## 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. Be aware that the functions modify the UI, and therefore need to be executed on client-side to take effect.

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:

```cpp
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`:

```cpp
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.

### 3.1 fnc_createAction

`ace_interact_menu_fnc_createAction`

```cpp
/*
 * 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)
 */
```

### 3.2 fnc_addActionToClass

`ace_interact_menu_fnc_addActionToClass`

```cpp
/*
 * 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.

### 3.3 fnc_addActionToObject

`ace_interact_menu_fnc_addActionToObject`

```cpp
/*
 * 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>
 */
```

### 3.4 fnc_addActionToZeus

`ace_interact_menu_fnc_addActionToZeus`

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

### 3.5 Examples

External:

```cpp
_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:

```cpp
_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:

```cpp
// 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:

```cpp
_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;
```

### 3.6 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.

```cpp
_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;
```

### 3.7 Using `ace_interact_menu_newControllableObject` event

CBA event `ace_interact_menu_newControllableObject` fires only once the first time the player controls a new object (new man, vehicle or controlled UAV)
This is the ideal way to add self interaction actions, as adding them via `addActionToClass` will force self interaction actions to be compiled for classes that may never be used.

```cpp
// Example: Add radio self-action to all civilian cars
["ace_interact_menu_newControllableObject", {
    params ["_type"]; // string of the object's classname
    if (!(_type isKindOf "Car")) exitWith {};
    if ((getNumber (configFile >> "CfgVehicles" >> _type >> "side")) != 3) exitWith {};
    
    private _action = ["playRadio","Play Radio","",{playMusic "NeverGonnaGiveYouUp"},{true}] call ace_interact_menu_fnc_createAction;
    [_type, 1, ["ACE_SelfActions"], _action, true] call ace_interact_menu_fnc_addActionToClass;
}] call CBA_fnc_addEventHandler;
```
