Thanks very much Jan. I thought of something like this but I was
hoping to slow the "trace" down somehow. Setting the points of a
polygon is instantaneous for each line segment . . . not the effect I
was hoping for. So far, I have made progress dragging the brush tool
as It gives me some choice of the line width. The only problem with
this is constructing an arrowhead at the end of the trace. At least,
this will be good brain exercise for me to work out the geometry!!
Cheers, Roger

I want to drag the polygon tool to trace over an

want the polygon tool instead of the pencil tool

to use "drag"
because I want to control the rate at which the
trace progresses via
"dragSpeed". However I can't seem to do anything
except trace a
straight line from the first point to the last point
of the invisible
polygon. Can anyone suggest how I might dynamically
trace over the
hidden polygon with a variable speed, variable line
width plus allow
for an arrowhead?
Thanks very much, Roger
Hi Roger,
One option is to trace the polygon by setting the
'points' property to the individual points of the
invisible polygon ; something like :
--
put the points of graphic "invisiblePolygon" into \
tInvisiblePoints
repeat for each line tPoint in tInvisiblePoints
put return & tPoint after tVisiblePoints
set the points of graphic "visiblePolygon" to \
tVisiblePoints
wait 1 second
end repeat

Hope this helped,
Jan Schenkel.
