You have a lot of duplication. I would move the repeated stuff into another function:


function draw_the_bars ()
  local hp_percent = hp / max_hp
  local sp_percent = sp / max_sp
  local ep_percent = ep / max_ep

  -- fill entire box to clear it
  check (WindowRectOp (win, 2, 0, 0, 0, 0, BACKGROUND_COLOUR))  -- fill entire box
  
  -- Edge around box rectangle
  check (WindowCircleOp (win, 3, 0, 0, 0, 0, BORDER_COLOUR, 0, 2, 0, 1))

  vertical = 6  -- pixel to start at

  DoGauge ("HP: ", hp_percent,  ColourNameToRGB "darkgreen")
  DoGauge ("SP: ", sp_percent,  ColourNameToRGB "mediumblue")
  DoGauge ("EP: ", ep_percent,  ColourNameToRGB "gold")

  WindowShow (win, true)

end -- draw_the_bars

function do_prompt (name, line, wildcards)

  hp, max_hp = tonumber (wildcards [1]), tonumber (wildcards [2])
  sp, max_sp = tonumber (wildcards [3]), tonumber (wildcards [4])
  ep, max_ep = tonumber (wildcards [5]), tonumber (wildcards [6])
    
  draw_the_bars ()
  
end -- do_prompt 

function do_prompt2 (name, line, wildcards)

  hp = tonumber (wildcards [1])
  sp = tonumber (wildcards [2])
  ep = tonumber (wildcards [3])

  draw_the_bars ()
      
end -- do_prompt2


The font stuff looks OK. Why not test it and see?

Can you post the prompts that are coming through? Sounds like the trigger is matching but it is getting a low figure. You could add some debugging like this:


function DoGauge (sPrompt, current, max, Colour)


-- add this:

print ("In DoGauge, prompt=", sPrompt, "current=", current,
          "max=", max)



That might clarify what it is doing.

edit: the triggers section

edit 2: more testing!


HP:204/204  SP:272/272  EP:151/155
In DoGauge, prompt= HP:  current= 1 max= 25600
In DoGauge, prompt= SP:  current= 1 max= 13434880
In DoGauge, prompt= EP:  current= 0.9741935483871 max= 55295


It seems to be grabbing the fraction, rather than the min and max, for whatever reason. I haven't changed the triggers at all though... why would it do that?

Well let's see now ...


function DoGauge (sPrompt, current, max, Colour)


That is expecting 4 arguments.

You are sending it:


DoGauge ("HP: ", hp_percent,  ColourNameToRGB "darkgreen")


That's 3 arguments, including the colour code.

So, current will be 204/204 (that is, 1) and ColourNameToRGB ("darkgreen") gives 25600, so that's where the figures come from.

Did you change the way you called DoGauge?

aha, that's it. A few posts back you suggested a different way to do the two prompts, with the combined section as draw_the_bars (). That's where it got changed. I'll switch it and see if that fixes it. The switchup happened when I used the older version of the plugin at first, I think. I didn't update it all like I should have for the newer version.

Fixed :D


function draw_the_bars ()

  -- fill entire box to clear it
  check (WindowRectOp (win, 2, 0, 0, 0, 0, BACKGROUND_COLOUR))  -- fill entire box
  
  -- Edge around box rectangle
  check (WindowCircleOp (win, 3, 0, 0, 0, 0, BORDER_COLOUR, 0, 2, 0, 1))

  vertical = 6  -- pixel to start at

  DoGauge ("HP: ",  hp,  max_hp,  ColourNameToRGB "darkgreen")
  DoGauge ("SP: ",  sp,  max_sp,  ColourNameToRGB "mediumblue")
  DoGauge ("EP: ",  ep,  max_ep,  ColourNameToRGB "gold")

  WindowShow (win, true)

so here goes, I've NEVER coded at all in my life, i just did some editing earlier on the chat box window. Got it working for my MUD Atlas. i'm experienced with triggers. But heres my question

my prompt
[116/116hp|122/122mp|100/100mv] and sometimes has

[Bellrog 98%][116/116hp|122/122mp|100/100mv]
to show me what my party members health is. this will disappear if the person is at 100% being replaced with My name
[Dragonrider 100%][116/116hp|122/122mp|100/100mv]



Okay i need to get MY stats on a health bar, I don't know what part of the script i need to use, so if you could just edit the script with my information so all i have to do is copy and paste i would be most grateful!
Would be nice if above this bar it would put the party members health in normal text [Bellrog 98%] where bellrog is a wildcard *

I'm very new, and its like learning a foreign language, Any help would be amazing, specially to you Nick, I'm 25 and have been mudding since i was 12. I have used mushclient for many years and I will never change to another client. Please help! =)

Those extra brackets threw out the wildcard numbers. When I checked them I got:


1 
2 116
3 116
4 122
5 122
6 100


Wildcard 1 was empty.

Either change the regexp to:


^.*?\[(.*?)\/(.*?)hp\|(.*?)\/(.*?)mp\|(.*?)\/(.*?)mv\]$


OR change the code in the plugin to read:


local hp, max_hp = tonumber (wildcards [2]), tonumber (wildcards [3])
local mana, max_mana = tonumber (wildcards [4]), tonumber (wildcards [5])
local move, max_move = tonumber (wildcards [6]), tonumber (wildcards [7])


(I added 1 to each wildcard number).

and if i wanted to do a different prompt from a different character on the same plugin, i just add another trigger right? or would i have to change more again :(
[358/358hp|247/247mp]
would be the secondary prompt
regular expression would be
^\[(.*?)\/(.*?)hp\|(.*?)\/(.*?)mp\]$



How would I incorperate that? so it works for both?

And i tried both of those suggestions, and nothing... :(





-----I retract this statement, It is working for the first prompt, is it possible to make it match for a second one? or should i just make a separate plugin for each characters prompt?
