Move the spacer above the button?

obtuse gale Feb 19, 2021, 9:52 AM

#

#

How do i move the spacer lol

hot hull Feb 19, 2021, 9:53 AM

#

These are the spacers you need

obtuse gale Feb 19, 2021, 9:53 AM

#

but the spacers get in the way of the components lol

hot hull Feb 19, 2021, 9:53 AM

#

Make the components first, then put in the spacers

obtuse gale Feb 19, 2021, 9:54 AM

#

I havent put one spacer in

#

IJ put it in for me .-.

#

also idk what these lines are

#

#

because they get in the way of components but they arent spacers

hot hull Feb 19, 2021, 9:57 AM

#

Check the xml file idk

obtuse gale Feb 19, 2021, 9:59 AM

#

#

I got it here which is close enough

#

problem when its actually put in it looks shit lol

#

everythings so small

hot hull Feb 19, 2021, 10:00 AM

#

Well yea

#

You need to set the size of the components

obtuse gale Feb 19, 2021, 10:00 AM

#

This is the sized everything is atm lol

old wyvern Feb 19, 2021, 10:01 AM

Group them into multiple layouts

obtuse gale Feb 19, 2021, 10:01 AM

#

what

hot hull Feb 19, 2021, 10:01 AM

#

You're also having them through the entire page which looks hideous

old wyvern Feb 19, 2021, 10:01 AM

#

Youd normally be usign nested layouts to form your ui

obtuse gale Feb 19, 2021, 10:01 AM

#

what lol

#

how

#

idc how its donei just need it to look ok and have 3 JComboBoxes and a JLabel for each

old wyvern Feb 19, 2021, 10:02 AM

#

The top part looks like it could use a row box layout, and for the bottom one a similar vertical one

obtuse gale Feb 19, 2021, 10:03 AM

#

i dont know what those words mean lol whats a row box layout

Can anybody explain me the difference between those different joins?

EQUIJOIN, THETAJOIN and NATURAL JOIN

obtuse gale Feb 19, 2021, 10:31 AM

#

Wait why am i meant to use layouts instead of just chucking it all in again?

Cleanness

unkempt tangle Feb 19, 2021, 10:35 AM

#

Natural Join is the ON clauses on ALL collumns
Theta Join allows you to specify conditions >, <, <>
Equi Join is the most common on it allows you to equal two relations with each other.

#

Is this correct?

But up to you I guess

obtuse gale Feb 19, 2021, 10:50 AM

will that change the appearance of it? Or will it still be way too small

#

#

OR just make this look less shit lol

old wyvern Feb 19, 2021, 10:50 AM

#

It will be easier to maintain spacing possibly

#

You wont have to spam spacers everywhere

#

Also, didnt ij provide its own lib for UIs for plugins?

does it?

ah, IJ's UI

old wyvern Feb 19, 2021, 10:53 AM

So now you'll need to shade that if you need to use it

jovial warren Feb 19, 2021, 10:53 AM

probably because they have their own UI system

I can help him then if you want

obtuse gale Feb 19, 2021, 10:57 AM

If you could help me out in that I would really appreciate it

That would be good actually 😄
What about if you make a working plugin that does that and eventually a simple explanation on how it's done?

jovial warren Feb 19, 2021, 10:59 AM

#

I'd rather just make code that works and then explain that, and then you/your dev can make the plugin themselves

#

tell your dev it will require NMS, he might know what that means

obtuse gale Feb 19, 2021, 11:00 AM

#

That's the idea, the dev does know what nms is and he's good at it but I think it requires a little bit of "extra" knowledge on that

Awesome! Basically we are working on a shooting gamemode which requires to send a packet that replicates the crossbow pulling like in the picture, as simple as that just to clarify 😄

the rule is: if it's something that other players can see, it's a packet that's sent and received

obtuse gale Feb 19, 2021, 11:05 AM

#

So no plugin to prove it, but I saw it was actually doable

obtuse gale Feb 19, 2021, 11:05 AM

#

jovial warren the rule is: if it's something that other players can see, it's a packet that's ...

Ok!

#

For each kind of packet?

jovial warren Feb 19, 2021, 11:06 AM

#

basically, let me try and explain how client-server works in the easiest way possible

obtuse gale Feb 19, 2021, 11:06 AM

#

All right

jovial warren Feb 19, 2021, 11:07 AM

#

when you want to do something, you send something called a "packet" to the server, basically saying "hey, I'm doing this", and the server generally either responds to you and says "okay, I've received that" (called an acknowledgement), and then either another response packet to just you saying "right, I've got all that, now can you do this?"

