Setup:
1A. My character can find hidden mobs
2A. My character "marks" mobs for the tank to hit
3A. If no mobs of the target level are in the room, I tell the group to move on to the next area

What I want:
1B. To parse all of the mobs in the room
2B. Search for 5 specific short descriptions
3B. If the first is present, do "mark <mobname>", and end the searching so the Tank can attack them mob he'll se as marked
4B. If the first is not present, search for the 2nd, etc.
5B. If none are present, do "grouptell None here.", and end

My Questions:
1C. How do I set that up in an if/then/elseif?
2C. Do I use string.find or string.match to look for part of the short desc?

I could set it up with simple triggers, but if I try to use the mob's short desc to match a trigger, then if multiples are present, all of those triggers fire, marking multiple mobs instead of just 1.

Any help, and any pointing to appropriate examples would be greatly appreciated.

Not the scripting answer you are after, but since you mentioned trying to get simple triggers to work...


To stop multiple triggers from firing just put them into the same group and have each of them "EnableTriggerGroup ("groupname", false)" when they fire.

This wont let you do priorities, like kill mob B before mob A if they are both in the room. But after one trigger in the group fires, the entire trigger group gets disabled and wont continue to fire for every following mob(like, mark a, mark b, mark c.)

a 2nd trigger or alias to "EnableTriggerGroup ("groupname", true)" when your ready to mark your next target and your good to go.

Good idea Chyort! I used something like that a long while back, and may have to again. It just makes each trigger so big...it feels bloated. Here's what I was wanting, in "metacode". I know what I want it to do, I just don't know the syntax to get it there.

Things in bold are what I'm looking to find the syntax on how to do them.


something that tells the script to parse the output from the MUD when I autolook going into a new room

if 'short description A' is in the parsed text then
  Send ("mark mobA")
  break
elseif  'short description B' is in the parsed text then
  Send ("mark mobB")
  break
elseif  'short description C' is in the parsed text then
  Send ("mark mobC")
  break
elseif  'short description D' is in the parsed text then
  Send ("mark mobD")
  break
elseif  'short description E' is in the parsed text then
  Send ("mark mobE")
elseif none of the short descriptions are found then
  Send ("grouptell None here")
  end
end


I just don't know the proper syntax to use. :(

Something like this:


<triggers>
  <trigger
   enabled="y"
   match="You see * here."
   send_to="12"
   sequence="100"
  >
  <send>

mobname = "%1"

specialMobs = {
  { desc = "short description A", send = "mark MobA" },
  { desc = "short description B", send = "mark MobB" },
  { desc = "short description C", send = "mark MobC" },
  { desc = "short description D", send = "mark MobD" },

-- add more here ...

  }  -- end of table

for k, v in ipairs (specialMobs) do
  if string.find (mobname, v.desc, 1, true) then
    Send (v.send)
    return
  end -- if found
end -- for each table item

Send ("grouptell None here")

</send>
  </trigger>
</triggers>


The table contains what to search for, and what to send.

Ok, so here's what I have so far. I have 2 questions, and then will supply data to hopefully help.

Questions

  1. 1. I may be doing my wildcards incorrectly, and need some guidance there.
  2. 2. This script fires a "mark <mob>" or "gtell None here." on EACH mob in the room. Is there a way to alter it to parse the whole room and either fire on the first, and break, or do a single "gtell None here." if none are present?


Data

Auto-look when entering a room: (mobs I want in bold)

Inside A Small Cave
  The air here is dank and gloomy.  Shadows dance and play about the
walls as light filters through cracks in the roof of this small shaft
leading into the mountain.  Dripping water can constantly be heard, as
well as other, more ominous sounds from deeper within.
       
   | | 
   | | 
   |*|_
   |_  

[5 am Full Moon][17, Nov-Fall] [LoS = 5'] 

[Exits: north south]
(M) (weak) A small mouse is here, squeaking at you.
(M) (wimpy) A water bug skitters over a small puddle.
(Hidden) (F) (even) A goblin slinks in a corner, with a knife already drawn.
(M) (weak) A small mouse is here, squeaking at you.
(Hidden) (M) (challenge) A large shadow looms over you.
(Glowing Aura) (F) (hard) A rock troll towers over the room.


And my script, based on what Nick graciously gave me.

<triggers>
  <trigger
   enabled="y"
   match="(^|>)(.+)\((even|challenge|hard|insane)\) (.+)"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>

mobname = "%1"

specialMobs = {
  { desc = "A goblin slinks in a corner, with a knife already drawn.", send = "mark goblin" },
  { desc = "A large shadow looms over you.", send = "mark shadow" },
  { desc = "A rock troll towers over the room.", send = "mark troll" },

-- add more here ...

  }  -- end of table

for k, v in ipairs (specialMobs) do
  if string.find (mobname, v.desc, 1, true) then
    Send (v.send)
    return
  end -- if found
end -- for each table item

Send ("gtell None here")
print "%1"
print "%2"
print "%3"
print "%4"
print "%5"


Question #1

  • The "print"s are so I could see what my wildcards actually were...didn't know another way.
  • The following is what the room shows when using this script when printing the wildcards. Don't understand why %4 is the one I need
  • mobname = "%4" works just fine, I just want to understand WHY its the 4th wildcard

(Hidden) (F)
even

(M) (weak) A small mouse is here, squeaking at you.

(Glowing Aura) (F) (hard) A rock troll towers over the room.gtell None here

(Glowing Aura) (F)
hard
A rock troll towers over the room.


Question #2

  • If I expand my trigger match to "(wimpy|weak|even|challenge|hard|insane)" to match every mob possible, I then get the following.
  • I would rather have the script match once, send the matched mark, and break OR match none, send the gtell ONCE and break

I think you are matching on the wrong wildcard for a start.

You should probably name it.

eg.

Change:


   match="(^|>)(.+)\((even|challenge|hard|insane)\) (.+)"


to:



   match="(^|>)(?P<mobname>.+)\((even|challenge|hard|insane)\) (.+)"


And then change:


mobname = "%1"


to:


mobname = "%<mobname>"

This would need something extra because the trigger matches each line. You need something that indicates the end of the mobs in the room (like, the next prompt).

Your trigger could set some flag, eg.


if not foundMobs then
  mobCount = 0
  foundMobs = true
end -- if


Then add one to foundMobs if you find a match.

And then the other trigger (eg. on the prompt) could test for foundMobs and check mobCount, eg.



if foundMobs then
  if mobCount == 0 then
    Send ("gtell None here")
  end -- if none cound
  foundMobs = false
end -- if
