python实现代码雨（黑客帝国既视感）

1.运行效果 ：

2.代码：`#首先引入相关模块
import random
import pygame

创建一个可是窗口

PANEL_width = 600
PANEL_highly = 500
FONT_PX = 15

pygame.init()
#设计
winSur = pygame.display.set_mode((PANEL_width, PANEL_highly))

font = pygame.font.SysFont(“123.ttf”, 25)

bg_suface = pygame.Surface((PANEL_width, PANEL_highly), flags=pygame.SRCALPHA)

pygame.Surface.convert(bg_suface)
#颜色、字体的密度
bg_suface.fill(pygame.Color(0, 0, 0, 28))
winSur.fill((0, 0, 0))

数字版

texts = [font.render(str(i), True, (0, 255, 0)) for i in range(10)]

字母版

letter = [‘q’, ‘w’, ‘e’, ‘r’, ‘t’, ‘y’, ‘u’, ‘i’, ‘o’, ‘p’, ‘a’, ‘s’, ‘d’, ‘f’, ‘g’, ‘h’, ‘j’, ‘k’, ‘l’, ‘z’, ‘x’, ‘c’,
‘v’, ‘b’, ‘n’, ‘m’]
texts = [
font.render(str(letter[i]), True, (0, 255, 0)) for i in range(26)
]

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

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] += 1
    if drops[i] * 10 > PANEL_highly or random.random() > 0.95:
        drops[i] = 0

pygame.display.flip()`
