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？

多个海龟，多个随机运动
