What is the principle of more than 3 characters(movieclip)' meeting in cirrus(netstream)?

Hi.I'm JHS(Jeong Hyeon Seong).And I'd like to realize the program that can realize more than 3 characters meeting.

This is part of my source code of My fla,which is using cirrus.And which is able to chat more than 3 people,but cannot working for 3 characters(movieclip)' meeting

_sendstream.send('recvprot_chainfo',{ID:inum , xpos:u.x , ypos:u.y , xscale:u.scaleX , mapname:currentFrame , chacurf:u.currentFrame});

//u is my movieclip

//sendstream code,which is for sending the character's position,and xscale,and mapname(variable for preventing meeting for between another frame(field)'s character And current frame's I.),and character's currentframe(to realize character's various moving).

function pushrecvstream_f(newpeerid:String):void

{

//수신관련 함수

for (i=0; i<_recvstreamarray.length; i += 1)

{

  if (_recvstreamarray.farID == newpeerid)

  {

   return;

  }

}

var _newrecvstream:NetStream = new NetStream(_netconnection,newpeerid);

_newrecvstream.addEventListener(NetStatusEvent.NET_STATUS,netstatus_f);

var obj = new Object();

obj.recvprot_msg = function(e)

{

  msgsplus_f(e)

};

//chat receive function

obj.recvprot_nick = function(e)

{

  for(i=0;i<_userarray.length;i+=1){

   if(_userarray == e)

   {

    return;

   }

  }

   //chat receive function 2

  _userarray.push(e as String);

  msgsplus_f('추가');

  ulists.appendText(_userarray[_userarray.length-1]+'\n');

  _sendstream.send('recvprot_nick',nam.text)

};

obj.recvprot_delete = function(e)

{

  for(i=0;i<_userarray.length;i+=1)

  {

   if(e as String == _userarray)

   {

    msgsplus_f(_userarray+'사용자님이 접속을 종료하셨습니다.');

    _userarray.splice(i,1)

    break;

   }

  }

  ulists.text = _userarray[0];

  for(i=1;i<_userarray.length;i+=1)

  {

   ulists.appendText(_userarray+'\n');

  }

};

obj.recvprot_chainfo = function(e)

{

  for(i=0;i<_userarray.length;i+=1){

   if(_userarray == e)

   {

    return;

   }

  }

  if (e.ID != _netconnection.nearID)

  {

   if(currentFrame == e.mapname)

   {

    addChildAt(c,inum);

    c.x = e.xpos

       c.y = e.ypos

    c.scaleX = e.xscale

    c.gotoAndStop(e.chacurf);

    return;

   }

   else {removeChild(c);}

  }

};

//character's creating and moving code(This is most important code).

_newrecvstream.client = obj;

_newrecvstream.play(_groupname);

_recvstreamarray.push(_newrecvstream);

}

In this code,what can I do for more than 3 charater's meeting and moving?

When this problem got solved,I have no question for this part anymore.

Any help will be appreciated.Thank you.
