Added in ACE3 v3.0.0

Interaction Menu Framework

1. Types of actions

  • External (Type 0 / ACE_Actions) Something the user would do to an external object (eg. Tap another unit’s shoulder)
  • Self (Type 1 / ACE_SelfActions) Something the user would do to themselves or to their vehicle (eg. Put in ear plugs / Check mounted Static Weapon’s ammo)
  • Zeus (ACE_ZeusActions) Available to Zeus

ACE_Actions and ACE_SelfActions can be added via config or by calling functions, it is generally preferred to add actions via config. Zeus actions can only be added via config.

The simplest action is just a condition and statement. The code to these are passed [_target, _player, _actionParams]. _player is ace_player; _target is the object being interacted with; and the 3rd argument is the optional action parameters (default []).

2. Adding actions via config

Example:

class CfgVehicles {
    class Man;
    class CAManBase: Man {
        class ACE_SelfActions {
            class danceParty {
                displayName = "dance";
                condition = "[_player] call onDanceFloor";
                exceptions[] = {};
                statement = "_player switchMove 'TestDance'";
                icon = "\z\dance.paa";
Config Name Type Description
displayName String Text shown to user
condition String (of code) Condition to show the action
statement String (of code) Statement run when selected
icon String (file path) Icon shown (OPTIONAL)
exceptions Array (of strings) Exceptions to canInteractWith conditions (e.g. "notOnMap") (OPTIONAL)
insertChildren String (of code) Code to return sub actions (OPTIONAL)
modifierFunction String (of code) Code to modify this action (OPTIONAL)
runOnHover Number or String (1=true) OR Condition code - Will run the statement on hover (OPTIONAL)
distance Number External Base Actions Only, Max distance player can be from action point
position String (of code) External Base Actions Only, Code to return a position in model cords (priority over selection)
selection String External Base Actions Only, A memory point for selectionPosition

Actions can be inserted anywhere on the config tree, e.g. hearing’s earplugs is a sub action of ACE_Equipment:

class CAManBase: Man {
    class ACE_SelfActions {
        class ACE_Equipment {
            class ACE_PutInEarplugs {

3. Adding actions via scripts

Two steps, creating an action (array) and then adding it to either a class or object. Important: ace_common_fnc_canInteractWith is not automatically checked and needs to be explicitly called.

2.1 fnc_createAction

ace_interact_menu_fnc_createAction

/*
 * Argument:
 * 0: Action name <STRING>
 * 1: Name of the action shown in the menu <STRING>
 * 2: Icon <STRING>
 * 3: Statement <CODE>
 * 4: Condition <CODE>
 * 5: Insert children code <CODE> (Optional)
 * 6: Action parameters <ANY> (Optional)
 * 7: Position (Position array, Position code or Selection Name) <ARRAY>, <CODE> or <STRING> (Optional)
 * 8: Distance <NUMBER> (Optional)
 * 9: Other parameters [showDisabled,enableInside,canCollapse,runOnHover,doNotCheckLOS] <ARRAY> (Optional)
 * 10: Modifier function <CODE> (Optional)
 */

2.2 fnc_addActionToClass

ace_interact_menu_fnc_addActionToClass

/*
 * Argument:
 * 0: TypeOf of the class <STRING>
 * 1: Type of action, 0 for actions, 1 for self-actions <NUMBER>
 * 2: Parent path of the new action <ARRAY>
 * 3: Action <ARRAY>
 * 4: Use Inheritance (Default: False) <BOOL><OPTIONAL>
 */

By default this function will not use inheritance, so actions will only be added to the specific class.

