Hi, I hope someone can help. I have a Python node in Xpresso. It has 2 input ports: Count (from a cloner) and Iteration (from an iterator). I am trying to enable and disable 100 Tracer objects based on the count in the cloner. I am using this code in the Python node but nothing is happening. (The list of tracers goes from cord Tracer_01 to cord Tracer_100)
import c4d from c4d import utils from c4d import documents mydoc = documents.GetActiveDocument() ctl = doc.SearchObject('cord Tracer') bc = c4d.BaseContainer() print ctl def main() : if Count <= Iteration: ctl[c4d.ID_BASEOBJECT_GENERATOR_FLAG == 1] else: ctl[c4d.ID_BASEOBJECT_GENERATOR_FLAG == 0] c4d.EventAdd() if __name__=='__main__': main()Any help would be greatly appreciated. Thanks.

From the C4D Help:
There are some limitations with regard to what Python does within a Python Node. Python Nodes are not allowed to directly access the CINEMA 4D project document or objects in the scene via Python. If, for example, you want to ascertain an object's current position within Python you can use XPresso Nodes to do this and pass this information via Ports to Python.
The Python Node is better suited for processing mathematical calculations and simple program structures, e.g., if-then-else. More complex Python applications should be executed via Python scripts in the Python Script Manager.

So I guess that's the problem. You are searching objects from within Python -

Here's a VERY simple XPresso setup that Enables or Disables Everything in the List.
Just select the Constant and enable - disable the "Value" button

Thank-you for your reply. I've decided to go with another, sleeker solution.
PS Cool talk you gave at Siggraph 2013.

Hi,
I'm glad this has already been solved.
I was working on this and got held up by Christmas vacation...
But as I came up with an example, I thought I post it nevertheless.
"Activate Simple Control" is a NULL object with three User Data values: Change Max (integer), Enable (Bool) and Link (a link field).
The Python code in "Python Activate Simple" is quite simple:
import c4d def main() : if not(doc) or not(Object) : return flagSelect = (Index < Max) or (Max < 0) # activate all on negative values Object[c4d.ID_BASEOBJECT_GENERATOR_FLAG] = flagSelect -

Thanks for taking the time to come up with this elegant solution! I really appreciate it.
