and "Collections" also have good useful stuff

Other services:
Some other cool services that will help you learn java are:

• SoloLearn
• W3Schools
• JetBrains Academy

As you can see there are plenty of good ways to learn as long as you're willing to invest the time. Have fun learning!

[grim oasis]

yeah, i like it

you are going to need an IDE to start actually coding, but really have to learn how the language functions first before going into a project

[merry knoll]

vs is fine, but i would go with intellij if your ram allows it

[dense drift]

Imho it is better to get a proper IDE

[merry knoll]

vs is a proper ide, he is not talking about vs code i believe

with plugins it can be, i personally would just go with jetbrains stuff though

[torpid raft]

VS is also a ram hog afaik

if you can run VS you can prolly run IJ

[merry knoll]

anything above 8 and you should be fine with small code bases

[merry knoll]

i feel with latest versions this is not really true anymore, intellij performance has been getting worse i feel

or rather all jetbrains ides feel slower

[spring crescent]

Is it common for updated resouces on Spigot to actually not update? Seems my recent update isn't actually appearing despite uploading it. Sus

[broken elbow]

never had that happen nor did I hear anyone else encounter this issue

Can someone help me make the customMessage variable a clickable text, when sent, and after a staff clicks on the text, it would run a command "gmute playerName" ?

#general-plugins @hearty igloo

[warm steppe]

ignore @spring crescent's message, it is recommended to not use that spigots bloatware. It is better to use https://docs.advntr.dev/text.html

[worn jasper]

stop recommending bad stuff to people lol

[spring crescent]

lol I didn’t know it was bad

There I got rid of scary bad link

[spring crescent]

What is peoples’ aversion to dependencies and third party libraries? I understand sometimes they can be bad but also discovering that can be an amazing learning opportunity. Case in point, I discovered Hibernate is great, but not for plugins. As a result I went and learned ORMLite. Or I discovered IF is better than TriumphGUI, or that ACF is phenomenal. All these things I’ve picked up by trial and error, because I did research and tried different things.

[graceful hedge]

I mean yeah I think its almost always worth trying something before fully judging it

[spring crescent]

If anything for the sole purpose of reminding you that you aren't a 10x dev, and no one is, and that you should just quit now xD

[graceful hedge]

Im probably a 10^-1xdev

:^)

[spring crescent]

I'm a 10eggs developer. I'm a farmer xD

[pulsar ferry]

Hibernate is really nice .. if you're using Spring

[worn jasper]

+1

[terse osprey]

You pretty much hit the nail on the head, it’s like buying a new game that you’re looking forward to playing and running into people who have thousands of hours in the game. They inform you of the statistical best meta and if you’re not playing by that meta you might as well uninstall.
This has plagued MC development spaces since I’ve been in them and I think are the culmination of a couple factors

[dusty frost]

I think another big part of that on the flip side though is that a ton of people try to do MC plugin stuff without Java experience/as a first time learning to program and they can make some really bad code lol

i know i've seen my fair share at least here

[spring crescent]

Maybe I'm just built different. I thoroughly enjoy helping people, and because of that I always have a preconceived notion that everyone else would feel the same. Particalarly in a setting like HelpChat, where the idea is to help xD

[worn jasper]

jokes on you, I have been coding in java for quite some time and my code still sucks

😎

[spring crescent]

^^^^ Refer to the above note about 10x dev xD

[worn jasper]

good, just don't recommend them shitty stuff like spigot's text chat components and we gud

[spring crescent]

How am I to know it's shitty, without first experiencing it. I made no such recommendation, merely posted a link.

I appreciate being called out on it, but there is this thing called "Tact"

[worn jasper]

the correct answer is not posting it at all

😎

anything spigot related = bad

take note

paper 🔛 🔝

[terse osprey]

You’re unhinged

[spring crescent]

facts xD

[worn jasper]

you speak like I know what that means

[spring crescent]

It means, you're deliberately trying to get either #1 an ego boost, or #2 trying to get a rise out of people

[terse osprey]

Then perhaps the correct answer is to not post anything at all 🙂

[spring crescent]

💀

[worn jasper]

more like, 3rd, making sure people don't go down the sh@ hole that spigot is

trying to save ya bud

[spring crescent]

For example, a good response to a perceived shitty post might be to say something like
"I appreciate you're trying to recommend X thing, but X thing is bad, and here's why."

Simply making a blanket statement "Don't recommend shitty stuff" makes others perceive your comment as abrasive, and off putting, degrading any potential for self-growth, for both you and the receiving party.

