**Z angle returns a value from 0 to 360 depending on the player's current heading. Z angle is measured with the positive ''y''-axis as 0 and increasing clockwise from there. In the Wasteland worldspace, this is North, however, the same is not true of interiors (other exterior worldspaces have not been tested) - GetAngle is based on the game's coordinate system and the Compass is based on the NorthMarker object in each cell. Therefore, GetAngle Z is only useful for determining compass directions in the exterior Wasteland worldspace.
**'Player.GetAngle X' returns a value (theorically) from -90 to 90.  The true in-game range is -89 to 89, with -89 if the player is looking above himself, and 89 if player is looking at his feet. Note that the player actually ''is'' looking 89 degrees above or below horizontal - you cannot look exactly up or exactly down in game.
**Trigonometry with the Z angle could be done using the following conversion formula:

**The in-game angles are not the same as the world standard interpretation of angles. Trigonometry with the Z angle could be done using the following conversion formula:
  float GetAngleZ  ;the game's version
  float GetAngleZ  ;the game's version
  float TrigAngleZ ;the rest of the world's interpretation of the same
  float TrigAngleZ ;the rest of the world's interpretation of the same
