Hey guys i've started work on an osu! port to HTML5, some of the features that will be in it upon release will be:
  1. All osu! standard beatmaps from desktop version will be playable
  2. Beatmap videos will play
  3. All skins for osu! will work with osu! uebu
  4. All beatmap-specific skins will work with osu! uebu
  5. asm.js core for speed (should run about only 1/16th slower or less than osu! desktop)
  6. WebGL, your html5 osu! will be GPU accelerated just like osu! desktop.
  7. Local storage of records/replays
  8. Multithreaded with WebWorkers so you can get even better performance.
  9. Other stuff i've yet to decide on.
List of things I will never do:
  1. Support any microsoft browser.
  2. Support IOS Safari.
  3. Add Catch The Beat.
Stuff that I would like to include but probably won't for a long time for various reasons:
  1. Bancho connection (would need peppy's permission)
  2. Tycho mode
  3. osu! mania
  4. Javascript Video Codecs
  5. Beatmap editor
Finally I follow this up with a teaser screenshot of the loading screen:

5. Beatmap editor
Why would you need next editor when there is osu! one?

Also do you have any working release, or is it just "what-I'll-maybe-do"?

This is not "what-I'll-maybe-do" it's "what i'm doing right now but isn't finished yet", so no it's not working yet but i'll have a few of the bullet points finished soon.

Edit: the reason why i won't add a beatmap editor for quite a while is because it's already in osu!

Oh sorry, my bad, I overlook the header of this, and missed "but probably won't" part.

Anyway good luck with that, I wish you best to see it in working state ;)

It won't lag, im using WebGL which allows me to use your graphics card, and asm.js which is almost identical in speed to compiled code. Asm.js and WebGL are fast enough to run Unreal Tournament 3 in a web browser, so you shouldn't get any lag, if you can run what i linked to below at all (even with lag) you should have no problems with my port.

Unreal 3 Engine in a web browser (if you aren't running firefox hit "try anyway"):

What does uebu derive from (if it does from anything)?

The name "uebu" is just the romanji for the japanese word for the world wide web, when pronounced it sounds like oo-web-oo. Just like how osu is the romanji for "push" (as in pushing a button) in japanese.

Edit: apparently this isn't where the name osu comes from but it is true that osu means push in japanese.

I thought it was some kind of greeting, originating from ... I don't remember this word :/

try firefox, or setting your browser to use software OpenGL renderer.

I'll keep an eye on your project, it looks promising :)

Yep, it comes from ohayo gozaimasu!

I've gotten what i've already written of the asm.js rendering code to compile in Odinmonkey (Firefox's asm.js Engine)... that only took 4 hours (asm.js is really hard to write correctly).

I would be very interested in having an editor for firefox. It would be cool to edit maps way to college on a tablet... or something.
As a Linux user, an editor is a good idea, as there is no native client here.

Your project is very interesting, and I think it has a better approach than the others that are out there.

Good Luck!! :D

Struggling with the javascript libraries for unzipping beatmaps and Skins, It would be nice if there was a simple up to date library for it, i'm having to write my own zip parser and use the zpipe DEFLATE implementation.

Edit: I found a library but it's a little big, I may actually compress the compressing code and use the decompressing code to decompress the compressing code :P

first are you running XP?
if so that's why.

if that's not the case then try adding this to the end of the chrome shortcut:
--ignore-gpu-blacklist

Edit: just got skin/replay/beatmap decompression working, now i need to do Filesystem IO and skin/replay/beatmap parsing and the majority of the display code as well as game logic.

I've gotten beatmap decompression done, and skin loading is mostly finished...

Do you have any plans to port this to a windows store app?

After 8.1 all the technologies you're using can work on the in store apps.

A good motive to do it in HTML5. For Linux users this is already a plus just to the acceleratedi gpu did not lagg. I also wanted to do a project in HTML5, but as for now, the lack of time and motivation :(

sry for my english ;3

File-system storage is almost complete, i just need to debug an issue with the storage API that wraps the JavaScript Filesystem API reporting it's being given more space than it actually is, and add the ability to open files for reading instead of write-only. After this the five remaining things are beatmap parsing, score calculation, input/replays and rendering/webgl shaders.

For those of you who are interested, osu! uebu now consists of:
11 javascript files, 1 html file (the page it runs on), 1 css file (styling for that page) and 1 osk file(containing the default osu! skin*), each javascript file has a length of between 140 to 350 lines of code.


*i have permission from peppy to use osu! graphical assets, and the name osu! in osu! uebu.

see item 1 on the list

As a side note: asm.js won't be much faster than normal js if you aren't using a browser that has an asm.js compiler built in (i.e. Firefox 24 or later (no other browsers currently have an asm.js compiler)).

Edit: sorry for the double post.

Sounds like quite a big leap for osu!
Any news on progression?

Would it be possible to have access to what you've done so far? I'm quite intrested about how you're doing it as I have yet to learn how to do graphic stuff with javascript/html5.

Actually I'm still wondering how you managed to extract osz files using JavaScript? I know it's possible with PHP but JS?

And I'm still figuring out how slider-drawing in canvas works TT

I think this will be your answer: zip.js
You can also check this thread on stackoverflow.

I didn't use zip.js but i used a similar library yes. I'm currently working on a method for storing the uncompressed files if local file system access isn't available.

Interest and will to help I do have, and I'm also able to use javascript, but haven't seen other way to display things other then HTML/css (snake using table is so wonderful XD) with it and I'm also starting to learn object oriented programation in flash...
may not be much that I can do, but I'm willing to look at new things if needed

It's being done entirely in ECMAScript (standardized JavaScript) on the clientside so I doubt we'll need php but thanks anyway.

Hi, I was thinking about starting a similar project and got directed here....
Are there any plans to make this project open source so I could help in some way?

I'm aware of a similar project around here called osu!web but they seem dead with a working demo released.
Their latest commit on git was Feb 26, 2013 (almost 2 years ago at the time of writing this) with 0 contributors on the repo.
How's the progress over here?

Nice naming btw, had me scratching my head until I read it out loud :)

I've been a bit busy lately, i'm planning on working more on this sometime soon. My computer is currently having issues where it hangs randomly so that's kind of getting in my way.

If it's ok with you, maybe you can share the code with me so I could get a better idea of this project in its current state?
