In a previous project called massive chasing game, you simulated a game where you created 100 turtles and each turtle chase the next one and the last turtle chase the first one.

In this project, instead of making the last turtle chase the first one, make it move on a circle forever. It will create an interesting animation shown above.

Source Code:

import turtle
import random
import colorsys

screen = turtle.Screen()
screen.tracer(0,0)
screen.setup(1000,1000)
screen.title('Chase the Cycler - PythonTurtle.Academy')
turtle.hideturtle()

n=200
chasers = []
for i in range(n):
    chasers.append(turtle.Turtle())

h = 0
for i in range(n):
    c = colorsys.hsv_to_rgb(h,1,0.8)
    h += 1/n
    chasers[i].color(c)
    chasers[i].up()
    chasers[i].goto(random.uniform(-500,500), random.uniform(-500,500))
chasers[n-1].goto(0,-300)
chasers[n-1].shape('circle')
chasers[n-1].shapesize(1)

def chase():
    for i in range(n-1):
        angle = chasers[i].towards(chasers[i+1])
        chasers[i].seth(angle)
    chasers[n-1].left(2)
    chasers[n-1].fd(10)
    for i in range(n-1):
        chasers[i].fd(10)
    screen.update()
    screen.ontimer(chase,1000//20)
    
chase()
