thanks to those of you who provided an answer to my inquiry. I just think UE/Epic could develop some form of online material that goes in depth, kind of like a book but that they can update as they see fit. I followed the paper 2d tutorial by zack parish on youtube and took notes of pretty much everything, but as cool as it was, I still need to know things like score system, enemy spawn, damage etc etc. And how about if I want to create an endless runner and so on and so forth
