Trigger:
^((.+?) attacks you\.|(.+?) wakes up and starts hitting you\.)@

I need to assign monster name to a variable, so that i can refer it later, for example targetting the right monster.

After numerous help file/forum/whatnot browsing, testing and thinking, I _still_ fail to do this.

I hope my example is clear and enough for an easy answer, and I am sane enough to understand it :P

Well in your case the monster name will be %1 (or maybe %2 because you have a bracket inside a bracket) inside the "send" box.

Perhaps watch this?

  </trigger>
</triggers>


This example seems to put those player (or mob) names who _leaves_, to %2 and their direction to %3.
And those who _arrive_, names to %4 and direction to %5. And so forth...

What i need is to capture player (or mob) names to some variable what i can use later, say, targetting or telling.

How do i do that? Do I have to use GetWildcards, SetVariable, GetVariable or some other funcion? And is there a better ie. shorter way to write that <send>print(".....") part?

(Video was great, i learned few tricks to be used later, thank you for that!)

But what about inside regular expressions? How do i set some named variable (like: mobname) when i have several choices in the trigger, like:

^((.+?) hits you\.|(.+?) kicks you\.)$


What i noticed from my last message was that if the first one fires (activates) it falls into parameter %1, but the second one goes into parameter %2.

I need to grab the name of a mob that automagically attacks me when i arrive at the room. If I have only one type of information, say : "Snake attacks you!" then it is easy, it's always %1, but when there are more than one automatick attack message, then the next (.+?) goes into %2, third (.+?) to %3 and so on.

Oh, right. Well you can use named captures, and use the (?J) option to allow duplicate names.

Then the capture is called "mob" and you can extract that as shown.


<triggers>
  <trigger
   enabled="y"
   match="(?J)^((?P&lt;mob&gt;.+?) hits you\.|(?P&lt;mob&gt;.+?) kicks you\.)$"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>
mobname = "%&lt;mob&gt;"

print ("mobname = ", mobname)
</send>
  </trigger>
</triggers>


Template:pasting For advice on how to copy the above, and paste it into MUSHclient, please see Pasting XML.


The regexp part looks like this without the XML escaping:


(?J)^((?P<mob>.+?) hits you\.|(?P<mob>.+?) kicks you\.)$

Thank You!

That did the trick.
Now I can combine many triggers via regexping and reduce the total amount of triggers.

There are so many functions and different syntaxes that sometimes I get confused. I will code on... step by step.
