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：

1 import sys, pygame  2 from random import *  3 from pygame.locals import *  4 from pygame.font import *  5 class MyPlayer(pygame.sprite.Sprite):  6     def __init__(self, image_file, location, speed):  7         pygame.sprite.Sprite.__init__(self)  8         self.image = pygame.image.load(image_file)  9         self.rect = self.image.get_rect() 10         self.rect.left, self.rect.top = location 11         self.speed = speed 12         self.status = True 13     def move(self): 14         self.rect = self.rect.move(self.speed) 15         if self.rect.left < 0 or self.rect.right > width: 16             self.speed[0] = -self.speed[0] 17         if self.rect.top < 0:  18             self.speed[1] = -self.speed[1] 19         if self.rect.bottom > height: 20             #Game over 21             self.status = False 22 class Reflector(pygame.sprite.Sprite): 23     def __init__(self, image_file, location, speed): 24         pygame.sprite.Sprite.__init__(self) 25         self.image = pygame.image.load(image_file) 26         self.rect = self.image.get_rect() 27         self.rect.left, self.rect.top = location 28         self.speed = speed 29     def move(self): 30         self.rect = self.rect.move(self.speed) 31         if self.rect.left < 0 or self.rect.right > width: 32             self.speed[0] = -self.speed[0] 33         if self.rect.top < 0 or self.rect.bottom > height: 34             self.speed[1] = -self.speed[1] 35 def animate(players): 36     screen.fill([255,255,255]) 37     for player in players: 38         player.move() 39     for player in players:     40         players.remove(player) 41         if pygame.sprite.spritecollide(player,players,False): 42             player.speed[0] = -player.speed[0] 43             player.speed[1] = -player.speed[1] 44         players.add(player) 45         player.move() 46         screen.blit(player.image,player.rect) 47     pygame.display.flip() 48     pygame.time.delay(10) 49  50 pygame.init() 51 size = width,height = 640,480 52 screen = pygame.display.set_mode(size) 53 screen.fill([255,255,255]) 54 pygame.display.set_caption("MiaoWa Game") 55 def play(): 56     img_player = "C:\Users\dswu\Desktop\player.png" 57     players = pygame.sprite.Group() 58     for row in range(0,1): 59         for column in range(0,1): 60             playerLocation = [column*250+10,row*250+10] 61             playerSpeed = [choice([-2,2]), choice([-2,2])] 62             player = MyPlayer(img_player, playerLocation, playerSpeed) 63             players.add(player) 64     img_ref_path = "C:\Users\dswu\Desktop\Reflector.png" 65     ref_pos = [0,464] 66     ref_speed = [0,0] 67     reflector = Reflector(img_ref_path, ref_pos, ref_speed) 68     players.add(reflector) 69     running = True 70     while running: 71         key_pressed = pygame.key.get_pressed() 72         for event in pygame.event.get(): 73             if event.type == pygame.QUIT: 74                 game.quit() 75             if event.type == KEYDOWN: 76                 if event.key == K_LEFT:   77                     ref_speed[0] = -2 78                 elif event.key == K_RIGHT: 79                     ref_speed[0] = +2 80         animate(players) 81         if player.status == False: 82             running = False 83     final_text = "Game Over!" 84     ft_font = pygame.font.Font(None, 100) 85     ft_surf = ft_font.render(final_text, 1, (0,0,0)) 86     screen.blit(ft_surf, [screen.get_width()/2 - ft_surf.get_width()/2, 100]) 87     tip_text = "Type any key to continue" 88     tip_font = pygame.font.Font(None, 50) 89     tip_surf = tip_font.render(tip_text, 1, (0,0,0)) 90     screen.blit(tip_surf, [screen.get_width()/2 - tip_surf.get_width()/2, 200]) 91     pygame.display.flip() 92     keepOn = True 93     while keepOn: 94         key_pressed = pygame.key.get_pressed() 95         for event in pygame.event.get(): 96             if event.type == pygame.QUIT: 97                 pygame.quit() 98             if event.type == KEYDOWN: 99                 play()100 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：
