[lost matrix]

Show some code pls. Comparing the distance between two colors can be done via an N-dimensional vector (3 without and 4 with alpha)

[storm crystal]

is this correct to do something to each entity that's been scanned

or did I do this wrong as well

[grim hound]

It's like watching a gore video and discovering how much you can bend the human body

[glad prawn]

https://docs.oracle.com/javase/tutorial/java/javaOO/anonymousclasses.html#declaring-anonymous-classes this

[rotund ravine]

@storm crystal That’s a fine loop

[prisma sedge]

Yeah about that, there is no code to show, the code I have doesn't work

[rotund ravine]

Yeah anonymous classes sure

[grim hound]

Like you don't even think about it

[prisma sedge]

I can't figure out a way to compare them at all

[rotund ravine]

Show us anyway

Just show us where you are at

[prisma sedge]

alright

        int PURPLE_R = 150;
        int PURPLE_G = 80;
        int PURPLE_B = 150;
        int TOLERANCE = 60;
        return (PURPLE_R - TOLERANCE < color.getRed() && color.getRed() < PURPLE_R + TOLERANCE) &&
                (PURPLE_G - TOLERANCE < color.getGreen() && color.getGreen() < PURPLE_G + TOLERANCE) &&
                (PURPLE_B - TOLERANCE < color.getBlue() && color.getBlue() < PURPLE_B + TOLERANCE);
    }```

[rotund ravine]

Maybe name the entity variable smth else

[grim hound]

Maybe the mustache guy was right

[prisma sedge]

I know it's not polished I just need it to work atm

[grim hound]

Cuz what the hell

[rotund ravine]

There is probably some fine examples on this https://stackoverflow.com/questions/15262258/how-could-i-compare-colors-in-java

[lost matrix]

RGB is not a good color space to check for color differences if you aim for perceived difference for humans.

[rotund ravine]

I am alien

[storm crystal]

can I just do this

since Im not using i at all and just refer to living entity

[prisma sedge]

I tried the solution they had, it didn't work very well.

[lost matrix]

Looks better

[prisma sedge]

I tried messing with the tolerance and everything but nope

[rotund ravine]

Just call i entity and it looks even better

[lost matrix]

Let me get my computer vision script out real quick. We had a nice method for comparing perceived color distances.

[rotund ravine]

https://stackoverflow.com/questions/9018016/how-to-compare-two-colors-for-similarity-difference

More different ways to compare

[compact haven]

ive put classes inside of methods before

in kotlin

[prisma sedge]

Like a anonymous inner class?

[compact haven]

nope

[rotund ravine]

Sounds dumb

[compact haven]

nah nah watch

[storm crystal]

how do sound and category look like, whats the base volume and pitch for sound effects?

[rotund ravine]

Probably 1 and 1

[grim hound]

Mental asylums couldn't handle you, that's why you're out

[rotund ravine]

If you google it you can find plenty of examples I am sure

[compact haven]

fun onCreate(ctx: Context) {
  class CreateResponse(val something: Int)
  
  ...

  val response = CreateResponse(15)
  ctx.respondJson(response)
}

[rotund ravine]

Ah

[grim hound]

Man just make it outside or use many variables

[compact haven]

I trick gson into serializing it without exposing needless classes that arent use outside the rest handler

[grim hound]

Like why

Why

[compact haven]

because I decided to

that's why

[grim hound]

Oh

Well I guess

[compact haven]

now to be fair, that is pretty bad. I would actually abstract the Requests and Responses into a separate dependency, so it can be made part of a lib that calls the rest api as well

then it can also be unit & integration tested without duplicate code

but if you're not doing that, then it's great

[prisma sedge]

@lost matrix I just noticed that it was because my tolerance was too high

sorry but all is well

[dry hazel]

it's not as crazy as it sounds, off the top of my head, local classes are useful for making a thread-safe singleton easily for example

[lost matrix]

Untested code. Let me know if this works.

  public double calculatePerceivedDifference(Color from, Color to) {
    float[] fromYuv = new float[3];
    float[] toYuv = new float[3];
    ColorSpace colorSpace = ColorSpace.getInstance(ColorSpace.TYPE_YCbCr);
    from.getComponents(colorSpace, fromYuv);
    to.getComponents(colorSpace, toYuv);
    float dx = fromYuv[0] - toYuv[0];
    float dy = fromYuv[1] - toYuv[1];
    float dz = fromYuv[2] - toYuv[2];
    return Math.sqrt(dx * dx + dy * dy + dz * dz);
  }

• YUV color space btw

[prisma sedge]

ok I'll see if it works rq

[lost matrix]

PS: there was a * missing

[prisma sedge]

well if it works better.

where?

[glad prawn]

dy +

[prisma sedge]

oh

so this returns a percent?

[storm crystal]

is this a proper way of catching if player is interacting with nothing and then just ignore the rest?

[lost matrix]

A euclidian distance between two vectors in a color space.
So max would be... 2.0 i guess

[lost matrix]

Nope

[umbral ridge]

Made it like so

[lost matrix]

You should never catch a NullpointerException in java

[prisma sedge]

ok well it's throwing a Unknown color space error atm, but I'm just going to use what I have no because it seems to be working fine

[inland apex]

I'm trying to create a 1.8.9 spigot plugin using the IntelliJ "Minecraft Development" plugin but it only goes down to 1.12 how do i change that

[rotund ravine]

No

[prisma sedge]

thanks for the help though

[storm crystal]

why

[umbral ridge]

Forgot the ! 🤓

[lost matrix]

Time machine

[rotund ravine]

@storm crystal If they have nothing in their hand right?

[inland apex]

...

[rotund ravine]

That’s what ur going for?

[lost matrix]

But just let the plugin create a 1.12 project and change the version in your pom.xml

[inland apex]

nah but fr

[rotund ravine]

You don’t

[inland apex]

kk

[rotund ravine]

Smh

1.8.9 should just die

It has lived long enough

[lost matrix]

This might throw some nasty exceptions. Should be fine i guess (?)

[rotund ravine]

We don’t want it anymore

[storm crystal]

yes?

and that doesnt give me any errors

[rotund ravine]

Then check if it’s null or air

[lost matrix]

Your IDE tells you that there might be something wrong with your code by underlining it with yellow lines.
This should be fixed if you want your code to run without problems.

[rotund ravine]

We don’t want exceptions to be thrown is probably the easiest way to explain it

[umbral ridge]

Yea xD

[storm crystal]

thats literally why I decided to remove interacting with nullpointerexception

[rotund ravine]

Don’t get it if it can produce a nullpointer

Before checking first

[quaint mantle]

It can be null if player in login state. i think.

[rotund ravine]

if (item == null || !item.hasItemMeta()) it’s probably air

Woops

[quaint mantle]

Bruh this is itemstack

[rotund ravine]

Yes

[lost matrix]

You can calculate the YUV by hand as well. In case you want that still.

[rotund ravine]

Don’t trust itemstacks to not be null

Also

Also itemmeta will always be null on air

[lost matrix]

Makes it really easy to check for euclidian distance of your colors

[storm crystal]

what does this mean

[rotund ravine]

It means it’s old

player has two hands

[lost matrix]

https://www.spigotmc.org/threads/beginners-guide-to-itemstacks.623654/
This might help

[lost matrix]

Deprecated methods are candidates for removal and should not be used.
There are always alternatives if a method gets deprecated in Spigot.
(Aside from two or so exceptions to this rule)

[storm crystal]

so how do I get player's item in hand

right hand

[rotund ravine]

It’s called the main hand

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[lost matrix]

Player#getInventory() -> PlayerInventory
PlayerInventory#getItemInMainHand() -> ItemStack

[storm crystal]

how do I check if it returns an empty collection

[lost matrix]

Collection<T>#isEmpty() -> boolean

[storm crystal]

whats ->

[lost matrix]

return type

[rotund ravine]

You know

If you went through some basics in a java programming course. That’d be super duper cool

[glad prawn]

l-learnj

[storm crystal]

You know

last time I checked it's not a strict requirement to pass some kind of exam to be allowed to type here

[rotund ravine]

It’s not. It’s just painful to see you making very basic mistakes that could easily be rectified if you spent an hour or two learning via a course.

[storm crystal]

Why do you care

its my problem

[lost matrix]

Yeah but it is a little bit rude if you didnt put in a bit of your time into getting the basics done to be honest

[rotund ravine]

We’re not always nice and helpful, so please do take your time in getting some basics down. We do not expect you to know everything, nor should you really cause we don’t. Just like general layout of the language as well as general conventions would be a major improvement in your efficiency.

