I'm trying to write a script that will go a random direction out of a room. I've got variables for all the room numbers that I want to do, as well as all of the rooms' exits, but here's where I have problems. This is basically what I have so far. Let me know if you need further explanation. Hopefully, this will kind of explain itself when you see my settings below.

#ECHO Current room is ~*~*@current_room~*~* (This will always be an integer)

#TRIGGER {Current room is ~*~*(%n)~*~*} {#var temp_curr_room %1}

#1 {%item(@room_'@temp_curr_room'_exits,%random(1,%numitems(@room_'@temp_curr_room'_exits)))}

Basically, what I'm trying to do is get the integer value (@temp_curr_room) to expand inside the @room_##_exits variable. That way, I can randomize the exit based on a random number between the choices in @room_25_exits (just an example).

So how can I get the temp variable to expand inside the other variable, thereby completing it? I'm totally stumped on this one, so I appreciate any help. Thanks!

According to the help for variables, the proper thing to use are braces.

@room_@{temp_curr_room}_exits

Hmmm... it doesn't seem to work. I'm not getting errors anymore, but the '_exits' part isn't being treated as part of the variable. Here's what I'm looking at:

#var new_room %random(1,%numitems(@room_@{temp_curr_room}_exits))
@current_room = %arrget(@room_@{temp_curr_room}_exitnumbers,@new_room)
#1 {%arrget(@room_@{temp_curr_room}_exits,@new_room)}

I'm stumped... I'm gonna keep trying things, and see if they work. Thanks for more help in advance!

Try enclosing the entire variable name with {}:

Ok. Here's the settings I have for the current room. The braces highlighted in red should be recognized as part of the variable, but they aren't. I've tried the braces in all different places, but they just don't seem to work. I want the script to grab a random number from 1-x, where x is the number of items in the roomexit_xx and roomexitnum_xx variables. So, in this instance, it should pick between 1 and 5. Then I want it to send that command to the mud from the roomexit_xx variable, and set the current_room variable to be equal to the same position in the roomexitnum_xx variable.

#ALIAS newroom {#ECHO Current room is ~*~*@current_room~*~*}
#ALIAS newroom2 {#VAR new_room {%random(%numitems({@roomexit_@{temp_curr_room}}))};current_room = %arrget({@roomexitnum_@{temp_curr_room}},@new_room);#SEND {%arrget({@roomexit_@{temp_curr_room}},@new_room)}}
#TRIGGER {Current room is ~*~*(%n)~*~*} {#VAR temp_curr_room %1;newroom2}

#VAR current_room 2
#VAR roomexitnum_02 {1|5|3|54|42}
#VAR roomexit_02 {n|e|s|u|d}

Example:

Current room is **2**
(random number picked is 4)
current_room should now equal 54
The command "u" should be sent to the mud, moving me up.

I hope this makes sense, and someone can help me figure out what is going wrong with it. I've turned this over in my head so much that I think I'm going to go crazy.

You using %arrget with a list variable. The correct function to use would be %item.

Also braces used with the @ should surround only the variable name:
@{roomexit_@{temp_curr_room}}
In this particular case neither set of braces is necessary, because you renamed your variable from your first script to simpler names that the parser will figure out without help.

As I said earlier, use braces around the variable name: @{room_@{temp_curr_room}_exits}
not {@room_@{temp_curr_room}_exits}.

Second problem: roomexitnum_02. Your trigger will set temp_curr_room to 2, not 02. That means the last part of your script is referencing to variable Roomexitnum_2, not Roomexitnum_02.

Third problem: You're using %arrget when only %item is needed.

In all, rename your variables and change your script to:

#ALIAS newroom {#ECHO Current room is ~*~*@current_room~*~*}
#ALIAS newroom2 {#VAR new_room {%random(%numitems(@{roomexit_@{temp_curr_room}}))};current_room = %item(@{roomexitnum_@{temp_curr_room}},@new_room);#SEND {%item(@{roomexit_@{temp_curr_room}},@new_room)}}
#TRIGGER {Current room is ~*~*(%n)~*~*} {#VAR temp_curr_room %1;newroom2}

Works like a charm! Thanks much! I knew there was something I was overlooking, and I had a feeling it had to do with the %arrget function, but for some reason I couldn't remember the %item function. Thanks for all your help!
