You have named the timer timerend how do this.

pawn Код:

forward timerend(playerid);
public timerend(playerid)
{
//sendclientmessage the public timerid is what happens when the timer is done
return 1;
}

When give a name to the timer.

pawn Код:

timerendA = SetTimerEx("timerend",6000,false,"i",3550);

Then you need to KillTimer OnPlayerEnterChecpoint KillTimer(timerendA);
