Game Programming Using Qt: Beginner's Guide

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 – developing the game architecture


Create a new Qt Widgets Application project. After the project infrastructure is ready, choose New File or Project from the File menu and choose to create a C++ Class. Call the new class ChessBoard and set QObject as its base class. Repeat the process to create a GameAlgorithm class derived from QObject and another one called ChessView but, this time, choose QWidget as the base class. You should end up with a file named main.cpp and four classes—MainWindow, ChessView, ChessBoard, and ChessAlgorithm.

Now navigate to the header file for ChessAlgorithm and add the following methods to the class:

public:
  ChessBoard* board() const;
public slots:
  virtual void newGame();
signals:
  void boardChanged(ChessBoard*);
protected:
  virtual void setupBoard();
  void setBoard(ChessBoard *board);

Also, add a private m_board field of type ChessBoard*. Remember to either include chessboard.h or forward-declare the ChessBoard class. Implement board() as...
