Local Variable in the trigger pattern
|
Is there a way to create a local variable off the trigger pattern like using the &variable to make a regular variable. I'm trying to create a trigger that will take all the gold silver and copper I get from selling stuff and telling me how much total I made.
| Code: |
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<trigger priority="19280">
<pattern>{Shopkeeper|Merchant} gives you {$goldsell gold|$goldsell gold $silversell silver|$goldsell gold $silversell silver $coppersell copper|$goldsell gold $coppersell copper|$silversell silver $coppersell copper|$silversell silver|$coppersell copper} for</pattern>
<value>#variable sellgold {%eval($goldsell*100 + $silversell*10 + $coppersell)}
soldfor</value>
</trigger>
</cmud>
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<alias name="soldfor">
<value>#say %ansi(7)You have now sold shit for a total of %ansi(14)@SellGold gold%ansi(7).</value>
</alias>
</cmud>

That's what I have so far. The problem is I could get gold silver and copper or just gold and copper or gold and silver or any combinations. Gold=100 copper, silver=10 copper, so I can get an output in all copper which would be fine, while creating a variable for each would work, love to use new settings and the localvariable here seems like the best bet.
Thanks,

Try this regex:
| (Shopkeeper|Merchant) gives you (?:($goldsell:\d+) gold )?(?:($silversell:\d+) silver )?(?:($coppersell:\d+) copper )? for |
This (localvar:wildcard) syntax is the proper way to refer to local variables in patterns, and (something)? means that it can be the word "something" or nothing.
I had to use a regex because you can't use wildcards inside CMUD's {something|something else} syntax. |

Thank you Fang Xianfu. Is there a way to trigger local vars in the pattern with CMUD's syntax if it's not in the {something|something else}? I know it will come up in plenty of other situations.
Thanks a ton,

Yep, just use ($localvar:wildcard) like I did in that regex.

What you wrote for me Fang isn't working it's not matching the pattern... not sure what to do

Whoops I didn't set it as a regular expression. Pattern is matching now, but it doesn't seem to be setting the local variables.
| Code: |
Shopkeeper gives you 12 gold 123 silver 23 copper for
|
| Code: |
%1 : Shopkeeper
%2 : 12
$goldsell : 123
%4 : 23
|
That is what I get when I go to test pattern matching |

I made a mistake in the regex (extra space, and I also forgot to make the first brackets non-capture), you should use this one instead:
| (?:Shopkeeper|Merchant) gives you (?:($goldsell:\d+) gold )?(?:($silversell:\d+) silver )?(?:($coppersell:\d+) copper )?for |
As for the captures not capturing, I have no idea what could be causing it. It works fine with simpler triggers - seems like a bug. |

This is matching now, but instead of $goldsell it's giving me %1, instead of $silversell it's giving me %2, and instead of $coppersell it's giving me $goldsell... I don't know how regex works...so umm fix it fix it fix it?  hehe thanks for everything so far though Fang

Well, for now you can probably just remove the local variable references in the pattern and use %1-3 instead. If you actually need to use them as local variables (you're doing stuff with them later) then you can just do $goldsell=%1 and whatnot.
