复杂的SVG动画

Question

我需要像这样制作徽标动画：

这是它的SVG代码：

我花了很多时间寻找解决方案，但大多数时候我偶然发现了中风SVG动画。 Vivus.js看起来是一个很好的解决方案，但它没有为填充路径设置动画，它只适用于笔画。几乎我找到的所有例子都是如此，比如DrawSVG等。 我将SVG分解为简单的元素，因此动画它们会更容易。我想我必须使用一些SVG蒙版，因为我不能通过应用笔画等来改变徽标的现有形状。唯一看起来类似于我的动画是on Codepen。 SVG代码在那里非常复杂，我不确定它的动画方式是否会解决我的问题。

如何为徽标设置动画？

Answer 1

正如评论所建议的那样，建议将图形从形状转换为笔画，然后使用动画库（如Anime JS或Greensock）来执行动画。

转换为笔画

为了转换为笔画，我使用了Illustrator，然后在使用Jake Archibald SVGOMG优化图形之前导出到SVG。

动画示例

我为动画选择了Anime JS库 - 请参阅下面的代码段。

＆＃13;

＆＃13;

anime({
  targets: 'path',
  strokeDashoffset: [anime.setDashoffset, 0],
  easing: [0.550, 0.055, 0.100, 1.000],
  duration: 1500,
  delay: 1200,
  direction:'forwards'
});

＆＃13;

svg {
  display: block;
  width: 300px;
  height: 300px;
  margin: 0 auto;
}
