| Hi all, my second question since I registered!
I have the following line I want to trigger on
You sense a connection between room1 and room2.
The problem is that room1 and room2 may contain multiply words, and the expression may extend over multiply lines...so for a more specific example:
You sense a connection between Twisted path past a dwarf tree (house) and
Gemstone vials of Moghedu.
or
You sense a connection between Southern Balcony (house) and River Zaphar
through forest.
Is there anyway to match this, or am I being to hopefull?
Thanks! | | Top |

| The simplest thing is a multi-line trigger, which are notorious to get right, because of the possibility of multiple matches. This seemed to work for me from your examples:
<triggers>
<trigger
enabled="y"
lines_to_match="3"
match="(?s)^You sense a connection between ([^.]+) and ([^.]+)\.\Z"
multi_line="y"
regexp="y"
send_to="2"
sequence="100"
>
<send>Wildcard 1 = %1
Wildcard 2 = %2</send>
</trigger>
</triggers>
The wildcards may end up with newlines in them (because the text had a line break) but you can do a replace to get rid of those.
Example:
You sense a connection between Southern Balcony (house) and River Zaphar
through forest.
Wildcard 1 = Southern Balcony (house)
Wildcard 2 = River Zaphar
through forest
This matched OK, now by replacing the newlines by spaces in the wildcard you would get the room name without breaks in it.

| Thanks for that.
One last question...if I create a trigger with a certain name, and then attempt to make another with the same name, will it overwrite the original one, cause me to have two triggers, or not create the second one?

| Using the GUI interface, or a script, you can't add a trigger of the same name, *unless* (in a script) you use the flag:
const eReplace = 1024 ' replace existing trigger of same name
