First a disclaimer, I'm a Professional Software Engineer with a Masters degree and many languages in my toolkit so my qualms with this book are a little nitpicky and I'm looking at it from a "get you up to speed fast" perspective. Your mileage may vary.

This book is a really good introduction, not only to Lua but to programming in general. So far, the information has been spot-on and the author makes a very thoughtful effort at presenting a broad, balanced, and easy to follow take on building Lua/XML addons for WoW. I found it an enjoyable read and am now actively using it

Now with all that said, there are a few deficiencies:
- There are a lot of copy-and-paste mistakes in the API documentation (identical descriptions for very different methods/types)
- There are editing mistakes and typos littered throughout the book
- If you don't like poker or are new to WoW a lot of the examples and project sections are hard to follow. (The book used Texas Hold-em as a recurring and pervasive example of how to use most of the WoW constructs. Many of the other examples depend on the reader being a relatively experienced WoW player and rely on Jargon and advanced situations to explain the usages of some tools).
- I found the treatment of the display capabilities of the API somewhat lacking. I would have loved an example of rendering 3D models in a frame.
- One extremely useful addition would have been a description of each part of the native interface including class descriptions beyond the advice to read the native UI source code. (Several specific objects are referenced, but not in one place or in any complete way)
- Almost all of the tools suggested in the early chapters are Windows-specific (and as I have a Mac, they weren't as useful). Most gamers won't be bothered by this

Again, I'll reiterate that this is a very good book and I will recommend it to anyone who asks. I just hope for a second edition with some more content.

I'm not quite sure where to start on a review like this, so I'll just skip to the end: if you are seriously thinking of writing WoW add-ons, then make sure you read this book! Now that I've got that out of the way, let me go back and explain why.

There are three primary reasons why I would recommend this book to someone. First, the author of this book created Deadly Boss Mods, one of the most popular (and indispensable) add-ons available, which means that the knowledge he shares comes from experience. That experience comes in handy for navigating around those "gotchas" that have crept into the API over time. Second, the technical information he provides is both thorough and presented in an way that helps you understand the "why" and "how" of add-on development. For instance, the author waits until the end of the book to explain macros. This might seem a bit backwards until you read the rest of the book and realize just how much you need to know to make the most of the macro system. Third, this book is an excellent introduction to Lua, the scripting language used in WoW add-ons. The book provides a thorough understanding of Lua, meaning that the information you learn for writing WoW add-ons will be just as useful when you decide to write Lua-based add-ons for other applications (or when you just want to use Lua on its own).

Now, there were a few things about the book that I initially didn't like. First, the book is written in an informal, somewhat conversational style. As a result, I thought this was going to be a "For Dummies" type of book. After a few chapters, it becomes clear that this book is definitely not for dummies and the relaxed style ends up making the information very accessible. Second, one of the larger add-ons that the author builds is a "Texas Hold-Em" client/server. Since I had no intention of writing this kind of add-on (and Texas Hold-Em is a little dated), I thought I was in for several chapters of useless information. Again, after reading just a small way into that section, it became clear that the internal workings of the add-on apply to all large, multi-user add-ons. The "hold-em" part of the add-on ends up being entirely secondary. Do not skip over this add-on!

So if, after all of this, you are still thinking to yourself that you can just read some online resources, dissect a few existing mods, then sit down and write your own, think again. Source code will not provide the knowledge you need to write high-quality, professional mods. This book provides that knowledge.

Finding any type of LUA information for World of Warcraft is difficult to say the least. This author has several examples with line by line explanations for the code through the book. I have found it to be invaluable to have as a quick reference for various tasks.

On the same note, I was stuck on a problem with my own mod, trying to model it around some code that is exampled in the book, and after struggling with it for a while I finally broke down and e-mailed the author a question, and not only did he respond lightning fast to my question, but he even included several code snipits he wrote on the fly to show me ways to solve my problem.

I continually refer back to this book whenever I have questions about how to accomplish something in WoW LUA Mods.

"Beginning Lua with World of Warcraft Add-ons" is one of the latest books detailing the design and implementation of user-interface add-ons for the popular MMORPG, World of Warcraft. As this book is written by the same individual that wrote the bulk of the powerful raid add-on, "Deadly Boss Mods," one would expect the author to be well-versed in Lua scripting. In this regard, the book doesn't disappoint. Although the examples could be more focused on WoW game-play (a large portion of development examples in the book deal with implementing a poker game in WoW), the book teaches the reader the paradigms and intricacies of writing Lua for WoW. Unfortunately, since the book is a printed work, it runs the risk of getting outdated as the API for WoW is constantly evolving. That being said, I would recommend this book to anyone who would like to learn to create an add-on for WoW.

I really enjoyed this book, it covers almost all you need to know about lua language and in meanwhile you learn how to make nice Wow addons. Highly recommended.

Before buying this book I would have liked to know the following:

-WoW addon libraries have very little documentation and code samples.
-WoW addon coding doesn't have a dedicated development environment.
-Lua is a very detailed and powerful programming language not just for addons.
-The book has some syntax errors in the sample code.
-The book is too wordy when explaining things, pictures would be appreciated.

Blizzard only publishes the addon library. They do not support or document it. You won't find a reference with code examples, usages, or anything else useful.

When coding your addons, the book says you should use the Lua compiler. That's great if your coding a dedicated Lua program but when your using WoW addon libraries the compiler will say it doesn't understand some of your code. The other option is to use some Lua addons that work in game and allow you to run and test your code. These are your best bet.

Lua is not just a WoW addon programming language. You can actually make a pretty good career using this stuff. But if your new to Lua or programming for that matter, your twice as deep in the hole. Lua is the language used for addons but it also has its conventions, syntax, and schema. My advice is to learn the intricacies of Lua before trying to program addons. You don't need this book to do that. Lua is free and open source language.

In the early chapters, I found the code examples would not return the intended results. When I went to the website for the book, I found the code examples had errors.

The book says Beginning Lua with WoW addons. At first it sounds like the book will teach you Lua using WoW as a guide. There is only one lengthy and wordy chapter on Lua, and the rest is WoW related after that. In explaining common programming principles such as events and triggers, the author could have used a picture or at least better examples. It all gets too confusing after a while and you find yourself lost.

I would recommend this book if you already are familiar with Lua and are ok with how to develop WoW addons. I'm sure the author is extremely talented and bright but this book fails to get his message across coherently.

I bought this because the general introduction to Lua was the clearest I've found anywhere. Most introductions are based upon the great and freely available formal description of the language rather than addressing the language from the non-Lua programmer's perspective.

This book had the basics of Lua from the perspective of both a non-programmer and programmer from another language. I come from C/C++ and was glad to learn the little quirks that make Lua different from other languages. The author quickly takes you through all the incorrect assumptions you may bring with you from other languages, the neat new things that Lua offers, and sets off into the WoW API and its event driven architecture.

The thing that I liked best was his explanation of best practices. His coding is masterful, so when he "recommends" doing something a certain way, just do it that way. Of course the new patch complicates things, but if you're gonna be writing an Addon, you should be able to handle adapting to some changes in the API and events.

I started writing some Add-ons for WoW a while back (during the first release of the game). Having this book would have helped bring me much further along, much faster and alieviated a lot of my issues that I had back then. The book is a great reference for when you are trying something that you haven't done before and need a few snippets of code to help you along. If you are just starting writing add-ons or UI's for World of Warcraft then you really need to read this book, or have it in your library to refer to when you have a few issues with something (which you will!)

I ordered this product on Dezember 18, today is February 14 and i didnt recievied the product!
