HD is ignored in simulate command for taiko and catch #153

Closed Cyan903 closed 8 months ago

Cyan903 commented 2 years ago

150 fixes HD for std:

osu

But taiko and catch still don't show hidden. taiko catch

It isn't just visual either, the pp is calculated as if the score didn't have hidden enabled.

I encountered this also earlier today, and found it's also ignored for mania. It's caused by this: https://github.com/ppy/osu-tools/blob/504f24ed724c98d25e77d031c2c6bf1002d3c623/PerformanceCalculator/LegacyHelper.cs#L83-L87

I believe the reason #150 fixed #149 is because HD became a difficulty adjustment mod.

Mods shouldn't be ignored for PP calculation at all.

Cyan903 commented 2 years ago

Not sure if I should open another issue, but I did some further testing and it seems that it isn't just hidden, multiple taiko mods aren't calculating properly.

Using this map as an example:

For HR:

dotnet run --project ./PerformanceCalculator/ -- simulate taiko 2892205 -a 100 -c 490 -X 0 -m hr
# pp: 300.91

Output: https://pastebin.com/hQmGrqNU Yet comparing that to a score set on bancho, there is nearly a 20pp difference.

For DT:

dotnet run --project ./PerformanceCalculator/ -- simulate taiko 2892205 -a 99.08 -c 490 -X 0 -m dt
# pp: 485.60

Output: https://pastebin.com/y0qyKchu Compared to another bancho score, a difference of 103pp.

For FL:

(2892205 didn't have any FL plays so I'm using this as an example)

dotnet run --project ./PerformanceCalculator/ -- simulate taiko 1519305 -a 99.52 -c 943 -X 0 -m fl
# pp: 304.29

Output: https://pastebin.com/Dptwvc5A 15pp diff from here. Also FL is being ignored as a mod here.

EZ, NF, and HT also have a difference, but it's usually in the single digits so I don't think it's a huge deal. HR is mostly functional with it only being around 20-40pp off. It's mainly DT, HD, and FL that have issues. I tested all of these on the latest commit which was 9 days ago at the time of writing this.

Diffcalc/ppcalc is constantly evolving and this tool (for the most part) tracks the most recent changes. https://github.com/ppy/osu/pull/18208 was merged since the last deploy which is included in the latest master.

There are still some differences (<5pp from my testing) and those could come down to any non-diffcalc fixes that happened in the last however-long-it's-been-since-deploy that could have affected things (e.g. fixes to beatmap parsing). Or it could be related to sometimes ppcalc on osu-web just misses scores - I forget the exact cause.

What I can tell you with certainty though, is that the current changes in master match the current osu-performance on those scores.

The only ones of relevance that don't match are FL, HD, and NF, because those mods are skipped via the same reasoning as above.
