Set up visibility animation

Use the
Visibility
tab to attach visibility animation to a graphic object.
TIP:
If a group object and the objects within a group object have visibility animation set up, and the group's visibility is set to
False
, no objects within the group will be visible even if their individual visibility is set to
True
.
If the group's visibility is set to
True
, objects within the group that have their individual animation set to
False
will not be visible.
Be sure to test group animation to ensure that it produces the effect you intend.
To set up visibility animation:
  1. In the
    Visibility
     tab, in the
    Expression
     field, type a tag name or an expression that will evaluate to
    True
    or
    False
    at runtime. You can also click
    Tag
     to browse for a tag, or click
    Expression
     to open the
    Expression Editor
     to create one.
  2. Under
    Expression true state
    , select
    Invisible
     or
    Visible
     to specify the object's state when the expression returns
    True
     (a non-zero value).
    TIP:
    If you use a tag's value to control visibility animation as well as in an expression to control some other aspect of animation, when you set up visibility you should set the
    Expression true state
     to
    Invisible
    . If you do not do this, the object could appear briefly in its design-time location and orientation before animating properly.
