etoy issues/making games and mazes

Hi,

In repsonse to recent email queries about making mazes/and creating 
scripts with feedback, I direct you to the "project swiki" that is 
part of the Squeakland site:

http://www.squeakland.org:8080/super/gallery

If you specifically check out the "Robot car in Maze" and "Sensor 
Car" projects you can see by using a conditional/test tile and the 
"color sees" tiles you can make a simple feedback script by just 
using "forward by" and "turn by" tiles.

What's great in this kind of project is the kids need to think about 
the direction of their object's heading and if the object needs to 
turn left or right to keep on the course and therefore they need to 
think about using positive or negative numbers.  This is very simple 
and does not even require thinking about x or y coordinates.  (We 
introduce that later.)  The kids LOVE making all kinds of variations 
of mazes and games.

By the way, *any* of you can and are welcome to publish/post your 
examples to this Project Gallery/Swiki.   To do this, hold down the 
"Publish" button on the gold navigator bar and select, "Publish to 
another server".  After you have named the project you wish to share, 
you'll get a directory in a blue window.  Selecting "Squeakland BSS" 
will publish your project to this page on the Squeakland site.   We'd 
love to see more examples here!

I hope these examples help!
have fun,
Kim
