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
总结
