Work

• [x] Get audio for inspo
• [x] Design data structure
• [x] Implement attaching meta of the song with the data structure
• [x] Implement playing song via Chart metadata
• [ ] Figure out dynamic timing (base it on osu)
  • Try to figure out the beat of the song maybe through a website: https://tunebat.com/Analyzer
• [ ] Figure out how to chart the song
  • [ ] How to place a beat
  • [ ] How to replay the song
  • [ ] How to place two beats at once
  • [ ] How to place a slide
  • [ ] How to place a hold
  • [ ] How to place a hold and a curve
  • [ ] How to adjust the curve

Chart Structure

Reference: https://osu.ppy.sh/wiki/en/Client/File_formats/osu_(file_format)

ChartMeta

• SongName: string
• AudioFilename: string
• TimingPoints
  • Time: integer = start of timing section
  • BeatLength: float = the duration of a beat in milliseconds
    • If BPM = 132; then BeatLength = 60 000 ms / 132 BPM = 454
    • 60 000 ms / x BPM = BeatLength
  • Meter: integer = amount of beats in a meter
• HitObjects
  • Timing: ulong = time to react to the object from the beginning of the song
  • Y: integer = location across the direction that the beats are moving
  • Type: integer enum = type of hit object, see HitType
  • Channel: integer = relevant to hold, tells which of the holds are connected
  • HoldCurvePriority?: boolean = if there are two hold channels active, prioritize the one with this property set as true
  • BezCurveStart: Vector<2D> = the position of the handle of the bezier curve from the start. If the beats are moving left to right, this would be the position to the right.
  • BezCurveEnd: Vector<2D> = the position of the handle of the bezier curve from the end. If the beats are moving left to right, this would be the position to the left.

Note:

• We might have issues with different screen resolution when it comes to the BezCurve

HitType

• -1 Unknown
• 0 Unmarked
