Parameters in the Inspector
Amount/Multiplier: This parameter is set to Amount when the Apply Mode is set to Add,
Subtract, or Add and Subtract; it is set to Multiplier when the Apply Mode is set to Multiply.
This parameter defines the maximum value the Randomize behavior will generate.
Apply To: A pop-up menu that defines whether the behavior is applied to the shape’s
control points, tangent handles, or both points and handles.
• Points: The control points of the shape are randomized, changing their position over
the duration of the behavior.
• Tangents: The control points’ tangent handles (rather than the control points) of the
shape are randomized. The control points stay in a fixed position while the curves
between the points are animated.
• Points and Tangents: Both the control points and handles are animated.
Apply Mode: A pop-up menu that determines how values generated by this behavior
are combined with other behaviors and keyframes that affect the same parameter. This
provides you with different ways of using a Randomize behavior to modify a vertex’s
preexisting values. There are four options:
• Add: Values generated by this behavior are added to other behaviors and keyframes
that affect the same parameter.
• Subtract: Values generated by this behavior are subtracted from other behaviors and
keyframes that affect the same parameter.
• Multiply: Values generated by this behavior are multiplied by other behaviors and
keyframes that affect the same parameter.
• Add and Subtract: Values generated by this behavior are added to and subtracted from
other behaviors and keyframes that affect the same parameter.
Frequency: A slider that lets you adjust the amount of random variation per second.
Higher values generate faster variations, whereas lower values generate slower variations.
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: This parameter appears when you apply this behavior to a two-dimensional
parameter (such as Distort) or three-dimensional parameter (such as Position or Rotation)
that consists of X, Y, and/or Z values. Select this checkbox if you want the transformation
applied to the X and Y vertices to be the same. For instance a +10 change to X will result
in an identical +10 change to Y.
Preserve Angle: When this checkbox is selected, the tangent handles become (or remain)
flat, maintaining the continuity of the curves.
