motion-advanced

用于 React/Next.js 的高级动效模式——拖拽、手势、文字动画、SVG 路径绘制、自定义钩子、指令式序列 (useAnimate)、加载器以及完整的 API 决策树。需要先配置 motion-foundations。在构建拖拽、手势、文字或 SVG 动画,或在 React 或 Next.js 中构建指令式动画序列时使用。

motion-advanced 是什么?

该技能提供了一套高级、基于物理的动画模式,适用于使用 motion 库的 React/Next.js 项目。它扩展了更基础的 motion-patterns 技能,用于处理复杂的交互,包括拖拽、手势、逐字/逐字符文字动画、SVG 路径绘制、自定义动画钩子、指令式动画序列和加载器组件。技能文档提供了一个完整的 API 决策树,帮助根据具体场景(如拖拽、滑动、长按)选择正确的 API,并通过详细规则强调了关键实践,例如触摸设备测试、无限动画的可见性管理、滑动阈值准确取值、motion 值的 SSR 安全使用,以及通过 useEffect 进行手柄清理。通过丰富的 TypeScript 代码示例,该技能展示了如何实现拖拽卡片、可拖拽关闭面板、可排序列表、滚动揭示、鼠标跟随器、计数器和骨架屏等组件,并始终强调从 motion-foundations 导入标记值,以确保一致性和性能。

文档

Motion 高级

复杂、交互式、基于物理的动画模式。 需要先配置 motion-foundations。 当 motion-patterns 不够用时使用。

何时激活

  • 构建拖拽关闭的抽屉、滑动手势或可重新排序的列表
  • 逐词、逐字动画文本,或作为实时计数器
  • 绘制 SVG 路径、图标变形或动画圆形进度
  • 编写自定义动画钩子(useScrollReveal、磁性按钮、鼠标跟随器)
  • 使用 useAnimate 指令式地编排多步骤动画序列
  • 构建微调器、 shimmer 骨架屏、脉冲指示器或按钮加载状态

输出

该技能产生:

  • 拖拽交互:可拖拽卡片、拖拽关闭的抽屉、Reorder.Group 列表
  • 手势钩子:滑动检测、长按、收缩轮廓
  • 文字动画组件:逐词揭示、打字机效果、数字计数器
  • SVG 动画:路径绘制、图标变形、描边进度环
  • 自定义钩子:useScrollReveal、useHoverScale、useNavigationDirection、useInViewOnce
  • 通过 useAnimate 实现的指令式序列,支持中断安全的 async/await
  • 加载器组件:微调器、shimmer、脉冲点、进度条、按钮加载状态

原则

  • 对于直接操控,基于物理的运动(useSpring、springs.*)总是比基于持续时间的运动感觉更自然。
  • useMotionValue + useTransform 计算派生值而不触发重新渲染。
  • useAnimate 序列是指令式和中断安全的——在动画执行过程中调用 animate() 会自动取消前一个动画。
  • 运动值(useMotionValue、useSpring)是 SSR 安全的,不会导致水合错误。

规则

  1. 拖拽交互必须在触摸设备上进行测试,而不仅仅是鼠标。drag 属性在两者上都有效,但手感和阈值不同。
  2. 当 document.visibilityState === "hidden" 时,无限动画必须暂停。 后台标签页不得消耗 GPU/CPU。
  3. 滑动阈值必须明确。 切勿仅凭速度推断意图;应结合 offset + velocity 检查。
  4. useAnimate 作用域 ref 必须附加到已挂载的 DOM 元素上。 在挂载前调用 animate() 会静默失败。
  5. 运动值不得在渲染时重新创建。 在组件主体内部使用 useMotionValue(0) 是正确的;在渲染中使用 new MotionValue(0) 是不正确的。
  6. 所有标记值均从 motion-foundations 导入。 不允许使用内联数字。
  7. 自定义钩子必须处理清理工作。 每个 window.addEventListener 都需要在 useEffect 的返回函数中有一个匹配的 removeEventListener。
  8. SVG 变形需要相同的路径命令数量。 具有不同命令结构的路径会直接跳变而不是插值。

