inb4 legacy version

[serene sigil]

how do i turn this method to the PlayerProfile thing?

public ItemStack getCustomTextureHead(String value) {
        ItemStack head = new ItemStack(Material.SKULL_ITEM, 1, (short)3);
        SkullMeta meta = (SkullMeta) head.getItemMeta();
        GameProfile profile = new GameProfile(UUID.randomUUID(), "");
        profile.getProperties().put("textures", new Property("textures", value));
        Field profileField = null;
        try {
            profileField = meta.getClass().getDeclaredField("profile");
            profileField.setAccessible(true);
            profileField.set(meta, profile);
        } catch (IllegalArgumentException | IllegalAccessException | NoSuchFieldException | SecurityException e) {
            e.printStackTrace();
        }
        head.setItemMeta(meta);
        return head;
    }```

[rotund ravine]

Don’t do that

Don’t be a dummy

?skull

Hmmm

[serene sigil]

lol

yea i want to get a custom skull form base64

[rotund ravine]

#help-development message

[serene sigil]

ok

[rotund ravine]

You will get a shitton of warnings in console if u do that

[serene sigil]

oh

i see

[rotund ravine]

`[15:23:39 WARN]: Found inconsistent skull meta, this should normally not happen and is not a Bukkit / Sp igot issue, but one from a plugin you are using. Bukkit will attempt to fix it this time for you, but may not be able to do this every time.

If you see this message after typing a command from a plugin, please report this to the plugin developer they should use the api instead of relying on refl ection (and doing it the wrong way).`

[young knoll]

Oh hey that's the new message

[serene sigil]

and what is URL skinUrl = ...;?

[eternal oxide]

new URL(...

[serene sigil]

i know what what is the url?

namemc url?

[rotund ravine]

Yeah i stole it from someone else

[eternal oxide]

the mincraft skin url

[serene sigil]

how do i get that?

[eternal oxide]

one sec

?paste for me

[undone axle]

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

[eternal oxide]

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

use as you like

[young knoll]

Ew base64

So much longer than just the url

[eternal oxide]

it is, but it's just an example

there is a method there to pull the url

private String getURLFromBase64(String base64) {

[storm crystal]

how did the other way of spawning entities with Consumer Interface look like?

[serene sigil]

so i need to use the public ItemStack getHeadByProfile(UUID id, String name, String base64Texture) method?

[rotund ravine]

Yep

[serene sigil]

so what is UUID id again?

[eternal oxide]

any random id unless you are using an actual player

[rotund ravine]

@storm crystal link me the method in javadoc and i’ll tell u

[storm crystal]

https://cdn.discordapp.com/emojis/1100416057426059315.webp?size=48&name=PeepoDented&quality=lossless

[serene sigil]

wdym exactly

[storm crystal]

I think I asked the question wrong

Someone mentioned there that there is another way of spawning a custom entity

as in with custom name, armor etc.

instead of spawning it and then editing it

like the other way around

[eternal oxide]

UUID.random

[serene sigil]

ohh isee now

[eternal oxide]

or something close

[serene sigil]

and what is the String name argument?

[eternal oxide]

the name that will show on the skull

[serene sigil]

ohh

okay

and the last is the base 64 right?

[eternal oxide]

yes

[serene sigil]

how do i get that from a namemc profile?

[rotund ravine]

Cry

[eternal oxide]

lol

[serene sigil]

lol

[eternal oxide]

easiest way for you to learn, run that texture through the private method in that code and sysout the result

[serene sigil]

nvm i got it

it works

ty guys

[rotund ravine]

Ur welcome

That’ll be 25$ for my time

Elgar took longer and answered more questions, so he’ll take 85$

[serene sigil]

[wary harness]

Hey so I builded system which tracks blocks which are placed by player for older version under 1.16 because they don't have PDC
so for each chunk I got file which stores locations of placed block but only specific ones like Ores
I track them so player can place it again and mine it to get rewards and abuse natural generate block rewars system

I am currently saving on chunk unloadevent

and load chung load event

is that ok

[rotund ravine]

Sure

[wary harness]

or shuld I save data on shutdown

and load on chunk load

or what I said up is good enought for preformance

[ornate patio]

How can I modify the behavior of a dispenser firing a specific item

[knotty aspen]

BlockDispenseEvent?

If you want to shoot a different item, cancel it and shoot your own using the BlockProjectileSource from the dispenser

[proud badge]

Why does the onBlockBreak event sometimes trigger multiple times for the same block?

[rotund ravine]

?

[proud badge]

broke a block once and the event triggered 2-7 times

[wary harness]

some other plugin maybe calling that event

[rotund ravine]

Seems sketchy

[wary harness]

like remove other stuff you got and then test

[proud badge]

there arent any other plugins on my server

this is the stacktrace

if thats what you mean

[rotund ravine]

That’s unrelated

[quaint mantle]

can someone help me, I made a plugin on IntelliJ Idea and build it into a .jar file and it worked, but then out of no where it start failing and crashing the server, I didn't even do any change to the code. I even tried to creating a new project and transffering the code to the new project but it still crashes the server.

[young knoll]

[river oracle]

@ivory sleet did u die :(

[frail crystal]

how do i test to see if an itemstack is a certain item?

[river oracle]

ItemStack#getType??? or maybe ItemStack#isSimilar

depends on what you mean by certain item

[frail crystal]

same item but not nbt or anything

like to see if its a minecraft:stick

[rotund ravine]

type

[river oracle]

ItemStack#getType

[frail crystal]

is isSimilar for NBT and stuff?

[rotund ravine]

Yes

[river oracle]

isSimilar compares the data of the item

getType just returns the ItemType

[rotund ravine]

Material

[frail crystal]

does it compare the itemtype also or jsut the data

[river oracle]

srry I've been spending too much time with registry Pr :L

[river oracle]

both

[rotund ravine]

It compares anything but amount

Can anyone help please> https://paste.md-5.net/eleqizefor.cs

I made a plugin and it keeps crashing the server even tho it was working just fine a few hours ago, I didn't even made any changes into it.

[rotund ravine]

Exclude dependencies that are signed

[quaint mantle]

dependencies?

which ones?

[rotund ravine]

How would i know

[quaint mantle]

Then what do you mean by excluding dependencies that are signed? I don't see anything about it in the crash report. I'm just confused

[hazy parrot]

what deps are u using

show your pom

[frail crystal]

where can i find my plugin after building?

[hazy parrot]

you have to exclude their META-INF

[hazy parrot]

you would see it in your build logs

[quaint mantle]

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

that is my pom, how do I exclude the META-INF?

[rotund ravine]

Put essentials as provided

[quaint mantle]

sorry you mean in repository?

[rotund ravine]

In the pom

[clever lantern]

how can i disable beacon effects for all players?

[quaint mantle]

Oh, I just deleted the whole META-INF file and it works now.

[inner mulch]

hey, has anyone an idea on how to change a players nametag (above the head) to a color gradient? I've seen other servers do this, but i dont know how they do it :(

[rotund ravine]

M8

Set essentials to scope provided haha

[river oracle]

shading essentials ftw

[quaint mantle]

Sorry but I'm new in all this, I have no idea what you mean by that. XD

[rotund ravine]

You see how all your other dependencies

Has a line that says provided?

