A vehicle's z-angle cannot be retrieved in r2.

You can do /s and read it from the chatbox.

There is a complicated method. Though I would not guarantee its accuracy.

Fetch X,Y pos of the car.
Lets call them X1, Y1.

Accelerate the car in forward direction (without turning).
Stop the car.
Fetch X,Y pos again.
Call them X2, Y2.

Angle = tan^-1 [ (Y2 - Y1)/(X2 - X1) ]

You can use a timer to get X2, Y2 while you are driving.

Well, the angle (if in radians) would have to be converted to a degree measure out of 360. Regardless, that wouldn't capture the facing (vehicle z) angle.

+ tan is periodic for (-Pi/2, Pi/2) so it will return the same value for 0 degrees and 180, so without more IFs, he won't get the angle anyway.

I really thinks that /s should do everything, cmon! I use it sometimes even if I need some player pos + angle for single player modifications ::).

Or have you thought about player angle? If it works, just set your character, return it;s angle and set it to your car.
