help with spawning caches in buildings.

[HFTB 1]

i currently have several caches which are grouped to an assortment of markers at which they can randomly spawn. but i'm curious whether there exists a simple script or other method which can place the caches at a random location (from a pre-defined list, similarly to how grouping with multiple markers works) INSIDE a building. the idea is for there to be several compounds/villages where the caches might exist, and for those locations to require house-to-house searching in order to find the caches.

thanks for any help with this.

I use the fn_getBuildingPosition from rübe, http://forums.bistudio.com/archive/index.php/t-102796.html and randomly select a position from it:

     _positions = [_b] call fnGetPositions;
     _pos = _positions call BIS_fnc_selectRandom;
     _cache setPos _pos;

_b holds the building object, _cache the cache.