In the pom

Essentials wants that one too

So be a good daddy

[quaint mantle]

oh xd

[zealous osprey]

How do you call those integration things for websites?
Like the youtube player that can be added to a website.

[young knoll]

embed?

[zealous osprey]

Not sure; I'm looking for something like that for Blockbench. Cause I want a user to be able to upload a file and then display it.

[young knoll]

I don't think that exists

You'd have to make one

[hazy parrot]

iframe ?

[storm crystal]

how is mysql implementation in java called?

[hazy parrot]

you mean driver ?

[storm crystal]

the thingy that lets you do mysql stuff inside java right away

I want to find its documentation

https://cdn.discordapp.com/emojis/1100416057426059315.webp?size=48&name=PeepoDented&quality=lossless

[rotund ravine]

Google it

[storm crystal]

yeah the thing is that I dont know name and describing it didnt really work

[hazy parrot]

hibernate and jpa ?

[knotty aspen]

your description here also isn't working lol

the driver? the part of Java itself that deals with SQL, like PreparedStatement and so on?

[zealous osprey]

Could you please elaborate or point me into the right direction? That would be amazing.

[storm crystal]

https://tenor.com/view/ltg-low-tier-god-yskysn-ltg-thunder-thunder-gif-23523876

[quaint mantle]

Do you know how I can exclude the files ending with (.DSA, .RSA, .SF) in the META-INF? I figured that it was those file what was crashing the server, but everytime that I updated the plugin those files com back again.

[hazy parrot]

i mean, iframe is literally html element, let you embedd one page into other

idk if that is thing u want

[zealous osprey]

maybe, thanks

[hazy parrot]

np

[young knoll]

Wait is blockbench availible on the web?

[hazy parrot]

seems like good question for google

[rotund ravine]

Show pom

[zealous osprey]

ye

https://web.blockbench.net/

[young knoll]

Ah okay

That makes things much easier

[zealous osprey]

yeah

[rotund ravine]

Show pom @quaint mantle

[quaint mantle]

I cant right now, I'm going to work. But its the same one from the last time just that this time I includee the provided that you told me

[rotund ravine]

Then it shouldn’t include anything that is signed

[quaint mantle]

I cleaned the project and rebuild it with the provided added. But when I go into the META-INF the files are still there.

[rotund ravine]

I would need to see the pom again i guess

Also how are you building it

[quaint mantle]

I tried cleaning it first and the rebuild it, it didnt work. Then I just tried to rebuild it and it didnt work, then building it like normal and it didnt work.

[rotund ravine]

Would need to know the tasks you ran as well as pom when ur back

[quaint mantle]

I may have the pom, I remember that I made a repository

[quaint mantle]

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

That is my current pom

[rotund ravine]

Ye shouldn’t be shading anything anymore

Would love to see the insides of the jar file when u got time

[quaint mantle]

I'll probably be looking if there is any way to exclude the files from appearing inside the meta inf.

[storm crystal]

JDBC I found it

xd

[quaint mantle]

I've looked online and this appear. Would this work? : <configuration>
<filters>
<filter>
<artifact>:</artifact>
<excludes>

[queen niche]

What is the right way to spawn a armor stand display entity?

[young knoll]

Which one

[storm crystal]

how would I want to cache this kind of data where player has different datatypes under each statistic?

[young knoll]

an armor stand or a display entity?

[queen niche]

Display Entity

[young knoll]

Item, Block, or Text?

[queen niche]

an armor stand

I guess its the entity.display

[young knoll]

Okay armor stands and display entities are completely different things

Which one do you want

[queen niche]

nvm I guess im wrong then. I thought you could spawn an armor stand display entity

[young knoll]

no

Sadly there is no EntityDisplay, only item block and text

[queen niche]

I see. Thanks!

[young knoll]

Although it would be nice, hey @Mojang hit me up and i'll code it for you

[storm crystal]

HashMap<UUID, ArrayList<HashMap<DataType, DataType2>>> ?

im kinda confused on how to handle the fact that there are integers, strings etc. in values

like key : value where key would be like deaths etc.

[young knoll]

HashMap<UUID, MyDataObject>

[storm crystal]

what is MyDataObject

[young knoll]

Where MyDataObject has fields + getters for all the different values

[storm crystal]

isnt there really a table to store different data types

[young knoll]

I mean sure

[storm crystal]

like in python I could just do x = [1, "d"]

[young knoll]

But that is messy

[rotund ravine]

?pojo

[young knoll]

Make a class so you have concrete types

[storm crystal]

what is this class supposed to do

[young knoll]

Hold values

[storm crystal]

like okay I have fields that are declared somewhere

but whats a getter

[young knoll]

A method to get the value from a field

[storm crystal]

isnt field just declared

and like standing

[tranquil harness]

Does anyone know if of a plugin that forces users to use optifine?

I saw one of the newer optifine versions made this easy, but I was wondering if this exists for 1.20
https://github.com/sp614x/optifine/issues/1631

[young knoll]

public class MyDataObject {

    private String nickname;
    private int level;

    public MyDataObject(String nickname, int level) {
        this.nickname = nickname;
        this.level = level;
    }

    public String getNickname() {
        return this.nickname;
    }

    public void setNickname(String nickname) {
        this.nickname = nickname;
    }

    public int getLevel() {
        return this.level;
    }

    public void setLevel(int level) {
        this.level = level;
    }
}

Have an example

[storm crystal]

okay but I am supposed to make separate class for each column?

like deaths level rank etc.?

[young knoll]

No, just a seperate field

[storm crystal]

and how do I put it into map

[young knoll]

map.put(key, value)

[storm crystal]

no how do I put MyDataObject

Map<UUID, new MyDataObject()>?

[glad prawn]

Map<UUID, MyDataObject>

[storm crystal]

so I make it static?

[young knoll]

Map<UUID, MyDataObject> map = ...

MyDataObject value = new MyDataObject(...);
map.put(someUUID, value);

[storm crystal]

why do I make new instance for every single value

isnt that too much

cant I make like 1 instance per player

or just 1 instance

[heavy mural]

Hey,
The entity I've spawned stops rendering at 5 chunks distance, even though my view distance is 6.

This caused the player to not see the entity when they are too far away of it I'm the y-axis. Is there anyway I could fix this?

I've tried:
Setting high view distance of the entity display. (Spigot)
Setting higher simulation distance (server.properties)
Setting high shouldrenderatsqrtdistance (net.minecraft)
Setting high entity-broadcast-range-percentage (server.properties)
Setting high entity-tracking-range (Spigot.yml)

Am I missing a Setting that could help me render an entity on a higher y-axis distance between the player and the entity?

[young knoll]

You do make one instance per player..

