I need to find out which direction a camera is looking at, e.g. if it is looking towards Z+, Z-, X+, or X-.
I've tried using eulerAngles, but the range for yaw goes 0 -> 90 -> 0 -> -90 -> 0 which means I can only detect if the camera is looking towards Z or X, not if it's looking towards the positive or negative directions of those axes.
