Learning C# by Developing Games with Unity 2019 - Fourth Edition

By: Harrison Ferrone

Overview of this book

Learning to program in today’s technical landscape can be a daunting task, especially when faced with the sheer number of languages you have to choose from. Luckily, Learning C# with Unity 2019 removes the guesswork and starts you off on the path to becoming a confident, and competent, programmer using game development with Unity. You’ll start off small by learning the building blocks of programming, from variables, methods, and conditional statements to classes and object-oriented systems. After you have the basics under your belt you’ll explore the Unity interface, creating C# scripts, and translating your newfound knowledge into simple game mechanics. Throughout this journey, you’ll get hands-on experience with programming best practices and macro-level topics such as manager classes and flexible application architecture. By the end of the book, you’ll be familiar with intermediate C# topics like generics, delegates, and events, setting you up to take on projects of your own.

Handling exceptions

Efficiently incorporating errors and exceptions into your code is both a professional and personal benchmark in your programming journey. Before you start yelling, "Why would I add errors when I've spent all this time trying to avoid them!" you should know that I don't mean adding errors to break your existing code. It's quite the opposite—including errors or exceptions and handling them appropriately when pieces of functionality are used incorrectly makes your code base stronger and less prone to crashes, not weaker.

Throwing exceptions

When we talk about adding errors, we refer to the process as exception throwing, which is an apt visual analogy. Throwing exceptions is part of something called defensive programming, which essentially means that you actively and consciously guard against improper or unplanned operations in your code. To mark those situations, you literally throw out an exception from a method...
