5.0 out of 5 stars
Nice intro into the + and - of Java as a game language, February 7, 2005
This review is from: Practical Java Game Programming (Charles River Media Game Development) (Paperback)
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.

Disappointing, July 29, 2004
This review is from: Practical Java Game Programming (Charles River Media Game Development) (Paperback)
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!

Beats a trail around the camp fire without ever cooking anything, December 4, 2005
This review is from: Practical Java Game Programming (Charles River Media Game Development) (Paperback)
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.
