pygame游戏之旅14：添加icon和bgm音效

添加icon需要用的函数是：

gameIcon = pygame.image.load("carIcon.png")
pygame.display.set_icon(gameIcon)

添加bgm和音效的函数是：

crash_sound = pygame.mixer.Sound("crashed.wav")
pygame.mixer.music.load("bgm.wav")

import pygame

import randompygame.init()crash_sound = pygame.mixer.Sound("crashed.wav")

bright_red = (255,0,0)
bright_green = (0,255,0)
