使用 Flash 创建 pacman 风格的游戏 (AS3)

Question

使用 Flash (AS3) 创建 pacman 风格的游戏。有 3 名玩家竞争吃掉最多的点数。现在，当一个玩家吃掉一个点时，该玩家的屏幕上的点就会消失（但只持续一秒钟）并再次出现在屏幕上。正在玩的其他玩家没有看到该点消失并重新出现。

使用 hitTestObject，当玩家触摸某个点时，该点不应再在舞台上看到。我正在使用共享对象来创建这个多人游戏环境。我是使用 SharedObject 和 AS3 的新手。

            public function PlayerSelect()
                    {           
                        nc = new NetConnection();
                        nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
                        nc.connect("rtmp://r92kq5ew6.rtmphost.com/g1");

                        select_screen.btn1.addEventListener(MouseEvent.MOUSE_UP, select1);
                        select_screen.btn2.addEventListener(MouseEvent.MOUSE_UP, select2);
                        select_screen.btn3.addEventListener(MouseEvent.MOUSE_UP, select3);
                        for(var i=0; i<circ_num; i++) {
                            circle_ary[i] = new Circle(); //linkage in the library
                            circle_ary[i].x=0;
                            circle_ary[i].y=0;
                            stage.addChild(circle_ary[i]);
                        }

                    }

         public function netStatusHandler(event:NetStatusEvent):void
                {
                    trace("connected is: " + nc.connected );
                    trace("event.info.level: " + event.info.level);
                    trace("event.info.code: " + event.info.code);

                    switch (event.info.code)
                    {
                        case "NetConnection.Connect.Success":
                            trace("Congratulations! you're connected");
                            so = SharedObject.getRemote("ballPosition", nc.uri, false);
                            so.connect(nc);
                            so.addEventListener(SyncEvent.SYNC, syncHandler);
                            break;
                        case "NetConnection.Connect.Rejected":

                            trace ("Oops! you weren't able to connect");
                            break;
                    }

                }

                    so.setProperty("dots", pos_ary);
                }


            }

所有玩家都试图将棋盘写入游戏状态吗？如果是这样，那么当一个玩家吃掉一个点并将该地图写入游戏状态时，另一位玩家可能不会意识到游戏状态已更改并用该地图覆盖该地图。这意味着被吃掉的点会重新出现。
