[shadow zinc]

i guess

packets is probably the only feasble way

[wet breach]

using a custom event or couple of them to make generic events is also feasable

[chrome beacon]

Don't detect inventories bu their name

[shadow zinc]

for the purpose of finding the players responsible for the most amount of activity on the server, i guess it could be either or

[rotund ravine]

Just change Cancellable to PlayerEvent

[fervent gale]

then what should I do? to see about matching inventories?

[wet breach]

this would work for the cancellable events, what about the non-cancellable ones?

[chrome beacon]

https://www.spigotmc.org/threads/a-modern-approach-to-inventory-guis.594005/

[rotund ravine]

Change Cancellable to PlayerEvent

I just copied where i listened to cancellable

[fervent gale]

what I'm trying to do is refresh the inventory by checking for title matching and reopening the inv

[chrome beacon]

You want to check the inventory instance

Not the title

[fervent gale]

got an example?

[shadow night]

how do I make an itemstack with the head of a certain player I know the uuid of?

[shadow zinc]

https://tenor.com/view/white-chicks-bathroom-poop-gif-24750810

[rotund ravine]

Make a skull and set the playerprofile @shadow night

[rotund ravine]

?

[shadow night]

hmm

[chrome beacon]

if(currentInventory == inventoryYouWantToDetect)

You probably want a hashmap or simillar though since I assume there will be multiple inventory instances

[fervent gale]

nope just the one

[rotund ravine]

But for multiple people yeahv

?

[fervent gale]

i'm confusing

all i'm trying to do is update the icons if a player joins or leaves or moves to another server
https://i.imgur.com/PEsdCJt.png

[chrome beacon]

Then there is no need to open new inventory

Just modify the item in the inventory

[fervent gale]

😕

[shadow zinc]

so can anyone recommend a library for packets which i can just shade into my plugin? (supporting most versions)

[spiral light]

Is there currently something to get Entities that can spawn in a Biome ?
Or smth to get the mood/cave sounds ? or at least anything from a biome ?

[spiral light]

ProtocolLib i guess

[chrome beacon]

PacketEvents

[chrome beacon]

Can't shade that

[spiral light]

ah ok

[shadow zinc]

one does not shade protocollib into your plugin

i wish i could tho

[shadow zinc]

are you referring to this? https://github.com/retrooper/packetevents

[chrome beacon]

Yes

[shadow zinc]

uhh and if my plugin goes above the size allowed by spigot, what do developers commonly use to host their plugins?

cuz if its 2.5 and my plugin is 2.6, we are going to have a problem

[chrome beacon]

Minimize

[shadow zinc]

I am minimizing

[chrome beacon]

Worst case proguard strip

[shadow zinc]

yeah its 5.1mb

w minimize

i think its minimizing at least

[spiral light]

what is your plugin doing ?

[shadow zinc]

its using mini messages

which is ironically the biggest fucking library i've even seen

[dire marsh]

can't you use libraries feature

[hazy parrot]

you can always do something like this https://www.spigotmc.org/wiki/plugin-yml/ (scroll down to libraries)

[hazy parrot]

you called it

[dire marsh]

(waiting for "im using 1.8")

[shadow zinc]

im using 1.8

https://tenor.com/view/gigachad-chad-gif-20773266

[dire marsh]

kek

[hazy parrot]

you can easly replicate that behavior anyway

[shadow zinc]

doesn't spigot have rules on accessing the internet in a plugin?

or is that just for premium plugins?

also what is spigots plugin upload size?

i figured out i wasn't using minimize and it from 5.1 to 3.1

[hazy parrot]

its just premium afaik

[chrome beacon]

Around 4

[shadow zinc]

sweet

so we up

thanks nerds (respectfully)

is us calling each other nerds like how people of certain races uses race specific slurs?

[spiral light]

i guess noone knows and its not existing

[dire marsh]

biome api has been severely underdeveloped

[spiral light]

yeah i am searching for a way to include datapack biomes more ... but currently all biomes are in an enum and there is no fancy way to change this ....

[clever lantern]

can i disable honey and slime blocks so they are not sticking other blocks to them?

[near mason]

Block#getVoxelShape()#overlaps(BoundingBox) doesnt work properly

[slate tinsel]

If the player is in the air when it leaves, I teleport it back to the ground where it started, but why does the player take damage when it rejoins, how can I solve it?

[young knoll]

Set fall distance to 0

[slate tinsel]

before I teleport?

[slate tinsel]

I'm currently running like this and experiencing the same problem:

• fall distance 0
• Teleport back

[eternal oxide]

set Velocity

[slate tinsel]

player.setVelocity(new Vector(0,0,0));?

[eternal oxide]

yes, after teleport

[slate tinsel]

okey

[echo basalt]

ow static abuse

I need to add some more basics

[slate tinsel]

sorry just used it when testing 😔

have changed now 🙂

[echo basalt]

Also using player keys

[slate tinsel]

Okey, I'll change that too, Thanks for the great feedback 🙂

[storm crystal]

did you really expect people to only come here after they spent 200hrs into java

lol

[near mason]

im using lombok but cant make the builder public ?

[chrome beacon]

No not really

[echo basalt]

Projectile.builder().whatever

[chrome beacon]

also 200hrs of Java isn't that much

[near mason]

ok its fixed ty

[storm crystal]

if you dont have much respect for ur time then maybe

[chrome beacon]

You seem to have the wrong mind set

You only want things done nothing else

You don't seem to want to learn things properly

If that's the case just hire someone to make the plugin

That would be respecting your time better :p

[slate tinsel]

I do this now, same problem though

• player.setFallDistance(0);
• player.teleport
• player.setVelocity(new Vector(0,0,0));

[eternal oxide]

is your location correct?

