creating a Flying Pawn like a fish in sea

[Chathura]

actually what i want to create is a Blood Cell.. in my game the player is a blood cell, and he can fly ( or call it swim ) in the level anywhere...
i want it to be able to go up and down in the same way we use mouse to move left and right while holding 'w' key. and rotate it self if another certain button is pressed.. (like controling an aircraft).

i want this to be done on the pawn. not vehicle.

can someone give me some good advices on how to do this or direct me to a good tutorial...?

Thank You.

use PHYS_Flying
you can script a pawn to use this or use the console command fly.
to see it in action, start a game, press tab, type in 'fly' (without the ' ' )
or use the console command kismet node