[rotund ravine]

Need more code to answer

Wait i don’t

[rotund ravine]

Alright it’s marked ss notnull

Right after the getItem line. Put “if (!item.hasItemMeta()) return;”

Also what is getType telling you?

[lost matrix]

Checking objects if they are null after using them is not useful

[storm crystal]

thats literally what I did?

where did I use it

[rotund ravine]

After

Which is not useful

[storm crystal]

same problems

getting nullpointerexception all the time

[rotund ravine]

That’s not after, but before

[storm crystal]

pretty funny since using try and catch actually removes that problem

[storm crystal]

im not using it to anything yet Im just declaring it

[rotund ravine]

You are using it

[lost matrix]

Yeah. Then just try catch with general Exception
This removes all problems

[rotund ravine]

Sry it’s not marked as notnull i see i see

[rotund ravine]

You just gotta move the pieces you already have here around

[lost matrix]

You are calling getType() on your item
But if item is null at that point, then you get a NullpointerException.

[prisma raft]

ItemStack item <- declares the item variable
item.getType() <- takes the object referenced by the item variable and attempts to call its getType() method. This will throw a runtime error if item is null, because null objects can't have methods called on them

you would want to check if it's null after declaring it but before using it

[storm crystal]

might as well do it since its the only one working so far

[rotund ravine]

We just told you the proper way

After getItem

[storm crystal]

nuh uh, didnt work

[rotund ravine]

Check

[lost matrix]

If you catch a NullpointerException like that, then im not going to give you any further advise on your code.

[rotund ravine]

You didn’t try yet

[storm crystal]

you still havent told me why I shouldnt do it

https://cdn.discordapp.com/emojis/1100436689836585010.webp?size=48&name=Shrug&quality=lossless

[hazy parrot]

if you are missing fundamentals, can you atleast try to not be rude

[storm crystal]

why not use something made to catch errors to catch errors

[rotund ravine]

Sec

[lost matrix]

Because it simply hides a fundamental problem with your code.
Its like kicking your cats excrements under the fridge and calling the problem solved.

[lost matrix]

Because try catch blocks are used to catch unexpected exceptions.
Your exception is not unexpected. Its even ensured to happen.

[rotund ravine]

A NullPointerException is an error that happens when you try to use a variable that has no value. For example, if you declare a variable like this:

String name;

and then try to do something with it, like this:

System.out.println(name.length());

you will get a NullPointerException, because name has no value assigned to it. It is like trying to measure the length of nothing.

One way to avoid NullPointerExceptions is to check if the variable is null before using it, like this:

if (name != null) {
  System.out.println(name.length());
}

This way, you will not try to use a variable that has no value.

Another way to avoid NullPointerExceptions is to make sure that you always assign a value to your variables when you declare them or soon after, like this:

String name = "Alice";
System.out.println(name.length());

This way, you will not have any variables that are null.

Some people might think that catching a NullPointerException with a try-catch block is a good way to handle this error, like this:

try {
  System.out.println(name.length());
} catch (NullPointerException e) {
  System.out.println("Oops, name is null!");
}

However, this is generally a bad practice for several reasons¹²³⁴:

• Catching a NullPointerException means you are hiding or ignoring the actual bug in your code. Instead of fixing the problem that causes the variable to be null, you are just covering it up with a catch block. This can make your code harder to debug and maintain.
• Catching a NullPointerException can make your program behave unpredictably. For example, if you catch a NullPointerException and then return a default value, you might end up with incorrect or inconsistent results. For example, if you catch a NullPointerException and return 0 for the length of a name, you might end up with wrong calculations or comparisons later on.
• Catching a NullPointerException can make your code less readable and understandable. For example, if you catch a NullPointerException and then print a message or log an error, you might confuse yourself or other developers who read your code. They might wonder why you are catching this error and what it means for the logic of your program.

Therefore, it is better to avoid causing NullPointerExceptions than to catch them. You should always initialize your variables with proper values and check for null values before using them. This will make your code more reliable, robust, and clear.

@storm crystal

Java is a popular and powerful programming language that can be used to create various applications, including spigot plugins for Minecraft servers. Spigot plugins are pieces of code that add or modify the features and behavior of the game¹. To create spigot plugins, you need to have a good understanding of the Java basics, such as syntax, variables, data types, operators, control structures, methods, classes, inheritance, interfaces, exceptions, and collections².

Learning Java basics before using it for spigot plugins is the best way to start because it will help you to:

• Write clear and efficient code that follows the Java conventions and standards³.
• Avoid common errors and bugs that can cause your plugin to malfunction or crash the server⁴.
• Use the spigot API and documentation effectively to access and manipulate the game elements⁵.
• Debug and test your plugin easily using various tools and methods⁶.
• Extend and improve your plugin with more features and functionality using advanced Java concepts⁷.

Asking basic questions without at least trying to learn is rude to the ones answering because it shows that you are not willing to put any effort or time into learning Java. It also wastes the time and energy of the people who are trying to help you. There are many resources available online that can teach you Java basics, such as tutorials, courses, books, videos, blogs, forums, etc⁸. You should use these resources first before asking for help. If you still have questions or problems after trying to learn, you should ask them in a polite and respectful way, providing as much detail and context as possible. You should also acknowledge and appreciate the answers that you receive from others.

If you continue to ask basic questions without trying to learn, you should seek help elsewhere because you will not be able to create spigot plugins successfully. You will also annoy and discourage the people who are trying to help you. You may even get banned from some communities or platforms for spamming or violating their rules⁹. Therefore, it is better for you to find another way to learn Java basics or another project to work on.

I hope this explanation helps you understand why learning Java basics before using it for spigot plugins is the best way to start. If you have any other questions or requests, please let me know. 😊

[storm crystal]

last time I asked someone on discord if I know enough java basics for plugins they told meI do after asking a few questions

https://cdn.discordapp.com/emojis/1100436689836585010.webp?size=48&name=Shrug&quality=lossless

[glad prawn]

ur not

[prisma raft]

also, when your two alternatives are

if (will error) {
  // do nothing
} else {
  // do stuff that you now know won't error
}

and

try {
  // do stuff that may error
} catch (Exception e) {
  // do nothing
}

then both of them are pretty bad, because of how "do nothing" usually isn't exactly what you would want to happen when something doesn't work as expected (because that way, when something goes wrong, it won't blow up instantly and tell you about it, but instead the error will sneak around your program), but that being said:

handling your logic through try-catch blocks isn't really how java is designed and really bad for performance, so if your program is just performing normal logic and you have the choice between doing the same thing with if else or with try catch, never do the latter

[rotund ravine]

You're not at a point where i would say you know java basics to any point that is reasonable to start asking questions here. At this point it feels like we are writing your plugin and you are just directing ideas. We are not being paid for this, and that is the reason we usually program for someone. Whoever said you knew enough are clearly either taking the piss on you or have poor judgement. You have displayed a reasonable doubt on your knowledge of even simple sequential execution, simple nesting and scopes as well as simple conventions. I say simple because, these are what you will be learning at the start of any simple programming course. There is no doubt in my mind that you either need to learn by fire and simply do things yourself, or go take a basic course before continuing ask questions, because I will at least not entertain you anymore than I already have.

[umbral ridge]

hey what's that line in jetbrains ide?

A code guideline?

[river oracle]

visual for line wrapping

your lines will wrap if you go past that point

[umbral ridge]

ohhh

okok

[umbral ridge]

I always though it was like a code length limit lol, like guidelines

I never type code that's longer than that now anyways

[river oracle]

no I don't believe java has any set standard on how long your code can be in asingle line

usually people use like 80 pretty sure

my code wraps at 144 characters though

[umbral ridge]

Oh

[echo basalt]

think I have mine at either 100 or 120

[prisma raft]

there are various standards, but they aren't exactly "global"

[echo basalt]

80 is a bit short

I just use google style with 120 wrap

[river oracle]

for reference thef irst line is 80 characters the second line is 144

[echo basalt]

imagine using an arch background lmao nerd

[river oracle]

what?

[echo basalt]

looks like arch

[river oracle]

who are you talking about

its not lmao

[prisma raft]

like for example, the google style guide says to use 100:
https://google.github.io/styleguide/javaguide.html#s4.4-column-limit

[river oracle]

its my favorite tree

[umbral ridge]

i like how you put javadoc as well,

I put javadoc everywhere

[lost matrix]

Could as well put yt videos in the background...

[river oracle]

meta, spigot tutorial in background

[lost matrix]

Thats bc they have devs working on 4:3 screens or their tablets.
Thats one of the few style choices i dont use.

[prisma raft]

just saying that there are standards, but not everyone is using the same standards

[inner mulch]

Is there an event that listens to a player using the middle click to copy a block to the hot bar in creative?

