E-toys questions

I got nothing over at the Squeakland mailing list, so I thought I'd try
these questions here:

1. Can I find out when and where a user clicks in a world, and distinguish
between right and left clicks?

2. Why is it if I have a script that adjusts an object's position to
follow the mouse (by changing its X and/or Y by one to move it closer to
the current mouse position), I get a bobble (i.e., the graphic moves on,
then off, the mouse cursor repeatedly) if I set the script to fire an odd
number of times but not if I set it to even?

Thanks!

Jerome Peace answered this one: Apparently an object's X and Y aren't
necessarily integers.

Set the script to fire on mouseUp and set the players position to mouse
x and y.
There is no hooks for right click in e-toys I think.

Ah... OK. I guess we can use modalities to get around it.

And the script should be defined for the world player, because it's the
world that receive the mouseUp.
