End Offset:
A slider that lets you offset the end of the behavior’s effect relative to the
last frame of its position in the Timeline, in frames. Adjust this parameter to make the
behavior stop before the actual end of the behavior in the Timeline. Use this slider to
offset the end of the Grow/Shrink effect from the end of the object.
HUD Controls
The Grow/Shrink HUD consists of two rectangular regions. The first, a rectangle with a
dotted line, represents the original size of the object. The second is a solid rectangle that
represents the relative growth rate, and can be resized by dragging any of the borders.
Enlarge the box to grow the target object, or reduce the box to shrink it. A slider to the
right lets you adjust the scale of the HUD controls, increasing or decreasing the effect
the controls have over the object.

Motion Path
The Motion Path behavior lets you create a 2D or 3D motion path for an object to follow.
When you first apply the Motion Path behavior, it defaults to an open spline—a straight
line defined by two points at the beginning and end of the motion path. You can also
choose from preset path shapes, such as a closed spline, loop, rectangle, or wave, or use
a shape to define a path. A shape used as the source for a motion path can be animated.
You can modify the motion path in 3D space so that an object travels on the path along
the path’s X, Y, and Z axes. For more information, see
