and this is the code

1int n;
       
  temp = load_bitmap("walk.pcx", NULL);
if (!temp) 
{
      set_gfx_mode(GFX_TEXT, 0, 0, 0, 0);
      allegro_message("Error loading bmp");
      exit(0);
  }
  for (n = 0; n < 8; n++) 
  player_image[n] = grabframe(temp,32,64,0,0,8,n);
  destroy_bitmap(temp);
   
  player = malloc(sizeof(SPRITE));
  player->x = 16;
  player->y = 490;
  player->curframe=0;
  player->framecount=0;
  player->framedelay=6;
  player->maxframe=7;
  player->width=player_image[0]->w;
  player->height=player_image[0]->h; 
   
  temp = load_bitmap("dice.pcx", NULL);
if (!temp) 
{
      set_gfx_mode(GFX_TEXT, 0, 0, 0, 0);
      allegro_message("Error loading bmp");
      exit(0);
  }
  for (n = 0; n < 8; n++) 
  dice_image[n] = grabframe(temp,64,64,0,0,8,n);
  destroy_bitmap(temp);
34 
35for(n = 0; n < 8 ; n++)
36{      
        
     //draw the background tiles
39MapDrawBG(buffer, mapxoff, 0, 0, 0, WIDTH-1, HEIGHT-1);            
           //draw the player's sprite
41draw_sprite(buffer, dice_image[n],386,420);
42draw_sprite(buffer, player_image[n],player->x-mapxoff,player->y);      
           //blit the double buffer 
44vsync();
45acquire_screen();
46blit(buffer, screen, 0, 0, 0, 0, WIDTH-1, HEIGHT-1);
47release_screen();
48clear_bitmap(buffer); 
49}//for 

there is no problem on the player_image[n] when i run the program
but will get error from the dice_image[n]...and the error appear when it run over the game loop cycle.

1) Edit your post to use the code tags.
2) Post the code to your grabframe function.
3)

Quote:

draw_sprite(buffer, dice_image[n],386,420);
draw_sprite(buffer, player_image[n],player->x-mapxoff,player->y);

Aren't you supposed to have a for loop around that?
