-- 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
