Note: The Zoom slider controls the magnification of the Throw control. So if you drag
the arrow to be as large as it can be and the object is still not moving fast enough, you
can increase the Zoom amount to give the Throw control more range.
Creating Motion With Keyframes
Behaviors provide one quick and easy way to create movement in the Canvas.
Keyframes provide another (although, not so quick). Think of behaviors as applying a
rate of change to the parameters of an object over the duration of that object. In turn,
think of keyframes as setting specific values for the parameters of an object at specific
points in time.
To animate an object using keyframes:
1 Press Home to return to the first frame of the project.
2 Enable Record (click the Record button, or press A).
The Record button pulses red.
When Record is enabled, any changes you make to the parameters of an object are
applied at the current playhead position. This is called keyframing. If you set two
different values at two different points in time, Motion animates the values of the in-
between frames.
3 Position the GreenSquares object (layer) so the rightmost box is out of the visible area
of the Canvas.
4 Press End to go to the last frame of the project.
5 Drag the GreenSquares object to the left until the leftmost square lines up with the left
edge of the Canvas.
