By: Harrison Ferrone

Overview of this book

Over the years, the Learning C# by Developing Games with Unity series has established itself as a popular choice for getting up to speed with C#, a powerful and versatile programming language that can be applied in a wide array of application areas. This book presents a clear path for learning C# programming from the ground up without complex jargon or unclear programming logic, all while building a simple game with Unity. This fifth edition has been updated to introduce modern C# features with the latest version of the Unity game engine, and a new chapter has been added on intermediate collection types. Starting with the basics of software programming and the C# language, you’ll learn the core concepts of programming in C#, including variables, classes, and object-oriented programming. Once you’ve got to grips with C# programming, you’ll enter the world of Unity game development and discover how you can create C# scripts for simple game mechanics. Throughout the book, you’ll gain hands-on experience with programming best practices to help you take your Unity and C# skills to the next level. By the end of this book, you’ll be able to leverage the C# language to build your own real-world Unity game development projects.

The Start method

Unity calls this method on the first frame where a script is enabled. Since MonoBehaviour scripts are almost always attached to GameObjects in a scene, their attached scripts are enabled at the same time they are loaded when you hit Play. In our project, LearningCurve is attached to the Main Camera GameObject, which means that its Start() method runs when the Main Camera is loaded into the scene. Start() is primarily used to set up variables or perform logic that needs to happen before Update() runs for the first time. 

The examples we've worked on so far have all used Start(), even though they weren't performing setup actions, which isn't normally the way it would be used. However, it only fires once, making it an excellent tool to use for displaying one-time-only information on the console.

Other than Start(), there's one other major Unity method that you'll run into by default: Update(). Let&apos...
