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.

OpenGL


We are not experts on OpenGL, so in this part of the chapter we will not teach you to do any fancy stuff with OpenGL and Qt but rather will show you how to enable the use of your OpenGL skills in Qt applications. There are a lot of tutorials and courses on OpenGL out there so if you're not that skilled with OpenGL, you can still benefit from what is described here by employing the knowledge gained here to more easily learn fancy stuff. You can use external materials and a high-level API offered by Qt, which is going to speed up many of the tasks described in the tutorials.

Introduction to OpenGL with Qt

There are basically two ways you can use OpenGL in Qt. The first approach is to use QOpenGLWidget. This is mostly useful if your application heavily depends on other widgets (for example. the 3D view is only one of the views in your application and is controlled using a bunch of other widgets surrounding the main view). The other way is to use QOpenGLWindow; this is most useful when...
