If your application has a concept of Games or Game Sessions, the LyokoPluginLoader provides two events to let the plugins know of the state of the current Session.
This event is to signify that a game-session has started.
You can call the event with:
GameStartEvent.Call(boolstory=false);
The boolean story signifies whether or not the game-session is a 'story-mode'. What this means is largely application-dependant.
It's false unless stated otherwise.