决策指导

选择正确的高级 API

场景API
释放时带物理效果的拖拽drag + dragTransition: springs.release
可排序拖拽的列表Reorder.Group + Reorder.Item
根据拖拽偏移量关闭drag="y" + onDragEnd 偏移量检查
左/右滑动drag="x" + onDragEnd 偏移量检查
长按useLongPress 钩子
随时间平滑的值useSpring
从另一个值派生的值useTransform
多步骤序列useAnimate 配合 async/await
单次指令式动画animate() 来自 motion
逐词文本进入在 inline-block 范围内交错延迟
SVG 绘制pathLength 0 → 1
SVG 变形d 属性补间(命令数相等)
圆形进度strokeDashoffset 补间

何时使用 useSpring 与弹簧过渡

useSpringtransition: springs.*
用于鼠标跟随器、指针跟踪值离散状态变化
更新方式连续,每帧更新由状态变化触发
中断平滑——物理效果从当前速度开始从当前值重新开始

核心概念

useMotionValue + useTransform

无重新渲染的反应式计算:

const x = useMotionValue(0)
const opacity = useTransform(x, [-200, 0, 200], [0, 1, 0])
// opacity 每帧更新,随着 x 变化——无需 setState,无需重新渲染

useAnimate

返回 [scope, animate]。scope ref 必须附加到 DOM 元素上。 animate() 调用是中断安全的——在动画执行过程中调用会取消前一次运行。

const [scope, animate] = useAnimate()

async function play() {
  await animate(".step-1", { opacity: 1 }, { duration: 0.3 })
  await animate(".step-2", { x: 0 },       { duration: 0.4 })
        animate(".step-3", { scale: 1 },    { duration: 0.25 })  // 触发并忽略
}

return <div ref={scope}>...</div>

代码示例

可拖拽卡片

"use client"
import { motion } from "motion/react"
import { springs, motionTokens } from "@/lib/motion-tokens"

<motion.div
  drag
  dragConstraints={{ left: -100, right: 100, top: -100, bottom: 100 }}
  dragElastic={0.1}
  whileDrag={{
    scale: motionTokens.scale.pop,
    boxShadow: "0 16px 40px rgba(0,0,0,0.2)",
  }}
  dragTransition={springs.release}
/>

拖拽关闭的抽屉

"use client"
import { motion, useMotionValue, useTransform } from "motion/react"

export function BottomSheet({ onClose }: { onClose: () => void }) {
  const y = useMotionValue(0)
  const opacity = useTransform(y, [0, 200], [1, 0])

  return (
    <motion.div
      drag="y"
      dragConstraints={{ top: 0 }}
      style={{ y, opacity }}
      onDragEnd={(_, info) => {
        // 规则 3:结合偏移量 + 速度
        if (info.offset.y > 120 || info.velocity.y > 500) onClose()
      }}
    />
  )
}

"use client"
import { Reorder } from "motion/react"

export function SortableList() {
  const [items, setItems] = useState(initialItems)
  return (
    <Reorder.Group axis="y" values={items} onReorder={setItems}>
      {items.map((item) => (
        <Reorder.Item key={item.id} value={item}>
          {item.label}
        </Reorder.Item>
      ))}
    </Reorder.Group>
  )
}

  dragConstraints={{ left: 0, right: 0 }}
  onDragEnd={(_, info) => {
    const swipedRight = info.offset.x > OFFSET_THRESHOLD  || info.velocity.x > VELOCITY_THRESHOLD
    const swipedLeft  = info.offset.x < -OFFSET_THRESHOLD || info.velocity.x < -VELOCITY_THRESHOLD
    if (swipedRight) onSwipeRight()
    if (swipedLeft)  onSwipeLeft()
  }}
/>
