Help! How to make a colour-matching trigger

I want to make a colour-matching trigger,but the colour is not in the 8 options (Black ,Red,Green,Yellow,blue,Magenta,cyan,white).How do I.
And how can I get the colour code from mud.

The colour -should- be in the list. If it isn't, that is most likely because you have the bold representation of some colour changed to what you know it as. Look at Configuration -> Appaerance -> ANSI Colour for all the supported colours. If you find the colour you are looking for is indeed one of the bold colours, just select the appropriate colour in your trigger and make sure the checkmark for bold is black on white, rather than the default dark gray on a lighter grey (which signifies either is allowed).

If that doesn't solve it, we probably need some more information. Probably your mud is using MXP then, and I'm not entirely sure how to help you with that.

I do as you said,it still can't work . I try to copy the line which I want to match as HTML,it shows the background colour is "#800000",how can I do to match this background colour.

That tells me nothing, actually.

Can you select Edit -> Debug Packets, have the mud produce the line in question (and then deselect the option again to turn it off)? I'd like to see the precise data in question so I know what I'm dealing with.

Select the word in question, then go to Display -> Text Attributes. That shows the name of the colour it is in.

It's a maze map. The debug information :

I do as Nick Gammon says,the text attributes are:
letter:
text: White
Background: Red
Custom: n/a

RGB colour
text: #FFFFFF
Background: #800000

I make a trigger as follows
<triggers>
<trigger
back_colour="9"
enabled="y"
keep_evaluating="y"
match=".*"
match_back_colour="y"
match_text_colour="y"
regexp="y"
sequence="100"
text_colour="15"
>
<send>haha</send>
</trigger>
</triggers>
but it does not work.why?

In trying out your test data I find that the red square is not the first character in a line.

The help for "edit trigger" says:


The first character of the matching text is checked for the specified colour.


Thus it doesn't match (the first character is white on black).

See http://mushclient.com/faq point 33. There it discusses how you might check for the colour of each character.

In particular see this thread: http://mushclient.com/forum/?id=7818

What you would need to do, when you know you have the map line, is use the ideas discussed in that thread, and then check each character, to see if there is the correct colour combination in a particular part of the line.

Thanks for Nick Gammon's help!
I read the article you given. There's a fourth argument to a function called by a trigger. I try it in Jscript because I don't know Lua language, but failed. Is the fourth argument only supported by function in Lua?

Aye. The styles argument is only supported in Lua due to technical limitations in the Windows Script Host. I think there's a function GetLineStyleInfo() though.

Slight derail for Nick Gammon's eyes: I've suggested before to make the third parameter mandatory for plugins that have the version higher than whatever version introduces that.

Eg.. suppose this version were to be 4.50, then the trigger matching code would go like this for non-Lua scripts in versions 4.50 and above (pseudo code):

if trigger or alias matches then
  
  ...
  
  if script attached then
    if plugin_version >= 4.50 then
      CallScriptFunction(function, name, line, wildcards, styles)
    else
      -- old default behaviour
      CallScriptFunction(function, name, line, wildcards)
    end
  end
  
  ...
  
end


That way you could preserve and support old plugins until they are updated.
