Call a function via config.cpp

[juleshuxley 9]

I want to run a function before EVERY mission. This is a QOL addon, not a scenario. I do not want the CBA dependency for something that should be so simple.

I've spent 8 hours trying to get fn_myFunction to run when a mission is started. 🙃🙃🤬

This is the structure of my mod:

This is the contents of config.cpp:

class CfgPatches{
  class SinglePlayerCharacterSwitcher{
    author = "CaptainDucko";
    version = 1.0;
    units[]={};
    weapons[]={};
    requiredAddons[]={};
    requiredVersion = 0.1;
  };
};

class CfgFunctions
{
    class myTag
    {
        class myCategory
        {
            class myFunction {};
        };
    };
};

This is the result:

🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬
WHY IT'S RIGHT HERE

Sorry but 8 hours trying backslashes, forward slashes, changing directory structures, building, building, building I'm going insane.

dude my screenshots depict the example shown under "Default Path (Mission Only)". I've tried every example and nothing works I have no idea what I'm missing

[juleshuxley 9]

Second example from that page just just does not work!!!!
Structure:

Config:

class CfgPatches{
  class SinglePlayerCharacterSwitcher{
    author = "CaptainDucko";
    version = 1.0;
    units[]={};
    weapons[]={}; 
    requiredAddons[]={};
    requiredVersion = 0.1;
  };
};

class CfgFunctions
{
	class myTag
	{
		class myCategory
		{
			class myFunction {file = "myFile.sqf";};
		};
	};
};

ERROR: 😡

This will try to compile function myTag_fnc_myFunction from the following file:

%ROOT%\myFile.sqf

Are you calling the function as in bold statement?

i.e.:

call myTag_fnc_myFunction;

[juleshuxley 9]

I'm writing `call myTag_fnc_myFunction` in the console. But I get the Script myFile.sqf not found error when I start up Arma, before I start a mission / scenario in the editor

[RCA3 593]

But the function works?

All I can say is add this to requiredAddons, if the function works and this doesn't help I don't know.

requiredAddons[]={"A3_Data_F_Enoch_Loadorder"};

Wait... what is this? Remove that. Nevermind it's your addon name 😑

Try giving it a name

name = "Your mod name";

And not sure version should be there.

The function not working, might be an error on the function. Debug it to RPT first with just one command. diag_log

[juleshuxley 9]

No the fuction doesn't work, I'll trt that requiredAddons, thank you

[juleshuxley 9]

Doesn't work.  ridiculous. such weak documentation. ive tried every example on that page. thanks for trying though

[RCA3 593]

You need to pass your addon folder name first:

class myFunction {file = "SinglePlayerCharacterSwitcher\myFile.sqf";};

[juleshuxley 9]

Here is the structure of my project. It contains just two files, config.cpp and myFile.sqf:

config.cpp:

class CfgPatches{
  class Test{
    author = "CaptainDucko";
    name = "S P C S";
    units[]={};
    weapons[]={}; 
    requiredAddons[]={"A3_Data_F_Enoch_Loadorder"};
    requiredVersion = 0.1;
  };
};

class CfgFunctions
{
	class myTag
	{
		class myCategory
		{
			class myFunction {file = "\myFile.sqf";};
		};
	};
};

myFile.cpp:

myTag_fnc_myFunction = {
	_returnThis = "doesnt_work";
	_returnThis;
};

When I start Arma 3, I get this error:


Why? I have changed the file attribute to "file = myFile.sqf" and "file = /myFile.sqf" but I get the same error message every time.

[RCA3 593]

Read above.

This case would be:

class myFunction {file = "test\myFile.sqf";};

Btw works both with "\test\..." or "test\..."

};

 

I think you mean myfile.sqf and that's not how it works.

You don't redefine the function inside the file, it's already defined at this point.

 Just type the commands you want to call immediately. As a test use this:

 

myfile.sqf:

systemChat "hello";

 

And your folder organization should be:

@test-master\addons\test\

Try this just replace "modFolderName" with the name of the folder your mod is in. To call the function you would use [] call fnc_myFunction; if calling from another file or SQF but the preInit will launch the script when the mod gets loaded in.

class CfgPatches{
  class SinglePlayerCharacterSwitcher{
    author = "CaptainDucko";
    version = 1.0;
    units[]={};
    weapons[]={};
    requiredAddons[]={};
    requiredVersion = 0.1;
  };
};

class CfgFunctions
{
    class myCategory {
        file = "modFolderName\myCategory"; 
        class myFunction{
            preInit = 1;
        };
    };
};

};

 

Where is the reference to myFile.sqf . And what's myCategory?

[juleshuxley 9]

this is so dumb. I've created a really complicated mod, but it's in script form for one of my eden projects. I've done the hard bit. It works. Now I just need to package it into a addon and have an initialization function fire on mission start. That's it. Insane. Day wasted. In a C++ project, init.cpp is always run first. In a website, index.html is opened first. In Arma 3?!?! god only knows how you create an init script.

I forgot you got to call myTag_fnc_myFunction on debug console.

Try my code in your original post format. "myCatergory" is the folder and "myFunction" is the filename. If a file is named "fn_myFunction.sqf" then arma will know to make that file a function. Paste my code into your config.cpp file and it should work.

Thank you for your example it was invaluable. This stuff is simple but very fiddly for a beginner imho. Thankyou maihym. My mod is working!!

xD it's been a while since I've worked with Arma 3 but it's nice to know that I've still got it
