would it be physics based? Could i get away without using physics?
Here's a few tid bits i picked up:
-The plane always has a little bit of gravity, but only when it's thrusting.
-If you are thrusting while facing down, you don't necessarily go faster than if you weren't thrusting
-when you're gliding in one direction, then you turn and start to fly in another direction, It has some elasticity. I can't think of how to mimic that.
id ideally like to use something other than the physics for performance reasons, but i can't think of any other way
