【中文标题】摇动动画(3d版)【英文标题】:Shake animation (3d version) 【发布时间】:2015-08-10 11:27:13 【问题描述】:我想在错误上使用这个动画,比如here:
如何在 wpf 中实现这一点?我觉得这应该是多个转换的组合(组合?),但是哪些转换以及具体如何?
这是一个启动器(mcve 或称其为“我的尝试”),它很丑陋,甚至与我想要的都不接近:
<Grid>
<Border x:Name="border"
Width="200"
Height="200"
BorderBrush="Black"
BorderThickness="1"
CornerRadius="4"
Background="LightBlue"
RenderTransformOrigin="0.5,0">
<Border.RenderTransform>
<TransformGroup>
<ScaleTransform />
<SkewTransform />
<RotateTransform />
<TranslateTransform />
</TransformGroup>
</Border.RenderTransform>
<Border.Effect>
<DropShadowEffect BlurRadius="20" />
</Border.Effect>
<Button VerticalAlignment="Bottom"
HorizontalAlignment="Center"
Margin="0,0,0,10"
Padding="5"
Content="Click">
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard FillBehavior="Stop">
<DoubleAnimation Storyboard.TargetName="border"
Storyboard.TargetProperty="RenderTransform.Children[1].(SkewTransform.AngleX)"
To="5" Duration="0:0:0.1"/>
<DoubleAnimation Storyboard.TargetName="border"
Storyboard.TargetProperty="RenderTransform.Children[1].(SkewTransform.AngleX)"
To="-5"
BeginTime="0:0:0.1"
Duration="0:0:0.2" />
<DoubleAnimation Storyboard.TargetName="border"
Storyboard.TargetProperty="RenderTransform.Children[1].(SkewTransform.AngleX)"
To="5"
BeginTime="0:0:0.3"
Duration="0:0:0.2" />
<DoubleAnimation Storyboard.TargetName="border"
Storyboard.TargetProperty="RenderTransform.Children[1].(SkewTransform.AngleX)"
BeginTime="0:0:0.5"
Duration="0:0:0.1" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
</Border>
</Grid>
周围有很多 2d 摇动帖子(click、click),但我需要动画来告诉“你错了”,而不是说“让我们跳舞”的动画。
【问题讨论】:
【参考方案1】:目前为止最好的效果是这样的:
<Grid>
<Border Width="200"
Height="200"
BorderBrush="Black"
BorderThickness="1"
CornerRadius="4"
Background="LightBlue"
RenderTransformOrigin="0.5,0">
<Border.RenderTransform>
<RotateTransform x:Name="transform" />
</Border.RenderTransform>
<Border.Effect>
<DropShadowEffect BlurRadius="20" />
</Border.Effect>
<Button VerticalAlignment="Bottom"
HorizontalAlignment="Center"
Margin="0,0,0,10"
Padding="5"
Content="Click">
<Button.Triggers>
<EventTrigger RoutedEvent="Button.Click">
<BeginStoryboard>
<Storyboard FillBehavior="Stop">
<DoubleAnimation Storyboard.TargetName="transform"
Storyboard.TargetProperty="Angle"
From="5"
Duration="0:0:0.5">
<DoubleAnimation.EasingFunction>
<ElasticEase EasingMode="EaseOut"
Oscillations="2"
Springiness="1" />
</DoubleAnimation.EasingFunction>
</DoubleAnimation>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Button.Triggers>
</Button>
</Border>
</Grid>
这给人一种身临其境的感觉“出了点问题”。在出现更好的答案之前我很满意。

【参考方案2】:这是你描述的动画。我使用Viewport3D
和Viewport2DVisual3D
来托管控件。
您可以使用它来构建您自己的可重复使用的自定义抖动控件。
无法使用简单的 2D RenderTransforms
复制这个精确的动画。
<Grid>
<Viewport3D>
<Viewport3D.Camera>
<PerspectiveCamera Position="0, 0, 4"/>
</Viewport3D.Camera>
<Viewport2DVisual3D x:Name="DVisual3D">
<Viewport2DVisual3D.Transform>
<RotateTransform3D>
<RotateTransform3D.Rotation>
<AxisAngleRotation3D Angle="0" Axis="0, 1, 0" />
</RotateTransform3D.Rotation>
</RotateTransform3D>
</Viewport2DVisual3D.Transform>
<Viewport2DVisual3D.Geometry>
<MeshGeometry3D Positions="-1,1,0 -1,-1,0 1,-1,0 1,1,0"
TextureCoordinates="0,0 0,1 1,1 1,0" TriangleIndices="0 1 2 0 2 3"/>
</Viewport2DVisual3D.Geometry>

<Border x:Name="border"

<DoubleAnimation Storyboard.TargetName="DVisual3D"
Storyboard.TargetProperty="Transform.(RotateTransform3D.Rotation).(AxisAngleRotation3D.Angle)"

</Viewport3D>
【讨论】:
看起来不错,谢谢。我不确定这是否合适(必须检查使用ViewPort3D
的缺点),但动画看起来与想要的相似。以上是关于摇动动画(3d版)的主要内容,如果未能解决你的问题,请参考以下文章
使用 jQuery 触发 CSS 摇动动画,每隔一段时间都有效……为啥?
