If my Linode falls over while hosting this, or you want to download all the files and host them locally to play with it, I've put a ZIP file of the demo up on my dropbox here: http://dl.dropbox.com/u/1643240/Platformer.zip

Please note that it won't work if loaded from file:// because Firefox and Chrome are really aggressive about cross-origin checks (I think IE9 and IE10 will load it just fine from disk, though).

Questions and comments highly welcomed. :) The compiler is still relatively immature, but I'm very optimistic about where I can take it in the future.

Really nice...

I found it interesting that you are with Mozilla considering the guy behind the llvm-to-javascript compiler works there too...

Yeah, Azakai's brilliant. The paper he published was useful when figuring out how to translate goto statements to JS (C# supports them, though thankfully, they aren't used much.)

Holy crap, that was awesome!

Nice! I've always thought emscripten is a bit annoying, as it doesn't integrate with the LLVM infrastructure, but instead re-parses everything in Python...

This is pretty impressive. Are the any details on the C#->Javascript compiler?

Any comments about Ray Cromwell's comments on the lack of suitable sound APIs for games in HTML? http://cromwellian.blogspot.com/2011/05/ive-been-having-twit...

Very, very cool. Interested to see how System.Threading is implemented/converted.

It's not. It might be possible to implement it in the future with Web Workers, but it'd be a stripped down implementation.

You could certainly run the managed bits of System.Threading through the translator, though; I've done that before. But the shiny bits happen to live on the native side of things, in both MS's CLR and Mono... :(

Gotcha, looking at the JS. Still very impressive. Been interested in the Script# project for awhile, this looks along same lines. Good stuff.

I created an account just to upvote this, very cool and keep up the good work! :)

Me too haha =)

Worked on OSX just fine w/ FF4. Great job so far! Can't wait to checkout and play with it on a Windows box later.

This worked surprisingly well. Nice work!

Awesome, the demo is pretty slick! (unlike some other demos, it runs pretty fast on chrome, very impressive).

I'm impressed. Definitely an upvote.

Really good.

Wow

Amazing!
