4. In the 3D view tools (in the upper-right corner of the canvas), drag in the Orbit tool (the
center tool).
As the camera rotates, you can see that the replicator cells are aligned in Z space.
Tip: Use Simulation behaviors to create animated replicators in 3D space that interact
with other objects in the project. For example, use Orbit Around to make replicator
elements circle around a target object. See Intro to Simulation behaviors in Motion.
Make replicators interact with other objects
When a replicator is a member of a 3D group, certain behaviors can be applied to pull
replicator pattern elements out of their X and Y planes.
1. After adding a replicator to a Motion project, select the 3D checkbox in the Replicator
Inspector.
This example uses a burst replicator shape. For more information on adding a replicator
to a project, see Add a replicator in Motion.
2. If your project does not contain a camera, click Add Object in the toolbar, choose
Camera, then click Switch to 3D.
A camera is added to the project, and your layers are turned into 3D layers.
3. In the Layers list, select an object (a white circle shape in this example), and in the
Properties Inspector, click the Position disclosure triangle, then drag in the Z value slider.
In this example, the white circle’s Z Position is set to 225.
4. In the Layers list, select the replicator, click Behaviors in the toolbar, then choose
Simulations > Attracted To.
No animation occurs until an object is assigned to the Attracted To behavior.
5. With the Attracted To behavior selected in the Layers list, drag the target object (in this
example, the white circle) to the Object well in the Behaviors Inspector.
With the default Attracted To settings, the entire replicator pattern moves (as a single
unit) toward the target object.
6. In the Behaviors Inspector, select the Affect Subobjects checkbox.
7. To play the project, press the Space bar.
As the project plays, each replicator element moves individually forward in Z space,
toward the attractor. Under the behavior’s influence, the replicator elements move past
their attractor element, then return to their original position.
