Game Programming Using Qt: Beginner's Guide

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.

In this chapter, you learned how to create simple graphical user interfaces with Qt. We went through two approaches—creating user interface classes by writing all the code directly and designing the user interface with a graphical tool that generates most of the code for us. There is no telling which of the two approaches is better; each of them is better in some areas and worse in others. In general, you should prefer using Qt Designer forms to write code directly because it's faster and less prone to errors as most of the code is generated. However, if you want to retain more control over the code or your GUI is highly dynamic, writing all the code yourself will be easier, especially when you gain enough experience with Qt to avoid common pitfalls and learn to use advanced programming constructs.

We also learned how the heart of Qt—the meta-object system—works. You should now be able to create simple user interfaces and fill them with logic by connecting signals to slots—predefined...
