Apple Motion 4 - Manual (Page 506)

Bounce Strength: The speed at which objects travel after colliding with an edge. A value
of 0 causes objects to come to a complete stop when colliding with an edge that’s
perpendicular to the direction of motion. Higher values cause an object to move faster
after bouncing. This parameter only slows the object in the direction perpendicular to
the bounced edge.
Active Edges: Six checkboxes define which collision box edges are detected by the Edge
Collision behavior. You can turn edges on and off in any combination.
• Left Face: Defines the left edge for the collision.
• Right Face: Defines the right edge for the collision.
• Top Face: Defines the top edge for the collision.
• Bottom Face: Defines the bottom edge for the collision.
• Back Face: Defines the back edge (in Z space) for the collision.
• Front Face: Defines the front edge (in Z space) for the collision.
Width: A slider that allows you to define a width (the right and left edges of the Canvas)
other than the size of project. By default, Width is set to the project size.
Height: A slider that allows you to define a height (the top and bottom edges) other
than the size of project. By default, Height is set to the project size.
Depth: A slider that allows you to define a depth (the back and front faces, in Z space)
for the edge collision. By default, Depth is set to 100 pixels.
HUD Controls
The HUD has controls for Bounce Strength and Width, Height, and Depth. When applied
to an object that contains multiple objects (such as a group, particles, text, or the
replicator), the Affect Subobjects checkbox also appears in the HUD.
