adding +1 to a variable multiple times then counting not working

[qbt 10]

I changed the group names to the names of the groups I'm using

so scud1, scud2, scud3, scud4, scud5

all the group names are defined in the scripts that spawns each of them and they work because the final trigger checks the number of alive units is 0 for each of those groups then gives a task completed hint.

But if it works for you I must be doing something wrong.

The script could be easily implemented in to the SCUD-spawning code. Do you mind if I have a look at it? The problem is that the forEach is trying to loop trough undefined variables, since the SCUD's or their groups have not spawned yet.

Ahh right. Yes well there are 2 scripts, the one that actually makes everything work then the one that you select the vehicle/group of vehicles with and set parameters for them.

Here is the main script (VehPatrol_fnc.sqf):

There is also this line in the init.sqf which calls the main script at the start:

call compile preprocessfile "VehPatrol_fnc.sqf";

You can get it working by doing the following in init.sqf:

1)

[color=#333333]call compile preprocessFile "VehPatrol_fnc.sqf";[/color]

2)

{[color=#333333]call compile [/color][color=#333333]preprocessFile _x[/color][color=#333333]} forEach ["[/color][color=#333333]scud1.sqf", [/color][color=#333333]"[/color][color=#333333]scud2.sqf", [/color][color=#333333]"[/color][color=#333333]scud3.sqf", [/color][color=#333333]"[/color][color=#333333]scud4.sqf", [/color][color=#333333]"[/color][color=#333333]scud5.sqf"];[/color]

3)

if (isServer) then {
   vehicles_destroyed = 0;
   publicVariable "vehicles_destroyed";


   {
       if ((count (units _x)) == 1) then {
           (vehicle (leader _x)) addEventHandler ["Killed", 
               {
                   vehicles_destroyed = vehicles_destroyed + 1;
                   publicVariable "vehicles_destroyed";


                   hint format ["Vehicle destroyed, %1 vehicles remaining.", (5 - vehicles_destroyed)];
               }
           ];
       };
   } forEach [grpOne, grpTwo, grpThree];
};


waitUntil {!(isNil "vehicles_destroyed")};
"vehicles_destroyed" addPublicVariableEventHandler {
   hint format ["Vehicle destroyed, %1 vehicles remaining.", (5 - vehicles_destroyed)];
};

Edit:

Step one and two you might want to only run on the server like so:

if (isServer) then {
   call compile preprocessFile "VehPatrol_fnc.sqf";
   {call compile preprocessFile _x} forEach ["scud1.sqf", "scud2.sqf", "scud3.sqf", "scud4.sqf", "scud5.sqf"];
};

And then add rest of the code.

Ok it's working now but there's a problem, all the scuds spawn when the mission starts but I want them to spawn through a script when a blufor trigger is activated.

e.g.

Blufor present

condition: this

onAct: null = [this] execVM "scudspawns.sqf":

nul = [this] execVM "scud1.sqf";
sleep 10;
nul = [this] execVM "scud2.sqf";
sleep 10;
nul = [this] execVM "scud3.sqf";
sleep 10;
nul = [this] execVM "scud4.sqf";
sleep 10;
nul = [this] execVM "scud5.sqf";

No problem!

init.sqf

   vehicles_destroyed = 0;
   publicVariable "vehicles_destroyed";
};


waitUntil {!(isNil "vehicles_destroyed")};
"vehicles_destroyed" addPublicVariableEventHandler {
   hint format ["Vehicle destroyed, %1 vehicles remaining.", (5 - vehicles_destroyed)];
};

scudspawns.sqf

{
   call compile preprocessFile _x; sleep 10
} forEach ["scud1.sqf", "scud2.sqf", "scud3.sqf", "scud4.sqf", "scud5.sqf"];


{
   (vehicle (leader _x)) addEventHandler ["Killed", 
       {
           vehicles_destroyed = vehicles_destroyed + 1;
           publicVariable "vehicles_destroyed";

           hint format ["Vehicle destroyed, %1 vehicles remaining.", (5 - vehicles_destroyed)];
       }
   ];
} forEach [scud1, scud2, scud3, scud4, scud5];

Updated script.

[clydefrog 3]

Now it's not working again, a hint comes up at the mission start saying "vehicle destroyed, 5 vehicles remaining" and then no hints come up when I actually destroy the vehicles, I don't really want to take any more of your time over this though.

I made too many iterations and got confused myself. I updated the script in my last post, it should work now!
