Hello MineStein. So I don't really know of any quality tutorials, but I can point you in some of the right directions. So, as you probably know, Minecraft is coded in Java, so that's the programming language you'll be needing to get familiar with. For coding with Java, I recommend using Eclipse as your editor. It has syntax highlighting and does recommendations, which are both useful. I'm sure there are some tutorials on YouTube, and you can always google Java tutorials. I hope this can help you get started in your search for tutorials!
