Apple Motion 5.1.1 - Manual (Page 326)

Chapter 9 Behaviors 326
In the next illustration, a Move behavior is added to the airplane shape. The destination point of
the Move path is positioned in the center of the circle. While the airplane circles around (obeying
the Orbit Around behavior), it is also drawn to the center of the target (obeying the Move
behavior), creating a spiraling motion path.
Tip: The Move behavior is useful in 3D mode because it lets you simulate camera movements
without using a camera. For example, when you apply the Move behavior to a group that
contains objects offset in Z space, you can create a dolly-like move.
Parameters in the Inspector
•
Position: Value sliders that allow you to define the X, Y, and Z position of the target point. The
target (the end of the Move path) is placed at the center of the Canvas by default.
Note: You can also drag the target point in the Canvas using the Adjust Item tool.
•
Strength: A slider defining the speed at which the object moves toward the target. With a
value of 0, the object doesn’t move at all. The higher the value, the faster the object moves.
•
Direction: A pop-up menu that sets whether the object moves toward the target point or away
from the point.
•
Speed: A pop-up menu that defines the object’s velocity from its position in the Canvas to the
position of the target. There are six choices:
•
Constant: The object moves at a steady speed from its position toward the target.
•
Ease In: The object starts at a slow speed, then reaches and maintains a steady speed toward
the target.
•
Ease Out: The object starts at a steady speed, then gradually decelerates to a stop when it
reaches the target.
•
Ease Both: The object slowly accelerates, then decelerates to a stop when it reaches
the target.
•
Accelerate: The object moves toward the target with increasing speed.
•
Decelerate: The object moves toward the target with decreasing speed.
Note: To move the object more slowly toward its target, extend the duration of the Move To
behavior in the Timeline or mini-Timeline. To move the object faster, shorten the duration of
the behavior.
Point At
The Point At behavior causes an object or group to turn toward a target point. Use the Point At
behavior with the Move To behavior to created animated objects that not only move toward a
point (or each other), but that turn in the direction of the target.
