github is trying to shill their dumb ai thing while im trying to read code

Image attachment

doesn't look particularly in the way (edited)

Copilot is actually quite useful

04:34

Idk if you can call it an ai

04:35

It works more like advanced autocomplete

It is basically gpt

github is trying to shill their dumb ai thing while im trying to read code

aye eye

@Ryozuki i don't really have any good question sadly. So i ask a meta question: Are you sometimes split about your feelings while coding: Fck anything i just do it quick & ugly now. And then on the other side you remember how awesome it is, if you carefully planned everything and it works out.... in rust xd

oh ye

08:28

i love idiomatic over engineered rust

08:28

thats why on advent of code i do it like that

08:28

xd

08:28

remember?

i dunno, i dont follow advent of code xd

Good thing ddnet doesn't use any game enginr

it uses teengine

its powered by slaving tees

Man i really need the access to teeuniverse GitHub organization xd. I want to use it to host mod code, and have a fancy fitting name

i remembered i had ryocrater

i feel the urge to make my game engine with it now

so many urges, nothing finished

We have to fix that issue first then all the others should be doable

Maybe it makes no fun anymore then xd

why not?

closed source is king

13:28

but maybe they have troubles with bots xd

they're probably operating with a whitelist, but sad that github isn't on it yet

@heinrich5991 Hey, I'm furo from #7181. I kinda have no clue how I would introduce the new server packet. Where would I start?

you can check datasrc/network.py

15:02

add a message at the bottom, you can take a look at the existing messages

I did take a look, could I extend the "Sv_VoteStatus" message? or should I create a new one?

the messages that don't have a long name with an @ inside are not ours and shouldn't be extended

15:04

you can either add a Sv_VoteStatusEx at the bottom that contains all these fields plus the one you want to add

15:04

or just add a Sv_YourVote that contains just your vote

15:05

I'm not sure entirely what's the better option

15:05

intuitively, I'd guess it's the first one, but not sure

NetMessageEx("Sv_VoteStatusEx", "votestatus@netmsg.ddnet.tw", [
  NetIntRange("m_Yes", 0, 'MAX_CLIENTS'),
  NetIntRange("m_No", 0, 'MAX_CLIENTS'),
  NetIntRange("m_Pass", 0, 'MAX_CLIENTS'),
  NetIntRange("m_Total", 0, 'MAX_CLIENTS'),
  NetIntRange("m_Voted", -1, 1),
]),

Kinda like this?

yes

15:12

make it @netmsg.ddnet.org though

15:12

we changed domains

15:12

sorry, no example of this in the file yet

Sure, next step would be to generate the other files I assume? How would I do that?

it happens as part of the build, you don't need to worry about it

15:19

you can simply start using the message

i recommend building to get autocomplete tho

@Jupstar ✪

crab still sucks

@Jupstar ✪ how to allocate in the host and give to guest

16:05

#[repr(C)]
struct Game {
    data: [u8; 32],
}

16:05

mem.grow(&mut store, bytes(std::mem::size_of::<Game>()));

16:05

this? xD

16:07

i guess u need to take the offset before growing

16:07

so u know were to write?

Ryozuki

mem.grow(&mut store, bytes(std::mem::size_of::<Game>()));

if u did this once, then always write to this offset

16:08

where it grew

ok

heinrich5991

you can simply start using the message

I created Sv_YourVote instead, my question now is. How would I support servers that don't send this packet? Do I create a GameInfoFlag?

Keep the first vote highlighted until you receive Sv_YourVote which can override it. This behavior is compatible with old and new servers. The server can check the client DDNet version to decide whether it should (accept re-votes and) send Sv_YourVote. (edited)

exactly what Kaffeine said

@Jupstar ✪

16:41

did u use ExternRef

Ryozuki

did u use ExternRef

no, what does it do

idk

16:43

An opaque reference to some data. This reference can be passed through Wasm.

i do it a bit different from what u learn in the examples anyway

the thing is

16:45

no examples for complex stuff

16:45

such as calling a function passing a non copiable struct

16:45

xd

yeah.. it's pretty annoying

16:45

to get into it

in wasm guest

16:45

u make the function accept a offset?

