[Plugin] Leap Motion - Event Driven

Back when I started with the hydra plugin (4.0) there wasn’t as much documentation so I wasn’t aware of the UE4 delegate system. I was looking for an architecture that would allow me to add event driven, auto-ticking to any class where you would’ve wanted it in C++. As time went on and I learned more about UE4 it became clear that components offer more flexibility and you could receive events by adding an interface. This allowed each plugin to now extend functionality directly in blueprints rather than C++. I still believe this, along with including convenience characters/actors that can be used for common use cases (e.g. rigged character), is the best approach.

If you can see a way to make your code cleaner by using the UE delegate system, use it. Let us know how it goes!

Thank you for your reply.

One major advantage of the UE delegate system is that you can have more than one listener. I think this could still work with the UActorComponent. It might be possible to have many Actors with LeapController within. Anyway, the documentation is still not quite there yet so I don’t fully get it and will probably not use it.

I have another question for you but it’s not Leap-specific so I will ask by PM.

Thanks again!
