SVG路径绘制动画-用anime.js绘制线条，如何防止线条重叠

Question

我使用 anime.js 绘制了以下 SVG 线条图，但由于某些原因，线条在动画过程中似乎重叠。我尝试了所有设置，包括删除 loop、更改 direction 等等，但我所做的任何更改似乎都对此没有影响。根据文档，strokeDashoffset 参数是此类动画的设置，但我找不到与此相关的其他文档。

会不会是 SVG 本身？

Answer 1

你的js没有问题，问题是svg。

我在 illustrator 中打开了你的 SVG，正如你从放大的屏幕截图中看到的那样，每条路径实际上都是一条非常细的闭合路径，所以动漫“正确地”在每条路径的外部绘制！
