You want to use a pattern like this. Basically, you are making a non-capturing group (the outer parentheses with the "?:" at the beginning of it), and inside that, you have an either or created by using the pipe character "|", so it will match EITHER nothing, because there are no...

If you have a script, but need help using it, surely if we are to offer suggestions, we will need to see what that script is first.

Oh, I forgot, you are also going to need to escape all those square brackets, so maybe something like this:
map prompt < HP %[ %d+/%d+ %] MV %[ %d+/%d+ %] Exits: %[ %a+ %] Room: .+ >

The problem is that you are giving it the pattern you would send to the game for it to show you what you are seeing, not a Lua string pattern that matches the text the game sends back. At a glance, I'd try doing this:
map prompt < HP [ %d+/%d+ ] MV [ %d+/%d+ ] Exits: [ %a+ ] Room: .+ >

Miniconsoles and transparency don't mix, sadly. You should, however, be able to set a background for your miniconsole to use. What code are you using to set the background for it?

Try this, all as one big trigger:
perl regex: you point at (.+) and
substring: ring
substring: glows
perl regex: (\w+)\.
[X] AND / Multi-line delta | value: 1

It should capture the name of the target in multimatches[1][2] and the color the ring glowed in multimatches[4][2].

So while I agree that it would be ideal to make databases work properly when using non-Latin characters for, if I'm understanding this correctly, the name of the database and its various field names, it should be possible to work around the language barrier for day to day use by creating a table wit...

There is definitely a system in place to allow for normal special exits, which go from one fixed room to another. But since this is dynamic in terms of where it sends you, it would be a bit more complicated. I'd say you have two main options. The first is to just rely on the script's built in locati...

So that rule and regex helps the case where someone has written a naked ampersand in the form of "You are standing at the intersection of Church St & University Road" but not in the case "You flick on the TV and see the closing credits to the Tom&Jerry show". It also doe...

So, from what I can find about MXP [https://www.zuggsoft.com/zmud/mxp.htm], it is modeled after XML, which has the following rules regarding entity usage: Rules for using legal Entity Markup The entity must be declared in the DTD. If you are using an XML document which is not validated against a DTD...
