About:
My script crashes Solarus when playing music. Everything is fine on the first page, but on the second page it crashes, but not always. Sometimes some of the music slots work and other times it just crashes. The script is almost done, but this is a problem...

I tried a variety of tests. It could be a Solarus bug, wine issue, or my script.

You should not create those surfaces in the on_draw event. On the one hand, you are creating them each time the event is called, which is probably unnecessary and may slow down the game. On the other hand, on_draw is not always called, so it might happen that your surface is not created and get an error or crash when you try to access it from other function.

1. This is not the case. The same error occurs.

2. The error does not involve Wine. I tried it in my Windows 7 OS and the same error occurred.

3. I also tried tests with sol.audio.play_music("none"), but this made no difference.

4. I played the music with sol.audio.play_sound() and no crashed occurred. Sadly, I cannot stop sound with sol.audio.play_sound(), so I have a bunch of music playing at the same time.

I think it is a bug in the engine. I would think sol.audio.play_sound() would make the same crash. Kinda difficult to pinpoint the problem, but there are only few differences between sol.audio.play_sound() and sol.audio.play_music(). sol.audio.play_music() stops audio after another audio file is played and maybe that becomes overloaded somehow.

[Zefk]

I added the issue on GitHub.

Zefk, I tested your project and when I started it, it did not look like your gif image.

You should not create those surfaces in the on_draw event.

Creating surfaces at each frame is a very bad idea yes.
Solarus 1.5.1 (released just a few minutes ago!) fixes a memory leak with them, and it should be much harder to get such a crash now. (But it is still a very bad idea

[Zefk]

Zefk, I tested your project and when I started it, it did not look like your gif image.

@froggy
None of the surfaces vanish during playtest in the Solarus editor and I get no such warning.

1. Message at the beginning: "Warning: Cannot use quest size 320x240: this quest only supports 640x480 to 640x480. Using 640x480 instead."

That is normal. I wanted this.

-The entire menu, text, and buttons are offset.

That does not happen to me in the editor during playtest.

-Clicking everywhere changes the music.
- And sometimes, "Fatal: Failed to create software surface" crashes Solarus.

Those do not happen to me either in the editor during playtest.

Edit:

-Clicking everywhere changes the music.

Not everywhere, but only on the slot locations. I am not sure which you meant. I have to add a true/false, so the audio does not play before the jam station is activated.

[Zefk]

Solarus 1.5.1 (released just a few minutes ago!) fixes a memory leak with them,

@Christopho
The crash does not happen much with the new version, but I still do not understand why others are getting different error outputs and results..... Does it have to do with Windows operating system versions? I get a total crash and froggy got a surface error? Also, I get no crash with sol.audio.play_sound(), but I do with sol.audio.play_music(). I am totally confused.

Listen to what Diarandor is telling you. Just because version 1.5.1 mitigates the issue is no excuse to not fix the script. Re-creating all of your surfaces over and over again a hundred times per second is going to have unpredictable results.

Okay, so I just completely deleted the draw function and when clicking for the audio. it still crashes on the second page. This means the issue has nothing to do with the draw function.

The problem is the mouse press function. I believe the array in there for the sounds is causing the problem.  Also, I get no crash with sol.audio.play_sound(), but I do with sol.audio.play_music() as I mentioned before. That is obviously weird! This is why I reported it as a music bug.

How do I fix it?

[Christopho]

Thanks for the bug report, I will try to reproduce it and to fix it.

The remark about creating surfaces in on_draw() is unrelated with the crash you have in sol.audio.play_music(), it was the cause of other crashes in 1.5.0.