[echo basalt]

Homie you're not him

[slate tinsel]

yes

[echo basalt]

Programming is like a skill

It may take 10k hours to master yet you still learn something every day

[torn shuttle]

@echo basalt how good are you with quaternions

[echo basalt]

ask 7smile

[eternal oxide]

I can only assume that due to it being in the quit event some settings are not being applied to the player in the event

[storm crystal]

Im not a corporation that can afford it, those people price themselves for much more than they are worth

[torn shuttle]

@lost matrix I need quaternion jesus, I just can't figure this shit out

?paste

[undone axle]

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

[chrome beacon]

No not really. Minecraft devs are usually a lot cheaper than they should be

[echo basalt]

So you're telling me that after spending 12 years of my life learning how to code, and about 7 making plugins in specific, I'm worth less than a guy flipping burgers at mcdonald's

[torn shuttle]

https://paste.md-5.net/ofukupojox.java can someone sanity check my quaternion math because it is not outputting correct rotations

[echo basalt]

Because if that's the case then it's clearly better to just flip burgers yourself and pay a dev

[storm crystal]

without you I wouldnt have video game plugin made, without him I wouldnt have my food, I think that's self-explanatory

[torn shuttle]

I mean....

I didn't say it but you did and I'm happy you did

[lost matrix]

Im about to head out soon ^^
Whats the issue?

[torn shuttle]

everything is correct up to the method that runs on line 76

that is meant to use an anchor point, get a rotation with euler values and create a quaternion which will then rotate the point according to the euler values

[echo basalt]

Your food lasts for 15 minutes, the entertainment value of my plugin lasts for hours or weeks

[storm crystal]

blud forgor about digestion

[echo basalt]

blud forgor about the entertainment industry

[slate tinsel]

Do you have any idea how I can solve this?

[storm crystal]

entertainment aint required to live so yeah I'd still put Burger flipping Joe a bit higher

[lost matrix]

To rotate around a anchor point you need to apply a translation dx, then your rotation, and a translation -dx
where dx is the offset from your current anchor. No idea how to do this using spigots weird methods so i would
apply those directly to the transformation matrix.

[echo basalt]

you don't need your 15$ mickey d's to live either

[eternal oxide]

set the velocity/location on join not on quit

[echo basalt]

The main thing I'm seeing is that you don't take the minecraft industry seriously even though it feeds the mouths of many people, mostly in underpriviledged countries such as india, turkey and brazil

And introduces a lot of teens and such to the programming industry where they may step up to a real job

[storm crystal]

idk why you chose working at fast food restaurnt as some kind of lowest point, those people deal with shitty customers, work tirelessly doing same tasks for hours just to meet loose ends in a lot of cases, so yeah I'd give them that and put them defo higher than plugin devs lol

[torn shuttle]

I mean that's sort of waht I'm trying to do here, no? I've got my anchor, a point, I convert the rotation to a quaternion, I apply the rotation to the vector that is defined between the anchor and the original target and then I get the vector between the original target and the rotated target so I can move my display by the correct amount

[lost matrix]

let me take a look at the code brb

[torn shuttle]

I'm getting a very mixed output which is just bizarre

like

[echo basalt]

We also get to deal with shitty people, experience burnout a lot more often and are undervalued by people like you because all you care about is a burger rather than the talent of a developer

[torn shuttle]

hard to take a screenshot of it but in this test model it's almost completely correct, the only real issue is that the middle cube for some reason is not getting translated around correctly, in the debug data points it's moving by absolutely minuscule amounts that are not possible to see in-game and are just not right

[storm crystal]

digital fun colourful stuff and letters < food my guy, you gotta set the priorities straight, also just because I put you lower than burger flipping Joe doesnt mean that I find both of you bad, altho you arent the best example lol

[torn shuttle]

but shockingly the child of that bone is correct which doesn't make any sense to me

like it's inheriting the same translation and applying it correctly

when the parent doesn't

[echo basalt]

whatever this fight isn't worth fighting

[torn shuttle]

also the values getting passed to it are legit, I check and they seem to make complete sense and it sort of worked with euler rotations (but those are problematic for many well-known reasons)

[storm crystal]

how much do people take for plugins either way

[torn shuttle]

I don't even know how you got baited into such a stupid discussion

[echo basalt]

really good devs maybe 30/hr

most just charge 10-15$/hr

[brazen badge]

I am doing a time command, do you think the best option would be to save the time in the database and then check it or use a runTaskLater?

[echo basalt]

but sure we'll take your criticism and switch to a better paying job at the nike sweatshop

[storm crystal]

hourly???

why?

[echo basalt]

Because it takes effort

[torn shuttle]

I've charged way more than $30/hr

like, way more

[storm crystal]

XD

[echo basalt]

Sure you can make a lot more with commissions and stuff

long-term, these are the rates

[young knoll]

Alex did commissions for €120/h

[storm crystal]

that gives you no guarantee that they wont slack off with job just to squeeze more money

[echo basalt]

I've also made 600$/hr with commissions

[echo basalt]

minimum wage employees do this all the time

[torn shuttle]

yep

[echo basalt]

except we don't get benefits

only paypal fees

[storm crystal]

if they get caught slacking off they're out

[echo basalt]

so are we

[torn shuttle]

usually the trick with me is that I charge a lot hourly but then I'm maintaining systems for years so I think it's fair

[storm crystal]

I assume you are like freelancer

[echo basalt]

somewhat

freelancer / contract worker

[storm crystal]

aint no way company would pay you 120usd/hr

[echo basalt]

What if you're a big youtuber and that person is making all the content on your vids

[torn shuttle]

yeah because companies can and do pay way more than that

[echo basalt]

so you spend 2k to develop a video and it makes 10k

do that every day and you're set

Are you really going to kill your entire company because you want to underpay ppl

[storm crystal]

companies underpay people and it works

[echo basalt]

That's because people can't fight back

We're independent contractors, remember

[lost matrix]

Does getArmorStandOffsetFromModel properly clone vectors internally?

