Also, on Opera I do not see the osu! cursor (as in FF) :F Why is it?

That's right ;)
But I read that IE9 has a good support of html5, so, if you really want to use IE, you need the beta of IE9 ;)

Oh, I was talking about IE9 :l any previous versions have basically -no- HTML5 support, and ie9 is shit at best~

:/
Can anyone paste here the content of IE9's error console ? (should be called sth like "(Developper) tools"). As I don't use Windows, I can't test by my own.
Those error messages are much more useful than saying "it doesn't work" ;)

I might have been little unclear, but I was just only asking for supporting IE (as I don't think it's major, neither I use it), not that I want to play by it :3

of course, but a wide support is (I think) useful ;) And as I read that IE9 supports well html5, it would be a good idea to support it as, it means it should be quite easy to do.

A good check, would be to go there http://osu-web.tk/music.html with IE9, and tell me if it actually works (music playing AUTOMATICALLY) :) That would help a lot :)

I think I found where the main bug is from !
Edit : numbers were actually saved as string (when parsing the osu file), and this caused issues when doing math stuff (returned things like "40-30" instead of 10 :/)

Shouldn't you get something to really show rather than posting every little thing you do here? Currently it's now worse, timing and all than it was a few days ago.
This isn't even beta, its alpha, its kinda annoying.

>Yes I know I've changed my mind from what I said before :T

I'd like to know actual progress/ versions rather than in effect 'builds', which I think you should keep to your personal blog

I'll consider installing Opera so as to see what's going on. You say it's laggy, however Opera is said to be a very good browser. I'll do my best to reduce lag ;)

If you have any request/idea for osu-web, just say it :) I'll do my best ;)

Things I noticed:

When you click on a circle early, it's number and approach circle dissapear, and it is still clickable for points.
The sliders don't work, I see the track, then a yellow circle going on the track backwards, it ends up and the beginning of the slider when you are meant to click on the sliders.

But you can't "slide" on sliders ;) (you can for fun, but that won't change anything :P)

Edit : You can now "slide" on sliders !
Points do NOT increase when sliding. The only thing you can see is a message "win289", 289 (example) being the abscissa of where you cursor is ;)

Edit : now the circle on the slider turns green when sliding on it ;)

Clic anywhere around the center of the "spinner" (appears after first clic). A box tells you if you're are drawing a circle or not.

A small update
Edit : A big update :)

I finally managed to make spinners work. When there is a spinner, it's written spinner. If it's written is green it means you are actually drawing a circle. If it's red you're NOT drawing a circle.
It may be a bit laggy on old computers. The number of "points" (from your spin) is actually displayed in the window title. The bigger is it, the slower it is on old computers. removed

Please report bugs ;)

Edit : it IS possible to add the skin for spinners ;) it might be very slow :/ I'll see what I can do, when I have time ;) done

Edit : Small design changes :
  1. the spinner is now at the centre (so you have to spin around it)
  2. a line is drawn when you spin (yes you can make a nice stickman if you want :P) removed
Edit : spinning "skin" is on !

Edit : the cirlce, the "frame" and the "progress" bars are now used :)
(but the progress stuff is just based on the time and not your spinning)

Edit : know issue :
sometimes the game stops before the first spinner to start, that's b/c all the needed pictures are not loaded at the good time

They are already preloaded ;) But now, I don't check if everything is loaded before starting the game. I'll have to work on that part ;) Currently the only thing I do for preloading purpose it to let the script load for 5sec, but I doesn't seem to be enough :/

Edit : now 100% fullscreen (removed the menu bar)

There is a problem with your sliders, sometimes the're too slow. So sometimes you miss hit markers when following a slider.

It's a little buggy but that's to be expected (it's a rhythm game clone running in javascript) and that site is there to show us his progress (According to previous posts, it's not completely up to date with development version). Cut him some slack :)

Actually, it's almost always the latest dev version on the website, except when I'm doing some complex stuff (ie spinner slider loader...) that I handle in one lonely .html file (cause it can be really buggy) ;)

Don't worry I'm working on that ;) The main problem is that all the pictures (needed for the spinner) are not all loaded when the game starts. And if the picture ("skin") isn't loaded, javascript actually crashes ;) That's why I'm working on a loader.
Lag is also due the vast amount of work that is required (images + big array check + drawing the whole thing + mouse move detection + ...) each 50ms (20times/sec)

Aah okay, yeah loading would be a big step forward.

