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.

Chapter 5. Graphics with Qt

When it comes to graphics, we have so far been using only ready-made widgets for the user interface, which resulted in the crude approach of using buttons for a tic-tac-toe game. In this chapter, you will learn about much of what Qt has to offer with regard to custom graphics. This will let you not only create your own widgets, incorporating content that is entirely customized, but also integrate multimedia in your programs. You will also learn about employing your OpenGL skills to display fast 3D graphics. If you are not familiar with OpenGL, this chapter should give you a kick-start for further research in this topic. By the end of the chapter, you will be able to create 2D and 3D graphics for your games using classes offered by Qt and integrate them with the rest of the user interface.

When it comes to graphics, Qt splits this domain into two separate parts. One of them is raster graphics (used by widgets, for example). This part focuses on using high-level...
