nested arrays

[Desrat 0]

ok I have a nested array in this sort of format (forget the contents this is an example)

array = [[1,2,3],[4,5,6],[7,8,9],[10,11,12],[13,14,15]];

I then use the following to grab one of the arrays at random

target = array call BIS_fnc_selectRandom;

I would then like to delete the selected item from the original array, so how do I find out what index number has been selected by the BIS_fnc_selectRandom function so that I can delete it (oh and I'm aware it needs making a non array variable first as per the biki instruction) just need to know the index number.

I don't understand. Why don't you just delete what BIS_fnc_selectRandom returns? If you want a random index number, you can just use:

floor(random(count array))

Why not just pick the index yourself, grab the data and remove the entry. Sometimes it just simpler to make your own.

/* ARRAY call TakeRandom */
TakeRandom = {
   private ["_c", "_idx", "_data"];
   _c = count _this;
   _idx = floor random _c;
   _data = _this select _idx;
   //move swap with very last item
   _this set [_idx, (_this select (_c - 1))];
   //shrink array
   _this resize (_c - 1);
   //return data
   _data
};

thats a fair point :)
