Game Programming Using Qt: Beginner's Guide

By: Lorenz Haas, Witold Wysota, Witold Wysota, Lorenz Haas

Overview of this book

Qt is the leading cross-platform toolkit for all significant desktop, mobile, and embedded platforms and is becoming more popular by the day, especially on mobile and embedded devices. Despite its simplicity, it's a powerful tool that perfectly fits game developers’ needs. Using Qt and Qt Quick, it is easy to build fun games or shiny user interfaces. You only need to create your game once and deploy it on all major platforms like iOS, Android, and WinRT without changing a single source file. The book begins with a brief introduction to creating an application and preparing a working environment for both desktop and mobile platforms. It then dives deeper into the basics of creating graphical interfaces and Qt core concepts of data processing and display before you try creating a game. As you progress through the chapters, you’ll learn to enrich your games by implementing network connectivity and employing scripting. We then delve into Qt Quick, OpenGL, and various other tools to add game logic, design animation, add game physics, and build astonishing UI for the games. Towards the final chapters, you’ll learn to exploit mobile device features such as accelerators and sensors to build engaging user experiences. If you are planning to learn about Qt and its associated toolsets to build apps and games, this book is a must have.

Qt Quick and C++

Thus far, we have been using standard Qt Quick items or creating new ones by compositing existing element types in QML. But there is a lot more you can do if you interface QML and C++ using the technologies Qt has to offer. Essentially, QML runtime does not differ much in its design from Qt Script, which you read about in the previous chapter of this book. In the following paragraphs, you will learn how to gain access to objects living in one of the environments from within the other one, as well as how to extend QML with new modules and elements.

Until now, all the example projects we did in this chapter were written with just QML and because of that, the project type we were choosing was Qt Quick UI, which let us quickly see the Qt Quick scene we modeled by interpreting it with the qmlscene tool. Now, we will want to add C++ to the equation and since C++ is a compiled language, we will need to do some proper compilation to get things working. Therefore, we will be using...
