Initialization

Paths

Editor:

Modules (F7) > Function Library

Data:

ca\modules\functions
ca\modules_e\functions
ca\modules_pmc\functions

Startup

Place Function manager on map. No additional synchronizing needed.

Usage

First, you need to check if Functions were already initialized:

waituntil {!isnil "bis_fnc_init"};

⚠

Always check for 'BIS_fnc_init', not specific functions (e.g. 'BIS_fnc_setpitchbank')! Never set value of 'BIS_fnc_init' in any part of mission! It may lead to breakdown of some modules!

After that, you can call any function using following syntax:

_fnc = [params] call TAG_fnc_functionName.

Adding new functions

List of functions is defined in config - CfgFunctions. New ones can be also added in Description.ext file of mission or campaign.

class cfgFunctions
{
	class BIS
	{
		class category1
		{
			class Test1 		{description="Testing file 1"};
		};
	};
	class CSLA
	{
		class category1
		{
			class Test2 		{description="Testing file 2"; file="test.sqf"};
		};
	};
};

If 'file' path is not set, system will search for file 'functions\category\fn_function.sqf" (if function is defined in description.ext) or 'ca\modules\functions\category\fn_function.sqf" (if function is in config.cpp).

Result is:

• BIS_fnc_Test1 - will load script \functions\category1\test1.sqf from mission or campaign directory
• CSLA_fnc_Test2 - will load script test.sqf
