Release: v0.7.0
A lot of general enhancements and fixes with this release -- please refer to the release notes for details. A few quick points:
  1. Beatmap cache: Beatmaps are now cached in a database after the application starts. Coupled with some other tweaks, loading times are now drastically lower (ex. loading is about 6x faster on my computer).
  2. Automatic updater: All future releases can be automatically downloaded from within the application.
  3. Bug fixes: Major spinner improvements (fade in effect, support counterclockwise rotation, show RPM for "auto"/"spun-out" mods, remove dependence on FPS); slider calculation fixes; multiple sound effects can now play simultaneously; and many others.

Thanks again for all the support!

Fixed ^

Now it works ;) , and the loading time for songs was much faster.

Thank you SO MUCH for a pause button option in the android version this update! Keep it up!

I started playing Osu for the past month so I'm fairly new to the Osu community. So why is there a need to make an Osu clone except have it open source? Isn't the main game polished enough that there wouldn't be a need to recreate it?

As of now, peppy still haven't make osu! source code open for public viewing. IIRC, he did say that it will be released by end of this year.
opsu! is actually a reimplementation of the original osu! game (no osu!devs are involved in this project afaik) and it is mainly contributed by euphyy (itdelatrisu) and hanawanta (fluddokt) and some players submitting bug reports.

Another reason of making clones is because osu! isn't really available other than Windows (although it is supported in Mac and Linux via Wine but heh, not everyone have good experience with those like I can't even make it work without recompiling my kernel :o)

Another reason is because they are just have nothing to do and decided on trying to make their own :)

Examples of the osu! clone available are:
  1. osu!iPhone (currently dead since the dev (nuddles) stopped developing it)
  2. osu!droid (presumably dead since the devs (Pesets and neico) not actuvely maintaining the code and tbh, the game suffers from multiple issues ranging from lack of support for newer versions of .osu format, memory corruption and image corruption)
  3. osu!WP (not sure about the status but probably still active)
  4. osuweb (browser version, not tested yet)
  5. osu!uebu (not released yet, browser version, HTML5 based with WebGL probably still in active development, the dev (Frowned) is working on it, but no ETA on the release date)
  6. Wojtkosu (XNA based, not active i think? the thread is 2 years old since the dev last posted in the forums :? )

euphyy, how do you use a custom skin? I really don't like the preset skin and there is a Skins folder. I'm sure there is a purpose for it. (Is there?)

I put Black 2014 in the folder, but there's no skin option or anything.

EDIT: I fixed it, nvm.

Release: v0.8.0
This version includes mostly gameplay-related updates, summarized below:
  1. Replays: There is now support for recording, parsing, and exporting game replays. fluddokt helped fix many of the major problems, but please report any bugs you find. Note that this can play osu! replays (you'll have to do it manually, since there's no UI for it), but osu! cannot play opsu! replays (even though the output format is nearly identical).
  2. Game mods: This update adds the "flashlight" and "autopilot" mods, and fixes "auto" (cursor is now shown) and "hard rock" (hit object coordinates are now flipped).
  3. Other: Implemented follow points; added track previews in the downloads menu; support loading @2x images; and a handful of other bug fixes and tweaks.

As always, thanks for all your feedback!

Note 1: This update includes changes to the score database format, but if all goes well, the database should be altered automatically when opening the new version. Make a backup of your old database if you want.

Note 2 (to peppy): I'm currently using the osu! servers for the track previews -- as I've seen some other sites do -- but let me know if you want me to remove this.

Sorry, there's still no support for skin switching or skin.ini. x.x

It's really just for fun, but as chong601 mentioned, opsu! runs on more platforms than osu! and will also work on lower-end computers. There are plenty of other things you can do, too, but you'll have to be creative. (Here's an example.)

Wonderful update! I am very happy with the way this is going :)

Two thing I would like to point out:

1. Flashlight does not get any smaller as the combo increases (I think) . I don't know if you intend it that way.
2. The music offset is different for different songs. (I use -100ms or -150ms ) one of those two worked for the songs I played, but I had to change them depeding on the song. Any fix for the offset to just make it automatic would be wonderful. :p

Suggestion:

- In-game custom frame cap (I know its on the .cfg file) :p
- opsu! logo , instead of the default java logo shortcut.
- How to change skin? Make it more obvious :p


Issues:

