| Hello All! I am pretty green to this stuff but I have a question that I haven't been able to figure out. I am trying to make an attack trigger:
^(.*) attacks (.*)
kill %2
The problem is that the period at the end of line is getting passed:
Joe attacks Foo.
attack Foo.
No such thing as Foo.
I can't figure out how to make it not read the "." at the end of line. Does anyone have any ideas?
Thanks!

| Well the problem is that . and * are both special characters, so you need to do the following:
^(.*) attacks (.*)\.
This should match anything with that pattern that 'ends in' a period. If there are times it won't you might need to add a set of '[]' around the '\.'. ;) As is always the case there are half a dozen ways to do it with regex depending on how accurate you need to be. lol

| Thank you for the help. I tried that, with and without the brackets and it won't work. When it passes %2 I no longer see the period, however, I still get the following:
Joe attacks Artificer.
kill Artificer
You see no such thing to kill here.
I wonder if it is passing some kind of hidden character? Any clues?
Thanks again!

| Hmm.. I would say that the mud is expecting to recieve a lowercase verion and the trigger retrieves an uppercase one. i.e.:
mud expects> artificer
you're giving it> Artificer
No easy way to fix this unless you move the send text to a script like the following:
sub attackit(trigname, output, wildcards)
world.send "kill " & lcase(wildcards(2))
end sub
I don't believe there is any other way to fix the uppercase letter in there and that 'looks' like the most likely problem. | | Top |
