游戏区其实就相当于一个游戏棋室的功能，从图7-4

。如果有人坐在左边就在左边显示一个小人，表示已经有人坐了，同理如果有人坐在右边就显示另一个小人。两个小人的样式如图7-6．检测玩家

首先先让这两个小人全部隐藏，然后在检查到名字变量不为空时就显示小人。

    this.gotoAndStop (2);

} else {

    this.gotoAndStop (1);

}

}

一张棋盘在源文件中的排列如图7-7左边的那个文本框是player_left左侧按钮

左边按钮的代码：

>求出我在100

             m_Message.attributes.VALUE = "http://www.dedecms.com/web-art/pingmianshejiruanjian/Flash/20060528/SIT";

             if (player_left == _root.nickname) {

                      //

           //

             } else if ((trim(player_left) == "" || player_left == null) && _root.myself.PlayStatus != "SitDown") {

                      _root.player_left[place] = player_left=_root.nickname;

                      _root.myself.PlayStatus = "SitDown";

                      _root.now_sit_table = place;

          //不管自己是坐下还是起立，都要发条信息给后台，并由后台进行广播

             chatXML.appendChild(m_Message);

             trace (chatXML.toString());

             // send it!!!

             if (_root.now_sit_table == place && player_right != _root.nickname ) {

                      //

                      if (trim(player_left) != "" && player_left != null && trim(player_right) != "" && player_right != null) {

              //谁拿什么棋，我现在在左边是拿红棋，对手拿右边的蓝棋

                                _root.my_logo = _root.First_play;

                                _root.your_logo = _root.Sec>表示玩家正坐在哪张台

                                _root.now_play_table = place;

              //

             }

    }

}

，然后把布尔变量对换。为了大家看得更加清楚，特列出程序如下：

;

                      _root.myself.PlayStatus = "StandUp";

                      m_Message.attributes.PARAM = place+" stand_up "+_root.nickname;

             } else if ((trim(player_right) == "" || player_right == null) && _root.myself.PlayStatus != "SitDown") {

                      _root.player_right[place] = player_right=_root.nickname;

                      _root.myself.PlayStatus = "SitDown";

                      _root.now_sit_table = place;

                      m_Message.attributes.PARAM = place+" right "+player_right;

             }

             chatXML.appendChild(m_Message);

             trace (chatXML.toString());

             // send it!!!

             if (_root.now_sit_table == place && player_left != _root.nickname) {

                      _root.chatSocket.send(chatXML);

                      _root.rival = "";

                      if (trim(player_left) != "" && player_left != null && trim(player_right) != "" && player_right != null) {

              //我在右边拿蓝棋，对手在左边拿红棋

                                _root.my_logo = _root.Sec>开始下棋

                                _root.begin_play(_root.nickname,_root.rival);

                                _root.gotoAndPlay("begin_play");

                      }

             } else {

                      //

这里的value           stand_up表示坐在棋盘左边

第三个则是用户的名称，后台根据这三项内容进行相应的处理。

处理完之后结果发回给用户：

<SIT VALUE="http://www.dedecms.com/web-art/pingmianshejiruanjian/Flash/20060528/6:stand_up:d>也是分成三个部分，只是其分隔符改成了冒号。
