N        This condition can be used to check if a client with the given name exists on the server or not.

It takes only one parameter, the client name.


The client name must only be similar to the passed name to match; for more details, see Unicode notes.


This condition will only create an error if you pass a blank client name. In other scenarios, such as the server not hosting, it will simply return false.


In a Connection > On disconnect event, the disconnecting peer is considered to NOT exist by this condition. This is because it is removed from the server's main client list so the Client > Number of clients on the server expression excludes it during a disconnect event.


This condition does not change the currently selected client.
