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.

Time for action – setting up the server

A look at the server's GUI shows us that it principally consists of QPlainTextEdit (ui->log) that is used to display system messages and a button (ui->disconnectClients), which allows us to disconnect all the current connected clients. On top, next to the button, the server's address and port are displayed (ui->address and ui->port). After setting up the user interface in the constructor of the server's class TcpServer, we initiate the internally used QTcpServer, which is stored in the m_server private member variable:

if (!m_server->listen(QHostAddress::LocalHost, 52693)) {
  ui->log->setPlainText("Failure while starting server: "
                        + m_server->errorString());
connect(m_server, SIGNAL(newConnection()),
        this, SLOT(newConnection()));

What just happened?

With QTcpServer::listen(), we defined that the server should listen to the localhost and the 52693 port for new incoming connections....