[worn jasper]

sadly, 80% of people that fall in that hole are unable to be saved, they become spigotolics and their opinions of the holy spigot can't be changed

[worn jasper]

fair point

[spring crescent]

See, growth ❤️

[merry knoll]

man, i love the fact that you have the energy to explain after the response

[worn jasper]

ngl I would not have it

[merry knoll]

but also, anything spigot-chat related is quite bad

[spring crescent]

We're all on a different journey my guy. I don't know it all, and I know I don't xD I can see why he posted that response, and I respect it. Namely because I'm making myself look at it from his perspective. Guaranteed @worn jasper is thinking "Oh god, not another one of these."

[pulsar ferry]

The amount of people in the community that are just plain arrogant is what makes help channels feel shit, specially for newbies
I mean look at stackoverflow as an example

[worn jasper]

hell yeah

[worn jasper]

thanks?

[terse osprey]

I can’t add reaction but fax 📠

[pulsar ferry]

Why are you assuming I'm talking about you? lol

[spring crescent]

Revert to statement #1 ego xD

[worn jasper]

cause I myself agree that I was a bit arrogant

[pulsar ferry]

Yes but that is like a tiny bit of arrogance compared to what you see from others

[worn jasper]

so I would be in that group you mentioned

I mean...

[merry knoll]

duplicate of another question thats not even the same, question closed

[worn jasper]

I have seen worse yes

[spring crescent]

I was this close 👌 to posting a lmgtfy.com link xD

[pulsar ferry]

"Have you even searched?"
"See the docs"
"*downvotes for no reason, refuses to reply and explain why, mark as duplicate*"

[spring crescent]

SO is incredibly toxic. The only time a post doesn't get downvoted/closed is when it's so darned complicated no one can figure it out, then it will go unanswered with a 200+ bounty for months.

By that time, a different solution has been found xD

[dusky harness]

the downvote part especially is annoying to see
especially when I have the same question as the poster 🥲
no comments or anything, just -2 or something

[pulsar ferry]

Ah and let's not mention that they'll immediately block your account for getting just a few downvotes

[spring crescent]

My first SO account was straight up banned

[dusky harness]

👀
I am a proud owner of 31 reputation 😤

Even though I did everything right it doesn't detect the api, does anyone know why?

[dusky harness]

Wdym?

Like what's the error?

If it's just red, reload maven (common issue; intellij should fix it)

Otherwise, please send the error or a screenshot

[sharp orchid]

there is no error. I can't use the API

[dusky harness]

Oh, so it seems to load OK but doesn't work in the code?

[sharp orchid]

yep

[dusky harness]

Hmm
Can you send the full pom.xml?

[sharp orchid]

i'm using gradle

[dusky harness]

Oh lol oops

Can you send the full build gradle?

Not really sure what could be the issue

Also you reloaded gradle right?

I think it's like ctrl shift O or the little gradle icon

[sharp orchid]

fix it

[dusky harness]

Oh also use compileOnly, not implementation

[sharp orchid]

fixed*

[dusky harness]

Oh nice

[dusky harness]

Or else it'll include the placeholder api jar inside your plugin, which might cause problems

[merry knoll]

you are answering your own question there

send the packet to only one player by either handling the entity yourself

or cancelling other packets being sent

to other players

either works

use packetevents

or protocollib

whichever you find easier to deal with

[tight junco]

do any of you know (even if its through paper api) if you can modify the experience drops from blocks being mined specifically

[merry knoll]

couldnt you just cancel and break yourself worst case?

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/block/BlockExpEvent.html @tight junco

found this

[tight junco]

oh thats helpful

[merry knoll]

you can just set it apparently

setExpToDrop(int exp)

on that event

[tight junco]

probably gonna have to blockbreakevent -> playerwhobroke -> buff exp

[merry knoll]

no

you just cast the block break event

[tight junco]

oh

[merry knoll]

wait no, you can just ... setdropexp

on the actual break event

[tight junco]

oh im stupid and blind then

guess i should just quit

tell us what you're doing and what you're getting as a response exactly

[unborn ivy]

does anyone know possible causes of getting a "NoSuchMethodError" error even when I have the required classes and methods in the plugin?

[merry knoll]

you probably did not shade it correctly

check your maven - gradle

[unborn ivy]

this specific project isnt maven, im using a local library and all other methods work fine other than this one method which doesnt make any sense

[sterile hinge]

It’s most likely not on the classpath at runtime

[abstract gate]

my plugin depends on two other plugins, I added them to depend, but how do I compile? I imported the jars to library so I can import and all that but it won't compile

[river solstice]

what

[abstract gate]

when i try to compile it says it cannot find the symbol from the dependency, I added the jars to library

although I don't want to compile with them since they are already plugins in the server

[abstract gate]

actually it specifically says error: package infinitycity.botanischergarten does not exist

[dusky harness]

how?

like what are you using to add the jars to the library?

