2016-09 dev meeting

published 03 Oct 2016

Our second public meeting was a pretty resounding success. Read on to find out what we spoke about!


Despite the majority of the core developers being absent for this meeting, we still got a lot done. The core team spent a lot of time together in closed-group coding sessions during the last month, meaning some pretty huge progress was made overall.

  • Work on the osu!framework (and LAZER implementation) is nearing its end stages. A lot of the ground-level stuff required to build the game within the new framework is now done, with peppy showcasing a number of the core features of the new engine during the dev stream. We’re really getting close to the culmination of all the work that has gone into the LAZER refactor over the past few months, and while the end is still a few months away, it isn’t anywhere near as distant as it once was.

    On the topic of the osu!framework, peppy is proud to report that the rework will also boast significantly improved performance compared to the old engine due to a complete overhaul on how input handling and drawing are processed at the game level. The particulars of this were featured briefly on his stream of the meeting.

  • smoogipooo has been hard at work on the titular scorev2 reworks for osu!mania, osu!catch and osu!standard. Community feedback on the proposed score changes is vital to this process, so head on over to those threads and give your input on the slated changes.
  • A full rework of the community wiki is underway, porting existing articles from the dilapidated MediaWiki format into Markdown on Github. The wiki has been closed to contributions for a while, but was fairly complete in its content before that point. Intrepid contributors can head over to the repo, fork it, and port any missing articles across into Markdown, then submit a pull request to have their work added to the wiki. The new wiki design will be congruent with the osu!next site design, and an entirely new system in its own right.
  • A big push to move the forums over to the new version is being made, and expected to be completed soon. The chief web developer for the new site was on a break during the past month or so, but is expected to return shortly. LiquidPL has been hard at work on various redesigns as well. Say your farewells to the old software, because it won’t be around for much longer.
  • The osu!tournament backend that supports community tournaments continues to improve. We still plan to allow full access to the osu!tournament client (but not the !mp player command suite) for all supporters in the near future, pending some internal changes to allow that to happen.
  • We’re trialing a fairly complicated form of community collaborative beatmapping using the new submission system. Head on over to the news post for more details. This new format of all-mode, all-difficulty contests judged by popular vote is expected to be a replacement for the select-judged beatmapping contest, though the old format will not disappear completely.
  • More details about the upcoming Spotlight system were revealed. Spotlights will replace the old “map pack” model that was famous in the earlier days of osu!, and will reward individual medals for completing a pack fully.
  • More Hush-Hush medals incoming. They’re harder than the last set, too. Not necessarily in actual game-skill difficulty, but some of them are very heavily riddle oriented.
  • We plan to hold more media-related contests (fanart, videos, storyboards, etc) in the near future. The overwhelming engagement by the community for the Taiko mascot contest was a pretty strong indicator that people definitely enjoy these sorts of contests, and that we have some amazingly talented individuals in the community who will compete in them. We’ll be bringing back the main-menu background rotation contests that were popular a few years ago.

    Oh, and fear not - the Taikonator will be making an appearance somewhere.

  • We’ll be looking at the other non-standard gamemode mascots for potential redesigns in the coming months. flyte has a very specific vision for the standard to which our mascots will be held, and some of them do not really fit that vision as they are now. Keep your eyes peeled!

That’s about all for now, but if you’d like to hear the dev meeting in its entirety, peppy recorded the whole stream over on his youtube channel. Hearing flyte discuss mascots by how they appear naked is probably the highlight of the stream, so make sure to give it a listen if you’re interested.

See you next time!


2016-08 dev meeting

published 28 Aug 2016

Hi, Ephemeral reporting in with updates from the latest meeting. This time around it may have been closed to the public, but that doesn’t mean that things didn’t happen!

Before we get stuck into stuff, we’ve decided to hold every second dev meeting in the public format we trialed last month. Hosting public meetings means we don’t always get to discuss everything that we need to, so we’re cutting back on them for the meanwhile as a bunch of projects start to reach their final stages all at once. Never fear though - we’ll be back with one next month!

We’ll also be taking a few vetted questions at the end of the next public meeting, so if you’ve got something you want to ask, you might want to consider fleshing it out before then!

Now, onto the things:

  • The backend behind the medal system received a significant overhaul. We ran into some issues with implementing the recent batch of Hush-Hush medals stemming from a bunch of organizational and production shortfalls. MillhioreF spent a bunch of time rewriting the existing system to fix a lot of long-standing issues with achievement detection, and also made it significantly easier for us to draft new medals in the future. Which we will be doing a lot of, by the by.
  • Changes are coming to the ranking system which will see a greater variety of maps equipped with scoreboards. Vague, but exciting. There’s not a lot more that we can say about this right now, but we’ve got something fairly big planned, and we think it will fix a lot of long-standing issues with and complaints about the ranking system as it currently stands.
  • The titular open-source osu! project has been released to the public. This is important as it is the first truly visible fruit from the long labours surrounding the LAZER project. peppy showcased a quick game(mode?) recently using the framework, and thanks to the hard work of several key contributors from the osu!dev community, the framework also builds cleanly under Linux and OS X as well. This is a pretty big deal, so expect to see a full-length peppypost on this blog about it sometime soon.
  • The Ranking Charts will be significantly overhauled in the near future. The Charts system has sort of been a red-headed stepchild since its inception - never really receiving the love nor the attention that it desperately deserved. Going forward, we’re looking to merge the old “map pack” bundles into “Spotlights” which will then form the bulk of what currently represents the monthly Ranking Charts. New Spotlights will be released on a monthly basis by much the same people that currently do the Ranking Charts, and we’re also looking into a new format of prizes for people who compete in them.
  • The new osu!tablet model has arrived and is available for purchase in the store. Check it out for yourself!. Boasting a stronger, rechargeable pen and some firmware differences from the base HUION model that improves the usability for “hover” style players, the 2016 osu!tablet is as mean as it is sleek.
  • The osu!tournament client will soon be available to everyone, all the time. This is coupled with a number of changes to our tournament support back-end which will make it significantly easier for us to manage player-run tournaments going forward. The wiki has the details on how to enable the tournament mode if you’re curious.

