Hi I want to know how would you be able to create close to real flight simulation like a commerical airplane and the space shuttle ect.. Would I be able to use the newton engine.
It is a big topic, and depends on your knowledges about plane physics.
In short, you can maneuver your plane using "phent_addtorquelocal", fly your plane using "phent_addforcelocal", look up these functions in the manual for details.
Depends on if you intend on using 3DS physics or not. I recommend trying it first, if it overwhelms you or otherwise doesn't work for you, go for Newton
