Usage
-- Lingo syntax
memberOrSpriteObjRef .isVRMovie
// JavaScript syntax
memberOrSpriteObjRef .isVRMovie;
Description
QuickTime cast member and sprite property; indicates whether a cast member or sprite is a
QuickTime VR movie that has not yet been downloaded (
TRUE
), or whether the cast member or
sprite isn’t a QuickTime VR movie (
FALSE
).
Testing for this property in anything other than an asset whose type is #quickTimeMedia
produces an error message.
This property can be tested but not set.
Example
The following handler checks to see if the member of a sprite is a QuickTime movie. If it is, the
handler further checks to see if it is a QTVR movie. An alert is posted in any case.