I'm guessing that you're trying to use 2 different build tools at once (which won't work)

intellij and maven or gradle

[fleet shale]

does anyone here know how to convert an Inventory to an ItemStack[] i have a function to serialize an inventory to base64 and then one to deserialize it to an Inventory but the setContents() requires an ItemStack[] and i cant seem to find any sources using my wording on how to do this

[river solstice]

There is a bunch of information online

This thing has been discussed like a thousand times

[fleet shale]

the keywords ive used must not be the right ones i coudlnt find any

[river solstice]

Cant you just get the contents of the inv?

[fleet shale]

the contents of the players inv are gotten and serialized to a string then saved as a pdc im trying to now reverse that and set the players inv contents to the contents gotten back from the pdcstring

[worn jasper]

getContents() returns ItemStack[]

[fleet shale]

if(cmd.getName().equalsIgnoreCase("deserialize") && sender instanceof Player) {
            Player player = (Player) sender;
            String inventory = getpdc(player, "inventory");
            Inventory inv;
            try {
                inv = deserializeInventory(inventory);
            } catch (IOException e) {
                throw new RuntimeException(e);
            }
            //here is where i want to set the players inventory to the contents gotten from inv
        }

[worn jasper]

instead of serializing the inventory to base64, serialize the contents

[worn jasper]

or if you want to stay with saving inventory, ^^ does the trick

[fleet shale]

im not really sure how to do this im new to the whole inventory stuff right now im using the methods from this gist
https://gist.github.com/graywolf336/8153678

[worn jasper]

how new are you to it?

[fleet shale]

essentially my main goal here is save the inventory to the string that is then saved to the players pdc then when i run a command it takes the string back deserializes it then sets their inventory back to the contents gotten from the deserialization

[fleet shale]

i just started learning it a few hours ago

[worn jasper]

inventories or bukkit itself?

[fleet shale]

inventories ive been developing with bukkit for a couple months now this is my fourth plugin

[worn jasper]

well I just told you, you can't simply override the inventory object of a player (I think), just set the contents of it, and save the contents instead of the inventory.

[fleet shale]

-setpdc(player,"inventory",serializeInventory(player.getInventory().getContents()));
      -requires Inventory
      -given ItemStack[]

[worn jasper]

?

what's the issue, I am confused

[fleet shale]

requires an Inventory but getContents() gives an ItemStack[]

basically this requires an inventory not an itemstack

[worn jasper]

ok, and?

just use getInventory()?

[fleet shale]

so setContents() cannot be used i have no choice but to use Inventory my issue still is that i cant update the players inv or set contents of the inv without a way of using the Inventory type to do this somehow

[worn jasper]

you can use it

just use getContents() from the inventory you saved

quite confused on what's so hard?

[fleet shale]

omg i didnt even think of that let me try that

[worn jasper]

Best way is to just save the contents instead of the whole inventory as said before

[fleet shale]

be easy on me i just taught myself java like two months ago lol

[worn jasper]

that sounds scary but gl on that

I would also def. only use things you understand, helped me to learn

aka only use the above method if you actually understand how it works

[fleet shale]

so i did that using this line player.getInventory().setContents(inv.getContents()); but got an error and the error log it too big to post here but something clearly went wrong

but it returns im pretty sure a nul pointer exception

[fleet shale]

https://paste.helpch.at/efejasozul.rb

this is the relevent line to the error
Caused by: java.lang.IllegalArgumentException: Size for custom inventory must be a multiple of 9 between 9 and 54 slots (got 41)

im assuming the issue is that this includes armor slots in the serialization of the inventory but im not too sure how id work around that

but where the return is less than the expected 54 slots that doesnt seem the issue if im thinkign this right so im unsure of this issue or whats causing it

[worn jasper]

by learning how serialization works and creating your own method

[fleet shale]

a little assistance in getting further in this would be more helpful than dismissing it, after all how can one learn without the learning part

[abstract gate]

no it's just the library is not added to the build.gradle while the IDE can see the library because I added it

[dusky harness]

you can't use intellij artifacts and gradle at the same time

[fleet shale]

is there a method to make a player drop all slots of their inventory? or do i have to make some crazy for loop to cycle through each slot and drop the item somehow

[worn jasper]

2. option

[fleet shale]

hmmm ok

[torpid raft]

craAAAazy for loop 🤪🥴

[fleet shale]

can someone elighten me on a method that can be used to drop an item from an inventory slot

[dense drift]

World#dropItem

[terse osprey]

You hit the nail on the head already, for loop over the players inv and armor contents, clone and drop them at the players location and then delete them from the inv

[fleet shale]

ohhhh thats very helpful i didnt think i had to use the clone part this may make this much easier

[terse osprey]

You might not have to, you might be able to just drop the itemstack themselves and then delete the inv contents, test both ways if you wish

[fleet shale]

so this may be all wrong but im hoping im on the right track here ```java
public void dropInv(Player player) {
int invsize = player.getInventory().getSize();
ItemStack[] itms = player.getInventory().getContents();
for(int i = 0; i < invsize; i++) {
itms[i].clone();
}
}

