## General code structure

Unity uses C# scripts. \
There is no "main"-class in Unity scripts. \
Each script that is put on a `GameObject` can have a `Start` method (called once when the `GameObject` is created), an `Awake` method (called once before `Start`), and an `Update` method (called on each frame). \
