Lesson 31 - Animations in C# .NET - Discrete And Spline Keyframes

In the previous lesson, Animations in C# .NET - Storyboard, Basic & Frame Animations, we explained how animations work and learned how to create basic linear animations and linear frame animations.

Discrete Keyframes

If you were careful in math classes, you may have remembered that the word discrete indicates discontinuous values, that is, values that are somehow distant and separate from each other, such as integers and nothing between them.

Discrete keyframes change property values immediately at a specified time without interpolation, i.e. without gradual change, a value just changes to a new one. They're available for all data types that can be animated using keyframes. Classes for discrete keyframes are called Discrete*KeyFrame, such as DiscreteStringKeyFrame.

An Example

This animation isn't suitable for moving a rectangle as in the example above, because the rectangle would only jerk a few times. Therefore, we'll show such an animation instead, where we'll use abrupt changes - we'll write letters to the text of the <Label> element:
