python实现猫捉老鼠小游戏

首界面

image.png 开始游戏界面

image.png 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

image.png 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

time.sleep(3)

jerry.shape('jerry.gif')
jerry.speed(0)
jerry.penup()
jerry.goto(random.randint(-200,200),random.randint(-200,200))

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
