How would I go about forcing my MoData Array to reflect the actual cloner count? As it stands, when I change the cloner count, the Array won't update until after I click in the Object Manager, at which time, the array length comes back correct.

I've tried adding c4d.EventAdd() and also resetting my array=[], but neither has any effect.

My test:

import c4d
from c4d.modules import mograph
#Welcome to the world of Python

def main() :
#ar = None

op = doc.SearchObject('Cloner') # Get cloner reference

md = mograph.GeGetMoData(op) # Get MoData on clones

ar = md.GetArray(c4d.MODATA_MATRIX) # Get array of clone matrices


print(str(op[c4d.MG_LINEAR_COUNT])) # Shows correct cloner count
print('array length: ' + str(len(ar))) # Shows incorrect array length

Thanks,

Jim

To me it sounds like a priority issue.
Either have your Expression tag object after the Cloner (lower in OM)
And/or set the priority of the expression tag to late Generators (480+ somewhere)

A quick test here and it worked in real time for me.

Oh man, I'm sorry I left this bit out. Thanks Lennart for the reply, but I'm not using a tag - my code is on the Python Generator, and I haven't been able to see a way to set any priority between it and the cloner.

I tried the function outlined here http://www.cineversity.com/wiki/Python%3A_Setting_Priorities/

But with no avail.

If you have any more advice that would be great.
FYI - I'm using the Python Generator in order to get the script to run upon User Data update, which I haven't been able to do using a tag. Essentially, I haven't learned how to listen to update events yet :)

Thanks,

Jim

Py Generator is generally meant for generating objects based on internal and/or external criteria.
If you're not making new objects I'd think an expression tag might be a better option, as you
can set the priority for it.
For Py Generator you would need to get and check various cache and dirty status of external objects.
A bit more complicated in my experience.

Thanks Lennart.
I am generating objects, so I'll take a look at that further.
