多个海龟，多个随机运动

Question

我有一个任务，必须在Python中用乌龟制作游戏。 我能够生成自己想要的网格，并且能够生成多个不同的海龟。我的 -在弄清楚如何让三只 不同 乌龟中的每只乌龟随机地在整个棋盘上移动时，我不知道从哪里开始，而是停留在网格线上。 -在两只乌龟撞到屏幕边缘后，“游戏”必须停止，我也不知道该怎么做。

这是我到目前为止所拥有的：

import turtle
import random

turtle.pensize(2)
turtle.penup()
turtle.goto(-160,-160)
turtle.pendown()
turtle.color("green")
turtle.speed(0)
for i in range(4):
    turtle.forward(320)
    turtle.left(90)

for y in range(-160,160,80):
    for x in range(-160,160,80):

        turtle.penup()
        turtle.goto(x,y)
        turtle.pendown()

        for k in range(4):
            turtle.forward(40)
            turtle.left(90)

        turtle.end_fill()       

for y in range(-120,160,80):
    for x in range(-120,160,80):

        turtle.penup()
        turtle.goto(x,y)
        turtle.pendown()
        for k in range(4):
            turtle.forward(40)
            turtle.left(90)


billy = turtle.Turtle()
billy.shape("turtle")
billy.color("red")
billy.penup()
billy.left(90)


rick = turtle.Turtle()
rick.shape("turtle")
rick.color("orange")
rick.penup()



mike = turtle.Turtle()
mike.shape("turtle")
mike.color("purple")
mike.penup()




turtle.done()

强有力的指导将非常有帮助。

您可以利用面向对象的优势。这是我的乌龟脚本版本：

import turtle
import random
# I added randint. 
from random import randint

# Let's define a class so we can create turtles
class MyTurtle():

  # Here's the constructor. Where we give some initial values.
  def __init__(self, name, color):
    self.name = name
    self.color = color
    self.turtle = turtle.Turtle()
    self.turtle.shape("turtle")
    self.turtle.color(self.color)
    self.turtle.speed(1)
    self.turtle.pd()

  # We need to know if this turtle is off the board.
  def off_board(self):
    x = self.turtle.xcor()
    y = self.turtle.ycor()
    return x < -160 or 160 < x or y < -160 or 160 < y

  # calling this will move the turtle in a random direction.
  def move(self):
    turn = randint(0,2)
    if turn == 1:
      self.turtle.lt(45)
    elif turn == 2:
      self.turtle.rt(45)
    self.turtle.forward(5)

# Put your code for drawing the grid 

# Let's create some turtles and start moving them.
turtles = []
turtles.append( MyTurtle('billy', 'red'))
turtles.append( MyTurtle('chris', 'blue'))
turtles.append( MyTurtle('lilly', 'pink'))
turtles.append( MyTurtle('kevin', 'green'))

ok = True
while ok:
  for t in turtles:
    t.move()
    if t.off_board():
      print ("Turtle %s wins!!!" % (t.name))
      ok = False

turtle.done()

加油！这个令人敬畏的乌龟剧本只是一个赞？
