Delete an array selection?

[Grinher1988 10]

I made a really simple enemy convoy script but besides the A3 AI being terrible drivers theres a bigger problem a little town called "Sagonisi" is sometimes selected as a destination for the convoy and its inaccessible to land vehicles. I tried _townlist = _townlist - ["Sagonisi"]; but that doesn't seem to work can anyone help? Also a related question how can I spawn more vehicles but in a way they aren't spawned on top of the previously spawned vehicle?

TLDR; how can I blacklist/delete a selected town from an array?

//==============Enemy Convoy Script============
//place null = [] execVM "randomConvoy.sqf"; in init.sqf or whatever :P
//place an object on the map named myAmmoBox or change it on line 12
//line 33 change side west,east, or resistance
//line 36 change vehicle type
//***THIS SCRIPT LOOPS SO ONLY CALL IT ONCE!***

if (!isServer) exitWith {};//Should prevent 40+ convoy spawning on mission start 

//===========================Random time before next convoy===========================================================

_delay = 900 max (floor(random 1800));//in seconds default is 15~30mins after the first convoy spawn

//============================Create List of Towns====================================================================

_townlist = nearestLocations [getpos myAmmoBox, ["NameCityCapital","NameCity","NameVillage"],15000];//get list of towns
_townlist = _townlist - ["Sagonisi"];//Blacklist doesn't work yet :c

_rnd = floor random (count _townlist);
_townStart = _townlist select _rnd;

_roadList = (getPos _townStart) nearRoads 100;
_rndRoad = floor random (count _roadList);
_roadStart = _roadList select _rndRoad;

_townlist = _townlist - [_townStart];

_townEnd = _townlist select _rnd;

_town_Start = text (_townStart);
_town_End = text (_townEnd);

OH! I forgot that I figured out how to delete the first town picked to prevent start/end being in the same place with _townlist = _townlist - [_townStart]; but I don't understand why _townlist = _townlist - ["Sagonisi"]; does nothing!

[f2k sel 164]

_townlist = nearestLocations [getpos myAmmoBox, ["NameCityCapital","NameCity","NameVillage"],15000];

is giving you a list of grid locations not the names of the towns.

You will need to do a little work to retrieve then actual name.

_Names_of_Towns = [];
_Town_Locations = nearestLocations [position player, ["NameCityCapital","NameCity","NameVillage"], 6000];// array of locations

{
_Names_of_town = pushback classname _x;// gets the name & makes an array of town names   
} foreach _Town_Locations;

 hint str _Names_of_Towns;
// or  hint str (_Names_of_Towns - ["Agis_Marina"]);// you can now manipulate the array

Thank you F2k, I figured out a way of deleting the grid coordinates from your example. I have another question for some reason this line of code is failing but not sure why?

while {true} do
{
waitUntil{{alive _x} count units _convoyGroup < 1 or (leader _convoyGroup) distance getMarkerPos "End" < 25};
};

waitUntil is a loop itself, no need to put a while loop around it.

Thanks I finally got everything working, but because of how horrible the AI drive compared to A2 this is a waste of time.

I did think that when I saw the word Convoy.
