weird thing concerning variables and timers

am trying to do this delayed on join message
it's not working, i get $chan not defined
i did it in other ways but i bumped into another prob
with is if 2 users join within less than 10 seconds
the last to join gets messaged twice
any one can help with that?

Code: Select all

bind join - * join_am


proc join_am { nick host hand chan rest } {

utimer 10 {
      if {![isop $nick $chan] && $nick != "xx" && $nick != "yy"   } { 
      	if {((![isbotnick $nick]) && (![isbotnick [hand2nick $hand $chan]]))} {
         if {(([onchan $nick $chan]) && ("[getchanhost $nick $chan]" == "$host"))  || (![isop $nick $chan])} {
            # They still have the nick they joined with.
            putserv "PRIVMSG [hand2nick $hand $chan] :Hi, Please \002DO NOT REPLY\002: just checking if you are infected."
		
         } elseif {((![onchan $nick $chan]) && ([handonchan $hand $chan]) || (![isop [hand2nick $hand $chan] $chan])))} {
            # They most likely changed nicks after joining.
            putserv "PRIVMSG [hand2nick $hand $chan] :Hi, Please \002DO NOT REPLY\002: just checking if you are infected."
    
         }
      }
   }
   }
}

The code passed to utimer is executed in the global namespace, so to avoid name conflicts and polluting the global namespace you should create a second proc that you invoke from the timer...

Code: Select all

bind join - * join_am
proc join_am {nick host hand chan} {
	utimer 10 [list join_am2 $nick $host $hand $chan]
}
proc join_am2 {nick host hand chan} {
	# add all that other code here
}
