Writing callback handlers
For callbacks to work, you must write the callback handlers themselves. In this example, the
methods are all inside a
beginSprite
because they are handlers by themselves. In this example, the callback handlers are located in the same script
attached to the Flash sprite, just after the
The event is generated each time the local connection object sends an outgoing message. The
onStatus
handler might look like the following:
on myOnStatus (me, aInfoObject)
if (aInfoObject[#level] = "error") then
member("chat input").text = "Error sending last message."
else
member("chat output").text = member("chat output").text & RETURN & member("chat

end if