[echo basalt]

We can just switch projects

[storm crystal]

and you can slack off without any pressure from your boss

[echo basalt]

We're not disposable

[storm crystal]

thats like 0 trust

[echo basalt]

homie if you have trust issues that's on you

[torn shuttle]

yes, it's cloned and recalculated through that method

[storm crystal]

giving a random guy 120 usd as hourly wage to have a project done, I wonder if he's gonna actually work efficiently during this hour

https://cdn.discordapp.com/emojis/1100415648665980998.webp?size=48&name=Clueless&quality=lossless

[echo basalt]

random is stretching it by a lot

If the project takes 5 hours to be made, which is 600$

[lost matrix]

Because miniscule changes sounds to me like it gets rotated, and then rotated back, with floating point
precision resulting in a tiny loss.

[storm crystal]

not at all

[echo basalt]

And you get a lot more than 600$ worth out of it

It's worth it

Higher wage = ideally better quality service

[torn shuttle]

I don't mean it's missing a bit of the rotation I mean that the amount of the translation is so small it's in scientific notation

it does not budge

[echo basalt]

So that you don't end up with the "what the fuck" moment when you want to update the project and it needs to be rewritten due to how bad it is

[storm crystal]

it feels like the NFT talk - "trust me you'll profit out of it I assure you"

[torn shuttle]

it should never look like this

[storm crystal]

sus?

[echo basalt]

I'm not telling you that you'll profit out of it, I'm telling you that you get your money's worth

[torn shuttle]

see where the red should be vs where it is?

[chrome beacon]

You can't rotate that freely I believe

[torn shuttle]

you can

[chrome beacon]

hm?

[storm crystal]

theres no guarantee that ill get hour of efficient work with paying for an hour of work

[chrome beacon]

I thought it was a bit limited

[storm crystal]

no guarantee that ill get any work at all

[torn shuttle]

it isn't

not for animations

[young knoll]

Minecraft item models can only have rotations in increments of 22.5 degrees

[echo basalt]

Ah, the typical upfront payment issue

[torn shuttle]

again, not for animations

[echo basalt]

if you pay upfront the guy can scam you

if you don't then you can scam the guy

[young knoll]

half and half

[echo basalt]

but then you can scam the guy out of half his money

you can get a third-party but then the third-party is liable to scamming either of you

[young knoll]

And he can scam you outta half your money

[torn shuttle]

it's called living in a society, deal with it

[storm crystal]

I either sign a legal contract that allows me to sue with ease or I dont get the deal done

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

[echo basalt]

but then you're signing a legal contract over a 15$ plugin ¯_(ツ)_/¯

All I'm getting out of this is that you have mad trust issues

[young knoll]

I mean if you get scammed outa $7.5

[lost matrix]

Yeah, so if you do two calculations, one towards your target, and then the antipodal to it,
the result might look like a tiny movement, just through floating point precision loss.
And i mean tiny as in smallest possible loss.

[remote swallow]

alex got people paying it

[young knoll]

Then idk skill issue

[storm crystal]

you want to say that 15usd has no value?

[echo basalt]

It's worth a burger

[young knoll]

A few boorger

[storm crystal]

its worth a really good burger here

[echo basalt]

nah just one at mickey d's

[storm crystal]

you know

[echo basalt]

Not much more than that

[torn shuttle]

but it should be moving by almost an entire block's span here

[storm crystal]

world isnt just america

lmao

[torn shuttle]

and everything else seems to be working fine

[echo basalt]

I wouldn't sign a contract over 15$ because it takes longer to read the terms than it does for me to get the job done

[echo basalt]

bold of you to assume I live in america

[torn shuttle]

also this issue does not happen when I'm using euler angle rotations

just these quaternions

[echo basalt]

I live in an european country where the wage is around 4$/hr

[storm crystal]

your mindset would fit in here

[echo basalt]

It's just that I value my time and skill

[storm crystal]

https://cdn.discordapp.com/emojis/1086061238338977852.webp?size=48&name=tf&quality=lossless

[torn shuttle]

I think we're up to 4.50

[echo basalt]

If I were to switch to an actual software consulting company I'd charge double

[storm crystal]

but then you wouldnt be able to slack off huh

makes sense why you didnt take it

[lost matrix]

What are your debug values?

[echo basalt]

45 hours per week

760 a month

It's about 4.22

[torn shuttle]

E-17

[echo basalt]

I don't slack off

[wanton falcon]

hello, does anyone know how to give a block with a "can be place on" tag in Minecraft 1.20, using spigot and not command blocks? I've tried, but can't figure out how exactly placeablesKeys are working

[storm crystal]

I have no guarantee over that

https://cdn.discordapp.com/emojis/897425463037816903.webp?size=48&name=pepeshrug&quality=lossless

[echo basalt]

I have no guarantee that you'd pay me in the first place

¯_(ツ)_/¯

[torn shuttle]

it's going up though iirc

I think we're hitting 780 in jan or something

[young knoll]

Sadly we don't have api for that

[minor junco]

@echo basalt this is the longest argument ever on a discord channel about developing questions

[echo basalt]

those extra 20€ can wipe my tears after I look at the housing prices

[torn shuttle]

lmao this guy thinks he's buying a house on minimum wage

you might as well just spend it all in lottery tickets

[echo basalt]

rent is over minimum wage

¯_(ツ)_/¯

[young knoll]

Popcorn is always provided

[minor junco]

Yeah I tried to find the beginning but it's never stopping when I scroll up

[wanton falcon]

k thanks anyway !

[young knoll]

stonks

[storm crystal]

so then how are you 12y skill programmer and still on min wage?

[echo basalt]

because I'm not on minimum wage

I charge 5-6x my country's minimum wage

[storm crystal]

sounded like you are

[torn shuttle]

he's not on minimum wage he's dodging taxes

isn't that right illusion

[echo basalt]

shut up he might be a fed

[torn shuttle]

yeah bud

go legit you parasite

[storm crystal]

if you want to dodge taxes at least give up all things that were funded from them

[echo basalt]

bold of you to assume I dodge taxes lmao

[fallow violet]

what happening here 💀

[torn shuttle]

yeah I would've had to assume if you didn't say you were going to do it after I explained how to go legit months ago

[echo basalt]

exactly months ago

enough time to go legit

[chrome beacon]

Average Spigotmc stuff

[torn shuttle]

there's no shot you're declaring all your revenue, don't try to pull a trick

[storm crystal]

in case of any legal investigation I assure you that I pay my taxes (which are 0 right now)

https://cdn.discordapp.com/emojis/1100415648665980998.webp?size=48&name=Clueless&quality=lossless

[torn shuttle]

@lost matrix any ideas?

