Learning Unity 2D Game Development by Example

By: Venita Pereira

Overview of this book

<p>If you are looking for a guide to create 2D games using Unity, look no further. With this book, you will learn all the essentials of 2D game development by creating five real-world games in a step-by-step manner throughout the course of this book.</p> <p>Starting with a blank scene, you will learn all about the new Unity 2D toolset, which will enable you to bring your scene to life. You will create characters, make them move, create some enemies, and then write code to destroy them. After figuring out all the necessities of creating a game, this book will then assist you in making several different games: games with collision, parallax scrolling, Box2D, and more.</p> <p>By the end of this book, you will not only have created several small games, but you will also have the opportunity to put all your new-found knowledge into creating and deploying a larger, full game.</p>

Why do we need code?


In order to create any type of game, we need to understand code because the pieces of code are the instructions that tell the game engine (Unity) when and how you want something to occur at any given point.

Programming languages

In order to create code, we use a programming language, which is an intermediary language that represents the instructions that we tell the computer processor.

Levels of programming languages

There are three levels of programming languages:

  • Machine language

  • Assembly language

  • High-level languages

Machine language

Computers do not understand human language; therefore, we need to communicate with the computer processor via machine language.

Machine language, also known as binary code, consists of a combination of 0s and 1s that represent high and low electrical voltages. These 0s and 1s are known as bits (binary digits). We can then make use of data by representing the data using these bits.

All data has an area on the computer or device where it is stored...
