Once again I go ACK TTTTHHHHHPPPPPPTTTTTTT!

Ok, here is what I have...
I am randomly creating a list of room exits. (There are reasons for not using paths)

For example the mud output will be like the following...

Obvious exits:
East - A Jade Trail
West - A Jade Trail

I trigger "Obvious exits", "North -", "South -", "East -", and "West -"
each of these I give a boolean value to represent if this is a viable direction at the present time.

I then set a TICK TIMER to display #SH Moving right along

I trigger that with the following code...
----------------------------------------------------------
#GAG
ExitList=""
ItemCount=0
#if (@ExitEast) {
#ADDITEM ExitList {East}
#ADD ItemCount 1
}
#if (@ExitWest) {
#ADDITEM ExitList {West}
#ADD ItemCount 1
}
#if (@ExitNorth) {
#ADDITEM ExitList {North}
#ADD ItemCount 1
}
#if (@ExitSouth) {
#ADDITEM ExitList {South}
#ADD ItemCount 1
}
@ExitList.%random( 1, @ItemCount) <---- Here is problem
ExitNorth=0
ExitSouth=0
ExitEast=0
ExitWest=0

----------------------------------------------------------

The results I get from this is "East|West.2" or "East|West.1", not the desired "East" or "West" that I would get from #SHOW @ExitList.1 or #SHOW @ExitList.2

Would someone plz kick me in the right direction here.

Thanks and Regards...

%item( @ExitList, %random( 1, %numitems( @ExitList)))

EDIT: Changed %len to %numitems.

Try this
Change line to #EXEC @ExitList.%random( 1, %numitems(@exitlist))
and get rid of the #ADD lines as it is no longer needed

And if your using Lightbulbls example I think you want %numitems() and not %len

And here is a Complete rewrite using alarms and stringlist:

#CLASS Exits
#TR "exitstr" {Obvious exits:} {
exits=""
#TEMP "exitstemp" {^$} {
#STATE exitstr 0
#ALARM "exits" {+5} {#EXEC %item(@exits,%random(1,%numitems(@exits))}
}
}
#COND {(%w) - *} {
#ADDITEM Exits "%1"
} {looplines|param=10}
#CLASS 0

Oops.

Good catch. I fixed it.
