Hmmm.

Your questions are kind of general..

There are lots of different ways to get things to move.

In the Hanoi demo, clicking the mouse button over a top ring and
keeping it pressed while moving the mouse.. will move the ring.

Most things in VPython have an attribute called "pos", representing
its 3d coorinates

Experiment from the IDLE prompt.

IDLE 1.0.3

from visual import * Visual 2004-07-22 s=sphere(color=color.blue, pos=(2,2,2))
You will see a window with a blue sphere.

Then: s.pos=(0,2,2)

The sphere's position in the window moved.

Cool.

Moving things in Vpython is usually a matter of having a porgram that
changes things "pos", in reaction to something - a mouse click, the
passage of seconds, etc.

Help?

Noting the question, the first two responses you got, and
your subsequent question, I suggest you would benefit

Note to the original poster: before you think Peter is being arrogant or a
smartass, please realize that's probably the single most useful answer you'll
ever get to a question on the internet. And yes, I've actually read that
document once or twice in the past, carefully.

So don't react badly, take his advice, read that document, make sure you
understand it, and try again. I'm sure you'll find the result worth every
minute of effort spent. Otherwise you'll continue to get correct answers like
you have so far to your questions. Correct, but perfectly useless (because the
questions were worded _begging_ for useless answers).

best,

Oops. I forgot. I really did.

What IDLE prompt?

The VPython Windows distribution has the gaul to overwrite the
conifig-main.def file in the idlelib directory changing the default
behavior of IDLE on start-up to be a text editor, rather than an
interactive prompt.

This despite the fact that:

a) The person responsible for configuring the distribution knows that
the developers of IDLE =- specifically one GvR - made a clear
statement as to wanting the prompt as the default start-up.

b) The new IDLE has specifcally added the ability for user defined
configuration of options without touching anything in the idlelib
directory.

c) This kind of overwrite of lib files, it seems to me, is bad form in
any case.

The fact that I think that the decision is also ridiculous, on its
merits, being totally besides the point.

The OP, depending on his profile, may in actual fact have no idea what
I am talking about by referring to the IDLE interactive prompt -
having downloaded VPython.

I had made an issue of this - again - recently on edu-sig. To a
resounding thud of reaction. But this little exhange proves at least,
to myself, that I am attacking something real. Not just looking to
pick a fight.
