C++ and blueprints

Hello everyone,
I am still very new to the engine, and atm i am experiencing some problems with understanding the relations between C++ classes and blueprints. Previously I tried to make my character move to different objects in a level blueprint, but now I want to extent the functionality using C++. So I created a new project (not to break the old one), and now I am stuck, as I don’t know where to write the code that would do the same things as my level blueprint class. Please, give some brief explanation of what’s happening and how I should act in this situation.
Thanks in advance.

First you have to describe what the blueprint class was doing. Maybe show the code. What I can say is that the level blueprint is usually not used that much. Most happen inside each blueprint.
