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.

Object hierarchies

Some complex objects may need to be separated in sub-objects, each one with its own components. Those sub-objects need to be somehow attached to the main object and work together to create the necessary object behavior.

In this section, we will cover the following concepts related to components:

  • Parenting of objects
  • Possible uses

Parenting of objects

Parenting consists of making an object the child of another, meaning that those objects will be related to each other. One type of relationship that happens is a Transform relationship, meaning that a child object will be affected by the parent's Transform. In simple terms, the child object will follow the parent, as if it is attached to it. In an example, imagine a player with a hat on their head. The hat can be a child of the player's head, making the hat follow the head while they are attached.

In order to try this, let's create a capsule that represents an enemy and a cube...