[river oracle]

I mean that could be said for anything, my initial response of there being no java standard was quite correct

there are company standard

[river oracle]

pretty sure that isn't even sent to the server

creative mode is mostly clientside

[inner mulch]

is there one for survival tho?

doesnt need to be creative

[umbral ridge]

Is this required? The warning is annoying

[lost matrix]

You should probably do a null check before

[compact haven]

it’s there because getString can return null if that key isn’t in the config

[umbral ridge]

Alright

[prisma raft]

well you've also got the Oracle style guide claiming to be the java standard that reflects the standards of the language specification, and it says you should use 80 chars, but ig I should've led with that when talking about "the" standards

but we can probably agree that you just meant that there is no standard that everyone adheres to, which is most definitely correct

Anyways, to talk about what I came here for:

I've been thinking about writing a tool to convert the schematic files that you get from worldedit to nbt files that you could load in vanilla, and what I found so far was this:
https://github.com/EngineHub/WorldEdit/blob/master/worldedit-core/src/main/java/com/sk89q/worldedit/extent/clipboard/io/MCEditSchematicReader.java
which is referenced in the minecraft wiki as an implementation of the schematic file format used by mcedit and other mods/programs.
I've read through the code a bit and figured out that it probably reads from this file:
https://github.com/EngineHub/WorldEdit/blob/master/worldedit-core/src/main/resources/com/sk89q/worldedit/world/registry/legacy.json
to convert from the legacy numeric IDs that the file format uses to get actual BlockState values that can actually be useful.

Now what I wanted to ask is whether anyone knows if this format seriously is what MCEdit uses, because

1. the format is crazy convoluted, and at least when having its core component be a method with the word "legacy" in the name you'd expect the dev to think twice and start deprecating the format, but I don't see the class being described as deprecated anywhere, and
2. as opposed to other files in the same folder, legacy.json hasn't been updated for 2 years, so it probably doesn't even have newer blocks reflected in it, which is also hard for me to believe.

So, does anyone know if I can find a newer implementation anywhere, or if I misinterpreted something and the implementation that I pointed to actually does handle the newest version just fine, or if MCEdit is just that bad?

also please tell me if I'm asking in the wrong place, like if you'd rather I annoy the actual worldedit devs about this

I only just noticed that they have their own discord server

[lost matrix]

legacy.json refers to legacy block ids in minecraft. It doesnt need any updates because mojang cant release versions in the past
So all this does is translate IDs from old schematics to ones that can be used in newer versions of minecraft.

[prisma raft]

yeah that's what I thought, the question is where I'd find a documentation of the format as it's used in modern versions

since the one that I found seems to only be mapping from the numbers it reads using legacy.json

[lost matrix]

I dont think the schematic file format changed in the last 5 years or so

https://minecraft.fandom.com/wiki/Schematic_file_format

[dry hazel]

there's also the sponge schematic format https://github.com/SpongePowered/Schematic-Specification/blob/master/versions/schematic-3.md

[prisma raft]

oh I've been misspeaking this whole time, I think I said MCEdit a few times when I've been referencing (and meaning) WorldEdit

[lost matrix]

I remember when Sponge was big hype. Was still during bukkit times 🙂

[prisma raft]

but you seem to have understood correctly despite me misspeaking

[lost matrix]

MCEdit and WorldEdit both support the .schematic format so its fine

[young knoll]

Worldedit uses sponge version 3 schematics atm

[prisma raft]

anyways, the wiki page that you linked to is what I started with, and the java class that I linked to is what the wiki gives as the first entry under "Implementations"

[lost matrix]

This is the format you want to translate into btw
https://minecraft.fandom.com/wiki/Structure_Block_file_format

[young knoll]

Well, when saving

It can load various versions

[prisma raft]

yeah I've written programs that write vanilla structures before, but thanks

[prisma raft]

but if this is the version that WorldEdit is using right now, that's very helpful

[storm crystal]

what am I doing wrong with spawning a particle

[smoky oak]

maybe ur spawning it at the wrong location

[lost matrix]

Looks alright.
Add a debug statement after this line and see if it even called.

[zinc lintel]

i have a question

will this work the way i did it?

its just so i can have it organised

[dry hazel]

yes

[echo basalt]

?conventions

[undone axle]

https://www.oracle.com/java/technologies/javase/codeconventions-namingconventions.html

[storm crystal]

how do I make short delay

[inner mulch]

hashmap (if u asking for cooldowns)

[storm crystal]

no, just a short delay like 0.1s

[inner mulch]

that pretty much a cooldown

hashmap<UUID, Long>
and for the long you use system.currenttimeinmillis or something

when the player tries to do next action

just see if previous time equals current time

[hazy parrot]

You mean delay in your code or cooldown?

[storm crystal]

former

I want to make one action, wait 0.1s and then do another action

[tall dragon]

Thread.sleep

[tall dragon]

oh i was jokin dont do that ;d

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[storm crystal]

???

[tall dragon]

what

[quaint mantle]

It gonna hang the server

[echo basalt]

sigh

do it

no balls

see what happens

[hazy parrot]

Why do you want to wait?

[storm crystal]

nevermind ill just make it half work

[hazy parrot]

You can use BukkitSchedluer#runTaskLater

[vocal cloud]

Can’t Keep Up! Is the Server Overloaded

[hazy parrot]

Just keep up smh

[prisma raft]

when someone sends a guide that explains what you do, good responses would be either to read the guide and do what it says or, if you don't understand something about the guide, not just say "???" but actually explain which part of the guide you're having issues with

[quaint mantle]

Thread.getCurrentThread().join() to get max performance /s

[warm mica]

If you do not know what this method does and what the consequences are, do not use it

[storm crystal]

the "???" part was about that

[prisma raft]

well that part is what the guide explains in the first paragraph

[inner mulch]

if i connect a sql database in the onEnable method, how do i return the connection to a class that manages the data from the database?

[ivory sleet]

or just LockSupport.park()

[storm crystal]

idk maybe im weird but giving someone a joke answer just to follow up with actual answer once they try the former out doesnt sound any apropiate in #help channel

[rotund ravine]

Just use thread.sleep no balls

[prisma raft]

they seem to have misjudged how you'd interpret their original message. It was clearly meant as a joke, though recognizing that does need basic java knowledge

but shuriken wasn't around to see other people already having pointed out that you don't have that, which probably is why they misjudged that

[storm crystal]

mhm

how can I make a code that would run every x seconds when a certain condition is met

[chrome beacon]

Use the scheduler

[thin iris]

bombastic side eye

use a scheduler

[chrome beacon]

?scheduling

[undone axle]

https://www.spigotmc.org/wiki/scheduler-programming/

[storm crystal]

is there no other option?

[hazy parrot]

Yes there is, use executor service

[chrome beacon]

Why?

[hazy parrot]

Altrough no reason for other option lol

[storm crystal]

I dont get it

[hazy parrot]

BukkitSchedluer made it easy enough

[chrome beacon]

Which part

[storm crystal]

like tf is lambda

[lost matrix]

Executors are quite similar. Even a bit more complicated. I would try to use the BukkitScheduler

You dont need a lambda for this

[storm crystal]

lambdaexpression, lambdabody, extends, , supplier

[lost matrix]

Yeah, skip all of that

[chrome beacon]

() -> this

[storm crystal]

?

