Bank: $A3
Enemy projectiles: None

Parameter 0: Unused
Parameter 1: Direction
    0: Down
    1: Up
Parameter 2: Y position if entered room by elevator. Normal Y position is used as target Y position in this case

Downward elevators must have process whilst off-screen bit set
}


;;; Behaviour ;;;
{
In block collision: if collided with block whose door header pointer is 0..7FFFh, then elevator properties = standing on elevator.
In enemy AI: if standing on elevator and pressing up/down, then lock Samus (7) and move up/down with her indefinitely.
Eventually Samus will collide with an actual door.
In the hit a door block state: door is an elevator, so lock Samus (0) and wait 48 frames if downwards elevator.
In door transition state:
    if upwards elevator then lock Samus (0), else lock Samus (7).
    The door is an elevator flag is set (by the door header) and Samus is locked.
    The elevator status is set to door transition.
In enemy init AI: elevator status == door transition, so enemy Y position = [enemy parameter 2].
In enemy AI: keep moving until reached original enemy Y position, then unlock Samus (Bh).
