I use WME developed a  multiply players game.The server use JAVA +Tomcat+ SQL SERVER2000.player can login the server,chating each other,also can upon the game data to  server and query reports from server.player can see others moving,speaking in himself's client.here is the screenshot:

• game background:    
      This is a business  simulation RPG game,players(3-6 players) set up some  companies,each play acts a duty such as CEO,CFO,CTO and so on.
  Each company will receive a sum of money at the first,then every need to do lots of things:hire office,buy productlines,invite employees,buy materials,design and develop new products,sell products........., all of the companies will compete each other.
  
• game frame
      I decided to use WME to finish the game client.of course the game need a server program(i use java write some struts actions and use tomcat to run it,game data was stored into the sql server2000).
  
• network
      The WME client program can connect to the JAVA web server?yeah,it seems impossible if we only use itself's ability.so we use delphi writen a DLL file.There is some functions in the DLL,one of them called http_get(url,result),ok,now we can call it in the game script by follow  steps:
  1.declare the dll function in the base.script:
  external "gui.dll" int http_get(string,string);//arg1:http url address;arg2:return value
  2.we can call it like this:
  var rt=new String(100);
  http_get("http://www.dead-code.ogr/test.jsp?arg=1&arg=2&arg=3...",rt);
  we send our client program's data by arg=1&arg=2&arg=3...,and the server will return the result in variable  rt,our server sometime return a XML string and sometime return a split string(ex:"123#456#abc#def").
  we call DLL  function to  parse XML string and call WEM's String.Split(..) to parse split string.String.By the way,String.Split(..) has  more high performace than DLL XML function.
  
• GUI
      The WME itself's GUI is not strong,we use jsp web page(html,css,javascript....) to  implemented  most of the windows,the WME client open this page by call the DLL function http_webbrowser(url).This solution cause our game can only run in the window mode.........,but i think it's worthwhile.
  
• multiply player
       client  side
      Our WME Client  store the players in a global array:
      actors["tom"]=Game.LoadActor3D("actors\....\p.act3d");
      We can get every actor by their name:
      var act=actors["tom"];
      server side
      We have a table to store all player's location,scene....,each WME Client  need to report it's latest status and  get the players list from server  at a certain time rate(such as every 100ms),
  
  var rt=new String(2000);
  http_get("http://...../LoginAction.do?p0=9&p1="+courseid+"&p2="+companyid+"&p3="+studentid+"&scene="+Scene.Name+"&actor="+actor.Name+"&x="+actor.X+"&y="+actor.Y,rt);   
  by parasing the string rt. our client program can know how many actors are online,each one's location,scene,who are speaking,speaking what.....
  
• others
  how to display a custom text on the head of the actor?
  do it in the actor's script like this:
  
  var WinSubtitles;
  var tiptitle;
  while(1)
  {
  if(WinSubtitles==null)
  {
  WinSubtitles = Game.CreateWindow("subtitles_window");
  //WinSubtitles.SetImage("interface\bst\actor_card.tga");
  }
  if(tiptitle==null)
  {
  tiptitle= WinSubtitles.CreateStatic("speaker_name");
  tiptitle.SizeToFit();
  tiptitle.SetFont("fonts\arial_Í·²¿Ìáʾ-´Î.font");
  }
             // position the subtitles window
     WinSubtitles.X = this.X-Scene.OffsetX-32;
     WinSubtitles.Y = this.Y - this.Height-25;
     WinSubtitles.Width =100;
     WinSubtitles.Height = 45;
     WinSubtitles.Visible = this.Active;
     // position the speaker name
     tiptitle.X = 0;
     tiptitle.Y = 0;
     tiptitle.Width =WinSubtitles.Width;
     tiptitle.Height = WinSubtitles.Height;
     tiptitle.TextAlign = TAL_LEFT;
     tiptitle.VerticalAlign=VAL_TOP;
     tiptitle.Text =this.Caption;
    Sleep(20); 
  }
  
  how to use our cusutom talk method?
  do it in the actor's script like this:
  
  • 
    var subtitle;
    var msgtext;
    method MsgText(msg,t)
    {
    var l=msg.Length;
    if(l>84) return;
    var tt=t;
    if(subtitle==null)
    subtitle = Game.CreateWindow("subtitles_window1");
    if(msgtext==null)
    msgtext= subtitle.CreateStatic("speaker_name1");
    msgtext.ParentNotify=true;
    
    msgtext.SetFont("fonts\arial_?-?.font");   
    msgtext.TextAlign = TAL_LEFT;
    msgtext.VerticalAlign=VAL_CENTER;
    subtitle.Width =310;
    subtitle.Height =230;
    msgtext.Width =275;
    msgtext.Height =285;
    
    msgtext.Text =ToString(msg);
    subtitle.SetImage("interface\bst\msg1.png");
    subtitle.Width =55;
    subtitle.Height =35;
    msgtext.Width =40;
    msgtext.Height =25;
    msgtext.X =6;
    msgtext.Y =6;
    subtitle.Visible = this.Active;
    subtitle.MoveBefore(WinSubtitles);
    while(tt)
    {
    subtitle.Y = this.Y - this.Height-subtitle.Height;
    subtitle.X = this.X-Scene.OffsetX-28;
    Sleep(20);
    tt=tt-20;
    }
    subtitle.Visible=false;
    }

Thanks for the info, you rock man. Maybe you can help me later with a multiplayer game. Keep up the great work.

Cheers

I'd never expected to see a business simulation multi player game in wme (with a large addition of external code in this case). And the fact that you used wme for something which was not the primary design is impressive alone. Good work.
