Chapter 9 Behaviors 365
•
Falloff Rate: A slider that sets how quickly the force of repulsion between objects affected by
this behavior falls off. A low Falloff Rate value results in objects quickly getting up to speed as
they move away from the object of repulsion. A high Falloff Rate causes objects to accelerate
much more slowly. When set to Exponential, the attraction falls off more quickly than when set
to Linear.
•
Influence: A slider that defines the radius of the circle of influence in pixels. Objects that fall
within the area of influence move away from the object of repulsion. Objects outside the area
of influence remain in place.
•
Drag: A slider that reduces the distance repelled objects travel away from the repelling object.
•
Include X, Y, and Z: Buttons that specify the space in which the objects move away from the
object with the applied Repel behavior. For example, when X and Y are enabled, the object
moves away in the XY plane; when Y and Z are enabled, the object moves away in the
YZ plane.
Repel From
Whereas the Repel behavior pushes other objects away, the Repel From behavior has the
converse effect, making the object it’s applied to move away from a selected object in
the Canvas.
Parameters in the Inspector
•
Affect Subobjects: A checkbox that appears when this behavior is applied to an object that
contains multiple objects, such as a group, a particle emitter, a replicator, or a text layer. When
this checkbox is selected, all objects in the parent object are affected individually. When this
checkbox is deselected, all objects in the parent object are affected by the behavior together.
•
Object: An object well that defines the object to be repelled from.
•
Strength: A slider that sets the speed at which the object is repelled. With a value of 0, the
object is not repelled at all. The higher the value, the faster the object is repelled.
•
Falloff Type: A pop-up menu that determines whether the distance defined by the Influence
parameter falls off linearly or exponentially.
•
Linear: Repulsion between objects falls off in proportion to the object’s distance.
•
Exponential: The closer an object is within the area of influence, the more strongly it is
repelled, and the faster it moves away from the object doing the repelling.
•
Falloff Rate: A slider that sets how quickly the force of repulsion between objects affected by
this behavior falls off. A low Falloff Rate value results in objects quickly getting up to speed as
they move away from the object of repulsion. A high Falloff Rate causes objects to accelerate
much more slowly. When set to Exponential, the attraction falls off more quickly than when set
to Linear.
•
Influence: A slider that defines the radius of the circle of influence in pixels. Objects that fall
within the area of influence move away from the object of repulsion. Objects outside the area
of influence remain in place.
•
Drag: A slider used to reduce the distance the object or objects travel away from the
repelling object.
•
Include X, Y, and Z: Buttons that specify the space in which the object moves away from the
selected object. For example, when X and Y are enabled, the object moves in the XY plane;
when Y and Z are enabled, the object moves in the YZ plane.
