• Influence: A slider that defines the radius of the circle of influence, in pixels. Objects
that fall within the area of influence move toward the object of attraction. Objects
outside the area of influence remain in place.
• Drag: A slider that reduces the distance attracted objects overshoot the object of
attraction. Lower Drag values result in the object overshooting the object of attraction,
moving past and then careening back around toward the target object again and again.
Higher Drag values result in the object coming to rest sooner.
• Include X, Y, and Z: Buttons that specify the axes on which the affected object (or
objects) moves around the object to which it is attracted. When Z is enabled, the object
moves about its attractor object in Z space.
Attractor behavior in Motion
The Attractor behavior, when applied to an object, causes other objects that lie within
the area of influence to move toward it. You can manipulate the strength with which other
objects are attracted, as well as the distance required for attraction to begin.
By default, objects overshoot the object of attraction and bounce around, never coming to
rest. The Drag parameter lets you adjust this behavior, changing whether attracted objects
overshoot and bounce around, or whether they eventually slow down and stop at the
position of the target object.
The Attractor behavior can affect all objects in the canvas that fall within the area of
attraction, or you can limit its effect to a specific list of objects by using the Affect
parameter.
The Attractor behavior can also be applied to objects in motion. If you animate the position
of the target object to which you’ve applied the Attractor behavior, all other objects in the
canvas continue to be attracted to its new position.
Adjust this behavior using the controls in the Behaviors Inspector:
• Affect: A pop-up menu that limits which objects in your project are affected by the
Attractor behavior. There are three options:
• All Objects: All objects in the canvas are affected by the Attractor behavior.
• Related Objects: The default setting. Only other objects in the same group as the
object of attraction are affected.
• Specific Objects: Only objects appearing in the Affected Objects list are affected by
the Attractor behavior.