It was a very productive meeting this month. Things are starting to pick up a little bit overall, even if we have had a few slow months so far.

See you next month!

(or maybe sooner?)


a little framework test

published 12 Aug 2016

We’ve been doing a lot of work behind the scenes on the framework osu! runs on (the lazer project). Today I took a step back to test a week of intense coding changes with smoogipooo to see how things feel and work.

I made a little game which took 5 hours and 375 lines of code to write. Would have been 2 or 3 hours if I didn’t find some bugs along the way with the framework (this was my intention, so I am very happy).

Download here (30mb because it contains osu! resources, sorry)


  • W to move up
  • S to move down
  • D to boost
  • tab to autoplay

I’ll release the full source for this in the near future. And yes, this will likely appear as a game mode for osu! in the future (maybe a just-for-fun one like target practice :).

We are making great progress here. Big cogs are turning!

Enjoy your weekend!


come join us devs!

published 01 Aug 2016

I’ve mentioned this in previous posts, but wanted a single post I can link to when inviting new people to the discord network, so here it is!

Recently we moved our public dev chat from slack to discord, and it has been working quite well so far. Anyone is welcome to join, but in order to talk there you will need to follow the instructions in the #announcement channel to get approved. This is just to keep things safe and secure for all participands.

If you’re interested in following what is happening in the world of osu! dev - whether you want to participate or just watch over what we are doing - please follow this link to join the network.

DO NOTE that this is intended for development talk only. We don’t tolerate chit-chat. There are plenty of other discord networks for such chat to happen, but this one is low traffic so those involved in dev are able to keep up with everything going on without getting overwhelmed.


2016-07 dev meeting

published 30 Jul 2016

Turns out we’ve had a lot to talk about this July, what-with two dev meeting posts in a single month. Best of all, this new one was public!

To much excitement from the community at large, we held July’s meeting publicly in our dedicated development Discord server, with peppy himself streaming the affair via his twitch channel. While only the people participating in the meeting could actually speak, anyone with access to the server could commentate on the goings-on in a special channel. This was something entirely new for us - and we’re definitely looking at making this a more regular thing.

Here’s what got done this month:

  • The new sleek, black osu!tablet has been ordered and will be in the store within a month. Not the month, but a month. flyte proudly announced in the meetings that the new design features less in-your-face triangles and more of his signature design finesse. Whatever that means.
  • Work on LAZER continues at a slow pace. We’ve all but given up attempting to put a timeframe on its release date, since the developers are taking things slowly and adhering to strict standards in their work on the refactor. Lots of work is still being done each month (you can see for yourself if you’re a member of the osu!dev discord - #osu-lazer channel has the details), but things are still very far away from even a proper CE release as of yet.
  • We released a new set of achievements (and medals) in the Mod Spotlight series. These medals are all about experimenting with mods that some players may never have even looked at before, and are the gentle introduction to the sort of stuff required for the upcoming Hush-Hush 2 medals which will seriously test people’s mettle and riddle-solving skills.
  • The new forums are excruciatingly close to being fully released. If you’re fond of the current forums, start saying your farewells, because with nanaya’s work on the implementation almost entirely complete, they’ll not be around for much longer. This will be the most visible part of osu!next that people will see before the actual client, and we’re really excited to see it almost come to fruition.
  • A new contest system has been developed that paves the way for community votes and weekly contests of all kinds. nekodex has been hard at work on a brand new contest system that supports not only jury judging, but also community voting as well. With this coming live within the next week for the circles! remix contest, expect more contests coming for all sorts of things within the year.
  • Competitive score adjustments for Mania mode (scorev2) will be complete before the MWC commences. smoog might be sweating, but he’s pulling out all the stops to get this done. scorev2 for Mania means a better show for both the players and the audience in the upcoming Mania World Cup.
  • We’ve vastly expanded our collection of featured/licensed artists. There’s over 300 songs in the catalogue now, and nearly 100 of those are timed and ready to go. Yes, community favourite Helblinde is among them. All of us love his stuff.
  • The difficulty algorithm received a sneaky adjustment to make sliders worth less for star rating calculations. The most obvious example of this (for anyone who followed the Aspire contest in any case) was Monstrata’s winning map going from 8+ stars down to 5~. Don’t expect to see much (if any) change on other maps though, as it shouldn’t significantly affect the rating of pretty much any other map.

If you’ve got a spare hour and want to watch the stream yourself, head over here.

We ended the meeting by playing one of the remixes from the recent circles! remix contest, performed by the masterful BilliumMoto. Note that this track - along with some amazing other entries - will be available for voting in the coming days!

See you next month!
