datafile problem

ok now i just started using datafiles. working on a tile based snake.
im storing all my bitmaps (items, tiles, etc..) in a single .dat datafile.
through my loadmap function, i stored all my tiles id in
<code> map.layer[0].cell[j]<i>.id [/code ]
i tried drawing the map using this function, but it didn't work :

1void drawMap(){
   
int i,j;
char t_name[64];

for(j=0; j < MAP_HEIGHT; j++){
  for(i=0; i < MAP_WIDTH; i++){
  
    sprintf(t_name, "TILE%d", map.layer[0].cell[j]<i>.id);
    blit( (BITMAP*)data[t_name].dat,
          DoubleBuffer, 0, 0,
          i * TILE_SIZE, j * TILE_SIZE,
          TILE_SIZE, TILE_SIZE
          );
  
  }
}
   
19}

now im out of ideas. is there a way of solving this?
or am i totally wrong and have to redo all this again (hope not..) ?

This doesn't work because the "name" of the dat file content is a define for an index.
Try:

int first_tile = TILE0; /* or TILE1, no idea if you start at 0 or 1 */
for(j=0; j < MAP_HEIGHT; j++){
    for(i=0; i < MAP_WIDTH; i++){
    
      /* This assumes that all tiles are listed one after another in the correct order */
      blit( (BITMAP*)data[first_tile+map.layer[0].cell[j]<i>.id].dat,
            DoubleBuffer, 0, 0,
            i * TILE_SIZE, j * TILE_SIZE,
            TILE_SIZE, TILE_SIZE
            );
    
    }
  }

If this doesn't work, you can also create an array of BITMAP* and load the bitmaps using the "filename#obj_name" syntax during start-up. So have no fear, we'll find a way to get this up and running

No problem. Oh, and if you select "a problem with a specific answer" when you create a thread, you can actually mark the problem as solved and give those who helped you a virtual cookie

Coders like cookies.

No problem at all. I'll compensate by making fun of julian_boolean.. um.. I mean.. um.. never mind.
