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 – assigning variables in Unity

Let's change LearningCurve to show how to assign a GameObject component using drag and drop:

  1. Comment out the following line of code, where we used GameObject.Find() to retrieve and assign the Directional Light object to the directionLight variable:
             //directionLight = GameObject.Find("Directional Light");
  1. Select the Main Camera GameObject, drag Directional Light to the Direction Light field in the LearningCurve component, and click on Play:

The Directional Light GameObject is now assigned to the directionLight variable. No code was involved because Unity assigned the variable internally, with no change to the LearningCurve class.

It is important to understand a few things when deciding whether to assign variables using drag and drop or GameObject.Find(). First, the Find() method is marginally slower...
