Arquester

Hi guys This is going to seem like an odd one but bear with me. I'm wondering whether it's possible to be able to to aim and shoot whilst descending towards the ground. The idea is that a player should be able to shoot at other characters whilst free-falling. I've already tried things like putting in the setheight command which sort of works but you can only aim up or down. Feel free to ask for more information. Thanks for looking at this and am looking forward to your replies.