[terse osprey]

for(ItemStack is : player.getInventory.getContents())

[fleet shale]

so this?

public void dropInv(Player player) {
            for(ItemStack is : player.getInventory().getContents()) {
                is.clone();
            }
        }

assuming no since this gives an error when attempting

[terse osprey]

Check that the is isn’t null, if(is != null) {

Otherwise you’re cloning air as well lol

[fleet shale]

probably a dumb question but when doing this null check can i use```java
if(is = null) { continue; }

or should i just use a ```java
if(is != null) { the stuff }

[terse osprey]

If you use continue the for loop will instantly move onto the next iteration in the loop, just use the 2nd one

[fleet shale]

ahh ok i have only use a contiue once so i wasnt 100% on what it did

ok that passed no errors buttt nothing dropped

did i miss a step

[terse osprey]

Continue moves onto next iteration and break will break the loop and move onto other code in the method

Send the code

[fleet shale]

public void dropInv(Player player) {
            for(ItemStack is : player.getInventory().getContents()) {
                if (is != null) {
                    is.clone();
                }
            }
        }

[terse osprey]

So all you’re doing there is cloning the itemstack you’re not actually dropping it

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/World.html

[fleet shale]

oop ok so another probably dumb question but whats the method to drop the item and or put that item in the world (not allowing it to get picked up immediately)

or is that world#dropitem

[terse osprey]

Look for the World#dropItem

Yup

[fleet shale]

its probably in that jdoc but is there a way to prevent instantanious pickup

[terse osprey]

You’ll have to pass a location in as well as the itemstack itself

[fleet shale]

id want that to be directly infront of the player but im not sure if this is right but i can take the location and setX/Y/Z to +2 right?

[terse osprey]

Providing you know which way (x or z) to increase you can just player.getLocation().add(2, 0, 0) in the case of increasing the x cord

[fleet shale]

ik theres a method for facing direction ive used with vectors but figuring that out seems overly complicated

[terse osprey]

If you want the drop to be exactly in front of the player I’m sure people smarter than me have answered that on the spigot forums or I’m sure somebody here can help you with that, I’ve never attempted to drop based on vectors so don’t wanna lead you astray lol

[fleet shale]

haha thats ok your help was the most help ive actually recieved here so far haha the final void ive come up with is this ```java
public void dropInv(Player player) {
String world = player.getWorld().getName();
Location ploc = player.getLocation().add(2, 0, 0);
for(ItemStack is : player.getInventory().getContents()) {
if (is != null) {
is.clone();
Bukkit.getServer().getWorld(world).dropItem(ploc, is);
player.playEffect(ploc, Effect.TRIAL_SPAWNER_DETECT_PLAYER, 10);
}
}
}

ik some of my methods are kinda strewn in their efficiency but it works for me and helps me understand it haha

[worn jasper]

dies

me go sleep

[terse osprey]

Some things I’d change

1. You don’t need to get a string of the world, you can just get the world itself with player.getWorld()
2. You don’t have to clone the itemstack with this method so you can get rid of that
3. If you have the world you don’t have to use Bukkit.getServer().getWorld because we already have it so you can just do world.dropItem
4. If you want to add the pickup delay you can use Item item = world.dropItem(pLoc, is) to create an item object and use .setPickupDelay() to set the delay as shown here https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Item.html

Other than that gj

[abstract gate]

so how do i add the dependency?

[fleet shale]

can anyone tell me what would cause this to run as many times as there are players online i cant seem to figure it out

public void onInteract(PlayerInteractEvent event) {
        Player player = (Player) event.getPlayer();
        if(Objects.equals(getpdc(player,"zoomable"),"true")) {
            if (player.getInventory().getItemInHand().getType() == Material.BLAZE_ROD && player.getItemInHand().getItemMeta().getDisplayName().equals("Zoom")) {
                if (event.getAction() == Action.RIGHT_CLICK_AIR) {
                    //player.sendMessage(ChatColor.BOLD + "DE TEST WERKT!");
                        zoom(player);
                }
                if (player.getInventory().getItemInOffHand().getType() == Material.BLAZE_ROD && player.getItemInHand().getItemMeta().getDisplayName().equals("Zoom")) {
                    if (event.getAction() == Action.RIGHT_CLICK_AIR) {
                        //player.sendMessage(ChatColor.BOLD + "DE TEST WERKT!");
                        zoom(player);
                    }
                }

            }
            if(Objects.equals(getpdc(player,"launching"),"true")) {
                event.setCancelled(true);
            }
        }
        if(Objects.equals(getpdc(player, "jailed"), "true")) {
            event.setCancelled(true);
        } else {
            event.setCancelled(false);
        }
    }

for example the zoom function runs once to the player who is holding the Zoom blaze rod and right clicks air (as its meant to) but if a second player joins every time i click with the zoom stick it then 'zooms' me twice and so on for every additional number of players that join, i may have missed some discrepancy in the code event but i cant seem to see it

[fleet shale]

stupid question but would i replace itemInHand with gethand? or does this need a whole now loop?

