CTrack backtracking

    So I have a track of an object using:

    object = doc.GetActiveObject()
      
    for track in object.GetCTracks() :
    	#do something
    

    What I would like to do is get the user data the track belongs to.

    for example Position Y the track is:

    <c4d.CTrack object called 'Position . Y/Track' with ID 5350 at 0x00000026E9C7D190>
    

    What I want to get:

    Cube[c4d.ID_BASEOBJECT_REL_POSITION,c4d.VECTOR_Y]
    

    How do I get from CTrack to c4d.VECTOR_Y?

    Overall what I am trying to do is create a port in an XPresso node for the attribute that is creating that curve.

    Let me know if I am not being clear enough.

    Thanks

    Hi Shawn,

    You can simply call CTrack.GetDescriptionID():

    import c4d
      
    def main() :
        for track in op.GetCTracks() :
            print track, track.GetDescriptionID()
            print op[track.GetDescriptionID()]
      
    if __name__=='__main__':
        main()

    Thanks for the reply Yannick,

    using GetDescriptionID() : I get (1001,19,23) which I am guessing is the ID for the attribute that is animated. 
    I am not familiar/still new to scripting, How do you use an ID once you have one?

    to create a node im using

    Node.AddPort(c4d.GV_PORT_OUTPUT,[c4d.ID_BASEOBJECT_POSITION])
    

    I am trying to get from the found track Position.Y to c4d.ID_BASEOBJECT_POSITION_Y .

    Using

    track.GetDescriptionID()[1].id
    

    I was able to get just the id of Position.Y "1001"

    I then found out that this can replace c4d.ID_BASEOBJECT_POSITION like so:

    Node.AddPort(c4d.GV_PORT_OUTPUT,[1001])
    

    Thanks for getting me on the right track!

    I lied,

    A more advanced setup was getting lost with just the ID you do need all 3 numbers. Honestly not sure how it was working with just a single ID.
