Animating graphic objects

On the other hand, you might want to limit the range of values, which
you can also do by specifying minimum and maximum values yourself.
For example, if you specify a minimum of 0 and a maximum of 100,
the object will not react to values outside of this range. So, even if the
expression results to 200, the object does not change from its At
Maximum position.
If an expression uses more than one tag, the first tag in the expression
is used for the minimum and maximum values.
Defining a range of motion
To define a range of motion for an object, do one of the following:
move the objects in the Graphic Display editor. This is called OSP
(Object Smart Path).
type values in the At Minimum and At Maximum fields 2.
All motion is defined in pixels.
Objects that do not have a range of motion
Objects with visibility, color, and touch animation do not have a range
of motion, because these types of animation represent a change of
state, not a range.
Using OSP (Object Smart Path)
With OSP, you can easily set the range of motion for an object. The
following example shows how OSP works.
