1. Config Values

1.1 Preparing a vehicle for ACE3 cargo

class CfgVehicles {
    class yourVehicleBaseClass {
        ace_cargo_space = 4;  // Cargo space your vehicle has
        ace_cargo_hasCargo = 1;  // Enables cargo to be loaded inside the vehicle (1-yes, 0-no)
    };
};

1.2 Making an object loadable

class staticBananaLauncher {
    class yourVehicleBaseClass {
        ace_cargo_size = 4;  // Cargo space the object takes
        ace_cargo_canLoad = 1;  // Enables the object to be loaded (1-yes, 0-no)
    };
};

Note:

ace_cargo_hasCargo and ace_cargo_canLoad are only needed if you aren't inheriting from any of BI base classes or if you are trying to disable loading for a specific vehicle / object.

2. Events

2.1 Listenable

Event Name	Passed Parameter(s)	Locality	Description
ace_cargoLoaded	[_item, _vehicle]	Global	Cargo has been Loaded into vehicle
ace_cargoUnloaded	[_item, _vehicle]	Global	Cargo has been Unloaded from vehicle

3. Editor Attributes

In the 3D mission editor attributes for "Cargo Size" and "Cargo Space" are available on suitable objects. These can be adjusted to change the respective value on a per-object basis - as well as to enable loading for objects and vehicles which would usually not support it.

If you wish to enable loading for an object/vehicle which does not have these editor attributes, see the ace_cargo_fnc_setSize and ace_cargo_fnc_setSpace functions.

4. Scripting

4.1 Disabling cargo for a mission object

To disable cargo for a mission object use:

[this, -1] call ace_cargo_fnc_setSize;

4.2 Adjusting cargo size of an object

ace_cargo_fnc_setSize Note that this function can be used to make objects loadable/unloadable (set to -1 for unloadable).

 * Set the cargo size of any object. Has global effect.
 * Adds the load action menu if necessary.
 * Negative size makes unloadable.
 *
 * Arguments:
 * 0: Object <OBJECT>
 * 1: Cargo size <NUMBER>
 *
 * Return Value:
 * None
 *
 * Example:
 * [object, 3] call ace_cargo_fnc_setSize

4.3 Adjusting cargo space of a vehicle

ace_cargo_fnc_setSpace Note that this function can be used to enable/disable a vehicle's cargo space (set to 0 to disable).

 * Set the cargo space of any object. Has global effect.
 * Adds the cargo action menu if necessary.
 *
 * Arguments:
 * 0: Vehicle <OBJECT>
 * 1: Cargo space <NUMBER>
 *
 * Return Value:
 * None
 *
 * Example:
 * [vehicle, 20] call ace_cargo_fnc_setSpace

4.4 Load cargo into vehicle

ace_cargo_fnc_loadItem (Also callable from cba event ace_loadCargo) Note first arg can be a in-game object or a classname of an object type.

 * Arguments:
 * 0: Item <OBJECT or STRING>
 * 1: Vehicle <OBJECT>
 *
 * Return Value:
 * Object loaded <BOOL>
 *
 * Example:
 * [object, vehicle] call ace_cargo_fnc_loadItem

4.5 Unload cargo from vehicle

ace_cargo_fnc_unloadItem (Also callable from cba event ace_unloadCargo)

 * Arguments:
 * 0: Item <OBJECT or STRING>
 * 1: Vehicle <OBJECT>
 * 2: Unloader <OBJECT> (default: objNull)
 *
 * Return Value:
 * Object was unloaded <BOOL>
 *
 * Example:
 * [object, vehicle] call ace_cargo_fnc_unloadItem
