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

Implementing movement

Almost every object in the game moves one way or another, the Player character with the keyboard, the Enemies through AI, the bullets simply move forward, and so on. There are several ways of moving objects in Unity, so we will start with the simplest one, that is, through the Transform component.

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

  • Moving objects through Transform
  • Using Input
  • Understanding Delta Time

First, we will explore how to access the Transform component in our script to drive the Player movement, to later apply movement based on the Player's keyboard Input. Finally, we are going to explore the concept of Delta Time to make sure the movement speeds are consistent in every computer. We are going to start learning about the Transform API to master simple movement.

Moving objects through Transform

Transform is the component that holds the Translation, Rotation, and Scale of an object, so every...
