Package wyvern.lib.event Description

Contains Events and EventListeners for being notified when various events happen in the Wyvern system.

Wyvern has lots of notification types:

• Hooks (Hookable and HookCallback)
• specific notifications like WalkNotify and PickupInterest
• Publish/Subscribe messages
• method-hooks
• the Event notifications from this package

We're trying to deprecate the use of method-hooks, at least in the core game engine, and replace them with "strongly-typed" event notifications. A tutorial is in the works on how all the different notifications are used in Wyvern.
