wieku / danser-go

Dancing visualizer of osu! standard maps and custom osu! client written in Go. Also a generator for osu! videos.

danser-go

danser-go is a CLI visualisation tool for osu!standard maps.

As danser is in development phase, some things may break. If that happens please fill an issue with as much detail as possible.

WARNING: Because of MacOS' poor OpenGL support, danser-go won't run on that platform. Please use dual-booted Windows/Linux instead.

Examples

• Omoi - Chiisana Koi no Uta (Synth Rock Cover) [Kroytz's EX EX] - TAG2 Mirror Collage
• Sex Whales & Fraxo - Dead To Me (feat. Lox Chatterbox) [extrad1881 (ar 10)] Mirror Collage
• Nightcore - Flower Dance [Amachoco ARX.7] Mandala Mirror Collage
• Flower Dance (osu! cursordance)
• osu! top 50 replays knockout | xi - FREEDOM DiVE [ENDLESS DiMENSiONS]
• osu! top 50 knockout | YURRY CANNON - Suicide Parade [Sakase]
• osu! top 50 replays knockout | Kobaryo - Bookmaker [Corrupt The World]

Running Danser

You can download the newest Windows/Linux 64-bit binaries from releases.

After unpacking it to your desired directory, you need to run it using launcher (using danser-launcher executable) or a command-line application/terminal:

Windows cmd:

danser <arguments>

Linux / Unix / git bash / Powershell:

./danser <arguments>

If you try to run danser (not danser-launcher) without any arguments there's a surprise waiting for you ;)

Run arguments

• -artist="NOMA" or -a="NOMA"
• -title="Brain Power" or -t="Brain Power"
• -difficulty="Overdrive" or -d="Overdrive"
• -creator="Skystar" or -c="Skystar"
• -md5=hash - overrides all map selection arguments and attempts to find .osu file matching the specified MD5 hash
• -id=433005 - overrides all map selection arguments and attempts to find .osu file with matching BeatmapID (not BeatmapSetID!)
• -cursors=2 - number of cursors used in mirror collage
• -tag=2 - number of cursors in TAG mode
• -speed=1.5 - music speed. Value of 1.5 is equal to osu!'s DoubleTime mod.
• -pitch=1.5 - music pitch. Value of 1.5 is equal to osu!'s Nightcore pitch. To recreate osu!'s Nightcore mod, use with speed 1.5
• -settings=name - settings filename - for example settings/name.json instead of settings/default.json
• -debug - shows additional info when running Danser, overrides Graphics.DrawFPS setting
• -play - play through the map in osu!standard mode
• -skip - skips map's intro like in osu!
• -start=20.5 - start the map at a given time (in seconds)
• -end=30.5 - end the map at the given time (in seconds)
• -knockout - knockout mode
• -knockout2="[\"replay1.osr\",\"replay2.osr\"]" - knockout mode, but instead of using danser's replays folder, sources replays from the given JSON array. Knockout.MaxPlayers and Knockout.ExcludeMods settings are ignored.
• -record - Records danser's output to a video file. Needs an accessible FFmpeg installation.
• -out=abcd - overrides -record flag, records to a given filename instead of auto-generating it. Extension of the file is set in settings. When the -ss flag is used, this sets the output filename as well.
• -replay="path_to_replay.osr" or -r="path_to_replay.osr" - plays a given replay file. Be sure to replace \ with \\ or /. Overrides all map selection arguments
• -mods=HDHR - displays the map with given mods. This argument is ignored when -replay is used. -mods=AT will trigger cursordance with replay UI.
• -skin - overrides Skin.CurrentSkin in settings
• -cs, -ar, -od, -hp - overrides maps' difficulty settings (values outside of osu!'s normal limits accepted)
• -nodbcheck - skips updating the database with new, changed or deleted maps
• -noupdatecheck - skips checking GitHub for a newer version of danser
• -ss=20.5 - creates a screenshot at the given time in .png format
• -quickstart - skips intro (-skip flag), sets LeadInTime and LeadInHold to 0.
• -offset=20 - local audio offset in ms, applies to recordings unlike Audio.Offset. Inverted compared to stable.
• -preciseprogress - prints record progress in 1% increments.

