Wiggles with LYNX

1. Click on the EDIT button to open the LYNX Editor.

You will see:

• the graphics area on the right

• the Procedures Pane on the left

The Wiggle1 button carries out the instructions that are in the Wiggle1 procedure. 

Explaining the code!

to WIGGLE1  (tells the turtle you are teaching it a new command (procedure) called WIGGLE1) 

pd (tells the turtle to put its pen down so it will draw) 

forward 80  (tells the turtle to move forward 80 steps (pixels))

right 60 (tells the turtle to turn right 90 degrees)

back 80 (tells the turtle to move forward 80 steps (pixels))

left 120 (tells the turtle to turn left 120 degrees)

pu  (tells the turtle to lift its pen up) 

end (tells the turtle you are finished teaching it this procedure)

; click the wiggle1 button 6 times. It makes a star (any line that starts with a semicolon ; is a comment and doesn't run any code. In this case, they are here to give you a challenge!) 

; change numbers above to make a smaller star ;-) (Another challenge!)
