Create more than two turtles and moving them

问题

How to make few turtles in a screen and make them move one at once?

回答1:

You can use turtle.Turtle() to create many turtles and then you can use it one by one to make small move. Turtles will move almost at the same time.

import turtle

t1 = turtle.Turtle()
t2 = turtle.Turtle()

for x in range(36):
    # first turtle makes small move
    t1.left(10)  
    t1.forward(10)
    # second turtle makes small move
    t2.right(10)
    t2.forward(10)

turtle.done()

If you want to move all the time (and do other things at the same time)
then you can use ontimer() to make small moves.

import turtle

def move_t1():
    # first turtle makes small move
    t1.left(10)  
    t1.forward(10)

    # repeat after 100ms
    turtle.ontimer(move_t1, 100)

def move_t2():
    # second turtle makes small move
    t2.right(10)  
    t2.forward(10)

    # repeat after 100ms
    turtle.ontimer(move_t2, 100)

t1 = turtle.Turtle()
t2 = turtle.Turtle()

move_t1() # first turtle makes first move
move_t2() # second turtle makes first move

turtle.done()
