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.

The Object-Oriented mindset

If class and struct instances are the blueprints of our programs, then OOP is the architecture that holds everything together. When we refer to OOP as a programming paradigm, we are saying that it has specific principles for how the overall program should work and communicate. Essentially, OOP focuses on objects rather than pure sequential logic—the data they hold, how they drive action, and, most importantly, how they communicate with each other.

Things in the physical world operate on a similar level; when you want to buy a soft drink, you grab a can of soda, not the liquid itself. The can is an object, grouping related information and actions together in a self-contained package. However, there are rules when dealing with objects, both in programming and the grocery store. Who can access them, different variations, and generic actions all play into the objects that are all around us. In programming terms, these rules are the main...
