GetExitByLink ( object from room , object to room ) returns a string or null.

How do I use this? I get this error message: Error running script: Object reference not set to an instance of an object.

Sorry, had to edit... What I'm trying to do is check to see if I had created an exit so I wouldn't create the same exit later (with the same name. I'm assuming that too would generate an error). If I hadn't created an exit, is there something else I can use to check for this? At this point, I'm not sure how to handle the errors and I am trying to make it so my game generates exits randomly each time it starts.

Thanks.

You can call GetObject to get the actual exit object.

s = GetExitByLink(Room111, Room311)

if (s = null) {
  msg("There is no such exit")
} else {
  exit = GetObject(s)
  msg("exit " + exit.name + " from " + exit.parent + " to " + exit.to)
}

(I hope it's ok I just write in direct script. It should be translatable to the GUI. If it's not, ask and I'll help.)

I'll try this. Thanks I like the code. Any examples (especially short ones) will help.