[chrome beacon]

I suggest you look at some Java tutorials

[rotund ravine]

Just use the bukkitrunnable with the anonymous inner class

[rotund ravine]

Ahahah. We told him

A few hours ago

[chrome beacon]

Yeah that usually happens

[prisma raft]

lambda expression is a shorthand that lets you create anonymous classes where only one method is left to be implemented

[chrome beacon]

They always refuse to learn java for some reason

[storm crystal]

what does anonymous class mean

[prisma raft]

it's the concept that lambda expressions are based on

[rotund ravine]

Yeah

I told em we would get tired of writing his code for him

And that i would ignore him

[storm crystal]

having to watch 12hr long video and write god knows how many programs just to print that one thing is just like swallowing a porcupine

[prisma raft]

basically, when you have an interface, you don't need to create a new class implementing the interface to be able to instantiate it, you can instantiate directly and put the class implementation right after the object constructor

[rotund ravine]

I do wonder if a porcupine baby is spiky

Cause that’s about the size i can swallow

I think

[chrome beacon]

Could just pay someone 5$ to do it

[rotund ravine]

Idk how big a porcupine baby is

[lost matrix]

Step 1) Write a class which extends BukkitRunnable

public class SomeScheduledTask extends BukkitRunnable {

  @Override
  public void run() {
    System.out.println("Test");
  }

}

Step 2) Get your JavaPlugin instance and start this task:

    JavaPlugin plugin = ...;
    SomeScheduledTask task = new SomeScheduledTask();
    int initialDelay = 5;
    int repeatedDelay = 100;
    task.runTaskTimer(plugin, initialDelay, repeatedDelay);

This will call the run() method after 5 ticks (which is ~250ms) and then every 100 ticks (which is ~5s)

[rotund ravine]

https://tenor.com/view/cute-hedgehog-baby-gif-19977222

Yeah i can’t swallow that

[lost matrix]

Dont bother with all of that. You need to stick to the basics

[prisma raft]

what this is doing is that it's creating a new class that implements the interface, but because it doesn't give a name to the class but instead just instantly uses it to instantiate an object, the class that it creates ends up not having a name

[storm crystal]

you aren't deigned to write the code for me

[prisma raft]

that's why it's called "anonymous"

[storm crystal]

I didnt force you at all to help me, you did it willingly lol

[rotund ravine]

We all make poor choices

[lost matrix]

Ok... cute, ngl

[rotund ravine]

Ikr

[lost matrix]

Dont like how he strikes his wiener but the thing is cute

[prisma raft]

I think the point is that they have no problem with helping, but are warning you that that won't be the case if it turns into them writing all the code for you, or them giving a full guide on java basics

[rotund ravine]

You think that’s his wirner?

Baby getting some special service then

[lost matrix]

lol

[prisma raft]

imo it doesn't make much sense to recommend lambda expressions when you call anonymous classes too far away from the basics

[storm crystal]

if its so bothersome why hasnt there been any rule which states that you are required to know at least this and that to ask questions?

[lost matrix]

I didnt recommend lambdas 🙂

I told him to make a concrete impl of BukkitRunnable

[rotund ravine]

Why do you think

?learnjava

[undone axle]

Here are some links to get you started on learning Java:

• https://www.codecademy.com/learn/learn-java
• https://www.sololearn.com/learning/1068
• https://www.learnjavaonline.org/
• https://programmingbydoing.com/
• https://docs.oracle.com/javase/tutorial/java/index.html

The last one is the only official one, however some of those concepts assume that you already know a bit about programming.

[wind veldt]

SoloLearn the goat

[prisma raft]

oh you're right, I thought someone mentioned lambdas to them and then they asked, but they just asked on their own

[prisma raft]

it's not hard for helpers to explicitly say "conversations here are based on java basics, please inform yourself about those" and send links to places to learn java basics, which iirc happened pretty early in this conversation

I don't think people will blame you for asking questions without knowing the basics, though some seem annoyed that you claimed to know the basics despite having to ask about basically every basic java concept that was relevant so far

[storm crystal]

let me get it straight, am I or am I not in any right to ask questions here despite apparently not getting all basics

[rotund ravine]

You are allowed to be here just fine. Expect to get told to learn the basics at each question though

[wind veldt]

what was your question to begin with? all I see here is ppl telling you they wont write code for you and telling you to learn the basics

[rotund ravine]

.

[wind veldt]

thx

[storm crystal]

.

[prisma raft]

(that was already answered btw, they were just complaining about the manner in which it was answered)

[wind veldt]

oh

[rotund ravine]

Smiley was even nicer and answered in another way too

Can’t u add a few more

[storm crystal]

first I was straight up trolled and then I got answered by JanTuck about how he wont answer me ever again

[rotund ravine]

No i was talking to

Ehhh that other guy

[prisma raft]

they gave a joke answer that they thought anyone would recognize as not being serious and gave the link to the guide explaining what you want to do right afterwards

[wind veldt]

Let's end the argument here, @storm crystal man if you feel their answer is incomplete or the guide they sent is too complex, just DM me and I'll quickly explain what and why

[rotund ravine]

That’s nice of you

I’d be way too lazy

Also rip chandler bing

Is this a prelude to some bible thingV

[wind veldt]

He's bout to tell us some prophecies

shush

xD

[rotund ravine]

He got quiet

Nvm

Woah

[lost matrix]

Did they update it finally?

[prisma raft]

also I think "basic java" is pretty poorly defined. Most of the guides that the bot lists here already count just inheritance as advanced knowledge, while the people here seem to count anything as basic that is a commonly used concept or language feature. Which I'd agree with, because I'd call something basic if it's used for basically everything, but it's still hard to tell someone "learn the basics" and then link a guide that lists the thing that they just said to learn as being an "advanced topic"

[rotund ravine]

I have never used any of these guides so wouldn’t know 😬

[storm crystal]

if people are so arsed by not knowing "basic java" then they just should make list of required terms themselves

[umbral ridge]

I'm trying to detect if player moved for 1 block, is this how it's supposed to be done? any better way? less code?

[rotund ravine]

We work by a principle called Don’t reinvent the wheel

[wind veldt]

Wait guys

You know what the guy DMed me?

[rotund ravine]

Thst you suck?

Jkjk

[wind veldt]

He DMed me in polish, saying that no one asked for my opinion and I didnt bring anything into the convo

[lost matrix]

This will only be true if a player moved one block in a single tick.
He would have to be insanely fast for that

[wind veldt]

Crazy

[rotund ravine]

He did?

That’s funny

[wind veldt]

Yeah, its him crying out here not knowing basic things and needing help

[umbral ridge]

No it works I've tested it

[rotund ravine]

Guess he’s a troll then

[wind veldt]

For me, it doesnt make a difference whether he wants the help or not

[umbral ridge]

I'm not good at maths, help me out? xD

[lost matrix]

Ah its BlockX
In that case you should not use floats

[rotund ravine]

It’s a method on Location

[umbral ridge]

Yeah just noticed that lol

[rotund ravine]

Called distanceSquared

[storm crystal]

But if you want someone to know basic java and type ?learnjava doesnt it sound kind of unprofessional if you dont even know what those guides consist

[lost matrix]

It works but there is a method which performs slightly better. Want me to write it real quick?

[storm crystal]

like how can you be sure that they do cover basics

[umbral ridge]

that's about it?

[umbral ridge]

Yea sure

[rotund ravine]

Well they probably consist of some java knowledge that you are in need of so i don’t mind.

[umbral ridge]

Nice

easy peasy

[rotund ravine]

Why does it not like “to”

[umbral ridge]

squezy

what's wrong with it

[storm crystal]

well I wouldnt take it as apropiate help from someone who recommends something they didnt use

https://cdn.discordapp.com/emojis/1100436689836585010.webp?size=48&name=Shrug&quality=lossless

[wind veldt]

I already said which one is the GOAT, that would suggest I tried all of them but you probably went over my message without a thought lmao

[prisma raft]

I definitely recommend reading the oracle tutorial:
https://docs.oracle.com/javase/tutorial/java/index.html
it gives an explanation over everything that you should know, though it's pretty detailed, so I mostly recommend it if you're actually serious about learning java

[storm crystal]

I read it and what else

[umbral ridge]

event.getTo() might be null for some reason

[storm crystal]

is that enough

[umbral ridge]

Not sure why i'll have to look into it

[prisma raft]

definitely

[rotund ravine]

I guess

[prisma raft]

also most people seem to have issues with learning from text guides, though it might be a good fit since you said you're not looking forward to a 12h youtube tutorial

[storm crystal]

I read something similar on w3schools but apparently this wasnt enough basics

[rotund ravine]

Fairly certain duskgaler is just trolling at this point

[storm crystal]

even though someone did recommend me it earlier here

[rotund ravine]

Oh oh

Good thing i haven’t opened minecraft in over a year

[wind veldt]

lmao

[storm crystal]

you forgot to mention it like twice

[rotund ravine]

sry new people needed to know my amazing deduction

[prisma raft]

btw I wouldn't say it's necessary for you to internalize every part of the oracle guide, it's mainly good for giving an overview of which concepts even exist in the language, how they're related, and you can use it to look up something when you need to know more about it

[lost matrix]

  @EventHandler
  public void onMove(PlayerMoveEvent event) {
    Location from = event.getFrom();
    Location to = event.getTo();
    int fx = from.getBlockX();
    int fy = from.getBlockY();
    int fz = from.getBlockZ();

    int tx = to.getBlockX();
    int ty = to.getBlockY();
    int tz = to.getBlockZ();

    if (fx == tx && fy == ty && fz == tz) {
      return;
    }

    System.out.println("Player crossed a block corner.");
  }

And if you really want to nerd about a few clock cycles then you can do this:

    if ((fx ^ tx | fy ^ ty | fz ^ tz) == 0) {
      return;
    }

[umbral ridge]

^ huh I'll try it

thank you

[prisma raft]

a helper will quickly get exhausted when they need to explain every single concept, but if you can go there to read about it first and only ask when you have problems understanding, it'll probably be a much smoother experience for both ends

[storm crystal]

without it apparently I wont get much help here so I rather have to read it whole either way

[wind veldt]

I doubt he's trolling, and it's sad that he turned down a chinese nicknamed guy's help and is disrespectful :(

[rotund ravine]

Ur chinese?

