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.

Quick game programming


Here, we will go through the process of creating a platform game using Qt Quick. It will be a game similar to Benjamin the Elephant from Chapter 6, Graphics View. The player will control a character that will be walking through the landscape and collecting coins. The coins will randomly be appearing in the world. The character can access highly placed coins by jumping. The more the character jumps, the more tired he gets and the slower he begins to move and has to rest to regain speed. To make the game more difficult, at times moving obstacles will be generated. When the character bumps into any of them, he gets more and more tired. When the fatigue exceeds a certain level, the character dies and the game ends.

Throughout this chapter as well as the previous one, we prepared a number of pieces we will be reusing for this game. The layered scene that was arranged when you learned about animations will serve as our game scene. The animated sun is going to represent the...
