Beatmap Format

I've tweaked the format since SIF Train into something more simple.

First Block: metadata

fields:

• songName: the name of the song, UTF-8 encoded
• songFile: the name of the music file (may or not be present in the soundfiles folder) without extension
• composer: self-explanatory
• lyricist: self-explanatory
• id: required - must be a unique number, It's encouraged to use numbers above 100000 to avoid conflicts with the files from my other repo
• difficultyName: the name of the difficulty
• difficulty: the difficulty rating (in stars)
• attribute: the attribute of the song (0: TUTORIAL, 1:Cute, 2: Cool, 3: Passion, 4: All)
• bpm: the bpm of the song
• duration: the duration of the song (if a soundfile isn't present, this value will indicate the end of the song. I recommend setting this value to the time of the last note + 5 seconds)

Second Block: notes

fields:

• id: the id of the note, is unique within the song.
• timing: the time at which the note should be hit
• type: the type of the note (1: normal, 2: hold)
• startPos: the spawn position, (1-5) (unused)
• endPos: the end position (1-5) (unused)
• status: the kind of note (0: no-swipe, 1:swipe-left, 2:swipe-right)
• sync: flag which indicates whether two or more notes are played at the same time
• groupId: if notes are swipes, they can be grouped together by the groupId
• nextNoteId: swipes or holds need info on which other note they're linked to for correctly drawing the beams / processing hit/miss
• prevNoteId: back-reference to the previous note in a hold or grouped swipe combo
