Note: You can spin the arrow around the ring multiple times to rotate the object faster.
Parameters in the Inspector
Affect Objects: This parameter appears when Spin is applied to a layer or object (such
as a particle emitter or text) that contains multiple objects. When this checkbox is
turned on (default), each object within the parent object rotates as an individual
object. When this checkbox is turned off, the entire layer or object spins.
Increment: This pop-up menu lets you choose how the behavior’s effect progresses
over its duration in the Timeline. There are two choices:
• Continuous Rate: This command uses the Spin Rate parameter to spin the object by
a steady number of degrees per second.
• Ramp to Final Value: This command spins the object for the number of degrees
specified in the Spin To parameter over the behavior’s duration in the Timeline.
Spin Rate/Spin To: A dial controlling the speed at which the object spins. The Spin
Rate defines a continuous rate of spin in degrees per second. Spin To defines a number
of degrees to spin over that object’s duration. Negative values result in clockwise
motion, while positive values result in counter-clockwise motion.
Throw
The Throw behavior is the simplest way of setting an object in motion. Controls let you
adjust the speed and direction of a single force that’s exerted on the object at the first
frame of the behavior. After this initial force is applied, the object continues drifting in a
straight line at the same speed, for the duration of the Throw behavior.
A simple example of using the Throw behavior is to send a series of offscreen text
objects moving across the screen. When used in conjunction with other behaviors such
as Grow/Shrink and Fade In/Fade Out, you can create sophisticated moving titles
without keyframing a single parameter.
