Works great in multiplayer. The numbers are representing offset as follows : [X axis,Y axis,Z axis] The return array can be processed-converted into degrees as follows: _array = _this weaponDirection "weapon class"; _dir_degrees = (_array select 0) atan2 (_array select 1);

WeaponClass can only be the primary turret of the vehicle. For example it is not possible to get direction of commander's M2 on M1Abrams.

For an alternative to the weaponDirection command, see the following post on the official forums. On how to obtain the direction of multiple turrets on vehicles. Turret Animations (dead link) - new forum
