But it isn't working like I think it should. I don't get a message when I use the command open door. I simply don't understand what I am doing wrong. I have tried using #object# instead of thing, but that just doesn't work either.
Can someone please tell me what I am doing wrong?

Again, I'm not 100% confident but perhaps if you try swapping "< door = #thing# >" to "< #thing# = door >" then that might work...

Try it and get back to the forums...

Here is a very basic working example of an openable door that creates an exit when opened. In this case trying to open the door a second or third time tells you "it is already open"

This is ONE way to do it, and relatively simple, but it is not the best. Ideally you should create an openable type and have open / close actions with traps for repeated use, messages when things are opened and closed, varying descriptions etc..

All the above features are included in the 'openable' type that is part of my Q3EXT library, which might be worth looking at to see how it works even if you don't use it.

A simple syntax error is preventing your code working as expected. The line:

quote:

---

action <close> if property <$thisobject$; not closed> then {

---

quote:

---

action <close> if not property <$thisobject$; closed> then {

---

That'll cure it!
