This is a hack that lets newbies do some collision logic simply.  The first parameter is a color which defines a sensitive part of me.  Think of a bug with a red nose.  The second parameter is a color that we're looking for in the world.  Think of a yellow flower.  Now you can write a very simple script that will cause a wandering bug to stick to a yellow flower if it finds one.  You can do maze following, autopilot and lots of cool things with this.

The Quote is from the Wizard of OZ.  I wouldn't try to duplicate it - it is cute but not useful.  The path used is the one defined by the 'draw new path' option in the menu of the red halo button.

Hope this helps.
