I'm trying to find a way to set this trigger to target "robber" or "imp" but when there are more than one creature in the room, the line reads like this...

In this room you see: 1st grave robber, 1st grave imp, 2nd grave robber, etc.

When there's only one it reads like this...

In this room you see: 1st grave robber


So how do I isolate "robber" or "imp" without capturing the rest of the line? The first thing I thought was to make a limit on the capture to 3 characters, but I don't know -anything- about coding, so I'm basically teaching myself this stuff as we go. Any help would be appreciated.
Trigger below:

Quote:
<triggers>
<trigger
enabled="y"
expand_variables="y"
group="HuntGY"
keep_evaluating="y"
match="^In this room you see\: 1st grave *(.*?)$"
regexp="y"
send_to="12"
sequence="100"
>
<send>--Sets target variable to "grave *" for further fighting.
Execute ("t %1")

--Sends kill command first time via alias "kill"
Execute ("kill")

--Displays target in bottom left
SetStatus ("Target: %1")
</send>
</trigger>
</triggers>


Edit: Version 4.43

Based on your attempt, it looks like you're maybe trying to get this?


^In this room you see\: 1st grave (\w+)


That will put the first alphanumeric sequence following "grave" into %1, ending at the first non-alphanumeric character.

Okay, so far that works great. Thank you.

... Now to make it a little more complex. what if "1st zombie" was a possible mob too?
I'm simply trying to find a way to combine this so I don't have 3+ triggers to hit the three + mobs that may be here...

Right now I'm thinking something along the lines of

^In this room you see\: 1st (zombie)|(?:grave (\w+))


The only thing about this pattern is that if it's zombie, then zombie will be in %1, but if it's grave <something> then the something will be in %2 and not in %1. So you'll need to, in your script, check explicitly to see if "%1" == "zombie" and if not then use %2

Make sure you wrap that | in a group (), or it'll alternate between "^In this room you see\: 1st (zombie)" and "(?:grave (\w+))".

Or, if you are looking for "zombie" or "grave robber" then allow for a space, eg.


^In this room you see\: 1st ([%a ]+)


Now %1 might be "grave robber" or "zombie". And since extra ones have a comma before them, that will terminate the search for characters.

Will it capture "grave robber" that way? I need just robber/imp captured if its one of those two... thank you all for your help.

What is %a? I know \a matches a bell character, but that doesn't make sense either

Ooops, sorry I was in "Lua mode". In Lua that would be "an alphabetic character".


^In this room you see\: 1st ([A-Za-z ]+)

Try it and see. It should (or the amended one should). Just to explain, inside the brackets are groups of things, like A-Z and a-z for alphabetic characters, upper and lower case. Plus a space so we capture the space between "grave" and "robber".

How would I get it to only plug "robber" "imp" or "zombie" when the names are grave robber or grave imp? My game wont accept "kill grave robber"

That is one of my pet hates. 


In this room you see: grave robber

> kill grave robber

There is no grave robber here.

...

There is a silver sword lying here.

> take silver sword

There is no silver sword here.

More generally (in case it isn't always the word "grave") you can get the last word. For example:


mobname = "big fat ugly grave robber"

last_word = string.match (mobname, "[%a]+$")

Send ("kill " .. last_word)



That sends "kill robber".

Okay, so far this is what I have...


<triggers>
  <trigger
   expand_variables="y"
   group="HuntGY"
   keep_evaluating="y"
   match="^In this room you see\: 1st ([A-Za-z ]+)"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>--Define mobset prior to running
mobname = "grave robber"

--Checks to see if creature in the room is in mobset and if so, sets the last word of name as "last_word"

last_word = string.match (mobname, "[%a]+$")

--Command to kill mob if match is made from mobset
Send ("kill " .. last_word)


--Sets target variable to mob for further fighting.
  Execute ("t ".. last_word)

--Displays target in bottom left
SetStatus ("Target: %1")
</send>
  </trigger>
</triggers>



and it works great... for robbers. It's actually -only- trying to kill robbers, even if there are only grave imps in the room, though.

This is a standard set up of what i see when I look:



[Ancient Graveyard]
Paralleling the widening path are empty holes in the ground. The realization that these empty holes once held not only a coffin, but a body, becomes abundantly clear by the broken wood and scattered bone fragments still lying around. The large oak trees that surround these desecrated graves stand silently, their only purpose to drop their leaves and fill in the gaping holes.


The area is illuminated.

In this room you see: 1st grave robber, 1st grave imp, 1st zombie, 2nd grave imp
In this room are: large oak tree
Obvious exits are: northwest, south


Now I want it to ultimately kill any (and all) of these. But I need it to pick one target. But not necessarily just the grave robber. As it's currently set up, if there are only grave imps, it still tries to kill a grave robber... what would I need to do to fix this and make it viable to attack any of those three mobs?

Well, mobname = "big fat ugly grave robber" was purely a test case to demonstrate the idea.

Change:


mobname = "grave robber"


to:


mobname = "%1"