[terse osprey]

No you don’t have to replace it just surround the code with the hand check, basically anytime a player interacts they technically do it twice (one for each hand) if you don’t want this to happen just check if the interaction hand is the main hand

[grim oasis]

it looks like there is a hand check to me

ah, but the if statements aren't correct

the check for the offhand is INSIDE the check for the main hand

ahhhh even more

the "offhand" check, checks the meta for the mainhand item
player.getInventory().getItemInOffHand().getType() == Material.BLAZE_ROD && player.getItemInHand().getItemMeta().getDisplayName().equals("Zoom")

@fleet shale

i still have no idea about the weird phenomenon you're getting with the once per player thing, but that's what I've noticed in the method so far

and since I'm giving input, I would check if the action is right click air first, then check the mainhand, else check offhand

then you don't have 2 if statements for the action, you just have 1

optimizes a bit

[fleet shale]

i removed the offhand check so no worries about that

 Player player = (Player) event.getPlayer();
        if(Objects.equals(getpdc(player,"zoomable"),"true")) {
            if (player.getInventory().getItemInHand().getType() == Material.BLAZE_ROD && player.getItemInHand().getItemMeta().getDisplayName().equals("Zoom")) {
                if (event.getAction() == Action.RIGHT_CLICK_AIR) {
                        zoom(player);
                }

            }
            if(Objects.equals(getpdc(player,"launching"),"true")) {
                event.setCancelled(true);
            }
        }

this is all it has right now but still gets the per player zoom

[grim oasis]

can you share the entire class?

or at least the zoom method?

recommend skunity for better skript support

or even better recommendation, stop using it

Are we banning Lua?
No, all that is totally fine to be asked here
Ofc doesn't mean people will help, I don't think there is anyone that is active here that uses Skript

And as for you, you do not need to be rude to people just because you don't like what they use, if you don't want to help then don't reply

[dusky harness]

Oh true

Okaaaay

Sorry I just forgot since I feel like that's what's been said every time someone tries asking for skript help here

And since the word "development" is ambiguous, I just assumed it wasn't for skripting

Mb

[worn jasper]

If I were to be rude I would straight away say skript sucks and not provide anything else. Instead, I provided a better place to ask (Skunity, since here is very rare to get skript help like you said) and then proceeded to provide my own personal recommendation, which is stopping to use it.

[warm steppe]

developing isnt scripting soooooooo idkkkk

alsooo

[pulsar ferry]

If you were to be ruder*, doesn't mean you message wasn't rude

[worn jasper]

On a side note, Skript scripting do be just english writing at this point lol

[pulsar ferry]

Scripting is not configuration either

[pulsar ferry]

So is SQL, what is your point?

[worn jasper]

debatable to be fair. But point is that saying using skript is "coding" only sends the wrong message, which in turn is what creates skript kiddies that ruin the community even more because their holy mighty skript is the best and proceed to put in their CV they can "code" lol.

What is and isn't a programming language is very debatable nowadays, for instance, the whole HTML and CSS being programming languages or not.

Same thing, some think so, others don't.

The real question is, at the end of the day, does putting that down on your CV help in any shape or form? In html/css's case, yes, in skript? Hell no.

So, excuse me if I don't say "OH skript, skript is sooo good, think skunity is better for support than here, I totally recommend using skript though!"

[pulsar ferry]

I have never mentioned it being "coding", this channel isn't just "coding"
How is CV even being brought up? You are acting like this channel is some sort of professional coding help lol
Skript is totally fine to be helped here, if anyone is whiling to help
You do not need to recommend, you can just ignore
Anyways, end of argument, this argument is more out of topic in this channel than the subject of the argument

[worn jasper]

But at one point, you get tired of the skript guys thinking that their whole "programming language" is the holy god of the gods and better than java and whatever nonsense those people say, if I have the chance to "save" (my words for it) someone from skript, I sure as hell will try to do so.

(Also, CV was just a random example that came to my mind)

[minor summit]

just a few people asking for help with skript every now and again does not mean they think it's "the holy god of the gods and better than java"

it's people that just need help with something to get it done, if you don't wanna help then don't

Anyone have any thoughts on a "Structure" or "Totem" that is configured in a config, and how can I reasonably track said totem, and do X thing upon completion. For example I might want to have a structure that is in the shape of a "t" 4 blocks tall, three wide, made of specific blocks. Is there a reliable and performant way of tracking that structure to see if it has been constructed and triggering an action based on it?

