It's best to use a timer for that (SetTimerEx("Killplayer", 1000, 0, "i", playerid))

pawn Код:

new Killcount[MAX_PLAYERS];

pawn Код:

if(!strcmp("/kill", cmdtext, true))
{
    Killcount[playerid] = 10; // 10 seconds
    SetTimerEx("KillPlayer", 1000, 0, "i", playerid); //Check every second for Killcount.
    new str[10]; format(str, 10, "%d...", Killcount[playerid]);
    SendClientMessage(playerid, -1, str);
    return 1;
}

pawn Код:

forward KillPlayer(playerid);
public KillPlayer(playerid)
{
    switch(Killcount[playerid])
    {
        case 0: return SetPlayerHealth(playerid, 0.0);
        default: 
        {
            SetTimerEx("KillPlayer", 1000, 0, "i", playerid);
            new str[10]; format(str, 10, "%d...", Killcount[playerid]);
            Killcount[playerid] -= 1;
            SendClientMessage(playerid, -1, str);
        }
    }
}
