allegro help

I'm trying to make a 640x480 8bit color pacman clone using Allegro. My problem is that the colors are not being displayed correctly if I draw the lime. What could a solution be other than use some other color depth?

Thanks for your help.

Not sure if this will fix it, but try set_color_depth(8); Or is that the default?

I just tried your suggestion and it didn't help.

Try using:

void set_palette(const PALETTE p);

Passing it the same palette you used when loading the bitmaps.

I am setting the palette after the bitmaps are loaded. also, I created the bitmaps in MS Paint and saved them as the 256 color format. That shouldn't be the problem, right?

I really don't know, sorry. I always use 32 bit graphics. Is there any specific reason it has to be 8?

There's no special reason to use 8 bit other than to have my game to run almost anyones computer

Try the allegro.cc forums, I am sure someone there could help you.

Nearly everybody can run at least 16bit color depth so here is a way to get max color depth on everybody's computer...

Code:

ofstream filelog("log.txt");

set_color_depth(32);
 if(set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 800, 600, 0, 0) == 0)
 {
 filelog << "\nset_color_depth(32) initialized";
 filelog << "\nset_gfx_mode(GFX_AUTODETECT_FULLSCREEN 800x600) initialized"; 
 }
 else if(set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 800, 600, 0, 0) != 0)
 {
 filelog << "\nset_color_depth(32) failed";
 filelog << "\nset_gfx_mode(GFX_AUTODETECT_FULLSCREEN 800x600) failed";
 
  set_color_depth(24);
  if(set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 800, 600, 0, 0) == 0)
  {
  filelog << "\nset_color_depth(24) initialized";
  filelog << "\nset_gfx_mode(GFX_AUTODETECT_FULLSCREEN 800x600) initialized"; 
  }
  else if(set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 800, 600, 0, 0) != 0)
  {
  filelog << "\nset_color_depth(24) failed";
  filelog << "\nset_gfx_mode(GFX_AUTODETECT_FULLSCREEN 800x600) failed"; 
  
   set_color_depth(16);
   if(set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 800, 600, 0, 0) == 0)
   {
   filelog << "\nset_color_depth(16) initialized";
   filelog << "\nset_gfx_mode(GFX_AUTODETECT_FULLSCREEN 800x600) initialized"; 
   }
   else if(set_gfx_mode(GFX_AUTODETECT_FULLSCREEN, 800, 600, 0, 0) != 0)
   {
   filelog << "\nset_color_depth(16) failed";
   filelog << "\nset_gfx_mode(GFX_AUTODETECT_FULLSCREEN 800x600) failed";
   }
  }
 }

filelog.close();

Btw, I was only doing the filelog stuff because I wanted to see what color depth each computer would be going to.

Btw numero dos, I have no idea how effective this really is except that it hasn't failed on me once yet. It may cause problems under certain circumstances; I have no idea.
