如何让我的 SVG SMIL 动画再次正确播放?

How can I make my SVG SMIL animation play back correct again?

我是一名编码经验很少的设计师,前段时间我玩过 SMIL 动画,我记得有些浏览器不支持特定命令。现在我想检查我的动画,不幸的是我注意到我最初成功测试动画的浏览器 (opera) 也停止正确播放我的动画。蓝球曾经在 y 轴上上下移动,现在这个动画不工作了。

你们知道为什么这个动画不能再在 codepen 中正确播放吗?我如何才能像以前一样查看动画?

这是似乎不起作用的部分:

<!-- Animating the ball along the Y Axis, with specific y coordinate values relative to time, with speed dependent on bezier curve -->
<animate
           attributeName="cy"
           begin="0.2s"
           dur="1.6s"
           values="142;10;-5;142;142"
           keySplines="
                       0.1 0.9 1.0 1.0; 
                 1.0 1.0 1.0 1.0; 
                       0.5 1.6 0.1 0.9;
                 0.1 0.9 1.0 1.6;" 
           keyTimes="
                       0;0.20;0.40;0.8;1" 
           calcMode="spline"
           repeatCount="indefinite"
           />

你可以看一下控制台,就知道问题出在哪里了。根据 specs for keySplines,

The values of x1 y1 x2 y2 must all be in the range 0 to 1.

您的示例有两个值 1.6。我已将它们更改为 0.6,它在我的浏览器中有效 (Chrome)。
