16.10. Object Orientation in C#: Attributes and Static Methods

Object orientation is one of the most used programming paradigms today and is fundamental for programming games with Unity. C# is an object-oriented language, which means it allows developers to structure their programs in a way that groups related variables and functions into objects - an approach that facilitates modularity and code reuse. In this context, static attributes and methods are important concepts that need to be understood to work effectively with object orientation in C#.

Before we dive into static attributes and methods, it's important to understand what attributes and methods are in general. In C#, an attribute is a variable that is defined within a class and that stores some type of data that is relevant to that class. For example, in a "Player" class, you might have attributes like "health", "score", and "name".

Methods, on the other hand, are functions that are defined within a class and that perform some action that is relevant to that class. For example, in the "Player" class you can have methods like "Jump", "Shoot" and "Move".

Now, let's talk about static attributes and methods. In C#, a static attribute or method is one that belongs to the class itself, and not to a specific instance of that class. This means you can access a static attribute or method without having to create an instance of the class.

To illustrate, let's assume we have a "Game" class with a static attribute "highScore". Since "highScore" is static, it belongs to the "Game" class as a whole, not a specific instance of "Game". This means that you can access "highScore" directly through the class, as in "Game.highScore", rather than needing to create a "Game" object and then access "highScore" through that object.

Static methods work in a similar way. If we have a static "Reset" method in the "Game" class, we can call it directly through the class, as in "Game.Reset()", instead of needing to create a "Game" object and then call "Reset" through of that object.

Static attributes and methods are useful in many situations. For example, they can be used to store and manipulate information that is relevant to the class as a whole, rather than a specific instance of the class. In our example, "highScore" is a good candidate for a static attribute, as it is something that is relevant to the game as a whole, rather than a specific player or level.

In summary, object orientation in C# is a fundamental concept for programming games with Unity, and static attributes and methods are an important part of this. They allow developers to structure their programs in a way that groups related variables and functions into objects, facilitating modularity and code reuse. Additionally, they allow developers to store and manipulate information that is relevant to the class as a whole, rather than a specific instance of the class.
