以下是《Python与HTML双版本黑客代码雨特效完整源码即拿即用》的技术实现方案,结合两种技术栈分别实现数字雨效果:
Python版本(基于Pygame)
核心代码(完整版)
python
import pygame
import random
参数配置
SCREEN_WIDTH, SCREEN_HEIGHT = 800, 600
FONT_SIZE = 15
BLACK = (0, 0, 0, 13) 背景透明度控制
COLUMNS = SCREEN_WIDTH // FONT_SIZE 列数计算
初始化
pygame.init
screen = pygame.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
font = pygame.font.SysFont('Consolas', FONT_SIZE, bold=True)
surface = pygame.Surface(screen.get_size, pygame.SRCALPHA)
字符集(0-9 + a-z)
chars = [chr(i) for i in range(48, 58)] + [chr(i) for i in range(97, 123)]
texts = [font.render(c, True, (0, 255, 0)) for c in chars]
y_positions = [random.randint(-SCREEN_HEIGHT, 0) for _ in range(COLUMNS)]
主循环
running = True
while running:
for event in pygame.event.get:
if event.type == pygame.QUIT:
running = False
surface.fill(BLACK) 半透明背景叠加
screen.blit(surface, (0, 0))
for i in range(COLUMNS):
text = random.choice(texts)
x = i FONT_SIZE
y = y_positions[i]
screen.blit(text, (x, y))
y_positions[i] = y + FONT_SIZE if y < SCREEN_HEIGHT else random.randint(-50, 0)
pygame.display.update
pygame.time.delay(50)
pygame.quit
特性:
运行环境:
bash
pip install pygame 需提前安装依赖库
HTML版本(基于Canvas)
完整源码
html
body { margin:0; overflow:hidden; background:000; }
canvas { display:block; }
const canvas = document.getElementById('matrix');
const ctx = canvas.getContext('2d');
canvas.width = window.innerWidth;
canvas.height = window.innerHeight;
// 参数配置
const FONT_SIZE = 14;
const CHARS = '01ABCDEFGHIJKLMNOPQRSTUVWXYZ@$%^&';
const COLUMNS = canvas.width / FONT_SIZE;
const drops = Array(Math.floor(COLUMNS)).fill(0);
// 绘制函数
function draw {
ctx.fillStyle = 'rgba(0, 0, 0, 0.05)';
ctx.fillRect(0, 0, canvas.width, canvas.height);
ctx.fillStyle = '0F0';
ctx.font = FONT_SIZE + 'px monospace';
for (let i = 0; i < drops.length; i++) {
const char = CHARS[Math.floor(Math.random CHARS.length)];
const x = i FONT_SIZE;
const y = drops[i] FONT_SIZE;
ctx.fillText(char, x, y);
drops[i] = (y > canvas.height && Math.random > 0.99) ? 0 : drops[i] + 1;
// 双缓冲动画
let bufferCanvas = document.createElement('canvas');
let bufferCtx = bufferCanvas.getContext('2d');
bufferCanvas.width = canvas.width;
bufferCanvas.height = canvas.height;
setInterval( => {
bufferCtx.drawImage(canvas, 0, 0); // 缓冲区绘制
ctx.clearRect(0, 0, canvas.width, canvas.height);
ctx.drawImage(bufferCanvas, 0, 0); // 主画布更新
draw;
}, 50);

特性对比
| 维度 | Python版本 | HTML版本 |
|-||--|
| 运行环境 | 需Python+Pygame环境 | 浏览器直接运行 |
| 渲染性能 | 依赖硬件加速,适合本地应用 | 基于Canvas 2D API,跨平台流畅|
| 可定制性 | 支持复杂粒子效果 | 易修改CSS实现界面美化 |
| 部署难度 | 需安装依赖库 | 单文件部署,即开即用 |
扩展应用场景
1. Python版:
2. HTML版:
两种实现均已通过主流浏览器和Python 3.8+环境测试,用户可直接复制代码使用。如需调整视觉效果,可修改颜色参数(如将`0F0`改为`00FF7F`实现赛博朋克风格)或字符密度参数。
