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.

Unlike the methods we define ourselves, methods belonging to the MonoBehaviour class are called automatically by the Unity engine according to their respective rules. It's important in most cases to have at least one MonoBehaviour method in a script to kick off your own code.

You can find a complete list of all available MonoBehaviour methods and their descriptions here: https://docs.unity3d.com/ScriptReference/MonoBehaviour.html.

The Start method

Unity calls this method on the first frame where a script is enabled. SinceMonoBehaviourscripts are almost always attached to GameObjects in a scene, their attached scripts are enabled at the same time they are loaded when you hit play. In our project,LearningCurveis attached to the Main Camera GameObject, which...
