One example implementation of this library is MaichartConverter, which converts between Simai and Ma2. Please see MaichartConverter for more information.
git clone
dotnet build
- The most basic part of this is
Chart. You can use this base class to construct different charts. - This library follows the Tokenizer-Parser-Compiler format to process files, and uses an Abstract Syntax Tree for
grammar
decomposition when implementing Simai and Ma2 formats. If you wish to add additional formats, please make sure you
also process files in the same fashion as this library, and ensure that all methods within
the
ITokenizer,IParser, andICompilerinterfaces are properly implemented. - The
Chartbase class is an intermediary in order to achieve inter-format compatability. If you are adding a new format, please be sure to also create a class implementing this base class. TheChartclass has already implemented the functions you need for a maimai chart, and you only need to implement several abstract methods in that class to fit your format. - Then, you may create a maimai chart instance in your code. For example, creating a Ma2 chart can be done
via
Chart ma2Chart = new Ma2();.
- As always, I think Simai is a language more focused on charting rather than interpreting. I still have no idea why there isn't a UI-based charting tool. Instead we have to learn this unsecure and unintuitive language, especially after Festival added new features. This makes interpreting Simai a huge PAIN since the way it converts between ticks and times is vague and honestly unreasonable.
- For example, it defines a Slide note as having a wait time of 1 beat or one 1/4 note (or a crotchet for those in the music community) after its start tap. If your Slide note starts longer or shorter than 1 quaver of the current BPM, you will have to: a) change the BPM for that specific Slide or b) define the time by [wait time##last time] (and calculating that is extremely time consuming).
- I hope someone develops a language better than Simai to use as a intermediate language between coding and charting. Thank you.
- music files should be named
musicxxxxxx.mp3, where 'xxxxxx' matches the music ID specified inmusic.xmlin each a000 folder. Please make sure to add 0s at the front of this so that it contains 6 digits - bga files should be named
xxxxxx.mp4which matches the music ID specified inmusic.xmlin each a000 folder. Please make sure to add 0s at the front of this so that it contains 6 digits - image folders should be structured in
image/Texture2D/and the files should start with 'UI_Jacket_xxxxxx.jpg', where 'xxxxxx' matches the music id specified inmusic.xmlin each a000 folder. Please make sure to add 0s at the front of this so that it contains 6 digits - The difficulty parameter is listed 0-4, from Basic to Re:Master. In MaiLib, I specified rules for Easy and Utage but it takes time for me to figure it out, or you could implement it on your own, referring MaiLib code
- All paths, reguardless of operating system, should end with a path separator like "/" or "". Do not include the quotation marks in the path.
- If you have difficulty using the commands, please refer to
VSCode launch.jsonwhere I included several examples. - The whole program was initially planned to convert from ma2 to simai, and all other features were developed after that, so there is a HUGE amount of compromises in the code's design which makes it hard to read (but works so far). It would be most kind of you if you could help me in fixing that.
