when a fighter hits another fighter..that's basically what collision detection is.
Imagine two spheres in the arena instead of fighters(or bubbles around the fighters)..when the two spheres get close enough you get a reaction...that reaction is the result of collision detection. Whether it be a punch or kick, all that depends on what button you press. In MKDA it just seems sloppy..when i compare it to games like DOA,VF4 or tekken.
