用python实现代码雨：
# -*- coding:utf-8 -*-import randomimport pygamefrom pygame.locals import *from sys import exitPANEL_width = 1920PANEL_highly = 1080FONT_PX = 40pygame.init()# 创建一个可视窗口, 如果不想全屏运行，可以把 FULLSCREEN 参数去掉winSur = pygame.display.set_mode((PANEL_width, PANEL_highly), FULLSCREEN, 32)font = pygame.font.SysFont("SimHei", 35)bg_suface = pygame.Surface((PANEL_width, PANEL_highly), flags=pygame.SRCALPHA)pygame.Surface.convert(bg_suface)bg_suface.fill(pygame.Color(0, 0, 0, 20))winSur.fill((0, 0, 0))# 数字版# texts = [font.render(str(i), True, (0, 255, 0)) for i in range(10)]# # 二进制版# letter = ['1', '0', '1', '1', '1', '0', '0', '0', '1', '0', '1', '0', '1', '0', '0', '1', '1', '0', '0', '0', '1', '1'# ,'1', '0', '1', '0', '0', '1', '0', '1']# # 汉字版,但看不到字# letter = ['我', '爱', '你', '我', '爱你', '我爱你', '我非常爱你', '我爱你', '我爱', '我', '爱', '你',# '我爱你', '爱', '我', '爱你', '我', '我爱', '爱你', '你']## # 字母版letter = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v','w', 'x', 'y', 'z']texts = [font.render(str(letter[i]), True, (0, 255, 0)) for i in range(20)]# 按屏幕的宽带计算可以在画板上放几列坐标并生成一个列表column = int(PANEL_width / FONT_PX)drops = [0 for i in range(column)]while True:# 从队列中获取事件, 如果退出程序, 按两下确认键即可for event in pygame.event.get():if event.type == pygame.QUIT:exit()elif event.type == pygame.KEYDOWN:chang = pygame.key.get_pressed()if (chang[32]):exit()# 将暂停一段给定的毫秒数pygame.time.delay(30)# 重新编辑图像第二个参数是坐上角坐标winSur.blit(bg_suface, (0, 0))for i in range(len(drops)):text = random.choice(texts)# 重新编辑每个坐标点的图像winSur.blit(text, (i * FONT_PX, drops[i] * FONT_PX))drops[i] += 1if drops[i] * 10 > PANEL_highly or random.random() > 0.95:drops[i] = 0pygame.display.flip()
实现效果截图如下：
