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.

Polymorphism

Polymorphism is the Greek word for many-shaped and applies to OOP in two distinct ways:

  • Derived class objects are treated the same as parent class objects. For example, an array of Character objects could also store Paladin objects, as they derive from Character.
  • Parent classes can mark methods as virtual, meaning that their instructions can be modified by derived classes using the override keyword. In the case of Character and Paladin, it will be useful if we could debug different messages from PrintStatsInfo for each one.

Polymorphism allows derived classes to keep the structure of their parent class while also having the freedom to tailor actions to fit their specific needs. Let's take this new knowledge and apply it to our character debug method.
