New update.
http://www.moscafilms.com.br/mgame/demo3009.zipI left aside for now the improvements in the climb code and animation and spent some time in implementing... SOUND!
The code features:
Seamless scan of floor types in blocks, sprites, terrains and models.
Models and terrains can have soundmaps. Model soundmaps are not as accurate as terrains, but they work anyway. (It just takes more care to paint the soundmaps).
Each creature can be assigned to a 'sound_set'. Sound set is the collection of differents sounds, among them, left and right footsteps for 8 different kinds of terrain. Of course you may assign the same sound to all of them. In this case, I have only 5 sounds defined.
Other than that demo level is even more bizarre than before

The content is not priority right now. For now, it's just a soundfest.