After update, and restart the game: https://github.com/itdelatrisu/opsu/issues/55
Then this happened https://github.com/itdelatrisu/opsu/issues/56
Then the update got reverted? And it asks me to update many time, feels like its in a loop.
and this https://github.com/itdelatrisu/opsu/issues/57

cheers :D

  1. Flashlight does get smaller at 100 and 200 combo, as stated on the wiki. I didn't verify if that's correct, but that's what's currently implemented.
  2. The music offset option is really just a bad fix for whatever mysterious problem is causing the inconsistent beatmap offsets. I could never figure out what was wrong...
  3. What do you mean by "custom frame cap"? Like, let the user select any FPS? (That sounds reasonable, as long as I cap it. XD But it wouldn't be as convenient if you wanted to quickly switch between the current preset values.)
  4. Custom app icons aren't possible as long as I'm distributing JARs (and not native executables). I don't plan on changing this at the moment, sorry.
  5. Skin-related updates have been on my to-do list for a long time, but I honestly can't say if/when I'll get to it. I can't bring myself to take the time to figure out what everything in skin.ini does... :P


As for your issues: the updater downloads the new JAR and saves it as a new file -- it doesn't overwrite the old one. I think all of your problems are being caused by you running 0.7.0 instead of 0.8.0 after your database gets updated -- let me know if that resolves everything.

custom frame cap: http://puu.sh/gHOds/de9132fd33.png (but in game, so I could type the fps limit)
So, switch between 60fps, 120fps, 240fps, customfps.


And yes, that was the issue!
It's a little un-intuitive that it doesn't overwrite the older version. But anyways, that was it. :)

I like to idle in open-source project chatrooms :D

So is there any official chatroom (preferably IRC) for opsu? If not, I'll be idling in #opsu on freenode by myself in the meantime

Could you make android version of the game more suitable for mobile? Hit objects are too small on smaller devices, sliding is too sensitive, there are no options, and config files are saved in external storage rather than internal.

I just found this awesome apk for Android so I'm still testing it out but till now it's awesome, haven't seen any bugs really.

Suggestions:
- Sign In option for the game so that your process could be like saved? (I don't know if it's possible already haven't seen it) Because I find that my phone works like a mouse tab on the insane beatmaps.
- Android gameplay bigger, I have a large screen (6.5inch) and it tends to get annoying with the small icons.

I'll report if I find bugs anywhere! :D

This is amazing i hope you keep going. Android compatibility is awesome

Awesome Android port! Although is it just me or is the accuracy grading a bit too agressive, having a hard time to get good accuracy from that I've got good accuracy. Also, the new cursor seems to be a bit delayed(probably the reason why accuracy is low). And last note, why aren't you able to use the original osu! skin? Osu!Droid was able to use the old skin. ;)

Delayed cursor may be the touchscreen issue, not game issue (since most android phones have input delay on touchscreen)
The reason opsu! can't use osu! skin is because due to peppy copyright on skin elements (only allowed in osu!, requires explicit permission if wanted to use outside or osu!)
Quote from the original thread (under LICENCE box):
All osu! graphic and other game assets are copyright ppy Pty Ltd.

You are granted permission to use the elements contained within this archive as a template for creating your own skins. You can modify these in any way you see fit. Please do not include the resources if you haven't modified them; the defaults will automatically be used in this case.

You are NOT permitted to use these graphics outside of skins and/or beatmaps. This includes using them on other websites, games, products etc.

If you would like to use the resources outside of the scope provided above, please contact me at pe@ppy.sh

One extra thing to add:
opsu-android requires 200 MB of RAM to run (may require up to 300 MB on certain occasions), so phones with less than 1 GB of RAM on device may not work properly (or wouldn't start at all)

I found something that feels like a bug with the sliders, but I've only seen it happen on a single map so far (didn't test very many maps). It's like the slider gets "caught" on the end with like an extra beat and so you have to hold it at the end of the slider while the ball seems to spin in place for that beat.

Map in question (Normal):
https://osu.ppy.sh/s/2585

It's fairly close to the beginning (the slider is shaped like an upside down question mark) and should be noticeable by having one of the slider beat stars on the actual end.

You mean this slider?
The said slider in osu!:


The same slider in opsu!:


The code of the slider in the .osu file:
248,251,57161,2,2,L|312:251|312:200|248:200|249:91,1,280,2|0
Yeah confirming that some sliders are really funky on opsu! due to incomplete implementation of the sliders (current available sliders are Bezier and CircumscribedCircle, other types of sliders such as catmull and linear sliders aren't available yet)
The slider is actually a Linear slider, which is iirc isn't available and is then fall back to Bezier which destroys it xD

EDIT: You can report this on Github since he mostly active there (or I can help you forward this bug to the issues tracker)

Oh my science! I can't believe that I didn't discover this project until now. I always want to find a open source osu implementation to learn from and I finally find it today! Thank you euphyy for creating such a amazing project! I will definitely try to help if I get some free time! :)
chong601
you know, euphyy's code is so advanced that my lecturer, company supervisor and friends have obtained the latest copy of the source code to investigate the code structure

even if i know programming, his programming skills exceeded my range of understanding xD
