Usage
-- Lingo syntax
castObjRef.fileName
// JavaScript syntax
castObjRef.fileName;
Description
Cast library property; returns or sets the filename of a cast library. Read-only for internal cast
libraries, read/write for external cast libraries.
For external cast libraries,
fileName returns the cast’s full pathname and filename.
For internal cast libraries,
fileName returns a value depending on which internal cast library
is specified.
• If the first internal cast library is specified, fileName returns the name of the movie.
• If any other internal cast library is specified, fileName returns an empty string.
This property accepts URLs as references. However, to use a cast library from the Internet and
minimize download time, use the
downloadNetThing() or preloadNetThing() methods to
download the cast’s file to a local disk, and then set
fileName to the file on the disk.
If a movie sets the filename of an external cast, do no use the Duplicate cast members for Faster
Loading option in the Project Options dialog box.