Since danser 0.4.0b artist, creator, difficulty names and titles don't have to exactly match the .osu file.

Examples which should give the same result:

<executable> -d="Overdrive" -tag=2 //Assuming that there is only ONE map with "Overdrive" as its difficulty name

<executable> -t="Brain Power" -d="Overdrive" -tag=2

<executable> -t "Brain Power" -d Overdrive -tag 2

<executable> -t="ain pow" -difficulty="rdrive" -tag=2

<executable> -md5=59f3708114c73b2334ad18f31ef49046 -tag=2

<executable> -id=933228 -tag=2

Settings and knockout usage are detailed in the wiki.

Building the project

You need to clone it or download as a .zip (and unpack it to desired directory)

Prerequisites

• 64-bit go (1.19 at least)
• gcc/g++ (Linux/Unix), WinLibs (Windows, TDM-GCC won't work, mingw-w64 is outdated)
• OpenGL library (shipped with drivers, libgl1-mesa-dev when building on Linux servers)
• xorg-dev, libgtk-3 and libgtk-3-dev (Linux)

Building and running the project

First, enter the cloned/downloaded repository.

When you're running it for the first time or if you made any changes type:

go build

This will automatically download and build needed dependencies.

Afterwards type:

./danser-go <arguments>

Running without arguments (as opposed in Running Danser) will give you the launcher, though you can't use drag&drop on the executable to preload a replay. If that ability is desired, build danser using dist scripts.

danser-go's Issues

nice update

Thanks for your hard work. I've been waiting for this so much!

Option to Render to .mp4

Using ffmpeg to render stuff to a video file would probably work better than real-time, that way my pc won't suffer when turning on bloom.

Support of .osr replay playback

runtime error: index out of range [41] with length 3

Describe the bug
Tried to load "859515 K A Z M A S A - Bon Appetit S (Oldskool HappyHardcore Remix) (Short Ver)", resulting in this error right before the first note has been hit by danser or a replay.
Loading another map works fine with danser and replays but not this one.
Every difficulty of the map results in the same error.
I tried to : reset DB like said in other issues, reset config, renaming audio file (because it has a ",").
Same problem with both Linux (Pop OS) and Windows 10
No success.

Logs

knockout branch flag

I am using the flag but danser cursordances as normal. Any fix?

Few questions about danser

Hello! I love your work! But I have a few questions about it.

1. Whats about the replay functionallity (multiple replays together). Is this already in the program (In the code are some spots which are seeming to do this)
2. Whats about the "kockout"-Mode (like on your YouTube channel).
3. I think I have a small problem with the bot / the resolution (1920x1080) There are no borders, everything is hard zoomed in and the cursors are going out of the screen (unlike in your videos, where they are bouncing on the "walls")

I'm happy you are working on it again! I'll hope we can see even more features comming!

Add Multiple Dansers to knockout

It would be really cool if you could have multiple danser bots in knockouts. Some can use mods.

"no go files in directory" (mac)

[user@computer] ~ % go get -u github.com/wieku/danser
package github.com/wieku/danser: no Go files in /Users/[user]/go/src/github.com/wieku/danser
[user@computer] ~ % cd ~/go/src/github.com/wieku/danser/
[user@computer] danser % go build
can't load package: package github.com/wieku/danser: no Go files in /Users/[user]/go/src/github.com/wieku/danser

Danser cannot find beatmap

Hello, I did download binary from releases
My osu directory is on other disk partition so i create link to
C:\Users\home 3\AppData\Local\'osu!'\Songs

Is this can't detect symbolic folder (since i just sym it to other)?

knockout mode issue?

Hello, and sorry for opening new issue. Is it issue or something?
if it is not, then how to display knockout mode like you: https://www.youtube.com/watch?v=8Lz2ABkKTLc

I typed like this,

and it plays solo.

GUI song select

Osu-like GUI for selecting which beatmap to do (each of which would essentially run an auto-generated command-line for each of said beatmaps).

