wiki	Events Framework	Explains how to use CBA event handlers with ACE3 events used to trigger or allow triggering of specific functionality and lists all documented events.	framework	5	wiki	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).
