I think you only need to check this ($2 == $null)
If there is a $2, there is a $1 too :D

Okay
Thanks :D

Name your timer : timerspam 0 $1 ...
To stop him /.timerspam off

how can we halt and stop a timer 0 ?

At what level?
Your code is just but lines 10 your color code is stuck on $2-

.timer 1 $calc(%n *2) msg $1 $2- 

What does not allow the sending of the text

kiri, you've lost me there.

Jethro your code is correct but you pasted color-code $2-

here's what I'll do :
//spam notice $me 2 10 5 test

alias spam {
  if !$1 || !$2 || !$3 || !$4 || !$5 || !$6 || !$regex($1,/(msg|notice)/i) || $3 !isnum || $4 !isnum || $5 !isnum { echo -at Syntax : /spam <msg|notice> <nick,nicks,...> <number of lines> <how often repeat on the same line>  <all the time x> <text> }
  else {
    $+($chr(46),$1) $2 You will be spammed all the $duration($5)
    var %n = 1, %n1 = $3
    while (%n <= %n1) {
      .timer 1 $5 $+($chr(46),$1) $2 $str($$6- $+ $chr(32) , $+ $4 $+ )
      inc %n
    }
  }
}

the code is not specifically optimized but it shows the possibilities in a few lines
can be used a $istok instead of regex ( !$istok(msg.notice,$1,46) )
what is practical is done you can send your message to several people <nick1,nick2,..>

Uhm! Getting confused now. What should i do now??
I was thinking to make a /write command instead that will auto-load the new script as per the trigger loop.

If you figure the 2-second delayed spam is not consider spamming per se, you may remove the timer and change it back to your original warning message in the beginning.

Suggestion:

alias spam {
  if (!$1) || (!$2) {
    echo -at Syntax : /spam <nick> <word/phrase> 
  }
  else { 
    msg $1 You will be spammed every 2 seconds...
    echo -at Mass Spammer Activated! Target : $1 Spammed with : $2- 9,1Spam Meter : 16
    var %n = 1
    while (%n <= 16) {
      .timer 1 $calc(%n *2) msg $1 $2- 
      inc %n
    }
  }
}

EDIT - I made a minor mistake earlier.

An infinite timer would be more suiting. For example: "//timer 0 1" would send one command every one second(s) and so on. The "0" in the timer means that it will never end; it simply repeats the command every allotted amount of seconds, which in the example would be "1" second. That being said, be careful using such snippets, it could potentially attract unwanted attention.

Alias spam { .timer 0 $1 msg $2 $3- }

Trigger: /spam SECONDS TARGET MESSAGE
To turn off: /timersoff (I think, I can never remember the timer kill switch.)

Aha2y : I don't know how to set the loops but yes i can find a way out to set it. i will set a writing parameter for that.

Thanks dazboy xD

What about a WHILE LOOP, So you can do /spam ?

Works and its brilliant xD
