打鼹鼠Python

Question

我试图用Python为一个whack-a-mole程序创建一个面向对象的程序。在

我想保持这个简单，这里只有一个锤子和一个鼹鼠，当锤子龟和鼹鼠龟接触时。在

我已经创建了4个类，一个是游戏的超类，一个是从乌龟继承的精灵，一个是从精灵继承的锤子和鼹鼠。在

我要问的是如何实例化mole和hammer-tures，我已经使用了继承，但是希望最小化我使用的方法的数量 我使用的代码是

import random
import turtle
wn=turtle.Screen()
wn.addshape("moleSmall.gif")
wn.addshape("Mole.gif")
wn.addshape("Hammer.gif")
turtle.setup(800, 600)

class Game():
    def __init__(self):
        self.score=0
        self.pointsDisplay=Points()

    def update_score(self,x,y):
        self.score = self.score + 2
        print("Score:", self.score)
        self.callDisplayScore()        
    def decrease_score(self,x,y):
        self.score = self.score -1
        print("Score: ", self.score)
        self.callDisplayScore()
    def callDisplayScore(self): 
        score = self.score
class Sprite(turtle.Turtle):
    def __init__(self):
        turtle.Turtle.__init__(self)
        self.x=0
        self.y=0
        crash =False
        self.crash=crash
    def randomMove(self):        
        leftbound = -self.wn.window_width()/2

        bottombound = -self.wn.window_height()/2
        rand_x = random.randint(leftbound , rightbound)
        rand_y = random.randint(bottombound, topbound) 
        self.mole.setpos(rand_x,rand_y)
    def collisionCheck(self,turtle1, turtle2):
        self.crash = False
        turtle1X = turtle1.xcor()
        turtle1Y = turtle1.ycor()
        turtle2X = turtle2.xcor()
        turtle2Y = turtle2.ycor()
        turtle1Pos = (int(turtle1X), int(turtle1Y))
        turtle2Pos = (int(turtle2X), int(turtle2Y))

            turtle1Y > turtle2Y - 50 and  turtle1X < turtle2X - 50 and\
            turtle1Y > turtle2Y + 50:
            self.crash = True
        return self.crash
