Class Track

constructor

• new Track(): Track

  Returns Track

keyFrameCount

keyframesOffset

ledMask

equals

• equals(other: Track): boolean

  Compares two Track instances.

  Parameters

  • other: Track

    The Track instance to compare with.

  Returns boolean

  Whether the two Track instances have the same data.

evaluate

• evaluate(
      bits: AnimationBits,
      color: number,
      time: number,
      ledCount: number,
      retIndices: number[],
      retColors32: number[],
  ): number

  Evaluates an animation track's for a given time, in milliseconds, and fills returns arrays of led indices and colors. The returned colors are the given color modulated with the light intensity of the track for the given time. Values outside the track's range are clamped to first or last keyframe value.

  Parameters

  • bits: AnimationBits

    The animation bits with the keyframes data and color palette.

  • color: number

    The color for which to modulate the intensity.

  • time: number

    The time at which to evaluate the track.

  • ledCount: number
  • retIndices: number[]

    Array of LED indices to be updated.

  • retColors32: number[]

    Array of 32 bits colors to be updated.

  Returns number

  The number of LED indices that have been set in the returned arrays.

evaluateIntensity

• evaluateIntensity(bits: AnimationBits, time: number): number

  Evaluates an animation track's for a given time, in milliseconds. Values outside the track's range are clamped to first or last keyframe value.

  Parameters

  • bits: AnimationBits

    The animation bits with the keyframes data and color palette.

  • time: number

    The time at which to evaluate the track.

  Returns number

  The modulated color.

extractLEDIndices

• extractLEDIndices(retIndices: number[]): number

  Extracts the LED indices from the LED bit mask.

  Parameters

  • retIndices: number[]

    Array of LED indices to be updated.

  Returns number

  The number of LED indices that have been set in the returned arrays.

getDuration

• getDuration(bits: AnimationBits): number

  Gets the track duration.

  Parameters

  • bits: AnimationBits

    The animation bits with the keyframes data.

  Returns number

  The track duration.

getKeyframe

• getKeyframe(bits: AnimationBits, keyframeIndex: number): SimpleKeyframe

  Gets the data of the keyframe at the given index.

  Parameters

  • bits: AnimationBits

    The animation bits with the keyframes data.

  • keyframeIndex: number

    The index of the keyframe.

  Returns SimpleKeyframe

  The keyframe data.
