Game Development with Unity for .NET Developers

By: Jiadong Chen

Overview of this book

Understand what makes Unity the world’s most widely used real-time 3D development platform and explore its powerful features for creating 3D and 2D games, as well as the Unity game engine and the Microsoft Game Dev, including the Microsoft Azure Cloud and Microsoft Azure PlayFab services, to create games. You will start by getting acquainted with the Unity editor and the basic concepts of Unity script programming with C#. You'll then learn how to use C# code to work with Unity's built-in modules, such as UI, animation, physics, video, and audio, and understand how to develop a game with Unity and C#. As you progress through the chapters, you'll cover advanced topics such as the math involved in computer graphics and how to create a custom render pipeline in Unity with the new Scriptable Render Pipeline, all while optimizing performance in Unity. Along the way, you'll be introduced to Microsoft Game Dev, Azure services, and Azure PlayFab, and using the Unity3D PlayFab SDK to access the PlayFab API. By the end of this Unity book, you'll have become familiar with the Unity engine and be ready to develop your own games while also addressing the performance issues that you could encounter in the development process.

Working with the transformation matrix

In game development, the transformation matrix is also a common term. Specifically, we use the transformation matrix to encode transformations, including translation, rotation, and scaling transforms.

Unity provides us with the Matrix4x4 struct in C# to represent a standard 4x4 transformation matrix.

Figure 7.24 – A 4x4 matrix

As shown in Figure 7.24, a transformation matrix is a grid of numbers. Although it is a common term, we rarely use this matrix directly in scripts. This is because the calculation of the matrix is relatively cumbersome, and Unity, as an easy-to-use game engine, has encapsulated the complex calculations in the Transform class for us, and we only need to call some functions. Therefore, in this section, we only give a brief introduction to the transformation matrix.

Before we start, you should know that transformations include translation, rotation, scaling, and these operations can...
