Ok so i tried it and it didnt work either...
But Here ill show you my old timer:
on *:TEXT:!timedmsg1*:#: {
if ($nick isop $chan) && ($2) {
.timer1 0 $2 /msg $chan $3-
msg # your timer was added.
}
}
Basically it was used like this !timedmsg1 300 message here...
But Plenty times nobody was talking and he kept on spamming that message until the point it became annoying.
Adding something to make it like do it unless nobody has talked in the past 10 seconds would be pretty useful
