Random Motion
The Random Motion behavior animates the position of an object and makes that
object move around the Canvas along a random path.
Although the motion created with this behavior appears to be random, it’s actually
predetermined by the particular 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 either the HUD or the Behaviors tab in the Inspector to pick a new random seed
number. This number is used to generate a new path.
The Random Motion behavior is useful for quickly 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 all of them.
Animation path of a shape affected by the
Random Motion behavior. The shape of the
path is determined by the Seed parameter.
