Not related to Java, but this is a very cool demo: http://browserquest.mozilla.org/
Even better, the source is at github, and is a good example of using nodejs to do the server work. https://github.com/mozilla/BrowserQuest
Here’s Mozilla’s own writeup: https://hacks.mozilla.org/2012/03/browserquest/
Seems interesting. However it loads forever here asking your name.
Lots of clipping problems (cut off sprites) when I finally see ‘the world’. I can’t do anything: it’s not responding to any input.
Using Chrome, obviously. :persecutioncomplex:
Dont mention chrome, I even have problem with my FF10 
Why obviously? Chrome is google, not Mozilla
Runs really well for me, using Chrome on Windows 7.
Quite fun 
Yes, indeed, not it’s working:)
Works totally okay, looks really nice no clipping problem and yes I use mozialla (mostly because it comes from mozilla :o)
Made better progress, now I can input my name. But the game keep trying connect to server…
someone want to port it to Java? libgdx + html5 backend maybe? 
Guess you shouldn’t ask volunteer first, but chit chat to mozilla before about permission?
Nice game.
After some quests I unfortunately got stuck exactly at the levelboarder while fighting.
Good. Let someone make it so I can play the game. HTML5 doesnt work here.
Runescape is better. This “game” is fine but extremely rudimentary, it doesn’t prove HTML 5 is a good choice for the creation of MMORPG.
What are you talking about? This game is a great example, it proves smooth animations, sounds, networking, and almost any game can be using HTML5.
Calling BrowserQuest a “MMO” is a little tongue-in-cheek. I suspect Runescape had just a scooch more development time and resources put into it.
Networking? NO! I can’t still play it.
Apart from the HTML5 tech, its a nice casual design of a “coffee break MMO”.
As most action are automized and point-click without fizzeling with the inventory or stats.
Beeing so simple its very easy to get into.
Cute game, all 20 achievements!
