I'm not sure if key manipulation is possible in GSCs.
Wait, it is I think..
[php]self notify("F");
wait 0.1;
self notify("F");[/php]
Wait, that presses keys for you... lol
EDIT - Aaahhh, I know:
[php]
self.Countdowntime=3; //Change this to what you want the limit to be (seconds)
self waittil("F");
doTimer(self.Countdowntime);
self waittil("F");
if(self.Countdowntime <= 0)
{
self suicide(); //You can change what happens if you do it slow
} else {
//commands here
}
[/php]