[lost matrix]

What is the length of your fromParentToChild vector?

[lost matrix]

Im still trying to figure out the relations between the vectors.

[young knoll]

They are just really good friends

[torn shuttle]

not huge but certainly enough that it should be noticeable

[lost matrix]

I dont get how you could talk like that then, without cringing at yourself...

[echo basalt]

yeah I've been cringing hard all this time

[storm crystal]

I dont have to pay taxes for 6 or 7 more years thats how it is here

so its all legal

https://cdn.discordapp.com/emojis/1086061238338977852.webp?size=48&name=tf&quality=lossless

[echo basalt]

pov: you're 12

[lost matrix]

This means rotatedVector and fromParentToChild are pretty much identical...

[minor junco]

Can someone break down what this argument is about it's quite funny

[echo basalt]

homie basically said we should be paid less because minecraft plugins are basically worthless

[torn shuttle]

actually yes

erm

[echo basalt]

I argued we, as developers, should be paid enough for our work

[minor junco]

Hahaha what an L take

[echo basalt]

Homie said that he'd rather pay 15$ for a burger than 15$ for a dev to work for an hour

and now we're here

[chrome beacon]

Dusk says he values time but wastes our time and their own over trust issues and refuses to pay people to make the plugin for him

[minor junco]

Minecraft plugins or not, depending on the goal it is still programming lmao. I hate that people think it's less work to build complex plugins compared to building other types of similar applications

[lost matrix]

Are you... storing angles inside a vector?

[storm crystal]

I never said that I value my own time, dont put words in my mouth like that

[echo basalt]

read carefully, the word own was never used

don't put words in his mouth like that

and stop going defensive now that we're ganging up on you

sounds like you're losing the argument fr

[storm crystal]

I literally just said that I dont value my own time by that and you are still being picky about it

damn

[echo basalt]

that we can agree on

you don't value your own time

[slate tinsel]

Maybe it works, but then I have to write all the data for the players whether they are to be teleported back or not to a file when the server closes, haven't come up with a better solution myself though.

[echo basalt]

you're here arguing with us

[storm crystal]

and yeah Id rather pay 15usd for a borgar

[torn shuttle]

yes, they represent euler rotation values

[minor junco]

For example I am currently building a powerful anticheat solution since I have an experienced background. I put in so much time and effort into further studying the source of Minecraft and having been programming for 10 years in java now is that less worth than someone with equal amount of experience building a WebApp??

[echo basalt]

For most people spending money on a plugin developer is basically just investing in their server / brand

[torn shuttle]

well at least that was the idea

[storm crystal]

idk why you'd assume that I want to make my server

[echo basalt]

A youtuber is fine paying me 100$/hour if it means they make 150

[lost matrix]

@storm crystal @echo basalt Please move this convo to #verified or #general.

[echo basalt]

tbh I'm fine with calling it quits and going to get lunch

[storm crystal]

nah the cutest discord plugin

[minor junco]

I'm out of this convo now haha I think that dusk is completely in the wrong (if what Illusion said is actually what he meant). Enough with this argument in this channel tho 😆

[torn shuttle]

is there a problem inherent to trying to store those vectors euler angles and converting them to a quaternion representation?

[lost matrix]

Setting the PDC of a player should work fine, right?

[lost matrix]

Storing angles in a positional vector is just a bit confusing to me.
Technically its not a problem.

[torn shuttle]

ultimately the raw data is in x y z coords so it was an attempt to pass and increment it easily

[young knoll]

I pass rotations around in a vector in degree form

Easier for users

[minor junco]

I mean it's similar to how Vector is also a resizable array (java.util) or std::vector in C++ comes down to terminology and usability

[torn shuttle]

I could pass the EulerAngle object instead but you can't do operations on it without having to instantiate a new object

at least not via api methods

so yeah it makes sense to me at least insofar as this problem is concerned that the rotatedvector and fromparenttochild are basically identical because this bone is not budging one bit

so yeah it is basically staying in the same spot

[storm crystal]

how do I structurize SQLite classes

[torn shuttle]

the rotatedVector is wrong

[storm crystal]

like what classes do I need

and what do I use them for

do I just make 1 instance in main

or make it static and call it a day

[torn shuttle]

which really is the whole issue, something about this rotation doesn't make sense to me

it has to be the rotationQuaternion that is incorrect, right?

either that or the rotation method

[lost matrix]

Switch the order of parentupdate and own update

[torn shuttle]

erm

where?

like

[lost matrix]

transform

[torn shuttle]

you want the parent to update after the child?

[lost matrix]

Hm

[torn shuttle]

that can't possibly work right

the data flows downstream not upstream

[lost matrix]

Just let me know how it affects the movement pls

[torn shuttle]

so you want me to do what exactly

because it's depending on the parent's data to rotate

and translate

[torn shuttle]

any specific line you want me to change because I don't realy understand what you want

[lost matrix]

Still thinking how to resilve the conditional update passing

[near mason]

how to get the length of a vector?

[lost matrix]

vector.length()

[upper hazel]

?paste

[undone axle]

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

[torn shuttle]

if it helps you I can stream what it looks like in movement if that helps you visualize it

[lost matrix]

Yeah would be helpful

[upper hazel]

Why does the compiler think that after comparing objects using this, subsequent objects can be null - https://paste.md-5.net/vojugebaha.cs

1. idk what you mean

Hamit

[near mason]

yes?

[rotund ravine]

Please post them in one message lol

Oh u did

[desert marten]

Have you even checked your console for any errors?

