When you play back your project, the object flies from position one to position two over
the interval you set. You can see the path the object travels by turning on the Animation
Path setting in the View pop-up menu above the Canvas.
Manipulating Animation Paths in the Canvas
You can modify an animation path by adding keyframes to or deleting keyframes from
the path, by dragging keyframes on the path, or by dragging a path segment between
two adjacent keyframes.
Additionally, you can set the keyframe type to curved or angled, changing the shape of
the path.
Note: When you drag a keyframe in the Canvas, the frame number corresponding to that
keyframe and its X, Y, and Z position values are displayed in the status bar (above the
Canvas).
To manipulate an object in the Canvas at a frame where no keyframe exists, use the
following guidelines:
• To reposition the object as well as its bounding keyframes without setting a new
keyframe for the object, drag the object’s center onscreen control (or anywhere on the
object’s animation path).
• To reposition the object and create a new keyframe, drag the object but not its center
onscreen control or animation path.
• To move the object and its entire animation path together, hold down Command-Option
and drag the object’s center onscreen control or any keyframe on the animation path.
To add keyframes to an animation path
µ
Double-click or Option-click the path.
A new keyframe point is added. By default, keyframe points are curved Bezier points.
