Python中写一个乒乓球类的游戏

最近开始学Python，感觉挺好玩的，既有脚本语言的灵活性，又有丰富的类库与面向对象的特点，开发起来很方便。

游戏的规则和乒乓球一样，如果妙蛙种子掉地上了就算输，你可以用蓝色的跷跷板弹它，使他不落到地面上。

Game Over后可按任意键继续游戏或选择退出。

代码如下：

 import sys, pygame
 from random import *
 from pygame.locals import *
 from pygame.font import *
 class MyPlayer(pygame.sprite.Sprite):
     def __init__(self, image_file, location, speed):
         pygame.sprite.Sprite.__init__(self)
         self.image = pygame.image.load(image_file)
         self.rect = self.image.get_rect()
         self.rect.left, self.rect.top = location
         self.speed = speed
         self.status = True
     def move(self):
         self.rect = self.rect.move(self.speed)
         if self.rect.left <  or self.rect.right > width:
             self.speed[] = -self.speed[]
         if self.rect.top < :
             self.speed[] = -self.speed[]
         if self.rect.bottom > height:
             #Game over
             self.status = False
 class Reflector(pygame.sprite.Sprite):
     def __init__(self, image_file, location, speed):
         pygame.sprite.Sprite.__init__(self)
         self.image = pygame.image.load(image_file)
         self.rect = self.image.get_rect()
         self.rect.left, self.rect.top = location
         self.speed = speed
     def move(self):
         self.rect = self.rect.move(self.speed)
         if self.rect.left <  or self.rect.right > width:
             self.speed[] = -self.speed[]
         if self.rect.top <  or self.rect.bottom > height:
             self.speed[] = -self.speed[]
 def animate(players):
     screen.fill([,,])
     for player in players:
         player.move()
     for player in players:
         players.remove(player)
         if pygame.sprite.spritecollide(player,players,False):
             player.speed[] = -player.speed[]
             player.speed[] = -player.speed[]
         players.add(player)
         player.move()
         screen.blit(player.image,player.rect)
     pygame.display.flip()
     pygame.time.delay()

 pygame.init()
 size = width,height = ,
 screen = pygame.display.set_mode(size)
 screen.fill([,,])
 pygame.display.set_caption("MiaoWa Game")
 def play():
     img_player = "C:\Users\dswu\Desktop\player.png"
     players = pygame.sprite.Group()
     for row in range(,):
         for column in range(,):
             playerLocation = [column*+,row*+]
             playerSpeed = [choice([-,]), choice([-,])]
             player = MyPlayer(img_player, playerLocation, playerSpeed)
             players.add(player)
     img_ref_path = "C:\Users\dswu\Desktop\Reflector.png"
     ref_pos = [,]
     ref_speed = [,]
     reflector = Reflector(img_ref_path, ref_pos, ref_speed)
     players.add(reflector)
     running = True
     while running:
         key_pressed = pygame.key.get_pressed()
         for event in pygame.event.get():
             if event.type == pygame.QUIT:
                 game.quit()
             if event.type == KEYDOWN:
                 if event.key == K_LEFT:
                     ref_speed[] = -
                 elif event.key == K_RIGHT:
                     ref_speed[] = +
         animate(players)
         if player.status == False:
             running = False
     final_text = "Game Over!"
     ft_font = pygame.font.Font(None, )
     ft_surf = ft_font.render(final_text, , (,,))
     screen.blit(ft_surf, [screen.get_width()/ - ft_surf.get_width()/, ])
     tip_text = "Type any key to continue"
     tip_font = pygame.font.Font(None, )
     tip_surf = tip_font.render(tip_text, , (,,))
     screen.blit(tip_surf, [screen.get_width()/ - tip_surf.get_width()/, ])
     pygame.display.flip()
     keepOn = True
     while keepOn:
         key_pressed = pygame.key.get_pressed()
         for event in pygame.event.get():
             if event.type == pygame.QUIT:
                 pygame.quit()
             if event.type == KEYDOWN:
                 play()
 play()

主要是通过pygame.sprite.Sprite类实现碰撞的监控，通过事件的捕捉及判断实现这种弹力球类的游戏，其中涉及到文字在界面上的显示，游戏中的循环控制，以及重新开始游戏等。

把上面这段代码贴到你的IDLE中，找到下面这两行替换成你机器中的图片路径，按F5就可以运行了。

img_player = "C:\Users\dswu\Desktop\player.png"
img_ref_path = "C:\Users\dswu\Desktop\Reflector.png"

由于比较简单，看看代码运行一下应该就差不多明白了，如果有不明白的地方请给我留言，方便一起学习与进步。

平时都在线，欢迎交流。

Version2，增加score计分功能，结构有改动：
