Be careful when using this command in conjunction with BIS_fnc_rotateVector2D, which rotates vectors counterclockwise as per trigonometric conventions, while getDir returns a clockwise angle.
To counter this, simply negate the output of getDir:[[0,1,0], -(getDir _object)] call BIS_fnc_rotateVector2D;
