html5黑客帝国下面代码大概什么意思呀。谢啦
HTML：
canvas id="c"/canvas
CSS：
canvas {display: block;}
JS：
var c = document.getElementById("c");
var ctx = c.getContext("2d");
//全屏
c.height = window.innerHeight;
c.width = window.innerWidth;
//文字
var txts = "0123456789";
//转为数组
txts = txts.split("");
var font_size = 16;
var columns = c.width/font_size;
//用于计算输出文字时坐标，所以长度即为列数
var drops = [];
//初始值
for(var x = 0; x columns; x++)
drops[x] = 1;
//输出文字
function draw()
//让背景逐渐由透明到不透明
ctx.fillStyle = "rgba(0, 0, 0, 0.05)";
ctx.fillRect(0, 0, c.width, c.height);
ctx.fillStyle = "#0F0"; //文字颜色
ctx.font = font_size + "px arial";
//逐行输出文字
for(var i = 0; i drops.length; i++)
//随机取要输出的文字
var text = txts[Math.floor(Math.random()*txts.length)];
//输出文字，注意坐标的计算
ctx.fillText(text, i*font_size, drops[i]*font_size);
//如果绘满一屏或随机数大于0.95（此数可自行调整，效果会不同）
if(drops[i]*font_size c.height || Math.random() 0.95)
drops[i] = 0;
//用于Y轴坐标增加
drops[i]++;
setInterval(draw, 33);
解释了的很详细了。
