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.

Data storage


When implementing games, you will often have to work with persistent data—you will need to store the saved game data, load maps, and so on. For that, you have to learn about the mechanisms that let you use the data stored on digital media.

Files and devices

The most basic and low-level mechanism that is used to access data is to save and load it from the files. While you can use the classic file access approaches provided by C and C++, such as stdio or iostream, Qt provides its own wrapper over the file abstraction that hides platform-dependent details and provides a clean API that works across all platforms in a uniform manner.

The two basic classes that you will work with when using files are QDir and QFile. The former represents the contents of a directory, lets you traverse filesystems, creates and remove directories, and finally, access all files in a particular directory.

Traversing directories

Traversing directories with QDir is really easy. The first thing to do is to have...
