Proposal 43254

Add a mirror mod in the game while also making any plays with mirror mod (if added) to be counted as a ranked score.

Why mirror ?
Flipping the map horizontally allows players to by any hand bias within the map. Standard already implemented a similar concept with the Hard Rock mod, so technically it can be applied to mania as well. Along with standard having Hard Rock, mania already has a similar mod, Random, which shuffles the notes each time when you play, but Random is unrankable due to the possibility of the predicted difficulty to be... well, random thus having an inconsistent difficulty. Mirroring is essentially Random, but a consistent one, thus the difficulty is also consistent.

Wouldn't this affect a chart's quality (especially in of Pitch Relevance) ?
Not at all. Most maps do pitch with the first column being the lowest pitch while the last column being the higher pitch. If we were to mirror it, the first column would be the highest pitch while the last column would be the lowest pitch, so chart quality isn't affected at all due to the map still being relative to the pitch of the song.
In general, mirroring a map shouldn't affect a chart's quality whatsoever.

What would the mirror mod do ?
Simple, it mirrors the entire map horizontally.
For 4K, columns 1 and 4 are switched, and columns 2 and 3 are switched.
For 5K, column 3 would stay as is, columns 1 and 5 are switched, and columns 2 and 4 are switched.
For 6K, columns 1 and 6 are switched, columns 2 and 5 are switched, and columns 3 and 4 are switched.
For 7K, column 4 would stay as is, columns 1 and 7 are switched, columns 2 and 6 are switched, and columns 3 and 5 are switched.
(you get the gist by now)

Why would mirror mod be beneficial ?
There are ranked and/or loved maps that have a certain hand bias that favours certain players while also giving certain players a disadvantage. Though this is not necessarily noticable for players below rank 5000, it is much more noticable for players that are higher ranked. This would also be beneficial for any tournaments as well. Rather than determining a match purely on whoever's singular hand is better on this map, it grants both players an advantage which then the match is determined by purely whoever does better and not some other physical aspect. There are also certain patterns that players mindblock where it's simply unplayable to them no matter how difficult or simple the pattern may be. Players shouldn't be told to just "play better" when the map is biased against them. Thus, mirror mod shouldn't grant any bonus towards score or performance points, but it should still count as a ranked score.

Edit: I am aware of the other forum posts that requested a mirror mod before especially the one created by chaotic_iak on here. However, decided to create a new forum post primarily because 1. It has been 3 years since that topic was responded to and 2. It is more relevant nowadays especially with the shift in mapping (and you can kinda tell it's more relevant now based off of the number of replies within the first few hours alone) and 3. The old forum doesn't seem to have a clear reason as to why having a mirror mod is beneficial.

this was discussed years ago with regards to how 7+1k is charted and I see this as something that should've been done YEARS ago so yes

EDIT: also it's already in lazer so why not add it to stable
EDIT 2: besides there are already ways to play with mirrored patterns that involve flipping your screen and reversing your binds so why not just make this an actual mod like every other keyboard rhythm game in existence does?

>it's already in lazer

watch as it gets denied for a bullshit reason like that by devs

Kamikaze brings up valid points and following Kasumii-sama, we have never gotten a specific eta on osu!lazer so it may be more years before the game is actually complete. You may as well apply it to Stable so that it can be used for any mania-related events until osu!lazer is released.

oh hell yea

EDIT 4: we did it bois

If there are any other addition or errors to this, please let me know so that it can be fixed on this post.

OH MY GOD YES

this is cosmic brain. i like it

I see this as an absolute win

Love the idea! I definitely this

MIRROR is a very important feature in some other key-based rhythm games that helps player who are better with one hand than the other moving the strain of some intense parts of the map to the dominant hand.
This is considered fair and as valuable as a score made without using the MIRROR mod in those games because the columns being in right-to-left or left-to-right order isn't supposed to change difficulty at all.

I'm totally for this being added to osu! AND for it being a rankable mod that doesn't change the pp, score or difficulty of a map at all.

Take all of my stars

i guess

make osu!mania great again

niceee

This is actually soo good, i totally agree with this

Don't know why this wasn't implemented years ago, I Stan this post

How does this topic get 1000 SP and 130 votes in just two hours

because of jakads

This is a great idea, I'm sick of mindblocks.

Also, why is there still not a way to promote these without manually clicking "Promote this request" 100s of times?
Not only that, it's telling me that I'm making too many requests and gives me an error every so many times.

Please donate 40 stars to help the Wagg Galaxy Collapse mindblock

100% yes.

ohmygod PLEASE I CAN FINALLY UNMINDBLOCK UTA

It's about time Mirroring is finally brought up in o!m 👍

PLEASE BE ADDED 🙏🙏🙏

How can we deny this

why not from long ago
should put it since first

truly

Finally something good!!

maybe in 10 years will have rate options lol

lmoa

not adding mirror is class betrayal

unrelated to mania but could we add this to taiko as well? blue notes become red, red becomes blue

Finally

Yes

Plz

GO

LET'S GET MIRRORED

As i have a motor problem on my right hand due to a surgery, this would help me a lot

I actually asked the same thing here like 1 year ago. Someone actually wrote the code and Lazer WILL have a Mirror Mod.

However, seeing it on stable would be real awesome.

https://twitter.com/ppy/status/1169089044195598336

Shame that it dies down so quick.

Maybe we should get ourselves mindblocked for every hand-biased patterns in specific charts.

please add yes?

Last mod will be mirror mod, absoluty

ppy dismiss this


R.I.P. mirror mod

yes

lol

will this mod be ranked?

You guys are much, much better off implementing the feature into osu!lazer.

Create an issue regarding it here: https://github.com/ppy/osu/issues

Then have someone code it up and create a pull request.

Most feature requests in these forums is are not likely to see the light of day for several more years at the very least.

If you think this will be added into stable, then sorry to disappoint. All development is focused on lazer which will supersede stable. So it's counterproductive for the devs to spend time adding it to stable.

This is actually already implemented in lazer!

Guess that's a custom mod, because I can't find it in options nor in mods

edit : nvm, apparently you can scroll in the mods... git issue openned to actually let us know you can scroll

This has now been implemented and is live in CuttingEdge. Let us know if there are any issues with it.

it's taken how many years for this?

Technically, one day.

awesome. glad this is actually a thing now. thanks smoogi

God bless

yess plss, i need this

Finally something good for the community

We did it reddit

Marked as added. Enjoy Mirror Effector.

this is actually a godsend and i love it so damn much

Problem Details:

Playing mirror mode on 6k or 8k moves the special key column. This happens on maps using special style N+1, as set in the editor.
To fix this, the player have to switch the special key position in his mania layout configuration. Sometimes, he has to adapt his skin.

Expected behavior:

Special key column must not be affected by the mirror mod. Here's an example with 7K+1.

If using special style (left), column 1 must not move. Instead:
- Switch column 8 with column 2.
- Switch column 7 with column 3.
- Switch column 6 with column 4.
- Column 5 remains unchanged.

If using special style (right), column 8 must not move Instead:
- Switch column 7 with column 1.
- Switch column 6 with column 2.
- Switch column 5 with column 3.
- Column 4 remain unchanged.


osu! version: 20190906.1

I think that the Mirror Mod shouldn't change the position of the special column.

if it's not a reported issue on here, it should be: https://github.com/ppy/osu/issues
