CubicEase Class

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Represents an easing function that creates an animation that accelerates and/or decelerates using the formula f(t) = t3.

Properties

Name Description
Dispatcher Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
EasingMode Gets or sets a value that specifies how the animation interpolates. (Inherited from EasingFunctionBase.)

Methods

Name Description
CheckAccess Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject.)
Ease Transforms normalized time to control the pace of an animation. (Inherited from EasingFunctionBase.)
EaseInCore Provides the logic portion of the easing function that you can override to produce the EaseIn mode of the custom easing function. (Overrides EasingFunctionBase..::.EaseInCore(Double).)
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetAnimationBaseValue Returns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the Type of the current instance. (Inherited from Object.)
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ReadLocalValue Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
SetValue Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
ToString Returns a string that represents the current object. (Inherited from Object.)

Remarks

You can control whether the animation accelerates, decelerates, or both by specifying the EasingMode. The following graph demonstrates the different values of EasingMode, where f(t) represents the animation progress and t represents time.

The formula used for this function is the following.

f(t) = t3

In addition to using the easing functions included in the run-time, you can create your own custom easing functions by inheriting from EasingFunctionBase.

Examples

The following example applies a CubicEase easing function to a DoubleAnimation to create a decelerating animation.

<StackPanel x:Name="LayoutRoot" Background="Transparent">
    <StackPanel.Resources>
        <Storyboard x:Name="myStoryboard">
            <DoubleAnimation From="0" To="200" Duration="00:00:3" 
                Storyboard.TargetName="myRectangle" 
                Storyboard.TargetProperty="Height">
                <DoubleAnimation.EasingFunction>
                    <CubicEase EasingMode="EaseOut"/>
                </DoubleAnimation.EasingFunction>
            </DoubleAnimation>
        </Storyboard>
    </StackPanel.Resources>

    <Rectangle x:Name="myRectangle" MouseLeftButtonDown="Mouse_Clicked" 
     Fill="Blue" Width="200" Height="30" />

</StackPanel>
' When the user clicks the rectangle, the animation
' begins. 
Private Sub Mouse_Clicked(ByVal sender As Object, ByVal e As MouseEventArgs)
    myStoryboard.Begin()
End Sub
// When the user clicks the rectangle, the animation
// begins. 
private void Mouse_Clicked(object sender, MouseEventArgs e)
{
    myStoryboard.Begin();
}
