Hello,
I'm going to swallow my pride and ask the list... I just finished the drive-a-car (Proj 2) in "Powerful Ideas..." and at the end, after I've built the script to have the car turn in circles, I see the "Challenge" sidebar with the various geometric shapes. But I have no idea how to make a simple square. I don't believe I've learned anything up to this point that tells me how to "stop after traveling distance X" (so I can change my heading). The geometric shapes would seem to involve conditionals. Please enlighten this "professional" programmer :) Related, is there a searchable archive for the Squeakland list? (I found the raw archive)
Also, just some newbie feedback, the term "forward by N" seems a bit confusing. It really is "speed", isn't it? And if so, wouldn't every 1st-grader on understand the concept of speed?
thanks, Randy
