I'll have to check this out.
sequences, where I can use a conditional to stop when the turtle would
go off the screen.
ah, good idea.
or
functions that return values, as opposed to "procedures" like:
def square(length):
forward(length)
right(90)
forward(length)
right(90)
forward(length)
right(90)
forward(length)
right(90)
Surely you mean
repeat(4)
forward(length)
right(90)
surely I don't mean. :)
that's not python. I'd do:
def square(length):
for i in range(4):
forward(length)
right(90)
but there isn't much difference with such a simple shape. obviously,
as one continued, the for-loop method would be clearer.
If-statements could possibly be used with some sort of random
behavior (if
rand()<0.5 ...).
Drunkard's Walk.
yes, that was the kind of thing I was thinking about.
thanks!