#

or they will send a packet to other clients saying "hey, x is doing this"

obtuse gale Feb 19, 2021, 11:08 AM

#

jovial warren or they will send a packet to other clients saying "hey, x is doing this"

That one matters in our case?

jovial warren Feb 19, 2021, 11:08 AM

#

indeed

obtuse gale Feb 19, 2021, 11:08 AM

#

🙂

jovial warren Feb 19, 2021, 11:08 AM

#

we need to find the packet where the client goes "hey, I'm drawing my crossbow back" and then the server tells the other clients "hey, x is drawing their crossbow back"

obtuse gale Feb 19, 2021, 11:09 AM

from the backstage someone suggested me that: entity equipment packet

jovial warren Feb 19, 2021, 11:10 AM

obtuse gale Feb 19, 2021, 11:11 AM

#

Good!

jovial warren Feb 19, 2021, 11:11 AM

#

you're right

#

send an entity equipment packet with the entity ID (likely just an NMS entity in our case), the slot as a byte enum (likely just an enum), and some NBT data about the item

somber tulip Feb 19, 2021, 11:12 AM

Protocol

Minecraft Wiki

Player.dat format

<player>.dat files are used by servers to store the state of individual players. The format is also used within level.dat files to store the state of the singleplayer player, which overrides any <player>.dat files with the same name as the singleplayer player. These files are in NBT format.

because SLF4J superior

then it won't compile, since those are all non-null

that's all the code pretty much for the status

java.lang.Character#isUpperCase

public static boolean isUpperCase(char ch)```

Description:

Determines if the specified character is an uppercase character.

A character is uppercase if its general category type, provided by Character.getType(ch), is UPPERCASE_LETTER. or it has contributory property Other_Uppercase as defined by the Unicode Standard.

The following are examples of uppercase characters:

Many other Unicode characters are uppercase too.

Note: This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the isUpperCase(int) method.

Parameters:

ch - the character to be tested.

Returns:

true if the character is uppercase; false otherwise.

jovial warren Feb 19, 2021, 4:10 PM

jovial warren Feb 19, 2021, 4:11 PM

and MineKraft is in Kotlin, not F# lol

also, the lack of consistency in the protocol is so frustrating

I mean ig its ok

because you could add some inner methods and stuff

inside the angle to change it up

and it would be useful

there'll be a method to change it to degrees, and to make a new angle from degrees, since those are a pain

```got a feeling that's gonna be a bit slow

#

anyone here good with optimisation?

lunar cypress Feb 19, 2021, 11:56 PM

#

Well, first of all, you don't have to create the same packet over and over again

jovial warren Feb 19, 2021, 11:57 PM

#

that is a good point

lunar cypress Feb 19, 2021, 11:57 PM

#

Also whatever sessions is (i'm assuming a collection), you don't need to make a new collection with filter there

jovial warren Feb 19, 2021, 11:57 PM

#

what can I do instead?

lunar cypress Feb 19, 2021, 11:58 PM

#

Sequence

jovial warren Feb 19, 2021, 11:58 PM

#

SessionStorage.sessions.asSequence().filter { it != session && it.currentState == PacketState.PLAY }.forEach {
    it.sendPacket(rotationPacket)
}
```so this?

lunar cypress Feb 19, 2021, 11:59 PM

#

Those could already be classified as very small optimisations because the input won't be too big but it may still be beneficial if this is called very often

jovial warren Feb 19, 2021, 11:59 PM

#

it can be called as often as nanoseconds apart

lunar cypress Feb 19, 2021, 11:59 PM

#

Yeah something like that

jovial warren Feb 19, 2021, 11:59 PM

#

sequences vs collections?

#

what's the difference there?

lunar cypress Feb 20, 2021, 12:00 AM

#

If it's really critical you might have to ditch filter completely but that's not a judgement I would make before profiling

jovial warren Feb 20, 2021, 12:00 AM

#

how would you even ditch filter?

lunar cypress Feb 20, 2021, 12:00 AM

#

for each + if statement

lunar cypress Feb 20, 2021, 12:01 AM

#

jovial warren what's the difference there?

filter, when called on a collection, creates a copy of that collection

jovial warren Feb 20, 2021, 12:01 AM

#

whereas called on a sequence, it doesn't, since we already have the instance of the sequence

#

on collection, it's gotta run through all the elements, pick the ones matching the predicate, then create a new collection only containing those elements

lunar cypress Feb 20, 2021, 12:02 AM

#

It still creates a new sequence object

jovial warren Feb 20, 2021, 12:02 AM

#

which I imagine is quite expensive

prisma wave Feb 20, 2021, 12:02 AM

#

Sequences don't create collections

#

Unless you tell them to

jovial warren Feb 20, 2021, 12:02 AM

#

prisma wave Sequences don't create collections

yeah not what I was saying

prisma wave Feb 20, 2021, 12:02 AM

#

O nvm I misread your message

jovial warren Feb 20, 2021, 12:02 AM

#

also, I got some whacky maths going on with positioning

prisma wave Feb 20, 2021, 12:03 AM

#

Don't prematurely optimise

jovial warren Feb 20, 2021, 12:03 AM

#

well I don't want rotation to visibly lag if I can help it lol

prisma wave Feb 20, 2021, 12:03 AM

#

Keeping it as a sequence will probably be good enough

jovial warren Feb 20, 2021, 12:03 AM

#

yeah I'm keeping it as a sequence for now

prisma wave Feb 20, 2021, 12:03 AM

#

jovial warren well I don't want rotation to visibly lag if I can help it lol

Is it lagging?

