Creating Augmented Reality Apps with Unity and AR Foundation

Classes

Explore the core concept of classes in C# programming for Unity development. Understand how to create reusable and modular code through properties, methods, constructors, inheritance, polymorphism, and encapsulation. This lesson helps you build a strong foundation in object-oriented programming, essential for developing interactive and maintainable AR applications.

Introduction

Classes are one of the fundamental building blocks of object-oriented programming and are an essential concept in C# with Unity. In this lesson, we’ll explore what classes are, how they work, and how to use them to create reusable and modular code in Unity.

What are classes?

A class is a blueprint for creating objects with similar characteristics and behaviors. It defines an object’s properties and methods, which developers can use to create instances of the class.

Here’s an example of a simple class in C#:

C#
public class Player {
    public string name;
    public int health;
    
    public void TakeDamage(int damage) {
        health -= damage;
    }
}

In this example, we’ve created a class called Player that has two properties (name and health) and one method (TakeDamage). These properties and methods can be accessed and modified by creating instances of the Player class.
