ElasticEase.Springiness 屬性

定義

命名空間:

System.Windows.Media.Animation

組件:

PresentationCore.dll

取得或設定彈簧的僵硬度。 Springiness 值越小，彈簧就越僵硬，而且每次振動的彈性強度也會更快增加。

public:
 property double Springiness { double get(); void set(double value); };

public double Springiness { get; set; }

member this.Springiness : double with get, set

Public Property Springiness As Double

屬性值

Double

指定彈簧硬度的正數。 預設值是 3。

範例

下列範例會將 ElasticEase Easing 函式套用至 DoubleAnimation ，以建立類似回溯回應的動畫，直到靜止為止。

<Rectangle Name="myRectangle" Width="200" Height="30" Fill="Blue">
    <Rectangle.Triggers>
        <EventTrigger RoutedEvent="Rectangle.MouseDown">
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation From="30" To="200" Duration="00:00:4" 
                     Storyboard.TargetName="myRectangle" 
                     Storyboard.TargetProperty="Height">
                        <DoubleAnimation.EasingFunction>
                            
                            <!-- Elastic easing function assigned to From/To animation -->
                            <ElasticEase x:Name="myElasticEase" Oscillations="3" 
                             Springiness="1" EasingMode="EaseOut"/>
                        </DoubleAnimation.EasingFunction>
                    </DoubleAnimation>

                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Rectangle.Triggers>

</Rectangle>

備註

值越 Springiness 小，彈簧越硬，彈性越快會隨著每個震動而降低強度。
