Since Arma 3 v1.55.133361, an alternative syntax was added to [[getPos]] that allows one to get a position that is a given distance and heading away from original object or position, the equivalent of BIS_fnc_relPos<br>
<br>
Example:<br>
<code>_relPos = _caller [[getPos]] [([[abs]] _boundingBoxDimensions) -0.2, _direction];</code>
// RESULT: 0.0021 ms<br>
<br>
is equal to:<br>
<code>_relPos = [_caller, ([[abs]] _boundingBoxDimensions) -0.2, _direction] [[call]] BIS_fnc_relPos;</code>
// RESULT: 0.554324 ms

Lawman Actual
The function appears to work in two dimensions, and as such can be used to find the position of a target relative to the player if bearing and distance are known. However, if there is a significant change in elevation between yourself and the target, the distance registered on a ragefinder (which is measuring a 3 dimensional straight line) will always be larger than the two-dimensional value required for BIS_fnc_relPos and as such air-strikes and ordnance called in using such a function can miss by several hundred metres in extreme cases. Currently searching for a method which incorporates the azimuth of the rangefinder in calculation.