[storm crystal]

but that just gets one value and puts that value to map

[young knoll]

what

[storm crystal]

you get value form MyDataObject and you put it to map for that UUID

but you gotta do it as many times as there are columns

[young knoll]

You create a new MyDataObject with the data of all the columns

And put that in the map for the uuid

[storm crystal]

okay but how do I make it more scalable to return as many values as I want

like so that I dont have to hardcode 3 getters

for instance

[hazy parrot]

"hardcode getters"

i hope you wouldn't add 5 new columns every day to your database

[storm crystal]

what?

Id have to make separate class for each database that Id have to make

[hazy parrot]

why is it problem to add 3 getters

[storm crystal]

its not scalable

[hazy parrot]

you define your model once, there is nothing to scale...

[storm crystal]

well Id have several different databases and what if I decide to make like 2 more columns in player database

[hazy parrot]

you add two more getters

adding 2 more columns isn't something you gonna do every day

[lost matrix]

Have you looked into saving your data to files?
If you havent, then you should def consider it instead of using a database.

[storm crystal]

yall literally just told me that its a fucking bad idea to do it in config files 😭 😭 😭

what the fuck

I dont know at this point

[lost matrix]

Just came here. Saving data to files is a totally valid approach.
And again: Different people can have different opinions. I dont understand why this shocks you every other day.

[storm crystal]

because by the moment I am 1/3rd in finishing something someone told me to do

someone else tells me to do the other thing

[river oracle]

I think you're too reliant on advice here tbh if it changes the direction of your entire project

[lost matrix]

There are formats which are more viable for data storage, like json.
Yml is also fine, but i would def consider it a configuration format.

[storm crystal]

I want to make database (OR WHATEVER) to store player stats, enemies to spawn, weapon data etc.

[river oracle]

This exact thing has been said multiple times yet we keep having this convo for some reason

[knotty aspen]

just store everything as binary blobs in a file

alternatively, do the Wynncraft and store things in a chest at a specific position in the world

[lost matrix]

Is this project meant to run on multiple server instances at once?

[storm crystal]

what?

[lost matrix]

Do you plan on having multiple spigot instances running in parallel?

[eternal night]

Do you plan on having Highscores

Or generally any cross player data gathering

[storm crystal]

I dont know

I dont know if what I want to do will need it or not

[lost matrix]

Matters if he has more than a few k unique players really.
But also something to keep in mind

[eternal night]

I mean

Meh XD

If you wanna just smack JSON into places

Mongo ?

[lost matrix]

If i expect <1k players then i just sacrifice 50MB ram and dump everything into memory

[river oracle]

muh Memory NOOOOo

[knotty aspen]

tbh if you don't know what you want, stick with something simple like json/yaml and files

if you don't know if you need a DB, you probably don't

[eternal night]

Can always move into a DB Lager

Later

[lost matrix]

Hmm Lager

[eternal night]

Keep your logic abstract enough to switch down the line

[storm crystal]

I want to make database for:

• players: custom base attack, armor, resistances, deaths, money, etc.
• lootboxes: items, item datas, odds
• weapons: custom statistics, special things like PDCs
• enemies: health, armor, attack, drops, level scaling etc.

thats just it

[lost matrix]

Honestly, i think you will be fine with files for all of those.
Databases add a layer of complexity and might not benefit you here.
Pretty much everyone started with saving their data to files, i still do it for
some projects, and i recommend you doing the same.

[storm crystal]

and people told me here that its an awful idea to have stats that would change constantly be saved into files

and I already bothered to download xampp and start rewriting my plugin

[lost matrix]

The frequency at which data is changed for only online players is pretty much irrelevant for your choice of persistence.

It only matters if you take the accessibility of your data into account.
For example top lists, or computing statistics, etc (Or scaling way beyond what the average mc server needs)

[grim hound]

It's not

I just save it async at world save event

And it works just fine

Just remember to have the file write synchronized

[storm crystal]

well fuck this shit ill do it in mysql just to be left alone at last and make it work

[grim hound]

Do you have a mysql server?

And is it for public use?

[storm crystal]

why would it be public

[grim hound]

Cuz this is all fuqin

Plugin development

And mostly public ones

[storm crystal]

database is only for me

lol

[serene sigil]

hi guys how to make it so the minecart doesnt stop when the player stands on the rails?

it should keep its velocity

[molten hearth]

alr so i already asked this earlier but id like to know if anyone else has input on this, what would be a good way to know if a player broke a block with PlayerInteractEvent

[young knoll]

Uhh

Check if the block they click is instant breakable I guess

[torn badge]

What are you trying to do?

[molten hearth]

im cancelling an interact event when left clicking a block bc i have some custom beheavior when a noteblock is punched (beheavior that conflicts with vanilla beheavior)

but i still want the noteblocks to be breakable

[torn badge]

I mean at the time InteractEvent is fired you don’t know if the block will be broken since the player can just stop before

[molten hearth]

yeah well thats my issue

because blockbreakevent wont fire if interact is cancelled

[storm crystal]

https://www.spigotmc.org/threads/how-to-sqlite.56847/ I found this post about using SQLite as database, from what I understand it makes database (.db files) in server files and requires no external database working in background

[torn badge]

Could use shift click to differentiate

[storm crystal]

could this also be useful to what I want to do?

[molten hearth]

yeah well i dont want to force players to break them by shift clicking lol

[storm crystal]

well using this SQLite method + caching it to not lose any data

[torn badge]

If you don’t plan on using that data from multiple servers simultaneously yes

[storm crystal]

when would I want to use several servers at once?

I mean

how big of a project would it have to be?

[torn badge]

If you have a network and need multiple servers to access the data

[storm crystal]

I just want to make a rather smaller mmo rpg styled server

not anything super huge

[torn badge]

What exactly is your custom action?

[torn badge]

SQLite is fine for that, you can still pretty easily migrate to MySQL later if you need to

[storm crystal]

okay thats pog

would you still recommend caching data even if it was locally in server files under .db files?

[torn badge]

Depends on query complexity, caching is always a good solution if you have very heavy queries or data you use frequently

[storm crystal]

id use data pretty much all the time

[torn badge]

And consider handling your queries asynchronous

[storm crystal]

to spawn mobs, get weapon statistics and such

[warm mica]

You can cancel the NotePlayEvent if it is getting called during the same tick as the interact event (World#getFullTime())

[torn badge]

But don’t forget that any thread will lock the file until it has finished its operation

[storm crystal]

do you have any resources on setting actions async?

[torn badge]

Any Java Multithreading explanation should help you out with the basics

[molten hearth]

well i removed the feature from noteblocks to change notes when clicked

so i manually play the notes using some block pdc

[storm crystal]

okay

[molten hearth]

cancelling noteplayevent does not cancel note increments

[lost matrix]

https://www.spigotmc.org/threads/guide-to-async-io.623371/
https://www.spigotmc.org/threads/working-with-data.562421/

[storm crystal]

Thank

[warm mica]

Of course they don't. In that case cancel the right click within the interact event. But you have been asking for left click

[lost matrix]

You should never, ever do any IO on the main thread

Also: Always throw away (and close) your connections. Get a new connection for every single request.

