Arma 3 introduces a module framework, which lets designer to simplify the configuration and chose how the module function will be executed (e.g., globally and for every player who joins later).
 
== How to Create a Module ==
When creating a new module, follow these steps:
<ol starts="4">
<li><big>'''Create a module addon.'''</big></li>
* Make a folder named ''<span style="color:indigo">myTag</span>_addonName'' a create a ''config.cpp'' file in it.
* Inside, declare a CfgPatches class with your addon and its modules (in the ''units'' array). Without this, the game wouldn't recognize the addon.
* Make sure the addon and all objects start with your tag, e.g. <span style="color:indigo">myTag</span>
class CfgPatches
{
class <span style="color:indigo">myTag</span>_addonName
{
units[] = {"<span style="color:indigo">myTag</span>_<span style="color:green">Module</span><span style="color:orangered;">Nuke</span>"};
requiredVersion = 1.0;
requiredAddons[] = {"A3_Modules_F"};
};
};
 
 
<li><big>'''Select a module category'''</big></li>
* Modules are placed into basic categories which makes finding a desired module easier for an user. Use can use on of the existing categories:
{| class = "wikitable"
! class
! displayName
|-
| ''Effects''
| Effects
|-
| ''Events''
| Events
|-
| ''Modes''
| Gameplay Modes
|-
| ''GroupModifiers''
| Group Modifiers
|-
| ''Intel''
| Intel
|-
| ''NO_CATEGORY''
| Misc
|-
| ''Multiplayer''
| Multiplayer
|-
| ''ObjectModifiers''
| Object Modifiers
|-
| ''Sites''
| Sites
|-
| ''StrategicMap''
| Strategic
|-
| ''Supports''
| Supports
|}
Alternatively, you can create your own one:
class CfgFactionClasses
{
class NO_CATEGORY;
class <span style="color:indigo">myTag</span>_<span style="color:teal">explosions</span>: NO_CATEGORY
{
displayName = "Explosions";
};
};
 
 
<li><big>'''Create config for module logic'''</big></li>
* All in-game objects (soldiers, vehicles, buildings, logics, modules, ...) are defined in ''CfgVehicles'' class.
* '''All modules must inherit from Module_F''' parent class, either directly or through some additional sub-parent. While modules inheriting from some other class will be still displayed in the Modules menu (F7), they won't be using the module framework and all benefits tied to it.
* Modules functions are by default <u>not</u> executed when in [[Eden Editor]] workspace. It can be enabled using ''is3DEN'' property, but that will also change format of function params (see the section about writing a function below).

* Pre-defined sync preview entities are:
** '''Anything''' - Any object - persons, vehicles, static objects, etc.
** '''AnyPerson''' - Any person. Not vehicles or static objects.
** '''AnyVehicle''' - Any vehicle. No persons or static objects.
** '''AnyStaticObject''' - Any static object. Not persons or vehicles.
** '''AnyBrain''' - Any AI or player. Not empty objects
** '''AnyAI''' - Any AI unit. Not players or empty objects
** '''AnyPlayer''' - Any player. Not AI units or empty objects
** '''EmptyDetector''' - Any trigger
 
 
<li><big>'''Configure a module function'''</big></li>
* Place '' class CfgFunctions'' to ''config.cpp''. See [[Functions Library (Arma 3)]] for more info about functions configuration.
class CfgFunctions
{
class <span style="color:indigo">myTag</span>
{
class <span style="color:teal">Effects</span>
{
file = "\<span style="color:indigo">myTag</span>_addonName\functions";
class <span style="color:green">module</span><span style="color:orangered;">Nuke</span>{};
};
};
};
 
 
<li><big>'''Write the module function</big></li>
* Create the ''functions'' folder within the addon folder and place *.sqf or *.fsm files there.
* Example: ''\<span style="color:indigo">myTag</span>_addonName\functions\fn_<span style="color:green">module</span><span style="color:orangered;">Nuke</span>.sqf''
* Input parameters differ based on value of ''is3DEN'' property.

'''Eden Editor Compatible'''
 
When ''is3DEN = 1'' is set in module config, different, more detailed params are passed to the function.

switch _mode do {

case "init": {
_logic = _input param [0,objNull,[objNull]]; {{codecomment|// Module logic}}

_isCuratorPlaced = _input param [2,false,[true]]; {{codecomment|// True if the module was placed by Zeus}}
{{codecomment|// ... code here...}}
};
{{codecomment|// When some attributes were changed (including position and rotation)}}
case "attributesChanged3DEN": {
_logic = _input param [0,objNull,[objNull]]; {{codecomment|// Module logic}}
{{codecomment|// ... code here...}}
};
{{codecomment|// When added to the world (e.g., after undoing and redoing creation)}}
case "registeredToWorld3DEN": {
_logic = _input param [0,objNull,[objNull]]; {{codecomment|// Module logic}}
{{codecomment|// ... code here...}}
};
{{codecomment|// When removed from the world (i.e., by deletion or undoing creation)}}
case "unregisteredFromWorld3DEN": {
_logic = _input param [0,objNull,[objNull]]; {{codecomment|// Module logic}}

{{codecomment|// When connection to object changes (i.e., new one is added or existing one removed)}}
case "connectionChanged3DEN": {
