使用Python绘制跳动的爱心,让你的代码也充满爱意!

今天我要分享一个浪漫小技巧,使用Python中的HTML制作一个立体、动态的小爱心。通过成千上百个小爱心的组合,形成一个大爱心,从内到外呈现出立体的效果,给人带来强烈的视觉冲击。这个小技巧非常浪漫,让人感受到爱的力量。

一.粉色爱心



  
    
    
(function () {
      var b = 0;
      var c = ["ms", "moz", "webkit", "o"];
      for (var a = 0; a < c.length && !window.requestAnimationFrame; ++a) {
        window.requestAnimationFrame = window[c[a] + "RequestAnimationFrame"];
        window.cancelAnimationFrame =
          window[c[a] + "CancelAnimationFrame"] ||
          window[c[a] + "CancelRequestAnimationFrame"];
      }
      if (!window.requestAnimationFrame) {
        window.requestAnimationFrame = function (h, e) {
          var d = new Date().getTime();
          var f = Math.max(0, 16 - (d - b));
          var g = window.setTimeout(function () {
            h(d + f);
          }, f);
          b = d + f;
          return g;
        };
      }
      if (!window.cancelAnimationFrame) {
        window.cancelAnimationFrame = function (d) {
          clearTimeout(d);
        };
      }
    })();

    /*
     *Point class
     */
    var Point = (function () {
      function Point(x, y) {
        this.x = typeof x !== "undefined" ? x : 0;
        this.y = typeof y !== "undefined" ? y : 0;
      }
      Point.prototype.clone = function () {
        return new Point(this.x, this.y);
      };
      Point.prototype.length = function (length) {
        if (typeof length == "undefined")
          return Math.sqrt(this.x * this.x + this.y * this.y);
        this.normalize();
        this.x *= length;
        this.y *= length;
        return this;

        this.x /= length;
        this.y /= length;
        return this;
      };
      return Point;
    })();

    /*
     * Particle class
     */
    var Particle = (function () {
      function Particle() {
        this.position = new Point();
        this.velocity = new Point();
        this.acceleration = new Point();
        this.age = 0;
      }
      Particle.prototype.initialize = function (x, y, dx, dy) {
        this.position.x = x;
        this.position.y = y;
        this.velocity.x = dx;
        this.velocity.y = dy;
        this.acceleration.x = dx * settings.particles.effect;
        this.acceleration.y = dy * settings.particles.effect;
        this.age = 0;
      };
      Particle.prototype.update = function (deltaTime) {
        this.position.x += this.velocity.x * deltaTime;
        this.position.y += this.velocity.y * deltaTime;
        this.velocity.x += this.acceleration.x * deltaTime;
        this.velocity.y += this.acceleration.y * deltaTime;
        this.age += deltaTime;
      };
      Particle.prototype.draw = function (context, image) {
        function ease(t) {
          return --t * t * t + 1;
        }
        var size = image.width * ease(this.age / settings.particles.duration);
        context.globalAlpha = 1 - this.age / settings.particles.duration;
        context.drawImage(
          image,
          this.position.x - size / 2,
          this.position.y - size / 2,
          size,
          size
        );
      };
