Any time a map has a slider or spinner, any circles (and maybe sliders) that are meant to be tapped during that slider/spinner's duration don't respond to being tapped at all, resulting in the note being forcibly missed.

Now for some reason when i process too many beatmaps it crahes without forgetting the fact that it takes so long to process them each time two times .optimizating it or finding an alternate for the beamap proccesing would be good so that it goes faster and be optimized.

This has been an issue for awhile and has only been slightly fixed by capping the amount to 30 and distributing it (previously it would render hundreds if the follow point image was too small)

For those who arent up to spec on how follow points are rendered in stable and droid
droid: calculate the amount to fill the distance (cap to 30) then distribute evenly
stable: place a follow point every 32 pixels(?) until you reach the end

In the following code block it shows how stable renders its follow points

	internal void AddFollowPoints(int startIndex = 0, int endIndex = -1) {
            if (endIndex == -1) endIndex = this.hitObjectsCount - 1;

            pTexture[] fptextures = TextureManager.LoadAll(@"followpoint");
            
            int followPointIndex = 0;
            for (int i = startIndex + 1; i <= endIndex; i++) {
                HitObject currHitObject = this.hitObjects[i];
                
                //Draw connection lines
                if (!currHitObject.NewCombo && !this.hitObjects[i - 1].IsType(HitObjectType.Spinner) && !this.hitObjects[i].IsType(HitObjectType.Spinner)) {
                    Vector2 pos1 = this.hitObjects[i - 1].EndPosition;
                    int time1 = this.hitObjects[i - 1].EndTime;
                    Vector2 pos2 = currHitObject.Position;
                    int time2 = currHitObject.StartTime;

                    int distance = (int)Vector2.Distance(pos1, pos2);
                    Vector2 distanceVector = pos2 - pos1;
                    int length = time2 - time1;

                    float angle = (float)Math.Atan2(pos2.Y - pos1.Y, pos2.X - pos1.X);
                    
                    for (int j = (int)(FollowLineDistance * 1.5); j < distance - FollowLineDistance; j += FollowLineDistance) {
                        float fraction = (float)j / distance;
                        Vector2 posStart = pos1 + (fraction - 0.1f) * distanceVector;
                        Vector2 pos = pos1 + fraction * distanceVector;
                        int fadein = (int)(time1 + fraction * length) - FollowLinePreEmpt;
                        int fadeout = (int)(time1 + fraction * length);

In the map paraparaMAX I, there are some red lines, which should change the slider velocity since they change the BPM, but the slider velocity remains the same as it is at the beginning. This results in the map being completely broken, as other objects are occurring during slider bodies due to the sliders not completing quickly enough. This demonstrates another issue which will be made in a separate post.

osu droid should have experimental sliders because circles in the game are too big especially if you're using a small phone and it's hard to see and read the notes even if i use a skin, sliders and circle size should be adjustable.

Hello, there! Since Rian told me to open an issue about the bug, I started writing this. Now for the bug. The bug happens usually when you get out of a map right before finishing. When you try to replay the difficulty it automatically makes an SS score without any clicks, combo and score. Some said that the bug is quite well known, but I still wanted to share it here. Link for the video (it occurs in the end): https://youtu.be/P_qjmOFGJgU

I like to play osu with some skins (some older than another) but in all of them have one problem and do "abnormal problem" to osu... but i have some skins what are since 2010, other are like 2018 or 2019 and he have a issue with them...

You can put RX + SD/PF and AP + SD/PF as well as (RX/AP) + NF (I guess this is an old bug) in the latest prerelease.

PF works as intended, however SD completely bugs out. On the other hand, RX and AP already have a "built-in NF", therefore putting NF on both mods is useless.

Perhaps fixing SD behavior on RX and AP and/or making all 5 mods exclusive to each other (like in official osu!) should be considered.

Side note: NF, SD, and PF are already exclusive to each other.

My phone can support 10 simultaneously touch without problem but here at osu!droid it can only register 1 touch and im playing bangdream so multi touch is supported.

The createHitEffect method in GameScene class never processes any kind of animated hit results (normal, katu, geki), however these textures are loaded when the game is loading skins.

Results in this error:

Is there an public api to get the an player stats on the game?

Reported by a user in Discord.

Precise mod is ready to be ranked, there are still some thing to do:

• determine score multiplier (I think x1.05 is fine)

• client side coding

• server side coding

When playing with activated beatmap skins the hitcircle overlays from a beatmap skin do not apply to sliders (neither start or end) and use the global skin instead (happens with default skin and player selected skins). Hitcircles consistently use the hitcircle overlay from the beatmap.

Example maps:
https://osu.ppy.sh/beatmapsets/7205#osu/31412
https://osu.ppy.sh/beatmapsets/355065#osu/781872

This issue should apply to all maps using a custom hitcircle overlay.

As the title, unsightly artifacts will be produced on backgrounds when set to Low brightness, such as during gameplay with high background dim.
This is probably due to the "Use Hardware Dither" function in the game's options not working as intended.
It might be also related to the implementation of the "Set Background Quality" option, regarding color spaces.
osu!droid might have been using 6 or 7-bit color spaces since 1.6.7 which if true, will cause these artifacts.
Fixing the "High" quality background setting to display 8-bit colors might solve this issue?
The differences can be seen below. (All examples are in 25% brightness)

Old droid version:

Screenshot from HAG - Colorful Background by Sotarks

Additional suggestion: Have an option to support 10-bit color spaces since there are phones which support it. (Have an option in Set Background Quality being "Very High*")

in some case those elements disappear, but haven't found why,

read some thing from asset folder, but works like 'values-en/values-zh' in res folder

This formula will break down in CS≥85/7, which is approximately 12.14. The situation can be achieved using SC (small circle) mod in combination with HR in high CS maps such as this. When such cases happen, the hitobject radius will be negative.

The original osu! implementation caps the CS at 10 both in gameplay and difficulty calculation.

Before you create a issue, you should know:

• Main team members can only understand English and Chinese, so please use these 2 languages.
• Do not ask questions about some general topics without any suggestions, otherwise we can't get any extra information because we already know the things you talk about.
• Bug report should be repeatable, and if you get a bug, you should ask for help in discord or qq first, please only issue a new bug.
• An issue with your actual work (such as a pull request that solves your issue) will be helpful, that's most valuable.
• DELETE these lines before you create a issue.

If you are good at java or Kotlin, a pull request is much better than a feature request
We only have a few developers, and most of them are busy. We don't have enough time to implement your feature request. So, if your are good at coding, you can try to implement your feature request youself.

I would like to ask you to change the size of the buttons because they are too big

Could u add more skinnable elements?

Tested in Android 8.0, however multiple users with various Android versions have reported similar issue.

The game needs a option what if i miss a note i can continue without try to just click on the missed note and get a 50 or a miss

Because i like to play maps what have many streams (rubik's cube for example) and when i was doing the streams i lost for literally 1 note what i've jumped... and if be possible hmm fix a problem what it's i can't hit some circles in big jumps idk...so is it :)

Some elements are rendered after info text

I mean, i want to make my own beatmap but theres no editor in the app and i cant see other apps to create beatmaps.

I have a problem when failing a beatmap.
When I press the Back button on my phone, the fail sound doesn't stop. Please fix this!
Here is the video of it!

Hello Osudroid devs.

I just want to say that there is a bug where Sliders & Circles won't respond when a Spinner is in the gameplay. Even if the SliderLock Option exists in settings, it still doesn't work.

I recorded my gameplay of a 2B map as an example for a bug, I wrote everything in the description to explain the bug I've been experiencing.

Same as implementing a SpinnerLock option or merging that request to SliderLock options to the settings.

Link here: https://youtu.be/6mTtHZH5LPM

So like, theres nothing in the GitHub description.

This should be changed in order to give contributors and users a better idea of what this is at first glance, such as saying its an osu! client with extra features and such.

Will open osudroid and it will detect the song in my downloads then import it. I click the play button and then it says "Caching complete. Found 0 beatmaps" and the screen says later "there are no songs in library"

I checked the song directory and the songs i imported are there. They just don't show up in the app

Edit: also the discord link is expired

Can you make a option for play with keyboard please? I need it

#26 : make sure this pull request works well.

Is it intentional that force AR and speed modify modifiers are not stored in replays? Apparently they are only stored in score database file.

I have many friends what play osu and we was thinking if the osu!droid have a multiplayer and the pp (perfomance point), the multi was a good idea for play with everbody together and the pp just for show the points what one people have (that don't have a impact in ur rank).

Multitouch don’t support
Multitouch doesn't work only in Osu Droid, when you start osu droid writes that multitouch is not supported and it doesn't work, but in other games it works great

EDIT: I only tested this with stars sorting option, however another user reported that length sorting option also has this bug.
