Events

Events are a powerful tool provided by Unity. The Architecture Toolkit extends this system by allowing events to be saved as ScriptableObjects. This means the same event can be referenced and listened to by multiple systems throughout the project.

📅 Game Event

An event can be created through the Asset menu, Zigurous > Events > Game Event. There are no properties on an event, but they can be extended with subclasses if needed. See the GameEvent Scripting API.

🎧 Game Event Listener

A GameEventListener component can be added to any game object that needs to listen for an event. This is a class that derives from MonoBehaviour and will register and unregister itself as a listener for the specified event. The listener also declares a standard UnityEvent response property that is invoked when the event is raised.

🎫 Event Reference

The EventReference class allows a UnityEvent or GameEvent to be referenced. The option to switch between the two choices is available in the editor. Anywhere you might declare a variable as a UnityEvent or a GameEvent consider declaring it as an EventReference for more flexibility.
