# Animation

class `Animation` : public HPS::Sprocket

  The Animation class is used to animate objects in the scene through the creation of one or more Channels. An Animation is owned by a Model, and as such needs to be created through the Model::CreateAnimation function. Animation objects are only valid for playback if they contain one or more Channel objects.

  `Animation`()
  `Animation`(Animation const &in_that)
  void `Assign`(Animation const &in_that)

    Share the underlying smart-pointer of the Animation source.

    Parameters: | in_that – The Animation source of the assignment.
    Returns: | A reference to this Animation.

  void `Delete`()

    Deletes this Animation.

  bool `Equals`(Animation const &in_that) const

    Check if the source Animation points to the same underlying impl as this Animation.

    Parameters: | in_that – The source Animation to compare to this Animation.
    Returns: | true if the objects reference the same impl, false otherwise.

  ChannelArray const &`GetChannels`() const

    Returns a list of Channels currently associated with this Animation.

    Returns: | a list of Channels currently associated with this Animation.