As for the lag, my PC is towards the high end, a decent graphics card, processor etc, and chrome uses hardware acceleration. So to put it simple, it's not going to be smooth on 90% of PCs unless optimized, just as a heads-up

Lag is a real issue :/

The loader will allow me to extend the UI. So I'm starting to think about other stuff such as a beatmap picker and such things. The UI will be based on osu's. Here is a quick mockup

Feel free to make suggestions :)

PS : I just saw that the mockup is in french, translations
SPOILER
  1. boxes on the right stand for beatmaps
  2. bottom-right is a "share" link
  3. the button next to the link is for donations (needed for a paid server)
  4. the picker next to the button is for settings (special modes)
  5. the slider on the bottom-left is for volume
  6. 3 boxes on the left are informations about selected beatmap

Edit : THE WEBSITE MAY NOT WORK AT ALL RIGHT NOW as I'm trying to implement the loader ;)
Edit : loader is getting good :)
Edit : wow, it takes over 20sec to load all the pictures (151 pictures to be accurate)

Well, indeed it's not 100% finished ;) I was very close to the end but I had to stop ;) I'll finish that asap ;)

Edit :
  1. for those wondering, it's normal that the loader goes "back" at the beggining of the load (ie 66% to 3%). Indeed some pages that are loaded start to load other pages (for examples, images)
  2. Now, there is a real (graphic) loader ! :)
    woks fine on Firefox 4 (latest biuld from launchpad)
  3. I'm improving the HitObjects colors. The color should now follow what's said in the .osu. Next step is to put on a gradient for design purpose :P postponed
  4. Btw, I know the music and the beatmap do not match. I also konw that there are issues when sliders are vertical ;) fixed
  5. should now start to appear in search engines (Google & co) -- done (description : "osu! for browsers.")
  6. loads but doesn't start as I'm trying to set up sth (.osu parsing client - javascript - side) fixed
  7. host is down
  8. parsing client-side is WIP done
  9. favicon added
    server side (php) less used (→ ajax) and even useless ;)
  10. HitSounds (normal + whistle) are here (both ogg and mp3)

substantial improvements have been made, but i think you need to work on fixing core gameplay issues (such as sliders and calculating their length and path properly) before making anything else really

hitsounds also need to be added as they are a pretty core part of osu

Sliders are still an issue. I'm also working on HitSounds but I'm having weird issues. For now I disabled them, until a good fix is found.

The main issue I have with sliders is actually to know the way they work. For example I have *no idea* about the way their speed is calculated. As I have no idea at all, I made all of them 1.5sec long as a value is needed to display them.

It would be so cool if you could give me any detailed information about sliders speed ! (math formulas or sth like that) :)

"beat": the length of a beat can be calculated from the bpm (eg. 60 beats per minute = 1000 milliseconds per beat)
One question : how do I know the bpm of the beatmap ?
I think (not sure at all) that the default value is 60bpm, and can be changed with TimingPoints (x2, x3), right ?
It's not specified in the the osu file [General] nor in the [Metadata] nor in the [Difficulty], right ?

We are still having issues with browsers compatibility. We are also working on that.

I just (when writing this answer) fixed compatibility with Firefox 3.6 and Opera ;)
So it seems to work on Firefox 3.6, 4, Chromium, Opera (on Linux platform at least). However it may not work for everybody :/
It's not expected to work on IE8.

We recommand Firefox 4 (beta) for now ;) Others may also work.

If you still have issues try to force-refresh the whole website ;)
Therefor, close osu-web tab, wipe browser cache, go back to osu-web, try shif+F5

Edit : doesn't work on Opera for now

just pick a browser which works and block all other user agents from playing it until you've fixed everything up

your development approach seems really scattered - concentrate on the stuff that is actually important (ie core gameplay) and worry about compatibility with anything bar your chosen browser later

Even downloading the portable version can be long, especially when we are at school (blocked downloading website, and need to use proxies etc...). But that's sure the browsers are not the main problem, I didn't meant that.

not always that easy. Especially when at school. And it's faster to use Firefox 3.6 since it's installed where we "work" on osu-web there.
And browser support isn't that hard (except when having weird issues with some browsers). So as to fix Firefox 3.6 support yesterday it only took me 5min. The main issue with browser compatibility is that I never check the compatibility status. I mainly manage to have it to work on my browser and then fix small compatibilty issues when at school, so as to be able to make some quick tests.

