• 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 list to the Object well in the Point At HUD or Inspector. You can
also drag the target object from the Layers list onto the Point At behavior.
Transition: This slider determines how long it takes for 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.
