Hands-On Unity 2021 Game Development - Second Edition

By: Nicolas Alejandro Borromeo

Overview of this book

Learning how to use Unity is the quickest way to creating a full game, but that’s not all you can do with this simple, yet comprehensive suite of video game development tools – Unity is just as useful for creating AR/VR experiences, complex simulations, real-time realistic rendering, films, and practical games for training and education. Hands-On Unity 2021 Game Development outlines a practical journey to creating your first full game from the ground up, building it step-by-step and applying your knowledge as you progress. Complete with hands-on tutorials and projects, this easy-to-follow guide will teach you how to develop the game using several Unity tools. As you advance, you will learn how to use the Unity engine, create simple scripts using C#, integrate graphics, sound, and animations, and manipulate physics to create interesting mechanics for your game. You’ll be able to apply all the knowledge that you gain to a real-world game. Later chapters will show you how to code a simple AI agent to challenge the user and use profiling tools to ensure that the code runs efficiently. Finally, you'll work with Unity's AR tools to create AR experiences for 3D apps and games. By the end of this Unity book, you will have created a complete game and built a solid foundation in using a wide variety of Unity tools.

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 moving through custom scripting using the Transform API. However, every dynamic Object should move using the Rigidbody API functions in such a way that the Physics system understands this, 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 by learning how to move Objects the correct physical way; that is, by using force. 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 so that they have a more responsive and appealing behavior.

Applying forces

The Physically accurate way of moving an Object is through forces, which affect the Object...
