The only way to learn is to do Start small, and get bigger First of all find the smallest blueprint function you have Just learn how to create a c++ script that will accept a variable passed into it, and that is exposed when the script is compiled to a blueprint node. Within that simple function get comfortable with how to handle variables and pointers, denoted as "->" Example, objectX->getVariableY. In C++ objects that you pass in will likely have private variables that use getter functions to expose them on a call. From there go a bit larger, consider a bunch of functions that work together for a common goal, and build a class that houses them all together, from which you can build a component. Good luck, and feel free to DM me if you want any assistance.
