不知道如何编码的设计师如何创建svg动画？使用Adobe Animate CC和Animate SVG Exporter进行了尝试，但是将.fla文件导出到svg时，它将失去全部或大部分动画。

SVG smil动画

假设您有这个svg 

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
 width="50%" height="50%" viewBox="0 0 47.4 47.7" style="enable-background:new 0 0 47.4 47.7;" xml:space="preserve">
<style type="text/css">
    .st0{fill-rule:evenodd;clip-rule:evenodd;fill:none;stroke:#FEC558;stroke-width:0.5;stroke-miterlimit:22.9256;}
    .st1{fill:#FFC656;}
</style>
<path class="st0"   d="M23.7,45.8c12.1,0,22-9.9,22-22c0-12.1-9.9-22-22-22c-12.1,0-22,9.9-22,22C1.7,35.9,11.6,45.8,23.7,45.8z"/>
    <g>
        <polygon class="st1"
		  points="14.1,17.9 14.1,20.2 14.1,22.2 14.1,23.4 14.1,24.7 14.1,27.6 32.7,35.2 32.7,32.5 32.7,30.7 
                32.7,29.7 32.7,28.5 32.7,25.2   "/>
        <polygon class="st1"
    		points="19.2,18.7 24.3,20.6 27.5,21.9 27.5,21.2 27.5,19.4 27.5,17.5 27.5,16.3 27.5,15.2 27.5,12.5       15.5,17.2 19.2,18.7"/>
    </g>
</svg>

  • 使用JS确定对象的长度

    <script> function TotalLength(){ var path = document.querySelector('#circle'); var len = Math.round(path.getTotalLength() ); alert("path length - " + len); }; </script>

    路径长度：

    圈-138px

    对于梯形-60px

    对于三角形-35px

    • 用于绘制对象动画的命令

<animate id="an_circle" attributeName="stroke-dashoffset" values="138;0" dur="2s" fill="freeze" />

<animate id="an_trap" attributeName="stroke-dashoffset" values="60;0" dur="1s" fill="freeze" />

<animate id="an_triangle" attributeName="stroke-dashoffset" begin="an_trap.end" values="35;0" dur="1s" fill="freeze" />

  • 绘制三角形的动画将在 梯形图

    begin="an_trap.end"

  • 动画填充颜色梯形将在动画为 完成画一个圆

    <animate id="fill_trap" attributeName="fill" values="#33363D;#FEC558" begin="an_circle.end" dur="1s" fill="freeze" />

  • 当 梯形末端的填充动画

    <animate id="fill_triangle" attributeName="fill" values="#33363D;#FEC558" begin="fill_trap.end-0.5s" dur="1s" fill="freeze" /> 

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"

CSS解决方案

  • 使用CSS实现用于绘制形状轮廓的动画 规则：

为圈子 

.circle {
    fill:none;
    stroke:#FEC558;
    stroke-dashoffset:138.5;
    stroke-dasharray:138.5;
    animation: circle_stroke 2s ease-in forwards;
        } 

    @keyframes circle_stroke {
    0% {
    stroke-dashoffset: 138.5;
    }
    100% {
    stroke-dashoffset: 0;
      }
    }
  • 动画梯形轮廓图并为其填充颜色

下面的代码

.trap {
    stroke-dashoffset:60;
    stroke-dasharray:60;
        animation:trap_stroke 2s ease-in-out forwards,  trap_fill  ease-in 3s forwards;

    }

    @keyframes trap_stroke {
    0% {
    stroke-dashoffset: 60.5;
    }

      100% {
    stroke-dashoffset: 0;
      }
    }  

    @keyframes trap_fill {
    0% {
    fill: none;
    }

      100% {
    fill: #FEC558;
      }
    }

完整的动画代码

   stroke:#FEC558;