[wind veldt]

nope, I just have chinese nickname on discord lmao

Just a tryhard in anything I do

[rotund ravine]

You learning chinese?

[umbral ridge]

What's the | operator? something to do with bit comparison?

[hazy parrot]

Bitwise OR

[lost matrix]

bitwise or

[rotund ravine]

Spread the influence of god by posting the bible plugin on chinese pages

[umbral ridge]

ahh

[wind veldt]

the only things I learned in chinese were some extremely offensive things because I have 2500 hours in a game named "Rust", but that aside

[umbral ridge]

okok

[rotund ravine]

Nice

[wind veldt]

hahahaha

[rotund ravine]

Poor you

[wind veldt]

💀

insane use

[storm crystal]

how am I supposed to know if something is java problem and if something is spigot problem

[rotund ravine]

If i mention taiwan do i get banned

[rotund ravine]

Google

[wind veldt]

on chinese servers, yes

[umbral ridge]

hey btw why is event.getTo().getBlockX() the only one that can produce a NullPointerException?

[rotund ravine]

Why, wouldn’t the “one-china” thing allow me to mention it by saying they are one of us

[wind veldt]

Experience or a guy helping ya, which you turned down lmao

good tip, will be executed immediately

[storm crystal]

Mhm, yeah

[lost matrix]

Because there are occasions where the to Location is null.
Cant quite remember when.

[rotund ravine]

台湾是我们的一部分

[storm crystal]

Thats what I was talking about but ig

[umbral ridge]

Thanks ill look into it

[lost matrix]

And all calls afterwards cant produce a NPE bc the first one would already exit the method with throwing an exception

[hazy parrot]

If you can't differate you having problem with spigot api, and having lack of programming knowledge, I just, idk

[rotund ravine]

I know everything, bow down before me peasant

[wind veldt]

🙇‍♂️

[rotund ravine]

Racistt

Banned

[umbral ridge]

Yeah i see, thanks again 🙂

[prisma raft]

that's why I recommended loosely reading through the guide first, so you know what's explained inside. Also I just read back on the earlier lambda conversation, because "like tf is lambda" definitely is something you could've looked up in a guide, but the original guide about scheduling something already introduced lambda by first explaining what it is and what it does

[rotund ravine]

Funny

[prisma raft]

as a general tip, anything that needs to be imported first with a minecraft-specific prefix or something like that is part of spigot, and anything that looks like it's part of the syntax or is part of a java library (so it's imported as something not minecraft-specific) is part of general java

[rotund ravine]

What’s an import

[tall dragon]

why is this not possible ;,/

[wind veldt]

Whats an java

[rotund ravine]

Cause java generics

[lost matrix]

Because your constraints dont allow insertion like that

[echo basalt]

oo you're making that

[rotund ravine]

Class<? extends event>

[tall dragon]

yea im about to throw my pc out the window

fking generics

[echo basalt]

yeah they easy

[rotund ravine]

As the lord praised

[storm crystal]

I hope you are having fun at least

[wind veldt]

I would certainly do a PC throwing competition with you, but I don't have a problem with spigot right now

[rotund ravine]

Famous last word

[tall dragon]

is there a way something like ive shown could be done?

or should i forget it

xd

[lost matrix]

Sure

Map<Class<? extends Event>, Consumer<? extends Event>>

[echo basalt]

https://sourceb.in/5O52CFv7pA

:)

[rotund ravine]

In the realm of software development, Java Generics are a blessing, akin to divine favor. Just as the Lord praised the heavens and the earth, so too do Java developers extol the virtues of generics.

In the beginning, there was chaos in the land of Java. Developers were constrained by the limitations of non-generic code, as they could only deal with objects of a specific type. It was a time of great toil and inefficiency.

Then, in their wisdom, the creators of Java bestowed Generics upon the codebase. And it was good. With Generics, developers could create classes, methods, and interfaces that were not bound to a single type but could work with a multitude of types. This was a revelation, much like the parting of the Red Sea.

As the Lord divided light from darkness, so did Java Generics separate type safety from ambiguity. With the power of Generics, developers could catch type-related errors at compile time, preventing the plague of runtime errors that plagued the non-generic code of old.

Just as the Lord's commandments guided the people of old, so too do the principles of type erasure and wildcards guide Java Generics. They offer flexibility, yet with great responsibility. Developers must heed these principles to ensure the sanctity of their code.

Like a divine choir, Java Generics allow for more elegant and reusable code, bringing joy and harmony to the land of Java. The ability to create generic collections, classes, and methods is a testament to their versatility.

In the annals of Java, Generics are celebrated as a gift from above. They are a testament to the power of abstraction and polymorphism, allowing developers to write code that is more generic and adaptable, much like the wisdom of the scriptures.

Indeed, in the world of programming, Java Generics are a blessing bestowed upon the faithful, enabling them to write code that is both powerful and safe. So, let us continue to sing praises to Generics, for they are as easy to use as the Lord's grace is to receive.

[prisma raft]

I don't do java very often, am I right in saying that this would be totally fine code if java just wasn't too stupid to read it?

[rotund ravine]

Probably

[tall dragon]

right but then u run in into the next problem on the other end when u have an instance of Event but it wants a capture of ? extends Event

[echo basalt]

make a hacky cast

[rotund ravine]

Well casting 💪🏻

[storm crystal]

Is there any skript guide I could watch/read?

[tall dragon]

😂

[rotund ravine]

Wouldn’t know

We don’t really help with skript here i think

[lost matrix]

Unsafe cast is fine here as long as you strongly encapsulate your map

[rotund ravine]

They do on the forums

[wind veldt]

hahaha

[storm crystal]

Spigot forum or other forums?

[rotund ravine]

Thought u were talking about twitter for a moment

Spigot forums

Idk if there are other forums

[storm crystal]

Well idk either

[tall dragon]

right yea i guess ur right

[rotund ravine]

I would suggest trying to google skript

[storm crystal]

I guess I could work with that

[wind veldt]

You could have worked with plugins in less than a few minutes if you weren't arrogant, sorry but it has to be said.

[storm crystal]

Yeah sorry for asking questions in question channel

[lost matrix]

  @SuppressWarnings("unchecked")
  public <T extends Event> void publish(T event) {
    Consumer<T> consumer = (Consumer<T>) this.eventHandlers.get(event.getClass());
    consumer.accept(event);
  }

In the end your map is just a Map<Object, Object> and you need to make sure that nothing is added
to this map, unless its done with your method. This method creates constraints that make your code safe (at least on compiletime)

[echo basalt]

null check

[lost matrix]

Yeah, sure do that as well

[tall dragon]

alright il go ahead and try that

[rotund ravine]

https://www.spigotmc.org/resources/visual-bukkit-create-plugins.76474/ try this out

[prisma raft]

as was already explained, this server doesn't really help with skript. "asking questions in question channel" clearly isn't the problem

[storm crystal]

Whats that

[rotund ravine]

Idk

Smth visual

Like how programming is taught to kids

[storm crystal]

Mhm

[lost matrix]

  @SuppressWarnings("unchecked")
  public <T extends Event> void publish(T event) {
    Optional.ofNullable(this.eventHandlers.get(event.getClass()))
        .map(consumer -> (Consumer<T>) consumer)
        .ifPresent(consumer -> consumer.accept(event));
  }

Just for you without null check 🫰

[storm crystal]

What kind of plugins can be made with this

As in to what extent

[echo basalt]

optional

[wind veldt]

That stuff is fire if someone wants to make something real quick w/ no programming knowledge

[echo basalt]

nooo

[wind veldt]

Try yourself, he probably never used it since he's a spigot god

[prisma raft]

probably exactly what's listed under "documentation"

the list isn't super long

[storm crystal]

Why does he recommend something he hasnt used

[echo basalt]

let's create a new object for checking nullability hurray

[rotund ravine]

We do that a lot

[wind veldt]

He did research for you, found something nice, probably checked what it can do beforehand as well and being a good programmer he almost certainly knows that it's good

[rotund ravine]

I just checked over the description and documentation

[storm crystal]

He literally said idk

[wind veldt]

Dude you just wanna turn down everything people say here, whats up with you man

[rotund ravine]

I mean i could have said it was visual programming instead of idk

https://m.youtube.com/watch?v=tIjdBhPMs90

[storm crystal]

Im not forcing you to help me

[wind veldt]

He could have also checked the link as well... it literally says what it is when you click on it

Overview
Visual Bukkit is a visual programming language for Bukkit plugins, allowing you to create plugins without knowing Java.

