Chapter 9 Behaviors 362
In the illustration below, Y and Z are turned on in the Include parameter. The white airplanes
move around the target object in the YZ plane.
•
Pole Axis: A pop-up menu that becomes available when the X, Y, and Z axes are enabled in the
Include parameter. Because all points are at a fixed distance from the target or attractor object
(the Pole Axis), the object can be visualized on a sphere of all possible orbits, with the target
object at the center of the sphere. The Pole Axis defines the two points on the sphere that the
orbit must pass through. There are four menu items:
•
X: Aligns the Pole Axis set to the X plane.
•
Y: Aligns the Pole Axis to the Y plane.
•
Z: Aligns the Pole Axis to the Z plane.
•
Random: When Random is selected, the axes shift to a different random position.
•
Direction: A pop-up menu that sets whether objects move around in a clockwise or
counterclockwise direction.
Random Motion
The Random Motion behavior animates the position of an object and makes that object move
around the Canvas along a random path. The Random Motion behavior is useful for creating
varied animation paths for large numbers of objects you want to move at the same time. For
example, you can create an arrangement of ten objects in the Canvas and apply the Random
Motion behavior to them all.
Although the motion created with this behavior appears to be random, it is predetermined
by the group of parameters you’ve chosen. As long as you don’t change the parameters, the
animation path created by this behavior remains the same. If you don’t like the path that was
randomly generated, click the Generate button in the HUD or the Behaviors Inspector to pick a
new random seed number. This number is used to generate a new path.