2.3 fnc_addActionToObject

ace_interact_menu_fnc_addActionToObject

/*
 * Argument:
 * 0: Object the action should be assigned to <OBJECT>
 * 1: Type of action, 0 for actions, 1 for self-actions <NUMBER>
 * 2: Parent path of the new action <ARRAY> (Example: `["ACE_SelfActions", "ACE_Equipment"]`)
 * 3: Action <ARRAY>
 */

2.4 fnc_addActionToZeus

ace_interact_menu_fnc_addActionToZeus

/*
 * Argument:
 * 0: Parent path of the new action <ARRAY> (Example: `["ACE_ZeusActions"]`)
 * 1: Action <ARRAY>
 */

2.5 Examples

External:

_action = ["VulcanPinch","Vulcan Pinch","",{_target setDamage 1;},{true},{},[parameters], [0,0,0], 100] call ace_interact_menu_fnc_createAction;
[cursorTarget, 0, ["ACE_TapShoulderRight"], _action] call ace_interact_menu_fnc_addActionToObject;

Self:

_condition = {
    (!pabst_radioFinder_on) && {(backpack _player) in pabst_radioFinder_backpacks} && {[_player, _target, []] call ace_common_fnc_canInteractWith}
};
_statement = {
    [true] call pabst_fnc_radioFinder_action;
};
_action = ["Open RDF","Radio Direction Finder","pabst\RDF.jpg",_statement,_condition] call ace_interact_menu_fnc_createAction;
[(typeOf _unit), 1, ["ACE_SelfActions"], _action] call ace_interact_menu_fnc_addActionToClass;

Using addActionToClass inheritance:

// Adds action to check fuel levels for all land vehicles
_action = ["CheckFuel", "Check Fuel", "", {hint format ["Fuel: %1", fuel _target]}, {true}] call ace_interact_menu_fnc_createAction;
["LandVehicle", 0, ["ACE_MainActions"], _action, true] call ace_interact_menu_fnc_addActionToClass;

// Adds action to check external fuel levels on tanks.  Will be a sub action of the previous action.
_action = ["CheckExtTank","Check External Tank","",{hint format ["Ext Tank: %1", 5]},{true}] call ace_interact_menu_fnc_createAction;
["Tank_F", 0, ["ACE_MainActions", "CheckFuel"], _action, true] call ace_interact_menu_fnc_addActionToClass;

Zeus:

_statement = {
    playSound3D ["alarm.ogg", theBase]
};
_action = ["myMissionEvent1","Mission Event: Play Base Alarm","",_statement,{true}] call ace_interact_menu_fnc_createAction;
[["ACE_ZeusActions"], _action] call ace_interact_menu_fnc_addActionToZeus;

2.6 Advanced Example

This adds an interaction to a unit that allows passing items that the player is carrying.

  • The child actions are generated dynamically based on the items in the player’s inventory.
  • The parent action’s display name is modified based on the item count.
  • When hovering on the action, a hint text is sent to the target.
_condition = {
    true
};
_statement = {
    params ["_target", "_player", "_params"];
    diag_log format ["_statement [%1, %2, %3]", _target, _player, _params];

    // Run on hover:
    ["ace_common_displayTextStructured", ["someone is thinking of giving you items", 1.5, _target], [_target]] call CBA_fnc_targetEvent;
};
_insertChildren = {
    params ["_target", "_player", "_params"];
    diag_log format ["_insertChildren [%1, %2, %3]", _target, _player, _params];

    // Add children to this action
    private _actions = [];
    {
        private _childStatement = {diag_log format ["givingItem %1", _this]; _target addItem (_this select 2);};
        private _action = [format ["item:%1",_x], _x, "", _childStatement, {true}, {}, _x] call ace_interact_menu_fnc_createAction;
        _actions pushBack [_action, [], _target]; // New action, it's children, and the action's target
    } forEach (items _player);

    _actions
};
_modifierFunc = {
    params ["_target", "_player", "_params", "_actionData"];
    diag_log format ["_modifierFunc [%1, %2, %3]", _target, _player, _params];

    // Modify the action - index 1 is the display name, 2 is the icon...
    _actionData set [1, format ["Give Items: %1", count (items player)]];
};

_action = ["GiveItems", "?","",_statement,_condition,_insertChildren,[123],"",4,[false, false, false, true, false], _modifierFunc] call ace_interact_menu_fnc_createAction;
[q3, 0, ["ACE_MainActions"], _action] call ace_interact_menu_fnc_addActionToObject;
