Light Event System enables you to send and receive UObject-based events in both C++ and Blueprint. It's an implementation of the Observer pattern in the Unreal Engine ecosystem.

The plugin includes:

  • An UEventSystem class. Objects can listen for events that are relayed through UEventSystem's instances.
  • A global event system subsystem for convenience.
  • A set of basic event types.
  • Unit tests.

Why use this system?

  • Allows you to get rid of tight coupling in your codebase by making your modules dependent only on the Event System and a set of events relevant for them.
  • Event System is customizable via hook methods that allow you to easily change the way events are sent and received, if you need the extra flexibility.
  • Very easy to create event types.
  • It's possible to send and listen to events on FName-based channels.
  • Can be used conveniently in both C++ and Blueprint!
