Insert User Data Track in Python
-
Hello,
I would like to add track (timeline) for each user data I have set on a object .
Here is the code I tried, but I don't know why it's not workingHere is the code I wrote :
import c4d from c4d import gui #Création d'une piste pour chaque donnée utilisateur def AddAnimationTrack(op): LED = c4d.CTrack(op,c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA,1,c4d.DTYPE_GROUP),c4d.DescLevel(c4d.ID_USERDATA,2,c4d.DTYPE_GROUP),c4d.DescLevel(c4d.ID_USERDATA,3,c4d.DTYPE_REAL))) op.InsertTrackSorted(LED) return True # Main function def main(): AddAnimationTrack(op) # Execute main() if __name__=='__main__': main()
I work on R21.
You can see the scene here : ADD_TRACK - 1.c4dThank you for helping

Your DescID looks weird. Try something like:
c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER), c4d.DescLevel(userdata_entry,c4d.DTYPE_LONG))
with userdata_entry being the actual ID of the user data.
(Disclaimer: I didn't sit down and try this, but the code is from a script dealing with animations (FindTrack), so I'm confident it should work.)

@cairyn said in Insert User Data Track in Python:
c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER),
c4d.DescLevel(userdata_entry,c4d.DTYPE_LONG))Hello ! Thank you for replying !
I've put your code but get a error :
"Traceback (most recent call last):
File "scriptmanager", line 19, in <module>
File "scriptmanager", line 15, in main
File "scriptmanager", line 9, in AddAnimationTrack
NameError: global name 'userdata_entry' is not defined"Maybe I didn't get what I should do with "userdata_entry"

This is what the code looks like now :
import c4d from c4d import gui #Création d'une piste pour chaque donnée utilisateur def AddAnimationTrack(op): LED = c4d.CTrack(c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER), c4d.DescLevel(c4d.ID_USERDATA,3,c4d.DTYPE_LONG))) op.InsertTrackSorted(LED) return True # Main function def main(): AddAnimationTrack(op) # Execute main() if __name__=='__main__': main()

@hugo-battistella userdata_entry is a variable I was using in the script. It stands for the ID of the user data entry as shown in the user data dialog on the right side, for example 1 here:
If you have that user data in your object, you can query op (the selected object) in the console like this:
op[c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA, c4d.DTYPE_SUBCONTAINER),c4d.DescLevel(1,c4d.DTYPE_REAL))]
This is also true if the data entry is part of a group.

@hugo-battistella The DescID represents a hierarchical structure, so it makes no sense to put ID_USERDATA into the second DescLevel. The first DescLevel identifies the UserData structure within the object. The second DescLevel identifies the entry in that UserData by its ID (for which you'd have to define a proper constant yourself).
Also, the constructor for a track requires the object as first parameter. This code works for me:
import c4d from c4d import gui def AddAnimationTrack(op): LED = c4d.CTrack(op, c4d.DescID(c4d.DescLevel(c4d.ID_USERDATA,c4d.DTYPE_SUBCONTAINER), c4d.DescLevel(1,c4d.DTYPE_REAL))) op.InsertTrackSorted(LED) return True def main(): AddAnimationTrack(op) c4d.EventAdd() if __name__=='__main__': main()
(provided I have a user data with ID 1 as shown in the screenshot from my last post, and this object is selected.)

Hello @Cairyn,
thank you a lot for this answer. I try this quikly but now I have a better understanding of the Desclevels concept ! -
That works find ! Thank you so much
