This is an older tutorial that is a bit long and drawn out but if you're interested in what game coding actually looks like this will give you a great real world look at what it's like. It's several hours long but it shows you that even with basic coding knowledge you can learn how to do it. All you need is ~6 months of coding experience and determination and you can make a basic FPS game.
This tutorial uses Dark GDK which is a "Game Development Kit", self explanatory right?
I hope you enjoy
