Effector created with python doesn't work anymore after closing the file

oli_d

Hi,
When I run the following code that creates an effector, everything works perfectly. If I save the file, close it and open it again, the effector does nothing and it is impossible to make it work.

import c4d


def main():
    res = c4d.BaseObject(c4d.Onull)
    cloner = c4d.BaseObject(1018544)
    cloner.InsertUnder(res)

    rdm_effector = c4d.BaseObject(1018643)   
    rdm_effector.InsertUnder(res)
    
    inex_data = cloner[c4d.ID_MG_MOTIONGENERATOR_EFFECTORLIST]
    inex_data.InsertObject(rdm_effector,1)
    cloner[c4d.ID_MG_MOTIONGENERATOR_EFFECTORLIST] = inex_data

    if op:
        op.InsertUnder(cloner)

    doc.InsertObject(res)
    c4d.EventAdd()

if __name__=='__main__':
    main()

With CallCommand it works, but it's not very practical.

import c4d
from c4d import gui

def main():

    res = c4d.BaseObject(c4d.Onull)
    cloner = c4d.BaseObject(1018544)
    cloner.InsertUnder(res)

    if op:
        op.InsertUnder(cloner)

    doc.InsertObject(res)

    doc.SetActiveObject(cloner)

    c4d.CallCommand(1018643) # Effecteur Randomisation
    c4d.EventAdd()
    return

if __name__=='__main__':
    main()

Bug or incompetence?

(C4D r21.207 and s22.016 on macos 10.13.6)

Hi @oli_d you should call rdm_effector.Message(c4d.MSG_MENUPREPARE, doc) after its insertion in the doc like

import c4d


def main():
    res = c4d.BaseObject(c4d.Onull)
    cloner = c4d.BaseObject(1018544)
    cloner.InsertUnder(res)

    rdm_effector = c4d.BaseObject(1018643)   
    rdm_effector.InsertUnder(res)
    
    inex_data = cloner[c4d.ID_MG_MOTIONGENERATOR_EFFECTORLIST]
    inex_data.InsertObject(rdm_effector,1)
    cloner[c4d.ID_MG_MOTIONGENERATOR_EFFECTORLIST] = inex_data

    if op:
        op.InsertUnder(cloner)

    doc.InsertObject(res)
    rdm_effector.Message(c4d.MSG_MENUPREPARE, doc)
    c4d.EventAdd()

if __name__=='__main__':
    main()

Cheers,
Maxime.
