pygame游戏之旅 添加icon和bgm音效的方法

本文为大家分享了pygame游戏之旅的第14篇，供大家参考，具体内容如下

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")

源码：

import pygame
import time
import random

pygame.init()

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