Description

This returns TRUE if the world is currently connected.

See GetInfo (227) for more details about the exact connection status.

There are actually a number of connection "phases" because connection is not synchronous. That is, connecting takes time.

If you are using a proxy server, with a username/password, there are 8 phases as described below. Not all phases are necessarily done, for example if the MUD address is already a "dotted decimal" number then a MUD name lookup is not required.

They are:

0=not connected (and not attempting to connect)
1=MUD name lookup (converting MUD name to an IP address)
2=Proxy server name lookup (converting proxy server name to an IP address)
3=connecting to MUD (establishing TCP/IP connection to the MUD)
4=connecting to proxy server (establishing TCP/IP connection to the proxy server)
5=proxy server phase 1 (sent SOCKS authentication method, awaiting confirmation)
6=proxy server phase 2 (sent SOCKS username/password, awaiting confirmation)
7=proxy server phase 3 (sent SOCKS connect details, awaiting confirmation
)
8=connected to MUD (fully connected)

Strictly speaking, IsConnected returns true if the connection phase is 8 (connected to MUD) and false for any other phase.

VBscript example

world.note world.IsConnected


Jscript example

world.note(world.IsConnected());


PerlScript example

$world->note($world->IsConnected());


Python example

world.note(world.IsConnected)


Lua example

Note(IsConnected())


Return value

TRUE if world connected
FALSE if not connected

Note: TRUE is a non-zero value, FALSE is the value 0.
