9. Hide the properties for the Falling Star layer.Animating fill color
Currently, the star remains yellow with a red stroke as it becomes a flower. You’ll animate its fill
color so that the final flower is red.
1. Press the Home key or move the current-time indicator to the beginning of the time ruler.
2. Expand the Falling Star layer, and then expand the Contents, Polystar 1, and Fill 1
properties.
3. Click the stopwatch ( ) next to the Color property to create an initial keyframe.
4. Go to 4:01, and change the fill color to a red color. (We used R=192, G=49, B=33.)5. Hide all layer properties. Press F2 or click an empty area in the Timeline panel to deselect
all layers.
6. Press the spacebar to preview your animation. Press the spacebar again to stop playback.
7. Choose File > Save.Creating nulls from paths
When you parent one layer to another, the child layer adopts the parent layer’s attributes. But it’s
a bit trickier when you want to create a relationship between a single point on a shape and
another layer. The Create Nulls From Paths panel makes it easier to do just that. A null object is
an invisible layer that has all the same properties as other layers so that it can serve as a parent to
any layer. The Create Nulls From Paths panel creates null objects based on specific points, which
you can then parent to other layers without having to write complex expressions.
Note
The Create Nulls From Paths panel works only with masks or with Bezier shapes
(shapes drawn with the Pen tool). To convert a shape drawn with a shape tool to a
Bezier path, expand the shape layer contents, right-click the path (e.g., Rectangle 1),
and choose Convert To Bezier Path.
