•
Damping: A slider, available when Wave is the defined path shape, that progressively
diminishes the oscillation of the wave. Positive values diminish the wave forward (from left
to right); negative values diminish the wave backward (from right to left). The following
illustration shows positive damping applied to the wave motion path.
•
Attach to Shape: When Geometry is the defined path shape, this checkbox, when activated,
forces the motion path to follow the source shape at its original location. When disabled, the
motion path can exist in a location other than its source shape.
Note: When Attach to Shape is on, you cannot move the object to another location.
Tip: To align the rotation of an object to match all changes made to its position along an
animation path, apply the Snap Alignment to Motion behavior. For more information, see
on page 327.
•
Shape Source: An object well, available when Geometry is the defined path shape, that
specifies the object (a shape or mask) used as the motion path source. Choose an available
shape from the adjacent “To” pop-up menu, or drag a shape from the Layers list into the
object well.
•
Direction: A pop-up menu that defines the object’s direction along the path. There are two
options:
•
Forward: The object moves in a forward direction along the path (from the start point to the
end point, depending upon the Offset parameter).
•
Reverse: The object moves in a backward direction along the path (from the end point to the
start point, depending upon the Offset parameter).
Note: The Offset parameter is available when Path Shape is set to Circle or Rectangle.
•
Speed: A pop-up menu that defines the object’s velocity from the first to the last point in the
motion path. There are eight choices:
•
Constant: The object moves at a steady speed from the first to the last point on the
motion path.
•
Ease In: The object starts at a slow speed, then reaches and maintains a steady speed
through the last point on the motion path.
•
Ease Out: The object starts at a steady speed, then slows down as it gradually decelerates to
a stop at the last point of the motion path.
•
Ease Both: The object slowly accelerates from the first point on the motion path, then slows
down as it gradually decelerates to a stop at the last point of the motion path.
•
Accelerate: The object moves along the path with increasing speed.
•
Decelerate: The object moves along the path with decreasing speed.