[rotund ravine]

Here’s a video

[storm crystal]

I know as much..

[wind veldt]

great, try it

[storm crystal]

I asked to what extent can you make plugins

[lost matrix]

Not much probably. Read the docs. They have a list of features.

[rotund ravine]

Would be interesting to expand on

[storm crystal]

Like database management wouldnt be possible would it

[rotund ravine]

Idk

[lost matrix]

https://github.com/OfficialDonut/VisualBukkit/wiki

[rotund ravine]

https://github.com/OfficialDonut/VisualBukkit/wiki/Databases

Seems like it would i guess

[prisma raft]

btw, most browsers have a feature that they let you search for stuff by pressing Ctrl + F

[prisma raft]

after I told you at the start that the answer to that question would be to look at what's under "Documentation" and the detail you had in mind was whether it supports databases, you could've gone through the list of 13 entries and seen that what you're asking for is literally part of the list, or you could've used Ctrl + F to see if the page has any mention of it and make the computer do it for you

you're right in that nobody is forced to keep engaging with you, but you're making that sound like a suggestion

[storm crystal]

Hey I still got answered and didnt force anyone to do it, where is the problem in it?

[wind veldt]

I'm not gonna respond to him anymore man, he just wants to get everything handed out to him..

[river oracle]

wtf visual bukkit uspports databases

[lost matrix]

Go to sleep. Its late.

[rotund ravine]

Ikr

It’s actually also pretty recently updated

Does this warn me

https://discord.gg/ugkvGpu

No it didn’t

[prisma raft]

I just gave you a thorough explanation of why from now on I won't be answering your questions anymore. That's why your last question about how there's any problems with your behaviour can be left for you to answer for yourself

[rotund ravine]

There’s also a Discord for more questions

[rotund ravine]

❤️

[storm crystal]

I guess ill switch to it then

[tall dragon]

why does this work but when its wrapped in a list its suddenly inconvertable...

e.g if the map looks like this Map<Class<? extends Event>, List<Consumer<? extends Event>>> f = null;

like do i rlly need to cast each one then

[lost matrix]

Use a raw Map and

@SuppressWarnings({"unchecked", "rawtypes"})

over your class. Im going to sleep

semi-kappa btw

[tall dragon]

[storm crystal]

Well nvm I read documentation and it didnt have what I needed

Are there any other alternatives to java than skript?

[wet breach]

o.O

[tall dragon]

u can do it in any language if you are brave enough

[wet breach]

except probably don't want to. the implementation is in java, so you are best with using what the implementation does

[storm crystal]

Like in python?

[tall dragon]

looks like that indeed been done bfore yea

but i really dont recommend it

[storm crystal]

Why?

[tall dragon]

cuz its going to be slower for one

and it will probably limit what u can do by alot

[storm crystal]

Damn

There is really no other option than java?

[rotund ravine]

Any jvm language try clojure

[tall dragon]

yea for example kotlin as well

[storm crystal]

Are they easier than what the hell java is?

[rotund ravine]

Ehh

I mean probably not

Skript is probably the easiest you can get

[storm crystal]

Do they also have shit like classes lambdas methods and such

[rotund ravine]

Probably not visible without some expansion plugin

[storm crystal]

Do you know any kotlin guides for plugins

[glad prawn]

i wonder if Kotlin is easier than Java.

[rotund ravine]

It’s not really

We have everything java has and some syntax sugar.

[clever whale]

Java isn't that hard to learn, you just need to put some time and effort in to understand it

It's probably better to have that skill than look for workarounds

[storm crystal]

Idk it just doesnt seem like im capable of using java properly

[wet breach]

it takes approximately 3 months to learn some of the basics of java, and then probably 6-7 months to really get some proficiency. But this depends how well you are able to learn on your own and teach yourself. Most languages in regards to programming are relatively the same or take longer. Java is one of the few where it doesn't really take a lot of time

[clever whale]

There's a learning curve from python to Java for sure, but it'll get easier with time

[storm crystal]

Oh hell nah thats too much

I wanted it to be a small and fast project not something that would require year of studying before I could actually do it

[wet breach]

you don't need a year of studying, rather need about 6-7 months of actually using it

over time, as you use it you will become better at it

but, sounds like you just don't want to put any effort into it which is really lazy

I don't know of any other languages programming wise that doesn't require some sort of effort to learn it

so seems you are out of luck on the not learning portion

[storm crystal]

But what else am I supposed to use java for if not plugins

[wet breach]

there is all kinds of uses for java o.O

[worldly ingot]

You could make the next Minecraft!

[wet breach]

buildtools for example is made with java

just fyi

[worldly ingot]

It's used a lot in web backends as well

[storm crystal]

I dont do web

I dont know html

Sounds excessive to learn web dev to learn java

[worldly ingot]

It's for the backend, so no HTML

HTML, CSS, etc. are all front end

[kind hatch]

SASS is king. 💪

[rotund ravine]

I am wondering if i should eat some hot cheetos when my ass already burns when going to shit

[wet breach]

You could stop making excusese in why you don't want to learn something or why you can't. It is clear you simply just want everything to be easy and handed to you XD

[wet breach]

well more wouldn't more in this scenario so I say sure

[rotund ravine]

I guess that’s true they’re through in a few hours anyway

Pain is for the week thx

[wet breach]

over time your body gets used to it 😛

so eventually its not an issue XD

[storm crystal]

Mhm

Well I didnt make programming so weird and have lack of sense

I cant do anything about it

[wet breach]

idk what makes you think its weird or it lacks sense

but this could just be due to the fact you actually don't understand how computers work though or programs in general

[dire maple]

Is it possible to convert BaseComponent[] into a BaseComponent for the ProxyPingEvent? I want a gradient with a utility class that I have but if I use motdComponent[0] it just returns the first letter.. which makes sense seeing as each Component is a different RGB value.

[kind hatch]

Pass it through ComponentBuilder

[storm crystal]

Idk I am in IT uni

[dire maple]

Tried, returns BaseComponent[]

[storm crystal]

I thought I at least know something

[rotund ravine]

Programming is all about logic mostly

[river oracle]

its possible but its annoying though I don't see why you'd need to do that spigot should support the arrays

[rotund ravine]

?jd-s

[undone axle]

https://hub.spigotmc.org/javadocs/spigot

[dire maple]

Sorry - using BungeeCord

If I was doing Spigot it would be easy as using a String

[river oracle]

there is new API just introduced for this

[dire maple]

Is there?

👉 Point me there!

[river oracle]

are you coding for the latest version of bungeecord

[storm crystal]

I had logic at math analysis classes

[river oracle]

use ComponentBuilder#build

[dire maple]

Wee!

[storm crystal]

Awful shit with a ton of operators and 1s and 0s

[river oracle]

its a new method you may have to redownload the dependency

[dire maple]

It returns a BaseComponent[]? Am I not using the latest

Ahhh

[river oracle]

this can be done by pressing the refresh button

[storm crystal]

Dont think ill pass this class

[dire maple]

Let me update then, hold on

[river oracle]

build vs create

build returns the single

[dire maple]

OH

[river oracle]

create returns the array

[dire maple]

Still 1.19-R0.1?

[worldly ingot]

build() is the new and more recommended way to do it. Was added in 1.20.1

[dire maple]

Oh

[worldly ingot]

If you're on 1.19, I don't think there really is a good way to do it

[dire maple]

The Spigot maven for Bungeecord is outdated then, is the new version tag 1.20.1-R0.1-SNAPSHOT?

[river oracle]

BungeeCord should always just be latest

there's no reason to be using an older version

[worldly ingot]

It should be 1.20-R0.2-SNAPSHOT I think?

[dire maple]

I ripped it from the website

[worldly ingot]

I can't remember. It's on GitHub

[dire maple]

Will try

I should check GitHub more often 😳

[worldly ingot]

Yeah that's the correct version string

[dire maple]

Updating right now!

[worldly ingot]

From there you can use build()

[dire maple]

Yes, I'll try that now! Thanks guys

Yep! It worked - thanks so much ❤️

[umbral ridge]

What's better performance wise? Any better way to do this?

[quaint mantle]

how would i make colored args in commands liek this:

[ivory sleet]

can u even call remove()?

