TCP Socket Example

As of 2.6.0, Soldat Server Scripts are now able to establish TCP Connections.

NOTE: These features are only enabled when Safe Mode is turned off!
      Start the server with -safe 0 to disable Safe Mode.

Socket Related Functions:

- ConnectSocket
Use this function to create the socket and connect it. 
- CloseSocket
Disconnect a socket created with CreateSocket and destroy from memory.
- SendData
Send a string to a socket.
- ReadLnSocket
Read a line from a socket to a variable (Line end character is 0A (chr(10))

For your convenience, I have provided a basic example of how to put all these functions into practice.

 Usage: (Creates socket in a seperate thread)
  CreateSocket('127.0.0.1',23073);
 Use the OnDataReceived event below for any data parsing
}

var
 SocketIndex: Integer;
 SocketConnected: Array of Boolean;

procedure OnDataReceived(Index: Integer; Buffer: String);
begin
 if (Index = 0) or (SocketConnected[Index] = false) then exit; // Disconnected socket?
end;

procedure MainSocketLoop(Index: Integer);
var
 Buff: String;
begin
 while SocketConnected[Index] do begin
  ReadLnSocket(Index,Buff);
  if Buff <> '' then OnDataReceived(Index,Buff);
  sleep(1);
 end;
end;

procedure OnConnected(Index: Integer);
begin
 SetArrayLength(SocketConnected,GetArrayLength(SocketConnected)+2);
 ThreadFunc([Index],'MainSocketLoop');
 SocketConnected[GetArrayLength(SocketConnected)-1] := true;
end;

procedure OnDisconnected(Index: Integer);
begin
 SocketConnected[GetArrayLength(SocketConnected)-1] := false;
end;

procedure ThreadedCreate(IP: String;Port: Integer;var IndexVar: Integer);
begin
 ConnectSocket(IP,Port,IndexVar);
 OnConnected(IndexVar);
end;

procedure CreateSocket(IP: String;Port: Integer);
begin
 ThreadFunc([IP,Port,SocketIndex],'ThreadedCreate');
end;
