There's a script that will let you punch and kick and it's kind of entertaining for like 10 mins
Dafe's Pummel Script
To stand though, to perform martial arts, that's not happening anytime soon.. the reason they get away with it in games like Dead or Alive, Soul Caliber etc. is because the martial arts are pre-rendered.. if you tried doing that in toribash, you would first need a script that would have the player
ALWAYS CATCH HIS BALANCE, and stand back up after every attack.. (think about this for a second: in most fighting games do you have to catch your balance?) it's quite possible to perform in Toribash if you have patience and you know the controls of the game, but to create algorithms for a script you would require some serious knowledge of physics.. not to mention knowledge of real martial arts.
