About the Reviewers
Elizabeth Keegan is a practitioner in the field of game design and art. She obtained her bachelors degree from Cleveland's very own Institute of Art and masters degree from UC Berkeley in Fine Art. Currently, she's heading the continued growth of the Game Design program at Notre Dame College. Game design has been her primary focus for many years and spans a range of disciplines. She has worked both collaboratively and independently on many projects concerning topics such as Artificial Intelligence, Air Pollution, Autism, and Mental Therapy. More importantly, Elizabeth has taught across a range of age groups and classrooms. She has worked alongside high school students in summer camps, 9th grade year, round programs, and college classrooms. All of these experiences have taught her the power of game development and its ability to facilitate critical thinking and creative problem solving among many other crucial skills in today’s workplace.
She is the current a game design instructor at Notre Dame College in South Euclid, Ohio, and has worked alongside Rachel Morris who is the head of the art department.
I would like to thank both Abdelrahman Saher and Francesco Sapio,for providing yet another accessible resource to those interested in game development. I would also like to thank Sanchita Mandal and Paushali Desai for including me in the review process.
Melody Kaye Cariaga graduated from De La Salle College of St. Benilde with a BS in Information Technology and a specialization in game design and development. This program was a first in the Philippines; on February 2013, she was a part of the very first batch of graduates with the title of cum laude under her name.
Since February 2013, she has been working as a game developer. On her first job, she developed HTML5 games for three major American cable and satellite television networks aimed mainly at the child and adolescent demographic. In May 2015, she started working for Xurpas Inc., the first tech startup in Southeast Asia to go on initial public offering, as one of their Unity developers that create Android games.
Melody is a strong, hardworking woman, who always aims to do better and be better in life. She is a well-organized individual who never fails to give more than 100% in her work and never loses sight of her goal. Even though she is driven, she still has time to enjoy playing games, listening to music, and watching movies. She never loses sight of who she really is.
For all the success and achievements I have received throughout my career, I would like to thank God Almighty for His everlasting grace, my family for their never-ending guidance and support, and my special someone for his trust in everything I do.

Chapter 1. Sprites
As we start our journey into the world of 2D game development, let's start this chapter by talking about the most important elements of creating 2D games. A 2D sprite is a two-dimensional image that is rendered on your screen while the game is still running.
In this chapter, we will start working on our own Platformer game. It consists of a character that must navigate through a platform level by jumping and running to achieve certain tasks. Along the way, we will learn how to use sprites and how Unity handles them. In this particular chapter, we will cover:
2D mode
Unity has a 2D mode that allows us to quickly set up the project for 2D game development. In fact, the main reason to use this mode is to automatically import new assets as Sprites.
When creating a new project, you have the option to choose between the 3D and the 2D mode. Let's select the 2D mode, as shown in the following image:
Now, we need to import the standard assets that we will use to build our game. Click on Asset packages and select 2D.
Note
Unity doesn't come with the standard packages, you need to download them from the official website.
Finally, we can click on Create project. If you have used Unity before for 3D game development, you will notice a few differences in the default interface. In particular, the 2D view is already selected:
Furthermore, the camera in new scenes will always be orthographic, which is exactly what we want:
Having selected the 2D mode doesn't mean that you cannot change it any more. In fact, you can change it to 3D mode whenever you want by going to Edit | Project Settings | Editor and selecting 3D under Default Behavior Mode.
This can come in handy when adding 3D models to your 2D project and vice versa. It is recommended that you switch before importing 2D sprites or 3D models to the appropriate mode since Unity will import textures accordingly.
Custom packages
During the course of this book, we will use custom packages, since we don't have time to create all the graphics on our own.
For our first game, we are going to use a package from http://kenney.nl
