Wriggle Offset:
A slider that allows you to offset the sequence of random values when
you want to apply the same Wriggle behavior to multiple objects. By offsetting each
object’s version of the Wriggle behavior, you can prevent objects from moving in sync.
Noisiness:
This slider 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:
This parameter appears when you apply the Wriggle behavior to a two-dimensional
parameter (such as Scale) or three-dimensional parameter (such as Position) that consists
of X, Y, and/or Z values. Turn this checkbox on to keep the behavior’s effect on each value
proportional.
Affect Subobjects:
This parameter only appears when the Wriggle behavior is applied
to a parameter of the Sequence Replicator behavior. When Affect Subobjects is selected,
each object has a different wriggle behavior. When Affect Subobjects is deselected, each
object undergoes the same animation.
Random Seed:
A button that lets you pick a new random seed number. This number is
used to randomly generate new sequences of values, based on the other parameters of
this behavior.
Start Offset:
A slider that lets you delay 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. This parameter is measured in frames.
End Offset:
A slider that lets you offset 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:
The Apply To (Go) pop-up menu shows the parameter being affected and can
be used to reassign the behavior to another parameter.
HUD Controls
The HUD lets you adjust the Amount, Multiplier, Frequency, Wriggle Offset, Noisiness,
Link (for multidimensional parameters), Start Offset, and End Offset parameters, as well
as change the parameter assignment.
