Constructors

constructor

  • new Kinetic(decay, minVelocity, delay): Kinetic

  • Parameters

    • decay: number

      Rate of decay (must be negative).

    • minVelocity: number

      Minimum velocity (pixels/millisecond).

    • delay: number

      Delay to consider to calculate the kinetic initial values (milliseconds).

    Returns Kinetic
