Using The Flash Local Connection Object - MACROMEDIA DIRECTOR MX 2004-USING DIRECTOR Use Manual

The callback handler could look like the following:
on dirOnStatusHandler (me, aInfoObject)
if (aInfoObject[#level] = "error") then
member("chat input").text = "Error sending last message."
end if
end

Using the Flash local connection object

Flash includes an object type called local connection. The Flash local connection object can be
very useful for allowing separate movies on the same computer to connect to and communicate
with each other. Because the local connection object is a Flash object supported in Director, it can
allow communication between separate Flash content, Director movies, or combinations of the
two. You can use the messaging capability of the local connection object for simple tasks such as
exchanging sprite property data, or for more complex ones such as exchanging chat messages
when used in conjunction with the Flash Communication Server. For more information, see
"Using Flash Communication Server MX 2004" on page
To use the local connection object, you can either create a global local connection object or
associate the object with a Flash sprite in the Score. Once you have created the object, you can
control it entirely through script. The following are examples of a script that is attached to a Flash
sprite in channel 1 of the Score. The script contains a
that manage the local connection object.
Initialize properties
The first thing to do is declare some properties that you will use throughout the local connection
script to store references to the local connection object and 2 connections, one outgoing and
one incoming.

The beginning of the script might look like this, including the start of the

Creating the local connection object
The next step is to create a new local connection object. Once the object is created, you can use

other movies and send messages.
