python实现猫捉老鼠小游戏

首界面

开始游戏界面

然后键盘操作小老鼠上下左右移动，猫自己去追，当猫追上老鼠则游戏结束

这里用时3.2秒，最后将游戏时长与猫和老鼠都显示在主页面上

下面我把猫与老鼠的小图片也放上来供大家使用

以下是程序源代码

import turtle

import time

import random

def up():

jerry.setheading(90)

jerry.forward(20)

def down():

jerry.setheading(270)

jerry.forward(20)

def left():

jerry.setheading(180)

jerry.forward(20)

def right():

jerry.setheading(0)

jerry.forward(20)

playground=turtle.Screen()

playground.register_shape('tom.gif')

playground.register_shape('jerry.gif')

playground.onkey(up,'Up')

playground.onkey(down,'Down')

playground.onkey(left,'Left')

playground.onkey(right,'Right')

#监听

playground.listen()

writer=turtle.Turtle()

writer.color('brown')

writer.hideturtle()

writer.penup()

writer.home()

writer.write("Tom & JERRY",align='center',font=("Comic sans MS",50,"bold"))

writer.goto(0,-50)

writer.write("READY?3,2,1,GO",align='center',font=("Comic sans MS",20,"bold"))

time.sleep(3)

writer.clear()

tom=turtle.Turtle()

tom.shape('tom.gif')

tom.penup()

tom.goto(random.randint(-200,200),random.randint(-200,200))

tom.pendown()

tom.pensize(3)

tom.color('blue')

jerry=turtle.Turtle()

jerry.shape('jerry.gif')

jerry.speed(0)

jerry.penup()

jerry.goto(random.randint(-200,200),random.randint(-200,200))

jerry.color('brown')

start=time.time()

while True:

tom.setheading(tom.towards(jerry))

tom.forward(5)

if tom.distance(jerry)<10:

end=time.time()

playground.clear()

jerry.goto(0,0)

jerry.write("GAME OVER",align='center',font=("Comic sans MS",50,"bold"))

jerry.goto(0,-50)

jerry.write("YOU SURVIVED {:.1f} SECONDS".format(end-start),align='center',font=("Comic sans MS",20,"bold"))

tom.pu()

tom.goto(-50,-70)

tom.stamp()

jerry.pu()

jerry.goto(50,-70)

jerry.stamp()

break
