Video: Update Space Invaders Game While Playing It

  • submit to reddit


In this video, Allan Gregersen from the University of Southern Denmark shows a space invaders game written for the Java desktop. As he plays the game, he enhances it with new features. How? Via his "Javeleon" (Java chameleon), which enables you to change and extend Java desktop applications via dynamic updates to existing features. Read an interview with Allan all about Javeleon here.

Also seen in the video is Fabrizio Giudici, NetBeans Dream Team member, programmer, blogger, and conference speaker. The above video can also be viewed here on YouTube and here on

NetBeans has been missing a space invaders plugin for years. Any way to get that integrated in the IDE anytime soon? Please, please...

IMHO, is is definitely worthwhile to propose a game distribution on top of NetBeans.

See my post Why not a game distribution on top of NetBeans or Eclipse ?


It would help the NetBeans platform to gain traction (to gain full traction, imho, it would be nice to provide such a distribution, or to host a dedicated update center).

It's by no means a finished game. Have fun!

 "Javeleon"... I like the name, it has a nice ring to it. What Allan does is pretty awesome, I had no idea you had such smart digital accomplices, I didn't know you could even do such a thing. Perhaps if I could modify games while playing them, I would have more awesome friends, as well...
