ElasticEase.Springiness ElasticEase.Springiness ElasticEase.Springiness ElasticEase.Springiness Property

Definition

Gets or sets the stiffness of the spring. The smaller the Springiness value is, the stiffer the spring and the faster the elasticity decreases in intensity over each oscillation.

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

Property Value

A positive number that specifies the stiffness of the spring. The default value is 3.

Examples

The following example applies an ElasticEase easing function to a DoubleAnimation to create an animation that resembles a spring oscillating back and forth until it comes to rest.

<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>

Remarks

The smaller the Springiness value is, the stiffer the spring and the faster the elasticity decreases in intensity over each oscillation.
