示例

import { Group, Leafer, Path, Polygon } from 'leafer-ui'
import '@leafer-in/animate'
import '@leafer-in/motion-path'

const leafer = new Leafer({ view: window })

const group = new Group()

const path = new Polygon({
    x: 100,
    y: 100,
    motionPath: true, // 设置为运动路径，该 Group 内的其他元素都可以沿此路径运动
    points: [0, 90, 100, 60, 200, 80, 300, 40, 375, 50, 450, 10, 550, 90, 550, 90, 0, 90],
    curve: true,
    fill: '#32cd79',
})

const car = new Path({
    scale: 0.03,
    fill: 'black',
    around: 'bottom',
