Hi, Ilia:
I prefer to control an object in real-time, could you give some examples for doing it?
best regards

Hi, Ilia:
Thanks a lot for your assistance. I have already thought if using key frames can do it? However my task is to control a model object in real-time interactively. The key frames must be preset in advance.

I try to move the eyeball step by step, but it only moves one step, suddenly moves to the last position. The middle course doesn't show up, and the 'for' loop seems not to be effective and becomes a big step seemingly.

import c4d
from c4d import gui
import time
# Welcome to the world of Python



# Main function
def main():
    tag = doc.GetActiveTag()


    tag.ExitEdit(doc,True)
    rightleft = tag.GetMorphID(2)
    updown = tag.GetMorphID(1)
    for i in range(15):
        tag[rightleft]+=0.05
        tag[updown]+=0.06
        print(tag[rightleft])
        time.sleep(0.3)
        tag.UpdateMorphs()

    c4d.EventAdd()




# Execute main()
if __name__=='__main__':
    main()

EDIT: (Ilia) forked from here and formatted the code

thanks a lot, your post is working for me.

In addition, I am new for c4d and here. Hopefully, more responses and assistance.

I already created an eyeball in c4d, and make a posemorph for it. I have used GetMorph() to get the objects of tag. In my design, it can move left right, and up and down, in c4d, it can do. Now I want to use python to work it, but I don't know how to use method or set value make it rotate in c4d, I have add strength sliders for left-right and up-down. Which methods can I use to rotate the eyeball in python?