[near mason]

its all

[shadow night]

I thought maybe pickaxe needed to break or how long it takes to break

[rotund pond]

First, if you create a get instance property, don't put the instance public.
Then, it's my opinion, but I think using getInstance methods is a bad pattern in this case

[upper hazel]

yes this true

[hazy parrot]

why would it be

[near mason]

there is no error except the one i throw

[hazy parrot]

class that extends JavaPlugin is strictly singleton

[desert marten]

Okay but passing around managers, suppliers, etc. instead of the whole plugin is better.

[shadow night]

What is better for getInstance, saving the instance of the plugin in a constructor or the way where you request the instance from bukkit or whatever

[hazy parrot]

i would personally use Bukkit.getPlugin(clazz)

[shadow night]

Any difference tho? Besides preference

[rotund ravine]

DI is our most beloved

[hazy parrot]

just use spring ioc smh

[hazy parrot]

idk tbh

[shadow night]

Why do peoplo nowadays like lombok so much

I personally don't like how it looks

[rotund ravine]

Cause it’s easy

I just use kotlin 💪🏻

[shadow night]

Lol

How to be a hated member in spigotmc

[rotund pond]

Your whole plugin will be tight coupled (I don't think it's the right term, it's a literal translation from a french term) with your main class.
To me, all classes have to loose coupling by using dependency injection for example

By the way, using a getInstance method can encourage practices that can make the code less maintainable and less testable. For example, since the main instance is easily obtainable, there may be a temptation to "stock" all plugin dependencies into this class, even though it's not its responsibility.

[desert marten]

Pass around managers and suppliers

[hazy parrot]

and less testable
this is indeed true

[desert marten]

@Getter
@Setter

So good

[rotund pond]

As I said, it is only my opinion, I don't have time to talk about it

[desert marten]

And @RequiredArgsConstructor

[shadow night]

I hate how that looks

[desert marten]

Your opinion is the most correct

What you described is the principle of oop lol

[desert marten]

You'll start loving it

Sooner or later

[shadow night]

No

[rotund pond]

Yeah I know, but I know that a lot of people don't want to learn what OOP really is, and are lasy
A lot of people prefer doing fast things instead of good things... And in this case, using getInstance everywhere can be a solution. A bad one, but still a faster one.
(Even tho, as Uncle Bob said, "The only way to go fast is to go good")

[near mason]

any ideas why it doesnt work?

[upper hazel]

why the strength of the block and its resistance are protected and private; why is this needed? Nonsense

[desert marten]

fr

[hazy parrot]

I don't think if something can encurage bad practices is indeed bad

[upper hazel]

i mean you not can change this

[hazy parrot]

in that case static shouldn't be used, as it can encurage bad practice

[upper hazel]

if not use nms

[rotund pond]

Fair enough

[near mason]

ok guys i fixed it np

it was bec if (!alive)r.cancel()

i now remove it on hitevent

[shadow night]

Is the variable actually named r or is it just something your wrote rq

[storm crystal]

what does "this" mean

like this.something

how am I supposed to interpret it

[shadow night]

Isn't that basic java

[hazy parrot]

"reference" to current object

[near mason]

it is

[shadow night]

You are depressing me

[storm crystal]

and whats that object

like what it is

[hazy parrot]

what is object ?

[near mason]

actually it is in lambda

so no problem

[shadow night]

Well

Do whatever ya want

[storm crystal]

um yeah what can be object

is it just class instance

or what

[hazy parrot]

yes, its class instance

[storm crystal]

so why even call it object

[rotund ravine]

Duskkk

Sigh

[rotund pond]

I think you should learn the basis of OOP

[shadow night]

Yes

[sullen wharf]

Yes

[storm crystal]

Great it still doesnt explain why use object name for class instance

Isnt that redundant

[rotund ravine]

An object is a basic unit of object-oriented programming that represents a real-life entity. An object has state, behavior, and identity. State means the data or value of an object, behavior means the functionality or action of an object, and identity means the unique identifier of an object. For example, a car is an object that has state (color, model, speed, etc.), behavior (drive, brake, park, etc.), and identity (license plate number, VIN, etc.).

An object is created from a class, which is a blueprint or template for defining the common properties and methods of a group of objects. A class specifies what an object can do, but not how it does it. An object is an instance or result of a class. For example, a class can be a vehicle, and an object can be a car, a bike, a truck, etc. that belong to the vehicle class.

You can create and use objects in Java by using the keyword new, followed by the class name and the object name. For example, Vehicle car = new Vehicle(); creates an object named car of the class Vehicle. You can access the attributes and methods of an object by using the dot operator (.). For example, car.color = "red"; assigns the value "red" to the color attribute of the car object, and car.drive(); calls the drive() method of the car object.

You can learn more about objects and classes in Java from the following web sources:

[storm crystal]

If its chat gpt im not gonna read it D:

[rotund ravine]

Literally explains it for you

Doesn’t matter where it’s from

[sullen wharf]

Imagine a class instance as a real-life object, obviously it's non-physical

you can do whatever with it, until it stops existing

[storm crystal]

Does

[sullen wharf]

It's called an Object because that what it actually is... its just not physical

[rotund ravine]

A car is both a vehicle and a car, isn’t it redundant to have the word car when there’s already a vehicle word? @storm crystal

[sullen wharf]

Also, it's literally a link for GeeksForGeeks there

what u talking about

[storm crystal]

This assumes there is more than one vehicle

While in objects there is just class instance

[hazy parrot]

What

[sullen wharf]

whattf

[storm crystal]

You told me that

[eternal oxide]

learn inheritance

[hazy parrot]

Idk if dude is high

[sullen wharf]

opium

[storm crystal]

.

"Is it just a class instance" yeah

[hazy parrot]

Class instance is kinda synonim for object

[storm crystal]

You worded it awfully poorly then

[rotund ravine]

@storm crystal It’s basically the same thing, just because there is two words for it does not make it redundant

[storm crystal]

Apparently its not

[hazy parrot]

What, you asked is object class instance and I said "yes it is"

What is poorly worded there

Xd

[rotund ravine]

It is basically the same thing

[storm crystal]

Is an object JUST a class instance

[rotund ravine]

Basically

[hazy parrot]

Tf

[storm crystal]

Implies theres nothing more to it

[rotund ravine]

?

