c4d.CTrack

This is the animation track base class. Contains CCurve that contain CKeys. A BaseList2D can host a CTrack object. This can be the position, rotation or custom value track. These tracks contain a CCurve which contains CKeys.

  • c4d.CTrack

Members

CTrack.__init__(bl, id)

Allocates a track object.

Parameters:

• bl (BaseList2D) – Object to allocate the track for.
• id (DescID) –

  Description ID to allocate the track for. For instance a position track will be allocated like this:

  tr=c4d.CTrack(op, c4d.DescID(c4d.DescLevel(c4d.ID_BASEOBJECT_POSITION, c4d.DTYPE_VECTOR, 0, ), c4d.DescLevel(c4d.VECTOR_X, c4d.DTYPE_REAL. 0)))

A track of type int will be allocated like this:

tr=c4d.CTrack(op, c4d.DescID(c4d.DescLevel(c4d.ID_BASEOBJECT_VISIBILITY_EDITOR, c4d.DTYPE_LONG, 0, )))

For a plugin and special tracks you pass the ID:

tr=c4d.CTrack(op,c4d.DescLevel(ID, ID, 0))

IDs for CINEMA’s special tracks are:

CTpla	PLA track.
CTsound	Sound track.
CTmorph	Morph track.
CTtime	Time track.
