Remove the "if e.type == KEYDOWN" and call "chiave" on every iteration.

Then change the function to:

def chiave(hero,key):
         hero.direction = -1
         if key[K_DOWN]:
             hero.set_directions(0,0,1)
         elif key[K_UP]:
             hero.set_directions(1,0,-1)
         elif key[K_LEFT]:
             hero.set_directions(2,-1,0)
         elif key[K_RIGHT]:
             hero.set_directions(3,1,0)
         if key[K_RETURN]:
             if not hero.battle:
                 hero.battle = 1

This way, if no direction key is pressed, the direction is set to -1.
