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.

Time for action – adding method parameters

Let's update GenerateCharacter() so that it can take in two parameters:

  1. Add two method parameters: one for a character's name of the string type, and another for a character's level of the int type.
  2. Update Debug.Log() so that it uses these new parameters.
  1. Update the GenerateCharacter() method call in Start() with your arguments, which can be either literal values or declared variables:

Here, we defined two parameters, name (string) and level (int), and used them inside the GenerateCharacter() method, just like local variables. When we called the method inside Start(), we added argument values for each parameter with corresponding types. In the preceding screenshot, you can see that using the literal string value in quotations produced the same result as using characterLevel:

Going even further with methods, you might be wondering how we can pass values from inside the method and back out again...
