Events and Triggers

The game uses the trigger/event features found in the Unreal Engine.  When you hit a bumper (or other object) it sends out an event to the other actors.  If the tag value of an actor matches the Event name of the one sending the event, the actor is triggered.  Depending on the actor triggering causes different things to happen, such as toggling an active flag, raising your score, giving a free ball, etc.  In the editor you can tell if two actors are related by events if there is a red line connecting them.