[ivory sleet]

(Except startup and shutdown :>, then it can be fine)

[lost matrix]

Yes, mr clube is right

[ivory sleet]

mr smiley is just as right :)

[lost matrix]

As long as your closeConnection method checks for null values, this looks ok

https://www.spigotmc.org/threads/guide-to-async-io.623371/

[young knoll]

Try with resources best

[river oracle]

@sterile axle I'm curious about something why does my char array need to be 5 here to capture the entirety of the word exit shouldn't that take up 4 positions within a char array
0: e, 1: x, 2:i, 3:t

  char input[5];
  while (strcmp("exit", input) != 0) {
    printf("command: ");
    fgets(input, 5, stdin);
    printf("%s\n", input);
  }

However, if I use only 4 the array gets cut off and the output looks like

command: exit
exi
command: t

when expanding to 5 the array works as expected

command: exit
exit
command: 

[lost matrix]

C or C++ ?

Looks like pure C to me, right?

[river oracle]

its pure C

[lost matrix]

Your strings are terminated by a null character

[river oracle]

? explain further

why exactly

[sterile axle]

strings are terminated by \0

[lost matrix]

Its like a memory address which signals that the string ends here. '\0'
Strings in C are terminated with it so you can have a pointer to the start of your character array, without
having to know its length. You simply traverse the memory block until you hit the null character, which terminates the string.

[sterile token]

I need some help about a school project which i have some doughts about its designing. At momment i have done the next things basic things for it https://paste.md-5.net/yuhoqajile.java. I would be really thankfull if you can take a look at it. Its somethign really simple and without much effort hehe

[sterile axle]

Java strings are also null terminated but it handles it transparently and you never have to worry about it

but C does not do that for you

it's how it can tell that the string is over

[young knoll]

Reminds me of gameboy assembly

[sterile axle]

strlen for example goes char by char and increments a number for each char it sees, infinitely, until it finds \0

[young knoll]

Lots of terminator characters there

[sterile axle]

if it doesn't ever find \0, that loop won't stop until it reads memory it doesn't own

[river oracle]

ahhh okay

[sterile axle]

then you segfault and program crashes

[river oracle]

I forgot strings are just char arrays for some reason

[sterile axle]

printf("%s", stringhere) will print char by char until it finds \0. if it doesn't find one it'll keep printing each memory address forever until it reads and tries to print memory it doesn't own then your program crashes

[young knoll]

Java strings are byte arrays

Extra fancy

[lost matrix]

Doesnt look too bad at first glance

[sterile axle]

strings in any language are arrays of chars, it's just an abstraction around that. you either have a char array and a length to know how long the array is, or the array is null terminated so you can tell the array is over

c just doesn't do anything for you

you do it yourself

[young knoll]

In the original Pokémon games your inventory was terminated by a special byte

[sterile token]

Im missed up between the return null from the obtain user method, not really sure how doing it that part. Could you giveme a small hand. And thanks for reviewing my code

[slender elbow]

pascal strings best

[young knoll]

If you got rid of the byte somehow you got to see arbitrary data as items

Yay

[sterile axle]

mc protocl also uses length-prefixed strings which is interesting

<length>char,char,char,char,char,char,...

[lost matrix]

Wait i got a meme saved somewhere for that. let me see

[slender elbow]

char,char,binks

[sterile axle]

anyway @river oracle this isn't just strings, you will also find this pattern any time you want to have an array of something you don't necessarily know the length of, you just put your shit in the array and then add a \0 at the end, and when looping you'd do something like ```
while (*array) {
//use the element
++array;
}

and when you hit the \0, the loop ends

or you have two params, the array and size and you can use a for loop

common C patterns

[slender elbow]

need to dereference for the condition but yeah ^^

[sterile axle]

oh yea forgot that

[lost matrix]

++array for saving that one clock cycle 🤓

[sterile axle]

C has ruined me

[slender elbow]

but what if I'm on a CPU with a really bad instruction set and the difference is 17 cycles

what can i return in the next method? Because null cant be returned because the method is used on my user signup method

[lost matrix]

Something something mov eax -> add eax, 1 -> mov back. Idk i kinda slept through x86 instructions

[slender elbow]

movfuscator to the rescue :kappa:

[lost matrix]

Just handle null values?
Or wrap everything into Optionals

[sterile token]

the problem is the next

[lost matrix]

...

[sterile token]

sorry cellphone dc is wrokign for the ash

[lost matrix]

if(result == null) {
  return null;
}

?

[sterile token]

i cant return null

because i use the obtain method on top for handling user losgin

[sterile axle]

throw an exception then. if it's null, it's null. you have no choice but to try again or give up and print and error message.

idk what you want

[sterile token]

let me explain ok?

[sterile axle]

you want to magically say "oh i got null", "but nvm I don't want null"

"let me just pretend it didn't happen here is ur resultset"

[lost matrix]

Handle possible null values then.
You dont need this to be in an ternary op

[sterile token]

the user shouldnt be null at the login part, thats to begin

[sterile axle]

i am so confused what the issue is

[lost matrix]

Then throw an IllegalStateException or something

[lost matrix]

Same

[sterile axle]

this is basic error handling, if it cannot be null, and you cannot return null, but it's null anyway you got a problem

throw an exception

that's what exceptions are for

[slender elbow]

An exception that signals something was null, even

[sterile axle]

heh

[lost matrix]

-.-

[sterile token]

i just dont know how to proper explain myself

[sterile axle]

use chatgpt and write in your native language and tell it to make an explanation in english then

[young knoll]

You could just kill the jvm

Always a good option

[lost matrix]

System.exit()
And no further explanation

[river oracle]

I would go for a more elegant appraoch

System.exit();

fuck Smile beat me to it

[lost matrix]

hehe

[sterile token]

Frame#dispose() better idea

[sterile axle]

me in C:

"o fuk my pointer is NULL."

exit(1)

[lost matrix]

Oh yeah. Bind a dll and call it via JNI. Just set your whole jvm mem to 0x0

[sterile axle]

easy

[sterile token]

why you trolling me? i was trying to get helped

[sterile axle]

but seriously if you can't explain yourself, then go write to chatgpt your entire message in your native language and say "translate to english" and it will do a much better job than you are doing

and then we can probably help you

maybe

[raw epoch]

hey i'm trying to prevent Creative player to move items from their inventory but the creative mode duplicate items when the event is cancelled, does anyone has a solution ? Thanks !

