TargetProperty:目标属性
TargetName:目标名称
From:指向属性的初始值;(可省略)
To/By:(二选一)
To:指向属性动画完成后的值;(可省略)
By:指向属性初始值增加的值;(可省略)
Duration:动画执行时间:格式:hh:mm:ss(如:0:0:1表示动画执行1s)
AutoReverse:时间线(动画)达到Duration终点时是否倒退(true/false)
RepeatBehavior:表示时间线(动画)播放次数
·Forever:表示动画一直运行;
·RepeatBehavior = "3x":表示动画执行3次(次数后面加‘x’作为原意字符)
·"[天.]hh:mm:ss[.秒的小数部分]":等于此格式表示 动画重复执行时间
例(利用时间触发器):
<StackPanel x:Name="abc"> <Rectangle x:Name="rect" Width="0" Height="100"> <Rectangle.Fill> <SolidColorBrush Color="Blue"/> </Rectangle.Fill> <Rectangle.Triggers> <EventTrigger RoutedEvent="Loaded">//加载事件触发器 <BeginStoryboard> <Storyboard RepeatBehavior="Forever" AutoReverse="True">//设置动画倒退并无限播放 <DoubleAnimation Storyboard.TargetName="rect"//目标属性名称 Storyboard.TargetProperty="Width"//设置目标属性 From="100" To="200" Duration="0:0:3" />//From:设置初始属性的值 To:设置最后的属性的值 Duration:设置动画播放时间为3s </Storyboard> </BeginStoryboard> </EventTrigger> </Rectangle.Triggers> </Rectangle> </StackPanel>
2.[Storyboard]动画类型属性:
DoubleAnimation:变化动画
·TarnslateTransform:实现偏移动画
·RotateTransform:实现旋转动画
·ScaleTransform:实现缩放动画
例:
<Canvas x:Name="canvasS" Loaded="Canvas_Loaded"> <Canvas.Resources> <Storyboard x:Key="storyBoard"> <DoubleAnimation Storyboard.TargetName="scaleTransfrom" Storyboard.TargetProperty="ScaleY" From="1" To="2" Duration="0:0:3" //设置scaleTransfrom沿Y轴放大两倍 AutoReverse="True" RepeatBehavior="Forever"/> </Storyboard> </Canvas.Resources> <Rectangle x:Name="rectangle" Height="50" Width="50" Canvas.Left="75" Canvas.Top="75" Fill="Blue"> <Rectangle.RenderTransform> <ScaleTransform x:Name="scaleTransfrom"/>//设置属性名称为ScaleTransform
</Rectangle.RenderTransform>
</Rectangle>
</Canvas>
private void Canvas_Loaded(object sender, RoutedEventArgs e)
{
rectangle.BeginStoryboard((Storyboard)canvasS.Resources["storyBoard"]);
}
ColorAnimation:颜色渐变动画
例1(利用事件,在后台事件控制播放动画):
<Window.Resources> <Storyboard x:Key="storyboard1"> <ColorAnimation From="Red" To="Yellow" //从红色渐变成黄色 Storyboard.TargetName="button1" Storyboard.TargetProperty="(Button.Background).(SolidColorBrush.Color)" //(Button.Background).(SolidColorBrush.Color)表示目标属性为Button.Background类型为SolidColorBrush.Color的Color属性 Duration="0:0:5" ></ColorAnimation> </Storyboard> </Window.Resources> <Grid> <Button x:Name="button" Content="start" Margin="10,10,10,0" VerticalAlignment="Top" Click="button_Click"/> <Button x:Name="button1" Content="Test" Margin="10,41,10,0" VerticalAlignment="Top"/> </Grid> private void button_Click(object sender, RoutedEventArgs e) { button1.BeginStoryboard((Storyboard)this.Resources["storyboard1"]); }
例2(使用触发器控制播放动画):
<Button Content="Another Button" Height="30" Width="200" HorizontalAlignment="Left"> <Button.Background> <SolidColorBrush x:Name="myAnimatedBrush" Color="Blue" /> </Button.Background> <Button.Triggers> <!-- Animates the color of the brush used to paint the second button from red to blue . --> <EventTrigger RoutedEvent="Button.Click"> <BeginStoryboard> <Storyboard> <ColorAnimation Storyboard.TargetName="myAnimatedBrush" Storyboard.TargetProperty="Color" From="Red" To="Blue" Duration="0:0:7" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Button.Triggers> </Button>
PointAnimation:Path图形动画
在PathGeometry创建图形,改变图形中的某些点实现动画
例:扇形动画
利用四条曲线组合成一个圆,最后用一条直线连接圆心组成一个闭合图形,控制第三个扇形的第三个点,实现小精灵张嘴闭嘴的动画
<Window.Resources> <Storyboard x:Name="storyboard1" x:Key="storyBoard"> <PointAnimation From="60,10" To="100,50" Duration="0:0:2" Storyboard.TargetName="bezierSegment" Storyboard.TargetProperty="Point3" RepeatBehavior="5" AutoReverse="True" /> </Storyboard> </Window.Resources> <StackPanel x:Name="path" Loaded="StackPanel_Loaded"> <Button Content="运行动画" Click="Button_Click"/> <Path Fill="#FF4080FF" HorizontalAlignment="Left" Height="100" Width="100" Margin="162,164,0,0" VerticalAlignment="Top" Stretch="Fill"> <Path.Data> <PathGeometry> <PathFigure StartPoint="100,50"> <BezierSegment Point1="100,77.6142" Point2="77.6142,100" Point3="50,100"></BezierSegment> <BezierSegment Point1="22.3858,100" Point2="0,77.6142" Point3="0,50"></BezierSegment> <BezierSegment Point1="0,22.3858" Point2="22.3858,0" Point3="50,0"></BezierSegment> <BezierSegment x:Name="bezierSegment" Point1="77.6142,0" Point2="100,22.3858" Point3="100,50"></BezierSegment> <LineSegment Point="50,50"/> <!--形成一个闭合图形--> </PathFigure> </PathGeometry> </Path.Data> </Path> </StackPanel> private void Button_Click(object sender, RoutedEventArgs e) { path.BeginStoryboard((Storyboard)this.Resources["storyBoard"]); }
