Chapter 9 Behaviors 365
•
Fallo Rate: A slider that sets how quickly the force of repulsion between objects aected by
this behavior falls o. A low Fallo Rate value results in objects quickly getting up to speed as
they move away from the object of repulsion. A high Fallo Rate causes objects to accelerate
much more slowly. When set to Exponential, the attraction falls o more quickly than when set
to Linear.
•
Inuence: A slider that denes the radius of the circle of inuence in pixels. Objects that fall
within the area of inuence move away from the object of repulsion. Objects outside the area
of inuence 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 eect, making the object it’s applied to move away from a selected object in
the Canvas.
Parameters in the Inspector
•
Aect 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 aected individually. When this
checkbox is deselected, all objects in the parent object are aected by the behavior together.
•
Object: An object well that denes 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.
•
Fallo Type: A pop-up menu that determines whether the distance dened by the Inuence
parameter falls o linearly or exponentially.
•
Linear: Repulsion between objects falls o in proportion to the object’s distance.
•
Exponential: The closer an object is within the area of inuence, the more strongly it is
repelled, and the faster it moves away from the object doing the repelling.
•
Fallo Rate: A slider that sets how quickly the force of repulsion between objects aected by
this behavior falls o. A low Fallo Rate value results in objects quickly getting up to speed as
they move away from the object of repulsion. A high Fallo Rate causes objects to accelerate
much more slowly. When set to Exponential, the attraction falls o more quickly than when set
to Linear.
•
Inuence: A slider that denes the radius of the circle of inuence in pixels. Objects that fall
within the area of inuence move away from the object of repulsion. Objects outside the area
of inuence 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.
