Use these commands directly in the bottom text area to move the Turtle. Or combine them into new "words" (sometimes called procedures or functions) in the top box, and then use the new "words" in the bottom box.
Note: Omit < >, these brackets are used to indicate where you should enter desired values
forward / fd <distance>
back / bk <distance>
right / rt <angle>
left / lt <angle>
repeat [commands to repeat]
penup / pu
pendown / pd
hideturtle / ht
showturtle / st
spin <speed>
Starts the turtle spinning. Anything drawn later with also be spinning.
grow <length> <time>
Draws a line that grows and shrink. The length input sets the maximum length of the line. The time inputs says how long the grow/shrink cycle is.
setphase <angle>
sets the phase angle for subsequent grow commands
lineto <x> <y>
moves the turtle to <x>, <y> drawing a line if the pen is down. (setxy never draws a line>
storept <n>
saves the current turtle position. (even as its moving)
<n> should be a number
gotopt <n>
moves the turtle back to a saved point
joinpts <n1> <n2>
draws a line between two stored points.
Use this pattern in the top text area to create new "words" that you can then use in the bottom text area to move the Turtle
"Words" follow this general pattern:
to <word>
<commands go here, use as many as you like>
end
save <filename>
