Believe me when I say this, I'm a big fan of anything with martial arts in it. However, the lack of 3D animation tools out there makes it virtually impossible. I checked out a free tool called "anim8tor" and it came with no help files so I never figured it out. I've never had the honor of playing a darkbasic fighting game. It is possible, just difficult. I personally would like to see some pros answer your question...
