Represents an easing function that creates an animated bouncing effect.
The BounceEase class has these types of members:
The BounceEase class has these constructors.
|BounceEase||Initializes a new instance of the BounceEase class.|
The BounceEase class has these methods. It also inherits methods from the Object class.
|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)|
|GetAnimationBaseValue||Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)|
|GetValue||Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)|
|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)|
The BounceEase class has these properties.
|Read/write||Gets or sets the number of bounces.|
|Read-only||Identifies the Bounces dependency property.|
|Read/write||Gets or sets a value that specifies how bouncy the bounce animation is. Low values of this property result in bounces with little loss of height between bounces (more bouncy) while high values result in dampened bounces (less bouncy).|
|Read-only||Identifies the Bounciness dependency property.|
|Read-only||Gets the CoreDispatcher that this object is associated with. (Inherited from DependencyObject)|
|Read/write||Gets or sets a value that specifies how the animation interpolates. (Inherited from EasingFunctionBase)|
ElasticEase is a similar easing function that works well for physics emulation in animations. The difference with BounceEase is that an ElasticEase can go outside the From/To range. Another way to conceptualize the two easing functions is that ElasticEase is what you might use to animate the plucking of a string, whereas BounceEase is what you might use to show the bounce of a ball against a line or plane.
An easing function can be applied to the EasingFunction properties of From/To/By animations, or to the EasingFunction properties of key-frame types used for the Easing variants of key-frame animations. For more info, see Key-frame animations and easing function animations.
The following example applies a BounceEase easing function to a DoubleAnimation to create a bouncing effect.