16:45

and u convert it to a ptr?

16:45

?

16:45

what i do here is

16:45

i have struct X

16:45

i turn this into a ptr u8

16:46

and write it to wasm memory

16:46

i know the offset

16:46

now i have a guest function

16:46

that i want to take this struct

16:46

or a ptr that can be converted to it

16:46

using the same layout

16:46

is the ptr the offset?

well that is probably the fastest way.. but i think it's a bit harder i do it differently: i prepare the memory inside the guest, and the guest tells me the ptr then i write into the wasm linear memory this way i can easily have multiple parameters growing independetly

Ryozuki

i turn this into a ptr u8

sadly this can cause troubles

16:47

1. 32bit 2. no guarantee from rust

16:47

but for testing it's probably enough

16:47

i use a serializer

Servo is a web rendering engine written in Rust, WebGL and WebGPU capable, and adaptable to desktop, mobile, and embedded applications.

Jupstar ✪

1. 32bit 2. no guarantee from rust

well my struct is repr C and packed

16:48

so u cant read uninit padding bytes

16:48

which is ub in rust

yeah but e.g. usize

Ryozuki

https://servo.org/blog/2023/09/15/upcoming-events-and-new-browser-ui/

omg would be so cool if servo would be good

16:50

i actually just want their HTML + CSS engine xD

xd

Jupstar ✪

yeah but e.g. usize

yeah but the ptr aka offset is u32 anyway

16:50

ima test

16:51

#[derive(Debug, Clone)]
#[repr(C, packed)]
pub struct Game {
    pub data: [u8; 32],
}

16:51

i have this in a middle crate "interface"

16:51

let play_game = instance.exports.get_typed_function::<u32, u8>(&store, "play_game")?;

    let pages: Pages = Bytes(std::mem::size_of::<Game>()).try_into().unwrap();
    let offset_game = mem.grow(&mut store, pages)?.0;

    let game = Game {
        data: [1; 32],
    };
    let game_ref = addr_of!(game) as *const u8;
    let game_ref = unsafe {
        std::slice::from_raw_parts(game_ref, std::mem::size_of::<Game>())
    };


    mem.view(&store).write(offset_game.into(), game_ref)?;

    let result = play_game.call(&mut store, offset_game)?;

16:51

my host code to setup the struct ref

16:52

#[no_mangle]
pub fn play_game(game: *const u8) -> u8 {
    assert!(!game.is_null());
    let game: Game = unsafe {
        std::ptr::read(game as *const _)
    };
    game.data[0]
}

16:52

guest code

16:53

ok wait

16:53

my guest is wrong probs xd

16:56

#[no_mangle]
pub unsafe fn play_game(game: *const Game) -> u8 {
    assert!(!game.is_null());
    (*game).data[0]
}

16:56

     
Running `target/debug/host target/wasm32-unknown-unknown/debug/guest.wasm`
[host/src/main.rs:56] &result = 1

16:56

@Jupstar ✪ omg

16:56

it worked!

epic gamer moment

if i change data to 2

16:57

it prints 2

16:57

@Jupstar ✪ but doesnt ur way make the wasm module allocate everytime its called

Ryozuki

@Jupstar ✪ but doesnt ur way make the wasm module allocate everytime its called

i call resize on a vec<u8> so it allocates it only if the vec wasnt big enough yet

hm

16:58

it works with game: &Game

16:58

too

16:58

xd

16:58

but idk if im in ub territory here

a reference is a pointer

yeah

well u could say since u in a wasm module it's not UB xd

well it would be ub if the host passes a null offset

16:59

or smth that doesnt point to a valid game

17:00

xd

17:00

true

17:00

wasm anti ub

17:01

@Jupstar ✪ the memory is not read only on the guest side right

17:01

and no way to do that i guess

17:02

if i would need to rewrite that memory pos every time i call it with the original to be safe

Ryozuki

@Jupstar ✪ the memory is not read only on the guest side right

yes u can modify it as u wish

yeah

17:03

im asking if there can be read only memory

externalref sounds like read only memory xd

17:04

but no i think there is no read only memory
