Hands-On Unity 2020 Game Development

By: Nicolas Alejandro Borromeo

Overview of this book

Over the years, the Unity game engine has extended its scope from just being about creating video games to building AR/VR experiences, complex simulations, real-time realistic rendering, films, and serious games for training and education. Its features for implementing gameplay, graphics, and customization using C# programming make Unity a comprehensive platform for developing professional-level, rich experiences. With this book, you'll be able to build impressive Unity projects in a step-by-step manner and apply your knowledge of Unity concepts to create a real-world game. Complete with hands-on tutorials and projects, this easy-to-follow guide will show you how to develop your first complete game using a variety of Unity tools. As you make progress, you'll learn how to make the most of the Unity Editor and create scripts using the C# programming language. This Unity game development book will then take you through integrating graphics, sound, and animations and manipulating physics to create impressive mechanics for your games. You'll also learn how to code a simple AI agent to challenge the user and use profiling tools to ensure that the code runs in a performant way. Finally, you'll get to grips with Unity's AR Foundation for creating AR experiences for 3D apps and games. By the end of this book, you'll have developed a complete game and will have built a solid foundation using Unity's tooling ecosystem to develop game projects of any scale.

Chapter 20: Building the Project

Moving with Physics

So far, the Player, the only Object that moves with the Dynamic Collider Profile and the one that will move with Physics, is actually moving through custom scripting using the Transform API. Every dynamic Object should instead move using the Rigidbody API functions in a way the Physics system understands better, so here we will explore how to move Objects, this time through the Rigidbody component.

In this section, we will examine the following Physics movement concepts:

  • Applying forces
  • Tweaking Physics

We will start seeing how to move Objects the correct physical way, through forces, and we will apply this concept to the movement of our player. Then, we will explore why real physics is not always fun, and how we can tweak the Physics properties of our Objects to have a more responsive and appealing behavior.

Applying forces

The physically accurate way of moving an Object is through forces, which affect the Object's velocity. To...
