5.需要知道如何辨别请求组队的职业

首先要知道一点，为了方便玩家使用，所以这个门派的得靠玩家来输入，详见上面如何获取用户输入内容。
但是玩家输入的内容可能是：
"少林，天策"或者是"少林天策"或者是"和尚TC"或者是"大师|TC"或者是"HS...天策"等等等等各种千奇百怪的叫法。
这种字串符的表达方式不能确认，这是非常麻烦的事情，我们就需要用到字串符处理的语法来解决这个问题。

为了简化例子，在这里插件中就不加入替换功能，大家可以自行尝试。

替换功能：
string.gsub(需要替换的原文,需要替换的字,替换后的字)
例：

local school = "" --不放nil是因为获取用户输入的为空的值是""而不是nil，如果一开始放nil在后面会增加判断的麻烦地方
school = string.gsub(school,"TC","天策") --替换TC为天策
school = string.gsub(school,"HS","少林") --替换过的字串符继续替换
school = string.gsub(school,"大师","少林") --同上
school = string.gsub(school,"和尚","少林") --最终完成的字串符

复制代码由于代码是从上往下执行的，先后顺序很重要
举个例子说明上面这段代码
假设school="TCHS大师和尚T，C大师和尚、HS"
那么在执行第二行后，这个school就变成"天策HS大师和尚T，C大师和尚、HS"
第三行后school="天策少林大师和尚T，C大师和尚、少林"
第四行后school="天策少林少林和尚T，C大师和尚、少林"
第五行后school="天策少林少林少林T，C大师少林、少林"
这便是替换功能。

查找功能
string.find(需要查找的原文,需要查找的字)
运用查找功能来进行比较

if string.find(school,g_tStrings.tForceTitle[arg2]) then
执行组队
end

由于school可以是个很不规则的字串符，但是只要找到哪怕一个匹配，上面这个判断式就成立。

例:

local school="天策少林少林少林T，C大师少林、少林"
if string.find(school,g_tStrings.tForceTitle[1]) then
Output("找到了")
else
Output("没找到")
end

因为g_tStrings.tForceTitle[1]是"少林"，school里面有少林存在，所以输出为"找到了"。
通过这样一个形式来统一用户输入格式，并且判断门派。

游客 2014-09-28 10:26: 1、春天，山坡的朝阳处雪开始融化，慢慢地露出黄黑色的地皮；雪水滋润着泥土，浸湿了去年的草楂；被雪盖着过了冬眠的草根苏醒复活了，渐渐地倔强有力地推去陈旧的草楂烂叶，奋力地生长起来。与此同时，去年秋天随风摇落下来的草木种子，也被湿土裹住，在孳殖着根须，争取它们的生命。山的背阴处虽然还寒气凛凛，可是寒冷的威力已在渐渐衰弱。朝阳处的温暖雪水顺着斜谷流过来，融化了硬硬的雪层，开始冲开山涧溪水的冰面。巨大的冻 ...; 引用
