ArmA 3

Introduction

I have been playing Operation: Flashpoint and its Resistance expansion back in the day, started scripting things for it and made a ton of scenarios and a larger bunch of scripts. I've played the SP campaign of ArmA. I started playing ArmA 2 and its expansions mid-2010, after which I got the taste of scripting and making scenarios again. Safe to say I've spent many nights scripting SQF in the RV engine.

Over time I've collected a bunch of notes and scripts I've used to create my scenarios. It would be selfish to keep them for myself, so here are they. I've tried to sort them on version (ArmA 2 and ArmA 3) and mod (just ACE2).

General SQF

The following examples should work in both ArmA 2and ArmA 3.

Everything about groups

Create a new group

_grp = group this

Moving all units of a group into a vehicle

{_x moveincargo taxi} foreach units group this

Check if a group is inside a vehicle

({_x in taxi} count units grp1) == (count units grp1)

Check if a group is not inside a vehicle

{_x in taxi} count (units grp1) ==  0

Check to see if all playable west units are in a trigger area

{alive _x && side _x == WEST && vehicle _x in thislist} count allunits == {alive _x && side _x == WEST} count allunits

Start a script that is part of a mod (requires CBA)

Put in config.cpp:

class CfgPatches {
    class gfs {
        units[] = {};
        weapons[] = {};
        requiredVersion = 1.00;
        requiredAddons[] = {"CBA_MAIN"};
        author[] = {"Sacha Ligthert"};
        versionDesc = "This latest version";
        version = "0.29";
    };
};
class Extended_PreInit_EventHandlers    {
    class gfs    {
        init = "[] execVM 'folder\init.sqf';";
};

Mute in-game radio commands

0 fadeRadio 0;  //mute in-game radio commands

Removing the Respawn Button

private["_display","_btnRespawn"];

disableSerialization;
waitUntil {
    _display = findDisplay 49;
    !isNull _display;
};

_btnRespawn = _display displayCtrl 1010;
_btnRespawn ctrlEnable false;

Detect a JIP

if (!(isNull player)) then  //non-JIP player
{

};

if (!isServer && isNull player) then  //JIP player
{

};

Count the building positions

x = 0;
while { format ["%1", house buildingPos x] != "[0,0,0]" } do {x = x + 1};
hint format ["%2: 0 - %1", x-1, "Available positions"];

Locations and Buildings

Find all in the cities

SL_fnc_urbanAreas = {
    private ["_locations","_cityTypes","_randomLoc","_x","_i","_cities"];
    _i = 0;
    _cities = [];

    _locations = configfile >> "CfgWorlds" >> worldName >> "Names";
    _cityTypes = ["NameVillage","NameCity","NameCityCapital"];

    for "_x" from 0 to (count _locations - 1) do {
        _randomLoc = _locations select _x;
        // get city info
        _cityName = getText(_randomLoc >> "name");
        _cityPos = getArray(_randomLoc >> "position");
        _cityRadA = getNumber(_randomLoc >> "radiusA");
        _cityRadB = getNumber(_randomLoc >> "radiusB");
        _cityType = getText(_randomLoc >> "type");
        _cityAngle = getNumber(_randomLoc >> "angle");
        if (_cityType in _cityTypes) then {
            _cities set [_i,[_cityName, _cityPos, _cityRadA, _cityRadB, _cityType, _cityAngle]];
            _i = _i + 1;
        };
    };
    _cities;
};

Find all the buildings in a give area...

SL_fnc_findBuildings = {
    private ["_center","_radius","_buildings"];
    _center = _this select 0;
    _radius = _this select 1;
    _buildings = nearestObjects [_center, ["house"], _radius];
    _buildings;
};

ACRE

[0] call acre_api_fnc_setLossModelScale;

Retransmit script

Source http://www.tacticalgamer.com/script-bin/176053-script-acre-retransmit-script.html

//Retransmit on Position + Altitude

private ["_obj","_pos"];
_obj = _this;
_pos = getPosATL _obj;
[[_pos select 0, _pos select 1, (_pos select 2) + 4500], 51.850, 54.500, 20000] call acre_api_fnc_createRxmtStatic;

Segment the radio frequencies per faction

if (!isDedicated) then {

  if (isNull player) then {
    waitUntil {!isNull player};
  };

    #define FREQ_BASE 30
    _freqs = [];
    if (side player == WEST) then {
        for "_i" from 0 to 99 do {
            _freq = FREQ_BASE + (_i * 3) + 0.500;
            _freqs = _freqs + [_freq];
        };
    } else {
        for "_i" from 0 to 99 do {
            _freq = FREQ_BASE + (_i * 3) + 1.250;
            _freqs = _freqs + [_freq];
        };
    };
    ["ACRE_PRC148", _freqs] call acre_api_fnc_setDefaultChannels;
    ["ACRE_PRC117F", _freqs] call acre_api_fnc_setDefaultChannels;
    ["ACE_P159_RD99", _freqs] call acre_api_fnc_setDefaultChannels;


    #define FREQ_BASE 2400
    _freqs = [];
    if (side player == WEST) then {
        for "_i" from 0 to 99 do {
            _freq = FREQ_BASE + _i + 0.200;
            //_freqs = _freqs + _freq, 50;
            _freqs = _freqs + [_freq];
        };
    } else {
        for "_i" from 0 to 99 do {
            _freq = FREQ_BASE + _i + 0.600;
            //_freqs = _freqs + _freq, 50;
            _freqs = _freqs + [_freq];
        };
    };;
    ["ACRE_PRC343", _freqs] call acre_api_fnc_setDefaultChannels;
};

