Bjarne,
Aha. The problem is that net operations need to be asynchronous.
That is, you have to issue the operation and then come back every
once in a while and check. But a tight repeat loop doesn't give the
processor any time to do this. Instead, use a behavior something
like this (untested):
property spriteNum
property pURL
property pNetID
property pfComplete
on beginSprite me
-- Start the operation and store the netID
pNetID = getNetText( <Your URL> )
-- Set the completion flag to FALSE
pfComplete = FALSE
end
on exitFrame me
-- Only continue if the operation hasn't completed
if pfComplete then
go to the frame
end if
-- If the operation for this ID is completed then check the results
if netDone(pNetID) then
-- Get the result text from the operation
textFromNet = netTextResult( pNetID )
-- Check that the result is OK and not an error
if netError( pNetID ) = "OK" then
-- Got it
-- do whatever you want with "textFromNet"
end if
-- Set the flag that the operation has completed
pfComplete = TRUE -- or move on to another frame, etc.
end if
end
