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.

Creating fluid simulations

As we said, the best way to learn how to create particle systems is to keep looking for already-created particle systems and explore how people have used the various system settings to create completely different simulations.

In this section, we will see how to create the following effects using particle systems:

  • A waterfall effect
  • A bonfire effect

Let's start with the simplest one, the waterfall effect.

Creating a waterfall effect

In order to do this, follow these steps:

  1. Create a new particle system (GameObject | Effects | Particle System).
  2. Set Shape to Edge and its Radius to 5 in the Shape module. This will make the particles spawn along a line of emission:

  3. Set the Rate over Lifetime of the Emission module to 50.
  4. Set the Start Size of the Main module to 3 and the Start Lifetime to 3:

  5. Set the Gravity Modifier of the Main module...
