Name

Availability

Synopsis
_root
Access
Read-only
Description
The _root property stores a reference to the main
timeline of the current document level. We use
_root to invoke methods on the main movie or to
retrieve and set the main movie’s properties. For example:
_root.play( ); // Play the main timeline _root._alpha = 40; // Make the whole movie partially transparent
The _root property may also be used to refer to
nested clips. For example:
_root.myClip.play( ); _root.shapes.square._visible = false;
The _root property provides access to a movie clip
in absolute terms. That is, a reference that starts with
_root is valid (and invariant) from anywhere in a
movie.
