Syntax:
GetAngle axis
Example:
GetAngle Z
Returns the current world rotation angle of the object on the selected axis (X, Y, or Z) in float.
Special Notes (relative to GetAngle called upon the player)
- 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 Tamriel 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 Tamriel worldspace.
- Trigonometry with the Z angle could be done using the following conversion formula:
float GetAngleZ ;the game's version float TrigAngleZ ;the rest of the world's interpretation of the same set GetAngleZ to player.GetAngle Z if ( GetAngleZ < 90 ) set TrigAngle to 90 - GetAngleZ else set TrigAngle to 450 - GetAngleZ endif
- 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: 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.
