Explore the fundamental C# data types used in Unity, including integers, floats, strings, booleans, GameObjects, vectors, and quaternions. Understand how each type applies to game and AR development, enabling you to use variables efficiently and manage memory properly.

We'll cover the following...

Introduction

C# is a powerful programming language commonly used in game development, and Unity is a popular game engine that uses C# as its primary scripting language. In this lesson, we’ll explore some of the critical concepts and syntax of C# in Unity and provide examples and illustrations to help you understand the language.
