HTML代码
html部分代码比较简单，引入了一个<div>块，设置了CSS样式
<!DOCTYPE html>
<html lang="en" >
<head>
<meta charset="UTF-8">
<title>HTML5 Canvas千纸鹤动画特效</title>
<link rel="stylesheet" href="css/style.css">
</head>
<body>
<div id="controls"></div>
<script src='js/p5.min.js'></script>
<script src="js/index.js"></script>
</body>
</html>
CSS代码
* { margin:0; padding:0; }
html, body { width:100%; height:100%; overflow: hidden; background:black;}
canvas { display:block; }
#controls {
z-index: 2;
margin: 20px;
position: absolute;
top: 0; left: 0;
color: white;
}
js部分代码
index.js
function randColor(base = 0, amt=.2){
return [(base+random(amt)-amt/2)%1, .2 + random(amt), .8 + random(amt)];
}
function setup (){
pixelDensity(1);
createCanvas();
colorMode(HSB, 1, 1, 1);
windowResized();
}
function init(){
birds = [];
for (let i = 0; i < numBirds; i++) birds.push(new Bird());
birds = birds.sort((a,b) => a.size - b.size);
}
function draw(){
background(0, .5);
birds.map(b => b.render());
}
function mousePressed(){windowResized();}
function windowResized(){
resizeCanvas(windowWidth, windowHeight);
init();
}
