Uhm... May this can help you to avoid converting mp3 to wav? http://openinnowhere.sourceforge.net/lameonj/
It's great I can play osu on my crapy eeepc with linux.
I'm c# guy and I think java is really fine.

the real solution is not converting mp3 -> wav... is play mp3. Try using libav/ffmpeg.

Great work (although the slider issue is quite disappointing)! Will you add the beatmap editor in the future?
How about an opsu! updater? 
Kudos on your hard work so far! I'd love to see where this goes.

Hey everyone! I apologize for the necro, but just letting you all know this project hasn't completely died yet. I pushed a lot of updates over the past few weeks, with significant memory and stability improvements, graphical polishing, many new features, and code enhancements.
Release: v0.4.0
The full changelogs are on GitHub, but these are some of the highlights since I last posted:
Release: v0.4.0
The full changelogs are on GitHub, but these are some of the highlights since I last posted:
- Memory reductions: With ~1000 beatmaps, opsu! uses about 50% less memory than in the previous version (so it's now comparable to osu!).
- Error handling: Along with better error checking, there's now a dialogue box that should appear whenever an error occurs with the exception and a prompt to report it.
- Visuals: Lots of tweaks. Most noticeably, there are hover effects on almost all menu elements now, so everything feels a lot more interactive.
- Beatmap loading: For those who had trouble with the (still relatively slow) beatmap parser, you can now press 'Esc' to interrupt the parser and run the game with the currently loaded maps. You can also press 'F5' in the song menu to reload maps (including new ones). It's also possible to restart the program from the options menu by pressing 'Ctrl+Shift+F5', without needing to reload any beatmaps.
- Development-related: opsu! is now distributed as a Maven project (thanks to Tillerino), and I rewrote parts of JarSplice to allow automatically building the standalone JARs; it only takes a single command to compile, run, or package the source code now (if you're interested, instructions are listed on the readme page). I also cleaned and rewrote a lot of the code, so it's far better organized.
New version of your app doesnt work for me. The older one(I think it was 0.3.2 or so) was functional but only in home directory.(The Songs and Skins folders must be in home directory. I dont remember if the app itselft must be in home directory.)

No, I haven't. I haven't really been focusing on the sliders since I really don't have any idea how osu! implements them. x.xLudziE12 wrote:

In the song menu, there's a little wrench icon next to the search bar. That'll take you to the options menu, and the first one is screen resolution.Asuka- wrote:

I have played opsu since the 1st version till the latest version and i just can say that this game is (almost) flawless in performance and stability apart from Bezier sliders which screws the play and the non-default skin which distracts a lot xD
However, since my workplace is mostly Linux based OS, i found that opsu! never runs above 61FPS even if the limiter is set above of 60 FPS (vsync)
On Windows, it works fine on high fps (can reach up to 240 FPS).
The Ubuntu I am using is Ubuntu 14.10 and using JDK (not JRE) 8u25 (kind of lazy to install JRE because my workplace is mostly developing software using Java and JDK usually includes the Java runtime as well)
Also, I found that if I try to use my skin, the comboburst sometimes pops up an extremely stretched slider ball which is weird (also happens occasionally with no custom skin) but i can't properly reproduce it (too random)

I actually noticed the comboburst problem too shortly after I posted the release, and quickly made a re-release after this fix. You probably have the original version of 0.4.0, so just re-download it to fix the problem. Sorry about that!chong601 wrote:
I don't really know what I can do about the FPS issue, since I'm pretty inexperienced with the low-level graphics stuff. x_x
Hey, do you think you can turn this into a better-than-osu practising client? It'd be great if we could have additional settings in the "Mods" section to change:
- Final overall AR (even if using HT, DT, EZ or HR, this overrides it)
- Final overall Circle Size (even if using EZ or HR, this overrides it)
- Speed (more selections than DT (3/2 speed) and HT (2/3 speed)
I realize that it's probably a lot of work but I think that the ability to change those on the fly for any song would make this a better place to practise than osu itself

Fixed difficulty settings (CS, AR, OD, HP) are already implemented. You can go into the options menu and change them in the "Custom" section. The mechanics are still off from osu!, though, so don't expect too much.FieryLight wrote:

Have you tried looking up other open-source Java-based MP3 player? Probably you have more luck on that (but you might need to do something with other things like speedup and timing to your preferred accuracy)euphyy wrote:

Lots of major updates in the past two weeks, so here's another release!
Release: v0.5.0
A brief overview:
Release: v0.5.0
A brief overview:
- Sliders: Thanks to fluddokt, sliders are now fixed! The old buggy sliders were replaced with two new types: circumscribed circles and linear beziers.
- Score Database: Scores are now saved to an SQLite database, so you can view past scores in the song menu much like in osu!.
- Beatmap Downloader: There's now a downloads menu that allows you to search for beatmaps, download them, and import them directly through opsu!. The downloader fetches files and data from Bloodcat, so you can only download 4 files at a time (even though there's no actual limitation code-wise).
SPOILER
I'm starting classes again in a few hours, so updates will probably be much slower again (unless anyone wants to help, as usual!). In any case, let me know what you think!(ignore the scores, they're clearly fake )
)Hey, I'd rather you didn't use the bundled osu! (audio) tracks here. Some of them aren't licenced for use outside of osu! and I'd like to respect the artist's rights where possible (considering this project is somewhat related to osu!).
Also I noticed there's some artwork that you likely don't have permission to use, so you may want to double-check on that.

Which audio tracks are you referring to? If it's the theme song, I can remove that, but I wasn't aware that osu! had a license on it (I didn't find an indication of that anywhere). The rest of the sounds are from user skins, which are all credited.
I also credited all the skin authors, and I'd be happy to remove any images if the authors want them removed.

This is working really great! I did notice the spinners were a little bit hard to finish. I think they are supposed to have some sort "weight" so they keep spinning for a little bit if you stop spinning the cursor.

Aye, development has started again? Might try and run this again on my RPi

It's not (currently?) supported by LWJGL. After doing some quick searches, it seems like people have managed to hack together something that works (see here), but I wouldn't count on the rest of the program running smoothly (or at all) on a Raspberry Pi.Doqtor Kirby wrote:

Probably will work somehow on the latest Raspberry Pi 2? Those hardware upgrades *drools* 
But yeah, making LWJGL working on Raspberry Pi gonna need to do a lot of hacking... especially when you want to have hardware acceleration
One side note, I am looking at the source code on the part of the layout of opsu!, it just doesn't feel right (some misaligned arrows, unusually giant score bars...) and see whether I can fix it using % rather than using some hacky offsetting or things that complicate things instead...

The arrows should be working (mostly) as of the latest release, but I haven't figured out the scorebars -- there's a TODO note about it probably involving cropping the transparent parts off of the images and centering from there, though I haven't had the chance to try it out yet.chong601 wrote:

It's not about a graphics card. LWJGL (the wrapper for OpenGL/OpenAL) doesn't compile for ARM processors (i.e. Raspberry Pi) without a good deal of hacking, which some people have attempted with varying success (and you can find these projects online). I wouldn't count on it working, though -- there are too many other areas where it could fail, even if you manage to get LWJGL working, and performance will probably be horrible.Doqtor Kirby wrote:
