In this project we are going to discuss how is a taiko map be rated by star difficulty, how many star should a map be.

Background

1. People argue on difficulty star rating, and because different player have different skill so they may think different towards a map

2. The star show in osu do not having meaning to taiko.

Aim

1. Find the actual difficulty of a taiko map, showing that by a number called "Difficulty index". This allow us to directly compare maps.

2. From the index, we can judge the difficulty name of the map. This mean when we get enough data, we can set up lines as if the index is higher than x , that map should be inner oni.

And here are some factors discussed by those big guys like ono and aabc.

1. Stream length, how many streams are there in the map. Of cause more SHOULD be difficult.

2. Notes complexity, the patten of stream, need to be discussed.

3. Timing Points if you remember who is ishida.......

4. OD, the exact number in the .osu file


Okay I hate typing a lot of useless background.

Now I tell you what you can do to help me!


First make sure you have installed JAVA, just google it if you don't know what is that.

Then download the program on the second post.

Post the result here with following format

Map tested : [Link to the map]
Screenshot of the result : [Link here, the shot of the program result]
The star difficulty you think : [??★ Oni]
Comment : [Explain why you think that map should be that star difficulty]

After collecting enough sample data we can work a final solution to the index

Taiko Difficulty Rater v0.3

Download Link Here

How to use

1. Download and extract the file

2. After you run the TaikoRater.exe , you will see a pop up which ask you to select a file. Here you can go to select the map file (.osu)

3. Remember to check every word in the program before you continue!!

4. Screen shot that result

Problems still need to be solved


1. Map with BPM change, or directly said, map with more than 1 red line

2. Notes complexity is not the final version, you have to submit some sample result here to make it final

3. GUI , I will design that later

What does the result tell


Sample result :


Title balabala, whatever, the same as in the file

Total notes : Notes counter which just counter the total number of notes, does not count silder and spinner

Density : Notes per second(NPS) . This number is total note/total time. And as far as I know, 4-4.9=muzu, 5-6.7 =oni, 6.8-9=inner

HP and OD : whatever

Notes complexity : a equation designed by me to find that, may be not so accurate

Stream length : Total number of notes which are in stream, no matter xx , xxx , xxxx, or even 100stream. And if you use total notes - this number you can find that how many single notes are there

Wow it'll be pretty awesome if this gets implemented :D

Good job,
keep collecting samples in this way
Analysis can be done later

Also, the algorithm should be used as an indicator only.
The star rating should be rated by human in the end.

I will make the program okay for bpm change later.....I know the way but it is really tiring

The star difficulty you think : [24+★Ura Oni] It's harder than the previous map
Comment : 224 1/4 with 1/8 streams + SV

Star diff: 19☆ Oni
Comment: superdense stream, 250 bpm, speedups at the end making it tough to play in 4:3
side comment: I passed THIS?

mind if you give me the source code ?

Star Rating: 13☆ Oni
Comment: Various pattern by the same/similar background music, low BPM is however not that hard to pass/fc.

Doesn't work. Probably related to an older java version but sadly I don't have the admin rights on this PC to fix that. ;_;

Screenshot of the result:

Star rating: 9☆ Oni
Extra comment: BPM is not too low but not too high either (160), some long streams which are quite simple to deal with, with the occasional complex shorter stream. Overall I'd say it's just a meh Oni, but it does get harder as it goes along.
side comment: why can't I fc it? ;~;
