Exposing UInterface methods to Blueprint from a native base class

Being able to define UInterface methods in C++ is great, but they should be accessible from Blueprint too. Otherwise, designers or others who are using Blueprint won't be able to interact with your UInterface. This recipe shows you how to make a function from an interface callable within the Blueprint system.

How to do it...
