I am trying to plot a calculated point ( the midpoint between points) every let’s say 1 second after pushing an action button

- User starts by picking an ordered pair. lets call it point A
- CL chooses a random point from a set of three fixed points and then
- midpoint is plotted call it (B) , after 1 second the midpoint of last point plotted B and one of the same fixed points is plotted.
- continue for as long as you want

Any help?

Thanks, Gregg Klein
