像蜗牛一样的路径上的SVG动画 [英] SVG animation on path like the snail

问题描述

我有以下SVG，我想在移动后在路径上逐像素绘制圆圈。就像蜗牛走了一样，他在他身后留下了痕迹。所以我的问题是如何绘制浅红色的圆圈？

I have the following SVG and I would like to draw the circles pixel by pixel on the path after moveing. It's like when the snail goes he let a streak behind him. So my question is how to draw the light red circles?

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" viewBox="0 0 1000 200" id="svgBox" style="background-color:#e4e4e4">
    <path d="M3.858,58.607 c16.784-5.985,33.921-10.518,51.695-12.99c50.522-7.028,101.982,0.51,151.892,8.283c17.83,2.777,35.632,5.711,53.437,8.628 c51.69,8.469,103.241,11.438,155.3,3.794c53.714-7.887,106.383-20.968,159.374-32.228c11.166-2.373,27.644-7.155,39.231-4.449L10,10" stroke="grey" stroke-width="1" fill="none" id="animateMotion"/>
    <circle cx="" cy="" r="5" fill="red">
        <animateMotion dur="6s" repeatCount="0">
            <mpath xlink:href="#animateMotion"/>
        </animateMotion>
    </circle>
</svg>

推荐答案

您可以对实例执行以下操作：

You can do something like this for an instance:

.path {
  stroke-dasharray: 1230;
  stroke-dashoffset: 1230;
  animation: snail 6s linear forwards;
}

@keyframes snail {
  to {
    stroke-dashoffset: 0;
  }
}

        <circle cx="" cy="" r="5" fill="red">
            <animateMotion dur="6s" repeatCount="0">
                <mpath xlink:href="#animateMotion"/>
            </animateMotion>
