Hello,

I'm trying to make two highlights in 'one'.

This is the text from the MUD:

Your ouroboros senses Varek, Initiate of the Sanguine at Starlit Ritual Room, on a health of 324 and a mana of 285.

So I made a trigger that looks like this:
<triggers>
<trigger
custom_colour="7"
enabled="y"
ignore_case="y"
keep_evaluating="y"
match="\bYour ouroboros senses .+? at\b"
regexp="y"
sequence="90"
>
</trigger>
</triggers>

What I'd like to do is that get the name, inbetween 'Your ouroboros senses' and 'at' highlighted aswell, but in a different colour. It took med about 30 minutes just to get that simple trigger working, so...not all to handy with this. Is this possible to do?

Try this:


<triggers>
  <trigger
   custom_colour="7"
   enabled="y"
   ignore_case="y"
   keep_evaluating="y"
   match="\bYour ouroboros senses\b"
   regexp="y"
   sequence="90"
  >
  </trigger>

  <trigger
   custom_colour="3"
   enabled="y"
   ignore_case="y"
   keep_evaluating="y"
   match="(?&lt;=\bYour ouroboros senses\b).+?(?=\bat\b)"
   regexp="y"
   sequence="90"
  >
  </trigger>
</triggers>

The first trigger is sort-of what you had. The second one uses a "lookbehind assertion" to check that we have "Your ouroboros senses" *however* an assertion does not becomes part of the matched text, and is thus not coloured. The word "at" is then part of a "lookahead assertion" which anchors the colouring to finish at the word "at".

Thanks a lot, works perfectly and that piece of regexp makes me understand a bit more about it. Wonderful!
