Parameters in the Inspector
Rate:
A value slider that lets you set a rate of increase over time for the affected parameter.
Measured in percentage increase per second.
Curvature:
This parameter lets you ease the acceleration with which the Rate behavior
transitions from the Start Value to the End Value. Higher Curvature values result in an
ease in/ease out effect, where the value slowly begins the transition, gradually speeds
up as the behavior continues, then gradually slows down to a stop as it reaches the end.
Curvature does not affect the overall duration of the effect, since that is defined by the
length of the behavior in the Timeline.
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 has controls for Rate, Curvature, and parameter assignment.

Reverse
Unlike the Negate behavior, which inverts the value of the parameter to which it’s applied,
the Reverse behavior reverses the direction of any animation that affects a parameter,
whether it’s caused by behaviors or keyframes. For example, when you apply the Reverse
behavior to path animation that begins at the left and moves to the right, the animation
path won’t move, but the object instead begins at the right and moves to the left. The
Reverse behavior basically switches the beginning and ending points of animated objects.
