cascade animation does not work in my scene:

I try to cascade animation. But it is not working, any idea why?
See my scene below. Poth cones start the animation at the same time.
Also, at the end I want to make a animation that has a queue of more
than 1000 such animations that all need to be played one ofter the
other.
How can I avoid to make 1000 timers and 1000 interplators

By using a PROTO.
The more interesting question is, how to avoid 1000 ROUTES.
Maybe 1000 ROUTES can be avoided by directOutput and setting of
TimeSensor.startTime and TimeSensor.stopTime to the values
"currentTime + some offset"

could you maybe give me a little example how to cascade maybe three
animations one after the other. Maybe also with the use of proto ?

The following is possibly not exactly, cause each node start will relativly
to "the loading time of the script" script3, but i think, you get the idea.
