Animation

class HPS::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.

UTF8 const &GetName() const

Returns the name given to this Animation when it was created.

Returns

The name of this Animation.

inline virtual HPS::Type ObjectType() const

This function returns the type the object, as declared (if the object is derived, this does not give the true type of the derived object).
