Currently my game engine allows the player/camera to pitch and yaw, so there's no roll.
The pitch angle starts at 0°, which means the camera is facing straight ahead. From here it can go up to +85° (looking almost straight up) or down to -85° (looking almost straight down).
The yaw angle starts at 0°, which means the camera is facing east. The rotation is clockwise so 90° is south, 180° is west and 270° north. What would be 360° is 0° again obviously.
How do I get from this to the direction vector (
SetListenerPosition requires to get directional audio working?
PS: x and z are my horizontal axis, y is the vertical one.