_earplugs = {
    if ( ((getText(__check) == "") || (getText(__check) != (name player))) && isMultiplayer ) then {  
           // indentity incorrect
           // don't wait
    } else { // wait for init
            waitUntil { sleep 0.5; _earplugs = player getVariable "ace_sys_goggles_earplugs"; !isNil "_earplugs" };
    };

Storing stuff in databases

ALiVE_fnc_getHash

ALiVE_fnc_setHash

ligthert [6:56 PM]    @highhead: Do you happen to know something about the _getHash and _setHash functions?
highhead [6:57 PM]    its a wrapper for the CBA fncs
highhead [6:57 PM]    what do you need
highhead [6:58 PM]    actually they set and get data to arrays that look like ["CBA_HASH",_key,_value,_defaultValue]
highhead [6:58 PM]    HashGet allows you to return custom defaultvalues
ligthert [7:01 PM]    The reason I am asking is because I found out that despite persistence's best efforts some vehicles and objects (and objectives) don't stay dead after loading the scenario again. I was thinking of putting all these objectives and objects in an array and have the stored in the database. Basically abusing _setHash and _getHash as a  glorified database abstraction layer to counteract this problem. :simple_smile:
highhead [7:01 PM]    so you can basically store ANY data easily by....
_myDataHandler = [] call ALiVE_fnc_HashCreate;
[_myDataHandler,"age",36] call ALiVE_fnc_HashSet;
[_myDataHandler,"size",185] call ALiVE_fnc_HashSet;
[_myDataHandler,"eyes","blue"] call ALiVE_fnc_HashSet;
[_myDataHandler,"gay",false] call ALiVE_fnc_HashSet;
[_myDataHandler,"body",objNull] call ALiVE_fnc_HashSet;
you can then get the data with:
_age = [_myDataHandler,"age",100] call ALiVE_fnc_HashGet;
etc....
ligthert [7:02 PM]    but but but, in the last example you put down _100_, won't this fudge the value you get from hashGet up?
ligthert [7:02 PM]    Or is this de default value?
highhead [7:03 PM]    if the the age data within _myDataHandler would be not existing it would return 100
highhead [7:03 PM]    default value
ligthert [7:05 PM]    I see. :simple_smile:
ligthert [7:05 PM]    Are these hashes in a _namespace_ of the scenario or can I steal other people's hashes? :simple_smile:
Pause OPCOM when the last player disconnected
In the initServer.sqf:
["someId", "onPlayerConnected", { if (({isPlayer _x} count playableUnits) > 0 || OPCOM_TOGGLE) then { ["ALIVE_MIL_OPCOM"] call ALiVE_fnc_unPauseModule; OPCOM_TOGGLE = false; };}] call BIS_fnc_addStackedEventHandler;
["someId", "onPlayerDisconnected", { if ( ({isPlayer _x} count playableUnits) == 0 ) then { ["ALIVE_MIL_OPCOM"] call ALiVE_fnc_pauseModule; OPCOM_TOGGLE = true; };}] call BIS_fnc_addStackedEventHandler;
Putting crates into objects
[ALiVE_SYS_LOGISTICS,"fillContainer",[_vehicle,_payload]] call ALiVE_fnc_Logistics;
_payload is an array with class-names or objects

Opening stuff from addAction

    this addAction ["Operations", {["OPEN_OPS",[]] call ALIVE_fnc_SCOMTabletOnAction}];
    this addAction ["Intel", {["OPEN_INTEL",[]] call ALIVE_fnc_SCOMTabletOnAction}];
    this addAction ["Logistics", {["OPEN",[]] call ALIVE_fnc_PRTabletOnAction}];
    this addAction ["Tasking", {[] call ALiVE_fnc_C2MenuDef}];
    this addAction ["Combat Support", {["radio"] call ALIVE_fnc_radioAction}];

Adding custom CQB zones

    highhead [6:22 PM] Set up CQB as you would normally.
    highhead [6:23 PM] In Init.sqf put: [ALiVE_mil_CQB getVariable ["instances",[]]] call ALiVE_fnc_resetCQB;
    highhead [6:23 PM] then activate your zones with: [_pos,_radius,_CQB] spawn ALiVE_fnc_addCQBpositions.
    highhead [6:24 PM]whereas _CQB are instances of CQB modules. So the missionmaker f.e. can give it a name in editor, f.e. "CQB_regular" or "CQB_strategic" and
    highhead [6:24 PM]put it in like [_pos,_radius,[CQB_Regular]] spawn ALiVE_fnc_addCQBpositions. (edited)
    highhead [6:42 PM]  f.e. A mission maker wants to have CQB in all strategic positions over the map from the beginning of the mission. Regular CQB in a specific location should be activated by trigger.
    - Add a CQB module on setting strategic and your other favorite settings (f.e. dominantFaction, density etc.).
    - Add a CQB module on setting regular and your other favorite settings (f.e. dominantFaction, density etc.).
    - Give the regular CQB module a name, f.e. myRegularCQBmodule
    put in init.sqf
    myRegularCQBmodule call ALiVE_fnc_resetCQB;
    In your trigger activation put:
    [_pos,_radius,[myRegularCQBmodule]] spawn ALiVE_fnc_addCQBpositions.
    You can also use position thisTrigger and triggerSize variables of the trigger. Just make sure it only fires once :simple_smile:
    highhead [6:44 PM] Additionally you can use [_pos,_radius,[CQB_Regular]] spawn ALiVE_fnc_removeCQBpositions to remove active CQB areas.

Hazey and I discuss our efforts:

    [16:11:38] Sacha Ligthert: Haze, Am I the only one with the impression that our version of insurgency kickstarted groups into adopting alive?
    [16:14:00] Haze: I have seen a few larger groups run alive because of it. Would be interesting to get a download stat from tup when he is around.
    [16:16:22] Sacha Ligthert: Haze, we rock! :D
