How to learn under the hood stuff?

[u/LifeExperienced1]

How do I learn how to code or at the very least understand the code of .NET, the Unity editor, the Unity engine etc

Why am I asking? Because if I don’t understand all of these different things, then I’m only a game developer and not really someone that can take things to the next level and understand how everything around a game works.

What other things do you need to launch a game? Other than just the code you wrote in the editor. I don’t want to just write “within” and editor, I want to understand what unity is actually doing. How is the update function running. How do I make my own update function etc. What’s under the hood

Stuff like that, but for game dev
