The left image below shows the projected path (the red line) of a layer with an applied Throw
behavior. The right image displays the same animation path after the Quantize behavior is
added. In this example, the Step value is set to 90.
•
Oset: A slider that osets the steps. For example, when Quantize is applied to a Position
parameter and Step Size is set to 100, an object “steps” in increments restricted to 100 pixels;
thus, the step oset is 100, 200, 300, and so on. If Oset is set to 50, the step oset is restricted
to 50, 150, 250, and so on.
•
Apply To: A pop-up menu that shows the parameter aected, and can be used to reassign the
behavior to another parameter.
Ramp
The Ramp behavior creates a gradual transition in any parameter that can be animated, from
the Start Value to the End Value. The speed of the transition is dened by the length of the
Ramp behavior in the Timeline, and by the behavior’s end value. Additional parameters allow
you to dene how the transition occurs, whether it’s at a single continuous speed, or whether it
accelerates over time.
Ramp is a versatile behavior. If you apply it to the Scale property, it works like the Grow/Shrink
behavior. If you apply it to the Opacity property, you can fade an object in or out in dierent
ways. Although you can use the Ramp behavior to mimic other Motion behaviors, it can be
applied to any parameter. It is an additive behavior, meaning that the value it generates is added
to the original value of the parameter to which it’s applied.
For example, to animate dierent segments of a bar graph so each segment grows to a specic
length, apply the Ramp behavior to the each bar’s Crop parameter. After you arrange the
dierent bars with their starting Crop values, the Ramp behaviors move the Top Crop parameter
up, giving the illusion that each bar is growing. Set the End Value parameter of each Ramp
behavior to the length you want each bar to reach, and you’re done!
