Casting to a UInterface implemented in native code

One advantage that UInterfaces provide you with as a developer is the ability to treat a collection of heterogeneous objects that implement a common interface as a collection of the same object, using Cast< > to handle the conversion.

Please note that this won't work if your class implements the interface through a Blueprint.

Getting ready

You should have a UInterface and an Actor implementing the interface ready for this recipe.

Create a new game mode using the wizard within Unreal, or reuse a project and GameMode from a previous recipe.
