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:

  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

 55 def play():

 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()

 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。
