I started a new project today, prototyping an addition to a game engine I already have. I pretty much took over all initialization code and the basic objects from the existing code (which works fine), but stripped the unnecessary parts out (like animation code, as I don't plan on animations on the prototype for now)

The dumb thing is, that it doesn't want to load the tileset...
All source code's in the attached zipfile, along with the tileset. The problem lays in either

Tile::Tile() : /* deze methode is sneller dan wanneer ze in de constructor staan */
size(32),
type(0) {
  if(!m_tile) load_tileset("Gfx/Tile.bmp"); 
  if (!m_tile) cout << "Spritesheet not loaded\n";     
}

(file classes.cpp)
or in

void Tile::load_tileset(const char *tileset) {
  Tile::m_tile = load_bitmap(tileset, NULL);
}

as the output always gives: "Spritesheet not loaded".

m_tile is a static, protected bitmap in Tile, btw.

I only got one version. What're the errors it gives there? Might have something to do with the problem.

The IDE I use, is Dev-C++ v.4.9.9.2, with the standard compiler coming with it and with the Allegro linker parameter.

Got some trouble with placing the virtual int get_index() part. It keeps saying "virtual outside class declaration"

The problem's with loading the spritesheet;) If I reinstate the draw-function, the program crashes as it doesn't load the bitmap.

Ok, thanks. I'll read up on it.

Hmmm, I went through all the tutorials, but they didn't tell me how to fix the spritesheet loading. It was an interesting read, though.

Yeah, but so do I in my other code, and it all works, both in that other code and in that tutorial, but I do the same thing in this code, but it doesn't work here =S

Hmmm... same thing for the other code (the one from that thread from yesterday), or'm I missing something? That one worked. This one compiles (here, at least), but doesn't work in runtime, so there must be a difference somewhere which I can't spot.

What errors's it give there when compiling?

How'm I supposed to fix these errors if my compiler doesn't give any and if you don't tell me what they are when you notice them????

I've tried running it from Dev-C++ right after compiling, from inside the directory, and from inside the other code's directory (which uses the same subfolder and spritesheet's filename), and it all does the same.

Ok, file_exists didn't quite work (didn't want to compile, and if I added 0, NULL, it gave runtime crashes), so I did it like this:

     FILE * file;
     file = fopen(tileset,"r");
     if (!file) cout << "Error with opening of file\n";
     else cout << "Could open file\n";
     fclose(file);
      
     if( (Tile::m_tile = load_bitmap(tileset, NULL)) == NULL)
         cout << "PROBLEM!\n";

The output of this is:
Could open file
PROBLEM!

So it can reach the file, but something's wrong with the load_bitmap part. Not much that can be done wrong with that, though =S

I don't know how to compile with the debug version. Color depth's set to 16. Set_color_conversion's not called. The graphical mode's set like this:

    set_color_depth(16);
    if(set_gfx_mode( GFX_AUTODETECT_WINDOWED, SCR_WIDTH, SCR_HEIGHT, 0, 0)) exit(1);
    buffer = create_bitmap(WIDTH*32, HEIGHT*32);

That's the same as in the other code, where it does load the tileset.

I also tried loading the tileset from the other code, and that gives the same problem.

You should write a simple test case to load the bitmap and blit it to the screen in as few lines as possible. Don't put the bitmap in a subdirectory or anything, just load and blit. I want to see if this is a problem with Allegro.
