Apple Motion 3 - Manual (Page 677)

Chapter 7 Using Text 677
To create a text animation using non-text behaviors:
1 From the Basic Motion subcategory, apply the Throw behavior to the text.
2 Adjust the Throw so that the text moves across the Canvas.
3 From the Simulations subcategory, apply the Edge Collision and Vortex behaviors to
the text.
4 In the Inspector, turn on the Affect Subobjects checkbox for the Edge Collision
behavior.
5 Play the project (press the Space bar).
The text characters are swept around the screen in a vortex pattern. If the text
characters start to move off the screen, they collide with the edge of the screen.
Related Objects is the default setting in the Affect parameter of the Vortex behavior,
which means that all objects within the same group are affected. You can change this
to Specific Objects to select which layers are affected, or change it to All Objects.
