Viv 35ee48200f `converters.py`: Only subtract drumroll pos for single-measure drumroll Commit `1953ffbc23` fixes one issue but introduced another: - Subtracting the drumrolls original position only makes sense if the drumroll starts and ends in the same measure. - If the drumroll spans multiple measures, though, then the original position is irrelevant, since we want to add the duration from the start of the next measure (i.e. pos=0). So, this commit makes sure to only subtract the position if the drumroll isn't a multi-measure drumroll. ((NB: This could probably be handled without using a new 'multimeasure' key, but I'm going to wait until the class refactor to tackle this.)) Fixes #16.	2023-06-03 14:57:11 -04:00

tja2fumen

This repo a new attempt to write a tja2fumen chart converter to replace/complement the existing tja2bin.exe converter.

Goals

Fix desyncronization issues due to BPMCHANGE commands. (See: https://github.com/Fluto/TakoTako/issues/16)
Provide open source code, as opposed to distributing only a closed-source binary.
Provide a highly-documented reference for parsing both the TJA and Fumen file formats.
Stick to "pure Python", i.e. no external dependencies if possible.
Provide support for Windows/Linux/macOS via PyInstaller or something similar.

Usage

The converter is in a messy/experimental state, and is not yet fit for use due to lack of support for important TJA commands.

Attribution

The fumen-parsing code in this project is based off of a modified copy of the readFumen() function from the fumen2osu.py found in @KatieFrogs' fumen-tools project.
The TJA-parsing code in this project is a Python translation of the parseTJA.js file from @WHMHammer's tja-tools.
