Building a Simple Game with Qt’s QCanvas
A DIFFERENT CANVAS
The Qt toolkit from Trolltech sports features that appeal to any developer’s needs, but one of the most fascinating and powerful parts of the toolkit is the QCanvas class.
QCanvas is a very versatile widget that lets you add high performance 2D graphics to a Qt application. With features such as collision detection and sprite support, QCanvas is very much suited to 2D games. But QCanvas has also been used in diverse applications such as KTurtle, a logo interpreter. In this article, I will show you how to build a very simple game using QCanvas components. The example game I’ll discuss in this article, which I call Bricks, consists of a rectangular play area containing several rectangular objects. The rectangular objects are the bricks. A ball bounces around in the play area. If the ball strikes a brick, the brick disappears. A paddle, operated by the user, demonstrates how you can integrate user interaction into the game. To keep the game as simple as possible, the ball cannot leave the play area.
