Maybe I am overseeing things, perhaps the lump of code i am writing basically is the start of any Game code and you expand on that, but i am still only on chapter 2, and am starting to write the skeleton code of the C++ Game Engine tonight, and that means I will hopefully understand it all a bit more. DirectX seems to be extremely complex for a noob like me. But I am still hoping to get through this book in 2 weeks, and then focus on the next books and try to expand the game engine with more specialized books, mostly I am hoping to have something done soon though.
It is so far an interesting journey so to say, but its a lot of work and sinec I have a bad memory it can be hard for me to keep remembering all this code and functions and the order of what you need to do. But I hope by keeping notes and keeping the source codes i wrote near me I should be able to start experimenting with my own things soon.
