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

Creating a simple AR game

As we discussed previously, the idea is to create a simple game where we can move our player while moving a real-life image, and also put in some Enemy Spawners by just tapping where we want them to be, such as a wall, the floor, a table, and so on. Our player will automatically shoot at the nearest Enemy, and the enemies will shoot directly at the player, so our only task will be to move the Player so that they avoid bullets. We are going to implement these game mechanics using scripts very similar to the ones we used in this book's main project.

In this section, we will develop the following AR game features:

  • Spawning the Player and Enemies
  • Coding the Player and Enemy behavior

First, we are going to discuss how to make our Player and Enemies appear on the app, specifically in real-world positions, and then we will make them move and shoot each other to create the specified gameplay mechanics. Let's start with spawning.
