ACE Arsenal Framework (2023)

Added in ACE3 v3.12.0

BI functions and variables from BI Virtual Arsenal DO NOT apply to ACE Arsenal!

Units and objects that can have ACE Arsenal added to them will be called "Boxes" in this documentation.

To quickly add a full ACE Arsenal to a box for all clients use the following code:

[_box, true] call ace_arsenal_fnc_initBox;

_box being the object you wish to add ACE Arsenal to (or this when called from the box’s init field).

1. Access to ACE Arsenal

1.1 Adding ACE Arsenal to a box


Argument Type Optional (default value)
0 Box Object Required
1 Items Array of strings or boolean Required
2 Initialize globally Boolean Optional (default: false)

This will add the virtual items passed as arguments and add an ACE interaction to open ACE Arsenal.

  • [_box, ["MyItem1", "MyItem2", "MyItemN"]] call ace_arsenal_fnc_initBox
  • [_box, true] call ace_arsenal_fnc_initBox
  • [_box, false, false] call ace_arsenal_fnc_initBox

Passing an empty array or false will still add an interaction but no additional virtual items will be added.
Please note that at least one virtual item needs to be added otherwise ACE Arsenal will not open.

1.2 Opening an arsenal box manually


Argument Type Optional (default value)
0 Box Object Required
1 Unit to open ACE Arsenal on Object Required
2 Ignore virtual items and fill ACE Arsenal Boolean Optional (default: false)


  • [_box, player] call ace_arsenal_fnc_openBox
  • [player, player, true] call ace_arsenal_fnc_openBox

In the second example a full ACE Arsenal will be opened on the player.

1.3 Removing the ACE Arsenal interaction


Argument Type Optional (default value)
0 Box Object Required
2 Remove globally Boolean Optional (default: false)

Example: [_box, true] call ace_arsenal_fnc_removeBox

2. Virtual items

2.1 Adding virtual items


Argument Type Optional (default value)
0 Box Object Required
1 Items Array of strings or boolean Required
2 Add globally Boolean Optional (default: false)

Passing an array of strings (class names) will add each one of those items to the specified box, passing true will add ALL items that are compatible with ACE Arsenal (the sorting is done on game startup).


  • [_box, ["item1", "item2", "itemN"]] call ace_arsenal_fnc_addVirtualItems
  • [_box, true, false] call ace_arsenal_fnc_addVirtualItems

2.2 Removing virtual items


Argument Type Optional (default value)
0 Box Object Required
1 Items Array of strings or boolean Required
2 Remove globally Boolean Optional (default: false)

Like adding virtual items, passing an array of string (class names) will remove each ones of those items, however passing true will remove all virtual items and also remove the interaction to access ACE Arsenal.

  • [_box, ["item1", "item2", "itemN"]] call ace_arsenal_fnc_removeVirtualItems
  • [_box, true, false] call ace_arsenal_fnc_removeVirtualItems

2.3 Arsenal only with items from default loadouts (See section 4)

Built upon the function of section 2.1, this can be used to make an Arsenal only with the items from your precreated loadouts. This is the best choice if you do not want to make a full arsenal available to have your loadouts spawnable.

  1. Spawn the same amount of units as you have loadouts, give each unit one of them
  2. Start the mission then press ESC once loaded
  3. Clear the debug console then enter the following:
    private _items = flatten (allUnits apply {getUnitLoadout _x});_items = _items arrayIntersect _items select {_x isEqualType "" && {_x != ""}};copyToClipboard str _items;
  4. Paste the created array from your clipboard into the space where the items are listed using Ctrl + V. The array is created with brackets.


  • For a new box:
    [_box, ["item1", "item2", "itemN"]] call ace_arsenal_fnc_initBox
  • For an existing box:
    [_box, ["item1", "item2", "itemN"]] call ace_arsenal_fnc_addVirtualItems

3. Config entries

ACE Arsenal has 2 new config entries for items:

  • ace_arsenal_hide: 0(shown) or 1 (hidden), used to hide items from ACE Arsenal or -1 (forced show), for vehicle magazines.
  • ace_arsenal_uniqueBase: Class name of the item that ACE Arsenal will replace it with when saving a loadout.

Both of them are optional.

4. Default loadouts

4.1 Adding default loadouts via 3DEN

While in 3DEN you have the ability to save default loadouts in ACE Arsenal, doing so will make the saved loadouts available to all players (those loadouts are still subject to loadout verification). To do so:

  • Open ACE Arsenal in 3DEN by editing a unit’s loadout.
  • Click on the “Loadouts” tab.
  • Click on the “Default Loadouts” tab.
  • Enter a loadout name and save.

This loadout list can be exported to the clipboard by using Shift + LMB. on the export button, doing the same on the import button will import the list currently in the clipboard.

4.2 Adding default loadouts via script


Argument Type Optional (default value)
0 Name of loadout String Required
1 getUnitLoadout array Array Required

Example: ["Squad Leader", getUnitLoadout sql1] call ace_arsenal_fnc_addDefaultLoadout

If a loadout with the same name exists, it will be overwritten.

5. Stats

ACE Arsenal stats are customizable, this will show you how.

5.1 Adding stats via config

class ace_arsenal_stats { class statBase; class TAG_myStat: statBase { scope = 2; // Only scope 2 show up in arsenal, scope 1 is used for base classes. displayName = "Test entry title"; // Title of the stat. priority = 0; // A higher value means the stat will be displayed higher on the page. stats[] = {"mySuperStat"}; // Array of strings to pass to the statements, typically showBar = 1; // 0 disabled; 1 enabled; showText = 1; // 0 disabled; 1 enabled; barStatement = "1"; // Statement evaluated to set the bar progress, needs to return a NUMBER. textStatement = "test entry"; // statement evaluated to set the text entry, can return anything. condition = "true"; // Condition for the stats to be displayed, default is true if not defined, needs to return a BOOL. tabs[] = { {0,1,2}, { } }; // Arrays of tabs, left array is left tabs, right array is right tabs. };};

The arguments passed to the bar, text and condition statements are:

  • The stats array <ARRAY of STRINGS>
  • The config entry of the weapon <CONFIG>

5.2 Adding stats via a function


Argument Type Optional (default value)
0 Tabs to add the stat to Array of arrays Required
0.1 Left tab indexes Array of numbers Required
0.2 Right tab indexes Array of numbers Required
1 Stat class ID String Required
2 Config entries to pass Array of strings Required
3 Title String Required
4 Show bar / show text bools Array of booleans Required
4.1 Show bar Boolean Required
4.2 Show text Boolean Required
5 Array of statements Array of arrays Required
5.1 Bar code Code Required
5.2 Text code Code Required
5.3 Condition Code Required
6 Priority Number Optional (default: 0)


[[[0,1,2], [7]], "scopeStat", ["scope"], "Scope", [false, true], [{}, { params ["_statsArray", "_itemCfg"]; getNumber (_itemCfg >> _statsArray select 0)}, {true}]] call ACE_arsenal_fnc_addStat;

5.3 Removing stats via a function


Argument Type Optional (default value)
0 Array of IDs Array Required

Stats IDs are unique, IDs are generated as follows:

Class + side + tab

For example: testClassL03

  • Class: testClass
  • Side: L for the left panel
  • Tab: 03 for the 3rd tab

For config added stats the classname is used, for function added ones the string provided is used.
