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.

Adding final details

We have two things missing here, the Enemy is not shooting any bullets and it doesn't have animations. Let's start fixing the shooting by doing the following:

  1. Add a bulletPrefab field of the GameObject type to our EnemyFSM script and a float field called fireRate.
  2. Create a function called Shoot and call it inside AttackBase and AttackPlayer:

    Figure 18.39 – Shooting function calls

  3. In the Shoot function, put a similar code as the one used in the PlayerShooting script to shoot bullets at a specific fire rate, as in the following screenshot. Remember to set the Enemy layer in your Enemy Prefab, in case you didn't before, to prevent the bullet from damaging the Enemy itself. You might also want to raise the AI script a little bit to shoot bullets in another position or, better, add a shootPoint transform field and create an empty Object in the Enemy to use as a spawn position. If you do that, consider making the empty Object to not...
