selectRandom from Array, then remove from original Array

[TheGeneral2899 19]

Seems to have gotten me stuck after an hour or so of searching. 

1)  Array of 10 unit names

2)  Use Bis_fnc_selectRandom from them to choose one random of them.

3)  *ISSUE* I want to create a new array of the remaining 9 units (minus the one that was random).

 

// Array of all possible locations (items are pens for placement reasons)
_potentialLoc = [bomb1,bomb2,bomb3,bomb4,bomb5,bomb6,bomb7,bomb8,bomb9,bomb10];

// selects randomized location for bomb
_bombRandom = _potentialLoc call BIS_fnc_selectRandom;  

// gets position of randomly selected bomb
_bombLoc = getPosATL _bombRandom;

//Creates the bomb box and then the detonante script
bombActual = createVehicle ["CUP_ammobednaX", _bombLoc, [], 0, "CAN_COLLIDE"];
_disarmBomb = [bombActual] execVM "detonate.sqf";

// Create new array of remaining false bomb locations
// HERE IS MY ISSUE
_fakeBombLoc = _potentialLoc - _bombRandom;
sleep 3;
hint str _fakeBombLoc; // [1,2,3] 

When attempting to print it out, I still get the full list of 10 bomb locations despite.

 

Any help would be greatly appreciated!  Thanks!

Figured out the issue.  

 

Previous code:

_fakeBombLoc = _potentialLoc - _bombRandom;

 

Fixed code:

_fakeBombLoc = _potentialLoc - [_bombRandom];

[pierremgi 4906]

_potentialLoc = [bomb1,bomb2,bomb3,bomb4,bomb5,bomb6,bomb7,bomb8,bomb9,bomb10];

_bombRandom = _potentialLoc deleteAt (floor random count _potentialLoc);

 

now _potentialLoc returns the 9 remaining bombs.
