Parameters in the Inspector
Increment: This pop-up menu lets you choose how the behavior’s effect progresses
over its duration in the Timeline. There are two options:
• Continuous Rate: This command uses the Scale Rate parameter to grow or shrink
the object by a steady number of pixels per second.
• Ramp to Final Value: This command grows or shrinks the object from its original
size to the specified percentage plus the original scale in the Scale To parameter. If
the behavior is shortened in the Timeline, the Grow/Shrink effect goes faster.
Scale Rate/Scale To: Depending on the command chosen in the Increment pop-up
menu, the Scale Rate or Scale To parameter defines the speed and magnitude of the
effect. This parameter can be opened into X and Y subparameters by clicking the
disclosure triangle to the left. This lets you adjust the horizontal or vertical scale
independently.
Curvature: This parameter lets you adjust the acceleration with which this behavior
transitions from the original to the final size. Higher Curvature values result in an easing
into and out of the effect, where the object slowly starts to change size, and this
change gradually speeds up as the behavior continues. Curvature does not affect the
overall duration of the effect since that is defined by the length of the behavior in the
Timeline, minus the End Offset.
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. Use this slider to
offset the end of the Grow/Shrink effect from the end of the object.
