http://pastebin.com/ELS7ge60I found this.. it's a script that checks if a stream is online or not. So.. it is made so that it triggers from a text event but since it uses an alias you can use it on your own.
Put the code from pastebin in a clean remote and then put this code too.
on *:start: {
.timercheckstream 0 25 twitch_stream Nick #SomeChannel SomeStream
}
on *:text:*:#: {
if ($strip($1) == !stopcheck) {
.timercheckstream off
}
elseif ($strip($1) == !startcheck) {
if ($timer(checkstream)) {
msg $chan Automated Checking Is Already ON.
}
elseif (!$timer(checkstream)) {
.timercheckstream 0 25 twitch_stream Nick #SomeChannel SomeStream
}
}
}
In the pastebin script the first parameter of the alias is $nick which is the person that triggered the text event. Since what i gave you will start checking automatically when mIRC starts you can use your nick on twitch.So replace Nick with your nick or whatever other word you want, #Somechannel with your channel and SomeStream with your stream name. I'm sure it will work, the scripter of this is pro
Good Luck!
NOTE: You'll have to restart mirc for it to start or just use the text command !startcheck
