SunVox for ZGE

[Rado1]

Today, I tested ZGE with the latest SunVox DLL 1.9.3. It works fine.

[Ats]

So I started toying with SunVox, which is quite amazing. Everything works on PC and Android ( latest lib 1.9.4c).

I'm still learning the basics, therefore I try to load some examples. The problem is that musics plays on ZGE, such as "Boomlinde - Caravan.sunvox", while others don't play at all, or even make ZGE crash. Do you happen to know what is causing that? Is it coming from a custom and rather complicated module, or from the number of tracks, or something else?
Because everything works fine in SunVox, so I'm not sure if the problem comes from ZGE or the sunvox.dll
Thanks for your knowledge on the subject

Edit:
Thanks to Kjell, now I know that everything is fine with SunVox. I spent one hour this morning to try all the example songs and classify them into subfolders such as OK, BAD (all instruments are messed up), NO (not playing), CRASH (crashes ZGE). Turns out that the problem was coming from the computer
I'll try that computer again tomorrow morning and try to discover what's going on with it.

I just made a test in order to only play the bass line at some point. But I'm not sure what would be the best method to do that.
I thought of 3 methods (you can set the method number in *Onloaded/ZExpression", just press space to mute the song and keep the bass)

Method 1:
By using two files, I play the Song and the Bass at the same time on two different tracks. Then I play with the volume on the Song track.
This is working great, but I wonder if they will still be coordinated and play at the same time...

Method 2:
I also use two files. One being the complete Song, and the other just the Bass. I play the first file, then I stop it and play the Bass starting from the timecode where the other file stoped. The problem is that I don't know how to get that timecode, since SunVox run with custom Ticks.

Method 3:
I just use the complete song File and I mute paterns (or modules?) directly in it. But I have no clue how to retrive such a thing from the file.

Hi Ats,

I just made a test in order to only play the bass line at some point. But I'm not sure what would be the best method to do that.

You can use the sv_send_event function. Attached is a simple example ( use the left-mouse-button to toggle the "melody" on and off ).

Thanks Kjell
I think I get it. It will be a bit more complicated to handle that method with several music files but it's very efficient!
Where did you find that 0x0100 is the for the volume? In SunVox source code?

Hi Ats,

Where did you find that 0x0100 is the for the volume? In SunVox source code?

From the original header ( sunvox.h ) included with the SunVox library.

Code: Select all

/*
   sv_send_event() - send some event (note ON, note OFF, controller change, etc.)
   Parameters:
     slot;
     track_num - track number within the pattern;
     note: 0 - nothing; 1..127 - note num; 128 - note off; 129, 130... - see NOTECMD_xxx defines;
     vel: velocity 1..129; 0 - default;
     module: 0 - nothing; 1..255 - module number + 1;
     ctl: 0xCCEE. CC - number of a controller (1..255). EE - effect;
     ctl_val: value of controller or effect.
*/
int sv_send_event( int slot, int track_num, int note, int vel, int module, int ctl, int ctl_val ) SUNVOX_FN_ATTR;

Volume is the first "controller" of the SpectraVoice module, hence a value of 0x0100 for the "ctl" argument.

Hi everyone. I'm back on track with ZGE, trying to continue Omeganaut.
So here's my new problem: when I play on the game on Android and press the Android Navigation home button, the game is paused, normal, but the SunVox player continue to produce music. How should I pause the music too ?
I believe it has to do with the zegAtcivity.java onPause() function that, maybe, should pause the libsunvox.so library ?
Or is it something else?

Thanks for your help

[Rado1]

Hi Ats. Also for me it's a long time ago when I touched ZGE. However, you can try to use the KeyPress component. If you read its help page, it's saying that CharCode 255 represents loosing of application focus on Android. So calling sv_stop() from embedded ZExpression should work. Similarly, CharCode 254 means that the application got focus, so you could call sv_play() to resume playing.

[Ats]

Wow, that was a quick response. I'm glad you're still here Rado1
I'm going to try that.

Edit: And it's working perfectly ! Thanks

[VilleK]

Hi guys. Good it was solved

[Ats]

Hi, I'm trying to run my test ZgeSunVox.zgeproj in linux, but I don't know what to do with the sunvox.so library...
My ZgeSunVox.zgeproj test won't launch on Linux even though there's the x86 sunvox.so in the same folder. How is it supposed to work?

Since linux is case sensitive, I tried to rename sunvox.so to SunVox.so but it's not working either.

I also tried copying sunvox.so to

Code: Select all

/usr/local/lib/
/usr/lib/
/lib/

without success...

I also tried everything I could do with LD_RUN_PATH to search the lib somewehere before launching ZgeSunVox.

Do I need to link the library during the build? Maybe with upx? The SunVox linux program is working without the library, so I guess the library is merged with the executable!?

[Rado1]

Unfortunately, I do not have Linux, so cannot help you much. Probably Ville could. On windows, the library should be included in the same directory as the project/exe file.

[Ats]

Too bad, as I was kind of expecting you to help me compile ZgeBullet library for linux in my next step

So I'm currently reading this: https://aimlesslygoingforward.com/blog/ ... -on-linux/
It's interesting and comprehensible. But the weird thing is that there's no trace of sunvox.so in my ZgeSunVox test:

Code: Select all

readelf -d ZgeSunVox

Edit:
I just tried renaming the ZExternalLibrary ModuleName from "SunVox" to "sunvox", but also "sunvox.so", which prevents the Windows version from running.
On linux, the terminal just trace that ModuleName then the app shuts down...

[Kjell]

Hi Ats,

The ZExternalLibrary component loads a external library at runtime. On Linux this is done using dlopen. Have you tried prefixing your ModuleName with a "/" so it looks for the .so file in the directory of your executable?

K

[Ats]

Thanks for the hint. I finally got something different. I had to type "./sunvox.so" for the ModuleName. Same as Android libs in fact...

So I get a new crash:

Code: Select all

Desired audio buffer size: 2048 frames

ALSA HW Rate: 44100 frames

ALSA SW Start threshold: 1
ALSA SW Stop threshold: 4096
An unhandled exception occurred at $ADD8D1FE:

  $ADD8D1FE

The address code is different at each and every crash. But I managed to find where it crashes:
sv_load_from_memory(0, MusicFile.FileEmbedded, MusicFile.Size);
Which is working on Windows and Android.

I also tried to load an external file instead with the exact same result:
sv_load(0, "./completedestruction.sunvox");
