Looping behaviors
Looping behaviors make the playhead return (loop) to a frame or stay on the current frame until
specified media elements have been downloaded and then continue to the next frame. Attach a
looping behavior to a frame in the script channel, not to a sprite. The following looping behaviors
are accessible by selecting Internet > Streaming from the Library List menu in the Library palette:
Loop until Next Frame is Available
loops the playhead to a specified frame until all the media
elements that are required for the next frame have been downloaded.
Loop until Member is Available
loops the playhead to a specified frame until a certain cast member
has been downloaded.
Loop until Media at Marker is Available
loops the playhead to a specified frame until all the media
elements for the frame at the specified marker have been downloaded.
Loop until Media in Frame is Available
loops the playhead to a specified frame until all the media
elements that are required for a certain frame have been downloaded.
Jumping behaviors
Jumping behaviors make the playhead skip to a specified frame or marker after certain media
elements have been downloaded. Attach a jumping behavior to a frame in the script channel,
not to a sprite.
Jump When Member is Available
moves the playhead to the specified frame after a certain cast
member has been downloaded.
Jump When Media in Frame is Available
moves the playhead to the specified frame after the media
elements for a particular frame have been downloaded.
Jump When Media in Marker is Available
moves the playhead to the specified frame after the media
elements for the frame at a particular marker have been downloaded.
Checking whether media elements are loaded with Lingo
Director has several options that let an initial portion of a movie start playing as soon as the required
data and cast members are available. You can use Lingo to check whether media elements have been
downloaded from a network by testing the following:
•
Whether a specific cast member is loaded before the movie proceeds
•
Whether the cast members used in a specific frame are loaded before the frame plays
Checking whether a cast member or sprite is loaded
To determine whether a specified cast member is available locally, you use the
mediaReady
cast
member or sprite property. You can check for a specific cast member or the cast member that is
assigned to a specific sprite. When
mediaReady
returns
TRUE
, the cast member is available. See
mediaReady
in the Lingo Dictionary.
This property always returns
TRUE
for local files. It is useful only for movies that stream from a
remote server. Because playback can begin before the entire movie has been downloaded, you must
make sure that necessary media elements have been downloaded as the movie plays.