I was thinking of using pre-determined "X, Y, Z" for each of the blocks' positions using an object to "map" the structure of that object, but still not entirely certain it would work all that well.

how do i modifiy them

afaik you have to remove them and make a new one to update the delay

you get the id when you first schedule a task so store that for if you need to delete it

you can create a map of task ids, and call a method to delete and then re-schedule a task as needed yes

please anyone 😩
ive searched everywhere to try and fix

omg i fixed it

when i created the table i also made the primary key, which by default H2 makes uppercase

then i pre-made the columns, which i accidentally made a duplicate of the primary key except lowercase

so when i tried setting/adding row, it couldnt bc it didnt set primary target column 🙃

adding backticks around primary key name and removing duplicate column creation fixed it

oh jk looks like its just cause everything is uppercase now which i dont want

[dark garnet]

alright fixed lowercase issue, added IGNORECASE=TRUE to my connection URL and made sure everything was enclosed with double quotes (")

oh didnt need to have IGNORECASE=TRUE, guess i wont be keeping that lol

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

[hoary scarab]

Which part?

[hazy vale]

idk it doesn't let me save

[hoary scarab]

Try config = config.save(file);

[hazy vale]

i also have its child

public class Warps extends YamlManager {
    public Warps(Main main) {
        super(main,"Warps.yml");
    }
    public void newWarp(String name, Player owner) {
        System.out.println("works!");
    }
}

[hoary scarab]

Also if you initialize main already whats the point in passing it?
protected Main main = Main.getInstance();
YamlManager(Main main, String fileName) {

[hazy vale]

could you explain what super() is?

[hoary scarab]

super basically grabs from the parent class... "super" class.

[hazy vale]

so if i call super()
in a class that extends YamlManager it will run

public YamlManager(Main main, String fileName) {
        this.file = new File(main.getDataFolder(),fileName);
        if(!file.exists()) {
            try {
                file.createNewFile();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        this.config = YamlConfiguration.loadConfiguration(file);
    }

this right?

[hoary scarab]

Based on your code above, Passing main to that constructor isn't needed.

[hazy vale]

i know

[hoary scarab]

Sorry didn't read the first line. Yes a class that extends that class should call that constructor when super is used.

[hazy vale]

so its like doing this:
manager = YamlManager(stuff)

[hoary scarab]

new YamlManager() yes

[hazy vale]

oh sry yeah

thx

int limitedVictimKillStreak = Math.min(victimKillStreak, 5);

String coloredVictimKillStreak = victimKillStreakColor + String.valueOf(limitedVictimKillStreak);

[atomic trail]

Will this also exclude it from the publishing?

[atomic trail]

That worked ty, not sure about publishing tho

[dusky harness]

wdym?

are you publishing that to a maven repository?

[atomic trail]

I'm publishing the project to a maven repository yeah, but I don't want to publish the empty root ofc

[dusky harness]

been a while since I've set it up, but I think as long as you don't create the publishing configuration for the root it should be fine

[atomic trail]

Hmmm it needs this for some reason

[dusky harness]

can u show build.gradle(.kts)?

[atomic trail]

Ye

Here https://paste.helpch.at/fasoniveci.php

[dusky harness]

ur publishing is trying to get it from only root module

i think

in line 107

[atomic trail]

Yeah, this is the publishing function or whatever I use for my projects without subprojects, just not really sure how to change it

To exclude root

[dusky harness]

try putting that in the subprojects as well (excluding common)

[atomic trail]

Could not PUT 'https://maven.summitrealms.com/private/com/summitrealms/summitlibs/common/1.0.0-SNAPSHOT/common-1.0.0-20240323.225241-2-all.jar'. Received status code 413 from server: Payload Too Large

It's like 1.5mb and shouldn't be too large

I think it's adding more than it should

Trying to run scan

https://scans.gradle.com/s/6kjjpk6jgy5wi

[dusky harness]

try excluding common module

since it seems to work for bukkit

[atomic trail]

How?

[dusky harness]

if (project.name != "common") { publishing { ...

inside the subprojects {}

[atomic trail]

Ah yeah ofc

That does seem to work

It might just be the repo settings then

1.5mb limit just seems so low

[dusky harness]

interesting
idk what the cause is but if it works, that's all that matters :)))

[dusky harness]

I'm assuming bukkit & velocity would be shading common tho, meaning both would be bigger than common

[atomic trail]

Do you know if it's possible to publish in a queue sort of? So it's not all in one request

[dusky harness]

wdym?

currently, it should be doing that

bukkit -> velocity (ig gradle likes to go alphabetical)

[atomic trail]

So the "Payload" isnt too large is what I mean

Or well to make it smaller at least

Right now it's one big payload I assume

[atomic trail]

Under 1 payload tho right?

