Overview of this book

Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects. Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt. By the end of this book, you'll have created an application that has been tested and is ready to be shipped.

Preparing the board game

Even if our game has a 3D representation, we will implement 2D gameplay like the original snake game. Our game items are born, will live, and die in a 2D area. Like chess, this board will be composed of rows and columns. But in our snake game, each square can be:

  • An apple
  • A snake
  • A wall
  • Empty

Here is an example of a board representation from the point of view of the engine:

This is a small 10x8 board; even if size does not matter, you will be able to define a bigger one. Your game, your rules! We have walls (W) surrounding the game area. An apple (A) is spawned at (7; 2). Finally, we have a snake (S) beginning at (3; 4) and ending at (5; 5).

It is time to create our board class. Please create a JS file called board.js:

function Board(columnCount, rowCount, blockSize) { 
    this.columnCount = columnCount; 
    this.rowCount = rowCount;