And don't worry, we're working on sliders :)

You should probably make the game playable without sliders before you attempt them. Timing still seems quite off, along with animations and handling of multiple hitObjects in stacks or on-screen at the same time. Frame-rate could also possibly be improved before attempting more advanced stuff.

Speaking about frame-rate, the time taken to "make" the whole drawing stuff is now displayed in the bottom-left corner. I also removed the offset during 2 refreshes. For me it's around 9ms when the screen is empty and goes to 30-40ms when playing Strange Program, on Firefox 4.

The offset (between music and hitObjects) comes from the browser audio API. I can't do anything for that. I always take the most recent time value.

i sure hope the browser audio API at least produces a stable offset - you can just force the game to set a new universal offset to compensate for it. if the offset fluctuates under browser load, then you may have a serious, nigh crippling issue that would pretty much ruin your project.

perhaps you should switch focus from other stuff and try to get a timing editor working within the browser so you can see what kind of restrictions you're going to have to work with before you proceed any further

really strange idea ! that would even be worse ;)

I made a small test beatmap (called "test" on osu web). it only plays in Firefox. there is 1 single sound with a hitCircle. that way the offset is more easy to see (no chrome version of that beatmap since I'm having some issues with Audacity conversion right now)

Edit : huge improvement made on sliders. please note that only the first timingpoint is used

Edit : HitSounds added. Ball on sliders added. Reverse sliders added.
Coming soon : gameplay ratio and maybe storyboard. That will rock :)

Edit : just made a small facebook fan page https://www.facebook.com/pages/Osu-web/108368515907391 (I know I should better work on osu-web itself - but I'm a human too ;) )

Your scaling is off; you aren't enforcing aspect ratio at all <snip>

Getting slider curves working properly and tring to resolve the offset issue should probably come before storyboards lol

Slider curves are quite hard to do ;) it requires bezier or catmull, which means math stuff. It's on my todolist, but before making any working code for curves, I'll have to understand what wikipedia says about bezier and catmull curves.
Indeed the main issue is that html5's <canvas> only supports bezier curves with 2 handlers and beatmaps often user more than 2 points for their sliders... There is nothing related to catmull curves in <canvas> I'lll have to make everything by hand. And it might slow the game down :/

Storyboard seems to be easier to do ;) less math issues :)

I can't do anything for offsets. The best thing I can do is to tell you to use Firefox 4 (and not 3.6) or Chrome ;)
(for me the offset is near 1 second on firefox 3.6 but there is almost no offset on firefox 4)

You can precalculate all the bezier curve and hold them in a table. More memory usage, faster / no lag during gameplay.

Most of the things so far have been

A developer should never say 'I can't do anything about' until you've spent at least a significant amount of time trying/researching.

Backgrounds are now displayed.
A "start page" is now present (for new users).

Beatmaps are now cached in your browser (html5 stuff). This means that once they are in your cache, the game is *much* faster to load :)
("only" 100 50 files are loaded instead of over 300)

Edit : We added a dev-version of osu!web. http://osu-web.tk/unstable/
That way, we can keep osu-web.tk more stable :)

Edit : seems to be working atm on iOS 4.2.1, quite laggy, images not scaled down. etc. Looks better if you add it to your HomeScreen ;)

Edit : FPS is now displayed :)
For me ~50 on Fx4 and <20 on iPhone (and <10 in landscape)
Sometimes the "lag" is caused by js' <audio> API (was the case with Fx4 a few days ago - we found a workaround)

Well, not for now. I got a lot of stuff to do for school, and for my studies next year.
I'm too buzy to work on osu-web, even if I want to. But I'll work on it when I have enough free time ;)

If you want to code with me, you can go there → https://launchpad.net/osu-web/ and submit code. It will be put (manually) on http://osu-web.tk/unstable/ until I can give it a closer look, so as to send it to http://osu-web.tk/ (stable version)

This game was really unstable for me on Chrome. I suggest you scale it WAYYY back so the game is playable, and make every update playable until you can play the whole thing stable.

Bezier curves are now working !
You can test it @ http://osu-web.tk/unstable/

NB. bezier curves are on the unstable branch, thus other features may not work (eg spinners)

Doesn't load in dev chrome, but works really nicely in FF4 actually, I'm impressed.

One thing, once you resume, the play window won't disappear

Doesn't work in Firefox 3.6.x. Song never loads. I suggest testing on more than one browser, and avoiding the same regressions as you move forward.

Wow, I never expected this to be completed to this extent, good job. Although it was running under 30fps the whole time according to the counter at the bottom right and I had to ignore the approach circles completely for timing.
