pawn Code:

At the top:

CMD:stunt(playerid, params[])
{
    GetPlayerPos(playerid, x, y, z);
    SetPlayerPos(playerid, -1114.1460, 378.5243, 14.1484);
    SetPlayerInterior(playerid, 0);
    SetPlayerVirtualWorld(playerid,12);
    SendClientMessage(playerid, -1,"Sekarang Anda Telah Memasuki /stunt");
    SetPVarInt(playerid, "inStunt", 1);
    return 1;
}

CMD:back(playerid, params[])
{
    SetPlayerVirtualWorld(playerid,0);
    SetPlayerPos(playerid, x, y, z); //Sets the players position to the position we saved in /stunt
    DeletePVar(playerid, "inStunt");
    return 1;
}

CMD:v(playerid, params[])
{
    new carId, Float:x, Float:y, Float:z;
    if(sscanf(params, "i", carId)) return SendClientMessage(playerid, -1, "Usage: /v carId");
    if(carId < 400 || carId > 611) return SendClientMessage(playerid, -1, "Invalid car Id, (400 - 611)");
    if(GetPVarInt(playerid, "inStunt") != 1) return SendClientMessage(playerid, -1, "anda harus berada di /stunt untuk menggunakan command ini!");
    GetPlayerPos(playerid, x, y, z);
    CreateVehicle(carId, x, y + 5, z, 0,-1, -1, -1);
    SetVehicleVirtualWorld(carID, 12); // I changed this line
    SendClientMessage(playerid, -1, "Car spawned at your location!");
    return 1;
}
