Just to bump this

From what I can see there no connection between a PY Effector and the Cloner(s) that is/are using it?

Can we get an answer on this one please either way - as the OP was early December.

OK Apart from going through the cloners - checking their effector list to see if it is using the Python effector
is there any other way of getting the Cloner object the effector is attached to?

GetGenerator() is missing in the Python API and will be implemented in the future.

Meanwhile, the best workaround is to add a Link user data to the Python Effector and connect the Cloner.
Then in the Python effector code you could call:

cloner = op[c4d.ID_USERDATA, 1]
print cloner

Thanks for the feedback Yannick

but I think this will be a problem if you use the effector in more than one cloner
ie an unspecified number of cloers

I'm thinking
search OM for cloners
check effector list
am I in there?

You can create as many Link user data as cloners.

Yes, meanwhile this solution may be the best for complex situations.

Sebastian just told me that in the Python effector scope there's a variable called "gen"... So we can access the cloner object with this variable.

A quick example would save a lot of guesswork pls

Basically, 'gen' is the name of a variable (referencing the cloner or generator object) added to the execution of main() function in a Python effector, just as the same as 'doc' (document where the effector resides) and 'op' (effector) variables:

import c4d
from c4d.modules import mograph as mo
#Welcome to the world of Python
  
def main() :
    md = mo.GeGetMoData(op)
    if md==None: return 1.0
    
    # Print variables added to the scope of main()
    print op
    print gen
    print doc
    
    index = md.GetCurrentIndex()
    mode = md.GetBlendID()

Ah - I see

got it

place in a Python Effector and run

bingo, that works.

try again, deepshade.
( I think you're still working on a python version of d_PolySize.)
I just tried :

cloneobj = gen[c4d.MG_OBJECT_LINK]
print cloneobj

and it does return the Object the Cloner's cloning onto correctly,
although it gets funky when there's multiple cloners referencingthe same Effector

thanks, yannick

multiple cloner issue here too

douwe - re: d_PolySize - still getting stuck on the coffee poly manipulation
can you annotate to make conversion (a little) easier

Why
When the python effector is set to Full Control
does GEN returns the Cloner

and
when the python effector is set to Parameter Control
does GEN returns the Cloner Object Link
???

or to put it another way
is the variable GEN in parameter mode
returned incorrectly ie a bug

If there is a difference - can someone explain why pls - as there is no documentation of the modes working differently other than (from what I can see) the parameter version appears to be hooked to refresh once for every clone count
