怎样用ASP实现网上“五子棋”大赛
“五子棋”是大家都非常熟悉的一种益智类游戏,相关的游戏软件也非常多,在此我向大家隆重推出一款新的纯“网络版”的五子棋,它利用ASP做为开发环境,因此在Internet上对战的时候无需下载客户端软件,只要你有一个浏览器就可以了。你也可以在局域网上进行这个游戏。
游戏的过程是这样的,我们首先登录,然后可以选择战场,有“金星”、“木星”、“水星”、“火星”、“土星”等五个战场,如果你自认为是一个高手,可以选择金星,否则可以依次选择其它几个星球做为战场。如果这个星球上没有擂主,你就应该以擂主的身份进入,然后别人就可以和你进行对战了。当然,如果所有的星球上都已经开始了战争,那么你就只能等一会儿了。
如果你是以擂主身份进入的,你可以等待别人来和你对战,如果你是以攻擂手的身份登录,你可以很快的和擂主展开战斗。开始战斗后,由擂主执黑先行,然后由攻擂手出招,如此这般。当最后决出胜负的时候,会有相应的提示。
该站点有几个主要的文件是:
Index.asp 登录文件:
Index0.asp中间文件:
Match.asp 比赛文件:
Back0.jpg white0.jpg black0.jpg 中间用到的图形文件,分别指的棋盘,白子和黑子,如下图:
在程序的初始化的时候,将棋盘上分成若干的表格,将背景图片放入其中,形成一个棋盘,然后在放上一个棋子后,再将图片换上相应的白子或黑子就可以了。
先看看登录文件:

这个文件不用做过多的说明,就是一个大的表格,大家可以从那里进入,如果某个位置已经被使用,则它会变成该大 侠的名字,不允许重复登录。在登录后进入
index0.asp,这是一个中间交换文件,在里面进行一些变量的处理及赋值,然后再进入match.asp,进行正式的比赛。我们来看一下index0.asp的内容:
<%@ Language=VBScript %>
<%
if Request.Form(“txt” & request.querystring(“flag”))<>”” then
‘response.write “in!” & “”
session(“nice”)=Request.Form(“txt” & request.querystring(“flag”))
‘response.write session(“nice”) & “”
‘response.write application(request.querystring(“flag”))
if application(request.querystring(“flag”))=”” then
application(request.querystring(“flag”))=session(“nice”)
session(“class”)=right(request.querystring(“flag”),1)
if left(request.querystring(“flag”),1)=”f” then
application(session(“nice”))=false
elseif left(request.querystring(“flag”),1)=”s” then
application(session(“nice”))=false
application(application(“first” & session(“class”)))=true
end if
Response.Redirect “match.asp”
end if
end if
%>
<HTML>
</HTML>
该程序中,用session(“nice”)来记录您登录的大名,以后的处理中,很多都要用到它,用它来区分很多的用户。如果您是从擂主的位置进入,则您的权利是
first,否则是second,用session(“class”)来记录位于哪个战场场,“金”“木”
“水”“火”“土”分别表示为1、2、3、4、5,因为有多个战场可能同时开战,如果不能正确地区分开,则可能导致一片混乱。application(session(“nice”))是一个逻辑型变量,用真假来表示您是否可以出棋,如果是假,您要等待一个,如果是真,您就可以下棋了。只有一个战场上的两个人都进入了以后,擂主方可以下棋,而且只有当擂主出子以后,攻擂手才可以下棋。准备好以后,下面就进入赛场,请看文件match.asp

如果某点没有棋子,则加上一个超连接,根据擂主与攻擂手的区别放上一个不同颜色的棋子。最后的一段是用来判断输与赢,分为横,列和两个斜线方向。具体内容看一下就可以明白。
最后要说的一点就是global.asa ,这是站点上的一个核心文件,为了在退出棋局后,将位置留给别人,需要在sesison_onend中加入代码进行处理,如下:
<script language=vbscript runat = server>
sub application_onstart
session.timeout=1
end sub
sub session_onstart
if application(“num”)=”” then
application(“num”)=0
end if
application(“num”)=application(“num”)+1
end sub
</script>
<script language=vbscript runat = server>
sub session_onend
if application(“num”)=”” then
application(“num”)=0
end if
application(“num”)=application(“num”)-1
if application(“first1”)=session(“nice”) then
application(“first1″)=””
elseif application(“second1”)=session(“nice”) then
application(“second1″)=””
elseif application(“first2”)=session(“nice”) then
application(“first2″)=””
elseif application(“second2”)=session(“nice”) then
application(“second2″)=””
elseif application(“first3”)=session(“nice”) then
application(“first3″)=””
elseif application(“second3”)=session(“nice”) then
application(“second3″)=””
elseif application(“first4”)=session(“nice”) then
application(“first4″)=””
elseif application(“second4”)=session(“nice”) then
application(“second4″)=””
elseif application(“first5”)=session(“nice”) then
application(“first5″)=””
elseif application(“second5”)=session(“nice”) then
application(“second5″)=””
end if
for i=1 to 15
for j=1 to 15
application(“color” & session(“class”) & “_” & cstr(i) & “_” & cstr
(J))=””
application(“pos” & session(“class”) & cstr(i) & “_” & cstr(j))=””
next
next
application(session(“nice”))=””
end sub
</script>
以上就是几个主要的文件,大家可以一试。
