Description:: Returns a position that is a specified distance and compass direction from the passed position or object.
In Arma 3 use getPos' alternative syntax instead.
Execution:: call
Groups:: Positions Geometry

Syntax:: [origin, distance, direction] call BIS_fnc_relPos
Parameters:: origin: Object or Position - object or position which should be used as initial point.
: distance: Number - distance from initial point
: direction: Number - direction from the intial position
Return Value:: Position

Example 1:: [[0,0,0], 1000, 50] call BIS_fnc_relPos; // [766.044,642.788,0]

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 rangefinder (which is measuring in 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.
