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:
