Using functions inside a script?

Hi,

probably a stupid question. I'm trying to make my unit-equipment-setup-scripts a little more efficient. My script looks like this:

unit1 call setupLeader;
unit2 call setupRifleman;
unit3 call setupMachingunner;
exitWith{};

setupLeader = {//do all the setupcode for Leader};
setupRifleman = {//do all the setupcode for Rifleman};
setupMachingunner = {//do all the setupcode for MG};

What it does, is that unit1 ends up with the MG-equipment and unit2 and unit3 are untouched.

What is my basic problem here?

Jens

You did it the wrong way round. You need to initialize the functions first and THEN call them:

setupLeader = {//do all the setupcode for Leader};
setupRifleman = {//do all the setupcode for Rifleman};
setupMachingunner = {//do all the setupcode for MG};

unit1 call setupLeader;
unit2 call setupRifleman;
unit3 call setupMachingunner;

I tried that, but goit the same result. Here's the actual code:

exitWith{}; is not a command on its own, it is a part of the construct if () exitWith {};

As a rule of thumb, if you don't know what it does - don't use it.

Life would be boring and discoveries wouldn't happen.

Just imagine the face of the first person ever to eat a Jalapeño.

On the other hand to improve performance it's good practice to put functions into the description.ext, gives various benefits.

Well, it is not like sqf is growing on a tree. There is biki which covers 99% of all commands with 95% of sensible explanation.

Honestly, I still don't get what the difference between a function library and a global variable function is as you can get both from the missionNamespace by their name.

It would help this guy to tell him what to do rather than argue about other things ^.^

If you know how to help this guy, please do, because there is nothing wrong with his code apart from last exitwith{} which would obviously produce an error he cannot see because he probably has no error reporting enabled.

Isn't it useless to exit the script yourself at the end of the code since the script will destory itself once it has no more code to read?

That's what KK discribed twice already, including that exitWith requires an if-statement to not produce an error. ^_^

Oh wow, that's a huge wall which is easy to avoid when using a simple BIS function.

instead of:

   _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addMagazine "30rnd_556x45_STANAG";
       _this addWeapon "RH_m16a4";
       _this addMagazine "RH_15Rnd_9x19_M9";
       _this addMagazine "RH_15Rnd_9x19_M9";
       _this addMagazine "RH_15Rnd_9x19_M9";
       _this addMagazine "RH_15Rnd_9x19_M9";
       _this addWeapon "RH_m9";

you could use an easier to read version like this:

[_this,"RH_m16a4",10] call BIS_fnc_addWeapon;
[_this,"RH_m9",4] call BIS_fnc_addWeapon;

How's two lines instead of 16?

Thanks for your input guys. I did a lot of reading on those functions that already come along with ArmA. Even as I can make my setup scripts much smarter with those functions, I'm still interested in solving my original problem.

What I want to do, is to define a function in a script and use it in the same script. 

setupFT_Leader ={
   [_this,"RH_m16a4",10] call BIS_fnc_addWeapon;
   [_this,"RH_m9",4] call BIS_fnc_addWeapon;
   };

setupFT_Grenadier ={
   [_this,"RH_m16a4gl",10] call BIS_fnc_addWeapon;
   };

setupFT_Automatic_Rifleman ={
   [_this,"LMG_mas_M249_F_a",10] call BIS_fnc_addWeapon;
   };

setupFT_Rifleman ={
   [_this,"RH_m16a4",5] call BIS_fnc_addWeapon;
   };

FT1_1_Leader call setupFT_Leader;
FT1_1_Grenadier call setupFT_Grenadier;
FT1_1_Automatic_Rifleman call setupFT_Automatic_Rifleman;
FT1_1_Rifleman call setupFT_Rifleman;

Running this code, I get the following in the RPT file:

12:42:33 Error in expression <//FT1_1_Rifleman call setupFT_Rifleman;>
12:42:33   Error position: <//FT1_1_Rifleman call setupFT_Rifleman;>
12:42:33   Error Invalid number in expression
12:42:33 Error in expression <FT1_1_Leader call setupFT_Leader;>
12:42:33   Error position: <setupFT_Leader;>
12:42:33   Error Undefined variable in expression: setupft_leader
12:42:33 Error in expression <FT1_1_Grenadier call setupFT_Grenadier;>
12:42:33   Error position: <setupFT_Grenadier;>
12:42:33   Error Undefined variable in expression: setupft_grenadier
12:42:33 Error in expression <FT1_1_Automatic_Rifleman call setupFT_Automatic_Rifleman;>
12:42:33   Error position: <setupFT_Automatic_Rifleman;>
12:42:33   Error Undefined variable in expression: setupft_automatic_rifleman

Just because it was never asked, but just to be certain, are you execVM this script?

Replace

FT1_1_Grenadier call setupFT_Grenadier;
FT1_1_Automatic_Rifleman call setupFT_Automatic_Rifleman;
FT1_1_Rifleman call setupFT_Rifleman;

with

NO!! I only used "exec" and not "execVM"!! That did the trick. Thanks mate. No it works as it is supposed to be.

Those functions should be local variables not global variables if they are only used in that script.

You have, which are global variables:

setupLeader = {};
setupRifleman = {};
setupMachingunner = {};

You can use instead; these functions will only be local to this script:

_setupLeader = {};
_setupRifleman = {};
_setupMachingunner = {};

So put an underscore in front of those function variables if they are only needed in that one script.

edit: nevermind I didn't see that you actually do want the functions global because your using 'bis_fnc_mp'. You said in the title functions inside scripts. So I interpreted it as you wanting local functions.
