X-Plane UDP interpreter - Delphi Unit (DCU)

X-Plane UDP Interpreter consists in a Delphi Compiled Unit (DCU) for Delphi 7 and/or B.D.S 2006 that interprets all Data packets received by a simple UDP Server (i.e. Indy TIdUDPServer) and allow to put the new data back to the X-Plane with a simple UDP Client (i.e. Indy TIdUDPClient).
The Unit generates the full packet ready to send.

It implements the TXPlane class with all 125 (x8) data variables in a simple way.

This unit saves the developer to write more than 10,000+ lines of code. (currently 9600 lines for DATA prolouge handling).

With external hardware you can easily control servos and all do you think, as well as read switches and send its states to the simulator.

procedure TForm1.IdUDPServer1UDPRead(Sender: TObject; AData: TBytes; ABinding: TIdSocketHandle);
var
  MyEngine1RPMs : single; //Note that all variables in X-Plane are single
  MyTaxiLight : boolean; //Offers support to boolean vars, it converts them internally
begin
   if XPlane.DataToProcess(AData) then
      begin
           MyEngine1RPM := XPlane.Engine1.RPM;
           MyTaxiLight  := XPlane.Switch.Electrical.Lights.TaxiON;		
      end;
end; 

with Xplane do
begin			
  BeginData(0); //You can specify the Data Index Byte. 
    Engine1.Generator.Amperes := 5.0;
    Battery1.SwitchON := True;
    Switch.Electrical.Lights.BeaconON := SpeedButton.Down;
  EndData;
end;
IdUDPClient.Send(Xplane.DataToSend); //XPlane.DataToSend is the data packet created
