Problem:
Using the following code gives different behaviour on versions 2.6.4 and
3.0.1: nothing will be drawn under 3.0.1, but turtle.update() will force
the line to be drawn under 2.6.4. 2.6.4's behaviour is compatible with
the documentation: "turtle.update() - Perform a TurtleScreen update. To
be used when tracer is turned off."
import turtle
from time import sleep
turtle.tracer(100,0) # update screen after 100 drawings
turtle.fd(100)
turtle.update() # force update
sleep(100) # so you can see what's on the screen.
workaround:
use turtle.tracer(1) after drawing instead of turtle.update() |