[rotund pond]

Tbf, an object is not exactly a class instance. It is the association of methods and properties using these properties
They can be used in every paradigm

A class is a pattern that an object has to respect. When you instanciate a class, you create an object based on the class.

Using little words, OOP encourages modeling real-world entities, data, and behaviors using this approach. Classes enable encapsulation (grouping data and methods), abstraction (hiding implementation details), inheritance (reusing properties and methods), and polymorphism (treating objects interchangeably), making code more organized and flexible.

I know that this definition is not perfect, and a bit bad when you really know what OOP really is, but it's still a good way to start in my opinion.

Tbf, I really think you should read books and articles for a better understanding. Being a developer is not "coding working things", but "developing working applications which you can iterate easily". OOP is an answer to the problem given in the end of my definition of what a developer really is in my opinion.

Sorry if something is weird, I'm still learning English 🙏

[icy beacon]

Nitpicking onto the naming that has been made years ago does not get you far lol

[storm crystal]

Then why wont people just answer it like that?

[rotund ravine]

He did

You asked if it was the same thing, which it basically is

Then started saying it was redundant

[ivory sleet]

the entire meaning of oop got interpreted wrongly in the very first place, I think it was meant to be a paradigm of sending messages, not modelling and objectifying around behavior and data

[storm crystal]

because it apparently is

why name a thing two different things when its basically the same

[rotund ravine]

Vehicle, car

[hazy parrot]

Literally definition of object is "instance of a class"

[rotund pond]

You have your answer in my message

[hazy parrot]

Idk what is not clear there

[sullen wharf]

It's not two different names

it's the definition of the name

what it means

[storm crystal]

great what other "vehicle" is there other than class instance

[rotund ravine]

There is probably a lot of synonyms in programming

[sullen wharf]

you're fried

[storm crystal]

yeah but

ure not writing a poem

ure programming

[sullen wharf]

it's a form of art

imo

[storm crystal]

xd

so if your code sucks and barely works you might just call it "a form of art" and leave it be?

[sullen wharf]

I mean, art is subjective and to each their own

if you love what you do and you do it with passion you can call it art, I would say

[rotund ravine]

Programming is sort of a poem because both involve using a language to express ideas, emotions, logic, and creativity. Programming languages and poetic languages have their own syntax, semantics, and structures that can be manipulated to produce different effects and meanings. Both programming and poetry can also be seen as forms of art, as they can generate visual, auditory, or interactive outputs that can be appreciated by humans and machines.

Some examples of code poetry are:

• The code {poems} anthology¹, which is a collection of 55 poems written by web developers around the world in various programming languages. The code can speak literature, logic, math, and this code is meant to be read, not run¹.
• The ./code –poetry book², which is a unique collection of poems written in various programming languages’ source code. Each poem is a valid program that produces visual artwork when compiled, and the entire book is formatted and designed to look like a piece of visual art².
• The Source Code Poetry Conference and Challenge, which are annual events that celebrate the intersection of computer science and poetry. The rules of the challenge are simple – poems must compile, must rhyme, and must be cool.

You can find more information and examples of code poetry by searching the web or browsing the links I provided. I hope this helps you understand why programming is sort of a poem. 😊

I do love your way of thinking

[sullen wharf]

boom

[icy beacon]

Sir this is spigot not philosophy 101

[sullen wharf]

🙏

[storm crystal]

isnt that excuse to poor quality code

like machine is supposed to read it

[rotund ravine]

Lol

[storm crystal]

I dont think that it'd care if you used 50 different forms of words or just one word

[icy beacon]

What point are you trying to make

I'm confused

[sullen wharf]

Sure, it also can be an excuse for bad paitings FOR U, but for the person that made it not

[rotund ravine]

He’s just trolling

[icy beacon]

I HOPE he is not serious

[storm crystal]

synonyms kinda suck in programming

[icy beacon]

Don't use them

Problem solved 🔥

[sullen wharf]

🔥

[storm crystal]

it really is not

[icy beacon]

Yeah it is

Gg

[rotund ravine]

Imagine when he learns anonymous inner classes are also objects

[icy beacon]

😮

[storm crystal]

no I still dont get the point of using both object and class instance names at the same time

[icy beacon]

Then don't do it. Boom you don't have to look for the point

[sullen wharf]

Programming is also about developing your style while using common designs and patterns, if you don't like something simply don't do it

there's always another way to make the same thing

[storm crystal]

so u've been basically gatekeeping actual answer?

[rotund ravine]

Copilot 😝 No more work for me

[storm crystal]

cool

[rotund ravine]

Gatekeeping?

Lol

[icy beacon]

do you know what the fuck gatekeeping is 👍

[sullen wharf]

If you don't fancy naming stuff one way then don't it, 😮

[hazy parrot]

Object is class instance. That is definition of the object

[storm crystal]

yeah but isnt programming about efficiency rather than expression

[icy beacon]

ALright ask the very question one more time I'll try to see if your words make sense

[hazy parrot]

Same as you would say spoon is metal shit which u use to pick up soup

[storm crystal]

like you want to get your job done nice and well not make the code look flashy

[rotund ravine]

Efficiency does not contradict expression

[hazy parrot]

Yes u still call it spoon

[sullen wharf]

Sure, but that's a whole other point

[storm crystal]

but why need another name for something that is already short

[icy beacon]

Ok he joined 2 days ago, bro's DEFINITELY not looking for the answer, you were right jantuck I'm leaving the convo xD

[storm crystal]

if you dont need anything else with it

[hazy parrot]

Yeah he is troll

[sullen wharf]

what other name my g

[ivory sleet]

I mean, u use both addition and multiplication, even tho multiplication is just addition many times

[rotund ravine]

He’s been here for more than 2 days i think?

