# How to: Animate an Object Along a Path (Point Animation)
|
|
This example shows how to use a <xref:System.Windows.Media.Animation.PointAnimationUsingPath> object to animate a <xref:System.Windows.Point> along a curved path.
|
|
|
|
## Example
|
|
The following example moves an <xref:System.Windows.Media.EllipseGeometry> along a path defined by a <xref:System.Windows.Media.PathGeometry>. The ellipse geometry's <xref:System.Windows.Media.EllipseGeometry.Center%2A> property, which takes a <xref:System.Windows.Point> value, specifies its position; to move the ellipse geometry, you animate its <xref:System.Windows.Media.EllipseGeometry.Center%2A> property. The example uses a <xref:System.Windows.Media.Animation.PointAnimationUsingPath> to animate the <xref:System.Windows.Media.EllipseGeometry> object's <xref:System.Windows.Media.EllipseGeometry.Center%2A> property.

For the complete sample, see [Path Animation Sample](https://github.com/Microsoft/WPF-Samples/tree/master/Animation/PathAnimations).
|
|
|
|
The code version of the preceding sample used a <xref:System.Windows.Media.Animation.Storyboard> to animate the <xref:System.Windows.Media.EllipseGeometry>, even though only one animation was applied. A <xref:System.Windows.Media.Animation.Storyboard> is often the easiest way to apply multiple animations because these animations can be controlled by the same <xref:System.Windows.Media.Animation.Storyboard>. However, an easier way to apply a single animation to a property when using code is to use the <xref:System.Windows.Media.Animation.Animatable.BeginAnimation%2A> method. For an example, see [Animate a Property Without Using a Storyboard](how-to-animate-a-property-without-using-a-storyboard.md).
