Ok so better word for what I was meaning is scriptings was used to create the triggers.... Am I correct on that?

Think of triggers as scripting on the fly. They do the same things, scripts are simply in a preset file that can't be directly edited once it's loaded by MC and in use by the client. Triggers are small bits of editable script you can change as your needs on the MU* change.

Oh, Nick, when you get around to checking in here again, I'm using 4.94 now (was 4.84) and still getting that error where it expects = near EnableTimer

Ahh I see, well I know nothing about scripting... i dont understand how a script for a trigger to be fired would be written, nothing of the sort, if someone could kindly point this nood in a good starting space to learn that would be great, so i can start putting scripts in to my mud to do the things i want....since I started this post I have been doing all sorts of reading, including reading from Nicks scripting guide...
*Sighs Greatly*
Would love to know more...

Ok, not sure what I've got wrong with this, documentation says it should work.


sleep
EnableTimer("manacheck", true)

...


wake
EnableTimer("manacheck", false)
else
break
endif

Where did "sleep" and "wake" come from? That's not documented anywhere. If they are function calls they need brackets, eg.


sleep ()

In this case, those are direct mud commands

ok that is where I am lost, how do I know what to set for a variable and how do I set it all up?

Watch those videos, it should become clearer.

You establish some "trigger" event, like something coming from the MUD.

When that happens you do stuff. It's hard to explain better, but you might say that if you see:


You are thirsty.

You make a trigger that notices that phrase and sends:


drink water

Now the devil is in the details. Maybe the message is not exactly "You are thirsty." and maybe that's not how you drink. But that's the basic idea.

Progress, at least a little bit - I found what was wrong with my sleep trigger. Turns out that mixing mud commands and script calls isn't quite as simple as I thought and I needed to use Send ("sleep") instead of just the command ... that's what happens when I stray out of my comfort zone, I have to learn new things lol.

Still tweaking the other half of the attempt at figuring out how to do this request, looking like it might not be workable off the prompt the way I tried to do it though. I'm thinking converting part of score to regex and working it that way might be a better option.

*edit* Yeah, def not firing on the prompt for this so back to the drawing board there.

The relevant line from score is

||||   Int:  17( 19)    Wis:  15( 18)   :   Mana:       133   /   133      ||||

The spacing I expect will always be like that, the numbers will of course be different.

My current attempt at converting that to a trigger is


<triggers>
  <trigger
   enabled="y"
   match="^\|\|\|\|   Int\:  *\( *\)    Wis\:  *\( *\)   \:   Mana\:       *   \/   *      \|\|\|\|$"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>current = %5
max = %6

if "current" == "max" then
Send ("wake")
EnableTimer("manacheck", FALSE)
end</send>
  </trigger>
</triggers>

Finished version of the out of mana trigger:


<triggers>
  <trigger
   enabled="y"
   match="You don't have enough mana."
   send_to="12"
   sequence="100"
  >
  <send>Send ("sleep")
EnableTimer("manacheck")</send>
  </trigger>
</triggers>

Ok I know how to set up triggers from that fire from the output the mud send but i cant figure out how to make this into a trigger.
Finished version of the out of mana trigger:


<triggers>
  <trigger
   enabled="y"
   match="You don't have enough mana."

  <send>Send ("sleep")

Copy from <triggers> to </triggers>, open the triggers menu in MC, hit paste. What you're seeing here is the raw xml that MC saves triggers and whatnot as. For what it's worth, my current manacheck timer is a 90 second score sent directly to the mud though the attempt to match on the line that has mana on it isn't quite right yet.

Yep, that's exactly how you'd handle that. You could also copy the enabletimer line and just change the name to add a 2nd timer.

So I was reading all sorts of things last night on scripting, this is scripting a trigger to add a timer, if someone could add more help on writing my own scripts this would become so much easier for me to understand... yes i know this is all in xml coding but it is still a script none the less...

If you asked more specific and detailed questions it would be much easier for us to offer suggestions. You have to help us help you by asking better questions.

As Nick suggested, watch the instructional videos.

Help me convert that line I posted earlier to a proper regex ;) I know the conversion I posted is wrong (solid foundation, bad numeric conversions) but I've always been horrible with regex conversions like that.

*edit*
It just occurred to me that converting that line to regex is only minimally necessary since it only needs to match on full mana and the stats won't change while sleeping. Provided there isn't a lot of gear changing going on, it should be possible to simply paste the line from score with full mana as the trigger to match to wake the sleeping caster and disable the associated timer. The only real benefit to the regex conversion at this point is not needing to change the trigger every time you gain a level or trade out a piece of gear that affects your mana pool.

A nice read is here:

Regular expressions

Regular expressions (as used in triggers and aliases) are documented on the Regular expression tips forum page.
Also see how Lua string matching patterns work, as documented on the Lua string.find page.


   match="^\|\|\|\|   Int\:  *\( *\)    Wis\:  *\( *\)   \:   Mana\:       *   \/   *      \|\|\|\|$"

OK, to match 4 x | symbols you can use:


\|{4}

To match multiple spaces where the exact count isn't critical, just do:

\s+

There were a number of things wrong with your regexp, and the code. This version works better:


<triggers>
  <trigger
   custom_colour="2"
   enabled="y"
   match="(?x) ^ \|{4} \s+ Int: \s+ \d+ \( \s* \d+ \) \s+ Wis: \s+ \d+ \( \s* \d+ \) \s+ : \s+ Mana: \s+ (\d+) \s+ / \s+ (\d+) \s+ \|{4} $"
   regexp="y"
   send_to="12"
   sequence="100"
  >
  <send>

current = tonumber ("%1")
max = tonumber ("%2")

if current &gt;= max then
  EnableTimer("manacheck", false)
end

</send>
  </trigger>
</triggers>

For advice on how to copy the above, and paste it into MUSHclient, please see Pasting XML.

I used the "extended" regexp syntax (?x) to allow me to put spaces between each main item.


^        --> start of line
\|{4}    --> 4 bars
\s*      --> zero or more spaces
\s+      --> one or more spaces
\d+      --> one or more digits
\(       --> literally a bracket
\)       --> literally a closing bracket
(\d+)    --> a "capture" group (capturing one or more digits)
$        --> end of line

You didn't have any capture groups. I have two so they become %1 and %2.

You shouldn't compare:


if "current" == "max" then

That will never be true. You mean:


if current == max then
