nice list

S

Spec-ChumOP•10/30/22, 4:37 PM

QWERTY... corresponds to what I pressed

M

MrTwix•10/30/22, 4:37 PM

excellent. thx.

S

Spec-ChumOP•10/30/22, 4:38 PM

however every key does have its own scancode

apparently not, all my custom keys return 256

SSpec-Chum all my macro keys return 256

Aqua•10/30/22, 4:38 PM

macro keys are OS dependent according to the glfw documentation so I suspect that's down to the OS

S

Spec-ChumOP•10/30/22, 4:38 PM

unless it's how the OS does it

M

MrTwix•10/30/22, 4:38 PM

edge case i supose

S

Spec-ChumOP•10/30/22, 4:38 PM

I see

Aqua•10/30/22, 4:39 PM

i suspect the macro keys on your keyboard tie into a piece of software you install alongside the keyboard

A

Aqua•10/30/22, 4:39 PM

to the computer the keys are all the same and the software is what handles it

Spec-ChumOP•10/30/22, 4:39 PM

I didn't install anything, but it is USB, so a driver was maybe installed

A

Aqua•10/30/22, 4:39 PM

interesting, i am not sure then

S

Spec-ChumOP•10/30/22, 4:40 PM

just checked - I've got 5 keyboard devices, 3 are my mouse and 2 are "standard"

S

Spec-ChumOP•10/30/22, 4:41 PM

mouse will be for the extra buttons on there, so that's not a surprise

S

Spec-ChumOP•10/30/22, 4:43 PM

according to this: https://gist.github.com/MightyPork/6da26e382a7ad91b5496ee55fdc73db2#file-usb_hid_keys-h-L172 my volume keys should be 0x80 and 0x81 but I get 0x100 for both hehe

ah ok, 0xe8 onwards is "reserved" - I'm guessing 0x100 is just GLFW default when it's not on the scancode list

Macro keys I would say are probably more driver dependent

R

Redhacker2•10/30/22, 6:41 PM

At the end of the day most of the time macro keys are just the driver faking user inputs

A

Aqua•10/30/22, 6:42 PM

i suspect so yes

Any ideas as to why this doesn't work?

AudioSpec spec;
spec.Freq = 48000;
spec.Format = Sdl.AudioU8;
spec.Channels = 2;
spec.Samples = 4096;
Random random = Random.Shared;
spec.Callback = new PfnAudioCallback((arg0, b, i) =>
{
    Console.WriteLine("Callback");
    for (int p = 0; p < i; p++)
    {
        b[p] = (byte) random.Next(0, 255);
    }
});

Console.WriteLine(sdl.OpenAudio(&spec, null));

AudioSpec spec;
spec.Freq = 48000;
spec.Format = Sdl.AudioU8;
spec.Channels = 2;
spec.Samples = 4096;
Random random = Random.Shared;
spec.Callback = new PfnAudioCallback((arg0, b, i) =>
{
    Console.WriteLine("Callback");
    for (int p = 0; p < i; p++)
    {
        b[p] = (byte) random.Next(0, 255);
    }
});

Console.WriteLine(sdl.OpenAudio(&spec, null));

AudioSpec spec;
spec.Freq = 48000;
spec.Format = Sdl.AudioU8;
spec.Channels = 2;
spec.Samples = 4096;
Random random = Random.Shared;
spec.Callback = new PfnAudioCallback((arg0, b, i) =>
{
    Console.WriteLine("Callback");
    for (int p = 0; p < i; p++)
    {
        b[p] = (byte) random.Next(0, 255);
    }
});

Console.WriteLine(sdl.OpenAudio(&spec, null));

AudioSpec spec;
spec.Freq = 48000;
spec.Format = Sdl.AudioU8;
spec.Channels = 2;
spec.Samples = 4096;
Random random = Random.Shared;
spec.Callback = new PfnAudioCallback((arg0, b, i) =>
{
    Console.WriteLine("Callback");
    for (int p = 0; p < i; p++)
    {
        b[p] = (byte) random.Next(0, 255);
    }
});

Console.WriteLine(sdl.OpenAudio(&spec, null));

