at least now you can fix the behavior and display.
If you want, I can test it on my console.

Well, here's the compiled version. There is one thing that doesn't work on the emulator and that's the wave part.

I think I am almost there.
Currently I get this error:

I typed "make" in cmd, and it shows the appropriate message:
"make: *** No targets specified and no makefile found. Stop."

What am I missing? Python seems to be installed correctly, Netbeans configured properly, and ENV VARS all good to go (though I could be wrong).

I'd assume it is just as the error states, there is no makefile. What are you trying to compile?

Mmhhh i don't know why it doesn't work, it seems all wav settings are right :/
This is the wav file i used for the sample script: http://rinnegatamante.netsons.org/blood.wav

(To extract wav files i used for my samples i used ffmpeg)

It seems i found a bug in my openWav function (i was using an old version of my interpreter for my tests where header was read statically and not dinamically so i hadn't see this mistake :/ )... Try this,replace this:

Code:

    pos=pos+jump;

With this:

Code:

    pos=pos+4+jump;

Remember to use only mono wav files, stereo wav audio will be broken for now, i'm working to add stereo support.

Press A stops the movement instead of making it slow.

The cubes are moving very fast and are very spaced from each others.
maybe that's why you don't see the "wave", each dots are moving too fast to see them on screen?

collision detection is working.

They move 2 pixels each frame. I think there are 60 frames per second byt I think this is too much for wave.

Goodnight sirs,
Can someone tell me the (technical) reason why on new 3DS, homebrews can't have sound yet, and if we can keep hope for sound working on new 3DS in the future?
Thanks!

Can anyone tell me whats causing this to freeze?

I don't have a working emulator to run it in.

Add this before playsound:

Code:

GSPGPU_FlushDataCache(NULL, audiobuf, size-(pos+4));

Does exist some kind of limitation for FSFILE_Read function? I'm working to reproduce stereo wav files but it seems this cycle never end, if i comment the FSFILE_Read calls, it ends fine):

Code:

wav_file->audiobuf = (u8*)linearAlloc((size-(pos+4))/2);
    wav_file->audiobuf2 = (u8*)linearAlloc((size-(pos+4))/2);
    wav_file->size = (size-(pos+4))/2;
    u16 bytepersample;
    int sample;
    FSFILE_Read(fileHandle, &bytesRead, 32, &bytepersample, 2);
    bytepersample = bytepersample / 2;
    int i = pos+4;
    int j = 0;
    while (i < size){
    FSFILE_Read(fileHandle, &bytesRead, i, &sample, bytepersample);
    wav_file->audiobuf[j] = sample;
    i=i+bytepersample;
    FSFILE_Read(fileHandle, &bytesRead, i, &sample, bytepersample);
    wav_file->audiobuf2[j] = sample;
    i=i+bytepersample;
    j=j+bytepersample;
    }

Well, it didn't freeze this time. It just crashed and restarted the system

Rinnegatamante · Dec 14, 2014

:/ Retry my lpp-3ds script with this executable and tell me if wav starts correctly: http://rinnegatamante.netsons.org/lpp-3ds.3dsx

Agent Moose · Dec 14, 2014

It gives an error saying:

Error: [string "?"]:3: bad argument #4 to 'playWav' (number expected, got no value)

(I really like the font you had used for the text, nice and clear)

Do we have the ability to detect if the 3ds lid is closed?

Little adaptation for new function, change playWav line in index.lua with this:
Sound.playWav(test,NO_LOOP,0x08,0x09)

Agent Moose · Dec 14, 2014

Finally it works!

That took forever~

Sound.openWav function works with the source you used in C, sounds strange it doesn't work...

Agent Moose · Dec 14, 2014

No clue why it doesn't work. And I can't exactly figure out blargSnes' audio :\
