I'm trying to create an alias that will, for each argument, send the argument to the mud, wait for specific text, and then send the next, wait, &c. Obviously I can use #TEMP to delay until the text arrives (the text will be the same regardless of the item sent to the mud), but it's the body of the trigger I'm having trouble with, as I don't see any way to shift arguments (so %2 becomes %1, %3 becomes %2) to deal with all of them. Anyone have any suggestions?

Can you give us the exact output you're using for your trigger? Hard to help without nothing at all to go on. As for arguments, all I could suggested given the explanation you've currently provided us with... if you have several arguments inside the trigger line, use %w for them, inside the code, use %1 = , %2 = etc. %1 is accordingly first %w in line, %2 is second and so on.

It sounds like you want to use a string list and the %pop command in your trigger. Still an example pasted from the mud of what you are trying to do would be helpful.

The text is "following you." The arguments to the alias would be a series of move commands. The idea is to wait after each one until the object following me arrives in the current room before moving on to the next.

As for using string lists, I thought about that. I just would find something like:

cmove w w n n ne

to be a bit more intuitive than

cmove w|w|n|n|ne

hmm, that's close, but not quite right. I do want the trigger to be a one shot, so maybe:

Ok, did some experimentation, and came up with this, which almost works:

I know it may not be exactly what you are looking for, but how about using the movelist to create a temporary path that can then be use with #slow, #stop, and #step triggers?

You should really be using brackets () rather than braces {} around the expression part of the #if command. I'm surprised that %pop(movelist) works too, I'd've thought it should've been %pop(@movelist). Either way, you need to add an #exec command before it or it won't work with commands of more than one word. Perhaps you should also change the #var movelist {%1} to %-1 in case the commands contain spaces. Seems like you could make that alias a bit simpler by not repeating sections of code you don't need to:

#alias cmove {#if (%1) {#var movelist {%1}};#if (%numitems(@movelist)>0) {#exec %pop(@movelist);#temp {following you} {cmove}} {#echo Arrived}}

If you wanted a version that used #t- and #t+ you'd want something like this:

#alias cmove {#if (%1) {#var movelist {%1}};#if (%numitems(@movelist)>0) {#exec %pop(@movelist);#t+ CMoveTrig} {#echo Arrived;#t- CMoveTrig}}

#trig "CMoveTrig" {following you} {cmove}

Check the helpfile Fang %pos

Syntax: %pop(listname)

Retrieves the first item from the list named by "listname" and then removes this item from the list.

Note that the argument is the name of the list variable, not the @var reference.

After some more experimentation, including breaking speedwalk, I had an epiphany, and came up with a dead simple way to do this, without any variables or permanent triggers, and without having to futz about with lists:
