In an aninmation, you don't need a loop to do the translation. What you need is to use
the clock to 
move the camera or the object that will do the zig-zag. The rest is just dessiding on
the timing you 
want.
You usualy use a while loop when you want to put several similar objects in your
scene. There are 
many other uses, but that's one of the most obvious.
