I wrote a plugin to keep track of my affects but have some difficulties with a timer to check my variables:


<!--  Timers  -->

<timers>
  <timer enabled="y" second="1.00" send_to="12">
    <send>
	InfoBackground ("black")
	InfoClear ()
	if string.find(GetPluginVariable ('f9e3698e93e4ac3786236acf', 'prio1'),"^=") == nil then
		InfoColour("green")
		Info (GetPluginVariable ('f9e3698e93e4ac3786236acf', 'prio1'))
	else
		InfoColour("red")
		Info (GetPluginVariable ('f9e3698e93e4ac3786236acf', 'prio1'))
	end
    </send>

  </timer>
</timers>


If the variable named "prio1" starts with a = (e.g "= fly down =")then it should colour it green and otherwise red.

Is there maybe a problem with the "if"?

You have it backwards. The test for "== nil" will be true if the condition does *not* match.

Ah thats just a typo in my explanation, the problem was somewhere else (the "send to" part of my triggers were wrong).

Thanks anyway :)

I decided to redo my plugin to make it easier to adopt to other characters. So I tried to move the trigger conditions into variables but somehow it stoped working. I didnt get any compile errors so I guess its a problem with the matching text or the variables.



  <variable name="prio1spell">co 'armor of thorns'</variable>
  <variable name="prio1downmessage">Your armor of thorns disappears.</variable>
  <variable name="prio1upmessage">Thorns sprout from your skin as you undergo metamorphosis.</variable>
  <variable name="prio1do"> =armor= </variable>
  <variable name="prio1up">  armor  </variable>
  <variable name="prio1current"> =armor= </variable>




  <trigger
   enabled="y"
   match="GetPluginVariable ('f9e3698e93e4ac3786236acf', 'prio1upmessage')"
   name="p1up"
   sequence="100"
   send_to="12"
  >
   <send>
    SetVariable ("prio1current", GetPluginVariable ('f9e3698e93e4ac3786236acf', 'prio1up'))
   </send>
  </trigger>


Any idea what went wrong?

What, exactly, are you attempting to match?

That won't work. You can't put a script function in as the match string. That would literally match what you typed there.

If the plugin is the one you are currently running (ie. you are not trying to get a variable from a different plugin), all you have to do is:


 match="@prio1upmessage"


... and check "expand variables".

The string:
"Thorns sprout from your skin as you undergo metamorphosis."
I put into the variable named 'prio1upmessage'

I decided to redo my plugin to use miniwindows instead of the infobar but somehow I got some trigger problems again...
I trimmed the code down to one spell to make it less verbose.


The triggers on the prio1up and prio1down triggers work it seems but the triggers on the affects command: 


You are affected by:
Spell: 'desensitize' for a short time.
Spell: 'fly' for a very short time.
Spell: 'ocular enhancement' for a short time.
Spell: 'ocular enhancement' for a short time.
Spell: 'ocular enhancement' for a short time.
Spell: 'invis' for a medium time.


Seem not to work at all.
Neither the trigger on "You are affected by" nor the prio1affectregex I used.

Any ideas or is there a way to debug plugins? The regex seem to work but some bug must be in there. :/

...

You are affected by:


They aren't the same. You need to match on "You are affected by:" and maybe there is a trailing space. You need to carefully check trigger matches.

Try turning on Game menu -> Trace to see what is matching.



This is too complex and confusing:


SetVariable ("prio1current", GetPluginVariable ('f9e3698e93e4ac3786236acf', 'prio1do'))


This plugin is ID "f9e3698e93e4ac3786236acf", right?

So just write:


SetVariable ("prio1current", GetVariable ('prio1do'))

As for the other triggers, I overlooked something in my earlier answer. You can indeed do something like this:


match="@prio1upmessage"


However, MUSHclient helpfully "escapes" any special characters inside the match text so the regular expression matcher doesn't get confused. However if you deliberately put a regular expression there, you need to add a "!" like this:


match="@!prio1upmessage"


When I do that, and with Trace on, I see this:


You are affected by:
Spell: 'desensitize' for a short time.
TRACE: Matched trigger p1stat
Spell: 'fly' for a very short time.

Wow, that fixed all problems! :D
Also found another typo thanks to trace, will remember using that next time.

Thanks a lot!

It never ends...

I tried to add a scrip function to my plugin that creates a list of missing spells according to priority and casts the highest one on the press of a button.



<!--   Script  -->

<script>
<![CDATA[
function OnHelp (sName, sLine, wildcards)
  World.Note (World.GetPluginInfo (World.GetPluginID, 3))
end



function CastAll ()
  ArrayCreate "spells"
  ArrayClear "spells"
  
  if string.find(GetVariable ('prio1current'),"=") ~= nil then
	ArraySet ("spells", 1, GetVariable ('prio1spell'))
  end            


  if string.find(GetVariable ('prio2current'),"=") ~= nil then
	ArraySet ("spells", 2, GetVariable ('prio2spell'))
  end            


  if string.find(GetVariable ('prio3current'),"=") ~= nil then
	ArraySet ("spells", 3, GetVariable ('prio3spell'))
  end            
  
  CastFirst(spells)

end

function CastFirst (spells)
	if (ArrayGetFirstKey ("spells") ~= nil) then
		return ArrayGetFirstKey ("spells"))
	else
		return ""
	end	
end		



]]>
</script>



But for some reason I get an error message when I try to load the script looking like this:


Compile error
Plugin: Spellup_Script (called from world: Carrion Fields)
Immediate execution
[string "Plugin"]:72: 'end' expected (to close 'if' at line 71) near ')'
Error context in script:
  68 : end
  69 : 
  70 : function CastFirst (spells)
  71 :  if (ArrayGetFirstKey ("spells") ~= nil) then
  72*:   return ArrayGetFirstKey ("spells"))
  73 :  else
  74 :   return ""
  75 :  end 
  76 : end



I was checking Lua tutorials and the like but
if (something) then
something
else
something
end

should be correct syntax...

Is it a problem that I decided to put it in the existing <script> tag?

You have an extra close paren on the return line.
