What exactly do I need to know in c# to create a game in unity?

Question

Unity

I can’t even really imagine what I need to write there in order, for example, to implement control on awsd in a little man model. In general, I don’t understand the connection between the models on the stage and scripts, I don’t understand what I should write there to implement any idea and how it generally works. For now, at most, in C # I can write "Hello, World!" and that's it. And while I do not want to pay money for all sorts of courses and books.

Answer 1

As the saying goes "you need a strong knowledge of the language." In my understanding, this is when, when implementing a task, the language does not interfere with you, but helps. Those. you do not think about HOW to express the algorithm in c#. And think about the algorithm itself.
Judging by what you wrote, you are still very early in the unit. Start with a clean sharp. Where to start a clean sharp - there are a lot of such questions on the toaster.

Answer 2

I agree with GavriKos, but I want to add my own, that knowledge about C # up to and including OOP is enough in UnityEngine, and there you will already find a book with its libraries.
I recommend to read

C# 7 programming language and .NET and .NET Core platforms

up to and including the OOP part, sorry for the tautology.
