Overview of this book

Qt 5.7 is an application development framework that provides a great user experience and develops full-capability applications with Qt Widgets, QML, and even Qt 3D. This book will address challenges in successfully developing cross-platform applications with the Qt framework. Cross-platform development needs a well-organized project. Using this book, you will have a better understanding of the Qt framework and the tools to resolve serious issues such as linking, debugging, and multithreading. Your journey will start with the new Qt 5 features. Then you will explore different platforms and learn to tame them. Every chapter along the way is a logical step that you must take to master Qt. The journey will end in an application that has been tested and is ready to be shipped.

Preface

Creating an entry point for your Qt3D code


For those who did not play the snake game in their youth, here is a quick reminder of the gameplay:

  • You control a snake moving in an empty area

  • This area is surrounded by walls

  • An apple spawns randomly in the game area

  • If the snake eats the apple, it 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

We will keep the 2D feel of the original snake game by placing the camera above the game area but we will spice things up with 3D models and some shaders...
