[SDL] Creating tiles

[Ochal Christophe]

Hi all,

I'm currently trying to write a routine to load tiles into an array of
*surfaces from a png file, but BlitSurface fails to copy the parts of
the image into the proper cells of the array.

I'm hoping someone can tell me what i did wrong.

Oh, the tiles are actually used to hold a fixed width font sized 10*10.

This is the code:


    SDL_Surface *buffer = NULL;
    SDL_Surface *tiles[127];
    SDL_Rect tilearea;
    int i;
    buffer = IMG_Load(tilefile);
    if (buffer == NULL)
       {
       fprintf(stderr, "Couldn't load %s: %s\n", tilefile, \
	SDL_GetError());
       return 1;
       }
    else
       {
       /* file loaded, blit the tiles to the proper cells */
       for (i = 0;i<127;i++)
           {
           tilearea.x = 0;
           tilearea.y = i*10;
           tilearea.w = 10;
           tilearea.h = 10;
           if (SDL_BlitSurface(buffer, &tilearea, tiles[i], \
		NULL) < 0)
              {
              fprintf(stderr, "Failed blitting the tile into the cell \
			\n", SDL_GetError());
              }
           }
       SDL_FreeSurface(buffer);
