hello,
this is because the modata are store in a tag that is not created yet.
a "workaround" is to create it in a "temporary document" and ExecutePasses() on it.
So the cloner will create the hidden tag and you will be able to retrieve the MoData
import c4d
#Welcome to the world of Python
def CreateClonerAndFun(base, rad):
"""
Creates the cloner, clone the base.
Creates the effector
return the parent and the cloner.
"""
parent = c4d.BaseObject(c4d.Onull)
base = base.GetClone()
base.InsertUnderLast(parent)
cloner = c4d.BaseObject(1018544)
cloner.InsertUnder(parent)
p = c4d.BaseObject(c4d.Onull)
p[c4d.NULLOBJECT_DISPLAY] = 2
p[c4d.NULLOBJECT_RADIUS] = rad
p.InsertUnder(cloner)
pushEffector = c4d.BaseObject(440000219)
pushEffector[c4d.MGPUSHAPARTEFFECTOR_MODE] = 0
pushEffector[c4d.MGPUSHAPARTEFFECTOR_RADIUS] = rad
pushEffector.InsertUnderLast(parent)
ie = c4d.InExcludeData()
ie.InsertObject(pushEffector,15)
cloner[c4d.ID_MG_MOTIONGENERATOR_MODE] = 0
cloner[c4d.ID_MG_MOTIONGENERATOR_EFFECTORLIST] = ie
cloner[c4d.MG_OBJECT_LINK] = base
cloner[c4d.MG_POLY_MODE_] = 0
return parent, cloner
def main():
# Checks if we got a child
child = op.GetDown()
if child is None:
raise ValueError("no child on this generator")
# using a function to avoid double code
parent, cloner = CreateClonerAndFun(child, 10)
# Creates a new Document
newDoc = c4d.documents.BaseDocument()
# Inserts the object in the new document
newDoc.InsertObject(parent)
# ExecutePasses on the document
if not newDoc.ExecutePasses(None,True,True,True, c4d.BUILDFLAGS_NONE):
raise ValueError("erro while updating the document")
# Retrieves the modata from the object
md = c4d.modules.mograph.GeGetMoData(cloner)
print md
# Re-create the cloner but this time to return the parent.
return CreateClonerAndFun(child, 10)[0]
