Since Arma 3 v1.55.133361, an alternative syntax was added to [[getDir]] that allows one to get the heading from one object or position to another object or position, the equivalent of BIS_fnc_dirTo<br>

EXAMPLE:<br>
<code>_relPos = _caller [[getDir]] _helo;</code>
is equivalent to<br>
<code>_relPos = [_caller, _helo] [[call]] BIS_fnc_dirTo;</code>

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