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.

Detecting collisions

As you can see, proper Physics settings can be complicated and very important, but now that we have tackled that, let's do something with those settings by reacting to the contact in different ways and creating a Health System in the process.

In this section, we will examine the following collision concepts:

  • Detecting Trigger events
  • Modifying the other Object

First, we are going to explore the different collision and trigger events Unity offers to react to contact between two Objects through the Unity collision events. This allows us to execute any reaction code we want to place, but we are going to explore how to modify the contacted Object components using the GetComponent function.

Detecting Trigger events

If Objects are properly configured, as previously discussed, we can get two reactions, triggers and collisions. The Collision reaction has a default effect that is blocking the movement of the Objects, but we can add custom...
