Thank you for your answer, but I still don’t understand how to edit the .cpp file when a blueprint from this class was made. I don’t see the .cpp and .h files in Visual Studio to edit it. I can only open the .h file in Visual Studio from Unreal Editor.
To better understand for you:
1/ I created MyActor.cpp and MyActor.h in VS
2/ I made a blueprint MyActorBP from these C++ files
3/ All works great
4/ I wish to edit MyActor.cpp to for example add something to the code, but I can’t find the way to open the file
5/ I can open only MyActor.h in VS and edit it
I have just found the MyActorBP to edit it. I simple named it different and forgot :). But I still don’t know how to find the .cpp file to edit it.
I can find the option to open and edit in VS the .h file, but I can’t see a way to do the same with the .cpp file. I can open only the blueprint. Isn’t possible to edit the .cpp file when the blueprint for the class has been made? No way to come back to the .cpp source? And what if I change the h. file and add for example a property or function?
