Random Motion
The Random Motion behavior animates the position of an object and makes that object
move around the Canvas along a random path.
Animation path of a
shape affected by the
Random Motion
behavior. The shape of
the path is determined
by the Seed parameter.
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.
You can also use the Random Motion behavior to add variation to the animation paths
created by other behaviors that affect an object’s position. For example, adding Random
Motion to an object with the Orbit Around behavior results in a more erratic animation
path, although it still orbits as before.
