* player can only aim diagonally down while airborne
** player's body animation is 8 frames long, while gun animation is 4 frames long. 
in this case, the gun animation just plays twice. if possible, it's good to make sure their 1st frames match.

*** when player stands on the ground, body anim vacuum plays simultaneously as gun vacuum anim, but
when player is airborne, the same vacuum gun animation is used, but the body uses a single frame (refer to player_02.txt)
