Hi Herbert,
Thanks for all trying and suggesting it's much appreciated - and
provides a lot of context for the classroom. I'm take a look at the
project file you sent It's great to know that so much constructive
feedback is available through the list.

Scott, thanks very much for both solutions (and that great explanation
about the fence).
The solution you've proposed here is pretty much what the student began
with. Except his scaling factor was slightly higher.
I'll see if I can post the project once it's finished.

"Bounce" is particularly unsuited to this example, because it reverses
the direction the paddle is "heading" and hence reverses the motion
brought about by "forward" commands. This makes it hard to retain an
intuitive relationship between the joystick and the motion of the
paddle.
FWIW h

Hi Herbert,
Thanks for trying the project. It's a first attempt (by a student) to
connect behavior of two objects in this case, a paddle and a joystick
mechanism. Like all first attempts, it will likely morph and correct and

Hi Scott,
Thanks for your detailed answer which among other things shows that the
beginners list is "A friendly place to get answers to even the most
basic questions about Squeak."
I'll take a look at the next Squeakland image (and the current one as
well) as you suggest. In the class I'm te
Hi, Mark,
What you're hearing is not a sound associated with the "bounce" but
rather a sound associated with an object hitting the "fence".
The "fence" is a feature that makes a "forward" command which would
take an object beyond the edge of its container result in the the
object's jiggli
Hi, polishookm,
I cannot reproduce the phenomenon you describe in any image I have
close to hand -- not in Squeak 3.9, not in Squeakland3.8-05, and not
in the OLPC etoys image. (Can anyone else?)
What version of Squeak are you using? If it's 3.10, I'll leave it for
other 3.10 users to
