What i'm trying to do is query the map database to compare a saved room description to the room i'm currently in.
This is to make the mapper auto-find which room i've been kicked to after entering a room with mobs that randomly
kick you off the road.

For the first problem, try replacing %roomdesc with %quote(%roomdesc).

To list the exits from a room, use the %roomexit() function.

I'm not sure about the problem with autocapturing room descriptions starting with # or *. That could be a bug. As for making your #TAG trigger work better, have you checked whether your mud has a setting to turn off line wrapping? If it does, you can let Cmud do the linewrapping for you. This will make it a lot easier to capture long lines in other triggers too.

I tried the %quote() thingy now:

Hm. I'm not sure offhand what the problem is. But I have a question about your logic. You are doing a %mapquery based on %zonenum and %roomdesc. But those functions will return the value based on the room that the map _thinks_ you are in. If the map did not actually know you moved, %roomdesc will still show the description of the room the map still thinks you are in. So, your search logic won't work for finding your new room. You need to somehow capture the current room description and do the search based on that instead.

Do you actually store the mini-map in your room descriptions?

He does, and he's probably of the mind to leave them in there instead of editing the entire map. It will be simpler if he removes the minimap, but I fully understand how tedious that can be (I did it 3 or 4 times myself because I thought of new things to add to/fix the map).

This is just a test line, i wouldn't be using that exact one. I'm just trying to find some functions i can use to be able to get what i want.
So far i was thinking that i can "look" after i've been kicked, and match the desc that comes up to any room in the zone i'm in.
That would result in one room (or several if the exact same desc are in many rooms). I could check the exits from that or those rooms,
to see if any of them leads to the room i was in before the kick. I haven't thought this far ahead yet actually, becuase i don't even know
how to begin with identifying the room i've been kicked to. Normally i begin with something and then i go Idea

and find a solution.

Yes the mapper normally captures the whole description (except when there are special chars), and the minimap is part of it. So it is
automatically captured. Not all rooms in the mud has this minimap in the desc, but as it is now i've got about 3000 rooms with it.
I don't really feel like editing all those rooms Razz

And besides, i don't know if it would be able to match the desc i get when i type "look"
if it's not exactly the same as the one saved in the mapper.

Not "look", "#LOOK". #LOOK replaces the old description with the new description. The trick is in making sure CMud recognizes the proper text so that it doesn't replace old junk with new junk. Since you want to exclude things from the line, this is where #TAG triggers would come into play.

We can help you with the trigger part, so all you need to do is provide the proper examples and whatever code you may have been using.

Actually i mean "look" Very Happy

I meant to say that i send the "look" command to the mud to "look around in the room" and bring up the desc, exits and any mobs or players. Because that doesn't automatically show up when i get kicked out.
I have already saved to a var the ID of the room i was in before i go kicked, and i can then do something like this:
look -> identify new room with desc -> match rooms to the rooms adjacent to the original room -> determine the correct exit from the original room -> step map into the room i got kicked to
This way i can make the mapper follow to the room i got kicked to. It should always just be in follow mode.

I haven't yet written any code or made any triggers at all for this auto-relocate function, since i haven't even come up with a way to match the descriptions. That's why i'm just using the #show command to print it on the screen.

This is an example room:
It is the text i get from the mud when i give the command look.

Okay, I think you've described the situation pretty well at this point. Let's see...

I guess you are only using %roomdesc right now for testing? Because you will have to do something else to capture the results of your "look" command for your actual application, as I said above.

For the #TAG descpara triggers, you could rewrite all those different triggers into a single trigger.

Yea i'm just using those two #show lines to see the output. At the moment i'm not really thinking about the rest of the script since it all depends on getting this to work. It really should be a piece of cake to whip up the rest once this coconut is smashed.

I've tested all the special characters in Options>General>Scripting>Special Characters, and the ones that don't work for me are # ; @ % &
The rest works fine. And they're all standard ones i presume, cos i've never changed them.

I just typed in those characters in turn into the description of the room i was currently in, and those 5 characters made the queries fail.

About the #tag triggers, i'd rather avoid using them actually, atleast the way they are now. They only make the mapper capture the lines that begin with those chars, nothing else. Like this:

I didnt read to much past the first couple of posts so this the solution to that

Those are possibly special chars in sql for something so the easiest way to get past this would be to use double quotes instead of single quotes when building your query since you are looking for an exact match and don't need any of the fancy SQL shortcuts.

I created a room and teleported into it for testing

ROOMNAME: cccc+@cccc A stone covered road running from south to north.
ROOM DESc: cccc|#cccc
.ccc*cccc

#SHOW ROOM %mapquery(%concat("Zoneid='",%zonenum(),"' AND Name=",%char(34),%roomname,%char(34)))
#SHOW DESC %mapquery(%concat("Zoneid='",%zonenum(),"' AND DESC=",%char(34),%roomdesc,%char(34)))

ROOM 7437
DESC 7437

(Same triggers with the mapquery removed so you can see the query)
Zoneid='69' AND Name="cccc+@cccc A stone covered road running from south to north."
Zoneid='69' AND DESC="cccc|#cccc
.ccc*cccc"

Yes my brother was talking about some SQL stuff too before i posted here, i didn't really listen. Rolling Eyes

Those lines didn't work for me, i had to change them to:

#SHOW ROOM %mapquery(%concat("Zoneid=",%zonenum," AND Name=",%char(34),%roomname,%char(34)))
#SHOW DESC %mapquery(%concat("Zoneid=",%zonenum," AND DESC=",%char(34),%roomdesc,%char(34)))

Almost the same. i'm gonna play around with it some more and see what more can be done. But atleast now it works in the rooms where it didn't work before.

Now the only thing i'm still wondering about is how to set up the mapper to capture room descriptions with these special chars correctly Wink

But i think i'm gonna move that to a different thread since it doesn't have anything to do with the title.
Thanks everyone for the help!

Yes please use a second thread for the map captures. Also to help us out walk between 4 rooms or so and paste the output between code tags. This will allow us to see exactly how everything is formatted and exactly what happens when you walk between rooms, resulting in fewer frustrations between poster and postee in narrowing it down.
