抱歉,伙计,最近太忙了……不过既然是星期五,让我们尽快帮你整理一下吧,在不久的将来,我们俩都值得喝啤酒。 :)
所以...您想让您的 Storyboard 具有通用性,这样您就不必一直定位特定的命名对象,对吗?好吧,让我们通过打开整个TargetType 来接受我们的出价并让这些小虫子乖乖听话。
使用我在上一个示例中给您的示例,我将重新使用相同的路径数据等。除了注意我们已经从唯一的对象中获取了所有显式渲染声明,而是将它们隐式化。这样一来,它并不关心它击中的是哪个Rectangle...如果它是Rectangle,那么它就会被移动,因为我们已经将它全部移动到一个不可知的风格中,控制TargetType而不是@987654325 @像这样;

您会注意到我留下的大部分内容与前面的示例相同......现在,它并不关心有多少 Rectangle 对象。或者何时或如何添加它们。当一个出现时,我们像老板一样移动它。
希望这对您有所帮助,祝您周末愉快,干杯! :)
哦,PS,没有必要在每个路径上都有那个 xmlns 命名空间。如果你想稍微清理一下你的东西,你可以通过改变 this 的每个实例,用一行来完成同样的事情;
<Path xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="path139746" Fill="#FFD3BC5F" Canvas.Left="399.4" Canvas.Top="-172.6">
<Path.Data>
<PathGeometry Figures="m 66.611178 552.33853 ... z" FillRule="nonzero"/>
</Path.Data>
</Path>
到这个;
<Path Name="path139746" Fill="#FFD3BC5F" Canvas.Left="399.4" Canvas.Top="-172.6" Data="m 66.611178 552.33853 ..... z"/>
...除非有什么特别的理由让它这么长?
另一个提示是,如果您不需要转换组,只需点击特定的转换,例如 Translate。
附录:
假设您想在 Style+Elsewhere 中使用该样式。它现在的构建方式只是为了快速模块化示例。但是,例如,您可以将整个内容放入资源字典中,并在 x:Key 中提供以供参考。所以如果你把它扔到 Resource 字典中,那么第一行就会变成这样;
<Style x:Key="NiftyRectangleAnim" TargetType="{x:Type Rectangle}">
所以现在你可以将它放在一个地方,假设你想将它应用到用户控件上的所有 Rectangle 实例。那么你只需添加这样的东西;
<UserControl.Resources>
<Style TargetType="{x:Type Rectangle}" BasedOn="{StaticResource NiftyRectangleAnim}"/>
</UserControl.Resources>
然后,该 UserControl 上可用的所有 Rectangle 都将继承该样式并进行动画处理。
或者说你只是想使用故事板,然后你会把它从样式中拉出来,然后把它放在其他可以在层次结构中引用的资源中。就像(伪)你可以把这个位扔到需要继承的任何地方;
<Blah.Resources>
<Storyboard x:Key="Weeeee"............./>
</Blah.Resources>
并以您使用的 Storyboard.Begin 方式应用。您仍然会将样式的其余部分应用于 Rectangle 对象(不包括 Style.Triggers),因此它们都将获得必要的 Transform 声明,但故事板不一定必须包含在 Style 模板中。
希望更有意义,这是一个有点难以解释的概念,但不,你不一定必须在 Style.Resources 中有故事板,我只是这样做了,所以你可以复制/粘贴整个内容在一个窗口,看到它去。不过,您需要对使用资源/继承层次结构和您尝试做的事情有一定的经验。