[sterile axle]

but from what you are explaining, to my understanding, you have an object that should not be null, but you're worried it's null anyway. so check if it's null, if it is, you know you're in an illegal state, throw an illegal state exception or something

that's all you can do, you can't just magically recover

[lost matrix]

What prevents you from doing this:

    public boolean signin(String email, String password) throws SQLException {
        User user = this.users.containsKey(email) ? this.users.get(email) : obtain(email); // Can return null
        if(user == null) {
          return false;
        }
        return user.getPassword().equals(password);
    }

[young knoll]

What’s the unsafe call to destroy the jvm

Kek

[lost matrix]

[river oracle]

pretty sure that is Client side? correct me if I'm wrong, but I'm pretty sure its not possible to prevent on the server

[raw epoch]

hmm you're maybe right

[river oracle]

Creative mode is weird

[young knoll]

Yeah creative is mostly client side

Maximum jank

[river oracle]

it doesn't like telling the server what its doing

[lost matrix]

Or if you need a more granular response: Create an enum.

    public enum LoginResult {
        SUCCESS,
        UNKNOWN_USER,
        WRONG_PASSWORD,
        ALREADY_LOGGED_IN
    }

    public LoginResult signin(String email, String password) throws SQLException {
        User user = this.users.containsKey(email) ? this.users.get(email) : obtain(email); // Can return null
        if(user == null) {
            return LoginResult.UNKNOWN_USER;
        }
        if(user.getPassword().equals(password)) {
            return LoginResult.SUCCESS;
        } else {
            return LoginResult.WRONG_PASSWORD;
        }
    }

[lost matrix]

Change this field via reflection

And ignore the comment 🙂

[wary harness]

how to fix this

Bukkit will attempt to fix it this time for you, but may not be able to do this every time.
If you see this message after typing a command from a plugin, please report this to the plugin developer, they should use the api instead of relying on reflection (and doing it the wrong way).```
I used this code for years

[lost matrix]

Spigot has an API for that

[wary harness]

from when

[lost matrix]

Idk. 1.16.5 ? 1.17. Something like that

[exotic obsidian]

hello

"statement.close();"

is it important?

[lost matrix]

Depends. Only if you want your server to run properly.

[exotic obsidian]

some programmers don't used it

so that's why i'm asking

[sterile axle]

if you wrap the prepared statement in a try (PreparedStatement stmt = ...) {} then close() is called automatically

Otherwise you need to call it, or you leak connections

If others are not using it and are not using try-with-resources (above) then they are coding incorrectly

[lost matrix]

In honesty it is specific the the underlying implementation.
But i dont think there is any decent porgammer which doesnt close or auto-close this.

[sterile axle]

porgammers rule

[paper viper]

Woah, new orange helpers?

[lost matrix]

As simplyauthority suggested: You have probably seen code where a try.with.resource block was used.
It automatically closes resources like connections when a scope is left.

[young knoll]

Pretty sure the profile api was 1.18

Man JEPs hurt my brain

[slender elbow]

can't hurt when you don't have one

[wet breach]

It can be. Do note that statements will close automatically after a period of time

[young knoll]

:(

[wet breach]

The downside is until the system closes it, those jdbc resources are now occupied and not free for something else to use it

[young knoll]

I just want to determine if/when a feature is finished

Gotta follow a trail of endless links smh

[wet breach]

So it is good practice to close out resources once you are done with them

[slender elbow]

eh, "it depends"

[wary harness]

Profile thing is not working @lost matrix

@river oracle funny coincidence. C23 apparently added bool, true and false as keywords apparently. so importing stdbool would have done nothing at best and at worst would have conflicted with the actual keywords

I'm attempting to update a very old plugin to work with modern Spigot versions, and before I understand how the plugin works, I want to just update it as-is. The problem is, it uses a whole lot of NMS (which I will remove in future). The issue I'm running into is, I've configured maven to use the remapped spigot.jar, but the functions aren't being properly remapped, and I'm a little out of my depth.

It's using the right file, reportedly. Just.. the file doesn't have the right mappings?

[weak meteor]

yo

so i wanna check if args of a command are empty or not, so lets say the command is /ik create <name> <slot> right?

[balmy hull]

I'm using nms to make a custom projectile entity, and use bukkit for most of my other effects for the entity. When I create an instance of the entity class in my effects class, the methods it inherits from class WitherSkull nor the methods i've created appear as hints/suggestions and I'm wondering whether this is an ide error conflicted between similiar methods with bukkit and the remapped nms methods, anyone got any ideas?

[weak meteor]

so, if name is not given

how do i check?

args[1] != null doesnt work

[sullen wharf]

.isEmpty?

No wait

[remote swallow]

args.length == 2

[sullen wharf]

Ye that

[weak meteor]

AH

yea

thanks

[sullen wharf]

Check for lenght < arg number

[weak meteor]

I never understood completely how to use Gson and well, create, edit, and delete .json files, where can i see a good forum post or yt tutorial?

Another question

if im making a Kits plugin, whats the best way to represent the kit, a class or interface?

Cause, multiple plugins use interfaces to represent players, factions, etc.

[exotic obsidian]

Sry xd

[wet breach]

I would probably have an interface as a base that can be extended to encompass the various kits. It makes easier later to identify who has what kit and you could use casting if necessary to do whatever it is you need

So categories of kits is what i meant not the individual kits and then have a config setting for setting a kits category

[eternal orchid]

is there a way to cancel a player's shield blocking an attack?

[quaint mantle]

is there a shield disable event?

[eternal orchid]

dont think so, i managed to solve it by setting the BLOCKING DamageModifier, which is deprecated

[quaint mantle]

yeah im just using the PlayerStatisticIncrementEvent for it

[thorny pendant]

When using itemsadder or oraxen, how do I keep my FPS from dropping when I'm surrounded by custom furniture?

[torn shuttle]

so you want to start off by purchasing mojang for about 8 bil usd, then you want to rewrite minecraft java edition from scratch and finally you will want to push that update out for everyone to be able to enjoy at a reasonable framerate

[thorny pendant]

Is there a better way, I noticed they are all armor stands

Lots of armor stands keep my FPS down

[torn shuttle]

better?

yeah

so little known fact you can also just buy the parent company, microsoft, and then change the OS for windows to be more performant such that when you play minecraft on it you will get even more fps

I don't exactly know how much the market price for buying microsoft nowadays is though

[thorny pendant]

I'll call the CEO of Microsoft. I'll buy his company by next week.

[torn shuttle]

next week? You really shouldn't be living paycheck to paycheck like that

chatgpt says you should be looking at about 2.5 trillion usd to buy microsoft so you might have to cut back on the caviar for a couple of days if you want to buy it

[knotty aspen]

if those plugins used display entities instead of armor stands you could just set proper culling values and that would improve FPS

so its not like Mojang needs to fix that, those plugins just need to use the stuff mojang made for this specific usecase lol

[torn shuttle]

to be clear mojang should definitely be looking at ways of optimizing idle entity overhead

it's really bad

[knotty aspen]

well, for ticking entities yes

but 1800 display entities at once def work without any major performance issues

[torn shuttle]

I ran benchmarks yesterday, server-side I can handle about 14000 ticking armorstands but client-side my insane cutting-edge desktop build starts getting stuttering drops with about 1k entities

[knotty aspen]

the client will try to tick all those armor stands, so yeah

[torn shuttle]

it's not good

[knotty aspen]

doesn't help they are living entities because mojank

[torn shuttle]

hence me saying they should be optimizing them

[knotty aspen]

but 1800 display entities are doing fine (video from bergerkiller, not me)

[torn shuttle]

well I made my system to try to be entity-agnostic where possible so I will be trying it out with display entities real soon

[knotty aspen]

they are so much nicer in absolutely everything tbh

And you usually need less of them because you can transform them freely

[torn shuttle]

she's a beaut

how would you need less of them

you still have the same bone count regardless

unless you mean they can handle large scales

[bitter rune]

does this generate any number between 1 and 100 ? double lottery = random.nextDouble() * 1001;

1000*

[knotty aspen]

depends on what you are doing, for bones its probably not helpful

but I am doing entity models and animations completely clientside with shaders at this point tbh, way easier

[torn shuttle]

with shaders? I'm assuming you're modding then

[knotty aspen]

no, vanilla shaders

[torn shuttle]

how does that work?

