Error in cMUD.exe (There must be at least one field.)

So, last night I upgraded from CMUD 3.32 to CMUD PRO v3. A potential issue with this was that my friend purchased me the new copy. But I doubt it.

Anyhow, I downloaded the program, I foolishly changed the file extensions from default because my original CMUD packages were still on. Then I went to town coding. Everything ran fine until this morning.

The error started while I was polishing this turd I'd been working on for a bit. I use CMUD to learn coding when I'm not MUDing. So I guess this is a two part issue... anyways! Here's the issue with the code. I am trying to create a trigger which will ignore random length strings of words and only focus on specific words (that I intend to database). The purpose is to auto answer people who are asking for directions. Here's what I came up with.

#TRIGGER %1 ask '(*)(*)(*){nomad|nomads|nomad child}'} {IF (@CONDITION={nomad|nomads|nomad child})} {answer From Althainia Market Square: go 3west, 4north, 2east, 5north, all east.}

As you can see, it's not exactly pretty. So this morning I decided to continue playing around with removing random strings prior to and after the CONDITIONS. As I was doing this (basically messing with an exact copy of the above script but with minor changes for trial and error) I started getting error messages. Lots of them. So I deleted the string and they persisted. I then thought perhaps it had to do with file extensions. So I uninstalled and reinstalled. Now it's worse. Now I get the Error Message I posted as the subject.

I also tried to simply do a system restore. STILL DIDN'T FIX IT. Needless to say, I'ma sad panda.

If you have any suggestions on how to best create the code string I have above, please let me know. But more importantly, I don't want to lose my session package and start over from scratch. Damned thing is like 7mb.

I'm not sure how you want me to post the error report, so here goes:

Couple syntax issues I see in your #TRIGGER
1. no opening brace on the pattern.
2. using %1 (an as yet undefined variable) in the pattern instead of a wildcard
3. triple use of the everything wildcard '*', surely we can be a bit more precise in what we are expecting
4. basing things off a variable we don't seem to be ever changing the value of
5. capturing (substrings) of the pattern in parenthesis and not using them

This could certainly be cleaned up a good bit, but I would need to see sample strings of MUD output.
You may not need to use #CONDITIONs at all, state-based triggers can get tricky.

I would try opening your session offline and deleting the offending trigger for now and see if that fixes the error message at least.

I am unable to open the session offline even whilst holding shift. It freezes the client. It sends me that error message that I posted above. Probably time to give up and rewrite all that crap.

But as for the trigger. The output looks like this:

Krazeth asks 'Where does one find the nomad village?'
Thanatael asks 'How do I get to the gnomes?

Something like that. I was going to make it conditional so that I could keep from answering some questions based on keywords. For instance:

Boof ask 'What are the directions from Silversand Garrison to New Thalos?'

I wouldn't want it to answer in that case, because it'd fire off two answers. I'll be using databases for the future of it, all I was trying to figure out was the initial pattern. Specifically how to ignore a random length string. So for the last question I was hoping to have it ignore everything after the trigger fires from "Krazeth asks, '" and then have it answer based off the keywords I've established (or ignore).

Something like this would work best if you have a predefined activation message:

#TR {(%w) asks, "How do I get to (*)?"} {
#LOCAL $path
#IF (!%ismember($where, @bannedPlaces)) {$path=%pathfrom(, $where)}
#IF ($path) {answer $who Just go $path to get there} {answer $who Sorry, I can't help you with that}

You would need to populate @bannedPlaces manually to keep from giving directions to specific rooms on your map.
It works off of %roomname, or any optional keyword you may have entered in the 'short name' field of the room properties window (room text tab).

#TR {(%w) asks, "How do I get to (*)?"} {
#SWITCH (%2)
("Gregg's house") {answer Head east and take the third right, look for the blue house}
("Carnegie Hall") {answer You can't get there from here}
("my house") {answer I don't know where you live}
{answer Never heard of that place}

This way is a bit more work to set up the various answers but can seem a lot more personable, and you don't have to have mapped out the game world to use it.

I would suggest renaming your package files one at time to find which file is the problem. Once you have isolated the problem file you may want to retrieve data from it using something like Sqlite Browser. That can save you having to rewrite everything.
The only good questions are the ones we have never answered before.
