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.

Namespace Redux

As your applications get more complicated, you'll start to section off your code into namespaces, ensuring that you have control over where and when it's accessed. You'll also use third-party software tools and plugins—to save on time implementing a feature from the ground up that someone else has already made available. Both of these scenarios show that you're progressing in your programming knowledge, but they can also cause namespace conflicts.

Namespace conflicts happen when there are two or more classes or types with the same name, which happens more than you'd think. Good naming habits tend to produce similar results, and before you know it, you're dealing with multiple classes named Error or Extension, and Visual Studio is throwing out errors. Luckily C# has a simple solution to these situations: type aliasing.

Type aliasing

Defining a type alias lets you explicitly choose which conflicting type...
