I think this thread proved that there is no such thing as a "standard"
character controller ;)

What kind of fighting games are we talking about here? Dead-or-alive/Tekken
stuff?

I know that Oni (and the remake whose link I previously posted) used vanilla
Quake-style controllers (NxCharacter, in the second case). It was good
enough for those 3rd person games where fighting is just one part of the
gameplay. For me, the most painful issue was "throws", where one character
has to grab and throw another. I think most games just author the 2
animations (for the player and the opponent) for a certain position, or
rather relative position between the 2 characters. At replay time they just
reposition the 2 characters so that they're at the right distance from
eachother, and then just play the animations as usual.

Do you guys know of games really doing more than that?

The problem then is when the character runs into roadblocks that

I think people just make sure the bounding volume is big enough to enclose
the whole punch motion. So it is never possible for the character to punch a
mountain wall. It sometimes makes you use 2 bounding volumes though: one to
collide against the level, one to collide against the opponents (since you
need to be close to opponents for the punch/kick attacks to reach them).

Same here. I wonder what's the most advanced thing done in games in that
respect, or if all of this is really needed (I had the impression it wasn't,
so far)