[knotty aspen]

https://github.com/Godlander/objmc

basically this for the client with a server resourcepack and a plugin to control animations and stuff

only downside is enabling shaders in Iris/optifine will break the animations. but its a PvP server so people really don't play with Optifine/Iris shaders that much

[torn shuttle]

how does this work then, is there some kind of resourcepack thing that alters shader behavior?

[knotty aspen]

vanilla has shaders since 1.17. and with a shader, you can change how things are rendered. this basically puts the entire model in a texture, and uses a shader to render a model from that texture

[torn shuttle]

how does the client decode the textured model into something that results in a 3d object in the game? I assume you'd have to pass some kind of custom interpreter to the clients at some point

[knotty aspen]

well that is what the shader is doing

[torn shuttle]

well yeah but how are you distributing that shader

to the client

or is it built around a vanilla shader somehow

[knotty aspen]

The shader is part of the server resourcepack

"shader" isn't just shadows on the ground as its often used in minecraft context, its just a part of the rendering pipeline. You can also do things like turn the screen upside down, render portals like in the Portal games, etc

[torn shuttle]

I've written some shader code before, I am aware

I was just wondering if it was even possible to pass custom shader data via rsp

didn't know it was

[knotty aspen]

yeah its kinda undocumented, classic mojang feature

[torn shuttle]

so does that override the default shader insantly?

[knotty aspen]

yeah

[heady wasp]

hey everyone, i'm trying to store locations in a .yml file and also read them as a Location. i'm a little confused on this.

[torn shuttle]

that's kinda whacky

I assume you're sort of limited in bone control though, right?

[heady wasp]

https://cartyoo.org/images/47951.png this is the output idk why it is like this

[torn shuttle]

since it's client-side

[knotty aspen]

passing data to the shader itself from the server is a bit tricky, but using a colored item like a potion works

yeah I am not doing any individual bone control and thats probably also not possible

[torn shuttle]

yeah figures

anything even close to touching ik would be either insanely hard to pull off or straight up impossible

[knotty aspen]

Main use case are siege weapons, so I really only need to do play and stop an animation

they don't exactly walk

[torn shuttle]

yeah I mean this is honestly an insane system for a lot of unique applications, it breaks a lot of set conventions for mc

fortunately it doesn't really invalidate the work I've been doing on my own end since mine focuses on applications where you do need very precise bone control

[knotty aspen]

main issue (and probably not really fixable) is that both Optifine and Iris will overwrite vanilla shaders if you enable their shader stuff

[torn shuttle]

yeah no you're screwed on that one for sure

and it's a shame too because stuff like OF is pretty popular

[knotty aspen]

And vanilla shaders are limited in some ways right now, so for actual fancy rendering optifine-compatible shaders are superior

Like I am not even sure you can get the sun position lol

[torn shuttle]

buddy

what sun

there is no sun

what do you think this is, pbr with directional lighting?

[knotty aspen]

well, there is a time of day

[torn shuttle]

get outta here

it's all global illumination with a basic code that crawls from the top of the world to the bottom to set brightness levels

there is no concept of a sun

[knotty aspen]

there is PBR though

Complementary with Iris has PBR

[torn shuttle]

the only pbr vanilla minecraft devs know is pabst blue ribbon at the end of a work day

[exotic obsidian]

Hello

[knotty aspen]

You really don't like Mojangs work lol

[torn shuttle]

it's not a criticism

I don't think mc looks better with pbr

I do wish it had better lighting though

and performance

if I liked pbr I'd use a shader that either uses or emulates that effect

[knotty aspen]

its only something I use for screenshots. all those fancy graphical effects annoy me otherwise

[torn shuttle]

same, pretty much

if I had an infinite amount of time I'd go and make my own custom shaders that are more soft toon shaders than pbr

those work better with mc in my opinion but it takes a lot of work to get them just right

[exotic obsidian]

How can i save player data like kills, death in hashmap then transfer it to database?

[pastel axle]

I'm starting to understand my issue a little better. Why are the class names different for remapped-mojang vs not? I thought it was just function signatures and such?

If I use remapped spigot, net.minecraft.world.level.chunk.IChunkProvider doesn't exist. If I use standard spigot, it exists but has obfuscated function names.

[proud badge]

are SQL injections possible within the minecraft chat

[dry hazel]

yes, spigot mappings don't have member names anymore

[pastel axle]

Hmm, what do I do in that case?

[dry hazel]

just use mojang's mappings

if you want to convert from spigot to mojang names:

?mappings

[undone axle]

Compare different mappings with this website: https://mappings.cephx.dev

[warped shell]

is it ok to backup a server while its running?

i plan to use tar and pigz to backup a server once per day

[wet breach]

Depends what exactly you are backing up. if it is just world files sure as long as you disable world saving. I have a script that is setup where you can just make a cron job if you want to look at it. Does other nifty things and i have alternatives too

[warped shell]

why is world saving an issue? is it file access between threads?

here is my bash for saving

timestamp=$(date +"%Y%m%d_%H%M%S")
backup_filename="backup_${timestamp}.tar.gz"
num_threads=6

cd "$source_directory" || exit

tar -cf - . | pigz -p "$num_threads" > "$destination_directory/$backup_filename"

echo "Backup completed at $(date)"

find "$destination_directory" -name "backup_*.tar.gz" -type f -mtime +21 -exec rm {} \;```

[wet breach]

Because if you tried backing up a file that is in use because the world is saving you wont get the updated info or you end up with mangled info which can cause chunk corruption

[wet breach]

https://gist.github.com/frostalf/74d662a4bf381ad4ba2679bc537c4595

When i get home i will look into updating it to add backup command

[old cloud]

Is it possible to dynamically listen for events? I Wonder how the skript plugin does it because it doesnt know which events it will Need beforehand

[wet breach]

Skript basically translates. But events work because plugins have to register their listeners. Skript uses some generics to do this and does the registering.

[old cloud]

So does it register all the Events?

[storm crystal]

https://youtube.com/shorts/00U1nOAvQcY?si=FOUF5mv2Qy4-PU_h

She wouldnt know that

💀

[wet breach]

No. Just only the ones that the skript needs

[old cloud]

So how does it do that dynamically?

[wet breach]

Skript itself is a spigot plugin made in java. Skript scripts are what interface with skript plugin and tells it what it needs. All the skript plugin is doing is playing middleman between two languages

[old cloud]

That wasnt really my question

[wet breach]

There is nothing that says listeners have to be registered at startup. You can register later if you want and unregister as well

But skript also uses generics too

[old cloud]

Yes but how would you dynamically create a class that contains a Methode that does what was defined in some textfile

[wet breach]

Generics

As i keep saying

[old cloud]

…?

