motion

运动位置。

注意事项

需安装 运动路径插件 才能使用，另外路径动画功能 需安装 动画插件 。

关键属性

motion: number ｜ IUnitData

定位元素在 运动路径 上的位置，可使用百分比类型, 默认空。

rect.motion = {
  type: 'percent',
  value: 0.5, // 50%
}

motionRotation: number | boolean

偏移运动旋转角度，在运动角度上增加角度， 默认为 0。

元素运动时会设置元素的 rotation 来适应路径方向的变化。

设为 false 时，表示不设置元素的 rotation。

import '@leafer-in/motion-path'
import '@leafer-in/animate'

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

const group = new Group()

const path = new Path({
    x: 100,
    y: 100,
    scale: 0.2,
    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
    stroke: 'black',
    strokeWidth: 20,
    animation: {  // 沿 path 运动描边至 100%
        style: { motion: { type: "percent", value: 1 } },