jovial warren Feb 20, 2021, 12:04 AM

#

also, ```kotlin
val oldLocation = session.player.location
val newLocation = packet.location
session.player.location = newLocation

SessionStorage.sessions.filter { it != session && it.currentState == PacketState.PLAY }.forEach {
it.sendPacket(PacketOutEntityPosition(
session.id,
((newLocation.x * 32 - oldLocation.x * 32) * 128).toInt().toShort(),
((newLocation.y * 32 - oldLocation.y * 32) * 128).toInt().toShort(),
((newLocation.z * 32 - oldLocation.z * 32) * 128).toInt().toShort(),
packet.onGround
))
}

#

got a feeling that doing two separate conversions there is a terrible idea

prisma wave Feb 20, 2021, 12:04 AM

#

You got enough magic numbers there

jovial warren Feb 20, 2021, 12:04 AM

that's an algorithm

#

https://wiki.vg/Protocol#Entity_Position

Protocol

#

change in position as (current * 32 - prev * 32) * 128

forest pecan Feb 20, 2021, 12:06 AM

#

you know, you could use some math and optimize that using bitwise operators

#

lol

lunar cypress Feb 20, 2021, 12:06 AM

#

Just no

forest pecan Feb 20, 2021, 12:06 AM

#

why no 🙂

jovial warren Feb 20, 2021, 12:06 AM

#

are bitwise operations faster than standard pure maths stuff?

forest pecan Feb 20, 2021, 12:06 AM

#

Uh.. yeah

prisma wave Feb 20, 2021, 12:06 AM

#

in some cases

jovial warren Feb 20, 2021, 12:06 AM

#

surely multiplication is about the same as bitwise stuff

forest pecan Feb 20, 2021, 12:06 AM

#

its a bit shift

#

you shift by 5

#

for 32 and shift by 7

#

for 128

jovial warren Feb 20, 2021, 12:07 AM

#

direction?

lunar cypress Feb 20, 2021, 12:07 AM

#

Extract this into a proper function first

prisma wave Feb 20, 2021, 12:07 AM

#

I feel like a compiler could probably optimize constant multiplication into shifting where applicable

#

^^^

forest pecan Feb 20, 2021, 12:07 AM

#

Bro I wish

#

Does java do that?

jovial warren Feb 20, 2021, 12:07 AM

#

right, I'm gonna write this down and do this tomorrow lol

prisma wave Feb 20, 2021, 12:07 AM

#

It might be done in the JIT

#

No idea tho

#

Just an educated guess

forest pecan Feb 20, 2021, 12:08 AM

#

I mean ig it wouldn't hurt

#

to add it

jovial warren Feb 20, 2021, 12:08 AM

#

and when I say write this down, I mean on physical paper with a physical pen xD

prisma wave Feb 20, 2021, 12:08 AM

#

consider using a faster language like Rust

forest pecan Feb 20, 2021, 12:08 AM

#

(current * 32 - prev * 32) * 128 = 32 (current - prev) * 128

#

you could simplify that to a bitwise

lunar cypress Feb 20, 2021, 12:08 AM

#

Only do that if it matches what the calculation is supposed to express, not because it happens to be a power of 2

prisma wave Feb 20, 2021, 12:08 AM

#

forest pecan (current * 32 - prev * 32) * 128 = 32 (current - prev) * 128

Yea I was thinking that

forest pecan Feb 20, 2021, 12:09 AM

#

bitwise shift by 12

#

(current - prev) >> 12

#

i think?

lunar cypress Feb 20, 2021, 12:09 AM

#

No

jovial warren Feb 20, 2021, 12:09 AM

#

I think the more expensive thing here is the type conversions, out of all that maths

forest pecan Feb 20, 2021, 12:09 AM

#

or other direction

lunar cypress Feb 20, 2021, 12:09 AM

#

Yes

forest pecan Feb 20, 2021, 12:09 AM

#

yeah so

#

(current - prev) << 12

#

also that returns an integer

prisma wave Feb 20, 2021, 12:10 AM

#

"other direction"

lunar cypress Feb 20, 2021, 12:10 AM

#

Wrong again

jovial warren Feb 20, 2021, 12:10 AM

#

that's a right shift lol

forest pecan Feb 20, 2021, 12:10 AM

#

oh

jovial warren Feb 20, 2021, 12:10 AM

#

you want a left shift

forest pecan Feb 20, 2021, 12:10 AM

#

lmao

jovial warren Feb 20, 2021, 12:10 AM

#

third time's the charm

forest pecan Feb 20, 2021, 12:10 AM

#

i typed it wrong

#

lol

#

there

#

(current - prev) << 12

#

((current - prev) << 12).toShort()

