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

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)

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

AquaOP•11/2/22, 3:50 PM

ah
hm

Perksey•11/2/22, 3:53 PM

i feel like our function pointer mechanism should work though

AquaOP•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; ...

TechPizza•11/2/22, 3:58 PM

hmm, did you not call SDL_PauseAudio?

AquaOP•11/2/22, 3:59 PM

nope

TechPizza•11/2/22, 3:59 PM

then try SDL_PauseAudio(0);SDL_PauseAudio(0);

AquaOP•11/2/22, 3:59 PM

lmfao that worked

AquaOP•11/2/22, 3:59 PM

why is that nowhere in the documentation

TechPizza•11/2/22, 3:59 PM

yup, devices open in the paused state

AquaOP•11/2/22, 4:00 PM

bruh

TechPizza•11/2/22, 4:00 PM

it is documented in SDL_OpenAudioDeviceSDL_OpenAudioDevice

TechPizza•11/2/22, 4:00 PM

but not even mentioned in SDL_AudioSpec

TechPizza•11/2/22, 4:00 PM

i was confused as well once

AquaOP•11/2/22, 4:00 PM

ahhh yeah i was using audiospec

AquaOP•11/2/22, 4:00 PM

welp glad that works, ty

AAqua welp glad that works, ty

TechPizza•11/2/22, 4:01 PM

ok, SDL_PauseAudioDevice(devid, 0)SDL_PauseAudioDevice(devid, 0) is the new way

TechPizza•11/2/22, 4:01 PM

PauseAudio is legacy stuff

AquaOP•11/2/22, 4:01 PM

AquaOP•11/2/22, 4:03 PM

right so OpenAudioOpenAudio and PauseAudioPauseAudio are legacy, and OpenAudioDeviceOpenAudioDevice and PauseAudioDevicePauseAudioDevice are the new ones, gotcha
cause it only worked with that combination

AquaOP•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

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?

Lyris the Kitori•11/4/22, 7:13 AM

what utility do you need help with?

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 ?

Lyris the Kitori•11/4/22, 7:20 AM

we don't provide a rendering abstraction

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

Lyris the Kitori•11/4/22, 7:21 AM

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

vetsch•11/4/22, 7:22 AM

Ah I understand. Thanks a lot for answering

Lyris the Kitori•11/4/22, 7:22 AM

Vvetsch Something that provides 3D Rendering on a high-level. Or do high-level utilities...

AquaOP•11/4/22, 8:03 AM

if you'd like an abstraction you may wish to take a look at my pie abstraction layer, it's built on top of silk and provides both OpenGL and direct3d11 support https://github.com/piegfx/Pie

vetsch•11/4/22, 8:30 AM

One more question, the development plan mentions a Silk.NET 3.0 preview 5 (https://github.com/dotnet/Silk.NET/blob/main/documentation/proposals/Proposal%20-%203.0%20&%203.X%20Software%20Development%20Plan.md#30-preview-5). Is there a branch or release for these previews?

Redhacker2•11/4/22, 12:45 PM

The previews don't exist yet

Redhacker2•11/4/22, 12:46 PM

Reread the name of the file you just mentioned

vetsch•11/4/22, 1:17 PM

Thanks, I got confused by the tense used in the document.

Vvetsch Thanks, I got confused by the tense used in the document.

Redhacker2•11/4/22, 1:56 PM

its a check list... its going to be in present tense, that is how you write them

Redhacker2•11/4/22, 1:56 PM

kinda like step by step goals and instructions

Redhacker2•11/4/22, 1:57 PM

and targets to hit with each preview

Redhacker2•11/4/22, 1:57 PM

anyway, sorry it will be a while before 3.0 comes out

vetsch•11/4/22, 2:08 PM

. I just read "A windowing integration for MAUI has been developed" and got excited before understanding the context. Looking forward to see the preview once its ready. Thanks for answering!

Spec-Chum•11/4/22, 8:12 PM

what's the deal with GLEnumGLEnum and the "specfic" enums - I'm never sure which I'm meant to use?

Lyris the Kitori•11/4/22, 8:12 PM

both work

Lyris the Kitori•11/4/22, 8:12 PM

it's due to how gl is a c lib

Lyris the Kitori•11/4/22, 8:13 PM

basically, always prefer the specific enums

Spec-Chum•11/4/22, 8:17 PM

I do try to be fair, some overloads don't seem to accept the specific ones, TexParameterTexParameter for example, it doesn't seem to accept anything but GLEnum for the 3rd parameter

Spec-Chum•11/4/22, 8:17 PM

like this: gl.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMinFilter, (int)GLEnum.Nearest);gl.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMinFilter, (int)GLEnum.Nearest);

Spec-Chum•11/4/22, 8:17 PM

the examples do that, too

Lyris the Kitori•11/4/22, 8:17 PM

that's because it doesn't take an enum

Lyris the Kitori•11/4/22, 8:17 PM

it takes an int

Lyris the Kitori•11/4/22, 8:18 PM

so the specificity is a moot point there

Spec-Chum•11/4/22, 8:18 PM

ah, ok; why is it in GLEnum if it's not an enum? I'm far from an OpenGL expert and that's confusing lol
