*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.

*Trigonometry with the Z angle | ** In the Tamriel worldspace, a Z angle of 0 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 Tamriel worldspace. | ||
** Note that standard mathematical notation has 0 starting on the ''x''-axis, rather than the ''y''-axis, and increases counter-clockwise, not clockwise. Trigonometry with the Z angle thus requires using the following conversion formula: | |||

*X angle 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. | * X angle returns a value (theorically) from -90 to 90.

*NOTE: You can rotate the camera when riding a horse without changing the actual direction the player's facing so GetAngle Z is kind of useless sometimes (like when using [[getLOS]]) if the player is on a horse. | * NOTE: You can rotate the camera when riding a horse without changing the actual direction the player's facing so GetAngle Z is kind of useless sometimes (like when using [[getLOS]]) if the player is on a horse. | ||
