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.

Since we discussed QNetworkAccessManager, you now have the knowledge you need to integrate Facebook, Twitter, or similar sites into your application. They all use the HTTP protocol and simple requests in order to retrieve data from them. For Facebook, you have to use the so-called Graph API. It describes which interfaces are available and what options they offer. If you want to search for users who are called "Helena", you have to request https://graph.facebook.com/search?q=helena&type=user. Of course, you can do this with QNetworkManager. You will find more information about the possible requests to Facebook at http://developers.facebook.com/docs/graph-api.

If you wish to display tweets in your game, you have to use Twitter's REST or Search API. Assuming that you know the ID of a tweet you would like to display, then you can get it through https://api.twitter.com/1.1/statuses/show.json?id=12345, where 12345 is the actual ID for the tweet...
