Make PGUp / PGDown change speed modifier of mods #28071

Fabiano1337 · 2024-05-02T17:55:00Z

PageUp and PageDown now increase or decrease speed in song select.

Example
(Song Select screen and no mod is selected)

Page Down is pressed
HalfTime mod gets applied with 0.95x speed modifier
Page Down is pressed again
HalfTime mod speed modifier changes to 0.9x
same goes with PageUp and DoubleTime.

If Daycore or Nightcore are currently selected it increases those.
If the minimum rate gets surpassed Half-/Double-Time get applied

Im open to any suggestions for changes and i hope this feature finds its way into osu!lazer

What is the reason for wanting this?
Why should DT/HT get preferential hotkey treatment for their settings over every other mod in the game?
Was this feature discussed anywhere at all before this PR?

What is the reason for wanting this?
It is a quality of life feature that makes adjusting the speed of your map faster (useful for people who often push their limits and increase the speed every run of a map), with this implementation you can adjust speed the using only your keyboard.

Why should DT/HT get preferential hotkey treatment over every other mod in the game?
DT/HT are some of the most used mods in the game, HR/HD don't have any adjustability. HR and HD can be fully utilized with only a keyboard whereas DT/HT cannot. DC/NC are lesser used than DT/HT which is why i opted for DT/HT, this is up for debate tho.

Was this feature discussed anywhere at all before this PR?
No, i haven't seen this feature being discussed anywhere before, since isn't that big of a feature i thought it didn't need one. Do you want me to open a Discussion about this topic first ?

longnguyen2004 · 2024-05-02T18:33:30Z

(Not lazer dev, just my opinion) The hotkey for this cannot be PgUp/PgDown, since those are used to scroll the carousel, and I also don't like the semantic of PgUp/PgDown being changed like that, since those keys are almost always used to scroll, and not to adjust a setting. Maybe Ctrl+Up and Ctrl+Down?

I generally prefer all unsolicited feature requests to go through discussions first in order to reduce wasted contributor effort and to gauge interest in the feature. At this time I have no idea as to whether anyone but yourself wants this feature to exist.

UX-wise I have a whole mess of doubts.

As stated above this should not use page up/down by default.
If you manually select daycore and then page-up enough to progress into track speed-up I'd probably expect nightcore to be activated. Right now double time activates.
If you manually change "adjust pitch" on DT/HT and then page-up/down enough to progress into HT/DT then mod setting is lost. It should probably be preserved.
It's not very clear what's happening if you press the binding but don't look at the footer. This gets especially weird if you e.g. speed up DT from 1.45x to 1.5x because the speed indicator on the right of the right of the mod icon in the footer disappears. I'd say there should be a toast or something showing what's changing.

Not to mention something like wind up/down that also have speed adjustments but don't get any special hotkeys.

Missing unit tests

osu.Game/Screens/Select/SongSelect.cs

+                case GlobalAction.IncreaseSpeed:
+                    increaseSpeed();

+                    decreaseSpeed();
+                    return true;


increaseSpeed() and decreaseSpeed() should probably be one method that accept a delta or something.

+            bool rateModActive = ModSelect.AllAvailableMods.Count(pair => pair.Mod is ModRateAdjust && pair.Active.Value) > 0;


These should not be doing mod queries or mutations via ModSelect. Use selectedMods and OsuGameBase.AvailableMods instead.

+
+            // Find current active rateAdjust mod and modify speed, enable DoubleTime if necessary
+            foreach (var state in rateAdjustStates)


This should be asserting that there is only one rate adjust mod present rather than doing some weird loop.

I created a Discussion about this feature.
#28085

bdach · 2024-05-14T06:51:39Z

I guess the discussion seems to have gathered some support, but I'd still expect the review above to be addressed for this before this can be considered further.

Fabiano1337 · 2024-05-14T07:02:01Z

Sure,
since i still have school and stuff going on it could take me maybe a week or two.
Im currently trying to enable the mods without using ModSelect, i can't just add new mods to selectedMods since thats a readOnlyList right ?

bdach · 2024-05-14T07:12:42Z

You can replace the entire list.

Nightcore now switches into Daycore, keep Adjustpitch after change

Fabiano1337 · 2024-05-18T16:49:18Z

Do we add support for holding the button (for example every 500ms speed increases) or do we keep it like it is now that you have to press the key again ?
You mentioned a toast showing that something is changing, do you have any idea on what that could look like ?

This would already be supported if not for this early return:

osu/osu.Game/Screens/Select/SongSelect.cs

Lines 1138 to 1139 in 3fdbd73

    
           if (e.Repeat) 
        
               return false;

You mentioned a toast showing that something is changing, do you have any idea on what that could look like ?

Use the existing one. See usages elsewhere on how to display it.

Fabiano1337 · 2024-05-21T14:53:47Z

Seems like the toast implementation 148afd1 makes the test fail, locally they still run fine on my side

Edit : Tests fail because the SpeedChange value of RateAdjustMods are not exactly 0.95

Before I gave up on attempting to fix the method.

This method needs a rewrite.

Could you tell me what needs to change for the rewrite so i don't do the same mistake again? (more readable, more compact, ...)

This probably should actually show the speed?
