Arcaea Chart Note Counter Library

A really simple Arcaea chart note counter library written in C#.

Last updated for Arcaea v6.0.3.

How to use

Simply call one of the following two static methods:

static int Moe.Lowiro.Arcaea.Chart.CountNote(string path);

static int Moe.Lowiro.Arcaea.Chart.CountNote(System.IO.Stream stream);

Notes about compiling

Do NOT check "Code Optimization" in the Project Properties. It will affect floating point errors.

Example

This is an example of using this library to count the notes of all charts and saving the results as CSV.
