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.

  • This area is surrounded by walls.
  • An apple spawns randomly in the game area.
  • If the snake eats the apple, the snake grows and you gain a point. Right after, another apple spawns in the game area.
  • If the snake touches a wall or a part of its own body, you lose.

The goal is to eat as many apples as possible to have the highest score. The longer the snake, the harder it will become to avoid the wall and its own tail. Oh, and the snake goes faster and faster each time it eats an apple. The architecture of the game will be the following:

  • All the game items will be defined using Qt3D in QML
  • All the game logic will be done in JavaScript, which will communicate with the QML elements