It opens the device (the returned ID is 0 which seems to be fine, and it also pops when the application closes), but doesn't call the callback at all (I've tried

PfnAudioCallback.From()

PfnAudioCallback.From()

PfnAudioCallback.From()

PfnAudioCallback.From() as well and it made no difference)

P

Perksey•11/2/22, 3:49 PM

no idea, could be basically anything as these bindings are entirely untested outside of what windowing uses

A

Aqua•11/2/22, 3:50 PM

ah
hm

P

Perksey•11/2/22, 3:53 PM

i feel like our function pointer mechanism should work though

A

Aqua•11/2/22, 3:57 PM

yeah it's probably me doing something wrong
i'll take a look at how i did it in rust, it worked there, although the api was a bit different

AAqua Any ideas as to why this doesn't work? ```cs AudioSpec spec; spec.Freq = 48000; ...

T

TechPizza•11/2/22, 3:58 PM

hmm, did you not call SDL_PauseAudio?

A

Aqua•11/2/22, 3:59 PM

nope

T

TechPizza•11/2/22, 3:59 PM

then try

SDL_PauseAudio(0);

SDL_PauseAudio(0);

SDL_PauseAudio(0);

SDL_PauseAudio(0);

A

Aqua•11/2/22, 3:59 PM

lmfao that worked

A

Aqua•11/2/22, 3:59 PM

why is that nowhere in the documentation

T

TechPizza•11/2/22, 3:59 PM

yup, devices open in the paused state

A

Aqua•11/2/22, 4:00 PM

bruh

T

TechPizza•11/2/22, 4:00 PM

it is documented in

SDL_OpenAudioDevice

SDL_OpenAudioDevice

SDL_OpenAudioDevice

SDL_OpenAudioDevice

T

TechPizza•11/2/22, 4:00 PM

but not even mentioned in SDL_AudioSpec

T

TechPizza•11/2/22, 4:00 PM

i was confused as well once

A

Aqua•11/2/22, 4:00 PM

ahhh yeah i was using audiospec

A

Aqua•11/2/22, 4:00 PM

welp glad that works, ty

AAqua welp glad that works, ty

T

TechPizza•11/2/22, 4:01 PM

ok,

SDL_PauseAudioDevice(devid, 0)

SDL_PauseAudioDevice(devid, 0)

SDL_PauseAudioDevice(devid, 0)

SDL_PauseAudioDevice(devid, 0) is the new way

T

TechPizza•11/2/22, 4:01 PM

PauseAudio is legacy stuff

A

Aqua•11/2/22, 4:01 PM

ah

A

Aqua•11/2/22, 4:03 PM

right so

OpenAudio

OpenAudio

OpenAudio

OpenAudio and

PauseAudio

PauseAudio

PauseAudio

PauseAudio are legacy, and

OpenAudioDevice

OpenAudioDevice

OpenAudioDevice

OpenAudioDevice and

PauseAudioDevice

PauseAudioDevice

PauseAudioDevice

PauseAudioDevice are the new ones, gotcha
cause it only worked with that combination

A

Aqua•11/2/22, 4:08 PM

welp, awesome, sdl seems to work perfectly in my tests so time to switch my windowing system over to it

V

vetsch•11/4/22, 7:13 AM

Hey, how do I find documentation (or code) for the high-level utilities? As I understand, all the code examples are not using high-level utilities. Am I right?

L

Lyris the Kitori•11/4/22, 7:13 AM

what utility do you need help with?

V

vetsch•11/4/22, 7:20 AM

Something that provides 3D Rendering on a high-level. Or do high-level utilities just include windowing and input?
Do I have to write rendering related code for a specific backend? Or is there some abstraction ?

L

Lyris the Kitori•11/4/22, 7:20 AM

we don't provide a rendering abstraction

L

Lyris the Kitori•11/4/22, 7:20 AM

you should look at Veldrid or smthn if you don't want to write raw OpenGL/D3D

L

Lyris the Kitori•11/4/22, 7:21 AM

our HLUs are for things like math, input, windowing, etc

all my macro keys return 256
