G.T.A.2 Map Editor

[hwnd]

The world is 256 * 256 * 8 (X,Y,Z) always, just the blocks and their faces matter. Some faces are textured some not.
I only check for AIR blocks that contain no faces, this speeds things up a bit.

Map has 8 "layers" (0..7) in Z coord, from top to down. Its a top down view game.

Looping through ~500 tiles and getting TBITMAP for them and then doing pixel stuff on them is pretty slow.
Maybe i should reuse the actual texture data i already created from tiles. Instead of doing another read for same tiles second time.

I once talked about here how one GTA1 editor shows so nice minimaps. It only works on Win9x. Fails on NT with "Failed to create empty document". MFC app. I will try to get the BMP of minimap and analyze that. Maybe i will figure out how he is able to create minimap so fast or at least whats the tehnique, will try to analyze some area of minimap and actual tiles that are used in map at the same place.
