我正在使用Popmotion、Pose和flubberpaths在 React Route 更改之间对 SVG 的两个进行变形和过渡。

这完美地工作

import posed from 'react-pose';
import { tween, easing } from 'popmotion';
import { interpolate } from 'flubber';

const pathIds = Object.keys(paths);

const morphTransition = ({ from, to }) =>
  tween({
    from: 0,
    to: 1,
    duration: 1000,
    ease: easing.easeInOut
  }).pipe(interpolate(from, to));

const Background = posed.path(
  pathIds.reduce((config, id) => {
    const path = paths[id].path;
    config[id] = {
      d: path,
      transition: morphTransition
    };
    return config;
  }, {})
);

路径定义为

const paths = {
  first: {
    path:
      'M 262.9,252.2 C 210.1,338.2 212.6,487.6 288.8,553.9 372.2,626.5 511.2,517.8 620.3,536.3 750.6,558.4 860.3,723 987.3,686.5 1089,657.3 1168,534.7 1173,429.2 1178,313.7 1096,189.1 995.1,130.7 852.1,47.07 658.8,78.95 498.1,119.2 410.7,141.1 322.6,154.8 262.9,252.2 Z',

    pathAlt:

  }
};

在路线更改时，效果是 页面 SVG 过渡

但是，我怎么能在所有其他时间之间循环paths[id].path和变形。paths[id].pathAlt例如，我试图通过不断移动的codrops 来实现此处显示的结果。svg

当您更改 url 时，找出哪个函数正在改变形状。

然后在 setInterval() 中使用该函数在路径和路径替代之间交替，而不是不同的路径。
