Assuming your MUD always displays the room exits with the room description, doesn't use MXP to display room exits and doesn't have a "backwards" exit, you'll first want to make a trigger that captures the available exits, parses them and stores them in a variable.

If your mud gives you:

Exits: South, southeast, and southwest.


You need to match "Exits", take the exits, and throw away the "and" and the "." You probably want to get rid of the spaces or the commas as well, to give you a variable that's either a bunch of exits separated by spaces, or by commas.

<triggers>
  <trigger
   enabled="y"
   match="^Exits: (.*)."
   regexp="y"
   send_to="12"
   sequence="100"
   other_text_colour="black"
   other_back_colour="black"
  >
  <send>temp=replace("%1", "and ", "")
temp=replace(temp, ",", "")
world.setvariable "exits", temp</send>
  </trigger>
</triggers>


If your MUD sends exits differently, you'll have to modify either the match line, or the code a leetle bit. It depends. :)

Secondly, you'll either want to make a trigger to detect when you're low on hitpoints and make it send a direction from the list. Or you'll need to add a bit to your existing score script if you've got one.

<triggers>
  <trigger
   enabled="y"
   match="<Hp: (.*?)/"
   regexp="y"
   send_to="12"
   sequence="100"
   other_text_colour="black"
   other_back_colour="black"
  >
  <send>if cint("%1")<=100 then
  world.send split(world.getvariable("exits"), " ")(0)
end if</send>
  </trigger>
</triggers>


This will match a mud that sends a score line like 
<Hp: 10/100 Sp: 50/50>
If yours is different, you'll have to alter the "Match" line to take account of that.

One thing to note is that this will always send you in the first direction listed. If you're a purist and want to make it random, you'll have to alter the world.send line.

Hope this helps. :)

I've been trying to adapt this trigger to lua, but without success so far. Here's what I've got:

For the regular expression:
^You see exits leading (.*).

It returns the command:
world.setvariable('exits', 'Replace("%1", "and ", "")')

Here's the error message:
Run-time error
World:
Immediate execution
[string "Trigger: "]:1: attempt to call field 'setvariable' (a nil value)
stack traceback:
[string "Trigger: "]:1: in main chunk

Help me please. I've spent several hours trying to troubleshoot what really ought to be simple enough to do already.

See http://www.gammon.com.au/scripts/function.php?name=SetVariable

Note that it's just SetVariable(...).

Also note the capitalization.

To amplify on that response, VBscript is not case-sensitive, thus you can write "setvariable".

However in Lua you have to get the case right, so you need to write SetVariable.

See the help file, or the online documentation, you must use the exact spelling and capitalization documented there.

If you are using the Trigger editor, you can type a partial word (eg. "setvar") and then hit the Complete button to have it complete the word, with correct capitalization.

Your other problem is you have quoted the call to Replace, which means that it would simply put the words "Replace("%1", "and ", "")" into the variable "exits".

Yep. That's exactly the problem now. I had hoped that the script would still process the replace command to filter my possible exits for me. I want to be able to create an alias to be able to leave a room quickly. I really don't know what I need to do next to get to my goal.

What I was getting at, was you have to remove the quotes, like this:


<triggers>
  <trigger
   enabled="y"
   match="^You see exits leading (.*)\.$"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>
SetVariable ('exits', Replace("%1", "and ", ""))</send>
  </trigger>
</triggers>


If you quote "Replace (...)" it just becomes a string. If you want a function call, you can't quote it.

I also put a backslash before the final period in your regular expression. If you are matching on a period you must put a backslash in front of it, because a period on its own is a wildcard.

You could save yourself a bit of trouble by building a table of exits, like this:


<triggers>
  <trigger
   enabled="y"
   match="^You see exits leading (.*)\.$"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>
exits = {}  -- start new table
for e in string.gmatch ("%1", "%%a+") do
  if e ~= "and" then
    table.insert (exits, e)
  end -- not "and"
end -- for
</send>
  </trigger>
</triggers>


What that will do is make an "exits" variable (a Lua variable, not a MUSHclient variable), that contains an entry for each exit. It uses string.gmatch to find words in the matching trigger string, and insert them into a table, excluding the word "and".

Now if you want to flee, you can randomly choose one, like this:


<aliases>
  <alias
   match="flee"
   enabled="y"
   send_to="12"
   sequence="100"
  >
  <send>
if type (exits) == "table" then
  Send (exits [math.random (#exits)] )  -- choose one
end -- we have some exits
</send>
  </alias>
</aliases>
