I think you should get the camera offset from the player in X and Y values, and start calculating distances/angles from there, which will then get broken in 3.3.5. So screw camera distance, since you can't do triangulation math on it in 3.3.5 anymore.
I'll experiment tomorrow with resolution and FOV.
