WPF关键帧动画
背景:要实现动画已经有关键动画了,但是关键动画如果动画比较复杂,那么就需要重复写多个DoubleAnimation。如果使用上关键帧就可以少写几遍Storyboard里面的属性
普通动画:
<DoubleAnimation From="0" To="30" Duration="0:0:2" BeginTime="0:0:3"Storyboard.TargetName="" Storyboard.TargetProperty="">
使用上关键帧的动画:
<Rectangle x:Name="myRect" Width="50" Height="50" HorizontalAlignment="Left" Fill="Blue"><Rectangle.RenderTransform><TranslateTransform x:Name="myTranslate" X="0" Y="0"/></Rectangle.RenderTransform><Rectangle.Triggers><EventTrigger RoutedEvent="Rectangle.MouseLeftButtonDown"><BeginStoryboard><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetName="myTranslate" Storyboard.TargetProperty="X"Duration="0:0:10"><LinearDoubleKeyFrame Value="100" KeyTime="30%"/><LinearDoubleKeyFrame Value="300" KeyTime="60%"/><LinearDoubleKeyFrame Value="700" KeyTime="70%"/></DoubleAnimationUsingKeyFrames></Storyboard></BeginStoryboard></EventTrigger></Rectangle.Triggers>
</Rectangle>
-- 这里体现的是关键帧作用于X坐标
