Re: Second Turtle following First Turtle, but from a Distance

 Dear Alain,

 Many thanks.  This was the kind of procedure I envisioned, but  
didn't know how to put in the correct syntax.  We tried it today, and  
did, in fact, play with the values, until we arrived at the  
following, below.  "To dribble" was in the onclick box of the  
offensive basketball player/turtle dribbling the ball, and your  
"getcloser" procedure was in the onclick box of the defensive  
basketball player/turtle.
 We added a colored box border around the edges of the screen, so  
the players wouldn't disappear above and reappear below.
 Would I assume that if we didn't want to have the players defying  
the "law of gravity," could we also place parameters on the xcor and  
the ycor, so the players couldn't go above the bleachers?  Or we  
could have them playing on a space station in zero G.
 to dribble

         t1, forever [fd random 50 wait 2 rt random 30]
         forever [pt, fd 2 rt 1]
end

to getcloser
	towards "t1
	if (distance "t1) > 100 [fd 10 wait 1]
end

to bounce
         rt 180
end

to start
         t1, setpos [270 0]
         t2, setpos [150 0]
         everyone [clickon]
end

Anyway, thanks for the suggestion.  It was right on target.
