Event Handlers

Event handlers in ACE3 are implemented through our event system. They should be used to trigger or allow triggering of specific functionality.

The commands are listed below.

  • [eventName, eventCodeBlock] call ace_common_fnc_addEventHandler
    adds an event handler with the event name and returns the event handler id.
  • [eventName, args] call ace_common_fnc_globalEvent
    calls an event with the listed args on all machines, the local machine, and the server.
  • [eventName, args] call ace_common_fnc_serverEvent
    calls an event just on the server computer (dedicated or self-hosted).
  • [eventName, targetObject(s), args] call ace_common_fnc_targetEvent
    calls an event just on the targeted object or list of objects.
  • [eventName, args] call ace_common_fnc_localEvent
    calls an event just on the local machine, useful for inter-module events.

Events can be removed or cleared with the following commands.

  • [eventName, eventHandlerId] call ace_common_fnc_removeEventHandler
    will remove a specific event handler of the event name, using the ID returned from ace_common_fnc_addEventHandler.
  • [eventName] call ace_common_fnc_removeAllEventHandlers
    will remove all event handlers for that type of event.

Pattern:

// tapper machine
["tapShoulder", [_target], [otherArguments]] call EFUNC(common,targetEvent);

// target machine XEH_preInit.sqf
PREP(onTapShoulder);
["tapShoulder", FUNC(onTapShoulder) ] call EFUNC(common,addEventHandler);
