Basic Motion Behaviors
Behaviors are the heart of Motion. In this tutorial, learn
how to use the Basic Motion behaviors to create motion
with just a drag, drop, and a nudge—without creating
keyframes.
Behaviors automatically create motion on an image or object without creating any
keyframes. The motion can be as simple as moving an object across the screen in a
straight line, or as complex as simulated interactions between multiple objects.
Behaviors work by automatically generating a range of values for an object’s
parameters. For example, an object with an applied Spin behavior automatically rotates
the object based on the rate and direction you set.
As another example, an object with an applied Attractor behavior automatically
attracts other objects. The “other” objects can include only objects within the layer to
which the behavior is applied, only objects that you specify, or all objects in the project.
There are five different types of behaviors in Motion: Basic Motion, Simulation,
Parameter, Particle, and Text behaviors, which are among the simplest to use. This
tutorial focuses on the Basic Motion behaviors. These behaviors animate specific
parameters of the object to which they are applied. Some affect position, such as
Throw, while others affect opacity, such as Fade In/Fade Out.
You can adjust the effect of a behavior using simple, graphical controls in the
Dashboard, or dig into all controls for the behavior in the Inspector.
