前言

最近那个电视剧很火,就是搞爱心代码的,本人兴趣使然,在网上搜集了一些代码,经过一定修改,做一个小总结。源文件直接免费下载点此处

一、python

运行

主要用的包都是那么几个,csdn搜pycharm怎么导包就可以。

调整思路

HEART_COLOR = "#EEAEEE"  #引号内修改颜色!颜色代码放在文章末尾

双引号里面可以在csdn搜RGB颜色,比如这个兄弟的,直接看里面的对照表,把包括#的数字或字母替换就可以换颜色了

html的个人感觉更好,因为有浏览器就支持运行,py的后期得导出成exe才可以在没有环境设备运行,html手机电脑都可以的。

调整

<title>canvas爱心</title>   这个canvas爱心字样随便调整可以自己编辑TA的名字之类的

代码如下

  padding: 0;
  margin: 0;
  background: #000;
}
canvas {
  position: absolute;
  width: 100%;

}

      if (firstActive == particles.length) firstActive = 0;
    }
    
    
  };
  ParticlePool.prototype.draw = function(context, image) {
    // draw active particles
    if (firstActive < firstFree) {

        particles[i].draw(context, image);
    }

        particles[i].draw(context, image);
      for (i = 0; i < firstFree; i++)
        particles[i].draw(context, image);
    }
  };
  return ParticlePool;
})();

/*
 * Putting it all together
 */
(function(canvas) {
  var context = canvas.getContext('2d'),
      particles = new ParticlePool(settings.particles.length),
      particleRate = settings.particles.length / settings.particles.duration, // particles/sec

备注

这个我个人感觉还是蛮好看的,值得注意的是,里面的字是也能动的,可以把♥瓜瓜♥改成你想要的字眼(代码里面ctrl+f 找瓜瓜字眼 替换即可),titile也同理

3.第四个html

样例

 代码调整思路

x位置直接记事本打开ctrl+f 找亲爱的 编辑文案

然后对这行字的编辑(样式上)

是这个,改这里的信息就行哪个参数不会就搜一下他的作用 比如第一行是字体,你可以百度html字体 比如这个大佬写的博客,都是一样道理。

总结

本文简单介绍了几种爱心代码,希望对大家有所帮助,求赞欧~~~
另外,python想送给你的那个 TA的话可以打包为exe的,我后期再补一下教程,然后运行有问题的可以在评论区说明~
