How to do that?

hi @wantg

Im not sure i entirely understand you but…

If you wish to create an actor using c++ that contains components, events and functions just like a blueprint does, you can do that in code of course.

Creating a custom Actor in C++ | Unreal Engine 4 Scripting with C++ Cookbook (packtpub.com)

Or if you want to provide access to functions you make in c++ available to blueprints in game you can do that also.

I hope i answered what you require

@High500 hi High500 Thank you for reply.
It seems that my question is a little strange.

I’m a programmer I know how to write Actors in CPP, make derives Blueprints and Put them to work.

I have to open the Unreal editor to make blueprints ( with parameters manual ) for the level designer or gameplay designer.

I am trying to find a way to create Blueprint without using Unreal editor or any other GUI tools.
Like programming in the traditional way.
