Can't get functions to work

[Luft08 27]

I've watched several videos and read many posts about functions but I can't seem to get mine to work.

description.ext:

class CfgFunctions {
	#include "functions\cfgFunctions.hpp"
};

cfgFunctions.hpp (inside a folder called functions):

class cfgFunctions {
	class LFT {
		tag = "LFT";
		class functions {
			file = "functions\functions.sqf";
			class GetDistance {};		
		};
	};
};

functions.sqf (inside the folder called functions):

GetDistance = {
	params ["_object1", "_object2"];

	private _distance = _object1 distance _object2;

	_distance
};

inside the calling script:

	private _distance = [officer_01, weaponsCache] call getDistance;
	hint str _distance;	

The officer_01 and weaponsCache are both objects. When called I get an "undefined variable getDistance" error. I've tried calling LFT_getDistance, LFT_fn_getDistance and LFT_fnc_getDistance but no joy. 

 

I need a slow thinker's tutorial I guess. 😞

Description.ext

class CfgFunctions {
	#include "functions\cfgFunctions.hpp"
};

functions\cfgFunctions.hpp

class LFT { //Project
	tag = "LFT"; //TAG
	class functions { //Category
		file = "functions"; //Folder path the following functions are found in
		class GetDistance {}; //function .sqf file name, minus proceeding fn_	
	};
};

functions\fn_GetDistance.sqf

params ["_object1", "_object2"];

//Last evaluation is the returned value
_object1 distance _object2

Produces the function LFT_fnc_GetDistance ( TAG_fnc_fileName )

hint str ( [officer_01, weaponsCache] call LFT_fnc_getDistance );

Project and Category can be used in the functions viewer drop downs to see your functions.

Perfect! With this example I think I may be able to write functions.

 

There is one thing. The editor I use gives a warning on the hint line: 

"Public variable 'LFT_fnc_getDistance' may be used before being assigned a value."

 

The mission does not complain at all but am I forgetting to define the function or something (Just to shut my editor up)

Ignore the warning. Functions defined by CfgFunctions, are compiled final before anything else is run( init, intPlayer, initServer etc )
