Using the Multiuser Xtra
The Multiuser Xtra takes messages sent from movies and checks them for errors. The Xtra then prepares the messages for transmission over a network. Movies that use the Multiuser Xtra can exchange information in three ways:
![]() |
By sending it to the Shockwave Multiuser Server, which then sends it to the intended movie or movies |
![]() |
By establishing peer-to-peer connections directly with other movies, bypassing the Shockwave Multiuser Server |
![]() |
By connecting to a text-based server such as a standard mail server or Internet relay chat server |
The Multiuser Xtra extends Lingo by adding new commands and other elements to the Lingo vocabulary. You can use the Xtra with multiuser behaviors, or with other Lingo scripts.
In addition to Director, the Shockwave Player also includes the multiuser Xtra. If you're creating a projector, however, you must add the Multiuser Xtra to the movie's Xtras list. See About Xtras.