[dusky harness]

i think 2
because the tasks are registered under each submodule
so it runs the tasks in both submodules separately

[atomic trail]

Would make sense yeah

What's the general structure for usage, should the bukkit module implement the common module as a dependency?

Or should whoever uses the library implement both

[dusky harness]

tbh I'm not sure here
usually, libraries/apis shouldn't be shading though
didn't say anything earlier since I don't have much knowledge about this

[atomic trail]

Ah alright, thanks for all the help tho :))

I'll look into some open sourced projects to check this

Oh they use this thing

dependencies {
    api("")
}

Never seen it before

[dusky harness]

api or the api("")?

[atomic trail]

api

They have something in the quotes ofc but yeah

[dusky harness]

ah that's like shading but not

it shades when ppl use your library

but your library jar doesn't actually shade it

[royal hedge]

Why are you publishing a shaded build

[atomic trail]

I'm not sure if I should shade it or how it should be setup

I just have a sub project called "bukkit" that needs functionality from "common"

[atomic trail]

What's the difference then? the core can't be used inside the project?

[dusky harness]

the difference is that it allows the project using your library to manage it
ex they can exclude it if needed

however, you can't api the common module because it's not published

so either
a) shade it
b) publish common
which is better? probably b, but I don't have any examples to prove

[atomic trail]

The common module will be published tho I think

Or is that bad practice?

[dusky harness]

¯_(ツ)_/¯

I'm pretty sure publishing shaded builds is bad practice though as Sparky implied

[atomic trail]

Would that also include publishing builds using api dependencies? As it shades but doesnt or whatever lol

Just using this as example https://github.com/SpongePowered/Configurate/blob/master/format/yaml/build.gradle

[dusky harness]

no, because for api, the project is aware of that and can control it
for shading, it's as if everything is in 1 (bc it is), preventing any control

there's probably other reasons besides that

[atomic trail]

What happens if someone using the library implements both bukkit and common then?

It would have 2 copies of common right?

Or well graddle would handle that in some way, but probably not optimal?

[dusky harness]

hmm, not sure how gradle would handle it

but using api prevents that conflict because gradle can just choose the higher version or smth (idk what gradle does)
or the user can exclude one version

[atomic trail]

Found this

If you are a library mantainer you should use api for every dependency which is needed for the public API of your library, while use implementation for test dependencies or dependencies which must not be used by the final users.

Basically what u said yeah

[dusky harness]

also note that you don't need shadow to use implementation

I'm pretty sure

in the library
because as long as the project using your library has shadow, it'll work
although if you want to relocate something, ig you'll need shadow (as the configurate example above has)

[atomic trail]

Honestly not even sure when to use shadow, I never really understood it, I just always add it lol

Okay so the api thing makes kinda sense, but why would you give the library user the option to not use the common module? As it's required to run the program

[royal hedge]

api is the same as implementation but your consumers get access to the dependency too

its unrelated to publishing

just publish your core or whatever and dont shade

shading causes conflicts

[atomic trail]

How do I avoid shading though?

[royal hedge]

by removing shadow?

[atomic trail]

oh lol

I should probably look into how shading exactly works

But I never understand why it's used

[dusty frost]

It's used to copy + paste the compiled code of libraries into your .jar file

[royal hedge]

basically building ur project just compiles ur own code, not dependencies

[dusty frost]

If you don't have access to them another way, you basically need to shade them to get access

[royal hedge]

so when u shade it compiles it and includes the dependencies

[royal hedge]

^

[dusty frost]

Otherwise you can use like the Spigot library loader, or like Spigot could maybe include it and expose it to you directly

[atomic trail]

Ohhh so shadow just adds all implemented dependencies to the jar?

[dusty frost]

yes

[royal hedge]

yes

[atomic trail]

Ah makes sense

but what's the difference between implementation and compileOnly if implementation doesn't add the dependencies to the jar?

I thought that was what its for

[dusty frost]

compileOnly means dependencies that you only need for compile time, implementation is dependencies you need always

shadow is just a way of obtaining those implemented dependencies

[dusky harness]

also - while Star and Sparky are here, would this mean that it's better to publish the common module as well?
otherwise, shading would be needed

[atomic trail]

But what's the functionality difference if it's not added to runtime anyway?

[royal hedge]

defeinitely

[atomic trail]

Without shadow ofc

[dusky harness]

alr

[dusty frost]

I don't know if there is really a functional difference lol, I just know that's how it's setup

I think gradle and maven just provide ways to declare where dependencies should be available but don't actually technically do anything about it

[atomic trail]

Ah gotcha

[dusty frost]

maven is kind of the opposite way, where you have to add <scope>provided</scope> to have it not shade stuff iirc

but similar vibes, declarative dependency managers, etc.

