Hello!

Try this:

PHP код:

public OnVehicleSirenStateChange(playerid,vehicleid,newstate)
{
    Siren[vehicleid] = CreateObject(19620,0,0,0,0,0,0,0);
    if(newstate == 1 && !IsACarWithSirenObject(vehicleid))
    {
        AttachObjectToVehicle(Siren[vehicleid],vehicleid,0.00,-0.549499,0.884999,0.0000,0.0000,0.0000);
        return 1;
    }
    else if(newstate == 0 && !IsACarWithSirenObject(vehicleid))
    {
        DestroyObject(Siren[vehicleid]);
    }
    return 1;
} 


If it doesn't work, what prints here?

PHP код:

public OnVehicleSirenStateChange(playerid,vehicleid,newstate)
{
    printf("vehicleid: %i - newstate: %i - Objekt-ID: %i",vehicleid,newstate,Siren[vehicleid]);
    Siren[vehicleid] = CreateObject(19620,0,0,0,0,0,0,0);
    if(newstate == 1 && !IsACarWithSirenObject(vehicleid))
    {
        print("newstate == 1");
        AttachObjectToVehicle(Siren[vehicleid],vehicleid,0.00,-0.549499,0.884999,0.0000,0.0000,0.0000);
        return 1;
    }
    else if(newstate == 0 && !IsACarWithSirenObject(vehicleid))
    {
        print("newstate == 0");
        DestroyObject(Siren[vehicleid]);
    }
    return 1;
}
