ace |
1. Event Handlers
Event handlers in ACE3 are implemented through CBA's Event System. They should be used to trigger or allow triggering of specific functionality.
2. Events List
ACE3 uses many events internally, this is not a complete list; but it should list most publicly usable events.
2.1 Fired Event Handlers (ace_common)
Different events for what type of unit has fired.
E.G.: If you only need to do action when player's weapon fires, this will be faster than adding an XEH for everything.
The vehicle events will also have the following local variables available _gunner (OBJECT), _turret (ARRAY).
