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