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

Gathering information with sensors

An AI works first by taking in info about its surroundings, then that data is analyzed to determine an action and finally, the chosen action is executed, and as you can see, we cannot do anything without information, so let's start with that part. There are several sources of information our AI can use, such as data about itself (life and bullets) or maybe some game state (winning condition or remaining enemies), which can be easily found with the code we saw so far, but one important source of information is also the AI senses. According to the needs of our game, we might need different senses such as sight and hearing, but in our case, sight will be enough, so let's learn how to code that.

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

  • Creating Three-Filters sensors
  • Debugging with Gizmos

Let's start seeing how to create a sensor with the Three-Filters approach.
