Open Source Java Game Utilities: LWJGL 0.98 and Game Gardens

by Drew Falkman

I don't know about you, but when I was a kid and first learning how to program, there was only one reason: games. In my mind that was the pinnacle—there was no higher pursuit in the world of programming. I wanted to make games. I started out making those text-based games, then evolved into some graphical stuff, but since it was the Apple II (yes, I'm dating myself now) there just wasn't that much to do. Now that I'm grown up and it's 2005, games are serious. And it's not Apple Basic anymore, we've got Java. This month, I decided to indulge my inner child and see what was available in the open source world for game libraries. I found a couple worth mentioning.

Introduction

• The Lightweight Java Game Library (LWJGL) is a robust suite of tools to aid in the development of professional games—in Java, of course.
• Game Gardens is an API that enables the development of networked games. It enables multi-player environments so you can beat your faraway friends at cards or kill them dead.

Warning: LWGL won't necessarily make game development any easier. However, it will likely improve the quality of the games you develop. It provides access to resources that the standard Java Software Development Kit (SDK) does not handle so well. A look at the LWGL mission will show you what this is about: speed, device utilization (e.g. cell phones to multi-CPU boxes), and simplicity. A look at the projects using LWJGL shows how this is paying off. These games are cool and varied.

The API is a little murky. In order to get started with LWJGL, you will have to be familiar with OpenAL and OpenGL and also with 3D models, input control, and so on. In short, you have to learn how to develop games first. But LWGL is giving Java programmers a shot at developing professional quality games. One other note: LWGL will not work with applets—you'll need to run it using their JVM or using the Java Web Start tool.
