5.0 étoiles sur 5Nice intro into the + and - of Java as a game language7 février 2005

Be careful of your expectations here. This is NOT a 'how to' book with 100+s pages of code samples. This is not a book in the 'java cookbook' series.
What this IS is a book that describes the +/- of the java language and the JVM and talks about PERFORMANCE issues extensively. The author goes out of his way to talk about the issues surrounding the use of Hotspot VM/JIT and benchmarks with math/IO, etc.
The last 1/2 of the book (maybe less) deals with some high-level understanding of rendering and collision detection.
Topics include bindings to OpenGL (jogl), JNI (it's cost vs. benefits in it's use), performance of java.math and where it can be optimized, some simple treatment of sockets vs. datagram/multicast sockets, audio integration, proper use and performance with direct bytebuffers vs. java arrays (java.io/java.nio), also a little on GC collection algorithms. Also a treatment of java's +/- as a scripting language, as well as a good look at rendering and collisions.
Overall a very interesting techical look at the VM and performance challenges that java as a GAME language faces.
The author makes it clear that good java games can be written but good PERFORMANCE games takes an understanding of the JVM and proper code architecture that takes into account java's strengths (as oppsed to it's weaknesses).
I would recommend this a a great starting point for someone interested in making good java games or just learning about java performance issues. If you want a 'cookbook' you'll need to look elsewhere.

2.0 étoiles sur 5Disappointing29 juillet 2004
Par A.Jobes - Publié sur Amazon.com
I have been waiting for this book for a while as the publishing date slipped a few times. Having recieved the book, I wish I never bought it. To start with 2/3 of the book is about java, optimisation, a poor section on JDBC and some networking stuff that you can find anywhere else. The remaining of the book is a general discussion of Java and the last chapter (Ch 15) is about a simple 3d engine (jist 3D)which is pretty incomplete. The book has many incomplete code snippets and no games in sight which is surprising when the authors have been around the game development forums for such a long time.
The book seems to be a poor attempt in discussing games development in Java. More like an attempt to cash in the market demand.
If you are buying this book to learn about Java and 3D, then there are better books such as -Developing Games in Java- by Brackeen which has good explanations about various aspect of game development in java.
My advice is that dont waste your money on this book!

This appears to have been written by a Java evangelist who loves to talk shop about the ins & outs of Java programming. Unfortunately, this is supposed to be about game programming, and in that regard, I found nothing practical about it. A single chapter on 2D graphics? This book goes into great depth providing the mathematics of 3D collision detection (chapter 16), but doesn't get any further in the graphics department than drawing a few static (non-animated) Actors (i.e. "sprites").
The focus of this book is off-point from the start, in my opinion. The chapters toward the end on 3D graphics provide insufficient information to build a 3D game, and yet the material up to that point is insufficient to build a 2D game. What you end up with in the end is a lot of knowledge about Java, but not a single practical program, let alone game.
This problem is exacerbated by the fact that the CD includes .java and .class files, but no explanation on what to do with them (the back cover does say this is a Beginning-Intermediate book, not Advanced).
The Java Developer's Kit comes with much better demos than you will find in this book WITH convenient .html files with code to run the applets, which is something these authors should have included.

4.0 étoiles sur 5A good starting point for game development11 mars 2005
Par John117 - Publié sur Amazon.com
Hi. First off, id like to state that I am by no means a professional programmer. I am a high school junior, who is currently working through AP computer science. I picked this book up on a trip as reading material, and it has been very informative. The code samples are extremely well written, and easy for me to follow. My only major critisim is that the printed code samples have several typos in them, but if you look through the code included on the cd, then you'll have no problems. Overall, I thought it was well worth the $36.00 I paid for it.

3.0 étoiles sur 5Interesting but flawed24 octobre 2005
Par John F. Wright - Publié sur Amazon.com
Overall I find this a good book. It has interesting discussion and introduction of several topics that interest me. However it is flawed with typos and misstatements (sometimes contradicted in the next sentence). It's also fairly out of date now (JDK 1.5 comments are somewhat out of date now and JOAL comments are a bit out of date).
Pick it up at a bargain price (under $5) and I do recommend it as a good book on JOAL and several other topics of value for Java programming (not just games).
