pawn Код:

public OnTrailerUpdate(playerid, vehicleid)
{
      Trailer[vehicleid] = GetVehicleTrailer(vehicleid);
      return 1;
}

public OnPlayerUpdate(playerid)
{
      new vehicleid = GetPlayerVehicleID(playerid);
      if(IsPlayerInAnyVehicle(playerid) && !IsTrailerAttachedToVehicle(vehicleid))
      {
          if(Trailer[vehicleid] != INVALID_PLAYER_ID)
          {
                 CallLocalFunction("OnTrailerDetach", "id", playerid, vehicleid, Trailer[vehicleid]);
                 Trailer[vehicleid] = INVALID_VEHICLE_ID;
                 return true;
          }
     }
     return true;
}

Then you can:

pawn Код:

public OnTrailerDetach(playerid, vehicleid, trailer)
{
       DestroyVehicle(trailer);
       return 1;
}
