如何在UWP中设置偏移路径?例如,使用CreateExpressionAnimation
。
我有四个静态位置的图像,我需要其他图像来动画一次跳过这四个图像。
目前我正在使用CreateVector3KeyFrameAnimation
并更改四个图像的偏移量,但我需要一个弧形效果。

这应该可以在故事板中使用3个时间轴 - 1个x轴平移,没有缓动持续动画的整个持续时间,然后2个y轴平移一个接一个地持续动画时间的一半,第一个一个使用CircleOut缓动(到弧的高度),然后使用CircleIn缓动(返回0)。

我用以下代码测试:
<Storyboard x:Name="ImageStoryboard">
<DoubleAnimationUsingKeyFrames
Storyboard.TargetName="ImageTransform"
Storyboard.TargetProperty="X"

<LinearDoubleKeyFrame Value="890" KeyTime="0:0:9"/>
<LinearDoubleKeyFrame Value="378" KeyTime="0:0:12"/>
</DoubleAnimationUsingKeyFrames>