[atomic trail]

Then the difference between implementation and api doesn't make any sense to me, if I'm not using shadowjar

[dusty frost]

Well I think the idea is that there are other ways to provide dependencies

[royal hedge]

if ur just building regularly it doesnt do anything differently, but (i think) if u run it with like the like the application plugin, in tests, or use shadow theyll provide the dependencies (whether they add them to the runtime classpath or include them in the jar)

[dusty frost]

Like not just shadowjar

[dusky harness]

implementation = hidden
api = not hidden

in code

when editing in build.gradle.kts, everything is shown & editable

except when shading

[atomic trail]

Yeah, but does making it not hidden change any functionality for the consumer of the library? Other than the fact they can see it?

[dusky harness]

the change is functionality is the fact that they can or can't see it

it'll always be in the final jar, but api will be accessible in code while implementation won't

[royal hedge]

basically

project :a

dependencies {
  implementation("paper here")
}

project :dependant

// build gradle
dependencies {
  implementation(project(":a"))
}

// java file
import org.bukkit.inventory.ItemStack; // error, cannot access

but if we change

  implementation("paper here")

to

  api("paper here")

then it will automatically get added to :dependant when they depend on :a and there wont be an error

[atomic trail]

Why not just make everything not hidden then? Too much unusable information?

[dusky harness]

see above :))
(and just ignore that you're not supposed to be shading paper)

[dusty frost]

Same reason you don't publish every method and class in a Java project

hide implementation details, so you can change them

[atomic trail]

Ohhhhh

That makes good sense yeah

[dusty frost]

for instance, if a library that depends on you also depends on your version of like, say, HikariCP, and then you upgrade, it'll break their code

[dusky harness]

ohhh also i misread ur message

oops

i thought you said why not make everything hidden

but I think it's basically what Star said - the same (or similar) reason why visibility modifiers exist in java

[atomic trail]

Ahhhhh gotcha, and still keep backwards compatiblity right?

[dusty frost]

Exactly

[royal hedge]

yea its a terrible example

[dusky harness]

no its good

[atomic trail]

That actually makes a lot of sense

[royal hedge]

no like in terms or real world ness

[atomic trail]

So api is basically "public" in java and implementation is "private"

[dusky harness]

yeah

[atomic trail]

That's very oversimplified ofc but the concept ig

[dusky harness]

still there, just hidden

[atomic trail]

Gotcha

Thanks everyone!

I always learn so much when I ask in here hahah

[atomic trail]

Project with path 'common' could not be found in project ':bukkit'.

Should it maybe be in root subProjects instead?

[dusky harness]

try :common

[atomic trail]

I forgot I can just use rootProject().project("whaever")

[atomic trail]

Is it possible to exclude specific dependencies from shadowJar?

[dusty frost]

yeah mark them as compileOnly

[atomic trail]

This just seems wrong setup

They're so big because they have the common as api dependency

Common:

    api("org.spongepowered:configurate-core:4.2.0-SNAPSHOT")
    api("org.spongepowered:configurate-yaml:4.2.0-SNAPSHOT")
    api("org.spongepowered:configurate-gson:4.2.0-SNAPSHOT")

sub projects:

    dependencies {
        if(project.name != "common") {
            api(rootProject.project("common"))
        }
    }

Does this seem right?

[royal hedge]

The size of common womt change the size of velo and bukkit unless ur shading

[atomic trail]

Using api will shade it tho right?

[royal hedge]

Anything on the runtime classpath will be dhaded by shadow

[dusty frost]

so I'm confused, surely you want to be shading Configurate since it's not provided by anything?

[royal hedge]

But u shouldnt use shadow if u dont wanna shade

[royal hedge]

Usually u want ur consumers to be shading

[dusty frost]

or if this is a multimodule project, the Bukkit and Velocity ones should use compileOnly instead of api, since they're just consuming it from your other plugin

[dusty frost]

Usually the opposite lol

You want providers to be shading and providing it to other stuff, and the consumers just link to it in the classpath at runtime

[atomic trail]

Yeah, it’s a custom fork for Configurate, so can’t use the version in papermc jar

[dusty frost]

Ah okay yeah

[atomic trail]

I need shadow for other dependencies tho

[dusty frost]

So, you intend for people to have the Common jar plus either Bukkit or Velocity depending on which platform?

like on a Paper server, for instance, they should have the Common jar and the Bukkit jar?

[atomic trail]

That’s what I’m not sure about, what’s best practice?

[dusty frost]

Best practice is just to have one jar per platform

and just basically include all the common in it

[royal hedge]

This is a library tho? Not a plugin

[atomic trail]

Yeah, so common should probably not even be published then, and just internal

[royal hedge]

Unless im misunderstanding

[dusty frost]

Looks like both lol

A common "library" and two plugins, one for Bukkit and one for Velocity

[atomic trail]

Wait wtf am I doing lol

I’m tired
