You need to define the valid vehicle ID. Here I did it for you.

pawn Код:

if (strcmp(cmdtext, "/miniguncar", true) == 0){
    if(GetPlayerVehicleID(playerid) == 362)
    {
        new weapona = CreateObject(362,0,0,-1000,0,0,0,100);
        AttachObjectToVehicle(weapona, GetPlayerVehicleID(playerid), -0.899999,1.500000,0.000000,-405.000488,-56.700008,1.000000);
        new weaponb = CreateObject(362,0,0,-1000,0,0,0,100);
        AttachObjectToVehicle(weaponb, GetPlayerVehicleID(playerid), 0.524999,1.500000,0.000000,-405.000488,-56.700008,1.000000);
        return 1;
    }
    else {
        SendClientMessage(player, COLOR_PINK, "You can only spawn the minigun weapons at a NRG Bike.");
        return 0;
    }
    
}
