Description

Description:

Searches for an empty position around a center location. The search starts looking for an empty position at a minimum distance of [radius] from the [center] and looks as far away as [maxDistance]. If a [vehicleType] parameter is specified, then the search will look for empty positions that are big enough to hold that vehicle type. If an empty position isn't found, an empty array is returned.

I think the radius parameter should be treated as a 'minimum distance' from the centre position. I found that the parameter name radius wasn't very clear. Also, if radius is greater than max distance then the function will always return an empty array. Here is an snippet of code I use to find a safe landing zone for an extraction helicopter. It may be useful for someone. _centre = [ getMarkerPos "marker" , random 150 , random 360 ] call BIS_fnc_relPos; _extraction_point = []; _max_distance = 100; while{ count _extraction_point < 1 } do { _extraction_point = _centre findEmptyPosition[ 30 , _max_distance , "UH60M_EP1" ]; _max_distance = _max_distance + 50; }; In the above example, make sure that "_max_distance" is greater than 30, otherwise the while loop will go forever.
