My mud doesn't have hp/maxhp moves/maxmoves in the prompt line so I created one

In the mud I play the prompt line doesn't allow you to see your current health/max health current movement/max movement and that always bugged me. So, with about 2 hours of forum searching, examples here and there, I got this to work. Sort of...

Original prompt:
57H 122V 1596X 23C Exits:D> -- looks ugly

New prompt:
76/76H 122/122V 3727X 21C Exits:D -- much prettier

How I did it:
Into my scriptfile.lua goes:


function myprompt_line (name, line, wildcards)
  ColourNote ("white", "black", wildcards.health .. "/" .. GetVariable("maxhealth") .. 
                       "H " .. wildcards.moves .. "/" .. GetVariable("maxmoves") .. 
                                "V " .. wildcards.exp .. "X " .. wildcards.coins .. "C "
                                                  .. wildcards.other)
 end

Triggers:

<triggers>
  <trigger
   enabled="y"
   expand_variables="y"
   group="Prompt_Line"
   keep_evaluating="y"
   match="(?P&lt;health&gt;\d+)H (?P&lt;moves&gt;\d+)V (?P&lt;exp&gt;\d+)X (?P&lt;coins&gt;\d+)C (?P&lt;other&gt;.*?)\&gt;$"
   omit_from_output="y"
   regexp="y"
   script="myprompt_line"
   send_to="12"
   sequence="100"
  >
  </trigger>
</triggers>
<triggers>
  <trigger
   enabled="y"
   expand_variables="y"
   group="Prompt_Line"
   match="^You have (\d+)\((\d+)\) hit and (\d+)\((\d+)\) movement points\.$"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>SetVariable("maxhealth", "%2")
SetVariable("maxmoves", "%4")
ColourNote("silver", "blue", "Maximum health and movement defined")
</send>
  </trigger>
</triggers>

On my mud when you type 'score' you will get a line like: "You have 70(76) hit and 120(122) movement points." So for every time I hit score I'm defining max health/moves for myprompt_line function.

The problems:
In the 2nd trigger I posted I wanted to delay the ColourNote 2 seconds, but I couldn't figure out how to do that with DoAfter.

The bigger problem, though, is manipulating the 'new' prompt line. If I want to have the hp change color depending on the % of health left I'm not quite sure if I can do it since the prompt line is now a colournote(not coming from the mud) and I can't use triggers.
Anyway, I had fun trying to get this thing to work even if it took me almost 2 hours. :)

I edited your post to add [code] tags to make the script more readable.

You want DoAfterSpecial - this lets you script something after a few seconds.

http://www.gammon.com.au/scripts/doc.php?function=DoAfterSpecial

For example:



DoAfterSpecial (2, 'ColourNote ("white", "red", "hi there")', 12)

I am making use of the fact that Lua lets you mix quotes here - the single quotes are around the entire ColourNote statement - the double quotes are part of the ColourNote.

This does the ColourNote 2 seconds later. The 12 is "send to script".

So in your case the line in your second trigger could look like this:


DoAfterSpecial (2,   -- after 2 seconds
                'ColourNote ("silver", "blue", "Maximum health and movement defined")', -- do this
                12)  -- send to script

That is easy. In the function myprompt_line instead of one big ColourNote do some ColourTell calls followed by Note. You know the figures, choose the colours appropriately.

To illustrate, although you need to do the calculations:


-- health

local percent_health = wildcards.health / GetVariable("maxhealth") * 100
local health_colour 

if percent_health < 10 then
  health_colour = "red"
elseif percent_health < 50 then
  health_colour = "orange"
else 
  health_colour = "black"
end -- if

ColourTell ("white", health_colour, 
            wildcards.health .. "/" .. GetVariable("maxhealth") .. "H ")

-- similar for moves and experience

Note ""   -- wrap up line

thanks. works great now. everything does.
(except multi-line triggers with getlines)

Another question on this:

Is it possible to change certain words which are in a named wildcard?

example:

76/76H 96/122V 1800X 58C Exits:D> - here it looks great.

but when I enter combat I get more information:

76/76H 103/122V 3170X 96C [me:Perfect] [a large fly:Awful] Exits:NS

My ColourNote is:

ColourTell ("white", health_colour,
wildcards.health .. "/" .. GetVariable("maxhealth") .. "H ")
ColourTell ("white", moves_colour,
wildcards.moves .. "/" .. GetVariable("maxmoves") .. "V ")
ColourTell ("white", "black", wildcards.exp .. "X " .. wildcards.coins .. "C "
.. wildcards.other)
Note ""

So the 'certain' words like, 'Perfect', 'Awful', etc are contained in wildcards.other.

I can't think of any way to highlight specific words contained in wildcards.others. Is it possible to do?

thanks

Ok if this is your normal prompt, and the 2nd one is the battle prompt (I appended a '>' to the end to keep the formatting of the normal prompt, in case u missed that)

57H 122V 1596X 23C Exits:D>

57H 122V 1596X 23C [me:Perfect] [a large fly:Awful] Exits:NS>

a trigger like this SHOULD work ...


^(?P&lt;health&gt;\d+)H (?P&lt;moves&gt;\d+)V (?P&lt;exp&gt;\d+)X (?P&lt;coins&gt;\d+)C (?:\[me\:(?P&lt;selfstatus&gt;.*)\] \[(?P&lt;enemyname&gt;.*)\:(?P&lt;enemystatus&gt;.*)\]\s)?(Exits\:(?P&lt;exits&gt;.*)\&gt;)$

THEN you can do a check for "selfstatus" and "enemystatus" and compare them to whatever possible value/color combinations you want, then go from there, and if it does not match ANY in your list, then do not display them, cause it is an optional non-capturing section for the ENTIRE status output, but the status' as well as the mobname are all captured :)

Hope this is a decent push in the proper direction :)
I am not a master of RegExp, but can ALWAYS make them work, maybe not as efficiently as possible but it works :)

Laterzzz,

ah thanks

?: captures both instances. I tested with prints.

I'm having a hard time getting it to do what I want though. Probably because I'm not using the proper syntax.

I -think- what I can do now is put all possible values for selfstatus into a variable and then check to see if that variable matches the selfstatus wildcard or it's nil. If it's nil then use 1 set of colortells if not then use the other.

To illustrate with a slightly simpler example (one that doesn't have the named wildcards), this will match your case:



^(\d+)H (\d+)V (\d+)X (\d+)C (\[me:(.*?)\] ){0,1}(\[(.*?):(.*?)\] ){0,1}Exits:(.*)>

What we do here to optionally capture something like:



[me:Perfect]

... is to put the whole thing into an optional group, like this:



(\[me:(.*?)\] ){0,1}

The {0,1} at the end (or you could just put a ?) says the entire thing between the round brackets is optional.

I've learned quite a bit of regexp by doing this prompt line.

Question: Is it possible to capture the colors of a string?

example:

57H 122V 1596X 23C [me:Perfect] [a large fly:Fair] Exits:NS>

57H 122V 1596X 23C [me:Perfect] [a large fly:Fair] Exits:NS>

Both strings identical but depending on the % of health left on 'a large fly' Fair can be 2 different colors.

And a follow-up to that question is: Can I incorporate that into my prompt line script. Although, I'm sure that if it's possible to capture color it's manageable one way or another.

Thx
