Blueprint generate C++

No. You need to create the c++ class as a subclass of the class that the blueprint is a subclass of. Once you have done that, then you need to reparent your blueprint class on the c++ class you have created.

With the blueprint open in the editor, go to file->Reparent Blueprint


I ve generated some BluePrint quickly, but I have the need to write some C++ code, I want use in my blueprints.
I see it is possible to generate some Blueprint from C++ class, but is it possible to generate the C++ files from blueprints?

ok. But how do you reparent?
