317Motion User Guide
• 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 behavior in Motion
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 create animated objects that not only move
toward a point (or each other), but that turn in the direction of the target.
Adjust this behavior using the controls in the Behaviors Inspector:
• Object: An object well that defines the target object. To set the target object, drag an
object from the Layers list to this object well. You can also drag the target object from
the Layers list onto the Point At behavior.
• Transition: A slider that determines how long it takes the object to go from its starting
orientation to pointing at the center of the target object. This parameter is useful when
the object is pointing at a moving target object.
If Transition is set to 50% in a 300-frame project, and the target object is not moving,
the point-at object takes 150 frames to point at (or orient to) the center of the target
object and then stops moving for the duration of the behavior. If Transition is set to
100%, the point-at object takes the full 300 frames to point at the target object. If the
Point At behavior’s duration is 100 frames, and Transition is set to 50%, the point-at
object takes 50 frames to orient to the target object.
If Transition is set to 50% in a 300-frame project, and the target object is animated, the
point-at object takes 150 frames to point at (or orient to) the center of the target object
and then continues following the animated target object for the duration of the behavior.
If Transition is set to 100%, the point-at object takes the full 300 frames to point at the
target object.
• 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 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.
