I own both editions of this book, but only started working through the second edition (since it is more up to date and more relevant since Unity 5.5 came out). Do you know if there is a forum for the second edition book where questions can be asked? I find some of the instructions and assignments making very little sense if any. I also ran into issues when constructing the UI and I wanted to discuss these with the author, but without a forum or at least an e-mail address, this gets challenging.
Have you read this second edition of the book? What do you think of it?
