pygame介绍
Python Pygame 是一款专门为开发和设计 2D 电子游戏而生的软件包,它支 Windows、Linux、Mac OS 等操作系统,具有良好的跨平台性。Pygame 由 Pete Shinners 于 2000 年开发而成,是一款免费、开源的的软件包,因此您可以放心地使用它来开发游戏,不用担心有任何费用产生。
Pygame 在 SDL(Simple DirectMedia Layer,使用 C语言编写的多媒体开发库) 的基础上开发而成,它提供了诸多操作模块,比如图像模块(image)、声音模块(mixer)、输入/输出(鼠标、键盘、显示屏)模块等。相比于开发 3D 游戏而言,Pygame 更擅长开发 2D 游戏,比如于飞机大战、贪吃蛇、扫雷等游戏。
安装pygame
pip install pygame

pygame入门案例
import pygame import sys pygame.init() # 初始化pygame size = width, height = 320, 240 # 设置窗口大小 screen = pygame.display.set_mode(size) # 显示窗口 while True: # 死循环确保窗口一直显示 for event in pygame.event.get(): # 遍历所有事件 if event.type == pygame.QUIT: # 如果单击关闭窗口,则退出 sys.exit() pygame.quit() # 退出pygame
