Working with the latest technologies is always fun and with a rapidly growing mobile market, it is a new and exciting place to be."Learn HTML5 by Creating Fun Games" takes you through the journey of learning HTML5 right from setting up the environment to creating fully-functional games. It will help you explore the basics while you work through the whole book with the completion of each game."Learn HTML5 by Creating Fun Games" takes a very friendly approach to teaching fun, silly games for the purpose of giving you a thorough grounding in HTML5. The book has only as much theory as it has to, often in tip boxes, with most of the information explaining how to create HTML5 canvas games. You will be assisted with lots of simple steps with screenshots building towards silly but addictive games.The book introduces you to HTML5 by helping you understand the setup and the underlying environment. As you start building your first game that is a typography game, you understand the significance of elements used in game development such as input types, web forms, and so on.We will see how to write a modern browser-compatible code while creating a basic Jelly Wobbling Game. Each game introduces you to an advanced topic such as vector graphics, native audio manipulation, and dragging-and-dropping.
