Recording Keyframes 127

Rotating the Cog1 layer clockwise turns the other cogs and opens the curtains. In the

previous lesson, you animated the rotation of this layer using a Rate behavior and

stopped the rotation with a Stop behavior. The result was a rather abrupt ending.

Here, you’ll animate the rotation by recording keyframes.

3 Press Command-Z to undo the rotation, and at the bottom of the Canvas, click the

Record button. The button turns red to let you know that recording is enabled.

4 Press F1 to open the Properties Inspector.

The value fields for all parameters are now red, another warning sign that recording is

enabled. If you change any red parameter, it won’t change for the whole project; it will

change only at the playhead position. Let’s see how this works.
