Any ideas on this reactor?

I have two items. A circle shaped block and a line. How do I make a reactor
that will update the point of one end of the line when I move the other end.

The problem I am having is that the reactor does not work when I edit the
item that is to react. Is my logic just screwed up or is there some trick I
can use to get around this? I can code it if someone knows how to point me
in the right direction.

Thanks for any advice

Hi kemp,
you should show some code

I tried the same thing. I think the problem is that you can't change the
object that caused the reaction through lisp, since that would re-fire the
reactor again and you would eventually overflow the stack. I read somewhere
that you might be able to do something by using vla-properties, but I gave
up at that point.
