I have a really simple task to draw an X in python using Turtles, but i cannot seem to understand how the setposition() method works.
my code currently draws the first line correct, but then the second line skews up too much no matter what i try.
t.right(45)
t.pendown()
t.setposition(50,-50)
t.penup()
t.left(90)
t.setposition(0,-50)
t.pendown()
t.setposition(50,50)
Your first line starts at (0,0)
and got to (50, -50)
, thus goes 50 units in X and Y direction. But you second ist going from (0,-50)
to (50,50)
, thus goes 50 units in X direction and 100 units in Y direction. Additionally your right and left have no effect.
One possible solution would be:
t.setposition(-50,50)
t.pendown()
t.setposition(50,-50)
t.penup()
t.setposition(-50,-50)
t.pendown()
t.setposition(50,50)
Another approach you can take is to avoid setposition()
altogether and think like a turtle. That is, crawl forward, backward and turn rather than teleport:
import turtle as t
t.right(45)
t.forward(70)
t.backward(140)
t.forward(70)
t.left(90)
t.forward(70)
t.backward(140)
t.hideturtle()
t.done()
