Skripta koju koristim: od 0
Detaljan opis problema: Pa na osnovu Makijevog tuta za posao kosac trave napravio ja za vozac nafte tj kamiondzija i sad prodjem prvi marker i tu ispise sve lepo utovaranje nafte itd zatim odem do drugog markera na kom bi trebalo da se istovari nafta a umesto toga uradi se ono sa 3. markera tj igrac dobije pare... U cemu gresim evo kodovi?
Dio skripte:
na vrhu

new naftakamion;

new VoziNaftu;

stock za ovo naftakamion tj za taj kamion vozaca nafte

stock NaftaKamion(carid)
{
	for(new i = 0; i < sizeof(naftakamion); i++)
	{
		if(carid == naftakamion)	return 1;
	}
	return 0;
}

Zatim idu OnPlayerEnterCheckpoint

new random_guza = 400+random(600);
new string1;
if(VoziNaftu == 1)
	{
		new idv = GetPlayerVehicleID(playerid);
	    if(NaftaKamion(idv))
	    {
	    if(IsTrailerAttachedToVehicle(GetPlayerVehicleID(playerid)))
	        {
			VoziNaftu = 2;
            DisablePlayerCheckpoint(playerid);
            SetPlayerCheckpoint(playerid,1613.1394,-1753.4520,13.2692, 5.0);
            TogglePlayerControllable(playerid, 0);
            SetTimerEx("Naftica",10000,false,"d",playerid);
            GameTextForPlayer(playerid, "Molimo pricekajte~n~da se nafta utovari...", 10000, 5);
			}
		}
	    return 1;
	}
if(VoziNaftu == 2)
	{
		new idv = GetPlayerVehicleID(playerid);
	    if(NaftaKamion(idv))
	    {
	    if(IsTrailerAttachedToVehicle(GetPlayerVehicleID(playerid)))
	        {
			VoziNaftu = 3;
            DisablePlayerCheckpoint(playerid);
            SetPlayerCheckpoint(playerid,2116.8909,907.6600,10.8203, 5.0);
            TogglePlayerControllable(playerid, 0);
            SetTimerEx("Nafticaa",10000,false,"d",playerid);
            GameTextForPlayer(playerid, "Molimo pricekajte~n~da se nafta istovari...", 10000, 5);
			}
		}
	    return 1;
	}

	    if(NaftaKamion(idv))
	    {
	    if(IsTrailerAttachedToVehicle(GetPlayerVehicleID(playerid)))
  			{

            DisablePlayerCheckpoint(playerid);
            SetPlayerCheckpoint(playerid,1599.6667,-1758.1912,13.8664, 5.0);
            GivePlayerMoney(playerid, random_guza);
            format(string1, sizeof(string1), "+$%d", random_guza);

			if(NaftaKamion(idv))
		    {
				SetVehicleToRespawn(idv);

	    return 1;
