You can set the clock variable the same as the frame number. For example:
initial_clock = 0;
final_clock = 10;
initial_frame_number = 0;
final_frame_number = 10;
This way the clock variable will have always the frame number so you can set
it on the sphere_sweep.
I dont remember if those are the right syntax, but you can read the docs
instead.
See ya.