Still dont know how

[wet breach]

Generics lets you take in objects of unknown type and do something with them

[wet breach]

Well probably something worth researching to get a better undetstanding

[old cloud]

Yes but still dont know how this helps me achieving the thing

[wet breach]

Cant achieve something you dont understand so you have some learning to do 😉

[old cloud]

lmao 😂

So you cant help me alright

[wet breach]

Its not that i cant help. Generics is not something i can teach in 5 minutes

[old cloud]

I know what generics are.

[wet breach]

Its like its own topic in java itself lol

[old cloud]

The point is that i dont understand how this would help me achieving

Because generics is where java derives some of its dynamics from

[storm crystal]

Being a paranoid purist doesnt help you either :|

[torn shuttle]

I find that it has, tremendously so, you should try it out

A method that uses generics can take an arbitrary object of unknown type and do something with it. All events in the api extend from event.

The unknown type part is where the dynamics come in as you dont necessarily need to know what event just that it is one

You can figure the type out by checking it against the event types until one is true

Now you have your type

[storm crystal]

Well you started freaking out the moment someone sent you one 🤷‍♀️

[wet breach]

Then you would have a general listener class that you create new instances of feeding it your now gathered info

And then register it

Now this is obviously an over simplification of the process.

[torn shuttle]

ah it seems as though I have played myself

I forgot this encrypted volume was like 4tb large

[wet breach]

Lol

[torn shuttle]

yeah so updating its encryption is going to take... a while

[wet breach]

It would be faster if you have another 4tb volume

Then its a simple transfer

[torn shuttle]

it would be faster to encrypt, it would not be faster to transfer

the transfer speed is shockingly slow

to be clear this is a vm

[wet breach]

Why is the transfer speed slow?

[torn shuttle]

what a great question

[wet breach]

You can speed it up by mounting the vm file on the host

[old cloud]

Thankyou @frostalf

[torn shuttle]

it's a mix of how the files are transfered and what files i'm transfering

because files are fun this is basically tranfering them one by one but also encrypting them one by one, and this is mostly millions of tiny files

maybe tens of millions

[wet breach]

Why are you not using drive encryption?

[torn shuttle]

and I can't buffer them into a zipped file because, well, you know, that would be another 4ish tb of buffer I would need on a bunch of different places

you mean encrypt the entire drive?

[wet breach]

Yeah

[torn shuttle]

it's an 11tb drive I'm using for more than just that vm

hell at one point it wasn't even the only vm on that drive

[wet breach]

Its a vm so why are you stuffing everything onto a single drive when you can have as many drives as you want

[torn shuttle]

I'm not stuffing everything into a single drive

I have something like 25tb of storage

[wet breach]

Well obviously your setup is flawed somewhere lol

[torn shuttle]

how's that?

can a man not have a 4tb vm?

[rotund ravine]

Lol

[torn shuttle]

I'm pretty sure that's the 21st ammendment

[valid burrow]

sounds reasonable to me

[wet breach]

I have about as much storage space as you do and tranaferring large bits of data takes me a couple minutes even inside a vm

[torn shuttle]

inside a vm is fine, it's from an encrypted vm to my os when it's for, say, 11 million individual files that things start getting spicy

[wet breach]

The hdd file can be mounted on the host without the vm just fyi

[torn shuttle]

but I do agree that I might be doing something wrong with my vms regardless, more often than not I get glacial performance out of them

[wet breach]

Also vms can make use of hardware directly

That means it doesnt need a virtual hdd

[torn shuttle]

I have tried just about every option that is available to me in vmware

[wet breach]

Which is where you probably went wrong when it comes to large data lol

You obviously didnt setup a discrete volume on the host hardware for the vm. If you did your transfer speed would be faster as the vm isnt emulating hdd hardware

[torn shuttle]

you mean like partitioning my hdd so that that gets assigned to the vm alone?

[wet breach]

That would have been ideal

[torn shuttle]

yeah no I didn't do that

I mean I'm fine with it, somehow every other time I open this thing I end up adding another tb to it so I don't want to deal with resizing partitions every few months

[wet breach]

Dont have to do that either. You can just let the vm access hdd directly to save stuff keep vm os in its own vm hdd

[torn shuttle]

guess I'll maybe look into that in a year when it's done reencrypting

[wet breach]

Lol

[torn shuttle]

the progress bar actually moved, shocking

[wet breach]

🤔

[shadow night]

What's going on here

[wet breach]

Better hope no power failures happen lmao

[torn shuttle]

yeah was thinking the same thing

thank god I don't live in south africa right now

meh everything in these is discardable anyway

[wet breach]

Do you have a battery backup?

[torn shuttle]

nah I should get one some day but honestly in the last 10 years there have been 3 power outages

[shadow night]

Tf ya guys talking about

[wet breach]

Nice

[torn shuttle]

only a single time did an outage take more than 2 minutes

[wet breach]

Yeah power failures for me are rare too

[torn shuttle]

the rest were just instantly out and back

I think it was maybe 4 minutes for the longest one

[wet breach]

But i had a power failure take a hdd with it though

[torn shuttle]

I am really playing russian roulette for the outages because every time I basically have to guess the encryption passwords for my NAS

[wet breach]

Because the power surged like 3 times which over loaded my surge protector just enough

[torn shuttle]

if it goes down I'm not sure I can get it back up lol

I should write that one down and put it in my safe

[wet breach]

Lol

[wet breach]

Tech stuff

[shadow night]

Well

Tech stuff can be from nothing to anything

[wet breach]

Indeed. I just didnt want you to feel ignored

[shadow night]

Well, nice

Thanks ig

[wet breach]

Magma has a weird vm setup and is decrypting 4tb transferring it and rencrypting it

And its taking forever for him

[shadow night]

The only vm I have is the ubuntu one hosted on my laptop that I use to do stuff with mcp lol

[wet breach]

So o told him an alternative setup that could speed stuff up and then said pray you dont have a power failure

Think that sums it up

[shadow night]

Power failure would be ass

But isn't that pretty rare

[rotund ravine]

Depends on ur location i guess

[shadow night]

Well, here it's rare

[bitter rune]

someonemine mind looking at my save and load and seeing why some of my values arent saving? when others are

[rotund ravine]

my currency variable isnt being persistent on relog, or server restart, but if i just quit out of the game it saves correclty to file... here is all the java files associated with it

https://pastebin.com/hBmY9YLL

[lost matrix]

Show your join and quit events pls

[bitter rune]

https://pastebin.com/sJBkH9hW

[lost matrix]

Not the problem but delete this line

OfflinePlayer offlinePlayer = Bukkit.getOfflinePlayer(player.getName());

[rough drift]

Should I use a StringBuilder here instead of just directly typing the query (the data is controlled, no user input, easier to use a StringBuilder)

[lost matrix]

Ok so your data is saved when you quit, but not when the server stops?

[bitter rune]

no, its when i log back in and increment the variable again it resets

everything else is persistent, and i am pretty sure its saving just like everything else so dont know what gives

[lost matrix]

Debug your load and save method. Make sure they get fired and that if (dataFile.exists()) { is true.

