14.12. Simple Animation
Silverlight allows you to animate objects both declaratively and programmatically. Animation is perhaps easier to understand programmatically, so you will create a very simple animation to move a rectangle across a screen and at the same time change its transparency by modifying its opacity.
You will use a Storyboard class to create an animation. The Storyboard defines what will happen within the animation (the story) and contains features to start, stop, and repeat the animation.
The storyboard has a property called Interval that is a timer that allows you to perform the animation. In the example when the storyboard interval occurs, you will increment the x and y positions of the rectangle and increase the opacity.