[storm crystal]

I didnt join 2 days ago

[icy beacon]

Wait nvm I'm blind

32 days

[sullen wharf]

A class instance is the "definition" of what an Object is

what is difficult to understand there

wtf

[chrome beacon]

Just ignore them it's a waste of time

[storm crystal]

why not cut it short and use class instance word instead of object if object is nothing more special?

[hazy parrot]

Wait till he realise there is Object class

[sullen wharf]

OOP -> Object Oriented Programming

[storm crystal]

what advantage does it give?

[hazy parrot]

Gonna blow his mind for sure

[sullen wharf]

it's not CLASS INSTANCE ORIENTED PROGRAMMING

[rotund ravine]

Object is shorter and oritentef towards the design of object oritented programmind

[storm crystal]

great but object definition must've been made before the name

[icy beacon]

I don't know how to tell you that no one here is in charge of creating the namings

[sullen wharf]

go to sleep

i'm out

[icy beacon]

So if you are dissatisfied with them

It's kinda your problem

[icy beacon]

Same

[storm crystal]

not forcing you

[storm crystal]

im literally just asking why is that a thing

[rotund ravine]

And then doubting us when we tell u the answer

[storm crystal]

great OOP has Object in it but that doesnt explain why Object is Class Instance, the name clearly's been made after Object's definition's been established

[rotund ravine]

What name

[sullen wharf]

https://en.wikipedia.org/wiki/Object_(computer_science)

read that whole page

[storm crystal]

OOP name

[sullen wharf]

and be happy

[rotund ravine]

Oop was made way before java

[storm crystal]

so what did people have in mind when saying "let's call class instances objects"

[sullen wharf]

there's everything you need here

👍

[storm crystal]

what advantage does it give

[rotund ravine]

.

[storm crystal]

u're already tilted for some particular reason so I dont trust you anymore lol

[sullen wharf]

if you read carefully, it's not just a class instance, there's more to it. That's a simplified version of what it is

[echo basalt]

because there's isnt much work

[rotund ravine]

Woah, why is it called operator then? Isn’t that redundant?

Jkjk

[sullen wharf]

but I like to have some work outside of home

[storm crystal]

so do I dump all methods for SQLite in one class or make separate classes for it

like class for creating db

etc.

[echo basalt]

shoot for the stars aim for the moon

[sullen wharf]

You ain't cool, 'til I say you cool

[echo basalt]

the way I do my sqlite is by basically just having this huge abstraction

that does literally nothing

other than making stuff configurable

[storm crystal]

helpful

[shadow night]

is there some way to run a minecraft server from idea

[sullen wharf]

idk the correct term in english

in here it's operator

so whatever

[storm crystal]

whats the point of making something that does nothing

[echo basalt]

so then I make an interface for whatever storage

make a class that extends my abstract sqlite class and impls the interface

[storm crystal]

okay but

I asked

do I dump it to one class

[echo basalt]

and do logic

[storm crystal]

or make separate classes

for getting data making database removing data reading data

[echo basalt]

I'd say make one class per data type

So if you're storing player data and item data

You have a player data "DAO" and an item data "DAO"

[storm crystal]

[rotund ravine]

That’s a pessimistic approach

[storm crystal]

which you are talking about

[rotund ravine]

You should view life in a more optimistic way

Instead of “it implies it will fail” you should view it as “it implies it might work”

[storm crystal]

"try and see" from both you or that other guy towards me is no other than "go and waste ur time and come back with not working code cuz itll 100% wont work"

[echo basalt]

I'm so glad he's attempting to learn java

[storm crystal]

beloved w3schools doesnt explain it at all

[echo basalt]

he can finally start valuing all the other developers around him

[remote swallow]

get the car vehicle and bike thing out

[storm crystal]

like great you can do that

but why not just make those methods in a class

instead of implementing interface

[cedar marlin]

How do I send screenshots?

[storm crystal]

they state "1) To achieve security - hide certain details and only show the important details of an object (interface).", but what would you be actually hiding

[remote swallow]

a car and a bike are both vehicles, you want a method to take both

[storm crystal]

and from whom

[remote swallow]

you dont take two params that are nullable

you take a vehicle

[echo basalt]

Depend on abstractions, not concrete implementations

[storm crystal]

what does nullable mean

[remote swallow]

null-able

its self explanatory

[echo basalt]

Habit 7e

[storm crystal]

then why wont you specify what you are taking in method and call it a day?

[echo basalt]

Dependency Inversion

[remote swallow]

because its an interface

[rotund ravine]

An interface in Java is a way to define a set of common behaviors that different classes can implement. By using interfaces, you can achieve abstraction, polymorphism, and multiple inheritance in Java. Let me explain these concepts briefly:

• Abstraction means hiding the implementation details and only showing the essential features of an object. An interface is a completely abstract class that only contains abstract methods and constants. When a class implements an interface, it promises to provide concrete implementations for all the abstract methods. This way, you can program at the interface level, instead of the specific implementation level. For example, you can use the interface Animal to define the common behaviors of animals, such as animalSound() and sleep(), and then have different classes, such as Pig, Dog, and Cat, implement the interface and provide their own versions of these methods. You can then create an array of Animal objects and call the interface methods on each element, without knowing the exact type of each animal¹²³.

• Polymorphism means the ability to perform the same operation on different types of objects. An interface is a way to achieve polymorphism in Java, because you can use the same interface reference to point to different objects that implement the interface. For example, you can use the interface FirstInterface to define a method myMethod(), and then have different classes, such as DemoClass, AnotherClass, and ThirdClass, implement the interface and provide their own implementations of myMethod(). You can then create a variable of type FirstInterface and assign it to any object that implements the interface, and call myMethod() on it, without knowing the exact type of the object¹².

