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>

The basics of physics


In order to make our games more realistic and therefore simulate real life, we make use of physics. However, to make use of it within our games, we first need to understand the basics of physics.

Just as a game needs rules in order to function, so too does the world around us. The natural world is governed by rules. The science that explains how the world is governed by these rules using measurable data is known as natural science. Physics is a branch of natural science that explains matter and the motion of matter through time and space.

Physics found in the real world

Physics covers an extremely vast range of concepts, and as such we will only look at the relevant basic quantities that provide the foundations of physics. The following are the basic quantities:

  • Matter: Just as matter in the world is everything around us that is made up of atoms and molecules, in relation to games, the objects in our game are the matter in the game world.

  • Time: We use time to set intervals...
