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.

Iteration statements

We've accessed individual collection elements through the subscript operator, and collection type methods, but what do we do when we need to go through the entire collection element by element? In programming, this is called iteration, and C# provides several statement types that let us loop through (or iterate over, if you want to be technical) collection elements. Iteration statements are like methods, in that they store a block of code to be executed; unlike methods, they can repeatedly execute their code blocks as long as their conditions are met.

For loops

The for loop is most commonly used when a block of code needs to be executed a certain number of times before the program continues. The statement itself takes in three expressions, each with a specific function to perform before the loop executes. Since for loops keep track of what iteration they're on, they are best suited to Arrays and Lists.
