Do we also learn to make a game step by step, or is just book just information of all the tools that Stencyl uses?
It's not really a template book. It's not a book about making "Flappy Bird" or "Angry Birds" or whatever popular bird game is on the iTunes App Store lately. That's because I felt that wouldn't be true learning. I didn't want people just copying the templates and not really learning much more than that.
So instead, the book focuses more on making those confusing blocks (like cos/sin or lists) more interesting and useful.
Early on, a character called "Picopede" is introduced. Throughout the book, he grows. There's enough information in the book to show how to move the actor (in many different ways), display health (classic video game style), work with collision shapes, working with scenes, working with attributes, working with other actors, using events to control many actors at once, display high scores.
The book is very linear. With these basic pieces, the book does show how to create a game. However, it's up to the reader to put those pieces in the proper order for the game that they want to make.
