Game Programming using Qt 5 Beginner's Guide - Second Edition

Overview of this book

Qt is the leading cross-platform toolkit for all significant desktop, mobile, and embedded platforms and is becoming popular by the day, especially on mobile and embedded devices. It's a powerful tool that perfectly fits the needs of game developers. This book will help you learn the basics of Qt and will equip you with the necessary toolsets to build apps and games. The book begins by how to create an application and prepare a working environment for both desktop and mobile platforms. You will learn how to use built-in Qt widgets and Form Editor to create a GUI application and then learn the basics of creating graphical interfaces and Qt's core concepts. Further, you'll learn to enrich your games by implementing network connectivity and employing scripting. You will learn about Qt's capabilities for handling strings and files, data storage, and serialization. Moving on, you will learn about the new Qt Gamepad module and how to add it in your game and then delve into OpenGL and Vulcan, and how it can be used in Qt applications to implement hardware-accelerated 2D and 3D graphics. You will then explore various facets of Qt Quick: how it can be used in games to add game logic, add game physics, and build astonishing UIs for your games. By the end of this book, you will have developed the skillset to develop interesting games with Qt.

3D Graphics with Qt

Many modern games take place in 3D worlds. Graphics processing units are constantly evolving, allowing developers to create more and more visually appealing and detailed worlds. While you can use OpenGL or Vulkan directly to render 3D objects, this can prove to be quite challenging. Luckily, the Qt 3D module provides an implementation of 3D rendering with a high-level API. In this chapter, we'll learn to use its capabilities and see how we can create a 3D game with Qt.

Qt 3D is not limited to rendering. You'll also learn to handle user input and implement game logic in a 3D game. Qt 3D was designed to be highly efficient and fully extensible, so it allows you to implement your own additions to all Qt 3D systems.

Qt 3D offers both C++ and QML API with mostly equivalent functionality. While the C++ API allows you to modify and extend the implementation...