[umbral ridge]

Yeah

[worldly ingot]

It returns a copy iirc, it's mutable

[umbral ridge]

oo

didnt even notice

[worldly ingot]

The latter is more performant because iirc, internally it's an ArrayList, so the remove() call will have to iterate to remove

So you're effectively iterating twice, worst case

Also, != here instead of !.equals() is fine

[umbral ridge]

So the 2nd picture is better?

[worldly ingot]

Yes

[umbral ridge]

I though you have to use equals when you are comparing objects

[worldly ingot]

Not always. In this case you're comparing Player instances which will match referentially

[umbral ridge]

Ohh okay

[worldly ingot]

I'm assuming the player you're comparing against is local

And not saved in some field or something

[umbral ridge]

It's a temp variable defined within the same function, PlayerMoveEvent. I had to define it because I'm using it multiple times.

[worldly ingot]

If I'm being honest, equals() is probably safer, but you can use != specifically in this case :P

[umbral ridge]

Ok xD let's use both

[worldly ingot]

Just one is fine. You can keep the equals lol

[umbral ridge]

Also, can you create mutiple events? Eg. multiple PlayerMoveEvent and use each one differently? Eg. one for checking the AFK movement and stuff, the other one for something else

[rotund ravine]

Yes

[umbral ridge]

I don't want to throw everything I have to a single class

Ok awesome

[remote swallow]

Brigadier

[quaint mantle]

?

[remote swallow]

Thats how you get colored args

[quaint mantle]

is it an addon

[rotund ravine]

?brigadier

Nah

It’s just smth you need to interact with

[river oracle]

Can't even use brig properly with spigot AFAIK

[rotund ravine]

I am sure you can find some guide somewhere

[river oracle]

If you can that'd be news to me

Maybe I'll wrap brig for my next pr

Seems ambitious enough to me

[remote swallow]

Good fucking luck theres been like 4 pr attempts and none got far

[river oracle]

I'll maybe look at them then

Learning from previous mistakes goes a long ways

Also it's important to once you figure out it's not working to keep at it and find a good solution

[remote swallow]

Lies

Its better to have a mental breakdown and try the exact same way tomorrow

[thin iris]

@worldly ingot are u the right or left person

[rotund ravine]

He’s everything

[carmine mica]

no

its an unmodifiable view of the online players

its also one of the only non-copy collections. As in if you have a reference to the collection returned there, it automatically changes when players join/leave

[echo basalt]

I was thinking of a proxy map where the removal op just does nothing

or does something useless

[north canyon]

Is there any way to detect when another plugin runs Bukkit.reloadData()? It's clearing the custom recipes I've added with Bukkit.addRecipe()

[spare hazel]

Add recipes by checking inside the crafting table and looking for recipes

[north canyon]

Paper has ServerResourcesReloadedEvent which seems to do the trick, but I'd like my plugin to work on Spigot too

So when someone goes to craft, check to see if my recipes exist, and if not, add them again?

[spare hazel]

No

If the recipe entered is right then set the reseult to the recipe's result

You might need to mess around with nbt checks to get it right

[north canyon]

Oh, implement recipes manually?

[spare hazel]

Yeah

[north canyon]

I guess I could do that. But then why does Bukkit.addRecipe() exist if there's no way to safely use it?

[rotund ravine]

I mean

Just yell at authors reloading the data

Make a suggestion though

[spare hazel]

For the fun of it

Btw you can also use datapacks for simple recipes

[north canyon]

My recipes use custom nbt data (player heads) so sadly that isn't an option

[quaint mantle]

oh my god now it's doing a completely different rotation pattern, what

[gray saddle]

how do i get the hex color of a string?

[rotund ravine]

A string can have many hex colors

[torn shuttle]

give me a break

[rotund ravine]

I mean you could strip colors from the text and just get the difference from the colored and the non colored

[gray saddle]

ChatColor#getLastColors only returns non hex colors

[rotund ravine]

Yes

[rotund ravine]

.

[gray saddle]

hm ok

[rotund ravine]

StringUtils.difference maybe

[wet breach]

you must be inputing a value that is obtained from somewhere that is able to change

[torn shuttle]

part of it seems to be that this is somehow sensitive to my viewing direction which it should not be

so I need to fix that

[rotund ravine]

So.

String mySuperColoredString  = smth

String stripped = ChatColor.stripColor(mySuperColoredString)

String myColors = StringUtils.difference(mySuperColoredString, stripped)

Idk if that even works

I am not sure how components work jere

[kind hatch]

@river oracle You around?

[rotund ravine]

But might also be able to put it into a component and get the color from there

[torn shuttle]

now this is interesting

I thought the interpolation of teleports was only visual

does it actually get acknowledged by the server?

I think I'm starting to see why this is acting weird, I need to take a breather before I really get into it

Illusion Search Index - Event Lambdas

During the development of a project, you may come to a situation where your project's structure requires the registration of an event listener in runtime.
Below is a simple utility method that may end up coming handy.

public interface EventBus {

  /**
   * Registers an event handler for the specified event class
   * @param eventClass The event class
   * @param handler The event handler
   * @param <T> The event type
   */
  <T extends Event> void subscribe(Class<T> eventClass, Consumer<T> handler);

  /**
   * Unregisters all associated handlers
   */
  void dispose(); 

}

And a simple implementation

public class SimpleEventBus implements EventBus, Listener {

  private final JavaPlugin plugin;

  public SimpleEventBus(JavaPlugin plugin) {
    this.plugin = plugin; // Dependency inject the plugin variable
  }

  @Override
  public <T extends Event> void subscribe(Class<T> eventClass, Consumer<T> handler) {
    // Event Class, Listener, Event Priority, EventExecutor, Plugin, Ignore Cancelled
    Bukkit.getPluginManager().registerEvent(eventClass, this, EventPriority.NORMAL, (listener, event) -> {
      if(eventClass.isInstance(event)) {
        handler.accept(eventClass.cast(event));
      }
    }, plugin, true);
  }  

  @Override
  public void dispose() {
    HandlerList.unregisterAll(this);
  }
}

Sample usage:

EventBus bus = new SimpleEventBus(plugin);

bus.subscribe(PlayerJoinEvent.class, (event) -> {
  Player player = event.getPlayer();
  ...
});

Avoid using this when regular listener usage is possible. This is handy for niche situations (Minigame development)

                        int level = EnchantAPI.getEnchantAPI().getEnchantLevel(itemStack, this);
                        player.addPotionEffect(new PotionEffect(PotionEffectType.SPEED, 20*5, level-1));
                    });
                }

if you want to see cursed just take a peek at how the workflow is to go from bbmodel files to functioning in-game models

I think I'll print some 3d models to take a breather here

[rotund ravine]

Hmm?

[wet breach]

what do you mean?

[rotund ravine]

Ohh magma

[torn shuttle]

like does the server interpolate the locations itself

when you tell something to teleport

[wet breach]

I haven't really looked recently in the code for teleporting, but in the past teleporting was just glorified super fast walking and you could only see this happen if you slowed the tick speed down and watched someone teleport across your view path lol

idk if this is still true or not

[torn shuttle]

yeah so that is still true, that's what I'm calling interpolation

the thing is I thought that was mostly client-side and that server-side it was actually instant

but I saw something earlier that made me think the server actually is keeping track of these interpolated positions as well and that the client does not desync from the server when it shows the intermediate points

[wet breach]

ah, yeah its not instant on server side but it usually does a pretty good job in making it appear that way

that is why you usually have to wait a tick or so after teleporting a player to do more things with the player

[torn shuttle]

fun fact

nms has a method called setPos for entities

and that is the exact same as teleports

don't ask me how I wasted my time finding that out

[wet breach]

lol

[torn shuttle]

Is there any way to check if a mob is able to walk through a specific block material (for example grass) by only knowing the material?

[eternal oxide]

.isSolid()

[full holly]

perfect, ty

[eternal oxide]

or better, isPassable()

[full holly]

working, ty

[tiny sleet]

whats the best language to start with java or kotlin

[eternal oxide]

java

[tiny sleet]

ok

[ivory sleet]

Kotlin should be just as good to start with, but java is in a sense more traditional and doesn’t have a ton of small qol (negligible) features that may throw you off the initial learning

[valid burrow]

java. simply for the fact that its more common. you will rarely find resources made in/for kotlin

(if you are trying to make plugins)

[ivory sleet]

I mean there are plenty resources

And they are usually coded much better since static abuse isn’t a thing in kotlin for instance

[valid burrow]

in comparison to java there are rather little

at least in my experience

[ivory sleet]

In terms of quantity yes, but in terms of quality its pretty fine

Its not at all too hard to find resources

And if you find something in java its not a bad practice to convert it to kotlin

[valid burrow]

yh but at certain lvls its already hard to find specific resources for java so i can only imagine the struggle for kotlin

[ivory sleet]

assuming you’te trying to learn a language

[ivory sleet]

What lvls are we talking about now?

