HTML烟花特效码农代码和人工智能代码对比
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">今天和<span style="color: black;">大众</span>分享一下关于HTML烟花特效的代码。码农手动编辑和人工智能生成的区别，<span style="color: black;">大众</span><span style="color: black;">能够</span>自己对比。下面是我整理的一个简单的代码样例，供<span style="color: black;">大众</span>参考。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">码农编写：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">首要</span>，<span style="color: black;">咱们</span><span style="color: black;">必须</span><span style="color: black;">运用</span>HTML5<span style="color: black;">供给</span>的canvas元素来完成烟花的绘制。其中，<span style="color: black;">触及</span>到<span style="color: black;">有些</span><span style="color: black;">基本</span>的canvas知识，如画布的<span style="color: black;">体积</span>设置、线条的绘制、颜色填充等。代码如下：</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><canvas id="fireworks"></canvas>
<script>
var fireworks = document.getElementById(fireworks);
var ctx = fireworks.getContext(2d);
var width = fireworks.width = window.innerWidth;
var height = fireworks.height = window.innerHeight;
var particles = [];
// 绘制小球
function Particle(x, y, color) {
this.x = x;
this.y = y;
this.color = color || #ffffff;
this.radius = 2;
}
Particle.prototype.draw = function() {
ctx.beginPath();
ctx.arc(this.x, this.y, this.radius, 0, Math.PI * 2, false);
ctx.fillStyle = this.color;
ctx.fill();
};
function loop() {
ctx.fillStyle = rgba(0, 0, 0, 0.2);
ctx.fillRect(0, 0, width, height);
// 产生一个新的烟花
if (Math.random()< 0.03) {
var particle = new Particle(width / 2, height, rgb( + random(255) + , + random(255) + , + random(255) + ));
particles.push(particle);
}
// 绘制并更新小球
for (var i = 0; i< particles.length; i++) {
particles.draw();
particles.y -= 10;
if (particles.y< -10) {
particles.splice(i, 1);
}
}
requestAnimationFrame(loop);
}
// 生成随机数
function random(num) {
return Math.floor(Math.random() * num);
}
loop();
</script></div>
