一.内容
小球的碰撞游戏
游戏规则：
1.游戏初始化的时候，有5个不同颜色的小球进行碰撞
2.玩家可以通过在窗口中单击鼠标左键进行增加小球个数
3.玩家可以通过在窗口中单击鼠标右键进行删减小球个数
4.玩家可以通过键盘的方向键：上，右键进行对小球加速
5.玩家可以通过键盘的方向键：下，左键进行对小球减速
6.玩家可以按键盘：f键实现全屏显示
7.玩家可以按键盘：Esc键实现退出全屏操作
8.窗口左下角显示小球个数，右下角显示作者邮箱

  *感谢pong的代码我写的大炮游戏太挫运行不出来*

二.赏析

if not pygame.font: print('Warning, fonts disabled')
if not pygame.mixer: print('Warning, sound disabled')

让程序更稳定，若音频与图片加载不成功直接报错

SCREEN_WIDTH = 600
SCREEN_HEIGHT = 500
SPEED = 1
VOLUME = 5
SCREEN_DEFAULT_SIZE = (SCREEN_WIDTH, SCREEN_HEIGHT + 20)
SCREEN_DEFAULT_COLOR = (255, 255 ,255)
READY = 0

设定初始条件

screen = pygame.display.set_mode(SCREEN_DEFAULT_SIZE, 0, 32)
screen.fill(SCREEN_DEFAULT_COLOR)
bg = pygame.image.load('data\\image\\bg.jpg').convert()
font = pygame.font.Font('data\\font\\TORK____.ttf', 14)
new_sound = pygame.mixer.Sound('data\\sound\\new.wav')
bg_sound = pygame.mixer.Sound('data\\sound\\bg.ogg')
bg_sound.set_volume(0.1 * VOLUME)
bg_sound.play(-1)
new_sound.set_volume(0.1 * VOLUME)
