Note: Although the Spin behavior appears in the Basic Motion category, Spin is treated as a
Simulation behavior in Motion’s order of operations. For more information, see
Behavior order of
operations on page 306.
Parameters in the Inspector
•
Affect Subobjects: A checkbox, available when Spin is applied to an object that contains
multiple objects (such as a group, particle emitter, or text), that causes each object in the layer
or group to rotate as an individual object. When this checkbox is deselected, the entire layer or
group spins uniformly.
•
Increment: A pop-up menu that sets how the behavior’s effect progresses over its duration in
the Timeline. There are two choices:
•
Continuous Rate: Uses the Spin Rate parameter to spin the object by a steady number of
degrees per second.
•
Ramp to Final Value: 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. When Increment is set
to Continuous Rate, Spin Rate defines a continuous rate of spin in degrees per second. When
Increment is set to Ramp to Final Value, 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
counterclockwise motion.
•
Axis: A pop-up menu that sets whether the object spins about the X, Y, or Z axis. You can also
choose Custom, which yields additional Longitude and Latitude parameters. The following
illustration shows the Spin behavior’s HUD control set to the Z axis.
When Axis is set to Custom, additional Longitude and Latitude parameters become available.
These parameters allow the object to spin at an angle (not locked to the X, Y, or Z axes).
