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.

The life cycle of a script instance

In the previous section, we introduced basic concepts of scripting in Unity. Now, we will explain another important topic regarding scripting in Unity: the life cycle of a script instance.

We already know that the Unity C# API does not include the internal logic of the engine and the event functions on the script are triggered by the engine's C/C++ code. Therefore, in order to use the Unity engine correctly, it is very important to understand the order of execution for event functions and the life cycle of a C# script in Unity.

We can divide the Unity event functions into the following categories depending on their purpose :

  • Initialization
  • Update
  • Rendering

Let's discuss them next.

Initialization

If you are familiar with developing .NET applications, you may be surprised by script initialization in Unity because Unity scripts do not use constructors for initialization. Instead, Unity provides some engine...
