I’m trying to play a music mod at half volume.
I thought the following sample of code would do exactly that.
I’m finding that a value of 0 passed to Mix_PlayMusic sets the volume to 0,
and any other positive value up to 128 sets it to full volume.
Mix_Music *music = NULL;
Mix_VolumeMusic(64);
music = Mix_LoadMUS(filename);
Mix_PlayMusic(music, 0);
I’m using SDL 1.2.0 and SDL_Mixer 1.2.0
A second, and even dumber problem on my part, is I can’t work out how to
protect my image data under windows when Windows is invoked while playinga
full screen game and then the game is brought to focus again.
I know I’ve seen the code on the web site for protecting hardware surfaces,
but I’ve looked a heap again and can’t find any reference to the problem.
I assume I need a thread to check for the problem or something … ?_________________________________________________________________________

You can’t. You actually have to reload the image data.

Oh dear.
How do I check when my images are lost. Can I set up a separate process, or
some sort of an event?>From: Sam Lantinga

with a -2 error code, that means that the image was corrupted. Do
all the images need to be reloaded? Are the SDL_Surface pointers
to the images I’m blitting invalid at this point? What would be a good
check on this?
I figure that if blitting returns with an error code, go through and check
all the images that need to be blitted, and then SDL_Free the surface,
then reload?
Correct me if I’m wrong, I’m just trying to comprehend…