• Multiple inheritance means the ability to inherit from more than one superclass. Java does not support multiple inheritance for classes, because it can cause conflicts and ambiguity. However, Java supports multiple inheritance for interfaces, because interfaces only contain abstract methods and constants, and do not have any implementation details. Therefore, a class can implement more than one interface, and inherit the behaviors from all the interfaces. For example, you can use the interfaces FirstInterface and SecondInterface to define different methods, such as myMethod() and myOtherMethod(), and then have a class, such as DemoClass, implement both interfaces and provide implementations for both methods. You can then create an object of type DemoClass and use it as either a FirstInterface or a SecondInterface reference, and call the methods from both interfaces on it¹².

[storm crystal]

doesnt tell me anything

[echo basalt]

An interface is a contract that describes what methods an implementing class has, so if you say you're an animal, you must surely have a breathe method or something

And you can pass a generic Animal and make it breathe

[storm crystal]

you know that you can just post a link if you want to scrap things out of the internet

[echo basalt]

do your own research for anything else I'm not helping ppl who don't appreciate developers charging a fair price for their knowledge

https://www.javatpoint.com/interface-in-java

[rotund ravine]

But you won’t read our links

[echo basalt]

go watch that bald dude's yt vids

[storm crystal]

at least have some respect for people who wrote those articles and cite them

[echo basalt]

I'm seriously considering just blocking this troll

jan, opinions?

[storm crystal]

thanks

[rotund ravine]

I did

But he still showed up cause phone

[echo basalt]

my turn

done

[storm crystal]

I still dont get the difference

making method1 and method2 in class

or making interace with those methods and implementing it into the class

I still need to fill it

with code

[rotund ravine]

We’re not ur teachers or your parents. Go pay someone to hold ur hand

[storm crystal]

nobody's forcing you to help, or brag about how you are not gonna help

[eternal oxide]

a car has an engine but a bicycle doesn;t. if you return a simple Vehicle Object a bicycle would have an engine method.

[rotund ravine]

But, the human is the engine.

[eternal oxide]

lol

you not helping 🙂

[rotund ravine]

I know

Everything u said were explained in the links i posted

[storm crystal]

okay but where does interface work here

[eternal oxide]

you retun the interface when getting a car or bicycle, not the Vehicle

[storm crystal]

cant i make separate class for bike and not make engine in here

[eternal oxide]

yes you could

[storm crystal]

isnt interace supposed to be empty

[eternal oxide]

yes

[storm crystal]

like consisting of only blank methods

[rotund ravine]

@drifting halo You want a go?

[storm crystal]

so I return

blank methods

[sullen wharf]

Interface Vehicle contains a brake method, both car and bike will implement Vehicle and have that method that is common in both

[storm crystal]

what happens then

[sullen wharf]

Wdym

[storm crystal]

what happens after I return interface

[pseudo hazel]

nothing

its very hard to understand what you are confused about

[sullen wharf]

Ye

[rotund ravine]

So. The blank methods specify conditions or methods things have in common, but doesn’t implement the same. So Vehicle ss Lukas has said has a brake method.

Bike breaks differently than Car.

But to your code you just do

some method takes vehicle

Vehicle vehicle = this.vehicleManager.getVehicle(uuid);
vehicle.brake();

[sullen wharf]

Yay

[rotund ravine]

An interface does nothing by itself

[sullen wharf]

And he will find a way to not understand that

🤨

[storm crystal]

why make this (the first) when I can do this (second)

thats what im confused about

[remote swallow]

because you could have 900 animals

[sullen wharf]

Because you're missing out on abstraction and scalability

[remote swallow]

you dont want to make a method have 900 params

[sullen wharf]

Also, it's not right

As most animals have stuff in common

So why not?

[echo basalt]

He's asking like

Why would I have Animal pig = new Pig()

Rather than just using Pig directly

[sullen wharf]

Oh

[echo basalt]

My response is

[sullen wharf]

Depends on context

[echo basalt]

Let's say you have 20 animals

[storm crystal]

no im not asking about it

[echo basalt]

Are you really going to store 20 lists

[storm crystal]

lol

[glad prawn]

Pig is Animal and is Object

[echo basalt]

Or are you just going to have a List<Animal> barn

[rotund ravine]

https://stackify.com/solid-design-liskov-substitution-principle/

[echo basalt]

Not really liskov more like DI

[eternal oxide]

Animal would be abstract so it can;t be instanced

[echo basalt]

Liskov basically means you can't unimplement methods through inheritance

[storm crystal]

I get definition of abstraction but I dont get the point

why not allow access to information

[echo basalt]

You have all the information you need through the interface contract

You don't want to expose implementation details because they can change at any time

and regardless of implementation your code should work

[drifting halo]

huh?

[storm crystal]

yeah I dont get it

[storm crystal]

great they change and what now

what if they change

like what happens

[echo basalt]

Your code should still work

[drifting halo]

just learn java dab

[storm crystal]

okay

and then

[echo basalt]

that's all

[storm crystal]

something bad happens?

[echo basalt]

It shouldn't break

and you don't need to know how it works

[storm crystal]

so why I need abstraction and interfaces?

[echo basalt]

the same way you don't need to know what type of collection your objects are stored on, if it's a set or a list who cares

[echo basalt]

Polymorphism

[quaint mantle]

Just learn OOP itself

[pseudo hazel]

you can do whatever, its probably easier to see the actual benefit when you run into issues not using certain things

[echo basalt]

You can for example, make an interface which represents how your data is stored

[storm crystal]

I literally ran but looks like I can go fine without it

[echo basalt]

And have an impl for mongo, for sqlite, for mysql

[pseudo hazel]

then dont use it

[storm crystal]

why would I need it?

[echo basalt]

And interchange between impls yet keep the contract intact

[storm crystal]

but looks like it wont work and nobody wants to tell me why

[echo basalt]

that's a basic real example that you don't care about because you don't need to use anything other than yml

so why am I even bothering

[storm crystal]

you told me to change it to dbs instead of configs

[echo basalt]

I didn't

Here's an example of polymorphism

I have these interfaces and implementations for it

[storm crystal]

what about them

idk what I in circle is

like C is .java file
