Greenfoot Online
New developments have been happening in the world of Greenfoot. First it got sound, and now it has the ability to export projects as a Java applet on it's own little web page. Here are a few of mine I've been working on over the last few months, and so this is a bit of an experiment. I only got the latest version of Greenfoot an hour and a half ago, so you'll be testing this for me.

First is PacMan Be careful when clicking on the link, the sounds are too loud. But I felt it was a very good rendition. Like all Greenfoot projects you can move stuff around with the mouse allowing you to cheat regularly.

Next is Simon Lights light up, you gotta press the corresponding key button (1, 2, 3 and 4) in the correct order. If your right, the order gets longer. If your wrong, you loose.

Finally is New York Bagle Delivery. I was asked to make something like worms, but not to make all violent games where everything explodes. This is the result. I feel it needs more work in terms of an ending, but it helps to show some of the capabilities of Greenfoot (the wind animation took ages).

Enjoy!

|edit| The site the applet's were stored is no longer up, so the links have been removed. If your really interested in playing them, e-mail of PM me. |edit|

 		I had to download plugins. Firefox spend about 10 minutes looking for them without success until I got bored of waiting. I'll try again tomorrow, hopefully I'll have better luck then.

 		I don't understand why your all getting these problems. Especially since for some it works perfectly.

Steve, what so you think?

 		I'm guessing it's a security issue ie. unsigned applets?
*shrugs*
Will try again later.

 		I tried showing a different Java applet to someone I know and he had the Java service in IE 7 disabled, and he said he never enabled or disabled it. So maybe with IE 7 it is disabled by default. Are people using IE 7?

 		Someone has suggested to me that the problem may lie with the fact I used Java 6 to compile the applet (which might be installed on my brothers pc) and that it is not fully backwards compatible.

I find this hard to believe, but plausible.

 		I just updated JSE 1.5.0_10 to 1.6.0 and they work fine now

 		So that is the problem. This is an important issue, as Greenfoot and BlueJ (like a lot of applications) require Java 6 to run on Vista (although I'm pretty sure that's only for the native windows look and feel).

So, upgrade to Java 6 to play my games!
