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.

Now, we will use Qt Designer forms to build a simple game configuration dialog that will let us choose names for our players.

In the window that appears, choose Dialog with Buttons Bottom:

Adjust the class name to ConfigurationDialog, leave the rest of the settings at their default values, and complete the wizard.

Drag and drop two labels and two line edits on the form, position them roughly in a grid, double-click on each of the labels, and adjust their captions to receive a result similar to the following figure:

Select the first line to edit and look at the property editor. Find a property called objectName and change it to player1Name. Do the same for the other line and call it player2Name. Then, click on some empty space in the form and choose the Layout in a grid entry in the upper toolbar. You should...
