Hello, I want my colour trigger to have a countdown timer so it does go off too many times in a row, say a 5 second wait.

The line to play the sound is:

PlaySound (0, IsSound, false, 0, 0)

I assume I want some kind of for statement beforehand with a timer, but I don't know where to start.
Thanks!

You can use the Lua function os.time to find the current time in seconds.

What I would do is store that in a global variable, in your trigger, if the variable is not already set. Something like this:


<triggers>
  <trigger
   enabled="y"
   match="foo"
   send_to="12"
   sequence="100"
  >
  <send>

-- if 10 seconds are up forget about when it last fired and zero the counter
if recentTimeTriggerFired then
  if os.difftime (os.time (), recentTimeTriggerFired) &gt;= 10 then
    timesTriggerNoticed = 0
  end -- if over 10 seconds since last time

  -- IF less than 5 seconds have elapsed
  -- AND it has fired more than 3 times
  -- THEN play the sound

  if os.difftime (os.time (), recentTimeTriggerFired) &lt;= 5 and
     timesTriggerNoticed &gt;= 3 then
     check (PlaySound (0, "tada.wav"))
     timesTriggerNoticed = 0
  end -- end of 3 times in a row with the most recent less than 5 seconds ago
end -- if it fired before

recentTimeTriggerFired = os.time ()
timesTriggerNoticed = (timesTriggerNoticed or 0) + 1

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

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