I had created a Blueprint Enum, but i want to use this value create a variable in my C++. Is anyone knows how to create?

You can’t declare an enum in blueprint and use it as a type in C++, it’s the other way around. Declare your enum in C++ first and make it a BlueprintType

The reflection system in Unreal is “mostly” a one way thing. it isn’t impossible to pierce through it, but it gets messy, and is prone to Runtime String Resolution “problems”. Unless you are making an editor utility specifically to work with Blueprint stuff in C++, or you are 120% sure the things you are looking for in the Blueprints “WILL NOT CHANGE”, you are better off treating Blueprints as child-classes that just graduated high-school are responsible for themselves with the ability to phone home to the C++ Parents.

the short answer is: if C++ needs to know about something specific: Enums, Structs, Classes their base version should be defined in C++.

you can take a look here for more details.

How can I get access to a structure defined in blueprints through C++?

Structures made in blueprints, same as blueprints themselves exist virtually in UE4 reflection system and can be accessed only in runtime. That means you need to grab values of struct as well of structure of struct from reflection system, but you won’t be able to directly reference it like you normaly do in C++ as they are not declared in C++. UE4 reflection system is system that stores information about code structure, blueprints use it too, in fact it is system that makes blueprint works in s…
