Getting Started with Unity 5.x 2D Game Development

By: Francesco Sapio

Overview of this book

Want to get started in the world of 2D game development with Unity? This book will take your hand and guide you through this amazing journey to let you know exactly what you need to build the games you want to build, without sacrificing quality. You will build a solid understanding of Unity 5.x, by focusing with the embedded tools to develop 2D games. In learning about these, along with accurate explanations and practical examples, you will design, develop, learn how to market and publish a delectable Tower Defense game about cupcakes versus pandas. Each chapter in this book is structured to give you a full understanding on a specific aspect of the workflow pipeline. Each of these aspects are essential for developing games in Unity. In a step-by-step approach, you will learn about each of the following phases: Game Design, Asset Importing, Scripting, User Interfaces, Animations, Physics, Artificial Intelligence, Gameplay Programming, Polishing and Improving, Marketing, Publishing and much more. This book provides you with exercises and homework at the end of each chapter so that you can level up your skills as a Unity game developer. In addition, each of these parts are centered on a common point of discussion with other learners just like you. Therefore, by sharing your ideas with other people you will not only develop your skills but you will also build a network.

Preface

The Unity Physics engine


Unity has a Physics engine integrated into it, which is able to handle both kinematic and dynamic types of rigid bodies as well as other physical entities such as clothes. It is divided into two parts: 2D Physics and 3D Physics. It's important to understand that although they can coexist together in the same scene, they are two separate entities; they cannot communicate between themselves. Physical objects under 2D Physics will not interact with physical objects under 3D Physics.

In this section, we will explore most of the 2D Physics engine of Unity. Although we will not use all the components presented here, it's important to master them all to become a better Unity developer.

Understanding Physics in Unity

In Chapter 2, Cooking Cupcake Towers, we learnt about script ordering and how it is executed. The first question we may wonder is when does the Physics engine occur when a frame is rendered? The answer is not straightforward, because the Physics engine runs multiple...
