I have a car entity on an arena. The car drives well with my joystick however I want to drive it in a relative vice absoulute fashion.
AKA: I want the car to drive forward based on entity not world coordinates. I have tried both:
pXent_move(me, vector(my.x -= joy_axis(1,2) * .01, my.y -= joy_axis(1, 1) * .01, my.pan -= joy_axis(1, 4) * .01), nullvector);

and

c_move(me, vector(my.x -= joy_axis(1,2) * .01, my.y -= joy_axis(1, 1) * .01, my.pan -= joy_axis(1, 4) * .01), nullvector, GLIDE);

The car always drives in world coordinates.

Any ideas?
Thanks