Very long sliders (especially glitched on Aspire maps) cause update thread freeze

Add partial searches

I just recently downloaded this bot just for fun, I am not an avid osu player and I recently installed osu just to test it cause this bot is interesting. I followed the instructions correctly word for word and their parameters but I keep getting stuck in this error. It should have probably been up and running but it isn't.

I checked where was it located but I don't think I have made any mistakes.

I am confused by that error, I would very much like a GUI to simplify things rather than CLI cause it's tedious to open command prompt and type all the required parameters which is susceptible to typos.

Open and auto close

So, i am opening danser and i open it, then it closes automatically, is there something wrong?

Game resolution is wrong after the first startup

so like the title says, some of the circles are outside of the 1920x1080 fullscreen and idk how to fix that

panic: runtime error: index out of range

Knockout Mode with SS or Quit

As the title says, would be cool if players got knocked out if they hit an 100 or 50 or dropped combo.

How do i add beatmaps?

When i start danser-go it shows no beatmap specified? i don't know how to fix this

Its not working :(

When I try to open it the tab opens for a sec and then closes. can someone help me?

Add custom directories for maps

It only searches on C:\Users\x\Appdata\Local\osu!\Songs

Fading out is broken on maps that ends simultaneously with music

Background images bigger than app's resolution have wrong scale

Is the project getting resurrected?

The project seems to have been getting attention again with the spike in issue activity, does this mean that it will get new features?

Option to automatically close window after ending

It'd be great if there was an option to automatically close the danser window after the song ends.

(MAC) danser-go will open with no window, and then close.

done correctly, but instantly exits

I entered everything correctly, but when it actually starts, it goes fullscreen and then exits shortly after. Is there a fix to this or is there none since this is abandoned?

Bad database

After adding a beatmap with 0 timingPoints to the database; Empty field in timingPoints.
We assume that there are timingPoints as every osu map is required to have a minimum of 1 timingPoint to set the BPM, sliderSpeed, etc.
These entries will throw out of index error when loaded during the database search.
This is more common then expected as osu! leaves behind empty (0b) beatmap files if a beatmap difficulty gets abandoned in an update. This will cause database values to be default or empty, and for the timingPoints this is empty.

Add GUI

Trouble with error: No beatmap specified, closing...

Hello sir, I like your project and I wanted to run this but... there's problem:

No beatmap specified, closing...

I think there's no problem. Here are pictures:

Stops read dir in config

Hello! I found out that if I start beatmap from local dir (where .exe is contains) it works ok. But if I start from cmd (Win+R) and write full path the game starts search in standard folder

I also found out that Russian symbols aren't the reason.
My osu dir is D:\osu!

Knockout Mode Idea

It could be cool to have a knockout mode where the players get knocked out when they're 0hp (usually on multi replays). And maybe, another mode that works the same but the players come back when they're not longer dead.

Lighter sliders

Current sliders are quite heavy, triangle count is pixelLength*(PathLOD/100)*SliderLOD. The new slider algorithm will result in 5 times less triangles in the mesh.

X replays

I heard about this in the comment section of your videos, and I was wondering if that was public yet or im just looking in the wrong spot.

Visual miss bug

Describe the bug
A clear and concise description of what the bug is.

Auto, despite getting a 100% play, appeared to miss in a dancer replay with the DT mod applied.

Screenshots
If applicable, add screenshots to help explain your problem.
this zip should have all you need in terms of visual proof.

Doesn't handle apostrophies?

Most songs I've run into that have an apostrophe in either the title or difficulty are just impossible to get to run. It always comes back with a beat map not found even though I've copy and pasted the name directly into the tag. Weird bug, and because I have no idea how go works I have no idea how hard of a bug it is to fix.

beatmap search by id

I guess this is an enhancement but would it be possible to add a search filter by beatmap id, such as id=123456 instead of having to type out the name of the beatmap as well as the difficulty etc. I've never used github before so sorry if this is in the wrong section.

Relax replay

Replays in relax do not work as danser needs to see a keypress, I think it would be nice to have a check for relax and make it behave like relax.

Wont open

Yup. when I open it the command promt appears then just instantly closes. :////
