LoadMission

When loading a mission there's a few lines of code as follows:

%conn = new GameConnection(ServerConnection);

   
   RootGroup.add(ServerConnection);
  
   %conn.setConnectArgs($pref::Player::Name, $pref::Player::Armor);
   %conn.setJoinPassword($Client::Password);
   %conn.connectLocal();

I looked for the function setConnectArgs, setJoinPassword, connectLocal everywhere in the scripts under common and mygame, can't find them. why? are they defined in the c++ engine only?


the reason I am asking is that I found two ways of loading a mission, the first one is calling loadMission:

function loadMission( %missionName, %isFirstMission ) 
{
  error("MissionName is "@%missionName);
  
   endMission();
   echo("*** LOADING MISSION: " @ %missionName);
   echo("*** Stage 1 load");
   echo("serverGroup is "@ServerGroup);
   // Reset all of these
   clearCenterPrintAll();
   clearBottomPrintAll();

   // increment the mission sequence (used for ghost sequencing)
   $missionSequence++;
   $missionRunning = false;
   $Server::MissionFile = %missionName;

   // Extract mission info from the mission file,
   // including the display name and stuff to send
   // to the client.
   buildLoadInfo( %missionName );

   // Download mission info to the clients
   %count = ClientGroup.getCount();
   for( %cl = 0; %cl < %count; %cl++ ) {
      %client = ClientGroup.getObject( %cl );
      if (!%client.isAIControlled())
         sendLoadInfoToClient(%client);
   }

   // if this isn't the first mission, allow some time for the server
   // to transmit information to the clients:
   if( %isFirstMission || $Server::ServerType $= "SinglePlayer" )
      loadMissionStage2();
   else
      schedule( $MissionLoadPause, ServerGroup, loadMissionStage2 );
}

the second one is

function SM_StartMission()
{
 
   %id = SM_missionList.getSelectedId();
   %mission = getField(SM_missionList.getRowTextById(%id), 1);
 
   if ($pref::HostMultiPlayer)
      %serverType = "MultiPlayer";
   else
      %serverType = "SinglePlayer";
   createServer(%serverType, %mission);
   %conn = new GameConnection(ServerConnection);
 
   
   RootGroup.add(ServerConnection);
  
   echo("playerName is " @ $pref::Player::Name@",player armor is "@ $pref::Player::Armor);
   %conn.setConnectArgs($pref::Player::Name, $pref::Player::Armor);
   %conn.setJoinPassword($Client::Password);
   %conn.connectLocal();
}

I am guessing that the first one is from the server and the second way is from the client. So if I want to be able to click on the button to load a mission file, should I use the second one instead of the first one? I am guess that connectLocal from client will eventually make the server call loadMission(), is this right?

thanks
