How to Control Animation Speed in Turtle: Achieving Smooth and Deliberate Movement in Python

Optimizing Turtle Animation Speed in Python

While Turtle is a powerful tool for creating animations in Python, its inherent fast pace can be a drawback. To mitigate this, understanding the underlying principles of animation is essential.

In the provided Python code, the main issue lies within the usage of while True and sleep() within an event-driven environment like Turtle. Instead, employing a timer event within Turtle is recommended. Here's how to do it:

<code class="python">from turtle import Screen, Turtle

def rectangle(t):
    t.forward(50)
    t.left(90)
    t.backward(5)
    t.pendown()

    for _ in range(2):
        t.forward(10)
        t.right(90)
        t.forward(120)
        t.right(90)

    t.penup()

def windmill(t):
    for _ in range(4):
        t.penup()
        rectangle(t)
        t.goto(0, 0)

screen = Screen()
screen.tracer(0)

turtle = Turtle()
turtle.setheading(90)

def rotate():
    turtle.clear()
    windmill(turtle)
    screen.update()
    turtle.left(1)

    screen.ontimer(rotate, 40)  # adjust speed via second argument

rotate()

screen.mainloop()</code>

This revised code utilizes screen.ontimer(), which schedules the rotate() function to execute at a specific time interval (40 milliseconds in this case). By adjusting this interval, you can control the speed of the animation.
