Game Programming Using Qt: Beginner's Guide

By: 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.

Chapter 7. Networking

In this chapter, you will be taught how to communicate with the Internet servers and with sockets in general. First, we will have a look at QNetworkAccessManager, which makes sending network requests and receiving replies really easy. Building on this basic knowledge, we are then going to use Google's Distance API to get information about the distance between two locations and how long it would take to get from one to the other. This technique and the respective knowledge can also be used to include Facebook or Twitter in your application via their respective APIs. Then, we will have a look at Qt's Bearer API, which provides information on a device's connectivity state. In the last section, you will learn how to use sockets to create your own server and clients using TCP or UDP as the network protocol.