#

cause that returns an integer already

prisma wave Feb 20, 2021, 12:11 AM

#

Rust could do this in a single CPU cycle 🙂

jovial warren Feb 20, 2021, 12:11 AM

#

or in my case, ((newLocation.x - oldLocation.x) shl 12).toShort()

forest pecan Feb 20, 2021, 12:11 AM

#

Yea

jovial warren Feb 20, 2021, 12:11 AM

#

because Kotlin doesn't have Java operators

forest pecan Feb 20, 2021, 12:11 AM

#

that should be faster

jovial warren Feb 20, 2021, 12:11 AM

#

maybe

#

will write that down

forest pecan Feb 20, 2021, 12:11 AM

#

cause you dont need to cast to integer

jovial warren Feb 20, 2021, 12:12 AM

#

yeah

#

wait hold on though

#

what if current and previous are doubles?

#

I still gotta cast, no?

lunar cypress Feb 20, 2021, 12:13 AM

#

Casts are literally free

forest pecan Feb 20, 2021, 12:13 AM

#

Hm actually yeah you cant use bitwise really for decimals

jovial warren Feb 20, 2021, 12:13 AM

#

since you can't cast a double to a short, you gotta cast it to an int first

onyx loom Feb 20, 2021, 12:13 AM

prisma wave Rust could do this in a single CPU cycle 🙂

i agree

jovial warren Feb 20, 2021, 12:13 AM

prisma wave Feb 20, 2021, 12:38 AM

that doesn't mean it's gonna cause lag

#

Things that are called a lot get inlined anyway

Which improves performance a lot

jovial warren Feb 20, 2021, 12:40 AM

Inlined? Does that happen automatically?

prisma wave Feb 20, 2021, 12:41 AM

wait how is java both?

prisma wave Feb 20, 2021, 12:51 AM

#

I might be making this up

#

But I think bytecode is often interpreted by the JVM

#

Rather than immediately compiled

surreal quarry Feb 20, 2021, 12:52 AM

#

hm

#

interesting if true

prisma wave Feb 20, 2021, 12:53 AM

#

There's like a 50% chance I'm totally wrong here but yeah

#

Maybe a 100% chance

#

Some implementations of JVM may choose to interpret the bytecode instead of JIT compiling it to machine code, and running it directly. While this is still considered an "interpreter," It's quite different from interpreters that read and execute the high level source code (i.e. in this case, Java source code is not interpreted directly, the bytecode, output of Java compiler, is.)

#

Found this

#

I guess it depends

onyx loom Feb 20, 2021, 12:55 AM

#

interesting

#

i thought it was all jit

#

anyway as for python, its compiled into bytecode then interpreted into machine code at runtime
so yea ur right

prisma wave Feb 20, 2021, 1:12 AM

#

onyx loom i thought it was all jit

On most it would be but I think it depends on the VM

swing/awt

heady birch Feb 20, 2021, 10:00 AM

Use a border layout and add another panel into the left (or is it called west?) then give that panel a borderlayout and add a JList to the centre

sonic basin Feb 20, 2021, 10:01 AM

#

So when a player clicks an item it saves the name into the hashmap and when the inventory is created the name of the item becomes the title of the inventory the issue im having is that one key isn't doing what it should be since I'm using the event to get a player then im using the create inventory to get the player so ik the issue lies there im just not sure how to work around it

hot hull Feb 20, 2021, 10:03 AM

#

Honestly not sure what you mean by that Lazza

sonic basin Feb 20, 2021, 10:03 AM

#

alright so

#

I have a menu which when a player clicks on the item in that menu it creates another inventory, this new inventory I need to have the same title as the displayname of the item that was clicked

hot hull Feb 20, 2021, 10:05 AM

You using any gui libs?

sonic basin Feb 20, 2021, 10:05 AM

no

You should look into mf-gui, it'll make your life a lot easier

I know the way ive been making inventories so far has been long way around

Function composition

In mathematics, function composition is an operation that takes two functions f and g and produces a function h such that h(x) = g(f(x)). In this operation, the function g is applied to the result of applying the function f to x. That is, the functions f : X → Y and g : Y → Z are composed to yield a function that maps x in X to g(f(x)) in Z.
