Netlogo shown today:
Create 16 turtles Move forward 6 turtle steps
----------------- ---------------------------
cro 16 fd 6
Put your pen down Lift your pen (or turtle tail) up
----------------- ---------------------------------
pd pu
Turn right 90 degrees Clear all (erase everything)
--------------------- ----------------------------
rt 90 ca
Draw a square (if your Pen is Down - PD you will see square)
------------------------------------------------------------
repeat 4 [ fd 3 rt 90 ]
The above square has a side length of 3
Draw a cool pattern of 36 spiralling squares (if PD pen down)
-------------------------------------------------------------
repeat 36 [ rt 10 repeat 4 [ fd 3 rt 90 ] ]
What is 36 times 10? 360 degrees.
So you will have a complete
round the world circle of
squares.
Observer mode commands: ca, cro,
Turtles mode commands: fd, rt, pd, pu
Note: repeat is used in either mode, depending on what
you need to do.
repeat howManyTimes [ what you want to do ]
What would the following repeat create, if we assume the
pens of the turtles were down (PD or pd) so we could see
the trail left by the turtle tails (or pens, aka pens)?
repeat 8 [ fd 3 rt 45 ] <---- draws what????
repeat 4 [ fd 3 rt 90 ] <---- draws a square
