Methods

calculate

  • calculate(params?: { isForceAR?: boolean; mode?: modes; mods?: string; speedMultiplier?: number }): MapStats

  • Calculates map statistics.

    This can only be called once for an instance.

    Parameters

    • Optional params: { isForceAR?: boolean; mode?: modes; mods?: string; speedMultiplier?: number }
      • Optional isForceAR?: boolean

        Whether force AR is turned on.

      • Optional mode?: modes

        The gamemode to calculate for. Defaults to modes.osu.

      • Optional mods?: string

        The applied modifications in osu!standard format.

      • Optional speedMultiplier?: number

        The speed multiplier to calculate for.

    Returns MapStats

toString

  • toString(): string

Static arToMS

  • arToMS(ar: number): number

  • Converts an AR value to its milliseconds value.

    Parameters

    • ar: number

      The AR to convert.

    Returns number

    The milliseconds value represented by the AR.

Static modifyAR

  • modifyAR(baseAR: number, speedMultiplier: number, statisticsMultiplier: number): number

  • Utility function to apply speed and flat multipliers to stats where speed changes apply for AR.

    Parameters

    • baseAR: number

      The base AR value.

    • speedMultiplier: number

      The speed multiplier to calculate.

    • statisticsMultiplier: number

      The statistics multiplier to calculate from map-changing nonspeed-changing mods.

    Returns number

Static modifyOD

  • modifyOD(baseOD: number, speedMultiplier: number, statisticsMultiplier: number): number

  • Utility function to apply speed and flat multipliers to stats where speed changes apply for OD.

    Parameters

    • baseOD: number

      The base OD value.

    • speedMultiplier: number

      The speed multiplier to calculate.

    • statisticsMultiplier: number

      The statistics multiplier to calculate from map-changing nonspeed-changing mods.

    Returns number
