I think I have better way to do it:

Код:

public OnTrailerUpdate(playerid, vehicleid)
{
	for(new x, y = MAX_VEHICLES; x < y; x++)
	{
	    if(IsTrailerAttachedToVehicle(x) && GetVehicleTrailer(x) == vehicleid))
	    {
	        //trailer is attached
	        return 1;
	    }
	}
	//trailer not attached
	return 1;
}
