| 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?

<triggers>
<trigger
custom_colour="16"
enabled="y"
group="ZZZ TEST General Moving"
match="^((.+?) leaves (.+)\.|(.+?) arrives (.+)\.|(.+?) gallops (.+)\.|(.+?) slithers (.+)\.|(.+?) rides (.+)\.)$"
regexp="y"
send_to="12"
sequence="100"
>
<send>print(" parameters:==> 0:","%0","1:","%1","2:","%2","3:","%3","4:","%4","5:","%5","6:","%6","7:","%7","8:","%8","9:","%9")</send>
</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!) | | Top |

| 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. | | Top |

| 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<mob>.+?) hits you\.|(?P<mob>.+?) kicks you\.)$"
regexp="y"
send_to="12"
sequence="100"
>
<send>
mobname = "%<mob>"
print ("mobname = ", mobname)
</send>
</trigger>
</triggers>

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. | | Top |
