Apple Motion 4 - Manual (Page 452)

Note: The Move behavior and the Adjust Item tool in the Toolbar must be selected to
move the target. Use the Select/Transform tool to move the object.
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 slows down as it gradually decelerates
to a stop when it reaches the target.
• Ease Both: The object slowly accelerates and then slows down as it gradually 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.
HUD Controls
The HUD has a slider that sets the influence amount (Strength), a Direction pop-up menu
that defines whether the object moves toward the null point or away from the point, and
a Speed pop-up menu that allows you to define the object’s velocity.
Point At
When the Point At behavior is applied to an object or group, you can specify a target
point for the affected object to turn toward.
Tip: Use the Point To 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.
Parameters in the Inspector
Object: An image well that defines the target object. To set the target object, drag the
object from the Layers tab to the Object well in the Point At HUD or Inspector. You can
also drag the target object from the Layers tab onto the Point At behavior.