[valid burrow]

well not level

but

just specific things

[ivory sleet]

Such as?

I can almost guarantee you, that if you are developing stuff that don’t have any documentation or resources covered for you, then that’s not a newbie friendly project you have there

[valid burrow]

never said they are newbie friendly

but

[ivory sleet]

Well look, here is a guy who is just starting with kotlin or java, shouldn’t they at least be doing something newbie friendly?

[valid burrow]

in spigot and java the line you need to cross to get into rather ‘complicated‘ topics isnt that far

[ivory sleet]

Not true at all

[valid burrow]

well that may be your experience but i can say it was the other way around for me

[ivory sleet]

Spigot is almost entirely single threaded, the api is java 8 ish, what line are you referring to?

[ivory sleet]

Yeah that’s fair

I just do think if you choose the right project to learn a language with, kotlin will be just (almost) as straightforward as java will be

[valid burrow]

well i wasnt a complete newbi when i started with java so that probably also influenced it a bit

[ivory sleet]

Hmm, yeah, i mean its one thing if there is a topic no one has really sort of dived into before you have

so that’s a fair point

[lost matrix]

https://tenor.com/view/cute-hedgehog-baby-gif-19977222

I really dont like the idea of starting with kotlin because you have never experienced the importance of null safety.
This makes one of the best selling points of kotlin hard to understand and appreciate for beginners.
Like, what are they gonna do with all those signs, named after dead musicians?:

[onyx fjord]

Kotlin is fake

[lost matrix]

I kinda like it. But i also think that it needs more constraints. Some features just break code standards by simply existing.

[valid burrow]

valid point

[onyx fjord]

Might as well be called android lang

[eternal oxide]

I dislike optional

[ivory sleet]

yeah Optional is goofy

[glad prawn]

why 😭

[ivory sleet]

because its engineered incorrectly

for one there is no subtype of optional that defines presence/absence

let me explain

[slender elbow]

jdk's Optional is pretty mediocre

[glad prawn]

Optional is primarily intended for use as a method return type where there is a clear need to represent ‘no result,’ and where using null is likely to cause errors. A variable whose type is Optional should never itself be null; it should always point to an Optional instance. i just hope no one uses it the wrong way

[loud herald]

Hello, does anyone know how i can fix that when a armorstand is riding a player, i can't teleport the player through dims? Nether portals don't work and /tp also not. But if i remove the stand, it works. No tp event is triggered when the stand is riding the player.

[ivory sleet]

//assume this method is very huge
void doStuff(Optional<User> userOption) {
  //here is a lot of code (imagine it)

  //later in the function
  if (userOption.isEmpty()) {
    UserSerializer.serialize(userOption.get())
  }
}

//now lets say we wanna make that method smaller

void doStuff(Optional<User> userOption) {
  //here is a lot of code (imagine it)

  //later in the function
  if (userOption.isEmpty()) {
    serializeUser(userOption);
  }
}

//one of our extracted functions
void serializeUser(Optional<User> userOption) {
UserSerializer.serialize(userOption.get())
}

this might not be the best example as serializeUser() could simply take a User instead, but that may not always be possible. So the issue here is that we lose any awareness of the presence of the value in the optional, which happens often when we jump to a new scope of code.

[wet breach]

you need to dismount riders before teleporting

and then remount after teleporting

this is also true if it was the other way around

[loud herald]

How can i detect if the player is being ridden?

[wet breach]

check for riders?

or passengers

[loud herald]

I mean like no teleport event is called so i can't detect if the player tries to get tped

[ivory sleet]

@glad prawn

[wet breach]

well, I assume they use a command right?

which would be the first event that gets fired

[loud herald]

Portals don't work too

[wet breach]

there is a portal event if I recall

[ivory sleet]

ik you never said it

[loud herald]

Yes but /tp playerThatHasAPassenger @s also doesn't work

[wet breach]

that is a command

commands have their own events

[loud herald]

Yes obv i could make a custom tp command but that is kinda hacky and probably not the way to go

[wet breach]

you don't need a custom tp command

commands in the server throw their own command event

[loud herald]

Yes i could listen...

[ivory sleet]

yes but if you go up and read the message history again you may find out that the message wasn't to you

[loud herald]

But this is hacky

[wet breach]

you are the one that wants armorstands riding players

so its already hacky and weird

[loud herald]

Any other way to attach an armor stand to a player then??

[ivory sleet]

@umbral ridge why?

[wet breach]

could make it float I suppose

[umbral ridge]

Forgot to tag one person to return the cat

nvm

[loud herald]

Wdym

[ivory sleet]

mye, well you can send gifs in general, a bit more appropriate there 😅

[rotund ravine]

Functional programming stonks

[ivory sleet]

mye that'd be nice, with some jit optimizations and what not

[wet breach]

attaching an entity to another just makes it convenient in terms of you don't have to implement anything to keep it near the player, however you could always simulate the entity being attached to another manually by making use of vectors, velocities etc.

[ivory sleet]

tho java alr said that they dont plan on improving nullability

[loud herald]

Hmhmh

[rotund ravine]

Just use kotlin 🤪

[ivory sleet]

true!!

[wet breach]

does it really need to be improved o.O

[ivory sleet]

well that's a subjective question

[wet breach]

well yes and no, depends I suppose

[ivory sleet]

but iirc it got mentioned that improved nullpointerexceptions is one of the tools they think should be adequate

[wet breach]

but most people argue from the subjective side though

so I suppose that is true

[ivory sleet]

but like, bringing a binary typed union into the jdk is prob not gonna happen anytime soon

yea frost

got the @NonNullByDefault or w/e its called

and then we have the java nullness project thingy

[lost matrix]

if(param == null) {
  System.exit();
}

[ivory sleet]

right decision 👍

[eternal night]

just wait for valhalla's non nullable types

[pine forge]

Vindicator vindicator = (Vindicator) event.getPlayer().getWorld().spawnEntity(event.getPlayer().getLocation(), EntityType.VINDICATOR);
AttributeInstance attribute = vindicator.getAttribute(Attribute.GENERIC_MAX_HEALTH);
attribute.addModifier(new AttributeModifier(UUID.randomUUID(), "Viking Horn", 2, AttributeModifier.Operation.MULTIPLY_SCALAR_1));
vindicator.getPersistentDataContainer().set(DominionSMP.DOMINION_ENTITY_KEY, PersistentDataType.STRING, "VIKING_" + event.getPlayer().getUniqueId());

Im trying to spawn this vindicator with double the health but for some reason, it vanishes after a fraction of a second, no error in the console

[smoky anchor]

Switch difficulty from peaceful ?

[pine forge]

oops

-_-

cant remember setting that to peaceful but it is

[smoky anchor]

-_-

[pine forge]

well thanks

it works now

[smoky anchor]

you're welcome
ty for giving me a laugh :D

[pine forge]

np haha

the health seems to still be at 24 though, do i have to setHealth(getHealth() * 2) after adding the modifier?

[ivory sleet]

https://hub.spigotmc.org/javadocs/spigot/org/bukkit/entity/Player.html#sendHealthUpdate()

[pine forge]

only works on the player

[ivory sleet]

oh wait i didnt read at all

well I think it should work fine to change max health the way you do it, and then set the health?

i mean I would probably do it in the spawn callback instead, but doubt that'd make a difference

[pine forge]

        AttributeInstance attribute = vindicator.getAttribute(Attribute.GENERIC_MAX_HEALTH);
        attribute.addModifier(new AttributeModifier(UUID.randomUUID(), "Viking Horn", 1, AttributeModifier.Operation.MULTIPLY_SCALAR_1));
        vindicator.setHealth(vindicator.getAttribute(Attribute.GENERIC_MAX_HEALTH).getValue());

yeah this works, i did have to change the modifier value to 1

even though its multiply

[smoky oak]

i believe both addition and multiplication for attributemodifier are called scalar

[pine forge]

not sure what that scalar thing means

[ivory sleet]

nms wise u have one add, and then one of them is multiplication with base, and the other one is multiply total

[pine forge]

why doess multiply with 1 double the value then?

[ivory sleet]

prob because this baseValue *= 1.0 + modifier

is the code pretty much

so it becomes 1.0 + 1 = 2

then 2*baseValue

:)

[pine forge]

okay thats confusing

but alr

not my code

[ivory sleet]

yeah well javadocs says:
Multiply amount by this value, after adding 1 to it.

[pine forge]

okay
