[Threshold]

You would need to assign the timer to a variable in order to kill it.

Example:

pawn Код:

new MyTimer; //At the top of your script.

public OnGameModeInit()
{
    MyTimer = SetTimerEx("LooseHealth", 3000, true, "i", playerid);
    //OTher stuff...
    return 1;
}

//Where you want to kill the timer...
KillTimer(MyTimer);
//Other stuff...
