Chapter 9 Behaviors 347
•
Noisiness: A slider that adds an additional overlay of random variance to the Frequency you’ve
set. Higher Noisiness values result in more erratic variations in the affected parameter.
•
Link: A checkbox, available when you apply Randomize to a two-dimensional parameter (such
as Scale) or three-dimensional parameter (such as Position) that consists of X, Y, and/or Z
values. Select this checkbox to keep the behavior’s effect on each value proportional.
•
Affect Subobjects: A checkbox, available when you apply Randomize to a parameter of
the Sequence Replicator behavior. When Affect Subobjects is selected, each object has a
different random behavior. When Affect Subobjects is deselected, each object undergoes the
same animation.
•
Random Seed: A button that picks a new random seed number. This number is used to
generate new sequences of values, based on the other parameters of this behavior.
•
Start Offset: A slider that delays the beginning of the behavior’s effect relative to the first frame
of its position in the Timeline. Adjust this parameter to make the behavior start later. The units
of this parameter are in frames.
•
End Offset: A slider that offsets the end of the behavior’s effect relative to the last frame of its
position in the Timeline, in frames. Adjust this parameter to make the behavior stop before
the actual end of the behavior in the Timeline. Using this slider to stop the effect, instead of
trimming the end of the behavior in the Timeline, freezes the last random value generated
by this behavior for the remaining duration of the object. Trimming the end of the behavior
resets the parameter to its original value.
•
Apply To: A pop-up menu shows the parameter affected and can be used to reassign the
behavior to another parameter.
Rate
The Rate behavior increases a parameter’s value over time, with the rate of increase determined
by the Rate slider. Unlike the Ramp behavior, this behavior has no end value, but continues to
increase or decrease the parameter it’s applied to until the end of the parameter.
Note: To decrease a parameter over time, enter a negative value into the Rate parameter.
Parameters in the Inspector
•
Rate: A slider that sets a rate of increase over time for the affected parameter. Measured in
percentage increase per second.
•
Curvature: A slider that eases the acceleration at which the Rate behavior transitions from
the Start Value to the End Value. Higher Curvature values result in an ease in/ease out effect,
beginning slowly, gradually speeding up as the behavior continues, then gradually slowing to
a stop as it reaches the end. Because Curvature is defined by the length of the behavior in the
Timeline, this parameter does not affect the overall duration of the effect.
•
End Offset: A slider that offsets the end of the behavior’s effect relative to the last frame of its
position in the Timeline, in frames. Adjust this parameter to make the behavior stop before
the actual end of the behavior in the Timeline. Using this slider to stop the effect, instead of
trimming the end of the behavior in the Timeline, freezes the last random value generated
by this behavior for the remaining duration of the object. Trimming the end of the behavior
resets the parameter to its original value.
•
Apply To: A pop-up menu that shows the parameter affected and can be used to reassign the
behavior to another parameter.
