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 – connecting the game algorithm

It would take us too long to implement a full chess game algorithm here, so we will instead settle for a much simpler game called Fox and Hounds. One of the players has four pawns (hounds) which can only move over black fields and the pawn can only move in a forward fashion (toward higher ranks). The other player has just a single pawn (fox) which starts from the opposite side of the board.

It can also move only over black fields; however it can move both forwards (toward higher ranks) as well as backwards (toward lower ranks). Players move in turns by moving their pawn by to a neighboring black field. The goal of the fox is to reach the opposite end of the board; the goal of the hounds is to trap the fox so that it can't make a move.

Time to get to work! First we will extend the ChessAlgorithm class with the required interface:

class ChessAlgorithm : public QObject
  Q_ENUMS(Result Player)
  Q_PROPERTY(Result result READ result...
