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.

Qt Quick and C++

While QML has a lot of built-in functionality available, it will almost never be enough. When you're developing a real application, it always needs some unique functionality that is not available in QML modules provided by Qt. The C++ Qt classes are much more powerful, and third-party C++ libraries are also always an option. However, the C++ world is separated from our QML application by the restrictions of QML engine. Let's break that boundary right away.

Accessing C++ objects from QML

Let's say that we want to perform a heavy calculation in C++ and access it from our QML calculator. We will choose factorial for this project.

The QML engine is really fast, so you can most likely calculate factorials...
