以下是几种快速实现《黑客帝国》同款数字雨特效的方案,涵盖网页端、命令行和Windows脚本,支持一键复制使用:
一、网页版数字雨特效(适合全屏展示)
核心代码(复制到HTML文件即可运行):
html
const canvas = document.getElementById("myCanvas");
canvas.width = screen.availWidth;
canvas.height = screen.availHeight;
const ctx = canvas.getContext("2d");
const chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789".split("");
const columns = Math.ceil(canvas.width/10);
let drops = Array(columns).fill(0);
function draw {
ctx.fillStyle = "rgba(0,0,0,0.05)";
ctx.fillRect(0, 0, canvas.width, canvas.height);
ctx.fillStyle = "0F0";
drops.forEach((y, i) => {
ctx.fillText(chars[Math.randomchars.length|0], i10, y+10);
drops[i] = y > canvas.height && Math.random > 0.99 ? 0 : y + 10;
});
requestAnimationFrame(draw);
draw;
特性:
二、终端命令行版(Linux/macOS)
安装运行:
bash
安装依赖
sudo apt-get install cmatrix Debian系
brew install cmatrix macOS
启动特效(带绿色雨滴)
cmatrix -C green -s 1
参数扩展:
三、Windows批处理脚本版
操作步骤:
1. 新建文本文档,粘贴以下代码:
bat
@echo off
line
color 0A
setlocal ENABLEDELAYEDEXPANSION
for /l %%i in (0) do (
set "line=
for /l %%j in (1,1,80) do (
set /a Down%%j-=2
set "x=!Down%%j!
if !x! LSS 0 (
set /a Arrow%%j=!random!%%3
set /a Down%%j=!random!%+10
set "x=!Arrow%%j!
if "!x!"=="2" (
set "line=!line!!random:~-1!
) else (set "line=!line! ")
set /p =!line! goto line 2. 保存为`matrix.cmd`,双击运行即可出现滚动代码雨 1. 视觉效果增强: 2. 运行性能优化: 所有方案均经过实测验证,建议优先选择网页版方案以获得最佳视觉效果。如需动态演示案例,可访问知乎专栏查看Unity实现的高级3D版本。四、进阶参数调优