[upper hazel]

how itemsAdder creates custom blocks in caves without creating a problem with armourstand dimming

[young knoll]

Noteblocks im pretty sure

[upper hazel]

there are 3 types of blocks and one of them creates an armorstand

in wiki

itemAdder

[lost matrix]

They create a spawner. Inside the spawned entity is displayed.
They stop it from rotating, set a block in its head and scale it so it barely covers the spawner.

Thats how it was done a while back.

[upper hazel]

With the help of notes you can create 25 custom blocks and itemAdder offers more

[round finch]

this might be a back to java moment but...
my question is: how do you use interfaces and what is it for

i could google it but i just wanted to hear

[upper hazel]

is the element inside the spawner an ItemStack?

this is why itemAdder can create 3d texture?

[young knoll]

Noteblocks have way more than 25 states

I think it’s near 1000 now

[upper hazel]

and is it really possible to expand the texture?

[upper hazel]

1.16.5

[young knoll]

Should still be quite a few

Noteblocks have 850 states in 1.16.5

[upper hazel]

I checked when I clicked on the block. after the 25th attempt the note returned to position 0

[young knoll]

1150 in 1.20

Yeah but you have all the different instruments

And also powered/unpowered

[upper hazel]

different noteBlocks?

[young knoll]

17 instruments x 25 notes x 2 powered states

(23 instruments now)

[wet breach]

When server restarts there is no quit events. You need to have a save method in onDisable()

[upper hazel]

and how to get them? I've only seen 1 in minecraft

17 different noteblocks

use 1 texture?

[hybrid turret]

If I understand the code in JavaPlugin.java right, shouldn‘t there be a warning everytime I restart/reload my server and the config.yml already exists?
(JavaPlugin 217:17)

[upper hazel]

and 1 model?

[young knoll]

They are all states of the same block

And yes they all use one texture

Change the instrument by changing the block below the noteblock

[upper hazel]

oh

[wet breach]

Isnt there more states for some of them just not used?

[young knoll]

Or in the case of plugins you just spoof it

[lost matrix]

An interface is for defining a behavior. For example:
This interface defines a behavior. X goes in, Y comes out.
But we have no idea what the actual implementation is.

public interface BlockDestroyer {
  void destroyBlock(Block block);
}

At this point we can already use this interface.

  public SomeListener(BlockDestroyer destroyer) {
    this.destroyer = destroyer;
  }
  
  private final BlockDestroyer destroyer;
  
  @EventHandler
  public void onClick(PlayerInteractEvent event) {
    Block block = event.getClickedBlock();
    if(block == null) {
      return;
    }
    this.destroyer.destroyBlock(block);
  }

We simply use this interface, and trust that the implementation does what we expect.
At this point we dont need an implementation. But as soon as we want to create an instance, we need to pass some BlockDestroyer.
Here are two simple implementations for our earlier behavior.

public class BlockExploder implements BlockDestroyer {
  @Override
  public void destroyBlock(Block block) {
    block.getWorld().createExplosion(block.getLocation(), 5.0F);
  }
}

public class BlockVanisher implements BlockDestroyer {
  @Override
  public void destroyBlock(Block block) {
    block.setType(Material.AIR);
  }
}

Our implementations can then be used and we can swap them out depending on what we want

  @Override
  public void onEnable() {
    BlockDestroyer destroyerA = new BlockExploder();
    BlockDestroyer destroyerB = new BlockVanisher();
    
    Bukkit.getPluginManager().registerEvents(new SomeListener(destroyerA), this);
    // or
    Bukkit.getPluginManager().registerEvents(new SomeListener(destroyerB), this);
  }

[young knoll]

Nah that’s all of them

[upper hazel]

so does the environment change notes?

[young knoll]

850 states in 1.16, 1150 now

[wet breach]

Not that i am aware. Just the right clicking of them and whatever blocks are under them

[upper hazel]

that is, depending on the environment, the note block will change?

and also this is why more than 25 notes

hm

This means that at the moment there are 3 ways to create blocks with custom textures. These are note blocks, spawners, armor stands?

[young knoll]

In 1.16.5, yeah

[wet breach]

Sponges

[young knoll]

Sponges?

[lost matrix]

Display entities

[upper hazel]

and more frames

[wet breach]

You can replace them if you want for custom blocks

[young knoll]

No display entities in 1.16 :p

Why sponges

[lost matrix]

Oh we on 16

[wet breach]

Because they are typically not useful

[young knoll]

Sure but

[lost matrix]

lol...

[young knoll]

Wouldn’t be my first choice

[upper hazel]

not in anarhy server

when you create base sponges really need

[wet breach]

Historically it was the go to block to swap out for custom blocks

[young knoll]

Well yeah because they used to be unused

They aren’t now

[hybrid turret]

Ping me on an answer plez :)

[wet breach]

Could even use barrier block for custom blocks

[upper hazel]

in servers the barrier is very limited

so you can see

this barriers

[young knoll]

Leaves and tripwire also have a bunch of states you can use

[upper hazel]

hm

[young knoll]

Leaves for transparent custom blocks and tripwire for non solid blocks

[round finch]

someone should ping this

great exemple

[upper hazel]

polymorphism baby

[upper hazel]

this too

all oop this polymorphism

[round finch]

thank you @upper hazel

``i just learned a few days ago it was possible to do someting similer to this...

Creeper Creeper = (Creeper creeper) -> Creeper.SomethingMethod()``

[lost matrix]

❓

[shadow night]

looks like a lambda of some kind

[glad prawn]

Creeper is functional interface?

[round finch]

trying to find the exact code

but it was along of the lines of that

starts ecplise

[wet breach]

int i = (int) (Integer) get()

[round finch]

more mindblowing stuff

[lost matrix]

What are you guys saying??

[wet breach]

That is equivalent to this

int i = ((Integer)get()).intValue()

[round finch]

what i saw was spigot related

[eternal night]

[round finch]

to some entity

[young knoll]

I prefer player.getPlayer().getPlayer().getPlayer().getPlayer().getPlayer().getPlayer()

[wet breach]

But i think you were surprised you could double cast?

[lost matrix]

What does that even mean??
You guys are trolls

[eternal night]

pfft, I like block.getLocation().getBlock()

[round finch]

🧌 xD

also add many loops

and threads

[wet breach]

Has to do with primitives and objects

[eternal night]

✨ async player getter ✨

[young knoll]

Location.getBlock().getRelative(face).getLocation

[eternal night]

smart

[young knoll]

Smh getRelative in location when

[lost matrix]

Thats a bunch of nonsense. What is your get even doing? Where does that come from?

[eternal night]

everyone is just trolling smh

[round finch]

not me

[wet breach]

But i was using it to demonstrate double casting and what the equivalent was without that

[wet breach]

Comes from Object

[eternal night]

double casting ? xD

[young knoll]

Sometimes you gotta make real sure it got casted

[wet breach]

Did you see my example above?

[eternal night]

you just explained auto unboxing in a shitty way xD

idk what the concept of "double casting" is

like

[young knoll]

SkullMeta skullMeta = (SkullMeta) (SkullMeta) (SkullMeta) (SkullMeta) meta;
