In both Director projectors and in Shockwave movies, the QT3 Asset Xtra handles QuickTime 3 media the same way Director currently handles digital video. You can link the QuickTime 3 media to a URL, and the projector or the Shockwave movie begins to download the QuickTime 3 media when its sprite first appears on the stage.
When using QuickTime 3 media in Shockwave movies, keep these points in mind:
![]() |
The QuickTime 3 media does not appear on stage until it is fully downloaded. Once it is fully downloaded, it begins to play (unless the member's pausedAtStart property is set to TRUE or the controller of member property is set to TRUE ). |
![]() |
Once QuickTime 3 media begins to download, the download continues until it's finished, even if the sprite no longer appears on the stage. Use the percentStreamed of member property to test how much of the media has downloaded. |
![]() |
Once a QuickTime 3 media file has finished downloading, its sprites will use the file without downloading it again, as long as the file remains in Director's file cache. |
![]() |
When authoring for Shockwave, do not use the movieTime of sprite or movieRate of sprite properties. Instead, use the mTime of sprite and mRate of sprite properties. |
![]() |
If a Lingo script refers to properties or uses functions that require information about QuickTime 3 media that has not finished downloading, the script receives only default information. Use the mediaReady property to determine if a file has fully downloaded. |
For a list of existing Lingo commands that you can use in Shockwave movies, look up "net Lingo elements" in the index of Director's online Help.
